[0039] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are merely intended to explain the present application, and are not to be understood as limiting the present application.

In addition, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0041] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The cross-over sheet 30 of the integrated busbar 100, the integrated busbar 100, the battery module 200 and the battery pack 1000 according to the embodiments of the present application are described below with reference to the drawings.

[0043] As Figure 1 , Figure 3 andFigure 4 As shown, the integrated busbar 100 according to the embodiment of the utility model, include: signal acquisition piece 10, multiple outgoing sheet 20 and cross piece 30. Multiple outgoing sheet 20 is connected to signal acquisition piece 10 respectively, cross piece 30 is connected to signal acquisition piece 10, and cross piece 30 is equipped with interconnection part 31, when the adjacent two integrated busbars 100 are connected, the cross piece 30 on two integrated busbars 100 is connected through interconnection part 31. Among them, outgoing sheet 20 and cross piece 30 are staggered along the edge of signal acquisition piece 10 to connect the different pole of battery module 200.

[0044] It can be understood that multiple outgoing sheet 20 and cross piece 30 are connected to the pole of battery module 200, and signal acquisition piece 10 is connected to multiple outgoing sheet 20 and cross piece 30 simultaneously to realize that signal acquisition piece 10 collects information (such as voltage) of different poles of battery module 200. When two integrated busbars 100 are connected, two integrated busbars 100 form conduction through the interconnection part 31 of cross piece 30, thereby realizing synchronous information collection of two integrated busbars 100.

[0045] Therefore, cross piece 30 is connected to signal acquisition piece 10, and cross piece 30 is directly connected to the pole, when two integrated busbars 100 need to be connected, only the corresponding cross piece 30 of two integrated busbars 100 needs to be connected in interconnection part 31, which can simplify the operation of connecting two integrated busbars 100 through cross piece 30. At the same time, cross piece 30 is connected to the pole and signal acquisition piece 10 simultaneously, so that cross piece 30 can play the role of outgoing sheet 20, without setting an additional connection structure between the pole and signal acquisition piece 10, thereby reducing the connection times of cross piece 30 when it is set in integrated busbar 100, improving the reliability and stability of cross piece 30 when it is set in integrated busbar, and simplifying the connection structure of cross piece 30 set in integrated busbar 100, reducing the setting cost of cross piece 30 and the operation difficulty of setting cross piece 30 in integrated busbar 100.

[0046] The integrated busbar 100 of the application can simplify the connection structure of cross piece 30 in integrated busbar 100 by setting cross piece 30 to connect signal acquisition piece 10 and the pole simultaneously, and integrating cross piece 30 in integrated busbar 100, which can reduce the setting cost of cross piece 30 and simplify the setting operation of cross piece 30 in integrated busbar 100. At the same time, the adjacent two integrated busbars 100 are connected through the interconnection part 31 of cross piece 30, which can simplify the connection operation of two integrated busbars 100.

[0047] It should be noted that the number of cross pieces 30 included in the integrated busbar 100 is not limited in the application, and the number of cross pieces 30 included in each integrated busbar 100 can be set according to the number of other integrated busbars 100 connected. For example, in the embodiment of the utility model, the number of cross pieces 30 included in each integrated busbar 100 is equal to the number of other integrated busbars 100 connected.Figure 4 In the example, each integrated busbar 100 is connected to only one other integrated busbar 100, that is, each integrated busbar 100 is provided with a corresponding jumper 30. For another example, when an integrated busbar 100 is connected to two other integrated busbars 100, two jumper 30s are provided on that integrated busbar 100.

[0048] Preferably, the thickness of the bridging piece 30 is the same as the thickness of the lead piece 20, thereby improving the consistency of conductivity between the bridging piece 30 and the lead piece 20. At the same time, the distances from the bridging piece 30 and the lead piece 20 to the signal acquisition device 10 are relatively consistent, so that the signal acquisition device 10 can connect the bridging piece 30 and the lead piece 20 through the same structure. Therefore, the same signal acquisition device 10 can be used for integrated busbars 100 with different numbers of lead pieces 20 or integrated busbars 100 with different bridging piece 30 positions, thereby improving the versatility of the signal acquisition device 10 and reducing the manufacturing cost of the integrated busbar 100.

[0049] In some embodiments, such as Figure 2 , Figure 5 As shown, the jumper 30 has a first edge 32 and a second edge 33. The first edge 32 is disposed toward the signal acquisition unit 10, and the second edge 33 constitutes an interconnection part 31 for splicing and connecting with the second edge 33 of the jumper 30 on another integrated busbar 100.

