[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 "center," "upper," "lower," "top," "bottom," "inner," "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 and operate in a specific orientation, and therefore should not be construed as limiting the embodiments of the present application. In addition, 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 power supply components in the power supply device are usually non-detachable, resulting in a large overall size of the power supply device and making it inconvenient to carry.

[0040] Based on the above situation, the present application embodiment provides a power supply device 10, please refer to Figures 1 to 8 The power supply device 10 includes a host 11 and a power supply assembly 12. 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, an external device, or itself. The host 11 includes a housing assembly 111. The housing assembly 111 has a receiving cavity 111a and a first opening 111b. The power supply assembly 12 can extend into the receiving cavity 111a through the first opening 111b. The cavity wall of the receiving cavity 111a covers the outer periphery of 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 the lighting 124) 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 is the length direction of the host 11 and is perpendicular to the thickness direction of the host 11 .

[0046] The shell component 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 component 111 along the first direction. The accommodating cavity 111a extends along the first direction, so that the power supply component 12 can extend into the accommodating cavity 111a through the first opening 111b, and the cavity wall of the accommodating cavity 111a is covered around the outer periphery of the power supply component 12. The cavity wall of the accommodating cavity 111a can limit the power supply component 12, thereby improving the stability and reliability of the connection between the power supply component 12 and the shell component 111, and providing protection for the power supply component 12.

[0047] The cavity wall of the accommodating cavity 111a is wrapped around the periphery of the power supply component 12, which means that the cavity wall of the accommodating cavity 111a is wrapped around the outer side of the peripheral side wall of the power supply component 12. The wrapping here does not affect the corresponding functional operation of the power supply component 12, for example, it does not affect the button function of the power supply component 12. In this way, the accommodating cavity 111a will roughly surround the periphery of the power supply component 12 to form a fully enclosed structure. The accommodating cavity 111a is formed into a through-groove structure or a blind-groove structure. Both 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.

[0048] For example, the projection of the power supply assembly 12 on a plane perpendicular to the first direction does not exceed the projection 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 the power supply assembly 12 is more securely fixed to the host 11.

[0049] The power supply device 10 provided in the embodiment of the present application, on the one hand, by configuring the power supply assembly 12 to be detachably docked with the host 11 along a first direction, enables the power supply assembly 12 to be used alone as a mobile power supply to power its own internal electrical components, and to power the host 11 after being combined with the host 11, thereby realizing the functions of the host 11. On the other hand, through the accommodating cavity 111a and the first opening 111b of the shell assembly 111, the power supply assembly 12 can be extended into the accommodating cavity 111a through the first opening 111b, and the cavity wall of the accommodating cavity 111a is allowed to cover the outer periphery of the power supply assembly 12. In this way, the cavity wall of the accommodating cavity 111a can limit and protect the power supply assembly 12, thereby improving the stability and reliability of the connection between the power supply assembly 12 and the shell assembly 111, enhancing the compactness of the overall structure of the power supply device 10, and improving the aesthetics of the appearance of the power supply device 10.

[0050] For some examples, see Figures 1 to 7 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.

[0051] 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 disposed on opposite sides of the housing component 111 along the first direction.

[0052] 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.

[0053] It should be noted that the exposure in this application can be flush with, protruding from, or recessed from the outer surface of the housing assembly 111. In this way, the power supply assembly 12 can be provided with corresponding structures on one end surface located at the first opening 111b or one end surface located at the second opening 111c to achieve functions, for example, providing a power supply interface 125, a lighting structure, etc., and by being exposed on the outer surface of the housing assembly 111, corresponding operations are facilitated without interfering with the housing assembly 111.

[0054] For some examples, see Figure 2 and Figure 4In a plane projection perpendicular to the first direction, the projection of the second opening 111 c falls within the projection range of the power supply assembly 12 .

[0055] In this way, the second opening 111c can abut and limit the side of the power supply component 12 away from the first opening 111b, reducing the probability of the power supply component 12 escaping from the accommodating cavity 111a through the second opening 111c and separating from the host 11, and increasing the stability of the power supply component 12 accommodated in the accommodating cavity 111a.

[0056] For some examples, see Figures 4 to 7 One of the power supply assembly 12 and the housing assembly 111 is formed with one or more elastic hooks 112, and the other is formed with one or more slots 12a. The elastic hooks 112 are inserted into the slots 12a.

