Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle-mounted air pump technology, and more specifically, to vehicle-mounted air pumps. Background Technology
[0002] A vehicle-mounted air pump, also known as an air inflator or tire inflator, works by the operation of an internal motor. When the motor is running and drawing air, the valve of the inflator is opened by atmospheric pressure, and air enters the cylinder. When inflating the tire, the valve is closed by the air pressure inside the cylinder, and air enters the tire. It uses the principle of atmospheric pressure to inflate cars, balls, and rubber boats. However, commonly used vehicle-mounted air pumps also have some drawbacks.
[0003] For example, a portable vehicle-mounted air pump disclosed in Chinese patent CN215566457U proposes that the motor inside the vehicle-mounted air pump is activated through the control panel, thereby pumping air into the object to be inflated. The rechargeable battery installed inside the vehicle-mounted air pump is used for power supply, avoiding the need for an external power source and increasing convenience. The air hose storage slot is designed for easy storage of the air hose, and the power supply storage slot is designed for easy storage of the power plug and the adapter nozzle, thus making the vehicle-mounted air pump easy to carry.
[0004] The aforementioned prior art uses an inflation tube storage slot to conveniently store the inflation tube at the bottom of the air pump. However, storing the inflation tube requires folding it according to the shape of the storage slot, and the lack of a fixing structure makes it prone to falling off, affecting its storage. Additionally, the LED lights used for illumination are located at the corners of the air pump, making them more susceptible to damage when the air pump is bumped or knocked.
[0005] Meanwhile, most commercially available vehicle-mounted air pumps of this type use a piston that moves repeatedly inside the air cylinder to complete the inflation operation. After long-term use, the piston will wear against the inner wall of the air cylinder, which will affect the sealing between the air cylinder and the piston, thus affecting the stability of the air source of the air pump, as well as the working efficiency of the air pump and reducing the service life of the air pump. Therefore, there is a need to propose a highly reliable vehicle-mounted air pump. Summary of the Invention
[0006] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a vehicle-mounted air pump. Through the coordinated use of a power component, an inflation component, and a lubrication component, the power component drives the inflation component to generate an air source for inflating tires. The lubrication component drips lubricating oil into the air cylinder of the inflation component, facilitating lubrication between the piston and the cylinder. This prevents wear and leakage between the piston and cylinder, ensuring the stability of the air source output of the vehicle-mounted air pump. Simultaneously, it prevents damage to the internal structure of the inflation component, extending the service life of the vehicle-mounted air pump and increasing its reliability, thus solving the problems mentioned in the background art.

[0014] An air inlet valve is installed inside the air piston, and an air cylinder is movable on the outer wall of the air piston.

The fixed column is fixedly connected to one side of the rotating plate, and the air cylinder is fixedly installed inside the fixed box.
[0015] In a preferred embodiment, the intake valve includes a movable column, and a limiting plate is movably connected to the outer wall of the movable column. The limiting plate is fixedly connected to the inside of the air piston, and a compression spring is fixedly installed on the outer wall of the movable column.
[0016] The bottom end of the movable column is fixedly connected to a sealing gasket, and the top of the sealing gasket is fitted to the bottom of the air piston. The compression spring is fixedly installed between the limiting plate and the sealing gasket, and the air piston has an air hole corresponding to the air inlet valve. The air inlet valve is installed inside the air hole.
[0017] In a preferred embodiment, the lubrication assembly includes a gear one, and a gear two meshes with one side of the gear one. An auxiliary structure is provided on one side of the gear two, and an oil pipe is installed on the top of the auxiliary structure. A connecting pipe is connected to the bottom of the auxiliary structure, and an oil outlet is fixedly connected to one end of the connecting pipe.
[0018] In a preferred embodiment, the oil outlet is fixedly connected to the top inner wall of the air cylinder, and the bottom of the air cylinder is fixedly connected to one end of the air filling pipe. The gear is fixedly connected to one end of the rotating rod. An air inlet valve is also installed inside the top of the oil pipe, and an air outlet valve is also installed at the bottom of the auxiliary structure. One end of the connecting pipe is located outside the air outlet valve.
