Description

Battery devices and electrical appliances

[0001] This application claims priority to Chinese Patent Application No. 202411718443.4, filed with the State Intellectual Property Office of China on November 27, 2024, entitled "Battery Device and Power Consumption Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of battery technology, and in particular relates to a battery device and an electrical device. Background Technology

[0003] With the rise of new energy equipment, represented by new energy vehicles, battery devices have become a key power source. Battery devices include battery cell modules composed of multiple battery cells. Battery cell modules need to input and output current, which can be achieved by connecting the output terminal to the battery plate.

[0004] Long-term exposure of the output terminals may lead to the accumulation of dust and other foreign matter, affecting conductivity and lifespan. Therefore, a structure is needed to cover the output terminals.

[0005] In related technologies, the structure covering the output terminal is set as an openable cover. If the cover is opened only slightly, it will close again under gravity, which is not conducive to the operation of the output terminal. Furthermore, since the cover is close to the battery cell assembly, if it is opened too wide, the cover may flip over and touch the battery cell assembly on one side, causing damage to the battery cell assembly. Summary of the Invention

[0006] In view of the above problems, this application provides a battery device and an electrical device, which aims to solve the technical problem that it is difficult to operate the output terminal when the cover is flipped at a small angle or that it is easy to flip and touch the battery cell assembly when the flipping angle is large. Technical solutions

[0007] To address the aforementioned problems, in a first aspect, embodiments of this application provide a battery device, comprising:

[0008] A battery cell assembly, electrically connected to conductive components for current input and output;

[0009] Output terminals are used for electrical connection to conductive components; and

[0010] A housing, mounted on one side of the battery cell assembly, is used to house the output terminal. The housing includes a cover configured to rotate about a preset axis to expose or cover the output terminal and to hover in the rotation path. The advantage of this embodiment is that by setting the cover to be able to hover, the cover will not close under gravity after being opened, nor will it flip backward and touch the battery cell assembly or other components. This ensures normal operation of the output terminal and protects the battery cell assembly and other components from damage.

[0011] In one embodiment of the first aspect, the housing further includes a base, the output terminal is fixed to the base, and the housing cover is rotatably connected to the base and used to cover the base. The advantage of this embodiment is that it provides a base, which is equivalent to providing an installation position for the output terminal, and the base, together with the housing cover, forms an accommodating space. Furthermore, the base can be fixed to one side of the battery cell assembly to achieve positioning of the base and the output terminal on the base.

[0012] In one embodiment of the first aspect, one of the base and the cover includes a sleeve structure, and the other includes a shaft structure. The sleeve structure and the shaft structure are interlocked, and the preset axis is the axis of the shaft structure. This embodiment provides a form for realizing the rotation of the cover relative to the base. It has a simple structure, is easy to operate, can rotate stably, and has good reliability.

[0013] In one embodiment of the first aspect, one of the base and the cover has an elastic protrusion, and the other has a groove for accommodating the protrusion. When the cover rotates, the protrusion can be engaged into the groove. The structure provided in this embodiment realizes a means for the cover to be suspended relative to the base. It can be suspended when the cover rotates, and the implementation method is simple and very convenient to operate.

[0014] In one embodiment of the first aspect, the groove is disposed on the outer surface of the sleeve structure, and the protrusion abuts against the outer surface of the sleeve structure when the cover rotates. In this embodiment, the groove is disposed on the outer surface of the sleeve structure. This arrangement allows the outer perimeter of the sleeve structure to be used as a reference, facilitating accurate setting of the hovering position. The groove can be disposed at a specific position on the circumference of the outer surface of the sleeve structure, enabling the cover to hover at a precise preset position. Furthermore, when rotating, the protrusion abuts against the outer surface of the sleeve structure, allowing it to accurately engage with the groove upon arrival.

[0015] In one embodiment of the first aspect, the sleeve structure is disposed on the base, and the protrusion is a spring piece protruding from the shell cover. The advantage of this embodiment is that the rotation of the shaft structure is more stable and effective than that of the sleeve structure, and it is also easier to design and manufacture. Therefore, by placing the sleeve structure on the base and using a spring piece for the protrusion, the protrusion can maintain a certain compressive force on the surface of the sleeve structure, thereby smoothly engaging it into the groove.

