[0044] In daily life, car owners typically install tire locks on their vehicles to ensure safety, which is a basic requirement for vehicle security. However, besides safety issues, car owners may also encounter emergencies requiring temporary tire inflation, such as a punctured tire or insufficient air pressure. In such situations, car owners need an inflator to quickly inflate the tires to ensure the vehicle can continue driving or park safely.

[0045] However, most existing air inflators only have a single inflation function and do not take into account integration with vehicle safety features. This means that when car owners need to inflate their vehicles, they must not only carry the car lock to ensure vehicle safety, but also carry an additional air inflator, which increases the burden on users.

[0046] To address the above issues, please refer to the appendix to the instruction manual. Figure 1 The inflation device provided by this utility model integrates inflation and locking functions, eliminating the need to carry and store multiple devices, thus improving convenience.

[0047] In one embodiment, the inflation device provided by this utility model, such as Figures 1 to 3 As shown, it includes a housing 1, an air pump 4, and a locking assembly. The housing 1 has an air outlet 14 and an air inlet 13, wherein the air inlet 13 is used to receive external air, and the air outlet 14 is used to connect to an air inflator to inflate the tire.

[0048] Referring to the accompanying drawings, the housing 1 has a first part 101 and a second part 102 connected together, with a gap 15 formed between the two parts, so that the housing 1 forms a U-shaped profile. The gap 15 is used to connect the inflation device to the brake disc of the tire.

[0049] like Figure 3 and Figure 4 As shown, the air pump 4 is disposed within the first part 101 of the housing 1. The air pump 4 is connected to both the air outlet 14 and the air inlet 13, and is responsible for pumping gas from the air inlet 13 to the air outlet 14. Importantly, in this embodiment, the locking assembly is disposed in the first part 101 and the second part 102 of the housing 1. The user can operate the locking assembly to form a locking space together with the vacant part 15, thereby locking the inflation device to the tire brake disc.

[0050] Understandably, the first part 101 and the second part 102 are connected by a connecting segment. The position of the connecting segment corresponds to the empty part 15 of the housing 1. In use, the empty part 15 can be locked onto the edge of the brake disc, and the locking component can pass through the locking hole on the brake disc and lock it to use the inflation device as a vehicle lock.

[0051] In addition, the locking assembly can be designed as a two-way locking mechanism, in which the locking assemblies on the first part 101 and the second part 102 are capable of moving towards the hollow 15 at the same time, thereby locking the inflator device on the brake disc of the tire. This design means that the two locking assemblies move from opposite sides to the central hollow 15 until they contact or tightly grip each other, forming a stable locking structure.

[0052] Similarly, another embodiment is a one-way locking mechanism, in which only the locking assembly on the first part 101 or the second part 102 moves unidirectionally towards the hollow 15 to achieve locking of the inflator device. In this design, one locking assembly acts as a driving part, and the other acts as a driven part or a fixed part, ensuring that the device can be firmly locked on the brake disc.

[0053] Optionally, the specific implementation of the locking assembly can use extendable arms, hooks or clamps, which can be driven by mechanical structures such as elastic elements, gears or electric push rods.

[0054] Based on the above, as shown in the drawings, the outlet end 14 is connected to both the first part 101 and the second part 102, and the outlet end 14 penetrates the side wall of the second part 102, so that the inflator tube can be inserted into the second part 102 and connected to the output end of the inflator pump 4.

[0055] In this way, a stable plug-in fixation is provided, ensuring that the connection between the inflator tube and the outlet end 14 is firm, reducing the risk of gas leakage caused by unstable connection.

[0056] In a specific implementation, the outlet end 14 or the output end of the inflator pump 4 can be designed as an interface with internal threads to facilitate quick docking with an inflator tube with external threads. In order to enhance the stability of the connection, a locking ring or a snap ring can be provided inside the outlet end 14. When the inflator tube is inserted, the locking ring or the snap ring can automatically pop out and clamp the inflator tube, ensuring the firmness of the connection. At the same time, the side wall of the outlet end 14 is paved with a certain elastic material to provide a certain buffering and sealing effect.

[0057] In one embodiment, as shown in Figure 4 and Figure 6 , the housing 1 includes a first housing 11 and a second housing 12, and the hollow 15 is provided in the second housing 12, so that the second housing 12 has a U-shaped profile. The first housing 11 and the second housing 12 each have an opening facing the opposite direction, and the first housing 11 and the second housing 12 can be relatively engaged to form the overall structure of the housing 1. The operator can install the assembly inside the housing 1 through the opening, facilitating installation, disassembly and maintenance work.

[0058] Based on the present embodiment, the first part 101 is formed by the combination of the first shell 11 and the second shell 12, and the second part 102 corresponds to the structure of the second shell 12, which can be understood as the remaining structure of the second shell 12 except the part that combines with the first shell 11 to form the first part 101.

