Title:
NONLINEAR SPRING CONNECTING STRUCTURE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/000072
Kind Code:
A1
Abstract:
The present utility model provides a nonlinear spring connecting structure and a motor. The nonlinear spring connecting structure comprises a stator, a rotor, and an elastic connecting piece arranged between the stator and the rotor; the elastic connecting piece comprises a first end portion connected to the stator, a second end portion connected to the rotor, and at least two transition connecting portions connected between the first end portion and the second end portion; the at least two transition connecting portions extend from the first end portion to the second end portion in a volume decreasing trend. According to the present utility model, the elastic connecting piece is arranged between the stator and the rotor, and in specific application, the elastic connecting piece provides, by means of deformation thereof, restoring force for the rotor in a moving process so that the rotor makes nonlinear motion relative to the stator. Therefore, the nonlinear spring connecting structure is simpler and the manufacturing cost of the nonlinear spring connecting structure is reduced.
