Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0044] Firstly, such as Figures 1-4As shown, an embodiment of this application provides a data acquisition component 100 applied to a battery module. The battery module includes battery cells (not shown), a busbar 210, and a housing 220. Multiple battery cells are disposed within the housing 220, and the busbar 210 is used to connect the multiple battery cells. The data acquisition component 100 includes a main body segment 110, an extension segment 120, and a first bending structure 130. At least one data acquisition terminal 111 is provided on the main body segment 110, which is used to connect to the battery cells and / or the busbar 210. A connecting structure 121 is provided on the extension segment 120, which is used to connect to the battery cells and / or the housing 220 to fix the data acquisition component 100. The extension direction of the main body segment 110 and the extension direction of the extension segment 120 are set at an angle. The acquisition terminal 111 on the main body 110 can acquire parameters of the battery cell, and the connection structure 121 on the extension 120 can fix the acquisition component 100. The connection structure 121 effectively fixes the acquisition component 100, reducing the excessive space occupation caused by the use of plastic brackets in traditional technologies. The extension directions of the main body 110 and the extension 120 are set at an angle, thereby enabling the connection structure 121 on the extension 120 to connect with the battery cell and / or the housing 220, ensuring connection stability and reducing layout space. In other words, the acquisition component 100 provided in this embodiment can reduce the space occupied within the battery module while ensuring connection stability, thus improving space utilization.
[0045] The battery cells can be cylindrical or prismatic, and are arranged inside the housing, allowing for series or parallel connection as needed. The data acquisition unit 100 can collect parameters such as temperature, voltage, and current of the battery cells.
[0046] For example, the main body segment 110 and the extension segment 120 can be connected by a first bending structure 130, so that the extension directions of the main body segment 110 and the extension segment 120 are set at an angle.
[0047] In some embodiments, the extension segment 120 includes a first extension sub-segment 122 and a second extension sub-segment 124 that are connected to each other, and the extension directions of the first extension sub-segment 122 and the second extension sub-segment 124 are set at an angle.
[0048] That is, the extension section 120 includes a first extension sub-segment 122 and a second extension sub-segment 124 with different extension directions. By setting the extension directions of the first extension sub-segment 122 and the second extension sub-segment 124 at an angle, the outgoing direction of the extension section 120 can be adjusted as needed, which facilitates the arrangement of the acquisition component 100.
[0049] In some embodiments, such as Figure 2As shown, the extension segment 120 also includes a first folding structure 123. One end of the first extension sub-segment 122 is connected to the main body segment 110 via a first bending structure 130, and the other end of the first extension sub-segment 122 is connected to the second extension sub-segment 124 via the first folding structure 123. The main body segment 110 extends along a first direction X, the first extension sub-segment 122 extends along a second direction Z, and the second extension sub-segment 124 extends along a third direction Y. The first direction X, the second direction Z, and the third direction Y intersect each other.
[0050] One end of the first extension segment 122 is connected to the main body segment 110 via the first bending structure 130, allowing the first extension segment 122 and the main body segment 110 to extend in different directions. As shown in the figure, the main body segment 110 extends along the first direction X, and the first extension segment 122 extends along the second direction Z, which facilitates the arrangement of the acquisition component 100 and allows the extension segment 120 to correspond to the cell or housing 220 in the battery module. The connection between the extension segment 120 and the cell and / or housing 220 can be easily achieved through the connection structure 121, ensuring the connection stability of the acquisition component 100 in the battery module.
[0051] The other end of the first extension segment 122 is connected to the second extension segment 124 via the first folding structure 123, which allows the extension directions of the first extension segment 122 and the second extension segment 124 to be different. As shown in the figure, the first extension segment 122 extends along the second direction Z, and the second extension segment 124 extends along the third direction Y. This changes the extension direction of the extension segment 120 within the housing 220. On the one hand, it increases the contact area between the extension segment 120 and the battery cell and / or housing 220, achieving a good connection between the extension segment 120 and the battery cell and / or housing 220 and ensuring connection stability. On the other hand, by changing the extension direction of the extension segment 120 within the housing 220 and arranging the extension segment 120, it reduces the space occupied by the acquisition component 100 within the battery module, reduces the difficulty of arrangement, and saves costs.
