Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery box, battery device, energy storage device, and electrical equipment. Background Technology

[0002] In related technologies, the fixing and management of wiring harnesses is a critical aspect of traditional battery box design. Typically, wiring harnesses are fixed by welding or installing harness brackets onto the box. However, installing harness brackets requires reserved installation space, which occupies box space; it also complicates the assembly process, consuming more materials and time, increasing production costs; furthermore, the wiring harness fixing strength is low, affecting system stability and reliability. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a battery box, battery device, energy storage device, and electrical equipment that can reduce production costs and improve the space utilization of the battery box.

[0004] A first aspect of this application provides a battery box, the battery box comprising:

[0005] The housing is used to hold the battery modules;

[0006] A bracket is installed on the housing; the bracket includes a bracket body and a mounting component, the bracket body is used to install the battery acquisition unit; the mounting component is used to fix the wiring harness, the wiring harness is used to connect the battery module and the battery acquisition unit;

[0007] At least a portion of the bracket body and the mounting component are integrally formed.

[0008] In some embodiments, the bracket body has a cable passage, and the mounting member faces the cable passage.

[0009] By incorporating cable routing ports, space can be provided to avoid wiring harnesses, and the weight of the main bracket body can be reduced, thus lightening the overall weight of the battery box. The mounting components are located within the cable routing ports, further reducing the space occupied by wiring harnesses and improving the space utilization of the battery box.

[0010] In some embodiments, the mounting component includes:

[0011] The main body is connected at one end to the support body and suspended at the other end.

[0012] The suspended end of the main body is far away from the main support, which makes it easier to arrange the wire harness at the suspended end of the main body to avoid interference between the wire harness and the main support body.

[0013] In some embodiments, the main body has mounting holes for directly or indirectly fixing the wire harness.

[0014] The mounting holes can be used with other structures, such as fasteners, to secure the wire harness; or the mounting holes can directly secure the wire harness without the need for other fasteners.

[0015] In some embodiments, the main body includes:

[0016] The mounting hole is located in the straight section;

[0017] The bent section connects the bracket body and the straight section respectively, so that the straight section extends toward the cable passage.

[0018] The angle between the straight section and the main body of the bracket can be set by the bending section, so that the straight section extends into the cable passage for the arrangement of the cable harness.

[0019] In some embodiments, the bent section includes an extension area and a first rounded corner area, the extension area being connected to the bracket body, the first rounded corner area being connected to the extension area, and the inner radius of the first rounded corner area being greater than or equal to the plate thickness of the mounting member; the straight section forms a 90-degree angle with the bracket body; the straight section includes a neck area and a mounting area, the neck area being connected to the first rounded corner area, the mounting area being connected to the neck area, and the width of the mounting area being greater than the width of the neck area.

[0020] In this way, the straight section can face the connector of the battery acquisition unit, making it easy to fix according to the direction of the wiring harness. The inner radius of the first rounded corner area is greater than or equal to the thickness of the mounting plate, which can reduce the possibility of cracking during the stamping of the parts, facilitate the forming of parts, reduce the scrap rate of parts, and reduce the production cost of parts.

[0021] In some embodiments, the distance between the extension area and the bracket body at both ends of the cable passage is greater than or equal to 10 mm.

[0022] This reduces the likelihood of cracking during sheet metal processing, facilitates part forming, reduces part scrap rate, and lowers part production costs.

[0023] In some embodiments, the distance between the mounting area and the first rounded corner area is greater than or equal to 2 mm.

[0024] This reduces the likelihood of cracking during sheet metal processing, facilitates part forming, reduces part scrap rate, and lowers part production costs.

[0025] In some embodiments, the distance between the extension area and the bracket body at both ends of the cable passage is greater than or equal to 10 mm; the distance between the mounting area and the first rounded corner area is greater than or equal to 2 mm.

[0026] This reduces the likelihood of cracking during sheet metal processing, facilitates part forming, reduces part scrap rate, and lowers part production costs.

[0027] In some embodiments, the battery box further includes a fastener, the fastener comprising:

[0028] A mounting base is installed in the mounting hole;

[0029] Cable ties, installed on the mounting base, are used to secure the wire harness.

[0030] Cable ties can limit the movement of wire harnesses, and by setting the positions of mounting brackets and fixing seats, the wire harnesses can be arranged to achieve reasonable wiring.

[0031] In some embodiments, the mounting component further includes:

[0032] The reinforcing portion is connected to both sides of the main body portion, and the reinforcing portion is at least partially bent relative to the main body portion.

