[0039] The housing 100 defines a receiving cavity 110 with an opening. The housing 100 includes a first outer shell 120 and a second outer shell 130 connected to each other. The connection method between the first outer shell 120 and the second outer shell 130 includes any one of snap-fit, adhesive, bolt connection, threaded connection or interference fit connection, which can be specifically set according to the actual situation.

[0040] It is understandable that by detachably connecting the first housing 120 and the second housing 130, the stability and overall strength of the housing 100 are ensured, while the installation or disassembly efficiency of the housing 100 is improved, the battery assembly efficiency is improved, and thus the battery production efficiency is improved.

[0041] The battery cell 200 is housed in the receiving cavity 110, so that the housing 100 provides protection for the battery cell 200 and ensures the safety of the battery cell 200 in the receiving cavity 110.

[0042] The battery cell 200 has a positive terminal 210 and a negative terminal 220. The positive terminal 210 of the battery cell 200 faces the opening, and the negative terminal 220 of the battery cell 200 faces away from the opening.

[0043] In this embodiment, the axis of the battery cell 200 is parallel to or coincides with the axis of the housing 100.

[0044] The control board 300 is housed in the receiving cavity 110 and is disposed on the side of the battery cell 200 facing the opening along the axial direction of the battery cell 200. The control board 300 is connected to the housing 100 so that the housing 100 provides a limiting and fixing function for the control board 300, thereby ensuring the stability of the connection between the control board 300 and the housing 100.

[0045] In this configuration, one end of the first conductive element 400 is electrically connected to the positive terminal 210, and the other end of the first conductive element 400 is electrically connected to the control board 300, thereby electrically connecting the positive terminal 210 and the control board 300 through the first conductive element 400. Similarly, one end of the second conductive element 500 is electrically connected to the negative terminal 220, and the other end of the second conductive element 500 is electrically connected to the control board 300, thereby electrically connecting the negative terminal 220 and the control board 300 through the second conductive element 500. This, in turn, electrically connects the battery cell 200 and the control board 300 through the first conductive element 400 and the second conductive element 500.

[0046] It should be noted that the first conductive element 400 and the second conductive element 500 can be one of a wire, a nickel strip, or a nickel sheet, respectively.

[0047] In addition, in some embodiments, the control board 300 has a connection pad corresponding to the positive terminal 210 and the negative terminal 220 on one side. The connection pad is provided with nickel plate terminals, so that the first conductive element 400 and the second conductive element 500 can be quickly spot welded to the nickel plate terminals respectively, thereby improving the stability and efficiency of the electrical connection.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the first housing 120 is provided with a first connecting portion 121 on the side facing the second housing 130, and the second housing 130 is provided with a second connecting portion 131 on the side facing the first housing 120, and the first connecting portion 121 and the second connecting portion 131 are connected.

[0049] In some embodiments, the number of first connecting portions 121 and second connecting portions 131 are both multiple and equal. Multiple first connecting portions 121 are spaced apart on the side of the first housing 120 facing the second housing 130, and multiple second connecting portions 131 are spaced apart on the side of the second housing 130 facing the first housing 120. Each first connecting portion 121 is connected to one second connecting portion 131. By providing multiple first connecting portions 121 and multiple second connecting portions 131, the stability of the connection between the first housing 120 and the second housing 130 is improved.

[0050] like Figure 2 As shown, in some embodiments, the first connecting portion 121 includes a groove 1211 and a protrusion 1212 disposed in the first housing 120, the protrusion 1212 being received in the groove 1211, and the sidewall of the protrusion 1212 being spaced apart from the groove wall of the groove 1211.

[0051] It should be noted that the second connecting part 131 includes a connecting buckle 1311, and the buckle 1311 is provided with a mounting hole 1312, which extends through the buckle 1311 along the thickness direction of the buckle 1311.

[0052] In this embodiment, the buckle 1311 is received in the groove 1211, and the protrusion 1212 passes through the mounting hole 1312 to connect the first connecting part 121 and the second connecting part 131, thereby connecting the first outer shell 120 and the second outer shell 130.

