[0001] This application relates to the field of power supply technology, and in particular to a multifunctional air pump device. Background Technology

[0002] With the development of automotive electronics technology, the demand for auxiliary equipment in daily vehicle use is increasing. For example, multi-functional air pumps generally have an emergency jump-start function, providing the power needed to start the vehicle. Furthermore, multi-functional air pumps are small, portable, and easy to operate, making them widely used in various emergency scenarios.

[0003] Existing multi-functional air pump devices typically include a housing, a battery assembly, and an electrode clamp assembly for connecting to an external battery. During use, the user must clamp the positive and negative terminals of the electrode clamp assembly to the corresponding terminals of the car battery to achieve power transfer.

This can affect the user's efficiency in subsequent use. Furthermore, carelessly placed electrode clip assemblies may suffer from wire wear and loosening of interfaces due to collisions or squeezing, which can affect the stability of electrical connections and even pose safety hazards.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." 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] With the development of automotive electronics technology, the demand for auxiliary equipment in daily vehicle use is increasing. Among them, the multi-functional air pump, as a common vehicle tool, is mainly used to provide the power needed to start the vehicle when the car battery is low. It has the advantages of small size, easy portability, and simple operation, and is widely used in various emergency scenarios.

[0039] Existing multi-functional air pump devices typically include a housing, a battery assembly, and an electrode clamp assembly for connecting to an external battery. During use, the user must clamp the positive and negative terminals of the electrode clamp assembly to the corresponding terminals of the car battery to achieve power transfer.

[0040] However, after use, electrode clip assemblies are often left lying around by users, which can easily lead to wire tangling or knotting when the assemblies are not in use. This can affect the user's efficiency in subsequent use. Furthermore, carelessly placed electrode clip assemblies may suffer from wire wear and loosening of interfaces due to collisions or squeezing, which can affect the stability of electrical connections and even pose safety hazards.

[0041] To address the technical problem of electrode clip assemblies being easily damaged when not in use in existing multi-functional air pump devices, this application provides a multi-functional air pump device that can store the used electrode clip assemblies in a specific storage structure, thereby effectively avoiding the problems of cable tangling and component scattering, thus improving the safety and reliability of the multi-functional air pump device, as well as enhancing the overall aesthetics and ease of operation of the multi-functional air pump device.

[0042] For details, please refer to [link / reference]. Figures 1-12 The multifunctional air pump device 10 provided in this application embodiment includes a housing assembly 100, a battery assembly 300, and an electrode clip assembly 520. The housing assembly 100 includes a top shell 110, a bottom shell 120, and a mounting shell 130. The mounting shell 130 is partially embedded in the top shell 110 and connected between the top shell 110 and the bottom shell 120. The mounting shell 130 has a mounting space 131 on the side facing the top shell 110, and the battery assembly 300 is disposed in the mounting space 131. The bottom shell 120 has a storage groove 511 on the side away from the top shell 110, and the electrode clip assembly 520 is located in the storage groove 511 and is electrically connected to the battery assembly 300.

[0043] Because the electrode clip assembly 520 is left lying around after use, it is easy for cables to become tangled, lost, or damaged, affecting user experience and equipment maintenance. Therefore, this embodiment provides a dedicated storage slot 511 on the electrode holder 510. After use, the user can remove the electrode clip assembly 520 from the car battery and place it in the storage slot 511, which avoids the problems of cable tangling and component scattering, and improves the overall aesthetics and user experience of the multi-functional air pump device 10.

[0044] See Figure 5 In some possible embodiments, the bottom shell 120 has a mounting hole 513 on the side away from the top shell 110, the mounting hole 513 penetrates the bottom shell 120, the electrode clip assembly 520 includes an electrode clip and a connecting wire connected together, the electrode clip is placed in the storage slot 511, and the connecting wire is connected to the battery assembly 300 through the mounting hole 513.

[0045] See Figures 5-6 In some possible implementations, the bottom shell 120 is further provided with a protective plug 600, which is embedded in the mounting hole 513. The protective plug 600 is provided with a through hole, through which the connecting wire passes and connects to the battery assembly 300.

