The embodiments of the present application do not impose any special restrictions on the above-mentioned electrical devices.

[0032] In order to better understand this application, Figures 1 to 5 The domain control battery pack and power-consuming device according to the application embodiments are described in detail.

[0033] At present, in some domain control battery packs, the domain controller and the battery box are usually arranged in a nested connection mode, that is, the domain controller at least partially extends into the battery box. On this basis, the domain controller and the battery box are usually connected and fixed by external connection. That is to say, the part of the domain controller outside the battery box is connected to the outside of the battery box to connect and fix the two. This connection method has low connection strength, and the domain controller is easily affected by external vibration interference and vibrates, which is not conducive to the reliability of electrical connection and easily causes safety problems.

[0034] Based on the above-mentioned defects, an embodiment of the present application provides a domain controller battery pack, in which the part of the domain controller located in the battery box is detachably connected to the box body through the shock absorbing assembly of the battery box, so that the part of the domain controller located in the battery box can be connected to the box body, which is beneficial to improve the connection strength between the domain controller and the battery box, thereby helping to improve the structural strength and reliability of the domain controller battery pack.

[0035] The domain control battery pack provided in the embodiment of the present application can be produced and sold separately as an independent component. Of course, it can also be used as a domain control battery pack of an electrical device and serve as a component of the electrical device.

[0036] Please also read Figures 1 to 4, an embodiment of the present application provides a domain control battery pack, including a battery box 10 and a domain controller 20. The battery box 10 includes a box body 11 and a shock absorbing assembly 12, the box body 11 has a accommodating cavity 101 and an opening 102 communicating with the accommodating cavity 101, and the shock absorbing assembly 12 is arranged in the accommodating cavity 101 and connected to the box body 11. The domain controller 20 is arranged to close the opening 102, and the domain controller 20 includes a first main body 21 located outside the accommodating cavity 101, and a second main body 22 extending from the opening 102 into the accommodating cavity 101, and the second main body 22 is detachably connected to the box body 11 through the shock absorbing assembly 12.

[0037] In the domain controller battery pack provided in the embodiment of the present application, the second main body 22 of the domain controller 20 extending into the accommodating cavity 101 of the box body 11 is detachably connected to the box body 11 through the shock absorbing assembly 12, so that the domain controller can be connected to the box body 11 through its part located in the accommodating cavity 101, so as to strengthen the connection strength between the part of the domain controller 20 extending into the accommodating cavity 101 and the box body 11, thereby facilitating the improvement of the connection strength between the domain controller 20 as a whole and the battery box 10, and the shock absorbing assembly 12 can reduce or even absorb the vibration force of the second main body 22, thereby preventing the domain controller 20 from being displaced due to external vibration, and facilitating the improvement of the structural strength and reliability of the domain controller battery pack.

[0038] It is understandable that when the domain control battery pack is subject to external vibration interference (for example, dangerous situations such as collision and sudden braking occur during vehicle driving), since the domain controller 20 includes a second main body 22 extending into the accommodating cavity 101, and the second main body 22 is connected to the box body 11 through the shock absorbing assembly 12, it can prevent the domain controller 20 from being displaced, which is beneficial to ensure the electrical connection between the domain controller 20 and the battery cells in the box body 11, thereby helping to improve the reliability of the domain control battery pack.

[0039] The first direction X may be the width direction of the box body 11 , the second direction Y may be the length direction of the box body 11 , and the third direction Z may be the height direction of the box body 11 .

[0040] The embodiment of the present application proposes a domain control battery pack, wherein the battery box 10 is used to accommodate the battery assembly to protect it, and the battery box 10 includes a box body 11 and a shock absorbing assembly 12, wherein the box body 11 has a receiving cavity 101 and an opening 102, and the shock absorbing assembly 12 is disposed in the receiving cavity 101 and connected to the box body 11. Specifically, the battery assembly includes a plurality of battery cells, and the battery assembly is disposed in the receiving cavity 101 and is located on the side of the shock absorbing assembly 12 away from the opening 102 along the second direction Y, so as to prevent the second main body 22 of the domain controller 20 extending into the receiving cavity 101 from the opening 102 from interfering with the battery assembly, so as to better protect the battery assembly and improve the safety and reliability of the domain control battery pack. The battery box 10 also includes a box cover, which is connected to the box body 11 so that the receiving cavity 101 forms a closed space.

