Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display module technology, and more specifically, to an FPC board and an LCM module. Background Technology

[0002] FPC board, or flexible printed circuit board, is a type of printed circuit board made with polyimide or polyester film as the substrate. It is highly reliable and extremely flexible. LCM module, or liquid crystal display module, is an assembly that combines liquid crystal display devices, connectors, peripheral circuits such as control and drive circuits, PCB circuit boards, backlights, and structural components. FPC board and LCM module are closely related. FPC board, with its excellent electrical connection performance and flexibility, can flexibly lay out wiring in a limited space, building a bridge for signal transmission and circuit connection for electronic components. The core mission of LCM module is to convert electrical signals into visual information and provide users with intuitive display. However, its normal operation depends on stable signal input and power supply. With the continuous development of electronic devices towards miniaturization, thinness, and high performance, the fixing and buffering structures of traditional FPC board and LCM module have exposed some problems.

[0003] A search revealed a Chinese patent application, CN202020756613.9, which discloses an anti-collision LCM liquid crystal display module. The module includes a display module body and an outer frame located outside the display module body. At each of the four corners of the display module body, universal buffers connected to the outer frame are provided for buffering and shock absorption in any direction. This distinguishes it from existing technologies. Furthermore, in real-time use, the universal buffers ensure buffering and shock absorption in any direction for the display module body, effectively improving its ability to buffer and prevent corner chipping when impacted, thus providing better and more comprehensive protection against corner chipping.

[0004] Although the aforementioned patent can ensure buffering and shock absorption of the display module body in any direction through the setting of universal buffer components, effectively improving the display module body's ability to buffer and prevent corner breakage when impacted, and can provide better and more comprehensive buffering and corner breakage protection for the display module body, the following shortcomings still exist in use: 1. The right-angle clip structure is fixed and cannot be adapted to display modules of different thicknesses; 2. The universal buffer components occupy a lot of space when installed at the four corners of the display module body, resulting in poor display effect when the display modules are spliced ​​together.

[0005] Therefore, there is an urgent need for an FPC board and LCM module to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an FPC board and an LCM module to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An FPC board and LCM module include an outer frame, wherein uniformly distributed fixing sleeves A are fixedly connected to the outer wall of the outer frame, and universal balls A are rotatably connected to the outer wall of the fixing sleeves A, and the module further includes:

[0009] An anti-impact assembly includes a telescopic rod fixedly connected to the outer wall of a universal ball A, a universal ball B fixedly connected to the end of the telescopic rod away from the universal ball A, a fixed sleeve B rotatably connected to the outer wall of the universal ball B, a strong tension spring sleeved on the outer wall of the telescopic rod, a mounting plate fixedly connected to the outer wall of the fixed sleeve B, and a fixed clamping plate fixedly connected to the outer wall of the mounting plate.

[0010] Adjust the clamping assembly, which is located on the outer wall of the fixed clamping plate.

[0011] As a preferred technical solution of this application, the adjusting clamping assembly includes symmetrically formed grooves on the outer wall of the fixed clamping plate. A slider is slidably connected to the inner wall of the groove. A guide groove is symmetrically distributed on the outer wall of the slider. A guide block is slidably connected to the inner wall of the guide groove. A screw is threadedly connected to the outer wall of the guide block. A rotating rod is fixedly connected to the outer wall of the screw, and the rotating rod is rotatably connected to the fixed clamping plate. A bevel gear is fixedly connected to the outer wall of the rotating rod, and the bevel gears are meshed and connected symmetrically. A knob is fixedly connected to the outer wall of the outer bevel gear.

[0012] As a preferred technical solution of this application, a display module body is provided between the fixed clamping plate and the movable clamping plate.

[0013] As a preferred technical solution of this application, the outer wall of the outer frame is provided with an FPC board mounting groove.

[0014] As a preferred technical solution of this application, the strong tension spring is fixedly connected to the universal ball A, and the end of the strong tension spring away from the universal ball A is fixedly connected to the universal ball B.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By adjusting the clamping components, the distance between the fixed clamping plate and the moving clamping plate can be easily adjusted, thereby adapting to display modules of different thicknesses. This improves the versatility of LCM modules, reduces the trouble of changing different fixing structures due to different display module thicknesses, lowers production costs, and is simple and easy to operate without requiring complex tools or professional skills. It solves the problem of existing right-angle clip structures being unable to adapt to display modules of different thicknesses.

[0018] 2. The shock-resistant components utilize a telescopic rod and omnidirectional ball joint structure, and the display module moves outwards during movement. Compared to traditional omnidirectional buffers installed at the four corners of the display module body, it occupies less space. This allows for smaller gaps between display modules when they are spliced ​​together, thereby improving the overall integrity and continuity of the display and enhancing the display effect. This solves the problem in existing technologies where omnidirectional buffers installed at the four corners of the display module body occupy a large amount of space, resulting in poor display effects when the display modules are spliced ​​together.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1-6As shown, the FPC board and LCM module proposed in this embodiment include an outer frame 1, with uniformly distributed fixing sleeves A3 fixedly connected to the outer wall of the outer frame 1, and universal balls A4 rotatably connected to the outer wall of the fixing sleeves A3. It also includes:

