Description

Technical Field

[0001] This utility model relates to the field of light guide plate technology, specifically to a portable light guide plate. Background Technology

[0002] Light guide plates, as optical components, are widely used in lighting, display, and decoration. Their main function is to uniformly conduct and diffuse light emitted from a light source to achieve specific light output effects. Traditional light guide plates typically employ a single, rigid plate structure, made of transparent materials such as polymethyl methacrylate (PMMA) or polycarbonate (PC). Light sources (such as LEDs) are placed on the sides of the plate, utilizing the principle of total internal reflection to achieve uniform light distribution. This structure offers good stability and light guiding performance in fixed installation scenarios, and is widely used in LCD backlight modules or large lighting equipment.

[0003] However, with the increasing demand for portable devices and mobile applications, the limitations of traditional rigid light guide plates are becoming increasingly apparent. First, the single rigid structure of traditional light guide plates is difficult to compress in size, making them inconvenient to carry, especially in scenarios requiring temporary installation or mobile use, resulting in high transportation and storage costs. Second, to meet the need for guiding light over a larger area, it is usually necessary to increase the size or number of light guide plates, which further exacerbates the portability problem. Furthermore, while some existing light guide plate designs attempt to expand the usable area by splicing multiple plates, their connection methods mostly employ fixed structures, such as adhesive or bolt connections. This method not only makes assembly and disassembly complex but also fails to effectively reduce the size after disassembly, making it difficult to meet the dual requirements of portability and flexibility.

[0004] In recent years, several improvement solutions have been proposed, such as using flexible materials to fabricate light guide plates to achieve a certain degree of flexibility. However, flexible light guide plates often struggle to maintain a stable planar structure when unfolded, and deformation can easily affect the uniformity of light guiding. Furthermore, existing technologies have attempted to connect multiple light guide plates using hinges or folding mechanisms, but the connecting components in these solutions are typically complex, increasing manufacturing costs. Additionally, the durability of the connections after repeated folding and use becomes a technological bottleneck. Utility Model Content

[0028] like Figures 1 to 7 As shown, this utility model provides a portable light guide plate, the structure of which includes: at least two light guide plate bodies 1, connecting components 2, and two connecting straps 3. The structural design of the portable light guide plate aims to achieve a balance between the stability of the light guiding function and portability.

[0029] Specifically, the light guide plate body 1 is a flat plate structure with light guiding function, and there are at least two of them. Each light guide plate body 1 has a mounting position (not shown in the figure) on its side for mounting a light source. The light source can be an existing LED light source or other suitable light source, used to provide light input to the light guide plate body 1 to achieve the light guiding function. The two connecting straps 3 are respectively disposed between the two light guide plate bodies 1 for flexible connection of the two light guide plate bodies 1. The connecting straps 3 are preferably made of flexible materials, such as rubber, silicone or flexible fabric, to ensure that the two light guide plate bodies 1 can be bent relative to each other in the folded state without damaging the connection structure. There are two connecting components 2, which are used to detachably connect the two light guide plate bodies 1 into a whole structure. The connecting components 2 can adopt buckles, magnetic parts, plugs or other suitable connecting mechanisms to realize the splicing and fixing of the two light guide plate bodies 1 in the unfolded state.

[0030] In use, the existing light source is first installed on the side mounting position of the light guide plate body 1 to provide the light input required for light guiding. Then, the two light guide plate bodies 1 are spliced ​​and fixed together by the connecting component 2, forming a stable planar structure. At this time, the light guiding surfaces of the two light guide plate bodies 1 are on the same plane, enabling uniform light transmission and output, meeting the light guiding requirements. After use, the two light guide plate bodies 1 are detached from the spliced ​​state by disassembling the connecting component 2. At this time, the two light guide plate bodies 1 are only connected by the connecting strap 3. Due to the flexibility of the connecting strap 3, the two light guide plate bodies 1 can be folded relative to each other, forming a folded state, thereby reducing the overall volume and facilitating carrying and storage.

