Referring to fig. 1 to 15, an electronic device provided in an embodiment of the present application includes: a

100, a

200 and an

300; the

200 comprises a driving assembly and a driven

201, wherein the driven

201 is positioned on the non-display end surface side of the

100; a first end of the elastic connecting

300 is connected with the

201, and a second end of the elastic connecting

300 is connected with the

100; wherein, in the process of the

100 transforming from the unfolded state to the folded state, the driving assembly drives the driven

201 to move in the direction away from the

100, and the elastic connecting

300 transforms from the compressed state to the stretched state; in the process of converting the

100 from the folded state to the unfolded state, the driving assembly drives the driven

201 to move in a direction close to the

100, and the elastic connecting

300 is converted from the stretched state to the compressed state.

The

100 includes a display end surface and a non-display end surface, where the non-display end surface may be an end surface opposite to the display end surface, and the display end surface is used for displaying data, such as displaying images and displaying characters.

The driven

201 may also be a connecting member, and is configured to connect the first end of the elastic connecting

300 and the motion output end of the driving assembly, so that the driving assembly moves and drives the elastic connecting

300 to perform a telescopic motion, and further the elastic connecting

300 can be changed between a telescopic state and a stretching state.

The driving assembly may be connected to the

100 through a transmission member, so that the driving assembly can move under the driving of the

100. Specifically, in the process of folding

100, the driving medium can transmit the rotary motion of

100 to the drive assembly, and then the drive assembly converts the received rotary motion into linear motion, thereby driving

201 to move towards or away from

100, and then realizing the technical effect that

300 can change between the telescopic state and the stretching state. In addition, the transmission member may convert the received rotational movement of the

100 into other types of movement, and then transmit the movement to the driving assembly.

Of course, the driving assembly may also independently drive the driven

201 to move, and in this case, the driving assembly may be a common structure capable of outputting a telescopic motion, and may be, for example, a linear motor, a crank-slider mechanism, a cam-link mechanism, or the like. Specifically, a detection element may be configured to detect a rotation angle of the

100, and when the rotation angle is greater than a preset value, it is determined that the

100 is folded or unfolded, and at this time, the detected signal is transmitted to a control unit of the electronic device, and the control unit controls the driving assembly to operate, so as to drive the driven

201 to move toward or away from the

100. Wherein, whether the

100 is to be unfolded or folded can be determined by detecting whether the angle of rotation of the

100 is increased or decreased. When the angle of the

100 is increased and the rotation angle is greater than the preset value, it is determined that the

100 is unfolded, and at this time, the driven

201 is driven by a driving assembly to move towards the

100; on the contrary, when the angle of the

100 is decreased and the rotation angle is greater than the preset value, it is determined that the

100 is folded, and at this time, the driven

201 is driven by the driving assembly to move away from the

100.

Alternatively, the

201 may be disposed opposite to the folding line when the folding screen is in the folded state, and the second end of the

300 may be connected to a position close to the folding line, so that the

201 stretches a redundant portion of the folding line position of the

100 to the outside in the process of converting the

100 from the unfolded state to the folded state, thereby preventing the problem that the folding line position is layered or creased due to local redundancy.

In addition, the

300 may be a spring. Thus, when the

300 is in a stretched state, an outward tensile force can be provided to the

100 due to the elastic force of the

300.

In this embodiment, in the process of folding the

100, the driving assembly drives the

201 to move away from the

100, so that the elastic connecting

300 is changed from a compression state to a tension state, that is, when the

100 is in a folded state, the elastic connecting

300 is in the tension state, and thus, under the action of the tensile force of the elastic connecting

300, the redundant part of the folded position of the

100 is stretched, thereby effectively relieving the problem of damage to the folded screen due to the layering phenomenon occurring at the folded position in the process of folding the

100. In addition, when the

100 is in the unfolded state, the elastic connecting

300 is in the stretched state, and at this time, the elastic connecting

300 can effectively support the

100, so that the

100 is prevented from being automatically folded under the action of self gravity.

