DETAILED DESCRIPTION OF THE INVENTION

[0024] Referring to the drawings and initially to FIGS. 1 and 2, a brake pad in accordance with the present invention comprises a main plate 10 and a brake lining 20 secured on one face of the main plate 10. A heat dissipation structure 30 is formed on one side of the main plate 10 opposite to the brake lining 20, wherein the heat dissipation structure 30 guides a backward airflow toward the main plate 10 for promoting the heat dissipation effect of the main plate 10 and the lining 20 during braking process or finishing braking process.

[0025] The main plate 10 has a first face and a second face, wherein the brake lining 20 is secured on the first face of the main plate 10. The heat dissipation structure 30 includes multiple first heat dissipation fins 31, multiple second heat dissipation fins 32 and a guard 33 respectively extending from one side of the main plate 10 opposite to the brake lining 20. The guard 33 surrounds the multiple first heat dissipation fins 31 and the multiple second heat dissipation fins 32 for preventing the multiple first heat dissipation fins 31 and the multiple second heat dissipation fins 32 from being deformed and reducing the original brake effect due to an improper buffet. The multiple first heat dissipation fins 31 and the multiple second heat dissipation fins 32 are reversally and alternately arranged relative to each other. In the preferred embodiment of the present invention, the multiple first heat dissipation fins 31, the multiple second heat dissipation fins 32 and the guard 33 are integrally formed with the main plate 10.

[0026] With reference to FIG. 3, each of the second heat dissipation fins 32 is bent toward the second face of the main plate 10. The multiple first heat dissipation fins 31 and the main plate 10 are arranged on a same plane, and the multiple second heat dissipation fins 32 and the guard 33 are arranged on a same plane.

[0027] With reference to FIG. 4 that shows a second embodiment of the brake pad in accordance with the present invention, in this embodiment, the distal side of the guard 33 is bent and parallel to the main plate 10.

[0028] With reference to FIG. 5 that shows a third embodiment of the brake pad in accordance with the present invention, in this embodiment, the multiple first heat dissipation fins 31 and the main plate 10 are arranged on a same plane, and the guard 33 is arranged between the multiple first heat dissipation fins 31 and the multiple second heat dissipation fins 32.

[0029] With reference to FIG. 6, each first heat dissipation fin 31 and each second heat dissipation fin 32 have a rear end relative to a moving direction. Each rear end of the multiple first heat dissipation fins 31 and multiple second heat dissipation fins 32 are inwardly bent toward main plate 10 for enlarged windward face of the multiple first heat dissipation fins 31 and multiple second heat dissipation fins 32. In addition, the bent multiple first heat dissipation fins 31 and multiple second heat dissipation fins 32 guide the backward airflow W to the main plate 10 and the brake lining 20 for promoting the heat dissipation effect of the brake pad in accordance with the present invention.

[0030] With reference to FIG. 7 that shows a fourth embodiment of the brake pad in accordance with the present invention, the guard 33 in the third embodiment has a continually wave-shaped cross-section.

[0031] With reference to FIG. 8 that shows a fifth embodiment of the brake pad in accordance with the present invention, a free end of each of the multiple second heat dissipation fins 32 in the third embodiment is bent and parallel to the main plate 10.

[0032] With reference to FIG. 9 that shows a sixth embodiment of the brake pad in accordance with the present invention, the guard 33 in the fifth embodiment has a continually wave-shaped cross-section.

[0033] As described above, each heat dissipation fin 31/32 is bent for enlarging a windward face thereof and guiding the backward airflow toward the main plate 10 and the brake lining 20. Consequently, the heat dissipation effect of the main plate 10 and the brake lining 20 is greatly promoted relative to the conventional brake pad in accordance with the prior art.

[0034] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
