Description

Tool convenient for inflating vehicle by external air source

Technical Field

The utility model relates to an aerify supplementary this instrument technical field, concretely relates to instrument convenient to external air supply of vehicle is aerifyd.

Background

The vehicle is a generic term of "vehicle" and a unit of vehicle ". The vehicle refers to a vehicle that rotates on land with wheels; the vehicles are derived from the ancient metering method of the vehicles. The vehicles at that time are generally two wheels, so that the vehicles are called one by two and are written as vehicles later. Therefore, the vehicle is not powered by itself, and is called a carriage drawn by a horse and a rickshaw pulled or pushed by a person. With the development of science and technology, automobiles towed by a steam engine and the like are available. At this time, the concept of the vehicle has changed quietly, and becomes a general name of all vehicles.

The vehicle has a complex structure and comprises a plurality of systems, specifically a comfort system, a power system, a transmission system, a safety protection system, a brake system, an anti-theft system, an auxiliary driving system and the like; these systems are controlled mainly by the electric circuit, hydraulic circuit, pneumatic circuit and mechanical structure of the whole vehicle.

The air pressure loop of the vehicle is connected with an air storage cylinder and a prefabricated inflating pump and used for providing air pressure for braking, a door pipeline and an air bag pipeline of the vehicle. Wherein, an external air source joint is also connected in the air pressure loop. When the prefabricated inflating pump cannot work, a plurality of mechanisms in the vehicle cannot work normally, tires are locked and cannot be pulled to a maintenance point for maintenance, therefore, an external air source needs to be connected to an external air source connector, an air pressure loop is inflated, and the vehicle can move normally.

The current method is as follows: the rear compartment of the vehicle is opened, the joint between the prefabricated inflating pump and the air storage tank is opened, the air pipe is connected to the joint of the air storage tank, the other end of the air pipe is connected with an external inflating pump carried on a trailer, and the air is supplied to the air pressure loop through the external inflating pump.

By adopting the method for inflating, on one hand, the box cover and the joint are troublesome to disassemble and unsafe on the road, and meanwhile, when the joint of the prefabricated inflating pump is not connected, the opening of the pipe is often omitted for sealing, so that sundries fall into the pipeline, and air leakage or more serious consequences are caused; on the other hand, the trailer can inflate the faulty vehicle only by carrying an external inflation pump, which causes inconvenience.

SUMMERY OF THE UTILITY MODEL

For overcoming prior art's defect, the utility model aims to provide a be convenient for aerify instrument of external air supply of vehicle, the air supply that can be directly on normal vehicle or the trailer is aerifyd for trouble vehicle.