[0016] In one embodiment of the first aspect, a raised portion is formed on the outer surface of the sleeve structure, and a groove is formed at the raised portion, the extension direction of the groove being parallel to the preset axis. This embodiment avoids the drawback of the protrusion generating a resisting force with the surface of the sleeve structure, thus affecting the rotation effect, making the rotation smoother. Furthermore, the higher position of the groove also makes the locking force of the protrusion greater, which can effectively limit the rotation of the cover.

[0017] In one embodiment of the first aspect, the sleeve structure includes two sleeve structures, which are symmetrically arranged and spaced apart, and the shaft structure is inserted into the two sleeve structures respectively.

[0018] The advantage of this embodiment is that the selection of two sleeve structures makes it easier to assemble with the shaft structure, and the symmetrical arrangement of the two sleeve structures also makes the cover more stable when rotating, and will not cause any offset or sway in other directions.

[0019] In one embodiment of the first aspect, the shaft structure is an integral structure, with both ends of the shaft structure inserted into the sleeve structures from opposite sides. This embodiment provides an integral shaft structure, meaning the shaft structure is a single, continuous shaft with both ends inserted into the sleeve structures on either side, specifically from opposite sides of the two sleeve structures to complete the connection. This embodiment is a specific form of connecting the shaft structure and the sleeve structure, which can achieve a better and more stable rotation effect after connection.

[0020] In one embodiment of the first aspect, the shaft structure comprises two separate shafts, each inserted into a sleeve structure from opposite sides. This embodiment provides another implementation of the connection between the shaft structure and the sleeve structure. Not only are the two sleeve structures spaced apart, but the two shafts are not integral; they are inserted separately. This simplifies the length of the shaft structure. Using two shorter shafts inserted separately does not affect the stability and balance of rotation, and makes the structure simpler.

[0021] In one embodiment of the first aspect, the sleeve structure has an axially oriented notch, which is used to avoid the protrusion when the shaft structure is inserted into the sleeve structure. The notch in this embodiment ensures smooth insertion of the shaft structure and avoids interference from the protrusion.

[0022] In one embodiment of the first aspect, the base is provided with a locking block, and the cover is provided with a latch. When the cover closes the base, the locking block engages with the latch to lock the cover. When the cover is closed, the locking block engages with the latch, and the shape of the locking block itself can be locked at the side of the latch to prevent it from coming out.

[0023] In one embodiment of the first aspect, the cover includes a tongue plate, which is connected to the main body of the cover via one side edge, and the latch is disposed on the tongue plate. In this embodiment, the latch is disposed on the tongue plate, so that when it is necessary to open the cover, the tongue plate can be moved to disengage the latch from the latch, thus easily opening the cover. This design improves the ease of opening the cover.

[0024] In one embodiment of the first aspect, the base is provided with a stepped structure, and the cover is provided with an overlapping portion adapted to the shape of the stepped structure. When the cover is closed on the base, the overlapping portion overlaps the stepped structure. In this way, when the cover is closed on the base, the stepped surfaces mutually limit and abut against each other, so that the cover can maintain good stability when closed.

[0025] In one embodiment of the first aspect, the free end of the tongue plate is bent away from the base to form a warped portion. This facilitates the movement of the tongue plate, and the warped portion can be operated while the tongue plate is being moved.

[0026] In one embodiment of the first aspect, the base has a planar portion, and the output terminal is disposed on the planar portion. Therefore, this embodiment provides a base with a planar portion, and the output terminal is vertically disposed on the planar portion. This ensures that there are no obstructions or interference from other structures around it, making it easy to connect the output terminal to conductive components. Furthermore, when a switch or similar component is connected to the output terminal, it can be placed on the planar portion. The large contact area between the planar portion and the switch is beneficial to the stability of the switch, i.e., to the stability of the relative position between the switch and the output terminal.

