[0002] When cycling outdoors, it is often necessary to carry a variety of tools such as a bicycle headlight, taillight, power bank, and emergency air pump. However, in traditional cycling equipment, the headlight, taillight, charging equipment, and air pump are all independent components, with functions scattered and taking up a lot of space. Due to the lack of structural integration, the various functional modules cannot work together, requiring users to frequently switch between devices, making them very inconvenient to use and store. Utility Model Content

[0003] This application provides a multifunctional inflatable cycling lighting device to solve the technical problem that existing cycling equipment lacks structural integration of its various functional modules, making them unable to work together and requiring users to frequently switch between devices, resulting in great inconvenience in both use and storage.

[0004] This application provides a multifunctional inflatable cycling lighting device, comprising:

[0005] The housing includes an upper housing and a lower housing, which are detachably connected;

[0006] The headlight module includes a first light component, a first power supply component, and an air pipe. The first light component is electrically connected to the first power supply component, and the first light component, the first power supply component, and the air pipe are all housed within the lower housing.

[0007] The taillight module includes a second light component, a second power supply component, and an air pump. The second light component is electrically connected to the second power supply component, and the second light component, the second power supply component, and the air pump are all housed within the upper housing.

[0008] The headlight module and the taillight module are electrically connected.

[0009] Furthermore, the first lighting assembly includes a first circuit board and a lamp reflector. The lamp reflector is electrically connected to the first circuit board. The first circuit board is located on one side of the lamp reflector. The lamp reflector is located on the side of the lower housing and is directly connected to the external space.

[0010] Furthermore, the first power supply component includes a main circuit board and a plurality of batteries arranged in an array, the batteries being electrically connected to the main circuit board, and the main circuit board being electrically connected to the first circuit board.

[0011] Furthermore, the top of the lower housing is provided with a first cover plate, and one side of the first cover plate is provided with an arc-shaped groove, into which the air pipe is snapped.

[0012] Furthermore, the second lighting component includes a second circuit board and a lamp board, the lamp board being electrically connected to the second circuit board, and the second circuit board being connected to the second power supply component.

[0013] Furthermore, the air pump is installed below the second lighting component, the air pump is detachably connected to the upper housing and electrically connected to the second power supply component, and the air inlet of the air pump passes through one side wall of the upper housing and communicates with the external space.

[0014] Furthermore, the air pump has an intake fan at its air inlet end, and the upper housing has several heat dissipation holes evenly arranged around the intake fan shaft on the side near the intake fan.

[0015] Furthermore, the bottom of the upper housing is provided with a second cover plate, which is magnetically connected to the first cover plate. One side of the second cover plate is provided with a third circuit board, which is electrically connected to the second power supply component. The other side of the second cover plate is provided with a mounting groove, in which a data cable is provided.

The mounting ring is fixedly connected to the bottom of the mounting compartment. Both the front light module and the taillight module can be detachably installed in the mounting compartment. When the taillight module is installed in the mounting compartment, the heat dissipation holes are closed by the mounting compartment.

[0018] The technical solution provided in this application has the following advantages compared with the prior art:

[0019] This application solves the problems of fragmented functions and cumbersome operation of cycling equipment by integrating the headlight and taillight modules into detachable upper and lower housings, each with its own independent power supply components, air pump, and air hose. Specifically, the headlight and taillight modules are electrically connected to achieve coordinated power supply and functional linkage. For example, the headlight illumination and taillight warning can work simultaneously, and the air pump and air hose work together to achieve rapid inflation. The detachable design of the upper and lower housings ensures the integrity of the device (used as an integrated unit during riding) while also allowing for separate maintenance or adjustment of the installation position as needed (e.g., using only the headlight or inflation function). Therefore, users do not need to carry separate equipment to meet the needs of multiple scenarios such as cycling lighting, safety warnings, and tire inflation, significantly improving functional integration and ease of use.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] To address the technical problem of existing cycling equipment lacking structural integration and unable to work collaboratively, requiring users to frequently switch between devices, resulting in inconvenience in both use and storage, this application provides a multi-functional cycling inflatable lighting device. This application solves the problems of fragmented functions and cumbersome operation of cycling equipment, allowing users to meet the needs of multiple scenarios such as cycling lighting, safety warnings, and tire inflation without having to carry separate equipment, significantly improving functional integration and ease of use.

