Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery device and an electrical device. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] In battery devices, individual battery cells are installed within the housing space of the casing. The output terminals connected to the individual battery cells need to be fixed to the output terminal base. In related technologies, grooves are usually set on the beams used to enclose and form the housing space for snapping the output terminal base in place. This reduces the structural strength of the beams and makes the installation space for the output terminal base small, which is inconvenient. Utility Model Content

[0004] The main purpose of this utility model is to propose a battery device and an electrical device, which aims to make the output pole base easy to install and ensure the structural strength of the beam.

[0005] To achieve the above objectives, the battery device proposed in this utility model includes:

[0006] The box body includes a receiving space and beams arranged along the outer periphery of the receiving space;

[0007] A battery cell, wherein the battery cell is housed in the housing space;

[0008] A bracket, which is detachably connected to the side surface of the beam opposite to the receiving space;

[0009] Output electrode base, which is connected to the bracket to be installed on the side of the beam opposite to the receiving space;

[0010] An output electrode plate, one end of which is mounted on the output electrode base and the other end is connected to the battery cell.

[0011] The technical solution of this application, by installing the output electrode base on the side of the beam opposite to the receiving space, eliminates the need for grooves on the beam for installing the output electrode base, ensuring the structural strength of the beam and improving the overall structural reliability of the housing and battery device. Furthermore, installing the output electrode base on the outside of the receiving space and the beam solves the problems of limited installation space and installation difficulties, making the output electrode base easy to install and remove. It also does not occupy space along the height of the beam, which helps reduce the dimensions of the battery device in the height direction. By placing the output electrode base on a bracket and connecting it to the beam, the structure of the bracket can be adapted to the structure of the output electrode base, allowing for stable installation and improving overall structural stability. This requires no major modifications to the beam structure. Moreover, the bracket and beam are detachably connected, facilitating adjustments to the installation positions of the bracket and output electrode base, and also reducing the risk of loose connection of the output electrode due to processing and assembly errors.

[0012] In one embodiment, the bracket includes a first connecting portion and a second connecting portion connected to each other. The first connecting portion is attached to and connected to the surface of the beam opposite to the receiving space. The second connecting portion is bent relative to the first connecting portion in a direction away from the beam. The output pole base is supported on the second connecting portion.

[0013] In this configuration, the bracket fits and connects to the beam through the first connecting part, resulting in a large contact area and easy assembly and disassembly. The output pole base is supported on the second connecting part of the bracket, allowing the output pole base to be stably installed on the bracket and improving the overall structural reliability.

[0014] In one embodiment, a protrusion is provided at the connection position of the first connecting portion and the second connecting portion.

[0015] With this configuration, the overall structure of the bracket is stable, and the first and second connecting parts are less prone to relative deformation.

[0016] In one embodiment, the first connection portion is located on the side of the output electrode base facing the receiving space.

[0017] This configuration makes the overall structure of the bracket and output terminal base compact, reducing the overall volume of the bracket and output terminal base. This helps save space in the enclosure, allowing more space in the enclosure to be used for installing individual battery cells or other electrical connection devices.

[0018] In one embodiment, the second connecting portion includes a first bent segment and a second bent segment that are connected to each other and arranged at an angle, the first bent segment being connected to the first connecting portion, and the second bent segment being connected to the end of the first bent segment away from the first connecting portion.

[0019] In this configuration, the second connection includes a first bent section and a second bent section arranged at an angle, giving the second connection a certain elastic deformation capability. This allows the output electrode base to form an elastic connection with the beam through the bracket, which can play a certain buffering role. It prevents the connection between the output electrode base and the beam from being too tight, which could lead to loosening and damage at the connection point when subjected to impact and vibration, thereby enhancing the vibration and impact resistance of the battery device.

[0020] In one embodiment, the bracket further includes a third connecting portion, which is disposed at the end of the second connecting portion away from the first connecting portion and is bent relative to the second connecting portion. The third connecting portion is connected to the side wall of the output electrode base.