[0053] like Figure 5 and Figure 6As shown, in some embodiments of this application, the first housing 120 is provided with at least one first guide post 122, the first guide post 122 is provided with a first guide hole 1221 on the side facing the second housing 130, the second housing 130 is provided with at least one first connecting rod 132, the first connecting rod 132 is at least partially engaged in the first guide hole 1221; and / or, the second housing 130 is provided with at least one second guide post 133, the second guide post 133 is provided with a second guide hole 1331 on the side facing the first housing 120, the first housing 120 is provided with at least one second connecting rod 123, the second connecting rod 123 is at least partially engaged in the second guide hole 1331.

[0054] It is understandable that the number of the first guide post 122, the first connecting rod 132, the second guide post 133, and the second connecting rod 123 can be any number of one, two, or more, and can be specifically set according to the actual situation.

[0055] It should be noted that the number of first guide posts 122 is equal to the number of first connecting rods 132, and the number of second guide posts 133 is equal to the number of second connecting rods 123.

[0056] In some embodiments, the first housing 120 is provided with at least one first guide post 122, and the first guide post 122 is provided with a first guide hole 1221 on the side facing the second housing 130. The second housing 130 is provided with at least one first connecting rod 132, and the first connecting rod 132 is at least partially engaged in the first guide hole 1221 to form a limiting connection structure. This structure provides guidance and limiting for the connection between the first housing 120 and the second housing 130 through the first guide post 122 and the first connecting rod 132, thereby ensuring the accuracy and efficiency of the connection between the first housing 120 and the second housing 130.

[0057] In other embodiments, the first housing 120 is provided with at least one first guide post 122, and the first guide post 122 is provided with a first guide hole 1221 on the side facing the second housing 130. The second housing 130 is provided with at least one first connecting rod 132, and the first connecting rod 132 is at least partially engaged in the first guide hole 1221 to form a limiting connection structure. This structure provides guidance and limiting for the connection between the first housing 120 and the second housing 130 through the second guide post 133 and the second connecting rod 123, thereby ensuring the accuracy and efficiency of the connection between the first housing 120 and the second housing 130.

[0058] like Figure 4 and Figure 5As shown, in this embodiment, the first housing 120 is provided with at least one first guide post 122, and the first guide post 122 has a first guide hole 1221 on the side facing the second housing 130. The second housing 130 is provided with at least one first connecting rod 132, and the first connecting rod 132 is at least partially engaged in the first guide hole 1221. The second housing 130 is provided with at least one second guide post 133, and the second guide post 133 has a second guide hole 1331 on the side facing the first housing 120. The first housing 120 is provided with at least one second connecting rod 123, and the second connecting rod 123 is at least partially engaged in the second guide hole 1331. By providing a first guide post 122 and a second connecting rod 123 on the first housing 120, and a second guide post 133 and a first connecting rod 132 on the second housing 130, a misaligned guiding structure is formed between the first housing 120 and the second housing 130 through the first guide post 122, the first connecting rod 132, the second guide post 133 and the second connecting rod 123. This not only improves the installation efficiency between the first housing 120 and the second housing 130, but also effectively avoids the situation where the first housing 120 and the second housing 130 are installed backwards, further ensuring the accuracy of the installation between the first housing 120 and the second housing 130.

[0059] like Figures 3 to 6 As shown, in some embodiments of this application, the inner wall of the housing 100 is provided with a first limiting groove 140, and the edge portion of the control plate 300 is engaged in the first limiting groove 140.

[0060] The first limiting groove 140 can be one, two or more, depending on the specific requirements.

[0061] For example, if there are multiple first limiting grooves 140, the multiple first limiting grooves 140 are spaced apart on the inner wall of the housing 100.

[0062] It should be noted that in this embodiment, there is only one first limiting groove 140, which is an annular groove. Two spaced-apart first protruding rings are provided on the inner wall of the housing 100 to form the first limiting groove 140 through the gap between the two first protruding rings. The groove wall of the first limiting groove 140 forms a limiting effect on the control plate 300 to ensure the stability of the control plate 300 in the receiving cavity 110, and at the same time ensure the stability of the connection between the control plate 300 and the housing 100.

[0063] like Figures 3 to 6As shown, in some embodiments of this application, the battery further includes a negative electrode disk 600 and a positive electrode cap 800. The negative electrode disk 600 is disposed on the side of the cell 200 away from the control board 300, and one end of the second conductive member 500 connected to the negative terminal 220 of the cell 200 is electrically connected to the negative electrode disk 600. The positive electrode cap 800 is disposed on the side of the control board 300 away from the cell 200, and the positive electrode cap 800 is electrically connected to the positive terminal 210 of the cell 200 through the control board 300.