[0057] Exemplarily, the housing assembly 111 includes one or more elastic hooks 112, and one or more slots 12a are formed on the outer wall of the power supply assembly 12. The entire structure of the elastic hook 112 protrudes from the side wall of the accommodating cavity 111a, or part of the structure of the elastic hook 112 protrudes from the side wall of the accommodating cavity 111a, and the other part of the structure can be arranged outside the accommodating cavity 111a or flush with the side wall of the accommodating cavity 111a. The side wall protruding from the accommodating cavity 111a here can be connected to the side wall of the accommodating cavity 111a, or it can be not connected to the side wall of the accommodating cavity 111a but protrudes from the position of the side wall of the accommodating cavity 111a, so that at least part of the elastic hook 112 is located on the insertion path of the power supply assembly 12.

[0058] It should be noted that the number of the elastic hooks 112 and the number of the slots 12 a may be the same or different.

[0059] It should be noted that the elastic hook 112 refers to a structure that can at least partially undergo elastic deformation.

[0060] Specifically, at least part of the elastic hook 112 is located on the path of the power supply component 12 inserted into the accommodating cavity 111a. In the process of the power supply component 12 extending into the accommodating cavity 111a, the power supply component 12 contacts the elastic hook 112, and the elastic hook 112 forms a barrier to the continued extension of the power supply component 12. In this case, the elastic hook 112 is elastically deformed by the force of the power supply component 12, so that the power supply component 12 can continue to extend into the accommodating cavity 111a, until the slot 12a on the power supply component 12 moves to the position of the elastic hook 112, the elastic hook 112 hooks into the slot 12a, abuts against the slot 12a, and restores its own deformation, so that the power supply component 12 can stably extend into the accommodating cavity 111a and is not easy to move or loosen.

[0061] It should be noted that when the elastic hook 112 is inserted into the slot 12a, the elastic hook 112 can fully or partially recover its elastic deformation. It is understood that the partial recovery of the elastic deformation allows the elastic hook 112 to abut against the slot 12a, forming a certain latching force, thereby further improving the fixing reliability of the power supply assembly 12.

[0062] The elastic hook 112 is inserted into the slot 12a, so that the housing assembly 111 can limit the power supply assembly 12 in the first direction, preventing the power supply assembly 12 from accidentally separating from the housing assembly 111 and falling out of the accommodating cavity 111a.

[0063] For example, there can be two elastic hooks 112 and two slots 12a, each corresponding to one of the elastic hooks 112. This allows the power supply assembly 12 to be positioned in different directions and positions, thereby increasing the stability of the power supply assembly 12. The two elastic hooks 112 and the two slots 12a can be symmetrically arranged relative to the central axis of the accommodating cavity 111a.

[0064] In addition, when one of the elastic hooks 112 has a problem, the other elastic hook 112 can also dock with the corresponding slot 12 a to complete the position limiting of the power supply assembly 12 .

[0065] The specific structure and forming method of the elastic hook 112 are not limited.

[0066] In some embodiments, the slot 12a is formed on the outer wall of the power supply assembly 12, the elastic hook 112 is formed on the shell assembly 111, and part of the side wall of the accommodating cavity 111a protrudes toward the side close to the power supply assembly 12 to form the elastic hook 112.

[0067] That is to say, the elastic hook 112 is formed on the side wall of the accommodating cavity 111 a , and the elastic hook 112 is not an independent structure, thereby increasing the overall structural strength, reducing parts, and improving assembly efficiency.

[0068] In other embodiments, please refer to Figure 4 、 Figure 6 and Figure 7 The card slot 12a is formed on the outer wall of the power supply component 12, the elastic hook 112 is formed on the housing component 111, and a through-hole 111d is provided on the side wall of the accommodating cavity 111a. The elastic hook 112 includes an elastic structure 1121 and a snap 1122. The elastic structure 1121 is connected to the edge of the through-hole 111d facing away from the accommodating cavity 111a. The snap 1122 is provided on the side of the elastic structure 1121 facing the accommodating cavity 111a. The snap 1122 is provided through the through-hole 111d to be inserted into the card slot 12a.

[0069] It should be noted that the through opening 111d here penetrates the side wall of the accommodating cavity 111a, and the elastic hook 112 and the side wall of the accommodating cavity 111a are designed to be separate. In other words, in this embodiment, the elastic hook 112 is a structure independent of the accommodating cavity 111a, and cooperates with the card slot 12a.