[0050] Therefore, the bridging pieces 30 of two adjacent integrated busbars 100 can be connected and spliced ​​together at the second edge 33. The second edge 33 can guide the splicing position of the two bridging pieces 30, reducing the difficulty of connecting the two integrated busbars 100 through the bridging pieces 30.

[0051] Meanwhile, the first edge 32 is set to face the signal acquisition device 10, and the second edge 33 forms the interconnection part 31. That is, the second edge 33 does not face the signal acquisition device 10, so that the splicing direction of the two jumper pieces 30 can avoid the signal acquisition device 10. When the two jumper pieces 30 are spliced, the jumper pieces 30 will not be blocked by the signal acquisition device 10 in space.

[0052] Preferably, when two bridging pieces 30 are spliced ​​together at their second edges 33, the second edges 33 of the two bridging pieces 30 overlap, thereby allowing for a larger contact area between the two bridging pieces 30 and improving the connection stability between the two bridging pieces 30.

[0053] Furthermore, the two bridging pieces 30 are welded together at their second edges 33. When the second edges 33 of the two bridging pieces 30 overlap, the welding line length of the two bridging pieces 30 at their second edges 33 can be increased, thereby improving the stability of the connection between the two bridging pieces 30.

[0054] Further, at least one of the splicing protrusion 34 and the splicing groove 35 is arranged on the second edge 33. Thus, when the two crosspieces 30 are spliced and connected at the interconnection part 31, the splicing protrusion 34 of one crosspiece 30 is located in the splicing groove 35 of the other crosspiece 30, thereby realizing the splicing and connecting of the two crosspieces 30.

[0055] In addition, when the splicing protrusion 34 is located in the splicing groove 35, the positions of the two crosspieces 30 along the direction of the second edge 33 can be limited, thereby improving the accuracy and stability of the connecting position between the two crosspieces 30.

[0056] In the present application, the shapes of the splicing protrusion 34 and the splicing groove 35 are not limited, as long as the splicing groove 35 can accommodate the splicing protrusion 34. The splicing protrusion 34 and the splicing groove 35 can also be arranged in different shapes.

[0057] Further, when the splicing protrusion 34 is arranged on the second edge 33, the splicing protrusion 34 is trapezoidal. When the splicing groove 35 is arranged on the second edge 33, the splicing groove 35 is trapezoidal.

[0058] It should be noted that when the splicing protrusion 34 is trapezoidal, the side of the splicing protrusion 34 away from the second edge 33 is the longer base of the trapezoid. When the splicing groove 35 is trapezoidal, the base of the splicing groove 35 is the longer base of the trapezoid.

[0059] Thus, when the splicing protrusion 34 is located in the splicing groove 35, the splicing protrusion 34 is not easy to come out of the splicing groove 35, which can improve the stability of the splicing and cooperation of the splicing protrusion 34 and the splicing groove 35, thereby improving the stability of the splicing and connecting of the two crosspieces 30.

[0060] In some embodiments, as shown in FIGS. 1 and 2, the first edge 32 and the second edge 33 are arranged perpendicularly, and the second edge 33 is longer than the first edge 32. Figure 2 Figure 5 It should be understood that the first edge 32 is directed towards the signal acquisition piece 10, and the second edge 33 is perpendicular to the first edge 32. When the two crosspieces 30 are spliced and connected at the second edge 33, the splicing direction of the two crosspieces 30 is perpendicular to the second edge 33. The extension direction of the first edge 32 is parallel to the extension direction of the edge of the signal acquisition piece 10, that is, the interval arrangement direction of the lead-out piece 20 and the crosspiece 30 is consistent with the extension direction of the first edge 32.

[0061] It should be understood that the first edge 32 is directed towards the signal acquisition piece 10, and the second edge 33 is perpendicular to the first edge 32. When the two crosspieces 30 are spliced and connected at the second edge 33, the splicing direction of the two crosspieces 30 is perpendicular to the second edge 33. The extension direction of the first edge 32 is parallel to the extension direction of the edge of the signal acquisition piece 10, that is, the interval arrangement direction of the lead-out piece 20 and the crosspiece 30 is consistent with the extension direction of the first edge 32.

