[0043] The present application proposes a battery 1000, which includes a battery cell 1 and a mounting bracket 2. The battery cell 1 includes a battery cell body 11 and a tab 12. The battery cell body 11 includes a first end 11A and a second end 11B arranged opposite to each other in a first direction Z. The tab 12 extends from the first end 11A of the battery cell body 11; the mounting bracket 2 is fixedly arranged at the first end 11A of the battery cell body 11.

[0044] The battery further includes an output structure, which is disposed on the mounting bracket 2 and connected to the tab 12 , and is configured to supply power to an electrical device.

[0045] Among them, a mounting bracket 2 is provided to be fixedly connected to the battery cell 1, and an output structure is provided on the mounting bracket 2, so that the battery cell body 11 can supply power to the electrical equipment through the output structure; and at least one of the mounting bracket 2 and the output structure is fixed to the electrical equipment, so that the battery cell 1 is not directly fixed to the electrical equipment, thereby avoiding damage to the battery cell 1 during replacement and disassembly.

[0046] Example 1

[0047] Please refer to Figures 1 to 3. The output structure includes a first protective plate 3, which is mounted on the mounting bracket 2 and connected to the electrode ear 12. The first protective plate 3 includes an output portion 31, which is arranged on a side of the mounting bracket 2 away from the battery cell body 11 in the first direction Z; wherein the mounting bracket 2 is configured to be clamped and fixed to the electrical equipment.

[0048] In an embodiment of the present application, a mounting bracket 2 is provided to be fixedly connected to the battery cell 1, and then the mounting bracket 2 is clamped and fixed to the electrical equipment, so that the battery cell body 11 can supply power to the electrical equipment through the output part 31 on the first protective plate 3; wherein, the structural form of clamping and fixing the mounting bracket 2 to the electrical equipment makes it convenient to disassemble and assemble the battery 1000 on the electrical equipment, and the battery cell body 11 is fixed to the electrical equipment through the mounting bracket 2, that is, the battery cell body 11 is not directly fixed to the electrical equipment, thereby avoiding damage to the battery cell 1 during replacement and disassembly.

[0049] The first protection plate 3 connects the electrical device and the cell body 11, and can provide overcharge protection, over-discharge protection, overcurrent protection, and short circuit protection for the cell body 11. It should be explained that the tabs 12 of the present application include positive tabs and negative tabs.

[0050] Furthermore, the method by which the mounting bracket 2 is secured to the electrical device is not limited. In one embodiment of the present application, the battery 1000 further includes at least one protrusion 4 extending from the mounting bracket 2. Specifically, the mounting bracket 2 secures the battery 1000 to the electrical device by engaging the protrusion 4 with the first engaging portion on the electrical device. The protrusion 4 can be positioned anywhere on the mounting bracket 2. Referring to FIG. 1 , the protrusion 4 is positioned on one of two opposing sides of the mounting bracket 2 in the second direction X. The protrusion 4 engages with the first engaging portion on the electrical device, thereby securing the battery 1000 within the electrical device. Since the battery 1000 has a certain length in the second direction X, in this embodiment, the mounting bracket 2 is provided with protrusions 4 on both sides in the second direction X to ensure a secure fixation of the battery 1000 within the electrical device. It should be noted that the shape of the protrusion 4 is not limited and can be polygonal, quasi-circular, cylindrical, or a special-shaped structure.

[0051] In another embodiment of the present application, the mounting bracket 2 may further include a slot 5. The slot 5 engages with a second engaging portion on the electrical device to secure the battery 1000 to the electrical device. The slot 5 is not limited to any location on the mounting bracket 2. Referring to Figures 15 and 16, the slot 5 is located on one of two opposing sides of the mounting bracket 2 in the third direction Y. The slot 5 engages with the second engaging portion on the electrical device, thereby securing the battery 1000 within the electrical device. Since the battery 1000 has a certain length in the second direction X, in this embodiment, the mounting bracket 2 is provided with two slots 5 on one side in the third direction Y, spaced apart in the second direction X. It should be noted that the shape of the slot 5 is not limited and may be a polygonal structure, a quasi-circular structure, or a special-shaped structure. The slot 5 may or may not extend through the mounting bracket 2.

[0052] In some embodiments of the present application, a card slot 5 and a protrusion 4 may be provided on the mounting bracket 2 at the same time.

