[0030] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application. According to the embodiments of the present application, an integrated busbar 100, a battery pack and a vehicle are described.

[0031] Reference Figures 1-4 To understand the integrated busbar 100 according to the embodiments of the present application, it includes a first bracket 110, a second bracket 120 and a connector 300 arranged on the second bracket 120.

[0032] In combination Figure 1 It is understood that the first bracket 110 extends along a first direction, one end of the second bracket 120 is connected with the first bracket 110, and the second bracket 120 is movably arranged on the first bracket 110 to switch between a first position and a second position, in the first position, the second bracket 120 extends along the first direction, in the second position, the second bracket 120 extends along a second direction, and the first direction and the second direction have an included angle.

[0033] It should be noted that the integrated busbar 100 is usually assembled into the battery pack and is used to realize the electrical connection between adjacent battery cells and adjacent battery modules. It can also collect voltage and temperature data of the battery pack. That is, the integrated busbar usually includes an integrated busbar support (such as the first support and the second support), a cell busbar, an output busbar, a flexible printed circuit (FPC), a negative temperature coefficient thermistor (NTC), a nickel strip, and the aforementioned connector 300, etc.

[0034] refer to Figure 1 It is understood that the first bracket 110 is located at the end of the integrated busbar 100, the second bracket 120 is connected to the first bracket 110, the connector 300 is disposed on the second bracket 120, and the second bracket 120 can be switched between a first position and a second position. In the first position, the second bracket 120, the integrated busbar 100 and the first bracket are in the same plane. In the second position, the second bracket 120 is at an angle to the first bracket 110, and the connector 300 located on the second bracket 120 can be extended to a suitable position on the battery pack.

[0035] Therefore, the second support 120 in the first position can be on the same plane as the first support 110. In this way, multiple integrated busbars 100 can be stacked along their thickness direction to facilitate material accumulation during the production process of the integrated busbars 100 and reduce the space occupied by the integrated busbars 100 during transportation, thereby reducing transportation costs.

[0036] When the second bracket 120 switches from the first position to the second position, the second bracket 120 switches to: extending along a second direction at an angle to the first direction, so that the second bracket 120 can be installed in the battery pack at an appropriate angle, and the connector 300 located on the second bracket 120 can be located at the corresponding position in the battery pack, so as to facilitate the connector 300 to be plugged into the wiring harness of the surrounding components.

[0037] Specifically, the second support 120 is movably disposed on the first support 110 to achieve switching between the first position and the second position. In order to achieve a movable connection, a variety of different structures can be adopted.

[0038] For example, setting Figure 1 The pivot 200 shown forms a pivot connection structure to enable the second support 120 to rotate relative to the first support 110.

[0039] It is worth noting that existing integrated busbars 100 are constructed using a one-time breakage or other irreversible bending methods to achieve bending. However, the integrated busbar 100 of this embodiment utilizes a movable connection structure between the first support 110 and the second support 120, rather than the irreversible assembly action of existing structures. Therefore, after disassembling the integrated busbar 100, the second support 120 can be reset to the first position, allowing the first support 110 and the second support 120 of the integrated busbar 100 to still switch between the first and second positions, thus enabling the reuse of the integrated busbar 100.

[0040] In other words, since the second bracket 120 is movably mounted on the first bracket 110, the second bracket 120 can be switched from the second position back to the first position.

[0041] For example, adopt Figures 2-4 The pivot connection structure of the rotating shaft 200 shown allows the second bracket 120 to rotate relative to the first bracket 110 via the rotating shaft 200. This allows the second bracket 120 to rotate to a second position during assembly, forming the desired angle. Therefore, after the integrated busbar 100 is disassembled, it can return to the first position by rotating in the opposite direction. Thus, when it is necessary to remove the mounter bracket 100 or redeploy the mounter bracket 100 to another battery pack, the first bracket 110 and the second bracket 120 can be restored to a state where both are in the first direction, i.e., the second bracket 120 is in the first position.

