[0044] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific implementation methods.

For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0046] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0047] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0048] In the prior art, the high-voltage series-parallel connection of each battery in the battery module is usually achieved through the CCS component (Cells Contact System, integrated busbar), and the temperature and voltage of each battery are collected through the CCS component to monitor the working status of the battery in real time. In addition, it is necessary to set a connecting copper busbar on the battery module to realize the current transmission of the battery module during the charging and discharging process, and it is also necessary to set a communication harness on the battery module to communicate with the collection equipment outside the battery module to realize signal transmission. The above setting requires setting CCS components, connecting copper buses and communication harnesses on the battery module respectively, which not only reduces the production rhythm, but also reduces the assembly efficiency and processing efficiency.

[0049] In order to solve the above problems, Figure 1As shown, this embodiment provides an integrated connection plate, which includes a CCS component 1, a connecting copper busbar 2, and a communication harness 3, wherein the CCS component 1 includes an insulating bracket 11 and a plurality of connecting aluminum bars 12, wherein the plurality of connecting aluminum bars 12 are spaced apart on the insulating bracket 11, and the connecting aluminum bars 12 are used to electrically connect to the poles of the corresponding batteries in the battery module, the connecting copper bars 2 are integrated on the insulating bracket 11, and the communication harness 3 is integrated on the insulating bracket 11. The integrated connection plate provided in this embodiment improves the space utilization on the insulating bracket 11 and the integration of the integrated connection plate by integrating the connecting copper busbar 2 and the communication harness 3 on the insulating bracket 11 in the CCS component 1, and also facilitates the integrated incoming materials of the CCS component 1, the connecting copper busbar 2, and the communication harness 3, thereby improving the production takt of the integrated connection plate and the assembly efficiency and processing efficiency of the entire integrated connection plate.

[0050] Optionally, in this embodiment, the insulating bracket 11 is a plastic bracket to facilitate the production and processing of the insulating bracket 11 and ensure the electrical insulation performance of the insulating bracket 11. Optionally, in this embodiment, the multiple connecting aluminum bars 12 in the CCS assembly 1 realize the series connection between the individual batteries in the battery module, playing a role in overcurrent. Optionally, in this embodiment, among the multiple connecting aluminum bars 12, two of the connecting aluminum bars 12 are output aluminum bars to realize the output of current, and the remaining connecting aluminum bars 12 are series aluminum bars to realize the series connection between the individual batteries in the battery module. Optionally, in this embodiment, the connecting copper bars 2 realize the current transmission of the battery module during the charging and discharging process. Three connecting copper bars 2 are integrated on the insulating bracket 11, two of which are used for current transmission during the discharge process, and one of which is used for current transmission during the charging process. The connecting copper bars 2 that are used for current transmission during the charging process are used to connect to the total positive and total negative electricity of the battery module, and the connecting copper bars 2 that are used for current transmission during the discharge process are electrically connected to the BDU (Battery Drive Unit). Optionally, in this embodiment, the communication harness 3 is used to electrically connect to devices outside the battery module, such as an acquisition device or a motor.

[0051] In this embodiment, if Figures 2 to 4As shown, the insulating bracket 11 is provided with a plurality of spaced-apart accommodating grooves 112 for accommodating corresponding connecting aluminum bars 12. The grooves 112 are larger than the connecting aluminum bars 12, and a displacement space is formed between the inner sidewalls 1122 of the grooves 112 and the outer sidewalls of the connecting aluminum bars 12. This arrangement ensures that when the battery expands and pulls the connecting aluminum bars 12 to move, the grooves 112 provide corresponding displacement space for the connecting aluminum bars 12, thereby adapting to the displacement of the connecting aluminum bars 12. Optionally, in this embodiment, the grooves 112 are contoured grooves, with the dimension of the grooves 112 along the length of the insulating bracket 11 being slightly larger than the dimension of the connecting aluminum bars 12 along the length of the insulating bracket 11. This provides a certain displacement space for the connecting aluminum bars 12 along the length of the insulating bracket 11 to accommodate battery expansion. The dimension of the grooves 112 along the width of the insulating bracket 11 is adapted to the dimension of the connecting aluminum bars 12 along the width of the insulating bracket 11. In addition, by accommodating the connecting aluminum bars 12 in the corresponding accommodating grooves 112, the spacing between each connecting aluminum bar 12 is ensured, the positioning installation of the connecting aluminum bar 12 is achieved, and the electrical clearance and creepage distance between the connecting aluminum bars 12 and the connecting aluminum bars 12 and between the connecting aluminum bars 12 and the batteries are ensured.