[0053] Please refer to Figures 2, 5 and 13. In some embodiments of the present application, the mounting bracket 2 includes a first frame 21, the first frame 21 includes a first side 21A and a second side 21B opposite to each other in the first direction Z, and the output part 31 is overlapped on the first side 21A; the first protective plate 3 also includes a first sub-board 32 connected to the output part 31, the first sub-board 32 is arranged between the first frame 21 and the battery cell body 11, and is connected to the pole ear 12; an avoidance hollow 6 is provided on the first frame 21, and the avoidance hollow 6 passes through the first frame 21 in the first direction Z, and one end of the first sub-board 32 connected to the output part 31 is accommodated in the avoidance hollow 6. That is, in this embodiment, the output part 31 is connected to the electrode ear 12 through the first sub-plate 32, and the first sub-plate 32 is located between the first frame 21 and the battery cell body 11. Since the output part 31 needs to be exposed on the outer surface of the battery 1000 and electrically connected to the electrical equipment, that is, the output part 31 is located on the first side 21A of the first frame 21, in order to enable the output part 31 located on the first side 21A of the first frame 21 and the first sub-plate 32 located between the second side 21B of the first frame 21 and the first end 11A of the battery cell body 11 to be connected to each other, an avoidance hollow 6 is further provided on the first frame 21, that is, the output part 31 and the first sub-plate 32 are connected at the avoidance hollow 6, thereby realizing the connection between the output part 31 and the battery cell body 11. Among them, the first frame 21 and the battery cell body 11 are respectively located on both sides of the first sub-board 32 in the first direction Z, that is, the projection of the first sub-board 32 in the first direction Z falls on the battery cell body 11 or the first frame 21, thereby achieving protection for both sides of the first sub-board 32 in the first direction Z.

[0054] It should be noted that, in one embodiment of the present application, a through hole may be provided on the first frame 21 to form an avoidance hollow 6; in another embodiment of the present application, please refer to Figure 10, since the first frame 21 is extended in the plane where the second direction X and the third direction Y are located, a hollow may also be provided at the peripheral position of the first frame 21 in the plane where the second direction X and the third direction Y are located to form an avoidance hollow 6.

[0055] Referring to Figures 3 and 13 , in some embodiments of the present application, the mounting bracket 2 is provided with a lap groove 14 on the first side 21A. The lap groove 14 communicates with the avoidance hollow 6, and the output portion 31 is located within the lap groove 14. The lap groove 14 communicates with the avoidance hollow 6, and the connecting area between the avoidance hollow 6 and the lap groove 14 is arc-shaped to prevent scratching of the first protective plate 3.

[0056] In some embodiments of the present application, the depth of the overlapping groove 14 in the first direction Z is greater than the height of the output portion 31 in the first direction Z. It is understandable that the output portion 31 is located in the overlapping groove 14 and is protected by the peripheral sidewalls of the overlapping groove 14 in the second direction X and the third direction Y, thereby avoiding the risk of short circuit of the output portion 31.

[0057] Please refer to Figures 10 to 12. In some embodiments of the present application, the battery cell 1 also includes a first limiting portion 131, which extends from the first end 11A of the battery cell body 11, and the tab 12 is arranged on a side of the first limiting portion 131 that is away from the battery cell body 11 in the first direction Z; the mounting bracket 2 also includes a second frame 22, which is arranged on the second side 21B of the first frame 21, wherein the first limiting portion 131 and the second frame 22 are spaced from each other in the third direction Y to form a first limiting space 19, and the first limiting space 19 is configured to accommodate the first sub-board 32. That is, in this embodiment, the first sub-board 32 is limitedly installed by forming a first limiting space 19 between the first limiting portion 131 and the second frame 22 when the mounting bracket 2 is assembled to the battery cell 1; at the same time, in the third direction Y, the first sub-board 32 is located between the second frame 22 and the first limiting portion 131, so that the first sub-board 32 in the third direction Y can be protected by the second frame 22 and the first limiting portion 131.

[0058] It is understandable that, to ensure that the second frame 22 and the first limiting portion 131 have a better protection effect on the first sub-board 32 , the projection of the first sub-board 32 in the third direction Y falls on the first limiting portion 131 or the second frame 22 .

[0059] Referring to Figures 4, 5, 7, and 8, in some embodiments of the present application, the battery cell 1 further includes two second limiting portions 132, located on either side of the battery cell body 11 in the second direction X. Both second limiting portions 132 extend from the battery cell body 11 and extend toward the first frame 21 in the first direction Z. A second limiting space 20 is formed between the two second limiting portions 132, and the second limiting space 20 is configured to accommodate the second frame 22. In this embodiment, the second frame 22 is positioned and installed by the second limiting space 20 formed between the two second limiting portions 132. Furthermore, in the second direction X, the second frame 22 is located between the two second limiting portions 132, thereby limiting the movement of the second frame 22 in the second direction X. This limits the movement of the mounting bracket 2 in the second direction X after it is installed on the battery cell 1.

[0060] In order to ensure that the two second limiting portions 132 have a limiting effect on the second frame 22 in the second direction X, each second limiting portion 132 is further extended along the third direction Y to increase the contact area between the second limiting portion 132 and the second frame 22, thereby further preventing the second frame 22 from escaping from the second limiting space 20 in the second direction X.

