[0035] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] In the description of the embodiments of the present application, it should be noted that the terms "upper," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0038] As a product that can output electrical energy, the power supply device can usually be used to power an air pump or an emergency starting power supply, thereby achieving the function of inflation or assisting the emergency starting of the vehicle.

[0039] In the related art, the electrical connection between the host and the power supply component inside the power supply device is generally achieved through a spring clip or spring pin connector, and the electrical connection between the host and the power supply component is prone to disconnection and instability.

[0040] Based on the above situation, the present application embodiment provides a power supply device 10, please refer to Figures 1 to 7. The power supply device 10 includes a host 11, a power supply assembly 12 and a connector 13. The power supply assembly 12 is detachably docked with the host 11 along a first direction, and is used to provide power to the host 11 or an external device. The host 11 includes a shell assembly 111. The shell assembly 111 has a accommodating cavity 111a and a first opening 111b. The power supply assembly 12 extends into the accommodating cavity 111a through the first opening 111b. The connector 13 includes a first connecting portion 131 and a second connecting portion 132, which are separately arranged. The first connecting portion 131 is arranged on a side of the power supply assembly 12 away from the first opening 111b. The second connecting portion 132 is arranged on the host 11. One of the first connecting portion 131 and the second connecting portion 132 is formed with a slot 1312a, and the other is formed with a plug 1321. The plug 1321 can be inserted into the slot 1312a along the first direction toward the first opening 111b to achieve electrical connection between the host 11 and the power supply assembly 12.

[0041] Exemplarily, the power supply component 12 is an independent replaceable module, that is, the power supply component 12 is connected to the host 11 as an independent functional module. The power supply component 12 is manufactured separately from the host 11. The power supply component 12 can independently perform its functions, such as providing power to external devices (such as electronic devices), and can also cooperate with the host 11 to realize the corresponding functions of the power supply device 10, and can also provide power for the power supply component 12 itself.

[0042] Specifically, on the one hand, the power supply assembly 12 can be removed from the main unit 11 and used independently as a mobile power source to charge electronic devices, thereby realizing its function of powering external devices; it can also provide power to its own internal electrical components (such as lights) to realize functions such as lighting. On the other hand, the power supply assembly 12 can be integrated with the main unit 11 of the power supply device 10 to power the main unit 11, thereby realizing the corresponding functions of the main unit 11.

[0043] For example, the function of the host 11 can be to inflate, to perform emergency starting of the vehicle, or a combination of the two, that is, the host 11 can be combined with one or both of the air pump assembly 20 of the air pump and the starting power module of the emergency starting power supply. The power supply assembly 12 supplies power to the air pump assembly 20 and / or the starting power module by supplying power to the host 11, thereby realizing the power supply device 10 as a whole to the air pump and the emergency starting power supply. Of course, the host 11 can also realize other functions, which are not limited here.

[0044] In addition, the detachable connection method can also facilitate the replacement of the power supply component 12 and ensure the power supply reliability of the power supply device 10.

[0045] The first direction may be any direction. For example, the first direction may be the length direction of the host 11 and be perpendicular to the thickness direction of the host 11 .

[0046] It should be noted that the dimensions of different components in the three directions in the same absolute coordinate system are different. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0047] In the embodiment of the present application, the length direction and thickness direction of the host 11, the power supply assembly 12 and the power supply device 10 are consistent.

[0048] The shell assembly 111 has a accommodating cavity 111a and a first opening 111b, wherein the accommodating cavity 111a is connected to the first opening 111b, and the first opening 111b is set at one end of the shell assembly 111 along the first direction. The accommodating cavity 111a extends along the first direction, so that the power supply assembly 12 can extend into the accommodating cavity 111a through the first opening 111b.

[0049] In the embodiment of the present application, the cavity wall of the accommodating cavity 111a can be wrapped around the outer periphery of the power supply assembly 12, that is, the cavity wall of the accommodating cavity 111a is wrapped around the outer side of the peripheral side wall of the power supply assembly 12. The wrapping here does not affect the corresponding functional operation of the power supply assembly 12, for example, it does not affect the key function of the power supply assembly 12. In this way, the accommodating cavity 111a will roughly surround the outer periphery of the power supply assembly 12 to form a fully enclosed structure. The accommodating cavity 111a is formed into a through-groove structure or a blind-groove structure. The two ends of the through-groove structure are open along the first direction and connected to the first opening 111b. The side of the blind-groove structure close to the first opening 111b is open and connected to the first opening 111b, and the side away from the first opening 111b is closed. Of course, the accommodating cavity 111a can also form a semi-enclosed structure, that is, part of the structure of the power supply assembly 12 is arranged outside the accommodating cavity 111a and is not wrapped by the accommodating cavity 111a.

