Description

Technical Field

[0001] This utility model relates to the field of side door beam technology, and in particular to a side door beam for a transport vehicle. Background Technology

[0002] In the design and manufacture of transport vehicles, doors, as a crucial component, must not only fulfill basic opening and closing functions but also possess sufficient strength, stability, and durability to withstand the challenges of complex road conditions and high-intensity usage environments. Traditional door side beam structures typically employ simple frame designs. While these may meet basic requirements in ordinary usage scenarios, in heavy vehicles such as transport trucks, where they are subjected to significant impacts, vibrations, and loads over extended periods, traditional structures are prone to deformation, cracking, or loosening of connections. This can affect the normal use of the door and the overall safety of the vehicle.

[0003] Therefore, it is essential to invent a side door beam for a transport vehicle. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a side door beam for a transport vehicle, solving the issues that existing side door beams for transport vehicles still cannot withstand impact forces for extended periods, are prone to significant deformation, and have poor protective capabilities. A side door beam for a transport vehicle includes a lower side beam, a lower bottom beam, a middle reinforcing frame, a door reinforcing plate, an upper side beam, and connecting bolt holes. The lower bottom beam is fixedly installed at the bottom of two sets of lower side beams, and the middle reinforcing frame is fixedly installed at the top of the two sets of lower side beams. The door reinforcing plate is fixedly installed between the lower side beams, the lower bottom beam, and the middle reinforcing frame. Connecting bolt holes are provided on the upper side beam and the middle reinforcing frame, and bolts are used to connect the middle reinforcing frame and the upper side beam together.

[0005] The intermediate reinforcing frame includes a mounting plate, a relief plate, a reinforcing rib, a lower connecting plate, and a lower splicing groove. The mounting plate is fixedly installed on the top of the two sets of lower side beams, and the relief plate is fixedly installed above the mounting plate. The reinforcing rib is fixedly installed between the mounting plate and the relief plate, and the lower connecting plate is fixedly installed above the relief plate. The lower splicing groove is formed on the lower connecting plate.

[0006] The upper edge beam includes a door window beam, an upper connecting plate, an upper splicing groove, a reinforcing frame, a protective layer, and a door window. The upper connecting plate is fixedly installed at the lower end of the door window beam, and the upper splicing groove is formed on the upper connecting plate. The upper connecting plate and the lower connecting plate are spliced ​​together through the upper splicing groove and the lower splicing groove. The reinforcing frame is fixedly installed on the surface of the door window beam, and the door window is installed on the surface of the protective layer.

[0007] The middle reinforcing frame is made of a single steel metal structure, and the relief plate bends inward at the top of the mounting plate. The lower connecting plate continues to extend upward on the relief plate. The reinforcing ribs are made of several parallel triangular steel metal structures, and the lower splicing groove is a groove that is recessed inward on the lower connecting plate.

[0008] The shape of the upper edge beam is consistent with the window above the vehicle door, and the door window beam adopts a window-shaped steel metal structure. The upper splicing groove is a groove recessed inward on the upper connecting plate. After the upper connecting plate and the lower connecting plate are spliced ​​together by the upper splicing groove and the lower splicing groove, the overall thickness is consistent with the upper connecting plate and the lower connecting plate. The reinforcing frame is a steel metal frame with the same shape as the door window beam, and the reinforcing frame thickens the door window beam.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The intermediate reinforcing frame of this utility model, through its internal components, tightly connects the lower side beam and the upper side beam, forming a stable frame structure that effectively distributes and withstands the impact and vibration experienced by the door during transportation. The reinforcing ribs adopt a triangular steel metal structure, significantly improving bending and compressive strength and preventing door deformation or damage. Simultaneously, the design of the clearance plate and lower connecting plate provides installation space for other components and ensures coordination with the overall door structure. The intermediate reinforcing frame is fixed to the upper side beam through connecting bolt holes, further enhancing the structural stability and durability, making it suitable for high-intensity transportation environments.

[0011] 2. The upper side beam of this utility model provides stable support for the door window via the door window beam. It is joined with the lower side plate and lower splicing groove of the middle reinforcing frame via the upper connecting plate and upper splicing groove, ensuring a tight connection between the upper and lower parts and the stability of the overall structure. The reinforcing frame further thickens the door window beam, enhancing its resistance to pressure and deformation. The overall shape of the upper side beam is consistent with the door window, optimizing functionality and ensuring coordination with other components, significantly improving the strength, stability, and durability of the door, making it suitable for high-intensity transportation environments.
