Description

Technical Field

[0001] The utility model relates to the field of trucks, and particularly to a hinged door of a low-entry truck. Background Art

[0002] Trucks, as important tools for road transportation, play an indispensable role in the modern logistics system with their strong load-bearing capacity and flexible adaptability. They usually have a solid body structure, paired with a powerful engine, and can easily handle various complex road conditions and the needs of long-distance transportation. The exterior design of trucks is often simple and practical. The cab is integrated into the front part of the truck, providing a comfortable driving environment and good visibility for the driver to ensure driving safety.

[0003] In terms of the carriage design, trucks can be divided into various types according to the different goods to be transported, such as van trucks, flatbed trucks, refrigerated trucks, tank trucks, etc. With the progress of technology, modern trucks are becoming more and more intelligent. Many vehicles are equipped with advanced driving assistance systems, such as automatic emergency braking, lane keeping assistance, blind spot monitoring, etc. These technologies not only improve driving safety but also reduce the labor intensity of drivers.

[0004] For example, the utility model with the application number CN202223589568.0 and the name of a lightweight door for a heavy-duty truck includes an outer door panel and an inner door panel fixedly connected to each other. The outer door panel is an SMC outer door panel, and the inner door panel is an SMC inner door panel; the outer door panel and the inner door panel are fixedly connected by structural adhesive. Excessive pursuit of lightweight leads to low installation strength of various components installed on the door, which is prone to damage and has a high usage cost. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a hinged door for a low-entry truck, aiming to improve the problem that excessive pursuit of lightweight of the existing truck doors leads to low installation strength of various components installed on the doors, which are prone to damage and have a high usage cost.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hinged door for a low-entry truck includes a main door panel. An inner ring pipe frame assembly is fixed on the inner side surface of the main door panel. An installation hinge is fixed on the side surface of the inner ring pipe frame assembly. A first reinforcing plate is arranged inside the inner ring pipe frame assembly. The first reinforcing plate corresponds to the installation hinge one by one, and the installation hinge passes through the inner ring pipe frame assembly and is fixedly connected to the first reinforcing plate.

[0008] Further, a sight channel is opened in the upper part of the main door panel, and a visible sealing plate is adhesively fixed on the upper outer side of the main door panel;

[0009] A lifting window assembly is fixed to the lower inner part of the door panel main body. The visual sealing plate is provided with a lifting window opening, and the lifting window opening is located above the lifting window assembly.

[0010] Furthermore, a rearview mirror assembly and a blind spot mirror assembly are fixed to the outer side of the door panel main body.

[0011] A lower mounting seat and a mounting plate are fixed to the outer side of the door panel main body. The upper mounting part and the lower mounting part of the rearview mirror assembly are respectively fixedly connected to the mounting plate and the lower mounting seat. An upper mounting seat is fixed to the top of the outer side of the door panel main body, and the blind spot mirror is fixed to the upper mounting seat.

[0012] The visual sealing plate is provided with a first notch and a second notch, and the first notch and the second notch respectively correspond to the positions of the mounting plate and the upper mounting seat.

[0013] Furthermore, an interior trim panel is fixed to the inner side surface of the inner ring pipe frame assembly. The interior trim panel covers the lower part of the inner ring pipe frame assembly. The inner ring pipe frame assembly, the interior trim panel and the door panel main body enclose an installation space, and a door lock function assembly is arranged in the installation space.

[0014] Furthermore, a warning lamp is fixed to the side surface of the interior trim panel away from the installation hinge.

[0015] Furthermore, the inner ring pipe frame assembly includes an upper ring pipe and a lower ring pipe. The upper ring pipe surrounds the top edge of the door panel main body, and the lower ring pipe surrounds the bottom edge of the door panel main body. The bottom of the upper ring pipe is in abutting contact with the top of the lower ring pipe.

[0016] The top of the lower ring pipe is provided with a pressing pipe extending outward, and the pressing pipe presses on the bottom of the upper ring pipe.

[0017] Furthermore, a plurality of installation through holes are formed in the top side surface of the lower ring pipe. The interior trim panel covers the lower ring pipe, and an inner door handle is fixed to the interior trim panel. The inner door handle passes through the installation through holes and is connected to the door lock function assembly.

[0018] Furthermore, a bending part is arranged in the middle of the door panel main body. The upper part of the door panel main body is located inside the lower part of the door panel main body, and the outer side surface of the visual sealing plate is flush with the lower part of the door panel main body.

[0019] Furthermore, an outer door handle is fixed to the lower part of the door panel main body. The outer door handle passes through the door panel main body and is connected to the door lock function assembly.
