Description

Technical Field

[0001] This utility model relates to the field of automotive electronic device support structures, specifically to a vehicle-mounted LCD instrument panel base bracket structure for mounting LCD instrument panels. Background Technology

[0002] With the continuous improvement of automotive intelligence, LCD instrument panels, as core components for information integration and human-machine interaction, have widely replaced traditional mechanical instruments. However, in actual vehicle operation, especially under complex road conditions, long-term driving, or high-frequency vibration environments, traditional LCD instrument panel mounting brackets generally suffer from the following technical defects:

[0003] The structural fixing method is simple and the seismic performance is insufficient: the existing instrument panel brackets mostly use clips or a few screws for fixing. Long-term vibration can cause the connection parts to loosen or even fall off, posing a safety hazard.

[0004] Poor assembly tolerance control can easily lead to abnormal noises: Due to the low matching accuracy between the bracket and the LCD module and the vehicle body mounting position, the parts are prone to friction and collision under the high-frequency resonance during vehicle operation, forming "resonance noise" or "plastic noise", which seriously affects the driving experience.

[0005] The overall structure lacks reinforcement design: Most existing brackets are simple injection molded parts, lacking internal reinforcing ribs and limiting ribs, which cannot effectively disperse vibration stress, leading to bracket deformation or cracks, further affecting the stability and service life of the LCD instrument.

[0006] The lack of proper cabling planning makes maintenance inconvenient: Traditional brackets do not have an independent cabling structure, and the wires are often squeezed into the gaps or corners of the bracket, which not only makes installation difficult, but also easily causes problems such as wire wear and unstable signals. Utility Model Content

[0007] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a vehicle LCD instrument panel base bracket. By optimizing the bracket structure and installation method, it effectively improves the stability of the LCD instrument panel under long-term vibration conditions in vehicles, and significantly reduces loosening and abnormal noise problems.

[0008] 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, and the upper shell 1 and the lower shell 2 are an integral structure. 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, and 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. A support shell 21 is provided on the periphery of the lower shell 2, and the support shell 21 is perpendicular to the bottom plate of the lower shell 2.

[0009] Several reinforcing ribs 111 are provided on the outer side of the outer shell 11, and the bottom of the reinforcing ribs 111 is fixedly connected to the lower shell 2.

[0010] The outermost two reinforcing ribs 111 on the outer shell 11 are respectively provided with snap-fit ​​frames 112, and the snap-fit ​​frames 112 protrude from the outer shell 11.

[0011] The outer side of the bracket housing 21 is provided with two protruding connecting seats 211. The connecting seats 211 protrude from the outer side of the bracket housing 21 and are integral with the bracket housing 21. The connecting seats 211 are provided with screw holes 212.

[0012] Several snap-fit ​​buckles 213 are provided around the bottom periphery of the bracket housing 21. The snap-fit ​​buckles 213 are used to connect to the vehicle body.

[0013] Several square positioning posts 22 are vertically arranged inside the lower housing 2, and the square positioning posts 22 are integrated with the lower housing 2.

[0014] The working principle of this utility model is as follows: In practical use, the integrated upper and lower shell structure achieves stable enclosure and positioning of the LCD instrument panel. The upper shell includes an outer shell and an inner shell. The inner shell is an integral double-arc cylindrical structure, and the outer shell is a sheet-like arc structure. After fitting together, they form a double-barrel-shaped reinforcing structure, which not only provides an aesthetic concealment effect but also strengthens the structure of the inner shell. Multiple reinforcing ribs are provided on the outer side of the outer shell. The bottom of the ribs is fixed to the lower shell to enhance the overall vibration resistance of the bracket and reduce the risk of deformation or loosening caused by vehicle vibration. The two outermost ribs are equipped with snap-fit ​​frames that protrude from the surface of the outer shell, used to achieve stable insertion and engagement with the LCD instrument panel or front decorative panel, preventing module wobbling. A bracket shell is provided around the lower shell, perpendicular to the base plate. Two protruding connecting seats are provided on its outer side. The connecting seats are an integral structure with screw holes for rigid fixing of screws to vehicle body structural components.

