[0001] This utility model relates to the field of bicycle air pumps, specifically to a solar-powered electric air pump. Background Technology

[0002] When riding in the wild, if you encounter a flat tire, you often choose to inflate it with an electric air pump.

[0003] However, existing electric air pumps have limited power and are easily depleted. When riding in the wild, the inability to replenish the power in time limits their use and fails to meet users' emergency outdoor needs. Utility Model Content

[0004] The purpose of this application is to solve the above problems and provide a solar-powered electric air pump that can be used to replenish electricity, has a wide range of applications, and meets the needs of users for outdoor emergency use.

[0005] To achieve the above objectives, this utility model provides a solar-powered electric air pump, comprising: a housing, a power module disposed within the housing, an inflation module disposed within the housing, a solar panel assembly detachably connected to the top surface of the housing, and a fixing module; the bottom of the housing has a limiting part that cooperates with a bicycle frame; the inflation module is electrically connected to the power module; the solar panel assembly includes at least one solar panel, which can be rotated to unfold to a horizontal position or retracted to at least one side of the housing, and the solar panel assembly is electrically connected to the power module; the fixing module fixes the limiting part to the bicycle frame.

[0006] Compared to existing technologies, the solar-powered electric air pump of this invention features a movable and adjustable solar panel that can be freely rotated, unfolded to a horizontal position to increase the power generation area, and folded into at least one side of the casing to reduce its size. Combined with a fixing module that allows for adjustable position, the installation location can be freely adjusted, enabling timely replenishment of electricity using solar energy, expanding the application range of the solar-powered electric air pump, and meeting users' outdoor emergency power needs.

[0007] In one embodiment, the solar panel assembly further includes a support portion, which is rotatably connected to the solar panel via a damping hinge. The support portion is detachably connected to the top surface of the housing. Through the support portion and the solar panel, the installation of the support portion is not affected when the solar panel is folded or closed, facilitating the rotational unfolding and folding of the solar panel.

[0008] In one embodiment, the solar panel assembly includes two solar panels, with each of the two solar panels rotatably connected to both sides of the support portion. By placing the solar panels on both sides of the support portion, the power generation area can be effectively expanded when the assembly is unfolded. When folded, the solar panels are symmetrically folded to the sides of the housing, stabilizing the center of gravity and ensuring the secure installation and fixation of the solar-powered electric air pump on the bicycle frame. It also allows for adjustment of the fixed position of the solar-powered electric air pump and the bicycle frame, ensuring the area above the solar panels is not obstructed or covered, and that the solar panels can still generate electricity from the side when folded, allowing the user to charge while riding. The unfolding angle of the solar panels can be adjusted to match complex external light conditions.

[0009] In one embodiment, a first mating part and a second mating part with complementary cross-sectional shapes are respectively provided at corresponding positions on the top surface of the housing and the solar panel assembly. The first mating part and the second mating part are slidably connected, and the solar panel assembly and the housing are disengaged by horizontally pulling the solar panel assembly or the housing. The complementary cross-sectional shapes of the first mating part and the second mating part form a mechanical interlock, allowing only horizontal pulling to slide relative to each other, thus achieving the effect of horizontally pulling the solar panel assembly and the housing to disengage.

[0010] In one embodiment, a buffer pad is provided on the side of the casing to support the solar panel. By providing the buffer pad, the solar panel contacts the buffer pad when it is retracted, which can reduce the scratches and wear between the solar panel and the side of the casing during riding, thereby improving stability.

[0011] In one embodiment, the power module includes a battery and a control component that controls the battery. The battery is electrically connected to the control component and to the solar panel assembly. Through the electrical connection between the battery and the control component, the control component controls the electrical energy of the battery, thereby controlling the inflation of the inflation module.

[0012] In one embodiment, the fixing module includes at least one knob, a first webbing, a second webbing, a buckle, and an elastic cord. The first webbing is disposed on a first side of the limiting portion, and the second webbing is disposed on a second side of the limiting portion opposite to the first side. The knob is disposed on the first webbing, and the buckle is disposed on the second webbing. The fixed end of the elastic cord is installed on the knob, and the movable end of the elastic cord is engaged with the buckle. The elastic cord is wound around the knob, and the knob can be rotated to tighten or loosen the elastic cord. A locking mechanism is provided inside the knob to prevent its rotation. Initial fixing is achieved by engaging the elastic cord, and then twisting the knob further secures the elastic cord and the webbing. Combined with the locking mechanism, this ensures a tight fixation between the solar-powered electric air pump and the bicycle frame. The knob and buckle are positioned opposite each other, with the knob on one side for easy one-handed operation, allowing the user to adjust the tension of the elastic cord while riding.

