Brake caliper friction plate active return mechanism

The invention discloses an active return mechanism for a friction plate of a brake caliper. The active return mechanism comprises a return structure assembly, the friction plate and a brake caliper bracket, the return structure assembly is arranged between the friction plate and the brake caliper bracket; the return structure assembly comprises two locking rubber blocks and a return keeping sliding block, the return keeping sliding block comprises a bottom plate and two side plates oppositely arranged at the two ends of the bottom plate, and an elastic piece structure is arranged on the bottom plate; the brake caliper support is provided with a sliding groove allowing the return keeping sliding block to move in the first direction, and the first direction is the direction in which the friction plate moves towards the brake disc under the hydraulic effect. The two side walls of the sliding groove are provided with clamping grooves for installation of the locking rubber blocks, and the side plates make contact