[0059] It can be understood that, since most of the components are arranged in the first part 101, the combination of the first shell 11 and the second shell 12 constitutes the main structure of the inflator. The second part 102 is mainly used to form the hollow part 15 and can cooperate with the locking assembly to realize the wheel locking function of the inflator.

[0060] In one embodiment, as shown in Figure 3 The locking assembly includes a power mechanism 23, a first locking end 21 and a second locking end 22. The first locking end 21 is arranged in the first part 101 of the shell 1, and the second locking end 22 is arranged in the second part 102 of the shell 1. The power mechanism 23 is responsible for adjusting the relative distance between the first locking end 21 and the second locking end 22 to realize the locking and unlocking of the device and the tire brake disc.

[0061] In the present embodiment, the positions of the first locking end 21 and the second locking end 22 are adjusted by the power mechanism 23, and the first locking end 21 or the second locking end 22 can be inserted into the locking hole of the brake disc to achieve stable locking. Optionally, the power mechanism 23 can be mechanical or electromagnetic to adapt to different application scenarios and needs. In the mechanical power mechanism 23, a gear and a rack can be used to cooperate, the rack is driven to move linearly by the rotation of the gear, thereby adjusting the position of the locking end. The mechanical power mechanism 23 can provide stable force transmission and precise position control. In the electromagnetic power mechanism 23, one of the locking ends can be telescopic, and the telescopic locking end can be controlled to extend or retract by the attraction or repulsion of the electromagnet, thereby realizing precise locking and unlocking.

[0062] Further, the power mechanism 23 is arranged in the first part 101 and cooperates with the first locking end 21. The power mechanism 23 can provide power to the first locking end 21 to move the first locking end 21 towards the second locking end 22 until the two ends are in abutment and locked, or vice versa, to move the first locking end 21 away from the second locking end 22 to realize unlocking.

[0063] In addition, the locking assembly can include a sensor, which can be integrated in the first locking end 21 or the second locking end 22 to monitor the contact state or locking force between the locking end and the brake disc. Specifically, the sensor can be a pressure sensor for detecting the pressure of the locking end on the brake disc to ensure that the locking force is within a safe range. In addition, the sensor can also be a position sensor for monitoring the position change of the locking end to ensure that the locking end is correctly abutted and locked.

[0064] In one embodiment, as shown in Figure 6 The first part 101 is provided with a mounting slot 30 extending from one side wall of the first part 101 away from the second part 102 to one side wall of the first part 101 facing the second part 102, providing a space for installing the first locking end 21 and the power mechanism 23, improving the space utilization to some extent, and helping to reduce the influence of the external environment on the power mechanism 23 and the locking end through the installation of the mounting slot 30, improving the reliability and durability of the device.

[0065] Based on the above, the second locking end 22 is provided as a locking hole, and the first locking end 21 has two end portions: one side end portion is a plug-in section 212, and the other side end portion is an operating end 211.

[0066] It should be noted that in the unlocked state, the plug-in section 212 of the first locking end 21 is located in the mounting slot 30, and the operating end 211 is flush with the slot side wall, facilitating storage and protection. When locked, the power mechanism 23 drives the first locking end 21 to move, and the plug-in section 212 is inserted into the locking hole of the second locking end 22 to achieve locking. When unlocked, the power mechanism 23 provides a reverse force to pull the first locking end 21 out of the locking hole and restore it to the unlocked position.

[0067] Further, as shown in Figure 4 and Figure 5 The power mechanism 23 includes a spring, which is sleeved on the outer periphery of the first locking end 21, providing the necessary power for the movement of the first locking end 21, so that the first locking end 21 can compress the spring under external force and move along a specific path in the mounting slot 30, realizing the docking with the locking hole of the second locking end 22, so that the inflator device can realize stable locking with the tire brake disc while inflating, improving the comprehensiveness of the inflator device application.

[0068] The mounting slot 30 includes a first limiting slot 301 and a second limiting slot 302, and the outer periphery of the first locking end 21 is provided with a limiting protrusion 213 matched with the limiting slot. The extension direction of the first limiting slot 301 is consistent with the extension direction of the mounting slot 30, and the extension direction of the second limiting slot 302 is perpendicular to the extension direction of the mounting slot 30, so that the first locking end 21 can produce horizontal movement and rotation.

[0069] In the first state, the limiting protrusion 213 is located in the first limiting groove 301, and the first locking end 21 can compress the spring and move a preset distance along the first limiting groove 301 under the action of an external force, so that the insertion section 212 of the first locking end 21 can be inserted into the locking hole of the second locking end 22, which can be understood as the first step of achieving locking. In the second state, the first locking end 21 can rotate under the action of an external force to rotate the limiting protrusion 213 into the second limiting groove 302. At this time, the limiting protrusion 213 is pressed tightly against the bottom wall of the second limiting groove 302 by the rebound force generated after being pressed by the spring, thereby locking the position of the first locking end 21, which can ensure that the first locking end 21 does not move accidentally in the locked state.

