Automobile body front structure and automobile

Abstract

The invention relates to an automobile body front structure and an automobile, and belongs to the field of automobiles. The vehicle body front structure comprises a front bumper, an energy absorptionbox, an energy absorption box connecting plate, a first front longitudinal beam and an angle brace component.The front bumper extends in a first direction. One end of the energy absorption box is connected with the end part of the front bumper. The energy absorption box connecting plate is provided with a first surface and a second surface which are oppositely arranged, and the first surface of the energy absorption box connecting plate is connected with the other end of the energy absorption box. The first front longitudinal beam extends in the second direction and is connected with the second surface of the energy absorption box connecting plate. The angle brace component is provided with a cavity, one end of the angle brace component is connected with the second surface of the energy absorption box connecting plate, and the other end of the angle brace component is connected with the first front longitudinal beam. Due to the existence of the angle brace component, on the basis of energy absorption of the energy absorption box, the angle brace component can also absorb part of energy, the loading force transmitted to the first front longitudinal beam is further reduced, and the energy absorption effect of the vehicle body front structure is improved.

Description

technical field [0001] The present disclosure relates to the field of automobiles, in particular to a vehicle body front structure and the automobile. Background technique [0002] The front structure of the car body can absorb energy during a car collision, reduce the load force transmitted to the passenger compartment, and reduce the possibility of occupant injury. [0003] The front structure of the vehicle body includes a front bumper, a front longitudinal beam, and an energy-absorbing box connecting the bumper and the front longitudinal beam. The extension directions of the front bumper and the front longitudinal beam are perpendicular to each other. When the car collides, the front bumper transmits the load force to the energy-absorbing box. After the energy-absorbing box collapses and deforms, the load force is reduced, and then the load force is transmitted to the front longitudinal beam, and the front longitudinal beam then transmits the load force to the occupant. ...

AI Technical Summary

Problems solved by technology

However, the energy absorption effect of the front structure of the car body is still not good enough, and it is easy to cause the driver to be injured in the event of a collision.