[0027] In one embodiment of the first aspect, the base has a connecting portion for connecting to one side of the battery cell assembly, the connecting portion being located outside the coverage area of ​​the casing. The advantage of this embodiment is that the connection via the connecting portion is more stable than a conventional bolt connection because the connecting portion has a specific shape that allows it to fit and connect with the structure of the side of the battery cell assembly, effectively increasing the contact area of ​​the connection and thus improving stability.

[0028] In one embodiment of the first aspect, the side of the housing facing the battery cell assembly is open to allow the conductive element to connect to the output terminal. This embodiment facilitates the connection between the conductive element and the output terminal.

[0029] Secondly, this application also provides an electrical device, including the battery device described in any of the embodiments. This improves the stability of the electrical device in use.

[0050] 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 used 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 application areas, the market demand is also constantly increasing.

[0051] A battery device may include multiple battery cells, which are arranged to form multiple battery cell assemblies. Each battery cell assembly can be called a battery module. The electrode terminals of multiple battery cells within the same battery cell assembly are connected in series or parallel. Different battery cell assemblies can also be interconnected. To enable the battery device to output power, output terminals can be provided at the battery cell assemblies. These output terminals are internally connected to the battery cell assemblies and externally connected to electrical devices or charging equipment.

[0052] If the output terminals are exposed for extended periods, they may become covered by dust and other contaminants, affecting conductivity and lifespan. Therefore, a structure is needed to cover the output terminals.

[0053] Since the battery cells are electrically connected to the output terminals, specifically via conductive components such as electrodes, the structure covering the output terminals is usually designed to be openable, i.e., an openable cover. If the cover is opened only slightly, it will close again under gravity, which is not conducive to operating the output terminals. Furthermore, since the cover is close to the battery cells, if it is opened too wide, the cover may flip over and touch one of the battery cells, causing damage.

[0054] Based on the above considerations, this application provides a battery device that aims to solve the above problems to a certain extent.

[0055] This application also provides an electrical device having the battery device provided in the above embodiments, that is, an electrical device that uses the battery device as a power source.

[0056] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connection via a busbar. Mixed connection refers to a combination of series and parallel connections.

[0057] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0058] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0059] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0060] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0061] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0062] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0063] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0064] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

Vehicles can be gasoline-powered cars, natural gas-powered cars, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles. Spacecraft include airplanes, rockets, space shuttles, and spacecraft. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers.

[0066] The battery device disclosed in this application can be used, but is not limited to, in electrical devices such as vehicles, ships, or aircraft. Electrical devices can use power systems equipped with the battery device disclosed in this application, which helps improve the reliability of the electrical devices.

[0067] For ease of explanation, the following embodiments use a vehicle as an example of the electrical device provided in the embodiments of this application.

[0068] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 100 is installed inside the vehicle 1000, and the battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0069] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0070] Please refer to Figures 2-9. An embodiment of this application provides a battery device 100, including a battery cell assembly 10, an output terminal 11, and a housing 12. The battery cell assembly 10 is electrically connected to conductive elements for current input and output; the output terminal 11 is used for electrical connection to the conductive elements; the housing 12 is mounted on one side of the battery cell assembly 10 and is used to house the output terminal 11. The housing 12 includes a cover 13, which is configured to rotate about a preset axis to expose or cover the output terminal 11 and can be suspended in the rotation path. The battery device 100 may also include a housing 29, within which the battery cell assembly 10, the output terminal 11, and the housing 12 can be disposed.

[0071] Specifically, as shown in Figures 3 and 4, the battery cell assembly 10 includes multiple battery cells 27 arranged along a predetermined direction. The battery cell assembly 10 also includes two end plates 28, which are respectively disposed at both ends of the arrangement direction of the multiple battery cells 27 to fix a row of battery cells 27. The multiple battery cells 27 are connected in series, parallel, or a combination of series and parallel to form a module. This module has a set of output terminals 11, namely a positive output terminal and a negative output terminal. It can be understood that the term "output terminal 11" is used when the battery device 100 is in a discharged state, and is referred to as "output terminal 11" for ease of description. When the battery device 100 is in a charging state, the "output terminal 11" is used for current input. In some cases, the output terminal 11 is located at the end of the battery cell assembly 10. The battery cell assembly 10 has conductive elements that electrically connect each battery cell 27, and these conductive elements are connected to the output terminals 11. The conductive elements can be electrodes, specifically copper electrodes. The output terminal 11 can be selected with a screw with external threads. The plate has a through hole, which can be used to fit the plate onto the screw. Then, the matching nut is tightened to achieve electrical connection.