[0070] In addition, the spring buckle 1122 is used to contact the power supply assembly 12 and undergo elastic deformation under the action of the power supply assembly 12, and is engaged with the card slot 12a. The elastic structure 1121 is used to form a force arm, driving the spring buckle 1122 to engage with the card slot 12a through the through-hole 111d. When the power supply assembly 12 contacts the spring buckle 1122 and a force is applied to the spring buckle 1122, the spring buckle 1122 transmits the force to the elastic structure 1121, and the elastic structure 1121 then undergoes elastic deformation in a direction away from the accommodating cavity 111a, driving the spring buckle 1122 to move in a direction away from the accommodating cavity 111a, thereby improving the situation where the sliding contact force between the spring buckle 1122 and the outer wall of the power supply assembly 12 is too large, which easily causes scratches on the outer wall of the power supply assembly 12.

[0071] The elastic structure 1121 is connected to the edge of the side of the through-opening 111d away from the accommodating cavity 111a, which means that the connection position between the elastic structure 1121 and the side wall of the accommodating cavity 111a is outside the accommodating cavity 111a. The elastic structure 1121 can hardly occupy the space in the accommodating cavity 111a. The elastic structure 1121 does not contact the power supply component 12, and the elastic structure 1121 has enough space to move outside the accommodating cavity 111a, which is convenient for driving the spring buckle 1122 to move and reducing the probability of damage to the power supply component 12 caused by sliding contact between the elastic structure 1121 and the power supply component 12.

[0072] It is understandable that the elastic structure 1121 is connected to some edges of the through opening 111d away from the accommodating cavity 111a. The connection here can be a fastening connection or a snap connection, etc., which is not limited here.

[0073] The spring buckle 1122 is disposed on the side of the elastic structure 1121 facing the accommodating cavity 111a, so that the spring buckle 1122 can directly pass through the through opening 111d, extend into the accommodating cavity 111a, and be inserted into the slot 12a, making the structure of the elastic hook 112 simpler.

[0074] For some examples, see Figure 4 、 Figure 6 and Figure 7 The wall of the through-opening 111d is spaced apart from the elastic structure 1121 .

[0075] It should be noted that the through-opening 111d usually has a certain thickness, that is, the thickness of the side wall of the accommodating cavity 111a. In other words, the through-opening 111d can be understood as a channel, and the wall of the through-opening 111d refers to the inner wall of the channel.

[0076] By spacing the wall of the through-opening 111d and the elastic structure 1121, a certain gap is created between the elastic structure 1121 and the wall of the through-opening 111d, thereby reducing interference between the elastic structure 1121 and the through-opening 111d and facilitating elastic deformation of the elastic structure 1121 in a direction away from the accommodating cavity 111a.

[0077] The specific structure of the elastic structure 1121 is not limited.

[0078] For some examples, see Figure 6 The elastic structure 1121 includes a connecting frame 1121a, a positioning structure 1121b and a connecting ear 1121c. The spring buckle 1122 is connected to the side of the connecting frame 1121a facing the through-opening 111d. The side of the connecting frame 1121a facing away from the through-opening 111d has an opening groove 1121d. The groove walls at the opposite ends of the opening groove 1121d along the first direction protrude in directions away from each other to form the positioning structure 1121b and the connecting ear 1121c respectively. A positioning groove 111e is formed in the shell assembly 111. The positioning structure 1121b is inserted into the positioning groove 111e. The elastic structure 1121 is connected to the edge of the through-opening 111d through the connecting ear 1121c.

[0079] The connecting frame 1121a has an open slot 1121d on one side facing away from the through-opening 111d, forming a bow-like lever arm structure. The groove walls at opposite ends of the open slot 1121d along the first direction, i.e., the two ends of the lever arm structure along the first direction, protrude away from each other to form a positioning structure 1121b and a connecting ear 1121c, respectively. The cooperation between the positioning structure 1121b and the positioning slot 111e facilitates positioning and installation of the elastic structure 1121. The elastic structure 1121 is connected to the edge of the through-opening 111d facing away from the accommodating cavity 111a via the connecting ear 1121c, thereby increasing the stability of the elastic structure 1121.

[0080] For example, the connecting ear 1121c can be connected to the edge of the through-opening 111d facing away from the accommodating cavity 111a by means of a threaded connection.

