Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a mounting structure for a vehicle instrument panel with a liquid crystal display, especially a vehicle instrument panel mounting structure with a split mounting structure. Background Technology

[0002] With the continuous development of automotive electronics technology, LCD instrument panels have gradually replaced traditional mechanical instruments, becoming an important component of modern intelligent vehicles. LCD instrument panels offer advantages such as customizable interfaces, rich information display, and strong interactivity, making them particularly suitable for new energy vehicles and mid-to-high-end models. To achieve the integration of functional components such as display modules, control circuits, and power modules, the instrument panel housing, as the supporting platform, must possess excellent structural adaptability, stability, and ease of assembly.

[0003] Currently, most mainstream LCD instrument panel housings on the market adopt a one-piece injection molding structure, meaning the housing cover, base, and internal mounting support are molded in one piece. While this structure is more efficient in mold development and mass production, it has the following problems:

[0004] 1. Inconvenient assembly: The integrated structure limits the operating space during the installation of LCD modules and circuit boards, and the wiring is complicated, which can easily cause damage to the wire harness or improper installation.

[0005] 2. Difficulty in maintenance: When a component inside the dashboard is damaged, it is often necessary to disassemble the entire dashboard assembly, which increases the difficulty and time cost of repair;

[0006] 3. Lack of modular support: Traditional structures are difficult to quickly adapt to LCD modules of different models, sizes or resolutions, which limits the product's scalability and customization capabilities;

[0007] 4. Significant stress integration issues: When the one-piece molded structure is subjected to vehicle vibration or thermal expansion and contraction, local cracking or screw loosening is likely to occur. Utility Model Content

[0008] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a vehicle LCD instrument panel holder that adopts a split installation method. It achieves modular structure, convenient installation and space optimization by splicing and fixing the upper and lower structural components. Multiple sets of buckles and positioning structures ensure a firm installation while facilitating disassembly.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: it includes an upper shell 1 and a lower shell 2, the upper shell 1 is fixedly disposed on the upper part of the lower shell 2; the upper shell 1 includes an outer shell 11 and an inner shell 12, the inner shell 12 is an integral double-arc cylindrical shape, the outer shell 11 is a sheet-like arc shape, the outer shell 11 is attached to the upper part of the inner shell 12 and forms a double-barrel-shaped upper shell 1 with the inner shell 12.

[0010] The outer side of the outer shell 11 is provided with several reinforcing ribs 111, the bottom of which is fixedly connected to the lower shell 2. The outer side of the top of the outer shell 11 is provided with two upper snap-fit ​​connectors 112. The upper snap-fit ​​connectors 112 are used to connect the interior trim panels of the vehicle body.

[0011] The lower housing 2 has several positioning posts 21 on its four bottom sides, and several insertion plates 22 on its lower rear side. The insertion plates 22 have square snap-fit ​​holes 221. The insertion plates 22 are used to be inserted into the interior trim panels of the vehicle body.

[0012] The lower housing 2 has protruding U-shaped slot buckles 23 on both sides. The U-shaped slot buckles 23 are inserted into the interior trim panel of the vehicle body and then fastened. The U-shaped slot buckles 23 can ensure a tight connection between the instrument panel and the interior trim panel.

[0013] A screw hole connector 24 is provided at one end of the front side of the lower housing 2. The screw hole connector 24 has a box-shaped structure and a through hole 241 is provided inside the screw hole connector 24. The through hole 241 is used to insert fastening screws or buckles.

[0014] The lower housing 2 is provided with T-shaped buckles 242 on its outer side. The T-shaped buckles 242 are integrally designed with the lower housing 2, and a buckle groove 243 is provided in the middle of the T-shaped buckle 242. The T-shaped buckles 242 with a buckle groove 243 in the middle can better lock and make the T-shaped buckles 242 act as expansion buckles.

[0015] The working principle of this utility model is as follows: It adopts a split structure. The lower shell 2 is an integral, arc-shaped, closed shell structure. The outer periphery of the lower shell 2 is equipped with several snap-fits, positioning posts, and limiting ribs. During assembly, it is firmly connected to the upper shell through snap-fit ​​and screw engagement, forming a sealed support cavity. The cavity of the lower shell 2 is used to support core components such as the LCD display module, circuit board, and power module, ensuring their stability and preventing displacement during vehicle operation. To cope with vibrations generated during vehicle operation, the base has several rib structures and locally thickened areas, improving overall strength without significantly increasing weight. Simultaneously, the internal space is rationally divided to accommodate buffer pads or rubber shock-absorbing pads, thereby improving component lifespan.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] Improved assembly efficiency: The base and upper shell adopt a snap-fit ​​and positioning guide rail structure, which can realize quick and accurate assembly and disassembly, significantly improving production assembly efficiency and subsequent maintenance convenience.

[0018] Enhanced structural stability: The base adopts a reinforced design and is equipped with limiting ribs and positioning columns, which can effectively improve the overall rigidity of the shell and reduce the risk of structural resonance and component loosening during vehicle operation.

[0019] High module compatibility: The base has standardized mounting slots inside, which can be used to fit different sizes and models of LCD modules, circuit boards and other electronic components, making it easy for OEMs to flexibly select and replace them according to the needs of the vehicle model.

[0020] Reasonable wiring layout: The base is equipped with multiple sets of wiring through holes and wire clamping structures, which makes the power lines, signal lines, etc. clear, reduces the risk of cross-entanglement and interference, and improves the stability and EMC performance of the vehicle's electronic system.

[0021] Manufacturing process friendly: The base structure is suitable for various manufacturing methods such as injection molding and CNC machining, which facilitates mass production, reduces costs, and ensures product consistency.

[0022] Convenient maintenance: The split structure design allows the base and upper shell to be disassembled independently, facilitating the inspection, replacement, and repair of components such as the LCD monitor, circuit board, and wiring harness, significantly reducing after-sales maintenance costs.
