Description

Technical Field

[0001] This utility model relates to the field of light guide plate technology, and in particular to a quantum dot-based Fresnel lens array type light guide plate. Background Technology

[0002] A light guide plate is a material used in optical applications. It is usually made of transparent plastic or glass and can effectively guide and disperse light. With the rapid development of display technology, the application of display devices such as liquid crystal displays and organic light-emitting diodes is becoming more and more widespread. In order to improve the brightness, color performance and energy efficiency of these devices, the design of the backlight has become particularly important. Therefore, a quantum dot-based Fresnel lens array type light guide plate is needed.

[0003] Light guide plates typically need to be fixed to a bracket first and then tightened with bolts and nuts. Since each bolt needs to be tightened individually, the entire installation process can be time-consuming, especially when multiple light guide plates need to be replaced. The overall disassembly and reinstallation will be more cumbersome, reducing maintenance efficiency. Multiple light guide plates are usually glued together, which means that once a light guide plate is damaged, the overall disassembly and replacement becomes unavoidable, leading to waste of resources and additional economic burden. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantum dot-based Fresnel lens array light guide plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quantum dot-based Fresnel lens array light guide plate includes a mounting base. Multiple light guide plate bodies are evenly arrayed on the top of the mounting base. T-shaped plates are symmetrically arranged at both ends of each of the multiple light guide plate bodies. A first slider is fixed to the bottom end of each of the multiple T-shaped plates. A snap-fit ​​mechanism for snapping the light guide plate bodies is provided at both ends of each of the multiple light guide plate bodies. A horizontal plate is provided on the top of each of the multiple light guide plate bodies. A first fixing mechanism for fixing the horizontal plate is provided at both ends of each of the horizontal plates. A second fixing mechanism for fixing the multiple light guide plate bodies is provided at both ends of the top of the mounting base. A buffer mechanism for cushioning the mounting base is provided at the bottom. During use, the snap-fit ​​mechanism and the first fixing mechanism enable rapid installation and disassembly of the light guide plate bodies without the need for bolts and nuts, saving time and improving work efficiency. The design of the second fixing mechanism allows for detachable fixing of the multiple light guide plate bodies, eliminating the need for adhesive application and allowing for individual replacement instead of overall replacement, saving resources and reducing economic burden.

[0007] Preferably, the snap-fit ​​mechanism includes two U-shaped plates, which are respectively fixed to the symmetrical ends of one of the light guide plate bodies. The two U-shaped plates are also adapted to the two T-shaped plates. The ends of the light guide plate body are fixed to the two U-shaped plates respectively. When installing the light guide plate body, the two U-shaped plates are snapped into the surfaces of the two T-shaped plates respectively to complete the initial fixation of the light guide plate body.

[0008] Preferably, the first fixing mechanism includes a second slide groove, which is opened at one end of one of the horizontal plates and has a constricted opening. A second slider is slidably connected to the inner sidewall of the second slide groove, and a rectangular block is fixed to the sidewall of the second slider. A return spring is provided inside the second slide groove. A rectangular hole is opened on the sidewall of one of the T-shaped plates, and the rectangular block and the rectangular hole are adapted to each other. When one rectangular block is inserted into the rectangular hole and the other rectangular block is pressed, the second slider moves along the inner sidewall of the second slide groove, so that the return spring is in a compressed state. When the other rectangular block and the other rectangular hole are in a horizontal state, the other rectangular block is released. Under the reaction of the compressed return spring, the other rectangular block is pushed to move in the opposite direction until the other rectangular block enters the other rectangular hole, thus completing the fixing of the light guide plate body. There is no need to fix it with bolts and nuts. When it is necessary to disassemble the light guide plate body, the operation can be reversed, saving time and improving work efficiency.

[0009] Preferably, the second fixing mechanism includes a plurality of first sliders, which are respectively fixed to the bottom of a plurality of T-shaped plates. A first groove is provided on one side of the top of the mounting base. A lead screw is rotatably connected inside the first groove, and one end of the lead screw passes through the outer wall of one end of the mounting base. The plurality of first sliders are all sleeved on the side wall of the lead screw. A lead screw nut is slidably connected to the side wall of the first groove, and the lead screw nut and the lead screw are adapted to each other. A connecting spring is sleeved on the side wall of the lead screw. One end of the connecting spring is fixed to the lead screw nut, and the other end of the connecting spring is fixed to one of the first sliders. A hand is rotatably connected to the outer wall of one end of the mounting base. The two handwheels are fixed at one end to the lead screw. Rotating the two handwheels causes the two lead screws to rotate. As the lead screws rotate, they work in conjunction with the two lead screw nuts to gradually bring the light guide plate bodies closer together. This causes the two connecting springs to gradually compress. Under the reaction force of the compressed connecting springs, the multiple first sliders are pushed into a tightly compressed state, resulting in a tight fit between the multiple light guide plate bodies. This completes the fixation between the multiple light guide plate bodies, eliminating the need for adhesive application between them. If one of the light guide plate bodies is damaged, it can be replaced individually instead of replacing the entire light guide plate, saving resources and reducing the economic burden.