[0052] Optionally, in this embodiment, if Figure 3 and Figure 4 As shown, the integrated connection plate also includes a fixing clip 4, which is provided on the insulating bracket 11 and abuts against the upper end surface of the connecting aluminum bar 12 in the accommodating groove 112. By providing the fixing clip 4, the connecting aluminum bar 12 is pressed and fixed in the corresponding accommodating groove 112. It should be noted that when the battery expands and pulls the connecting aluminum bar 12 to move, the connecting aluminum bar 12 can move relative to the fixing clip 4 under the action of the expansion force. Optionally, in this embodiment, each accommodating groove 112 is correspondingly provided with two fixing clips 4, and the two fixing clips 4 are arranged at intervals along the width direction of the insulating bracket 11. The two fixing clips 4 jointly press the connecting aluminum bar 12 into the corresponding accommodating groove 112, thereby improving the reliability of the fixing of the connecting aluminum bar 12. It should be noted that in this embodiment, the insulating bracket 11 and the fixing clip 4 are formed by integral injection molding, which not only ensures the structural strength of the insulating bracket 11 and the fixing clip 4, but also facilitates processing.

[0053] In this embodiment, if Figure 3 and Figure 5As shown, the integrated connecting plate also includes a fixing column 9, which is arranged on the bottom wall 1121 of the accommodating groove 112. A positioning hole 121 is provided on the connecting aluminum bar 12, and the fixing column 9 is inserted into the positioning hole 121. By providing the fixing column 9, the positioning installation of the connecting aluminum bar 12 in the corresponding accommodating groove 112 is achieved. Optionally, in this embodiment, the positioning hole 121 is a long waist hole, so as to adapt to the displacement of the connecting aluminum bar 12 due to the expansion of the battery. Optionally, in this embodiment, the fixing column 9 can be a hot riveting column, so as to achieve the fixation of the connecting aluminum bar 12. Optionally, in this embodiment, the series aluminum bar is fixed by a fixing buckle 4, and the output aluminum bar is fixed by a hot riveting column (i.e., the fixing column 9). Optionally, in this embodiment, the insulating bracket 11 and the fixing column 9 are formed by integral injection molding, which not only ensures the structural strength of the insulating bracket 11 and the fixing column 9, but also makes processing convenient.

[0054] In this embodiment, if Figure 3 As shown, an avoidance hole 1123 is opened on the bottom wall 1121 of the accommodating groove 112, and the integrated connecting plate also includes a supporting spring 5, which is arranged on the hole wall of the avoidance hole 1123. The supporting spring 5 is used to elastically support the connecting aluminum bar 12 located in the accommodating groove 112. The above arrangement enables the insulating bracket 11 to achieve an insulating bearing effect on the connecting aluminum bar 12, and when the connecting aluminum bar 12 is not welded to the battery pole, the connecting aluminum bar 12 is pushed up by the support spring 5, which can prevent the connecting aluminum bar 12 from contacting the corresponding battery pole. When it is necessary to weld the connecting aluminum bar 12 to the corresponding battery pole through the avoidance hole 1123, the support spring 5 is compressed. When each connecting aluminum bar 12 is welded to the corresponding battery pole one by one, the unwelded connecting aluminum bar 12 and the corresponding battery pole are in a power-off state, thereby avoiding sparks caused by an incorrect welding power-on sequence, which leads to the release of huge heat, damage to the charger and battery, and even the risk of fire, making it safer. Optionally, in this embodiment, one end of the support spring 5 is connected to the wall of the avoidance hole 1123, and the other end of the support spring 5 is suspended. In a natural state, the support spring 5 is bent relative to the bottom wall 1121 of the accommodating groove 112 toward the connecting aluminum bar 12, thereby ensuring the elasticity of the support spring 5 and also ensuring that the connecting aluminum bar 12 is lifted up by the action of the support spring 5, so that in the natural state, there is a gap between the connecting aluminum bar 12 and the bottom wall 1121. Optionally, in this embodiment, the insulating bracket 11 and the support spring 5 are formed by integral injection molding, which not only ensures the structural strength of the insulating bracket 11 and the support spring 5, but also facilitates processing.

