Automobile front bumper structure for enhancing pedestrian safety protection

Abstract

The invention provides an automobile front bumper structure for enhancing pedestrian safety protection, which is applied to the technical field of motor vehicle bodies. The automobile front bumper structure for enhancing the pedestrian safety protection comprises a front bumper cross beam (1), wherein the upper end part of the front bumper cross beam (1) is connected with a water tank upper cross beam (2); the front bumper cross beam (1) is also connected with a front bumper skin (2); the front bumper skin (2) is connected with a front bumper lower end plate (3); the front bumper lower end plate (3) is connected with a water tank lower cross beam (4); and a buffering foam (5) is arranged in the front bumper skin (2). Through the adoption of the automobile front bumper structure provided by the invention, the front bumper lower end plate and the buffering foam in the front bumper can simultaneously have an effect of protecting shanks of pedestrians when the pedestrians comes into collision with the automobile front bumper, so as to ensure that the shanks of the pedestrians cannot invade into the lower part of the front bumper, avoid overlarge bending angles of the shanks of the pedestrians and protect the shanks of the pedestrians against being damaged.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle bodies, and more specifically relates to an automobile front protection structure for improving the safety protection of pedestrians. Background technique [0002] With more and more vehicle-to-person collision accidents in the current society, the importance of pedestrian protection is increasingly recognized by everyone. The front body of the car is equipped with a bumper, and the huge impact force is alleviated as much as possible through the deformation of the bumper. The upper end of the bumper is fixed to the upper beam of the water tank, and the lower end is fixed to the lower beam of the water tank. Generally, the front bumper beam of a car is located in the middle of the bumper, and the front part is equipped with cushioning foam, so that the impact force on the pedestrian's calf can be buffered in the event of a collision. Generally, the stiffness of the lower part of the front bu...

Problems solved by technology

The upper end of the bumper is fixed to the upper beam of the water tank, and the lower end is fixed to the lower beam of the water tank. Generally, the front bumper beam of a car is located in the middle of the bumper, and the front part is equipped with cushioning foam, so that the impact force on the pedestrian's calf can be buffered in the event of a collision. Generally, the rigidity of the lower part of the front bumper is relatively soft. During a collision, the lower part of the lower leg will invade the lower part of the front bumper, causing the lower leg to bend too much and causing damage to the lower leg.
