[0002] In related technologies, the CCS (cell collection system) component includes a bracket, cable ties, and a wire harness. The bracket has two through holes for the two ends of the cable ties to pass through, thereby binding the wire harness to the bracket. To ensure that the wire harness can be stably fixed to the bracket, the cable ties need to be tightly bound to the bracket. This causes the cable ties to exert a large force on the bracket, specifically on the walls of the through holes, which makes the bracket more susceptible to damage. Utility Model Content

It can be understood that the bonding process is simple and convenient, and the bracket and the adapter can be bonded together without applying a large force, which greatly reduces the probability of the bracket being damaged when the wire harness is placed on the bracket.

[0023] Furthermore, it is worth mentioning that since the adapter is bonded to the bracket, the connection position of the adapter on the bracket can be quite flexible. The position of the adapter bonded to the bracket can be flexibly adjusted according to the user's actual needs. In other words, the position of the wiring harness on the bracket can be flexibly adjusted according to the user's actual needs, which is conducive to meeting the user's personalized needs.

Detailed Implementation

[0037] 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.

[0038] According to the first aspect of this application, referring to Figures 1 to 6 This disclosure provides a CCS assembly, which includes a bracket 200, an adapter 300, and a wiring harness 910. The adapter 300 is bonded to the bracket 200. The wiring harness 910 is mounted on the adapter 300.

[0039] In this way, the wire harness 910 can be installed on the adapter 300 first. No matter how much force is applied to the adapter 300 during the installation of the wire harness 910, the bracket 200 will not be damaged. After the wire harness 910 is installed on the adapter 300, the adapter 300 and the wire harness 910 can be bonded to the bracket 200 as a whole through the adapter 300. It can be understood that the bonding process is simple and convenient, and the bracket 200 and the adapter 300 can be bonded together without applying a large force, which greatly reduces the probability of the bracket 200 being damaged when the wire harness 910 is placed on the bracket 200.

[0040] Furthermore, it is worth mentioning that since the adapter 300 is bonded to the bracket 200, the connection position of the adapter 300 on the bracket 200 can be quite flexible. The position of the adapter 300 bonded to the bracket 200 can be flexibly adjusted according to the user's actual needs. In other words, the position of the wire harness 910 on the bracket 200 can be flexibly adjusted according to the user's actual needs, which is conducive to meeting the user's personalized needs.

[0041] It should be noted that the entire wiring harness 910 can be indirectly connected to the bracket 200 via the adapter 300; or a portion of the wiring harness 910 can be indirectly connected to the bracket 200 via the adapter. No restrictions are imposed.

[0042] In addition, the way the adapter 300 is bonded to the bracket 200 also facilitates the automation of CCS component assembly.

[0043] In some embodiments, the adapter 300 includes a base body 400 and a buffer pad 700. The buffer pad 700 is disposed on the base body 400, and the base body 400 is bonded to the bracket 200 via the buffer pad 700. The wiring harness 910 is mounted on the base body 400. It is understood that the buffer pad 700 has a certain degree of flexibility. This reduces the possibility of the adapter 300 scratching the bracket 200 during the bonding process, and helps the bracket 200 maintain high structural strength after the adapter 300 is bonded to the bracket 200.

[0044] There are many ways to mount the wire harness 910 to the adapter 300. In some embodiments, the CCS assembly also includes a binding strap 920, through which the wire harness 910 is mounted to the adapter 300.

[0045] The binding strap 920 can effectively fix the wire harness 910, preventing it from loosening or shifting due to vibration, collision or other reasons during assembly and use, thereby improving the fixing reliability of the wire harness 910.

[0046] The use of the binding strap 920 makes the fixing of the wire harness 910 more flexible and convenient. The assembly position can be adjusted according to actual needs, while reducing the reliance on complex fixing structures and simplifying the assembly process.

[0047] In environments with high vibration, the binding strap 920 can effectively restrain the movement of the wire harness 910, preventing the connectors from becoming loose or making poor contact due to the forced movement of the wire harness 910.

[0048] In some embodiments, the binding strap 920 is configured as a cable tie. In one example, the cable tie is designed with a backstop function, tightening as it is secured, enabling quick binding while ensuring the wire harness 910 or other items are firmly fixed. However, this design is not limited to this; in some other embodiments, the binding strap 920 is configured as a Velcro strap.

[0049] In some embodiments, the adapter 300 is provided with a first limiting channel 810, which is used for the binding strap 920 to pass through.

[0050] The first limiting channel 810 provides a clear path for the binding strap 920, enabling the binding strap 920 to more tightly secure the wire harness 910 and prevent the wire harness 910 from loosening due to vibration or external force during use.

[0051] The design of the first limiting channel 810 ensures the accurate positioning of the binding strap 920 during assembly, preventing the wire harness 910 from being loosely fixed or having an untidy appearance due to improper positioning of the binding strap 920.

[0052] The assembly process of the strap 920 via the first limiting channel 810 is more standardized and simplified, reducing assembly time and the complexity of manual operation.

[0053] The first limiting channel 810 can prevent the binding strap 920 from accidentally slipping or misaligning during assembly, thereby ensuring the fixed reliability of the wire harness 910 throughout its service life and reducing safety hazards caused by the loosening of the wire harness 910.

[0054] There are many structural forms of the adapter 300. In some embodiments, the adapter 300 includes a base 410, a base 500, and a support 600. In the thickness direction of the base 410, the base 410 has a first side and a second side. The first side is bonded to the bracket 200, and the support 600 is disposed on the second side. The base 500 and the second side are spaced apart. The base 500 is connected to the base 410 through the support 600. The base 500, the support 600, and the second side together form a first limiting channel 810. The base 500 is used to place the wire harness 910.

