In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0050] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0051] The term "plurality" used in this application refers to two or more (including two).

[0052] In this application, battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application do not limit this. Battery cells may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of this application do not limit this. Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0053] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or a battery pack. A battery generally includes a housing that encloses one or more battery cells or multiple battery modules. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0054] A battery includes a casing, an electrode assembly, and an electrolyte. The casing is used to hold the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. The battery operates primarily by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, and the uncoated positive electrode collector serves as the positive electrode tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode collector. The uncoated negative electrode collector protrudes from the coated negative electrode collector, and the uncoated negative electrode collector serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon, etc. In order to ensure that a large current can pass without melting, the positive electrode tabs are multiple and stacked together, and the negative electrode tabs are multiple and stacked together.

[0055] The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0056] In recent years, batteries have played an irreplaceable and important role in the battery industry as the power source for electrical devices. Typically, a battery consists of a housing and multiple cells housed within it. As a core component of electrical devices, batteries have high requirements for both safety and cycle life.

[0057] In general batteries, in order to obtain sufficient power, multiple battery cells are usually stacked in an arrangement within the battery housing to form a battery pack. However, the battery cells generate a large amount of heat during the continuous charging and discharging process, which causes the internal temperature of the battery to rise. The battery pack structure in which multiple battery cells are stacked will aggravate this phenomenon, which in turn seriously affects the performance and service life of the battery, and may even cause major safety hazards during the use of the battery, which is not conducive to the safety of consumers. Therefore, in the prior art, the battery pack is usually designed as a double-layer module structure, and a double-layer module bracket is constructed to support the battery pack. This design significantly increases the storage capacity of the battery pack. However, the existing double-layer module bracket of the battery pack has many bracket components, which are prone to interference during installation, making installation difficult, time-consuming and labor-intensive.

[0058] Based on the above considerations, and to address the issue of battery cooling bracket assemblies having numerous components and being difficult to assemble, which hinders their widespread adoption and use, the inventors, after in-depth research, have designed a bracket assembly for a battery, a battery, and an electrical device, comprising a connecting portion, a first supporting portion, and a second supporting portion. The first supporting portion is used to support and secure the battery, the second supporting portion is used to secure the bracket assembly to a predetermined position, and the connecting portion is used to connect the first and second supporting portions.

[0059] In a battery holder assembly of this structure, the first support portion is connected to the battery by fastening with fasteners to form a whole. The complete holder assembly and battery matching structure are fixed to the electrical equipment through the second support portion. The overall structure has few parts and is easy to process and assemble.

[0060] The battery disclosed in the embodiments of this application can be used, but is not limited to, in electrical equipment such as vehicles, ships, or aircraft. A power supply system comprising the battery holder assembly disclosed in this application, batteries, and the like can be used to expand the scope of application of the battery holder assembly and reduce the difficulty of assembly.

[0061] The embodiments of the present application provide an electric device that uses a battery as a power source. The electric device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0062] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0063] Please refer to Figure 1, which is a schematic structural diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be provided at the bottom, head or tail of the vehicle 1000. The battery 100 can be used to power the vehicle 1000. For example, the battery 100 can serve as an 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 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0064] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0065] Please refer to Figure 2, which is a structural diagram of the battery 100 provided in some embodiments of the present application. Among them, the battery module 10 has two layers, the first layer of battery modules 10 is fixed on the first support part 11 of the bracket assembly 1, and the second layer of battery modules 10 is fixed above the water-cooling plate 400 of the bracket assembly 1. As shown in Figure 2, each battery module 10 can be provided with a plurality of battery cells 1001. In the battery 100, the plurality of battery cells 1001 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the plurality of battery cells 1001 are both connected in series and in parallel. The plurality of battery cells 1001 can be directly connected in series, in parallel, or in mixed connection, and then the battery module 10 composed of the plurality of battery cells 1001 is fixed on the bracket assembly 1. The battery 100 may also include other structures. For example, the battery 100 may also include a busbar component for realizing electrical connection between the plurality of battery cells 1001.

