Description

Technical Field

[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 during vehicle use is increasing. Currently, common car jump starters and electric air pumps are two frequently used vehicle tools, used to solve problems such as a dead car battery preventing the car from starting and a tire leak causing insufficient tire pressure, respectively.

[0003] Traditional emergency jump starters and electric air pumps are usually separate devices, which suffers from problems such as inconvenience in carrying, fragmented functions, and waste of resources, making it difficult to meet users' needs for multi-functional integrated products. To address these issues, existing technologies are beginning to explore integrating emergency jump starters and electric air pumps into a single device to achieve a compact structure and easy portability. These integrated products typically use a shared battery for power, with a circuit control module separately driving the emergency start circuit and the air pump motor, thus achieving the goal of multiple functions in one device.

[0004] However, in practical applications, the motor of an electric air pump is a moving part, which will generate vibration and impact during operation. This may cause collision and impact to the battery, which may easily lead to battery damage or even fire and other safety hazards. Since the batteries in existing products are mostly built-in designs with complex installation positions, the disassembly process requires disassembling a large number of structural components. Therefore, it is not possible to remove the battery in time to reduce the collision and impact on the battery. Utility Model Content

[0005] This application provides a multifunctional air pump device to solve the technical problem that the battery installation position in emergency start-up power supplies is relatively complex and the battery cannot be quickly removed.

[0006] In a first aspect, this application provides a multifunctional air pump device, which includes a housing, an air pump assembly, a battery assembly, a circuit board, and an electrode clip assembly. The housing includes a top shell, a bottom shell, and a mounting shell. The mounting shell is partially embedded in the top shell and connected between the top shell and the bottom shell. The mounting shell has a first side and a second side, which are arranged opposite to each other. The first side has an installation space, and the circuit board and the air pump assembly are located in the installation space. The air pump assembly is electrically connected to the circuit board. The second side has a battery receiving cavity, and the battery assembly is located in the battery receiving cavity and is detachably connected to the circuit board and the electrode clip assembly.

[0007] In some possible implementations, the battery assembly includes a battery body and a battery retainer, the battery body being located in the battery receiving cavity and detachably connected to the circuit board, and the battery retainer covering the battery body and detachably connected to the housing.

[0008] In some possible implementations, the battery retainer is snapped onto the housing.

[0009] In some possible implementations, the battery retainer is threaded to the housing.

[0010] In some possible implementations, the housing is provided with a plurality of threaded posts, which are spaced apart at the end of the battery receiving cavity, and the battery fixing member is provided with a plurality of threaded holes, each of which is connected to a corresponding threaded post in a one-to-one correspondence.

[0011] In some possible implementations, the battery housing cavity is provided with a wire through-hole, through which the battery assembly is connected to the electrode clip assembly.

[0012] In some possible implementations, the bottom shell is provided with a storage slot, the electrode clip assembly is disposed in the storage slot and detachably connected to the battery assembly, and the bottom shell is detachably connected to the housing.

[0013] In some possible implementations, the electrode clip assembly includes connected electrode clips and connecting wires, the storage slot is provided with a snap-fit ​​block and a mounting hole, the electrode clip is provided with an opening, the electrode clip is placed in the storage slot, the opening is clamped to the snap-fit ​​block, and the connecting wire is connected to the battery assembly through the mounting hole.

[0014] In some possible implementations, the electrode clip assembly includes a positive electrode clip assembly and a negative electrode clip assembly. The positive electrode clip assembly includes a positive electrode clip and a positive electrode connecting wire connected together. The negative electrode clip assembly includes a negative electrode clip and a negative electrode connecting wire connected together. The battery assembly further includes a positive electrode connecting terminal and a negative electrode connecting terminal. The positive electrode connecting wire is connected to the positive electrode connecting terminal.

The negative electrode connecting wire is located in the first limiting groove, and the negative electrode connecting terminal is located in the second limiting groove. The negative electrode connecting wire is connected to the negative electrode connecting terminal.

[0015] In some possible implementations, the circuit board is further provided with a fixing through hole for the negative terminal to pass through and connect to the negative connection line.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] Because this application places the battery assembly on one side of the mounting housing and isolates it spatially from other functional modules such as the air pump assembly and circuit board, compared to the traditional design where the battery is integrated inside the device and is difficult to disassemble, this application can improve the ease of disassembly and assembly of the battery assembly. Users can quickly replace or repair the battery assembly without disassembling the entire device body, thus improving the efficiency of battery assembly disassembly.

