[0028] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0029] As Figures 1 - 3 shown, a lens assembly movement structure of a two-color temperature and double-display finger module of the present utility model includes:

[0030] It further includes an array support 6, on which small round holes are arranged in an array, and a small lens 5 is installed in each small round hole; an array lens 4 is fixed on the array support 6, and the position of the array lens 4 corresponds to that of the small lens 5;

[0031] It further includes a movement support 3, on which a linear bearing module is arranged, and the array support 6 is fastened to the movement support 3 through the linear bearing module.

[0032] As Figure 4 shown, the linear bearing module includes a bearing body 8, a bearing rod 7 and a bearing cover 1;

[0033] The bearing body 8 is installed on both sides of the array support 6, and the bearing rod 7 passes through the bearing body 8, and the bearing body 8 is fastened to the movement support 3 through the bearing rod 7;

[0034] The bearing body 8 is fixed by the bearing cover 1, and one side of the bearing cover 1 protrudes to form a mounting position, and a spring plunger 2 is arranged on the mounting position; the spring plunger 2 is connected to the movement structure; by adopting a linear bearing in the present utility model, the bearing body provides resistance and it is not easy to cause the movement part to get stuck; when the head of the spring plunger is stressed, it will contract a certain stroke, which is mainly to facilitate the spring plunger to drive the array support, so that the array support first collides with the edge of the movement support and then stops after compressing the head of the spring plunger, thus preventing the array support from stopping before reaching the edge.

[0035] Among them, the array support 6 is an integral structure, and a bearing groove 10 is arranged on the side of the array support 6 to facilitate the installation of the bearing.

[0036] Among them, there is a collision distance between the edge of the array support 6 and the movement support 3, and bevel edges are arranged on both sides to ensure that the array support 6 tilts slightly during movement and can be reset by the oblique top of the bevel edges on both sides.

[0037] Among them, the movement distance of the bearing body 8 is greater than the movement distance of the array support 6 to ensure optical collimation.

[0038] In addition, the motion bracket 3 is provided with an avoidance groove 11 to prevent the array lens 4 from being broken.

[0039] In addition, the bearing cover 1 is provided with a glue dripping hole 9 to facilitate fastening the bearing.

[0040] In addition, a threaded hole is provided at the protruding end of the bearing cover 1 on one side, and the spring plunger 2 is arranged in the threaded hole.

[0041] Here’s how it works:

[0042] The utility model adopts a linear bearing, and the bearing body provides resistance, which is not easy to cause the moving parts to get stuck; the array bracket is driven to move by the motion structure, and when the column head of the spring plunger is subjected to force, it will shrink a certain stroke, which is mainly convenient for the spring plunger to drive the array bracket, and the array bracket first reaches the collision edge of the moving bracket and then compresses the column head of the spring plunger before stopping, thereby preventing the array bracket from stopping before reaching the edge.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
