[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3 The present invention provides an embodiment of a portable vehicle-mounted air pump, comprising a small air pump 1. The small air pump 1 is made of high-strength engineering plastic, which is not only lightweight and portable but also has excellent wear and impact resistance, effectively protecting the precision components within. A button 2 is fixedly attached to the front end of the pump. This button 2 is designed with distinct tactile feedback for user convenience; pressing it accurately starts or stops the pump.

[0033] The top of the small air pump 1 is fixedly connected to an air pipe 17. Made of highly elastic rubber, this pipe is extremely flexible and can be bent easily without breaking, adapting to various usage scenarios and angles. The top of the pipe 17 is rotatably connected to a connecting column 3. This column is made of a rigid aluminum alloy, which is durable and resistant to deformation, ensuring stability during connection and inflation. A retaining ring 4 is fixedly attached to the inside of the connecting column 3. This metal retaining ring 4 is designed to securely hold internal components and withstand pressure.

[0034] Multiple springs 5 ​​are fixedly attached to the interior of the retaining ring 4. Made from high-quality stainless steel spring wire, these springs possess excellent elasticity and durability, maintaining stable performance during repeated compression and rebound. A fixing block 7 is fixedly attached to the exterior of the connecting column 3. The anti-slip surface of the fixing block 7 ensures a secure fit and prevents slipping during component connection.

[0035] The top of the connecting column 3 is slidably connected to a hollow column 8, which is also made of a hard aluminum alloy. A slot is defined within the hollow column 8, and the outer side of the fixing block 7 is slidably connected to the slot. Two limiting rings 18 are fixedly connected to the interior of the hollow column 8. These effectively limit the position of the connecting column 3 and assist in sealing. The top of the fixing ring 4 is slidably connected to the bottom of one of the limiting rings 18, and the bottom of one of the limiting rings 18 is slidably connected to a sealing ring 6. The sealing ring 6 is made of highly elastic rubber, providing a good sealing effect and effectively preventing gas leakage. The outer side of the sealing ring 6 is slidably connected to the interior of the fixing ring 4, and the top of the spring 1 5 is fixedly connected to the bottom of the sealing ring 6.

[0036] Reference Figure 2 、 Figure 4The rear side of the small air pump 1 is fixedly connected to a storage component for storing the power cord. A plurality of fixed plates 11 are fixedly connected inside the storage component. The fixed plates 11 are made of plastic and serve to support and fix other components. The internal rotation of the fixed plate 11 is connected to a limiting component for limiting the power cord.

[0037] The storage assembly includes a storage box 9, which is made of hard plastic and provides a certain degree of protection, protecting the internal power cord from external collisions and compression. One side of the storage box 9 is fixedly connected to the rear end of the small air pump 1. A lid 10 is rotatably connected to one side of the storage box 9. The lid 10 is tightly connected to the storage box 9. A buckle 16 is fixedly connected to the outside of the lid 10, which can firmly fix the lid 10 to the storage box 9 and prevent it from accidentally opening while the vehicle is in motion.

[0038] The limiting component includes two clamping plates 12, which are made of plastic material and have a certain elastic rubber coating on the surface. They can effectively clamp the power cord without causing damage to the power cord. The outer sides of the two clamping plates 12 are rotatably connected to the inside of the fixed plate 11, and the inner sides of the two clamping plates 12 are rotatably connected to a limiting block 13. The limiting block 13 can limit the rotation range of the clamping plates 12 to ensure that the clamping force on the power cord is moderate. The outer sides of the limiting block 13 are rotatably connected to the inside of the fixed plate 11, and the outer sides of the clamping plates 12 are fixedly connected to a connecting plate 14. The connecting plate 14 serves to connect the clamping plates 12 and a spring 2 15. The inner side of the connecting plate 14 is fixedly connected to a spring 2 15. The spring 2 15 is made of spring steel wire with moderate elasticity and can provide a stable rebound force. The other end of the spring 2 15 is fixedly connected to the inside of the fixed plate 11.

[0039] Working principle: When the user needs to charge the small air pump 1, he can buckle the buckle 16 from the inside of the storage box 9, so that the cover 10 is free from the restriction, and the cover 10 can be opened. At this time, the power cord can be taken out. After use, the power cord can be folded again and placed inside the two splints 12. When the outer side of the power cord contacts the splint 12, the splint 12 will be squeezed to both sides. When it reaches the appropriate position, the power cord can be placed between the two splints 12. At this time, the splint 12 will be squeezed away because the power cord enters its inner side, and the splint 12 will be pushed back to its original position by the rebound force provided by the spring 2 15, thereby restricting the power cord.

[0040] When the user needs to inflate a tire, inner tube or other things, the user can install the hollow column 8 at the place where inflation is required, and the interior of the hollow column 8 is fixedly connected with a limiting ring 18. The user only needs to press the hollow column 8 hard on the outside of the tire's inflation port, and the limiting ring 18 will squeeze the hollow column 8, so that the hollow column 8 and the outside of the inflation port are tightly connected. At this time, the user can slide the outside of the connecting column 3 into the inside of the hollow column 8, and then rotate the connecting column 3, so that the fixing block 7 slides into the slot opened inside the hollow column 8, and the connection The interior of the column 3 is connected to a fixing ring 4, and the interior of the fixing ring 4 is connected to multiple springs 5. The top of the spring 5 is connected to a sealing ring 6. When the connecting column 3 slides into the interior of the hollow column 8, the top of the sealing ring 6 will contact the bottom of one of the limiting rings 18. At this time, the sealing ring 6 will continuously squeeze it, thereby pressing the spring 5 downward. When the fixing block 7 is rotated to the inside of the card slot inside the hollow column 8, the connecting column 3 is released and the spring 5 will provide a rebound force, thereby firmly connecting the connecting column 3 and the hollow column 8 together.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