[0061] Referring again to Figures 10 to 12 , in some embodiments of the present application, the mounting bracket 2 further includes a third frame 23 , which is disposed on a side of the first limiting portion 131 facing away from the second frame 22 in the third direction Y. That is, in addition to the second frame 22 and the first limiting portion 131 being disposed opposite each other in the third direction Y, in this embodiment, the third frame 23 is additionally provided. The third frame 23 and the second frame 22 are respectively located on opposite sides of the first limiting portion 131 in the third direction Y, thereby limiting the movement of the mounting bracket 2 along the third direction Y after being installed on the battery cell 1 .

[0062] Furthermore, the first limiting portion 131 and the second limiting portion 132 can be separate or integrated. In one embodiment of the present application, the first limiting portion 131 and the second limiting portion 132 are integrated. The first limiting portion 131 and the second frame 22 are arranged relative to each other in the third direction Y, and the first sub-plate 32 is located within the first limiting space 19 between the first limiting portion 131 and the second frame 22. The two second limiting portions 132 are arranged relative to each other in the second direction X, and the first sub-plate 32 is also located between the two second limiting portions 132. The first frame 21 and the battery cell body 11 are arranged relative to each other in the first direction Z, and the first sub-plate 32 is located between the first frame 21 and the battery cell body 11. This ensures full protection for the first sub-plate 32 and the contact connection between the tab 12 and the first sub-plate 32.

[0063] Referring to Figure 5 , the second frame 22 includes two sub-frames 221 spaced apart in the second direction X and connected to the first frame 21. By separating the second frame 22 into two sub-frames 221, the space between the two sub-frames 221 exposes a portion of the first sub-board 32, thereby providing a certain amount of clearance for components on the first sub-board 32.

[0064] Similarly, referring to Figures 5, 6 and 14, based on the embodiment in which the second frame 22 includes two sub-frames 221, the two sub-frames 221 are in contact with the two second limiting portions 132, thereby cooperating to achieve the limiting function of the battery cell 1 on the mounting bracket 2 in the second direction X.

[0065] As will be appreciated, since portions of the first sub-board 32 may be exposed from the space between the two sub-frames 221, to protect the portion of the first sub-board 32 exposed in the space between the two sub-frames 221, as shown in Figures 4 and 13, in some embodiments of the present application, the battery 1000 further includes a gasket 7 disposed between the two sub-frames 221; at least a portion of the first sub-board 32 is located between the gasket 7 and the first stopper 131. In other words, in this embodiment, the gasket 7 is provided to shield and protect the exposed portion of the first sub-board 32. As will be appreciated, the thickness of the gasket 7 in the third direction Y is less than the thickness of the sub-frame 221 in the third direction Y. Therefore, when assembled between the two sub-frames 221, the gasket 7 does not protrude from between the two sub-frames 221 in the third direction Y, thereby improving the aesthetics of the gasket 7 after assembly.

[0066] Referring to Figures 2, 9, and 13, in some embodiments of the present application, the battery 1000 further includes a first connector 8, which is disposed between the tab 12 and the first sub-plate 32. The tab 12 is connected to the first sub-plate 32 via the first connector 8. In other words, in this embodiment, the first connector 8 enables electrical connection between the tab 12 and the first protective plate 3. Since the tabs 12 include a positive tab 12 and a negative tab 12, two first connectors 8 are also provided in this embodiment.

[0067] Referring to Figures 2, 9, 12, and 13, in some embodiments of the present application, the first connector 8 includes a first sub-connection portion 81 and a second sub-connection portion 82 that are interconnected. At least a portion of the first sub-connection portion 81 and at least a portion of the second sub-connection portion 82 are spaced apart in the third direction Y. The first sub-connection portion 81 is connected to the tab 12, and the second sub-connection portion 82 is connected to the first sub-plate 32. In other words, in this embodiment, the first connector 8 is bent to form the first sub-connection portion 81 and the second sub-connection portion 82 that are spaced apart in the third direction Y, thereby connecting the first sub-plate 32 and the tab 12 that are spaced apart in the third direction Y. Furthermore, the second sub-connection portion 82 is connected to the first sub-plate 32, thereby increasing the contact area between the second sub-connection portion 82 and the first sub-plate 32, thereby reducing the resistance at the connection between the second sub-connection portion 82 and the first sub-plate 32.

