Vehicle collision energy-absorbing device and method based on elastic broken tooth base

Abstract

The invention discloses a vehicle collision energy absorption device based on an elastic broken tooth base and belongs to the technical field of vehicle front longitudinal beam collision energy absorption. The vehicle collision energy absorption device comprises a broken tooth energy absorption device, a shock absorption device and an elastic energy absorption device. When a vehicle is crashed, energy generated due to collision is firstly transmitted to the broken tooth energy absorption device, the energy is absorbed through the broken tooth energy absorption device at the first level, and the stage has the beneficial effects that rigidity is small, and the energy absorption amount is large. The energy which cannot be absorbed by the broken tooth energy absorption device is transmitted tothe next step, the energy is absorbed through the shock absorption device at the second level, and the stage has the beneficial effects that the energy absorption amount is large, and flexibility islarge. The energy which cannot be absorbed by the shock absorption device is transmitted to the elastic energy absorption device and absorbed through the elastic energy absorption device at the thirdlevel, and the stage has the beneficial effects that flexibility is large so that personal safety can be well protected after the vehicle is crashed, and damage to other components of the vehicle is reduced as much as possible.

Description

technical field [0001] The invention belongs to the technical field of vehicle front longitudinal beam collision energy absorption, and in particular relates to a vehicle collision energy absorption device based on an elastic broken tooth base and a method thereof. Background technique [0002] With the continuous development of social economy, cars have been popularized in people's daily life. Due to the increase of car ownership, traffic safety has become the focus of people's attention. When traffic accidents occur, it often causes casualties. To reduce the damage caused by the collision to the occupants in the car, a collision energy-absorbing device is installed in the car. [0003] At present, the impact energy absorbing device of the front longitudinal beam of the vehicle is usually used to reduce the damage to the occupants of the vehicle. The impact energy absorbing device of the front longitudinal beam of the vehicle has poor anti-collision energy absorption effect...