[0010] Preferably, the buffer mechanism includes a base, which is disposed at the bottom of the mounting base. Damping telescopic rods are fixed at the four corners of the top of the base, and the telescopic ends of the four damping telescopic rods are fixed to the bottom of the mounting base. Damping springs are sleeved on the outer walls of the four damping telescopic rods. When an external force is applied to the mounting base, the damping telescopic rods will begin to compress. During this process, the internal damping liquid or gas is forced to flow, generating resistance, thereby reducing the speed and impact force of the movement. At the same time, the damping springs are also compressed, which can effectively reduce the instantaneous transmission of impact force, so that the impact force will not directly act on the light guide plate body, thus extending the service life of the light guide plate body.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, this device, through the design of the snap-fit ​​mechanism and the first fixing mechanism, enables the quick installation and disassembly of the light guide plate body without the need for bolts and nuts for installation and fixing. This design saves a lot of time and improves work efficiency.

[0013] 2. The design of the second fixing mechanism allows for the detachable fixing of multiple light guide plate bodies without the need for adhesive application. This means that if one of the light guide plate bodies is damaged, it can be replaced individually instead of replacing the entire plate, which effectively saves resources and reduces the economic burden.

[0014] 3. The design of the buffer mechanism can effectively absorb external impacts, reduce the transmission of movement speed and impact force. This design helps protect the main body of the light guide plate, reduce the risk of damage caused by external impacts, and extend its service life. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1 - Figure 6 A quantum dot-based Fresnel lens array light guide plate includes a mounting base 1. Multiple light guide plate bodies 10 are evenly arrayed on the top of the mounting base 1. T-shaped plates 8 are symmetrically arranged at both ends of each of the multiple light guide plate bodies 10. First sliders 13 are fixed to the bottom ends of each of the multiple T-shaped plates 8. Clamping mechanisms for engaging the light guide plate bodies 10 are provided at both ends of each of the multiple light guide plate bodies 10. Horizontal plates 9 are provided on the top of each of the multiple light guide plate bodies 10. First fixing mechanisms for fixing the horizontal plates 9 are provided at both ends of each of the horizontal plates 9. Multiple light guide plates are fixed at both ends of the top of the mounting base 1. The second fixing mechanism of the main body 10 of the light guide plate has a buffer mechanism at the bottom of the mounting base 1 for buffering the mounting base 1. During use, the device can quickly install and disassemble the main body 10 of the light guide plate through the design of the snap-fit ​​mechanism and the first fixing mechanism. There is no need to use bolts and nuts for installation and fixing, which saves a lot of time and improves work efficiency. Through the design of the second fixing mechanism, the fixing method between multiple main bodies 10 of the light guide plate is detachable. There is no need for glue treatment, and they can be directly replaced individually without replacing the whole body, saving resources and reducing economic burden.

[0024] In this utility model, the snap-fit ​​mechanism includes two U-shaped plates 14, which are respectively fixed to the symmetrical ends of one of the light guide plate bodies 10. The two U-shaped plates 14 are respectively adapted to two of the T-shaped plates 8. The ends of the light guide plate body 10 are fixed to the two U-shaped plates 14 respectively. When installing the light guide plate body 10, the two U-shaped plates 14 are snapped into the surfaces of the two T-shaped plates 8 respectively, so as to complete the initial fixation of the light guide plate body 10.

[0025] In this invention, the first fixing mechanism includes a second sliding groove 16, which is located at one end of one of the horizontal plates 9 and has a constricted opening. A second slider 18 is slidably connected to the inner wall of the second sliding groove 16, and a rectangular block 19 is fixed to the side wall of the second slider 18. A return spring 17 is provided inside the second sliding groove 16. A rectangular hole 15 is provided on the side wall of one of the T-shaped plates 8, and the rectangular block 19 and the rectangular hole 15 are adapted to each other. When one of the rectangular blocks 19 is inserted into one of the rectangular holes 15 and the other rectangular block 19 is pressed, the second sliding groove 16... Block 18 moves along the inner wall of the second slide groove 16, causing the return spring 17 to be in a compressed state. When the other rectangular block 19 and the other rectangular hole 15 are in a horizontal state, the other rectangular block 19 is released. Under the reaction of the compressed return spring 17, the other rectangular block 19 is pushed to move in the opposite direction until the other rectangular block 19 enters the interior of the other rectangular hole 15, thus completing the fixation of the light guide plate body 10. There is no need to fix it with bolts and nuts. When it is necessary to disassemble the light guide plate body 10, the operation can be reversed, saving time and improving work efficiency.

