Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

It should be noted that the elastic component 30 abuts against the output shaft 20, so that the elastic component 30 always provides a bounce force to the output shaft 20 (the bounce force direction shown in fig. 1 faces to the right), and when the output shaft 20 tends to axially move due to the vibration of the motor 2, the output shaft 20 drives the self-locking mechanism in the motor 2 to abut against under the bounce force of the elastic component 30, thereby avoiding the self-locking performance of the motor 2 from being reduced or even disabled due to the gap generated in the self-locking mechanism.

This use motor auto-lock auxiliary device of novel embodiment has a bounce-back all the time to the output shaft 20 of motor 2 through the setting of stop part 10 and elastic component 30 to push away tightly the output shaft 20 of motor 2, effectively prevent that output shaft 20 axial from moving, improved motor 2's auto-lock performance.

The stop piece 10 covers the output shaft 20 and the elastic component 30 inside the stop piece 10, so that the self-locking effect and even failure of the output shaft 20 and the elastic component 30 due to external influences (such as collision, friction and blockage) are avoided.

Further, the annular projection abuts against the inner circumferential wall of the stopper 10.

Alternatively, the annular protrusion may be in sliding contact with the inner circumferential wall of the stopper 10, and the annular protrusion may also be in rolling contact with the inner circumferential wall of the stopper 10.
