Wherein the display panel is a foldable flexible display panel.

The hinge assembly of the embodiments of the present disclosure is described below.

As shown in fig. 1 to 4, the hinge assembly 100 of the embodiment of the present disclosure includes a bracket 1, a moving member 2, a first movable member 31, and a second movable member 32.

The moving member 2 is provided movably in a first direction (up-down direction as shown in fig. 1) on the bracket 1. Each of the first movable member 31 and the second movable member 32 is swingably provided on the bracket 1, the swing axis of the first movable member 31 and the swing axis of the second movable member 32 each extend in a first direction (up-down direction as shown in fig. 1), the first movable member 31 and the second movable member 32 each are movably connected to the movable member 2, and the movable member 2 is configured to drive the first movable member 31 and the second movable member 32 to swing simultaneously by moving in the first direction (up-down direction as shown in fig. 1).

The first movable member 31 is for connection with a first housing of the terminal device, and the second movable member 32 is for connection with a second housing of the terminal device, such that each of the first housing and the second housing is swingable with respect to the bracket 1. When the first housing swings, the first movable member 31 swings with the first housing, and when the second housing swings, the second movable member 32 swings with the second housing; similarly, when the first movable member 31 swings, the first housing swings with the first movable member 31, and when the second movable member 32 swings, the second housing swings with the second movable member 32.

The first movable member 31 and the second movable member 32 are movably connected with the movable member 2, and the movable member 2 moves along the first direction (up-down direction shown in fig. 1), so that the first movable member 31 and the second movable member 32 can be driven to swing simultaneously. For example, when the first movable member 31 swings, the movable member 2 is driven to move up and down, and the second movable member 32 is driven to swing by the movable member 2, so that the first movable member 31 and the second movable member 32 swing simultaneously; when the second movable piece 32 swings, the movable piece 2 is driven to move up and down, and the movable piece 2 is used for driving the first movable piece 31 to swing, so that the first movable piece 31 and the second movable piece 32 swing simultaneously. Thereby achieving simultaneous swinging of the first housing connected to the first movable member 31 and the second housing connected to the second movable member 32.

The moving member 2 of the hinge assembly 100 of the embodiment of the present disclosure only needs to be able to move in the first direction, and the swing of the first movable member 31 is converted into the movement of the moving member 2 in the first direction, and the movement of the moving member 2 in the first direction is converted into the swing of the second movable member 32. In short, the hinge assembly 100 of the embodiment of the present disclosure achieves synchronous swinging of the first movable member 31 and the second movable member 32 by movement of the movable member 2, and can greatly reduce the size of the movable member 2 in the third direction (front-rear direction shown in fig. 1) compared to the simultaneous swinging of the first movable member 31 and the second movable member 32 by a gear structure in the related art, so that the overall thickness of the hinge assembly 100 can be reduced, facilitating the slim design of a terminal device having the hinge assembly 100. Wherein the third direction is perpendicular to the first direction.

Accordingly, the hinge assembly 100 of the embodiment of the present disclosure has advantages of thin thickness and the like.

The terminal device having the hinge assembly 100 of the embodiment of the present disclosure has advantages of thin thickness and the like.

Alternatively, the first and second movable members 31 and 32 each have a support surface for supporting the display panel of the terminal device when the terminal device having the hinge assembly 100 is in the unfolded state. For example, the display panel includes a first portion and a second portion, the support surface of the first movable member 31 is for supporting the first portion, and the support surface of the second movable member 32 is for supporting the second portion. When the terminal device is folded, the display panel is located in a space formed by the first movable member 31, the second movable member 32, and the stand 1.

In order to make the technical solution of the present application easier to understand, the technical solution of the present application will be further described below by taking the example that the first direction coincides with the up-down direction, the example that the second direction coincides with the left-right direction, and the example that the third direction coincides with the front-rear direction, wherein the up-down direction, the left-right direction, and the front-rear direction are as shown in fig. 1.

For example, the mover 2 may move in the up-down direction on the bracket 1. The first movable member 31 and the second movable member 32 are each swingably connected to the bracket 1, and the swing axis of the first movable member 31 and the swing axis of the second movable member 32 extend in the up-down direction. The first movable member 31 and the second movable member 32 are disposed at intervals in the left-right direction, for example, the first movable member 31 is located on the left side of the second movable member 32. The first movable member 31 and the second movable member 32 are swingable in the front-rear direction, and the first movable member 31 and the second movable member 32 are movably connected with the movable member 2.

