Energy absorption device with function of protecting pedestrians during collision and method for protecting pedestrians

Abstract

The invention provides an energy absorption device with the function of protecting pedestrians during collision. The energy absorption device is used for absorbing impact energy during collision whena vehicle and the pedestrians are in collision. The energy absorption device comprises a front air window frame and a popup component. The front air window frame is provided with an upper window framebody close to the top of the vehicle. The popup component is arranged to be capable of popped up from the upper window frame body at a preset speed when triggered so as to at least cover front air window glass of the vehicle and the rear edge of an engine cover simultaneously. The popup component is made of a completely-transparent material or a material with the preset transparence and is constructed to be capable of deforming during collision so as to absorb the impact energy during collision. The layer of popup component is additionally arranged on the front portion of a front air window and can at least cover the front air window glass of the vehicle and the rear edge of the engine cover simultaneously when triggered, thus when the vehicle and the pedestrians are in collision, the situation that the heads of the pedestrians impact the hard areas such as the lower middle portion of the front air window glass and the rear edge of the engine cover can be avoided, and thus the harm tothe heads of the pedestrians is relieved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an energy absorbing device for protecting pedestrians during a collision and a method for protecting pedestrians. Background technique [0002] When a vehicle collides with a pedestrian, the windshield is usually the most accessible area for the pedestrian's head. In the area from the lower edge of the front windshield to the rear edge of the hood, due to the greater rigidity of the body structure, it is more likely to cause serious head injuries. And in this area, the probability of a head collision is significantly higher than other positions of the vehicle. [0003] At present, the safety protection scheme for this area is mainly to install pedestrian airbags in this area. When a pedestrian collides with a vehicle, by opening the pedestrian airbag, the head hits the airbag, thereby preventing the head from directly hitting the area from the lower edge of the windsh...

Problems solved by technology

[0004] However, the setting of the pedestrian airbag is only designed for pedestrians of a specific height. If the height is high or short, the airbag cannot effectively protect the head.

In addition, when the airbag is deployed, it will cover most of the front windshield, making the driver's vision worse and increasing the risk of secondary collision with pedestrians
