[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] Example 1 Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a light guide plate assembly and its attachment method, the light guide plate assembly and its attachment method include a maintenance assembly 200, and the maintenance assembly 200 can solve the problem that the cumbersome disassembly process of the existing light guide plate assembly requires a lot of time and effort.

[0030] The main structure 100 includes a base 101, an inner cavity of the base 101 is provided with a light guide plate assembly body 102, both sides of the light guide plate assembly body 102 are fixedly connected with connecting plates 103, and a transparent key plate 104 is provided on the top of the base 101; and, The maintenance component 200 includes a side plate 201 fixedly connected to both sides of the bottom of the inner cavity of the base 101, a corresponding side of the side plate 201 is fixedly connected to a load-bearing plate 202, a top of the load-bearing plate 202 is provided with a ejector 203, and pads 204 are provided on both sides of the top of the load-bearing plate 202. A block 205 is slidably connected to the side of the side plate 201 close to the load-bearing plate 202, and slots 206 are provided on both sides of the connecting plate 103 and cooperate with the block 205. The side of the block 205 close to the side plate 201 passes through the side plate 201 and is slidably connected to a slide rod 207, which is fixedly connected to the inner cavity of the side plate 201, a limiting member 208 is provided on the top of the block 205, and a separation member 209 is provided at the bottom of the block 205.

[0031] The base 101 serves as a basic carrier and provides installation space for the light guide plate assembly body 102; the design of the connecting plate 103 and the card slot 206 provides a connection basis for the assembly fixation; the light-transmitting key panel 104 ensures that light can be effectively transmitted, and in the maintenance assembly 200, the side panel 201 and the carrier plate 202 constitute a stable supporting structure, and the block 205 and the card slot 206 cooperate to achieve tool-free rapid installation and fixation, replacing the traditional screw connection; the combination of the ejection member 203, the limiting member 208, and the disengagement member 209 are respectively responsible for ejection during disassembly, limiting during installation, and unlocking the fixed state, forming a complete set of rapid disassembly and assembly system, which fundamentally solves the problem of inconvenient installation and disassembly of traditional screw connections.

[0032] Example 2 Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0033] Specifically, the ejector 203 includes a slide 203a fixedly connected to the bottom of the inner cavity of the carrier plate 202, the bottom of the inner cavity of the slide 203a is fixedly connected to the first spring 203b, the top of the first spring 203b is fixedly connected to the ejector tube 203c, the top of the ejector tube 203c passes through the carrier plate 202 and contacts the bottom of the light guide plate assembly body 102.

[0034] Through the structural design of the slide 203a, the first spring 203b and the ejection tube 203c, the automatic ejection function when the light guide plate assembly is disassembled is realized. When the block 205 is disengaged from the slot 206, the elastic restoring force of the first spring 203b pushes the ejection tube 203c to lift the light guide plate assembly body 102 upward, so that maintenance personnel do not need to manually remove the assembly, further simplifying the disassembly process and improving maintenance convenience.

[0035] Specifically, there are multiple groups of the sliding seat 203 a , the first spring 203 b and the ejecting tube 203 c , and they are evenly distributed at the bottom of the light guide plate assembly body 102 .

[0036] The slide seat 203a, the first spring 203b and the ejection tube 203c adopt a multi-group uniform distribution design to ensure that the light guide plate assembly body 102 is evenly stressed when being ejected, avoiding deformation or damage of the assembly due to uneven stress, while ensuring the stability and reliability of the ejection action, providing a good foundation for subsequent disassembly and installation operations.

[0037] Specifically, the limiting member 208 includes a second spring 208 a sleeved on the surface of the sliding rod 207 , and a side of the second spring 208 a away from the clamping block 205 is fixedly connected to the inner cavity of the side plate 201 .

[0038] During the process of engaging the block 205 with the slot 206 , the second spring 208 a provides a continuous elastic support force to firmly engage the block 205 in the slot 206 , thereby preventing the block 205 from loosening due to vibration or external force, and ensuring the connection stability of the light guide plate assembly during use.

[0039] Specifically, the limiting member 208 also includes a limiting ring 208b fixedly connected to the top of the block 205, the inner cavity of the limiting ring 208b is slidably connected to the limiting rod 208c, and the two sides of the limiting rod 208c are respectively fixedly connected to the two sides of the inner cavity of the side plate 201.

[0040] Through the cooperation of the limiting ring 208b and the limiting rod 208c, the moving direction of the block 205 is accurately limited to prevent the block 205 from shifting or tilting during the sliding process, ensuring that the block 205 can be accurately engaged with the slot 206, thereby improving the reliability and stability of the connection structure.

[0041] Specifically, the disengagement member 209 includes a movable plate 209a disposed in the inner cavity of the side plate 201, and both sides of the top of the movable plate 209a are fixedly connected with abutment plates 209b, and the bottom of the block 205 is fixedly connected with a push plate 209b-1, which cooperates with the abutment plate 209b.

[0042] Through the design of the movable plate 209a, the abutment plate 209b and the pushing plate 209b-1, a driving structure is provided for controlling the card block 205 to disengage from the card slot 206. By operating the movable plate 209a, the abutment plate 209b pushes the pushing plate 209b-1, thereby driving the card block 205 to move, thereby achieving a quick unlocking and fixing state, providing a convenient operation method for disassembling the light guide plate assembly.

[0043] Specifically, the disengagement member 209 also includes a toggle plate 209c fixedly connected to the top of the movable plate 209a, the top of the toggle plate 209c passes through the side plate 201 and extends outside the side plate 201, a reset portion 209d is provided on one side of the toggle plate 209c, and the inner cavity of the movable plate 209a is slidably connected to a guide rod 209e, and both sides of the guide rod 209e are respectively fixedly connected to both sides of the inner cavity of the side plate 201.