[0021] In this configuration, the bracket is connected to the output terminal base via the third connecting part. After installation, the connection position will not be obstructed, and it can be directly disassembled and installed from the side of the output terminal base in the battery device, which is convenient for maintenance.

[0022] In one embodiment, the third connection portion is located on the side wall of the output electrode base facing the receiving space.

[0023] With this setup, the bracket can be concealed by the output pole base after the entire installation is completed, resulting in a uniform and neat overall appearance.

[0024] In one embodiment, the third connecting portion is provided with a first mounting hole, the side wall of the output electrode base is provided with a second mounting hole, and the battery device further includes a first locking member, which passes through the first mounting hole and the second mounting hole to connect the third connecting portion and the output electrode base.

[0025] With this configuration, the assembly and disassembly of the output base and the third connection part are relatively simple, and the connection strength is high, resulting in high overall structural reliability.

[0026] In one embodiment, the bracket is provided with a third mounting hole, the beam is provided with a fourth mounting hole, and the battery device further includes a second locking member, which passes through the third mounting hole and the fourth mounting hole to connect the bracket and the beam.

[0027] This setup provides a high connection strength between the support frame and the beam, resulting in high overall structural reliability and convenient connection.

[0028] In one embodiment, the beam includes a main body and a supporting part. The main body extends along the edge of the receiving space, and the supporting part and the output pole base are located on the side of the main body opposite to the receiving space. The output pole base is supported by the supporting part.

[0029] This configuration allows the beam to include beam-columns forming the sidewalls of the receiving space and a load-bearing portion connected to the side of the beam-columns facing away from the receiving space. The load-bearing portion can improve the overall structural strength and reliability of the beam. Furthermore, the load-bearing portion can be used to support the output pole base, thereby improving the installation stability and positional stability of the output pole base.

[0030] In one embodiment, the output electrode base is provided with a limiting groove, and one end of the output electrode plate is located in the limiting groove.

[0031] This configuration allows for the use of a limiting slot to limit the installation position of the output electrode plate, preventing it from shifting off the output electrode plate on the output electrode base and improving the overall structural stability.

[0032] In one embodiment, the output electrode plate includes a first extension and a second extension connected to each other. The first extension is located on the side of the beam opposite to the receiving space, and the second extension crosses the beam to extend to the side of the receiving space and is connected to the battery cell.

[0033] This configuration allows the output electrode to be bent so that it can fit against the sides and top of the beam, ensuring stable installation and improving the overall structural stability and reliability.

[0034] This application also proposes an electrical device, including a battery device as described in any of the foregoing embodiments. Attached Figure Description

[0055] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage 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 aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0056] In battery devices, individual battery cells are installed inside a housing. The output terminals connected to the individual battery cells need to be fixed to output terminal bases. In related technologies, grooves are usually set on the beams of the housing for snapping the output terminal bases in place. This reduces the structural strength of the beams and makes the installation space for the output terminal bases small, resulting in inconvenient installation. In addition, after the output terminal bases are fixed in the grooves of the beams, the assembly between the output terminal bases and the corresponding output terminals may not be completed due to manufacturing or installation tolerances, resulting in assembly gaps and thus causing incomplete connections, which affects the performance of the battery device.

[0057] Based on the above considerations, in order to facilitate the installation of the output electrode base 30 and ensure the structural strength of the housing 10, the battery device 100 proposed in this application includes a housing 10, a battery cell 20, a bracket 50, an output electrode base 30, and an output electrode plate 40. The housing 10 is provided with a receiving space 12 and a beam 11 arranged along the outer periphery of the receiving space 12. The battery cell 20 is received in the receiving space 12. The bracket 50 is detachably connected to the side surface of the beam 11 facing away from the receiving space 12. The output electrode base 30 is connected to the bracket 50 to be installed on the side of the beam 11 facing away from the receiving space 12. One end of the output electrode plate 40 is installed on the output electrode base 30, and the other end is connected to the battery cell 20.

