When the
linkage mechanism26 bends, the one
link member261 is rotated toward the
other link member261, and the
first gear2661 of the one
link member261 rotates along the corresponding
second gear2663; because the
fixing block2621 of the fixing
member262 and the second connecting
shaft2620 are relatively fixed, and the
second gear2663 is fixed on the
fixing block2621, the
second gear2663 is fixed and cannot rotate, and the
first gear2661 can only rotate around the corresponding
second gear2663, so that the one
link member261 rotates along the corresponding
second gear2663, and thus the two
transmission members264 connected to the one
link member261 are driven to rotate along the corresponding second connecting
shaft2620 and the corresponding damping
member268 is driven to rotate along the corresponding second connecting
shaft2620; the two
transmission members264 drive the other two
transmission members264 to rotate along the corresponding second connecting
shafts2620 through the
second gear assembly267, and the other two
transmission members264 drive the other connecting
rod261 to rotate around the corresponding
second gear2663, so that the two connecting
rod261 approach each other and are bent at the same time. In the linkage process, each of the first connecting
shaft2610 and the second connecting
shaft2620 is in interference fit with the corresponding damping
hole2683 of the damping
plate2681, so that the damping
member268 can rotate and position the two
link members261 at any angle.
In other usage manners, the two
link members261 can be rotated together in opposite directions, the
first gears2661 of the two
link members261 rotate around the corresponding
second gears2663 to drive the
transmission members264 to rotate in opposite directions along the corresponding second connecting
shafts2620, and also drive the two damping
members268 to rotate in opposite directions along the corresponding second connecting
shafts2620, so that the two
link members261 are simultaneously moved close to each other and bent.
When the linkage 26 is flattened from the bent state, the one link 261 is rotated away from the other link 261, and the first gear 2661 of the one link 261 rotates along the corresponding second gear 2663; because the fixing block 2621 of the fixing member 262 and the second connecting shaft 2620 are relatively fixed, and the second gear 2663 is fixed on the fixing block 2621, the second gear 2663 is fixed and cannot rotate, and the first gear 2661 can only rotate around the corresponding second gear 2663, so that the one of the connecting rod pieces 261 rotates away from the other connecting rod 261 along the corresponding second gear 2663, so as to drive the two transmission members 264 connected to the one of the connecting rod pieces 261 to rotate away from each other along the corresponding second connecting shaft 2620 and drive the corresponding damping member 268 to rotate away from each other along the corresponding second connecting shaft 2620; the two transmission members 264 drive the other two transmission members 264 to rotate along the corresponding second connecting shafts 2620 through the second gear assemblies 267, and the other two transmission members 264 drive the other connecting rod 261 to rotate around the corresponding second gears 2663 toward the direction away from the one of the connecting rods 261, so that the two connecting rod 261 are simultaneously away from each other to be flattened. In the linkage process, each of the first connecting
shaft2610 and the second connecting
shaft2620 is in interference fit with the corresponding damping
hole2683 of the damping

rotating hinges253 rotate through a second virtual axis a2, the second virtual axis a2 is located between the two first virtual axes a1, and the two first virtual axes a1 are respectively at the same distance from the second virtual axis a 2. The two connecting
hinges251 rotate around the corresponding first virtual axes a1, and the
first positioning component28a and the
second positioning component28b also rotate around the first virtual axis a1 along with the corresponding connecting
hinges251; the two
rotating hinges253 rotate around the second virtual axis a2, the
first transmission assembly271, the corresponding connecting
cover270 and the
third transmission assembly277 rotate around the second virtual axis a2 along with the corresponding
rotating hinge253, and the
second transmission assembly274, the corresponding connecting
cover270 and the
third transmission assembly277 rotate around the second virtual axis a2 along with the corresponding
rotating hinge253. Specifically, since the
first transmission assembly271, the corresponding connecting
cover270, the
third transmission assembly277 connected to the connecting
cover270, and the corresponding
rotating hinge253 are connected to a unitary structure, the unitary structure rotates about the second virtual axis a 2; since the
second driving unit274, the
corresponding connection cover270, the
third driving unit277 connected to the
connection cover270, and the
corresponding rotation hinge253 are connected to a unitary structure, the unitary structure is also rotated about the second virtual axis a 2. Each first virtual axis A1 is spaced parallel to the second virtual axis A2, and the first virtual axis A1 has the same axis radius as the second virtual axis A2. In the flattened state, the distance between two opposite side surfaces of the two connecting
hinges251 is L, that is, the straight line distance between two side surfaces of the two connecting
hinges251 at the bending outer sides in the flattened state is L. In this embodiment, the distance between two opposite sides of the two connecting
hinges251 is equal to the width of the
bendable region31, i.e. the length of the
bendable region31 extending in a direction perpendicular to the first virtual axis a1 is equal to L. The first virtual axis a1 and the second virtual axis a2 are located outside the hinge
main body25, and preferably, the first virtual axis a1 and the second virtual axis a2 are located on the
flexible screen30 covering the hinge
main body25, so that the bending resistance of the
flexible screen30 can be improved, and the
flexible screen30 can be prevented from being damaged to the maximum extent. Further, a1 and a2 may also be located on the neutral layer of the flexible screen.