[0046] The protective plug 600 can be made of soft rubber material. Because the soft rubber material makes the inner wall smooth and has a certain degree of elasticity, it can avoid damage such as scratches and cuts caused by metal or other hard edges to the cable during the installation of the connecting wire, thereby extending the service life of the connecting wire.

[0047] In addition, the protective plug 600 is tightly embedded in the mounting hole 513, which can prevent foreign objects from entering the mounting hole 513 and causing damage to the connecting wire, thereby improving the safety and durability of the multi-functional air pump device 10.

[0048] See Figures 5-6 In some possible implementations, the storage slot 511 is provided with a snap-fit ​​block 512, the electrode clip is provided with an opening 523, and when the electrode clip assembly 520 is placed in the storage slot 511, the opening 523 is clamped to the snap-fit ​​block 512.

[0049] By providing a snap-fit ​​block 512 in the storage slot 511 and clamping the opening 523 of the electrode clip to the snap-fit ​​block 512, the electrode clip can be securely stored in the storage slot 511 and will not easily fall off.

[0050] In some possible implementations, the snap-fit ​​block 512 is provided with a first limiting structure 51 and a second limiting structure 52, the first limiting structure 51 and the second limiting structure 52 being located on opposite sides of the snap-fit ​​block 512. When the electrode clip assembly 520 is placed in the receiving slot 511, the opening 523 is clamped in the snap-fit ​​block 512, and the first limiting structure 51 and the second limiting structure 52 abut against the electrode clip assembly 520.

[0051] By setting a first limiting structure 51 and a second limiting structure 52 on opposite sides of the snap-fit ​​block 512, bidirectional constraint and positioning of the electrode clip assembly 520 can be achieved, effectively preventing it from shifting, shaking or even falling off due to vibration, collision or external force in the storage state, thereby improving the stability and safety of the electrode clip assembly 520 in the storage process.

[0052] See Figure 2 , Figure 5 In some possible implementations, the first limiting structure 51 includes a limiting part 53 and a guide slope 54 connected to each other. When the electrode clip assembly 520 is placed in the storage groove 511, the limiting part 53 abuts against the electrode clip assembly 520 to prevent it from shifting or falling off due to vibration or external force, thereby improving the stability of the electrode clip assembly 520 in storage.

[0053] The guide ramp 54 is used to guide the electrode clip assembly 520 to be inserted along the radial direction of the snap-fit ​​block 512, reducing assembly difficulty and improving the convenience of user operation and storage efficiency.

[0054] In some possible implementations, the top of the snap-fit ​​block 512 is provided with a smooth transition structure 55.

[0055] Thus, by setting the top of the snap-fit ​​block 512 as a smooth transition structure 55, such as a rounded chamfer, the problem of missing corners caused by collisions during use due to sharp edges can be effectively avoided, thereby preventing the risk of the electrode clips becoming loose or falling off due to unstable support, and further improving the reliability and service life of the clamping connection.

[0056] In some possible implementations, the height of the snap-fit ​​block 512 is higher than the height of the electrode clip.

[0057] Thus, the higher locking block 512 provides more operating space, making it easier for users to apply force during clamping, thus improving the comfort and convenience of operation.

[0058] Furthermore, the height of the locking block 512 is greater than the height of the electrode clip, which increases the contact area and supporting force between the electrode clip and the locking block 512, thereby enhancing the overall stability of the clamping part. During use, especially under vibration or external force, the higher locking block 512 can better maintain the position of the electrode clip and reduce the risk of it loosening or falling off.

[0059] See Figure 5 In some possible implementations, the storage slot 511 is provided with a wire storage sub-slot 56, and when the electrode clip is placed in the storage slot 511, the connecting wire is at least partially located in the wire storage sub-slot 56.

[0060] By incorporating the wire storage slot 56, the connecting wires of the electrode clips can be neatly stored, preventing tangling, knotting, or damage caused by careless placement of the wires. This not only improves the overall compactness and aesthetics of the multi-functional air pump device 10 but also effectively enhances the stability and lifespan of the electrode clip assembly 520.

