bevel gear

410 and the

first tooth structure

510.

Referring to fig. 9, the

screen assembly

300 includes a first section and a second section, and the first section and the second section are connected. Illustratively, a first section of the

screen assembly

300 is disposed in the

first housing

100, and a second section of the

screen assembly

300 is disposed in the

second housing

200. The

first housing

100 is rotatable relative to the

second housing

200 between a first position and a second position. When the

first housing

100 is at the first position relative to the

second housing

200, the display surfaces of the

screen assemblies

300 are located on the same plane, and the electronic device is unfolded, that is, the electronic device is in an unfolded state. In a case where the

first casing

100 is in the second position with respect to the

second casing

200, the

first casing

100 and the

second casing

200 are folded with each other, that is, the electronic apparatus is in a folded state. In an alternative embodiment, the electronic device is a fold-out electronic device, that is, when the

first casing

100 is in the second position relative to the

second casing

200, a side of the

first casing

100 away from the

screen assembly

300 is overlapped with a side of the

second casing

200 away from the

screen assembly

300, so as to fold out the electronic device. In another alternative embodiment, the electronic device is a foldable electronic device, that is, in a case that the

first casing

100 is at the second position relative to the

second casing

200, a side of the

first casing

100 close to the

screen assembly

300 is overlapped with a side of the

second casing

200 close to the

screen assembly

300, so as to realize the inward folding of the electronic device.

The first section of the

screen assembly

300 is slidably engaged with the

first housing

100 such that the first section of the

screen assembly

300 can slide along the

first housing

100. Both ends of the

first link mechanism

600 are respectively connected to the

slider

500 and the first segment of the

screen assembly

300, so that the

slider

500 can drive the first segment of the

screen assembly

300 to slide relative to the

first casing

100 through the

first link mechanism

600. Illustratively, during the folding process of the electronic device, the

first housing

100 and/or the

second housing

200 drives the

shaft assembly

400 to rotate relative to the

slider

500. The

shaft assembly

400 carries the

slider

500 along the

shaft assembly

400. The

slider

500 drives the first segment of the

screen assembly

300 to move toward or away from the second segment of the

screen assembly

300 through the

first link mechanism

600.

Note that, the electronic device folding-out described in the present specification means: when the electronic device is in the folded state, the

screen assembly

300 is located on one side of the

first casing

100 and the

second casing

200 close to the outer surface, that is, a first section of the

screen assembly

300 is disposed on one side of the

first casing

100 facing away from the

second casing

200, and a second section of the

screen assembly

300 is disposed on one side of the

second casing

200 facing away from the

first casing

100. Therefore, in case the electronic device is folded outward, the display can still be performed through the

screen assembly

300.

The electronic device described in the specification of the present application is folded inward: in the folded state of the electronic device, the

screen assembly

300 is located on the side of the

first casing

100 and the

second casing

200 away from the outer surface, that is, a first section of the

screen assembly

300 is disposed on the side of the

first casing

100 close to the

second casing

200, and a second section of the

screen assembly

300 is disposed on the side of the

second casing

200 close to the

first casing

100. Accordingly, in case of the electronic device being folded inward, the

protection screen assembly

300 may be folded by the electronic device.

Electronic equipment is at the in-process of rolling over outward,

first casing

100 is to keeping away from relatively

second casing

200 one side of

screen subassembly

300 is rotated, and

first link mechanism

600 drives first section in the

screen subassembly

300 and moves to the second section that is close to

screen subassembly

300, and then avoids electronic equipment to receive at the in-

process screen subassembly

300 of rolling over outward and drags, solves

screen subassembly

300 and receives easily at the in-process of electronic equipment rolling over outward and drags and the problem of damage.

In the process of folding the electronic device inwards, that is, the

first casing

100 is close to the

second casing

200, one side of the

screen assembly

300 is rotated, the

first link mechanism

600 drives the first section of the

screen assembly

300 to move towards the second section far away from the

screen assembly

300, so that the first section and the second section of the

screen assembly

300 are prevented from being extruded with each other in the process of folding the electronic device inwards, and the problem that the

screen assembly

300 is easily extruded and damaged in the process of folding the electronic device inwards is solved.

Therefore, the above-mentioned solution can prevent the

screen assembly

300 from being pulled or pressed during the folding process of the electronic device, thereby achieving the purpose of protecting the screen assembly. In addition, during use of the electronic device, the

screen assembly

300 may be subjected to forces in various directions, such as: friction generated by the finger during sliding on the surface of the

screen assembly

300. The above-mentioned embodiment can increase the resistance of the

screen assembly

300 to move the

first link mechanism

600 by the transmission of the

bevel gear

410 and the

first tooth structure

510. Therefore, the electronic device according to the above embodiment can prevent the first section of the

screen assembly

300 from sliding relative to the

first casing

100 in the unfolded state. Therefore, the electronic device described in the above embodiment does not need to add a damping structure for preventing the

screen assembly

300 from sliding with respect to the

first casing

100.

Referring to fig. 3 to 6, the

shaft assembly

400 includes a first

rotating shaft

420, a second

rotating shaft

430, and a

bracket

440. The first

rotating shaft

420 and the second

rotating shaft

430 are disposed in parallel on the

bracket

440, and both the first

rotating shaft

420 and the second

rotating shaft

430 are rotatably engaged with the

bracket

440. The first

rotating shaft

420 is connected to the

first casing

100, and the

first casing

100 can drive the first

rotating shaft

420 to rotate. The

second shaft

430 is connected to the

second housing

200, and the

second housing

200 can drive the

second shaft

430 to rotate.

