An electric vehicle braking energy regeneration device

Abstract

The invention discloses a braking energy regeneration device for an electric vehicle, which comprises a brake disc, a power storage seat, a fixed frame, a limit seat and a transmission shaft. A turntable is arranged on the transmission shaft, and a There is a fixed frame, the inner side of the fixed frame is equipped with a first rotating shaft through a one-way bearing, and the first rotating shaft at the same vertical plane position of the rotating disc is provided with a brake disc matched with the rotating disc, one side of the braking disc The outside of the first rotating shaft is equipped with a power storage seat through a bearing. In the present invention, the distance between the power storage seat and the limit seat is consistent with the distance between the brake disc and the turntable, and a brake pad matched with the power storage seat is provided inside the space limit seat, so that the brake pads can be used in the manufacturing process. In the process of moving, the brake pad inside the limit seat is in contact with the outer wall of the power storage seat to facilitate the braking of the car, and the rotation of the power storage seat can be limited during the braking process of the power storage seat, so that the The second rotating shaft can drive the power storage spring inside the power storage seat to rotate at a certain angle to store power.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a braking energy regeneration device for electric vehicles. Background technique [0002] Electric vehicle (BEV) refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional vehicles, its prospects are widely optimistic, but the current technology It is still immature. Due to the constraints of battery technology, the driving range of pure electric vehicles is relatively short. When driving on urban roads, vehicles need to start and stop continuously. Every time they brake, they need to consume a certain amount of energy, which is not conducive to improving pure electric vehicles The driving ability of electric vehicles. [0003] At present, during the driving process of the existing electric vehicles,...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a braking energy regeneration device for an electric vehicle to solve the problem that the electric vehicle often performs braking to maintain the safe driving of the electric vehicle during the driving process proposed in the above background technology, and during the braking process Among them, most of them are slightly braked and slightly adjusted the speed to avoid obstacles or perform steering operations. The braking time is short, the instantaneous loss of vehicle braking energy is large, and the electric energy generated by braking energy recovery is small. Repeatedly will generate Charging electric energy into the battery is easy to cause damage to the battery, and increases the weight of the car, which is not conducive to improving the endurance of the car. After braking, it needs to use a large amount of electric energy to provide kinetic energy for the car when it needs to accelerate to an appropriate speed. Energy recovery is relatively difficult. Low, can not achieve the effect of charging and using, and there is a problem of low energy recovery rate
