Description

Technical Field

[0001] This application relates to the technical field of light guide plate splicing, and in particular to a light guide plate splicing structure and a splicing method thereof. Background Art

[0002] The principle of the side-entry backlight module: The light emitted by the light source enters the light guide plate from at least one side to generate countless total reflection lights. When the total reflection lights encounter the microstructures on the light guide plate, they diffuse in all directions, generating refracted light and scattered light. The refracted light and scattered light destroy the reflection condition and are emitted from the front of the light guide plate, so that the entire light guide plate panel emits uniform and high-brightness light.

[0003] Therefore, the side-entry backlight module is made into a large-size backlight structure by a splicing method. As described in the utility model with the application number CN2016208030387, it includes at least two groups of spliced light guide plate bodies, and the size, shape, and structure of each group of light guide plate bodies are the same. Splicing surfaces are provided on the two end side walls of the light guide plate body. The splicing surface is an inverted L shape. When the splicing surfaces are spliced, a square through hole is formed at the bottom of the splicing part, and an LED light-emitting tube is provided inside the square through hole.

[0004] Generally, after multiple light guide plate bodies are spliced, if the light source corresponding to one of the light guide plate bodies is damaged, it is necessary to disassemble multiple light guide plate bodies to replace it, and it is relatively troublesome to replace the light source. Summary of the Invention

[0005] In order to improve the above problems, this application provides a light guide plate splicing structure and a splicing method thereof.

[0006] In a first aspect, this application provides a light guide plate splicing structure, adopting the following technical solution: A light guide plate splicing structure, comprising: A bottom plate; Light guide plate bodies that are spliced with each other, installed on the bottom plate. Sinking grooves are provided on part of the side walls of the light guide plate bodies, and reflection films are provided on the remaining side walls; A frame for fixing the light guide plate bodies, and the frame is fixedly installed on the bottom plate; A light strip, installed in the sinking groove; A guiding block, installed on one end of the light strip, A positioning block, detachably installed on the frame, and one end of the light strip away from the guiding block is connected to the positioning block; A locking assembly, installed on the bottom plate, for fixing the guiding block.

[0007] By adopting the above technical solution, the light guide plate bodies are spliced together, and the light strips are installed in the give way grooves. The light strips can better cooperate with the light guide plate bodies through the setting of the give way grooves. The guide blocks and positioning blocks are respectively connected to the two ends of the light strip. The positioning blocks are detachably mounted on the frame, and the guide blocks are fixed by the locking assembly, so that the entire light guide plate splicing structure can be stably spliced. If a light strip is damaged, the corresponding positioning block is removed and the locking assembly is unlocked so that the light strip can be removed from the frame. The relative position of the light guide plate body and the base plate remains unchanged, thereby changing the light strip replacement method and improving the light strip replacement efficiency.

[0008] Optionally, the locking assembly includes: A fixing column, fixedly mounted on the bottom plate and located at the intersection of the plurality of light guide plate bodies; The locking ring is annular in structure and is rotatably mounted between the fixed column and the base plate with its central axis as the rotation center. The locking ring corresponds to the guide block one-to-one. The locking ring is provided with a notch, and the guide block is provided with an insertion hole at a portion close to the base plate. When the guide block contacts the fixed column, the locking ring is rotated so that one end of the locking ring is inserted into the insertion hole. A limiting member is installed on the fixing column and is used to limit the rotation of the locking ring.

[0009] By adopting this technical solution, the locking ring is rotatably installed between the fixed column and the base plate, corresponding one-to-one with the guide block. When the guide block and the fixed column are in contact, the locking ring is rotated so that one end is inserted into the guide block's socket. The stopper restricts the locking ring's rotation, thus reliably fixing the guide block and ensuring the stability of the light strip installation.

