[0040] In one embodiment, the first battery module 210 and the second battery module 220 may be multiple groups, and the first battery modules 210 and the second battery modules 220 in different groups may be arranged sideways.

[0041] Figure 2 This is a schematic diagram of the structure of the first battery module, the second battery module and the CCS assembly in an expanded state provided by an exemplary embodiment of the present application. Figure 1 and Figure 2As shown, the battery pack 200 may also include a CCS assembly 100 (wiring harness integrated component), the CCS assembly 100 connects the first battery module 210 and the second battery module 220. On the one hand, the CCS assembly 100 can serve as a rotating shaft of the first battery module 210 and the second battery module 220 to assist the first battery module 210 and the second battery module 220 to flip relative to each other to achieve a side-lying state ( Figure 1 shown state) and expanded state ( Figure 2 On the other hand, the CCS component 100 can be used as a collection line 230 ( Figure 4 The assembly carrier (shown in the figure) assists in the temperature collection operation, cancels the setting of the conventional FPC, reduces the space occupied by the collection line 230, and improves the space utilization inside the battery pack 200.

[0042] Specifically, Figure 3 A schematic structural diagram of a first battery module, a second battery module and a CCS assembly in a side-lying state provided in an exemplary embodiment of the present application. Figure 4 for Figure 3 A magnified schematic diagram of center A. Figure 5 A schematic diagram of the structure of a first battery module, a second battery module and a battery sheet in a side-lying state provided in an exemplary embodiment of the present application. Figure 6 for Figure 5 A magnified schematic diagram of point B in the middle. Figure 7 This is a schematic diagram of the structure of the CCS component, the acquisition line and the bar provided by an exemplary embodiment of the present application. Figures 3 to 7 As shown, the battery pack 200 may include multiple bars 240 and collection lines 230, wherein some of the bars 240 are connected to the poles 270 of the battery cells in the first battery module 210, and another part of the bars 240 are connected to the poles 270 of the battery cells in the second battery module 220, and the collection lines 230 are connected to multiple bars 240. In actual applications, the bars 240 can transmit current and voltage, and the collection lines 230 can collect parameters such as temperature and voltage when the bars 240 are working, providing parameter basis for the battery management system to execute corresponding charging and discharging strategies.

[0043] Specifically, Figure 4 and Figure 7 As shown, the CCS assembly 100 may include a mounting body 110 and a rotating body 120, the rotating body 120 is rotatably connected to the mounting body 110, the rotating body 120 is provided with a wiring channel 121 and a plurality of bearing parts 122, the collection line 230 is passed through the wiring channel 121, and the plurality of bearing parts 122 can be used to carry a plurality of bars 240.

[0044] It should be understood that, in practical applications, the rotating body 120 rotates relative to the mounting body 110, so that the first battery module 210 and the second battery module 220 can be relatively flipped to achieve a side-lying state ( Figure 1 shown state) and expanded state ( Figure 2 By switching between the states shown in the figure, the first battery module 210 and the second battery module 220 can be assembled in a side-lying manner to reduce the number of assembly steps required for the first battery module 210 and the second battery module 220, thereby improving assembly efficiency. In addition, by passing the acquisition line 230 through the wiring channel 121 and canceling the setting of the conventional FPC, the amount of space occupied by the acquisition line 230 during routing can be reduced, thereby improving the space utilization inside the battery pack 200.

[0045] Figure 8 A schematic structural diagram of a first isolation plate and a first connecting pipe provided in an exemplary embodiment of the present application. Fig. 9 Schematic diagram of the structure of the second isolation plate and the second connecting pipe provided by an exemplary embodiment of the present application. Figures 7 to 9 As shown, the rotating body 120 may include a first isolation plate 123 and a second isolation plate 124, the first isolation plate 123 is provided with at least one first connecting tube 125, the second isolation plate 124 is provided with at least one second connecting tube 126, the first connecting tube 125 and the second connecting tube 126 are both rotatably connected to the mounting body 110, and after the inner cavity of the first connecting tube 125 is connected with the inner cavity of the second connecting tube 126, a routing channel 121 can be formed, that is, the acquisition line 230 will pass through the inner cavity of the first connecting tube 125 and the second connecting tube 126 during the routing process.

[0046] It should be understood that the first connecting tube 125 and the second connecting tube 126 can protect the collection line 230 , and the first isolation plate 123 and the second isolation plate 124 can be used to load the bar sheet 240 and serve as a carrier of the bar sheet 240 .

[0047] In one embodiment, the bar pieces 240 loaded on the first isolation plate 123 are used to connect the poles 270 of the battery cells of the first battery module 210, and the bar pieces 240 loaded on the second isolation plate 124 are used to connect the poles 270 of the battery cells of the second battery module 220. In this way, the bar pieces 240 connecting different battery modules are separated by the first isolation plate 123 and the second isolation plate 124, which can avoid the situation where the bar pieces 240 of different battery modules are attached to each other and cause a short circuit.

[0048] In one embodiment, the number of the first connecting tubes 125 may be one, two, three, etc.; the number of the second connecting tubes 126 may be one, two, three, etc.

