[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] See Figure 1 and Figure 5 This application provides a CCS bracket 100, which is applied to a CCS assembly (CellsContact System, integrated busbar). The CCS bracket 100 includes an isolation plate 110 and a wire clamping plate 120.

[0031] See Figure 1 and Figure 5The separator 110 serves as a support structure for the CCS module, supporting the various functional structures within it. It also separates these functional structures from the battery cells in the battery module, protecting the battery module. The separator 110 has a first mounting groove 111 extending along a first direction. The first mounting groove 111 is located on the side of the separator 110 opposite to the battery module. Multiple first mounting grooves 111 are provided on the separator 110, such as two, spaced apart in a direction perpendicular to the first direction. Furthermore, the separator 110 also has a second mounting groove 115 and an explosion-proof hole 116. The second mounting groove 115 is used to mount the busbar 300. The explosion-proof hole 116 corresponds to the explosion-proof valve of the battery module. The first mounting groove 111 is located between the second mounting groove 115 and the explosion-proof hole 116. The first mounting groove 111 is used to mount the wiring harness 200, which is electrically connected to the aluminum busbar.

[0032] See Figure 1 and Figure 5 A wire clamping plate 120 is disposed on the separator 110, located on the side of the separator 110 opposite to the battery module, and is fixedly connected to the separator 110. The wire clamping plate 120 extends along a second direction, with the first direction and the second direction forming a preset angle. For example, the first direction is the X-axis direction, and the second direction is the Y-axis direction. The wire clamping plate 120 is at least partially located above the first mounting groove 111, and along the thickness direction of the separator 110, the wire clamping plate 120 is spaced a certain distance from the bottom of the first mounting groove 111. The wire clamping plate 120 is used to fix the wire harness 200 within the first mounting groove 111.

[0033] In this embodiment, a first mounting groove 111 is provided on the isolation plate 110, and the wire harness 200 is installed in the first mounting groove 111. The wire clamping plate 120 and the bottom of the first mounting groove 111 form a clamping space to fix the wire harness 200 in the first mounting groove 111, thereby realizing the installation and fixation of the wire harness 200. The installation operation of the wire harness 200 is simple, the installation speed is fast, and the production efficiency is high.

[0034] In some embodiments, see Figure 1 and Figure 3 Multiple wire clamping plates 120 are spaced apart along a first direction. The first direction is the extension direction of the wire harness 200, and the multiple wire clamping plates 120 are spaced apart along this direction. The multiple wire clamping plates 120 fix different positions of the wire harness 200, ensuring that the wire harness 200 is fixed along its entire length, thus guaranteeing the stability of the wire harness 200 installation.

[0035] In some embodiments, the spacing between any adjacent pressure plates 120 is the same. Along the length of the wire harness 200, the wire harness 200 is subjected to uniform force, ensuring the stability of the wire harness 200 installation.

[0036] In some embodiments, see Figure 3 The distance between any two adjacent pressure plates 120 is S, where 50mm ≤ S ≤ 80mm. The value of S can be 50mm, 55mm, 58mm, 61mm, 65mm, 69mm, 72mm, 78mm, 80mm or other unlisted values.

[0037] In this embodiment, if the distance between any two adjacent wire clamping plates 120 is less than 50mm, the number of wire clamping plates 120 along the length of the wire harness 200 is relatively large, which is not conducive to the installation of the wire harness 200. If the distance between any two adjacent wire clamping plates 120 is greater than 80mm, the distance between adjacent wire clamping plates 120 along the length of the wire harness 200 is relatively large, and the wire harness 200 is prone to misalignment and bulging, which is not conducive to the installation and fixation of the wire harness 200.

[0038] In some embodiments, see Figure 2 The first mounting groove 111 has a first sidewall 112 and a second sidewall 113 that are arranged opposite to each other, and both the first sidewall 112 and the second sidewall 113 are provided with pressure plates 120.

[0039] The pressure plate 120 is a rectangular or elongated elastic plate structure. One end of the pressure plate 120 disposed on the first sidewall 112 is fixedly connected to the first sidewall 112, and the other end extends to the second sidewall 113. One end of the pressure plate 120 disposed on the second sidewall 113 is fixedly connected to the second sidewall 113, and the other end extends to the first sidewall 112. Along the length direction of the first mounting groove 111, the spacing between adjacent pressure plates 120 on the first sidewall 112 is the same, and the spacing between adjacent pressure plates 120 on the second sidewall 113 is the same. The width of the pressure plate 120 on the first sidewall 112 is the same as the width of the pressure plate 120 on the second sidewall 113. The thickness of the pressure plate 120 is 0.5 mm.

[0040] In this embodiment of the application, pressure plates 120 are respectively provided on the first sidewall 112 and the second sidewall 113 to facilitate the processing of pressure plates 120.

[0041] In some embodiments, the wire clamping plates 120 on the first sidewall 112 and the wire clamping plates 120 on the second sidewall 113 are staggered. It is understood that the holding force at the free end of the wire clamping plate 120 is less than the holding force at the fixed end. By staggering the wire clamping plates 120 on the first sidewall 112 and the wire clamping plates 120 on the second sidewall 113, the wire harness 200 is staggered and fixed along its length, ensuring the stability of the wire harness 200 installation.

