description The utility model discloses a vehicle stopping protecting and accelerating device. The device comprises a potentiometer, a pinion, a big gear, a switch and an extension spring. The big gear is smaller than or equal to one-fourth of a common gear, the pinion is connected with the potentiometer, and meshed with the big gear, the big gear is cut to form an inwards-concave step face, and the inwards-concave step face abuts against the switch so that the switch can be switched on or off when the big gear rotates. The big gear is connected with a foot rest lever, and automatic resetting is achieved through the extension spring after the foot rest lever is released. The inwards-concave step face of the big gear abuts against the switch, the micro switch is switched on or off when the big gear rotates, meanwhile the pinion is driven to rotate and drives the potentiometer to rotate to achieve accelerating or decelerating, and therefore the functions of vehicle stopping protecting and accelerating are achieved. The vehicle stopping protecting and accelerating device is simple in structure and working principle, safe, reliable and suitable for different structural features.