[0029] The shock-resistant assembly includes a telescopic rod 5 fixedly connected to the outer wall of the universal ball A4. A universal ball B7 is fixedly connected to the end of the telescopic rod 5 away from the universal ball A4. A fixed sleeve B8 is rotatably connected to the outer wall of the universal ball B7. A strong tension spring 6 is fitted onto the outer wall of the telescopic rod 5. A mounting plate 9 is fixedly connected to the outer wall of the fixed sleeve B8. A fixed clamping plate 10 is fixedly connected to the outer wall of the mounting plate 9. When the display module body 2 is impacted, the impact force is transmitted to the fixed clamping plate 10. The fixed clamping plate 10, through the mounting plate 9 and the fixed sleeve B8, causes the universal ball B7 to rotate outward. Simultaneously, the telescopic rod 5 extends and retracts. The extension and retraction of the telescopic rod 5 drives the universal ball A4 to rotate. The universal ball A4 and the universal ball B7 rotate at multiple angles to adapt to impact forces from different directions. The strong tension spring 6 fitted onto the outer wall of the telescopic rod 5 undergoes elastic deformation during the extension and retraction of the telescopic rod 5, converting the impact energy into elastic potential energy to offset the impact force. This protects the display module body 2 while increasing the distance between the outer frame 1 and the display module body 2, improving the assembly and usage effect.

[0030] Adjust the clamping assembly, which is located on the outer wall of the fixed clamping plate 10.

[0031] like Figure 4-6 As shown, in a preferred embodiment, based on the above method, the adjusting clamping assembly further includes symmetrically formed grooves 19 on the outer wall of the fixed clamping plate 10. A slider 15 is slidably connected to the inner wall of the groove 19. Symmetrically distributed guide grooves 20 are formed on the outer wall of the slider 15. A guide block 14 is slidably connected to the inner wall of the guide groove 20. A screw 13 is threadedly connected to the outer wall of the guide block 14. A rotating rod 12 is fixedly connected to the outer wall of the screw 13, and the rotating rod 12 is rotatably connected to the fixed clamping plate 10. A bevel gear 16 is fixedly connected to the outer wall of the rotating rod 12, and the symmetrical bevel gears 16 are meshed together. The outer bevel gear 16 is fixedly located on the outer wall. A knob 17 is connected. Rotating the knob 17 causes the outer bevel gear 16 to rotate. The outer bevel gear 16 rotates and, through meshing, drives another bevel gear 16 symmetrical to it to rotate in the opposite direction. The rotation of the bevel gear 16 causes the rotating rod 12 fixed to it to rotate synchronously in the opposite direction. The rotation of the rotating rod 12 drives the screw 13 to rotate. When the screw 13 rotates, the guide block 14 is restricted by the guide groove 20 and can only move along the axial direction of the screw 13. It also presses the guide groove 20 to drive the slider 15 to slide in the slide groove 19, thereby realizing the adjustment of the position of the moving clamp 18 relative to the fixed clamp 10, so as to adapt to the display module body 2 of different thicknesses.

[0032] like Figure 2As shown, in a preferred embodiment, based on the above method, a display module body 2 is further provided between the fixed clamping plate 10 and the movable clamping plate 18, and the display module body 2 is used to display information.

[0033] like Figure 2 As shown, in a preferred embodiment, based on the above method, the outer wall of the outer frame 1 is further provided with an FPC board mounting groove 11, through which the FPC board is mounted and connected to the display module body 2 for use.

[0034] like Figure 3 As shown, in a preferred embodiment, based on the above method, the strong tension spring 6 is further fixedly connected to the universal ball A4, and the end of the strong tension spring 6 away from the universal ball A4 is fixedly connected to the universal ball B7. The display module body 2 is quickly returned to its original position after the impact force is offset by the tension of the strong tension spring 6.

[0035] Specifically, when using this FPC board and LCM module: Rotating knob 17 causes the outer bevel gear 16 to rotate. The rotation of the outer bevel gear 16, through meshing, drives another bevel gear 16 symmetrical to it to rotate in the opposite direction. The rotation of the bevel gear 16 causes the fixed rotating rod 12 to rotate synchronously in the opposite direction. The rotation of the rotating rod 12 drives the screw 13 to rotate. When the screw 13 rotates, the guide block 14 is restricted by the guide groove 20 and can only move along the axial direction of the screw 13, pressing against the guide groove 20 to drive the slider 15 to slide within the slide groove 19. This achieves the adjustment of the position of the moving clamping plate 18 relative to the fixed clamping plate 10, thus adapting to display modules of different thicknesses. Main body 2; When the main body 2 of the display module is impacted, the impact force is transmitted to the fixed clamp 10. The fixed clamp 10, through the mounting plate 9 and the fixed sleeve B8, causes the universal ball B7 to rotate outward. At the same time, the telescopic rod 5 extends and retracts. The extension and retraction of the telescopic rod 5 drives the universal ball A4 to rotate. The universal ball A4 and the universal ball B7 rotate at multiple angles to adapt to the impact force from different directions. The strong tension spring 6 sleeved on the outer wall of the telescopic rod 5 undergoes elastic deformation during the extension and retraction of the telescopic rod 5, converting the impact energy into elastic potential energy, offsetting the impact force, protecting the main body 2 of the display module, and increasing the distance between the outer frame 1 and the main body 2 of the display module, thereby improving the assembly and use effect.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