[0058] By employing the aforementioned battery device 100, the output electrode base 30 is installed on the side of the beam 11 facing away from the receiving space 12, eliminating the need for grooves on the beam 11 for installing the output electrode base 30. This ensures the structural strength of the beam 11 and improves the overall structural reliability of the housing 10 and the battery device 100. Furthermore, the output electrode base 30 is installed on the outside of the receiving space 12 and the beam 11, solving the problem of limited installation space for the output electrode base 30 and simplifying the assembly process, making the output electrode base 30 easy to assemble and disassemble. It also does not occupy space along the height direction of the beam 11, which helps to reduce the dimensions of the battery device 100 in the height direction. By placing the output electrode base 30 on the bracket 50, and connecting the output electrode base 30 to the beam 11 through the bracket 50, the structure of the bracket 50 can be adapted to the structure of the output electrode base 30, enabling the output electrode base 30 to be stably installed and fixed, improving the overall structural stability. Moreover, no major modifications to the structure of the beam 11 are required. Furthermore, the bracket 50 is detachably connected to the beam 11, which facilitates the adjustment of the installation position of the bracket 50 and the output pole base 30, and also helps to reduce the risk of poor connection of the output pole plate 40 due to processing and assembly errors.

[0059] The battery device 100 disclosed in this application can be used, but is not limited to, in electrical devices such as vehicles 1000, ships, or aircraft. A power system for such an electrical device can be constructed using the battery cells 20 and battery device 100 disclosed in this application. This improves the structural strength and modal frequency of the battery device 100, and enhances its performance stability.

[0060] This application provides an electrical device that uses a battery device 100 as a power source. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Among them, electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0061] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0062] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure 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 is installed inside the vehicle 1000, and the battery can be located at the bottom, front, or rear of the vehicle 1000. The battery 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 starting, navigation, and driving.

[0063] 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.

[0064] Please refer to Figures 2 to 5 as well as Figure 7 , Figure 2 A structural diagram showing a battery cell 20 provided in some embodiments of this application for the battery device 100; Figure 3 This is a partial structural diagram of a battery device 100 provided according to some embodiments of this application. Figure 4 for Figure 3 A partial enlarged view of the mounting position of the output electrode base 30. Figure 5 for Figure 4 Explosion diagram, Figure 7 This is a partial enlarged view of the battery device 100 in another embodiment of this application at the mounting position on the output terminal base 30.

[0065] The battery device 100 includes a housing 10, a battery cell 20, a bracket 50, an output electrode base 30, and an output electrode plate 40. The housing 10 has a receiving space 12 and a beam 11 arranged along the outer periphery of the receiving space 12. The battery cell 20 is received in the receiving space 12. The bracket 50 is detachably connected to the side surface of the beam 11 facing away from the receiving space 12. The output electrode base 30 is connected to the bracket 50 and installed on the side of the beam 11 facing away from the receiving space 12. One end of the output electrode plate 40 is installed on the output electrode base 30, and the other end is connected to the battery cell 20.

[0066] The housing 10 provides a space 12 for housing the battery cells 20. The housing 10 can have various structures, such as a cylinder or a cuboid. The housing 10 is provided with multiple beams 11 to enclose and form the space 12. Taking a cuboid housing 10 as an example, four beams 11 are provided, including two side beams and two end beams. These four beams 11 enclose the space 12 for housing the battery cells 20. Optionally, the housing 10 may also have an installation space for installing electrical connection devices. As shown in the illustrated embodiment, the installation space is located on the side of the end beam opposite to the space 12. The electrical connection devices can be, but are not limited to, a Battery Energy Distribution Unit (BDU) or a Battery Disconnect Unit.

[0067] Optionally, the beam 11 can be, but is not limited to, made of metallic or non-metallic materials. For example, metallic materials can be copper, copper alloys, aluminum, aluminum alloys, nickel, nickel alloys, titanium, titanium alloys, or stainless steel, while non-metallic materials can be ceramics, polyethylene, polypropylene, polyvinyl chloride, polyimide, or polyamide, etc. Optionally, the beam 11 can be a variety of beam structures such as roll-formed beams or profile beams.

