Description

Technical Field

[0001] The utility model relates to the technical field of automobile frames, in particular to a metal frame. Background Art

[0002] The automobile frame, also known as the automobile chassis frame or automobile body frame, is the main load-bearing structure of the automobile. It is usually made of steel, aluminum alloy or other high-strength materials. The frame supports various components of the automobile and is the basic structure connecting multiple important components such as the body, engine, suspension system, and wheels.

[0003] Existing automobile frames generally connect two longitudinal beams through a crossbeam, which is connected by welding, riveting or bolts. Bolts are mostly used to ensure structural stability and strength. However, the connection between the crossbeam and the longitudinal beam is easily loosened, unscrewed or even broken by bolts when the car is running, affecting the safety of use. At the same time, the support strength between the longitudinal beams is low due to the crossbeam alone. Therefore, we designed a metal frame. Utility Model Content

[0006] Through the above technical solution, the present application installs the crossbeam on the mounting frame on the left longitudinal beam and the right longitudinal beam through the first fastening bolt. At this time, the position of the crossbeam between the limit plates is limited, thereby ensuring the supporting effect of the crossbeam and the stability of the connection between the crossbeam and the longitudinal beam. Then, the support bar is placed into the first fixing frame and the second fixing frame, and the support bar is fixed by the second fastening bolt and the third fastening bolt. At this time, the two ends of the support bar respectively support the crossbeam and the limit plate, thereby supporting the crossbeam and the longitudinal beam and strengthening their structural strength. During the maintenance, disassembly and installation process, you only need to remove the corresponding fastening bolts to quickly complete the disassembly and installation steps, which is very convenient.

[0007] Preferably, both ends of the support bar are in contact with the limiting plate and the crossbeam respectively, and the shape of the support bar is adapted to the shapes of the first fixing frame and the second fixing frame.

[0008] Through the above technical solution, the design of the support bar of the present application can fit the first fixing frame and the second fixing frame, and has good fit and stability after being fixed.

[0009] Preferably, there are several limit plates located on the left and right sides of the crossbeam, and the crossbeam is in contact with the corresponding limit plates.

[0010] Through the above technical solution, the limiting plate of the present application strengthens the stability of both ends of the beam from both sides, that is, strengthens the stability of the connection between the beam and the longitudinal beam.

[0011] Preferably, a reinforcement bar is fixedly connected to the side surface of the support bar, and one end of the reinforcement bar away from the support bar is in contact with the crossbeam and the limiting plate.

[0012] Through the above technical solution, the reinforcement bar of this application will support the crossbeam and the limit plate after the support bar is fixed. On the one hand, it can enhance the supporting effect of the support bar and ensure that the crossbeam, longitudinal beam and support bar have higher structural strength. On the other hand, it can limit the two ends of the crossbeam to further enhance the stability of the connection between the crossbeam and the longitudinal beam.

[0013] Preferably, the cross section of the reinforcement bar at one end away from the support bar is triangular, and both the reinforcement bar and the support bar are made of high-strength metal.

[0014] Preferably, there are several cross beams which are evenly distributed between the left longitudinal beam and the right longitudinal beam. The first fixing frame is located in the mounting frame, and the width of the second fixing frame is smaller than the width of the cross beam.

[0015] Through the above technical solution, the design of the first fixing frame and the second fixing frame of the present application will not affect the normal installation and subsequent use of the crossbeam and the longitudinal beam.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. The metal frame can support the crossbeam and limit its position through the limiting plate, thereby strengthening the stability of the crossbeam and the stability of the connection between the crossbeam and the longitudinal beam. The design of the support bar can not only strengthen the supporting effect of the crossbeam, but also cooperate with the reinforcement bar to strengthen the stability of the connection between the crossbeam and the longitudinal beam, solving the problems raised in the background technology.
