[0043] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] In existing technologies, high-voltage series and parallel connections of individual cells within a battery module are typically achieved using a CCS (Cells Contact System, integrated busbar) module. The CCS module also collects the temperature and voltage of each cell to monitor its operating status in real time. Furthermore, connecting copper busbars are required on the battery module to facilitate current transfer during charging and discharging. Communication harnesses are also needed to connect the battery module to external data acquisition devices for signal transmission. This setup, requiring the separate installation of the CCS module, connecting copper busbars, and communication harnesses on the battery module, not only reduces production cycle time but also lowers assembly and processing efficiency.

[0048] To solve the above problems, such as Figures 1-4As shown, this embodiment provides an integrated connection board, which includes a CCS component 1, a connecting copper busbar 2, and a communication harness 3. The CCS component 1 includes an insulating bracket 11 and multiple connecting aluminum busbars 12. The insulating bracket 11 has multiple spaced-apart receiving grooves 112, and the multiple connecting aluminum busbars 12 are housed in corresponding receiving grooves 112. The connecting aluminum busbars 12 are used for electrical connection with the terminals of corresponding batteries in the battery module. The connecting copper busbar 2 and the communication harness 3 are integrated into the insulating bracket 11. The integrated connection board provided in this embodiment improves the space utilization of the insulating bracket 11 and increases the integration degree of the integrated connection board by integrating the connecting copper busbar 2 and the communication harness 3 onto the insulating bracket 11 in the CCS component 1. It also facilitates the integrated feeding of the CCS component 1, connecting copper busbar 2, and communication harness 3, increasing the production cycle time of the integrated connection board and improving the overall assembly and processing efficiency of the integrated connection board. In addition, by accommodating the connecting aluminum busbar 12 in the corresponding accommodating groove 112, the spacing between each connecting aluminum busbar 12 is ensured, the positioning and installation of the connecting aluminum busbar 12 are realized, and the electrical clearance and creepage distance between connecting aluminum busbar 12 and between connecting aluminum busbar 12 and battery are guaranteed.

[0049] Optionally, in this embodiment, the insulating bracket 11 is a plastic bracket to facilitate its production and processing, and also to ensure its electrical insulation performance. Optionally, in this embodiment, the multiple connecting aluminum busbars 12 in the CCS component 1 realize the series connection between the batteries in the battery module, serving as a current-carrying function. Optionally, in this embodiment, among the multiple connecting aluminum busbars 12, two are output aluminum busbars to realize current output, and the remaining connecting aluminum busbars 12 are series aluminum busbars to realize the series connection between the batteries in the battery module. Optionally, in this embodiment, the connecting copper busbars 2 realize the current transfer of the battery module during charging and discharging. Three connecting copper busbars 2 are integrated on the insulating bracket 11, of which two connect copper busbars 2 are used for current transfer during the discharging process, and one connect copper busbar 2 is used for current transfer during the charging process. The connecting copper busbar 2 used for current transfer during the charging process is used for total positive and total negative electrical connection with the battery module, and the connecting copper busbar 2 used for current transfer during the discharging process is 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 a data acquisition device or a motor.

[0050] In this embodiment, as Figures 2-4As shown, the size of the receiving groove 112 is larger than the size of the connecting aluminum busbar 12, and a displacement space is formed between the inner sidewall 1122 of the receiving groove 112 and the outer sidewall of the connecting aluminum busbar 12. This arrangement ensures that when the battery expands and pulls the connecting aluminum busbar 12, the receiving groove 112 can provide a corresponding displacement space for the connecting aluminum busbar 12, thereby adapting to the displacement of the connecting aluminum busbar 12. Optionally, in this embodiment, the receiving groove 112 is a contoured groove, and the size of the receiving groove 112 along the length direction of the insulating support 11 is slightly larger than the size of the connecting aluminum busbar 12 along the length direction of the insulating support 11, so that the connecting aluminum busbar 12 has a certain displacement space along the length direction of the insulating support 11 to adapt to the expansion of the battery. The size of the receiving groove 112 along the width direction of the insulating support 11 is adapted to the size of the connecting aluminum busbar 12 along the width direction of the insulating support 11.

