[0044] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.
[0045] In the field of modern transportation, tires as the key components directly contacting with the ground, their performance has a direct impact on the driving safety, stability and energy consumption of vehicles. Whether it is a car, an electric vehicle or a bicycle, tire pressure management is a basic requirement to maintain its performance. However, most of the existing inflation equipment has a single function, which is limited to inflating tires, and often has a large volume and is inconvenient to operate, making it difficult to meet the needs of rapid, convenient and multi-scenario use.
[0046] For example, in the use scenario of a bicycle, the rider often needs to carry an inflation device to deal with the situation of tire deflation. However, the existing inflation device is often separate from the device that locks the tire, causing the rider to carry multiple devices when traveling. This not only increases the burden of carrying, but also may cause inconvenience in emergency situations, affecting the safety and convenience of the rider. In addition, the design of the existing device often lacks intelligence and humanization, and cannot quickly adapt to the inflation needs of different tires, further reducing the use efficiency.
[0047] Based on the above problems, with reference to the description attached Figure 1 The inflation device provided by the utility model can inflate the tire, and also provides a locking function to adapt to different use scenarios and improve the safety of operation, solving the limitations of the prior art.
[0048] With reference to the description attached Figures 1 to 3 The inflation device provided by the utility model includes a shell 1, an inflation pump, an inflation pipe 3 and a locking assembly 4. The shell 1 is used to accommodate and protect the internal components, ensuring the durability and portability of the device. The inflation pump is installed in the shell 1, and the shell 1 is provided with an air inlet end 13 and an air outlet end 14. The inflation pump pumps gas, which can be transmitted from the air inlet end 13 to the air outlet end 14. The inflation pipe 3 has two ends, one end is fixed to the air outlet end 14, called the first end of the inflation pipe 3; the other end, which is away from the air outlet end 14, is called the second end of the inflation pipe 3. The second end of the inflation pipe 3 can be connected to the tire valve to directly inflate the tire.
[0049] The locking assembly 4 includes a matched first locking end 41 and a second locking end 42. The first locking end 41 is provided on the second end of the inflation pipe 3, and the second locking end 42 is provided in the shell 1. When the first locking end 41 and the second locking end 42 form a locking state, a closed locking space is formed between the inflation pipe 3 and the shell 1, which is not only used for locking the tire, but also facilitates the storage of the inflation pipe 3; when the two form an unlocked state, the second end of the inflation pipe 3 is in a free state and can be used for tire inflation.
[0050] The design of the inflator device in this embodiment has the advantages of integration and versatility. By integrating the inflator pump and the locking assembly 4 in a compact housing 1, the device is not only easy to carry, but also easy to operate. The design of the locking assembly 4 allows the inflator tube 3 to be safely stored when not in use, preventing loss or damage, and quickly unlocked for inflation when needed. In addition, the compact design of the device reduces the inconvenience of carrying multiple devices, making it particularly suitable for emergency use in vehicles such as bicycles, electric vehicles, and cars.
[0051] Alternatively, in this embodiment, the inflator tube 3 can be deformed under external force, allowing the inflator tube 3 to pass through the tire and be fixed around a specific part, such as temporarily fixing a bicycle to prevent it from moving. The second end of the inflator tube 3 can be passed through the tire and connected to a column on the side of the road or a fixed part of the bicycle body, such as a crossbar or other sturdy part, to achieve locking and stopping of the tire. When the tire needs to be inflated, operate the locking assembly 4 to separate the first locking end 41 from the second locking end 42, forming an unlocked state. At this time, the second end of the inflator tube 3 can be freely moved and connected to the tire valve for inflation.
[0052] It should be noted that the type and form of the locking assembly 4 in this embodiment are not limited, and the locking assembly 4 can be a mechanical lock, an electromagnetic lock, or any other suitable locking technology.