[0013] In one embodiment, the inflation module includes a drive mechanism, an air pump, an inflation hose, and a pressure sensor. The drive mechanism is electrically connected to the air pump, the air pump is connected to the inflation hose, the pressure sensor is mounted on the inflation hose, the pressure sensor is electrically connected to the control component, and the drive mechanism is electrically connected to the battery. By connecting the pressure sensor and the control component, the inflation module can be driven and controlled in real time, achieving the effect of automatically starting and stopping inflation, and preventing overcharging due to the user forgetting to turn it off.

[0014] In one embodiment, the side of the housing is provided with an inflation tube storage section for accommodating the inflation tube. By providing an inflation tube storage section on the side of the housing, it is convenient to store and retrieve the inflation tube, while not obstructing the solar panel from being retracted to at least one side of the housing. This ensures the retraction angle of the solar panel when the solar-powered electric air pump is retracted, thereby ensuring the stability of the solar panel when retracted and the overall stability of the solar-powered electric air pump fixed to the bicycle frame.

[0015] In one embodiment, the air tube receiving portion is a concave C-shaped groove.

[0023] like Figure 1-2 As shown, this application provides a solar-powered electric air pump. Specifically, the solar-powered electric air pump includes: a housing 110, a power module 120 disposed within the housing 110, an air inflation module 130 disposed within the housing 110, a solar panel assembly 140 detachably connected to the top surface of the housing 110, and a fixing module 150.

[0024] The bottom of the housing 110 is provided with a limiting part 111 that cooperates with the bicycle frame; the inflation module 130 is electrically connected to the power module 120; the solar panel assembly 140 includes at least one solar panel 142, which can be rotated to unfold to a horizontal position or folded into at least one side of the housing 110, and the solar panel assembly 140 is electrically connected to the power module 120; the fixing module 150 fixes the limiting part 111 to the bicycle frame.

[0025] When the solar panel 142 generates electricity, it transmits the electrical energy to the power module 120 for storage. When inflating the bicycle tire, the power module 120 is electrically connected to the inflation module 130, supplying power to the inflation module 130, which inflates the bicycle tire. The fixing module 150 secures and fastens the housing 110 and the bicycle frame.

[0026] The adjustable solar panel 142 can be freely rotated and unfolded to a horizontal position to increase the power generation area. It can also be folded up to at least one side of the housing 110 to reduce the volume. Together with the fixed module 150 that can adjust the position of the solar electric air pump, the installation position can be freely adjusted to realize the timely replenishment of electricity using solar energy, expand the application range of the solar electric air pump, and meet the user's outdoor emergency power needs.

[0027] The following is a detailed description of the specific structure of each component inside the solar-powered electric air pump.

[0028] The housing 110 is used to install and support the various components of the solar-powered electric air pump, and also provides a foundation for the installation of the solar-powered electric air pump and the bicycle frame.

[0029] like Figure 1 As shown, the bottom of the housing 110 has a limiting part 111 that mates with a bicycle frame. In this embodiment, the upper part of the housing 110 is shaped like a flat cube with a hollow interior, forming a cavity. A power module 120 and an inflation module 130 are installed inside the cavity. The top surface of the housing 110 has a first mating part 112 that is movably connected to the solar panel assembly 140.

[0030] The upper part of the housing 110 is designed as a flat cube. The bottom of the housing 110 has a limiting part 111 that cooperates with the bicycle frame, so that the solar electric air pump can be stably installed on the bicycle frame tube. The hollow interior of the housing 110 forms a cavity to accommodate the power module 120 and the air inflation module 130. The top surface of the housing 110 is provided with a sliding component that cooperates with the solar panel assembly 140, so that the solar panel assembly 140 can be detachably installed on the top surface of the housing 110.

[0031] The bottom of the housing 110 is provided with a limiting part 111 that mates with a bicycle frame. In one embodiment, the limiting part 111 is a concave arc surface adapted to the shape of the frame tube, and the width of the limiting part 111 can accommodate the width of the bicycle frame tube. In other embodiments, the limiting part 111 is a square groove that matches a square frame tube. The specific structure of the limiting part 111 can be designed according to actual needs. Furthermore, the limiting part 111 can also be provided with other auxiliary positioning structures, such as magnetic adsorption points or silicone pads on the concave arc surface of the limiting part 111, to improve the fit stability between the frame tube and the limiting part 111 and limit the movement of the housing 110 along the axial and circumferential surfaces of the frame tube. The structure and principle of the magnetic adsorption points and silicone pads are technologies known to those skilled in the art and will not be described in detail here.