The hinge assembly 100 moves from the folded state to the unfolded state. Under the action of the first movable member 31, the second movable member 32 and the movable member 2, the first housing and the second housing are simultaneously swung rearward in opposite directions, eventually fully expanding the display panel and the apparatus housing.

In the process of moving the hinge assembly 100 from the unfolded state to the folded state, the first and second housings swing forward in opposite directions simultaneously under the action of the first and second movable members 31 and 32 and the movable member 2, and finally the display panel and the device housing are folded.

In some embodiments, the moving member 2 has a first guide portion 21, and the first movable member 31 has a second guide portion 311, and the first guide portion 21 is movably engaged with the second guide portion 311 in a first direction (up-down direction as shown in fig. 1).

The moving member 2 has a third guide portion 22, and the second moving member 32 has a fourth guide portion 321, and the third guide portion 22 is movably engaged with the fourth guide portion 321 in the first direction (up-down direction as shown in fig. 1).

For example, as shown in fig. 1, the first guide portion 21 and the second guide portion 311 cooperate with each other, so that the first movable member 31 can drive the movable member 2 to move when swinging, or can drive the first movable member 31 to swing when the movable member 2 moves.

The third guide 22 and the fourth guide 321 are engaged with each other. Thus, the second movable member 32 may drive the movable member 2 to move when swinging, or the movable member 2 may drive the second movable member 32 to swing when moving.

When the first movable piece 31 swings, the movable piece 2 can be driven to move, so that the second movable piece 32 is driven to swing; or, when the second movable member 32 swings, the movable member 2 may be driven to move, so as to drive the first movable member 31 to swing.

Thus, the movement of the moving member 2 can be guided by the cooperation of the first guide portion 21 and the second guide portion 311 and the cooperation of the third guide portion 22 and the fourth guide portion 321, so that the moving member 2 moves along a predetermined path parallel to the first direction, which is beneficial to improving the reliability of the hinge assembly 100.

In some embodiments, one of the first guide portion 21 and the second guide portion 311 is a first arc-shaped protrusion extending in a first direction (up-down direction as shown in fig. 1), and the other of the first guide portion 21 and the second guide portion 311 is a first arc-shaped chute extending in the first direction (up-down direction as shown in fig. 1).

The projection of the outer peripheral contour of the first guide portion 21 and the outer peripheral contour of the second guide portion 311 on a plane perpendicular to the front-rear direction is curved. For example, as shown in fig. 1, the first guide portion 21 is a first arc-shaped protrusion, and the second guide portion 311 is a first arc-shaped chute, and the first arc-shaped protrusion is movably disposed in the first arc-shaped chute along the up-down direction. Wherein the first arcuate projection has first and second ends opposite in a first direction, the first and second ends being disposed along a second direction.

Through the cooperation of the first arc-shaped bulge and the first arc-shaped chute, the first movable piece 31 can drive the movable piece 2 to move during swinging, or can drive the first movable piece 31 to swing during moving of the movable piece 2. Thus, the first guide portion 21 and the second guide portion 311 have a simple structure, and are easy to manufacture.

In some embodiments, one of the fourth guide 321 of the third guide 22 is a second arc-shaped protrusion extending in the first direction (up-down direction as shown in fig. 1), and the other of the third guide 22 and the fourth guide 321 is a second arc-shaped chute extending in the first direction (up-down direction as shown in fig. 1).

The projection of the outer peripheral outline of the third guide portion 22 and the outer peripheral outline of the fourth guide portion 321 on a plane perpendicular to the front-rear direction is curved. For example, as shown in fig. 1, the third guiding portion 22 is a second arc-shaped protrusion, the fourth guiding portion 321 is a second arc-shaped chute that mates with the second arc-shaped protrusion, and the second arc-shaped protrusion is movably disposed in the second arc-shaped chute along the up-down direction. Wherein the second arcuate projection has first and second ends opposite in the first direction, the first and second ends being disposed along the second direction.

Through the cooperation of the second arc-shaped protrusion and the second arc-shaped chute, the second movable piece 32 can drive the movable piece 2 to move during swinging, or can drive the second movable piece 32 to swing during moving of the movable piece 2. Thus, the third guide portion 22 and the fourth guide portion 321 have a simple structure, and are easy to manufacture.

In some embodiments, the first movable member 31 and the second movable member 32 are arranged along a second direction (a left-right direction as viewed in fig. 1), the first movable member 31 and the second movable member 32 are located on the same side of the movable member 2 in a third direction, the second direction is perpendicular to the first direction (an up-down direction as viewed in fig. 1), and the third direction is perpendicular to each of the second direction and the first direction.

