Problems solved by technology

[0004] The structure of the existing automobile bumper is generally installed on the front of the automobile frame, a slightly curved channel-shaped steel plate. The defect of this structure is that once the automobile collides with other vehicles or objects during driving, the bumper has no buffer. Function, its impact force produces a 1:1 impact effect, not only causing damage to the object being hit, but also causing damage to the driver and the vehicle itself

Abstract

The invention discloses an automotive front bumper system which comprises a bumper cross beam, a buffer energy-absorbing block, an auxiliary bumper reinforcing plate and bumper outer skin. The bumper cross beam is of a metal structure and is welded and connected to an automobile frame. The front end of the auxiliary bumper reinforcing plate is connected with the bumper outer skin through a fastener, and the rear end of the auxiliary bumper reinforcing plate is installed at the bottom of a water tank support through bolts. The bumper outer skin is arranged on the outer side of the buffer energy-absorbing block and is of an integral structure, the front end faces of the upper portion and the lower portion are located on the same cross section, the front end face of the auxiliary bumper reinforcing plate and the front end face of the buffer energy-absorbing block are located on the same cross section, and the buffer energy-absorbing block is installed in the cavity between the bumper outer skin and the bumper cross beam. The automotive front bumper system can effectively decrease lower limb injuries of pedestrians during person-vehicle collision.

Description

technical field [0001] The invention relates to an automobile bumper, in particular to an automobile front bumper system. Background technique [0002] In recent years, with the increase of traffic safety awareness, the frequency of road traffic accidents in China has decreased, but the total number of casualties caused by traffic accidents is still very large. According to statistical analysis, in all road traffic accidents, pedestrian casualties account for about 20% of the total casualties; among them, the frequency of lower limb injuries is second only to head injuries. [0003] In the process of human-vehicle collision, the front bumper of the automobile is the main structure that causes the injury of pedestrian's lower limbs. In the event of an accident, the pedestrian's calf or knee joint area first directly collides with the bumper, the tibia bears the direct impact force, and due to the delay in the movement of the femur, the knee joint area bears shear loads as we...