[0051] Optionally, in this embodiment, as Figure 3 and Figure 4 As shown, the integrated connecting plate also includes a fixing buckle 4, which is disposed on the insulating bracket 11 and abuts against the upper end face of the connecting aluminum busbar 12 in the receiving groove 112. By setting the fixing buckle 4, the connecting aluminum busbar 12 is pressed and fixed in the corresponding receiving groove 112. It should be noted that when the battery expands and pulls the connecting aluminum busbar 12 to move, the connecting aluminum busbar 12 can move relative to the fixing buckle 4 under the action of the expansion force. Optionally, in this embodiment, each receiving groove 112 is provided with two fixing buckles 4, which are arranged at intervals along the width direction of the insulating bracket 11. The two fixing buckles 4 together press and fix the connecting aluminum busbar 12 in the corresponding receiving groove 112, improving the reliability of fixing the connecting aluminum busbar 12. It should be noted that in this embodiment, the insulating bracket 11 and the fixing buckle 4 are integrally injection molded, which not only ensures the structural strength of the insulating bracket 11 and the fixing buckle 4, but also makes the processing convenient.

[0052] In this embodiment, as Figure 3 and Figure 5As shown, the integrated connecting plate also includes a fixing post 9, which is disposed on the bottom wall 1121 of the receiving groove 112. The connecting aluminum busbar 12 is provided with a positioning hole 121, and the fixing post 9 is inserted into the positioning hole 121. By setting the fixing post 9, the connecting aluminum busbar 12 is positioned and installed in the corresponding receiving groove 112. Optionally, in this embodiment, the positioning hole 121 is an elongated hole to accommodate the displacement of the connecting aluminum busbar 12 due to battery expansion. Optionally, in this embodiment, the fixing post 9 can be a hot-riveted post to fix the connecting aluminum busbar 12. Optionally, in this embodiment, the series aluminum busbars are fixed by the fixing buckle 4, and the output aluminum busbars are fixed by the hot-riveted post (i.e., the fixing post 9). Optionally, in this embodiment, the insulating bracket 11 and the fixing post 9 are integrally injection molded, which not only ensures the structural strength of the insulating bracket 11 and the fixing post 9 but also facilitates processing.

[0053] In this embodiment, as Figure 3 As shown, a clearance hole 1123 is provided on the bottom wall 1121 of the receiving groove 112. The integrated connecting plate also includes a support spring 5, which is disposed on the hole wall of the clearance hole 1123. The support spring 5 is used to elastically support the connecting aluminum strip 12 located in the receiving groove 112. The above configuration enables the insulating bracket 11 to achieve the insulating bearing effect of the connecting aluminum busbar 12. When the connecting aluminum busbar 12 is not welded to the battery terminal, the connecting aluminum busbar 12 is lifted by the supporting spring 5, which can prevent the connecting aluminum busbar 12 from contacting the corresponding battery terminal. When it is necessary to weld the connecting aluminum busbar 12 to the corresponding battery terminal through the clearance hole 1123, the supporting spring 5 is compressed. When each connecting aluminum busbar 12 is welded to the corresponding battery terminal in sequence, the unwelded connecting aluminum busbar 12 and the corresponding battery terminal are in a de-energized state, thereby avoiding arcing caused by incorrect welding power-on sequence, which would release huge heat, damage the charger and battery, and even pose a fire risk, making it safer. Optionally, in this embodiment, one end of the supporting spring 5 is connected to the wall of the clearance hole 1123, and the other end of the supporting spring 5 is suspended. In its natural state, the supporting spring 5 is bent relative to the bottom wall 1121 of the receiving groove 112 towards the connecting aluminum busbar 12, ensuring the elasticity of the supporting spring 5 and ensuring that the connecting aluminum busbar 12 is lifted by the supporting spring 5, so that there is a gap between the connecting aluminum busbar 12 and the bottom wall 1121 in its natural state. Optionally, in this embodiment, the insulating bracket 11 and the supporting spring 5 are integrally injection molded, which not only ensures the structural strength of the insulating bracket 11 and the supporting spring 5, but also makes processing convenient.

[0054] In this embodiment, as Figure 4As shown, the insulating bracket 11 has cable tie holes 113. The integrated connecting plate also includes cable ties 6, which pass through the cable tie holes 113 and wrap around the outer periphery of the connecting copper busbar 2 or the communication harness 3 to secure the connecting copper busbar 2 or the communication harness 3 to the insulating bracket 11. Specifically, in this embodiment, both the connecting copper busbar 2 and the communication harness 3 are secured to the insulating bracket 11 by corresponding cable ties 6. Compared with the traditional method of securing the connecting copper busbar 2 and the communication harness 3 with cedar branches and cable ties 6, the above-mentioned method of installing and securing the connecting copper busbar 2 and the communication harness 3 simplifies the structure, greatly reduces the fixing cost, and improves the space utilization of the insulating bracket 11. In addition, by using cable ties 6 to secure the connecting copper busbar 2 and the communication harness 3 to the insulating bracket 11, movement of the connecting copper busbar 2 and the communication harness 3 during vibration is prevented, ensuring electrical safety. Furthermore, the cable ties 6 used to secure the connecting copper busbar 2 and the communication harness 3 can share the cable tie holes 113, which not only saves space but also further reduces costs. Optionally, in this embodiment, both the connecting copper busbar 2 and the fixed communication harness 3 extend along the length direction of the insulating bracket 11. The connecting copper busbar 2 is provided with multiple cable ties 6 at intervals along its extension direction to ensure the stability of the binding and fixing of the connecting copper busbar 2. Optionally, the communication harness 3 is provided with multiple cable ties 6 at intervals along its extension direction to ensure the stability of the binding and fixing of the communication harness 3.

