Description

Technical Field

[0001] The present 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 edge-entry backlight module: the light emitted by the light source enters the light guide plate from at least one side to generate countless total reflected lights. When the total reflected light encounters the microstructure on the light guide plate, it diffuses to all angles, generating refracted light and scattered light. The refracted light and scattered light destroy the reflection conditions and are emitted from the front of the light guide plate, making the entire light guide plate panel emit uniform, high-brightness light.

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

[0004] Usually, after multiple light guide plate bodies are spliced ​​together, if the light source corresponding to one of the light guide plate bodies is damaged, multiple light guide plate bodies need to be disassembled for replacement, which is troublesome. Summary of the Invention

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

[0006] In a first aspect, the present application provides a light guide plate splicing structure, which adopts the following technical solution:

[0007] A light guide plate splicing structure, comprising:

[0008] base plate;

[0009] The light guide plate bodies that are spliced ​​together are installed on the bottom plate, and some side walls of the light guide plate bodies are provided with recesses, while the remaining side walls are provided with reflective films;

[0010] A frame, used to fix the light guide plate body, the frame being fixedly mounted on the bottom plate;

[0011] A light strip is installed in the recess;

[0012] A guide block is installed on one end of the light strip.

[0013] A positioning block is detachably mounted on the frame, and one end of the light strip away from the guide block is connected to the positioning block;

[0014] A locking assembly is installed on the base plate and is used to fix the guide block.

[0015] 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.

[0016] Optionally, the locking assembly includes:

[0017] A fixing column, fixedly mounted on the bottom plate and located at the intersection of the plurality of light guide plate bodies;

[0018] 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.

[0019] A limiting member is installed on the fixing column and is used to limit the rotation of the locking ring.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] Optionally, the fixed column includes a main rod and a sub-rod, the main rod is fixedly connected to the base plate, the sub-rod is fixedly installed on the main rod, the sub-rod and the guide block correspond one to one, and a distance is left between the sub-rods.

[0024] By adopting this technical solution, the main rod is fixed to the base plate, ensuring overall stability. The sub-rods correspond one-to-one with the guide blocks, facilitating precise fixing of the guide blocks. Spacing between the sub-rods provides space for the installation and operation of other components and increases airflow. In particular, the ends of the multiple light strips are close to the fixing column, which facilitates airflow.

[0025] Optionally, the locking ring is a hollow structure, a through hole is provided on the outer wall of the locking ring, the guide block is provided with a first heat dissipation hole for connecting with the socket, and the sub-rod is provided with a second heat dissipation hole for connecting with the first mounting hole.

[0026] By adopting the above technical solution, the locking ring has a hollow structure and a through hole is opened on the outer wall, the guide block has a first heat dissipation hole, and the sub-rod has a second heat dissipation hole. These heat dissipation holes are interconnected, so that the locking ring can fix the guide block 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.

[0027] Optionally, the guide block is a cylindrical structure, the cross-section of the clearance groove is an arc-shaped structure, and the guide block is attached to the inner wall of the clearance groove.

[0028] By adopting the above technical solution, the cylindrical guide block and the arc-shaped cross-section clearance groove fit together. This design allows the guide block to move more smoothly in the clearance groove, reduces friction and resistance, and facilitates the installation and adjustment of the light strip. In addition, the cylindrical wire block can also fix the two adjacent light guide plate bodies.

[0029] 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 strip is wound and stored in the receiving groove.

[0030] By adopting the above technical solution, when the light strip needs to be disassembled or stored, the positioning block is separated from the frame and rotated, and the light strip can be wound and stored in the receiving groove, achieving the effect of storing the light strip while pulling. The positioning block can be rotated in a position close to the frame, and can also reduce the space occupied by the light strip when it is disassembled.

[0031] In a second aspect, the present application provides a light guide plate splicing method, which adopts the following technical solution:

[0032] 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.

[0033] 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.

[0034] In summary, this application has at least one of the following beneficial effects:

[0035] 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.

[0036] 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. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0047] In a first aspect, an embodiment of the present application discloses a light guide plate splicing structure.

[0048] Reference Figure 1 and Figure 2A light guide plate splicing structure includes a base plate 100, a frame 200, and a light guide plate body 300 and a light strip 400 mounted on the base plate 100. The overall structure uses the base plate 100 as a supporting platform. The various components are installed according to specific positions and connection relationships to achieve 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 the side of the base plate 100 closest to the light guide plate body 300.

