Abstract
The utility model relates to a passenger car direct impact energy absorption structure. The passenger car direct impact energy absorption structure comprises a bumper and two longitudinal members. Two front ends of the longitudinal members are connected together through a frame cross member. The bumper is located in front of the longitudinal members and the vehicle frame cross member and fixedly connected to the longitudinal members. A cross beam energy absorption box is fixedly arranged in a space which is right between the bumper and the frame cross member. The spaces between the bumper and the two longitudinal members are both provided with longitudinal beam energy absorption boxes. The passenger car direct impact energy absorption structure makes full use of the space in the front of a passenger car. When the passenger car is crashed, the bumper and the energy absorption boxes are squashed and deformed one after another to achieve the gradual model crash energy absorption and reduce the crash energy born by a car body frame, and therefore when the passenger car is crashed, the hurt to a driver and passengers is reduced, and the passive safety performance of the passenger car is greatly improved. The utility model further relates to the passenger car with the direct impact energy absorption structure.