[0018] Furthermore, since the battery pack is independently mounted on one side of the mounting housing, the vibration and impact generated by the electric air pump mechanism during operation are effectively avoided from causing direct collisions to the battery pack. This reduces the safety hazards such as damage to the battery pack or even fire caused by mechanical impact, and further improves the overall safety and reliability of the multi-functional air pump equipment.

Detailed Implementation

[0040] 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.

[0041] 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.

[0042] 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.

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.

[0043] With the development of automotive electronics technology, the demand for auxiliary equipment during vehicle use is increasing. Currently, common car jump starters and electric air pumps are two frequently used vehicle tools, used to solve problems such as a dead car battery preventing the car from starting and a tire leak causing insufficient tire pressure, respectively.

[0044] Traditional emergency jump starters and electric air pumps are usually separate devices, which suffers from problems such as inconvenience in carrying, fragmented functions, and waste of resources, making it difficult to meet users' needs for multi-functional integrated products. To address these issues, existing technologies are beginning to explore integrating emergency jump starters and electric air pumps into a single device to achieve a compact structure and easy portability. These integrated products typically use a shared battery for power, with a circuit control module separately driving the emergency start circuit and the air pump motor, thus achieving the goal of multiple functions in one device.

[0045] However, in practical applications, the motor of an electric air pump is a moving part, which will generate vibration and impact during operation. This may cause collision and impact to the battery, which may easily lead to battery damage or even fire and other safety hazards. Since the batteries in existing products are mostly built-in designs with complex installation positions, the disassembly process requires disassembling a large number of structural components. Therefore, it is not possible to remove the battery in time to reduce the collision and impact on the battery.

[0046] To address the technical problem of complex battery installation locations in existing emergency start-up power supplies, which prevents quick battery removal, this application provides a multi-functional air pump device that improves the convenience of battery assembly and disassembly, thereby enabling rapid battery assembly removal.

[0047] See Figures 1-7 This application provides a multifunctional air pump device 10, which includes a housing 100, an air pump assembly 200, a battery assembly 300, a circuit board 400, and an electrode clip assembly 520. The housing 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 first side 111 and a second side 112, which are arranged opposite to each other. The first side 111 has a mounting space 131, and the circuit board 400 and the air pump assembly 200 are located in the mounting space 131. The air pump assembly 200 is electrically connected to the circuit board 400. The second side 112 has a battery receiving cavity 102, and the battery assembly 300 is located in the battery receiving cavity 102 and is detachably connected to the circuit board 400 and the electrode clip assembly 520.

[0048] This embodiment places the battery assembly 300 on one side of the mounting housing 130 and spatially isolates it from other functional modules such as the air pump assembly 200 and the circuit board 400. Compared with the traditional product design where the battery is integrated inside the device and is difficult to disassemble, this embodiment can improve the ease of disassembly and assembly of the battery assembly 300. Users can quickly replace or repair the battery assembly 300 without disassembling the entire device body, thus improving the efficiency of disassembly of the battery assembly 300.

[0049] Furthermore, since the battery component 300 is independently located on one side of the mounting housing 130, the vibration and impact generated by the electric air pump core during operation are effectively avoided from causing direct collision with the battery component 300. This reduces the safety hazards such as damage to the battery component 300 or even fire caused by mechanical impact, and further improves the overall safety and reliability of the multi-functional air pump device 10.

[0050] The air pump assembly 200 includes components such as an air pump and a motor. The motor, as a driving component, is connected to the air pump and electrically connected to the battery body 310. It receives electrical energy from the battery assembly 300 and converts the electrical energy into mechanical energy to power the air pump, thereby driving it to complete the inflation function.

[0051] The multi-functional air pump device also includes an air pipe 210 and a fan, wherein the fan is located near the air inlet and connected to the air inlet end of the air pump assembly 200, and the air outlet end of the air pump assembly 200 is located near the air outlet and connected to the air inlet end of the air pipe 210.

[0052] In this way, outside air can enter the housing 130 through the air inlet and flow to the fan. The fan guides the air to the air pump assembly 200 for compression. Then, the compressed gas is output through the air pipe 210 to the air outlet connector of the air pipe 210 and finally delivered to the tires of the vehicle to inflate the tires.

[0053] In some possible implementations, the battery assembly 300 includes a battery body 310 and a battery retainer 320. The battery body 310 is located in the battery receiving cavity 102 and is detachably connected to the circuit board 400. The battery retainer 320 covers the battery body 310 and is detachably connected to the mounting housing 130.

[0054] Among them, the battery fixing component 320 can be a battery cover.

[0055] By providing a battery retainer 320 on the battery body 310 that is detachably connected to the mounting shell 130, the user can easily remove the battery body 310 simply by removing the battery retainer 320.

[0056] In some possible implementations, the battery retainer 320 is snapped onto the mounting housing 130.