[0066] Please refer to Figure 3, which is a schematic diagram of the partial structure of each layer of battery modules 10 in the battery 100 provided in some embodiments of the present application. The battery 100 includes multiple rows of battery cells 1001, and the multiple rows of battery cells 1001 are arranged along the X direction. Each row of battery cells 1001 includes multiple battery cells 1001 arranged along the Y direction. The X direction and the Y direction are respectively the length direction and the width direction of the battery module 10, and the X direction and the Y direction are perpendicular to each other. Each battery cell 1001 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 thereto. The battery cell 1001 can be cylindrical, flat, rectangular or other shapes. For example, in Figure 3, the shape of the battery cell 1001 is cylindrical.

[0067] According to the present application, the bracket assembly 1 includes a connecting portion 13, a first supporting portion 11 and a second supporting portion 12, and the connecting portion 13 is formed with a first connecting surface and a second connecting surface that deviate from each other in the thickness direction; the first supporting portion 11 is arranged on the first connecting surface, and the second supporting portion is arranged on the second connecting surface, and the first supporting portion and the second supporting portion 12 extend in directions away from each other.

[0068] In the above description, the first support portion 11 can be understood as a structure extending away from the connecting portion 13 at one end of the connecting portion 13, which can be used to fix the battery module 10, and the fixing method can be bolt connection, snap fit, etc.; the second support portion 12 can be understood as a structure extending away from the connecting portion 13 at the other end of the connecting portion 13. It should be noted that in the solution of the present application, the extension direction of the second support portion and the first support portion should be set in opposite directions. This section of structure can be used to fix the bracket assembly to the electrical equipment or other places where the battery of the solution of the present application needs to be used; and the connecting portion 13 can be understood as a structure that connects the above-mentioned first support portion 11 and the second support portion 12 together. The provision of the connecting portion 13 can strengthen the connection relationship between the two, ensuring that when the battery module 10 is matched with the first support portion 11, it can be fixed to the preset position in the electrical equipment through the second support portion 12.

[0069] According to one embodiment of the present application, as shown in FIG4 , a bracket assembly 1 is provided with a connecting portion 13 as a connecting support for the bracket itself. First and second connecting surfaces are formed in the thickness direction of the connecting portion 13, which is understood as the first direction in FIG4 . The bracket assembly 1 is provided with a first support portion 11 and a second support portion 12 on the first and second connecting surfaces, respectively. The first support portion 11 is used to support the battery module 10, and the second support portion 12 is used to secure the bracket assembly 1 to a predetermined position, thereby improving the stability of the bracket assembly when securing the battery. Furthermore, the connecting portion 13 connects the first and second support portions 11, enhancing the structural strength of the bracket assembly 1. Furthermore, the first support portion 12 extends in directions away from the first support portion 11. This design ensures that when the bracket assembly 1 is in use, the first support portion 11 and the second support portion 12 do not interfere with each other during battery securing. The securing operation of the bracket assembly 1 to the predetermined position is not obstructed by the battery securing position, reducing the complexity of the installation process of the bracket assembly 1 and making it more convenient.

[0070] According to one embodiment of the present application, the projections of the first support portion 11 and the second support portion in the extension direction of the connecting portion 13 are staggered. Since the first support portion 11 and the second support portion 12 are respectively arranged on the first connecting surface and the second connecting surface, the construction method of the two will affect the installation and fixation of the bracket assembly 1. As shown in Figure 5, specifically, the projections of the first support portion 11 and the second support portion 12 in the extension direction of the connecting portion 13 are staggered. Under the premise that the components of the fixed battery do not interfere with the components of the indefinite bracket assembly 1, this design can reduce the space occupied by the bracket assembly in the thickness direction of the connecting portion 13. The thickness direction here can be understood as the first direction in Figure 4, making the bracket assembly 1 more convenient to install and fix.