[0042] In some embodiments, see Figure 2The first mounting groove 111 has a first sidewall 112 and a second sidewall 113 disposed opposite to each other. The first sidewall 112 and the second sidewall 113 extend along a first direction. The wire clamping plate 120 includes a first plate body 121 and a second plate body 122. The first plate body 121 is fixedly connected to the first sidewall 112, and the second plate body 122 is fixedly connected to the second sidewall 113. One end of the first plate body 121 facing away from the first sidewall 112 is disposed opposite to one end of the second plate body 122 facing away from the second sidewall 113. The first plate body 121 and the second plate body 122 extend along a second direction. The free ends of the first plate body 121 and the free ends of the second plate body 122 are abutted or spaced apart by a small distance. The first plate body 121 and the second plate body 122 are rectangular or elongated elastic plate structures.

[0043] In this embodiment, the wire clamping plate 120 is provided with a first plate 121 and a second plate 122 disposed opposite to each other. During the installation of the wire harness 200, the deformation of the first plate 121 and the second plate 122 is small, which reduces the probability of damage to the first plate 121 and the second plate 122 due to large deformation caused by the lengthening process of the first plate 121 and the second plate 122.

[0044] In some embodiments, see Figure 2 The first plate 121 and the second plate 122 are inclined, and the end of the first plate 121 and the second plate 122 that are close to each other is closer to the bottom of the first mounting groove 111 than the other end.

[0045] In this embodiment of the application, when the wire harness 200 is installed in the first mounting groove 111, the first plate 121 and the second plate 122 are tilted. The wire harness 200 presses against the first plate 121 and the second plate 122. Under the action of the elastic restoring force of the first plate 121 and the second plate 122, the wire harness 200 is always pressed against the first plate 121 and the second plate 122, which improves the stability of the installation of the wire harness 200.

[0046] In some embodiments, see Figure 2 The included angle α formed between the first plate 121 and the second plate 122 is positively correlated with the number of wire harnesses 200. The included angle α between the first plate 121 and the second plate 122 is positively correlated with the number of wire harnesses 200 in the first mounting groove 111. Where 0 < α ≤ 85°C.

[0047] In this embodiment, the included angle α between the first plate 121 and the second plate 122 is related to the number of wire harnesses 200. The more wire harnesses 200 there are, the larger the included angle between the first plate 121 and the second plate 122, and the greater the distance between the first plate 121 and the second plate 122 and the bottom of the first mounting groove 111. Conversely, the fewer wire harnesses 200 there are, the smaller the included angle between the first plate 121 and the second plate 122, and the smaller the distance between the first plate 121 and the second plate 122 and the bottom of the first mounting groove 111.

[0048] In some embodiments, see Figure 3 and Figure 4 The width of the first plate 121 is L1, where 5mm ≤ L1 ≤ 10mm. The width L1 of the first plate 121 refers to the distance between the two sides of the first plate 121 along the second direction. The value of L1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or other unlisted values.

[0049] In some embodiments, see Figure 3 and Figure 4 The width of the second plate 122 is L2, where 5mm ≤ L2 ≤ 10mm. The width L2 of the second plate 122 refers to the distance between the two sides of the second plate 122 along the second direction. The value of L2 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or other unlisted values.

[0050] In some embodiments, see Figure 3 and Figure 4 The bottom partition plate 110 of the first mounting groove 111 has a through hole 114, which is opposite to the wire pressing plate 120. Along the thickness direction of the partition plate 110, the projection of the wire pressing plate 120 is located within the through hole 114. For example, along the width direction of the first mounting groove 111, the width of the through hole 114 is L3, where L3-L1 = 1mm or L3-L2 = 1mm.

[0051] In this embodiment, when the pressure plate 120 holds the wire harness 200, the wire harness 200 is easily damaged due to compression deformation. In this embodiment, a through hole 114 is provided directly below the pressure plate 120 to provide clearance for the deformation of the wire harness 200, ensuring that the pressure plate 120 is fixed while protecting the wire harness 200. The width of the through hole 114 is slightly larger than the width of the pressure plate 120, so as to provide sufficient clearance while reducing the probability of the through hole 114 being too large and affecting the structural strength of the isolation plate 110.

[0052] In some embodiments, the pressure plate 120 and the isolation plate 110 are integrally formed. The pressure plate 120 and the isolation plate 110 are made of the same material, such as insulating plastic. The pressure plate 120 and the isolation plate 110 can be integrally formed by injection molding. This facilitates the processing of the pressure plate 120 and the isolation plate 110 and ensures the structural strength of the connection between the pressure plate 120 and the isolation plate 110.

[0053] See Figure 5 This application also provides a CCS assembly 10, including the aforementioned CCS bracket 100. Furthermore, the CCS assembly 10 includes a busbar 300, which is used for electrical connection with the cells in the battery module to realize a series-parallel connection design of multiple cells in the battery module. The CCS assembly 10 of this application embodiment has the same technical effects as the aforementioned CCS bracket 100, and will not be described again.

[0054] See Figure 5 This application also provides a battery pack, including the aforementioned CCS component 10 and battery modules. The CCS component 10 is mounted above the battery modules. The CCS component 10 enables high-voltage series and parallel connection of the battery modules' cells, as well as battery temperature and cell voltage sampling functions, and provides the collected temperature and voltage data to the BMS system. The battery pack of this application embodiment has the same technical effects as the aforementioned CCS bracket 100, and will not be described again.
