Abstract

The invention provides an energy absorption box. The energy absorption box comprises a mounting frame, an energy absorption component and an adjusting component. Mounting space extending in the length direction of the mounting frame is arranged on the mounting frame, and the energy absorption component comprises a first friction portion and a second friction portion; the first friction portion and the second friction portion are both mounted in the mounting space; the second friction portion moves in the length direction of the mounting frame and is in friction contact with the first friction portion to absorb energy; and the adjusting component is arranged on the mounting frame to adjust the friction degree between the first friction portion and the second friction portion. The rigidity of the energy absorption box is adjustable, and the energy absorption box is good in buffer effect and long in service life.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more specifically, relates to a crash box. Background technique [0002] At present, the main structural form of the energy-absorbing box for passenger cars on the market is the fixed cavity type, which is to change the stiffness of the energy-absorbing box by adjusting the cross-sectional structure and material of the energy-absorbing box, so as to achieve the energy-absorbing effect. [0003] The stiffness of the passenger car energy-absorbing boxes on the market mentioned above has been determined at the design stage. During the collision process, due to the different collision speeds and collision angles when the accident occurs, the amount of energy to be absorbed is different. The rigidity of the energy-absorbing box is too large during the collision, the collapse of the energy-absorbing box is not sufficient, the cushioning effect is not ideal, and the collapsed energy-absorbing bo...
