The busbar 200 is installed in the first recessed area 110 and is fixedly connected to the bracket 100. The busbar 200 can be fixed on the bracket 100 by a buckle structure.

[0047] Referring to Figure 1 And Figure 2 The flexible circuit member 300 is a flexible circuit board in a strip shape. The flexible circuit member 300 is adapted to the shape and size of the second recessed area 120 and is installed in the second recessed area 120. In some embodiments, the first elastic piece 140 is located on at least one side of the flexible circuit member 300, and the first elastic piece 140 is located on the side of the flexible circuit member 300 away from the bottom of the second recessed area 120, and the first elastic piece 140 presses and fixes the flexible circuit member 300.

[0048] Referring to Figure 1 And Figure 1The nickel sheet 400 is installed in the third recessed area 130, and the shape and size of the nickel sheet 400 are matched with those of the third recessed area 130. The nickel sheet 400 is located between the bus bar 200 and the flexible circuit member 300. The nickel sheet 400 has a first end and a second end, the first end of the nickel sheet 400 is welded with the bus bar 200, and the second end of the nickel sheet 400 is welded with the flexible circuit member 300. In some embodiments, the second elastic sheet 150 is located on the side of the nickel sheet 400 away from the bottom of the third recessed area 130, and the second elastic sheet 150 presses the nickel sheet 400 to be fixed in the third recessed area 130. The assembly steps of the CCS assembly 10 are as follows: after the nickel sheet 400 is assembled with the flexible circuit member 300, the whole is assembled with the support 100, the bus bar 200 is assembled with the support 100, and then the nickel sheet 400 is welded with the bus bar 200.

[0049] In the embodiments of the present application, the CCS assembly 10 includes the support 100, the bus bar 200, the flexible circuit member 300, and the nickel sheet 400, the nickel sheet 400 is welded with the bus bar 200 and the flexible circuit member 300, the flexible circuit member 300 is fixed in the second recessed area 120 by the first elastic sheet 140, and the nickel sheet 400 is fixed in the third recessed area 130 by the second elastic sheet 150. The flexible circuit member 300 and the nickel sheet 400 are assembled with the support 100 in an integrated manner, which is simple to operate, stable in connection, and improves the processing efficiency and structural stability of the CCS assembly 10.

[0050] In some embodiments, referring to Figure 1 The second recessed area 120 extends along a first direction, the third recessed area 130 extends along a second direction, the first direction and the second direction are arranged perpendicularly, and a plurality of third recessed areas 130 are arranged at intervals along the first direction. The first direction is the length direction of the support 100, and the second direction is the width direction of the support 100. For example, the bus bar 200 includes a plurality of aluminum bars, each aluminum bar corresponds to a third recessed area 130, and the nickel sheet 400 located in the third recessed area 130 is connected to a corresponding aluminum bar.

[0051] In some embodiments, referring to Figure 1 The second recessed area 120 includes a first side edge 121 and a second side edge 122 arranged oppositely. The first side edge 121 and the second side edge 122 extend along the length direction of the support 100. The first side edge 121 is closer to the first recessed area 110 than the second side edge 122, and the first side edge 121 and the second side edge 122 are both provided with a plurality of first elastic sheets 140. The plurality of first elastic sheets 140 are arranged at intervals along the length direction of the support 100. For example, the interval between any adjacent first elastic sheets 140 is the same.

[0052] In the embodiments of the present application, the first elastic pieces 140 are arranged on the first side edge 121 and the second side edge 122 of the second recessed area 120, and press and fix the flexible circuit member 300 from both sides of the flexible circuit member 300, thereby improving the stability of the installation of the flexible circuit member 300 and reducing the occurrence of the bulging of the flexible circuit member 300.

[0053] In some embodiments, referring to Figure 1 , the first elastic pieces 140 on the first side edge 121 are staggered with the first elastic pieces 140 on the second side edge 122. By reducing the number of the first elastic pieces 140, more pressing positions are formed along the length direction of the flexible circuit member 300, thereby improving the stability of the installation of the flexible circuit member 300 and reducing the cost.

[0054] In other embodiments, the first elastic pieces 140 on the first side edge 121 are arranged in alignment with the first elastic pieces 140 on the second side edge 122.

