[0003] This application relates to the field of batteries, and in particular to a battery device and an electrical appliance. Background Technology

[0004] With the development of new energy technologies, battery devices are being used more and more widely, such as in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools.

[0005] The development of battery technology must take into account multiple design factors. For example, ensuring the connection and disassembly requirements between the battery device and the target component during the process of connecting the battery device to the target component is an important research direction in the battery field. Summary of the Invention

[0006] In view of the above problems, this application provides a battery device and an electrical device, wherein the battery device facilitates the installation and removal of the target component.

[0007] In a first aspect, this application provides a battery device, including a housing, a battery cell, and a locking component. The housing has a receiving cavity, in which the battery cell is disposed. The locking component is disposed in the housing and includes a base, an insert, a first locking member, and a second locking member. The base is connected to the housing, the insert is disposed within the base and connected to the base, the first locking member is movably disposed in the insert along its own axial direction, and the second locking member is connected to one end of the first locking member along its axial direction. The second locking member is configured to lock the first locking member to a target component or release the first locking member from the target component by rotation.

[0008] One embodiment of this application provides a battery device including a housing, battery cells, and locking components. The battery cells can provide or store electrical energy, and the housing can protect the battery cells. The corresponding locking components include a base, an insert, a first locking component, and a second locking component. The insert is disposed within the base. By movably mounting the first locking component within the insert and utilizing the cooperation of the second locking component with the first locking component, the battery device can be fixed to a target component. Furthermore, the structure for mounting the first and second locking components is configured as a separate base and insert structure. While meeting the connection requirements between the battery device and the target component, the base and insert can be manufactured separately and then connected, eliminating the need for simultaneous manufacturing and consistent performance. This facilitates cost reduction and lightweight design of the locking components.

[0009] In some embodiments, the stiffness of the insert is greater than the stiffness of the base.

[0010] The battery device provided in one embodiment of this application ensures the strength requirements of the insert that is movably engaged with the first locking member by making the stiffness of the insert greater than that of the base. At the same time, it eliminates the need to make the base and the insert from high-stiffness materials simultaneously, thereby reducing costs and ensuring the lightweight design requirements of the locking component.

[0011] In some embodiments, the insert is fixedly connected to the base.

[0012] One embodiment of the present application provides a battery device that, by fixing the insert to the base, ensures the stability of the connection between the two, thereby ensuring the stability of the connection between the battery device and the target component.

[0013] In some embodiments, the locking member further includes a guide groove and a guide pin. One of the insert and the first locking member is provided with a guide groove, and the other of the insert and the first locking member is provided with a guide pin. The guide pin extends into the guide groove, and the guide groove and the guide pin are used to limit the rotation range of the first locking member in its own circumferential direction.

[0014] The battery device provided in one embodiment of this application can fix the range of motion of the first locking member in the circumferential direction through the cooperation of the guide pin and the guide groove, and can conveniently and reliably make the first locking member and the second locking member relative to each other through the structure such as threads.

[0015] In some embodiments, the guide groove extends circumferentially with an extension angle greater than 90°, the guide groove has a first end and a second end in the circumferential direction, and there is a height difference between the first end and the second end in the axial direction, and the extension angle of the guide groove in the circumferential direction is greater than 90°.

[0016] The battery device provided in one embodiment of this application, by having a height difference between the first end and the second end, and the extension angle of the guide groove in the circumferential direction being greater than 90°, can ensure that the cooperation between the guide pin and the guide groove can fix the range of motion of the first locking member in the circumferential direction. At the same time, the above-mentioned arrangement can also enable the first locking member to have a large rotation range, increase the contact area between the end cap of the first locking member and the target component, and ensure the connection locking strength.

[0017] In some embodiments, a guide groove is disposed on the insert, a guide pin is disposed on the first locking member, and the insert is further provided with a mounting groove that communicates with the guide groove.