[0032] In other embodiments, the specific structure of the housing 110 can be designed according to actual needs. It can be set with a streamlined shape. The housing 110 is perpendicular to the front end face of the frame tube and can adopt an appropriate amount of rounded corner design to reduce air resistance and increase installation stability. The structure and principle of the streamlined body and rounded corner are well known to those skilled in the art and will not be described in detail here.

[0033] like Figure 3 , Figure 6 As shown, in this embodiment, a first mating part 112 and a second mating part 1411 with complementary cross-sectional shapes are respectively provided at corresponding positions on the top surface of the housing 110 and the solar panel assembly 140. The first mating part 112 and the second mating part 1411 are slidably connected. By horizontally pulling the solar panel assembly 140 or the housing 110, the solar panel assembly 140 and the housing 110 can be disengaged. When the first mating part 112 and the second mating part 1411 are aligned and engaged in the horizontal direction, the solar panel assembly 140 and the housing 110 are in an installed state. When the first mating part 112 and the second mating part 1411 are separated, the solar panel assembly 140 and the housing 110 are in a disassembled state. The complementary cross-sectional shapes of the first mating part 112 and the second mating part 1411 form a mechanical interlock, allowing only horizontal pulling for relative sliding, achieving the effect of horizontally pulling outward to disengage the solar panel assembly 140 from the housing 110.

[0034] In other embodiments, the first mating portion 112 is disposed on both sides of the top surface of the housing 110 and is in the form of a boss. The second mating portion 1411, corresponding to the position of the first mating portion 112, is disposed on both sides of the bottom surface of the support portion 141 and is a groove corresponding to the boss. The boss and the groove are sized to correspond and their cross-sectional shapes are complementary. By horizontally pulling the housing 110 or the solar panel assembly 140, the boss and the groove move horizontally relative to each other, thereby realizing the movable connection between the housing 110 and the solar panel assembly 140.

[0035] In other embodiments, the solar panel assembly 140 is further provided with a release mechanism for disassembling the solar panel assembly 140. A corresponding structure is also provided on the top surface of the housing 110. The solar panel assembly 140 and the housing 110 can be disassembled and installed / locked together using a press-type snap-fit ​​mechanism. The structure and principle of the press-type snap-fit ​​mechanism are well-known to those skilled in the art and will not be described in detail here.

[0036] like Figure 5 As shown, in this embodiment, the side of the housing 110 is provided with an inflation tube storage portion 114 for storing the inflation tube 133. The inflation tube storage portion 114 is a concave C-shaped groove. When the inflation tube 133 is inflated, it is pulled out from the inflation tube storage portion 114 and connected to the valve of the bicycle tire to inflate the bicycle tire. When the inflation tube 133 is not inflated, it is stored in the inflation tube storage portion 114. By providing the inflation tube storage portion 114 on the side of the housing 110, it is convenient to store and retrieve the inflation tube, while not obstructing the solar panel 142 from being retracted to at least one side of the housing 110. This ensures the retraction angle of the solar panel 142 when the solar electric air pump is retracted, thereby ensuring the stability of the solar panel 142 when retracted and the overall stability of the solar electric air pump fixed to the bicycle frame.

[0037] like Figure 3 As shown, in this embodiment, a buffer pad 113 supporting the solar panel 142 is provided on the side of the housing 110. When the solar panel 142 is retracted to at least one side of the housing 110, the back of the solar panel 142 contacts the buffer pad 113, and the buffer pad 113 supports the solar panel 142. By providing the buffer pad 113, the solar panel 142 contacts the buffer pad 113 when retracted, which can reduce the scratching and wear between the solar panel 142 and the side of the housing 110 during riding, and improve stability.

[0038] like Figure 3As shown, in one embodiment, the housing 110 is further provided with control buttons 115 and a display screen 116. The control buttons 115 and display screen 116 are used for convenient user operation to control the mode of the solar-powered electric air pump. The control buttons 115 and display screen 116 are electrically connected to the power module 120. The control buttons 115 can be set to set the air pressure value, switch the battery 121 mode, and turn the solar-powered electric air pump on and off. The display screen 116 can display the air pressure mode and air pressure value. The control buttons 115 and display screen 116 facilitate user operation, allowing users to control the solar-powered electric air pump's on / off state, whether it is in mobile charging mode or inflation mode, and to set the inflation pressure.

[0039] like Figure 1 As shown, in one embodiment, a charging interface 117 is also provided on the housing 110. The charging interface 117 is electrically connected to the power module 120. The charging interface 117 is used to charge external devices. By providing the charging interface 117, the battery 121 can be switched to charging mode, and the solar-powered electric air pump can charge the user's mobile devices such as mobile phones, adapting to the user's outdoor cycling scenarios and meeting the user's emergency power needs.

