Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a liquid crystal module diffuser plate. Background Technology

[0002] As a core component of display devices, the LCD module's diffuser plate plays a crucial role in uniformly scattering light and improving the consistency of the displayed image. It is widely used in terminal products such as LCD monitors, televisions, and touch screens. To ensure the optical performance and structural stability of the diffuser plate, the module is typically equipped with a protective structure consisting of a front frame and a rear frame. The front frame fixes the display body, while the rear frame supports the diffuser plate. The reliability of the connection between the two directly affects the module's assembly efficiency and ease of subsequent maintenance.

[0003] Existing LCD module diffuser plates have been found to have the following issues during use:

[0004] 1. Existing frame connections mostly use bolt fastening or clip-on bolt combination, which makes the installation and disassembly process cumbersome and cannot be quickly aligned for disassembly, resulting in poor practicality.

[0005] 2. The existing frame relies on specialized tools. Bolted connections require the use of tools such as screwdrivers. If the tools are missing or the specifications are not compatible, it will directly hinder the disassembly and assembly work, increasing maintenance costs and time costs. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a liquid crystal module diffuser plate to solve the technical problems mentioned in the background art, such as the cumbersome installation and disassembly process and the need for specific tools for disassembly.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a liquid crystal module diffuser plate, comprising a display body, a front frame disposed on the outer side of the display body, a connecting mechanism disposed at the rear end of the frame, a rear frame disposed at the rear end of the frame via the connecting mechanism, a diffuser plate disposed within the rear frame, the front end of the diffuser plate being connected to the rear end of the display body, the connecting mechanism comprising four sets of positioning blocks, grooves disposed at both ends of the inner side of the front frame, and positioning blocks being fitted at the top and bottom of the inner sides of the two sets of grooves, sliding components disposed on both sides of the front end of the rear frame, and connecting plates being slidably disposed on both sides of the front end of the rear frame via the sliding components, one end of the two sets of connecting plates being evenly connected to the other end of the two sets of positioning blocks, and a slope disposed on the front side of one end of each of the four sets of positioning blocks, a pressing component disposed in the central area of ​​the two sets of grooves, and an auxiliary component disposed on the outer side of the connection between the front frame and the rear frame.

[0010] This utility model is further configured such that the sliding assembly includes four sets of connecting springs, two sets of sliding grooves are respectively provided on both sides of the front end of the rear frame, sliding rods are provided on the inner side of each of the four sets of rear frame sliding grooves, and sliders are slidably provided on the outer side of each of the four sets of sliding rods. The four sets of sliders are slidably connected to the corresponding rear frame sliding grooves. Connecting springs are fitted on opposite sides of the outer side of each of the four sets of sliding rods. The two ends of the four sets of connecting springs are respectively connected to one end of the corresponding rear frame sliding groove and one end of the slider. The top and bottom of the rear ends of the two sets of connecting plates are respectively connected to the front end of a set of sliders. The sliding cooperation between the sliding rods and the sliders provides stable guidance for the connecting plates, ensuring that the force is balanced when the positioning block is engaged, avoiding unstable engagement due to offset. The elastic reset function of the connecting springs enables the positioning block to retract automatically, reducing manual operation steps and solving the cumbersome problem of manually prying open the traditional buckle structure. The symmetrical distribution of the four sets of connecting springs and sliders makes the connecting plates evenly stressed, and the positioning block fits tightly with the groove, improving the shock resistance of the frame connection and adapting to the vibration environment during transportation or use.

[0011] The present invention is further configured such that the extrusion assembly includes an extrusion block, and an extrusion block is slidably disposed in the central area of ​​each of the two sets of grooves. A reserved hole is provided at one end of each of the two sets of grooves, and a connecting rod is slidably disposed in the reserved hole of each of the two sets of grooves. One end of each of the two sets of connecting rods is connected to one end of the extrusion block. Through the cooperation of the connecting rod and the extrusion block, a concentrated thrust is provided to make the positioning block quickly disengage from the groove, replacing the traditional manual prying and pulling buckle method, solving the problem of laborious disassembly. The sliding design of the extrusion block ensures that the thrust is evenly applied to the connecting plate. It can be operated without special tools, further improving the convenience of disassembly, and is especially suitable for maintenance work in the narrow space of the LCD module.

[0012] The present invention is further configured such that the auxiliary component includes two sets of mounting brackets, each set of mounting brackets having a U-shaped groove at one end. The top and bottom of the front frame are respectively connected to the inner front end of one set of U-shaped grooves, and the top and bottom front ends of the rear frame are respectively in close contact with the inner rear end of the corresponding U-shaped grooves. The U-shaped grooves of the mounting brackets provide precise positioning for frame docking, solving the docking misalignment problem that is prone to occur in traditional unsupported structures, ensuring that the diffuser plate fits tightly with the display body, ensuring uniform light scattering, and the wrapping of the frame edges by the U-shaped grooves enhances the rigidity of the overall structure, reduces deformation during long-term use, and improves dustproof performance.

