Title:
COMPOSITE-MOTION ELECTRIC MOTOR HAVING ELASTIC BEARING PEDESTAL, AND ELECTRIC TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2023/245734
Kind Code:
A1
Abstract:
Provided in the present invention is a composite-motion electric motor having an elastic bearing pedestal, characterized in that the electric motor comprises an electric motor shaft, a bearing sleeved on the electric motor shaft, an elastic bearing pedestal sleeved on the bearing, a rotary drive portion, and a linear drive portion, wherein the elastic bearing pedestal comprises a fixed portion, a bearing connecting portion connected to the bearing, and an elastic movable portion connected to the fixed portion and the bearing connecting portion; the rotary drive portion comprises a rotary drive portion stator and a rotary drive portion rotor, and the rotary drive portion rotor is connected to the electric motor shaft; and the linear drive portion comprises a linear drive portion stator and a linear drive portion mover, and the linear drive portion mover is connected to the electric motor shaft. According to the present invention, the free motion of the electric motor shaft in an axial direction is achieved by means of the elastic bearing pedestal, so that the rotary drive portion cooperates with the linear drive portion to achieve a composite motion of the electric motor shaft in a rotation direction and a linear direction.