[0068] In some embodiments of the present application, at least a portion of the second sub-connection portion 82 is disposed opposite the tab 12 in the third direction Y. The battery 1000 further includes an insulating member 9 disposed between the second sub-connection portion 82 and the tab 12. In other words, in this embodiment, since the second sub-connection portion 82 needs to extend a certain distance in the first direction Z to connect with the first sub-plate 32, and at least a portion of the second sub-connection portion 82 is disposed opposite the tab 12 in the third direction Y, the insulating member 9 is provided to insulate the second sub-connection portion 82 from the tab 12, thereby preventing direct contact between the second sub-connection portion 82 and the tab 12, which could cause a short circuit in the battery 1000. It is understood that if part of the second sub-connection portion 82 contacts the tab 12, a loop circuit will be formed between the tab 12, the first sub-connection portion 81, and the second sub-connection portion 82. As a result, the current flowing out of the cell body 11 will not flow along the first and second sub-connection portions 81, 82 to the first protective plate 3 and then be output from the output portion 31, thereby causing a short circuit in the battery 1000. The insulating member 9 is insulating tape. To improve its insulating effect, the insulating tape is located between the second sub-connection portion 82 and the tab 12 and is folded twice.

[0069] Please refer to Figure 12. In some embodiments of the present application, the first sub-connection portion 81 includes an interconnected tab connection portion 811 and a bending portion 812. The tab connection portion 811 is connected to the tab 12. The bending portion 812 is bent toward the third direction Y from the end of the tab connection portion 811 away from the tab 12. The bending portion 812 is connected to the second sub-connection portion 82. The first frame 21 is provided with a groove 10 on the second side 21B, and the bending portion 812 is located in the groove 10. That is, in this embodiment, a bending portion 812 is provided to bend toward the third direction Y and connect the second sub-connection portion 82, so that at least a portion of the second sub-connection portion 82 and the first sub-connection portion 81 can be spaced apart in the third direction Y; wherein, since the bending portion 812 is located at the end of the pole tab connection portion 811 away from the pole tab 12, and at least a portion is extended in the first direction Z, in order to shorten the distance of the battery 1000 in the first direction Z and improve the compactness of the internal structure of the battery 1000, in this embodiment, a groove 10 is provided on the second side 21B of the first frame 21, and the groove 10 provides a certain accommodating space for the bending portion 812, thereby improving the compactness of the internal structure of the battery 1000, and at the same time, there is no need to adjust the relative position between the mounting bracket 2 and the battery cell 1, thereby shortening the distance of the battery 1000 in the first direction Z.

[0070] Referring to Figures 2 and 3 , in some embodiments of the present application, the battery 1000 further includes a first protective film 15 , which covers at least a portion of the mounting bracket 2 and the battery cell 1. The first protective film 15 secures the mounting bracket 2 and the battery cell 1 relative to each other. Since the first and second limiting portions 131 and 132 can limit the mounting bracket 2 in the second direction X and the third direction Y, in this embodiment, the first protective film 15 also limits the mounting bracket 2 in the first direction Z, thereby fully securing the mounting bracket 2 to the battery cell 1. In one embodiment of the present application, the first protective film 15 covers the fixed connection portion 13 and the mounting bracket 2.

[0071] Referring to Figures 2 and 3 , in some embodiments of the present application, the battery 1000 further includes a second protective film 16 , which at least partially covers the second end 11B of the battery cell 1 . The second protective film 16 protects the second end 11B of the battery cell 1 , and further covers the side surfaces of the battery cell body 11 , thereby securely securing the second protective film 16 to the battery cell body 11 .

[0072] Referring to Figures 1 and 2, the battery 1000 further includes a protective cover 17, which is sleeved on the outer surface of the battery cell body 11; the protective cover 17 is sleeved on at least a portion of the mounting bracket 2. The protective cover 17 is provided to protect the outer surface of the battery cell body 11 and a portion of the structure of the mounting bracket 2. In addition to the first protective film 15 and the second protective film 16, the protective cover 17 also covers the first protective film 15 and the second protective film 16 to prevent the first protective film 15 and the second protective film 16 from falling off the battery cell 1. The protective cover 17 is sleeved on the battery cell body 11 in a heat shrinkable manner to improve the reliability of the fixation between the protective cover 17 and the battery cell body 11 and the portion of the structure of the mounting bracket 2.

[0073] In some embodiments of the present application, a label 18 is provided on the outer surface of the protective cover 17 .

[0074] Referring to Figures 2 and 7 , in some embodiments of the present application, the first protective plate 3 further includes a circuit board 33 and at least one electrical component 34. The circuit board 33 constitutes at least a portion of the output portion 31, and the electrical component 34 is disposed on the circuit board 33. In this embodiment, the main portion of the first protective plate 3 is the circuit board 33, which is bent to form the output portion 31 and a portion of the first sub-board 32. The output portion 31 is formed by copper terminals or surface-mount terminals disposed on the circuit board 33, and the first sub-board 32 is formed by electrical components 34 disposed on the circuit board 33. It will be understood that because the circuit board 33 is bendable, it is a flexible circuit board.