[0050] For example, the projection of the power supply assembly 12 on a plane perpendicular to the first direction does not exceed the projection range of the housing assembly 111 on a plane perpendicular to the first direction. In this way, the power supply device 10 has a more beautiful appearance, a more compact overall structure, and a more reliable fixation of the power supply assembly 12 to the host 11.

[0051] The first connection part 131 and the second connection part 132 are separately arranged, which means that the first connection part 131 and the second connection part 132 are manufactured and formed separately. The first connection part 131 is arranged on the side of the power supply component 12 away from the first opening 111b, and the second connection part 132 is arranged on the host 11. When the first connection part 131 and the second connection part 132 are docked, the electrical connection between the power supply component 12 and the host 11 can be achieved.

[0052] One of the first connection portion 131 and the second connection portion 132 is formed with a slot 1312a, and the other is formed with a plug 1321, which means that the positions of the slot 1312a and the plug 1321 can be interchanged. For example, in some embodiments, the slot 1312a is formed on the second connection portion 132, and the plug 1321 is formed on the first connection portion, that is, the slot 1312a is set on the host 11, and the plug 1321 is set on the power supply component 12; in other embodiments, the slot 1312a is formed on the first connection portion 131, and the plug 1321 is formed on the second connection portion 132, that is, the slot 1312a is set on the power supply component 12, and the plug 1321 is set on the host 11.

[0053] In the embodiment of the present application, the connector 13 may be a blade connector.

[0054] Compared with the spring pieces or spring pins used in the related art, the connection between the insert piece 1321 and the slot 1312a in the embodiment of the present application is more stable and reliable, thereby improving durability and safety.

[0055] For example, in the case where slot 1312a is formed on first connection portion 131 and tab 1321 is formed on second connection portion 132, first connection portion 131 is formed with slot 1312a and disposed on power supply assembly 12, thereby providing a stable position for insertion of second connection portion 132. Second connection portion 132 is formed with tab 1321 and disposed on host 11, thereby providing a stable fixed position for tab 1321. Thus, on the one hand, host 11 provides protection for tab 1321, reducing the chance of tab 1321 rubbing against external structures, thereby improving the reliability and safety of connector 13. On the other hand, the placement of tab 1321 on host 11 facilitates the arrangement of slot 1312a, making the size of power supply assembly 12 more appropriate, thereby reducing the size of accommodating cavity 111a, thereby increasing the structural compactness of power supply device 10 and reducing the overall size of power supply device 10.

[0056] For example, in an embodiment where the slot 1312a is formed in the first connection portion 131 and the plug 1321 is formed in the second connection portion 132, at least a portion of the plug 1321 may protrude from the side wall of the accommodating cavity 111a. Here, the plug 1321 may or may not be in contact with the side wall of the accommodating cavity 111a, as long as it protrudes toward the power supply component 12.

[0057] The plug 1321 can be inserted into the slot 1312a along the first direction toward the first opening 111b. At the same time, the first connecting portion 131 is arranged on the side of the power supply component 12 away from the first opening 111b. In the process of the power supply component 12 extending into the accommodating cavity 111a through the first opening 111b, the opening of the slot 1312a is at least along the first direction toward the plug 1321, so that the plug 1321 can be inserted into the slot 1312a along the first direction. In this way, during the insertion process of the power supply component 12, when the slot 1312a contacts the plug 1321, the plug 1321 can be directly inserted into the slot 1312a along the first direction, which facilitates docking and reduces the probability of contact wear between the slot 1312a and the plug 1321, thereby improving the reliability of the electrical connection between the host 11 and the power supply component 12.

