Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to an energy storage container. Background Technology

[0002] Energy storage containers are an important method for integrating energy storage equipment, combining multiple battery devices to meet the needs of large-scale energy storage. However, in energy storage system applications, battery modules are prone to static electricity buildup or abnormal leakage due to factors such as charge migration and insulation aging. When battery devices are integrated into enclosed spaces such as containers, if the charge cannot be dissipated in time, the accumulated charge may generate electric sparks when it reaches a critical point, leading to thermal runaway or even explosion of the battery. Furthermore, if external leakage occurs in the battery device, workers who accidentally come into contact with it may face the risk of electric shock.

[0003] Currently, common grounding methods for energy storage containers mainly rely on single-point grounding. Specifically, a single fixed point is selected at the bottom, side, or top of the battery unit, and the battery unit is rigidly connected to the container's metal frame using bolts, copper cables, etc., before being led to the ground. This grounding method is prone to bolt loosening and cable breakage due to vibration, corrosion, etc.; moreover, it relies on a single path to discharge charge, lacks redundancy design, and is easily interrupted due to connection failure.

[0015] As a preferred technical solution of this application, the connecting bracket includes a first bracket and a second bracket, the first bracket and the second bracket are spaced apart in a first direction, and the first bracket and the second bracket are spaced apart to form a support interval, the support interval being used to install the battery device; the first conductive element and the second conductive element are both connected to the first bracket or the second bracket.

[0016] As a preferred technical solution of this application, the battery compartment is provided with a plurality of connectors, which are spaced apart along the first direction; a plurality of bracket groups are arranged in the first direction, and the first bracket and the second bracket arranged adjacent to each other in two adjacent bracket groups are connected to the same connector.

[0017] As a preferred technical solution of this application, the connector includes a plurality of columns spaced apart along a second direction, the second direction being perpendicular to the first direction; the columns are provided with a first connecting portion, and both the first bracket and the second bracket are provided with a plurality of second connecting portions along the second direction, the plurality of second connecting portions being detachably connected to the first connecting portions of the plurality of columns, and the first connecting portion and the second connecting portion being insulated from each other.

[0032] To better understand and implement this application, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0035] See Figure 1 and Figure 2 This application discloses an energy storage container, which includes a container body 10, a plurality of connecting brackets 13, and a grounding assembly. Specifically, the container body 10 has a battery compartment 11; wherein, the plurality of connecting brackets 13 are disposed within the battery compartment 11, the connecting brackets 13 are used to install battery devices 20, and the connecting brackets 13 are provided with conductive parts. In addition, the grounding assembly includes a first conductive element 14 and a second conductive element 15, the first conductive element 14 is used to electrically connect the conductive parts to the outside of the battery device 20, and the second conductive element 15 is used to electrically connect the conductive parts of the plurality of connecting brackets 13 and to the container body 10.

[0036] Based on this structure, when using the energy storage container of this application, during assembly, the container body 10 is first assembled, the battery compartment 11 is built inside the container body 10, then several connecting brackets 13 are installed into the battery compartment 11, and then the battery device 20 is installed onto the connecting brackets 13.

[0037] Next, the grounding components are connected. Specifically, the first conductive element 14 is used to electrically connect the conductive part on the connecting bracket 13 to the outside of the battery device 20. The electrical connection can be achieved by welding or by fastening with conductive terminals and screws. Then, the second conductive element 15 is used to electrically connect the conductive parts of several connecting brackets 13 together, and the second conductive element 15 is electrically connected to the housing 10. The electrical connection between the second conductive element 15 and the conductive part and the housing 10 can also be achieved by welding or by fastening with conductive terminals and screws.

[0038] The first conductive component 14 can be made of a material with good conductivity, such as a wire or a metal sheet. It is firmly connected to the battery device 20 and the conductive parts to ensure that the static electricity or leakage current generated by the battery device 20 can be smoothly conducted to the connecting bracket 13. The second conductive component 15 can be made of a metal rod, a busbar 151, or other components. It can collect the current on each connecting bracket 13 and conduct it to the container 10, and finally ground it through the container 10 to realize the grounding function of the entire energy storage container.

