Furthermore, the energy absorption buffer plate is made of polypropylene plastics.

By adopting the technical scheme, the polypropylene plastic is a common buffer material on the automobile bumper and is mainly used for improving the buffer performance of the automobile bumper.

Furthermore, keep away from on the shell there is air intake grille under the anticollision billet through bolted connection.

By adopting the technical scheme, the air inlet grille is mainly used for ensuring the circulation of air in the vehicle body.

Furthermore, fog lamp mounting holes are formed in the two sides, far away from the air inlet grille, of the shell.

Through adopting above-mentioned technical scheme, the fog lamp mounting hole can make the fog lamp pass, the installation of this bumper of being convenient for.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

for solving current car front bumper mainly adopt the crossbeam to carry out the anticollision and support, the support rigidity is relatively poor, and its characteristics that mainly rely on buffer material itself realize the anticollision buffering, and the bumper damages the risk great when the striking, the shorter problem of life, the utility model discloses a design of buffer cap, spring and anticollision billet not only can increase the support rigidity of this bumper for the buffering crashworthiness of bumper obtains promoting moreover, effectively reduces the risk that the bumper damaged, improves bumper life.