[0058] The power supply device 10 provided in the embodiment of the present application, on the one hand, realizes that the power supply component 12 can be used alone as a mobile power supply, and can be combined with the host 11 to power the host 11 to realize the functions of the host 11 by detachably docking the power supply component 12 with the host 11 along the first direction. On the other hand, by setting the first connecting part 131 on the side of the power supply component 12 away from the first opening 111b, and setting the second connecting part 132 on the host 11, the notch of the slot 1312a is at least along the first direction toward the plug 1321, so that the plug 1321 can be inserted into the slot 1312a along the first direction. In this way, during the insertion process of the power supply component 12, when the slot 1312a contacts the plug 1321, the plug 1321 can be directly inserted into the slot 1312a along the first direction. The docking is simple and convenient, and the chance of damage to the plug 1321 or the slot 1312a can be reduced. The connection between the plug 1321 and the slot 1312a makes the electrical connection between the power supply component 12 and the host 11 more stable and reliable, thereby improving the durability and safety of the electrical connection structure.

[0059] For some examples, see Figures 3 to 7 There are multiple slots 1312a and inserts 1321 in a one-to-one correspondence. The multiple slots 1312a are arranged along the second direction and are not interconnected. The multiple inserts 1321 extend along the third direction and are spaced apart along the second direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0060] It should be noted that the multiple mentioned in the embodiments of the present application refers to a number of two or more.

[0061] There are multiple slots 1312 a and multiple inserting pieces 1321 in a one-to-one correspondence, which means that the number of slots 1312 a and the number of inserting pieces 1321 are the same.

[0062] Exemplarily, the number of the slots 1312a and the number of the inserts 1321 are both five.

[0063] The plurality of slots 1312a are arranged along the second direction and are not interconnected, that is, the slots 1312a are isolated from each other, so that there is no cross-current between the slots 1312a, thereby improving the stability and reliability of current transmission.

[0064] The second direction can be parallel to the thickness direction of the main unit 11, that is, the arrangement direction of the slot 1312a is the same as the arrangement direction of the plug 1321, both along the thickness direction of the main unit 11, so that when the power supply component 12 extends into the accommodating cavity 111a through the first opening 111b, the plug 1321 can be inserted into the slot 1312a more smoothly along the first direction, that is, perpendicular to the thickness direction.

[0065] Exemplarily, the third direction is the width direction of the host 11 .

[0066] Exemplarily, the slot 1312a has a first slot and a second slot that are interconnected, the first slot facing the side away from the first opening 111b along the first direction, and the second slot facing the side away from the power supply assembly 12 along the third direction, so that when the power supply assembly 12 is extended into the accommodating cavity 111a, the plug 1321 extending along the third direction can directly extend into the slot 1312a.

[0067] For some examples, see Figures 3 to 7 The connector 13 includes an elastic structure 1311. The elastic structure 1311 is disposed in the slot 1312a and is configured to apply a force in a second direction to the inserting piece 1321 inserted into the slot 1312a, thereby locking the inserting piece 1321 in the slot 1312a. The second direction is perpendicular to the first direction.

[0068] It should be noted that there are multiple elastic structures 1311 and they correspond one-to-one to the slots 1312 a , that is, one elastic structure 1311 is disposed in each slot 1312 a .

[0069] Exemplarily, the insert 1321 extends along the third direction, and the elastic structure 1311 can apply a force to the insert 1321 along the second direction, thereby limiting the insert 1321 along the second direction, increasing the stability of the insert 1321 in the slot 1312a, and reducing the chance of the insert 1321 moving or shaking or even falling out of the slot 1312a.

[0070] The specific structure of the elastic structure 1311 is not limited.

[0071] For some examples, see Figures 5 to 7The elastic structure 1311 includes at least two elastic pieces 1311a. The two ends of the portion of the inserting piece 1321 inserted into the slot 1312a along the second direction are sandwiched between the two elastic pieces 1311a.

[0072] The elastic structure 1311 includes at least two elastic sheets 1311a. The elastic structure 1311 may also include a connecting sheet for connecting the two elastic sheets 1311a. The connecting sheet combines the current of the two elastic sheets 1311a into one or divides it into two, and is electrically connected to the plug 1321 clamped by the elastic structure 1311.

[0073] The portion of the inserting piece 1321 inserted into the slot 1312a is sandwiched between two elastic pieces 1311a at both ends along the second direction. That is, the two elastic pieces 1311a can exert forces on the inserting piece 1321 in opposite directions, thereby stabilizing the position of the inserting piece 1321 in the slot 1312a.