[0013] The present invention is further configured such that threaded holes are provided through one end of the rear frame at the left and right ends of the two sets of mounting brackets, and positioning screws are threadedly connected to the corresponding threaded holes of the rear frame at the inner sides of the threaded holes of the four sets of mounting brackets; the cooperation between the positioning screws and the threaded holes further strengthens the connection between the mounting brackets and the frame, and prevents the U-shaped groove from loosening due to vibration.

[0014] The present invention is further provided that each of the two sets of connecting rods is provided with a pressing handle at one end; the pressing handle increases the force application radius of the connecting rod, so that the operator does not need to directly press the smooth connecting rod, making the force application more effortless.

[0015] The present invention is further configured such that each of the four sets of positioning screws is provided with a rotating handle at one end; the rotating handle provides a convenient force application point for the positioning screw, and reduces the force required for rotation through the lever principle.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a liquid crystal module diffuser plate, which has the following beneficial effects:

[0018] 1. By using the snap-fit ​​mechanism of the positioning block and the groove, the traditional bolt connection is replaced, enabling rapid assembly of the front and rear frames and solving the problem of cumbersome installation and disassembly. The beveled design of the positioning block reduces the difficulty of snap-fit ​​alignment and improves assembly efficiency. The sliding component and the pressing component work together to complete disassembly without special tools, breaking the dependence on bolt tools. The auxiliary components enhance the tightness of the frame connection and prevent the diffuser plate from affecting the optical performance due to loosening. The overall structure takes into account both convenience and stability and is suitable for the high-frequency maintenance needs of LCD modules.

[0019] 2. The sliding engagement of the slide bar and slider provides stable guidance for the connecting plate, ensuring balanced force during positioning block installation and preventing unstable engagement due to misalignment. The elastic reset function of the connecting spring enables automatic retraction of the positioning block, reducing manual operation steps and solving the cumbersome problem of manually prying open traditional snap-fit ​​structures. The symmetrical distribution of four sets of connecting springs and sliders ensures uniform force on the connecting plate, a tight fit between the positioning block and the groove, and improved shock resistance of the frame connection, adapting to vibration environments during transportation or use.

[0020] 3. The connection rod and the extrusion block work together to provide concentrated thrust, which makes the positioning block quickly disengage from the groove, replacing the traditional manual prying and pulling buckle method. This solves the problem of laborious disassembly. The sliding design of the extrusion block ensures that the thrust is evenly applied to the connecting plate. No special tools are required for operation, which further improves the convenience of disassembly. It is especially suitable for maintenance work in the narrow space of the LCD module.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] Please see Figure 1-5 A liquid crystal module diffuser plate includes a display body 1, a front frame 2 on the outer side of the display body 1, a connecting mechanism at the rear end of the frame, a rear frame 3 at the rear end of the frame via the connecting mechanism, a diffuser plate 4 inside the rear frame 3, the front end of the diffuser plate 4 being connected to the rear end of the display body 1, the connecting mechanism including four sets of positioning blocks 6, grooves 5 at both ends of the inner side of the front frame 2, and positioning blocks 6 being snapped into the top and bottom of the inner sides of the two sets of grooves 5, sliding components on both sides of the front end of the rear frame 3, and connecting plates 7 slidingly mounted on both sides of the front end of the rear frame 3 via the sliding components, one end of the two sets of connecting plates 7 being evenly connected to the other end of the two sets of positioning blocks 6, and a slope 8 on the front side of one end of each of the four sets of positioning blocks 6, a pressing component in the central area of ​​the two sets of grooves 5, and an auxiliary component on the outer side of the connection between the front frame 2 and the rear frame 3.

[0031] In this embodiment, during assembly, the front frame 2 and the rear frame 3 on the outer side of the display body 1 are connected by a connecting mechanism. The front end of the diffuser plate 4 inside the rear frame 3 is attached to the rear end of the display body 1. The grooves 5 on the left and right ends of the inner side of the front frame 2 provide a space for the positioning blocks 6 to be fitted. The sliding components on both sides of the front end of the rear frame 3 drive the connecting plate 7 to move. The connecting plate 7 pushes the four sets of positioning blocks 6 to be embedded in the top and bottom of the groove 5. The positioning blocks 6 are guided into place by the inclined surface 8 on the front side, thus achieving the initial fixation of the front frame 2 and the rear frame 3. During disassembly, the squeezing component in the groove 5 pushes the connecting plate 7, causing the connecting plate 7 to drive the positioning blocks 6 to disengage from the groove 5. The sliding component drives the connecting plate 7 to reset, so that the positioning blocks 6 are retracted into the rear frame 3. At the same time, the auxiliary component enhances the sealing and stability of the connection between the front and rear frames 3.

