Abstract

The invention discloses an automatic fuel tank cover, which comprises an oil inlet hole, a fuel tank cover, a main shaft, a motor and a fuel tank. Connect with the motor. After the oil is full, the floating plate rises, and the first magnet attracts the second magnet to move to the right, thereby pulling the lock tongue away from the oil gun. At this time, the oil gun can be pulled out. After the oil gun is pulled out, the third slider will move due to gravity Down, the second spring pushes the second slider up to make the rack go down, pull back the lock tongue and lock block, the first spring pushes the first slider to move to the right, then the driver starts the motor, drives the main shaft to rotate, and the main shaft drives The first gear rotates. Since the teeth of the first gear and the second gear overlap at this time, the first gear and the main shaft cannot fall due to gravity. After rotating for a period of time, the first gear and the second gear mesh again, and the main shaft descends at this time. Drive the fuel tank cap closed.

Description

technical field [0001] The invention relates to a fuel tank cap, and in particular provides an automatic fuel tank cap. Background technique [0002] The fuel tank cap refers to the box on the car for storing gasoline. The shape is square, made of stainless steel, and the airtightness is very good. There is only a small circular entrance, which is only as big as the cap of the bottle, which is convenient for storage. It is usually placed at the rear of the car. The fuel tank cap of the car is a device used to cover the opening of the fuel tank. When in use, open the fuel tank cap of the car, then insert the tip of the refueling gun to refuel, and close the fuel tank cap after refueling [0003] But some car owners forget to close the fuel tank cap after refueling, causing the gasoline in the fuel tank to overflow or even cause more serious problems. Therefore, it is necessary to design a fuel tank cap for automatic opening and closing. Contents of the invention [0004...
