Title:
ENERGY STORAGE BRAKING DEVICE FOR MOTOR, AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2022/156108
Kind Code:
A1
Abstract:
The embodiments of the present disclosure provide an energy storage braking device for a motor, and an aircraft. The energy storage braking device for a motor comprises a motor assembly and a coupling; the motor assembly comprises a motor, the output shaft of the motor is arranged at the output side of the motor assembly, an end face of the motor assembly is provided with a sliding groove, a spring is provided in the sliding groove; and one end of the coupling is sheathed on the output shaft and can rotate with the output shaft, and the other end of the coupling moves in the sliding groove and can compress the spring on the basis of the rotation of the output shaft. The energy storage braking device for a motor provided in the embodiments of the present disclosure can be widely applied to situations where a motor rotates in a reciprocating manner, the kinetic energy generated in the stroke of the end portion of a coupling connected to the motor compressing a spring is stored, the elastic potential energy is converted into the kinetic energy for the rotation of the motor during the releasing process of the spring, and the motor can be braked at the end of the reciprocating rotation, i.e. at the limit position of the compression of the spring, and quickly achieve rotation in the reverse direction, meeting the requirements for high-frequency reciprocating rotation of the motor, and saving energy.