[0039] Thus, the outer side of the battery device 20 is connected to the conductive part of the connecting bracket 13 through the first conductive element 14, and the conductive parts of each connecting bracket 13 are connected and electrically connected to the box 10 through the second conductive element 15, forming a current flow path. This can promptly conduct the static electricity or leakage current generated by the battery device 20 to the ground, preventing the accumulation of charge in the battery device 20 or the container, and effectively reducing safety hazards caused by poor grounding, such as electric shock to workers, electrical fires, and electric shock accidents.

[0040] It is worth noting that this application uses a first conductive element 14 to connect the connecting bracket 13 to the battery device 20, and then electrically connects each connecting bracket 13 through a second conductive element 15, which has high reliability. When one or more of the first conductive elements 14 fail, they can be easily inspected, repaired or replaced individually without affecting the grounding of other battery devices 20. This independence reduces the failure risk of the grounding system.

[0041] In addition, the housing 10 of this application is provided with panels 18 on both sides and a cover plate 19 on the top of the housing 10. By opening the panels 18, the battery compartment 11 can be accessed to disassemble, install, and repair the battery device 20 and its related control system inside the housing 10.

[0042] As a preferred technical solution of this application, see [link / reference]. Figure 5 The conductive part includes a first conductive part 133 and a second conductive part 134, and the first conductive part 133 and the second conductive part 134 are spaced apart on the connecting bracket 13 and are electrically connected to each other.

[0043] See Figure 5 The first conductive part 133 can be disposed at the end of the connecting bracket 13 and on the side of the connecting bracket 13 facing the battery device 20, so that the first conductive part 133 can be electrically connected to the surface of the battery device 20 through the first conductive member 14. The second conductive part 134 can be disposed on the connecting bracket 13 at a distance from the end and on the side of the connecting bracket 13 facing away from the battery device 20, so that the second conductive member 15 can rest against multiple connecting brackets 13 and be electrically connected to multiple second conductive parts 134.

[0044] When static electricity or leakage occurs on the surface of the battery device 20, the current flows through the first conductive element 14 to the first conductive part 133, and then flows inside the connecting bracket 13 to the second conductive part 134. Subsequently, the currents of the second conductive parts 134 on multiple connecting brackets 13 converge onto the second conductive element 15, which guides the current to the housing 10. A copper rod can be installed at the bottom of the housing 10 to connect to the ground, allowing the current in the housing 10 to ultimately flow to the ground through the copper rod.

[0045] It should be noted that the two conductive parts are interconnected and spaced apart, which effectively increases the cross-sectional area for current conduction. According to the law of resistance, under the same conditions, the larger the cross-sectional area of ​​a conductor, the lower its resistance. Therefore, this arrangement can effectively reduce the resistance of the entire grounding system, allowing static electricity or leakage current to be conducted to the ground more quickly and smoothly, further improving the efficiency and safety of grounding. Simultaneously, connecting the two conductive parts to two conductive components increases the connection area between them, making the connection between the conductive parts and components tighter and more stable.

[0046] As a preferred technical solution of this application, the connecting bracket 13 is provided with an insulating region and several exposed regions. Specifically, the insulating region is provided with an insulating layer, and the exposed regions expose the metal surface of the connecting bracket 13. Among them, the several exposed regions are formed as a first conductive part 133 and a second conductive part 134.

[0047] More specifically, an insulating layer is provided on the outer surface of the connecting bracket 13. The insulating layer can be a paint layer, an epoxy resin coating, or an insulating tape, etc. The first conductive part 133 and the second conductive part 134 are two exposed areas provided at intervals on the outer surface of the connecting bracket 13. The connecting bracket 13 does not provide an insulating layer in the exposed areas. The first conductive element 14 and the second conductive element 15 can be electrically connected to the connecting bracket 13 in the exposed areas.

[0048] It should be noted that the battery device 20 in this application can be a battery pack, battery module, etc. The connecting bracket 13 can be made of metals such as copper, aluminum, and steel, which have good conductivity and metal strength. It can not only support the battery device 20, but also ground the surface of the battery device 20 for static electricity and leakage through the first conductive element 14 and the second conductive element 15.