[0041] Furthermore, the second main body portion 22 extends from the opening 102 into the accommodating cavity 101, so that the domain controller 20 forms a partially embedded structure, thereby making it easier to align the first main body portion 21 with the opening 102 and making the connection between the two more stable. At the same time, it can shorten the distance between the functional module and the battery assembly located at the installation position of the first main body portion 21 and / or the second main body portion 22, thereby facilitating electrical connection.

[0042] The domain controller 20 is used to integrate and install functional modules. Optionally, the domain controller 20 has multiple installation positions, and the installation positions are used to install functional modules. The functional modules are electrically connected to the battery assembly. Optionally, the first main body 21 can be equipped with an installation position, and the second main body 22 can also be equipped with an installation position. Of course, both the first main body 21 and the second main body 22 can be equipped with an installation position.

[0043] The domain controller 20 is connected to the battery box 10 and is correspondingly arranged at the position of the opening 102 to close the opening 102, so that on the basis of satisfying the connection between the two, the sealing of the battery box 10 is guaranteed to prevent foreign matter from entering the accommodating cavity 101, which is beneficial to ensuring the safety of the battery box 10 and thus the reliability of the domain control battery pack.

[0044] Optionally, the first main body portion 21 and the second main body portion 22 are configured as an integrally formed structure, which helps to reduce the difficulty of assembly. Of course, the two can also be provided separately, which helps to improve the flexibility of use.

[0045] The first main body 21 is located outside the accommodating cavity. Optionally, the first main body 21 and the box body can be arranged to be in abutting connection, detachable connection, or fixed connection.

[0046] In some embodiments, the first main body 21 is detachably connected to the box. By setting it in this way, the parts of the domain controller 20 located inside and outside the accommodating cavity 101 can be connected and fixed to the battery box 10, so that the two can be doubly connected and fixed, so as to strengthen the connection strength between the part of the domain controller 20 extending into the accommodating cavity 101 and the battery box 10, which is conducive to improving the connection strength between the two, thereby helping to improve the structural strength and reliability of the domain control battery pack. In addition, by setting the first main body 21 and the second main body 22 to be detachably connected to the battery box 10, it is also convenient to assemble and disassemble, so as to facilitate the maintenance or replacement of the domain controller 20.

[0047] Optionally, the first main body 21 may be detachably connected to the box body 11 by fasteners such as bolts, screws, and rivets.

[0048] In some optional embodiments, the domain controller further includes a first connection portion 24 connected to the peripheral side of the first main body portion 21 , and the first main body portion 21 is detachably connected to the box body 11 through the first connection portion 24 .

[0049] Optionally, the first main body 21 includes a first plate, the first plate is extended along the third direction Z, at least part of the functional modules are arranged on the first plate, and the first connecting portion 24 is arranged on the peripheral side of the first plate to facilitate connection with the box body 11. Optionally, the first main body 21 also includes a connecting frame, the connecting frame has a bearing cavity and has two openings connected to the bearing cavity along the second direction Y, the first plate is connected to a side of the connecting frame away from the box body 11 along the second direction Y and closes one of the openings, at least part of the functional modules are arranged on the connecting frame, and the first connecting portion 24 is arranged on the peripheral side of the opening of the connecting frame to facilitate connection with the box body 11.

[0050] The first connection portion 24 may be arranged to extend along the circumference of the first main body portion 21 and surround at least a portion of the first main body portion 21. It is understandable that, in order to facilitate the connection between the first main body portion 21 and the box body 11, the orthographic projection of the first connection portion 24 in the second direction Y surrounds the opening 102 and is staggered with the opening 102, so that the first connection portion 24 can abut against the box body 11 while the first main body portion 21 is arranged directly opposite the opening 102, and is stably connected in the abutting area.

[0051] Optionally, the second main body 22 includes a second plate, the second plate is extended along the second direction Y, at least part of the functional modules are arranged on the second plate, and the second main body 22 is connected to the shock absorbing assembly 12 at a side away from the first main body 21 along the second direction Y. Optionally, the second main body 22 also includes a side plate, the number of which is set to two, and the two side plates are respectively connected to the two ends of the second plate in the first direction X and are respectively connected to the first plate to avoid tilting or bending of the second plate, which is conducive to improving the structural strength of the domain control battery pack.

[0052] In some embodiments, the second main body 22 of the domain controller 20 extending into the accommodating cavity 101 can be detachably connected to the shock absorbing assembly 12 by fasteners such as bolts, screws, and rivets, and the shock absorbing assembly 12 and the box body 11 can be detachably connected by fasteners such as bolts, screws, and rivets, so that the second main body 22 can be detachably connected to the box body 11 through the shock absorbing assembly 12.