[0068] There can be multiple battery cells 20, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 20 are connected in both series and parallel configurations. Multiple battery cells 20 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells 20 is housed within the housing 10. Alternatively, multiple battery cells 20 can first be connected in series, parallel, or in a mixed manner to form a battery module, and then multiple battery modules can be connected in series, parallel, or in a mixed manner to form a whole, which is then housed within the housing space 12. The battery device 100 may also include other structures; for example, the battery device 100 may also include a busbar component for realizing the electrical connection between the multiple battery cells 20.

[0069] Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 20 can be cylindrical, flat, cuboid, or other shapes.

[0070] In the battery device 100, the battery cell 20 is connected to the output electrode base 30 via the output electrode bar 40 and the electrical connection device to realize the charging and discharging operation. The electrical connection device can be, but is not limited to, a battery energy distribution unit (BDU) or a battery disconnect unit.

[0071] The output electrode base 30 is the main load-bearing component that connects the output electrode 40 to the electrical connection device. It is made of insulating material, such as plastic or ceramic. In specific applications, the connection ends of the output electrode 40 and the electrical connection device are fixed to the output electrode base 30 to form an electrical connection. Optionally, the battery device 100 includes a third locking member 80, which passes through the output electrode 40, the connection end of the electrical connection device, and the output electrode base 30, thereby fixing the output electrode 40 and the connection end of the electrical connection device to the output electrode base 30; wherein the third locking member 80 can be a bolt or other connection structure.

[0072] In this embodiment, a bracket 50 is provided on the surface of the beam 11 facing away from the receiving space 12, and the output electrode base 30 is connected to the bracket 50 to be installed on the side of the beam 11 facing away from the receiving space 12. This arrangement eliminates the need for a groove on the beam 11 for installing the output electrode base 30, ensuring the structural strength of the beam 11 and improving the overall structural reliability of the housing 10 and the battery device 100. Furthermore, the output electrode base 30 is installed on the outside of the receiving space 12 and the beam 11, solving the problem of limited installation space for the output electrode base 30 and simplifying the assembly process, making the output electrode base 30 easy to assemble and disassemble. It also does not occupy space along the height direction of the beam 11, which helps to reduce the dimensions of the battery device 100 in the height direction. Furthermore, the output electrode base 30 serves as the main load-bearing component connecting the output electrode bar 40 to the electrical connection device. Its external design facilitates adjustments to the installation position of the output electrode base 30, eliminating the limitations imposed by recesses. This reduces tolerances arising from workpiece machining and overall assembly, preventing connection problems such as loose connections between the output electrode bar 40 and the output electrode base 30, thereby improving product consistency and performance reliability. The external design also makes the output electrode base 30 more accessible, simplifying maintenance and repair. It also better supports modular design; for example, with the output electrode base 30 located outside the receiving space 12, additional battery modules can be quickly connected, making it easier to expand or upgrade the battery device 100, thereby increasing its capacity and power.

[0073] The bracket 50 can be a sheet metal part, a plastic part, or made of other materials. The bracket 50 can be configured as, but is not limited to, a block structure or a bent sheet metal structure. By mounting the output electrode base 30 on the bracket 50, and connecting the output electrode base 30 to the beam 11 via the bracket 50, the structure of the bracket 50 can be adapted to the structure of the output electrode base 30, allowing for stable installation and improving overall structural stability; and without requiring significant modifications to the structure of the beam 11. Furthermore, the bracket 50 and the beam 11 are detachably connected, facilitating adjustments to the installation positions of the bracket 50 and the output electrode base 30, and also reducing the risk of loose connections in the output electrode bar 40 due to processing and assembly errors.

