Limited by the structure of the gear itself, the radial dimension of the gear is relatively large, resulting in a relatively large thickness of the hinge structure, which is not conducive to the light and thin design of the terminal equipment.

The hinge assembly of the embodiment of the present disclosure is used for a terminal device. The terminal device in the embodiment of the present disclosure further includes a device casing and a display panel. The device casing includes a first casing and a second casing. Both the first casing and the second casing are connected to a hinge assembly. The simultaneous movement of the main body and the second housing, and the folding and unfolding of the display panel, thereby realizing the folding and unfolding of the terminal device. Wherein, the display panel is a foldable flexible display panel.

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

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

The moving part 2 is movably connected to the bracket 1 along a first direction (up-and-down direction as shown in FIG. 1 ). Each of the first movable part 31 and the second movable part 32 is swingably connected to the support 1, and the swing axis of the first movable part 31 and the swing axis of the second movable part 32 are all along the first direction (as shown in Fig. 1 Shown in the up and down direction), the first movable part 31 and the second movable part 32 are both movably connected with the moving part 2, and the moving part 2 is used to link the first moving part by moving along the first direction (the up and down direction as shown in Figure 1). A movable part 31 and a second movable part 32 .

Wherein the support 1 is used to support and install the first movable part 31 and the second movable part 32, the shape of the support 1 is not limited, as long as it can play a supporting role, the shape of the support 1 can be plate-shaped, I-shaped and so on.

It should be noted that the moving part 2 is movably arranged on the bracket 1 along the first direction (the up-and-down direction shown in FIG. 1 ), which can be understood as the moving part 2 moves along the first direction (the up-down direction shown in FIG. Removably connected to the bracket 1. in "Connected to" may refer to specific implementations such as placing, overlapping, embedding, snapping, etc. It should be understood that the implementation of connecting to in the present disclosure is not limited thereto, as long as the connection between the two can be realized; "Swing" should be understood as being able to move within a certain angle range around a preset axis, which is equivalent to rotation.

The first movable part 31 is used to be connected with the first casing of the terminal device, and the second movable part 32 is used to be connected with the second casing of the terminal device, so that each of the first casing and the second casing is opposite Support 1 can swing. When the first housing swings, the first movable part 31 swings with the first housing, and when the second housing swings, the second movable part 32 swings with the second housing; similarly, when the first movable part 31 swings , the first casing swings with the first movable part 31 , and when the second movable part 32 swings, the second casing swings with the second movable part 32 .

Both the first movable part 31 and the second movable part 32 are movably connected with the movable part 2, and the movable part 2 moves along the first direction (the up-and-down direction shown in FIG. 1 ), and the first movable part 31 and the second movable part 32 can be linked. .

The moving part 2 of the hinge assembly 100 in the embodiment of the present disclosure only needs to be able to move along the first direction, and convert the swing of one of the first moving part 31 and the second moving part 32 into the moving part 2 moving along the first direction. The movement of the movable member 2 along the first direction can be transformed into the swing of the other of the first movable member 31 and the second movable member 32 . In short, the hinge assembly 100 of the embodiment of the present disclosure realizes the swing of the first movable member 31 and the second movable member 32 by the movement of the movable member 2, and then realizes the linkage of the two. Compared with the linkage between the first movable member 31 and the second movable member 32, the size of the movable member 2 in the third direction (the front-rear direction shown in FIG. 1 ) can be greatly reduced, so that the overall thickness of the hinge assembly 100 can be reduced, which is beneficial to have The thinner and lighter design of the terminal device of the hinge assembly 100 . Wherein, the third direction is perpendicular to the first direction.

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