[0031] The portable light guide plate of this invention, through the above-described structural design, not only forms a stable light guide structure when unfolded to meet usage requirements, but also can be folded after use via a flexible connecting strap for easy carrying, exhibiting high practicality and portability. Furthermore, the connection component 2 and the connecting strap 3 make the assembly and disassembly of the light guide plate simple and efficient, suitable for various application scenarios.

[0032] In this embodiment, the light guide plate body 1 adopts a multi-layer composite structure, specifically including a bottom shell 11, a reflective layer 12, a light guide layer 13, and a diffusion layer 14. The above layers are stacked and fixed in a specific order to achieve effective light transmission and uniform diffusion.

[0033] Specifically, the bottom shell 11 serves as the supporting structure for the light guide plate body 1, and is preferably made of aluminum plate, which has good rigidity and heat dissipation performance to provide stable mechanical support and assist in heat dissipation of the light source during operation. The upper surface of the bottom shell 11 is used to support the subsequent layers. The reflective layer 12 is fixedly installed on the upper surface of the bottom shell 11, and its function is to reflect the light propagating downward in the light guide layer 13 back upward to improve light utilization efficiency. The reflective layer 12 can be made of a high-reflectivity material, such as a reflective film or an optical thin plate coated with a reflective coating. The light guide layer 13 is installed on the upper surface of the reflective layer 12 and serves as the core functional layer of the light guide plate body 1. It is used to receive light input from the side light source and to uniformly guide the light in the plane through the principle of total internal reflection. The light guide layer 13 is preferably made of a transparent material, such as polymethyl methacrylate (PMMA) or polycarbonate (PC), and its surface can be provided with light guide dots or microstructures to optimize light distribution. The diffusion layer 14 is installed on the upper surface of the light guide layer 13 to further scatter the light transmitted by the light guide layer 13, making the output light more uniform and softer, and avoiding excessive local brightness. The diffusion layer 14 can be made of a diffusion film or a transparent plate with a frosted surface.

[0034] Furthermore, the edge of the bottom shell 11 is provided with an extension 111, which extends upward perpendicular to the upper surface of the bottom shell 11 to form a covering structure. The height of the extension 111 is at least matched with the total thickness of the stacked reflective layer 12, light guide layer 13, and diffuser layer 14, thereby covering and fixing the lateral edges of the reflective layer 12, light guide layer 13, and diffuser layer 14 to prevent displacement or separation of the layers during operation. Simultaneously, the inner surface of the extension 111 is provided with a light source mounting position (not shown in the figure) for mounting a light source, such as an LED strip or other suitable side-emitting light source. The light emitted by the light source is directly coupled to the side of the light guide layer 13 through the extension 111 and conducts into the interior of the light guide layer 13. The design of the extension 111 not only enhances the overall structural stability of the light guide plate body 1 but also facilitates the installation and alignment of the light source.

[0035] In this embodiment, the bottom shell 11, reflective layer 12, light guide layer 13, and diffuser layer 14 can be connected by bonding, hot pressing, or mechanical fixing to ensure the compactness and reliability of each layer structure. The extension 111 can be integrally formed with the bottom shell 11, for example, by aluminum plate stamping or bending, or fixedly connected to the bottom shell 11 by welding, riveting, or other methods.

[0036] In this embodiment, the connecting component 2 is used to achieve a detachable connection between the two light guide plate bodies 1, and specifically includes a connecting block 21, a snap-fit ​​component 22, and a mounting shell 23. The connecting block 21 is fixedly installed on the side of one of the light guide plate bodies 1, and the mounting shell 23 is fixedly installed on the corresponding side of the other light guide plate body 1. The snap-fit ​​component 22 is disposed inside the mounting shell 23 and works in cooperation with the connecting block 21 to achieve splicing and fixing of the two light guide plate bodies 1.