[0053] For example, in one implementation, a specific key can be used to lock or unlock, in which case the second locking end 42 is designed as a rotating component that cooperates with the first locking end 41 of the inflator tube 3 to achieve locking and unlocking of the inflator tube 3. When the inflator tube 3 needs to be locked to fix the tire, the user inserts the first locking end 41 of the inflator tube 3 into the second locking end 42 inside the housing 1, and inserts the mechanical key into the keyhole, rotates the key in the correct direction, so that the first locking end 41 engages with the second locking end 42, thereby locking the inflator tube 3. In the unlocking process, the user only needs to insert the mechanical key into the keyhole on the housing 1 and rotate it to the appropriate position to release the first locking end 41, allowing the second end of the inflator tube 3 to return to a free state for easy connection to the tire valve for inflation operation.
[0054] In addition, as mentioned above, the locking assembly 4 can be an electromagnetic lock, in which case an electromagnet unit can be integrated in the second locking end 42, which is designed to be docked with the first locking end 41 on the inflator tube 3. The first locking end 41 can be a magnet or a ferrous material. The power supply of the electromagnetic lock is provided by the power supply module 5 inside the inflator device, which can be a built-in rechargeable battery or an external power source. The power control unit is responsible for providing current to the electromagnet unit to generate a magnetic force. When the inflator tube 3 needs to be locked, the user only needs to activate the power control unit. The current passes through the coil of the electromagnet unit, generating a magnetic field that attracts the first locking end 41 of the inflator tube 3, achieving locking. When unlocking, the current supply is cut off, the magnetic field disappears, and the first locking end 41 is released, allowing the inflator tube 3 to move freely.
[0055] In one embodiment, the housing 1 is a hollow structure with a first chamber 110 and a second chamber 120 arranged side by side. The first chamber 110 is used to accommodate the inflator pump, while the second chamber 120 is used to accommodate the second locking end 42. This compartment design not only optimizes the use of internal space of the housing 1, but also enhances the structural stability and functionality of the device.
[0056] In addition, the housing 1 is provided with a jack 15 connected to the second chamber 120. Specifically, the jack 15 is aligned with the position of the second locking end 42, ensuring that the first locking end 41 can be smoothly and accurately inserted into the jack 15 and aligned with the second locking end 42, reducing the operation steps in the locking process, improving the efficiency and accuracy of the locking, and reducing the risk of locking failure due to improper operation.
[0057] In the embodiment, the size and shape of the jack 15 are accurately matched with the size and shape of the first locking end 41 and the second locking end 42. The position of the jack 15 is designed so that when the first locking end 41 is inserted, it can naturally align with the second locking end 42 without the need for additional adjustment.
[0058] Furthermore, based on the above, the jack 15 and the air outlet 14 are arranged on the same side wall of the housing 1, and the inflator tube 3 forms a U-shaped profile when locked, providing a compact and stable locking method.
[0059] At the same time, as shown, the inflator tube 3 can be wound along a predetermined path under the action of external force to form a reel structure. This winding mechanism allows the inflator tube 3 to be compactly stored when not in use, greatly reducing storage space and facilitating portability and storage. When needed, it can be quickly deployed. On the other hand, when the inflator tube 3 is wound into a reel structure, its stability and fixation effect are enhanced, allowing it to achieve a more intimate fit with the fixed part of the tire, providing better locking effect.
[0060] In practical applications, the inflatable tube 3 is usually made of high-strength flexible material to ensure that it can deform under external force while maintaining durability and reliability. The winding path and number of turns of the inflatable tube 3 can be adjusted according to actual application requirements to adapt to different use scenarios and storage needs.
[0061] In one embodiment, the locking assembly 4 includes a limiting structure arranged in the second chamber 120 adjacent to the insertion hole 15 to press and limit the first locking end 41 of the inflatable tube 3, preventing it from accidentally coming out of the insertion hole 15 during use.
[0062] Optionally, the limiting structure can take various mechanical forms, such as adjustable clamping devices or automatically expanding sealing rings, to adapt to different use requirements and operating environments. The specific design and material selection of the limiting structure are determined based on the size, working pressure, and use frequency of the inflatable tube 3 to ensure optimal limiting effect and durability.
[0063] In addition, based on the present embodiment, a sensing module such as a pressure sensor or a displacement sensor can be further arranged in the housing 1 to monitor the position and pressure state of the first locking end 41. Once an anomaly is detected, the system can automatically adjust the pressing force of the limiting structure or issue an alarm to the user.