[0039] Please see Figures 1 to 7 This application provides a multifunctional inflatable cycling lighting device, comprising: a housing 1, which includes an upper housing 11 and a lower housing 12, which are detachably connected; a front light module 2, which includes a first light component 21, a first power supply component 22, and an air pipe 23, wherein the first light component 21 is electrically connected to the first power supply component 22, and the first light component 21, the first power supply component 22, and the air pipe 23 are all housed within the lower housing 12; and a taillight module 3, which includes a second light component 31, a second power supply component 32, and an air pump 33, wherein the second light component 31 is electrically connected to the second power supply component 32, and the second light component 31, the second power supply component 32, and the air pump 33 are all housed within the upper housing 11; the front light module 2 and the taillight module 3 are electrically connected.

[0040] Specifically, the upper housing 11 and the lower housing 12 are detachably connected via a snap-fit ​​or magnetic structure. The lower housing 12 integrates a first lighting component 21 (such as a white LED), a first power supply component 22, and an air tube 23, with the end of the air tube 23 adapted to a bicycle valve. The upper housing 11 integrates a second lighting component 31 (such as a red LED), a second power supply component 32, and an air pump 33, which can be connected to the air tube 23 of the lower housing 12. After the upper and lower housings 12 are assembled, the headlight and taillight can work independently or synchronously. The air pump 33 inflates the tires through the air tube 23, and the power supply component can charge external devices. This method integrates lighting, inflation, and power bank functions, avoiding the need to carry multiple independent devices while riding, thus saving storage space. The power supply components of the front and rear modules serve as backups for each other, ensuring basic functionality even when a single module's power is insufficient.

[0041] like Figures 1-2 and Figure 6 As shown, the first lighting assembly 21 includes a first circuit board 211 and a lamp cup 212. The lamp cup 212 is electrically connected to the first circuit board 211. The first circuit board 211 is located on one side of the lamp cup 212. The lamp cup 212 is located on the side of the lower housing 12 and is directly connected to the external space.

[0042] Specifically, the lamp cup 212 is molded from a light-transmitting material (such as polycarbonate), and its open end is embedded in the side opening of the lower housing 12, directly communicating with the external space; the inner wall of the lamp cup 212 is provided with a reflective coating to enhance the light-gathering effect; the first circuit board 211 is connected to the light source (such as LED beads) inside the lamp cup 212 through wires or flexible circuits, driving the light source to emit light and projecting light to the side and front through the lamp cup 212; the first circuit board 211 is located on one side of the lamp cup 212 and is fixed to the inner wall of the lower housing 12 by screws or clips.

[0043] Furthermore, such as Figure 2 As shown, a sealing element 213 is fitted on the lamp cup 212. The sealing element 213 is an annular elastic material (such as silicone or rubber), which is tightly fitted between the outer wall of the lamp cup 212 and the mounting hole on the side of the lower housing 12. It is fixed by interference fit or snap-fit ​​structure, covering the assembly gap between the lamp cup 212 and the housing 1, forming a waterproof and dustproof barrier.

[0044] like Figure 2 and Figure 6 As shown, the first power supply component 22 includes a main circuit board 221 and a plurality of batteries 222 arranged in a row. The batteries 222 are electrically connected to the main circuit board 221, and the main circuit board 221 is electrically connected to the first circuit board 211.

[0045] Specifically, in the first power supply component 22, several batteries 222 are fixed in a matrix arrangement within the lower housing 12 and connected to the positive and negative contacts of the main circuit board 221 via metal springs or flexible wires. The main circuit board 221 integrates a charge / discharge management unit and protection circuit, and is connected to the first circuit board 211 via a ribbon cable or plug-in port to achieve power distribution and light control signal transmission. The arrangement of the battery groups 222 optimizes space utilization, and the main circuit board 221 centrally manages power output, ensuring stable operating voltage for the first lighting component 21. The main circuit board 221 has a built-in overcharge / over-discharge protection mechanism to prevent malfunctions caused by abnormal battery conditions.

