Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile frames, and more specifically to a high-strength automobile frame. Background Art
[0002] The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle, and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels.
[0003] Most of the automobile frames currently on the market have the following problems when in use:
[0004] In actual use, the supporting structure of a traditional automobile frame is fixed by direct welding. After a long period of driving, the supporting structure will be deformed. When the frame is maintained later, it is difficult to disassemble the supporting structure for maintenance or replacement, which increases the difficulty of disassembly. In actual use, a small amount of supporting structure is added inside the traditional automobile frame, resulting in a low strength of the frame. In this way, it is difficult to increase the strength of the frame during use. Utility Model Content