[0018] One embodiment of the battery device provided in this application, by setting a guide groove on the insert and setting a guide pin on the first locking member, can improve the strength of the groove wall of the guide groove by increasing the hardness of the insert, thereby improving wear resistance and facilitating cost reduction and lightweight design of the locking component. The mounting groove facilitates the insertion of the first locking member carrying the guide pin into the insert, and then allows the guide pin to enter the guide groove and rotate with the first locking member relative to the insert, thereby realizing the adjustment of the position of the first locking member in the insert and its cooperation with the second locking member, satisfying the locking or unlocking between the battery device and the target component.

[0019] In some embodiments, a sealing element is provided in the mounting groove, the sealing element being matched with the shape of the guide groove and detachably connected to the insert.

[0020] One embodiment of this application provides a battery device in which a sealing member is provided in the mounting groove. The sealing member matches the shape of the guide groove and is detachably connected to the insert, so that when the guide pin is installed into the guide groove, the mounting groove can be sealed, effectively preventing the first locking member and the guide pin from rotating off track and improving the reliability of the battery device.

[0021] In some embodiments, the insert has a first through hole extending axially, the first locking member extends at least partially into the first through hole, the mounting groove communicates with the first through hole, and the side of the sealing member facing the first locking member is an arc-shaped surface.

[0022] In one embodiment of this application, a battery device is provided. Through the above-described configuration, after the first locking member carrying the guide pin is inserted into the insert, the sealing member can adapt to the shape of the first locking member, smoothly enter the mounting groove, and avoid interference with the first locking member. This helps to prevent the first locking member and the guide pin from rotating off track, thereby improving the reliability of the battery device.

[0023] In some embodiments, along the axial direction, the mounting groove is recessed from one end of the insert toward the other end, and a fastener is provided in the mounting groove. The fastener is detachably connected to the insert, and the orthogonal projection of the fastener in the axial direction covers part of the sealing member.

[0024] The battery device provided in one embodiment of this application, through the above-described configuration, enables the sealing member to be fixed in the mounting groove by fasteners after it is installed, thereby ensuring the requirement to prevent the guide pin from derailing.

[0025] In some embodiments, the number of guide grooves is two or more, the two or more guide grooves are distributed at intervals along the circumference, and each guide groove is provided with a guide pin.

[0026] One embodiment of the present application provides a battery device that, by having two or more guide grooves, facilitates the stability of the fit between the first locking member and the insert, thereby ensuring the reliability of the connection between the battery device and the target component.

[0027] In some embodiments, at least one of the insert and the base is provided with a first limiting portion, which restricts the insert from rotating relative to the base.

[0028] One embodiment of this application provides a battery device that, by setting a first limiting part and restricting the rotation of the insert relative to the base, ensures the connection strength and integrity of the insert and the base after assembly and connection, thereby ensuring the reliability of the connection between the battery device and the target component.

[0029] In some embodiments, the first limiting portion includes a first limiting surface disposed on the base and a second limiting surface disposed on the insert, wherein the first limiting surface and the second limiting surface have matching shapes and fit together.

[0030] The battery device provided in one embodiment of this application, by having the first limiting part include a first limiting surface disposed on the base and a second limiting surface disposed on the insert, can achieve the anti-rotation requirement between the insert and the base through the cooperation of the first limiting surface and the second limiting surface, and the structure is conducive to processing, forming and assembly.

[0031] In some embodiments, the locking member further includes a dust cover disposed at one axial end of the insert, the dust cover surrounding the first locking member, and the dust cover covering the gap between the first locking member and the insert.

[0032] One embodiment of the present application provides a battery device that, by providing a dust cover, facilitates the sealing of the gap between the first locking member and the insert, preventing impurities and the like from entering the insert and affecting the reliability of the locking mechanism.

[0033] In some embodiments, the insert has a second limiting portion on one side of the axial direction, and the second limiting portion abuts against the base along the axial direction.

[0034] One embodiment of the present application provides a battery device that, by providing a second limiting part on one side of the insert in the axial direction, can use the second limiting part to provide a limit in the axial direction, thereby limiting the relative position of the insert and the base in the axial direction and ensuring the reliability of the connection between the battery device and the target component.