[0074] Optionally, the connection between the bracket 50 and the beam 11 can be, but is not limited to, bonding, welding, or, in the following embodiment, connection via the second locking member 70. Optionally, the connection between the bracket 50 and the output electrode base 30 can be, but is not limited to, bonding, snap-fitting, welding, or connection using bolts, rivets, or other locking members.

[0075] In this embodiment, the output electrode base 30 is located outside the receiving space 12, without occupying space within the receiving space 12, thus providing greater flexibility for the arrangement of other components. For example, more space can be used to install more battery cells 20, or a more efficient cooling system, thereby achieving space optimization design and improving the energy density and overall performance of the battery device 100. It can also increase the physical distance between the output electrode base 30 and the battery cells 20 or other electrical components, thereby enhancing electrical isolation; effectively reducing the risk of short circuits and improving the electrical safety of the battery device 100. The outward-moving design of the output electrode base 30 also makes it easier to install insulating materials or protective covers, further improving safety performance.

[0076] Secondly, the battery device 100 generates a large amount of heat during charging and discharging. If this heat cannot be dissipated in time, the temperature of the battery device 100 will rise, affecting its performance and lifespan, and even causing safety issues such as thermal runaway. The output terminal base 30, as the main load-bearing component connecting the output terminal bar 40 to the electrical connection device, is prone to becoming a heat concentration area. By moving the output terminal base 30 outward, the heat dissipation space can be increased, the heat transfer path improved, and heat dissipation efficiency enhanced; it also facilitates the integration of heat sinks or cooling systems, further optimizing the thermal management performance of the battery device 100.

[0077] Furthermore, the battery device 100 is subject to mechanical stresses such as vibration and impact during vehicle 1000 operation or equipment operation. The battery device 100 also undergoes thermal expansion due to temperature changes during operation. These mechanical stresses, including vibration and impact, and the stresses during thermal expansion, may cause loosening or damage to the connection structure between the output electrode base 30 and the beam 11, thereby affecting the reliability of the battery device 100. Optionally, the output electrode base 30 can be elastically connected to the beam 11, or a buffer structure can be provided at the connection point to enhance the vibration and impact resistance of the battery device 100. The elastic connection can be achieved by fixing an elastic mounting bracket to the beam 11 for mounting the output electrode base 30, such as using a rubber support, an elastic arm, or setting the bracket 50 in the following embodiment as an elastically bendable structure; no limitation is made here. Additionally, a thermal expansion compensation structure can be provided to reduce the impact of thermal expansion on the connectors and improve the reliability and durability of the battery device 100 in high-temperature environments. Moving the output electrode base 30 outwards facilitates the design of the elastic connection structure, buffer structure, and thermal expansion compensation structure.

[0078] Optionally, temperature sensors, current sensors, and other detection devices can be installed on the output terminal base 30 to enable real-time monitoring and fault diagnosis of the battery device 100's operating status, thereby improving the maintainability and performance stability of the battery device 100. Moving the output terminal base 30 outward allows for easier integration of sensors and detection devices.

[0079] Optionally, the output electrode base 30 is installed on the side of the beam 11 facing away from the receiving space 12, so that the output electrode base 30 can be directly connected to the beam 11, or in the following embodiment, the output electrode base 30 is installed on the beam 11 by means of the bracket 50.

[0080] Optionally, the output electrode base 30 or the bracket 50 can be fixed on the surface of the beam 11 facing away from the receiving space 12, or in the following embodiment, the beam 11 is configured to include a main body 111 and a supporting part 112, the main body 111 forming the side wall of the receiving space 12, and the output electrode base 30 or the bracket 50 fixed on the supporting part 112.

[0081] Please refer to Figure 5 and Figure 6 According to one embodiment of this application, the bracket 50 includes a first connecting portion 51 and a second connecting portion 52 connected to each other. The first connecting portion 51 is attached to and connected to the surface of the beam 11 facing away from the receiving space 12. The second connecting portion 52 is bent relative to the first connecting portion 51. The output pole base 30 is supported on the second connecting portion 52.