[0074] Specifically, during the process of inserting the plug 1321 into the slot 1312a, the plug 1321 applies a force to the spring pieces 1311a on both sides, so that the spring pieces 1311a abut against the slot walls of the corresponding slot 1312a. After the plug 1321 is completely inserted into the slot 1312a, the spring pieces 1311a on both sides apply forces in opposite directions to the middle plug 1321, so that the plug 1321 is stably set in the slot 1312a under the action of elastic force, reducing the probability of the plug 1321 falling off from the slot 1312a, thereby increasing the electrical connection stability between the host 11 and the power supply component 12.

[0075] For some examples, see Figures 3 to 7 , a slot 1312a is formed in the first connecting portion 131, and a plug 1321 is formed in the second connecting portion 132. The first connecting portion 131 includes a socket 1312 and a first circuit board 1313. The first circuit board 1313 is disposed in the power supply assembly 12. A mounting groove 12b is formed on the outer surface of the power supply assembly 12. The socket 1312 is disposed in the mounting groove 12b. The space within the socket 1312 defines a slot 1312a. The slot 1312a is exposed on the outer surface of the power supply assembly 12. One end of the elastic structure 1311 abuts against the plug 1321, and the other end passes through the socket 1312 and is electrically connected to the first circuit board 1313.

[0076] The slot 1312 a is formed on the first connection portion 131 , and the inserting piece 1321 is formed on the second connection portion 132 . This means that the slot 1312 a is provided on the power supply assembly 12 , and the inserting piece 1321 is provided on the host 11 .

[0077] The space within the socket 1312 defines a slot 1312 a. Specifically, the socket 1312 is formed with a plurality of slots 1312 a arranged along the second direction and not connected to each other at one end exposed on the outer surface of the power supply assembly 12 for inserting the plug 1321 .

[0078] Illustratively, the mounting groove 12 b formed on the outer surface of the power supply assembly 12 is located at an end of the power supply assembly 12 away from the first opening 111 b along the first direction.

[0079] One end of the socket 1312 is inserted into the installation opening, that is, extends from the installation opening into the interior of the power supply assembly 12 and is electrically connected to the first circuit board 1313 inside the power supply assembly 12 .

[0080] The slot 1312a is exposed on the outer surface of the power supply assembly 12, which means that the slot 1312a can be seen when the power supply assembly 12 is used as an independent component. When the power supply assembly 12 is inserted into the accommodating cavity 111a, the slot 1312a exposed on the outer surface of the power supply assembly 12 can be connected to the plug 1321. Here, the outer surface of the slot 1312a can be flush with the outer surface of the power supply assembly 12, or it can protrude from the outer surface of the power supply assembly 12. Of course, it can also be recessed in the outer surface of the power supply assembly 12, and this is not limited here.

[0081] One end of the elastic structure 1311 abuts against the plug 1321, and the other end passes through the socket 1312 and is electrically connected to the first circuit board 1313, thereby forming a circuit path from the first circuit board 1313, the elastic structure 1311 to the plug 1321, so that the electric energy output by the power supply component 12 can be transmitted to the host 11.

[0082] Exemplarily, the first circuit board 1313 is also connected to the battery in the power supply assembly 12 , thereby forming a circuit path from the battery, the first circuit board 1313 , the elastic structure 1311 to the insert 1321 .

[0083] For some examples, see Figures 3 to 5, a slot 1312a is formed in the first connecting portion 131, and an insert 1321 is formed in the second connecting portion 132. The housing assembly 111 also has a mounting cavity 111d. The mounting cavity 111d and the accommodating cavity 111a are arranged along a third direction. The housing assembly 111 has a connecting port 111e. The connecting port 111e connects the mounting cavity 111d and the accommodating cavity 111a. The second connecting portion 132 includes a connecting structure 1322 and a second circuit board 1323. The second circuit board 1323 is arranged in the mounting cavity 111d. The connecting structure 1322 is passed through the connecting port 111e. One end of the insert 1321 passes through the connecting structure 1322 and is electrically connected to the second circuit board 1323, and the other end is connected to one end of the connecting structure 1322 facing the connecting port 111e, and protrudes from the side wall of the accommodating cavity 111a through the connecting port 111e. The third direction is perpendicular to the first direction.