[0055] In some embodiments, referring to Figure 5 , one first elastic piece 140 is arranged on the first side edge 121 between adjacent third recessed areas 130. The first elastic piece 140 is arranged at a position away from the position where the third recessed area 130 communicates with the second recessed area 120, so as to avoid the interference between the first elastic piece 140 and the nickel sheet 400.

[0056] In some embodiments, referring to Figure 1 , the distance between any adjacent first elastic pieces 140 on the first side edge 121 is S1, and 50mm≤S1≤100mm. The value of S1 can be 50mm, 60mm, 70mm, 75mm, 80mm, 85mm, 90mm or other values not listed.

[0057] In the embodiments of the present application, the distance between the first elastic pieces 140 arranged on the same side along the length direction of the bracket 100 is designed reasonably, so as to ensure the stable fixation of the flexible circuit member 300, reduce the probability of the occurrence of the bulging of the flexible circuit member 300 due to the excessively large gap between the first elastic pieces 140, and facilitate the installation of the flexible circuit member 300.

[0058] In some embodiments, referring to Figure 5 and Figure 3 , the flexible circuit member 300 comprises a FFC plate (flexible flat cable) or a FPC plate (flexible printed circuit board).

[0059] For example, referring to Figure 4The flexible circuit member 300 includes an FFC plate and an FFC connector. The FFC connector is located at one end of the FFC plate, and the FFC plate is fixedly connected with the FFC connector. The FFC plate has a long strip-shaped structure. The FFC plate has a larger width at one end close to the FFC connector than at the other end. Correspondingly, the second recessed area 120 has a shape matching that of the FFC plate. The second recessed area 120 has an opening at one end, and the opening is located at an end of the support 100 and extends outward from the FFC plate at the end close to the FFC connector. One or more second recessed areas 120 can be provided on the support 100.

[0060] For example, referring to Figure 4 The flexible circuit member 300 includes an FPC plate and an FPC connector. The FPC connector is located at one end of the FPC plate, and the FPC connector is fixedly connected with the FPC plate. The FPC plate has a long strip-shaped structure. The FPC plate has a larger width at one end close to the FFC connector than at the other end. Correspondingly, the second recessed area 120 has a shape matching that of the FFC plate. The second recessed area 120 has an opening at one end, and the opening is located at an end of the support 100 and extends outward from the FFC plate at the end close to the FFC connector. One or more second recessed areas 120 can be provided on the support 100.

[0061] In some embodiments, referring to Figure 5 The distance between the first elastic sheet 140 and the support 100 at the bottom of the second recessed area 120 is D1, and the thickness of the flexible circuit member 300 is d1, where 0.5mm≤D1-d1≤1.0mm. D1 refers to the vertical distance between the side of the first elastic sheet 140 close to the support 100 and the upper surface of the support 100 at the bottom of the second recessed area 120. The value of D1-d1 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or other values not listed.

[0062] In the embodiments of the present application, D1 is greater than d1, and the first elastic sheet 140 is spaced apart from the flexible circuit member 300 by a certain distance, which facilitates the entry of the flexible circuit member 300 into the second recessed area 120 and reduces the probability of damage to the flexible circuit member 300 caused by excessive pressure of the first elastic sheet 140 on the surface of the flexible circuit member 300. It also reduces the probability of the flexible circuit member 300 moving out of the second recessed area 120 due to excessive gap between the first elastic sheet 140 and the flexible circuit member 300.

[0063] In some embodiments, referring to Figure 6 The distance between the second elastic sheet 150 and the support 100 at the bottom of the third recessed area 130 is D2, and the thickness of the nickel sheet 400 is d2, where 0.5mm≤D2-d2≤1.0mm. The value of D2-d2 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or other values not listed.

[0064] In the embodiments of the present application, D2 is greater than d2, and the second elastic sheet 150 is spaced apart from the nickel sheet 400 by a distance, so as to facilitate the nickel sheet 400 to enter the third recessed area 130 and reduce the probability of damage to the nickel sheet 400 caused by overpressure of the second elastic sheet 150 on the nickel sheet 400. The probability of the nickel sheet 400 moving out of the third recessed area 130 caused by too large gap between the second elastic sheet 150 and the nickel sheet 400 is reduced.