For example, as shown in fig. 1 to 3, the first movable member 31 is provided on the left side of the second movable member 32, and both the first movable member 31 and the second movable member 32 are provided on the front side of the movable member 2.

Thus, the first movable member 31 and the second movable member 32 do not overlap in the front-rear direction (thickness direction of the hinge assembly 100), which is advantageous for further reducing the thickness of the hinge assembly 100 and further for the slim design of the terminal device having the hinge assembly 100.

In some embodiments, the stent 1 has a first relief portion 11 and the displacement member 2 is disposed within the first relief portion 11.

For example, as shown in fig. 4, the first relief portion 11 may be a groove, and the shape of the first relief portion 11 is adapted to the shape of the moving member 2, and the moving member 2 may be embedded in the first relief portion 11. In the first direction, the size of the first escape portion 11 is larger than the size of the movable member 2 so that the movable member 2 can move in the first direction within the first escape portion 11.

Thus, at least a portion of the moving member 2 is located in the bracket 1 in the front-rear direction, which is advantageous in further reducing the thickness of the hinge assembly 100 and further in the light and slim design of the terminal device having the hinge assembly 100.

In some embodiments, the first guide portion 21 and the third guide portion 22 are disposed at intervals along the first direction (up-down direction as shown in fig. 1).

For example, as shown in fig. 1, the first guide portion 21 is above the third guide portion 22. Namely, the first guide portion 21 and the third guide portion 22 are arranged offset in the up-down direction.

Thus, while ensuring that the moving member 2 has sufficient structural strength, the size of the moving member 2 in the second direction can be effectively reduced, so that the overall structure of the hinge assembly 100 is more compact, and the slim design of the terminal device having the hinge assembly 100 is utilized.

In some embodiments, the moving member 2 has a fifth guide 23, and the bracket 1 has a sixth guide, with which the fifth guide 23 slidably engages in a first direction (up-down direction as shown in fig. 1).

Specifically, the fifth guiding portion 23 and the sixth guiding portion are connected and can slide relatively, and there are many structures of the fifth guiding portion 23 and the sixth guiding portion, for example, the fifth guiding portion 23 and the sixth guiding portion are in a snap fit or hook fit, so as to realize connection of the fifth connecting portion and the sixth connecting portion; and the fifth guide 23 and the sixth guide extend in the up-down direction so that the fifth guide 23 and the sixth guide slide relatively in the up-down direction.

Thus, the movement of the moving member 2 can be guided by the cooperation of the fifth guide portion 23 and the sixth guide portion, so that the moving member 2 moves along a predetermined path parallel to the first direction, which is advantageous for improving the reliability of the hinge assembly 100.

In some embodiments, the fifth guide portion 23 is provided in plurality, the sixth guide portion is provided in plurality, the plurality of fifth guide portions 23 are in one-to-one correspondence with the plurality of sixth guide portions, and each fifth guide portion 23 is engaged with the corresponding sixth guide portion.

For example, as shown in fig. 1, the moving member 2 has two fifth guiding portions 23, and the bracket 1 has two sixth guiding portions, where each fifth guiding portion 23 may be engaged with a corresponding sixth guiding portion.

Therefore, the plurality of fifth guide parts 23 are matched with the plurality of sixth guide parts, so that the moving part 2 moves more stably, and the stability of the hinge assembly 100 is improved.

It is understood that the fifth guide 23 and the sixth guide may be 3, 4, etc.

Of course, in other embodiments, one fifth guide portion 23 and one sixth guide portion may be provided.

In some embodiments, the plurality of fifth guides 23 are disposed at intervals along the second direction (left-right direction as shown in fig. 1).

For example, as shown in fig. 1, the moving member 2 is provided with a fifth guide portion 23 on each of the left and right sides, so that the left and right sides of the moving member 2 can slide smoothly, and the plurality of fifth guide portions 23 can ensure that the moving member 2 has sufficient structural strength, thereby being beneficial to improving the stability of the hinge assembly 100.

In some embodiments, one of the fifth guide 23 and the sixth guide is a third arc-shaped protrusion extending in the first direction (up-down direction as shown in fig. 1), and the other of the fifth guide 23 and the sixth guide is a third arc-shaped chute extending in the first direction (up-down direction as shown in fig. 1).

The projection of the outer peripheral outline of the fifth guide portion 23 and the outer peripheral outline of the sixth guide portion on a plane perpendicular to the up-down direction is arc-shaped. For example, the third arc-shaped protrusion is movably provided in the third arc-shaped chute in the up-down direction.

