Description

an energy absorber

technical field

The invention relates to the technical field of automobile interior impact energy absorption, in particular to an energy absorber.

Background technique

With the continuous improvement of automobile safety requirements, in passenger cars and other vehicles, in the event of a collision accident, it is necessary to minimize the injury to the driver and passenger. Therefore, it is necessary to consider the high possibility of injury to the driver and passenger. An energy absorber for absorbing energy is arranged in the interior part of the area and the space between the interior part and the inner and outer sheet metal parts of the vehicle body. When a collision accident occurs, the driver and occupant are in contact with interior parts, and the energy absorber is used to reduce the impact load on the occupant, thereby reducing the injury index to the driver and occupant.

The absorber is made of resin synthetic material, which consists of a base and a plurality of independent sub-units, which are assembled together by means of snap-fit. By adjusting the data of the sub-units, it can adapt to the optimal adjustment of the impact force of a single item, and many more. Switching applications across projects can reduce the verification and development cycle, and its sub-units have the characteristics of recycling.

In this way, when the vehicle is in a side collision, the inner and outer door panels are deformed into the vehicle, and the absorber applies a load in the axial direction between the door panel and the door inner and outer panels and then gently collapses and deforms, so as to fully absorb the collision energy and reduce the risk of collision. The damage value of the occupant.