[0049] Reference Figure 2 The light guide plate bodies 300 of the embodiment of the present application are spliced ​​into two rows, and each row of light guide plate bodies 300 is fixedly mounted on the base plate 100 via a frame 200. The frame 200 is fixedly mounted on the base plate 100, and the frame 200 serves to fix the light guide plate bodies 300, ensuring that the light guide plate bodies 300 maintain a stable position during the splicing process. Some side walls of the light guide plate bodies 300 are provided with a clearance groove 310, and the remaining side walls are provided with a reflective film. The light guide plate bodies 300 are spliced ​​together and installed on the base plate 100. The clearance grooves 310 of the two light guide plate bodies 300 are used to accommodate the light strips 400, so that the light strips 400 can cooperate well with the light guide plate bodies 300. The reflective film helps to reflect and propagate light within the light guide plate body 300, thereby improving the utilization rate of light.

[0050] Reference Figure 2 and Figure 3 , the light strip 400 is installed on the base plate 100 and is located in the clearance 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 cut surface is provided on the side of the guide block 500 close to the base plate 100, and the cut surface is in contact with the base plate 100. The cross-section of the clearance groove 310 is an arc-shaped structure, and the guide block 500 is in contact with the inner wall of the clearance groove 310. This design makes the guide block 500 move more smoothly in the clearance 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 two adjacent light guide plate bodies 300. After 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 clearance groove 310, and a locking assembly 700 for locking the guide block 500 is installed on the base plate 100. A positioning block 600 is installed at the other end of the light strip 400 , and a switch of the light strip 400 is also installed on the positioning block 600 .

[0051] Reference Figure 4The positioning block 600 is detachably mounted on the frame 200. After the guide block 500 is locked, the positioning block 600 is fixed to the frame 200, so that the light strip 400 is stretched and positioned within the clearance groove 310. The side wall of the frame 200 is provided with a through groove 210 for the positioning block 600, the light strip 400, and the guide block 500 to disengage. 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. The cover 220 is screwed into the through groove 210 and pressed against the positioning block 600, thereby securing the positioning block 600 within the frame 200.

[0052] The positioning block 600 is provided with a receiving groove 610. When the light strip 400 needs to be disassembled or stored, the positioning block 600 is separated from the frame 200 and rotated, and the light strip 400 can be wound and stored in the receiving groove 610, thereby achieving the effect of storing the light strip 400 while pulling it, reducing the space occupied by the light strip 400 when it is disassembled.

[0053] Reference Figure 3 and Figure 4 The locking assembly 700 includes a fixing post 710 and a locking ring 720. The fixing post 710 is installed at the intersection of the four light guide plate bodies 300. The fixing post 710 is used to contact the guide block 500 to limit the guide block 500 from continuing to move along the clearance groove 310. An arc groove is provided at one or two corners of the light guide plate body 300, and the arc groove is connected to the clearance groove 310. After the light guide plate bodies 300 are spliced ​​and intersected, multiple arc grooves form a space for accommodating the fixing post 710. A reflective film is provided on the inner wall of the arc groove so as not to affect the light-emitting surface of the light guide plate body 300 from reflecting light.

[0054] Reference Figure 4 The locking ring 720 is in the shape of a circular ring. The locking ring 720 is rotatably installed between the fixing column 710 and the base plate 100 with its own central axis as the rotation center. The fixing column 710 is provided with a first mounting hole 711 for the rotation of the locking ring 720. The base plate 100 is provided with a second mounting hole 110 for the rotation of the locking ring 720. One opening of the first mounting hole 711 and the second mounting hole 110 is connected to the external environment. When the locking ring 720 is inserted into the first mounting hole 711 and the second mounting hole 110, part of the locking ring 720 is located outside the base plate 100, which is convenient for manual rotation of the locking ring 720.

[0055] Reference Figure 5 and Figure 6, the locking ring 720 and the guide block 500 correspond one to one, and the locking ring 720 is provided with a notch 721. When the guide block 500 has not yet contacted the fixed column 710, one end of the locking ring 720 is located in the base plate 100, and the notch 721 faces the clearance groove 310, so that the guide block 500 can slide smoothly along the clearance groove 310 until it contacts the fixed column 710. When the guide block 500 contacts the fixed column 710, the guide block 500 is provided with a socket 510 and the socket 510 is connected to the second mounting hole 110. The locking ring 720 is rotated so that one end of the locking ring 720 is inserted into the socket 510 of the guide block 500. The locking ring 720 is simultaneously in the first mounting hole 711, the second mounting hole 110, and the socket 510.

[0056] Reference Figure 6 When the lock ring 720 and the guide block 500 are plugged in, in order to prevent the lock ring 720 from moving further, the locking assembly 700 further includes a limiter 730 mounted on the fixed column 710. The limiter 730 is a limiter rod. The end surface of the fixed column 710 facing away from the light guide plate body 300 is provided with a third mounting hole 712. The multiple first mounting holes 711 and the third mounting holes 712 are all connected, and the lock ring 720 can be contacted in the third mounting hole 712. The inner wall of the third mounting hole 712 is provided with an internal thread, and the outer wall of the limiter rod is provided with an external thread. The limiter rod is threadedly mounted in the fixed column 710. The outer wall of the limiter rod is provided with a chamfered corner, which contacts multiple lock rings 720 at the same time. In addition, the limiter rod has a squeezing effect on the lock ring 720, increasing the friction between the lock ring 720 and the fixed column 710, thereby limiting the lock ring 720 from continuing to rotate.