[0052] For example, such as Figures 1-2As shown, the main body segment 110 is located on top of the battery module and extends along the first direction X at the top of the battery module, facilitating the electrical connection of the acquisition terminal 111 on the main body segment 110 with the battery cell and / or busbar 210, thereby realizing signal acquisition. Through the first bending structure 130, the first extension segment 122 can contact the side wall of the housing 220, and the first extension segment 122 can extend along the second direction Z towards the bottom of the battery module. Through the first folding structure 123, the second extension segment 124 can extend along the third direction Y, thereby contacting the side wall of the housing 220 and changing the extension direction. This ensures connection stability while adjusting the outgoing wire direction of the acquisition component 100, reducing the difficulty of arranging the acquisition component 100.
[0053] In some embodiments, such as Figures 1-2 As shown, the connection structure 121 includes an adhesive. The adhesive is disposed on at least one surface of the second extension segment 124.
[0054] The second extension segment 124 can be bonded to the battery cell and / or housing 220 in the battery module using an adhesive, thereby fixing the second extension segment 124. Figure 2 As shown, one surface of the second extension segment 124 is close to the battery cell, while the other surface is close to the inner wall of the housing 220. When an adhesive is provided on the surface of the second extension segment 124 near the battery cell, the second extension segment 124 can be bonded to the battery cell. When an adhesive is provided on the surface of the second extension segment 124 near the housing 220, the second extension segment 124 can be bonded to the housing 220. When adhesives are provided on both surfaces of the second extension segment 124, the second extension segment 124 can be bonded to both the battery cell and the housing 220 simultaneously.
[0055] In some embodiments, the second extension segment 124 includes a first surface near the main body segment 110 and a second surface away from the main body segment 110. An adhesive is disposed on the second surface. Disposing the adhesive on the second surface facilitates the connection and fixation of the adhesive to the housing 220 when the acquisition assembly 100 is arranged within the battery module, simplifying the arrangement and ensuring connection stability.
[0056] In some embodiments, the adhesive includes a foam structure, and adhesive layers are provided on opposite sides of the foam structure. By using a foam structure with adhesive layers as the adhesive, bonding can be achieved while also providing a cushioning effect, enabling a soft connection between the second extension segment 124 and the battery cell and / or housing 220, reducing damage caused by collisions and other events.
[0057] In some embodiments, such as Figures 4-5As shown, the housing 220 is provided with a receiving groove 221, which is used to accommodate at least a portion of the extension segment 120. By providing the receiving groove 221 on the housing 220, at least a portion of the extension segment 120 can be accommodated, so that at least a portion of the extension segment 120 is embedded in the receiving groove 221, ensuring the stability of the connection between the extension segment 120 and the housing 220, while also reducing the space occupied by the extension segment 120 in the battery module and improving space utilization.
[0058] By placing at least a portion of the extension 120 within the receiving groove 221, the extension 120 can be limited by the receiving groove 221 to prevent the extension 120 from shifting. At the same time, the receiving groove 221 can also reduce the space occupied by the extension 120 within the housing 220, thereby improving space utilization.
[0059] It is understood that the position of the receiving groove 221 is set to correspond to the extension section 120. The receiving groove 221 can accommodate the entire extension section 120 or a part of the extension section 120.
[0060] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, the acquisition component 100 also includes an output terminal 140. The output terminal 140 is located at the end of the extension 120 away from the main body 110.
[0061] The signal parameters acquired by the acquisition component 100 can be output to other management elements via the output terminal 140. The output terminal 140 is located at the end of the extension section 120 away from the main body section 110. The output terminal 140 can be connected to the main body section 110 via the extension section 120 and outputs the signal parameters acquired by the acquisition terminal 111. The output direction of the acquisition component 100 can be adjusted via the extension section 120, and the position of the output terminal 140 can be reasonably arranged as needed, reducing the difficulty of arrangement.
