Energy absorbing equipment for electric vehicle

Abstract

The invention discloses energy absorbing equipment for an electric vehicle. The energy absorbing equipment for the electric vehicle structurally comprises a vehicle door, a vehicle body, an energy absorbing buffering mechanism, wheels and a vehicle head; the vehicle door is arranged on the vehicle body; the wheels are mounted at the bottom of the vehicle body; and the vehicle body is fixedly connected with the vehicle head. According to the energy absorbing equipment for the electric vehicle, as a telescopic threaded sleeve, a damping structure and an auxiliary telescopic structure are arranged, the telescopic threaded sleeve expands and retracts under the assistance of the auxiliary telescopic structure so that the ring number of an annular clamping column is increased and the energy absorbing effect is improved; by using a transmission structure and a synchronous pushing structure, the damping structure is driven to stop the expansion and retraction of the telescopic threaded sleeveso as to realize a secondary energy absorbing effect; the auxiliary telescopic structure is not driven by using an electronic system, but is driven depending on the collision speed of a threaded rod;the higher the collision speed is, the more collisions the vehicle suffers, the higher the sliding speed of the telescopic threaded sleeve is; and therefore, the control reaction time is reduced, thedriving experience restriction is reduced and the safety factor of driving is directly increased.

Description

technical field [0001] The invention is an energy-absorbing device for an electric vehicle, which belongs to the field of energy-absorbing devices for an electric vehicle. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Because the impact on the environment is relatively small compared with traditional cars, its prospects are widely optimistic, but the current technology is not yet mature. The energy-absorbing structures used by some electric vehicles during driving cannot achieve different safe energy-absorbing capabilities at different vehicle speeds to meet the needs of collision safety, and the control of the number of threads is mostly controlled by electronic systems. To control, there is a certain buffer time and the driver's driving experience in judging the speed of the vehicle between this...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an energy-absorbing device for electric vehicles to solve the problem that the existing energy-absorbing structures used in the driving process of electric vehicles cannot achieve different speeds at different vehicle speeds. Safety energy absorption capacity to meet the needs of collision safety, and the control of the number of threads is mostly controlled by an electronic system. There is a certain buffer time between the controls and the driver's driving experience in judging the speed. Once there is a mistake, It cannot be stretched automatically, and the safety factor is not enough