[0033] Thus, by adding reinforcing parts, the structural strength of the mounting component can be improved. Since the reinforcing parts are at least partially bent relative to the main body, the possibility of interference between the wiring harness and the reinforcing parts on both sides of the main body can be reduced during wiring harness installation, thus simplifying the wiring harness installation process.

[0034] In some embodiments, the mounting element is connected to the side of the bracket body away from the connector of the battery acquisition unit.

[0035] The battery acquisition unit's connector is located on one side of the bracket body and at the cable pass-through port. This ensures a certain distance between the connector and the mounting hardware, facilitating the securing of the wiring harness, such as multiple harnesses, to prevent excessive bending angles that could damage the harnesses.

[0036] In some embodiments, the support body includes:

[0037] A backplate is installed on the housing, and the backplate is used to install the battery acquisition unit.

[0038] Liner plate, installed on the back plate;

[0039] The mounting component and the liner are integrally formed, or the mounting component and the back plate are integrally formed.

[0040] The backplate provides mounting space for the battery acquisition unit and protects it. The liner further enhances the structural strength of the support structure.

[0041] In some embodiments, the battery box further includes:

[0042] A cover plate is installed on the support body and forms a receiving cavity with the support body to accommodate the battery acquisition unit.

[0043] The cover plate protects the battery acquisition unit, reducing the possibility of structural damage. Removing the cover plate allows for maintenance of the battery acquisition unit.

[0044] In some embodiments, the mounting element is constructed as a folded structure formed by punching and bending the base material of the bracket body.

[0045] In this way, the waste generated during the stamping of the bracket body can be utilized, while the material that would otherwise be stamped away can be retained to produce the mounting parts. This reduces the amount of material used in production, improves material utilization, and lowers production costs.

[0046] In some embodiments, the mounting element is configured such that the interface between it and the support body is a fused-interwoven overhang structure.

[0047] This simplifies the production process and improves the structural load-bearing capacity of the mounting components and the main support structure.

[0048] A second aspect of this application provides a battery device, comprising:

[0049] The battery box described in any one of the embodiments of this application;

[0050] The battery module is housed within the casing.

[0051] The battery acquisition unit is mounted on the main body of the bracket;

[0052] The wiring harness is an interface that electrically connects the battery module and the battery acquisition unit.

[0053] In some embodiments, the battery device further includes a control panel, with the control panel located on both sides of the bracket; the control panels on both sides are electrically connected to the interface of the battery acquisition unit via the wiring harness.

[0054] In some embodiments, the bracket body has a cable passage, and the mounting member faces the cable passage; the distance between the portion of the mounting member located at the connection point of the bracket body and the two ends of the bracket body located at the cable passage is greater than or equal to 10 mm, and the horizontal distance between the centerline of the mounting member and the centerline of the adjacent plug interface is 10~50 mm.

[0055] If the distance between adjacent connectors and mounting hardware is too small, the wiring harness will experience significant bends during routing, making installation difficult and potentially causing substantial damage to the harness structure, or even preventing connection. Conversely, if the distance is too large, the harness will occupy excessive space, hindering space utilization. Therefore, controlling the horizontal distance between the mounting hardware and adjacent connectors can reduce the bends in the wiring harness and minimize wear and tear.

[0056] This application also provides a battery device, including:

[0057] The battery box described in any one of the embodiments of this application;

[0058] The battery module is housed within the casing.

[0059] The battery acquisition unit is mounted on the main body of the bracket;

[0060] The wiring harness is an interface that electrically connects the battery module and the battery acquisition unit.

[0061] The distance between the installation area and the battery acquisition unit is greater than or equal to 3.5 mm.

[0062] This reduces the likelihood of battery acquisition unit malfunction due to wear between the mounting components and the battery acquisition unit, thereby reducing the possibility of battery box malfunction due to battery acquisition unit malfunction.

[0063] In some embodiments, the mounting component further includes a reinforcing portion, which is connected to both sides of the mounting area. The reinforcing portion is at least partially bent relative to the mounting area, and the distance between the reinforcing portion and the battery acquisition unit is greater than or equal to 3.5 mm.

[0064] This reduces the likelihood of battery acquisition unit malfunction due to wear between the mounting components and the battery acquisition unit, thereby reducing the possibility of battery box malfunction due to battery acquisition unit malfunction.

[0065] In some embodiments, the reinforcing part includes a second rounded corner area and a flanged area, the flanged area being connected to the mounting area through the second rounded corner area, the inner radius of the second rounded corner area being greater than or equal to the plate thickness of the mounting part, and the flanged length of the flanged area being less than or equal to 3.7 mm.