[0075] The battery 1000 of this embodiment uses a square soft-pack battery cell. By arranging a mounting bracket 2 and a first protective plate 3 on the square soft-pack battery cell to form the battery 1000, the battery 1000 has a simple structure and low cost. At the same time, it can also ensure that the square soft-pack battery cell is not damaged when the battery 1000 is replaced.

[0076] Among them, based on the fact that the battery cell used in battery 1000 is a square soft-pack battery cell, since the square soft-pack battery cell is formed by an aluminum-plastic film wrapped on the outside of the core package, the positive electrode ear and the negative electrode ear extend from one end or both ends of the aluminum-plastic film, and the aluminum-plastic film extends out of the side of the positive electrode ear and the negative electrode ear to form a top seal, that is, the first limiting portion 131 and the second limiting portion 132 both extend from the battery cell body 11, that is, the first limiting portion 131 and the second limiting portion 132 are the top seal of the square soft-pack battery cell.

[0077] Example 2

[0078] Referring to Figures 17 and 18 , in some embodiments of the present application, the output structure includes a first connector 3A. The first connector 3A is mounted on the mounting bracket 2 and connected to the tab 12. The first connector 3A is configured to connect to a second connector on the power-consuming device. In other words, the battery 1000 can supply power to the power-consuming device via the first connector 3A.

[0079] Among them, the battery 1000 includes a battery cell 1, the battery cell 1 includes a battery cell body 11 and a tab 12, the battery cell body 11 includes a first end 11A, and the tab 12 extends from the first end 11A of the battery cell body 11 along a first direction Z; wherein, there are two tabs 12, and the two tabs 12 are respectively a positive tab and a negative tab.

[0080] The battery 1000 also includes a mounting bracket 2, which is fixedly disposed at the first end 11A of the battery cell body 11; wherein the mounting bracket 2 and the tab 12 are also located at the first end 11A of the battery cell body 11. In one embodiment, the tab 12 may be located inside the mounting bracket 2; in another embodiment, the tab 12 may be located on other components of the battery 1000.

[0081] In the technical solution of this embodiment, a mounting bracket 2 is provided to be fixedly connected to the battery cell body 11, and then the first connector 3A on the mounting bracket 2 is plugged into and matched with the second connector on the electrical equipment, so as to supply power to the electrical equipment; wherein, the structural form in which the first connector 3A is installed on the mounting bracket 2 and matched with the second connector of the electrical equipment not only facilitates the disassembly and assembly of the battery 1000 on the electrical equipment, but also the battery cell 1 is not directly fixed to the electrical equipment, thereby avoiding damage to the battery cell 1 during replacement and disassembly.

[0082] In some embodiments of the present application, one of the first connector 3A and the second connector is a male connector, and the other is a female connector; the male and female connectors cooperate to secure the battery 1000 to the electrical device and enable the battery 1000 to supply power to the electrical device. In one embodiment of the present application, the first connector 3A is a male connector, and the second connector is a female connector.

[0083] It is understandable that, since the mounting bracket 2 has a certain structural strength, when the first connector 3A is plugged into and mated with the second connector on the electrical device, the battery cell body 11 fixed to the mounting bracket 2 is also limited.

[0084] In some embodiments of the present application, battery 1000 further includes a second protective plate 4A and a second connector 5A. The second protective plate 4A is mounted on mounting bracket 2, and the first connector 3A is correspondingly fixed to the second protective plate 4A. The second connector 5A connects the tab 12 to the second protective plate 4A. The second protective plate 4A provides overcharge protection, over-discharge protection, overcurrent protection, and short-circuit protection for the battery cell 1. The second connector 5A electrically connects the tab 12 to the second protective plate 4A. Because the tab 12 includes a positive tab and a negative tab, two second connectors 5A are also provided in this embodiment.

[0085] Furthermore, the position of the second protective plate 4A and the first connector 3A mounted thereon on the mounting bracket 2 is not restricted; the only requirement is that the first connector 3A is exposed on the outer surface of the battery 1000 and can be connected to the second connector on the electrical device. In one embodiment of the present application, the second protective plate 4A is disposed on one side of the mounting bracket 2 in the third direction Y.

[0086] In some embodiments of the present application, the battery 1000 further includes two first stoppers 6A mounted on the mounting bracket 2. The two first stoppers 6A are spaced apart in the second direction X and located at opposite ends of the second protective plate 4A. The two first stoppers 6A are configured to limit the position of the second protective plate 4A. Since the two first stoppers 6A are spaced apart, there is a certain amount of space between the two first stoppers 6A for the installation of the second protective plate 4A. The second protective plate 4A is positioned between the two first stoppers 6A, and the second protective plate 4A and the first connector 3A mounted on the second protective plate 4A are fixed relative to the mounting bracket 2.