[0081] For some examples, see Figures 7 and 8The power supply assembly 12 has a first electrical connection terminal 121 on a side away from the first opening 111b. The host 11 is provided with a second electrical connection terminal 113. The power supply assembly 12 is electrically connected to the host 11 through the first electrical connection terminal 121 and the second electrical connection terminal 113.

[0082] The power supply assembly 12 has a first electrical connection end 121 on a side away from the first opening 111 b , that is, the first electrical connection end 121 is on a side of the power supply assembly 12 close to the second opening 111 c .

[0083] It can be understood that the second electrical connection end 113 is disposed on the cavity wall of the accommodating cavity 111 a of the housing assembly 111 corresponding to the first electrical connection end 121 and is close to the second opening 111 c .

[0084] The first electrical connection end 121 and the second electrical connection end 113 may be spring-type connectors, thimble-type connectors, blade connectors, and the like.

[0085] For example, the power supply assembly 12 is electrically connected to the host 11 via a blade connector. A male connector is provided on the host 11, and a female connector with dual springs is provided on the power supply assembly 12. The metal portion of the female connector of the power supply assembly 12 is hidden inside the power supply assembly 12, thereby preventing accidental electric shock to the user and improving product safety. Furthermore, the blade connector can enhance the stability and reliability of the electrical connection.

[0086] For some examples, see Figure 1 、 Figure 3 and Figure 7 At least a portion of the sidewall of the power supply assembly 12 protrudes outward to form an anti-fool structure 12b. The anti-fool structure 12b is disposed on a side of the power supply assembly 12 near the first opening 111b. The housing assembly 111 is formed with a notch 111f. The notch 111f extends through one end of the housing assembly 111 near the first opening 111b along a first direction and communicates with the first opening 111b. The anti-fool structure 12b mates with the notch 111f along the first direction, so that the first electrical connection end 121 mates with the second electrical connection end 113.

[0087] It should be noted that the anti-foolproof structure 12b matches the notch 111f along the first direction. Its function is to guide the insertion of the power supply component 12 into the accommodating cavity 111a to prevent the power supply component 12 from being inserted upside down when extending into the accommodating cavity 111a, thereby causing the first connector and the second connector to be unable to connect, and improving the situation where the second connector easily scratches the outer wall of the power supply component 12 when the power supply component 12 is inserted upside down.

[0088] By setting the anti-foolproof structure 12b 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 into the accommodating cavity 111a with a certain angle of deflection, so that the first connector and the second connector cannot be docked.

[0089] For some examples, see Figure 1 、 Figure 3 and Figure 8 The foolproof structure 12b is exposed on the outer surface of the housing assembly 111 through the notch 111f. The power supply assembly 12 includes a power indicator light 122. The power indicator light 122 is provided on the foolproof structure 12b.

[0090] The fool-proof structure 12b is exposed on the outer surface of the shell assembly 111 through the notch 111f, which is conducive to the power indicator light 122 set on the fool-proof structure 12b being observed by the user from outside the host 11. At the same time, the power indicator light 122 can display the power status of the power supply and can provide a prompt when the power supply assembly 12 is charging.

[0091] For some examples, see Figures 1 to 3 as well as Figure 7 The power supply assembly 12 includes a power button 123. The housing assembly 111 is provided with a clearance opening 111g. The clearance opening 111g extends through the outer wall of the housing assembly 111 and the side wall of the accommodating chamber 111a. The power button 123 is exposed on the outer surface of the housing assembly 111 through the clearance opening 111g, and the edge of the power button 123 is spaced apart from the edge of the clearance opening 111g.

[0092] Illustratively, the power button 123 is used to turn on or off the power supply assembly 12 .

[0093] Illustratively, the power button 123 is used to turn on or off the lighting lamp 124 .

[0094] The power button 123 is exposed on the outer surface of the shell assembly 111 through the avoidance opening 111g, and the edge of the power button 123 is spaced apart from the edge of the avoidance opening 111g, which means that the power button 123 is recessed from the outer surface of the shell assembly 111, thereby enhancing the protection of the power button 123.

[0095] Here, by setting a avoidance opening 111g that passes through the outer wall of the shell assembly 111 and the side wall of the accommodating cavity 111a, the avoidance opening 111g can connect the outside world with the accommodating cavity 111a, and the edge of the power button 123 is spaced apart from the edge of the avoidance opening 111g. In this way, there is a gap between the power button 123 and the avoidance opening 111g, so that when the power supply assembly 12 extends into the accommodating cavity 111a, the power button 123 will not interfere with the side wall of the accommodating cavity 111a, thereby scratching and damaging the power button 123.

