A shock absorption device for electric vacuum pump of new energy vehicle

Abstract

The invention relates to the technical field of shock absorption for new energy vehicles, in particular to a shock absorption device for an electric vacuum pump of a new energy vehicle. The shock absorbing device of the electric vacuum pump of the new energy vehicle includes an annular sleeve, a fixed flange is fixedly sleeved on the pipe wall, and a through cavity is arranged in the annular sleeve to penetrate the bottom of the pipe body; the protection part is located in the annular sleeve a through cavity opened at the bottom of the sleeve, and the protection component includes a protection tube, the bottom of the protection tube is fixedly fitted in the through cavity opened by the annular sleeve, and an organ-shaped elastic airbag and a decomposition agent are installed in the protection tube ; The buffer part is located on the upper surface of the annular sleeve. The shock absorbing device of the electric vacuum pump of the new energy vehicle provided by the present invention has a built-in protective component that makes the organ-shaped elastic airbag rapidly expand and can quickly cover the shell of the electric vacuum pump, effectively protecting the electric vacuum pump and reducing the collision caused by the electric vacuum pump. Or the problem that the casing is damaged due to severe vibration.

Description

technical field [0001] The invention relates to the technical field of shock absorption for new energy vehicles, in particular to a shock absorption device for an electric vacuum pump of a new energy vehicle. Background technique [0002] At present, the energy storage of new energy vehicles (gas-electric hybrid vehicles and pure electric vehicles) requires the use of high-performance power batteries. New energy vehicles are driven by electric motors and cancel the traditional engine, so they lose the source of vacuum, that is, they cannot provide power for the vehicle. The brake master cylinder provides vacuum booster, and the electric vehicle vacuum booster pump is created to make up for this deficiency. It uses on-board power supply to provide power, pushes the motor on the pump body to move the piston to generate vacuum, and provides the only and reliable vacuum for the hydraulic braking system of various models such as electric vehicles, hybrid vehicles, electric sights...

AI Technical Summary

Problems solved by technology

[0003] Most of the damping devices used in the existing electric vacuum pumps of new energy vehicles only use a single spring damping structure to reduce the vibration amplitude of the electric vacuum pump due to the bumping of the car body. , the spring damping structure cannot effectively protect the electric vacuum pump, and because the pump body does not have a protective structure, the surface is easily damaged, and if the protective structure is installed outside the electric vacuum pump in advance, it will easily lead to poor heat dissipation and heavy structure of the electric vacuum pump