[0019] In a preferred embodiment, the auxiliary structure includes a replenishing cylinder, and an oil piston is movably disposed on the inner wall of the replenishing cylinder. A pressing rod is fixedly connected to one side of the oil piston, and a movable baffle is fixedly installed at one end of the pressing rod.

The lubrication assembly drips lubricating oil into the air cylinder of the inflation assembly, thus facilitating lubrication between the air piston and the air cylinder. This prevents wear between the air piston and the air cylinder, which could cause air leakage, ensuring the stability of the air source output of the vehicle-mounted air pump. It also prevents damage to the internal structure of the inflation assembly, extending the service life of the vehicle-mounted air pump and increasing its reliability.
[0024] The design incorporates a storage box, a flip-top cover, and a magnetic fixing block, making it easy to store the inflation tube and power cord. This prevents the inflation tube and power cord from being placed outside the air pump, which would affect the portability of the air pump and improve its usability. Meanwhile, the disassembly plate is fixed to one side of the fixed box with screws. By removing the disassembly plate, the internal structure of the fixed box can be exposed, which facilitates subsequent maintenance of the vehicle-mounted air pump.
[0025] The use of a light box and a folding light allows for convenient use of the vehicle-mounted air pump at night. The folding light, which can be folded inside the light box, provides protection during operation, preventing the light from being directly exposed to the outside of the air pump and thus avoiding damage from impacts. This extends the lifespan of the folding light, while also allowing the vehicle-mounted air pump to be used at night, thereby improving its versatility. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] according to Figure 1-4 The vehicle-mounted air pump shown includes a fixed box 1, storage boxes 2 are provided on both sides of the fixed box 1, and a flip cover 3 is rotatably installed on one side of the storage box 2. An air inflator 4 is provided inside the storage box 2. A disassembly plate 5 is fixedly installed on one side of the fixed box 1, and a power assembly 6 is fixedly installed inside the fixed box 1.
[0038] Storage boxes 2 are symmetrically arranged on both sides of fixed box 1. A connecting magnetic block is fixedly connected to one side of flip cover 3, and a fixing magnetic block is fixedly connected to one side of storage box 2. Storage box 2 and flip cover 3 are magnetically connected through fixing magnetic block and connecting magnetic block. A power cord is installed inside storage box 2.
[0039] The power assembly 6 includes a motor 61, and a main gear 62 is fixedly connected to one end of the rotating shaft of the motor 61. A connecting gear 63 meshes with the bottom of the main gear 62, and a rotating rod 65 is fixedly connected inside the connecting gear 63.
[0040] One end of the rotating rod 65 is fixedly connected to a rotating plate 64. The motor 61 is fixedly connected to a fixing plate on the outside, and the motor 61 is fixedly installed inside the fixing box 1 through the fixing plate. The outer side of the rotating rod 65 is rotatably connected to a connecting plate, and the connecting plate is fixedly installed inside the fixing box 1.
[0041] The specific implementation method is as follows: the flip cover 3 is rotated and set on the side of the storage box 2, so as to facilitate the opening and closing of the storage box 2, thereby facilitating the storage and use of the inflation tube 4 and the power cord. The use of the fixing magnet and the connecting magnet makes it easy to fix the flip cover 3 to one side of the storage box 2, thereby facilitating the limiting of the inflation tube 4 and the power cord after storage.
[0042] This improves the portability of the vehicle-mounted air pump. Meanwhile, the disassembly plate 5 is fixed to one side of the fixed box 1 with screws. By removing the disassembly plate 5, the internal structure of the fixed box 1 can be exposed, which facilitates the subsequent maintenance of the vehicle-mounted air pump.
[0043] The fixed box 1 has an internal air pressure detection structure and a digital display screen on the outside of the fixed box 1, which makes it convenient to check the inflation pressure. This structure is existing technology and will not be described in detail.