[0053] Optionally, the domain controller 20 is connected to the box body 11 by a plurality of fasteners, and the domain controller 20 is connected to the shock absorbing assembly 12 by a plurality of fasteners, which is beneficial to improving the connection effect and further improving the structural strength of the domain controller battery pack.

[0054] Optionally, the shock absorbing assembly 12 is connected to the bottom wall of the box body 11 along the third direction Z, and the box cover is arranged on the other side of the box body 11 along the third direction Z and opposite to the bottom wall to avoid interference between the shock absorbing assembly 12 and the box cover. The shock absorbing assembly 12 can also be connected to at least one side of the box body 11 along the second direction Y to improve the connection strength between the shock absorbing assembly 12 and the box body 11, thereby improving the connection strength between the domain controller 20 and the box body 11.

[0055] In some embodiments, the shock absorbing assembly 12 may also be fixedly connected to the second main body 22 and detachably connected to the box body 11, or the shock absorbing assembly 12 may also be fixedly connected to the box body 11 and detachably connected to the second main body 22, so that the second main body 22 can be detachably connected to the box body 11 through the shock absorbing assembly 12.

[0056] In some examples, the shock absorbing assembly 12 can also be provided separately from the box body 11 to facilitate processing and manufacturing, and the material of the shock absorbing assembly 12 can be the same as that of the box body 11, or can be different to improve the flexibility of use. For example, the shock absorbing assembly 12 can be provided as a sheet metal structure.

[0057] It is understandable that the domain control battery pack provided in the embodiment of the present application can improve the existing box body 11. It is only necessary to assemble the shock absorbing assembly 12 on the box body 11 and process the second main body 22 into a structure that can be connected to the shock absorbing assembly 12. This can improve the connection strength while reducing costs.

[0058] The specific assembly process of a domain control battery pack provided by the embodiment of the present application is as follows: the domain controller 20 extends into the accommodating cavity 101 through the opening 102, so that the first main body 21 is located outside the accommodating cavity 101 and the second main body 22 is located inside the accommodating cavity 101, the first main body 21 is connected to the box body 11 through a fastener, wherein the fastener extends from the outside of the accommodating cavity 101 into the first main body 21 and the box body 11 in sequence, the operation space is large, and the operation is convenient, the second main body 22 is connected to the shock absorbing assembly 12 through a fastener, wherein the fastener extends from the inside of the accommodating cavity 101 into the shock absorbing assembly 12 and the first main body 21 in sequence, the operation space is large, and the operation is convenient, after the domain controller 20 is connected and fixed to the box body 11, the box cover is connected to the box body 11, and the assembly of the domain control battery pack is completed. Accordingly, when the domain control battery pack has a disassembly requirement, it is only necessary to open the box cover, remove the fasteners between the domain controller 20 and the shock absorbing assembly 12, and the fasteners between the domain controller 20 and the box body 11.

[0059] See also Figures 1 to 5 In some optional embodiments, the shock absorbing assembly 12 includes a first shock absorbing member 121 , which is connected to the box body 11 and is detachably connected to the second connecting portion 23 .

[0060] The first shock absorber 121 is used to connect to the box body 11 and is detachably connected to the second connecting portion 23. By setting it in this way, the second main body 22 can be connected to the first shock absorber 121 to connect to the box body 11, which can reduce the risk of displacement of the second main body 22.

[0061] Optionally, the first shock absorber 121 may be an integral structure with the box body 11, wherein the first shock absorber 121 is formed by extending from the box body 11, so that the first shock absorber 121 has a certain structural strength and is conducive to assembly efficiency. Optionally, the first shock absorber 121 may be formed by extending from the bottom wall of the box body 11, and of course, the first shock absorber 121 may also be formed by extending from the bottom wall and side walls of the box body 11, wherein the bottom wall is a wall of the box body 11 arranged opposite to the box cover in the third direction Z, and the side wall is a wall connected between the box cover and the bottom wall.

[0062] In some examples, the first shock absorber 121 can also be provided separately from the box body 11 to facilitate processing and manufacturing, and the material of the first shock absorber 121 can be the same as that of the box body 11, or can be different to improve the flexibility of use. For example, the first shock absorber 121 can be provided as a sheet metal structure.