[0070] Wherein, there is a state transition between the first state and the second state, from the first state to the second state is the locking operation, that is, the operation when the car lock is locked. When unlocking, this process can be reversed, that is, first rotate the limiting protrusion 213 from the second limiting groove 302 back to the first limiting groove 301, so that the pressure of the spring can be released, and the first locking end 21 can return to its original position along the first limiting groove 301.

[0071] Optionally, the depth of the second limiting groove 302 can be set according to actual conditions, or a groove connected to the second limiting groove 302 can be provided, and the limiting protrusion 213 can be inserted into the groove when it moves to the second limiting groove 302, so as to increase the stability of the limiting protrusion 213 in the second limiting groove 302, prevent reverse rotation due to vibration or external force, and thus reduce the risk of accidental unlocking.

[0072] In one embodiment, as shown in Figure 3 and Figure 7 The inflation pump 4 includes a drive motor 41, an inflation cylinder 42, a piston 43, a valve 44, and a connecting rod 45. The core of the inflation pump 4 is the inflation cylinder 42 and the piston 43, which together form a reciprocating system. The piston 43 is arranged in the inflation cylinder 42 and can move reciprocally under the drive of the drive motor 41. One end of the connecting rod 45 is connected with the drive motor 41, and the other end is connected with the piston 43, ensuring that the rotary motion of the motor is converted into the linear reciprocating motion of the piston 43. The inside of the inflation cylinder 42 is connected with the gas outlet 14, so that the reciprocating motion of the piston 43 can pump gas from the valve 44 to the gas outlet 14.

[0073] Wherein, the valve 44 is connected with the inflation cylinder 42, and its main function is to control the one-way flow of gas, that is, to input gas into the inflation cylinder 42 when the piston 43 moves, and to prevent backflow of gas. The design of this one-way valve ensures that gas can only flow from the gas inlet 13 to the gas outlet 14, improving the inflation efficiency and preventing the loss of gas pressure.

[0074] Further, the inflator device further comprises a power supply module 5 and a circuit board 6. The circuit board 6 is arranged on the first part 101 away from the hollow part 15. More importantly, the plane of the circuit board 6 is parallel to the side wall of the shell 1, so that the circuit board 6 can be closely attached to the inside of the shell 1. In this way, the circuit board 6 does not occupy additional space inside the shell 1, thereby leaving more space for other key components such as the power supply module 5 and the drive motor 41.

[0075] The power supply module 5 is also arranged on the first part 101 of the shell 1 and is electrically connected to the circuit board 6 and the drive motor 41. In general, the power supply module 5 is a rechargeable battery, so that the inflator device is not only portable, but also can provide continuous power supply.

[0076] Referring to the accompanying drawings and in combination with the above, the first shell 11 and the second shell 12 each have two parallel cavities. When the first shell 11 and the second shell 12 are butted to form the first part 101, the corresponding cavities are butted to each other to form two independent areas, one for accommodating the locking assembly and the other for accommodating the power supply module 5 and the inflator pump 4, thereby improving the space utilization efficiency of the device and the rationality of the component layout, enhancing the stability of the device and the convenience of maintenance.

[0077] In one embodiment, the inflator device comprises a first partition 71 and a second partition 72 to optimize the component layout and improve the overall space utilization. The second partition 72 is connected to the inflator cylinder 42 and forms an integral whole, which not only ensures the stability of the structure, but also facilitates the integration of components.

[0078] Specifically, referring to the description and the accompanying drawings Figure 7 One end of the first partition 71 is butted to the circuit board 6, and the other end is connected to the second partition 72. The drive motor 41 is arranged in the mounting space formed by the first partition 71 and the second partition 72, and its output end penetrates the second partition 72 and is connected to the connecting rod 45 to realize power transmission.

[0079] The power supply module 5 is arranged on the side of the first partition 71 away from the drive motor 41, and is arranged in a staggered manner with the mounting space of the drive motor 41. Through the staggered design, the power supply module 5 and the mounting space of the drive motor 41 do not interfere with each other, thereby optimizing the space utilization.

[0080] In this embodiment, the connection between the partitions or the connection between the partitions and the circuit board 6 can be achieved by buckling, screwing or welding, etc. to ensure the firmness of the connection. Further, heat dissipation channels or cable channels can be provided on the first partition 71 or the second partition 72 to improve the performance and reliability of the device.

[0081] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered within the scope of the present application.