The neutral layer is that the outer layer of the
flexible screen30 is stretched, the inner layer of the
flexible screen30 is extruded, a transition layer which is not stretched, not extruded or stretched or extruded has relatively small acting force is arranged on the section of the transition layer, the stress of the transition layer is little, and the transition layer is the neutral layer.
Each virtual axis is defined by a corresponding structure. Specifically, the virtual axis a1 may be defined by the axis of the arc of the bottom of the receiving
slot2737 or by the axis of the arc of the bottom of the
link2836; the virtual axis a2 may be defined by the axis of the arc-shaped guide surface at the bottom of the connecting
block2738 or the axis of the arc-shaped guide surface at the inner wall of the receiving
groove2767.
The
flexible screen30 is attached to the top of the curved face of each articulation/swivel/locating assembly/linkage in the deployed condition and is spaced from the other regions of the curved face beyond the top of each curved face. By the above-mentioned virtual axis scheme, the
flexible screen30 can keep the length substantially unchanged when being bent.
Because the inner surface of the sliding
slot2816 of the first mounting
element281 is provided with the circular arc-shaped
receiving slot2817 and the inner surface of the sliding
slot2856 of the second mounting
element285 is provided with the circular arc-shaped
receiving slot2857, in the process of bending or flattening the
hinge device24, the
guide posts2616 of the two connecting
rods2611 can respectively slide in the receiving
slots2817 and 2857, so that the opening thicknesses of the sliding
slots2816 and 2856 can be reduced, and further the thicknesses of the first mounting
element281 and the second mounting
element285 can be reduced, so that the thickness of the whole
electronic device100 can be reduced.
Because the straight rack and the straight gear are meshed for linkage, compared with the mode of meshing and linking by the bevel gear, the method does not need high manufacturing precision, can effectively reduce the production cost and improve the production efficiency.
It is understood that the spur rack in each of the
first gear assembly266 and the
second gear assembly267 can be replaced by a helical gear or a spur gear, the spur gear can be replaced by a helical gear, or the spur rack in each gear assembly can be omitted, and the spur rack can be directly engaged by two spur gears, which can also achieve the purpose of linkage.
The
hinge device24 is placed between the
first frame21 and the
second frame23, that is, the
slide rail2813 of the
first positioning unit28a and the connecting
piece2853 of the
second positioning unit28b of the two connecting
links251 are connected to the
first frame21 and the
second frame23, respectively. The back surfaces of the two
non-bent regions33 of the
flexible panel30 are respectively attached to the
first frame21 and the
second frame23, and the back surface of the
bendable region31 of the
flexible panel30 is attached to the front surface of the
hinge device24. At this time, the
first snap member283 and the
second snap member286 of the
hinge device24 are fixed relative to the back surface of the
flexible screen30, and the
bendable region31 of the
flexible screen30 can be bent along with the bending of the
hinge device24.