[0035] In some embodiments, a first locking member is inserted into an insert and protrudes axially from the insert, and a second locking member is detachably connected to the portion of the first locking member that protrudes from the insert.

[0036] The battery device provided in one embodiment of this application, through the above-described configuration, facilitates the disassembly and assembly connection between the second locking member and the first lock, thereby facilitating the disassembly and assembly requirements between the device and the target component.

[0037] In some embodiments, the locking member further includes a stop member connected to the base, the stop member being disposed on the side of the second locking member axially opposite to the insert member, and the orthogonal projection of the stop member in the axial direction covering the second locking member.

[0038] One embodiment of the present application provides a battery device in which a stop member is provided so that when the second locking member is unlocked and separated from the first locking member, the stop member can provide axial limit to the second locking member, thereby preventing the second locking member from separating from the base, preventing the loss of parts, and improving the overall disassembly and assembly efficiency of the battery device.

[0062] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0063] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0064] Battery devices typically need to be connected to target components of a power-consuming entity during use to provide electrical energy. In related technologies, the structure used for connection between the battery device and the target component requires high overall strength, resulting in a higher overall cost for the battery device.

[0065] Based on this, this application proposes a battery device, in which a corresponding locking component includes a base, an insert, a first locking component, and a second locking component. The insert is disposed within the base. By allowing the first locking component to be movably disposed within the insert, and facilitating the engagement of the second locking component with the first locking component, the battery device can be fixed to the target component. Furthermore, the structure for mounting the first and second locking components is configured as a separate base and insert structure. While meeting the connection requirements between the battery device and the target component, the base and insert can be manufactured separately and then connected, eliminating the need to manufacture them simultaneously and maintain consistent performance. This facilitates cost reduction and lightweight design of the locking component.

[0066] Electrical equipment can include vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools, etc. Electrical devices can also be energy storage devices, which can be used, but are not limited to, in small-scale, medium-scale, and large-scale industrial and commercial applications, photovoltaic-storage charging stations, and small and medium-sized microgrids, as well as in wind-solar-storage power stations, grid-connected energy storage power stations, and large-scale microgrid power station scenarios, for the purpose of storing and releasing electrical energy.

[0067] It should be understood that the technical solutions described in the embodiments of this application are not limited to the above-mentioned electrical equipment, but can also be applied to all electrical devices that use battery devices. However, for the sake of brevity, the following embodiments are all described using electric vehicles as examples.

[0068] For example, as shown in Figure 1, which is a structural schematic diagram of a vehicle 1 according to one embodiment of this application, vehicle 1 can be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The interior of vehicle 1 can be equipped with a motor 400, a controller 300, and a battery device 100. The controller 300 is used to control the battery device 100 to supply power to the motor 400. For example, the battery device 100 can be located at the bottom, front, or rear of vehicle 1. The battery device 100 can be used to power vehicle 1. For example, the battery device 100 can serve as the operating power source for vehicle 1, for example, for the electrical system of vehicle 1, such as for the power requirements of vehicle 1's starting, navigation, and operation. In another embodiment of this application, the battery device 100 can not only serve as the operating power source for vehicle 1, but also as the driving power source for vehicle 1, replacing or partially replacing gasoline or natural gas to provide driving power for vehicle 1.

[0069] To meet different power demands, the battery device 100 may include multiple battery cells 20, which may be connected in series, parallel, or a combination thereof. The battery device 100 may also be referred to as a battery pack.

[0070] For example, as shown in Figures 2 to 7, Figure 2 is a structural schematic diagram of a battery device 100 provided in an embodiment of this application; Figure 3 is a top view schematic diagram of a battery device 100 provided in an embodiment of this application; Figure 4 is a structural schematic diagram of a locking member 30 provided in an embodiment of this application; Figure 5 is a cross-sectional view of a locking member 30 provided in an embodiment of this application; Figure 6 is a partial top view of a locking member 30 and a target member 500 provided in an embodiment of this application; and Figure 7 is a cross-sectional view along the AA direction in Figure 6.