[0082] In this embodiment, the bracket 50 includes a first connecting part 51 and a second connecting part 52 arranged at an angle. The first connecting part 51 is a plate-shaped structure that is attached to and connected to the surface of the beam 11 facing away from the receiving space 12, so that the contact area between the bracket 50 and the beam 11 is large and the bracket is easy to assemble and disassemble.

[0083] The second connecting portion 52 can be configured as a plate-like structure, or it can include at least two connected bent segments. For example, in the illustrated embodiment, the second connecting portion 52 includes a first bent segment 521 and a second bent segment 522 connected at an angle. The first bent segment 521 is connected to the first connecting portion 51, and the second bent segment 522 is connected to the end of the first bent segment 521 away from the first connecting portion 51. Alternatively, the second connecting portion 52 can also be configured as a block-like structure. The output electrode base 30 is supported on the second connecting portion 52 of the bracket 50, allowing the output electrode base 30 to be stably installed on the bracket 50, thus improving the overall structural reliability.

[0084] Optionally, the bracket 50 can be made of sheet metal and manufactured by processes such as bending or stamping, which is relatively convenient.

[0085] Please refer to Figure 5 and Figure 6 According to one embodiment of this application, a protrusion 54 is provided at the connection position of the first connecting part 51 and the second connecting part 52. With this arrangement, the overall structure of the bracket 50 is stable, and the first connecting part 51 and the second connecting part 52 are not prone to relative deformation.

[0086] Combined with reference Figure 4 and Figure 5 According to one embodiment of this application, the first connection portion 51 is provided on the side of the output electrode base 30 facing the receiving space 12.

[0087] This arrangement makes the overall structure of the bracket 50 and the output terminal base 30 compact, reducing the overall volume of the bracket 50 and the output terminal base 30. This helps save space in the housing 10, allowing more space in the housing 10 to be used for installing battery cells 20 or other electrical connection devices.

[0088] Please refer to Figure 5 and Figure 6 In one embodiment, the second connecting portion 52 includes a first bent section 521 and a second bent section 522 that are connected to each other and arranged at an angle. The first bent section 521 is connected to the first connecting portion 51, and the second bent section 522 is connected to the end of the first bent section 521 that is away from the first connecting portion 51.

[0089] In this configuration, the second connecting part 52 includes a first bent section 521 and a second bent section 522 arranged at an angle, giving the second connecting part 52 a certain elastic deformation capability. This allows the output electrode base 30 to form an elastic connection with the beam 11 through the bracket 50, which can play a certain buffering role and prevent the connection between the output electrode base 30 and the beam 11 from being too tight, which could lead to loosening and damage at the connection position when subjected to impact and vibration. This enhances the vibration and impact resistance of the battery device 100.

[0090] Combined with reference Figures 4 to 7 According to one embodiment of this application, the bracket 50 further includes a third connecting portion 53, which is disposed at the end of the second connecting portion 52 away from the first connecting portion 51 and is bent relative to the second connecting portion 52. The third connecting portion 53 is connected to the side wall of the output electrode base 30.

[0091] In this embodiment, the bracket 50 further includes a third connecting part 53 for connecting with the output electrode base 30. The third connecting part 53 is connected to the end of the second connecting part 52 away from the first connecting part 51. Optionally, the third connecting part 53 can be configured as a connecting lug or a flange. With this configuration, the contact area between the output electrode base 30 and the bracket 50 is large, which can better limit the position of the output electrode base 30 and make the output electrode base 30 stably installed. In addition, the connection position between the bracket 50 and the output electrode base 30 will not be obstructed after installation, and can be directly disassembled from the side of the output electrode base 30 in the battery device 100, which is convenient for maintenance.

[0092] Combined with reference Figure 4 and Figure 5 According to one embodiment of this application, the third connecting portion 53 is located on the side wall of the output electrode base 30 facing the receiving space 12. Using this method, after the overall installation is completed, the bracket 50 can be concealed by the output electrode base 30, resulting in a uniform and neat overall appearance. Furthermore, when bolts or rivets are used to connect the output electrode base 30 and the third connecting portion 53, the side wall of the output electrode base 30 can be clamped between the third connecting portion 53 and the bolt or rivet head, thereby better limiting and fixing the output electrode base 30 and improving structural stability.

