[0002] In related technologies, the CCS (cell collection system) component includes a bracket and a wiring harness. The bracket has a wiring channel, and the wiring harness is housed within the wiring channel.

[0003] It is understandable that CCS components can be used in vehicles. When the vehicle is running, the CCS components will move with the vehicle, which may cause the wiring harness to come off the wire channel. Utility Model Content

[0004] This application provides a CCS component, a battery module, a battery pack, and an electrical device, aiming to reduce the possibility of wire harnesses detaching from the wire channel.

[0005] To achieve the above objectives, according to a first aspect of this application, a CCS component is provided, comprising:

[0006] The bracket is provided with a wire passage groove, the wire passage groove having a bottom and an opening opposite to the bottom;

[0007] The wire harness is disposed in the wire passage groove; and

[0008] A limiting member is provided at the slot opening. The limiting member is used to prevent the wire harness from leaving the slot opening along the depth direction of the wire passage groove. Multiple limiting members are provided and are spaced apart along the length direction of the wire passage groove.

[0009] Optionally, the CCS assembly further includes a pressing member disposed in the wire passage groove, wherein at least one of the limiting members presses the wire harness against the groove wall of the wire passage groove through the pressing member.

[0010] Optionally, multiple pressing members are provided, and the multiple pressing members are arranged at intervals along the length direction of the bracket, with one pressing member corresponding to one limiting member.

[0011] Optionally, in the length direction of the bracket, the limiting member does not extend beyond the opposite sides of the corresponding pressing member;

[0012] Alternatively, in the length direction of the bracket, the pressing member does not extend beyond the opposite sides of the corresponding limiting member.

[0013] Optionally, the pressing member is elastic.

[0014] Optionally, the pressure element is configured as foam.

[0015] Optionally, the CCS assembly further includes a busbar, and the bracket includes a bracket body, a partition group, and a limiting protrusion. In the width direction of the bracket, the partition group and the limiting protrusion are spaced apart on the bracket body to separate the wire passage groove. The partition group includes multiple partitions. In the length direction of the bracket, the multiple partitions are spaced apart, and a busbar is provided between two adjacent partitions. One end of the limiting member is connected to a corresponding partition, and the other end is connected to the limiting protrusion.

[0016] Optionally, in the length direction of the bracket, the limiting member does not extend beyond the opposite sides of the corresponding partition.

[0017] And / or, the limiting protrusion is provided with a first clearance hole, the first clearance hole is used to be arranged opposite to the explosion-proof valve of the battery cell, and in the thickness direction of the bracket, the projection of the first clearance hole is located outside the projection of the limiting member.

[0018] According to a second aspect of this application, a battery module is provided, including the aforementioned CCS component.

[0019] According to a third aspect of this application, a battery pack is also provided, including the aforementioned battery module.

[0020] According to a fourth aspect of this application, an electrical device is also provided, including the aforementioned battery pack.

[0021] In the CCS component of this application embodiment, multiple limiting members are arranged at intervals along the length of the wire groove. This interval arrangement can fix the wire harness at multiple points, thereby constraining the wire harness and greatly reducing the risk of the wire harness falling off.

[0022] In addition, since the limiting components are spaced apart rather than one limiting component covering the entire slot, this helps to make the CCS module lighter and achieve the goal of lightweighting the CCS module.

Detailed Implementation

[0033] 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 protection scope of this application.

[0034] According to the first aspect of this application, referring to Figures 1 to 5 This disclosure provides a CCS assembly 100. The CCS assembly 100 includes a bracket 200, a wire harness 310, and a limiting member 600. The bracket 200 has a wire passage groove 240, which has a bottom and an opening opposite to the bottom. The wire harness 310 is disposed in the wire passage groove 240. The limiting member 600 is disposed in the opening and is used to prevent the wire harness 310 from dislodging from the opening along the depth direction of the wire passage groove 240. Multiple limiting members 600 are provided and spaced apart along the length direction of the wire passage groove 240.

[0035] Multiple limiting members 600 are arranged at intervals along the length of the wire groove 240. This interval arrangement can fix the wire harness 310 at multiple points, thereby constraining the wire harness 310 and greatly reducing the risk of the wire harness 310 falling off.

[0036] In addition, since the limiting members 600 are spaced apart, rather than one limiting member 600 covering the entire slot, this helps to make the CCS module 100 lighter and facilitates the weight reduction of the CCS module 100.

[0037] It is worth mentioning that the wire harness 310 is located in the wire channel 240, which should be understood as the wire harness 310 being at least partially located in the wire channel 240.

