[0028] The fixed ring 21 is respectively fixedly connected to the outer side of the bracket body 11 and the outer position of one end of the dust cover 13. The fixed block 22 is fixedly connected to both sides of the fixed ring 21. The first fixed shaft 23 is fixedly connected to the inner position of the fixed block 22. One end of the connecting plate 24 is sleeved on the outer surface of the first fixed shaft 23. The support shaft 25 is sleeved on the inner position of the other end of the connecting plate 24. One end of the link 26 is sleeved on the outer surfaces of both ends of the support shaft 25. The second fixed shaft 27 is sleeved on the other end of the link 26. The retaining ring 28 is fixedly connected to the outer side of the fixed ring 21;

[0029] The fixed ring 21 is used to support the fixed block 22. The fixed block 22 is respectively used to support the first fixed shaft 23 and the second fixed shaft 27. The first fixed shaft 23 and the second fixed shaft 27 are respectively used to support one end of the connecting plate 24 and one end of the link 26. The support shaft 25 is used to support the other end of the connecting plate 24 and the other end of the link 26. The retaining ring 28 is used to scrape the outer surface of the guide post 12;

[0030] The bracket assembly further includes a guide post 12;

[0031] The guide post 12 is sleeved on the inner positions of both ends of the bracket body 11, and the dust cover 13 is sleeved on the outer surface of the guide post 12;

[0032] The guide post 12 is used to guide the movement of the automotive brake caliper, and the dust boot 13 is used to prevent dust and water from entering the guide post 12 inside the automotive brake caliper;

[0033] The second fixed shaft 27 is fixedly connected to both ends of the fixed block 22, and the connecting rod 26 is located on both sides of the connecting plate 24;

[0034] The connecting rod 26 and the connecting plate 24 can rotate along the first fixed shaft 23 and the second fixed shaft 27 respectively;

[0035] The retaining ring 28 has a T-shaped structure. The inner surface of the outer end of the retaining ring 28 is in contact with the outer surface of the guide post 12, and the outer end of the retaining ring 28 is located outside the dust boot 13;

[0036] When the guide post 12 moves, the retaining ring 28 can be driven by the fixed ring 21 to move on the outer surface of the guide post 12;

[0037] Working principle: When the guide post 12 moves inside the bracket body 11, the guide post 12 drives the fixed ring 21 to move outward. The fixed ring 21 drives the fixed block 22 to move. The movement of the fixed block 22 drives the second fixed shaft 27 to move. The second fixed shaft 27 drives the connecting rod 26 to rotate inward. The connecting rod 26 drives the connecting plate 24 to rotate inward through the support shaft 25, so that the connecting plate 24 and the connecting rod 26 are located on both sides of the guide post 12. And the fixed ring 21 drives the retaining ring 28 to move outward. At this time, the connecting plate 24 and the connecting rod 26 can partially block the outside of the guide post 12, reducing the contact between the guide post 12 and external dust and rainwater, etc.;

[0038] When the guide post 12 resets, the guide post 12 drives the fixed ring 21 to move in the reverse direction, and drives the connecting rod 26 to rotate outward through the fixed block 22 and the second fixed shaft 27. The connecting rod 26 drives the connecting plate 24 to rotate outward through the support shaft 25, so that the connecting rod 26 rotates to the outer end position of the connecting plate 24. And the movement of the fixed ring 21 drives the retaining ring 28 to move inward. The movement of the retaining ring 28 scrapes the outer surface of the guide post 12, so that impurities such as dust and rainwater attached to the outer surface of the guide post 12 are scraped off, and the contact between the dust and rainwater and the dust boot 13 can be reduced.

[0039] Please refer to Figure 4 As shown in the figure, on the basis of the above embodiment, this embodiment further includes:

[0040] A fixing assembly, which includes a telescopic spring 31, a fixing piece 32 and a fixing groove 33;

[0041] The telescopic spring 31 is fixedly connected to the inner circumference of the fixed ring 21. The fixing piece 32 is fixedly connected to the outer end of the telescopic spring 31. The fixing groove 33 is opened on the outer surface of one end of the dust boot 13;

[0043] The fixing piece 32 is in an arc-shaped structure, and the fixing groove 33 is formed relative to the fixing piece 32;

[0044] When the fixing piece 32 is placed inside the fixing groove 33, the fixing piece 32 is located around the outer surface of the dust cover 13;

[0045] Working principle: When it is necessary to fix and seal the dust cover 13, an outward force is applied to the fixing piece 32 to move the fixing piece 32 outward. The outward movement of the fixing piece 32 drives the telescopic spring 31 to be compressed. The telescopic spring 31 generates an elastic force when compressed. At this time, the fixing ring 21 is sleeved on one end of the dust cover 13 and the positions of the fixing piece 32 and the fixing groove 33 are made to correspond. Then, the force applied to the fixing piece 32 is stopped. Under the elastic force of the telescopic spring 31, the fixing piece 32 moves inward into the fixing groove 33, so that the fixing piece 32 enters the fixing groove 33, and the telescopic spring 31 is still in a compressed state and applies an inward force to the fixing piece 32, so that the fixing piece 32 presses the dust cover 13 inward, thereby keeping the inner surface of the dust cover 13 in close contact with the outer surface of the guide post 12. While fixing the dust cover 13 on the guide post 12, the outer surface of the guide post 12 is sealed.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
