[0006] Preferably, the driving device is a driving spring, one end of the driving spring abuts against the side wall of the scraping plate, and the other end of the driving spring abuts against the side wall of the extension plate.

[0007] Preferably, a stabilizing rod is arranged on the side of the scraping plate close to the extension plate, a stabilizing hole for the other end of the stabilizing rod to pass through is formed in the side wall of the extension plate, and the driving spring is sleeved on the periphery of the stabilizing rod.

[0008] Preferably, a jacking cylinder is arranged between the scraping plate and the brake body, and the output end of the jacking cylinder abuts against the side wall of the scraping plate.

[0009] Preferably, a roller is rotatably connected to the output end of the jacking cylinder, and the roller rolls and slides on the side wall of the scraping plate.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When encountering rainy weather, the output end of the ejecting cylinder moves back, and at the same time, the driving spring ejects the scraper, causing the scraper to rotate, making the outer end of the scraper approach the brake disc. Then, the rubber strip scrapes the water on the side wall of the brake disc, thereby maintaining the dryness between the rubber strip and the brake disc and maintaining the braking efficiency between the brake disc and the brake pads.

[0014] 2. During the rotation of the scraper, one end of the stabilizing rod on the scraper passes through the stabilizing hole, and the driving spring is sleeved on the periphery of the stabilizing rod, so that the driving spring is always located between the scraper and the extension plate, improving the stability of the driving spring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the accompanying drawings.

[0019] The embodiment of the present application discloses an automotive brake pad.

[0020] Referring to Figure 1 and Figure 2 , it includes a brake body 1. The front side of the brake body 1 is the working surface, the rear side of the brake body 1 is the mounting surface, extension plates 2 are integrally provided at both ends of the brake body 1 respectively, the side walls of the extension plates 2 are flush with the mounting surface of the brake body 1, and scrapers 3 are rotatably connected to both ends of the brake body 1 respectively.

[0021] A rubber strip 4 is placed at the outer end of the scraping plate 3. A trapezoidal block 5 is integrally provided on one side of the rubber strip 4. A trapezoidal groove 6 is formed at the outer end of the scraping plate 3. The trapezoidal block 5 is inserted and fixed in the trapezoidal groove 6. The side of the rubber strip 4 away from the scraping plate 3 is flat. A limiting block 7 is integrally provided on the side of the trapezoidal block 5 close to the scraping plate 3. The limiting block 7 is hemispherical. The scraping plate 3 is provided with a limiting groove 8 at the bottom of the trapezoidal groove 6 for the limiting block 7 to be snap-fitted and fixed. When the rubber strip 4 needs to be replaced, first pull out the trapezoidal block 5 from the trapezoidal groove 6, and then insert the trapezoidal block 5 of the new rubber strip 4 into the trapezoidal groove 6 until the limiting block 7 is snap-fitted and fixed in the limiting groove 8, so as to install the new rubber strip 4 at the outer end of the scraping plate 3.

[0022] There is a driving device 9 between the scraping plate 3 and the extension plate 2. The driving device 9 is a driving spring 10. A stabilizing rod 11 is welded and fixed on the side of the scraping plate 3 close to the extension plate 2. The stabilizing rod 11 is arc-shaped. A stabilizing hole 12 for the stabilizing rod 11 to pass through is formed in the side wall of the extension plate 2. The driving spring 10 is sleeved on the periphery of the stabilizing rod 11. One end of the driving spring 10 abuts against the side wall of the extension plate 2, and the other end abuts against the side wall of the scraping plate 3. During the rotation of the scraping plate 3, one end of the stabilizing rod 11 on the scraping plate 3 passes through the stabilizing hole 12, and the driving spring 10 is sleeved on the periphery of the stabilizing rod 11, so that the driving spring 10 is always located between the scraping plate 3 and the extension plate 2.

[0023] Ejecting cylinders 13 are respectively fixed at both ends of the brake body 1 through bolts. The output end of the ejecting cylinder 13 is rotatably connected with a roller 14. The periphery of the roller 14 rolls and slides on the side wall of the scraping plate 3. The output end of the ejecting cylinder 13 retracts, and at the same time, the driving spring 10 ejects the scraping plate 3, so that the scraping plate 3 rotates, making the outer end of the scraping plate 3 approach the brake disc. Then, the rubber strip 4 scrapes the water on the side wall of the brake disc, so as to keep the dryness between the rubber strip 4 and the brake disc.

[0024] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