[0049] In this way, the contact portions between the battery device 20 and the connecting bracket 13 are separated by an insulating layer, and the battery device 20 is electrically connected to the connecting bracket 13 only through the first conductive element 14. Alternatively, the conductive part can be a conductive block or conductive sheet welded or screwed onto the connecting bracket 13, which is electrically connected to the first conductive element 14 and the second conductive element 15.

[0050] As a preferred technical solution of this application, see [link / reference]. Figure 2 and Figure 5 The first conductive element 14 includes a first wire, one end of which is electrically connected to the first conductive part 133, and the other end of which is electrically connected to the outside of the battery device 20.

[0051] Based on this structure, refer to the following when assembling: Figure 6 One end of the first wire can be connected to the conductive terminal 141, and then the conductive terminal 141 can be electrically connected to the first conductive part 133 on the connecting bracket 13. This connection process can be carried out by welding, bolting, or other methods to ensure a firm connection and good conductivity. After that, after the battery device 20 is installed on the connecting bracket 13, the other end of the first wire can also be electrically connected to the outside of the battery device 20 through the conductive terminal 141, using the same connection method as described above, to ensure that the wire is tightly connected to the outer casing of the battery device 20 and to achieve electrical conduction.

[0052] Therefore, during the operation of the battery device 20, whether it is static electricity generated during normal operation or leakage due to fault, the first conductor can guide these charges to the first conductive part 133, and then conduct them to the ground through the subsequent grounding component, thereby ensuring that the battery device 20 is in a safe grounded state and effectively avoiding safety hazards caused by charge accumulation.

[0053] Furthermore, the first conductor possesses excellent flexibility and maneuverability. During actual installation, it can be flexibly adjusted according to the relative position and layout of the battery unit 20 and the connecting bracket 13. Regardless of the different models and specifications of the battery unit 20, or the specific installation position of the connecting bracket 13 within the container, the first conductor can adapt to various installation environments through bending, extension, and other methods, meeting diverse grounding connection requirements and improving the overall flexibility and adaptability of the energy storage container design.

[0054] It should be noted that the first conductive element 14 can also be a metal conductive element such as a copper sheet or an aluminum block. By connecting its two ends to the outside of the battery device 20 and the connecting bracket 13 respectively, the static electricity and leakage current on the battery device 20 can be directed to the connecting bracket 13.

[0055] As a preferred technical solution of this application, see [link / reference]. Figure 5 as well as Figure 6 The second conductive element 15 includes a busbar 151 and a plurality of connecting pieces 152, with the plurality of connecting pieces 152 spaced apart on the busbar 151. One end of each connecting piece 152 is electrically connected to the busbar 151, and the other end of each connecting piece 152 is electrically connected to the second conductive part 134. The busbar 151 is also electrically connected to the housing 10.

[0056] Based on this structure, during assembly, the busbar 151 can be fixed to the housing 10 using methods such as welding or bolting to ensure the stability and conductivity of the connection. Then, according to the position of the second conductive part 134 on the connecting bracket 13, multiple connecting pieces 152 are installed at intervals on the busbar 151. The connection between the connecting piece 152 and the busbar 151 is usually achieved by welding or riveting to ensure good electrical conductivity between them. After completing the installation of the busbar 151 and the connecting pieces 152, the other end of the connecting piece 152 is electrically connected to the corresponding second conductive part 134 on the connecting bracket 13. This can also be done using welding or bolting to ensure a tight connection between the connecting piece 152 and the second conductive part 134, forming a complete conductive path.

[0057] During the operation of the energy storage container, when the current generated by the battery device 20 is conducted to the first conductive part 133 of the connecting bracket 13 through the first conductive part 14, the current will be conducted to the second conductive part 134 through the connecting bracket 13, and then collected on the busbar 151 through the connecting piece 152. Finally, it will be conducted to the container 10 through the busbar 151 and introduced into the ground, realizing the entire grounding process.

[0058] Multiple connecting pieces 152 are spaced apart on the busbar 151 and can be connected to the second conductive part 134 of different connecting brackets 13 respectively, effectively collecting the current on each connecting bracket 13 to the busbar 151. At the same time, the current on different connecting brackets 13 can be independently connected to the busbar 151. Even if one connecting piece 152 or connecting bracket 13 malfunctions, the other connecting pieces 152 and connecting brackets 13 can still work normally without affecting the overall grounding effect.

