A front collision protection structure for passenger cars with low driving area

Abstract

The invention relates to a frontal collision protection structure for a low-drive-zone passenger car. The frontal collision protection structure comprises a front anti-collision beam, a left vertical beam, a right vertical beam, a rear rigidity section beam, a plurality of energy absorption beams, a left stiffening beam and a right stiffening beam, wherein the front anti-collision beam is convex forwards and in an arc shape; the left vertical beam and the right vertical beam are arranged on the rear side of the left end and the rear side of the right end of the front anti-collision beam correspondingly; the rear rigidity section beam is connected between the left vertical beam and the right vertical beam; the multiple energy absorption beams are connected between the rear side wall of the front anti-collision beam and the front side wall of the rear rigidity section beam; and the left stiffening beam and the right stiffening beam are connected to the rear side of the left vertical column and the rear side of the right vertical column correspondingly. The energy absorption beams are cavities provided with a plurality of crushing induction grooves sequentially formed in the front-back direction. By means of the frontal collision protection structure for the low-drive-zone passenger car, not only can the front end of the passenger car resist impact, but also the passenger car can have enough buffer force to reduce passenger injuries when encountering frontal collision, and a living space for passengers in the first row is ensured.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a front collision protection structure of a passenger car in a low driving area. Background technique [0002] At present, most of the existing domestic passenger car collision protection devices are aimed at protecting the driver during a frontal collision. As for the low-driving zone passenger cars that occupy a relatively large share in the large-scale passenger transport market, the first row of passengers on the upper part is located at the front end of the bus, and the strength of this position is relatively weak. In the event of a frontal collision, the safety of the first row of passengers Can not guarantee. Contents of the invention [0003] The object of the present invention is to provide a front collision protection structure for a passenger car in a low driving area. This structure not only enables the front end of the passenger car to withstand impact, but...