[0044] according to Figure 4-6 The vehicle-mounted air pump shown has an inflation component 7 on one side of the power component 6;
[0045] When the power assembly 6 drives the inflation assembly 7 to inflate the tire, the internal structure of the power assembly 6 simultaneously drives the lubrication assembly 8 to be used, thereby lubricating the internal structure of the inflation assembly 7 and ensuring the stability of the gas output from the inflation assembly 7.
[0046] The inflation assembly 7 includes a fixed post 71, and a push rod 72 is rotatably connected to the outer wall of the fixed post 71. A shaft post 73 is rotatably connected to the bottom inner wall of the push rod 72, and an air piston 74 is fixedly connected to the outer side of the shaft post 73.
[0047] An air inlet valve 75 is installed inside the air piston 74, and an air cylinder 77 is movable on the outer wall of the air piston 74. An air outlet valve 76 is installed inside the bottom end of the air cylinder 77. The fixed column 71 is fixedly connected to one side of the rotating plate 64, and the air cylinder 77 is fixedly installed inside the fixed box 1.
[0048] The intake valve 75 includes a movable column 751, and a limiting plate 752 is movably connected to the outer wall of the movable column 751. The limiting plate 752 is fixedly connected to the inside of the air piston 74, and a compression spring 753 is fixedly installed on the outer wall of the movable column 751.
[0049] A sealing gasket 754 is fixedly connected to the bottom end of the movable column 751, and the top of the sealing gasket 754 is fitted to the bottom of the air piston 74. The compression spring 753 is fixedly installed between the limiting plate 752 and the sealing gasket 754, and the air piston 74 has an air hole corresponding to the air inlet valve 75. The air inlet valve 75 is installed inside the air hole.
[0050] The specific implementation method is as follows: the rotating plate 64 has an eccentric fan-shaped structure, and the fixed column 71 is set on one side of the rotating plate 64. As the rotating plate 64 rotates, the fixed column 71 will have a movement distance difference, which makes it convenient to drive the push rod 72 to move. The internal structure of the exhaust valve 76 and the intake valve 75 is the same, and thus the operating principle is the same. The exhaust valve 76 and the intake valve 75 are one-way valves, which facilitates the movement of the gas piston 74 to control the gas inlet and outlet.
[0051] Lubricating oil is dripped into the air cylinder 77 of the inflation assembly 7 through the lubrication component 8, which facilitates lubrication between the air piston 74 and the air cylinder 77. This prevents air leakage caused by wear between the air piston 74 and the air cylinder 77, thus ensuring the stability of the air source output of the vehicle-mounted air pump. At the same time, it avoids damage to the internal structure of the inflation assembly 7, thereby extending the service life of the vehicle-mounted air pump and increasing its high reliability.
[0052] according to Figure 7-9 The vehicle-mounted air pump shown has a lubrication component 8 on the other side of the power component 6 for lubricating the air inflation component 7. A light box 9 is installed on the top inner side of the fixed box 1, and a folding light 10 is rotatably installed inside the light box 9.
[0053] The lubrication assembly 8 includes a gear 81, and a gear 82 meshes with one side of the gear 81. An auxiliary structure 83 is provided on one side of the gear 82. An oil pipe 84 is installed on the top of the auxiliary structure 83. A connecting pipe 85 is connected to the bottom of the auxiliary structure 83. An oil outlet 86 is fixedly connected to one end of the connecting pipe 85.
[0054] The oil outlet 86 is fixedly connected to the top inner wall of the air cylinder 77, and the bottom of the air cylinder 77 is fixedly connected to one end of the air filling pipe 4. The gear 81 is fixedly connected to one end of the rotating rod 65. The top of the oil pipe 84 is also equipped with an air inlet valve 75, and the bottom of the auxiliary structure 83 is also equipped with an air outlet valve 76. One end of the connecting pipe 85 is located outside the air outlet valve 76.
[0055] The auxiliary structure 83 includes a replenishing cylinder 831, and an oil piston 832 is movably provided on the inner wall of the replenishing cylinder 831. An extrusion rod 833 is fixedly connected to one side of the oil piston 832, and a movable baffle 834 is fixedly installed at one end of the extrusion rod 833. A limit block 835 is movably connected to the outer wall of the movable baffle 834, and the limit block 835 is fixedly connected to the bottom of the replenishing cylinder 831.