[0071] A battery device 100 according to one embodiment of this application may include a housing 10, a battery cell 20, and a locking member 30. Optionally, the housing 10 has a receiving cavity, the battery cell 20 is disposed in the receiving cavity, and the locking member 30 is disposed in the housing 10. Optionally, the locking member 30 includes a base 31, an insert 32, a first locking member 33, and a second locking member 34. The base 31 is connected to the housing 10, the insert 32 is disposed within the base 31 and connected to the base 31, the first locking member 33 is movably disposed in the insert 32 along its own axial direction X, and the second locking member 34 is connected to one end of the first locking member 33 along the axial direction X. Optionally, the second locking member 34 is configured to lock the first locking member 33 to a target component 500 or release the first locking member 33 from the target component 500 by rotation.

[0072] The housing 10 can be a simple three-dimensional structure such as a cuboid, cylinder, or sphere, or it can be a complex three-dimensional structure composed of simple three-dimensional structures such as cuboids, cylinders, or spheres. This application embodiment does not limit this. The material of the housing 10 can be an alloy material such as aluminum alloy or iron alloy, or a polymer material such as polycarbonate or polyisocyanurate foam, or a composite material such as glass fiber and epoxy resin. This application embodiment also does not limit this.

[0073] The housing 10 is used to accommodate the battery cell 20, and the housing 10 can have various structures. In some embodiments, the housing 10 may include a first housing portion 11 and a second housing portion 12, which overlap each other, and together define a receiving space for accommodating the battery cell 20. The second housing portion 12 may be a hollow structure with one end open, and the first housing portion 11 may be a plate-like structure, with the first housing portion 11 covering the open side of the second housing portion 12 to form a housing 10 with a receiving space; alternatively, both the first housing portion 11 and the second housing portion 12 may be hollow structures with one side open, with the open side of the first housing portion 11 covering the open side of the second housing portion 12 to form a housing 10 with a receiving space. Of course, the first housing portion 11 and the second housing portion 12 can have various shapes, such as cylinders, cuboids, etc.

[0074] To improve the sealing performance after the first housing part 11 and the second housing part 12 are connected, a sealing element, such as sealant or sealing ring, can also be provided between the first housing part 11 and the second housing part 12.

[0075] Assuming that the first box part 11 covers the top of the second box part 12, the first box part 11 can also be called the upper box cover, and the second box part 12 can also be called the lower box 10.

[0076] In the battery device 100, there can be one or more battery cells 20. If there are multiple battery cells 20, they can be connected in series, in parallel, or in a mixed configuration. A mixed configuration means that multiple battery cells 20 are connected in both series and parallel. Multiple battery cells 20 can be directly connected in series, in parallel, or in a mixed configuration, and then the whole assembly of multiple battery cells 20 is housed in the housing 10. Alternatively, multiple battery cells 20 can first be connected in series, in parallel, or in a mixed configuration to form a battery module 200, and then multiple battery modules 200 can be connected in series, in parallel, or in a mixed configuration to form a whole assembly, which is then housed in the housing 10.

[0077] In some embodiments, as shown in FIG2, there are multiple battery cells 20, which are first connected in series, parallel, or mixed to form a battery module 200. The multiple battery modules 200 are then connected in series, parallel, or mixed to form a whole and housed in the housing 10.

[0078] Multiple battery cells 20 in the battery module 200 can be electrically connected through a busbar component to achieve parallel, series, or mixed connection of multiple battery cells 20 in the battery module 200.

[0079] In this application, the battery cell 20 may include lithium-ion battery cell 20, sodium-ion battery cell 20, or magnesium-ion battery cell 20, etc., and the embodiments of this application are not limited to this. The battery cell 20 may be cylindrical, flat, cuboid, or other shapes, and the embodiments of this application are not limited to this either. Battery cells 20 are generally divided into three types according to their packaging method: cylindrical battery cells 20, cuboid battery cells 20, and pouch battery cells 20, and the embodiments of this application are not limited to this either. However, for the sake of brevity, the following embodiments will all use a cuboid battery cell 20 as an example for description.