[0065] In some embodiments, the thickness of the nickel sheet 400 is the same as the thickness of the flexible circuit member 300. The depth of the second recessed area 120 is the same as the depth of the third recessed area 130.

[0066] In some embodiments, referring to Figure 7 , the width of the third recessed area 130 is L, and the width of the second elastic sheet 150 is l, where 0.3L≤l≤0.4L. The width of the third recessed area 130 refers to the distance between the opposite two side edges of the third recessed area 130 along the width direction of the support 100. The width of the second elastic sheet 150 refers to the distance between the opposite two ends of the second elastic sheet 150 along the width direction of the support 100. For example, the value of l can be 0.3L, 0.32L, 0.35L, 0.38L, 0.4L or other values not listed.

[0067] In the embodiments of the present application, the width of the second elastic sheet 150 is less than the width of the third recessed area 130, and the end of the second elastic sheet 150 is spaced apart from one side edge of the third recessed area 130 by a distance. If l is less than 0.3L, the position of the second elastic sheet 150 abutting against the nickel sheet 400 is small, which is not conducive to the fixation of the nickel sheet 400. If l is greater than 0.4L, the distance between the end of the second elastic sheet 150 and the opposite side of the third recessed area 130 is small, which is not conducive to the nickel sheet 400 to enter the third recessed area 130. In the embodiments of the present application, the relationship between l and L can meet the requirements of stable installation of the nickel sheet 400 while facilitating the installation and disassembly of the nickel sheet 400.

[0068] In some embodiments, referring to Figure 8 , the support 100 at the bottom of the second recessed area 120 is provided with a positioning protrusion 160. The flexible circuit member 300 is provided with a positioning hole matched with the positioning protrusion 160. The positioning protrusion 160 can be a cylindrical protrusion, and correspondingly, the positioning hole is a circular through hole. The positioning protrusion 160 is arranged in the region close to the middle of the second recessed area 120. The number of the positioning protrusion 160 can be one or more.

[0069] In the embodiment of the application, during the assembly of the flexible circuit member 300, the positioning protrusion 160 is arranged on the support 100 to perform assembly positioning, so that it is quickly determined whether the flexible circuit member 300 is assembled in place, and the assembly speed of the flexible circuit member 300 is improved. In addition, the positioning protrusion 160 can also limit the movement of the flexible circuit member 300, reduce the probability of the occurrence of the misconnection of the nickel sheet 400 due to the movement of the flexible circuit member 300, and improve the circuit reliability.

[0070] In some embodiments, referring to ​ , the support 100, the first elastic sheet 140 and the second elastic sheet 150 are integrally formed. For example, the support 100, the first elastic sheet 140 and the second elastic sheet 150 are integrally formed by an injection molding process, which is convenient for processing and molding. In addition, the first elastic sheet 140 and the second elastic sheet 150 are stably connected with the support 100, and the stability of the overall structure of the CCS assembly 10 is improved.

[0071] In some embodiments, referring to ​ , the support 100 is provided with a first through hole 170, and the first through hole 170 is arranged in position with the first elastic sheet 140.

[0072] In some embodiments, referring to ​ , the support 100 is provided with a second through hole 180, and the second through hole 180 is arranged in position with the second elastic sheet 150.

[0073] The projection of the first elastic sheet 140 on the support 100 is located in the first through hole 170, and the projection of the second elastic sheet 150 on the support 100 is located in the second through hole 180. The first through hole 170 and the second through hole 180 serve as a recess for avoiding, which is convenient for processing the first elastic sheet 140 and the second elastic sheet 150. In addition, the first through hole 170 and the second through hole 180 provide an avoiding space for the deformation of the flexible circuit member 300 and the nickel sheet 400, and protect the flexible circuit member 300 and the nickel sheet 400.

[0074] The embodiment of the application also provides a battery module, which comprises the CCS assembly 10 of any one of the above embodiments and a battery cell. The battery module has the same technical effects as the CCS assembly 10, and thus the description is not repeated.
