The convex block 111 is slidably arranged in the sliding groove 211 and contacted tightly with each other. A top surface of the accommodating portion 21 may be contacted with a top surface of the assembly portion 11 so that the top surface of the accommodating portion 21 may be not protruded from the top surface of the assembly portion 11 (shown as in FIGS. 1 and 3).

[0032] Please refer to FIGS. 2 and 4. The dovetail-shaped convex block 111 is extended from top to bottom and the dovetail-shaped sliding groove 211 is extended from top to bottom. The dovetail-shaped sliding groove 211 is slid from a wider end of the convex block 111 to a narrower end of the convex block 111 which is opposite to the wiser end of the convex block 111 so that the dovetail-shaped convex block 111 is slid in the dovetail-shaped sliding groove 211. The sliding groove 211 is penetrated from top to bottom. Besides the process in the processing factory may be more easily, the users may exactly know how to assemble while replacing.

[0033] Please refer to FIGS. 1 and 2. A plurality of heat dissipation posts 22 are extended outwardly from the heat dissipation pad 2. Each of the heat dissipation posts 22 is a long elliptical cylinder. A left side and a right side of each heat dissipation posts 22 is symmetric for providing the guidance of the air to flow downwardly and toward a brake caliper 4 to reduce the temperature of the brake caliper 4 (shown as in FIG. 6). Each of the heat dissipation posts 22 is arranged opposite to the accommodating portion 21. Please also refer to FIGS. 2 to 4. A brake shoe 12 is further arranged at the brake pad 1 and located below one side of the brake pad 1 which is opposite to the assembly portion 11. A middle section of the brake pad 1 is arranged an intersecting hole 13. And further after a pivoting member 3 is passing through the intersecting hole 13, the brake pad 1 is assembled to the brake caliper 4 and located at two sides of a brake disc 5 (shown as in FIG. 5).

[0034] According to above mentioned structure, please refer to FIG. 5. While being assembled to two sides of the brake disc 5, the pivoting member 3 is passing through the intersecting hole 13 of the brake pad 1 to fasten on the brake caliper 4 so that the brake shoe 12 is toward the brake disc 5. While braking, the brake shoe 12 may be rubbed against the brake disc 5 to slow down. And simultaneously, the heat which is generated from the brake shoe 12 may be quickly dissipated by each heat dissipation post 22 of the heat dissipation pad 2 to keep good brake performance.

[0035] Please refer to FIG. 2. A center of the assembly portion 11 has a screw hole 112. A center of the heat dissipation pad 2 has a through hole 212. A screw bolt 6 is passing through the through hole 212 of the accommodating portion 21 and then screwed in the screw hole 112 of the assembly portion 11 so that he heat dissipation pad 2 may be locked and fastened to the brake pad 1 tightly (shown as in FIG. 1).

[0036] Please refer to FIG. 7. The heat dissipation structure of the present invention may further comprise an elastic member 7 and an abutting member 8. The assembly portion 11 has an accommodating groove 113 and the accommodating portion 21 has a clamping hole 213. The elastic member 7 and the abutting member 8 are arranged in the accommodating groove 113. Two ends of the elastic member 7 are respectively elastically abut against the accommodating groove 113 and the abutting member 8. One end of the abutting member 8 which is opposite to the elastic member 7 has a convex post 81 and the convex post 81 is clamped in the clamping hole 213. When the heat dissipation pad 2 is slid downwardly to assemble to the brake pad 1, the dovetail-shaped sliding groove 211 of the accommodating portion 21 is slid to assemble to the dovetail-shaped convex block 111 of the assembly portion 11. A bottom surface of the heat dissipation pad 2 may be abut against the convex post 81 of the abutting member 8 which is arranged in the accommodating groove 113 so that the abutting member 7 is abut against the elastic member 7 toward the accommodating groove 113. When the heat dissipation pad 2 is slid to be positioned, the abutting member 8 is elastically abut against the elastic member 7 to make the convex post 81 be clamped in the clamping hole 213 so that the heat dissipation pad 2 may be firmly assembled to the brake pad 1. When disassembling the heat dissipation pad 2, the convex post 81 is pressed to separate from the clamping hole 213 and then the heat dissipation pad 2 is slid upwardly to finish disassembling.

[0037] Please refer to FIG. 8. Besides the above mentioned assembly of the convex block 111 and the sliding groove 211, another assembly is that the sliding groove 211 is slid from a right side of the convex block 111 so that the convex block 111 may be slid into the sliding groove 211. Besides the process in the processing factory may be more easily, the users may exactly know how to assemble and what the direction is while replacing.

[0038] When the brake shoe 12 is rubbed to be damaged and needs to replace, the screw bolt 6 may be screwed out or the convex post 81 may be pressed to separate the heat dissipation pad 2 from the brake pad 1. The heat dissipation pad 2 which is not damaged may be reused. That is, the heat dissipation pad 2 may keep using. It means that the heat dissipation pad 2 which is not damaged may be replaced to assemble to an assembly portion 11 of another brake pad 1 to reuse for providing the effect of heat dissipation.
