[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0018] As shown in Figure 1-3, a corrosion-resistant triangular swing arm includes a triangular arm 10, and a connecting ring 11 is fixed at the three corners of the triangular arm 10. A dust removal assembly is arranged in the connecting ring 11. The dust removal assembly can reduce the residence time of debris such as dust and water on the triangular arm 10. The dust removal assembly includes a friction wheel 15 in the connecting ring 11, and also includes a one-way wheel outer ring 16 and a one-way wheel inner ring 17, wherein the friction wheel 15 is rotatably connected in the connecting ring 11, and the friction wheel 15 abuts against the outer peripheral side of the one-way wheel inner ring 17. The friction wheel 15 rotates in the connecting ring 11, and part of the friction wheel 15 is located outside the connecting ring 11. A rotating shaft is fixedly installed at the center of the one-way wheel outer ring 16, and a fan 18 is installed at one end of the rotating shaft, and the other end is rotatably connected to the inner wall of the connecting ring 11.

[0019] An inner cavity 12 is opened in the connecting ring 11, and the inner cavity 12 is close to the triangular arm 10. The inner cavity 12 is arranged in an arc shape. A plurality of air outlets 13 are opened on the outer peripheral side of the connecting ring 11 close to the triangular arm 10, and the air outlets 13 are connected with the inner cavity 12. A plurality of air inlets 14 are also opened on the end faces on both sides of the connecting ring 11, and the air inlets 14 are connected with the inner cavity 12. The air outlet 13 is inclined so as to face the end face of the triangular arm 10.

[0020] At least three dust removal components are provided, and the one-way wheel outer ring 16 and the one-way wheel inner ring 17 in two adjacent dust removal components rotate in opposite directions, that is, when the rubber sleeve drives the friction wheel 15 to rotate, the dust removal component can blow air outward continuously without stopping, and the rubber sleeve can avoid driving the fan 18 to rotate back and forth through the friction wheel 15, so that the air outlet 13 becomes the air intake port.

[0021] During use, after the triangular swing arm is installed, during use, the rubber sleeve in the connecting ring 11 will produce reciprocating relative rotation with the connecting ring 11 due to the ups and downs of the vehicle or at least its movement. At this time, the rubber sleeve can drive the one-way wheel inner ring 17 to rotate through the friction wheel 15, and the rotation of the one-way wheel inner ring 17 can drive part of the rotating shaft to rotate, thereby rotating the fan 18. At this time, the rotation of the fan 18 can inhale air from the air inlet 14 and blow it out from the air outlet 13, thereby accelerating the air flow at the connection between the connecting ring 11 and the triangular arm 10. On the one hand, it can blow off the dust on it, and on the other hand, when there is sewage on it, it can accelerate the loss of water flow, thereby reducing the time that the sewage adheres to the triangular swing arm, thereby greatly reducing the degree of corrosion, and achieving a corrosion-resistant effect.

[0022] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
