Description

Technical Field

[0001] This utility model relates to the field of backlight modules, specifically a backlight module that is easy to assemble and disassemble. Background Technology

[0002] The backlight module is a core component of an LCD display. Its core function is to provide a uniform and sufficient light source for the non-light-emitting panel to ensure clear image display. Its specific working principle is to use the principle of total internal reflection to propagate within the panel. When the light encounters the dots on the bottom surface, the total internal reflection condition is broken, and the light is refracted upward and penetrates the diffusion film and the brightness enhancement film, ultimately forming a uniform surface light source.

[0003] In current installations, backlight modules are placed within a frame, and sealant is typically applied between the module and the frame to ensure overall sealing. This not only secures the module but also prevents dust and impurities from entering. However, this method requires removing the sealant for maintenance, which is labor-intensive and resource-intensive. Furthermore, the backlight module generates significant heat during operation, and the sealed design makes it difficult to dissipate this heat effectively, potentially impacting its lifespan over time.

[0004] In conclusion, the above installation method is too wasteful of manpower and resources during subsequent disassembly, and the backlight module generates a lot of heat when it is working. Under sealed conditions, it is difficult to effectively dissipate the internal heat, which will affect the service life of the backlight module over a long period of time. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a backlight module that is easy to disassemble and assemble, so as to solve the technical problems that subsequent disassembly is too wasteful of manpower and resources, and that the backlight module generates a lot of heat when it is working, and the internal heat is difficult to be effectively dissipated in the sealed state, which will affect the service life of the backlight module for a long time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a backlight module that is easy to assemble and disassemble, comprising a frame, an array of concave plates elastically slidably disposed on the inner side of the frame, and a wedge block disposed at the bottom of the concave plates within the frame, a sealing plate slidably disposed within the wedge block, an array of heat-conducting columns sleeved on the sealing plate, and a top rod slidably disposed within the interlayer of the frame, which cooperates with the sealing plate, and the top rod is used to drive the concave plates to slide in the horizontal direction.

[0007] By adopting the above technical solution, the heat-conducting column is squeezed by the mounting surface, causing the sealing plate to slide to one side. During this process, the push rod will slide upward and squeeze the sliding guide column on one side, so that the sliding guide column pushes the concave plate to limit and clamp the side wall of the backlight module. After the frame is installed, the backlight module is limited and clamped. This process speeds up the overall installation efficiency. The heat-conducting column will contact the back end of the backlight module, and the other end of the guide column will contact the mounting surface. During the operation of the backlight module, the heat generated will be transferred to the mounting surface through the heat-conducting column, thereby completing the heat dissipation of the backlight module.

[0008] The present invention is further configured such that a sliding guide post is provided at one end of the concave plate, wherein one end of the sliding guide post is in contact with one end of the top rod.

[0009] Preferably, during the movement of the push rod through the sealing plate, the push rod will press against one end of the sliding guide post. During this process, the sliding guide post will drive the concave plate to move to one side, thereby completing the limiting and clamping work of the backlight module during the installation process.

[0010] The present invention is further configured such that a side plate is provided on one side of the sealing plate within the wedge-shaped block, wherein the top of the side plate is connected to the top rod.

[0011] Preferably, the sealing plate slides within the wedge block under the action of the heat-conducting column. During the sliding process, it drives the side plate at one end to move, thereby driving the top rod at the top to move.

[0012] The present invention is further configured such that a groove for sliding of the sealing plate is provided in the wedge-shaped block, and an elastic component is installed in the groove, one end of which is connected to the sealing plate.

[0013] Preferably, the groove is designed to allow the sealing plate to move within the wedge during the movement of the heat-conducting column. During this process, the sealing plate itself will squeeze the elastic component, causing the elastic component to be in a compressed state. Subsequently, when the frame is disassembled, the sealing plate will be reset and slid by the reset action of the elastic component.

[0014] The present invention is further configured such that the concave plate is narrower at the top and wider at the bottom, and a protective sleeve is provided on the inner wall of the concave plate, and the protective sleeve itself is detachable.

[0015] Preferably, the top-narrow and bottom-wide design makes it easy for staff to place the backlight module inside the concave plate without the need for snapping, effectively preventing wear on the backlight module during installation. Furthermore, the internal protective sleeve prevents wear on the edges of the backlight module when the concave plate slides inward.

[0016] The present invention is further configured such that the frame is provided with an array of threaded holes that cooperate with bolt assemblies.

[0017] Preferably, the presence of threaded holes facilitates the installation of the frame in the designated location by workers using bolt assemblies, thereby improving the overall installation efficiency of the frame.

[0018] The present invention is further provided that the side wall of the sealing plate is provided with a sealing sleeve, and the sealing sleeve is slidably located on the inner wall of the frame.

[0019] Preferably, the sealing sleeve ensures that one side of the backlight module is in a sealed area during the movement of the sealing plate within the groove, thus preventing impurities in the air from entering during the operation of the backlight module.

[0020] The present invention is further provided that both ends of the heat-conducting column are provided with heat-conducting rubber.

[0021] Preferably, the thermally conductive rubber itself is flexible, which ensures that one end of the thermally conductive pillar makes full contact with the mounting surface when facing a relatively uneven mounting surface, thereby improving the heat dissipation effect of the thermally conductive pillar on the backlight module.

[0022] The present invention is further configured such that one end of both the sliding guide post and the top rod is provided with an arc-shaped end face, and the arc-shaped end face itself is smooth.