[0066] The inner radius of the second rounded corner area is greater than or equal to the thickness of the mounting plate. This reduces the possibility of cracking during component stamping, facilitates component forming, reduces scrap rate, and lowers production costs. When the distance between the straight section and the inner side of the battery acquisition unit is 8.7mm and the inner radius of the second rounded corner area is greater than or equal to 1.5mm, the flange length of the flanged area is set to less than or equal to 3.7mm to meet the spacing requirements. This ensures that the distance between the mounting area and the battery acquisition unit is greater than or equal to 3.5mm.

[0067] A third aspect of this application provides an energy storage device, comprising:

[0068] The battery device described in this application embodiment is used to store or provide electrical energy.

[0069] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage devices can store electrical energy as needed and output it when appropriate.

[0070] A fourth aspect of this application provides an electrical appliance, including:

[0071] The battery device described in this application embodiment is used to store or provide electrical energy.

[0072] Electrical equipment includes, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc.

[0073] The battery box, battery device, energy storage device, and electrical equipment provided in this application embodiment integrate at least a portion of the support body and the mounting components into a single molded part. This eliminates the need for additional installation or welding of the mounting components, reducing processes, assembly complexity, and production efficiency. Furthermore, the elimination of the need to reserve operating space for the mounting components allows for a more compact and rational spatial layout, improving the space utilization of the box and reducing production costs.

[0096] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively 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 the application areas of power batteries, the market demand is also constantly increasing.

[0097] In related technologies, the fixing and management of wiring harnesses is a critical aspect of traditional energy storage box system design. Typically, wiring harnesses are fixed by welding specialized wiring harness brackets onto the box body. However, installing these brackets requires reserved installation space, occupies internal box space, and incurs additional material and manufacturing costs, increasing production costs. It can also make the assembly process more complex and time-consuming. Furthermore, insufficient fixing strength can lead to wiring harnesses loosening or wearing during operation, thus affecting the stability and reliability of the entire energy storage system.

[0098] In view of this, embodiments of this application provide a battery box that can reduce production costs and improve the space utilization rate of the battery box.

[0099] This application also provides a battery device, including a battery module, a wiring harness, a battery acquisition unit, and a battery box according to any one of the embodiments of this application. The battery module is disposed within a receiving cavity; the wiring harness electrically connects the battery module and the battery acquisition unit to an interface.

[0100] This application also provides an energy storage device, including a battery device according to this application, which is used to store or provide electrical energy.

[0101] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage devices can store electrical energy as needed and output it when appropriate. For example, energy storage devices can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. Energy storage devices include energy storage containers and energy storage cabinets.

[0102] This application also provides an electrical device, including a battery device according to any one of the embodiments of this application, for storing or providing electrical energy.

[0103] Electrical devices include, but are 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. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0104] For example, the electrical equipment can be a vehicle. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle; a new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. As shown in the figure, a battery device is installed inside the vehicle, and the battery device can be located at the bottom, front, or rear of the vehicle. The battery device can be used to power the vehicle; for example, the battery device can serve as the vehicle's operating power source. The vehicle may also include a controller and a motor. The controller is used to control the battery device to power the motor, for example, to meet the power needs of the vehicle during starting, navigation, and driving.

[0105] In some embodiments of this application, the battery device can not only serve as the operating power source for the vehicle, but also as the driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0106] A battery module is a single physical module that includes one or more battery cells to provide higher voltage and capacity.

[0107] In the embodiments of this application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0108] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0109] Although not illustrated, a single battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charging and discharging process of a single battery cell, active ions, such as lithium ions, repeatedly insert and extract between the positive and negative electrodes. The separator, positioned between the positive and negative electrodes, prevents short circuits while allowing active ions to pass through.

[0110] In some embodiments, the electrode assembly has tabs that allow current to be drawn from the electrode assembly. The tabs include a positive tab and a negative tab.

[0111] In some embodiments, the electrode assembly can be a wound structure, a stacked structure, or a hybrid structure of wound and stacked.

[0112] In some embodiments, a single battery cell may include a housing. The housing is used to encapsulate components such as electrode assemblies and electrolytes. The housing may be made of steel, aluminum, plastic (e.g., polypropylene), composite metal (e.g., copper-aluminum composite), or aluminum-plastic film.

[0113] In some embodiments, the housing can be a sealed structure or a non-sealed structure. As an example, when the housing is a non-sealed structure, it serves to protect the electrode assembly, and a sealing bag is included between the housing and the electrode assembly to encapsulate the electrode assembly and electrolyte. Specifically, the sealing bag can be a bag-shaped insulating component or an aluminum-plastic film. When the housing is a sealed structure, it is used to encapsulate components such as the electrode assembly and electrolyte.