[0072] To protect the output terminal 11, this embodiment also provides a housing 12. The housing 12 is used to house the output terminal 11, providing an installation position for the output terminal 11 and protecting the output terminal 11. The housing 12 is installed on one side of the battery cell assembly 10, specifically on the end plate 28 of the battery cell assembly 10, so as to facilitate the electrical connection of the output terminal 11 to the battery cell assembly 10.

[0073] The housing 12 includes a cover 13. Because of the cover 13, the housing 12 can be opened to facilitate the connection or maintenance of the output terminal 11. The cover 13 is opened or closed by rotating around a preset axis, which is very convenient to operate. When it is open, it can be suspended at a preset position on the rotation path to keep it open, which facilitates connection and maintenance.

[0074] The preset axis refers to the axis around which the cover 13 rotates when it is opened or closed. The opening or closing can be completed by rotation. This preset axis can be the axis on the housing 12. The preset position of the rotation path refers to a certain position of the cover 13 on the opening and closing path. This position needs to meet the requirements of not hindering the electrical connection and maintenance of the output terminal 11, and not touching the battery cell assembly 10 and other devices, so as to avoid causing resistance to other devices.

[0075] Therefore, the effect of this embodiment is that by setting the cover 13 to be able to hover, the cover 13 will not close under the action of gravity after being opened, nor will it flip in the opposite direction and touch the battery cell assembly 10 and other devices, thus ensuring the normal operation of the output terminal 11 and protecting the battery cell assembly 10 and other devices, and avoiding damage to them.

[0076] In some embodiments, as shown in Figures 6 and 9, the housing 12 further includes a base 14, the output terminal 11 is fixed on the base 14, and the cover 13 is rotatably connected to the base 14 and used to cover the base 14.

[0077] In addition to the cover 13, the housing 12 also includes a base 14. The base 14 is fixedly installed on one side of the battery cell assembly 10, and the output terminal 11 is fixedly installed on the base 14. The cover 13 is rotatably connected to the base 14, and the axis of rotation is the preset axis. By rotating, it can be closed onto the base 14 to cover the output terminal 11.

[0078] The advantage of this embodiment is that it provides a base 14, which provides an installation position for the output terminal 11. The base 14 and the cover 13 together form an accommodating space. The base 14 can also be fixed to one side of the battery cell assembly 10 to achieve the positioning of the base 14 and the output terminal 11 on the base 14.

[0079] In some embodiments, one of the base 14 and the cover 13 includes a sleeve structure 15, and the other includes a shaft structure 16. The sleeve structure 15 and the shaft structure 16 are interlocked, allowing the cover 13 to rotate relative to the base 14. The preset axis is the axis of the shaft structure 16. As shown in Figures 6 and 9, the base 14 is provided with a sleeve structure 15, and the cover 13 is provided with a shaft structure 16.

[0080] Specifically, in order to enable the cover 13 to rotate relative to the base 14, a sleeve structure 15 and a shaft structure 16 are provided. The sleeve structure 15 is a sleeve-shaped structure with an inner hole connecting both ends. The cross-section of the sleeve structure 15 is annular. The shaft structure 16 is a columnar structure, specifically a cylinder. The outer diameter of the shaft structure 16 is equal to the inner diameter of the sleeve structure 15. The shaft structure 16 is inserted into the sleeve structure 15, so that they can rotate relative to each other, thereby enabling the cover 13 to rotate relative to the base 14.

[0081] The base 14 is fixed, while the cover 13 is rotatable. Therefore, when the cover 13 is equipped with the sleeve structure 15, the sleeve structure 15 rotates relative to the shaft structure 16. When the cover 13 is equipped with the shaft structure 16, the shaft structure 16 rotates relative to the sleeve structure 15. The preset axis at this time is the axis of the shaft structure 16, which is also the axis of the sleeve structure 15.