[0010] Optionally, the fixing column is provided with a first mounting hole for the rotation of the locking ring, and the base plate is provided with a second mounting hole for the rotation of the locking ring, and an opening of the first mounting hole and the second mounting hole faces the external environment; the end surface of the fixing column facing away from the light guide plate body is provided with a third mounting hole, the first mounting hole and the third mounting hole are connected, and the inner wall portion of the third mounting hole is distributed with threads, and the limiting member is a limiting rod, which is threadedly installed in the third mounting hole, and the rod wall of the limiting rod abuts against the locking ring.

[0011] By adopting the above technical solution, the first and second mounting holes provide space for the rotation of the locking ring, so that the locking ring can rotate smoothly to fix the guide block. The third mounting hole and the limit rod design that match the thread can simultaneously limit the locking ring installed on the same fixed column. The third mounting hole and the limit rod design that match the thread facilitate the installation and disassembly of the limit rod. By adjusting the position of the limit rod in the third mounting hole, the rotation of the locking ring can be effectively limited, thereby ensuring the reliability of the lock ring fixing the guide block. At the same time, this structure is easy to manufacture and assemble.

[0012] Optionally, the fixed column includes a main rod and a sub-rod. The main rod is fixedly connected to the bottom plate. The sub-rod is fixedly installed on the main rod. The sub-rods correspond to the guide blocks one by one, and there is a gap between the sub-rods.

[0013] By adopting the above technical solution, the fixation of the main rod and the bottom plate ensures the overall stability. The one-to-one correspondence between the sub-rods and the guide blocks facilitates the precise fixation operation of the guide blocks. The gap between the sub-rods provides space for the installation and operation of other components and also increases the air flow space. Especially when one ends of multiple light belts are all close to the fixed column, it helps the air flow.

[0014] Optionally, the lock ring is of a hollow structure. Through holes are formed in the outer wall of the lock ring. First heat dissipation holes for communicating with the jacks are formed in the guide blocks. Second heat dissipation holes for communicating with the first mounting holes are formed on the sub-rods.

[0015] By adopting the above technical solution, the lock ring is of a hollow structure and through holes are formed in its outer wall. First heat dissipation holes are formed in the guide blocks, and second heat dissipation holes are formed on the sub-rods. These heat dissipation holes communicate with each other, enabling the lock ring to fix the guide blocks while also serving as a circulation channel for internal and external air, effectively improving the heat dissipation performance of the light guide plate splicing structure.

[0016] Optionally, the guide block is of a cylindrical structure, the cross-section of the relief groove is of an arc structure, and the guide block fits on the inner wall of the relief groove.

[0017] By adopting the above technical solution, the cylindrical guide block fits with the relief groove having an arc cross-section. This design makes the movement of the guide block in the relief groove smoother, reduces friction and resistance, facilitates the installation and adjustment of the light belt, and the cylindrical guide block can also fix the two adjacent light guide plate bodies.

[0018] Optionally, the positioning block is provided with a receiving groove. After the positioning block is separated from the frame, the positioning block is rotated, and the light belt is wound and stored in the receiving groove.

[0019] By adopting the above technical solution, when it is necessary to disassemble or store the light belt, the positioning block is separated from the frame and rotated, and the light belt can be wound and stored in the receiving groove, achieving the effect of winding and storing the light belt while pulling it. The positioning block can be rotated at a position close to the frame, and it can also reduce the space occupied when the light belt is disassembled.

[0020] In a second aspect, the present application provides a method for splicing light guide plates, adopting the following technical solution: A light guide plate splicing method adopts the above-mentioned light guide plate splicing structure, splices two light guide plate bodies in sequence, and after the two adjacent light guide plate bodies are aligned, the gaps are connected to each other, pushing the guide block to move along the base plate and the light guide plate body. When the guide block abuts the fixed column, the light strip is installed between the two light guide plate bodies, first fix the guide block, rotate the locking ring, and after one end of the locking ring passes through the guide block, the locking ring is connected to the guide block, the fixed column and the base plate at one time, so that the guide block is fixed on the base plate, and then the positioning block is fixedly installed on the frame, and the light strip is installed in the gap in a stretched state.