[0046] like Figure 1 and Figure 6 As shown, the top of the lower housing 12 is also provided with a first cover plate 121, and an arc-shaped groove 1211 is provided on one side of the first cover plate 121, and the air pipe 23 is snapped into the arc-shaped groove 1211.

[0047] Specifically, a first cover plate 121 is installed on the top of the lower housing 12 via a snap-fit ​​structure. An arc-shaped groove 1211 is formed on the inner side of the cover plate, the curvature of which matches the outer diameter of the air tube 23. The inner wall of the groove is provided with anti-slip texture or elastic protrusions. The air tube 23 is embedded in the groove. When the cover plate is closed, the air tube 23 is fixed by the arc-shaped limit of the groove and the pressure of the cover plate, preventing it from shifting or loosening. The arc-shaped groove 1211 adapts to the shape of the air tube 23, enabling quick storage and fixation, preventing the air tube 23 from swinging randomly or getting tangled in other parts during riding. At the same time, the air tube 23 can be directly accessed or stored by opening and closing the cover plate without disassembling the housing 1 or other components, improving usage efficiency.

[0048] like Figures 1-2 As shown, the second lighting assembly 31 includes a second circuit board 311 and a lamp board 312. The lamp board 312 is electrically connected to the second circuit board 311, and the second circuit board 311 is connected to the second power supply assembly 32.

[0049] Specifically, the second circuit board 311 is fixed to the inner wall of the upper housing 11, and the lamp board 312 (such as a strip light with multiple LEDs) is connected to the second circuit board 311 through a flexible wire; the second power supply component 32 is a single battery 222, which is connected to the power interface of the second circuit board 311 through a metal spring or wire; the second circuit board 311 integrates a control unit, which triggers the working mode of the lamp board 312 (such as constant light or flashing) through a switch or wireless signal.

[0050] like Figure 2 and Figure 4 As shown, the air pump 33 is installed below the second lighting assembly 31. The air pump 33 is detachably connected to the upper housing 11 and electrically connected to the second power supply assembly 32. The air inlet of the air pump 33 passes through one side wall of the upper housing 11 and communicates with the external space.

[0051] Specifically, the air pump 33 is fixed to the second lighting component 31 inside the upper housing 11 by screws or clips. The air pump 33 is provided with a connection terminal, which is connected to the corresponding interface of the second power supply component 32 inside the upper housing 11 to realize quick disassembly and power transmission. The air inlet of the air pump 33 extends to the through hole on the side wall of the upper housing 11. The through hole is embedded with a sealing ring. The exposed part of the air inlet is equipped with a dust cover. When inflating, the dust cover is removed and the air pipe 23 is connected for use. The air pump 33 can be disassembled separately for easy replacement or cleaning in case of failure, without disassembling the entire taillight module 3.

[0052] like Figures 2-4 As shown, the air pump 33 has an air intake fan 331 at its air inlet end, and the upper housing 11 has several heat dissipation holes 111 evenly distributed around the rotating shaft of the air intake fan 331 on the side near the air intake fan 331.

[0053] Specifically, the air intake end of the air pump 33 is fixed to the intake fan 331 via a flange or clip. The fan shaft is coaxially connected to the compression chamber of the air pump 33. When the fan blades rotate, they directly drive external air into the air pump 33 for compression. The upper housing 11 has a ring-shaped array of heat dissipation holes 111 near the intake fan 331. The holes are elongated or circular in shape and are evenly distributed at equal angles along the circumference of the fan shaft. The holes penetrate the inner and outer walls of the housing 1 and communicate with the external air. When the intake fan 331 is running, external air is actively drawn in through the heat dissipation holes 111, pressurized by the fan, and then introduced into the compression chamber of the air pump 33, finally outputting a high-pressure airflow from the outlet. In this way, the intake airflow can simultaneously carry away the heat generated by the motor of the air pump 33 during compression, avoiding performance degradation due to overheating. Simultaneously, the heat dissipation holes 111 are integrated into the air intake path of the air pump 33, eliminating the need for additional heat dissipation ducts and optimizing the space utilization of the housing 1.

