The invention provides a moving-type automatic inflating device for a vehicle, which belongs to the technical field of vehicles. The moving type automatic inflating device comprises hubs, bearings and wheel axles and is characterized in that a micro inflating pump, a storage battery and a gas distributor are arranged; one end of the micro inflating pump is connected with the storage battery; the other end of the micro inflating pump is connected with the gas distributor through a plastic hose; the wheel axles are a semi-hollow wheel axles which have gas guide holes; a gas inlet of the gas guide hole is formed in the end part of one end of each semi-hollow wheel axle and is connected with a gas conveying nozzle in the gas distributor through a plastic hose; a gas outlet is formed in the middle axle wall of each semi-hollow wheel axle and is communicated with an annular cavity; a connecting gas nozzle is formed in the wall of each hub axle hole; one end of each connecting gas nozzle is communicated with the annular cavity; and the other end of each connecting gas nozzle is connected with a tire gas nozzle through a plastic hose. According to the invention, tires are automatically inflated; in case that an inflating pressure is larger than air leaking pressure, a user can ride the vehicle normally; and the tires can be inflated at any time; therefore, the moving-type automatic inflating device is simple in operation and exerts good inflating effect, and the service life of the tires can be effectively prolonged.