[0021] By adopting the above technical solution, the light strip is installed between the two light guide plate bodies by pushing the guide block, and then the guide block is fixed by using the locking assembly, and finally the positioning block is fixed to make the light strip straight, thereby ensuring the stability of the light guide plate splicing structure and the accuracy of the light strip installation, so that the entire light guide plate splicing structure can work normally and emit uniform, high-brightness light. When a light strip is damaged, the corresponding positioning block is removed, the locking assembly is unlocked, and the guide block is released, so that the light strip can be removed from the frame, while the relative position of the light guide plate body and the base plate remains unchanged, thereby facilitating the replacement of the light strip and improving the efficiency of light strip replacement.

[0022] In summary, this application has at least one of the following beneficial effects: 1. When a light strip is damaged, simply remove the corresponding positioning block, unlock the locking assembly, and release the guide block to remove the light strip from the frame. The relative position of the light guide plate body and the base plate remains unchanged, greatly improving the efficiency of light strip replacement and reducing maintenance costs. 2. The locking ring can not only lock the guide block, but also serve as a circulation channel for internal and external air, effectively improving the heat dissipation performance of the light guide plate splicing structure.

Detailed implementation manners

[0025] The following further Figure 1 - further Figure 8 describes the present application in detail with reference to the appended

[0026] In a first aspect, an embodiment of the present application discloses a light guide plate splicing structure.

[0027] Referring to Figure 1 and Figure 2 , a light guide plate splicing structure includes a bottom plate 100, a frame 200, and a light guide plate body 300 and a light strip 400 mounted on the bottom plate 100. The overall structure uses the bottom plate 100 as a basic bearing platform, and each component is installed according to a specific position and connection relationship to realize the splicing of the light guide plate body 300 and the stable installation and convenient replacement of the light strip 400. A reflective film is installed on one side of the bottom plate 100 close to the light guide plate body 300.

[0028] Referring to Figure 2, the light guide plate bodies 300 of the embodiments of the present application are spliced in two rows, and each row of light guide plate bodies 300 is fixedly installed on the bottom plate 100 through the frame 200. The frame 200 is fixedly installed on the bottom plate 100, and the frame 200 plays a role in fixing the light guide plate body 300 to ensure that the light guide plate body 300 maintains a stable position during the splicing process. A relief groove 310 is formed on a part of the side wall of the light guide plate body 300, and a reflective film is provided on the remaining side walls. After the light guide plate bodies 300 are spliced with each other, they are installed on the bottom plate 100. The relief grooves 310 of the two light guide plate bodies 300 are used to accommodate the light strip 400, so that the light strip 400 can be well matched with the light guide plate body 300. The reflective film helps the reflection and propagation of light in the light guide plate body 300, improving the utilization rate of light.

[0029] Referring to Figure 2 and Figure 3 , the light strip 400 is installed on the bottom plate 100 and located in the relief groove 310, and a guide block 500 is installed at one end of the light strip 400. The guide block 500 is a cylindrical structure, and a cutting surface is provided on the side of the guide block 500 close to the bottom plate 100, and the cutting surface is attached to the bottom plate 100. The cross section of the relief groove 310 is an arc-shaped structure, and the guide block 500 is attached to the inner wall of the relief groove 310. This design makes the guide block 500 move more smoothly in the relief groove 310. When the guide block 500 is located between the two light guide plate bodies 300, it can also play a certain fixing effect on the adjacent two light guide plate bodies 300. When the guide block 500 slides a specific distance along the edge of the light guide plate body 300, the light strip 400 is located in the relief groove 310, and a locking component 700 for locking the guide block 500 is installed on the bottom plate 100. A positioning block 600 is installed at the other end of the light strip 400, and the switch of the light strip 400 is also installed on the positioning block 600.

