[0002] Resin prism sheets are lenses with a resin layer and are an important component accounting for about 37% of the raw material cost of LCD backlight modules. They are also light-concentrating devices, mainly using the laws of total internal reflection and refraction to concentrate scattered light into a certain angle range, thereby increasing the brightness within that range.

[0003] In the prior art, a prism sheet for a backlight module is disclosed in the utility model patent with authorization announcement number CN217425886U. In this prism sheet, a support assembly consisting of a suction cup, a rotating cylinder and a lead screw is installed between the diffuser sheet and the fixing plate, which can support the diffuser sheet and adjust its position at the same time.

[0004] However, in actual use, it was found that the diffuser plate has four sets of support components consisting of suction cups, rotating cylinders and lead screws. During adjustment, it is necessary to ensure that the adjustment of the four sets of support components is consistent, and each support component needs to be adjusted individually. This makes the operation of adjusting the installation position of the diffuser plate difficult and cannot meet the usage requirements. Therefore, a resin prism sheet is proposed.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-3 The resin prism sheet shown includes a resin prism sheet body 100, a support assembly 300, and an adjustment mechanism 400. The structure of the resin prism sheet body 100 can be referenced from a prism sheet for a backlight module disclosed in utility model patent CN217425886U. A diffuser 200 is provided above the resin prism sheet body 100. A fixing plate is symmetrically fixed to the side of the resin prism sheet body 100 near the diffuser 200. The support assembly 300 is installed at the end between the fixing plate and the diffuser 200. The adjustment mechanism 400 is provided with… The adjustment mechanism 400 is placed between two adjacent support components 300 and is used to adjust the length of the support component 300. By adding the adjustment mechanism 400 between two support components 300 on the same fixed plate, the length of the two support components 300 can be adjusted synchronously. In this way, when adjusting the installation position of the diffuser 200, only two adjustment mechanisms 400 are needed to adjust all four support components 300. This makes the adjustment of the installation position of the diffuser 200 more convenient, easier to operate, more suitable for manual operation, more efficient, and better meets the actual use needs.

[0023] The support assembly 300 includes a hollow sleeve 301 and a support column 302. The bottom end of the hollow sleeve 301 is fixedly connected to a fixed plate, and the support column 302 is slidably connected to the hollow sleeve 301. The top end of the hollow sleeve 301 has a downwardly recessed telescopic cavity 303, the top surface of which is convex. The outer wall of the support column 302 is slidably connected to the inner side of the telescopic cavity 303. The convex-shaped telescopic cavity 303 can limit and guide the support column 302 within the hollow sleeve 301, making the lifting and lowering process of the support column 302 more stable. The outer wall of the support column 302 has a scale strip 305. Since the outer wall of the support column 302 is vertical, Furthermore, there is no rotation during the lifting process. Therefore, a scale strip 305 is provided on the outer wall of the support column 302, which allows the distance of the support column 302 to be known during the lifting process. This allows the support components 300 at both sides of the bottom of the diffuser 200 to observe whether the adjustment distance is consistent through the scale strip 305, thereby improving the adjustment accuracy. A suction cup 304 is fixedly connected to the top of the support column 302. The support column 302 is fixedly connected to the diffuser 200 through the suction cup 304. The suction cup 304 can form an adsorption fixation with the diffuser 200, which facilitates the installation and removal of the diffuser 200 from the support component 300.

[0024] Furthermore, the adjusting mechanism 400 includes a handle 405, with one-way screws 404 fixedly connected to both ends of the handle 405. An inner threaded sleeve 401 is threaded onto the outer wall of each of the two one-way screws 404. A movable claw is provided at the end of the inner threaded sleeve 401 away from the one-way screw 404. The inner threaded sleeve 401 is hinged to the hollow sleeve 301 and the support column 302 respectively via the movable claw. The handle 405 allows the operator to manually rotate the two one-way screws 404, causing the inner threaded sleeve 401 to move axially along the one-way screw 404 while the one-way screw 404 rotates. Combined with the connecting action of the movable claw, the inner threaded sleeve 401 can move while simultaneously driving the support column 302 in the support assembly 300 to move upwards or downwards via the movable claw.

[0025] In a preferred embodiment, the movable claw includes a hinge seat 402 and two hinge rods 403. The two hinge rods 403 are rotatably connected to both ends of the hinge seat 402, and the other ends of the two hinge rods 403 are rotatably connected to the hollow sleeve 301 and the sidewall of the support column 302, respectively. The sidewall of the hinge seat 402 is fixedly connected to one end of the internal threaded sleeve 401. The end of the hinge rod 403 located at the bottom of the hinge seat 402 is rotatably connected to the bottom of the telescopic cavity 303, and the end of the hinge rod 403 located at the top of the hinge seat 402 is rotatably connected to the top of the sidewall of the support column 302. When the internal threaded sleeve 401 moves axially along the one-way screw 404, it can drive the hinge seat 402 to move. As the hinge seat 402 moves, the two hinge rods 403 will rotate and open or close. The two hinge rods 403 are retracted, thereby increasing or decreasing the distance between the ends of the two hinge rods 403 away from the hinge seat 402. Since the ends of the two hinge rods 403 are rotatably connected to the support column 302 and the hollow sleeve 301 in the support assembly 300, the ends of the hinge rods 403 can move while driving the support column 302 to move along the vertical direction of the hollow sleeve 301. This allows for adjustment of the telescopic length of the support assembly 300. Moreover, the two support assemblies 300 on each fixed plate can be adjusted through only one adjustment mechanism 400, which is simple and convenient to operate, has high adjustment accuracy, and provides greater stability in the adjustment process of the diffuser 200. It also requires less skill from the operator, thus better meeting the needs of actual use.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