[0055] Optionally, in this embodiment, the outer periphery of the communication harness 3 is wrapped with insulating protective tape. This arrangement prevents the cable ties 6 from causing wear to the communication harness 3, effectively improving the insulation and abrasion resistance of the communication harness 3. Optionally, the insulating protective tape wrapped around the outer periphery of the communication harness 3 can be cloth-based tape. Optionally, in this embodiment, the outer periphery of the connecting copper busbar 2 is wrapped with insulating protective tape. This arrangement prevents the cable ties 6 from causing wear to the connecting copper busbar 2, effectively improving the insulation and abrasion resistance of the outer periphery of the connecting copper busbar 2. Optionally, the insulating protective tape wrapped around the outer periphery of the connecting copper busbar 2 can be cloth-based tape.

[0056] In this embodiment, as Figure 4As shown, the integrated connecting plate also includes multiple spaced positioning platforms 7. The positioning platforms 7 are disposed on the insulating support 11. Two adjacent positioning platforms 7 arranged along the width direction of the insulating support 11 form a limiting space, in which the connecting copper busbar 2 is accommodated. This arrangement enables the connecting copper busbar 2 to be limited on the insulating support 11 along the width direction of the insulating support 11 during installation and fixing, and the positioning platforms 7 have the advantage of simple structure. Optionally, in this embodiment, two adjacent positioning platforms 7 arranged along the width direction of the insulating support 11 form a positioning platform group. Multiple positioning platform groups are spaced apart on the insulating support 11 along the extension direction of the connecting copper busbar 2, thereby improving the reliability of positioning the connecting copper busbar 2. Optionally, in this embodiment, the insulating support 11 and the positioning platforms 7 are integrally injection molded, which not only ensures the structural strength of the insulating support 11 and the positioning platforms 7 but also facilitates processing.

[0057] Optionally, in this embodiment, the cable tie through-hole 113 is adjacent to the positioning platform 7, and the cable tie 6 passes through the cable tie through-hole 113 and wraps around the outer periphery of the connecting copper busbar 2 and the positioning platform 7 to bind and fix the connecting copper busbar 2 to the insulating bracket 11; or, the cable tie 6 passes through the cable tie through-hole 113 and wraps around the outer periphery of the communication cable harness 3 and the positioning platform 7 to bind and fix the communication cable harness 3 to the insulating bracket 11. The above arrangement effectively reduces the length of the cable tie 6 for binding and fixing, and makes the arrangement of the connecting copper busbar 2 and the communication cable harness 3 more compact and reasonable, thereby making fuller and more reasonable use of the space on the insulating bracket 11.

[0058] In this embodiment, as 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 disposed on the insulating support 11 and is electrically connected to the connecting aluminum busbar 12. The CSC slave board 14 is disposed on the insulating support 11 and is electrically connected to the flexible circuit board 13 by soldering. By directly soldering the CSC slave board 14 to the flexible circuit board 13, compared to the traditional scheme of connecting the CSC slave board 14 and the flexible circuit board 13 through a connector and wire harness adapter, not only is the connection cost reduced, but the space utilization on the insulating support 11 is also improved. Optionally, in this embodiment, the flexible circuit board 13 is located at the bottom of the communication wire harness 3.

[0059] Optionally, in this embodiment, as Figure 5As shown, the flexible circuit board 13 includes a main body 131 and a bent portion 132 connected to each other. The main body 131 is electrically connected to the connecting aluminum busbar 12. The bent portion 132 is bent relative to the main body 131 in a direction away from the connecting aluminum busbar 12 and is electrically connected to the CSC slave board 14 by welding. The connecting aluminum busbar 12 and the main body 131 are spaced apart from the CSC slave board 14 along the bending direction of the bent portion 132. This arrangement makes the structural layout of the various devices integrated on the insulating bracket 11 more compact and reasonable, thereby making full use of the mounting space on the insulating bracket 11. Furthermore, it ensures electrical and mechanical isolation between the CSC slave board 14 and the connecting aluminum busbar 12, and provides space for the main body 131 of the CSC slave board 14 on the side closer to the connecting aluminum busbar 12, avoiding the risk of abnormal data acquisition due to damage to the CSC slave board 14 during transportation, assembly, and vibration. By way of example, the bent portion 132 may be bent upward relative to the main body portion 131, and the connecting aluminum busbar 12 and the main body portion 131 may be spaced apart from the CSC slave plate 14 in the vertical direction.

