Abstract
Description
Technical Field
[0001] This utility model relates to vehicle-mounted equipment structures, and in particular to a waterproof integrated shell structure for vehicle-mounted equipment used in medium-sized industrial and agricultural electronic products. Background Technology
[0002] The entire vehicle-mounted tablet typically relies on the foam adhesive of the front shell to fix and seal the screen. The waterproof ring is first assembled on the back shell, and then the back shell is fixed on the front shell. The waterproof ring is sealed and waterproof by compressing the front shell and the back shell.
[0003] The assembly process is quite complex, and the multiple waterproof sealing structures will affect the overall waterproof sealing yield. The two-piece design of the front and back shells will increase the overall thickness, and correspondingly, there will be an additional assembly gap between the front and back shells, which will seriously affect the overall aesthetics of the machine. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides an integrated waterproof structure for vehicle-mounted equipment. All components are fixedly installed in one shell, and the entire machine is waterproofed and sealed only at the screen, which improves the waterproof sealing yield. The integrated shell structure reduces the overall thickness of the machine, eliminates assembly gaps, and improves the overall aesthetics.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A waterproof integrated shell structure for vehicle-mounted equipment mainly consists of a shell assembly, a display screen assembly, screen foam adhesive, and a motherboard assembly.
[0007] The screen foam adhesive is located above the housing assembly and is assembled onto the housing assembly by means of the screen foam adhesive's four-sided positioning and is fixed by the adhesive on the screen foam adhesive itself.
[0008] The motherboard assembly is located above the housing assembly and is fixed to the housing assembly with screws.
[0009] The display screen assembly is located above the housing assembly. It is assembled onto the housing assembly by limiting the four sides of the display screen assembly and is fixed onto the housing assembly by screen foam adhesive.
[0010] Furthermore, the display assembly and the housing assembly are sealed with foam adhesive, reducing the number of waterproof sealing paths and improving the overall yield rate.
[0011] Furthermore, the display assembly is enclosed and protected by a housing assembly, thereby increasing the screen's shock absorption effect.
[0012] Furthermore, the entire vehicle-mounted device is secured to the motherboard assembly and the display screen assembly via a housing assembly, forming a seamless whole and improving the overall aesthetics.
[0013] The beneficial effects of this utility model are:
[0014] This invention optimizes the BOM cost of structural components, reduces the amount of material used in the main shell, and improves efficiency. The reduced sealing paths improve the overall waterproofing yield. The optimized assembly process increases production efficiency. The unibody structure reduces the overall thickness of the machine, eliminating assembly gaps and enhancing its aesthetics. Attached Figure Description
[0015] The technical solution and beneficial effects of this utility model will become apparent from the following detailed description of specific embodiments in conjunction with the accompanying drawings.
[0016] Figure 1 This is the assembly diagram of the complete machine of this utility model.
[0017] Figure 2 This is a schematic diagram of the overall structure of this utility model.
[0018] Figure 3 This is a schematic diagram of the plastic back cover of this utility model.
[0019] Figure 4 This is a partial sectional view of the overall structure of this utility model.
[0020] The main components shown in the diagram are: display module 100, screen foam adhesive 200, motherboard assembly 300, and housing assembly 400.
[0021] Description of housing assembly 400: housing frame 410, housing screen foam adhesive table 420, housing inner wall 430. Detailed Implementation
[0022] 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.
[0023] like Figures 1 to 2 As shown, the assembly process is as follows: 1. First, assemble the motherboard assembly 300 onto the housing assembly 400 and tighten the screws to secure it.
[0024] 2. Then assemble the screen foam adhesive 200 onto the housing assembly 400, and hold the pressure for 10 seconds.
[0025] 3. Finally, assemble the display module 100 onto the housing assembly 400, and hold the pressure in the fixture for 15 seconds to complete the overall assembly of the vehicle-mounted tablet 001.
[0026] like Figures 2 to 4 As shown, the screen foam adhesive position 200 is above the housing assembly 400 and is assembled by being limited by the housing frame 410.
[0027] The display screen assembly 100 is located above the housing assembly 400, is limited by the housing frame 410, and is bonded and fixed to the housing screen foam adhesive table 420 by screen foam adhesive 200.
[0028] The display assembly 100 and the housing assembly 400 are sealed with screen foam adhesive 200, which reduces the waterproof sealing path and improves the overall yield.
[0029] The display screen assembly 100 is enclosed and protected by the housing assembly 400, thereby increasing the screen's shock absorption effect.
[0030] The entire machine is secured to the motherboard assembly 300 and the display assembly 100 by the housing assembly 400, forming a seamless whole and improving the overall aesthetics.
[0031] The inner wall position 430 on the rear shell assembly 400 improves the problem of plastic thickness on the side of the plastic shell, makes the overall thickness of the plastic rear shell uniform, solves the problem of stress concentration in injection molding, and optimizes the problem of uneven thickness on the side of the plastic rear shell.
[0032] The integrated shell assembly 400 optimizes the BOM cost of structural components by reducing the amount of material needed for the outer shell structure.
[0033] like Figure 2 As shown, the only sealing path for the entire machine is the mating position between the screen assembly 100 and the housing assembly 400, reducing the number of sealing paths and improving the overall waterproof yield. Optimizing the overall assembly process also increases production efficiency.
[0034] 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.
