Abstract
The utility model relates to an automatic inflator pump which can automatically inflate an air-leaking tire during a driving process of a vehicle so as to ensure the continuous driving of the vehicle under a specific condition. A pump body is connected with a hub of a wheel; an inflating cylinder and a brake cylinder which are vertically communicated with each other are arranged in the pump body; pistons and springs are arranged on both of the inflating cylinder and the brake cylinder; the inflating cylinder is communicated with the tire through a check valve and an air pipe; the brake cylinder is communicated with the air pipe through an air-guide pipe; a driving ring is connected with a steering knuckle; through holes connected with the inflating cylinder are formed on the hub and a brake plate; and a transmission rod is arranged in the through holes. When the tire leaks air during the driving process, the transmission rod and the inflating piston can reciprocate under the co-action of the driving ring and the springs, so as to inflate the tire. When the air pressure in the tire and the air pipe reaches a rated value, the piston in the brake cylinder enters into the inflating cylinder under the driving of the air pressure, so as to stop the reciprocation of the piston in the inflating cylinder.