[0060] Specifically, in this embodiment, as Figure 5 As shown, the integrated connecting plate also includes a support assembly 8, which includes a support platform 81 and a positioning post 82 connected to each other. The support platform 81 is disposed on the insulating bracket 11 and is used to support the CSC slave plate 14. The CSC slave plate 14 is provided with a plug hole 141, and the positioning post 82 is plugged and fixed in the plug hole 141. The above arrangement can raise the CSC slave plate 14, so that there is a certain gap between the CSC slave plate 14 and the connecting aluminum busbar 12 along the bending direction of the bending portion 132 (exemplarily described, it can be the vertical direction). Optionally, in this embodiment, the positioning post 82 can be a hot-riveted post, thereby realizing the fixation of the CSC slave plate 14. Optionally, in this embodiment, the insulating bracket 11 and the support assembly 8 are integrally injection molded, which not only ensures the structural strength of the insulating bracket 11 and the support assembly 8, but also makes the processing convenient.

[0061] Optionally, in this embodiment, as Figure 6 As shown, the CCS assembly 1 also includes a connecting nickel strip 15, through which the connecting aluminum busbar 12 is electrically connected to the flexible circuit board 13. The connecting nickel strip 15 has the advantages of excellent conductivity, good mechanical strength, and corrosion resistance.

[0062] Optionally, in this embodiment, as Figure 2 and Figure 7As shown, the insulating bracket 11 includes at least two bracket bodies 111, which are plugged together along the length of the insulating bracket 11. By designing the insulating bracket 11 as at least two bracket bodies 111 plugged together 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 and shortening the mold opening cycle, improving production efficiency, and lowering processing costs. Furthermore, the plug-in connection between adjacent bracket bodies 111 simplifies the structure and facilitates assembly and disassembly.

[0063] 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 of the insulating bracket 11 can exceed 1400mm, and the length of the insulating bracket 11 can reach 1767mm, which can meet the requirements for large-length insulating brackets 11. It should be noted that in this embodiment, the fixing buckle 4, the supporting spring 5, the positioning platform 7, the fixing column 9, and the supporting assembly 8 are all integrally injection molded with the bracket body 111.

[0064] Optionally, in this embodiment, as Figure 7 and Figure 8 As shown, in the two adjacent bracket bodies 111 that are connected by a plug-in joint, one bracket body 111 has a first latch 1111 at one end, and the other bracket body 111 has a second latch 1114 at one end. The first latch 1111 and the second latch 1114 are engaged and fixed together. The plug-in connection between the two adjacent bracket bodies 111 is achieved by engaging and fixing the first latch 1111 and the second latch 1114, which makes the structure simple and facilitates disassembly and assembly.

[0065] Optionally, in this embodiment, as Figure 7 and Figure 8 As shown, in the two adjacent bracket bodies 111 that are connected by insertion, one bracket body 111 has a locking protrusion 1112 at its end, and the other bracket body 111 has a locking groove 1115 at its end. The locking protrusion 1112 is locked and fixed in the locking groove 1115. By setting the locking protrusion 1112 and the locking groove 1115 for locking connection, the stability and reliability of the insertion connection between the two adjacent bracket bodies 111 are further ensured.

[0066] Optionally, in this embodiment, as Figure 7 and Figure 8As shown, in the two adjacent bracket bodies 111 that are connected by insertion, one bracket body 111 has a groove 1116 at its end, and the other bracket body 111 has an insert 1113 at its end. The groove 1116 extends along the insertion direction of the two adjacent bracket bodies 111, and the insert 1113 is slidably inserted into the groove 1116. By providing sliding insertion strips 1113 and grooves 1116, a guiding function is provided for the insertion connection between two adjacent bracket bodies 111, ensuring the accuracy of the insertion connection between the two adjacent bracket bodies 111. Optionally, in this embodiment, among the two adjacent bracket bodies 111 connected by insertion, one bracket body 111 has multiple insertion strips 1113 spaced apart along the width direction of the insulating bracket 11 at its end, and a groove 1116 is formed between two adjacent insertion strips 1113.
