Title:
MECHANISM FOR PREVENTING RESONANCE AND NOISE CHANGE OF MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/200531
Kind Code:
A1
Abstract:
A mechanism for preventing resonance and noise change of a motor, comprising a lower housing (10) and an upper housing (20) fixedly connected to the lower housing (10). The upper housing (20) and the lower housing (10) are combined together to form a cavity (100) for accommodating a motor (30); the front end of the lower housing (10) is provided with an elastic sheet (111); the elastic sheet (111) is provided with an arc groove (1111) for positioning a motor shaft (33) of the motor (30); the groove surface of the arc groove (1111) contacts the motor shaft (33). The elastic sheet (111) enables, by means of its own elastic force, the groove surface of the arc groove (1111) to contact the motor shaft (33), so that accurate positioning of the motor shaft (33) is achieved, and the position displacement of the motor shaft (33) is effectively avoided, thereby enabling the motor shaft (33) to work more smoothly, and preventing obvious resonance and large noise under the situation such as a sudden change in the rotation speed.