Referring to fig. 23 to 27, when the
electronic device100 is bent, a bending force is applied to at least one of the
first frame21 and the
second frame23 of the
electronic device100, so that the connecting
links251 connected to the
first frame21 and the
second frame23 rotate in a direction adjacent to each other, and the
first positioning assemblies28a and the corresponding
second positioning assemblies28b rotate in a direction adjacent to each other. Specifically, if a bending force is applied to the first frame body 21, the first frame body 21 drives the corresponding connecting hinge 251 and the first positioning assemblies 28a at the two ends of the connecting hinge 251 to rotate relative to the rotating hinge 253 along the first virtual axis a1 toward the side away from the flexible screen 30; the two first positioning assemblies 28a drive the first gears 2661 of the two link members 261 to rotate along the corresponding second gears 2663, respectively, because the fixing block 2621 of the fixing member 262 and the second connecting shaft 2620 are relatively fixed, and the second gears 2663 are fixed on the fixing block 2621, the second gears 2663 and the second connecting shaft 2620 are both fixed and do not rotate, the first gears 2661 can only rotate around the corresponding second gears 2663 towards the side far away from the flexible screen 30, so that the link members 261 rotate along the second gears 2663 towards the side far away from the flexible screen 30, and the connecting rods 2611 and the guide posts 2616 of the link members 261 slide in the corresponding sliding slots 2816 and receiving slots 2817 of the first mounting member 281; meanwhile, the link 261 drives the two corresponding transmission members 264 and the corresponding damping members 268 to rotate along the corresponding second connecting shaft 2620 toward the side away from the flexible screen 30, the transmission posts 2644 of the two transmission members 264 slide in the corresponding toggle grooves 2726 and 2786 respectively, so as to drive the first transmission assembly 271 and the corresponding third transmission assembly 277 to rotate along the second virtual shaft a2 toward the side away from the flexible screen 30, and the first transmission assembly 271 drives the corresponding rotating hinge 253 to rotate along the second virtual shaft a2 toward the side away from the flexible screen 30; the two transmission members 264 drive the other two transmission members 264 to rotate along the corresponding second connecting shafts 2620 towards the side away from the flexible screen 30 through the second gear assemblies 267, the other two transmission members 264 drive the other connecting rod 261 and the other damping member 268 to rotate towards the side away from the flexible screen 30, and as the fixing block 2621 of the fixing member 262 and the second connecting shaft 2620 are relatively fixed and the second gear 2663 is fixed on the fixing block 2621, the second gear 2663 is fixed and cannot rotate, the first gear 2661 of the other connecting rod 261 can only rotate around the corresponding second gear 2663 towards the side away from the flexible screen 30, so that the connecting rod 2611 of the other connecting rod 261 rotates along the second gear 2663 towards the side away from the flexible screen 30; the link 2611 and the guide post 2616 of the other link 261 slidably push the corresponding slide slot 2856 and the corresponding accommodating slot 2857 of the second mounting element 285, so that the second positioning assembly 28b and the second frame 23 rotate along the corresponding first virtual axis toward a side a1 away from the flexible screen 30; meanwhile, the driving posts 2644 of the other two driving members 264 slide in the corresponding toggle slots 2756, 2786 respectively, so as to drive the second driving component 274 and the corresponding third driving component 277 to rotate towards the side away from the flexible screen 30, and the second driving component 274 drives the corresponding rotating hinge 253 to rotate towards the side away from the flexible screen 30 along the second virtual axis a 2. The
bendable region31 of the
flexible screen30 bends with the
hinge assembly24 until the
first frame21 abuts the back of the
second frame23.
At this time, the
hinge device24 is bent, and the
flexible screen30 is bent along with the
hinge device24, so that the front surface of the
connection hinge251, the front surface of the
rotation hinge253, the front surface of the
first transmission component271, the front surface of the
second transmission component274, and the front surface of the
third transmission component277 are connected to each other to form an arched surface, so as to facilitate the attachment of the
flexible screen30. As shown in fig. 27, the distance between the two opposite sides of the connecting
hinge251 of the
hinge body25 in the bent state along the bending outer side of the
hinge body25 is also L, that is, the straight line distance between the two connecting
hinge251 of the
hinge body25 located on the bending outer side in the unfolded state is equal to the distance along the bending outer side of the
hinge body25 in the folded state, so that the width of the
bendable region31 of the
flexible screen30 covering the
hinge body25 in the bent state is equal to the width in the unfolded state, and the
flexible screen30 can be prevented from being damaged by being extruded or stretched. When the
hinge body25 is in the bent state, the first virtual axis a1 and the second virtual axis a2 are both located outside the
hinge body25, and preferably, the first virtual axis a1 and the second virtual axis a2 are located on a neutral layer of the
flexible screen30 that covers the
hinge body25. The first virtual axis a1 and the second virtual axis a2 of the hinge
main body25 of the present invention are both located on the neutral layer when the
electronic device100 is bent or flattened, so as to ensure that the
flexible screen30 is not damaged to the maximum extent.