[0038] In some embodiments, the CCS assembly 100 further includes a busbar 500, and the bracket 200 includes a bracket body 210, a partition group 220, and a limiting protrusion 230. In the width direction of the bracket 200, the partition group 220 and the limiting protrusion 230 are spaced apart on the bracket body 210 to separate the wire passage groove 240. The partition group 220 includes a plurality of partitions 221. In the length direction of the bracket 200, the plurality of partitions 221 are spaced apart. A busbar 500 is provided between two adjacent partitions 221. One end of the limiting member 600 is connected to a corresponding partition 221, and the other end is connected to the limiting protrusion 230.

[0039] In this way, the adjacent busbar 500 will not short-circuit.

[0040] Thus, the partition 221 not only serves as a component for separating adjacent busbars 500, but also serves as a component for restricting the passage of wire troughs 240, and also serves as a component for connecting the limiting member 600, which makes the partition 221 more versatile.

[0041] In some embodiments, in the length direction of the bracket 200, the limiting member 600 does not extend beyond the opposite sides of the corresponding partition 221.

[0042] Thus, in the thickness direction of the bracket 200, the projection of the limiting member 600 is outside the projection of the busbar 500. Therefore, the busbar 500 will not interfere with the limiting member 600 during the installation and removal of the bracket 200, which helps improve the installation and removal efficiency of the CCS assembly 100.

[0043] In some embodiments, the limiting protrusion 230 is provided with a first clearance hole 231, which is used to be disposed opposite to the explosion-proof valve of the battery cell. In the thickness direction of the bracket 200, the projection of the first clearance hole 231 is located outside the projection of the limiting member 600.

[0044] In this way, the gas released by the explosion-proof valve can flow out through the first clearance hole 231. Since the limiting member 600 does not block the first clearance hole 231, the explosion-proof valve has a high pressure relief efficiency, which helps to improve the safety of the battery cell and reduce the occurrence of battery cell explosions.

[0045] In some embodiments, the CCS assembly 100 further includes a pressing member 400 disposed in the wire passage 240, and at least one limiting member 600 presses the wire harness 310 against the wall of the wire passage 240 through the pressing member 400.

[0046] This helps to reduce the movement space of the wiring harness 300. The CCS component 100 can be applied to vehicles. When the vehicle is running, it helps to reduce the shaking of the wiring harness 300, thereby reducing the occurrence of the wiring harness 300 hitting the groove wall of the wire groove 240, and thus reducing the abnormal noise emitted by the CCS component 100.

[0047] In some embodiments, multiple pressing members 400 are provided. In the length direction of the bracket 200, multiple pressing members 400 are arranged at intervals, and one pressing member 400 corresponds to one limiting member 600.

[0048] In this way, if one of the pressure components 400 is damaged, only the corresponding pressure component 400 needs to be replaced, without having to replace all the pressure components 400 at the same time, which helps to reduce the cost of maintaining the CCS component 100.

[0049] However, this design is not limited to this. In some other implementations, multiple limiting ribs press the wire harness 310 against the groove wall of the wire trough 240 through the same rib.

[0050] In some embodiments, in the length direction of the bracket 200, the limiting member 600 does not extend beyond the opposite sides of the corresponding pressing member 400.

[0051] Thus, the larger size of the pressure member 400 helps to reduce the movement space of the wiring harness assembly 300. The CCS assembly 100 can be applied to vehicles. When the vehicle is running, it helps to reduce the shaking of the wiring harness assembly 300, thereby reducing the occurrence of the wiring harness assembly 300 hitting the groove wall of the wire groove 240, and further reducing the abnormal noise emitted by the CCS assembly 100.

[0052] However, this design is not limited to this. In some other embodiments, the pressing member 400 does not extend beyond the opposite sides of the corresponding limiting member 600 in the length direction of the bracket 200.

[0053] In some embodiments, a plurality of pressing members 400 are provided, and the plurality of pressing members 400 are spaced apart in the extending direction of the wire groove 240.

[0054] By arranging multiple pressure members 400 at intervals along the extension direction of the wire channel 240, the fixing force of the wire harness 310 can be distributed to multiple locations. Each pressure member 400 can apply pressure to the wire harness 310 in a local area, thereby ensuring that the wire harness 310 can be set more securely in the wire channel 240, improving the reliability of the wire harness 310 fixing.

[0055] After multiple pressure-bearing components 400 are spaced apart, the wire harness 310 is fixed at multiple locations, forming multiple support points. These support points can effectively limit the vibration and sway of the wire harness 310 within the wire groove 240. Especially under dynamic conditions, they can significantly improve the stability of the wire harness 310 and reduce the risk of wear and damage caused by vibration.

[0056] With multiple retaining components 400 spaced apart, even if one retaining component 400 malfunctions, the others can still function to ensure the secure fixing of the wire harness 310. This redundant design significantly improves system reliability and reduces the risk of system failure due to the failure of a single component.

[0057] However, this design is not limited to this. In some other embodiments, the pressing member 400 extends from one end of the wire groove 240 to the other end of the wire groove 240.