[0023] Preferably, the arc-shaped end face helps to prevent jamming between the sliding guide post and one end of the push rod during the movement of the sliding guide post, and the smooth shape can reduce the sliding friction between the two.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model features a sealing plate elastically set within a wedge-shaped block. The backlight module is placed on one side of the sealing plate. During installation, the sealing plate slides to one side by pressing the heat-conducting column against the mounting surface. During this process, the push rod slides upward and presses against the sliding guide column on one side, causing the sliding guide column to push the concave plate to limit and clamp the side wall of the backlight module. After the frame is installed, the backlight module is clamped and limited. This process speeds up the overall installation efficiency. Furthermore, when maintaining the backlight module, only the frame itself needs to be disassembled to reset the push rod, thereby releasing the concave plate from limiting the side wall of the backlight module. This saves a lot of manpower and resources and improves disassembly efficiency.

[0026] 2. This utility model has an array of heat-conducting columns on the sealing plate. During installation, the mounting surface will press the heat-conducting columns, causing the heat-conducting columns to slide the sealing plate inward. During this process, the heat-conducting columns will come into contact with the back end of the backlight module, and the other end of the heat-conducting column will come into contact with the mounting surface. During the operation of the backlight module, the heat generated will be transferred to the mounting surface through the heat-conducting columns, thereby completing the heat dissipation of the backlight module and effectively preventing heat accumulation.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1: Please refer to Figures 1-6The backlight module shown includes a frame 1, a concave plate 2, a limiting mechanism, a sliding mechanism, and a heat dissipation mechanism. The frame 1 has a series of threaded holes that mate with bolt assemblies, allowing workers to install the frame 1 at a designated position using the bolt assemblies. An array of concave plates 2 are elastically slidably disposed on the inner side of the frame 1. Workers place the backlight module on the concave plates 2 and then install the frame 1. A wedge-shaped block 5 is located at the bottom of the concave plate 2 within the frame 1, and a sealing plate 3 is slidably disposed within the wedge-shaped block 5. An array of heat-conducting columns 4 are fitted onto the sealing plate 3. Normally, the heat-conducting columns 4 protrude from the back end of the frame 1. During installation, the heat-conducting columns 4 contact the mounting surface, causing the sealing plate 3 to slide. A push rod 10 that mates with the sealing plate 3 is slidably disposed within the interlayer of the frame 1.

[0038] One end of the concave plate 2 is provided with a sliding guide post 9, one end of which is in contact with one end of the push rod 10. During the movement of the push rod 10 through the sealing plate 3, the push rod will press one end of the sliding guide post 9. During this process, the sliding guide post 9 will drive the concave plate 2 to move to one side, thereby completing the limiting and clamping work of the backlight module during the installation process. After the installation is completed, the heat-conducting column 4 will contact the back end of the backlight module, and the other end of the heat-conducting column 4 will contact the mounting surface. During the operation of the backlight module, the heat generated will be transferred to the mounting surface through the heat-conducting column 4, thereby completing the heat dissipation work of the backlight module.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A side plate 8 is provided on one side of the sealing plate 3 within the wedge block 5. The top of the side plate 8 is connected to the top rod 10. The sealing plate 3 itself slides within the wedge block 5 under the action of the heat-conducting column 4. During the sliding process, it will drive the side plate 8 at one end to move, thereby driving the top rod 10 at the top to move.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The concave plate 2 is narrower at the top and wider at the bottom, and a protective sleeve is provided on the inner wall of the concave plate 2. The protective sleeve is detachable. The narrower at the top and wider at the bottom design makes it easy for the staff to place the backlight module inside the concave plate 2 without the need for snapping. This effectively prevents the backlight module from being worn during installation. In addition, when the concave plate 2 slides inward, the protective sleeve can prevent wear on the edges of the backlight module.

[0041] Example 2: Please refer to Figure 3 and Figure 4The backlight module shown is easy to assemble and disassemble. Its overall structure is similar to that of Embodiment 1. The wedge block 5 has a groove 7 for sliding the sealing plate 3. An elastic component 6 is installed in the groove 7. One end of the elastic component 6 is connected to the sealing plate 3. The groove 7 is designed to allow the sealing plate 3 to move within the wedge block 5 during the movement of the heat-conducting column 4. During this process, the sealing plate 3 will squeeze the elastic component 6, so that the elastic component 6 is in a compressed state. Then, when the frame 1 is disassembled, the sealing plate 3 is reset and slid by the reset action of the elastic component 6, thereby cooperating with the push rod 10 to complete the disassembly of the backlight module.

[0042] In practical operation, this invention works as follows: The backlight module is placed inside the frame 1, with its back end resting on the concave plate 2. During installation, the back end of the frame 1 contacts the mounting surface, causing the mounting surface to press against the heat-conducting column 4 inside the frame 1. This heat-conducting column 4 then causes the sealing plate 3 on the outer wall to slide inwards, bringing one end of the heat-conducting column 4 into contact with the back end of the backlight module. Simultaneously, as the sealing plate 3 slides, the push rod 10 within its wedge-shaped block 5 moves upwards, thereby causing the push rod 10... The sliding guide post 9 at the top is squeezed. During this process, the sliding guide post 9 will drive the concave plate 2 to move inward. Thus, the concave plate 2 completes the limiting and clamping work of the backlight module. There is no need for manual secondary fixation with bolts or sealant, which saves a lot of manpower and resources and facilitates subsequent disassembly. Furthermore, the two ends of the heat-conducting post 4 are in contact with the backlight module and the mounting surface, respectively. When the backlight module is working, the heat generated by it will be transferred to the mounting surface through the heat-conducting post 4, thereby completing the heat dissipation of the backlight module.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