[0056] A pressing column 836 is fixedly installed at the bottom of the movable folding plate 834, and a cam 837 is pressed on one side of the pressing column 836. A rotating rod 838 is fixedly connected inside one side of the cam 837. A cam 839 is provided on one side of the pressing column 836, and a rotating rod 838 is also provided inside the cam 839.
[0057] The rotating rods 838 are rotatably connected by a connecting belt, and one end of the rotating rod 838 is fixedly connected to one side of the gear 82. A frame plate is rotatably connected to the outside of the rotating rod 838, and the frame plate is fixedly installed inside the fixed box 1.
[0058] The specific implementation method is as follows: An air inlet valve 75 is provided inside the top side of the oil pipe 84 to facilitate the control of gas entering the oil pipe 84, thereby facilitating the downward flow of lubricating oil into the replenishment cylinder 831. At the same time, it works in conjunction with the air outlet valve 76 at the bottom of the replenishment cylinder 831 to facilitate the discharge of lubricating oil. The function is basically the same as that of the air inlet valve 75 of the air cylinder 77 and the air piston 74.
[0059] Meanwhile, a spring is provided on the outside of the extrusion rod 833, which facilitates the reset of the oil piston 832 after it moves. In conjunction with the extrusion of the second cam 839, the oil piston 832 is extruded with lubricating oil and then reset, which facilitates the repeated movement of the oil piston 832. At the same time, since the rotating rods 838 are connected by a connecting belt, the second cam 839 and the first cam 837 rotate simultaneously. The second cam 839 and the first cam 837 are set in the same direction, which facilitates the repeated pushing of the extrusion column 836 in an alternating manner.
[0060] The folding light 10 can be used for nighttime illumination of the vehicle-mounted air pump. At the same time, the folding light 10 can be folded inside the light box 9 for easy protection during operation, thereby preventing the folding light 10 from being directly exposed to the outside of the air pump and being damaged by bumps, thus improving the service life of the folding light 10.
[0061] The working principle of this invention is as follows: When inflating a tire, the flip cover 3 on one side of the storage box 2 is flipped open to take out the power cord and inflation tube 4 inside. Then, one end of the inflation tube 4 is clamped onto the tire inflation nozzle. After power is turned on, the motor 61 is turned on and used. Then, the main gear 62 drives the connecting gear 63 and the rotating plate 64 to rotate, thereby rotating the push rod 72 outside the fixed column 71 and the shaft column 73. Under the drive of the rotating plate 64, the air piston 74 moves up and down inside the air cylinder 77.
[0062] When the air piston 74 moves upward, the sealing gasket 754 of the intake valve 75 moves downward under the influence of air pressure, thereby allowing external air to enter the air cylinder 77. Then, when the air piston 74 moves downward again, the sealing gasket 754 of the intake valve 75 blocks the air hole upward, while the sealing gasket 754 of the outlet valve 76 is pushed downward, thereby allowing the gas inside the air cylinder 77 to enter the inflation pipe 4. During the repeated movement of the air piston 74, gas is continuously input into the inflation pipe 4 to inflate the tire.
[0063] While the connecting gear 63 rotates, the rotating rod 65 drives the first gear 81 to rotate, which in turn drives the second gear 82 to rotate the rotating rod 838. The rotation of the rotating rod 838 causes the first cam 837 to rotate on one side of the extrusion column 836. When the first cam 837 and the second cam 839 rotate at the same time, the extrusion column 836 is repeatedly squeezed left and right, which drives the moving baffle 834 to push the extrusion rod 833 to move left and right, so that the oil piston 832 draws the lubricating oil inside the oil pipe 84.
[0064] By pushing, lubricating oil is introduced into the connecting pipe 85 and into the air cylinder 77 through the oil outlet 86, so that the air piston 74 and the air cylinder 77 are lubricated during use, thereby avoiding air leakage due to wear of the air cylinder 77. When used at night, the folding lamp 10 can be rotated upward from inside the lamp box 9 to provide illumination.
