Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, a brake steel back of an automobile brake pad includes a steel back body 2, a connecting plate 11 slidably arranged on the steel back body 2, and a friction block 12 attached to the connecting plate 11, the connecting plate 11 and the friction block 12 are each provided with a plurality of corresponding heat dissipation holes 10, the steel back body 2 is provided with a plurality of mounting holes 20, and a blower mechanism 5 is provided in each of the mounting holes 20, the blower mechanism 5 achieves the effect of cooling the friction block 12 by blowing air through the heat dissipation holes 10, and a dustproof net 6 is provided in each of the mounting holes 20, thereby preventing dust from entering the mounting holes 20.

[0025] The hair dryer mechanism 5 includes a sleeve 52, a movable rod 51 and a fan blade 53 arranged outside the sleeve 52. The number of the fan blades 53 in the present application is five, and in addition to the number of five, it can also be any number of fan blades 53. The sleeve 52 is rotatably installed in the installation hole 20, the movable rod 51 is fixedly installed on the connecting plate 11, and the dustproof net 6 is slidably matched with the movable rod 51. The movable rod 51 is movably arranged in the sleeve 52, and a spiral groove 520 is provided in the sleeve 52. The movable rod 51 is provided with a sliding groove that slides with the spiral groove 520. A fixing block 54, wherein a cover body 541 is fixedly connected to the end of the fixing block 54, and the cover body 541 and the fixing block 54 are snap-fitted together, and an installation cavity 543 is formed between the cover body 541 and the fixing block 54, and a ball 542 is installed in the installation cavity 543, and the ball 542 cooperates with the spiral groove 520 roller. In the present application, a plurality of installation cavities 543 are provided between the cover body 541 and the fixing block 54, and each of the installation cavities 543 is provided with a ball 542, so that the fixing block 54 can move more smoothly in the spiral cavity.

[0026] A damper 3 and a spring 4 are disposed between the connecting plate 11 and the steel back body 2. The spring 4 is disposed on the periphery of the damper 3, so that the spring 4 and the damper 3 can play a buffering role during braking. In addition, by installing the spring 4 on the periphery of the damper 3, the number of holes opened on the steel back body 2 can be reduced, thereby improving the strength of the steel back body 2.

[0027] The steel back body 2 includes a mounting plate 22 and a fixed plate 21, and a reinforcing rib 23 is provided between the fixed plate 21 and the mounting plate 22.