[0114] In some embodiments, at least one electrode terminal is provided on the housing, and the electrode terminal is electrically connected to the tab. The electrode terminal can be directly connected to the tab, or it can be indirectly connected to the tab through a current collector. The electrode terminal can be provided on the end cap or on the housing.

[0115] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0116] Below, refer to Figures 1 to 15 Some embodiments of this application will be described in detail.

[0117] Please see Figures 1-7 The battery box 100 includes a box body 10 and a bracket 20. The box body 10 is used to place the battery module; the bracket 20 is installed on the box body 10; the bracket 20 includes a bracket body 21 and a mounting component 22. The bracket body 21 is used to install the battery acquisition unit 210; the mounting component 22 is used to fix the wiring harness 220, and the wiring harness 220 is used to connect the battery module and the battery acquisition unit 210; wherein, at least a portion of the bracket body 21 and the mounting component 22 are integrally formed.

[0118] Understandable Figure 1 , Figure 4 , Figure 6 as well as Figure 14 The battery module and part of the housing 10 are omitted, with only the bottom plate remaining in the housing 10. For example, the battery module includes multiple battery cells, which are arranged sequentially within the housing 10.

[0119] The housing 10 has a receiving space, within which the battery module is located. The structure of the housing 10 is not limited. Exemplarily, the structure of the housing 10 may include a lower housing and a cover, with the cover fitting over the lower housing to form the receiving space. The structure of the housing 10 may also consist of a top cover, side panels, and a bottom plate.

[0120] The battery acquisition unit 210 (CSC, Cell Supervision Circuit) is mainly used to perform functions such as voltage sampling, temperature sampling, voltage equalization, and sampling anomaly detection of individual battery cells in the battery device 200, and to upload the collected and monitored information to the main control unit.

[0121] The structural form of the support body 21 is not limited; for example, it can be I-shaped or L-shaped, and at least part of the body can be ring-shaped or sheet-shaped. The support body 21 can be a one-piece molded part or a modular assembly.

[0122] At least a portion of the bracket body 21 and the mounting component 22 are integrally formed, meaning that the bracket body 21 can be integrally formed and integrally formed with the mounting component 22. Alternatively, the bracket body 21 may include at least two separately formed components, at least one of which is integrally formed with the mounting component 22.

[0123] For example, please refer to Figure 2 , Figure 4 and Figure 5 The support body 21 is an assembly, including a back plate 211 and a liner 212. The back plate 211 is mounted on the housing 10 and is used to mount the battery acquisition unit 210. The liner 212 is mounted on the back plate 211. The back plate 211 and the mounting component 22 are integrally formed. Alternatively, the liner 212 and the mounting component 22 are integrally formed. The back plate 211 provides mounting space for the battery acquisition unit 210 and protects it. The liner 212 further enhances the structural strength of the support body 21. For example, Figure 6 , Figure 8 , Figure 10 The structure of the liner 212 and the mounting member 22 integrally formed in the bracket body 21 is shown. To easily illustrate the mounting orientation of the liner relative to the back plate 211, Figure 6 , Figure 8 , Figure 10 The diagrams for mounting fasteners, such as bolts, are all retained.

[0124] In other embodiments, the bracket body 21 includes a back plate 211 and does not have a liner 212. The back plate 211 is mounted on the housing 10 and is used to mount the battery acquisition unit 210. The back plate 211 and the mounting component are integrally formed.

[0125] In some embodiments, please refer to Figure 4 and Figure 5 The battery box 100 also includes a cover plate 40, which is mounted on the back plate 211 and forms a receiving cavity with the back plate 211 to accommodate the battery acquisition unit 210. For example, the cover plate 40 and the liner plate 212 are located on opposite sides of the back plate 211. The cover plate 40 protects the battery acquisition unit 210 and reduces the possibility of structural damage to the battery acquisition unit 210. The battery acquisition unit 210 can be repaired by removing the cover plate 40.

[0126] Mounting component 22 can organize the arrangement of wire harness 220, preventing it from becoming cluttered, occupying too much space, and hindering later maintenance. For example, the bracket body 21 and mounting component 22 are made of metal materials, such as steel, aluminum, or alloys, which can meet the structural strength requirements of the bracket body 21 and mounting component 22.

[0127] For example, the support body 21 and the mounting component 22 can also be made of plastic. For example, they can be polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polyimide (PI), carbon fiber reinforced plastics (such as PA, PPA), or ultra-high molecular weight polyethylene (UHMWPE).