[0062] ​Therefore, the two crosspieces 30 are spliced along the extension direction of the first edge 32, i.e., the two crosspieces 30 are spliced along the extension direction of the edge of the signal acquisition member 10, which can reduce or avoid the splicing of the two crosspieces 30 being blocked by the signal acquisition member 10 in space.

[0063] It should be noted that, in the same battery module 200, the lead-out piece 20 is connected to two pole posts, while the crosspiece 30 is connected to only one pole post in the same battery module 200. When the integrated busbar 100 of the two battery modules 200 is cross-connected, the crosspiece 30 of the integrated busbar 100 needs to extend towards the other battery module 200 and be connected to the pole post of the other battery module 200.

[0064] Therefore, by setting the length of the second edge 33 to be greater than the length of the first edge 32, the size of the crosspiece 30 along the interval arrangement direction of the lead-out piece 20 and the crosspiece 30 can be reduced. On the one hand, the risk of short circuit caused by the structure of the crosspiece 30 and the lead-out piece 20 along the interval arrangement direction thereof can be reduced or avoided. On the other hand, when the two crosspieces 30 are spliced and connected, the two crosspieces 30 are connected to the same pole post, which can ensure that the two crosspieces 30 and the pole post each have sufficient connection area, thereby improving the stability of the connection between the crosspiece 30 and the pole post.

[0065] In addition, by setting at least one lead-out piece 20 and the crosspiece 30 to be arranged at intervals along the extension direction of the first edge 32, and setting the length of the second edge 33 to be greater than the size of the lead-out piece 20 in the extension direction of the second edge 33, the crosspiece 30 can be ensured to extend to the pole post of the adjacent battery module 200 along the extension direction of the second edge 33, so that the crosspiece 30 can be connected to the pole posts of the adjacent two battery modules 200 at the same time.

[0066] Preferably, the crosspiece 30 is in the shape of a rectangular piece.

[0067] In some embodiments, as shown in Figure 2 、 Figure 5 The crosspiece 30 is provided with a through positioning hole 36.

[0068] It can be understood that, when the crosspiece 30 is connected to the pole post, the crosspiece 30 will block the view of the pole post.

[0069] Therefore, the positioning hole 36 penetrates the crosspiece 30, and when the crosspiece 30 covers the pole post, the position of the crosspiece 30 relative to the pole post can be observed through the positioning hole 36. That is, when the pole post can be observed through the positioning hole 36, the crosspiece 30 at least partially covers the pole post. Therefore, the crosspiece 30 at least partially covering the pole post can be observed through the positioning hole 36, thereby ensuring the reliable connection between the crosspiece 30 and the pole post.

[0070] Further, the positioning hole 36 is located on the second edge 33 to form a half hole.

[0071] It can be understood that when the two crosspieces 30 are connected correspondingly, the half holes of the two crosspieces 30 are also connected correspondingly to form a complete hole.

[0072] Therefore, when the half holes of the two crosspieces 30 are opposite and form a complete hole, the two crosspieces 30 are located at the correct connection position. Thus, the half hole can be used to judge whether the connection position of the two crosspieces 30 is accurate, and plays a guiding effect on the connection of the two crosspieces 30, facilitating the connection operation of the two crosspieces 30.

[0073] In some embodiments, as shown in Figure 1 , Figure 3 The signal acquisition piece 10 is a long strip, and a plurality of lead-out pieces 20 and crosspieces 30 are connected to at least one long edge of the signal acquisition piece 10, and the plurality of lead-out pieces 20 and crosspieces 30 are arranged at intervals along the long edge of the signal acquisition piece 10.

[0074] Therefore, the gap when the plurality of lead-out pieces 20 and crosspieces 30 are arranged at intervals can be reduced, thereby increasing the number of the plurality of lead-out pieces 20 and crosspieces 30 that can be arranged on the signal acquisition piece 10. At the same time, the arrangement direction of the plurality of lead-out pieces 20 and crosspieces 30 is consistent, which can improve the relative position stability between the plurality of lead-out pieces 20 and crosspieces 30, thereby reducing or avoiding the risk of short circuit caused by contact between the plurality of lead-out pieces 20 and crosspieces 30.

[0075] It should be noted that the arrangement of the lead-out pieces 20 and crosspieces 30 needs to correspond to the arrangement of the pole columns of the battery module 200. In the above embodiment, the plurality of pole columns of the battery module 200 are arranged along the long edge of the signal acquisition piece 10, and therefore, the plurality of lead-out pieces 20 and crosspieces 30 are also arranged along the plurality of pole columns along the long edge of the signal acquisition piece 10.