[0059] It should be noted that the busbar 151 can be a copper busbar, stainless steel busbar, etc., and extends in a long strip shape. The connecting piece 152 can be a copper sheet, aluminum sheet, etc. Specifically, the connecting piece 152 includes a first connecting segment and a second connecting segment, and the first connecting segment and the second connecting segment are connected at an angle. The first connecting segment can be welded or riveted to the second conductive part 134 on the connecting bracket 13, and the second connecting segment can be welded or riveted to the busbar 151. This increases the connection area between the connecting piece 152 and the connecting bracket 13 and the busbar 151, enhances the tightness of the connection, and reduces the resistance when current passes through.

[0060] Furthermore, when maintaining and repairing the energy storage container, since the connecting piece 152 is detachably connected to the busbar 151 and the connecting bracket 13, if a connecting piece 152 or the connecting bracket 13 fails, only the corresponding part needs to be disassembled and replaced individually, without the need for large-scale modifications to the entire grounding assembly.

[0061] As a preferred technical solution of this application, see [link / reference]. Figure 3 and Figure 5 The battery compartment 11 is provided with a connector 12, and the connecting bracket 13 is detachably connected to the connector 12. Among them, multiple connecting brackets 13 are arranged at intervals along the height direction of the battery compartment 11 to form a bracket group 16, and a bracket group 16 is correspondingly provided with a second conductive element 15.

[0062] Based on this structure, during assembly, the connector 12 can be installed onto the battery compartment 11 first. Then, multiple connecting brackets 13 are arranged at intervals along the height direction of the battery compartment 11 and fastened to the connector 12 to form a bracket group 16. After the bracket group 16 is installed, the corresponding second conductive component 15 is placed vertically and connected to each connecting bracket 13 of the bracket group 16. Each connecting bracket 13 is used to install the battery device 20, and the battery device 20 can be sequentially installed on each connecting bracket 13 of the bracket group 16.

[0063] Therefore, by arranging connecting brackets 13 at intervals along the height of the battery compartment 11 to form bracket groups 16, the vertical space of the battery compartment 11 can be fully utilized. This layout allows more battery devices 20 to be installed in a limited space, increasing the energy storage density of the energy storage container. At the same time, the reasonable spacing also facilitates the installation, maintenance, and heat dissipation of the battery devices 20, ensuring that the battery devices 20 can operate in a good environment.

[0064] In this system, each bracket group 16 corresponds to a second conductive element 15, making the grounding system of each bracket group 16 relatively independent yet interconnected. When a battery device 20 experiences a leakage, the connecting bracket 13 connected to it can quickly conduct the current to the ground through the corresponding second conductive element 15, preventing the leakage current from spreading throughout the system.

[0065] The connecting bracket 13 and the connector 12 can be detachably connected via bolts, clips, or other means, making the installation of the battery device 20 more flexible. Compared with traditional welding methods, this avoids the problem of the bracket's position being fixed after welding, which severely restricts the operator's space inside the cabin. When maintenance or replacement of the battery device 20 is required, the connecting bracket 13 can be easily disassembled without being restricted by the fixed welded structure, thus improving work efficiency.

[0066] Meanwhile, workers can flexibly adjust the position and layout of the bracket according to actual operational needs. When different specifications of batteries need to be installed, workers can adjust or replace the bracket according to the actual size of the battery and installation requirements, without having to redesign and manufacture the entire bracket structure as in traditional welding methods, greatly improving operational flexibility and adaptability.

[0067] As a preferred technical solution of this application, see [link / reference]. Figure 6 The connecting bracket 13 includes a first bracket 131 and a second bracket 132, and the first bracket 131 and the second bracket 132 are spaced apart in a first direction, forming a support gap for mounting the battery device 20. The first conductive element 14 and the second conductive element 15 are both connected to either the first bracket 131 or the second bracket 132.

[0068] Based on this structure, during assembly, the first bracket 131 and the second bracket 132 of the connecting bracket 13 are first arranged at intervals in the first direction to form a support interval for mounting the battery device 20. The width of the support interval is adapted to the size of the battery device 20 to ensure that the battery device 20 can be stably installed. Subsequently, the battery device 20 is placed in the support interval, so that the battery device 20 is tightly fitted with the first bracket 131 and the second bracket 132. After the battery device 20 is installed, the connection of the first conductive element 14 and the second conductive element 15 is performed.