[0064] In one embodiment, based on the above embodiment, as shown in Figures 4 to 6 The limiting structure includes at least two limiting blocks 43 and elastic members 44. The limiting blocks 43 are connected to the inner wall of the housing 1 through the elastic members 44, and the elastic members 44 are in a natural state when the first locking end 41 is not inserted into the insertion hole 15. When the first locking end 41 of the inflatable tube 3 is inserted into the insertion hole 15 and locked with the second locking end 42, the elastic members 44 generate a rebound force due to compression, which causes the limiting blocks 43 to move and press the peripheral wall of the first locking end 41, thereby achieving stable locking.
[0065] It can be understood that, in the present embodiment, an automatic adjustment pressing mechanism is provided by using the elastic members 44 and the limiting blocks 43, which not only simplifies the locking process but also enhances the reliability of the locking, ensuring that the first locking end 41 of the inflatable tube 3 can be stably locked in the preset position under various external forces.
[0066] In specific embodiments, the elastic members 44 can be springs, rubber pads, or other materials with elasticity, and it should be ensured that the elastic members 44 can generate sufficient rebound force after compression. The limiting blocks 43 can also be designed in different shapes, such as having protrusions or having recesses, to adapt to the shape of the peripheral wall of the first locking end 41 and achieve the best pressing effect.
[0067] Optionally, as shown in the figure, there are two limit blocks 43, so that the two limit blocks 43 can evenly press the first locking end 41 from opposite sides, ensuring the balance and reliability of the locking. Similarly, if there are more limit blocks 43, they can be evenly distributed around the first locking end 41 according to a certain pattern, which can more effectively prevent the rotation or movement of the first locking end 41 and provide a more stable locking effect.
[0068] In one embodiment, the limiting structure further includes a guide portion 45 and a notch portion 430. For details, please refer to the appendix to the specification. Figure 4 and Figure 5 A guide portion 45 is disposed within the second chamber 120 of the housing 1, while a vacancy portion 430 is disposed on the limiting block 43. The guide portion 45 engages with the vacancy portion 430 to guide the movement of the limiting block 43. This configuration ensures that the limiting block 43 can move precisely along a predetermined path when subjected to compression and rebound force, thereby effectively pressing against the peripheral wall of the first locking end 41 and enhancing the stability of the locking mechanism.
[0069] The cooperation between the guide part 45 and the empty part 430 not only provides precise guidance, but also ensures that the limit block 43 maintains the correct position and direction of movement during compression and rebound, preventing the limit block 43 from deviating or becoming unstable.
[0070] In some cases, multiple gaps 430 can be provided on a limit block 43, and correspondingly, multiple guides 45 are also provided on the inner wall of the housing 1, thereby forming a multi-point guiding mechanism, so that the limit block 43 can be subjected to force evenly, thereby reducing the stress concentration that a single contact point may bear, which helps to improve the durability and reliability of the limit structure; at the same time, this design also reduces the use of materials while maintaining structural strength, thus achieving weight reduction.
[0071] In this embodiment, the shape and size of the guide portion 45 and the empty portion 430 can be adjusted according to the specific design of the limiting block 43 and the elastic member 44 to ensure the best fit. For example, the guide portion 45 can be designed as a cylinder, a square or any other suitable shape to accommodate the corresponding empty portion 430.
[0072] In one embodiment, the limiting structure includes a limiting protrusion 431 and a limiting groove 46. Specifically, as shown... Figure 5 and Figure 6 As shown, the limiting protrusion 431 is disposed on the side of the limiting block 43 near the first locking end 41, while the limiting groove 46 is disposed along the circumference of the first locking end 41. When the limiting block 43 presses against the first locking end 41, the limiting protrusion 431 is inserted into the limiting groove 46, forming a double limiting.
[0073] It can be understood that the limiting protrusion 431, as an additional fixed point, cooperates with the limiting groove 46 to increase the mechanical locking, ensuring that the first locking end 41 of the inflation tube 3 will not be displaced or detached under high pressure or accidental external force.