[0087] In some embodiments of the present application, each first retaining member 6A includes a main portion 61 and a protrusion 62. The main portion 61 extends along the third direction Y and is fixedly connected to the mounting bracket 2. The protrusion 62 is fixed to the end of the main portion 61 facing away from the mounting bracket 2. The protrusion 62 protrudes beyond the main portion 61 in the second direction X and overlaps the second protective plate 4A. In other words, in this embodiment, when the second protective plate 4A is restrained between the two first retaining members 6A, the protrusion 62 and the mounting bracket 2 are respectively located on opposite sides of the second protective plate 4A in the third direction Y, thereby restraining and fixing the second protective plate 4A in the third direction Y. The two protrusions 62 are respectively located on opposite sides of the second protective plate 4A in the second direction X, thereby restraining and protecting the second protective plate 4A in the second direction X.

[0088] It can be understood that the installation of the second protective plate 4A is that the second protective plate 4A moves in the direction close to the mounting bracket 2 in the third direction Y, and the second protective plate 4A needs to pass between the two protrusions 62 until it enters between the two main bodies 61. Since the relative distance between the two protrusions 62 in the second direction X is smaller than the relative distance between the two main bodies 61 in the second direction X, at least one of the first limit member 6A and the second protective plate 4A can undergo elastic deformation, thereby ensuring that the second protective plate 4A can be smoothly installed between the two first limit members 6A.

[0089] Likewise, at least portions of the surfaces of the two protrusions 62 that are opposite to each other in the second direction X are inclined surfaces, thereby facilitating the installation of the second protective plate 4A.

[0090] Please refer to Figures 19 and 20. In some embodiments of the present application, the battery 1000 further includes a second limiter 7A, which is fixed to the mounting bracket 2. The second limiter 7A protrudes from the mounting bracket 2 in the third direction Y and is spaced apart from the battery cell body 11. In the first direction Z, the second protective plate 4A is disposed between the second limiter 7A and the battery cell body 11. In this embodiment, the second limiter 7A and the battery cell body 11 can block the movement of the second protective plate 4A in the first direction Z, that is, limit the movement of the second protective plate 4A in the first direction Z. The number of second limiters 7A is not limited and can be one or more. In one embodiment of the present application, three second limiters 7A are provided, and the three second limiters 7A are spaced apart in the second direction X.

[0091] Among them, the two main parts 61 can limit the second protective plate 4A in the second direction X, the protrusion 62 and the mounting bracket 2 can limit the second protective plate 4A in the third direction Y, and the second limiting member 7A and the battery cell body 11 can limit the second protective plate 4A in the first direction Z, thereby achieving full-range limiting and fixing of the second protective plate 4A, preventing the second protective plate 4A and the first connector 3A fixed on the second protective plate 4A from falling off from the mounting bracket 2.

[0092] However, since the mounting bracket 2 and the cell body 11 are not integrally formed but are separable from each other, the second retaining member 7A mounted on the cell body 11 and the mounting bracket 2 may limit the second protective plate 4A, which may result in a problem of insecure fixation of the second protective plate 4A. Therefore, in some embodiments of the present application, the battery 1000 further includes a third retaining member 8A, which is fixed to the mounting bracket 2 and protrudes from the mounting bracket 2 in the third direction Y. The third retaining member 8A is disposed on a side of the second retaining member 7A proximal to the cell body 11 in the first direction Z and spaced apart from the second retaining member 7A. The second retaining member 7A and the third retaining member 8A cooperate to limit the second protective plate 4A. In this embodiment, the second retaining member 7A and the third retaining member 8A are both fixed to the mounting bracket 2. When the second protective plate 4A is mounted between the second retaining member 7A and the third retaining member 8A, the second protective plate 4A is not easily movable in the first direction Z.

[0093] It can be understood that since the first limit member 6A, the second limit member 7A and the third limit member 8A limit and fix the second protective plate 4A, and the first connector 3A is installed on the second protective plate 4A, it is necessary to avoid interference between the first limit member 6A, the second limit member 7A and the third limit member 8A and the position of the first connector 3A. Similarly, the first limit member 6A, the second limit member 7A and the third limit member 8A also need to avoid interference with the fit of the first connector 3A and the second connector; in one embodiment of the present application, the first connector 3A is arranged on the side of the second protective plate 4A away from the mounting bracket 2 in the third direction Y; on the basis of this embodiment, in order to avoid interference between the second limit member 7A and the fit of the first connector 3A and the second connector, at least a portion of the first connector 3A protrudes from the second limit member 7A in the third direction Y, so that the first connector 3A and the second connector can fit normally.

[0094] In addition, since the first connector 3A is arranged on the side of the second protective plate 4A that is away from the mounting bracket 2 in the third direction Y, such an arrangement can effectively reduce the length of the battery 1000 in the first direction Z; in one embodiment of the present application, the positive projection of the first connector 3A in the third direction Y falls completely on the second protective plate 4A.