[0040] The power module 120 is used to collect and store the electrical energy of the solar panel assembly 140, provide power to the inflation module 130, and control the inflation module 130 to inflate.

[0041] like Figure 7 As shown, in this embodiment, the power module 120 is arranged inside the housing 110. The power module 120 includes a battery 121 and a control component 122. The battery 121 is electrically connected to the control component 122 and the solar panel assembly 140. The battery 121 receives and stores the electrical energy transmitted from the solar panel assembly 140. The control component 122 is electrically connected to the battery 121 and controls the discharge of the battery 121. Through the electrical connection between the battery 121 and the control component 122, the control component 122 controls the electrical energy of the battery 121, thereby controlling the inflation of the inflation module 130. Through the connection between the battery 121 and the solar panel assembly 140, the electricity generated by the solar panel assembly 140 can be transmitted to the battery 121, achieving the goal of generating electricity using solar energy and collecting and storing the generated electricity.

[0042] The battery 121 is electrically connected to the solar panel assembly 140, as in one embodiment, such as Figure 3 As shown, a first magnetic connector 118 is provided on the top surface of the housing 110, and the first magnetic connector 118 is connected to the battery 121 via a wire. Figure 6As shown, a second magnetic connector 1412 is provided at a corresponding position on the solar panel assembly 140, and the second magnetic connector 1412 is connected to the solar panel via a wire. When the housing 110 is installed with the solar panel assembly 140, the first magnetic connector 118 at the corresponding position engages with the second magnetic connector 1412 to conduct electrical energy. The structure and principle of the magnetic connector are well known to those skilled in the art and will not be described in detail here.

[0043] The inflation module 130 is used to inflate bicycle tires.

[0044] like Figure 7 As shown, in this embodiment, the inflation module 130 is arranged inside the housing 110. The inflation module 130 is electrically connected to the power module 120. The inflation module 130 includes a drive mechanism 131, an air pump 132, an inflation tube 133, and a pressure sensor 134. The drive mechanism 131 is electrically connected to the air pump 132, and the air pump 132 is connected to the inflation tube 133. The pressure sensor 134 is installed on the inflation tube 133 and is electrically connected to the control component 122. The drive mechanism 131 is electrically connected to the battery 121. The control component 122 receives the signal from the pressure sensor 134 and controls the drive mechanism 131 according to the signal. The drive mechanism 131 drives the air pump 132 to inflate the bicycle tire. The gas flows from the air pump 132 to the inflation tube 133 and then to the bicycle tire. The pressure sensor 134 detects the pressure of the gas in the inflation tube. By connecting the air pressure sensor 134 and the control component 122, the inflation module 130 is driven and controlled in real time, so that the control component 122 drives the inflation module 130 to automatically start and stop inflation, and at the same time, it can also prevent the user from forgetting to turn it off and causing over-inflation.

[0045] In one embodiment, the inflation module 130 further includes a pressure cut-off mechanism 135. The pressure cut-off mechanism 135 receives a signal from the control component 122 and cuts off the air path of the inflation pump. The pressure cut-off mechanism 135 is disposed between the air pump 132 and the inflation pipe 133, and is signal-connected to the control component 122. The air pressure sensor 134 detects air pressure and transmits a signal to the control component 122. When the control component 122 detects that the air pressure has reached a set value, it sends a signal to the pressure cut-off mechanism 135, which then cuts off the air path and stops inflation. By setting the pressure cut-off mechanism 135 to cut off the air path in a timely manner, the over-inflation caused by the user forgetting to turn it off can be effectively prevented.

[0046] The solar panel assembly 140 is used to generate electricity for the power module 120, utilizing external sunlight to generate electricity.

[0047] In this embodiment, a solar panel assembly 140 is detachably connected to the top surface of the housing 110. The solar panel assembly 140 includes at least one solar panel 142. The solar panel 142 can be rotated to unfold to a horizontal position or folded into at least one side of the housing 110. The solar panel assembly 140 is electrically connected to the power module 120. By rotating and unfolding the solar panel 142 to a horizontal position, the unfolded area is increased, thereby improving power generation efficiency. By rotating and folding the solar panel 142 into at least one side of the housing 110, the overall volume is reduced, making it easier to carry while riding. It also allows for adjustment of the fixed position of the solar-powered electric air pump and the bicycle frame. The area above the solar panel 142 is not obstructed or covered, and the solar panel 142 can still generate electricity from the side when folded, allowing the user to charge while riding. The rotation adjustment of the unfolding angle of the solar panel 142 can be adjusted to match complex external light conditions.

