front-end collision protection system

Abstract

Provided is a crashing protection system of the front end of a vehicle body. The crashing protection system comprises a support of the front end of the vehicle, a bumper buffering beam, a shank protection beam and a thigh protection device. The bumper buffering beam, the shank protection beam and the thigh protection device are connected to the support of the front end of the vehicle body, the shank protection beam is arranged below the bumper buffering beam, the thigh protection device is arranged above the bumper buffering beam, the thigh protection device comprises at least one thigh protection beam, and the two ends of the thigh protection beam are connected to the support of the front end of the vehicle body. According to the crashing protection system of the front end of the vehicle body, the system can provide support for the thigh of a pedestrian during the crashing process, reduce the bent angle of the knee of the pedestrian during the crashing process between the vehicle and the pedestrian, the situation that the pedestrian suffers from harms of fracture and the like is avoided, and the crashing performance of the vehicle can be remarkably improved at the same time.

Description

technical field [0001] The invention relates to the field of automobile safety protection, in particular to a collision protection system for the front end of a vehicle body. Background technique [0002] In recent years, the automotive industry has increasingly considered the issue of how to protect pedestrians in the event of an accident. Reducing the risk of injury from collisions between cars and pedestrians has grown in importance over the years. [0003] At present, the protection of the calf collision in pedestrian protection is generally improved by improving the front bumper structure of the vehicle, adding upper and lower protection brackets for the calf, and providing support for the calf together with the front edge of the hair cover. In a pedestrian collision accident, the lower leg of the pedestrian is usually hit first. At this time, the protective bracket under the lower leg and the buffer foam of the front bumper will provide support for the lower leg of th...

Problems solved by technology

However, for large SUV models, due to the high cabin height, the front edge of the hood is higher than the thighs, which cannot provide support for the thighs. Due to space constraints, the traditional lower leg protection bracket can only be placed under the front grille. During the collision process between the vehicle and the pedestrian, the front grille does not have enough support for the thigh, which may easily cause the dynamic bending angle of the pedestrian's knee joint to be too large, which in turn increases the probability of the pedestrian's leg bone fracture, resulting in the lower leg collision performance of the car.