[0076] Further, the plurality of lead-out pieces 20 and crosspieces 30 are connected to one long edge of the signal acquisition piece 10, and the plurality of lead-out pieces 20 and the signal output part 11 are connected to the other long edge. The crosspiece 30 and the signal output part 11 are located at both ends of the signal acquisition piece 10 in the length direction.

[0077] It can be understood that the signal acquisition piece 10 is connected to an external circuit structure at the signal output part 11.

[0078] Therefore, the distance between the signal output part 11 and the jumper 30 can be increased, the jumper 30 can reduce or avoid the spatial obstruction to the structure of the external circuit connected to the signal output part 11, the signal acquisition piece 10 can have a larger space for connecting the structure of the external circuit at the signal output part 11, the stability of the signal output part 11 connected to the structure of the external circuit is ensured, and therefore the stability of the signal output by the signal acquisition piece 10 is improved.

[0079] In some embodiments, as shown in Figure 1 、 Figure 3 The signal acquisition piece 10 includes a flexible conductive piece 12 and a plurality of acquisition pieces 13. The plurality of acquisition pieces 13 are connected to the flexible conductive piece 12 along the circumference of the flexible conductive piece 12, and the plurality of acquisition pieces 13 correspond to the plurality of lead-out pieces 20 and the jumper 30 one by one.

[0080] Therefore, the lead-out piece 20 and the jumper 30 are connected to the flexible conductive piece 12 through the acquisition piece 13. Since the flexible conductive piece 12 has a certain bending ability, the setting position of the lead-out piece 20 and the jumper 30 can have a certain error allowance range. The flexible conductive piece 12 can adjust the setting position and bend according to the setting error of the lead-out piece 20 and the jumper 30, so that the lead-out piece 20 and the jumper 30 can be reliably connected to the flexible conductive piece 12 through the acquisition piece 13.

[0081] In the present application, the structure or material of the flexible conductive piece 12 and the acquisition piece 13 is not limited. For example, the flexible conductive piece 12 can be a flexible circuit board or a flexible conductive wire harness. For another example, the acquisition piece 13 is a nickel piece.

[0082] The battery module 200 according to the embodiment of the present application includes the integrated busbar 100 according to the above embodiment. When the integrated busbars 100 of two adjacent battery modules 200 are connected, the two connected jumpers 30 are connected to the same pole of the two battery modules 200.

[0083] The battery module 200 of this application adopts the integrated busbar 100 of the above embodiment. In the same integrated busbar 100, the jumper 30 is connected to the signal acquisition device 10 and the jumper 30 is directly connected to the terminal post. When it is necessary to connect the integrated busbars 100 of two battery modules 200, it is only necessary to connect the corresponding jumper 30 of the two integrated busbars 100 in the interconnection part 31, which simplifies the operation of connecting the two integrated busbars 100 through the jumper 30. Meanwhile, the jumper 30 is connected to both the terminal and the signal acquisition unit 10, enabling the jumper 30 to function as the lead-out piece 20. This eliminates the need for an additional connection structure between the terminal and the signal acquisition unit 10, thereby reducing the number of connections when the jumper 30 is installed on the integrated busbar 100. This improves the reliability and stability of the jumper 30 when it is installed on the busbar, simplifies the connection structure of the jumper 30 on the integrated busbar 100, reduces the installation cost of the jumper 30, and lowers the operational difficulty of installing the jumper 30 on the integrated busbar 100.

In the same battery module 200, the jumper 30 is connected to the signal acquisition unit 10 and the jumper 30 is directly connected to the terminal post. When it is necessary to connect the integrated busbars 100 of two battery modules 200, it is only necessary to connect the corresponding jumper 30 of the two integrated busbars 100 in the interconnection part 31, which simplifies the operation of connecting the two integrated busbars 100 through the jumper 30. Meanwhile, the jumper 30 is connected to both the terminal and the signal acquisition unit 10, enabling the jumper 30 to function as the lead-out piece 20. This eliminates the need for an additional connection structure between the terminal and the signal acquisition unit 10, thereby reducing the number of connections when the jumper 30 is installed on the integrated busbar 100. This improves the reliability and stability of the jumper 30 when it is installed on the busbar, simplifies the connection structure of the jumper 30 on the integrated busbar 100, reduces the installation cost of the jumper 30, and lowers the operational difficulty of installing the jumper 30 on the integrated busbar 100.