In the bending process of the
hinge device24, the two first connecting
shafts2610 respectively rotate in the damping
holes2683 of the two damping
members268, each damping
member268 is far away from the
elastic retainer ring2684 of the corresponding first connecting
shaft2610 and is rotatably sleeved on the corresponding second connecting
shaft2610, and because the first connecting
shaft2610 and the second connecting
shaft2620 are respectively inserted in the corresponding damping
member268 in an interference fit manner, the
hinge device24 can be positioned at any angle in the bending process, the distance between two opposite side surfaces of the two connecting
hinge joints251 of the hinge
main body25 bent at any angle cannot be changed, that is, the width of the
bendable region31 of the
flexible screen30 bent at any angle cannot be changed, the
screen30 is prevented from being damaged due to the protrusion or stretching of the
flexible screen30 in the bending or flattening process, and the
flexible screen30 can be ensured not to be damaged to the maximum extent.
In other bending manners of the electronic device 100, only a bending force may be applied to the second frame 23, and the second frame 23 drives the corresponding connection hinge 251 and the second positioning assemblies 28b at two ends of the connection hinge 251 to rotate along the first virtual axis relative to the rotation hinge 253 toward a side away from the flexible screen 30; the second positioning assembly 28b drives the first gears 2661 of the two link members 261 to rotate around the corresponding second gears 2663 respectively towards the side away from the flexible screen 30, so that the link members 261 rotate towards the side away from the flexible screen 30 along the second gears 2663, and the link 2611 and the guide post 2616 of the link member 261 slide in the corresponding slide slot 2856 and the corresponding accommodating slot 2857 of the second mounting member 28; meanwhile, the link 261 drives the two corresponding transmission members 264 and the corresponding damping members 268 to rotate along the corresponding second connection shafts 2620 toward the side away from the flexible screen 30, the transmission posts 2644 of the two transmission members 264 drive the second transmission assembly 274 and the corresponding third transmission assembly 277 to rotate toward the side away from the flexible screen 30, and the second transmission assembly 274 drives the corresponding rotation hinge 253 to rotate along the second virtual shaft toward the side away from the flexible screen 30; the two transmission members 264 drive the other two transmission members 264 to rotate along the corresponding second connecting shafts 2620 together to a side away from the flexible screen 30 through the second gear assembly 267, the other two transmission members 264 drive the first gear 2661 of the other connecting rod 261 to rotate around the corresponding second gear 2663 to a side away from the flexible screen 30, and the other damping member 268 rotates along the corresponding second connecting shaft 2620 to a side away from the flexible screen 30; the connecting rod 2611 and the guide post 2616 of the other connecting rod 261 slidably push the corresponding sliding slot 2816 and receiving slot 2817 of the first mounting part 281, so that the first positioning assembly 28a and the first frame 21 rotate along the first virtual axis towards the side away from the flexible screen 30; meanwhile, the transmission posts 2644 of the other two transmission members 264 respectively slide in the corresponding toggle grooves 2726 and 2786 to drive the first transmission assembly 271 and the corresponding third transmission assembly 277 to rotate towards the side away from the flexible screen 30, and the first transmission assembly 271 drives the corresponding rotation hinge 253 to rotate towards the side away from the flexible screen 30 along the second virtual axis. The
bendable region31 of the
flexible screen30 bends with the
hinge assembly24 until the
first frame21 abuts the back of the
second frame23. In the bending process of the
hinge device24, the two first connecting
shafts2610 respectively rotate in the damping
holes2683 of the two damping
members268, each damping
member268 is far away from the corresponding
elastic retainer ring2684 of the first connecting
shaft2610 and is rotatably sleeved on the corresponding second connecting
shaft2610, and the first connecting
shaft2610 and the second connecting
shaft2620 are respectively inserted into the corresponding damping
members268 in an interference fit manner, so that the
hinge device24 can be positioned at any angle in the bending process.
