The embodiment of the utility model provides a shock-absorbing structure 100, as shown in fig. 1 to 8, include: bracket 110, shock pad 120, retaining member and retaining member 140.

As shown in fig. 2, 7 and 8, the bracket 110 is provided with a mounting post 111. As shown in fig. 1, 2, 7 and 8, the shock absorbing pad 120 is configured to fit over the mounting post 111, and an end of the mounting post 111 away from the bracket 110 extends out of the shock absorbing pad 120. The limiter is configured to be mounted between the cushion 120 and the mounting post 111. Retaining member 140 is configured to be threaded onto mounting post 111 and to hold shock absorbing pad 120 such that shock absorbing pad 120 is held in place between retaining member 140 and bracket 110. Furthermore, during the screwing process of the locking member 140, when the limiting member is pressed on the bracket 110, the locking member 140 is screwed, and the compression amount of the shock absorbing pad 120 is a set value (as understood by referring to fig. 7 and 8); that is, during the tightening process of the locking member 140, the shock absorbing pad 120 is compressed in the axial direction, and when one end of the limiting member is pressed against the bracket 110 and the other end is pressed against the locking member 140, the locking member 140 is tightened, and at this time, the compression amount of the shock absorbing pad 120 is a set value.

When the motor provided with the fan blades is subjected to shock absorption, the generated noise is easier to control and smaller.

In an exemplary embodiment, as shown in fig. 7 and 8, the set value is set to 5% to 10% of the axial height of the cushion 120 in an uncompressed state, so that the cushion 120 has higher damping efficiency and better damping effect. The axial height of the cushion 120 is set to a. The set value may be 5 a%; or, the set value may be 7 a%; alternatively, the set value may be 10 a%, etc.; the above can achieve the purpose of the present application, and the purpose of the present application does not depart from the design concept of the present invention, which is not repeated herein, and all should fall within the protection scope of the present application.

In an exemplary embodiment, as shown in fig. 10 and 11, the shock-absorbing structure further includes: the spacers 150 and 150 are arranged to be compressed between the locking member 140 and the shock absorbing pad 120, so that the locking force applied by the locking member 140 is uniformly applied to the shock absorbing pad 120, and the deformation of the shock absorbing pad 120 at each position is consistent, thereby better ensuring the shock absorbing performance of the shock absorbing pad 120.