[0093] Please refer to Figure 4 and Figure 5 According to one embodiment of this application, the third connecting part 53 is provided with a first mounting hole 531, the side wall of the output electrode base 30 is provided with a second mounting hole 31, and the battery device 100 further includes a first locking member 60, which passes through the first mounting hole 531 and the second mounting hole 31 to connect the third connecting part 53 and the output electrode base 30.

[0094] In this embodiment, a first mounting hole 531 is provided on the third connecting part 53, and a second mounting hole 31 is provided on the output electrode base 30. Both the first mounting hole 531 and the second mounting hole 31 can be open holes, or one of them can be a screw hole. Correspondingly, the first locking member 60 can be a blind rivet, a plastic rivet, a bolt, or other structure. This connection method simplifies the assembly and disassembly of the output electrode base 30 and the third connecting part 53, resulting in high connection strength and overall structural reliability.

[0095] Please refer to Figure 7 According to one embodiment of this application, the beam 11 includes a main body 111 and a supporting part 112. The supporting part 112 and the output pole base 30 are disposed on the side of the main body 111 facing away from the accommodating space 12, and the output pole base 30 is supported on the supporting part 112.

[0096] In this embodiment, the main body 111 of the beam 11 extends along the edge of the receiving space 12 to enclose the receiving space 12 with other beams 11; the supporting part 112 is disposed on the beam column facing away from the receiving space 12. The supporting part 112 can extend along the length direction of the main body 111, or it can be disposed only at the position where the output pole base 30 is installed; or multiple supporting parts 112 are disposed at intervals along the length direction of the main body 111. The provision of the supporting part 112 can improve the overall structural strength and reliability of the beam 11; and the supporting part 112 can be used to support the output pole base 30, thereby improving the installation stability and positional stability of the output pole base 30.

[0097] Please refer to Figure 4 and Figure 5 According to one embodiment of this application, the bracket 50 is provided with a third mounting hole 511, the beam 11 is provided with a fourth mounting hole 113, and the battery device 100 further includes a second locking member 70, which passes through the third mounting hole 511 and the fourth mounting hole 113 to connect the bracket 50 and the beam 11.

[0098] In this embodiment, a third mounting hole 511 is provided on the bracket 50, and a fourth mounting hole 113 is provided on the beam 11. Both the third mounting hole 511 and the fourth mounting hole 113 can be plain holes, or the fourth mounting hole 113 can be a screw hole. Correspondingly, the second locking member 70 can be a blind rivet, a plastic rivet, a bolt, or other similar structure. This connection method provides high connection strength between the bracket 50 and the beam 11, high overall structural reliability, and convenient connection.

[0099] Please refer to Figure 4 According to one embodiment of this application, the output electrode base 30 is provided with a limiting groove 32, and one end of the output electrode plate 40 is located in the limiting groove 32.

[0100] This configuration allows the limiting groove 32 to limit the installation position of the output electrode plate 40, and also prevents the output electrode plate 40 from being misaligned on the output electrode base 30, thereby improving the overall structural stability.

[0101] Please refer to Figure 4 According to one embodiment of this application, the output electrode plate 40 includes a first extension 41 and a second extension 42 connected to each other. The first extension 41 is located on the side of the beam 11 opposite to the receiving space 12, and the second extension 42 crosses the beam 11 to extend to the side of the receiving space 12 and is connected to the battery cell 20.

[0102] In this embodiment, the output electrode plate 40 has a bent structure, including a first extension section 41 disposed opposite to the side wall of the beam 11 and a second extension section 42 spanning the top surface of the beam 11, so that the output electrode plate 40 can be close to the side and top surface of the beam 11 for stable installation, thereby improving the overall structural stability and reliability.