[0095] Referring to FIG. 21 , in some embodiments of the present application, the mounting bracket 2 includes a fourth frame 21A and a fifth frame 22A spaced apart in a third direction Y. A third confining space 9A is formed between the fourth frame 21A and the fifth frame 22A. The third confining space 9A is configured to accommodate the tab 12. A second protective plate 4A is disposed on a side of the fourth frame 21A facing away from the fifth frame 22A in the third direction Y. The tab 12 is located within the third confining space 9A, and the mounting bracket 2 can provide a certain degree of protection for the tab 12 in the third direction Y.

[0096] Since the fourth frame 21A separates the electrode tab 12 and the second protective plate 4A in the third direction Y, and the electrode tab 12 and the second protective plate 4A are connected by the second connecting member 5A, in order to ensure the connection between the electrode tab 12 and the second protective plate 4A, in one embodiment, the second connecting member 5A can pass through the fourth frame 21A in the third direction Y, thereby realizing the connection between the second protective plate 4A and the electrode tab 12; in another embodiment, the second connecting member 5A can bypass the fourth frame 21A to realize the connection between the second protective plate 4A and the electrode tab 12.

[0097] In one embodiment of the present application, the second connector 5A includes a third sub-connecting portion 51A, a fourth sub-connecting portion 52A, and a curved portion 53. The third sub-connecting portion 51A extends along the first direction Z and connects to the tab 12. The fourth sub-connecting portion 52A extends along the first direction Z and connects to the second protective plate 4A. The curved portion 53 is disposed on the side of the fourth frame 21A facing away from the battery cell 1 in the first direction Z. The two ends of the curved portion 53 are respectively connected to the third sub-connecting portion 51A and the fourth sub-connecting portion 52A. In other words, in this embodiment, the second connector 5A is curved, with one end of the second connector 5A connected to the tab 12 and the other end connected to the second protective plate 4A. Specifically, the third sub-connecting portion 51A connects to the tab 12, and the fourth sub-connecting portion 52A connects to the second protective plate 4A. When the second protective plate 4A is mounted on the mounting bracket 2, the second connector 5A can restrict movement of the mounting bracket 2 in the first direction Z to a certain extent, preventing the mounting bracket 2 from separating from the battery cell body 11 in the first direction Z.

[0098] It should be noted that the second connector 5A is configured in this way, which will cause at least part of the second connector 5A to be exposed to the external environment. In order to avoid short circuit problems in the battery 1000, an insulating layer is also provided on the part of the second connector 5A that is not connected to the tab 12 and the second protective plate 4A.

[0099] Referring to Figures 20 and 21 , in some embodiments of the present application, the mounting bracket 2 further includes a sixth frame 23A, which connects the fourth frame 21A and the fifth frame 22A. The tab 12 is correspondingly disposed between the cell body 11 and the sixth frame 23A. The sixth frame 23A and the cell body 11 are respectively located on either side of the tab 12 in the first direction Z, thereby protecting the tab 12. In other words, the sixth frame 23A not only connects the fourth frame 21A and the fifth frame 22A, but also protects the tab 12.

[0100] Because the installation of the sixth frame 23A interferes with the installation path of the second connector 5A, in one embodiment of the present application, at least a portion of the sixth frame 23A is hollowed out. At least a portion of the curved portion 53 extends from the hollowed-out portion of the sixth frame 23A to the third confining space 9A and connects to the third sub-connecting portion 51A. The hollowing of the sixth frame 23A is not limited to any specific form. The hollowing structure can be formed by concave edges of the sixth frame 23A toward the center, or by a hole extending through the sixth frame 23A. In one embodiment of the present application, an opening 20A extending along the first direction Z is formed through the sixth frame 23A. The opening 20A communicates with the third confining space 9A, allowing the second connector 5A to extend from the opening 20A into the third confining space 9A, thereby connecting the tab 12 to the second protective plate 4A. Since there are two tabs 12, two openings 20A are defined in the sixth frame 23A.

[0101] In addition, the thickness of the portion of the second connecting member 5A located at the opening 20A in the first direction Z is less than the depth of the opening 20A in the first direction Z, so that the peripheral side wall of the opening 20A is formed on the sixth frame 23A to protect the portion of the second connecting member 5A located at the opening 20A.