[0037] Specifically, the snap-fit ​​assembly 22 includes two snap-fit ​​blocks 221, two connecting rods 222, a mounting base 223, a pull rod 224, a spring 225, a fixing member 226, and a lever 227. The fixing member 226 is fixedly installed inside the mounting housing 23, serving as the supporting base for the snap-fit ​​assembly 22. The pull rod 224 passes through the fixing member 226 along its axial direction and forms a sliding connection with the fixing member 226. One end of the pull rod 224 is fixedly connected to the lever 227. A groove 231 is provided on the outer wall of the mounting housing 23, through which the lever 227 passes and can slide in a predetermined direction within the groove 231. The other end of the pull rod 224, away from the lever 227, is fixedly connected to the mounting base 223, which can move within the mounting housing 23 under the action of the pull rod 224. One end of each of the two connecting rods 222 is rotatably connected to the mounting base 223 via a hinge, and the other end is rotatably connected to each of the two locking blocks 221 via a hinge. Two notches 232 are formed on the side wall of the mounting housing 23, through which the two locking blocks 221 extend and slide to achieve telescopic movement. Each locking block 221 has a guide ramp on its outer end to guide its movement during connection. The spring 225 is sleeved on the pull rod 224, with one end abutting against the mounting base 223 and the other end abutting against the fixing member 226. The spring 225 is in a pre-compressed state, providing elastic restoring force to the mounting base 223.

[0038] The connecting block 21 is provided with a slot 211, the opening size of which is adapted to the shape of the mounting shell 23 to allow the mounting shell 23 to be inserted therein. The inner walls of the slot 211 extend outward on both sides to form receiving portions 212, the position and size of which correspond to the locking block 221, and are used to receive and lock the locking block 221 in the connected state.

[0039] The connection process is as follows: When it is necessary to connect two light guide plate bodies 1, align the mounting shell 23 on one light guide plate body 1 with the connecting block 21 on the other light guide plate body 1, and insert the mounting shell 23 into the slot 211. During the insertion process, the guide slope of the locking block 221 contacts the edge of the slot 211. Under the action of the guide slope, the two locking blocks 221 are subjected to inward pressing force, which drives the connecting rod 222 to rotate and retract inward. At the same time, the mounting base 223 moves along the direction of the pull rod 224 and compresses the spring 225 until the locking blocks 221 are completely retracted into the mounting shell 23. As the insertion action continues, when the locking blocks 221 move to align with the receiving part 212, the elastic restoring force of the spring 225 pushes the mounting base 223 to reset, and then drives the two locking blocks 221 to extend outward and embed into the receiving part 212 through the connecting rod 222. At this time, the mounting shell 23 and the connecting block 21 are locked together, and the sides of the two light guide plate bodies 1 are tightly fitted together, completing the splicing function of the connecting component 2.

[0040] The disassembly process is as follows: When it is necessary to separate the two light guide plate bodies 1, the lever 227 is manually moved, causing it to slide along the slide groove 231 and move the pull rod 224. The pull rod 224 pulls the mounting base 223 towards the fixing member 226, while compressing the spring 225. The movement of the mounting base 223 causes the two locking blocks 221 to retract inward through the connecting rod 222, causing the locking blocks 221 to exit from the receiving part 212 and retract into the mounting shell 23. At this time, the mounting shell 23 is unlocked from the connecting block 21, and the mounting shell 23 can be pulled out from the slot 211, thereby realizing the separation of the two light guide plate bodies 1.

[0041] In this embodiment, the connecting component 2, through the aforementioned structural design, enables the rapid connection and disassembly of the two light guide plate bodies 1. The elastic locking mechanism of the snap-fit ​​component 22 ensures stability in the connected state, while the paddle 227 and pull rod 224 facilitate manual operation, improving ease of use. This design is suitable for portable light guide plate applications requiring frequent assembly and disassembly.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