Optionally, the

201 includes an elastic carrier plate, a first end of the elastic connecting

300 is connected to a side of the elastic carrier plate facing the

100, and the driving assembly is connected to a side of the elastic carrier plate facing away from the

100;

in the process of folding or unfolding the

100, the driving assembly drives the elastic carrier plate to switch between the first deformation state and the second deformation state, and the elastic connecting

300 switches between the compression state and the extension state.

The elastic carrier plate may be a common elastic plate body, for example, a steel plate, a copper plate, an elastic plastic plate, or the like. Above-mentioned elastic carrier plate can with electronic equipment's shell connection, for example, can the inside of casing sets up two spliced poles to with the both ends of elastic carrier plate fixed connection respectively in two the spliced pole, wherein, can with two the distance of spliced pole sets up to being less than elastic connecting plate's length, like this, work as when elastic connecting plate's both ends are fixed in two spliced poles, elastic connecting plate will have two kinds of deformation states, and the deformation state of encircleing towards

100 promptly and the state of encircleing

100 dorsad, these two kinds of deformation states can do respectively first deformation state and second deformation state. For convenience of description, a deformation state in which the elastic connection plate is arched toward the

100 is referred to as the first deformation state, and a deformation state in which the elastic connection plate is arched away from the

100 is referred to as the second deformation state. The elastic carrier plate can be switched between the first deformation state and the second deformation state by pushing or pulling the elastic carrier plate through the driving assembly, so that the elastic connecting

300 is switched between the compression state and the extension state.

Optionally, the

100 comprises a first portion and a second portion, the first portion and the second portion being symmetrically distributed about a first axis of symmetry about which at least one of the first portion and the second portion rotates during folding or unfolding of the

100;

the electronic device comprises a plurality of the elastic connecting

300, and the plurality of the elastic connecting

300 are symmetrically arranged about the first symmetry axis.

Wherein, first symmetry axis can be

100 is to broken line when fold condition the in-process that the elasticity support plate switches between first deformation state and second deformation state, and is a plurality of equal simultaneous movement of

300 just keeps the same elastic state all the time. Specifically, when the elastic carrier is in the first deformation state, each elastic connecting

300 is in a compressed state, whereas when the elastic carrier is in the second deformation state, each elastic connecting

300 is in a stretched state.

In this embodiment, the plurality of

300 are symmetrically arranged about the pair of folding lines, so that when the

100 is in the folded state, the

100 is stretched outward from different directions by the

300, and the

100 is stretched at the position of the pair of folding lines by the elastic force of the

300 to form the shape shown in fig. 3. Because the position of the folding line is expanded, the phenomenon that the position of the folding line is layered in the process of folding the

100 is avoided. In addition, because the position of the folding line is unfolded, the screen on two sides of the folding line is also prevented from being folded along the folding line directly to form a crease, and the phenomenon of layering of the position of the folding line is further avoided.

Optionally, the plurality of

300 includes at least two

300 with different free lengths, and the free lengths of the

300 are gradually increased along a direction away from the first symmetry axis, wherein the free length of the

300 is the length of the

300 in a free state.

The length of the

300 in the free state may refer to a length of the

300 when it is not applied by an external force.

When the

201 is an elastic carrier plate, please refer to fig. 6, since the elastic carrier plate is arched from the middle, when the

100 is in the unfolded state, distances between positions of the elastic carrier plate and the

100 are different. Therefore, in order to ensure that the supporting force of the

100 by the

300 at each position is relatively uniform, the length of the

300 can be determined by connecting the

300 with different free lengths at different positions of the elastic carrier plate, for example, according to the distance between the position where each

300 is connected to the

100 and the first symmetry axis, and the

300 are selected to be relatively longer as the connection position is farther from the first symmetry axis.