In other bending manners of the
electronic device100, a bending force may be applied to the
first frame21 and the
second frame23 at the same time, and the
first frame21 and the
second frame23 respectively drive the corresponding
connection hinge251 to rotate towards a side away from the
flexible screen30 relative to the
rotation hinge253, so as to realize bending of the
electronic device100.
When the
electronic device100 needs to be flattened, the
first frame21 or the
second frame23 is pulled outward, and the connecting
links251 connected to the
first frame21 and the
second frame23 are rotated in a direction away from each other. Specifically, a force that pulls at least one of the
first frame21 and the
second frame23 of the
electronic device100 outward is applied, so that the connecting
links251 connected to the
first frame21 and the
second frame23 rotate in a direction away from each other, and the
first positioning assemblies28a and the corresponding
second positioning assemblies28b rotate in a direction away from each other. If a force pulling outward is applied to the first frame body 21, the first frame body 21 drives the corresponding connecting hinge 251 and the first positioning components 28a at the two ends of the connecting hinge 251 to rotate relative to the rotating hinge 253 towards one side of the flexible screen 30; the two first positioning assemblies 28a drive the first gears 2661 of the two link members 261 to rotate along the corresponding second gears 2663, respectively, because the fixing block 2621 of the fixing member 262 and the second connecting shaft 2620 are relatively fixed, and the second gears 2663 are fixed on the fixing block 2621, the second gears 2663 are fixed and do not rotate, the first gears 2661 can only rotate around the corresponding second gears 2663 towards one side of the flexible screen 30, so that the link members 261 rotate along one side of the flexible screen 30 along the second gears 2663, and the connecting rods 2611 and the guide posts 2616 of the link members 261 slide in the corresponding sliding slots 2816 and receiving slots 2817 of the first mounting member 281; meanwhile, the link 261 drives the two corresponding transmission members 264 and the corresponding damping members 268 to rotate towards one side of the flexible screen 30 along the corresponding second connecting shafts 2620, the transmission posts 2644 of the two transmission members 264 slide in the corresponding toggle grooves 2726 and 2786 respectively to drive the first transmission assembly 271 and the corresponding third transmission assembly 277 to rotate towards one side of the flexible screen 30, and the first transmission assembly 271 drives the corresponding rotating hinge 253 to rotate towards one side of the flexible screen 30 along the second virtual shaft; the two transmission members 264 drive the other two transmission members 264 to rotate along the corresponding second connecting shafts 2620 toward one side of the flexible screen 30 through the second gear assemblies 267, the other two transmission members 264 drive the other connecting rod 261 and the other damping member 268 to rotate along the corresponding second connecting shafts 2620 toward one side of the flexible screen 30, and since the fixing block 2621 of the fixing member 262 and the second connecting shafts 2620 are relatively fixed and the second gear 2663 is fixed on the fixing block 2621, the second gear 2663 is fixed and cannot rotate, the first gear 2661 of the other connecting rod 261 can only rotate around the corresponding second gear 2663 toward one side of the flexible screen 30, so that the connecting rod 2611 of the other connecting rod 261 rotates along the second gear 2663 toward one side of the flexible screen 30; the connecting rod 2611 and the guide post 2616 of the other connecting rod 261 slidably push the corresponding slide slot 2856 and accommodating slot 2857 of the second mounting member 285, so that the second positioning assembly 28b and the second frame 23 rotate along the first virtual axis toward one side of the flexible screen 30; the driving posts 2644 of the other two driving members 264 slide in the corresponding toggle slots 2756, 2786 respectively, so as to drive the second driving component 274 and the corresponding third driving component 277 to rotate along the second virtual axis toward one side of the flexible screen 30, and the second driving component 274 drives the corresponding rotating hinge 253 to rotate along the second virtual axis toward one side of the flexible screen 30. The
bendable region31 of the
flexible screen30 flattens with the
hinge arrangement24. In the process of flattening the
hinge device24, the two first connecting
shafts2610 rotate in the damping
holes2683 of the two damping
members268, the
elastic retainer rings2684 of each damping
member268, which are far away from the corresponding first connecting
shaft2610, are rotatably sleeved on the corresponding second connecting
shaft2610, and the first connecting
shaft2610 and the second connecting
shaft2620 are respectively inserted into the corresponding damping
members268 in an interference fit manner, so that the
hinge device24 can be positioned at any angle in the process of flattening. Because the distance between the two opposite side surfaces of the two connecting
hinge joints251 bent or unfolded to any angle of the hinge
main body25 is not changed, that is, the width of the
bendable region31 of the
flexible screen30 bent or unfolded to any angle is not changed, the screen can be prevented from being damaged due to the protrusion or stretching of the
flexible screen30 in the bending or unfolding process of the
flexible screen30, and the
flexible screen30 can be ensured not to be damaged to the maximum extent.