Thus, the fifth guide portion 23 and the sixth guide portion have a simple structure, and are easy to manufacture. In some embodiments, the bracket 1 has a first mating portion 13, the first movable member 31 has a second mating portion 312, and the second mating portion 312 is rotatably mated with the first mating portion 13 along the swing axis of the first movable member 31.

The first engaging portion 13 and the second engaging portion 312 may have various structures, for example, the first engaging portion 13 is a rotation shaft, and the second engaging portion 312 is a hole. Alternatively, the first mating portion 13 is an arc-shaped protrusion, the second mating portion 312 is an arc-shaped chute, and the first mating portion 13 is movably disposed in the second mating portion 312.

Thus, by the engagement of the first engagement portion 13 and the second engagement portion 312, the swinging of the first movable member 31 can be guided, so that the first movable member 31 can swing with respect to the movable member 2, which is advantageous in improving the reliability of the hinge assembly 100.

In some embodiments, the bracket 1 has a third mating portion 14, the second movable member 32 has a fourth mating portion 322, and the fourth mating portion 322 is rotatably mated with the second mating portion 312 along the swing axis of the second movable member 32.

The third mating portion 14 and the fourth mating portion 322 may have a variety of structures, for example, the third mating portion 14 is a rotating shaft, and the fourth mating portion 322 is a hole. Alternatively, the third mating portion 14 is an arc-shaped protrusion, and the fourth mating portion 322 is an arc-shaped chute. The third mating portion 14 is movably disposed within the fourth mating portion 322.

Thus, by the engagement of the third engaging portion 14 and the fourth engaging portion 322, the swinging of the second movable member 32 can be guided, so that the second movable member 32 can swing with respect to the movable member 2, which is advantageous in improving the reliability of the hinge assembly 100.

In some embodiments, one of the first mating portion 13 and the second mating portion 312 is a fourth arcuate projection extending in the second direction (left-right direction as shown in fig. 1), and the other of the first mating portion 13 and the second mating portion 312 is a fourth arcuate runner extending in the second direction (left-right direction as shown in fig. 1).

For example, as shown in fig. 1, the fourth arc-shaped protrusion and the fourth arc-shaped chute extend along the left-right direction, the first mating portion 13 is the fourth arc-shaped protrusion, the second mating portion 312 is the fourth arc-shaped chute, or the first mating portion 13 is the fourth arc-shaped chute, and the second mating portion 312 is the fourth arc-shaped protrusion. The fourth arc-shaped bulge is movably arranged in the fourth arc-shaped chute along the left-right direction.

Therefore, the first movable piece 31 can swing smoothly relative to the bracket 1 by utilizing the fourth arc-shaped bulge and the fourth arc-shaped chute, and the fourth arc-shaped bulge and the fourth arc-shaped chute are simple in structure and convenient to process and manufacture.

In some embodiments, one of the third mating portion 14 and the fourth mating portion 322 is a fifth arcuate projection extending in the second direction (left-right direction as shown in fig. 1), and the other of the third mating portion 14 and the fourth mating portion 322 is a fifth arcuate runner extending in the second direction (left-right direction as shown in fig. 1).

For example, as shown in fig. 1, the fifth arc protrusion and the fifth arc chute extend along the left-right direction, the third mating portion 14 is the fifth arc protrusion, the fourth mating portion 322 is the fifth arc chute, or the third mating portion 14 is the fifth arc chute, and the fourth mating portion 322 is the fifth arc protrusion. The fifth arc-shaped bulge is movably arranged in the fifth arc-shaped chute along the left-right direction.

Therefore, the second movable piece 32 can swing smoothly relative to the bracket 1 by utilizing the fifth arc-shaped bulge and the fifth arc-shaped chute, and the fifth arc-shaped bulge and the fifth arc-shaped chute have simple structures and are convenient to process and manufacture.

In some embodiments, the second guide portion 311 and the second engaging portion 312 are disposed at intervals along the first direction (up-down direction as shown in fig. 1).

For example, the second guide portion 311 and the second mating portion 312 are arranged in the up-down direction, that is, the second guide portion 311 and the second mating portion 312 are arranged in the direction perpendicular to the front-rear direction, thereby facilitating the reduction of the size of the first movable member 31 in the front-rear direction, making the overall structure of the hinge assembly 100 more compact, and facilitating the light and slim design of the terminal device.

In some embodiments, the fourth guide portion 321 and the fourth mating portion 322 are disposed at intervals along the first direction (up-down direction as shown in fig. 1).
