The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
In order to solve the shortcoming of automobile rear anti-crash beam crashworthiness difference in the prior art, the utility model provides a kind of vehicle rear anti-crash beam assembly, and is as shown in Figure 1, and the vehicle rear anti-crash beam assembly of the utility model comprises:
The rear bumper collision prevention girders 1 that is a few font structures along the cross-sectional plane of vehicle body horizontal expansion; And,
Be used for said rear bumper collision prevention girders 1 is installed in the mounting structure 2 on the vehicle body, be connected on the rear bumper collision prevention girders 1;
Has the groove structure 11 that bumps energy after being used to absorb on the rear bumper collision prevention girders 1.
The vehicle rear anti-crash beam assembly cross-sectional plane of the utility model is a few font structures; When bumping, can form once buffering, and the groove structure 11 that is arranged on the rear bumper collision prevention girders 1 can form secondary buffer; Thereby collision energy is being carried out again collision energy being passed to body bottom section behind the secondary buffer energy-absorbing; The rear anti-crash beam that is a few font structures with traditional cross-sectional plane is compared, and the vehicle rear anti-crash beam assembly intensity of the utility model is higher, bumps the energy of generation after especially when automobile rear meets with collision, more effectively absorbing; Effectively reduce the impact of collision, play good crashworthiness automobile and occupant.
A few font structures of rear bumper collision prevention girders 1 are made up of two sides 1a and the end face 1b that is arranged between the 1a of two sides; Since the end face 1b of a few font structures in practical application towards body exterior; The collision energy of when bumping, generally receiving is maximum, therefore, and in the utility model preferred embodiment; As depicted in figs. 1 and 2, groove structure 11 is formed on the end face 1b of rear bumper collision prevention girders 1.Certainly, in practical application, groove structure 11 also can be arranged on the two sides 1a of rear bumper collision prevention girders 1.