[0055] In this embodiment, if Figure 4As shown, the insulating bracket 11 is provided with a tie hole 113, and the integrated connecting plate also includes a tie 6. The tie 6 passes through the tie hole 113 and is wrapped around the outer periphery of the connecting copper busbar 2 or the communication wiring harness 3 to bind and secure the connecting copper busbar 2 or the communication wiring harness 3 to the insulating bracket 11. Specifically, in this embodiment, the connecting copper busbar 2 and the communication wiring harness 3 are both bound and secured to the insulating bracket 11 via corresponding tie holes 6. Compared to the traditional method of securing the connecting copper busbar 2 and the communication wiring harness 3 using a fir tree head and tie 6, this method of securing the connecting copper busbar 2 and the communication wiring harness 3 simplifies the structure, greatly reduces the fixing cost, and improves the space utilization on the insulating bracket 11. In addition, by using the tie 6 to secure the connecting copper busbar 2 and the communication wiring harness 3 to the insulating bracket 11, the movement of the connecting copper busbar 2 and the communication wiring harness 3 during vibration is prevented, thereby ensuring electrical safety. In addition, the tie 6 securing the connecting copper busbar 2 and the communication wiring harness 3 can share the tie hole 113, which not only saves space but also further reduces costs. Optionally, in this embodiment, the connecting copper busbar 2 and the fixed communication wiring harness 3 both extend along the length direction of the insulating bracket 11, and the connecting copper busbar 2 is provided with a plurality of cable ties 6 at intervals along its extension direction to ensure the stability of the binding and fixation of the connecting copper busbar 2. Optionally, the communication wiring harness 3 is provided with a plurality of cable ties 6 at intervals along its extension direction to ensure the stability of the binding and fixation of the communication wiring harness 3.

[0056] Optionally, in the present embodiment, the outer peripheral side of the communication harness 3 is wrapped with an insulating protective tape. The above arrangement avoids the wear of the cable tie 6 on the communication harness 3, and effectively improves the insulation protection performance and wear resistance of the communication harness 3. Optionally, the insulating protective tape wrapped around the outer peripheral side of the communication harness 3 may be a cloth-based tape. Optionally, in the present embodiment, the outer peripheral side of the connecting copper bus 2 is wrapped with an insulating protective tape. The above arrangement avoids the wear of the cable tie 6 on the connecting copper bus 2, and effectively improves the insulation protection performance and wear resistance of the outer peripheral side of the connecting copper bus 2. Optionally, the insulating protective tape wrapped around the outer peripheral side of the connecting copper bus 2 may be a cloth-based tape.

[0057] In this embodiment, if Figure 4As shown, the integrated connection plate also includes a plurality of positioning platforms 7 arranged at intervals, and the positioning platforms 7 are arranged on the insulating bracket 11. The two positioning platforms 7 arranged adjacent to each other along the width direction of the insulating bracket 11 form a limiting space, and the limiting space accommodates the connecting copper bus 2. The above-mentioned arrangement realizes the limiting of the connecting copper bus 2 on the insulating bracket 11 along the width direction of the insulating bracket 11 during the installation and fixation process, and the positioning platform 7 has the advantage of a simple structure. Optionally, in this embodiment, the two positioning platforms 7 arranged adjacent to each other along the width direction of the insulating bracket 11 form a positioning platform group, and a plurality of positioning platform groups are arranged at intervals on the insulating bracket 11 along the extension direction of the connecting copper bus 2, thereby improving the reliability of positioning the connecting copper bus 2. Optionally, in this embodiment, the insulating bracket 11 and the positioning platform 7 are formed by integral injection molding, which not only ensures the structural strength of the insulating bracket 11 and the positioning platform 7, but also makes processing convenient.

[0058] Optionally, in this embodiment, the cable tie through-hole 113 is adjacent to the positioning platform 7, and the cable tie 6 is passed through the cable tie through-hole 113 and wrapped around the outer periphery of the connecting copper busbar 2 and the positioning platform 7 to bind and secure the connecting copper busbar 2 to the insulating support 11; or, the cable tie 6 is passed through the cable tie through-hole 113 and wrapped around the outer periphery of the communication wiring harness 3 and the positioning platform 7 to bind and secure the communication wiring harness 3 to the insulating support 11. The above arrangement effectively reduces the length of the cable tie 6 used for binding and securing, and makes the arrangement of the connecting copper busbar 2 and the communication wiring harness 3 more compact and reasonable, thereby more fully and reasonably utilizing the space on the insulating support 11.

[0059] In this embodiment, if Figure 1 、 Figure 5 and Figure 6 As shown, the CCS assembly 1 also includes a flexible circuit board 13 and a CSC slave board 14 (Combination Data Plate). The flexible circuit board 13 is mounted on the insulating bracket 11 and electrically connected to the connecting aluminum bar 12. The CSC slave board 14 is also mounted on the insulating bracket 11 and electrically connected to the flexible circuit board 13 by welding. By directly welding the CSC slave board 14 and the flexible circuit board 13, compared to the traditional connection between the CSC slave board 14 and the flexible circuit board 13 via a connector and wiring harness, not only does it reduce connection costs but also improves space utilization on the insulating bracket 11. Optionally, in this embodiment, the flexible circuit board 13 is located at the bottom of the communication harness 3.