[0080] The locking component 30 can be used to lock the housing 10 onto the target component 500, which can be the vehicle 1, such as a door sill or similar structure. Of course, the target component 500 can also be a ship or similar vessel.

[0081] In some embodiments, the base 31 is connected to the housing 10. The base 31 and the housing 10 can be fixedly connected, such as by welding, bonding, interference fit, etc. Of course, the base 31 and the housing 10 can also be fixedly connected by a detachable connection, such as by fasteners such as bolts and screws. The base 31 can be used to install the support insert 32.

[0082] In some embodiments, the base 31 may have an inner cavity, and the insert 32 is installed into the inner cavity of the base 31, such that the insert 32 can be disposed within the base 31.

[0083] In some embodiments, the insert 32 and the base 31 can be formed separately and processed independently, and then assembled so that the insert 32 is disposed in the base 31.

[0084] In some embodiments, the insert 32 can be fixedly connected to the base 31, for example, by means of interference fit or welding. Of course, in some embodiments, the insert 32 can also be detachably connected to the base 31, for example, by means of fasteners such as bolts or screws, so that the base 31 and the insert 32 can be detachably connected.

[0085] In some embodiments, the base 31 and the insert 32 may be made of the same material. For example, the base 31 and the insert 32 may be made of the same metallic material, and the base 31 and the insert 32 may be detachably connected. Of course, in some embodiments, the base 31 and the insert 32 may be made of different materials; for example, the hardness of the insert 32 may be greater than the hardness of the base 31. The base 31 and the insert 32 may be fixedly connected or detachably connected.

[0086] In some embodiments, the first locking member 33 is inserted into and movably connected to the insert 32 along its own axial direction X. Optionally, the insert 32 may be provided with a first through hole 322 extending along the axial direction X. Optionally, the insert 32 may be provided with a guide structure that cooperates with the first locking member 33.

[0087] In some embodiments, the first locking member 33 has an end cap 33b at one end in the axial direction X and the other end is used to cooperate with the second locking member 34.

[0088] In some embodiments, the second locking member 34 and the first locking member 33 can be connected by a threaded connection, a snap-fit ​​connection, or other structural forms. This allows the second locking member 34 to adjust the relative position of the first locking member 33 and the insert 32 in the axial direction X by means of its own rotation.

[0089] One embodiment of this application provides a battery device 100, including a housing 10, a battery cell 20, and a locking component 30. The battery cell 20 can provide or store electrical energy, and the housing 10 can protect the battery cell 20. The correspondingly provided locking component 30 includes a base 31, an insert 32, a first locking component 33, and a second locking component 34. The insert 32 is disposed within the base 31. By movably disposing of the first locking component 33 within the insert 32 and by utilizing the cooperation of the second locking component 34 with the first locking component 33, the battery device 100 can be fixed to the target component 500. Furthermore, the structure for mounting the first locking component 33 and the second locking component 34 is configured as a structure including a separate base 31 and insert 32. While meeting the connection requirements between the battery device 100 and the target component 500, the base 31 and insert 32 can be manufactured separately and then connected, eliminating the need to manufacture them simultaneously and maintain consistent performance. This facilitates cost reduction and lightweight design of the locking component 30.

[0090] In some alternative embodiments, the rigidity of the insert 32 in the battery device 100 provided in one embodiment of this application is greater than the rigidity of the base 31.

[0091] Optionally, the stiffness of the material used to make the insert 32 can be greater than the stiffness of the material used to make the base 31. For example, the base 31 can be made of aluminum, and the insert 32 can be made of steel. Of course, in some embodiments, the insert 32 can also be made of other materials such as stainless steel.

[0092] The battery device 100 provided in one embodiment of this application ensures the strength requirements of the insert 32, which is movable and cooperates with the first locking member 33, by making the stiffness of the insert 32 greater than that of the base 31. At the same time, it eliminates the need to make the base 31 and the insert 32 simultaneously using high-stiffness materials, thereby reducing costs and ensuring the lightweight design requirements of the locking member 30.