[0064] Specifically, one end of the second conductive element 500 that is electrically connected to the negative terminal 220 is disposed between the negative electrode disk 600 and the battery cell 200, and the second conductive element 500 and the negative electrode disk 600 are connected by spot welding to ensure the stability of the connection between the second conductive element 500 and the negative electrode disk 600, while improving the connection efficiency between the second conductive element 500 and the negative electrode disk 600.

[0065] It should be noted that the negative electrode disk 600 is a negative electrode conductive metal disc.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the inner wall of the housing 100 is provided with a second limiting groove 150, the edge of the negative electrode disk 600 is engaged in the second limiting groove 150, and the groove wall of the second limiting groove 150 abuts against the edge of the negative electrode disk 600, so as to provide a limiting effect on the negative electrode disk 600 through the groove wall of the second limiting groove 150, so as to ensure the stability of the connection between the negative electrode disk 600 and the housing 100, and at the same time, the negative electrode disk 600 provides a supporting effect on the battery cell 200, so as to ensure the stability of the battery cell 200 in the receiving cavity 110.

[0067] It should be noted that, in this embodiment, the inner wall of the housing 100 is provided with spaced second protruding rings, which are disposed on the side of the housing 100 near the negative end 220, so as to define the second limiting groove 150 between the two spaced second protruding rings.

[0068] like Figures 2 to 4 As shown, in some embodiments of this application, along the axial direction of the housing 100, the housing 100 has a top plate 160 on the side near the control plate 300, and the top plate 160 is provided with at least one through hole 161, which communicates with the receiving cavity 110.

[0069] It is understandable that the number of through holes 161 can be one, two or more, depending on the specific circumstances.

[0070] In this embodiment, there are two through holes 161, which are spaced apart to connect the receiving cavity 110 with the external space of the housing 100. This allows the gas generated during the use of the battery cell 200 to be discharged through the through holes 161, thereby achieving the purpose of depressurizing the battery cell 200 and ensuring the safety of the battery during use.

[0071] like Figure 2 As shown, in some embodiments of this application, the control board 300 has a charging port 310 on the side opposite to the battery cell 200. The charging port 310 is exposed in the opening so that the charging port 310 can be connected to an external power source through a data cable, thereby charging the battery through the external power source and enabling the battery to be reused.

[0072] In this embodiment, the charging port 310 is a Type-C interface.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments of this application, an insulating member 700 is provided between the battery cell 200 and the control board 300. The insulating member 700 abuts between the battery cell 200 and the control board 300 to form an insulating barrier between the control board 300 and the positive terminal 210, so as to prevent the control board 300 from directly contacting the positive terminal 210.

[0074] In some embodiments, the insulating element 700 may be insulating cotton, insulating adhesive, or insulating board, which may be specifically set according to the actual situation.

[0075] In this embodiment, the insulating component 700 is insulating cotton. This insulating cotton not only forms an insulating barrier between the battery cell 200 and the control board 300, but also plays a role in buffering, supporting and shock absorption between the control board 300 and the battery cell 200, so as to ensure the stability and safety of the control board 300 and the battery cell 200 in the receiving cavity 110.

[0076] like Figure 3 and Figure 5 As shown, in some embodiments of this application, the inner wall of the housing 100 is provided with a plurality of first reinforcing ribs 170 extending along the axial direction. The plurality of first reinforcing ribs 170 are arranged circumferentially along the inner wall of the housing 100 to improve the overall strength of the housing 100 and ensure the stability of the housing 100.

[0077] In addition, the inner wall of the housing 100 is provided with a plurality of second reinforcing ribs 180 along a direction perpendicular to the axis. The plurality of second reinforcing ribs 180 are spaced apart and intersect with the first reinforcing ribs 170 to further enhance the strength and stability of the housing 100.

[0078] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the control board 300 is provided with a light guide post 320 on the side opposite to the battery cell 200. The light guide post 320 passes through the top plate 160 of the housing 100 so that the light emitted by the light guide post 320 can display the charging or usage status of the battery.

[0079] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0080] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0081] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
