Description

Technical Field

[0001] The utility model relates to a safety protection type control board for an automobile air pump, belonging to the technical field of air pump control boards. Background Technique

[0002] Accidents caused by uneven tire pressure occur frequently. It can be seen that keeping the tire pressure during driving at any time cannot be underestimated. During high-speed driving, tire blowouts mainly occur due to too low or too high tire pressure. With the continuous increase of domestic cars and the shortage of petroleum resources and the continuous rise of oil prices, reducing fuel consumption has become the primary problem for each car owner. The tire pressure is very particular. Too low or too high pressure will increase fuel consumption and reduce the service life of the tires. Therefore, it is necessary to have an air pump with "high precision and fast inflation" during driving. An automobile tire inflator, also called an air charger, an air compressor, or a vehicle-mounted inflator, works by the operation of an internal motor. When pumping air, the valve of the communicating vessel is pushed open by the air pressure of the atmosphere, and the gas enters the air cylinder. When inflating the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire. It can be said that the principle of atmospheric pressure is used to inflate cars, balls, and rubber boats.

[0003] In the internal circuit control board structure of the existing inflator, there is no limiting device on the side of the circuit board, which will cause the circuit board to tilt or rotate on both sides when moving towards the inside of the outer casing during installation, so that the mounting holes on the circuit board cannot correspond to the support columns, and manual adjustment is still required, affecting the installation efficiency and needing to be improved.