[0032] More specifically, when the front and rear frames 3 are connected, the U-shaped grooves 15 of the two sets of mounting brackets 14 are respectively engaged at the top and bottom of the front frame 2, and the front ends of the top and bottom of the rear frame 3 are tightly attached to the inner rear end of the U-shaped groove 15. The connection angle of the front and rear frames 3 is corrected by the limiting effect of the U-shaped groove 15 to prevent lateral displacement. Then, the four sets of positioning screws 16 are screwed into the threaded holes through which the mounting bracket 14 and the rear frame 3 pass. The threaded engagement makes the U-shaped groove 15 of the mounting bracket 14 tightly attached to the front and rear frames 3, thereby increasing the connection pressure.

[0033] Please see Figure 1 and Figure 4 As one implementation of the sliding component: the sliding component includes four sets of connecting springs 9, two sets of sliding grooves are respectively provided on both sides of the front end of the rear frame 3, and sliding rods 10 are provided on the inner side of each of the four sets of sliding grooves of the rear frame 3. Sliding blocks 11 are slidably provided on the outer side of each of the four sets of sliding rods 10, and the four sets of sliding blocks 11 are slidably connected to the corresponding sliding grooves of the rear frame 3. Connecting springs 9 are fitted on opposite sides of the outer side of each of the four sets of sliding rods 10. The two ends of the four sets of connecting springs 9 are respectively connected to one end of the corresponding sliding groove of the rear frame 3 and one end of the sliding block 11. The top and bottom of the rear ends of the two sets of connecting plates 7 are respectively connected to the front end of one set of sliding blocks 11.

[0034] Specifically, when the front frame 2 and the rear frame 3 are connected, the slider 11 in the sliding grooves on both sides of the front end of the rear frame 3 slides along the sliding rod 10, which drives the connecting plate 7 to move. The connecting plate 7 pushes the positioning block 6 to embed into the groove 5 of the front frame 2. During the movement of the slider 11, the connecting spring 9 on the outside of the sliding rod 10 is compressed and stores elastic potential energy. The positioning block 6 is embedded in the groove 5 of the front frame 2 to complete the fixation.

[0035] Please refer to Figures 2-4 As a further embodiment of the extrusion assembly: the extrusion assembly includes an extrusion block 12, and the extrusion block 12 is slidably disposed in the central area of ​​the two sets of grooves 5 respectively. A reserved hole is provided at one end of each of the two sets of grooves 5. A connecting rod 13 is slidably disposed in the reserved hole of each of the two sets of grooves 5, and one end of each of the two sets of connecting rods 13 is connected to one end of the extrusion block 12 respectively.

[0036] Specifically, when disassembling the frame, push the connecting rod 13 in the pre-drilled hole of the groove 5. The connecting rod 13 causes the pressing block 12 in the central area of ​​the groove 5 to slide. The pressing block 12 contacts the connecting plate 7 and applies a pushing force, causing the positioning block 6 to overcome the elasticity of the sliding component and disengage from the groove 5 of the front frame 2. At this time, the worker can pull the front frame 2 to complete the disassembly.

[0037] In summary, the overall equipment is in use (or running):

[0038] During installation, place the front end of the rear frame 3 close to the rear end of the front frame 2. The slider 11 in the groove of the rear frame 3 slides along the slide rod 10, which drives the connecting plate 7 to push the positioning block 6 forward. The positioning block 6 is guided by the inclined surface 8 and inserted into the top and bottom of the inner groove 5 of the front frame 2. The connecting spring 9 is compressed. At the same time, the U-shaped groove 15 of the mounting bracket 14 is engaged with the top and bottom of the front frame 2. The front ends of the top and bottom of the rear frame 3 are in close contact with the inner rear end of the U-shaped groove 15. Hold the rotating handle 18 and tighten the positioning screw 16 to fix the mounting bracket 14 to the rear frame 3, thus completing the overall installation.

[0039] During disassembly, rotate the handle 18 in the opposite direction. The positioning screw 16 disengages from the threaded hole of the mounting bracket 14 and the rear frame 3. Remove the mounting bracket 14, grasp the pressing handle 17 and push the connecting rod 13. The connecting rod 13 causes the pressing block 12 in the groove 5 to slide. The pressing block 12 pushes the connecting plate 7, causing the connecting plate 7 to drive the positioning block 6 out of the groove 5. The connecting spring 9 pulls the slider 11 to reset along the sliding rod 10. The slider 11 drives the connecting plate 7 and the positioning block 6 to retract into the rear frame 3, separating the front frame 2 and the rear frame 3, thus completing the disassembly.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