[0128] The battery box 100 provided in this application embodiment has at least a portion of the bracket body 21 and the mounting component 22 constructed as a single molded part, eliminating the production steps of additional installation or welding of the mounting component 22, reducing processes, assembly complexity, and improving production efficiency. Meanwhile, additional installation or welding of the mounting component 22 occupies internal space in the box 10, hindering space utilization, and requires a separate process and additional material preparation, leading to a more complex production process and increased production time. Furthermore, additional installation or welding of the mounting component 22 makes it difficult to ensure sufficient structural strength of the bracket 20, potentially causing loosening during operation and affecting the stability and reliability of the entire battery box 100. In this application, since at least a portion of the mounting component 22 and the bracket body 21 are constructed as a single molded part, there is no need to reserve operating space for the installation of the mounting component 22, resulting in a more compact and rational spatial layout. This improves the space utilization of the box 10, reduces assembly complexity, decreases subsequent maintenance time, and lowers production costs. Simultaneously, the compact spatial layout also reduces the overall weight of the battery box 100.

[0129] In some embodiments, the mounting member 22 is constructed as a folded structure formed by punching and bending the base material of the bracket body 21, that is, the mounting member 22 is stamped and formed on the bracket body 21. The folded structure can be formed by folding the base material of the bracket body 21 once or multiple times to form mounting members with different shapes.

[0130] In this way, the waste generated during the stamping of the main body 21 can be utilized, while the material that would otherwise be stamped off can be retained and the mounting part 22 can be generated by folding it using a stamping die. This reduces the amount of material used in production, improves material utilization, and lowers production costs.

[0131] In other embodiments, the mounting component 22 is constructed with a fused-overlay overhang structure at its mating surface with the support body 21, meaning the mounting component 22 and the support body 21 are integrally molded using an injection molding process. The overhang structure can be located at the outer edge of the support body 21 or the edge of an internal opening, with its shape and thickness designed according to strength requirements. This simplifies the production process and improves the structural load-bearing capacity of the mounting component 22 and the support body 21.

[0132] It is understood that the angle of the mounting component 22 relative to the bracket body 21 is not limited and can be adaptively set according to the needs of fixing the wiring harness 220. For example, please refer to... Figure 11 The mounting member 22 may be located on the side of the bracket body 21 away from the battery module. In other embodiments not shown, the mounting member 22 may be located on the side of the bracket body 21 facing the battery module; or, a portion of the mounting member 22 may be located on the side of the bracket body 21 facing the battery module, and another portion may be located on the side of the bracket body 21 away from the battery module.

[0133] For example, please refer to Figures 6-11 The mounting component 22 has mounting holes 221a. These are used to directly or indirectly secure the wire harness 220. The mounting holes 221a can mate with other structures, such as fasteners 30, to secure the wire harness 220; or the mounting holes 221a can directly secure the wire harness 220 without requiring the use of other fasteners 30.

[0134] In some embodiments, please refer to Figure 3 , Figure 9 and Figure 13 The battery box 100 also includes a fastener 30 for securing the wiring harness 220 to the mounting member 22.

[0135] For example, the fastener 30 includes a mounting base 31 and a cable tie 32. The mounting base 31 is installed in the mounting hole 221a; the cable tie 32 is installed in the mounting base 31 and is used to secure the wire harness 220. The cable tie 32 can limit the position of the wire harness 220. By setting the positions of the mounting member 22 and the mounting base 31, the wire harness 220 can be arranged for proper wiring. Depending on the position of the mounting hole 221a, the fastener 30 can fix the wire harness 220 at different positions on the mounting member 22.

[0136] For example, the mounting base 31 can be engaged with the mounting hole 221a, which can reduce the difficulty of disassembly and assembly.

[0137] Understandably, a cable tie 32 can bundle one or more wire harnesses 220.

[0138] In some embodiments, please refer to Figure 14 and Figure 15 The bracket body 21 has a cable passage 21a, and the mounting member 22 faces the cable passage 21a. By providing the cable passage 21a, space can be provided to avoid the wire harness 220, and the weight of the bracket body 21 can be reduced, thus reducing the overall weight of the battery box 100. The mounting member 22 is located within the cable passage 21a, which can reduce the space occupied by the wire harness 220 and improve the space utilization of the battery box 100.

[0139] The position of the mounting component 22 relative to the cable port 21a can be adapted to the wiring harness 220 layout requirements.

[0140] In some embodiments, please refer to Figures 6-11 The mounting component 22 includes a main body 221, one end of which is connected to the bracket body 21, and the other end of which is suspended. The suspended end of the main body 221 is far away from the main bracket 20, which facilitates the arrangement of the wire harness 220 at the suspended end of the main body 221 to avoid interference between the wire harness 220 and the bracket body 21.