[0102] Since there are two second connecting members 5A, one of the second connecting members 5A is made of aluminum and the other second connecting member 5A is made of nickel, please refer to Figure 21. In some embodiments of the present application, the battery 1000 also includes a welding portion 10A, which is curved; wherein at least a portion of the welding portion 10A is arranged between the fourth sub-connecting portion 52A and the second protective plate 4A, and connects the fourth sub-connecting portion 52A and the second protective plate 4A; another portion of the welding portion 10A is arranged on the side of the fourth sub-connecting portion 52A away from the second protective plate 4A in the third direction Y, and is connected to the fourth sub-connecting portion 52A. In this embodiment, two welding parts 10A are provided, and the welding parts 10A are nickel sheets. When the second connecting member 5A made of aluminum is laser welded with the nickel sheet, poor welding may occur. Therefore, the welding parts 10A are bent and cover the opposite sides of the fourth sub-connecting part 52A on the second connecting member 5A, thereby improving the welding yield and ensuring that the second connecting member 5A and the second protective plate 4A are firmly welded.

[0103] Referring to Figures 21 and 22 , the battery 1000 further includes a third limiting portion 13 extending from the first end of the cell body 11 and located within the third limiting space 9A. The tab 12 extends from a side of the third limiting portion 13 facing away from the cell body 11 in the first direction Z. Because the third limiting portion 13 is disposed on the cell body 11, the fourth frame 21A and the fifth frame 22A are located on either side of the third limiting portion 13 in the third direction Y. This means that the third limiting portion 13 restricts movement of the mounting bracket 2 in the third direction Y.

[0104] Referring to Figure 23 , the battery cell 1 further includes two fourth limiting portions 14A, one located on either side of the battery cell body 11 in the second direction X. Both fourth limiting portions 14A extend from the battery cell body 11 and along the first direction Z. A fourth limiting space 15A is formed between the two fourth limiting portions 14A. The fourth limiting space 15A is configured to accommodate the fourth frame 21A. The fourth limiting portions 14A limit movement of the fourth frame 21A in the second direction X, thereby limiting movement of the mounting bracket 2 in the second direction X.

[0105] Among them, the third limiting portion 13 and the two fourth limiting portions 14A can be separated or integrated; in one embodiment of the present application, the third limiting portion 13 and the fourth limiting portion 14A are integrated, that is, the third limiting portion 13 extends along the second direction X, thereby connecting with the two fourth limiting portions 14A.

[0106] Please refer to Figure 17 again. The battery 1000 also includes at least one protrusion 4, which extends from the mounting bracket 2; the electrical device includes a clamping portion, and the protrusion 4 is clamped and fixed to the clamping portion of the electrical device. That is, the mounting bracket 2 cooperates with the clamping portion on the electrical device through the protrusion 4 to further fix the battery 1000 to the electrical device, and the protrusion can be set at any position of the mounting bracket 2. In one embodiment of the present application, there are two protrusions 4, and they are located on opposite sides of the mounting bracket 2 in the second direction X, so as to ensure that the battery 1000 is firmly fixed in the electrical device. It should be added that the shape of the protrusion 4 is not limited, and can be a polygonal structure, a circular structure, a columnar structure or an irregular structure.

[0107] In some embodiments of the present application, the battery cell body 11 includes a second end 11B opposite the first end 11A in the first direction Z. The battery 1000 also includes a second protective film 16 , at least partially covering the second end 11B of the battery cell body 11 in the first direction Z. The second protective film 16 protects the second end 11B of the battery cell 1 in the first direction Z. The second protective film 16 also covers the circumferential side surfaces of the battery cell body 11 , thereby securely securing the second protective film 16 to the battery cell body 11 .

[0108] Referring again to Figure 17 , battery 1000 further includes a protective sleeve 17, which is disposed over the outer surface of cell body 11. Protective sleeve 17 protects cell body 11. Protective sleeve 17 also partially covers second protective film 16, further preventing it from falling off cell 1.

[0109] A label 18 is provided on the outer surface of the protective cover 17 .

[0110] In addition, the battery cell 1 used in the battery 1000 of this embodiment is a square soft-pack battery cell 1. By providing a mounting bracket 2 and a first connector 3A on the square soft-pack battery cell 1 to form the battery 1000, damage to the square soft-pack battery cell 1 can be avoided when the battery 1000 is replaced.

[0111] Among them, on the basis that the battery cell 1 used in the battery 1000 is a square soft-pack battery cell 1, since the square soft-pack battery cell 1 is formed by an aluminum-plastic film wrapped on the outside of the core package, the positive electrode ear and the negative electrode ear extend from one end or both ends of the aluminum-plastic film, and the aluminum-plastic film extends out of the side of the positive electrode ear and the negative electrode ear to form a top seal, that is, the third limiting portion 13 and the fourth limiting portion 14A both extend from the battery cell body 11, that is, the third limiting portion 13 and the fourth limiting portion 14A are the top seal of the square soft-pack battery cell 1.

[0112] The present application also proposes an electrical device, which includes an electrical device and a battery 1000, wherein the battery 1000 is installed in the electrical device; wherein at least one of the output structure and the mounting bracket 2 is configured to be fixed to the electrical device.
