Brake-by-wire structure based on vehicle and working method of brake-by-wire structure

The invention relates to the technical field of brakes, and discloses a brake-by-wire structure based on a vehicle and a working method thereof.The brake-by-wire structure comprises a motor device, a fixing shell is fixedly connected to the bottom of the motor device, a lifting plate is movably connected to the outer side of the fixing shell, and a moving block is movably connected to the interior of the lifting plate; a heat dissipation device is fixedly connected to the interior of the fixing shell, a brake disc is placed on the inner side of the fixing shell, and a wheel shaft is fixedly connected to one side of the brake disc. By arranging the movable block, the situation that the vehicle is out of control due to sudden pressure when the vehicle is braked is avoided, the connecting board eraser block is arranged on the movable block, impurities on the brake disc can be cleared away, the brake disc becomes cleaner, and the situation that the brake effect is affected due to the fact that the impurities are