[0063] Please continue reading Figure 3 and Figure 4In some optional embodiments, the second main body 22 and the first shock absorber 121 are mutually engaged through the cooperation of the slot 31 and the protrusion 32, one of the slot 31 and the protrusion 32 is arranged on the second main body 22, and the other of the slot 31 and the protrusion 32 is arranged on the first shock absorber 121.

[0064] In a domain control battery pack provided in an embodiment of the present application, the detachable connection between the second main body 22 and the first shock absorber 121 can be set to a snap-on connection, which is convenient for assembly and disassembly and helps to improve maintenance efficiency.

[0065] In some optional embodiments, the first shock absorbing member 121 and the second main body portion 22 are arranged opposite to each other along the second direction Y, so as to facilitate the connection between the second main body portion 22 and the first shock absorbing member 121 .

[0066] Among them, one of the first shock absorber 121 and the second connecting part 23 is provided with a card slot 31, and the other is provided with a protrusion 32. By arranging the first shock absorber 121 and the second connecting part 23 relatively to each other along the second direction Y, when the second main body part 22 extends into the accommodating cavity 101 along the second direction Y, the second main body part 22 and the first shock absorber 121 can be connected by a card while contacting the two.

[0067] The first shock absorbing member 121 partially extends along the third direction Z so as to be connected and assembled with the second connecting portion 23 .

[0068] The specific assembly process of a domain control battery pack provided in the embodiment of the present application is to extend the second main body 22 from the opening 102 into the accommodating cavity 101 along the second direction Y, and the second main body 22 is connected with the first shock absorber 121 after contacting, and then the first main body 21 located outside the accommodating cavity 101 is connected with the box body 11 through fasteners, and the assembly of the domain control battery pack is completed. Accordingly, when the domain control battery pack needs to be disassembled, the fasteners between the first main body 21 and the box body 11 are removed, and the domain controller 20 is pulled out along the second direction Y to separate the first shock absorber 121 from the first shock absorber 121. There is no need to open the box cover, which is convenient for maintenance, saves maintenance time, and is also beneficial to protecting the safety of the battery assembly.

[0069] Optionally, in order to facilitate the installation and use of the domain controller battery pack as a whole, the opening 102 can avoid the bottom area of ​​the box body 11 and be set on the side of the box body 11, that is, one side of the box body 11 along the first direction X or one side along the second direction Y, so as to facilitate its disassembly and assembly in the working position, and at the same time facilitate bearing the weight of each functional module integrated on the domain controller 20.

[0070] Optionally, the opening 102 is located on one side of the box body 11 along the second direction Y, that is, is arranged on one side of the box body 11 along the length direction, which can make the domain control battery pack more compact and help reduce costs.

[0071] One of the slot 31 and the protrusion 32 is arranged on a side of the second main body 22 away from the first main body 21 along the second direction Y, and the other is arranged on the first shock absorber 121. Exemplarily, the second main body 22 has a protrusion 32, and the slot 31 is arranged on the first shock absorber 121. The protrusion 32 and the slot 31 are arranged opposite to each other in the first direction X. This arrangement is convenient for processing and manufacturing.

[0072] According to one aspect of the embodiment of the present application, the number of the card slots 31 is set to be more than two, and the more than two card slots 31 are spaced apart along the first direction X, and the number of the protrusions 32 is set to be more than two and are arranged one-to-one with the card slots 31.

[0073] The protrusions 32 are arranged one-to-one with the card slots 31, and the number of the card slots 31 can be set to two, three or even more. Correspondingly, the number of the protrusions 32 can also be set to two, three or even more. More than two card slots 31 are distributed at intervals along the first direction X. Correspondingly, more than two card slots 31 are distributed at intervals along the first direction X, and each card slot 31 has a protrusion 32 opposite to it along the first direction X.

[0074] By configuring in this manner, the connection strength between the second main body portion 22 and the first shock absorber 121 is increased, thereby helping to improve the structural strength of the domain control battery pack.

[0075] In some optional embodiments, the domain control battery pack further includes an elastic member, which is disposed on the slot wall of the slot 31 , and is squeezed between the protrusion 32 and the slot 31 .

[0076] Optionally, the elastic member may be configured as an annular structure, the specific structure of which matches the shape of the slot 31 so that it can be attached to the slot wall of the slot 31. Optionally, the elastic member may also be configured to include two or more elastic units distributed at circumferential intervals along the slot 31, each elastic unit being able to be attached to the slot wall of the slot 31, so that when the protrusion 32 is inserted into the slot wall, the elastic member can be squeezed and deformed by the protrusion 32 so that the protrusion 32 is confined within the slot 31.

