Description

Technical Field

[0001] This utility model relates to a universal installation device for electronic rearview mirror displays in commercial vehicles, belonging to the field of commercial vehicle parts installation technology. Background Technology

[0002] In the commercial vehicle sector, the installation method of electronic rearview mirror displays has a crucial impact on the overall performance, ease of use, and safety of the vehicle. With the continuous development of the commercial vehicle industry, the requirements for electronic rearview mirror display installation are also increasing. However, current installation devices are often complex in structure and lack universality. Different vehicle models often require different installation components, which not only increases the variety of parts and management difficulty in the production process but also requires manufacturers to invest more manpower and resources in research and development. Consequently, when installing electronic rearview mirror displays, it is often necessary to develop specialized installation devices for specific vehicle models, resulting in a complex and costly installation process, and making it difficult to achieve universal installation across different vehicle models. Moreover, in some existing installation technologies, the wiring harness is not properly arranged and protected, often being exposed. This not only seriously affects the aesthetics of the vehicle interior and reduces the overall quality of the vehicle but also poses significant safety hazards. Exposed wiring harnesses may be subjected to external forces such as friction, compression, and collisions during vehicle operation, leading to damage to the outer sheath, short circuits, or open circuits in the internal wiring, thereby affecting the normal operation of the electronic rearview mirror display and potentially causing vehicle electrical faults, threatening driving safety. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a universal installation device for electronic rearview mirror displays in commercial vehicles. This utility model enables universal installation of electronic rearview mirror displays across different vehicle models, reducing research and development and production costs. Furthermore, this utility model can properly arrange and protect the wiring harness, reducing safety hazards caused by damage to the wiring harness.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a universal mounting device for an electronic rearview mirror display screen in commercial vehicles, comprising at least an A-pillar trim panel, a display screen, an armrest, and a plastic cover. The universal mounting device includes a universal mounting structure, which consists of a main pipe and a secondary pipe. The main pipe and the secondary pipe are hollow round tubes. The main pipe is used to pass through the mounting hole in the A-pillar trim panel and connect to the armrest, while the secondary pipe is used to mount the display screen. A wiring harness hole is opened at the bottom of the main pipe. The wiring harness passes through the wiring harness hole in the main pipe from inside the A-pillar trim panel of the commercial vehicle, and then through the secondary pipe to reach the display screen end. The display screen is mounted on the armrest through the universal mounting structure, and the plastic cover is mounted on the top of the universal mounting structure.

[0005] Furthermore, the main mounting hole of the display screen is located at the bottom of the main pipe, sharing the same mounting hole as the handrail. The universal mounting structure is fixedly connected to the handrail with bolts.

[0006] Furthermore, the A-pillar trim panel is provided with a round hole that matches the main pipe. The diameter of the round hole is 42mm, and the center of the round hole is concentric with the mounting hole on the armrest. The precise positioning of the installation position is achieved by using the position of the mounting hole on the armrest.

[0007] Furthermore, the upper end of the armrest is provided with a mounting surface and screw holes. Five degrees of freedom of the display screen are controlled through a mounting hole and a mounting surface, and the last rotational degree of freedom of the display screen is controlled by installing screws on the armrest.

[0008] Furthermore, the diameter of the main tube is 40mm, and the diameter of the secondary tube is 28mm.

[0009] Moreover, the universal mounting structure can be adapted to all commercial vehicles with armrest mounting points on the A-pillar. For different vehicle models, it can be adapted by adjusting the welding angle of the main pipe and the auxiliary pipe, as well as the installation height of the display screen and the auxiliary pipe.

[0010] Furthermore, the plastic cap is connected to the top of the main pipe by a snap or thread, enabling quick disassembly and decoration.

[0011] As can be seen from the above technical solution, the low-temperature heated display screen structure for electronic rearview mirrors provided by this utility model has the following advantages compared with the prior art:

[0012] (1) In the technical solution adopted by this utility model, the main mounting hole of the display screen and the armrest share the same mounting hole. The armrest is fixedly connected by bolts, which makes the installation method simple. Moreover, the round hole on the A-pillar trim panel is concentric with the mounting hole on the armrest. The position of the mounting hole on the armrest can be used to achieve precise positioning of the installation position, which reduces the debugging time during the installation process and improves the installation efficiency and accuracy.

[0013] (2) The general installation structure in the technical solution adopted by this utility model consists of a main pipe and a secondary pipe, which can be adapted to all commercial vehicles with handrail mounting points on the A-pillar. For different models, the welding angle of the main pipe and the secondary pipe and the installation height of the display screen and the secondary pipe are adjusted to adapt to each model. There is no need to design a separate installation device for each model, which reduces the research and development and production costs and improves the applicability of the product.

[0014] (3) In the technical solution adopted by this utility model, the bottom end of the main pipe has a wire harness hole. The wire harness passes through the wire harness hole of the main pipe from inside the A-pillar trim panel of the commercial vehicle, and then passes through the secondary pipe to the display screen end. This layout hides the wire harness inside the installation device, avoiding problems such as damage and tangling that may be caused by exposed wire harness, improving the safety and stability of the wire harness, and also making the interior of the vehicle look cleaner and more beautiful.

[0015] (4) In the technical solution adopted by this utility model, the plastic plug is installed on the top of the universal installation structure and is connected to the top of the main pipe by a buckle or thread. It not only plays a decorative role and improves the overall aesthetics of the vehicle interior, but also facilitates quick disassembly and makes it easy to inspect, repair or replace parts inside the installation device.

[0016] (5) In the technical solution adopted by this utility model, the main tube and the auxiliary tube are hollow round tube structures. While ensuring the structural strength, the weight of the device is reduced. The hollow structure can be used to arrange the wiring harness, effectively utilizing the space and avoiding the additional space occupied by the wiring harness arrangement, making the internal structure of the vehicle more compact and reasonable.
