Description

Technical Field

[0001] The utility model belongs to the technical field of air pumps, and specifically relates to a linear vehicle-mounted air pump movement. Background Art

[0002] A car tire air pump, also known as an inflator, air pump, or car air pump, is specifically designed to inflate car tires. It operates by running an internal motor, using atmospheric pressure to draw air into and pressurize the tire. The design of a car tire air pump allows drivers to quickly inflate tires without specialized equipment, ensuring proper tire pressure, which is crucial for driving safety. Furthermore, car tire air pumps are suitable not only for car tires but also for other items that require air, such as balls and rubber boats.

[0003] The traditional air pump movement vibrates and makes a lot of noise during operation. The air pump sensor is installed externally, resulting in waste of materials and labor costs. The air pump bracket is an L-shaped structure, and the movement driven gear is below the motor gear. The product size is relatively large and takes up a large space.