[0057] Through the cooperation between the locking ring 720 and the limiting rod, even if the limiting rod is separated from the fixing column 710, the locking ring 720 will not rotate at will, but any one of the locking rings 720 can be manually pushed to rotate and unlock the corresponding guide block 500, and the other locking rings 720 remain stationary.

[0058] The side of the fixing post 710 facing away from the light guide plate body 300 is flush with the bottom surface of the base plate 100. Once the stopper is in place, it rests within the third mounting hole 712. The entire locking assembly 700 does not take up excessive space. When the base plate 100 is mounted on another flat surface, the protruding locking ring 720 creates a smaller gap between the base plate 100 and the other surface, facilitating heat dissipation.

[0059] Further, refer to Figure 5 The locking ring 720 is a hollow structure. The outer wall of the locking ring 720 is provided with a plurality of through holes 722 . The through holes 722 are connected to the hollow structure. Both ends of the locking ring 720 are also provided with openings.

[0060] Reference Figure 6 and Figure 7, the guide block 500 is provided with a first heat dissipation hole 520, and the first heat dissipation hole 520 is connected to the locking ring 720 through the through hole 722. The fixed column 710 includes a main rod 713 and a sub-rod 714. The main rod 713 is fixedly connected to the base plate 100 to ensure the overall stability. The sub-rod 714 is fixedly installed on the main rod 713. The sub-rod 714 and the guide block 500 correspond one to one. There is a spacing between the sub-rods 714, which provides space for the installation and operation of other components, and also helps air flow and improves the heat dissipation effect. The locking ring 720 is inserted into the sub-rod 714. The rod wall of the sub-rod 714 is provided with a second heat dissipation hole 715. The second heat dissipation hole 715 is connected to the first mounting hole 711. While the locking ring 720 fixes the guide block 500, it can also serve as a circulation channel for internal air and external air.

[0061] Reference Figure 8 If there are more than three light guide plate bodies 300 in the same row, the side wall of the light guide plate body 300 located in the middle position is also provided with a clearance groove 310. No light strip 400 is installed in the clearance groove 310, so a reflective film is provided. A limit block 800 is also installed. The shape of the limit block 800 is the same as that of the guide block 500. The limit block 800 is provided with a limit hole 810 for inserting the lock ring 720 and a third heat dissipation hole connected to the limit hole 810. The limit block 800 contacts the sub-rod 714. There can be two limit blocks 800 installed in the clearance groove 310 of the light guide plate body 300 located in the middle, and each of them contacts the sub-rod 714 at the intersection. A connecting strip 820 is connected between the two limit blocks 800, and the connecting strip 820 does not contact the inner wall of the clearance groove 310. During the process of splicing the light guide plate bodies 300 , the limit block 800 is installed between the two light guide plate bodies 300 , and the lock ring 720 is rotated to first lock the limit block 800 .

[0062] The implementation principle of the light guide plate splicing structure in the embodiment of the present application is as follows:

[0063] During the actual splicing process, the two light guide plate bodies 300 are spliced ​​in sequence. After the adjacent light guide plate bodies 300 are aligned, the clearance grooves 310 are connected to each other. The guide block 500 is pushed along the base plate 100 and the light guide plate body 300. When the guide block 500 abuts the fixing post 710, the light strip 400 is installed between the two light guide plate bodies 300. First, the guide block 500 is fixed using the locking assembly 700. That is, the locking ring 720 is rotated so that one end of the locking ring 720 passes through the guide block 500. The locking ring 720 is connected to the guide block 500, the fixing post 710, and the base plate 100 at one time, so that the guide block 500 is fixed to the base 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 clearance groove 310 in a straight state. The entire light guide plate splicing structure is spliced ​​and is in a stable working state.

[0064] When a light strip 400 is damaged, the corresponding positioning block 600 is removed and the locking assembly 700 is unlocked. Even if the limiting rod is unscrewed from the third mounting hole 712, the locking ring 720 is rotated to disengage one end of it from the socket 510 of the guide block 500, thereby releasing the fixation of the guide block 500 and allowing the light strip 400 to be removed from the frame 200. The relative positions of the light guide plate body 300 and the base plate 100 remain unchanged, thereby facilitating the replacement of the light strip 400 and improving the efficiency of replacing the light strip 400.

[0065] In a second aspect, an embodiment of the present application discloses a light guide plate splicing method.

[0066] 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;

[0067] 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.

[0068] 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.

[0069] 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;

[0070] 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.

[0071] 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.

[0072] 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.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