[0044] The toggle plate 209c is convenient for maintenance personnel to manually operate and control the movable plate 209a; the reset part 209d automatically resets the toggle plate 209c after the operation is completed, and the guide rod 209e guides the movement of the movable plate 209a to ensure the smoothness and stability of the operation and improve the practicality of the overall structure.

[0045] Specifically, the reset portion 209d includes an arc-shaped spring piece 209d-1 in contact with the surface of the toggle plate 209c, and a slider 209d-2 is fixedly connected to the side of the arc-shaped spring piece 209d-1 away from the toggle plate 209c. A sliding groove 209d-3 is provided in the inner cavity of the side plate 201 and cooperates with the slider 209d-2.

[0046] Through the elastic deformation and recovery characteristics of the arc-shaped spring piece 209d-1, combined with the sliding of the slider 209d-2 in the slide groove 209d-3, the automatic resetting function of the toggle plate 209c is realized, making the operation more convenient and efficient, reducing manual operation steps, and improving maintenance efficiency.

[0047] Specifically, the light guide plate assembly body 102 includes a reflective film 102a, a light guide plate body 102b is disposed on the top of the reflective film 102a, a diffusion film 102c is disposed on the top of the light guide plate body 102b, and a brightness enhancement film 102d is disposed on the top of the diffusion film 102c.

[0048] The internal structure of the light guide plate assembly body 102 is clearly defined, and the reflective film 102a, the light guide plate body 102b, the diffusion film 102c and the brightening film 102d are layeredly designed to respectively realize the functions of light reflection, conduction, uniform distribution and enhanced emission effect, thereby providing a high-quality backlight effect for the luminous keyboard and meeting the user's needs for the aesthetics and practicality of the keyboard.

[0049] During the installation process, the light guide plate assembly body 102 together with the connecting plate 103 are placed into the base 101, and the connecting plate 103 contacts the slope on one side of the block 205, pushing the block 205 to slide on the slide rod 207 and compressing the second spring 208a. At the same time, the limiting ring 208b slides on the limiting rod 208c to limit the block 205. When the slot 206 is aligned with the block 205, the second spring 208a pushes the block 205 to snap into the slot 206, completing the fixation of the light guide plate assembly body 102. At this time, the bottom of the light guide plate assembly body 102 contacts the ejection tube 203c, the ejection tube 203c is compressed, and the first spring 203b accumulates force.

[0050] When disassembly is required, the toggle plate 209c is manually moved to drive the movable plate 209a to slide on the guide rod 209e, and the abutment plate 209b pushes the push plate 209b-1 to move the block 205 away from the slot 206, thereby releasing the fixation of the light guide plate assembly body 102. At this time, the first spring 203b releases its elastic potential energy, pushing the ejection tube 203c to eject the light guide plate assembly body 102 upward, making it easier for maintenance personnel to remove the assembly. After the operation is completed, the arc-shaped spring piece 209d-1 restores its deformation, driving the slider 209d-2 to slide in the slide groove 209d-3, so that the toggle plate 209c is reset and prepared for the next operation. This process does not require tools such as screwdrivers. Compared with the traditional screw connection method in the background technology, it greatly simplifies the installation and disassembly process and improves maintenance efficiency.

[0051] Example 3 Reference Figure 8 , which is the third embodiment of the present invention, this embodiment provides a method for attaching a light guide plate assembly, which is implemented based on the light guide plate assembly in any of the above embodiments, and includes the following steps: Step 1: First, use an electrostatic dust removal device to remove dust from the backlight bottom shell and the bottom surface of the light guide plate body 102b, lay the reflective film 102a with the sticky side facing upward on the backlight bottom shell, use a positioning fixture to accurately align the bottom surface of the light guide plate body 102b with the reflective film 102a, generate negative pressure through a vacuum adsorption platform, make the light guide plate body 102b and the reflective film 102a fit tightly, and use a soft rubber roller to roll from the center to the edge of the light guide plate body 102b to remove air; Step 2: Then, a vacuum adsorption platform is used to fix the light guide plate body 102b, and the surface is flattened by vacuum negative pressure. A portion of the protective film of the diffusion film 102c is peeled off, and after aligning with the edge of the light guide plate body 102b, a temperature-adjustable hot pressing roller is used to roll and attach from one end to the other end to reduce the interfacial tension between the diffusion film 102c and the light guide plate body 102b. When the vacuum adsorption platform is used to fix the light guide plate body 102b, it is ensured that the light guide plate body 102b is stable and will not be deformed during the attachment process.

[0052] The surface of the hot pressing roller is coated with an anti-stick coating to prevent the diffusion film 102c from sticking to the hot pressing roller during the rolling process, thereby affecting the attachment effect.

[0053] Step three, finally use the vacuum adsorption platform again to fix the light guide plate body 102b, peel off the protective film of the brightness enhancement film 102d, use the optical alignment system to accurately align the brightness enhancement film 102d with the light guide plate body 102b and the diffusion film 102c, use a pneumatic pressure head with uniform pressure to perform preliminary pressing, and then use ultraviolet curing glue to seal the edge of the brightness enhancement film 102d, and cure it through an ultraviolet irradiation device to prevent the edge of the brightness enhancement film 102d from warping and dust from entering.

[0054] The surface of the pneumatic pressure head is covered with an elastic silicone pad to ensure that the pressure applied to the brightness enhancement film 102d is uniform and avoids indentation.

[0055] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