[0049] like Figure 8 and Fig. 9As shown, the bearing portion 122 includes a groove 1221, and the tab 240 can be accommodated in the groove 1221. The groove 1221 can limit the tab 240 to ensure that the tab 240 remains in the initial installation position, thereby ensuring that the tab 240 can be connected to the pole 270 of the battery cell for a long time.

[0050] like Figure 7 As shown, the inner wall of the groove 1221 is provided with a through hole 260. On the one hand, the tab 240 can be connected to the pole 270 of the battery cell through the through hole 260; on the other hand, the through hole 260 is provided on the inner wall of the groove 1221, which can reduce the overall weight of the rotating body 120 and reduce the production cost.

[0051] Fig.10 This is a schematic diagram of the structure of the installation body provided by an exemplary embodiment of the present application. Figures 7 to 10 As shown, the mounting body 110 is provided with an arc-shaped slot 111 , and the first connecting tube 125 and the second connecting tube 126 are coaxially arranged along the length direction of the slot 111 . The first connecting tube 125 and the second connecting tube 126 are rotatably clamped in the slot 111 around the same axis.

[0052] It should be understood that, on the one hand, the arc-shaped slot 111 is adapted to the shape of the first connecting tube 125 and the second connecting tube 126, and the arc-shaped slot 111 can assist the first connecting tube 125 and the second connecting tube 126 to rotate more smoothly, thereby facilitating the flipping of the first battery module 210 and the second battery module 220; on the other hand, the coaxially arranged first connecting tube 125 and the second connecting tube 126 can form a wiring channel 121 extending along the length direction of the slot 111, so that the collection line 230 can pass through the wiring channel 121 directly, avoiding the collection line 230 from being entangled with each other during routing, and also avoiding the first connecting tube 125 and the second connecting tube 126 from causing the collection lines 230 in the wiring channel 121 to be entangled with each other during rotation, thereby preventing the collection lines 230 from causing safety accidents due to entanglement.

[0053] like Figures 7 to 10 As shown, there are multiple first connecting tubes 125 and multiple second connecting tubes 126 , and a receiving groove 130 for receiving the second connecting tube 126 is provided between two adjacent first connecting tubes 125 . The multiple first connecting tubes 125 and the multiple second connecting tubes 126 are alternately distributed along the length direction of the card slot 111 .

[0054] It should be understood that, during the assembly process, the plurality of second connecting tubes 126 correspond to the plurality of receiving grooves 130 , and each second connecting tube 126 can be assembled into the corresponding receiving groove 130 , which can improve the space utilization between the plurality of first connecting tubes 125 .

[0055] like Figures 7 to 10 As shown, the slot 111 includes a plurality of slot sections 1111 that are spaced apart. In two adjacent slot sections 1111, one slot section 1111 cooperates with the first connecting tube 125, and the other slot section 1111 cooperates with the second connecting tube 126. In this way, when the first connecting tube 125 and the second connecting tube 126 rotate in different slot sections 1111, they will not interfere with each other, and the rotation process is smoother.

[0056] It should be understood that the distance between two adjacent slot segments 1111 can be set according to actual conditions, and the embodiment of the present application does not specifically limit this.

[0057] like Figure 8 and Fig. 9 As shown, the collection line 230 is provided with a collection piece 250, and the first connecting tube 125 and / or the second connecting tube 126 are provided with a through hole 128, through which the collection piece 250 can pass through the routing channel 121, and the passed portion can be used to connect the bar piece 240. In other words, the through hole 128 can assist the collection piece 250 in connecting the collection line 230 and the bar piece 240, so that the collection line 230 can collect the parameters of the bar piece 240 when it is working.

[0058] In one embodiment, the through hole 128 may be provided on the first connecting tube 125 ; or the through hole 128 may be provided on the second connecting tube 126 ; or the through hole 128 may be provided on both the first connecting tube 125 and the second connecting tube 126 .

[0059] In one embodiment, the through hole 128 is disposed on a side of the first connecting tube 125 and / or the second connecting tube 126 close to the bar sheet 240 , which can reduce the extension length of the collection sheet 250 , facilitate the connection of the collection sheet 250 to the bar sheet 240 , and reduce the manufacturing cost of the collection sheet 250 .

[0060] In one embodiment, the collection sheet 250 and the bar sheet 240 can be fixed by heat rivets, which is beneficial to improve the connection stability between the collection sheet 250 and the bar sheet 240 and ensure that the collection line 230 can accurately collect the temperature of the bar sheet 240 through the collection sheet 250.

[0061] like Figure 8 and Fig. 9 As shown, a limiting groove 129 is provided on the first isolation plate 123 and / or the second isolation plate 124, and the collecting piece 250 extending from the through hole 128 can be accommodated in the limiting groove 129. On the one hand, the space in the thickness direction of the first isolation plate 123 and / or the second isolation plate 124 can be utilized to improve space utilization; on the other hand, the limiting groove 129 can limit the collecting piece 250, which can effectively prevent the collecting piece 250 from shaking or detaching from the bar piece 240.

[0062] In one embodiment, a through hole 128 is provided on the first connecting pipe 125 , and correspondingly, a limiting groove 129 is provided on the first isolation plate 123 .
