Description

Technical Field

[0001] This utility model relates to an air pump, and more particularly to a low-friction coefficient vehicle air pump, belonging to the field of air pump technology. Background Technology

[0002] A car tire inflator is a portable tool specifically designed for inflating car tires and is an essential emergency item for modern car owners. It works by using an electric motor to drive a cylinder piston in a reciprocating motion, compressing air and injecting it into the tire to quickly increase tire pressure. Common car tire inflators come in two types: portable and pedal-operated. Portable inflators are usually powered by the car's cigarette lighter socket or battery, are easy to operate, compact, and convenient to carry in the vehicle. Pedal-operated inflators, on the other hand, require no power source and are inflated by manually stepping on the pedal, making them suitable for emergency use in situations without power.

[0003] In practical use, the significant friction between the cylinder piston and the air pump in a car results in a substantial increase in operating current. To meet the power demand for this high current, car air pumps must be equipped with batteries of larger capacity and size. However, the installation of a larger battery increases the overall size of the air pump, contradicting the original design goal of making it compact and portable. This not only occupies more storage space in the car but also reduces its portability. Therefore, a car air pump with a low coefficient of friction is proposed. Utility Model Content

The air pump assembly 20 includes a cylinder 21, a composite coating 22, a piston 23, a drive rod 24, a connecting rod 25, a rotating disk 27, a drive motor 28, an air pressure sensor 29, an air outlet 210, an air inlet pipe 213, and a filter 214.

[0027] The inner wall of cylinder 21 is coated with a composite coating 22. A piston 23 is slidably connected to the inner wall of cylinder 21. A drive rod 24 is fixedly connected to the bottom of piston 23. A connecting rod 25 is rotatably connected to the bottom end of drive rod 24. A rotating disk 27 is rotatably connected to one end of connecting rod 25. The rotating disk 27 is fixedly connected to the output shaft of drive motor 28. A pressure sensor 29 is installed on cylinder 21. An air outlet 210 is connected to the top of cylinder 21. An air inlet pipe 213 is connected to the outer wall of cylinder 21. One end of air inlet pipe 213 is equipped with... There is a filter 214, which can filter dust during air intake and prevent dust from affecting the friction between the inner wall of cylinder 21 and piston 23. The inner wall of cylinder 21 is treated with a diamond-like carbon and tungsten disulfide material coating to improve the smoothness and wear resistance of the inner wall of cylinder 21. The composite coating 22 is made of low friction composite material, which can effectively reduce the friction between piston 23 and cylinder 21 during the operation of air pump, reduce energy consumption and high current requirements, thereby reducing the overall size of battery 18 and air pump, making it convenient to carry and use.

[0028] In this embodiment, specifically: one end of the air outlet 210 is threadedly connected to a connecting pipe 211, and one end of the connecting pipe 211 is fixedly connected to a connector 212.

[0029] In this embodiment, specifically: the air pumping component 20 is provided with a main body component 10 on its exterior, and the main body component 10 includes a housing 11, an end cap 12 and an operation panel 13;

[0030] An end cap 12 is fixedly connected to the top of the housing 11 by bolts. An operation panel 13 is installed on the front surface of the housing 11. A pressure sensor 29 is connected to the operation panel 13. The probe of the pressure sensor 29 is located inside the cylinder 21 to detect the internal pressure value of the cylinder 21.

[0031] In this embodiment, specifically: the cylinder 21 is fixedly connected to the bottom of the end cover 12 by bolts, which facilitates the disassembly and maintenance of the cylinder 21.

[0032] In this embodiment, specifically: a display screen 14 and operation buttons 15 are installed on the front surface of the operation panel 13, and the display screen 14 and operation buttons 15 make it convenient for users to use the operation panel 13.

[0035] In this embodiment, specifically: a battery 18 is installed on the inner sidewall of the housing 11, and the battery 18 is used to provide power to the air pump.

[0036] In operation, the inner wall of cylinder 21 is coated with diamond-like carbon and tungsten disulfide materials to improve its smoothness and wear resistance, eliminating the need for additional lubricant to reduce friction. When the air pump is pumping air, the drive motor 28 drives the rotating disk 27 to rotate, and the connecting rod 25 drives the drive rod 24 and piston 23 to slide on the inner wall of cylinder 21, delivering gas through the outlet 210 to the connecting pipe 211 and connector 212 to complete the pumping operation.