[0061] In addition, the wire storage slot 56 helps to realize the synchronous storage of the electrode clip and its connecting wire, preventing accidental short circuits or mechanical damage caused by exposed cables, and further enhancing the safety and reliability of the multi-functional air pump device 10.

[0062] See Figure 2 , Figure 6 , Figure 9 and Figure 11In some possible implementations, the electrode clip assembly 520 includes a positive electrode clip assembly 521 and a negative electrode clip assembly 522. The positive electrode clip assembly 521 includes a positive electrode clip 5211 and a positive electrode connecting wire 5212 connected together. The negative electrode clip assembly 522 includes a negative electrode clip 5221 and a negative electrode connecting wire 5222 connected together. The battery assembly 300 also includes a positive electrode connecting terminal 330 and a negative electrode connecting terminal 340. The positive electrode connecting wire 5212 is connected to the positive electrode connecting terminal 330. The multi-functional air pump device 10 also includes a circuit board 400. The circuit board 400 is provided with a first limiting groove 410 and a second limiting groove 420. The first limiting groove 410 and the second limiting groove 420 are arranged opposite to each other. The negative electrode connecting wire 5222 is located in the first limiting groove 410, and the negative electrode connecting terminal 340 is located in the second limiting groove 420. The negative electrode connecting wire 5222 is connected to the negative electrode connecting terminal 340.

[0063] Thus, by setting the first limiting groove 410 and the second limiting groove 420 on the circuit board 400, the negative connection wire 5222 and the negative connection terminal 340 can be effectively positioned and limited and fixed, preventing them from loosening or falling off due to external force or vibration, thereby improving the stability and reliability of the electrical connection and reducing the risk of damage caused by poor contact or line breakage.

[0064] In some possible implementations, the first limiting groove 410 and the second limiting groove 420 can be U-shaped limiting grooves.

[0065] By setting the first limiting groove 410 and the second limiting groove 420 as U-shaped limiting grooves, the friction between the negative terminal 340 and the negative connection line 5222 and the limiting groove can be reduced due to the smooth inner wall design of the U-shaped limiting groove, thereby improving the service life and safety of the negative terminal 340 and the negative connection line 5222.

[0066] See Figures 8-9 In some possible implementations, the circuit board 400 is further provided with a fixing through hole 430, which is used for the negative terminal 340 to pass through and connect to the negative connection line 5222.

[0067] Thus, by setting the fixed through hole 430, the user can pass the negative terminal 340 through the fixed through hole 430 and connect it to the negative terminal connection line 5222 of the negative terminal clip 5221, so as to further improve the stability of the negative terminal 340.

[0068] In addition, the fixed through hole 430 provides a flexible installation method: users can choose to fix the negative terminal 340 in the second limiting groove 420 or pass the negative terminal 340 through the fixed through hole 430 according to actual needs, thereby enhancing the adaptability and ease of operation of the multi-functional air pump device 10 in different application scenarios.

[0069] See Figures 8-9 In some possible implementations, the multi-functional air pump device also includes an air pump assembly 200 and an air pipe 210, wherein the air pipe 210 is provided with a first connecting end 211 and a second connecting end 212, the first connecting end 211 being connected to the air pump assembly 200, and the second connecting end 212 being used to connect to the vehicle to be inflated.

[0070] The air pump assembly 200 is electrically connected to the circuit board 400, which is mainly used to control and drive the start-up circuit of the emergency power supply and the operation of the air pump assembly 200.

[0071] For example, when a vehicle tire is leaking air or has insufficient pressure, the user can quickly inflate it using the air pump assembly 200 in the multi-functional air pump device to restore normal driving conditions. Specifically, the user can connect the second connection end 212 of the air hose 210 to the tire of the vehicle to be inflated. After receiving the user's start command, the circuit board 400 drives the air pump assembly 200 to start working, and the air hose 210 can then input the air generated by the air pump assembly 200 into the tire of the vehicle to be inflated, thereby inflating the vehicle.