[0055] The design of the base 500 and the support 600 makes the adapter 300 more structurally stable. The support 600 connects the base 410 and the base 500 to form a stable support structure that can effectively withstand the weight and external forces of the wire harness 910 and related components.

[0056] The second side of the base 500, support 600, and seat 410 together form the first limiting channel 810, providing space for the binding strap 920 to pass through. This design can effectively restrain the binding strap 920 and prevent it from loosening due to vibration or external force during use.

[0057] The design of the first limiting channel 810 provides a clear path for the threading of the binding strap 920, making the assembly process more standardized and efficient. This structure can reduce human error during assembly and improve the overall assembly quality.

[0058] Since the binding strap 920 is installed in the first limiting channel 810, it can be quickly positioned and operated when the binding strap 920 needs to be replaced.

[0059] However, this design is not limited to this. In some other embodiments, the structure of the adapter 300 can also be other, which is not limited here, as long as it can be attached to the bracket 200 and is provided with the first limiting channel 810.

[0060] It is worth mentioning that, in some embodiments, the seat body 400 includes a seat body 410, a support platform 500, and a support portion 600. In some embodiments, the seat body 410 can be bonded to the bracket 200 via a cushioning pad 700, or it can be directly bonded to the bracket 200; no limitation is made here.

[0061] In some embodiments, the support portion 600 includes a plurality of support ribs 610, which connect the second side and the support platform 500.

[0062] Multiple support ribs 610 can effectively disperse and transfer loads, improving the overall stability of the adapter 300.

[0063] Multiple support ribs 610 can distribute stress to multiple support points, avoid stress concentration, and thus improve the durability and reliability of the structure.

[0064] This design can adapt to different usage environments and working conditions. For example, in scenarios with large vibrations or complex stresses, multiple support ribs 610 can provide more reliable support.

[0065] In some embodiments, the support rib 610 has a first end 611 and a second end 612 opposite to each other. The first end 611 is connected to the second side, and the second end 612 is connected to the bearing platform 500. The support rib 610 is tapered from the first end 611 to the second end 612. This tapering design can improve the load-bearing capacity of the structure without increasing the amount of material used. This design saves materials, reduces the overall weight, and lowers production costs.

[0066] In some embodiments, the platform 500, the support 600, and the second side together form a second limiting channel 820, and the first limiting channel 810 and the second limiting channel 820 are used for the binding strap 920 to be threaded through.

[0067] The design of the first limiting channel 810 and the second limiting channel 820 provides multiple fixing paths for the cable tie 920, allowing users to select the appropriate channel to fix the wire harness 910 according to actual needs. This flexibility can meet the usage requirements in different scenarios and improve the versatility of the components.

[0068] In some embodiments, the first limiting channel 810 and the second limiting channel 820 at least partially overlap.

[0069] The overlapping design of the passages allows for multiple fixing methods within a limited space, reducing space waste caused by setting up multiple independent passages.

[0070] In some embodiments, the extension direction of the first limiting channel 810 is different from the extension direction of the second limiting channel 820.

[0071] The two limiting channels extend in different directions, which can meet the fixing requirements of wire harness 910 in different directions. This allows the wire harness 910 to select the appropriate channel for fixing according to the actual layout, thereby improving the flexibility of wire harness 910 management.

[0072] In some embodiments, the base 410 is provided with a weight-reducing hole 411 extending from the first side to the second side.

[0073] The design of the weight-reducing hole 411 can remove unnecessary material from the base 410, significantly reducing the overall weight without affecting the overall load-bearing capacity and stability of the structure. This is especially important for applications requiring lightweighting (such as automotive and aerospace), as it can improve energy efficiency and reduce energy consumption.

[0074] In some embodiments, one side of the adapter 300 is bonded to the bracket 200 in the height direction of the adapter 300, and the height dimension of the adapter 300 is smaller than the width dimension of the adapter 300.

[0075] The adapter 300 is wider than its height, which gives it a larger bonding area and enhances the stability of the overall structure.

[0076] The design, with a width greater than its height, gives the adapter 300 higher rigidity when subjected to bending and torsional forces, effectively reducing deformation caused by external forces.

[0077] In some embodiments, the support 200 is configured as a vacuum-formed support 200. Vacuum forming molds are relatively simple and low-cost, and compared to injection molds, their development difficulty is lower, effectively reducing initial equipment investment. The vacuum forming process can adjust the material thickness and shape according to requirements, reducing material waste and thus lowering raw material costs. Vacuum forming has a short cycle time and fast production speed, making it suitable for mass production and further reducing the cost per unit product. Vacuum-formed supports 200 typically use lightweight, thin flame-retardant PC films and other materials, which are lighter than traditional injection-formed supports 200, effectively reducing the overall weight of the CCS module while improving the space utilization of the battery pack. The PC material commonly used in vacuum-formed supports 200 has good insulation properties, meeting the electrical insulation requirements of CCS modules in the battery pack. Vacuum-formed products have good corrosion resistance, adapting to the complex chemical environment inside the battery pack. The vacuum forming process can quickly adjust the product shape and size according to different design requirements, adapting to the diverse structural requirements of CCS modules. Vacuum-formed supports 200 can be integrated with other components through simple processes such as cutting and hot riveting, simplifying the production process and facilitating automated assembly. The materials used in the 200 vacuum forming stand, such as PC, have good recyclability and meet environmental protection requirements.

[0078] In some embodiments, the CCS assembly further includes a bus 930 disposed on the bracket 200, and a wiring harness 910 connected to the bus 930. In one example, the bus 930 is configured as an aluminum bus.