[0048] In this embodiment, the solar panel assembly 140 further includes a support portion 141, which is rotatably connected to the solar panel via a damping hinge. The support portion 141 is detachably connected to the top surface of the housing 110. When the solar panel's hinge is extended, it extends to a horizontal position flush with the support portion 141; when the hinge is closed, it closes below the support portion 141, extending to at least one side of the housing 110. The support portion 141 and the solar panel 142 functionally divide the solar panel assembly 140. The closure of the solar panel 142 does not affect the installation of the support portion 141 or the housing, facilitating the rotational unfolding and closure of the solar panel 142.

[0049] In this embodiment, the solar panel assembly 140 includes two solar panels 142, and the two solar panels 142 are rotatably connected to both sides of the support portion 141. The presence of two solar panels 142 expands the power generation area when unfolded. When folded, the two solar panels 142 are respectively folded to both sides of the housing 110. This symmetrical arrangement stabilizes the center of gravity. By providing solar panels 142 on both sides of the support portion 141, the power generation area is effectively expanded when unfolded, and when folded, the solar panels 142 are symmetrically folded to both sides of the housing 110, stabilizing the center of gravity and ensuring the secure installation and fixation of the solar-powered electric air pump on the bicycle frame.

[0050] In other embodiments, the specific structure of the solar panel 142 can be designed according to actual needs. The length of the parallel side of the solar panel 142 can be set, requiring that the length of the parallel side closer to the user is greater than the length of the parallel side farther from the user, so as to reduce air resistance.

[0051] The fixing module 150 is used to fix the limiting part 111 to the bicycle frame and adjust the tightness of the fixation.

[0052] like Figure 4 As shown, in this embodiment, the fixing module 150 is used to fix the limiting part 111 to the bicycle frame. The fixing module 150 includes at least one knob 151, a first webbing 152, a second webbing 153, a buckle 154, and an elastic cord 155. The first webbing 152 is disposed on the first side of the limiting part 111, and the second webbing 153 is disposed on the second side of the limiting part 111 opposite to the first side. The knob 151 is disposed on the first webbing 152, and the buckle 154 is disposed on the second webbing 153. The fixed end of the elastic cord 155 is installed on the knob 151, and the movable end of the elastic cord 155 is engaged with the buckle 154. The elastic cord 155 is wound around the knob 151, and the knob 151 can be rotated to tighten or loosen the elastic cord 155. A locking mechanism is provided inside the knob 151 to prevent its rotation. When fixing the bicycle frame and the solar-powered electric air pump, the movable end of the elastic cord 155 is engaged with the buckle 154. Turning the knob 151 tightens the elastic cord 155, simultaneously tightening the first webbing 152 and the second webbing 153. This allows the fixing module 150 to tighten and fix the limiting part 111 and the bicycle frame from both sides. Simultaneously, the locking mechanism within the knob 151 ensures that the elastic cord 155 will not loosen under the tightening force. Initial fixing is achieved by engaging the elastic cord 155, and then turning the knob 151 further secures the elastic cord 155, the first webbing 152, and the second webbing 153, increasing the fixing area. Combined with the locking mechanism, this ensures a tight fixation between the solar-powered electric air pump and the bicycle frame. The knob 151 and the buckle 154 are arranged opposite each other. The knob 151 is located on one side, which is convenient for the user to operate with one hand and to adjust the tension of the elastic rope 155 with one hand while riding.

[0053] The knob 151 is equipped with a locking mechanism to prevent its rotation. In one embodiment, the locking mechanism may be a ratchet and pawl engagement structure. Twisting the knob 151 engages the ratchet and pawl, tightening the elastic rope 155. Stopping the knob 151 engages the pawl and ratchet, preventing the elastic rope 155 from automatically releasing under tension. Pulling the knob 151 upwards disengages the ratchet and pawl, and pulls the elastic rope 155 outwards, releasing it. The ratchet and pawl locking mechanism prevents the elastic rope 155 from being subjected to tension during riding, automatically releasing it and ensuring stable fixation. Operation is simple.

[0054] In summary, the solar-powered electric air pump provided by this utility model can be extended to a horizontal position or retracted to at least one side of the housing 110 by rotating the solar panel 142. This allows for expansion of the power generation area when extended and reduction of the volume when retracted. The angle of extension or retraction of the solar panel 142 can be freely adjusted. Therefore, it has the advantages of timely replenishment of electricity using solar energy, expanding the scope of use, and meeting the outdoor emergency power needs of users.
