Technical Field
[0001] This invention relates to the field of air pumps, and more specifically to a lithium-ion battery-powered air pump with lighting function. Background Technology
[0002] Air pumps can be divided into mechanical and electric types. With technological advancements, electric air pumps are becoming increasingly widely used; in particular, the rapid development of lithium battery technology has provided solid support for the portability of small air pumps for cycling.
[0003] However, while some existing lithium-ion air pumps offer good portability, they still have several shortcomings. For example, when the air pump is detached from the bicycle, it adds an extra burden to the rider; even if some products can be installed on the bicycle frame using universal connectors, there is still a risk of loosening or detachment due to insufficient tightness in the connection. In addition, long-distance riding often relies on bicycle lights for illumination, but if the lights and air pump are designed separately, it will create redundant space in the limited bicycle space, which also constitutes a pain point in use. Summary of the Invention
[0004] The purpose of this invention is to provide a lithium-ion battery-powered air pump with lighting function, thereby solving the above-mentioned technical problems.
[0005] The objective of this invention can be achieved through the following technical solutions:
[0006] A lithium-ion battery-powered air pump with lighting function includes: a housing, an air pump assembly built into one side of the housing, an outdoor lighting assembly integrated into the other side, a battery pack disposed in the middle of the housing for powering the air pump assembly and the outdoor lighting assembly, and a handlebar fixing mechanism disposed at the bottom of the housing for fixing the air pump to the handlebar.
[0007] Furthermore, the handlebar fixing mechanism includes:
[0008] The first fixing component is used to initially fix the air pump to the handlebars;
[0009] The second fixing component is used to reinforce the initially fixed shell and can be quickly loosened as needed.
[0010] Furthermore, the first fixing component includes an adjustable arc-shaped clamp that adapts to handlebars of different diameters; a rubber pad layer is filled on the inner side of the arc-shaped clamp in contact with the handlebar.
[0011] The limiting unit is used to limit the movement on both sides after the rubber pad layer is filled.
[0012] Furthermore, the second fixing component includes a knob that is rotatably passed through the bottom of the housing via an axial bearing. The knob is exposed on the lower surface of the housing, and a winding wheel is coaxially fixed to the inner end of the knob. One end of the wire rope is fixed to the winding groove of the winding wheel, and the other end passes through the through hole in the side wall of the housing, the connecting ring on the arc-shaped clamp, and then connects to the swingable hook.
[0013] When the knob is rotated in one direction, it drives the winding wheel to wind and tighten the steel wire rope, so that the hook engages with the U-shaped groove of the pre-set anchor point on the arc-shaped clamp; after the knob is pulled outward, the ratchet lock inside the winding wheel is released, and the steel wire rope is released by rotating in the opposite direction; the O-ring is nested at the center of the knob shaft, and the entire winding wheel is covered in the waterproof cover cavity that is integrally formed with the housing.
[0014] Furthermore, a rainproof mechanism is provided on the outside of the housing to protect the exposed interfaces on the housing.
[0015] Furthermore, the rainproof mechanism includes two parallel guide rails, which are set at the exposed interface of the housing. A cover is slidably connected to the guide rail, and the outer surface of the cover is provided with protruding ridges. Iron rings are provided at the exposed interface of the housing, and permanent magnets are provided on the covers. The permanent magnets cooperate with the iron rings to form a magnetic attraction structure for the covers.
[0016] Furthermore, the limiting unit includes two sets of limiting blocks that slide symmetrically inside the arc-shaped clamp, and a transmission unit that connects to the knob in the second fixing assembly.
[0017] When the knob is rotated, the transmission unit synchronously drives the two sets of limit blocks to move radially along the arc-shaped clamp, thereby clamping and limiting or releasing the rubber pad on both sides.
[0018] Furthermore, the transmission unit includes a push rod, the bottom of which abuts against the top of the limiting block, and the top of which contacts the bottom of the annular groove. The annular groove is formed on the outer periphery of the winding wheel, and the depth of the annular groove gradually decreases along the direction of twisting and tightening.
[0019] Furthermore, a display screen is provided on the top of the housing, and an air pump switch is provided on one side of the display screen. The air pump switch is electrically connected to the air pump assembly. A lighting switch is provided on one side of the housing. The lighting switch is electrically connected to the outdoor lighting assembly. The battery pack of the air pump assembly is powered by 3.6V. A charging port is also provided on the housing for external charging of the battery pack.
[0020] The beneficial effects of this invention are:
[0021] (1) The present invention uses the combination of knob and wire rope to make the hook swing and hook into the U-shaped groove of the anchor point, thereby reinforcing the handlebars and using double locking to ensure the stability of the air pump; at the same time, the knob-type second fixing component can be operated with one hand at any time if the air pump is found to be loose while riding, without reinforcing the first fixing component. The second fixing component can be reinforced again by simply rotating it, which greatly reduces the difficulty of operation while taking into account the need for accidental reinforcement.
