[0024] As Figures 1-4 shown, a snap-in mounting mechanism for an automotive brake pad includes: a mounting negative film 1 with an arc-shaped outer wall, an arc brake pad 2 detachably connected to the mounting negative film 1 through a plurality of sets of connecting mechanisms, and a brake lining 3 assembled on the outer side wall of the arc brake pad 2. The mounting negative film 1 and the arc brake pad 2 form a brake shoe through the connecting mechanism.

[0025] When replacement is needed, the connecting mechanism is removed to disassemble the arc brake pad 2 and the arc brake pad 2, and the whole of the arc brake pad 2 and the brake lining 3 is replaced. The whole of the new brake lining 3 and the arc brake pad 2 is assembled on the mounting negative film 1 through the connecting mechanism without removing the mounting negative film 1, which reduces the replacement difficulty and improves the replacement efficiency.

[0026] A plurality of mounting parts 4 which are fixedly arranged on the inner side wall of the arc brake pad 2 and can be in close contact with the mounting negative film 1 and correspond to a plurality of sets of connecting mechanisms are provided, and a mounting through hole is penetrated through each mounting part 4;

The connecting mechanism includes a mounting bolt 6 that can pass through the mounting through hole and the special-shaped through groove 5 and a special-shaped nut 7 that can pass through the special-shaped through groove 5 and can abut against the side of the mounting negative film 1 away from the mounting part 4.

[0028] When replacement is needed, loosen and remove the mounting bolt 6, remove the old arc brake pad 2 and the brake lining 3, fit the mounting part 4 on the new arc brake pad 2 to the mounting negative film 1, and align the mounting through hole with the special-shaped through groove 5, then the mounting bolt 6 can pass through the mounting through hole and the special-shaped through groove 5 and be connected with the special-shaped nut 7.

[0029] A pair of coaxially arranged arc-shaped ridges 8 are protrudingly provided on the inner wall of the arc-shaped brake pad 2, and the pair of arc-shaped ridges 8 are spaced along the axial direction of the arc-shaped brake pad 2 to form an arc-shaped card slot for inserting the edge of the mounting negative film 1.

[0030] During assembly, the edge of the mounting chassis is inserted into the arc-shaped card slot, and the arc-shaped card slot can improve the connection firmness between the arc-shaped brake pad 2 and the mounting negative film 1.

[0031] A positioning portion 9 for clamping the special-shaped nut 7 is provided on the side of the mounting negative film 1 away from the mounting portion 4 and beside the corresponding special-shaped through slot 5.
