[0002] The current electric vehicles have a short cycle life of deep discharge of power batteries, long charging time, low specific power, low specific energy, and short driving range. The improvement of driving range has a profound impact on the development of electric vehicles. During the deceleration and braking process of electric vehicles, a large amount of kinetic energy is converted into heat energy and dissipated. Under the current performance level of power batteries, this kinetic energy can be recycled through regenerative braking to increase the driving range of the vehicle.

[0003] According to a Chinese patent with the announcement number "CN211075546U", a brake energy regeneration device for electric vehicles is disclosed, which includes a rotating shaft, a sleeve, a first coil spring and a second coil spring; rotating plates are fixedly sleeved at both ends of the rotating shaft, and a limit slide for slidingly abutting against the rotating shaft is extended from the inner wall of the sleeve, and the rotating shaft is movably inserted into the limit slide, and the limit slide is provided with a sliding groove for rotating in cooperation with the rotating plate, and a plurality of balls are evenly distributed and rollingly provided on the end surfaces of both sides of the rotating plate, and the plurality of balls are slidingly abutted against the inner wall of the sliding groove. The utility model has a novel structure and an ingenious design, and improves the traditional brake energy regeneration device for electric vehicles, and can limit the rotating plate to ensure that the rotating shaft is not easily offset or loosened during rotation, reduce the friction between the inner wall of the sliding groove and the rotating plate, improve the smoothness of sliding, and ensure the reliability and stability of the rotation of the rotating shaft;

[0004] It can be seen from the above structure that by setting a plurality of ball bearings, the friction between the inner wall of the sliding groove and the rotating sheet is reduced, the smoothness of sliding is improved, and the reliability and stability of the rotation of the rotating shaft are guaranteed. When installing the rotating shaft and the transmission shaft, an external screw is passed through the installation screw hole and the fixing screw hole and screwed with the two to achieve a fixed connection between the transmission shaft of the electric vehicle and the rotating shaft, which is easy to use. When the rotating shaft and the transmission shaft are directly screwed, the screws are likely to loosen due to the vibration generated when the car is riding. Utility Model Content
