Front anti-collision structure of four-wheeler frame

Abstract

The invention belongs to the technical field of vehicles, and provides a front anti-collision structure of a four-wheeler frame. The front anti-collision structure of the four-wheeler frame comprises an outer front face anti-collision part and an inner front face anti-collision part; the outer front face anti-collision part comprises an upper anti-collision part and a lower anti-collision part, the lower anti-collision part is located in front of the upper anti-collision part at the plane position and is provided with two energy absorption pipes I (6) welded to a bottom frame front transverse strutbeam (11), the upper anti-collision part is provided with two energy absorption pipes II (4) welded to a front bumper (3), and a steering wheel supporting structure of the inner front face anti-collision part is connected to a bodywork front transverse strutbeam (9) in the front of the frame. The front anti-collision structure improves full vehicle safety and has the advantages of being compact in structure, small in welding portion number, light in weight and high in overall structure strength.

Description

technical field [0001] The invention belongs to the technical field of vehicles and mainly proposes a front anti-collision structure of a frame of a four-wheel vehicle. Background technique [0002] At present, the anti-collision structure of the low-speed four-wheel vehicle frame is not perfect enough, and the vehicle can only be protected by the bumper at the front of the four-wheel vehicle frame. There is no good collision energy-absorbing structure, so there is no good collision for the members Protective effect; In addition, in the prior art, the steering wheel support of a low-speed four-wheel vehicle is composed of a single rectangular tube, which has a high structural strength but poor frontal crush deformation effect and poor stability. It unloads the force of the steering wheel on the human body very well, resulting in a high displacement damage value of the steering wheel to the human chest, which does not meet the requirements of regulations.