[0084] The slot 1312 a is formed on the first connection portion 131 , and the inserting piece 1321 is formed on the second connection portion 132 . This means that the slot 1312 a is provided on the power supply assembly 12 , and the inserting piece 1321 is provided on the host 11 .

[0085] The installation cavity 111d and the accommodating cavity 111a are arranged along the third direction. That is, when the power supply assembly 12 is combined with the main body 11, the power supply assembly 12 and the air pump assembly 20 are arranged side by side along the third direction.

[0086] The communication port 111 e communicates with the installation cavity 111 d and the accommodating cavity 111 a , wherein the communication port 111 e is located at one end of the housing assembly 111 away from the first opening 111 b along the first direction.

[0087] Specifically, a portion of the insert 1321 is disposed in the mounting cavity 111d and electrically connected to the second circuit board 1323, and the other portion extends from the mounting cavity 111d to the accommodating cavity 111a through the connecting port 111e, and protrudes from the side wall of the accommodating cavity 111a through the connecting port 111e, so that the insert 1321 can extend into the slot 1312a and form an electrical connection with the elastic structure 1311.

[0088] It should be noted that the connection structure 1322 is used to install and fix the inserting piece 1321 so that the inserting piece 1321 can be stably inserted into each slot 1312 a and connected to the elastic structure 1311 .

[0089] For some examples, see Figure 1 、 Figure 2 and Figure 4 The housing assembly 111 has a second opening 111c on one side away from the first opening 111b along the first direction. The end surface of the power supply assembly 12 away from the first opening 111b is exposed at the second opening 111c, so that the power supply assembly 12 can be separated from the main unit 11 through the second opening 111c and the first opening 111b.

[0090] The housing component 111 has a second opening 111 c on one side away from the first opening 111 b along the first direction. That is, the first opening 111 b and the second opening 111 c are arranged relative to the housing component 111 along the first direction.

[0091] The end face of the power supply component 12 away from the first opening 111b is exposed at the second opening 111c, that is, the second opening 111c is connected to the accommodating cavity 111a, so that the end face of the power supply component 12 away from the first opening 111b can be exposed at the second opening 111c, so that the user can apply force to the power supply component 12 in the accommodating cavity 111a through the second opening 111c or the first opening 111b, so that the power supply component 12 is separated from the main unit 11 through the first opening 111b or the first opening 111b.

[0092] It should be noted that the exposure in this application can be flush with the outer surface, protruding or recessed.

[0093] Exemplarily, the projection size of the second opening 111c on a plane perpendicular to the first direction is smaller than the projection size of the power supply component 12 on a plane perpendicular to the first direction, so that the second opening 111c can abut and limit the end face of the power supply component 12 away from the first opening 111b, preventing the power supply component 12 from extending out of the accommodating cavity 111a through the second opening 111c and separating from the main unit 11.

[0094] For some examples, see Figure 1 、 Figure 3 and Figure 7 The edge of the second opening 111 c at least covers the inserting piece 1321 and the slot 1312 a.

[0095] That is to say, the shell component 111 where the second opening 111c is located and the end face of the power supply component 12 exposed in the second opening 111c can cover the plug 1321 and the slot 1312a. When the power supply component 12 is docked with the host 11, the plug 1321 and the slot 1312a cannot be seen from the outside, and the electrical connection between the power supply component 12 and the host 11 is hidden in the accommodating cavity 111a, thereby increasing the stability of the electrical connection, improving the situation where external dust, water or other impurities enter the connector 13 and cause the electrical connection to be unstable or fail, and improving the service life of the connector 13.

[0096] For some examples, see Figure 1 、 Figure 5 and Figure 7The housing assembly 111 further includes an installation cavity 111d, which is arranged along a third direction with the accommodating cavity 111a. The host 11 includes a charging module 113, which is disposed within the installation cavity 111d and electrically connected to the connector 13. The charging module 113 has a first power supply interface 113a. The first power supply interface 113a is exposed along a first direction on an outer surface of the housing assembly 111 near the second opening 111c. The third direction is perpendicular to the first direction.

[0097] It should be noted that the first power supply interface 113 a is used to provide power to the power supply assembly 12 .