[0077] Optionally, the elastic member includes a gasket, rubber, sponge or other structures.

[0078] A domain control battery pack provided in an embodiment of the present application provides an elastic member in the card slot 31, and enables the elastic member to be squeezed between the protrusion 32 and the card slot 31, so as to improve the connection strength between the protrusion 32 and the card slot 31. In addition, since the elastic member has elastic deformation ability, when the domain control battery pack needs to be disassembled, the domain controller 20 is pulled out to make the elastic member deform and restore its shape, so that the protrusion 32 is separated from the card slot 31, which is convenient for disassembly of the domain controller 20 and facilitates its maintenance and updating.

[0079] See also Figures 1 to 5 In some optional embodiments, the shock absorbing assembly 12 further includes a second shock absorbing member 122 connected to the first shock absorbing member 121 , and at least a portion of the second main body portion 22 is supported on the second shock absorbing member 122 .

[0080] Optionally, the first shock absorbing member 121 and the second shock absorbing member 122 may be an integrated structure for ease of processing and manufacturing. Of course, the two may also be provided separately.

[0081] The second shock absorber 122 is used to connect the first shock absorber 121 and to support the second main body 22. By configuring in this way, the second main body 22 can be connected and fixed to the first shock absorber 121, and can also be supported by the second shock absorber 122, thereby further reducing the risk of vibration of the domain controller 20 and further improving the connection strength and reliability of the domain controller battery pack.

[0082] The second main body 22 is supported on the second shock absorbing member 122 , which can be understood as the second main body 22 is disposed in contact with the second shock absorbing member 122 along the third direction Z, and the second shock absorbing member 122 provides support force for the second main body 22 .

[0083] The second main body 22 can be fully supported by the second shock absorber 122. At this time, the length dimension of the second shock absorber 122 along the second direction Y is the same as the length dimension of the second main body 22 along the second direction Y. Of course, the second main body 22 can also be partially supported by the second shock absorber 122.

[0084] Depend on Figure 5 As shown, in some optional embodiments, the second shock absorbing member 122 is bent and includes a first shock absorbing portion 1221, a second shock absorbing portion 1222, a third shock absorbing portion 1223 and a fourth shock absorbing portion 1224 which are connected in sequence, the first shock absorbing portion 1221 and the third shock absorbing portion 1223 both extend along the second direction Y and are spaced apart along the first direction X and the third direction Z, the third shock absorbing portion 1223 is abutted against the second main body portion 22, the first shock absorbing portion 1221 is connected to the first shock absorbing member 121 and has a gap with the second main body portion 22, and the third direction Z intersects with the first direction X and the second direction Y.

[0085] By configuring in this manner, stress concentration on the second shock absorber 122 can be avoided, and fracture failure thereof can be avoided, thereby ensuring the safety of the second shock absorber 122 .

[0086] Optionally, an arc-shaped connection structure is provided between the first shock absorbing part 1221 , the second shock absorbing part 1222 , the third shock absorbing part 1223 and the fourth shock absorbing part 1224 , so as to reduce stress concentration.

[0087] Optionally, the extension direction of the second shock absorbing portion 1222 and the fourth shock absorbing portion 1224 is inclined to the third direction Z, which is beneficial to reducing stress concentration.

[0088] In some optional embodiments, the shock absorbing assembly 12 further includes an elastic pad abutting between the second shock absorbing member 122 and the second main body portion 22 .

[0089] The elastic pad can buffer the force between the second shock absorbing member 122 and the second main body 22, thereby avoiding safety problems such as wear caused by excessive stress between the two.

[0090] Furthermore, by providing the elastic pad, when the second main body 22 extends into the accommodating cavity 101 along the second direction Y, the second main body 22 does not directly rub against the second shock absorber 122 but squeezes the elastic pad to ensure the safety of the second shock absorber 122 and the second main body 22 .

[0091] Specifically, the elastic pad is disposed between the third shock absorbing portion 1223 and the second main body portion 22 along the third direction Z. Optionally, the elastic pad may include any one of a rubber pad, a sponge, and a gasket.

[0092] See also Figure 1 In some optional embodiments, the domain control battery pack also includes a quick-plug assembly, which includes a quick socket 41 and a quick-plug part 42 of plug-in connection, one of the quick socket 41 and the quick-plug part 42 is connected to the domain controller 20 and is configured to be electrically connected to the functional module in the domain controller 20, and the other of the quick socket 41 and the quick-plug part 42 is connected to the shock absorbing assembly 12 and is configured to be electrically connected to the battery pack in the accommodating cavity 101.