[0141] In some embodiments, the main body 221 has a mounting hole 221a.

[0142] In some embodiments, please refer to Figures 6-11 The main body 221 includes a straight section 2211 and a bent section 2212. The mounting hole 221a is located in the straight section 2211; the bent section 2212 connects the bracket body 21 and the straight section 2211 respectively, so that the straight section 2211 extends toward the cable passage 21a.

[0143] The angle of the straight section 2211 relative to the bracket body 21 can be set by the bending section 2212, so that the straight section 2211 extends toward the wire passage 21a, so as to arrange the wire harness 220. See some embodiments for details. Figure 3 , Figure 7 and Figure 9 The bent section 2212 includes an extension area 22121 and a first rounded corner area 22122. The extension area 22121 is connected to the bracket body 21, and the first rounded corner area 22122 is connected to the extension area 22121. The inner radius of the first rounded corner area 22122 is greater than or equal to the plate thickness S0 of the mounting part 22. The straight section 2211 has an angle of 90 degrees with the bracket body 21. The straight section 2211 includes a neck area 22111 and a mounting area 22112. The neck area 22111 is connected to the first rounded corner area 22122, and the mounting area 22112 is connected to the neck area 22111. The width of the mounting area 22112 is greater than the width of the neck area 22111.

[0144] Thus, the straight section 2211 can face the connector 2101 of the battery acquisition unit 210 to facilitate fixing according to the direction of the wiring harness 220. The inner radius of the first rounded corner area 22122 is greater than or equal to the plate thickness S0 of the mounting part 22, which can reduce the possibility of cracking during the stamping of the parts, facilitate the forming of parts, reduce the scrap rate of parts, and reduce the production cost of parts.

[0145] For example, the plate thickness S0 of the mounting member 22 is 1.5 mm. The inner radius of the first rounded corner area 22122 is greater than or equal to 1.5 mm, for example, 1.8 mm, 2.0 mm, 2.2 mm or 2.5 mm, etc.

[0146] In some embodiments, please refer to Figure 15 The distance S1 between the bent section 2212 and the two ends of the support body 21 at the wire passage 21a is greater than or equal to 10mm. For example, the distance S1 between the extension area 22121 and the two ends of the support body 21 at the wire passage 21a is greater than or equal to 10mm, such as 12mm, 15mm, 18mm, or 20mm, etc. This reduces the possibility of cracking during sheet metal processing, facilitates part forming, reduces part scrap rate, and reduces part production costs.

[0147] In some embodiments, please refer to Figure 9 The distance S2 between the mounting area 22112 and the first rounded corner area 22122 is greater than or equal to 2mm, for example, 2.2mm, 2.5mm, 2.7mm, or 3mm, etc. S2 is the height of the neck area 22111. In this way, the possibility of cracking during the sheet metal processing can be reduced, the part forming can be facilitated, the scrap rate of the parts can be reduced, and the production cost of the parts can be reduced.

[0148] In some embodiments, please refer to Figure 9 and Figure 15 The distance S1 between the extension area 22121 and the bracket body 21 at both ends of the cable passage 21a is greater than or equal to 10mm, for example, 12mm, 13mm, 15mm or 18mm, etc.; the distance S2 between the mounting area 22112 and the first rounded corner area 22122 is greater than or equal to 2mm, for example, 2.2mm, 2.5mm, 2.7mm or 3mm, etc. This reduces the possibility of cracking during sheet metal processing, facilitates part forming, reduces part scrap rate, and reduces part production costs. In some embodiments, the distance between the mounting component 22 and the battery acquisition unit 210 is controlled to reduce the possibility of functional failure of the battery acquisition unit 210 due to wear between the mounting component 22 and the battery acquisition unit 210, thereby reducing the possibility of functional failure of the battery box 100 due to functional failure of the battery acquisition unit 210.

[0149] In some embodiments, please refer to Figure 9 The distance between the installation area 22112 and the battery acquisition unit 210 is greater than or equal to 3.5mm, for example, 4mm, 5mm, 6mm, 8mm or 10mm, etc.

[0150] It is understandable that the distance between the installation area 22112 and the battery acquisition unit 210 in any direction is greater than or equal to 3.5mm.

[0151] For example, the distance between the bottom of the bracket body 21 and the base plate 2103 of the battery acquisition unit 210 is 17.1 mm. In order to satisfy that the distance between the mounting area 22112 and the battery acquisition unit 210 is greater than or equal to 3.5 mm, the height S5 of the body 221 is set to be less than or equal to 13.6 mm, such as 13 mm, 12.5 mm, 12.2 mm, 11 mm or 10 mm, etc.