[0042] Furthermore, after the second bracket 120 is bent and returned to the first position, the second bracket 120 and the first bracket 110 are restored to the same plane. The restored integrated busbar 100 is suitable for storage and transportation again. The second bracket 120 in the restored integrated busbar 100 can be switched back to the first position 100 to be reassembled into another battery pack.

[0043] According to the embodiments of this application, the integrated busbar 100 achieves switching between a first position and a second position by setting a first bracket 110 and a second bracket 120 that can be movably connected. The second bracket 120 is suitable for mounting the connector 300. In the first position, the second bracket 120 is on the same plane as the first bracket 110, which reduces the space occupied by the integrated busbar 100 during transportation. In the second position, it is suitable to form an angle with the first bracket 110 to facilitate matching with the battery pack. The switching between the first position and the second position does not cause structural damage, so that the integrated busbar 100 can be reused to reduce costs.

[0044] In some embodiments, combined with Figures 2-4As shown, the first support 110 is provided with a first connecting piece, the second support 120 is provided with a second connecting piece, and the first connecting piece and the second connecting piece are pivotally connected through the rotating shaft 200. Among them, the rotating shaft 200 realizes the rotating connection between the first connecting piece and the second connecting piece, and the first connecting piece and the second connecting piece rotate relative to each other to adapt to the switching of the second support 120 between the first position and the second position.

[0045] It can be understood that the first support 110 and the second support 120 are pivotally connected through the rotating shaft 200, which can allow the second support 120 to freely switch between the first position and the second position, so that the second support 120 can be switched back from the second position to the first position through the rotating connection, avoiding the problem that the integrated busbar 100 cannot be restored after assembly.

[0046] For example, referring to Figure 2 As shown, the first connecting piece is configured as two first plates 111 arranged oppositely, the second connecting piece is configured as a connecting column 121, and the connecting column 121 is arranged between the two first plates 111. The connecting column 121 is provided in the first plate 111 to form the rotating shaft 200.

[0047] Specifically, the first support 110 includes a first support body 112 and two first plates 111, which are defined as a first sub-plate 1111 and a second sub-plate 1112, respectively. The first support body 112 is a plate structure and extends the first sub-plate 1111 and the second sub-plate 1112 at one side edge of the first support body 112. Among them, the first sub-plate 1111 and the second sub-plate 1112 are arranged in parallel, and the first sub-plate 1111 and the second sub-plate 1112 are provided with fixing holes 210. The axis of the two fixing holes 210 is parallel to the plate edge of the first support body 112, and the fixing hole 210 on the first sub-plate 1111 and the fixing hole 210 on the second sub-plate 1112 are coaxially arranged to adapt to the connecting column 121.

[0048] For example, referring to Figure 3 As shown, the second support 120 includes a second support body 122 and a connecting column 121. The connecting column 121 includes a body segment 1211 and a matching segment 1212 formed at both ends of the body segment 1211. The body segment 1211 is a column structure, and the matching segment 1212 is a column structure with a smaller diameter than the body segment 1211. The matching segment 1212 is inserted into the fixing hole 210 to rotate as a pin in the fixing hole 210, so that the rotating shaft 200 is formed between the first connecting piece and the second connecting piece to pivotally connect them.

[0049] Further combined with Figure 4It is understood that the first support 110 serves as a stable support structure and extends in the first direction, and the second support 120 is pivotally connected to the first connecting piece through the connecting column 121. When it is necessary to switch the second support 120 to the second position, since the body segment 1211 is connected to the second support body 122 as an integral structure, and the matching segment 1212 serves as a pin piece and rotates in the fixed hole 210, the second support 120 can be rotated towards the second direction having an included angle with the first direction.

[0050] Conversely, when it is necessary to reset the second support 120, the second support 120 can be switched back to the first position from the second position by being reversely rotated, and the specific process will not be described herein.

