Abstract
Description
Technical Field
[0001] This utility model relates to vehicle-mounted tablet structures, and more particularly to a waterproof structure for a full-screen multi-functional button system used in medium-sized industrial and agricultural electronic products. Background Technology
[0002] Currently, the buttons on the full-screen tablets in agricultural machinery are mainly located on the heat dissipation surface and have relatively limited functions. However, agricultural machinery operates in harsh environments, and rain and sandstorms can affect the screen display. In such situations, the buttons are in blind spots, making it difficult for the driver to touch the tablet's button functions and increasing the risk of misjudgment during operation.
[0003] Traditional agricultural machinery vehicle-mounted tablet screens have relatively large buttons that are scattered, which seriously affects the overall structural stacking layout and makes the appearance bulky. Summary of the Invention
[0004] To address the aforementioned technical problems, this utility model provides a waterproof structure for a multi-functional button on a vehicle-mounted full-screen display, resolving the issue of misjudgment of touch input on the full-screen button of vehicle-mounted devices, and also providing an alternative solution for screen touch operation in harsh working environments.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A waterproof structure for a vehicle-mounted full-screen multi-functional button is mainly composed of a display module, a front shell assembly, a button assembly, a motherboard assembly, and a rear shell assembly.
[0007] The button assembly is located below the front cover assembly and is assembled with the button caps and button holes on the front cover assembly.
[0008] The button assembly includes a button, a button bracket, and a button FPC.
[0009] The key comprises keycaps and TPU soft rubber, and the six keycaps and TPU soft rubber are integrally molded by double-shot injection molding.
[0010] The button bracket is located below the button assembly, and is assembled by positioning posts on the faceplate assembly and fixed by screws.
[0011] The button FPC is assembled by positioning posts on the button bracket and fixed to the button bracket by screws.
[0012] The motherboard assembly is located above the rear shell assembly and is secured with screws.
[0013] The button position on the upper right side of the front panel assembly is designed with a large bevel transition, and the keycaps do not protrude above the screen to avoid accidental touches caused by frontal collisions of the entire device.
[0014] Furthermore, the display module is located above the faceplate assembly and is fixed and sealed by foam adhesive.
[0015] Furthermore, the button FPC is connected to the motherboard via a spring contact to achieve function signal transmission.
[0016] Furthermore, the button assembly is located on the right side of the screen, with six function keycaps distributed between the three screw posts on the right side of the front panel assembly, thereby reducing the overall width of the device.
[0017] Furthermore, the button contacts the faceplate assembly via TPU soft rubber, and is sealed and waterproof by pressing the TPU soft rubber together with the button bracket.
[0018] Furthermore, the TPU soft adhesive creates separate sealing compartments at the locations of the six function buttons, sealing each function button individually.
[0019] Furthermore, the seven screw holes on the button bracket are evenly distributed on both sides of the button, thereby forming a pressing plane to provide Z-axis pressure for each function button and improve the stability of waterproof sealing.
[0020] The beneficial effects of this utility model are:
[0021] This invention features buttons located on the right side of the screen, resulting in a small footprint and minimal impact on the overall aesthetics of the full-screen display. The full-screen button structure facilitates manual operation for the driver, reducing reliance on the touchscreen and comprehensively enhancing the user experience. The button caps are angled and lower than the screen to prevent accidental touches from direct impact. Each of the six buttons is individually sealed, improving their waterproof sealing reliability.

[0032] Motherboard component 400 description: Motherboard button spring 410. Detailed Implementation
[0033] 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. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0034] like Figures 1 to 2 As shown, the assembly process is as follows: First, assemble the display module 100 onto the front shell assembly 200, holding the pressure in the fixture for 15 seconds. Then, install the button assembly 300 onto the front shell assembly 200 and secure it with screws. Next, install the motherboard assembly 400 onto the rear shell assembly 500 and secure it with screws. Finally, assemble the front shell assembly 200, with the button assembly 300 and display module installed, onto the rear shell assembly 500 and secure it with screws. This completes the overall assembly of the vehicle-mounted tablet 001.
[0035] like Figure 4 As shown, six keycaps 311 and key TPU soft rubber 312 are integrally molded by double-color injection molding to form a complete component key 310.
[0036] like Figures 2 to 6 As shown, button 310 is assembled with button hole of face shell assembly 200 by button cap 311 and fixed by button bracket 320. Button bracket 320 is locked to face shell button bracket screw post 230 by screw passing through button bracket screw hole 321.
[0037] like Figures 2 to 6As shown, the button FPC 330 is assembled and positioned by the positioning posts of the button bracket 320, and is locked onto the button bracket FPC screw posts 323 by screws passing through the button FPC screw holes 333. The button FPC interface 332 is fixed to the front cover button FPC fixing slot 240 by its shape and adhesive backing.
[0038] like Figures 2 to 6 As shown, the button FPC interface 332 is connected to the motherboard button spring 410 on the motherboard assembly 400 to realize signal transmission. The button FPC relies on the button mechanism 331 to provide mechanical function for the button 310, while also providing support to prevent it from sinking when pressed.
[0039] like Figures 2 to 6 As shown, the button assembly 300 is located on the right side of the display module 100, and the six button caps 311 are distributed in the middle of the three face shell button bracket screw posts 230 on the right side of the face shell assembly 200. The structure is compact, thereby reducing the proportion of the width of the whole machine.
[0040] like Figure 6 As shown, the button 310 on the right side of the front panel assembly 200 has a large bevel transition, and the button cap 311 does not protrude from the screen to avoid accidental touches caused by front collisions of the entire device.
[0041] like Figures 2 to 6 As shown, button 310 contacts the button sealing surface 220 of the front shell through button TPU soft rubber 312, and relies on button bracket 320 to press button TPU soft rubber 312 to seal and waterproof.
[0042] like Figures 2 to 6 As shown, the TPU soft rubber 312 on the buttons creates a separate sealing chamber at the position of the 6 keycaps 311, sealing each function key individually.
[0043] like Figures 2 to 6 As shown, the button bracket 320 is evenly distributed on the left and right sides of the button 310 through 7 screw holes, thereby forming a pressing plane to provide Z-axis pressure for each function button keycap 311 and improve waterproof sealing stability.
[0044] 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.
