Abstract

The invention discloses a three-section front end structure with a function of flexible leg type collision. The structure comprises an upper framework, a middle energy absorption structure and a guideplate, the upper framework is arranged on the upper portion of the middle energy absorption structure, the guide plate is arranged on the lower portion of the middle energy absorption structure, theupper framework comprises an energy absorption structure A, and the guide plate comprises an energy absorption structure B. The provided three-section front end structure with the function of flexibleleg type collision has the advantages that a three-section pedestrian protection structure can protect pedestrian legs to the maximum extent under existing space, the invasion to vehicles during thelow-speed collision can be reduced, and the pedestrian protection and the low-speed collision are balanced.

Description

technical field [0001] The invention relates to an automobile front end structure, in particular to a three-stage front end structure for a flexible leg type collision. Background technique [0002] According to the principle of energy conservation, when a pedestrian collides with a moving vehicle, part of the energy of the car will be absorbed through the deformation of the front of the car, and part of the energy will be directly transmitted to the pedestrian. If the front structure of the vehicle cannot absorb energy or the energy absorption effect is not good, pedestrians will be seriously injured; a large number of studies have shown that the shape of the car and the rigidity of the internal structure are key factors affecting the protection effect of automobile pedestrians. Contents of the invention [0003] The present invention aims to provide a three-segment front end structure for flexible leg-type collisions, and a three-segment pedestrian protection structure, ...