[0051] In some embodiments, the first sub-plate 1111 and the second sub-plate 1112 are provided with limiting portions, and the end surface of the connecting column 121 is provided with a first positioning portion and a second positioning portion matched with the limiting portions. In the first position, the first positioning portion is inserted and matched with the limiting portions, and in the second position, the second positioning portion is inserted and matched with the limiting portions. Figures 2-4 As shown, the first sub-plate 1111 and the second sub-plate 1112 are provided with limiting portions, and the end surface of the connecting column 121 is provided with a first positioning portion and a second positioning portion matched with the limiting portions. In the first position, the first positioning portion is inserted and matched with the limiting portions, and in the second position, the second positioning portion is inserted and matched with the limiting portions.

[0052] Specifically, the limiting portion can be a protrusion, a groove or other shapes capable of being inserted and matched with the positioning portion, and the position and number of the limiting portion can be one or more. Through the matching of the limiting portion with the first positioning portion or the second positioning portion, stable matching with the corresponding positioning portion can be ensured when the second support 120 is rotated to the first position or the second position.

[0053] When the second support 120 is in the first position, the first positioning portion on the end surface of the connecting column 121 is inserted and matched with the limiting portion, so as to prevent the second support 120 from moving or rotating in the first direction and ensure the stability of the second support 120 in the first position. Similarly, when the second support 120 is in the second position, the second positioning portion on the end surface of the connecting column 121 is inserted and matched with the limiting portion, so as to prevent the second support 120 from moving or rotating in the second direction and ensure the stability of the second support 120 in the second position.

[0054] In different examples, the specific structure of the limiting portion and the first and second positioning portions is not limited to the form of plug-in cooperation, and other structures can also be used to achieve stable positioning and cooperation. For example, the limiting portion can be configured in the form of a card slot, which can be long strip-shaped, circular or other shapes, and the inner space is used to accommodate a buckle. The first and second positioning portions are configured in the form of buckles to be inserted into the card slot and kept stable. For another example, the limiting portion can be a permanent magnet or an electromagnet embedded on the first plate 111, and the first and second positioning portions are configured as ferromagnetic materials that are attracted to the permanent magnet or electromagnet. When the second support 120 is rotated to a predetermined position (the first position or the second position), stable cooperation is achieved through magnetic attraction.

[0055] Next, taking the limiting portion as a limiting protrusion 220, and the first and second positioning portions as limiting recesses 230, the following will be described in combination with Figures 2-4 .

[0056] Specifically, the first and second sub-plates 1111 and 1112 are both formed in the shape of a circular plate body, and the side of the first sub-plate 1111 relative to the second sub-plate 1112 and the side of the second sub-plate 1112 relative to the first sub-plate 1111 are both configured with a limiting protrusion 220. The limiting protrusion 220 is an arc-shaped protrusion structure, and the arc-shaped surface formed thereon extends along the rotation direction of the connecting column 121 relative to the first and second sub-plates 1111 and 1112, and forms a smooth arc-shaped transition with the transition area of the first and second sub-plates 1111 and 1112, so that the arc-shaped protrusion can smoothly slide on the end surface of the connecting column 121 through the arc-shaped surface.

[0057] Correspondingly, a limiting recess 230 is configured on the end surface of the cooperation section 1212 of the connecting column 121, and the structure of the limiting recess 230 matches that of the limiting protrusion 220. The limiting recess 230 includes a first limiting recess 231 and a second limiting recess 232, the first limiting recess 231 corresponds to the switching of the second support 120 to the first position, and the second limiting recess 232 corresponds to the switching of the second support 120 to the second position.

[0058] Optionally, the first and second plates 111 and 112 are configured with a material such as plastic that has elasticity, so as to achieve the switching of the arc-shaped protrusion between the first and second limiting recesses 231 and 232. Specifically, since the first and second sub-plates 1111 and 1112 are made of elastic material, they have certain deformation ability and restoring force. When the second support 120 needs to be switched between the first and second positions, the arc-shaped protrusion will contact and press the end surface of the connecting column and produce elastic deformation, so as to facilitate the position switching.