[0152] For example, please refer to Figure 13 The battery acquisition unit 210 includes a base plate 2103 and a side plate 2104 connected to each other, and the side plate 2104 has an inner side surface 2102.

[0153] The distance between the installation area 22112 and the base plate 2103 of the battery acquisition unit 210 is greater than or equal to 3.5mm.

[0154] In some embodiments, please refer to Figure 11 The mounting component 22 also includes a reinforcing part 222, which can improve the structural strength of the mounting component 22.

[0155] For example, please refer to Figure 11 The main body 221 is connected to reinforcing portions 222 on both sides. For example, please refer to... Figure 11 The reinforcing portion 222 is bent at least partially relative to the main body portion 221. This reduces the possibility of interference between the wire harness 220 and the reinforcing portions 222 on both sides of the main body portion 221 when the wire harness 220 is laid, and reduces the difficulty of laying the wire harness 220.

[0156] In some other embodiments not shown, the reinforcing part 222 is connected to only one side of the main body 221.

[0157] For example, the connection between the reinforcing part 222 and the main body part 221 is smoothly transitioned to prevent damage to the wire harness 220 during disassembly, assembly, handling or transportation.

[0158] In some embodiments, please refer to Figure 7 , Figure 9 and Figure 11The reinforcing part 222 includes a second rounded corner area 2221 and a flange area 2222. The flange area 2222 is connected to the mounting area 22112 through the second rounded corner area 2221. The inner radius of the second rounded corner area 2221 is greater than or equal to the plate thickness S0 of the mounting part 22. The flange length S3 of the flange area 2222 is less than or equal to 3.7mm, for example, 3.5mm, 3.2mm, 3mm, 2.5mm, 2mm or 1mm, etc.

[0159] The inner radius of the second rounded corner area 2221 is greater than or equal to the plate thickness S0 of the mounting part 22. This reduces the possibility of cracking during part stamping, facilitates part forming, reduces part scrap rate, and reduces part production cost.

[0160] When the distance between the straight section 2211 and the inner side 2102 of the battery acquisition unit 210 is 8.7mm and the inner radius of the second rounded corner area 2221 is greater than or equal to 1.5mm, in order to meet the spacing setting, the flange length S3 of the flange area 2222 is set to be less than or equal to 3.7mm, so that the distance between the mounting area 22112 and the battery acquisition unit 210 is greater than or equal to 3.5mm.

[0161] Thus, the flanged area 2222 serves to protect the wiring harness 220, reducing the possibility of the wiring harness 220 coming into contact with sharp metal edges, causing insulation failure and leakage in the battery box 100. Furthermore, the flanged area 2222 can be manufactured using materials that would otherwise need to be removed, without incurring additional material costs.

[0162] In some embodiments, please refer to Figure 2 and Figure 3 Both sides of the mounting area 22112 are connected to the reinforcing part 222. The reinforcing part 222 is bent at least partially relative to the mounting area 22112. The distance between the reinforcing part 222 and the battery acquisition unit 210 is greater than or equal to 3.5mm, such as 4mm, 5mm, 6mm or 8mm, etc.

[0163] The distance between the reinforcing part 222 and the inner side surface 2102 of the battery acquisition unit 210 is greater than or equal to 3.5mm.

[0164] In some embodiments, please refer to Figure 14 The battery device 200 also includes a control panel 230, and control panels 230 are provided on both sides of the bracket 20; the control panels 230 on both sides are electrically connected to the interface 2101 of the battery acquisition unit 210 through the wiring harness 220.

[0165] In some embodiments, please refer to Figure 14The distance between the mounting component 22 at the connection point with the bracket body 21 and the two ends of the bracket body 21 at the cable passage 21a is greater than or equal to 10mm, for example, 12mm, 15mm, 18mm, or 20mm, etc.; the horizontal distance S4 between the centerline of the mounting component 22 and the centerline of the adjacent plug interface 2101 is 10~50mm, for example, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, or 50mm, etc. If the distance between the adjacent plug interface 2101 and the mounting component 22 is too small, the bending degree of the wire harness 220 will be large when routing, making installation difficult and potentially causing significant damage to the structure of the wire harness 220, or even preventing connection. If the distance between the adjacent plug interface 2101 and the mounting component 22 is too large, the wire harness 220 will occupy too much space, which is not conducive to improving space utilization. Therefore, controlling the horizontal distance between the mounting component 22 and the adjacent connector 2101 can reduce the bending degree of the wiring harness 220 and reduce the loss of the wiring harness 220. It can be understood that the part of the mounting component 22 located at the connection of the bracket body 21 is the bending section 2212.