[0026] In this utility model, the second fixing mechanism includes multiple first sliders 13, which are respectively fixed to the bottom of multiple T-shaped plates 8. A first groove 3 is provided on one side of the top of the mounting base 1. A lead screw 4 is rotatably connected inside the first groove 3, and one end of the lead screw 4 passes through the outer wall of one end of the mounting base 1. Multiple first sliders 13 are all sleeved on the side wall of the lead screw 4. A lead screw nut 5 is slidably connected to the side wall of the first groove 3, and the lead screw nut 5 and the lead screw 4 are adapted to each other. A connecting spring 6 is sleeved on the side wall of the lead screw 4. One end of the connecting spring 6 is fixed to the lead screw nut 5, and the other end of the connecting spring 6 is fixed to one of the first sliders 13. A handwheel 7 is rotatably connected to the outer wall of one end of the mounting base 1. One end of 7 is fixed to the lead screw 4. Rotating the two handwheels 7 rotates the two lead screws 4, which in turn rotate the two lead screw nuts 5. As the two lead screws 4 rotate, they gradually move closer to the light guide plate body 10, causing the two connecting springs 6 to gradually compress. Under the reaction force of the connecting springs 6 in the compressed state, the multiple first sliders 13 are pushed to a tight compression state, so that the multiple light guide plate bodies 10 are in a tight fit. This completes the fixation between the multiple light guide plate bodies 10. That is, no glue treatment is required between the multiple light guide plate bodies 10. When one of the light guide plate bodies 10 is damaged, it can be replaced individually without replacing the whole body, saving resources and reducing economic burden.

[0027] In this utility model, the buffer mechanism includes a base 2, which is disposed at the bottom of the mounting base 1. Damping telescopic rods 11 are fixed at the four corners of the top of the base 2, and the telescopic ends of the four damping telescopic rods 11 are fixed to the bottom of the mounting base 1. Damping springs 12 are sleeved on the outer walls of the four damping telescopic rods 11. When an external force is applied to the mounting base 1, the damping telescopic rods 11 will begin to compress. During this process, the internal damping liquid or gas is forced to flow, generating resistance, thereby reducing the speed and impact force of the movement. At the same time, the damping springs 12 will also be compressed, which can effectively reduce the instantaneous transmission of impact force, so that the impact force will not directly act on the light guide plate body 10, thus extending the service life of the light guide plate body 10.

[0028] Working principle: During use, multiple T-shaped plates 8 are fixed to multiple first sliders 13 one by one, and the two ends of the light guide plate body 10 are fixed to two U-shaped plates 14. When installing the light guide plate body 10, the two U-shaped plates 14 are respectively inserted into the surfaces of the two T-shaped plates 8 to complete the initial fixation of the light guide plate body 10. At this time, one of the rectangular blocks 19 is inserted into one of the rectangular holes 15, and the other rectangular block 19 is pressed. At this time, the second slider 18 moves along the inner wall of the second slide groove 16, so that the return spring 17 is compressed. In the compressed state, when the other rectangular block 19 and the other rectangular hole 15 are horizontal, releasing the other rectangular block 19, under the reaction action of the return spring 17, pushes the other rectangular block 19 to move in the opposite direction until the other rectangular block 19 enters the other rectangular hole 15. This completes the connection between the horizontal plate 9 and the two T-shaped plates 8, thus fixing the light guide plate body 10 without the need for bolts and nuts. When it is necessary to disassemble the light guide plate body 10, the operation can be reversed, saving time and improving work efficiency. When multiple light guide plates are connected... When the main body 10 is fixed one by one, the two handwheels 7 are rotated, which in turn drives the two lead screws 4 to rotate. The rotation of the two lead screws 4, together with the two lead screw nuts 5, gradually guides the light guide plate main body 10 closer together, so that the two connecting springs 6 are gradually compressed. Under the reaction of the connecting springs 6 in the compressed state, the multiple first sliders 13 are pushed to a tight compression state, so that the multiple light guide plate main bodies 10 are in a tight fit, thus completing the fixing between the multiple light guide plate main bodies 10. That is, no glue treatment is required between the multiple light guide plate main bodies 10. When one of the light guide plate main bodies 10 is damaged, it can be replaced individually without replacing the whole body, saving resources and reducing economic burden. Moreover, during use, when an external force is applied to the mounting base 1, the damping telescopic rod 11 will start to compress. During this process, the internal damping liquid or gas is forced to flow, generating resistance, thereby reducing the speed and impact force of the movement. At the same time, the damping spring 12 is also compressed, which can effectively reduce the instantaneous transmission of impact force, so that the impact force will not directly act on the light guide plate main body 10, extending the service life of the light guide plate main body 10.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