[0022] (2) The present invention achieves dynamic double locking through the linkage design of the second fixing component and the limiting unit. A single rotation of the knob triggers two-stage action: the winding wheel tightens the steel wire rope to enhance the binding force of the handlebar, while the top of the annular groove pushes the rod to force the limiting block to radially clamp the rubber pad layer, thereby suppressing the risk of pad layer displacement caused by riding bumps from the root and solving the problem of pad layer slippage and structural loosening in traditional bolt fixing as much as possible.

[0031] 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.
[0032] Please see Figures 1-6 As shown, the present invention is a lithium-ion battery-powered air pump with lighting function, comprising: a housing 1, an air pump assembly 2 built into one side of the housing 1, an outdoor lighting assembly 3 integrated into the other side, a battery pack 4 disposed in the middle of the housing 1 for powering the air pump assembly 2 and the outdoor lighting assembly 3, and a handlebar fixing mechanism 5 disposed at the bottom of the housing 1 for fixing the air pump to the handlebar.
[0033] The handlebar fixing mechanism 5 includes:
[0034] The first fixing component 51 is used to initially fix the air pump to the handlebars;
[0035] The second fixing component 52 is used to reinforce the shell 1 after initial fixing and can be quickly loosened as needed.
[0036] The first fixing component 51 includes an adjustable arc-shaped clamp 511, which is adapted to handlebars of different diameters; a rubber pad layer 512 is filled on the inner side of the arc-shaped clamp 511 in contact with the handlebar.
[0037] The limiting unit 513 is used to limit the movement on both sides after the rubber pad layer 512 is filled.
[0038] The second fixing component 52 includes a knob 521, which is rotatably passed through the bottom of the housing 1 via an axial bearing. The knob 521 is exposed on the lower surface of the housing 1. The inner end of the knob 521 is coaxially fixed to a winding wheel 522. One end of the wire rope 528 is fixed to the winding groove 523 of the winding wheel 522, and the other end passes through the through hole in the side wall of the housing 1, the connecting ring 524 provided on the arc-shaped clamp 511, and then connects to the swingable hook 525.
[0039] When the knob 521 rotates in one direction, it drives the winding wheel 522 to wind and tighten the steel wire rope 528, causing the hook 525 to engage with the pre-set anchor point U-shaped groove 526 on the arc-shaped clamp 511. After the knob 521 is pulled outward, the ratchet fixed to the winding wheel 522 moves outward, thereby disengaging from the ratchet tooth 527 limit, releasing the ratchet tooth 527 lock inside the winding wheel 522, and rotating in the opposite direction to release the steel wire rope 528. An O-ring is nested at the center of the knob 521, and the winding wheel 522 is completely covered in the inner cavity of the waterproof cover integrally formed with the housing 1.
[0040] In this invention, the air pump assembly 2 and the outdoor lighting assembly 3 are integrated into the same housing 1, so that the air pump can be installed on the handlebars of the bicycle, which can simultaneously meet the needs of lighting and inflation, and occupy little space, thus improving the overall portability of the invention.
[0041] Meanwhile, in order to improve the connection between the air pump and the handlebars, a two-stage fixing unit is set up. The first fixing unit is fitted onto the handlebars by the arc-shaped clamp 511 at the bottom of the housing 1. Then, the rubber pad 512 is inserted into the arc-shaped clamp 511 and between it and the contact surface of the handlebars. Finally, bolts and nuts are inserted into the locking holes on the arc-shaped clamp 511 to tighten the arc-shaped clamp 511, thus achieving the initial fastening operation of the housing 1.
[0042] However, since bumpy roads are inevitable during riding, prolonged bumps can cause the bolt and nut structure to loosen, or the rubber pad 512 to deviate from the arc-shaped clamp 511 and the handlebar contact surface, causing the entire air pump to fall off.
[0043] Therefore, the present invention adds a second fixing component 52 and a limiting unit 513. The limiting unit 513 is used to limit the two sides of the filled rubber pad 512, thereby forcibly blocking the two sides of the rubber pad 512 and preventing the rubber pad 512 from running out of its original position after long-term bumping. On the one hand, the second fixing component 52, through the cooperation of the knob and the wire rope 528, causes the hook 525 to swing and hook into the anchor point U-shaped groove 526, forming a reinforcement effect on the handlebars, and using double locking to ensure the stability of the air pump. On the other hand, the knob 521 The second fixing component 52 can be operated with one hand at any time if the air pump is found to be loose or wobbly during riding, without needing to reinforce the first fixing component 51. Simply rotating the second fixing component 52 will reinforce it again, greatly reducing the difficulty of operation while also meeting the need for reinforcement in case of accidents. Furthermore, the knob 521 is exposed on the lower surface of the housing 1, with the operating surface facing down to prevent rainwater accumulation, while the winding wheel 522 is completely enclosed in the inner cavity of the waterproof cover, which can isolate it from the outside and prevent rainwater from entering and causing corrosion, thus extending its service life.
[0044] The exterior of the housing 1 is also provided with a rainproof mechanism 6, which is used to protect the exposed interfaces on the housing 1.