[0015] In addition, the bottom edge of the bracket housing has multiple snap-fit ​​buckles, which are used to quickly lock into the docking structure inside the vehicle's dashboard, improving assembly efficiency. To ensure the vertical positioning accuracy of the instrument installation, multiple square positioning posts are set inside the lower housing. These positioning posts match the back of the LCD module or the connecting bracket, serving to limit and support the position of the LCD screen and prevent it from shifting or dislodging due to vibration during vehicle operation.

[0016] The beneficial effects of adopting the above technical solution are as follows: it improves the stability of the LCD instrument panel under long-term vehicle vibration conditions, avoiding instrument displacement or failure due to loose connections; it reduces the assembly gap and frictional contact between parts, effectively eliminating structural noise caused by resonance; it strengthens the housing structure, extending the service life of the bracket and LCD module; it optimizes the wiring harness layout channel, improving assembly efficiency and ease of later maintenance; and the heat dissipation grille design helps dissipate heat from the instrument module, maintaining a stable system operating temperature.

Detailed Implementation

[0022] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is as follows: 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, and the upper shell 1 and the lower shell 2 are an integral structure. 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, and 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. A support shell 21 is provided on the periphery of the lower shell 2, and the support shell 21 is perpendicular to the bottom plate of the lower shell 2. Several reinforcing ribs 111 are provided on the outer side of the outer shell 11, and the bottom of the reinforcing ribs 111 is fixedly connected to the lower shell 2. The outermost two ribs of the reinforcing ribs 111 on the outer shell 11 are respectively provided with snap-fit ​​frames 112, and the snap-fit ​​frames 112 protrude from the outer shell 11. The outer side of the bracket housing 21 has two protruding connecting seats 211. The connecting seats 211 protrude from the outer side of the bracket housing 21 and are integrally formed with the bracket housing 21. The connecting seats 211 are provided with screw holes 212. Several snap-fit ​​buckles 213 are provided around the bottom periphery of the bracket housing 21. The snap-fit ​​buckles 213 are used to connect and snap onto the vehicle body. Several square positioning posts 22 are vertically arranged inside the lower housing 2. The square positioning posts 22 are integrally designed with the lower housing 2.

[0023] In practical use, the integrated upper and lower housing structure provides a stable enclosure and positioning for the LCD instrument panel. The upper housing consists of an outer shell and an inner shell. The inner shell is an integral double-arc cylindrical structure, while the outer shell is a sheet-like arc-shaped structure. After fitting together, they form a double-barrel-like reinforcing structure, providing not only aesthetic concealment but also structural reinforcement for the inner shell. Multiple reinforcing ribs are located on the outer side of the outer shell, with their bottoms fixed to the lower housing. This enhances the overall vibration resistance of the bracket, reducing the risk of deformation or loosening due to vehicle vibrations. The two outermost reinforcing ribs have snap-fit ​​frames protruding from the outer shell surface, ensuring a stable connection with the LCD instrument panel or front decorative panel and preventing module wobbling. The lower housing is surrounded by a bracket housing, perpendicular to the base plate. Two protruding connecting seats are located on its outer side. These seats are an integral structure with screw holes for rigid fixing of screws to vehicle structural components.

[0024] In addition, the bottom edge of the bracket housing has multiple snap-fit ​​buckles, which are used to quickly lock into the docking structure inside the vehicle's dashboard, improving assembly efficiency. To ensure the vertical positioning accuracy of the instrument installation, multiple square positioning posts are set inside the lower housing. These positioning posts match the back of the LCD module or the connecting bracket, serving to limit and support the position of the LCD screen and prevent it from shifting or dislodging due to vibration during vehicle operation.

[0025] This specific implementation improves the stability of the LCD instrument panel under long-term vehicle vibration conditions, preventing instrument displacement or failure due to loose connections; reduces assembly gaps and frictional contact between components, effectively eliminating structural noise caused by resonance; strengthens the housing structure, extending the service life of the bracket and LCD module; optimizes the wiring harness layout channel, improving assembly efficiency and ease of later maintenance; and the heat dissipation grille design helps dissipate heat from the instrument module, maintaining a stable system operating temperature.

[0026] The design features a split structure, allowing the base and upper shell to be disassembled independently. This facilitates the inspection, replacement, and repair of components such as the LCD monitor, circuit board, and wiring harness, significantly reducing after-sales maintenance costs.

[0027] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