[0098] Exemplarily, one end of the charging module 113 is connected to the first power supply interface 113a, and the other end is connected to the second circuit board 1323, so that the power supply component 12 can be charged in sequence through the first power supply interface 113a, the charging module 113, the second circuit board 1323, and the plug-in structure.

[0099] Exemplarily, the first power supply interface 113 a is a fast charging interface. When the power supply assembly 12 is combined with the host 11 , the power supply assembly 12 can be quickly charged through the first power supply interface 113 a on the host 11 .

[0100] The first power supply interface 113a is exposed along the first direction on the outer surface of the housing assembly 111 near the second opening 111c, so that the first power supply interface 113a is closer to the second circuit board 1323 and the plug-in structure, thereby improving the compactness of the host 11 structure.

[0101] For some examples, see Figure 1 、 Figure 4 and Figure 7 The power supply assembly 12 includes a second power supply interface 121 , which is disposed on a side end surface of the power supply assembly 12 close to the second opening 111 c and is exposed to the outer surface of the housing assembly 111 through the second opening 111 c .

[0102] The second power supply interface 121 is disposed on one side of the power supply assembly 12 near the second opening 111 c and is exposed on the outer surface of the housing assembly 111 through the second opening 111 c , so that the second power supply interface 121 can be used when the power supply assembly 12 is combined with the host 11 .

[0103] It should be noted that the second power supply interface 121 can be used to charge the power supply assembly 12 from an external power source, and can also be used by the power supply assembly 12 to charge external devices.

[0104] Exemplarily, the second power supply interface 121 may be a USB interface and / or a Type-C interface.

[0105] For some examples, see Figure 2 and Figure 4 At least part of the side wall of the power supply component 12 protrudes outward to form an anti-fool structure 12a. The anti-fool structure 12a is arranged on the side of the power supply component 12 close to the first opening 111b. The shell component 111 is formed with a notch 111f. The notch 111f passes through one end of the shell component 111 close to the first opening 111b along the first direction and is connected to the first opening 111b. The anti-fool structure 12a matches the notch 111f along the first direction so that the first connection part 131 matches the second connection part 132.

[0106] It should be noted that the anti-foolproof structure 12a matches the notch 111f along the first direction. The anti-foolproof structure 12a can play a guiding and positioning role. When the power supply component 12 needs to be inserted into the accommodating cavity 111a, the insertion direction of the power supply component 12 is determined by the anti-foolproof structure 12a, which improves the situation where the second connecting part 132 easily scratches the outer wall of the power supply component 12 when the power supply component 12 is inserted upside down.

[0107] Specifically, if the end of the power supply component 12 provided with the anti-foolproof structure 12a is called the first end of the power supply component 12, and the end of the power supply component 12 provided with the first connecting portion 131 is called the second end, when the power supply component 12 is inserted into the accommodating cavity 111a along the first opening 111b from the second end to the first end, the setting of the anti-foolproof structure 12a can stop the insertion of the power supply component 12, and the power supply component 12 cannot be fully inserted into the accommodating cavity 111a, thereby reducing the chance of the power supply component 12 being scratched. When the power supply component 12 is inserted into the accommodating cavity 111a along the first opening 111b from the first end to the second end, it can be smoothly inserted into the accommodating cavity 111a, so that the first connecting portion 131 and the second connecting portion 132 match.

[0108] By setting the anti-foolproof structure 12a as a protruding structure and setting it on the side of the power supply component 12 close to the first opening 111b, the notch 111f is set at one end of the shell component 111 close to the first opening 111b and connected to the first opening 111b, so that the protruding structure can interfere with part of the shell component 111. On the one hand, it can prevent the power supply component 12 from being inserted upside down along the first direction when inserted into the accommodating cavity 111a. On the other hand, it can prevent the power supply component 12 from being inserted at a certain angle when inserted into the accommodating cavity 111a, so that the first connector and the second connector cannot be docked, thereby improving the situation where the outer surface of the power supply component 12 is easily scratched due to reverse insertion.

[0109] In one embodiment, the power supply assembly 12 further includes a power indicator light. The power indicator light is disposed on the foolproof structure 12a. The power indicator light disposed on the foolproof structure 12a can be observed by a user from outside the host 11. The power indicator light can also display the power status of the power supply and can provide a prompt when the power supply assembly 12 is charging.

