Preferably, the damping mechanism 4 further includes a guide rod, a lower end of the guide rod is fixedly connected to an upper end surface of the pressed push rod 404, the guide rod penetrates into the spring 402, and a gap is reserved between an upper end of the guide rod and a lower end surface of the stressed carrying substrate 401; through setting up the guide arm, when the pressure push rod 404 received external force, it is right the compression direction of spring 402 leads, strengthens damper 4's stability, simultaneously the upper end of guide arm with reserve the clearance between the lower terminal surface of atress carrying substrate 401, be used for guaranteeing spring 402 because of when the pressure push rod 404 received external force and compressed, the upper end of guide arm can not be strikeed the lower terminal surface of atress carrying substrate 401.
The mounting manner of the shock absorbing mechanism 4 in the fender assembly includes but is not limited to: as shown in fig. 5 and 6, in this embodiment, the damper mechanism 4 further includes an extension positioning plate 405, one side of a lower end surface of the extension positioning plate 405 is fixedly connected to a top end of the slide adjusting carrier block 30201, and the other side of the lower end surface of the extension positioning plate 405 is fixedly connected to an upper end surface of the force-receiving carrying substrate 401.
When the fender 5 is not subjected to an external force, the spring 402 is in an equilibrium state or a slightly compressed state, and the lower end surface of the pressed push rod 404 is in contact with the fender 5.
When fender 5 receives external force, partly atress passes through the contact of pressurized push rod 404 with fender 5, will receive the atress through pressurized push rod 404 is in push down the inside slip extrusion of guide block 403 extremely spring 402 department utilizes the elasticity potential energy that spring 402 compressed the back production after receiving pressure accomplishes the elasticity of fender 5 part atress and offsets to accomplish the elastic support to fender 5, realized right fender partial atress in the use offsets, prolongs the technical effect of the life of fender.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
