The invention provides a safety protection device for an automobile accelerator. The safety protection device comprises an accelerator pedal, an accelerator sensor, an accelerator linkage switch, a vacuum booster and a brake master cylinder push rod. The accelerator sensor and the accelerator linkage switch are rotationally buckled. The vacuum booster comprises a valve block shell, a vacuum booster magnetic attracting coil contained in the valve block shell, and a vacuum booster magnetic attracting armature. The brake master cylinder push rod and the valve block shell are connected. When the treading pressure borne by the accelerator pedal reaches the maximum pressure threshold value, the accelerator sensor stops rotating, the accelerator linkage switch still rotates, and therefore the accelerator sensor and the accelerator linkage switch are disengaged; in addition, the accelerator linkage switch is connected with a circuit and triggers the vacuum booster magnetic attracting coil to generate magnetic force and attract the vacuum booster magnetic attracting armature to move, and therefore the valve block shell and the brake master cylinder push rod are driven to move together to make an automobile brake.