[0069] If the first conductive element 14 and the second conductive element 15 are connected to the first bracket 131, one end of the first conductive element 14 needs to be connected to the conductive part on the first bracket 131, and the other end needs to be connected to the outside of the battery device 20; at the same time, the connecting piece 152 of the second conductive element 15 is connected to the second conductive part 134 of the first bracket 131, and the busbar 151 is connected to the housing 10. If connected to the second bracket 132, the operation method is similar.

[0070] When the energy storage container is in operation, when the battery device 20 generates static electricity or leakage, the current is first conducted through the first conductive element 14 to the conductive part of the first support 131 or the second support 132, then conducted through the support to the second conductive part 134, and then collected by the second conductive element 15 and conducted to the container body 10, and finally led to the ground.

[0071] Thus, the support interval formed by the first bracket 131 and the second bracket 132 provides a stable and reliable support structure for the battery device 20, which can effectively distribute the weight of the battery device 20, reduce the pressure on a single bracket, and ensure the stable placement of the battery device 20 inside the container.

[0072] The first conductive component 14 and the second conductive component 15 are both connected to the first bracket 131 or the second bracket 132. On the one hand, this reduces the length and complexity of the conductive lines, lowers the resistance, and improves the efficiency of current conduction. On the other hand, the centralized connection method facilitates installation, maintenance, and repair, allowing staff to more easily inspect and replace the conductive components, thus reducing maintenance costs and time.

[0073] As a preferred technical solution of this application, see [link / reference]. Figure 3 and Figure 4 The battery compartment 11 is provided with multiple connectors 12, and the multiple connectors 12 are spaced apart along a first direction. At the same time, multiple bracket groups 16 are arranged in the first direction, and the first bracket 131 and the second bracket 132 of two adjacent bracket groups 16 are connected to the same connector 12.

[0074] Based on this structure, during assembly, multiple connectors 12 are first installed inside the battery compartment 11, with the connectors 12 spaced apart in the first direction. Next, multiple bracket groups 16 are arranged sequentially in the first direction. When installing adjacent bracket groups 16, adjacent first brackets 131 and second brackets 132 are connected to the same connector 12, typically using detachable connections such as bolts or clips, ensuring a secure and stable connection. After completing the installation of the bracket groups 16, the battery device 20 is installed within the support intervals of the bracket groups 16, and the first conductive element 14 and the second conductive element 15 are connected, forming a complete circuit between the battery device 20 and the grounding component.

[0075] Thus, multiple connectors 12 are spaced apart along the first direction, and the first support 131 and the second support 132 of adjacent support groups 16 are connected to the same connector 12, so that the support groups 16 are interconnected and form a stable overall structure. This can effectively distribute the weight of the battery device 20 and the support group 16, enhance the stability of the internal structure of the entire energy storage container, and reduce the risk of structural deformation and damage caused by external forces such as vibration and impact during transportation and use.

[0076] Meanwhile, multiple connectors 12 and bracket groups 16 are arranged at intervals along the first direction, which can make full use of the space of the battery compartment 11, so that more bracket groups 16 and battery devices 20 can be installed in the limited space of the battery compartment 11, thereby increasing the energy storage density of the energy storage container and meeting the demand for large-capacity energy storage.

[0077] As a preferred technical solution of this application, the connector 12 includes a plurality of columns 122 spaced apart along a second direction, which is perpendicular to the first direction. Each column 122 has a first connecting portion 121, and both the first support 131 and the second support 132 have a plurality of second connecting portions 135 along the second direction. The plurality of second connecting portions 135 are detachably connected to the first connecting portions 121 of the plurality of columns 122, and the first connecting portions 121 and the second connecting portions 135 are insulated from each other.

[0078] Based on this structure, during assembly, the columns 122 with the first connecting parts 121 are first installed in the battery compartment 11 along the second direction, ensuring that the columns 122 are evenly spaced. Then, the first bracket 131 and the second bracket 132 are arranged at intervals along the first direction, while aligning the multiple second connecting parts 135 of these brackets along the second direction with the first connecting parts 121 on the columns 122. Using fasteners 136 such as bolts and nuts, the second connecting parts 135 are connected to the first connecting parts 121, completing the installation and fixation of the connecting bracket 13 and the connecting member 12.

