[0021] The technical solution of the present utility model will be further elaborated in detail below in conjunction with the specification drawings and specific embodiments.

[0022] Embodiment 1:

[0023] A high-damping bushing assembly for a shock absorber provided by the present application includes a shock absorber sleeve 1; a wear-resistant plate 4 is arranged in the inner cavity of the shock absorber sleeve 1, and a fixing mechanism 5 is arranged at equal intervals on the inner side of the shock absorber sleeve 1;

[0024] The fixing mechanism 5 includes a placement cavity 501, an electromagnet 502, a spring 503 and a fixing block 504. The placement cavity 501 is opened in the inner cavity of the shock absorber sleeve 1. One end of the inner wall of the placement cavity 501 is fixedly installed with the electromagnet 502. The spring 503 is fixedly installed inside the placement cavity 501. A spring 503 is slidably installed on one side of the spring 503. Fixing grooves 6 are opened at equal intervals on the surface of the wear-resistant plate 4. The size of the fixing grooves 6 matches the size of the fixing blocks 504. Wear-resistant plates 7 are arranged at equal intervals on the outer side of the shock absorber sleeve 1;

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the device is in use, the user needs to fixedly install the first wear-resistant plate 4 in the inner cavity of the shock-absorbing sleeve 1 for use to improve the wear resistance of the inner wall of the shock-absorbing sleeve 1. At this time, the electromagnet 502 can be energized through an external controller. Then, the magnetic force generated by the energized electromagnet 502 sucks the fixing block 504 into the interior of the placement cavity 501. Then, the user places the first wear-resistant plate 4 into the inner cavity of the shock-absorbing sleeve 1 and aligns the fixing groove 6 with 505. Then, the electromagnet 502 is de-energized through the external controller, and the fixing block 504 will pop out outward under the elastic force of the fixing block 504 inside it. Thus, the first wear-resistant plate 4 can be fixed in the inner cavity of the shock-absorbing sleeve 1 for use to increase the friction force of the inner wall of the shock-absorbing sleeve 1. When the first wear-resistant plate 4 is in use for a long time, it can be disassembled through the fixing mechanism 5. And during the process of replacing the first wear-resistant plate 4, the user does not need to use external tools for disassembly and installation. Therefore, the convenience and working efficiency of the user for disassembling and installing the first wear-resistant plate 4 can be improved to a certain extent.

[0026] Further, installation grooves 2 are symmetrically formed in the inner cavity of the shock-absorbing sleeve 1, and sealing covers 3 are symmetrically arranged inside the shock-absorbing sleeve 1. An installation block 301 is fixedly installed on the outer side of the sealing cover 3.

[0027] Specifically, as Figure 1 、 Figure 2 shown, when the user installs the shock-absorbing sleeve 1 and the shock-absorbing mechanism, the user passes both ends of the shock absorber through the inner cavity of the sealing cover 3 and then places them inside the shock-absorbing sleeve 1. At this time, the user snaps the installation block 301 into the inner cavity of the installation groove 2, and the shock-absorbing sleeve 1 and the shock absorber can be connected as a whole for use.

[0028] Further, a heat dissipation mechanism 8 is arranged in the inner cavity of the shock-absorbing sleeve 1. The heat dissipation mechanism 8 includes a placement groove 801, a semiconductor refrigeration sheet 802, and a heat conduction plate 803. The placement groove 801 is formed in the inner cavity of the shock-absorbing sleeve 1, the semiconductor refrigeration sheet 802 is installed inside the placement groove 801, and the heat conduction plate 803 is arranged on the outer side of the semiconductor refrigeration sheet 802.

[0029] Specifically, as Figure 1 、 Figure 2 shown, when the shock absorber is in use in the inner cavity of the shock-absorbing sleeve 1, the shock absorber will slide in the inner cavity of the shock-absorbing sleeve 1. During the sliding process, a large amount of heat is generated by the friction between the shock absorber and the first wear-resistant plate 4. At this time, the semiconductor refrigeration sheet 802 can be energized through the controller. Then, the cool air generated after the semiconductor refrigeration sheet 802 is energized is introduced to the surface of the first wear-resistant plate 4 through the heat conduction plate 803 to cool and dissipate the heat inside the shock-absorbing sleeve 1 and the first wear-resistant plate 4. Thus, the service life of the shock-absorbing sleeve 1 and the first wear-resistant plate 4 can be increased to a certain extent.

[0030] Working principle: The user needs to fixedly install the first wear-resistant plate 4 in the inner cavity of the shock-absorbing sleeve 1 for use to improve the wear resistance of the inner wall of the shock-absorbing sleeve 1. At this time, the electromagnet 502 can be energized through an external controller. Then, the magnetic force generated by the energized electromagnet 502 will suck the fixing block 504 into the interior of the placement cavity 501. Then, the user places the first wear-resistant plate 4 into the inner cavity of the shock-absorbing sleeve 1 and aligns the fixing groove 6 with 505. Then, the electromagnet 502 is powered off through the external controller, and the fixing block 504 will pop out outward under the elastic force of the fixing block 504 inside it. Furthermore, the first wear-resistant plate 4 can be fixed in the inner cavity of the shock-absorbing sleeve 1 for use to increase the friction force of the inner wall of the shock-absorbing sleeve 1.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
