Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0029] The following is combined Figure 1 and Figure 2 This application describes the CCS component, battery module, battery pack, and electrical device.

[0030] According to the embodiments of the first aspect of this application, such as Figure 1 and Figure 2 As shown, the CCS assembly includes a bracket 1, a busbar 2, a wire harness 3, and an adhesive part 4. The bracket 1 has a mounting groove 11 and a wire groove 12. The busbar 2 is mounted in the mounting groove 11. One end of the wire harness 3 is connected to the busbar 2. At least a portion of the wire harness 3 is located in the wire groove 12. The adhesive part 4 is connected to the bracket 1 and is connected to the wire harness 3. The adhesive part 4 is used to fix the wire harness 3.

[0031] According to the CCS assembly of this application embodiment, the mounting groove 11 of the bracket 1 can limit the busbar 2, which helps to improve the installation stability of the busbar 2. The wire groove 12 of the bracket 1 can limit the wire harness 3, which helps to improve the stability of the wire harness 3. When fixing the wire harness 3, the wire harness 3 is first placed in the wire groove 12, and then the wire harness 3 is fixed to the bracket 1 by the glue part 4. Since the glue part 4 can be connected to the bracket 1 by dispensing glue or other methods, it is conducive to automation, reduces the time required to fix the wire harness 3, and improves production efficiency.

[0032] Understandably, existing technologies require wrapping multiple wire harnesses 3 together with cloth and then securing the cloth and wire harnesses 3 with cable ties. This process is cumbersome, time-consuming, and difficult to automate. This application, however, eliminates the cloth wrapping and cable ties, directly using the adhesive part 4 to fix the wire harnesses 3 and the bracket 1 together. Since the adhesive part 4 can be applied to the bracket 1 via dispensing or heat sealing, it facilitates automation of wire harness fixation, simplifying the operation, reducing the time required to fix the wire harnesses 3, and improving production efficiency. Furthermore, some adhesive parts 4 can be positioned between different wire harnesses 3, thus securing them together and preventing the wire harnesses 3 from becoming tangled.

[0033] In some embodiments, the adhesive portion 4 is formed on the bracket 1 by dispensing adhesive.

[0034] Understandably, by dispensing adhesive, an adhesive portion 4 is formed at the bracket 1, which allows the wire harness 3 to be fixed together with the bracket 1. Furthermore, automated dispensing using a dispensing device facilitates the automation of the wire harness 3 fixing process, thereby reducing the time required to fix the wire harness 3 and improving production efficiency.

[0035] In some examples, the wire harness 3 is first placed in the wire groove 12, and then glue is applied to the location of the wire harness 3 to form the glue part 4. The glue part 4 can fix the wire harness 3 while being fixedly connected to the bracket 1. At the same time, the glue part 4 can fix different wire harnesses 3 together to prevent the wire harnesses 3 from scattering.

[0036] In some embodiments, the adhesive portion 4 is disposed around the wire harness 3.

[0037] Understandably, the glue part 4 surrounds the wire harness 3, so that the glue part 4 can be fixed together with the wire harness 3, and the glue part 4 is also fixed to the bracket 1, so that the glue part 4 can fix the wire harness 3 to the bracket 1.

[0038] In some examples, a portion of the adhesive part 4 is first placed at the bottom of the wire trough 12 by dispensing adhesive. Then, the wire harness 3 is placed on the portion of the adhesive part 4. Then, adhesive is dispensed on the portion of the adhesive part 4 by dispensing adhesive again. The newly dispensed adhesive will be integrally formed with the portion of the adhesive part 4 to form a complete adhesive part 4, while wrapping the wire harness 3 inside, thereby fixing the wire harness 3.

[0039] In some embodiments, the wire harness 3 is located between the adhesive portion 4 and the bracket 1.

[0040] It is understandable that the glue part 4 and the bracket 1 are fixedly connected. The wire harness 3 is placed between the glue part 4 and the bracket 1. The glue part 4 can fix the wire harness 3 to the bracket 1, thereby fixing the wire harness 3.

[0041] In some examples, the wire harness 3 is first placed in the wire groove 12, and then glue part 4 is formed on the wire harness 3 by dispensing glue. While the glue part 4 is fixedly connected to the bracket 1, part of the glue part 4 covers the top of the wire harness 3 to fix the wire harness 3 between the glue part 4 and the bracket 1, thus ensuring the stability of the wire harness 3 installation.

[0042] In some embodiments, both ends of the adhesive portion 4 protrude from the wire harness 3 along the width direction of the bracket 1.

[0043] Understandably, one end of the adhesive part 4 protrudes from one side of the wire harness 3, and the other end of the adhesive part 4 protrudes from the other side of the wire harness 3. Therefore, in the width direction of the bracket 1, the adhesive part 4 can fix all the wire harness 3, preventing any part of the wire harness 3 from being unsecured and causing it to wobble. Simultaneously, the portion of the adhesive part 4 protruding from the wire harness 3 is fixedly connected to the bracket 1, and the portion of the adhesive part 4 protruding from the wire harness 3 is also fixedly connected to the bracket 1, thus ensuring the stability of the connection between the adhesive part 4 and the bracket 1, allowing the adhesive part 4 to stably fix the wire harness 3 to the bracket 1.

[0044] In some embodiments, the bracket 1 is formed with a receiving groove for receiving the adhesive portion 4.