[0071] According to one embodiment of the present application, the first support portion 11 is provided with a first mounting portion 111, and the second support portion 12 is provided with a second mounting portion 121. The projections of the first mounting portion 111 and the second support portion 12 in the direction of extension of the connecting portion 13 are arranged in an interlaced manner, and the second mounting portion 121 is arranged in an interlaced manner with the projection of the first support portion 11 in the direction of extension of the connecting portion 13. Specifically, the bracket assembly 1 is provided with the first mounting portion 111 on the first support portion 11, and the first mounting portion 111 is used to securely mate the battery with the bracket assembly 1; at the same time, the bracket assembly 1 is provided with the second mounting portion 121 on the second support portion 12, and the second mounting portion 121 is used to secure the bracket assembly 1 to a predetermined position.

[0072] As shown in Figures 4 and 5, in some instances, the first mounting portion 111 and the second mounting portion 121 are respectively arranged to be staggered with the projections of the second support portion 12 and the first support portion 11 in the extension direction of the connecting portion 13. The extension direction here can be understood as the third direction of Figure 5. When the battery module 10 is matched with the bracket assembly 1, the parts of the first mounting portion 111 that fix the battery will not interfere with the second mounting portion 121. At the same time, the parts of the second mounting portion 121 that are used to fix the bracket assembly 1 to the preset position will not contact the first mounting portion 111. When the bracket assembly 1 is fixed to the preset position, its fixing process will not be blocked by the fixed battery module 10, thereby improving the convenience of assembling the battery module 10 and the bracket assembly 1.

[0073] According to one embodiment of the present application, the first support portion 11 and the second support portion 12 are respectively disposed at both ends of the length direction of the connecting portion 13. As shown in FIG5 , specifically, one end of the connecting portion 13 is connected to the first support portion 11 in the extension direction (the extension direction here can be understood as the third direction in FIG5 ), and the other end is connected to the second support portion 12. The first support portion 11 and the second support portion 12 extend in directions away from each other, thereby achieving a staggered arrangement of the projections of the first support portion 11 and the second support portion 12 in the extension direction of the connecting portion 13. At the same time, the connecting portion 13 separates the first support portion 11 from the second support portion 12, reserving sufficient safety space for the installation of the second layer of battery modules 10 in the two-layer battery module 10, thereby improving the safety of the battery modules 10 after assembly.

[0074] According to one embodiment of the present application, the bracket assembly 1 further includes a reinforcing plate 14, which extends in the length direction of the connecting portion 13. The length direction here can be understood as the third direction in Figure 5, and the reinforcing plate 14 is connected to at least one of the first support portion 11 or the second support portion 12. Since the bracket assembly 1 will be used in some power equipment after being matched with the battery module 10, when the equipment is working, the vibration generated by the equipment will act on the bracket assembly 1, affecting the stability of the bracket assembly 1. As shown in Figure 5, in some instances, the bracket assembly 1 is further provided with a reinforcing plate 14, which is provided on the connecting portion 13, and the reinforcing plate 14 is connected to at least one of the first support portion 11 and the second support portion 12, thereby strengthening the structural strength of the bracket assembly 1, improving the reliability of the bracket assembly 1 and the overall stability of the bracket assembly 1 after being matched with the battery module 10, thereby improving the safety of the battery.

[0075] According to one embodiment of the present application, the reinforcing plate 14 is constructed as two, respectively provided as a first reinforcing plate 141 and a second reinforcing plate 142. The first reinforcing plate 141 is provided on the first connection surface, and its thickness direction is parallel to the first connection surface; the second reinforcing plate 142 is provided on the second connection surface, and its thickness direction is parallel to the second connection surface. The thickness direction here can be understood as the second direction in Figure 5. Because the bracket assembly 1 and the battery module 10 are used in some power equipment after being combined, the vibration generated by the equipment during operation will act on the bracket assembly 1, affecting the stability of the bracket assembly 1. However, a single reinforcing plate 14 is difficult to ensure the structural strength of the bracket assembly 1.

[0076] As shown in Figure 5, in some instances, the reinforcing plate 14 is constructed as a first reinforcing plate 141 and a second reinforcing plate 142.
