[0007] A waterproof automobile door rubbing strip assembly, comprising a rubbing strip body, the rubbing strip body comprising a wear-resistant layer, a waterproof layer and a filling layer, the wear-resistant layer being arranged on the outer surface of the waterproof layer, the waterproof layer having a cavity inside, the cavity having a filling layer inside, one side of the rubbing strip body being provided with a mounting slot, and the mounting slot being fixedly connected with a U-shaped adhesive inside.
[0008] Preferably, the material of the wear-resistant layer is neoprene.
[0009] Preferably, the material of the waterproof layer is silicone rubber.
[0010] Preferably, the material of the filling layer is butyl rubber.
[0011] Preferably, one side of the rubbing strip body is provided with an arc-shaped drainage groove.
[0012] Preferably, one side of the anti-chafing strip body is fixedly connected with a plurality of wear-resistant protrusions, and each wear-resistant protrusion is arranged on the two sides of the arc-shaped drainage groove.
[0013] Preferably, an arc-shaped groove is arranged on the side of the anti-chafing strip body away from the mounting clamping groove, and the two ends of the arc-shaped groove are provided with chamfers.
[0014] In the above technical solution, the technical effects and advantages of the utility model are provided.
[0015] 1. The utility model discloses a wear-resistant layer, a waterproof layer and a filling layer, realize the wear resistance, waterproof and buffering function of anti-chafing strip, wherein the wear-resistant layer adopts neoprene material, has good anti-aging and wear resistance, can effectively resist ultraviolet and daily friction, prolongs the service life of anti-chafing strip, reduces the economic cost and time cost caused by frequent replacement of anti-chafing strip.
[0016] 2. The utility model discloses that the arc-shaped drainage groove is arranged on one side of the anti-chafing strip body, can guide and discharge the rainwater accumulated on the anti-chafing strip in time, avoids that the rainwater is infiltrated into the car after accumulating on the anti-chafing strip.
