The connecting bar is used to be electrically connected to the battery cells, and the collection harness is electrically connected to the connecting bar for collecting voltage, current and other signals.

[0003] Usually, a voltage collection bar, such as a nickel sheet, is provided on the collection harness for collecting voltage signals. In the prior art, when the collection harness and the connecting bar are installed on the insulating component, since the thickness of the connecting bar is larger than that of the collection harness, when the voltage collection bar is conductively connected to the connecting bar, the voltage collection bar needs to be bent, and the degree of bending needs to ensure that the voltage collection bar can be electrically connected to the side of the connecting bar away from the insulating component. Therefore, the extension length of the voltage collection bar is relatively long to ensure that the connection area with the bus bar after bending meets the design requirements. However, there are a large number of voltage collection bars and connecting bars in the battery module, and the step of bending each voltage collection bar results in a large amount of material used for the voltage collection bar, resulting in an increase in production costs; moreover, the greater the bending degree of the voltage collection bar, the lower its strength will be, and there may be risks of cracking and breaking when the battery module is subjected to variable loads.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] like Figure 1 and Figure 2As shown, the present embodiment provides a collection component, including an insulating component 100, a connecting row 200, a collection harness 300 and a temperature collection component 400. The connecting row 200, the collection harness 300 and the temperature collection component 400 are installed on the insulating component 100, so that the entire collection component forms a whole, and the connecting row 200 is used to be electrically connected to the battery cell, and the connecting row 200 and the temperature collection component 400 are both communicatively connected to the collection harness 300 to collect the voltage signal and temperature signal of the battery cell. During the assembly of the battery module, the entire collection component is loaded as a whole, which can improve the assembly efficiency. The collection component provided in this embodiment can avoid the defect of large collection accuracy error caused by deformation of the insulating component 100, and after the collection harness 300 is installed, it can avoid the phenomenon of the collection harness 300 falling off in the subsequent process.

[0050] like Figure 3 and Figure 4 , which is a schematic diagram of the structure of the insulating component 100 provided in this embodiment. The insulating component 100 has a mounting portion 1 and a slot 22 recessed relative to the mounting portion 1. Figure 2 and Figure 5 The connection row 200 includes a first plate 210 and a second plate 220 that are bent and connected. After the connection row 200 is installed on the insulating component 100, the heights of the first plate 210 and the second plate 220 are inconsistent. The mounting portion 1 is used to mount the first plate 210 and the collection harness 300. The second plate 220 is mounted in the card slot 22. The side of the second plate 220 facing away from the insulating component 100 is closer to the mounting portion 1 of the insulating component 100 than the side of the first plate 210 facing away from the insulating component 100. The collection harness 300 is exemplarily an FPC (flexible printed circuit) on which a voltage collection bar 310 is arranged, see Figure 2 , Figure 5 as well as Figure 6 The side of the second plate body 220 facing away from the insulating component 100 is used to install the voltage collection bar 310. Specifically, the voltage collection bar 310 is conductively connected to the second plate body 220, for example, by laser welding.

[0051] When installing the connection bar 200 and the collection harness 300 on the insulating component 100 , both the connection bar 200 and the collection harness 300 are installed on the mounting portion 1 of the insulating component 100 , and the second plate 220 of the connection bar 200 is engaged with the slot 22 recessed on the mounting portion 1 . On the one hand, the engagement of the second plate body 220 with the card slot 22 can locate the position of the connecting row 200, ensuring the installation stability of the connecting row 200 on the insulating component 100; on the other hand, after the connecting row 200 is installed on the insulating component 100, the side of the second plate body 220 away from the insulating component 100 is closer to the mounting portion 1 than the side of the first plate body 210 away from the insulating component 100, that is, the height of the second plate body 220 relative to the mounting portion 1 is lower than the height of the first plate body 210 relative to the mounting portion 1, and the voltage collection bar 310 on the collection harness 300 located on the mounting portion 1 can be conductively connected to the second plate body 220 of the connecting row 200 without being bent to a large extent or even without being bent. Since the bending degree of the voltage collection bar 310 is reduced or even does not need to be bent, the material usage of the voltage collection bar 310 can be reduced, the production cost can be reduced, the strength loss of the voltage collection bar 310 can be reduced, the service life of the voltage collection bar 310 can be extended, and the reliability of voltage signal collection can be improved.

[0052] See also Figure 6 In the design, it is preferred to design the groove depth of the card slot 22 and the plate thickness of the second plate body 220 to be substantially the same. Since the groove depth of the card slot 22 is substantially the same as the thickness of the second plate body 220, after the second plate body 220 is inserted into the card slot 22, its upper surface is flush with the mounting portion 1, and the voltage collection bar 310 of the collection harness 300 located on the mounting portion 1 can be electrically connected to the second plate body 220 of the connection row 200 without bending. In the assembly stage of the collection component, the step of bending the voltage collection bar 310 can be eliminated, thereby improving production efficiency, reducing production costs, and facilitating mass production.