[0030] Referring to Figure 4 , the positioning block 600 is detachably installed on the frame 200. After the guide block 500 is locked, the positioning block 600 is fixed on the frame 200, so that the light strip 400 is in a straight state and located in the relief groove 310. A through groove 210 for the positioning block 600, the light strip 400 and the guide block 500 to detach is formed on the side wall of the frame 200. After the positioning block 600 is inserted into the through groove 210 and contacts the inner wall of the through groove 210, a cover 220 is threadedly connected to the frame 200, and the cover 220 is screwed into the through groove 210 and presses against the positioning block 600, so that the positioning block 600 is fixed in the frame 200.

[0031] The positioning block 600 is provided with a receiving groove 610. When it is necessary to disassemble or store the light strip 400, the positioning block 600 is detached from the frame 200 and rotated, and the light strip 400 can be wound and stored in the receiving groove 610, realizing the effect of winding the light strip 400 while pulling, and reducing the space occupied when the light strip 400 is disassembled.

[0032] Reference Figure 3 and Figure 4 , the locking assembly 700 includes a fixed post 710 and a locking ring 720. The fixed post 710 is installed at the splicing intersection of the four light guide plate bodies 300. The fixed post 710 is used to contact the guiding block 500 to limit the guiding block 500 from continuing to move along the relief groove 310. An arc groove is formed at one or two corners of the light guide plate body 300, and the arc groove communicates with the relief groove 310. After the light guide plate bodies 300 are spliced together, a space for accommodating the fixed post 710 is formed by a plurality of arc grooves. A reflective film is provided on the inner wall of the arc groove, which does not affect the light reflected from the light-emitting surface of the light guide plate body 300.

[0033] Reference Figure 4 , the locking ring 720 is in a circular ring shape. The locking ring 720 is rotatably installed between the fixed post 710 and the bottom plate 100 with its own central axis as the rotation center. The fixed post 710 is provided with a first installation hole 711 for the locking ring 720 to rotate, and the bottom plate 100 is provided with a second installation hole 110 for the locking ring 720 to rotate. One orifice of the first installation hole 711 and the second installation hole 110 communicates with the external environment. When the locking ring 720 is inserted into the first installation hole 711 and the second installation hole 110, a part of the locking ring 720 is located outside the bottom plate 100, which is convenient for manual rotation of the locking ring 720.

[0034] Reference Figure 5 and Figure 6 , the locking rings 720 and the guiding blocks 500 are in one-to-one correspondence, and the locking ring 720 is provided with a notch 721. When the guiding block 500 has not contacted the fixed post 710, one end of the locking ring 720 is located inside the bottom plate 100, and the notch 721 faces the relief groove 310, so that the guiding block 500 can smoothly slide along the relief groove 310 to contact the fixed post 710. When the guiding block 500 contacts the fixed post 710, the guiding block 500 is provided with a jack 510 and the jack 510 communicates with the second installation hole 110. Rotate the locking ring 720 so that one end of the locking ring 720 is inserted into the jack 510 of the guiding block 500. The locking ring 720 is simultaneously in the first installation hole 711, the second installation hole 110 and the jack 510.

[0035] Reference Figure 6, after the locking ring 720 and the guiding block 500 are inserted, in order to prevent the locking ring 720 from moving further, the locking assembly 700 further includes a limiting member 730 installed on the fixing post 710. The limiting member 730 is a limiting rod. A third installation hole 712 is formed in the end face of the fixing post 710 facing away from the light guide plate body 300. A plurality of first installation holes 711 and the third installation hole 712 are in a communicating relationship, and the locking ring 720 can be contacted within the third installation hole 712. Internal threads are provided on the inner wall of the third installation hole 712, external threads are distributed on the outer wall of the limiting rod, and the limiting rod is threadedly installed in the fixing post 710. A chamfer is provided on the outer rod wall of the limiting rod, and the chamfer contacts a plurality of locking rings 720 simultaneously, and the limiting rod exerts a pressing force on the locking ring 720, increasing the friction between the locking ring 720 and the fixing post 710, thereby restricting the locking ring 720 from rotating further.