[0054] like Figures 2-3 and Figure 6 As shown, the bottom of the upper housing 11 is provided with a second cover plate 112, which is magnetically connected to the first cover plate 121. One side of the second cover plate 112 is provided with a third circuit board 113, which is electrically connected to the second power supply component 32. The other side of the second cover plate 112 is provided with a mounting groove 1121, and a data cable 1122 is provided in the mounting groove 1121.

[0055] Specifically, the bottom of the upper housing 11 is detachably connected to the second cover plate 112 via a magnetic structure. The side of the second cover plate 112 facing the inside of the housing 1 is fixed with a third circuit board 113. This circuit board is electrically connected to the second power supply component 32 via elastic contacts or plug terminals. The mounting groove 1121 on the outside of the second cover plate 112 is a groove or slide rail structure. The groove is provided with elastic buckles or Velcro for fixing folded or coiled data cables 1122 (such as USB cables). The third circuit board 113 integrates a wireless charging management module, which supports the data cable 1122 to provide power or transmit data.

[0056] like Figures 2-6 As shown, the third circuit board 113 has a first USB interface 1131 and a USB plug 1132 at its two ends respectively. The first USB interface 1131 passes through the upper housing 11 and communicates with the external space. The USB is rotatably connected to the third circuit board 113 via a connecting cable. One end of the first circuit board 211 has a second USB interface 2111. The second USB interface 2111 passes through the first cover plate 121. By rotating the USB plug 1132, the USB plug 1132 can be plugged into the second USB interface 2111.

[0057] Specifically, the third circuit board 113 is fixed inside the second cover plate 112. One end of the circuit board integrates a first USB interface 1131 (such as a Type-C female connector). This interface passes through a through hole in the side wall of the upper housing 11 and is exposed. The other end is connected to a flexible PCB or cable through a rotating shaft, and the end is fixed with a USB plug 1132 (such as a Type-A male connector), so that the plug can rotate 180° around the shaft. A through hole is provided on the first cover plate 121. The second USB interface 2111 (such as a Type-C female connector) is embedded in the hole and sealed and fixed thereto. The interface pins are soldered to the first circuit board 211. When the USB plug 1132 is rotated to a specific angle, its plug end is aligned and plugged into the second USB interface 2111, thus completing the electrical connection between the third circuit board 113 and the first circuit board 211.

[0058] like Figure 5 and Figure 7 As shown, the multi-functional cycling inflatable lighting device also includes a mounting bracket 4. The mounting bracket 4 includes a mounting chamber 41 and a mounting ring 42. The mounting ring 42 is fixedly connected to the bottom of the mounting chamber 41. Both the front light module 2 and the taillight module 3 can be detached and installed in the mounting chamber 41. When the taillight module 3 is installed in the mounting chamber 41, the heat dissipation hole 111 is closed by the mounting chamber 41.

[0059] Specifically, the mounting compartment 41 is a box-shaped structure with an open top, and has multiple sets of elastic clips or slide rails inside to adapt to the external dimensions of the front light module 2 and the taillight module 3, enabling quick snap-fit ​​fixation. The mounting ring 42 is connected to the bottom of the mounting compartment 41 by bolts or quick-release buckles, and the diameter of the ring is adjustable to fit the bicycle frame or handlebars. When the taillight module 3 is installed into the mounting compartment 41, the raised baffle or sealing gasket on the inner wall of the mounting compartment 41 fits tightly against the heat dissipation hole 111 area of ​​the upper housing 11, completely blocking the heat dissipation hole 111. When the front light module 2 is installed, the baffle automatically avoids it due to the difference in module shape, and the heat dissipation hole 111 remains open. The sealing of the heat dissipation hole 111 in the mounting compartment 41 only takes effect when the taillight module 3 is in use, preventing dust / rainwater from entering through the heat dissipation hole 111 during riding, while ensuring unobstructed heat dissipation when the front light module 2 is in use.