[0166] In some embodiments, please refer to Figure 14 and Figure 15 The mounting component 22 is connected to the side of the bracket body 21 away from the connector 2101 of the battery acquisition unit 210. The connector 2101 of the battery acquisition unit 210 is located on one side of the bracket body 21 and at the cable passage 21a. This creates a certain distance between the connector 2101 and the mounting component 22, facilitating the fixing of the wire harness 220, for example, fixing multiple sets of wire harnesses 220, to prevent the wire harness 220 from being easily damaged due to excessive bending angle.

[0167] In some embodiments, please refer to Figures 1-15The battery box 100 includes a box body 10 and a bracket 20. The box body 10 is used to hold battery modules; the bracket 20 is mounted on the box body 10. The bracket 20 includes a bracket body 21 and a mounting member 22. The bracket body 21 is used to mount the battery acquisition unit 210; the mounting member 22 has a mounting hole 221a. The battery box 100 also includes a fixing member 30, which includes a fixing seat 31 and a cable tie 32. The fixing seat 31 is mounted on the mounting hole 221a; the cable tie 32 is mounted on the fixing seat 31 and is used to fix the wire harness 220. The bracket body 21 has a wire passage 21a, and the mounting member 22 faces the wire passage 21a. The bracket body 21 includes a back plate 211 and a liner 212. The back plate 211 is mounted on the box body 10 and is used to mount the battery acquisition unit 210. The liner 212 is mounted on the back plate 211. The mounting member 22 is stamped and formed on the liner 212. The battery box 100 also includes a cover plate 40, mounted on a back plate 211, forming a receiving cavity with the back plate 211 to accommodate the battery acquisition unit 210. Specifically, the mounting member 22 is connected to the side of the bracket body 21 away from the insertion interface 2101 of the battery acquisition unit 210. The mounting member 22 includes a main body 221, one end of which is connected to the bracket body 21, and the other end of which is suspended. The main body 221 includes a straight section 2211 and a bent section 2212. A mounting hole 221a is located in the straight section 2211; the bent section 2212 connects the bracket body 21 and the straight section 2211 respectively, so that the straight section 2211 extends toward the cable passage 21a. The angle between the straight section 2211 and the bracket body 21 is 90 degrees. The mounting member 22 also includes a reinforcing part 222, which is connected to both sides of the main body 221. The reinforcing part 222 is bent at least partially relative to the main body part 221.

[0168] In this embodiment, the mounting component 22 and the liner 212 are constructed as a single molded part, eliminating the need for additional installation or welding of the mounting component 22, thus reducing processes, assembly complexity, and production efficiency. Simultaneously, there is no need to reserve operating space for the mounting component 22, resulting in a more compact and rational spatial layout, improving the space utilization of the housing 10, and reducing production costs. The mounting component 22 can organize the arrangement of the wiring harness 220, preventing it from being cluttered, occupying too much space, and hindering later maintenance. The back plate 211 provides installation space for the battery acquisition unit 210 and protects it. The liner 212 further enhances the structural strength of the bracket body 21. The cover plate 40 protects the battery acquisition unit 210, reducing the possibility of structural damage. The cable ties 32 limit the wiring harness 220, and the wiring harness 220 can be arranged rationally by setting the positions of the mounting component 22 and the fixing seat 31. By providing the cable passage 21a, space can be provided to avoid the wiring harness 220, and the weight of the bracket body 21 can be reduced, thus reducing the overall weight of the battery box 100. One end of the main body 221 is suspended away from the main bracket 20, facilitating the arrangement of the wiring harness 220 at this suspended end to prevent interference between the wiring harness 220 and the bracket body 21. The bending section 2212 allows for setting the angle of the straight section 2211 relative to the bracket body 21, causing the straight section 2211 to extend into the cable passage 21a for easier arrangement of the wiring harness 220. The straight section 2211 faces the insertion interface 2101 of the battery acquisition unit 210, facilitating fixation according to the routing of the wiring harness 220. The reinforcing section 222 improves the structural strength of the mounting member 22. The reinforcing portion 222 is bent at least partially relative to the main body portion 221, which reduces the possibility of interference between the wire harness 220 and the reinforcing portions 222 on both sides of the main body portion 221 when the wire harness 220 is laid, and reduces the difficulty of laying the wire harness 220. This also ensures a certain distance between the connector 2101 and the mounting member 22, facilitating the fixing of the wire harness 220, for example, fixing multiple sets of wire harnesses 220, to prevent the wire harness 220 from being easily damaged due to excessive bending angle.

[0169] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