[0093] In some alternative embodiments, the battery device 100 provided in one embodiment of this application has an insert 32 fixedly connected to a base 31.

[0094] The insert 32 and the base 31 can be fixedly connected by an interference fit. Of course, in some embodiments, they can also be fixedly connected by welding or bonding.

[0095] The battery device 100 provided in one embodiment of this application can ensure the stability of the connection between the insert 32 and the base 31 by fixing the insert 32 to the base 31, thereby ensuring the stability of the connection between the battery device 100 and the target component 500.

[0096] As shown in Figures 8 and 9, Figure 8 is a partial structural schematic diagram of the locking component 30 provided in an embodiment of this application; Figure 9 is a structural schematic diagram of the first locking part provided in an embodiment of this application.

[0097] In some alternative embodiments, the battery device 100 provided in one embodiment of this application includes a locking member 30 that further includes a guide groove 321 and a guide pin 331. The guide groove 321 is provided on one of the insert 32 and the first locking member 33, and the guide pin 331 is provided on the other of the insert 32 and the first locking member 33. The guide pin 331 extends into the guide groove 321. The guide groove 321 and the guide pin 331 are used to limit the rotation range of the first locking member 33 in its own circumferential Y direction.

[0098] The number of guide grooves 321 can be one, or more than two. The number of guide grooves 321 can be the same as the number of guide pins 331 and can be set one-to-one.

[0099] Optionally, the guide pin 331 can be provided on the base 31 or the first locking member 33, and can be detachably connected, that is, a hole is provided in the base 31 or the first locking member 33, and the guide pin 331 is provided in the hole, so as to facilitate processing and connection.

[0100] Optionally, the specific rotation range of the first locking member 33 in the circumferential Y direction can be adjusted by adjusting the angle through which the guide groove 321 extends in the circumferential Y direction.

[0101] Specifically, the first locking member 33 and the second locking member 34 can be threadedly connected. By limiting the rotation angle of the first locking member 33, it can be limited after rotating through a preset angle and kept in a fixed position in the circumferential Y direction. Thus, the second locking member 34 can be rotated and the first locking member 33 and the second locking member 34 can be moved towards each other or away from each other in the axial X direction through the thread between them, thereby locking and unlocking the target component 500.

[0102] The battery device 100 provided in one embodiment of this application can fix the range of motion of the first locking member 33 in the circumferential Y direction through the cooperation of the guide pin 331 and the guide groove 321, and can conveniently and reliably generate relative displacement between the first locking member 33 and the second locking member 34 through the structure of threads or the like.

[0103] Referring again to Figures 8 and 9, in some optional embodiments, the battery device 100 provided in one embodiment of this application has a guide groove 321 extending along the circumferential direction Y. The guide groove 321 has a first end 3211 and a second end 3212 in the circumferential direction Y. Along the axial direction X, there is a height difference between the first end 3211 and the second end 3212. The extension angle of the guide groove 321 along the circumferential direction Y is greater than 90°.

[0104] The extension angle of the guide groove 321 along the circumferential Y direction is greater than 90°, which can be understood as the angle between the orthogonal projection of the first end 3211 and the second end 3212 of the guide in the circumferential Y direction and the line connecting the center of the first locking member 33 is greater than 90°.

[0105] Taking the example that the height of the second end 3212 is higher than that of the first end 3211 in the axial direction X, the height of the guide groove 321 gradually increases along the axial direction X from the first end 3211 to the second end 3212.

[0106] The battery device 100 provided in one embodiment of this application, by having a height difference between the first end 3211 and the second end 3212, and the extension angle of the guide groove 321 in the circumferential Y direction being greater than 90°, can ensure that the cooperation between the guide pin 331 and the guide groove 321 can fix the range of motion of the first locking member 33 in the circumferential Y direction. At the same time, the above-mentioned arrangement can also enable the first locking member 33 to have a large rotation range, increase the contact area between the end cap 33b of the first locking member 33 and the target component 500, and ensure the connection locking strength.

