[0002] An air pump, also known as an air inflator, an air pump, or an inflation pump, works by running a motor. When the motor is running, the valve of the communicating device is opened by the atmospheric pressure, and the gas enters the cylinder. When air is pumped into the tire, the valve is closed by the air pressure in the cylinder, and the gas enters the tire. That is, the principle of atmospheric pressure is used to inflate cars, motorcycles, bicycles, balls, etc., and the on-board air pump is the most commonly used vehicle auxiliary equipment. When an electric motorcycle cannot reach a maintenance point to inflate its tires, the on-board air pump can play a big role and bring great convenience to the driver.

[0003] Traditional vehicle-mounted air pumps are only equipped with an inflation nozzle. Since the inflation nozzle is not universal, the vehicle-mounted air pump cannot adapt to different vehicles or other equipment, which brings inconvenience to actual use. In addition, the existing vehicle-mounted air pump has a complex structure and occupies a large volume. Although the wires can be wrapped around the surface of the vehicle-mounted air pump, the outlet pipe and the outlet nozzle connected to the tire are relatively hard and cannot be stored. They are often exposed and are easily pressed by other items when stored, making it very inconvenient to take them out, which brings inconvenience to actual use. Utility Model Content

DETAILED DESCRIPTION

[0024] This specific embodiment is a vehicle-mounted air pump device for an electric motorcycle, and its structural schematic diagram is shown in FIG. Figure 1-Figure 5As shown, the device includes a first shell 6, a second shell 8, an inflation component 7, a one-way valve 2 and a pressure gauge 3. The second shell 8 is provided with an opening 13 corresponding to the pressure gauge 3. The inflation component 7 is installed inside the first shell 6 and the second shell 8. The output end of the inflation component 7 is connected to the one-way valve 2, and the output end of the one-way valve 2 is connected to the pressure gauge 3 and the connecting component 1. A notch 14 corresponding to the connecting component 1 is provided on the left side of the first shell 6 and the second shell 8. The notch 14 extends to the lower surface of the first shell 6 and the second shell 8 and is provided with a positioning groove 15. A card slot 16 is provided on the front of the first shell 6, and an auxiliary gas nozzle 4 is installed in the card slot 16.

[0025] like Figure 1 and Figure 3 As shown: In this embodiment, a switch 9, an input line 12 and a protective cover 10 are installed on the right side of the first shell 6 and the second shell 8. The input line 12 passes through the protective cover 10 and is electrically connected to the inflation assembly 7. A cigarette lighter plug is installed at the input end of the input line 12.

[0026] The input line 12 can be connected to the power supply of the motorcycle, and it is more convenient to use the cigarette lighter plug to get power. When in use, just press the switch 9, and the inflation component 7 will continue to work and inflate.

[0027] like Figure 3 and Figure 4 As shown: In this embodiment, the inflation component 7 includes a motor 701 installed inside the first shell 6 and the second shell 8, and the motor 701 can adapt to different battery voltages 36V-72V. The output end of the motor 701 is fixedly connected to the gear box 702, and the top left side of the gear box 702 is fixedly connected to the cylinder barrel 703, and the piston 704 is slidably connected inside the cylinder barrel 703. The right side of the gear box 702 is rotatably connected to the disc 706 through the rotating shaft 705. The output end of the motor 701 is located inside the gear box 702 and is fixedly connected to the pinion 707. The other end of the rotating shaft 705 is located inside the gear box 702 and is fixedly connected to the large gear 708. The small gear 707 is meshed with the large gear 708. The upper surface edge of the disc 706 is fixedly connected to the pin shaft 709, and the outer surface of the pin shaft 709 is rotatably connected to the connecting rod 710, and the other end of the connecting rod 710 is rotatably connected to the piston 704.

[0028] The motor 701 is arranged in this way to drive the small gear 707 to rotate. During the rotation process, the small gear 707 cooperates with the large gear 708 to drive the rotating shaft 705, the disk 706 and the pin 709 to rotate. During the rotation process, the pin 709 can drive the piston 704 to move in the cylinder barrel 703 through the connecting rod 710. When the piston 704 starts to move to the right from the inner dead point of the cylinder barrel 703, the volume in the cylinder barrel 703 gradually increases and the pressure decreases. At this time, the external gas rushes through the one-way valve 2 to open the intake valve and flows into the cylinder barrel 703 until the piston 704 reaches At the rightmost outer dead point, the intake valve of the one-way valve 2 begins to close. When it moves in the reverse direction, that is, when the piston 704 moves to the left, the volume is reduced, and the gas is compressed. When its pressure reaches a pre-designed level, the exhaust valve in the one-way valve 2 is opened, and the gas is discharged into the outlet pipe 101 until the piston 704 moves to the leftmost inner dead point, and the exhaust valve is closed. When the motor 701 keeps moving, the above process is repeated, and the process of intake, compression, and exhaust is realized in the cylinder barrel 703 in succession, that is, a working cycle is completed, and inflation is continued.