[0082] This embodiment provides a form for rotating the shell cover 13 relative to the base 14. The structure is simple, the operation is convenient, the rotation is stable, and the reliability is good.

[0083] In some embodiments, one of the base 14 and the cover 13 is provided with an elastic protrusion 17, and the other is provided with a groove 18 for accommodating the protrusion 17. When the cover 13 is rotated, the protrusion 17 can be inserted into the groove 18.

[0084] As shown in Figures 6 and 9, a groove 18 is provided on the base 14, and a protrusion 17 is provided on the cover 13.

[0085] This embodiment provides a method for achieving relative hovering between the cover 13 and the base 14.

[0086] Specifically, the cover 13 rotates relative to the base 14. When it rotates to a preset position, the protrusion 17 is inserted into the groove 18. After being inserted, the cover 13 is suspended. This means that there is a certain limiting force between the protrusion 17 and the groove 18 to prevent the cover 13 and the base 14 from rotating relative to each other, thus achieving suspension.

[0087] It should be noted that when it is necessary to leave the hovering position, such as when the cover 13 needs to be closed onto the base 14, the cover 13 can be manually operated. Because the protrusion 17 has a certain degree of elasticity, manual operation can cause the protrusion 17 to deform to a certain extent, forcing the protrusion 17 out of the groove 18, thereby allowing the cover 13 to continue rotating relative to the base 14. However, the weight of the cover 13 alone is not enough to make the protrusion 17 dislodge from the groove 18, thus maintaining the hovering position.

[0088] The structure provided in this embodiment enables the cover 13 to be suspended relative to the base 14. The cover 13 can be suspended as it rotates. The method is simple and the operation is very convenient.

[0089] In some embodiments, as shown in Figures 5-9, the groove 18 is provided on the outer surface of the sleeve structure 15, and the protrusion 17 abuts against the outer surface of the sleeve structure 15 when the cover 13 rotates.

[0090] Specifically, the sleeve structure 15 is a cylindrical structure, so the outer surface shape of the sleeve structure 15 is the outer surface shape of a cylindrical structure. When the cover 13 rotates, the protrusion 17 abuts against the outer surface of the sleeve structure 15.

[0091] The technical means provided in this embodiment can be implemented in the following forms:

[0092] The sleeve structure 15 is located on the base 14, and the shaft structure 16 is located on the shell cover 13. When the sleeve structure 15 is stationary, the shaft structure 16 rotates. The groove 18 is located on the outer surface of the sleeve structure 15, and the protrusion 17 is located on the shell cover 13. When the shaft structure 16 rotates, the protrusion 17 slides along the surface of the sleeve structure 15 and gets stuck in the groove 18 when it encounters it.

[0093] Alternatively, the sleeve structure 15 is located on the shell cover 13, and the shaft structure 16 is located on the base 14. In this case, the shaft structure 16 is stationary, the sleeve structure 15 rotates, the groove 18 is located on the outer surface of the sleeve structure 15, and the protrusion 17 is located on the base 14. At this time, the protrusion 17 is stationary. When the sleeve structure 15 rotates, the surface of the sleeve structure 15 slides against the protrusion 17. When the groove 18 encounters the protrusion 17, the protrusion 17 is inserted into the groove 18.

[0094] In this embodiment, the groove 18 is provided on the outer surface of the sleeve structure 15. This arrangement allows the outer periphery of the sleeve structure 15 to be used as a reference, making it easy to accurately set the hovering position. The groove 18 can be set at a specific position on the circumference of the outer surface of the sleeve structure 15 so that the cover 13 can hover at an accurate preset position. When rotating, the protrusion 17 abuts against the outer surface of the sleeve structure 15 and can be accurately engaged when the groove 18 arrives.

[0095] In some embodiments, as shown in Figures 5-7, 8 and 9, the sleeve structure 15 is disposed on the base 14, and the protrusion 17 is a spring piece protruding from the cover 13.

[0096] Specifically, in this embodiment, the sleeve structure 15 is set on the base 14, the shaft structure 16 is set on the shell cover 13, the groove 18 can be set on the sleeve structure 15, and the protrusion 17 is set on the shell cover 13.