In an alternative embodiment, the first

rotating shaft

420 and the

first casing

100 may be fixedly connected, so that the

first casing

100 can drive the first

rotating shaft

420 to rotate. Of course, the first

rotating shaft

420 and the

first casing

100 may be detachably connected, and the first

rotating shaft

420 and the

first casing

100 may be rotationally limited. Illustratively, for example, one of the first

rotating shaft

420 and the

first casing

100 is provided with a limiting groove, the other is provided with a limiting protrusion, and the limiting protrusion is at least partially located in the limiting groove, so that the

first casing

100 can drive the first

rotating shaft

420 to rotate. For this reason, the present embodiment does not limit the connection manner between the

first casing

100 and the first

rotating shaft

420. Similarly, the

second housing

200 and the second

rotating shaft

430 may be coupled in the same manner as the

first housing

100 and the first

rotating shaft

420. Therefore, the connection manner between the

second housing

200 and the second

rotating shaft

430 will not be further described in this specification.

In the above embodiment, the first

rotating shaft

420 and the second

rotating shaft

430 are arranged in parallel, so that the

first casing

100 and the

second casing

200 respectively rotate around two parallel axes, and a space for the

first casing

100 and the

second casing

200 to escape from each other is increased, so as to prevent the

first casing

100 and the

second casing

200 from interfering with each other during the process of unfolding or folding the electronic device. Further, the interval between the first and second

rotating shafts

420 and 430 may be adjusted according to the thicknesses of the first and

second housings

100 and 200. Specifically, the larger the distance between the first

rotating shaft

420 and the second

rotating shaft

430 is, the larger the space formed by the

first housing

100 and the

second housing

200 at the

shaft assembly

400 to escape from each other is. Further, it is necessary to select a distance between the first

rotating shaft

420 and the second

rotating shaft

430 according to thicknesses of the

first housing

100 and the

second housing

200. For this reason, the embodiment does not limit the interval between the first

rotating shaft

420 and the second

rotating shaft

430.

In an alternative embodiment, the first

rotating shaft

420 and the second

rotating shaft

430 are spaced apart by a first distance, and the first

rotating shaft

420 is spaced apart from a side of the first section of the

first casing

100 away from the

screen assembly

300 by a second distance. The second

rotating shaft

430 is spaced a third distance from a side of the

second housing

200 away from the second section of the

screen assembly

300. First distance is not less than second distance and third distance sum, and then under the circumstances of the electronic equipment infolding,

first casing

100 and

second casing

200 can laminate better to reduce the thickness after the electronic equipment coincide, improve the comfort level after the electronic equipment folding.

Referring to fig. 4, 5 and 13, the

shaft assembly

400 further includes a

first support plate

screen assembly

300, so as to provide a supporting force for the

screen assembly

300 at a joint of the

first casing

100 and the

second casing

200 through the

first support plate

450, and prevent the

screen assembly

300 at the joint of the

first casing

100 and the

second casing

200 from being depressed due to a force. Illustratively, the

first support plate

450 has a circular arc shape, and the corresponding axis of the

first support plate

450 coincides with the axis of the

first casing

100 rotating relative to the

second casing

200, so that the

screen assembly

300 can better fit with the

first support plate

450 when the electronic device is in the folded state.

In an alternative embodiment, the

first support plate

450 may be fixedly disposed on the

bracket

440. Illustratively, the

first support plate

450 may be fixed with the

bracket

440 by screws. Of course, the

first support plate

450 and the

bracket

440 may be provided as an integral structure.

500. Also, the

slider

500 may improve the stability of the first and second

rotating shafts

420 and 430. The

first casing

100 and the

second casing

200 may be subjected to a force of separating from each other during use of the electronic apparatus, for example, an operator may hold only the

first casing

100 or the

second casing

200 of the electronic apparatus during use of the electronic apparatus. Therefore, the first and second

rotating shafts

420 and 430 may be subjected to a force separating from or approaching each other. The above scheme can limit the distance between the first

rotating shaft

420 and the second

rotating shaft

430 through the

slider

500, thereby improving the stability of the first

rotating shaft

420 and the second

rotating shaft

430.

In an alternative embodiment, the

first link mechanism

600 includes a

first link

610, a first end of the

first link

screen assembly

300.

Referring to fig. 4 to 6, during the movement of the

slider

500 along the axial direction of the

shaft assembly

400, the angle between the

first link

610 and the

shaft assembly

400 increases or decreases, and thus the first segment of the

screen assembly

300 can be pulled to move along the

first casing

100. There are many ways in which the first end of the

first link

610 is rotatably coupled to the

slider

500, for example, the first end of the

first link

610 and the

slider

500 may be coupled by a universal joint. There are many types of universal joints, for example: cross-pin type rigid universal joints, ball-and-fork type universal joints, flexible universal joints, ball-and-socket type universal joints, etc. For this reason, the present application does not limit the specific manner in which the first end of the

slider

500 along the

shaft assembly

400, the

first link

610 may rotate with the

first protrusion

110 as a supporting point and slide relative to the

first protrusion

110. Referring to fig. 4, as the angle between the

first link

610 and the

shaft assembly

400 is gradually decreased, the

slider

500 has a greater resistance to the movement of the first segment of the

screen assembly

300 via the

first link

610. It should be noted that the included angle between the

first link

610 and the

shaft assembly

400 in the embodiment of the present application is an included angle formed between the

first link

610 and the

shaft assembly

400, which is smaller than or equal to 90 °. In this embodiment, by providing the

first protrusion

110, when the included angle between the

first link

610 and the

shaft assembly

400 is gradually decreased, the length between the

first protrusion

110 and the

slider

500 in the

first link

610 is increased, so as to reduce the resistance of the

slider

500 to the movement of the

block

500, and the

hinge

620 is rotatably engaged with the first

rotating shaft

420, so that the

hinge

620 can be rotatably engaged with the sliding

block

500 through the first

rotating shaft

420.