In other flattening manners of the electronic device 100, only the second frame 23 may be pulled outward, and the second frame 23 drives the corresponding connecting hinge 251 and the second positioning assemblies 28b at two ends of the connecting hinge 251 to rotate relative to the rotating hinge 253 toward one side of the flexible screen 30; the second positioning assembly 28b drives the first gears 2661 of the two link members 261 to rotate around the corresponding second gears 2663 toward one side of the flexible screen 30, so that the link members 261 rotate along the second gears 2663 toward the side of the flexible screen 30, and the link 2611 and the guide post 2616 of the link member 261 slide in the corresponding slide slot 2856 and the receiving slot 2857 of the second mounting member 28; meanwhile, the link 261 drives the two corresponding transmission members 264 and the corresponding damping members 268 to rotate along the corresponding second connection shafts 2620 toward one side of the flexible screen 30, the transmission posts 2644 of the two transmission members 264 drive the second transmission assembly 274 and the corresponding third transmission assembly 277 to rotate along the second virtual shaft toward one side of the flexible screen 30, and the second transmission assembly 274 drives the corresponding rotation hinge 253 to rotate along the second virtual shaft toward one side of the flexible screen 30; the two rotating transmission members 264 drive the other two transmission members 264 to rotate along the corresponding second connecting shafts 2620 towards one side of the flexible screen 30 through the second gear assemblies 267, the other two transmission members 264 drive the first gear 2661 of the other connecting rod 261 to rotate around the corresponding second gear 2663 towards one side of the flexible screen 30, and the other damping member 268 rotates along the corresponding second connecting shaft 2620 towards one side of the flexible screen 30; the connecting rod 2611 and the guide post 2616 of the other connecting rod 261 slidably push the corresponding sliding slot 2816 and receiving slot 2817 of the first mounting part 281 to make the first positioning assembly 28a and the first frame 21 rotate along the first virtual axis toward one side of the flexible screen 30; meanwhile, the transmission posts 2644 of the other two transmission members 264 slide in the corresponding toggle slots 2726 and 2786 respectively to drive the first transmission assembly 271 and the corresponding third transmission assembly 277 to rotate along the second virtual axis toward one side of the flexible screen 30, and the first transmission assembly 271 drives the corresponding rotation hinge 253 to rotate along the second virtual axis toward one side of the flexible screen 30.

hinge device24, the two first connecting
shafts2610 rotate in the damping
holes2683 of the two damping
members268, the
elastic retainer rings2684 of each damping
member268, which are far away from the corresponding first connecting
shaft2610, are rotatably sleeved on the corresponding second connecting
shaft2610, and the first connecting
shaft2610 and the second connecting
shaft2620 are respectively inserted into the corresponding damping
members268 in an interference fit manner, so that the
hinge device24 can be positioned at any angle in the process of flattening.

electronic device100, a force for pulling the
first frame21 and the
second frame23 outward may be applied to the
first frame21 and the
second frame23 simultaneously, and the
first frame21 and the