[0097] The protrusion 17 is in the form of a spring sheet and can be a plate-like structure. The protrusion 17 is connected to the cover 13 through one side plate edge and extends outward by a certain length. The extended end abuts against the outer surface of the sleeve structure 15 and can maintain a certain compressive force with the outer surface of the sleeve structure 15. At this time, the spring sheet generates a certain elastic deformation. As the cover 13 rotates, the extended end of the protrusion 17 slides along the outer surface of the sleeve structure 15. When it encounters the groove 18, it is locked into the groove 18, realizing the stop of rotation, thereby realizing the suspension of the cover 13.

[0098] The effect of this embodiment is that the rotation of the shaft structure 16 is more stable and has a better effect than the rotation of the sleeve structure 15. It is also easier to design and process. Therefore, the sleeve structure 15 is set on the base 14, and the protrusion 17 adopts the form of a spring piece, which can make the protrusion 17 maintain a certain squeezing force on the surface of the sleeve structure 15, so that it can be smoothly inserted into the groove 18.

[0099] In some embodiments, as shown in FIG6, FIG7 and FIG9, a raised portion 19 is formed on the outer surface of the sleeve structure 15, and a groove 18 is formed at the raised portion 19, the extension direction of the groove 18 being parallel to a preset axis.

[0100] Specifically, the raised portion 19 refers to the slope or sloping structure formed on the surface of the sleeve structure 15, making the sleeve structure 15 form a cam-like shape, and the groove 18 is opened on the raised portion 19. This is equivalent to the bottom of the groove 18 being higher than the surface of the sleeve structure 15. In this way, when the protrusion 17 abuts against the surface of the sleeve structure 15, it can only make contact without any abutting force. When it encounters the raised portion 19 and enters the groove 18, the protrusion 17 will generate a certain elastic force and produce elastic deformation, which also achieves a better locking state.

[0101] This embodiment avoids the drawback of the protrusion 17 and the surface of the sleeve structure 15 generating a conflicting force, which affects the rotation effect, making the rotation smoother. In addition, the groove 18 is positioned higher, which also makes the locking force of the protrusion 17 greater, effectively restricting the rotation of the cover 13.

[0102] In some embodiments, as shown in Figures 5-7, 8, and 9, the sleeve structure 15 includes two sleeve structures 15, which are symmetrically arranged and spaced apart, and the shaft structure 16 is inserted into the two sleeve structures 15 respectively.

[0103] Specifically, this embodiment provides a number of sleeve structures 15, with two sleeve structures 15 arranged on the same straight line and spaced apart. Shaft structures 16 are inserted into the sleeve structures 15 on both sides respectively. The shaft structure 16 can be a single shaft or two separate shafts. When it is a single shaft, both ends of the shaft are inserted into the sleeve structures 15 respectively. When it is a separate shaft, the two shafts are inserted into the sleeve structures 15 on the corresponding sides respectively.

[0104] The advantage of this embodiment is that the selection of two sleeve structures 15 makes it easier to assemble with the shaft structure 16, and the symmetrical arrangement of the two sleeve structures 15 also makes the cover 13 more stable when rotating, and will not cause any offset or sway in other directions.

[0105] In some embodiments, as shown in Figures 5-7, the shaft structure 16 is an integral structure and both ends of the shaft structure 16 are inserted into the sleeve structure 15 from opposite sides of the two sleeve structures 15.

[0106] This embodiment provides an integral shaft structure 16, meaning the shaft structure 16 is a single, integral shaft with both ends inserted into the sleeve structures 15 on either side. Specifically, it is inserted from opposite sides of the two sleeve structures 15 to complete the connection. This embodiment is a specific form of connecting the shaft structure 16 and the sleeve structure 15, which can achieve a better and more stable rotation effect after connection.

[0107] In some embodiments, as shown in Figures 8 and 9, the shaft structure 16 may include two separate shafts, which are inserted into the sleeve structure 15 from opposite sides of the two sleeve structures 15 respectively.