[0074] As shown in some cases, the limiting block 43 at least partially extends to the second locking end 42. Specifically, when unlocking and inflating are needed, the user removes the locking state of the locking assembly 4 by a key or other unlocking mechanism. For example, by mechanical key unlocking, at this time the second locking end 42 rotates with the key, and the limiting block 43 on both sides is extruded outward, at this time the elastic member 44 moves and synchronously compresses to a certain extent, so that a gap is generated between the limiting block 43 and the first locking end 41, so that the first locking end 41 can be smoothly removed from the second locking end 42. Figure 5
[0075] In one embodiment, as shown, the inflator pump includes a drive motor 21, an inflation assembly 22. The inflation assembly 22 further includes an inflation cylinder 221, a piston 222, a valve and a connecting rod 223. Figure 2
[0076] The inflation cylinder 221 is the main space for gas compression and storage, and the piston 222 reciprocates in the cylinder to achieve gas compression; the valve is connected with the inflation cylinder 221, and is mainly used for controlling the one-way flow of gas, that is, when the piston 222 compresses the gas, the gas is input into the cylinder, and when the gas is output, the backflow of the gas is prevented; one end of the connecting rod 223 is connected with the drive motor 21, and the other end is connected with the piston 222, ensuring that the rotary motion of the motor is converted into the reciprocating linear motion of the piston 222. The inside of the inflation cylinder 221 is connected with the gas outlet end 14, so that the compressed gas can be smoothly pumped to the gas outlet end 14.
[0077] Further, as shown, the inflation assembly 22 further includes a matching piece 224 and a sliding block 225, the matching piece 224 is arranged between the drive motor 21 and the connecting rod 223, the drive shaft of the drive motor 21 is connected with the matching piece 224, and the matching piece 224 is connected with the connecting rod 223 through a rotating shaft. The sliding block 225 is arranged in the shell 1, and the surface thereof forms an inclined arc-shaped track, and the matching end of the connecting rod 223 is correspondingly arranged as a circular joint, which abuts against the surface of the sliding block 225; when the drive motor 21 operates, the matching piece 224 drives the connecting rod 223 to swing, the circular joint moves along the arc-shaped track on the surface of the sliding block 225, and then the linear motion of the piston 222 is realized. Figure 7
[0078] It should be noted that through the cooperation of the slider 225 and the arc-shaped track, the swinging motion of the connecting rod 223 is converted into the linear motion of the piston 222, so that the air pump can realize precise linear motion with less energy consumption, which is beneficial to improve the inflation efficiency and reduce mechanical wear.
[0079] In one embodiment, the charging device is provided with a power supply module 5 for supplying power to the air pump. In combination with the above-mentioned embodiment, in some cases, the power supply module 5 supplies power to the driving motor 21. Optionally, the power supply module 5 can be an internal rechargeable battery pack. The power supply module 5 is connected to the input end of the driving motor 21 through electrical connection, ensuring that the motor can obtain stable power supply during startup and operation.
[0080] It can be understood that the built-in power supply module 5 enables the inflation device to work independently without external power supply, greatly expanding its application range. In addition, the power supply module 5 can also integrate overload protection and short circuit protection functions to protect the driving motor 21 and the inflation assembly 22 from damage, thereby improving the reliability and safety of the entire device.
[0081] Based on the above, in some embodiments, the power supply module 5 can be designed as a portable lithium battery pack, which is charged through a USB-C or other charging interface; or the power supply module 5 can also include a smart management system for monitoring battery status, remaining capacity and charging cycle.
[0082] Further, the power supply module 5 can further integrate a solar charging panel, so that the inflation device can be charged under direct sunlight, increasing its practicality in emergency situations.
[0083] In one embodiment, the housing 1 of the charging device can be manufactured and assembled according to the description and drawings attached Figure 3 and Figure 8 The housing 1 of the charging device mainly includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 respectively have openings facing each other. The two openings are aligned when assembled, so that the two housings 1 can be fixedly connected to form a first cavity 110. In addition, a second cavity 120 is provided inside the second housing 12 to provide accommodation space for the locking assembly 4.
[0084] Among them, the first housing 11 and the second housing 12 can be independently manufactured and assembled, which is convenient for production and maintenance. The connection between the first housing 11 and the second housing 12 can be achieved by screwing, buckling or welding, etc., to ensure the firmness and sealing of the connection.
