Problems solved by technology
[0002] After the electric vehicle has been used for a period of time, the internal gas volume of the wheels will gradually decrease due to air leakage and other reasons; now, manual inflators and electrical inflators are generally used. Manual inflators are small in size and easy to carry, but they are laborious to use and inflated. The piston rod of the barrel moves up and down once, and the amount of inflation is very small. It takes a long time to pull the piston rod several times to fill the air once, and it takes a long time to fill the wheels; It is not easy to carry, and it cannot be inflated in time when the wheels are out of gas

The invention relates to a gas-filling unit of an electric vehicle. The gas-filling unit comprises a gas-filling shell and a gas-filling body arranged in the shell, wherein the gas-filling body comprises a motor; the motor is connected with a gas pump through a transmission mechanism; the output end of the gas pump is connected with a gas-filling nozzle through a gas-filling pipe; and a switch for controlling the opening and closing of the motor is arranged outside the gas-filling shell. According to the invention, the gas-filling unit is integrated in the small-size gas-filling shell so that the gas-filling unit disclosed by the invention is convenient for carrying; an electric gas-filling pump and the transmission mechanism are arranged, thus manual gas filling is not needed, and the motor is started by the switch so as to achieve the automatic gas filling of a wheel; and a socket is arranged in the gas-filling unit, thus the motor can be charged according to the requirement.
Description
technical field [0001] The invention relates to an electric vehicle inflator and belongs to the technical field of inflators. Background technique [0002] After the electric vehicle has been used for a period of time, the internal gas volume of the wheels will gradually decrease due to air leakage and other reasons; now, manual inflators and electrical inflators are generally used. Manual inflators are small in size and easy to carry, but they are laborious to use and inflated. The piston rod of the barrel moves up and down once, and the amount of inflation is very small. It takes a long time to pull the piston rod several times to fill the air once. The electric inflation device is simple, fast and labor-saving to use, but its volume and weight make it It is not easy to carry, and it cannot be inflated in time when the wheels are out of gas. Contents of the invention [0003] The purpose of the present invention is to provide an electric vehicle inflator that is conveni...