[0045] The rainproof mechanism 6 includes two parallel guide rails 61. The guide rails 61 are set at the exposed interface of the housing 1. A cover 62 is slidably connected to the guide rails 61. The outer surface of the cover 62 is provided with a protruding ridge 63. An iron ring 64 is provided at the exposed interface of the housing 1. A permanent magnet 65 is provided on the cover 62. The permanent magnet 65 cooperates with the iron ring 64 to form a magnetic attraction structure for the cover 62.
[0046] In this invention, a rainproof mechanism 6 is provided to prevent rainwater from entering the exposed interfaces during riding in the rain, thus preventing adverse effects. Specifically, when it is necessary to protect exposed interfaces on the housing 1, such as the charging port 10 and the air valve interface, the user pushes the cover 62 laterally along the parallel guide rail 61 on the surface of the housing 1. The cover engages with the guide rail 61 through the bottom groove and moves to completely cover the exposed interface. The permanent magnet 65 on the inner side of the cover 62 automatically attracts the iron ring 64 next to the interface, generating magnetic force to close it. The magnetic attraction makes the cover 62 fit tightly against the housing 1, forming a physical isolation layer to prevent rainwater from seeping into the interface and achieve the effect of maintaining a seal. When quickly releasing, the user's fingers hold the protrusion 63 on the surface of the cover 62 and apply force outward to overcome the magnetic attraction and slide laterally to expose the interface. The guide rail 61 limit design ensures that the sliding trajectory of the cover 62 is accurate and avoids falling off. Furthermore, the magnetic closure does not require a complicated lock; protection or release can be completed with a push and pull with one hand, and the permanent magnet 65 has no risk of rust in humid environments.
[0047] The limiting unit 513 includes two sets of limiting blocks 5131 that slide symmetrically on the inner side of the arc-shaped clamp 511, and a transmission unit that connects to the knob 521 in the second fixing component 52.
[0048] When the knob 521 is rotated, the transmission unit synchronously drives the two sets of limit blocks 5131 to move radially along the arc-shaped clamp 511, thereby achieving clamping and limiting or releasing the rubber pad layer 512 on both sides.
[0049] The transmission unit includes a push rod 5132. The bottom of the push rod 5132 is in contact with the top of the limiting block 5131. The top of the push rod 5132 is in contact with the bottom of the annular groove 5133. The annular groove 5133 is formed on the outer periphery of the winding wheel 522. The groove depth of the annular groove 5133 gradually decreases along the direction of twisting and tightening.
[0050] In this invention, the winding wheel 522 forms a motion coupling with the push rod 5132 through a gradually decreasing depth annular groove 5133 designed on its outer periphery, i.e., the groove depth decreases along the tightening direction of the knob 521; the top of the push rod 5132 is embedded in the annular groove 5133, and the bottom abuts against the limiting block 5131; when the user rotates the knob 521, the winding wheel 522 rotates synchronously, and the change in depth of the annular groove 5133 is directly converted into the linear displacement of the push rod 5132, driving the limiting block 5131 to perform clamping or releasing actions on the rubber pad layer 512; on the one hand, the linkage design of the second fixing component 52 and the limiting unit 513 achieves dynamic double locking, and the knob 521 rotates synchronously in one rotation. The system triggers two-stage actions: while the winding wheel 522 tightens the steel cable 528 to enhance the handlebar restraint, the annular groove 5133 pushes the push rod 5132, forcing the limiting block 5131 to radially clamp the rubber pad 512. This fundamentally suppresses the risk of pad displacement caused by riding bumps and solves the problem of pad slippage and structural loosening that often occur with traditional bolt fixing. On the other hand, if the air pump suddenly loosens during riding, the user does not need to operate the limiting unit 513; simply tightening the knob 521 with one hand will simultaneously complete the secondary tensioning of the steel cable 528 and the instantaneous locking of the rubber pad 512. The vertical movement mechanism of the push rod 5132 avoids oblique jamming and ensures a rapid reinforcement response. Through the above technical solution, the linkage mechanism, through the mechanical coupling of the annular groove 5133 of the winding wheel 522 and the push rod 5132, converts the rotation input of the knob 521 into the synchronous output of radial clamping force and axial tension force, breaking through the limitation of traditional two-stage fixing requiring step-by-step operation. The synergistic effect of the two can effectively eliminate the stress concentration caused by the micro-displacement of the rubber pad layer 512 during riding bumps, thus reducing the loosening rate of the bolts of the first fixing component 51.
[0051] The top of the housing 1 is equipped with a display screen 7, and an air pump switch 8 is provided on one side of the display screen 7. The air pump switch 8 is electrically connected to the air pump assembly 2. A lighting switch 9 is provided on one side of the housing 1. The lighting switch 9 is electrically connected to the outdoor lighting assembly 3. The battery pack 4 of the air pump assembly 2 is powered by a voltage of 3.6V. The housing 1 is also equipped with a charging port 10 for external charging of the battery pack 4.