[0107] As shown in Figure 10, Figure 10 is a structural schematic diagram of an insert provided in one embodiment of this application. In some embodiments, a guide groove 321 is disposed on the insert 32, a guide pin 331 is disposed on the first locking member 33, and an installation groove 323 is provided on the insert 32, the installation groove 323 communicating with the guide groove 321.

[0108] Optionally, the number of mounting slots 323 provided on the insert 32 can be equal to the number of guide slots 321 and set one-to-one, so that the guide pin 331 provided on the first locking member 33 can enter the guide slot 321 through the mounting slot 323.

[0109] One embodiment of this application provides a battery device 100, which, by providing an mounting groove 323, facilitates the insertion of a first locking member 33 carrying a guide pin 331 into an insert 32. Then, the guide pin 331 can enter the guide groove 321 and rotate with the first locking member 33 relative to the insert 32, thereby adjusting the position of the first locking member 33 within the insert 32 and cooperating with the second locking member 34, which is beneficial for satisfying the locking or unlocking between the battery device 100 and the target component 500.

[0110] In some alternative embodiments, a battery device 100 provided in one embodiment of this application has a sealing member 35 disposed in the mounting groove 323. The sealing member 35 matches the shape of the guide groove 321 and is detachably connected to the insert 32.

[0111] Matching the shape of the sealing element 35 with the shape of the guide groove 321 can be understood as follows: in the axial direction X, the cross-sectional shape of the sealing element 35 can be consistent with the cross-sectional shape of the guide groove 321, and the height dimension of the sealing element 35 in the axial direction X can be consistent with the depth of the guide groove 321. Of course, it can also be less than or less than the depth of the guide groove 321.

[0112] By providing a sealing member 35 in the mounting groove 323, the sealing member 35 matches the shape of the guide groove 321 and is detachably connected to the insert 32, so that when the guide pin 331 is installed into the guide groove 321, the mounting groove 323 can be sealed, effectively preventing the first locking member 33 and the guide pin 331 from rotating off track, and improving the reliability of the battery device 100.

[0113] Referring to Figure 10, in some optional embodiments, the battery device 100 provided in one embodiment of this application has a first through hole 322 extending along the axial direction X in the insert 32, a first locking member 33 extending at least partially into the first through hole 322, a mounting groove 323 communicating with the first through hole 322, and a sealing member 35 having an arc-shaped surface 351 on the side facing the first locking member 33.

[0114] The side of the sealing member 35 facing the first locking member 33 can be understood as the surface of the sealing member 35 facing the first locking member 33 along the radial direction of the first through hole 322.

[0115] In one embodiment of this application, a battery device 100 is provided. Through the above-described configuration, after the first locking member 33 carrying the guide pin 331 is inserted into the insert 32, the sealing member 35 can adapt to the shape of the first locking member 33, smoothly enter the mounting groove 323, and avoid interference with the first locking member 33. This helps to prevent the first locking member 33 and the guide pin 331 from rotating off track, thereby improving the reliability of the battery device 100.

[0116] In some alternative embodiments, the radius of the arcuate surface 351 of the sealing member 35 can be made equal to the radial dimension of the first through hole 322. In this way, the arcuate surface 351 can be adapted to the radial dimension of the side wall of the first through hole 322 and form a complete circle, ensuring the stability of the first locking member 33 within the first through hole 322 and improving the locking stability.

[0117] As shown in Figure 11, which is a partial structural schematic diagram of the locking component 30 provided in another embodiment of this application, in some optional embodiments, the mounting groove 323 is recessed from one end of the insert 32 along the axial direction X towards the other end.

[0122] The number of guide grooves 321 can be two, three, or more. Two or more guide grooves 321 can be distributed at intervals in the circumferential Y direction of the first locking member 33, and can be spaced out and evenly distributed.

[0123] One embodiment of the present application provides a battery device 100, which, by having two or more guide grooves 321, facilitates the stability of the engagement between the first locking member 33 and the insert member 32, thereby ensuring the reliability of the connection between the battery device 100 and the target component 500.