[0058] In addition, the limiting protrusion 230 extends along the length of the bracket 200, and the limiting protrusion 230 and the partition group 220 are spaced apart by a wire groove 240. A pressing member 400 is provided between the limiting protrusion 230 and the partition portion 221 of at least one partition group 220.

[0059] Thus, the partition 221 not only serves as a component for separating adjacent busbars 500, but also functions as a component for restricting the passage of wire troughs 240, which makes the partition 221 more versatile.

[0060] In the width direction of the bracket 200, the opposing sides of the pressing member 400 are restricted by the limiting protrusion 230 and the partition 221, respectively. This helps the pressing member 400 to be set more stably in the wire groove 240, thereby improving the reliability of the wire harness 310 fixing.

[0061] It is worth mentioning that the length direction of the bracket 200 is as follows Figure 5 As shown in the E direction.

[0062] In some embodiments, the bracket 200 further includes a plurality of first reinforcing posts 250, with one first reinforcing post 250 correspondingly disposed on a partition portion 221.

[0063] The first reinforcing post 250 is directly positioned corresponding to the partition 221, providing additional reinforcement to the partition 221. This localized reinforcement design effectively improves the bending and compressive strength of the partition 221, making it less prone to deformation or damage when subjected to external forces. This also makes the partition 221 more stable in shape. When the bracket 200 vibrates, the relative position of the pressing member 400 and the partition 221 remains relatively stable, reducing the likelihood of the pressing member 400 detaching from the partition 221, thereby improving the reliability of the wiring harness 310 fixation.

[0064] Furthermore, multiple first reinforcing columns 250 are distributed along the length of the bracket 200, forming a stable support structure that enhances the overall structural strength and rigidity of the bracket 200. This allows the bracket 200 to better withstand various loads from the wiring harness 310, busbar 500, and the external environment, improving the overall stability of the system.

[0065] By enhancing the strength and stability of the partition 221, the risk of busbar 500 displacement, short circuit, and other faults caused by damage to the partition 221 is reduced, thereby improving the operational reliability of the entire CCS assembly 100.

[0066] In some embodiments, the size of the pressing member 400 along the length of the wire channel 240 ranges from 2 to 5 times the size of the first reinforcing post 250. This ensures that the size of the pressing member 400 is not too small along the length of the wire channel 240, resulting in a larger contact area between the pressing member 400 and the wire harness 310, which improves the reliability of securing the wire harness 310. Furthermore, the size of the pressing member 400 along the length of the wire channel 240 is not too large, which helps save materials and costs.

[0067] In one example, the size of the abutment 400 in the length direction of the through groove 240 is 2, 2.1, 2.5, 2.8, 3, 3.5, 4, 4.5, or 5 times the size of the first reinforcing post 250.

[0068] In some embodiments, along the length of the bracket 200, a first reinforcing post 250 is disposed between the opposite ends of the corresponding pressing member 400. Thus, along the length of the bracket 200, the positions of the two ends of the pressing member 400 relative to the separating portion 221 are relatively stable, which helps to improve the reliability of the fixed wire harness 310.

[0069] However, this design is not limited to this. In some other embodiments, in the width direction of the bracket 200, one end of the pressing member 400 is disposed opposite to the first reinforcing column 250, and the other end is disposed offset from the first reinforcing column 250.

[0070] It is worth mentioning that the width direction of bracket 200 is as follows Figure 5 As shown in direction D in the diagram.

[0071] In some embodiments, the size of the pressing member 400 ranges from 10 mm to 30 mm along the length of the wire channel 240. This ensures that the size of the pressing member 400 is not too small along the length of the wire channel 240, allowing for a larger contact area between the pressing member 400 and the wire harness 310, which improves the reliability of securing the wire harness 310. Furthermore, the size of the pressing member 400 is not too large along the length of the wire channel 240, which helps save materials and costs.

[0072] In one example, the dimensions of the pressing member 400 may be, but are not limited to, 10mm, 11mm, 12mm, 12.2mm, 13mm, 14mm, 15mm, 16mm, 17mm, 17.3mm, 18mm, 19mm, 20mm, 20.9mm, 21mm, 22mm, 23mm, 23.6mm, 24mm, 25mm, 26mm, 27mm, 27.6mm, 28mm, 29mm, or 30mm.

[0073] In some embodiments, the bracket 200 further includes a plurality of second reinforcing posts 260, which are disposed on the limiting protrusion 230. In the width direction of the bracket 200, a first reinforcing post 250 and a second reinforcing post 260 are disposed opposite to each other.

[0074] The first reinforcing column 250 and the second reinforcing column 260 are respectively located at different positions on the bracket 200 and are arranged opposite each other in the width direction, forming a multi-dimensional reinforcement structure. This design not only enhances the strength of the bracket 200 in the length direction, but also significantly improves the bending and torsional resistance of the bracket 200 in the width direction.

