Description

Technical Field

[0001] This utility model relates to the field of automotive instrument technology, specifically a simple and efficient full LCD instrument mounting structure. Background Technology

[0002] In existing technologies, the display screen (such as an LCD screen) of a full LCD instrument panel and the protective glass (such as tempered glass or plexiglass) are usually fixed and bonded by adhesive filling. This process is costly, as adhesive filling requires special adhesives, high-precision adhesive application equipment, and curing processes. Not only are the raw material costs high, but additional equipment purchase and maintenance costs are also required, leading to an increase in the overall production and manufacturing costs. Moreover, replacement is inconvenient. After the adhesive cures, the display screen and the protective glass form an integrated structure. When any part (such as the LCD screen is damaged or the glass is scratched) needs to be repaired or replaced, it must be disassembled with special tools, which is inefficient and further increases maintenance costs. In addition, adhesive filling requires strict control of the amount of adhesive applied, the uniformity of the adhesive, and the curing time. The process is complex and has high requirements for environmental temperature and humidity, making it difficult to adapt to the high-efficiency assembly requirements of large-scale mass production scenarios.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a full LCD instrument installation structure that does not require glue filling and bonding, is simple and efficient to assemble, and has low maintenance costs. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a simple and efficient full LCD instrument installation structure to solve the problems of high cost and inconvenient replacement of full LCD instrument display screen and protective glass in the prior art, while improving assembly efficiency.

[0005] A simple and efficient full LCD instrument mounting structure includes: a front frame and a bottom shell; an acrylic glass is clamped between the front frame and the bottom shell; an LCD screen is installed inside the bottom shell; the acrylic glass serves as protective glass for the LCD screen; dustproof cotton is filled between the LCD screen and the acrylic glass, the dustproof cotton having a frame-shaped structure and its inner ring contour matching the display area contour of the LCD screen; the front frame, acrylic glass, and bottom shell are connected and fixed by screw assemblies, and a snap-fit ​​assembly and a positioning assembly are also provided between the front frame, acrylic glass, and bottom shell for auxiliary installation.

[0006] As a preferred embodiment of this utility model, the buckle assembly includes a slot plate and a hook. The slot plate is fixedly installed on both sides of the front frame. The bottom shell has a limiting groove on both sides corresponding to the slot plate. The slot plate is inserted and assembled in the limiting groove along the horizontal direction. The hook is fixedly installed in the limiting groove and is engaged and fixed with the groove on the slot plate.

[0007] As a preferred embodiment of this utility model, the buckle assembly is provided in two sets and is symmetrically installed on the left and right sides of the front frame and the bottom shell.

[0008] As a preferred embodiment of the present invention, the positioning component includes a positioning post and a positioning groove. The positioning post is fixedly installed on the bottom shell, and the positioning groove is located at a corresponding position on the front frame. The positioning post is inserted and assembled in the positioning groove.

[0009] As a preferred embodiment of this utility model, the positioning components are configured in three groups: one group is located at the middle of the upper end face of the front frame and the bottom shell, and two groups are symmetrically located on the lower end face of the front frame and the bottom shell. The three groups of positioning components are arranged in a triangular configuration.

[0010] In a preferred embodiment of this utility model, the thickness of the dustproof cotton is 1mm.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] This invention achieves the fixation of the acrylic glass and LCD screen through a mechanical connection between the front frame and the bottom shell, eliminating the need to purchase special glue and gluing equipment, thus reducing raw material and equipment costs. Furthermore, the assembly process only requires three steps: positioning, pre-fixing with clips, and tightening with screws. This simplifies the process, significantly improves assembly efficiency, and is suitable for large-scale mass production. When the LCD screen or acrylic glass is damaged, the front frame and bottom shell can be disassembled simply by removing the screw assembly and separating the clip assembly, allowing direct replacement of the damaged parts without dismantling the solidified adhesive structure, reducing maintenance difficulty and costs.

[0020] like Figures 1 to 4 As shown, a specific embodiment of the simple and efficient full LCD instrument mounting structure of this utility model includes:

[0021] The front frame 1 and the bottom shell 3 are sandwiched between the front frame 1 and the bottom shell 3. An plexiglass 2 is installed inside the bottom shell 3. The plexiglass 2 serves as protective glass to protect the LCD screen 7. The front frame 1, the plexiglass 2, and the bottom shell 3 are connected and fixed by a screw assembly 5.

[0022] Dustproof cotton 8 is filled between the LCD screen 7 and the plexiglass 2. The dustproof cotton 8 has a frame structure, a thickness of 1mm, and its inner circle contour is adapted to the display area contour of the LCD screen 7.

[0023] The buckle assembly 6 includes a slot plate 61 and a hook 62. The slot plate 61 is fixedly installed on both sides of the front frame 1. The bottom shell 3 has a limiting groove on both sides corresponding to the slot plate 61. The slot plate 61 is inserted into the limiting groove in the horizontal direction. The hook 62 is fixedly installed in the limiting groove and is engaged with the groove on the slot plate 61. The buckle assembly 6 is set into two sets and is symmetrically installed on the left and right sides of the front frame 1 and the bottom shell 3.
