Description

Technical Field

[0001] This utility model relates to the field of automotive interior structure technology, and in particular to an improved structure of a split-type LCD instrument panel mounting base. Background Technology

[0002] With the development of intelligent vehicles and electric vehicles, in-vehicle LCD instrument panels have become an important component of the central control system. LCD instrument panels are generally installed within the instrument panel cover in front of the driver's seat, achieving both aesthetic appeal and functional integration through an embedded design. However, existing LCD instrument panel base structures are generally of a one-piece design, which has the following drawbacks:

[0003] Complex assembly: In situations where space is limited within the instrument panel, an integrated structure makes it difficult to install components such as displays and circuit boards step by step; Inconvenient maintenance: When the instrument malfunctions or needs to replace parts, it must be completely disassembled, which is time-consuming and labor-intensive; Limited wiring: Integrated structures usually have compact internal space, limiting the path for wiring; Impaired thermal management: Some bases lack heat dissipation channels, causing the instrument panel to operate unstablely under high-temperature conditions. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a split-type vehicle LCD instrument panel base, which features a precise shell assembly, convenient disassembly and assembly, and easy maintenance; the overall modules are clearly defined and can be adapted to different LCD panels and circuit platforms.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: the upper housing 1 and the lower housing 2 are designed as separate units. During assembly, components such as the circuit board and LCD module can be installed inside the lower housing 2 first, and then the upper housing 1 can be snapped in place from above, ultimately achieving a quick connection through snap-fit ​​mechanisms. This structure facilitates modular installation and step-by-step operation, reduces assembly complexity, improves production efficiency, and also facilitates subsequent disassembly and maintenance.

[0006] The upper housing 1 has a hollowed-out structure in the middle. Two hook-shaped buckles 11 are provided on the back of the upper housing 1. A reinforcing rib 12 extends from the lower part of each buckle 11, and the reinforcing rib 12 has a double-layer structure. The hollowed-out middle section of the upper housing 1 provides a display window for the LCD screen. The hooks and buckles 11 facilitate mounting on the dashboard support structure or slots, while the reinforcing rib 12 provides additional structural strength, preventing the buckles from breaking or deforming under stress. This double-structure design of hooks and reinforcing ribs improves the connection stability and durability of the housing, while the hollowed-out area provides space for functional components, ensuring a clear and unobstructed display.

[0007] A fixing buckle 13 is provided at the upper front edge of the upper housing 1, and the fixing buckles 13 are distributed on both sides of the front of the upper housing 1. The fixing buckle 13 cooperates with the internal structure of the lower housing or the dashboard to help fix the position of the upper housing and prevent the upper housing from loosening due to vibration. This enhances the overall assembly stability, keeps the structure stable even under the vibration of automobile driving, and avoids abnormal noise or displacement.

[0008] The upper housing 1 and the lower housing 2 are connected by bolts or pins. In addition to the snap-fit ​​connection, the upper and lower housings are further reinforced by bolts or pins, thus achieving a double fixing mechanism and improving the connection strength. This enhances resistance to disassembly and reliability, making it suitable for complex working conditions and high-intensity usage environments, and also facilitating disassembly, maintenance, or component replacement.

[0009] The upper housing 1 has a honeycomb-shaped perforation 14 on one side of its front portion, which facilitates the sound output of the built-in speaker. The honeycomb perforation 14 corresponds to the area of ​​the built-in buzzer or speaker, serving to conduct sound waves and ensure that the sound is clearly transmitted to the outside of the cockpit. It can improve acoustic output efficiency, while the honeycomb structure provides ventilation and protection, preventing dust and foreign objects from entering, and maintaining the overall strength of the outer shell.

[0010] The lower housing 2 is internally equipped with a boss 21 for supporting the LCD screen, a positioning mounting plate 22 for mounting the circuit board, and guide posts 23 for mounting and positioning. The LCD screen boss 21 supports the LCD module, ensuring that the display device is installed horizontally; the mounting plate 22 provides a fixing base for the circuit board, and the guide posts 23 assist in alignment and assembly. This ensures reliable module fixation, precise structural assembly, effectively improves the shock resistance of internal components and the neatness of wiring, and guarantees overall stable operation.

[0011] The lower housing 2 has several snap-fit ​​holes 24 around its upper surface. The lower periphery of the upper housing 1 has an extension plate 15 corresponding to the snap-fit ​​holes 24. The extension plate 15 snaps into the snap-fit ​​holes 24. At the connection point between the extension plate 15 and the upper housing 1, it extends upward to form a reinforcing rib 12, which is integrally formed with the extension plate 15. The extension plate 15, as a connecting structure, is inserted into the snap-fit ​​holes 24 for fixation and simultaneously connects with the reinforcing rib 12 to form an integral rigid structure, further enhancing the overall strength of the housing. This improves the stability and deformation resistance of the upper and lower housings, enhances the impact resistance and durability of the overall structure, and avoids stress concentration leading to snap-fit ​​fatigue fracture.

[0012] A screw mounting plate 25 is provided on the front side of the lower housing 2, and screw holes 26 are provided on the screw mounting plate 25. The screw mounting plate 25 is used to fix the entire housing assembly to the vehicle dashboard frame, and the screw holes 26 facilitate quick installation and tightening. This ensures that the structure is reliably installed in the vehicle frame, has good vibration resistance and positioning stability, and meets the requirements of automotive component structural parts for reliable installation.

[0013] The working principle of this utility model:

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: it adopts a split structure and is flexible in assembly, which greatly improves the installation efficiency and maintenance convenience of the LCD instrument; through multiple connection methods such as reinforcing ribs, buckles, and screws, the overall strength and shock resistance of the shell are enhanced; the honeycomb sound outlet design optimizes the sound output path, while also having heat dissipation and protection functions. The overall technical solution has significant improvements in structural stability, functional integration and assembly convenience. Attached Figure Description