[0062] In some embodiments, such as Figure 2 and Figure 6 As shown, the output terminal 140 is located on the outside of the housing 220, and the extension section 120 is also provided with a second folding structure 125 and a second bending structure 126. The output terminal 140 is connected to the second extension section 124 through the second bending structure 126 and the second folding structure 125.
[0063] By placing the output terminal 140 on the outside of the housing 220, it is easy to connect the output terminal 140 to other components. The second folding structure 125 and the second bending structure 126 provided on the extension section 120 can adjust the extension direction of the extension section 120, thereby enabling the output terminal 140 to be located on the outside of the housing 220.
[0064] It is understood that those skilled in the art can reasonably set the positions of the second bending structure 126 and the second folding structure 125 according to actual needs, and can also choose to set more bending structures and folding structures. For example, as shown in the figure, a third bending structure 127 is also provided on the extension section 120 so that the extension section 120 bends from the side wall of the housing 220 to the front wall of the housing 220, and the output terminal 140 is arranged on the front wall of the housing 220.
[0065] In some embodiments, such as Figure 3 As shown, the main body segment 110 includes a plurality of main body sub-segments 112 connected sequentially along its length. At least some of the main body sub-segments 112 are provided with acquisition terminals 111, and the extension directions of adjacent main body sub-segments 112 intersect each other.
[0066] By intersecting the extension directions of adjacent main body segments 112, a serpentine arrangement of main body segments 110 can be formed, which can disperse the mechanical stress of the main body segments 110, improve the structural strength of the main body segments 110, and adapt to the layout within the battery module, enabling flexible electrical connections and reducing connection difficulty.
[0067] In some embodiments, such as Figure 3 As shown, the acquisition terminals 111 on adjacent main body sub-segments 112 are arranged alternately on opposite sides of the extension direction of the main body segment 110.
[0068] By staggering the acquisition terminals 111 on adjacent main body segments 112, the connection difficulty between the acquisition terminals 111 and the battery cells can be reduced when the battery module cells are densely arranged, thus reducing the phenomenon of limited local space caused by unilateral arrangement. In addition, the staggered arrangement of acquisition terminals 111 can also balance the current path in the main body segment 110 and reduce signal interference, and can also reduce the risk of poor heat dissipation caused by the concentration of acquisition terminals 111.
[0069] In some embodiments, the battery module further includes an insulating film 230. The insulating film 230 is disposed on the side of the busbar 210 opposite to the battery cell, and the main body segment 110 is disposed between the insulating film 230 and the busbar 210.
[0070] The insulating film 230 provides insulation protection for the bus 210, reducing the risk of short circuits. In addition, the main body section 110 is disposed between the insulating film 230 and the bus 210, and can be fixed by the insulating film 230 and the bus 210, improving the connection stability of the acquisition component 100.
[0071] The insulating film 230 can be connected to the busbar 210 by means of bonding, etc., providing insulation protection for the busbar 210, while allowing the main body section 110 to be sandwiched between the insulating film 230 and the busbar 210, so that the main body section 110 is connected to the insulating film 230 and the busbar 210, thereby improving the stability of the acquisition component 100.
[0072] In some embodiments, the housing 220 is filled with a foam structure. The battery cell, busbar 210, and acquisition assembly 100 are fixed to the housing 220 by the foam structure.
[0073] The foam structure filling the housing 220 can fill the gaps between the housing 220 and the battery cells, between the housing 220 and the busbar 210, and between adjacent battery cells. The expansion pressure secures multiple components and provides a certain buffering effect. Because the extension 120 of the acquisition component 100 is equipped with a connection structure 121, the connection stability between the extension 120 and the battery cells and / or the housing 220 is ensured. When the housing 220 is filled with the foam structure, the pushing effect on the acquisition component 100 caused by the expansion of the foam structure is reduced.
[0074] Secondly, embodiments of this application provide a battery module including the acquisition component 100 as described above.
[0075] The battery module provided in this application embodiment has all the beneficial effects of the acquisition component 100 as described above, and will not be repeated here.
[0076] Thirdly, embodiments of this application also provide a battery pack, including the battery module as described above.
[0077] The battery pack provided in this application embodiment has all the beneficial effects of the acquisition component 100 as described above, and will not be repeated here.
[0078] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