[0108] Specifically, this embodiment provides another implementation of connecting the shaft structure 16 and the sleeve structure 15. Not only do the two sleeve structures 15 have a certain interval, but the two shafts are also not a whole and are connected separately. This simplifies the length of the shaft structure 16. Using two shorter shafts to be connected separately will not affect the stability and balance of rotation, and makes the structure simpler.

[0109] In some embodiments, as shown in Figures 7 and 9, the sleeve structure 15 is provided with a notch 20 that is opened along the axial direction. The notch 20 is used to avoid the protrusion 17 when the shaft structure 16 is inserted into the sleeve structure 15.

[0110] Specifically, since the protrusion 17 needs to abut against the outer surface of the sleeve structure 15 and, in some cases, needs to maintain a resisting force, when the shaft structure 16 is inserted into the sleeve structure 15, the protrusion 17 may touch the end side of the sleeve structure 15, which may interfere with the insertion of the shaft structure 16. In this case, this embodiment provides a notch 20 axially formed on the sleeve structure 15. The notch 20 is formed on the side of the sleeve structure 15 where the shaft structure 16 is inserted, and extends axially towards the inside of the sleeve structure 15 to form the notch 20, thereby avoiding the protrusion 17 when the shaft structure 16 is inserted. After insertion, if the cover 13 is rotated, the protrusion 17 moves out from the notch 20 and abuts against the outer surface of the sleeve structure 15, maintaining a resisting force with the outer surface of the sleeve structure 15, that is, the protrusion 17 can undergo a certain elastic deformation.

[0111] The notch 20 in this embodiment ensures the smooth insertion of the shaft structure 16 and avoids interference from the protrusion 17.

[0112] In some embodiments, as shown in Figures 5 and 8, a locking block 21 is provided on the base 14, and a latch 22 is provided on the cover 13. When the cover 13 closes the base 14, the locking block 21 engages with the latch 22 to lock the cover 13.

[0113] Specifically, when the cover 13 is placed on the base 14, the cover 13 needs to be kept closed. Therefore, a locking block 21 is provided on the base 14, and a locking slot 22 is provided on the cover 13. When the cover 13 is closed, the locking block 21 can automatically engage with the locking slot 22.

[0114] The locking block 21 can be a protruding structure on the base 14, with an inverted triangular cross-sectional shape. The latch 22 can be a rectangular hole. When the cover 13 is closed, the locking block 21 engages with the latch 22. The shape of the locking block 21 itself can lock into the side of the latch 22 to prevent it from coming out. It should be noted that when there is a large external force, such as when the cover 13 is opened manually, the locking force of the locking block 21 can be overcome, and the cover 13 can be opened. Both the base 14 and the cover 13 can be made of plastic, which can undergo a certain degree of deformation under external force.

[0115] In some embodiments, as shown in Figures 5 and 8, the cover 13 includes a tongue plate 23, which is connected to the main body of the cover 13 via one side edge, and a snap 22 is provided on the tongue plate 23.

[0116] Specifically, the tongue plate 23 is a protruding plate structure, with one side of its plate edge connected to the main body of the shell cover 13, so it has a certain degree of elasticity, which is equivalent to a cantilever setting. In this embodiment, the upper end of the tongue plate 23 is connected to the main body of the shell cover 13 and hangs downward. The latch 22 is set on the tongue plate 23, that is, the latch 22 is a through hole opened on the tongue plate 23.

[0117] The main body of the cover 13 refers to the parts of the cover 13 other than the tongue plate 23.

[0118] In this embodiment, the latch 22 is set on the tongue plate 23. When it is necessary to open the cover 13, the tongue plate 23 can be moved to disengage the latch 21 from the latch 22, and the cover 13 can be opened easily. The design of this embodiment improves the convenience of opening the cover 13.

[0119] In some embodiments, as shown in FIG5, a stepped structure 30 is provided on the base 14, and an overlapping portion 31 adapted to the shape of the stepped structure 30 is provided on the cover 13. When the cover 13 covers the base 14, the overlapping portion 31 overlaps with the stepped structure 30.

