Abstract
The utility model relates to a vehicle bumper, which comprises a channel steel-shaped cross beam and a left and a right telescopic rods arranged in telescopic sleeve barrels. The overhanging ends of the telescopic rods are respectively hinged with both ends of the cross beam. The top ends of two sets of sleeve barrels are mutually hinged. The other end of each sleeve barrel is hinged with a supporting rod whose the other end is hinged with the pin shaft of the middle part of the cross beam. A leading screw penetrates through a nut support frame whose top end is hinged with the pin shafts of the top ends of the sleeve barrels is fixed on the cross beam. The nut is fixedly connected with a driving wheel. The structure that the top side of the bumper protrudes into a triangle of utility model can change the direction of the impact force, and can cause the sub force perpendicular to a vertical head to be smaller than that of the original impact force. Thereby, the damage of a vehicle body and the passengers in the vehicle can be reduced.