[0053] Exemplarily, the voltage collection bar 310 is a nickel bar, which has good electrical conductivity and low cost. In some embodiments, the first plate 210 and the second plate 220 of the connecting bar 200 are integrally stamped and formed, and the connection between the two is smoothly transitioned to avoid disconnection due to stress concentration at the connection. The connecting bar 200 is an aluminum bar or a copper bar, etc., as long as it has good electrical conductivity.

[0054] In some embodiments, the mounting portion 1 is recessed with a connected connection row main groove 21 and a wiring harness groove 3, the connection row main groove 21 is engaged with the first plate body 210, the engaging groove 22 is at least partially recessed in the bottom wall of the connection row main groove 21, and the wiring harness groove 3 is used to accommodate the collection harness 300.

[0055] The connecting row main groove 21 and the above-mentioned clamping groove 22 constitute the connecting row installation groove 2, and one connecting row installation groove 2 is provided on the insulating component 100 corresponding to each connecting row 200. The connecting row main groove 21 of the connecting row installation groove 2 is used to clamp the first plate body 210 of the connecting row 200, and the clamping groove 22 of the connecting row installation groove 2 is used to clamp the second plate body 220 of the connecting row 200, which can ensure the installation firmness of the entire connecting row 200 and effectively limit the connecting row 200.

[0056] By providing the harness groove 3 for accommodating the collection harness 300, it is possible to prevent other components from touching or pulling the collection harness 300, thereby providing better protection and limiting effect on the collection harness 300 and preventing the collection harness 300 from falling off. Since the collection harness 300 can remain stable and firm, it is possible to prevent the voltage collection position and the temperature collection position from being pulled and causing collection failure.

[0057] The height difference between the bottom wall surface of the connecting row main groove 21 and the bottom wall surface of the wiring harness groove 3 is less than or equal to 2.5mm. That is, the bottom wall surface of the connecting row main groove 21 and the bottom wall surface of the wiring harness groove 3 can be flush, simplifying the process, and the bottom wall surface of the connecting row main groove 21 and the bottom wall surface of the wiring harness groove 3 can also be not flush, but there is a certain height difference. The height difference is exemplarily greater than or equal to 1.5mm and less than or equal to 2.5mm, and the insulating component 100 will not be excessively deformed during the integral molding. For example, the height difference is 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc.

[0058] In other embodiments, the connecting row main groove 21 and the harness groove 3 may not be provided, and only the above-mentioned card groove 22 may be directly provided on the upper surface of the insulating component 100 .

[0059] See also Figure 4 A first step structure 211 is provided on the groove wall of the connecting row main groove 21, see Figure 7 The connecting bar 200 is provided with a second step structure 230, and the first step structure 211 and the second step structure 230 are interlocked, which helps to further improve the stability of the connecting bar 200 in the connecting bar installation slot 2. Moreover, the first step structure 211 and the second step structure 230 have a foolproof effect, which can prevent the connecting bar 200 from being installed in the wrong position.

[0060] See also Figure 4The groove wall of the connecting row main groove 21 includes a first step surface 1 2111, a first step surface 2112 and a first step surface 3 2113 which are sequentially connected in a Z-shape. For example, the first step surface 1 2111, the first step surface 2112 and the first step surface 3 2113 can be sequentially vertically connected to form the above-mentioned first step structure 211. Figure 7 The side wall of the connection row 200 includes a second step surface 1 231, a second step surface 232 and a second step surface 3 233 which are sequentially connected in a Z-shape. For example, the second step surface 1 231, the second step surface 232 and the second step surface 3 233 can be sequentially vertically connected to form the above-mentioned second step structure 230. Figure 5 , which is a schematic diagram of the first step structure 211 and the second step structure 230 after being embedded, wherein the first step surface 2111 and the second step surface 231 are in contact with each other, the first step surface 2112 and the second step surface 232 are in contact with each other, and the first step surface 2113 and the second step surface 233 are in contact with each other.

[0061] See also Figure 1 and Figure 2 The insulating component 100 is provided with a plurality of connection bars 200, and the plurality of connection bars 200 are distributed on both sides of the collection harness 300. Among them, two connection bars 200 located at the ends are used to connect with other battery modules or output externally, and the two connection bars 200 are provided with connection ears 250, and the connection ears 250 are used to connect external leads to achieve communication connection with other battery modules.

[0062] See also Figure 2 , Figure 8 as well as Fig. 9 A limiting groove 240 is provided on the connection row 200 having a connection ear 250. Correspondingly, a clamping protrusion 212 is provided on the side wall of the connection row mounting groove 2 in which the connection row 200 is clamped. The clamping protrusion 212 is engaged with the above-mentioned limiting groove 240 to further improve the installation stability of the connection row 200.

[0063] See also Figure 4 and Figure 5 At least one fixing column 4 is provided on the bottom wall of the connecting row main groove 21. Figure 7 A fixing hole 260 is opened on the first plate body 210 of the connecting bar 200, and the fixing column 4 is penetrated into the fixing hole 260 of the first plate body 210, so as to further improve the installation firmness of the connecting bar 200 and prevent the connecting bar 200 from moving after installation.