[0060] Optionally, in this embodiment, if Figure 5As shown, the flexible circuit board 13 includes a main body 131 and a bent portion 132, which are connected to each other. The main body 131 is electrically connected to the connecting aluminum bar 12. The bent portion 132 is bent relative to the main body 131 in a direction away from the connecting aluminum bar 12 and is welded to the CSC slave board 14. A gap exists between the connecting aluminum bar 12 and the main body 131 along the bending direction of the bent portion 132. This arrangement makes the structural layout of the various components integrated and mounted on the insulating bracket 11 more compact and reasonable, thereby fully utilizing the installation space on the insulating bracket 11. Furthermore, it ensures electrical and mechanical isolation between the CSC slave board 14 and the connecting aluminum bar 12, and frees up space for the main body 131 on the side of the CSC slave board 14 near the connecting aluminum bar 12, thereby reducing the risk of damage to the CSC slave board 14 during transportation, assembly, and vibration, which could lead to abnormal data acquisition. For example, the bent portion 132 may be bent upward relative to the main body 131 , and a gap may be provided between the connecting aluminum bar 12 , the main body 131 , and the CSC slave plate 14 in the vertical direction.

[0061] Specifically, in this embodiment, if Figure 5 As shown, the integrated connection plate also includes a support assembly 8, which includes a connected support platform 81 and a positioning column 82. The support platform 81 is arranged on the insulating bracket 11, and the support platform 81 is used to support the CSC slave plate 14. The CSC slave plate 14 is provided with a plug hole 141, and the positioning column 82 is plugged and fixed in the plug hole 141. The above arrangement can lift the CSC slave plate 14 so that there is a certain distance between the CSC slave plate 14 and the connecting aluminum bar 12 along the bending direction of the bending portion 132 (for example, it can be the up and down direction). Optionally, in this embodiment, the positioning column 82 can be a hot riveting column, so as to achieve the fixation of the CSC slave plate 14. Optionally, in this embodiment, the insulating bracket 11 and the support assembly 8 are formed by integral injection molding, which not only ensures the structural strength of the insulating bracket 11 and the support assembly 8, but also makes processing convenient.

[0062] Optionally, in this embodiment, if Figure 6 As shown, the CCS assembly 1 further includes a connecting nickel sheet 15, and the connecting aluminum bar 12 is electrically connected to the flexible circuit board 13 via the connecting nickel sheet 15. The connecting nickel sheet 15 has the advantages of excellent electrical conductivity, good mechanical strength, and corrosion resistance.

[0063] Optionally, in this embodiment, if Figure 2 and Figure 7As shown, the insulating bracket 11 includes at least two bracket bodies 111, which are plug-connected along the length of the insulating bracket 11. By designing the insulating bracket 11 as at least two bracket bodies 111 that are plug-connected along the length of the insulating bracket 11, the length of a single bracket body 111 is effectively shortened, facilitating injection molding of a single bracket body 111, reducing mold opening costs for the bracket body 111, shortening the mold opening cycle for the bracket body 111, improving production efficiency, and reducing processing costs. In addition, the plug-in connection between two adjacent bracket bodies 111 makes the structure simple and easy to assemble and disassemble.

[0064] Optionally, in this embodiment, the insulating bracket 11 includes two bracket bodies 111. In other embodiments, the number of bracket bodies 111 can be adjusted according to the length requirements of the insulating bracket 11. Optionally, in this embodiment, the length dimension of the insulating bracket 11 can exceed 1400 mm, and the length dimension of the insulating bracket 11 can reach 1767 mm, which can meet the demand for a large length of the insulating bracket 11. It should be noted that, in this embodiment, the fixing clip 4, the supporting spring 5, the positioning platform 7, the fixing column 9 and the support assembly 8 are all formed by integral injection molding with the bracket body 111.

[0065] Optionally, in this embodiment, if Figure 7 and Figure 8 As shown, in two adjacent bracket bodies 111 connected in a plug-in manner, the end of one bracket body 111 includes a first latch 1111, and the end of the other bracket body 111 includes a second latch 1114. The first latch 1111 and the second latch 1114 are engaged and fixed. The plug-in connection between the two adjacent bracket bodies 111 is achieved by the engagement and fixation of the first latch 1111 and the second latch 1114, making the structure simple and easy to assemble and disassemble.

[0066] Optionally, in this embodiment, if Figure 7 and Figure 8 As shown, of the two adjacent bracket bodies 111 connected by plugging, the end of one bracket body 111 includes a locking protrusion 1112, and the end of the other bracket body 111 is provided with a locking groove 1115, and the locking protrusion 1112 is fixedly engaged in the locking groove 1115.