[0057] For example, the mounting housing 130 may be provided with at least one elastic buckle protrusion or slot, and the battery fixing component 320 is provided with a matching groove or hook at the corresponding position. The two cooperate with each other to achieve quick installation and disassembly.

[0058] When the user aligns the battery retainer 320 with the mounting position on the mounting housing 130 and applies pressure, the latching structure automatically locks, firmly fixing the battery retainer 320 to the mounting housing 130. When disassembly is required, simply press or move the latching part to release the locking state, enabling tool-free quick disassembly and assembly.

[0059] In some possible implementations, the battery holder 320 is threaded to the mounting housing 130.

[0060] See Figures 6-7 In some possible implementations, the mounting housing 130 is provided with a plurality of threaded posts 113, which are spaced apart at the end of the battery receiving cavity 102. The battery fixing member 320 is provided with a plurality of threaded holes 321, each of which is connected to a corresponding threaded post 113 in a one-to-one correspondence.

[0061] The user can improve the stability of the connection between the battery holder 320 and the mounting housing 130 by aligning the threaded hole 321 of the battery holder 320 with the threaded post 113 on the mounting housing 130 and tightening the screw. When disassembly is required, the connection can be loosened by simply rotating the screw in the opposite direction, thus completing the disassembly operation of the battery holder 320.

[0062] In some possible implementations, the battery holder 320 can be connected to the mounting housing 130 by both threaded connection and snap-fit ​​connection, which can further improve the stability of the connection of the battery holder 320.

[0063] In some possible implementations, the battery housing 102 is provided with a wire through-hole 103, through which the battery assembly 300 is connected to the electrode clip assembly 520.

[0064] See Figures 8-12 In some possible implementations, the battery body 310 may be provided with some connecting wires, such as motor connecting wires and air pump connecting wires. One end of these connecting wires can be soldered to the battery body 310 through the wire through hole 103, and the other end can be detachably connected to the circuit board 400. In this way, the battery body 310 can achieve electrical connection with the motor, air pump and other equipment through the connecting wires connected to the circuit board 400.

[0065] In some possible implementations, the battery body 310 can be connected to the circuit board 400 via a connector 800. Exemplarily, the connector 800 may include a first sub-connector 810 and a second sub-connector 820.

[0066] The first sub-connector 810 includes a first connector 811 and a first wire connection end 812. The second sub-connector 820 includes a second connector 821 and a second wire connection end 822. The first wire connection end 812 is detachably connected to the battery body 310, the second wire connection end 822 is detachably connected to the circuit board 400, and the first connector 811 is detachably connected to the second connector 821.

[0067] The second wire connection end 822 includes a motor connection wire and an air pump connection wire, which are connected to the circuit board 400. Based on this, the battery body 310 can be electrically connected to the motor and the air pump through the connector 800.

[0068] In some possible implementations, the electrode clip assembly 520 includes a bottom shell 510 and an electrode clip assembly 520. The bottom shell 510 is provided with a storage groove 511. The electrode clip assembly 520 is disposed in the storage groove 511 and is detachably connected to the battery assembly 300. The bottom shell 510 is detachably connected to the mounting shell 130.

[0069] The battery body 310 can be disassembled by removing the electrode clip assembly 520 from the mounting housing 130 and then removing the battery retainer 320. This improves the ease of disassembling the battery assembly 300.

[0070] Furthermore, since the electrode clip assembly 520 is often left lying around after use, it can easily lead to cable tangling, loss, or damage, affecting user experience and equipment maintenance. Therefore, this embodiment provides a dedicated storage slot 511 on the bottom shell 510. After use, the user can remove the electrode clip assembly 520 from the car battery and place it in the storage slot 511, avoiding cable tangling and component scattering, thus improving the overall aesthetics and user experience of the multi-functional air pump device 10.

[0071] In some possible implementations, the electrode clip assembly 520 includes connected electrode clips and connecting wires, the storage slot 511 is provided with a snap-fit ​​block 512 and a mounting hole 513, the electrode clip is provided with an opening 523, the electrode clip is placed in the storage slot 511, the opening 523 is clamped to the snap-fit ​​block 512, and the connecting wire is connected to the battery assembly 300 through the mounting hole 513.

[0072] 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.

[0073] See Figures 13-16In 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 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.

[0074] 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.

[0075] In some possible implementations, the first limiting groove 410 and the second limiting groove 420 can be U-shaped limiting grooves.

[0076] 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.

[0077] In some possible implementations, the circuit board 400 is further provided with a fixing through hole 430 for the negative terminal 340 to pass through and connect to the negative connection line 5222.

[0078] 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.

[0079] 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.