[0064] In some embodiments, the fixing column 4 is a hot rivet column. After the fixing column 4 passes through the fixing hole 260, the head of the fixing column 4 is hot-melted to form a hot rivet head that stops the connecting row 200, thereby preventing the connecting row 200 from moving along its own thickness direction to disengage from the connecting row mounting groove 2.

[0065] See also Figure 4 and Figure 5 The fixed column 4 is provided with at least three ( Figure 4 and Figure 5 At least three fixing columns 4 are arranged in a triangular distribution, which helps to improve the fixing stability of the connecting bar 200. At the same time, the three fixing columns 4 arranged in a triangular distribution form a fool-proof design, which can prevent the connecting bar 200 from being installed in the wrong orientation.

[0066] Alternatively, see Figure 8 and Fig. 9 Two fixing holes 260 are arranged on the first plate body 210 of the connecting row 200 with the connecting ears 250, and two fixing columns 4 are arranged on the bottom wall of the corresponding connecting row main groove 21. The two fixing columns 4 are plugged into the two fixing holes 260 one by one, and the two fixing columns 4 are arranged diagonally relative to the first plate body 210. While ensuring that the connecting row 200 is firmly fixed, the number of fixing columns 4 can be reduced as much as possible.

[0067] In other embodiments, under the premise of satisfying the fixing firmness of the connection row 200 , the number of fixing columns 4 can be set as needed, and the number and distribution of the fixing columns 4 are not limited here.

[0068] In some embodiments, see Figure 3 , Figure 4 as well as Figure 5 , the card slot 22 extends from the connecting row main slot 21 to the wiring harness groove 3, accordingly, see Figure 7 The second plate body 220 extends an extension section relative to the side wall of the first plate body 210, so that the second plate body 220 of the connecting row 200 extends to the inside of the wiring harness groove 3 after installation, so as to be as close to the collection harness 300 as possible, ensuring that the second plate body 220 and the voltage collection bar 310 can fully contact each other, making laser welding of the second plate body 220 and the voltage collection bar 310 more convenient and increasing the flow area.

[0069] join Figure 2 , Figure 3 as well as Fig.10 A temperature collection component groove 5 is recessed on the insulating component 100, and the temperature collection component groove 5 is configured to engage with the temperature collection component 400 to fix the installation position of the temperature collection component 400 on the insulating component 100, to prevent the temperature collection component 400 from being pulled by the collection harness 300 and moving, resulting in failure of the temperature collection point between the temperature collection component 400 and the battery, thereby ensuring the temperature collection effect.

[0070] In some embodiments, the temperature collection component groove 5 is recessed on the mounting portion 1, and the temperature collection component 400 includes a mounting bracket 410 and a temperature sensing module 420 disposed on the mounting bracket 410. The temperature collection component groove 5 is used to engage the mounting bracket 410, and the temperature sensing module 420 is mounted on the mounting bracket 410, and the temperature sensing module 420 is connected to the collection harness 300 for communication, such as by a harness connection or a welding connection, to achieve temperature signal collection. The mounting bracket 410 is clamped in the temperature collection component groove 5, and the temperature sensing module 420 can be exposed while ensuring that the temperature collection component 400 is firmly installed, so as to be connected to the collection harness 300.

[0071] See also Figure 3 A temperature sampling hole 6 is provided through the bottom wall of the groove 5 of the temperature sampling component. At the same time, a through hole is also provided on the mounting bracket 410. The temperature sensing module 420, the through hole, the temperature sampling hole 6 and the temperature sampling point on the battery cell are arranged opposite to each other. Thermal conductive structural glue is poured into the through hole and the temperature sampling hole 6, so that the temperature sensing module 420 can contact the temperature sampling point on the battery cell through the thermal conductive structural glue, thereby realizing accurate temperature sampling of the battery cell.

[0072] Exemplarily, the temperature sensing module 420 is a temperature sensor, which can accurately collect temperature and is easy to connect with the temperature collection harness 300 .

[0073] See also Figure 3 and Fig.11 , multiple connecting row main grooves 21 are arranged on both sides of the harness groove 3, and the multiple connecting row main grooves 21 are installed one by one with the first plate bodies 210 of the multiple connecting rows 200, ensuring that each connecting row 200 can be well fixed. The multiple connecting row main grooves 21 on both sides of the harness groove 3 are staggered, avoiding the existence of too weak parts in the width direction of the insulating component 100, which is conducive to improving the overall strength of the insulating component 100 and making the strength distribution of the entire insulating component 100 more balanced.

[0074] In some embodiments, the insulating component 100 is integrally formed by vacuum molding, such as Fig.12 FIG. 1 is a schematic diagram of the back of the insulating component 100 after blister molding. The insulating component 100 is integrally molded by the blister molding process, which makes processing and manufacturing easier, low-cost, and convenient for mass production. For example, the insulating component 100 is made of PC material, which has high strength to avoid excessively weak strength after blister molding.

[0075] In other embodiments, the above-mentioned connection row main groove 21, the card groove 22, the wiring harness groove 3 and the temperature collection component groove 5 can also be formed by a later slotting process.

[0076] See also Fig.13In some embodiments, the thickness D of the insulating component 100 is greater than or equal to 4 mm and less than or equal to 15 mm.