[0120] Specifically, the stepped structure 30 has two stepped surfaces of different heights, and the overlapping portion 31 on the cover 13 has a matching stepped surface, allowing the two stepped surfaces to contact each other. Thus, when the cover 13 is closed on the base 14, the stepped surfaces mutually limit and abut against each other, ensuring good stability when the cover 13 is closed.

[0121] In some embodiments, as shown in Figures 5 and 8, the free end of the tongue plate 23 is bent away from the base 14 to form a warped portion 24.

[0122] The tongue plate 23 is a downwardly hanging plate structure. The end connected to the main body of the cover 13 is the upper end, and the end away from the cover 13 is the lower end. The lower end is the free end. When it is necessary to open the cover 13, the tongue plate 23 is moved so that the latch 22 of the tongue plate 23 is disengaged from the latch block 21. The free end provided in this embodiment is a warped part 24 that bends away from the base 14, which makes it convenient to move the tongue plate 23. When moving the tongue plate 23, the warped part 24 can be operated.

[0123] The warped part 24 can be a warped, bent structure, which can include a first part and a second part, wherein the first part and the second part have a certain included angle. The warping means that it is not on the same plane as the surface of the tongue plate 23, making it easy to move the tongue plate 23 by operating this part.

[0124] In some embodiments, as shown in Figures 6 and 9, the base 14 has a planar portion 25, and the output pole 11 is disposed on the planar portion 25.

[0125] The output terminal 11 can be made of a conductive bolt. When the bolt is installed on the base 14, it is preferably installed vertically, which facilitates the connection of conductive components such as the switch. Therefore, this embodiment provides a base 14 with a flat portion 25, and the output terminal 11 is vertically arranged on the flat portion 25. This way, there are no other structures blocking or interfering with it, making it easy for the output terminal 11 to be connected to conductive components. When the switch is connected to the output terminal 11, it can be placed on the flat portion 25. The contact area between the flat portion 25 and the switch is large, which is beneficial to the stability of the switch, that is, to the stability of the relative position between the switch and the output terminal 11.

[0126] In some embodiments, as shown in FIG6, FIG9 and FIG3 and FIG4, the base 14 has a connecting portion 26 for connecting to one side of the battery cell assembly 10, and the connecting portion 26 is located outside the coverage area of ​​the cover 13.

[0127] Specifically, the housing 12 needs to be located on one side of the battery cell assembly 10. The housing 12 is installed on the side of the battery cell assembly 10 via the base 14. In order to achieve better installation, the base 14 is provided with a connecting part 26 for connecting with the structure on the side of the battery cell assembly 10.

[0128] The shape of the connecting part 26 can be set according to the shape of the side structure of the battery cell assembly 10. When the side of the battery cell assembly 10 has a slot-like structure, the shape of the outer contour of the connecting part 26 can be set to match the shape of the slot, and the connection can be achieved by plugging in. When the side structure of the battery cell assembly 10 has a certain solid shape, a hole adapted to the solid shape can be provided on the connecting part 26, and the solid shape can be inserted into the hole to achieve connection.

[0129] The advantage of this embodiment is that the connection through the connecting part 26 is more stable than the ordinary bolt connection. This is because the connecting part 26 has a certain shape and can be matched with the structure of the side of the battery cell assembly 10, which is equivalent to increasing the contact area of ​​the connection part and making it more stable.

[0130] In some embodiments, as shown in Figures 6 and 9, the side of the housing 12 facing the battery cell assembly 10 is open to allow conductive elements to enter the connection output terminal 11.

[0131] Specifically, the conductive element is connected to the output terminal 11 inside the housing 12. However, the conductive element also needs to extend out of the housing 12 to connect to the battery cell assembly 10. Therefore, after the housing cover 13 is closed, there is still space on the housing 12 for the conductive element to pass through. That is, this embodiment provides that the side of the housing 12 facing the battery cell assembly 10 is open, so that the conductive element can pass through. This open part can be located on the housing cover 13. When the housing cover 13 is closed, the open part faces the battery cell assembly 10.

[0132] This embodiment facilitates the connection between the conductive component and the output terminal 11.

[0133] As shown in Figure 2, this application also provides an electrical device, including the battery device 100 provided in any of the above embodiments.