[0059] For example, when it is needed to switch to the second position, the user applies a rotating force to make the second support 120 start rotating. In some cases, the first sub-plate 1111 and the second sub-plate 1112 are both elastic, and the arc-shaped protrusion is pressed by the end face of the connecting column 121 and deformed, so as to smoothly slide through the end face of the connecting column 121 and be separated from the first limiting groove 231.

[0060] Further, with the continuous rotation of the second support 120, the arc-shaped protrusion gradually approaches and contacts the second limiting groove 232. Due to the restoring force of the elastic material, the arc-shaped protrusion is naturally clamped into the second limiting groove 232 when it contacts the second limiting groove 232. In this way, when the second support 120 is completely rotated to the second position, the arc-shaped protrusion and the second limiting groove 232 form a new plug-in fit, ensuring the stability of the second support 120 in the second position.

[0061] Conversely, when it is needed to disassemble or redeploy the integrated busbar 100, the second support 120 needs to be switched from the second position back to the first position. The arc-shaped protrusion is separated from the second limiting groove 232 under the action of the elastic material, and gradually approaches and is clamped into the first limiting groove 231 with the rotation of the second support 120, and the specific process is not repeated.

[0062] Of course, the limiting part can also be configured as a limiting groove 230, and the first positioning part and the second positioning part can also be configured as a limiting protrusion 220, and the specific principle is basically the same as the foregoing example.

[0063] In some embodiments, the first positioning part and the second positioning part have a first included angle, and the angle of the first included angle is consistent with the included angle between the first direction and the second direction. In other words, the included angle between the first direction and the second direction is the angle between the two directions (i.e., the first direction and the second direction) along which the second support 120 respectively moves in the first position and the second position, and then the first positioning part and the second positioning part have a first included angle equal to the same, which can ensure that when the second support 120 is switched between the first position and the second position, the first positioning part and the second positioning part can correspondingly position the second support 120 to the first position or the second position.

[0064] For example, the included angle between the first positioning part and the second positioning part is 90°, that is, the angle between the first limiting groove 231 and the second limiting groove is 90°, and correspondingly, the included angle between the first direction and the second direction is 90°.

[0065] It is understandable that the first included angle is consistent with the included angle between the first direction and the second direction, which can ensure that when the second bracket 120 rotates to the first position or the second position, the positioning part can position the position of the second bracket 120, so that it is accurately positioned to the first position when it cooperates with the first positioning part, and accurately positioned to the second position when it cooperates with the second positioning part.

[0066] In a further embodiment, the integrated busbar 100 also includes a signal acquisition harness and an electrical connection part.

[0067] In some examples, reference Figure 1 As shown, the electrical connection portion is connected to the first bracket 110. The electrical connection portion includes several female connectors 310 for connecting to a signal acquisition harness (not shown in the figure). For example, the signal acquisition line is provided with terminals (not shown in the figure), which, when mated with the female connectors 310, form an information loop. The signal acquisition harness is suitable for acquiring the operating signals of individual battery cells. Thus, the signal acquisition harness is electrically connected to the connector 300 via the female connectors 310 (forming the electrical connection portion), allowing the electrical connection portion to be used for series or parallel connection of adjacent battery cells or adjacent battery modules, and to acquire the operating status of the battery cells via the signal acquisition lines.

[0068] Of course, the electrical connection can be like Figure 1 As shown, the components are assembled to the first bracket 110 and the second bracket 120. In other examples, they may also be integrated with the first bracket 110 and the second bracket 120. For example, the first bracket 110 and the second bracket 120 may have embedded signal acquisition lines and electrical connection parts. The signal acquisition harness is disposed within the first bracket 110 and the second bracket 120 and is suitable for acquiring the operating signals of the battery cells. The other end of the signal acquisition harness is connected to the electrical connection part located within the first bracket 110 or the second bracket 120, so that the electrical connection part can acquire the operating status of the battery cells.

[0069] The battery pack according to the embodiments of this application includes a plurality of battery cells, or at least one battery module, and an integrated busbar 100 as described in the foregoing embodiments. The integrated busbar 100 is electrically connected and signal connected to the battery module.