[0036] Through the cooperation of the locking ring 720 and the limiting rod, even if the limiting rod is separated from the fixing post 710, the locking ring 720 will not rotate randomly, but any one of the locking rings 720 can be manually pushed to rotate to unlock the corresponding guiding block 500, and the remaining locking rings 720 remain stationary.

[0037] The surface of the fixing post 710 facing away from the light guide plate body 300 is flush with the bottom surface of the bottom plate 100. After the limiting rod is installed in place, the limiting rod is located within the third installation hole 712. The entire locking assembly 700 will not occupy too much space. When the bottom plate 100 is installed on other planes, since the locking ring 720 protrudes outside the bottom plate 100, the locking ring 720 can form a small spacing between the bottom plate 100 and other planes, which helps the bottom plate 100 dissipate heat.

[0038] Furthermore, referring to Figure 5 , the locking ring 720 is a hollow structure, and a plurality of through holes 722 are provided on the outer wall of the locking ring 720. The through holes 722 are in communication with the hollow structure, and openings are also provided at both ends of the locking ring 720.

[0039] Referring to Figure 6 and Figure 7 , the guiding block 500 is provided with a first heat dissipation hole 520, and the first heat dissipation hole 520 is in communication with the locking ring 720 through the through hole 722. The fixing post 710 includes a main rod 713 and a sub-rod 714. The main rod 713 is fixedly connected to the bottom plate 100, ensuring the overall stability. The sub-rod 714 is fixedly installed on the main rod 713. The sub-rods 714 correspond to the guiding blocks 500 one by one, and there is a spacing between the sub-rods 714, providing space for the installation and operation of other components, and also contributing to air flow and improving the heat dissipation effect. The locking ring 720 is inserted into the sub-rod 714, and a second heat dissipation hole 715 is provided on the rod wall of the sub-rod 714. The second heat dissipation hole 715 is in communication with the first installation hole 711. While the locking ring 720 fixes the guiding block 500, it can also serve as a circulation channel for internal air and external air.

[0040] Referring toFigure 8 If there are more than three light guide plate bodies 300 in the same row, relief grooves 310 are also formed in the side walls of the light guide plate bodies 300 located in the middle position. No light strip 400 is installed in the relief grooves 310, so a reflective film is provided and a limiting block 800 is installed. The shape of the limiting block 800 is the same as that of the guiding block 500. The limiting block 800 is provided with a limiting hole 810 for inserting the locking ring 720 and a third heat dissipation hole communicating with the limiting hole 810. The limiting block 800 contacts the sub-bar 714. There may be two limiting blocks 800 installed in the relief groove 310 of the middle light guide plate body 300, which are respectively in contact with the sub-bar 714 at the intersection. A connecting plate is connected between the two limiting blocks 800, and the connecting plate does not contact the inner wall of the relief groove 310. During the process of splicing the light guide plate bodies 300, the limiting block 800 is installed between the two light guide plate bodies 300, and the locking ring 720 is rotated to lock the limiting block 800 first.

[0041] The implementation principle of a light guide plate splicing structure according to an embodiment of the present application is as follows: During the actual splicing process, two light guide plate bodies 300 are spliced in sequence. After the adjacent two light guide plate bodies 300 are aligned, the relief grooves 310 communicate with each other. The guiding block 500 is pushed to move along the bottom plate 100 and the light guide plate body 300. When the guiding block 500 abuts against the fixing column 710, the light strip 400 is installed between the two light guide plate bodies 300. First, the guiding block 500 is fixed by the locking assembly 700, that is, the locking ring 720 is rotated. After one end of the locking ring 720 passes through the guiding block 500, the locking ring 720 is connected to the guiding block 500, the fixing column 710, and the bottom plate 100 at one time, so that the guiding block 500 is fixed on the bottom plate 100. Then the positioning block 600 is fixedly installed on the frame 200. At this time, the light strip 400 is installed in the relief groove 310 in a straightened state, and the entire light guide plate splicing structure is completed and in a stable working state.

