In one possible embodiment, the protrusion 200 in the embodiment of the present application includes a pin, and the guide rail 100 is provided with a through hole, and the pin is fixed in the through hole. The pin may interact with the first slope 322 or the second slope 323 of the rotation member 320 to generate a relative displacement, and the rotation member 320 rotates because the pin is fixedly connected with the guide rail 100 and the pin does not move.

In one possible embodiment, the present application provides a device comprising a cushioning mechanism according to any of the above embodiments, the device further comprising a first member and a second member, the first member and the second member being connected by the cushioning mechanism.

In some possible embodiments, the device of the present application may be a cabinet, drawer, door or window, etc., for example, the buffer mechanism may be a cabinet door buffer mechanism, the first component may be a cabinet body, and the second component may be a cabinet door. The cabinet body is connected with the cabinet door through a buffer mechanism. The guide rail 100 can be fixed on the cabinet body, and the sliding block assembly 300 is fixed on the cabinet door, so that the cabinet door can be automatically and slowly closed within a final distance in the closing process of the cabinet door. The cabinet door has no rebound or loose closing problem, and no noise is generated at the closing moment.

The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application.