[0079] Both the second connecting portion 135 and the first connecting portion 121 can be connecting holes, and the contact area between the second connecting portion 135 and the first connecting portion 121 is provided with an insulating layer, specifically a paint layer. The fastener 136 can be a metal screw, and a layer of paint is sprayed on the outer surface of the metal screw to keep the first connecting portion 121 and the second connecting portion 135 insulated, thus preventing accidental conduction of current.

[0080] It should be noted that the first direction can be the length direction of the battery compartment 11, and the second direction is the width direction of the battery compartment 11.

[0081] Because the connector 12 uses multiple columns 122 spaced apart along the second direction, and the columns 122 are connected to the connecting bracket 13 via a detachable first connecting part 121 and a second connecting part 135, the installation position and angle of the connecting bracket 13 can be flexibly adjusted according to actual needs. If it is necessary to replace the battery device 20 with a different specification, the connecting bracket 13 can be easily disassembled and reinstalled in a suitable position, improving the versatility and scalability of the energy storage container.

[0082] Multiple columns 122 and multiple connecting parts on the connecting bracket 13 cooperate with each other. The columns 122, which are spaced apart along the second direction, provide multiple support points for the connecting bracket 13, which can effectively distribute the weight of the battery device 20 and the connecting bracket 13 and enhance the stability of the entire structure.

[0083] In addition, the connector 12 also includes a crossbeam 123, the bottom of a plurality of columns 122 is mounted on the bottom plate 101 of the housing 10, the top of the plurality of columns 122 is connected to a crossbeam 123, and the crossbeam 123 is mounted on the top of the battery compartment 11.

[0084] As a preferred embodiment of this application, both the first support 131 and the second support 132 are L-shaped supports. (See reference...) Figure 2 and Figure 5 The bottom of the first bracket 131 and the second bracket 132 is also provided with a reinforcing frame 17, which is connected to the connector 12 and supported on the bottom of the first bracket 131 or the second bracket 132.

[0085] Specifically, the L-shaped bracket includes a first support section extending vertically and a second support section extending horizontally. The first and second support sections are connected at right angles, and the cross-sectional shape is L-shaped. During assembly, the reinforcing frame 17 can be connected to the connector 12 of the battery compartment 11 using bolts, welding, or other methods. Then, the first bracket 131 or the second bracket 132 is placed on the reinforcing frame 17, ensuring that the bottom of the first bracket 131 or the second bracket 132 is in contact with the reinforcing frame 17. Finally, the first bracket 131 and the second bracket 132 are connected to the connector 12.

[0086] Specifically, the first support section can be securely connected to the connection holes on the column 122 through multiple connection holes on it. The bottom sides of the battery device 20 are respectively placed on the second support sections of the first bracket 131 and the second bracket 132, which can prevent the battery device 20 from shaking and causing risks such as loosening of connections or damage.

[0087] The reinforcing frame 17 can be an L-shaped connecting piece 152, which includes a first reinforcing section extending vertically and a second reinforcing section extending horizontally. The first and second reinforcing sections are connected at right angles, and the cross-sectional shape is L-shaped. Specifically, the first reinforcing section is connected to the connector 12, and the second reinforcing section abuts against the bottom of the first bracket 131 or the second bracket 132.

[0088] Meanwhile, multiple reinforcing frames 17 can be provided along the extension direction of the first bracket 131 or the second bracket 132, with the multiple reinforcing frames 17 spaced apart and supported at the bottom of the first bracket 131 or the second bracket 132.

[0089] In addition, the connecting bracket 13 can also be an integral bracket that supports the bottom of the battery device 20 as a whole, with at least two ends of the bracket detachably mounted on the column 122.

[0090] Since the battery device 20 is typically heavy, the first support 131 and the second support 132 need to withstand enormous pressure during long-term operation. This application connects the reinforcing frame 17 to the connector 12 and supports the bottom of the support, effectively distributing the weight borne by the support and greatly increasing its load-bearing capacity.

[0091] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