[0042] When a certain light strip 400 is damaged, the corresponding positioning block 600 is disassembled, and the locking assembly 700 is unlocked, that is, the limiting rod is screwed out of the third installation hole 712, and the locking ring 720 is rotated so that one end of it is disengaged from the insertion hole 510 of the guiding block 500, and the fixing of the guiding block 500 is released, so that the light strip 400 can be disassembled from the frame 200, while the relative positions of the light guide plate body 300 and the bottom plate 100 remain unchanged, thus facilitating the replacement of the light strip 400 and improving the replacement efficiency of the light strip 400.

[0043] In a second aspect, an embodiment of the present application discloses a method for splicing a light guide plate.

[0044] A light guide plate splicing method, using the above-mentioned light guide plate splicing structure, places the base plate 100 on a flat workbench to ensure that it is stable and motionless; sequentially splices the light guide plate bodies 300 on the base plate 100, aligning two adjacent light guide plate bodies 300 so that the positioning grooves 310 are interconnected; during splicing, pay attention to maintaining a uniform gap between the light guide plate bodies 300 to avoid misalignment or overlap, ensuring that each light guide plate body 300 can be installed with a corresponding light strip 400, and then installs the frame 200. The frame 200 and the base plate 100 are fixedly bonded to each other, so that the frame 200 initially fixes the light baffle; The two ends of the light strip 400 are connected to the guide block 500 and the fixed block respectively. The guide block 500 slides into the clearance groove 310. The push rod can be used to push the guide block 500 to slide. The guide block 500 and the light strip 400 are gradually installed in the clearance groove 310. When the guide block 500 and the fixed column 710 are in contact, the guide block 500 has further reinforced the two adjacent light guide plate bodies 300. When the guide block 500 abuts against the fixed post 710, the lock ring 720 is rotated so that one end of the lock ring 720 is inserted into the insertion hole 510 of the guide block 500. The lock ring 720 is simultaneously inserted into the first mounting hole 711 of the fixed post 710, the second mounting hole 110 of the base plate 100, and the insertion hole 510 of the guide block 500, thereby achieving preliminary fixation of the guide block 500. Thread the limiting member 730 (limiting rod) into the third mounting hole 712 of the fixing column 710 until the rod wall of the limiting rod abuts against the locking ring 720, restricting the locking ring 720 from further rotation and ensuring that the guide block 500 is firmly fixed to the base plate 100; The positioning block 600 is inserted into the through-slot 210 of the frame 200 so that the positioning block 600 contacts the inner wall of the through-slot 210. Then, the cover 220, which is threadedly connected to the frame 200, is screwed into the through-slot 210 and pressed against the positioning block 600, so that the positioning block 600 is fixed in the frame 200. After the guide block 500 is secured and the positioning block 600 is installed, the light strip 400 should be installed in a straight position within the clearance groove 310. At this point, one end of the light strip 400 is connected to the fixing post 710 via the guide block 500, and the other end is connected to the frame 200 via the positioning block 600, ensuring the stability of the light strip 400 and uniform light transmission.

[0045] If a light strip 400 is damaged, remove the corresponding positioning block 600 (unscrew the cover 220 and remove the positioning block 600), unlock the locking assembly 700 (unscrew the limit rod and rotate the locking ring 720 to disengage one end from the socket 510 of the guide block 500), and release the guide block 500 to remove the light strip 400 from the frame 200. Then, install a new light strip 400 and reassemble it according to the above assembly steps.

[0046] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