[0045] It is understandable that by forming a receiving groove at the bracket 1 to accommodate the glue part 4, the receiving groove can limit the glue part 4, which helps to improve the stability of the glue part 4, so that the glue part 4 can stably fix the wire harness 3 to the bracket 1.

[0046] It is understandable that the design of the receiving groove helps to increase the contact area between the glue part 4 and the bracket 1, thereby improving the connection stability between the glue part 4 and the bracket 1.

[0047] Understandably, the inclusion of a receiving groove helps to increase the volume of the adhesive part 4, thereby improving the connection stability between the adhesive part 4 and the bracket 1.

[0048] Specifically, the sidewall of the trough 12 has a receiving groove.

[0049] It is understandable that by forming a receiving groove on the side wall of the wire groove 12, when the glue part 4 is set by dispensing glue, some of the glue part 4 will flow into the receiving groove on the side wall of the wire groove 12, which improves the connection stability between the glue part 4 and the bracket 1, and thus helps to improve the installation stability of the wire harness 3.

[0050] Specifically, the bottom wall of the trough 12 has a receiving groove.

[0051] It is understandable that by forming a receiving groove on the bottom wall of the wire trough 12, when the glue part 4 is set by dispensing glue, some of the glue part 4 will flow into the receiving groove on the bottom wall of the wire trough 12, which improves the connection stability between the glue part 4 and the bracket 1, and thus helps to improve the installation stability of the wire harness 3.

[0052] In some examples, receiving grooves can be provided on both the side wall and the bottom wall of the wire groove 12, thereby effectively improving the connection stability between the glue part 4 and the bracket 1.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the support 1 also includes a frame body 13 and a partition rib 14. The CCS assembly includes at least two busbars 2. The partition rib 14 and at least two busbars 2 are located on the same side of the frame body 13. The at least two busbars 2 are spaced apart along the length direction of the support 1. In the length direction of the support 1, the partition rib 14 is located between two adjacent busbars 2.

[0054] Understandably, the separator 14 can prevent two adjacent busbars 2 from directly contacting each other, thereby reducing abnormal current flow through the busbars 2.

[0055] In some embodiments, there are multiple adhesive portions 4, which are spaced apart along the length of the bracket 1.

[0056] It is understandable that by setting the glue part 4 at different positions, the wire harness 3 can be fixedly connected to the bracket 1 at different positions under the action of the glue part 4, thereby effectively improving the installation stability of the wire harness 3.

[0057] In some examples, multiple adhesive portions 4 are evenly spaced. The spacing between adhesive portions 4 can be adjusted according to the density of the wire bundle 3 at different locations. For example, if the density of the wire bundle 3 in the first segment is less than that in the second segment, then the spacing between adhesive portions 4 in the first segment can be greater than that in the second segment.

[0058] In some embodiments, along the length of the bracket 1, the bracket 1 includes a first end and a second end disposed opposite to each other, the first end of the wire harness 3 is connected to the busbar 2, and the second end of the wire harness 3 extends along the length of the bracket 1 and protrudes from the second end of the bracket 1.

[0059] Understandably, multiple busbars 2 are sequentially arranged along the direction from the first end to the second end of the bracket 1. Each busbar 2 is connected to a wire harness 3. The first end of the wire harness 3 is connected to the busbar 2, and the second end of each wire harness 3 extends towards and protrudes from the second end of the bracket 1 to facilitate the connection of the wire harness 3 with other components. Since at least some of the wire harnesses 3 share a wire groove 12, the closer to the second end of the bracket 1, the more wire harnesses 3 there are.

[0060] Specifically, the density of the adhesive portion 4 gradually increases along the direction from the first end of the bracket 1 to the second end of the bracket 1.

[0061] It is understandable that the number of wire harnesses 3 gradually increases along the direction from the first end of the bracket 1 to the second end of the bracket 1. Therefore, the density of the glue part 4 is set to gradually increase along the direction from the first end of the bracket 1 to the second end of the bracket 1, so that the number of glue parts 4 is also greater in the positions where there are more wire harnesses 3, ensuring that the glue part 4 can effectively fix the wire harnesses 3, so that the wire harnesses 3 in different positions can maintain installation stability.

[0062] Specifically, the width of the adhesive portion 4 gradually increases along the direction from the first end of the bracket 1 to the second end of the bracket 1.

[0063] It is understandable that the number of wire harnesses 3 gradually increases along the direction from the first end of the bracket 1 to the second end of the bracket 1. Therefore, the width of the glue part 4 is set to gradually increase along the direction from the first end of the bracket 1 to the second end of the bracket 1, so that the glue part 4 is wider in the position where there are more wire harnesses 3, ensuring that the glue part 4 can effectively fix the wire harnesses 3, so that the wire harnesses 3 in different positions can maintain installation stability.

[0065] According to the battery module of this application embodiment, the mounting groove 11 of the bracket 1 can limit the busbar 2, which is beneficial to improving the installation stability of the busbar 2. The wire groove 12 of the bracket 1 can limit the wire harness 3, which is beneficial to improving the stability of the wire harness 3. When fixing the wire harness 3, the wire harness 3 is first placed in the wire groove 12, and then the wire harness 3 is fixed to the bracket 1 by the glue part 4. Since the glue part 4 can be connected to the bracket 1 by dispensing glue or other methods, it is beneficial to realize automation, reduce the time required to fix the wire harness 3, and thus improve the production efficiency of the battery module.