[0029] like Figure 1 and Figure 5 As shown: In this embodiment, the one-way valve 2 includes a one-way intake valve and a one-way exhaust valve, and the output end of the exhaust valve is fixedly connected to a bellows 201.

[0030] In this way, the pressure in the cylinder 703 is reduced. At this time, the external gas breaks through the intake valve along the one-way valve 2 and flows into the cylinder 703. When the piston 704 moves to the left, the volume is reduced and the gas therein is compressed. When its pressure reaches a pre-designed level, the exhaust valve in the one-way valve 2 is opened and the gas is discharged into the outlet pipe 101.

[0031] like Figure 1 and Figure 5 As shown: In this embodiment, the connecting component 1 includes an air outlet pipe 101 and an air outlet nozzle 102 connected to the air outlet pipe 101, and a soft nozzle 103 is fixedly connected to the air inlet end of the air outlet pipe 101.

[0032] The soft nozzle 103 arranged in this way can be plugged together with the bellows 201, which is very convenient to install and will not cause air leakage.

[0033] like Figure 1 and Figure 2 As shown: In this embodiment, the first shell 6 and the second shell 8 are fixedly connected to the front and rear sides with the first U-shaped rubber strip 5 and the second U-shaped rubber strip 11 respectively.

[0034] The first U-shaped rubber strip 5 and the second U-shaped rubber strip 11 can protrude from the outer surfaces of the first shell 6 and the second shell 8, and the friction force can be increased when the on-board air pump device of the electric motorcycle is placed, thereby avoiding movement and achieving better stability.

[0035] Working principle: A slot 16 is provided on the front of the first housing 6, and an auxiliary air nozzle 4 is installed in the slot 16. The auxiliary air nozzle 4 can be easily taken out from the slot 16. Different air nozzles can be selected according to the type of vehicle, tire type or other equipment to meet the different needs of users. When in use, the air outlet nozzle 102 is connected to the component that needs to be inflated, the input line 12 is connected to the power supply of the motorcycle, and then the switch 9 is pressed. At this time, the motor 701 drives the small gear 707 to rotate, and the small gear 707 rotates with the large gear The wheel 708 cooperates to drive the rotating shaft 705, the disk 706 and the pin 709 to rotate. During the rotation process, the pin 709 can drive the piston 704 to move in the cylinder 703 through the connecting rod 710. When the piston 704 starts to move to the right from the inner dead point of the cylinder 703, the volume in the cylinder 703 gradually increases and the pressure decreases. At this time, the external gas rushes through the one-way valve 2 to open the intake valve and flows into the cylinder 703 until the piston 704 reaches the rightmost outer dead point. At this time, the intake valve of the one-way valve 2 begins to close. When the piston 704 moves to the left, the volume is reduced, and the gas is compressed. When its pressure reaches a predetermined level, the exhaust valve in the one-way valve 2 is opened, and the gas is discharged into the outlet pipe 101 until the piston 704 moves to the leftmost inner dead point, and the exhaust valve is closed. When the motor 701 keeps moving, the above process is repeated, and the cylinder barrel 703 successively realizes the process of intake, compression, and exhaust, that is, a working cycle is completed, and the inflation is continued. After use, the input line 12 can be wound around the surface of the vehicle-mounted air pump, and the air outlet nozzle 102 is bent along the notch 14. Since the notch 14 extends to the lower surfaces of the first shell 6 and the second shell 8 and is provided with a positioning groove 15, the notch 14 is an overall L-shaped structure at this time, the air outlet pipe 101 can be completely bent in the notch 14, and the air outlet nozzle 102 is clamped in the positioning groove 15, so that the air outlet pipe 101 and the air outlet nozzle 102 are stored to avoid being exposed to the outside, and will not be pressed by other items when stored, and it is very convenient to take out when actually using it.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