[0075] With the first reinforcing post 250 and the second reinforcing post 260 arranged opposite each other in the width direction, the overall structure of the bracket 200 is more stable and can better withstand loads from different directions, including the weight of the wiring harness 310, the busbar 500 and the impact force of the external environment.

[0076] Furthermore, a second reinforcing post 260 is provided on the limiting protrusion 230 to reinforce it. This localized reinforcement design effectively improves the bending and compressive strength of the limiting protrusion 230, making it less prone to deformation or damage when subjected to external forces. This also ensures greater stability of the limiting protrusion 230's shape. When the bracket 200 vibrates, the relative position of the pressing member 400 and the limiting protrusion 230 remains relatively stable, reducing the likelihood of the pressing member 400 detaching from the limiting protrusion 230 and thus improving the reliability of the wiring harness 310's fixation.

[0077] In some embodiments, one end of the limiting member 600 is riveted to the first reinforcing post 250, and the other end is riveted to the second reinforcing post 260.

[0078] Thus, the first reinforcing post 250 and the second reinforcing post 260 are also reused as components for connecting to the limiting member 600, which makes the functions of the first reinforcing post 250 and the second reinforcing post 260 more diverse. In addition, in one example, the limiting member 600 is hot-riveted to the first reinforcing post 250 and also hot-riveted to the second reinforcing post 260. It can be understood that at this time, the first reinforcing post 250 is configured as the first hot-riveted post, and the second reinforcing post 260 is configured as the second hot-riveted post.

[0079] After the limiting member 600 is installed in the slot, the pressing member 400 and the wire harness 310 are tightly fixed between the bottom of the slot and the limiting member 600, ensuring that the wire harness 310 remains stable throughout the wire trough 240 and reducing the occurrence of displacement or loosening due to external forces.

[0080] In addition, the riveting design of the limiting member 600 with the first reinforcing post 250 and the second reinforcing post 260 significantly improves the fixing effect of the wire harness 310 and the pressing member 400.

[0081] In some other embodiments, the limiting member 600 is integrally formed with the bracket 200.

[0082] In some embodiments, the CCS assembly 100 includes a wire harness group 300, which includes multiple wire harnesses 310. The wire harness group 300 is disposed in a wire channel 240, which has a first end and a second end opposite to each other. The wire harness group 300 is gradually tapered in the direction from the first end to the second end, and the distance between the limiting member 600 and the bottom of the channel gradually decreases in the direction from the first end to the second end.

[0083] The distance between the limiting member 600 and the bottom of the groove gradually decreases, matching the tapered shape of the wire harness assembly 300, thus better conforming to the shape of the wire harness assembly 300. This self-adaptive fixing method can further improve the stability of the wire harness 310 and reduce the risk of wear or damage caused by the swaying or displacement of the wire harness 310.

[0084] It is worth mentioning that, since the multiple wire harnesses 310 of the wire harness group 300 are connected to multiple busbars 500 respectively, the wire harness group 300 is set in a gradually narrowing direction from the first end to the second end.

[0085] In some embodiments, the partition group 220 is provided in two groups. In the width direction of the bracket 200, the limiting protrusion 230 is provided between the two partition groups 220. The limiting protrusion 230 and the two adjacent partition groups 220 respectively restrict a wire passage groove 240. The wire passage groove 240 is provided with a wire harness 310. The two groove openings are respectively provided with limiting members 600.

[0086] In some embodiments, the pressure member 400 is elastic.

[0087] The elastic retaining element 400 can adaptively adjust to the shape and size of the wire harness 310, closely fitting the surface of the wire harness 310, thereby providing a more uniform and reliable fixing effect. This close fit can effectively prevent the wire harness 310 from loosening or shifting within the wire channel 240.

[0088] The elastic pressure member 400 can absorb and buffer external impact forces to a certain extent, reduce wear or damage to the wire harness 310 caused by vibration or external force, and further improve the fixing stability of the wire harness 310.

[0089] In some embodiments, the pressure member 400 is configured as foam. The availability and low cost of foam help reduce the manufacturing cost of the CCS assembly 100. However, the design is not limited thereto; in some other embodiments, the pressure member 400 is configured as rubber.

[0090] In some embodiments, the pressing member 400 is bonded to the wall surface of the wire groove 240.

[0091] By bonding the pressure member 400 to the wall of the wire trough 240, the pressure member 400 can be kept stable throughout the use process, reducing the possibility of displacement due to external forces. This strong bonding method significantly improves the fixation effect of the wire harness 310.

[0092] However, this design is not limited to this. In some other embodiments, the pressing member 400 is welded to the wall of the cable tray 240.