[0110] A second aspect of an embodiment of the present application provides an air pump, which includes an air pump assembly 20 and a power supply device 10 provided in any embodiment of the present application. The air pump assembly 20 is disposed in the host 11 and electrically connected to the connector 13.

[0111] It should be noted that air pumps are generally used to inflate inflatable objects such as tires, balloons, and basketballs.

[0112] In the related art, the air pump is generally powered by a car battery or a built-in battery. Powering the air pump by a car battery requires a separate lead, which is more troublesome to use. Powering the air pump by a built-in battery usually makes the air pump larger in size and inconvenient to carry.

[0113] The air pump provided in the embodiment of the present application, on the one hand, by detachably docking the power supply assembly 12 with the host 11 along a first direction, realizes that the power supply assembly 12 can be used alone as a mobile power supply, and can be combined with the host 11 to power the host 11 to realize the functions of the host 11. On the other hand, by setting the first connecting part 131 on the side of the power supply component 12 away from the first opening 111b, and setting the second connecting part 132 on the main unit 11, the notch of the slot 1312a is at least along the first direction toward the plug 1321, so that the plug 1321 can be inserted into the slot 1312a along the first direction. In this way, during the insertion process of the power supply component 12, when the slot 1312a contacts the plug 1321, the plug 1321 can be directly inserted into the slot 1312a along the first direction. The docking is simple and convenient, and the chance of damage to the plug 1321 or the slot 1312a can be reduced. The connection between the plug 1321 and the slot 1312a makes the electrical connection between the power supply component 12 and the main unit 11 more stable and reliable, thereby improving the durability and safety of the electrical connection structure in the air pump.

[0114] For some examples, see Figures 3 to 5 The housing assembly 111 further includes a mounting cavity 111d. The air pump assembly 20 is disposed within the mounting cavity 111d and electrically connected to the second circuit board 1323 of the second connecting portion 132. The mounting cavity 111d and the accommodating cavity 111a are arranged along the third direction. The housing assembly 111 includes a communication port 111e. The communication port 111e connects the mounting cavity 111d and the accommodating cavity 111a. The insert 1321 protrudes from the sidewall of the accommodating cavity 111a through the communication port 111e. The first direction is perpendicular to the third direction.

[0115] It should be noted that the second circuit board 1323 is arranged in the installation cavity 111d and is electrically connected to the air pump assembly 20. At the same time, one end of the plug 1321 is connected to the second circuit board 1323, so that the current in the power supply assembly 12 can be transmitted to the air pump assembly 20 through the plug 1321 and the second circuit board 1323, thereby powering the air pump assembly 20 to drive the air pump assembly 20 to perform inflation operations.

[0116] A third aspect of the embodiments of the present application provides an emergency starting power supply, which includes a starting power supply module and a power supply device 10 provided by any embodiment of the present application, and the starting power supply module is arranged in the host 11.

[0117] It should be noted that the emergency starting power supply is usually used to start the vehicle when the vehicle's battery is low or the vehicle cannot be started for other reasons.

[0118] Exemplarily, the emergency starting power supply may further include an air pump assembly 20 , which is disposed together with the starting power supply module in the host 11 to have the functions of emergency starting the vehicle and inflation.

[0119] The emergency starting power supply provided in the embodiment of the present application, on the one hand, by detachably docking the power supply component 12 with the host 11 along the first direction, realizes that the power supply component 12 can be used alone as a mobile power supply, and can be combined with the host 11 to power the host 11 to realize the functions of the host 11. On the other hand, by setting the first connecting part 131 on the side of the power supply component 12 away from the first opening 111b, and the second connecting part 132 is set on the host 11, the notch of the slot 1312a is at least along the first direction toward the plug 1321, so that the plug 1321 can be inserted into the slot 1312a along the first direction. In this way, during the insertion process of the power supply component 12, when the slot 1312a contacts the plug 1321, the plug 1321 can be directly inserted into the slot 1312a along the first direction. The docking is simple and convenient, and the chance of damage to the plug 1321 or the slot 1312a can be reduced. The connection between the plug 1321 and the slot 1312a makes the electrical connection between the power supply component 12 and the host 11 more stable and reliable, thereby improving the durability and safety of the electrical connection structure in the emergency starting power supply.