It should be noted that, since the plurality of

300 are symmetrical about the first symmetry axis, the free lengths of the

300 at the symmetrical positions of the first symmetry axis may be the same, thereby further ensuring that the supporting force of the

300 at both sides of the first symmetry axis to the

100 is relatively uniform when the

100 is in the unfolded state.

Optionally, the drive assembly comprises a

204, a

202 and a

203;

204 is connected with the

202 to drive the

202 to rotate;

202, and a first

206 may be disposed in the second shaft hole, wherein the first

206 is disposed in parallel with the driving

204, so that the first end of the connecting

203 may be rotatably coupled to the

202 through the first

206. In addition, the second end of the connecting

203 may be rotatably connected to the elastic carrier plate through a third

205, specifically, a support for connecting to the third

205 may be disposed on a side of the elastic carrier plate away from the

100, the third

205 may be rotatably connected to the support, and then the second end of the connecting

203 is connected to the third

205, that is, the second end of the connecting

203 and the elastic carrier plate may be rotatably connected.

During the rotation of the driving

204, the connecting

203 will move in a plane with the

202, as shown in fig. 7, when the first

206 moves to the highest point, the elastic carrier plate moves to the first elastic deformation state, as shown in fig. 8, when the first

206 moves to the lowest point, the elastic carrier plate moves to the second elastic deformation state. In the process that the first

206 moves from the highest point to the lowest point, the elastic carrier gradually changes from the first elastic deformation state to the second elastic deformation state, and conversely, in the process that the first

206 moves from the lowest point to the highest point, the elastic carrier gradually changes from the second elastic deformation state to the first deformation state.

The driving

204 can be driven to rotate by the folding or unfolding motion of the

100, and the driving

204 can also be driven to rotate by a driving member, for example, the driving assembly may further include a motor, an output shaft of the motor is the driving

204, so that the driving

204 is driven to rotate by the motor.

203 are arranged to drive the elastic connecting

400 is rotated in a direction toward the

500; in the process of changing the

100 from the folded state to the unfolded state, the

400 rotates in a direction away from the

500.

400 and the

500 through the first connecting

501, so that the elastic carrier is separated from the

400 and the

Optionally, the electronic device further includes a first

600 and a second

700, the

100 includes a

101 and a

102, the

102 is located between the first

700, and the first

600, the

102 and the second

700 are all attached to the non-display end surface of the

101; a second end of the

102.

In this embodiment, the first

600 and the second

700 may be made of a steel plate, a hard plastic plate, or the like. The

102 may be a plate-like structure capable of being deformed so that the

102 is folded during the folding process of the

100. In addition, the first

600 and the second

700 attached to the

100. Wherein the first

600, the

102 and the second

700 are connected in sequence.

Referring to fig. 13, a connection state diagram of the first

600, the

102 and the second

700 when the

102 are respectively fixed to the first

600 and the second

700, and lower ends of two adjacent strip-shaped plates 701 are abutted, the

102 cannot continue to bend and deform upwards under the elastic force of the elastic connecting

300, that is, the

102 cannot arch and deform upwards, thereby ensuring the flatness of the

100 in the unfolded state. Since the second rotating shaft 702 between the two adjacent strip-shaped plates 701 is located at an end close to the

100, in the process of folding the

100, the two adjacent strip-shaped plates 701 can rotate around the second rotating shaft 702 between the two adjacent strip-shaped plates 701, so that the

102 is arched downwards to form the state shown in fig. 3.

In this embodiment, the

102 is configured as above, so that the

102 can only move to the horizontal state toward the

100, and can move to the arched state away from the

100. In this way, the flatness of the

100 is ensured when the

100 is in the unfolded state, and the

102 can be folded together with the

100 during the folding process of the

100. In addition, the first

600, the

102 and the second

700 are connected in sequence, so that the problem of poor support effect caused by the formation of a gap between the rigid support plate and the

102 is solved.