[0093] A domain control battery pack provided in an embodiment of the present application also includes a quick-plug component, one of the quick socket 41 and the quick-plug part 42 included in the quick-plug component is arranged in the domain controller 20 and electrically connected to the functional module in the domain controller 20, and the other of the quick socket 41 and the quick-plug part 42 is arranged in the shock absorbing component 12 and electrically connected to the battery pack in the accommodating cavity 101. The quick socket 41 and the quick-plug part 42 are plug-connected, and the domain controller 20 can be moved along the second direction Y to achieve the connection and separation of the quick socket 41 and the quick-plug part 42, which is simple to operate and easy to maintain.

[0094] Furthermore, when the domain controller battery pack needs to be disassembled, the domain controller 20 is moved along the second direction Y away from the battery box 10 to separate the quick socket 41 from the quick plug part 42, thereby disconnecting the electrical connection between the functional module of the domain controller 20 and the battery assembly in the battery box 10, thereby ensuring safety and reliability.

[0095] Specifically, one of the quick socket 41 and the quick plug part 42 is disposed on the second body part 22 and electrically connected to the functional module on at least one of the first body part 21 and the second body part 22 , and the other of the quick socket 41 and the quick plug part 42 is connected to the first shock absorber 121 .

[0096] Exemplarily, the quick socket 41 is disposed on the second main body portion 22 , and the quick plug portion 42 is disposed on the first shock absorbing member 121 .

[0097] The quick socket 41 has a quick plug opening arranged along the second direction Y toward the quick plug part 42 , and the quick plug opening and the quick plug part 42 are arranged opposite to each other along the second direction Y, that is, the quick plug opening and the quick plug part 42 are arranged coaxially to ensure the effectiveness of the plug-in connection between the quick socket 41 and the quick plug part 42 .

[0098] Optionally, the orthographic projection of the quick-insertion portion 42 in the second direction Y falls into the quick-insertion port, and the quick-insertion port and the quick-insertion portion 42 can be coaxially arranged, or of course, can be non-coaxially arranged. When the quick-insertion portion 42 contacts the quick socket 41 along the second direction Y, the quick-insertion portion 42 can extend from the quick-insertion port and abut against the wall of the quick-insertion port. When one of the quick-insertion portion 42 and the quick socket 41 moves relative to the other, the quick-insertion portion 42 can move to be coaxially arranged with the quick-insertion port under the abutment effect of the wall to ensure the effectiveness of the connection between the quick-insertion portion 42 and the quick socket 41.

[0099] In some optional embodiments, the quick-insertion portion 42 is at least partially configured as a truncated cone structure, the truncated cone is arranged toward the quick socket 41 along the second direction Y, and the radial dimension of the truncated cone on one side close to the quick socket 41 along the second direction Y is smaller than the radial dimension of the other side.

[0100] By configuring in this manner, the friction between the quick-insertion portion 42 and the quick-insertion socket 41 is reduced, and positioning is facilitated, so that the quick-insertion portion 42 can be more accurately inserted into the quick-insertion socket 41 .

[0101] Optionally, the quick-insertion part 42 can be set as a truncated cone structure as a whole, that is, the radial dimension of the quick-insertion part 42 along the second direction Y from one side close to the quick socket 41 to the other side tends to increase. Of course, the quick-insertion part 42 can also be partially set as a truncated cone structure, and the truncated cone structure is set at a position close to the quick socket 41.

[0102] In some optional embodiments, the domain control battery pack further includes a bracket 43 , which is disposed on the shock absorbing assembly 12 , and one of the quick socket 41 and the quick plug part 42 is connected to the shock absorbing assembly 12 via the bracket 43 .

[0103] The bracket 43 can be set as a sheet metal bracket to improve the connection stability. The bracket 43 can be specifically set on the first shock absorbing member 121.

[0104] A domain control battery pack provided in an embodiment of the present application also includes a bracket 43 for connecting the quick socket 41 and the quick plug part 42 to ensure the stability of the connection between the two and the safety of the electrical connection between the two, thereby helping to improve the reliability of the domain control battery pack.

[0105] An embodiment of the present application also provides an electrical device, including a domain control battery pack as provided in the above embodiment.

[0106] The electric device provided in the embodiment of the present application includes a domain control battery pack that is beneficial for improving structural strength and reliability as provided in the above embodiments, and therefore, can be beneficial for improving the performance of the electric device.

[0107] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