[0096] For some examples, see Figures 1 to 3 as well as Figure 8 The power supply assembly 12 includes a lighting lamp 124 and a power supply interface 125. The lighting lamp 124 is provided on an end surface of the power supply assembly 12 near the first opening 111b and is exposed to the outer surface of the housing assembly 111 through the first opening 111b. The power supply interface 125 is provided on an end surface of the power supply assembly 12 near the second opening 111c and is exposed to the outer surface of the housing assembly 111 through the second opening 111c.

[0097] The lighting lamp 124 can be used for lighting or for flashing warning.

[0098] The lighting lamp 124 is disposed on one end surface of the power supply assembly 12 near the first opening 111 b and is exposed on the outer surface of the housing assembly 111 through the first opening 111 b , so that the lighting lamp 124 can be used when the power supply assembly 12 is combined with the host 11 .

[0099] The power supply interface 125 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 power supply interface 125 can also be used when the power supply assembly 12 is combined with the host 11 .

[0100] It should be noted that the power supply interface 125 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.

[0101] Exemplarily, the power supply interface 125 may be a USB interface or a Type-C interface.

[0102] 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, wherein the air pump assembly 20 is disposed in a host 11 .

[0103] It should be noted that air pumps are generally used to inflate inflatable objects such as tires, balloons, and basketballs.

[0104] 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.

[0105] The air pump provided in the embodiment of the present application, by detachably docking the power supply assembly 12 with the main unit 11 along a first direction, realizes that the power supply assembly 12 can be used alone as a mobile power source to power its own internal electrical components, and can also power the main unit 11 after being combined with the main unit 11, so as to realize the inflation function of the air pump. In addition, through the accommodating cavity 111a and the first opening 111b of the shell assembly 111, the power supply assembly 12 can be extended into the accommodating cavity 111a through the first opening 111b, and the cavity wall of the accommodating cavity 111a is covered on the outer periphery of the power supply assembly 12. In this way, the cavity wall of the accommodating cavity 111a can limit and protect the power supply assembly 12, thereby improving the stability and reliability of the connection between the power supply assembly 12 and the shell assembly 111, improving the compactness of the overall structure of the air pump, and improving the aesthetics of the appearance of the air pump.

[0106] For some examples, see Figures 5 to 7 The shell assembly 111 includes a middle frame 1111 and an outer shell 1112. The space inside the middle frame 1111 defines an installation cavity 1111a and an accommodating cavity 111a. The installation cavity 1111a is arranged on one side of the accommodating cavity 111a along the second direction. The outer shell 1112 is sleeved on the outer periphery of the middle frame 1111. The air pump assembly 20 is arranged in the installation cavity 1111a. The second direction intersects with the first direction.

[0107] Exemplarily, the second direction is perpendicular to the first direction.

[0108] The air pump assembly 20 is arranged in the installation cavity 1111a, and the installation cavity 1111a is arranged on one side of the accommodating cavity 111a along the second direction. That is, when the power supply assembly 12 is combined with the host 11, the power supply assembly 12 and the air pump assembly 20 are arranged side by side along the second direction.

[0109] Exemplarily, a seal is formed between the installation cavity 1111 a and the accommodating cavity 111 a , so that the airflow generated by the air pump assembly 20 when it is working will not enter the accommodating cavity 111 a and come into contact with the power supply assembly 12 .

[0110] 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.

[0111] 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.

[0112] 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.

[0113] The emergency starting power supply provided in the embodiment of the present application realizes that the power supply assembly 12 can be used alone as a mobile power supply to power its own internal electrical components, and can also be used to power the host 11 after being combined with the host 11 to realize the emergency starting function of the emergency starting power supply. In addition, through the accommodating cavity 111a and the first opening 111b of the shell assembly 111, the power supply assembly 12 can be inserted into the accommodating cavity 111a through the first opening 111b, and the cavity wall of the accommodating cavity 111a is wrapped around the outer periphery of the power supply assembly 12. In this way, the cavity wall of the accommodating cavity 111a can limit and protect the power supply assembly 12, thereby improving the stability and reliability of the connection between the power supply assembly 12 and the shell assembly 111, enhancing the compactness of the overall structure of the emergency starting power supply, and improving the aesthetics of the emergency starting power supply.
