[0028] Example:

[0029] As attached Figure 1 To be continued Figure 8 As shown: This utility model provides a multifunctional miniature bicycle air pump, including an upper body 1 and a lower body 2, which are interlocked with the upper body 1. The upper body 1 includes an upper shell, and a fixing seat 104 is installed inside the upper shell. An inflation component, a drive component, and a control component are installed on one side of the fixing seat 104. A base plate 103 is installed at the bottom of the upper shell, and a power connection component is installed on the bottom side of the base plate 103. The lower body 2 includes a lower shell, and a storage battery 2010 is installed inside the lower shell. A connecting seat 203 and a lighting component 208 are respectively installed at the upper and lower ends of the lower shell. Multiple charging interfaces 205 and docking components connected to the power connection components are installed on the top side of the connecting seat 203.

[0030] The upper shell is composed of upper shell 101 and upper shell 2 102. The fixing base 104 and the bottom plate 103 are fixedly installed between upper shell 101 and upper shell 2 102. The sides of upper shell 101 and upper shell 2 102 are provided with multiple sets of anti-slip ridges. One side of upper shell 2 102 is provided with multiple sets of ventilation holes corresponding to the inflation component and the drive component. The split design of the upper shell facilitates the installation and maintenance of the internal core components. The anti-slip ridges effectively enhance the friction when gripping, prevent slippage during operation, and improve handheld stability and safety. The ventilation holes cooperate with the fan blades 1010 at the tail end of the micro motor 109 to form a forced air duct, which effectively dissipates the heat generated by the drive component during operation, ensures the stability and reliability of the equipment during long-term operation, and prevents overheating damage.

[0031] The inflation assembly includes a cylinder 105 fixedly mounted on one end of a fixed base 104. A piston 108 is slidably mounted inside the cylinder 105, and a connecting rod 107 is hinged to the bottom end of the piston 108. An inflation head 106 is connected to the top end of the cylinder 105. An inflation nozzle is provided at the top end of the inflation head 106, and a one-way exhaust valve is installed inside the inflation nozzle. An air inlet is provided on one side of the inflation head 106, and a one-way air inlet valve is installed inside the air inlet. The piston 108 is driven by the connecting rod 107 to reciprocate within the cylinder 105. In conjunction with the one-way air inlet valve and the one-way exhaust valve on the inflation head 106, efficient and reliable gas compression and directional delivery functions (intake → compression → exhaust) are achieved, ensuring that gas can only enter the cylinder in one direction and is finally output from the inflation nozzle to the tire, completing the basic inflation task.

[0032] The drive assembly includes a micro motor 109, a gear 1014, and a gear disk 1015. A connecting shaft is fixedly mounted on the eccentric part of the gear 1014, and the other end of the connecting rod 107 is rotatably connected to the connecting shaft. A transmission gear is provided at the center of the gear disk 1015, and the transmission gear meshes with the gear 1014. A gear 2 1016 is fixedly mounted on the outside of the motor shaft of the micro motor 109, and the gear 2 1016 meshes with the gear disk 1015. The micro motor 109 drives the gear disk 1015 to rotate through the gear 2 1016, and the gear disk 1015 then drives the gear 1014 to rotate through its central transmission gear. Due to the eccentric connecting shaft design of the gear 1014, the reciprocating linear motion of the piston 108 can be realized in conjunction with the connecting rod 107. This multi-stage gear transmission design effectively converts the high-speed rotation of the micro motor into the reciprocating linear motion required to drive the piston 108, and at the same time realizes torque amplification and motion form conversion through the gear set, ensuring stable and reliable power output required for inflation.

[0033] The other end of the motor shaft of the micro motor 109 extends out from the tail end of the micro motor 109 and is fixedly connected to the fan blade 1010. When the motor is working, the fan blade 1010 rotates synchronously to generate airflow. This airflow forms forced convection through the ventilation holes of the upper shell 102, actively expelling the heat generated by the drive components (especially the motor itself) from the outside of the shell, significantly improving the heat dissipation efficiency of the equipment, effectively preventing overheating, and ensuring the stable operation and lifespan of the equipment under high load or long-term inflation.

[0034] The control component includes a circuit board 1011, on one side of which a display screen 1012 and control buttons 1013 are mounted. The upper shell 101 has a display window corresponding to the display screen 1012, and buttons 1017 corresponding to the control buttons 1013 are mounted on the upper shell 1011. The circuit board 1011 is electrically connected to the micro motor 109 and the power connection component via wires. The power connection component is a pair of spring-loaded pins 1018, with one end of each pin located on the bottom outer side of the base plate 103. The circuit board 1011 is the core control unit for the inflation function. The display screen 1012 can display key information in real time through the display window, improving the intuitiveness and accuracy of user operation. The spring-loaded pins 1018, as power connection components, are located at the bottom of the base plate 103, providing reliable and easy-to-plug electrical connection points, contacting the lower body 2 docking component to enable the lower body 1 battery 2010 to supply power to the upper body.

[0035] The lower housing is composed of a lower housing 1 (201) and a lower housing 2 (202) joined together. The lighting component 208 includes a lamp plate snapped between the lower housing 1 (201) and the lower housing 2 (202). A lamp cover is fixedly installed on the bottom side of the lamp plate, and an LED is fixedly installed inside the lamp cover. The split design (lower housing 1 (201) and lower housing 2 (202)) facilitates the installation of internal components (such as batteries and circuit boards). The lighting component 208 (lamp plate + LED + lamp cover) is independently integrated at the bottom of the lower housing, which is suitable for providing direct and effective lighting for cycling surfaces and maintenance operation areas at night or in dim environments, significantly improving safety and convenience.

[0036] The bottom side of the connector 203 is fixedly mounted with a circuit board 204. The docking assembly consists of a pair of copper pillars 206, and the top of the copper pillars 206 is flush with the top of the connector 203. The copper pillars 206, the battery 2010, and the lamp board are electrically connected to the circuit board 204. The copper pillars 206, as docking assemblies, have their tops flush with the top surface of the connector and form a reliable, low-resistance electrical connection point with the spring pin 1018 at the bottom of the upper body, which is responsible for stably transmitting the power of the battery 2010 to the upper body 1.

[0037] The circuit board 204 has a switch 207 installed on one side, and the lower shell 201 has a through groove on one side for the switch 207 to be exposed. The switch provides users with a physical button interface to independently control the lower body lighting function, which makes it convenient for users to turn the lighting on or off separately when the upper body is not connected or the inflation function is not used. The operation is simple and direct.

[0038] The upper housing has a connection port at its bottom end that matches the connecting seat 203. Two sets of slots 1019 are symmetrically arranged on the inner wall of the connection port. Each slot 1019 is L-shaped, with its vertical section connected to the bottom end of the connection port, and its horizontal section having an arc-shaped protrusion. A locking block 209 is symmetrically arranged on the outer side of the connecting seat 203, and the bottom end of the locking block 209 has an arc-shaped groove that engages with the arc-shaped protrusion. The fit between the slot 1019 (L-shaped groove with arc-shaped protrusion) and the locking block 209 (with arc-shaped groove) is ingeniously designed. The locking block 209 first slides into position along the vertical section of the locking groove 1019, and then rotates 90 degrees so that the arc-shaped groove at the bottom of the locking block 209 and the arc-shaped protrusion on the horizontal section of the locking groove 1019 form an interlocking engagement. This design achieves a quick, stable and reliable physical connection between the upper and lower bodies, and can effectively prevent accidental loosening due to vibration or pulling during use. When separating, simply rotate in the opposite direction and lift it up, making the operation convenient.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
