Problems solved by technology

Although the weight of the full load-bearing body structure is smaller than that of the first two types, it cannot effectively reduce the weight of the body.
[0006] The above three structures are all steel structures, the weight of the whole vehicle is heavy, which leads to a decrease in the carrying capacity, high energy consumption of the bus, and the steel skeleton is prone to rust, even if the skeleton has been phosphated, the life span is only about 8 years, and the Cannot be recycled after rusting
The phosphorus in the phosphating solution is a highly toxic substance, and the antirust paint sprayed on the rectangular steel pipe is also toxic, both of which seriously pollute the environment

Abstract

The invention relates to the field of automotive manufacturing, in particular to an automotive frame component applied to a framework structure of a passenger car. The automotive frame component comprises a square baseboard and a groove arranged on the baseboard, and the baseboard and the groove together form a square hollow tubular structure; riveting holes are respectively arranged on the first and second flanges of the baseboard far away from the hollow tubular structure; and the automotive frame component is made of aluminum alloy or magnesium alloy material. According to the using demand, a supporting rib can be added in the hollow tubular structure, or a flange, parallel to the baseboard, can be added to the side edge of the square hollow tubular structure, which is far away from the baseboard; and the supporting rib and the base board as well as the supporting rib and the side edge far away from the baseboard can be connected by a Y-shaped structure to ensure that the automotive frame component has stronger impact resistance and bending resistance capabilities. As fillet designs are used for the connection between the baseboard and the groove, the connection between the groove and the flange arranged thereon, and other corner parts, the occurrence of cracks caused by over-concentrated local stress is prevented.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a vehicle frame component used for the skeleton structure of a passenger car. Background technique [0002] There are three main types of existing passenger car skeleton structures: [0003] The first type is non-load-bearing. Cars have a rigid frame, also known as a chassis frame. The main body of the vehicle body is suspended on the vehicle frame and connected by elastic elements, mainly relying on the vehicle frame to bear the load, and the vehicle body does not participate in the force bearing. This kind of non-load-bearing body is relatively cumbersome, high in mass, high in the center of mass of the car, and poor in high-speed driving stability. [0004] The second type is semi-loaded. The car with semi-loaded body does not have a rigid frame, but only strengthens the front wall, side wall, rear wall, chassis and other parts. The body and the chassis together for...
