Embodiment 1

[0016] Such as figure 1 As shown, the energy absorbing box body 3 is connected with a front connecting plate 2 for connecting with the front bumper of an automobile and a rear connecting plate 1 for connecting with the front longitudinal beam of the automobile. Such as figure 2 , image 3 As shown, the energy absorbing box body is stepped along the longitudinal direction of the vehicle body. In this embodiment, the energy absorbing box body is stepped along the longitudinal direction of the vehicle body.

[0017] The body of the energy absorbing box is formed by roll extrusion of seamless hollow square steel tubes. The front connecting plate 2 and the rear connecting plate 1 are stamped from steel plates. The rear connecting plate 1 and the energy absorbing box body 3 are welded and installed on the front longitudinal beam of the car by bolts. At the front end, the front connecting plate 2 is welded to the energy absorbing box body 3 and then welded to the front bumper beam.

Embodiment 2

[0019] The energy absorbing box body is in the shape of a three-level step along the longitudinal direction of the vehicle body, and the working principle is the same as that of the first embodiment.

Abstract

The invention relates to a vehicle energy absorption box which has better anti-collision effect. The vehicle energy absorption box is provided with an energy absorption box body with two openings at both ends. The vehicle energy absorption box is characterized in that the vehicle energy absorption box body is arranged in a step shape along the longitudinal direction of a vehicle body.

Description

Technical field [0001] The invention relates to an automobile energy absorbing box. Background technique [0002] In the prior art, such as the technical solution disclosed in the patent (patent number: 200620075281.8) entitled "A kind of energy-absorbing box for automobile subframe", most car models adopt the suction with the inner and outer plates welded together and open at both ends. The energy box, which is connected with the front bumper and the longitudinal beam of the car, is used to prevent injury to personnel in the car when the car collides. The existing energy absorbing box has an insufficient anti-collision effect. Summary of the invention [0003] The purpose of the present invention is to provide an automobile energy absorbing box with better anti-collision effect. [0004] Technical solutions to achieve the purpose of the present invention: [0005] An energy absorbing box for an automobile has an energy absorbing box body with open ends, and is characterized in that...
