[0002] The CCS integrated busbar (Cells Contact System) is a key component in the battery module, which integrates functions such as high-voltage series and parallel connection of battery cells, temperature sampling, voltage sampling, etc., and transmits this information to the battery management system (BMS) through a signal acquisition component. The composition of the CCS integrated busbar mainly includes a signal acquisition component (such as FPC, PCB, FFC, etc.), a plastic structural part, a copper-aluminum busbar, etc., and these components are connected into a whole through a thermal pressing or riveting process.
[0003] Currently, the busbar of CCS generally adopts a wire harness fixing method. As shown in Figure 1 shown, Figure 1 is a CCS bracket in the prior art, and its fixing and processing flow is as follows: the busbar is fixed on the plastic suction bracket through a thermal riveting process, then the sampling nickel sheet is fixed by laser welding, and finally the sampling wire harness is fixed on the plastic suction bracket by a tie strap. The above method has more processing procedures, low production efficiency, high fixture cost, and it is difficult to repair the above structure when the busbar has poor welding. Summary of the Utility Model
[0004] The utility model provides a CCS bracket, a CCS component and a battery module to solve the problem of high cost of the fixing method of the conductive bar of CCS in the prior art.
[0005] To solve the above technical problem, the technical solution adopted by the utility model is to provide a CCS bracket, and the CCS bracket includes: a substrate, positioning stud holes and riveting holes.
[0006] The substrate includes a mounting plate and a wiring board connected to each other. Among them, the mounting plate is provided with a plurality of mounting grooves and mounting posts for mounting the busbar at intervals in a first direction, and the mounting posts penetrate through the middle of the mounting grooves.
[0007] The positioning stud holes are arranged in the middle of the mounting posts; the riveting holes are located on the side of the mounting posts away from the wiring board in a second direction and are used for fixing blind rivets.
[0008] The beneficial effects brought by the technical solution provided by the utility model compared with the prior art are:
[0009] By adding riveting holes for fixing blind rivets on the installation posts, when installing the busbar through the installation groove and the installation posts, blind rivets can be used for fixing, greatly reducing the processing cost. Among them, a blind rivet refers to a fastener that relies on single-sided riveting. Furthermore, compared with the current methods of fixing by hot riveting, laser welding, and gluing, the blind rivet has strong detachability, which is convenient for subsequent maintenance of the busbar.
[0010] In addition, the installation posts are located in the middle of the installation groove, and the positioning post holes are located in the middle of the installation posts, making the fixation of the busbar more stable. Through the position design of the riveting holes and the positioning post holes, while simplifying the manufacturing process, the busbar can be effectively and accurately positioned and installed and fixed.

[0013] In some embodiments, the wire management groove includes a groove and an elastic piece. One end of the elastic piece is fixedly arranged on the wiring board, and the other end can deform and move away from or close to the wiring board, so that when the elastic piece deforms, a limiting space for accommodating the wire harness can be formed.
[0014] Adopting the above technical solution, by deforming the elastic piece to form a limiting space for accommodating the wire harness, the wire harness can be effectively limited, and by fixing the wire harness with the elastic piece, the use of cable ties can be reduced, thereby reducing the required operation time and further improving production efficiency.
[0015] In some embodiments, the wire management grooves are arranged in a staggered manner along the second direction.
[0016] Adopting the above technical solution, when the wire management grooves are arranged in a staggered manner, the corresponding elastic pieces are also arranged facing each other along the first direction. Therefore, when burying the wire harness, the wire harness can be limited along the first direction.
[0017] In some embodiments, a first reinforcing member is further convexly provided at the top of the elastic piece along the third direction.
[0018] Adopting the above technical solution, the first reinforcing member is added to enhance the structural strength of the elastic piece, thereby reducing the probability of the elastic piece breaking during deformation, enhancing the durability of the elastic piece and the pressing force on the wire harness.
[0019] In some embodiments, a plurality of second reinforcing members are further provided in the middle of the wire arrangement board, and the plurality of second reinforcing members are arranged at intervals along the first direction.
[0020] With the above technical solution, when a plurality of wire harnesses are aggregated into a main wire, they can be arranged and limited around the second reinforcing member, further reducing the usage amount of cable ties.
[0021] In some embodiments, the wire arrangement board further includes cable tie holes, and the cable tie holes are located on one side of the second reinforcing member along the first direction.
[0022] In some embodiments, the substrate further includes a groove. Among them, a transverse groove is provided on one side of the groove close to the mounting groove along the second direction, and a vertical groove communicating with the transverse groove is provided on the side away from the mounting groove. Among them, the grooves are arranged staggeredly along the second direction.
[0023] With the above technical solution, since the substrate is generally made of plastic by suction molding, by adding grooves to the wire arrangement board, the structural strength of the CCS bracket can be effectively improved.
[0024] In some embodiments, the present application further provides a CCS assembly, including the above CCS bracket, and further including a wiring terminal connected to the wiring hole of the CCS bracket. Among them, the wiring terminal is an internal tooth plum blossom type or an external tooth plum blossom type.
[0025] With the above technical solution, using an internal tooth plum blossom type or an external tooth plum blossom type wiring terminal to connect to the wiring hole can further reduce the usage amount of laser welding or screws, thereby facilitating subsequent maintenance.
[0026] In some embodiments, the present application further provides a battery module, including the above CCS assembly and battery cells, wherein the CCS assembly is connected to the battery cells. The CCS assembly is connected to the battery cell tabs one by one, thereby facilitating the acquisition of battery cell state information. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0038] Refer to Figures 2 to 3 as shown Figure 2 shows a schematic partial structure view of an embodiment of a CCS bracket provided by the present application; Figure 3 shows a top view of an embodiment of a CCS bracket provided by the present application.
[0039] In some implementation manners, the CCS bracket includes: a substrate 10, a positioning post hole 20, and a riveting hole 30. The substrate 10 includes a mounting plate 11 and a wiring strip board 12 that are connected to each other. Among them, the mounting plate 11 extends along a first direction ( Figure 3A plurality of mounting grooves 110 and mounting posts 111 for mounting the bus bar 60 are provided at intervals in the X direction shown in the figure, and the mounting post 111 penetrates through the middle of the mounting groove 110.
[0040] The positioning post hole 20 is arranged in the middle of the mounting post 111; the riveting hole 30 is located on the side of the mounting post 111 away from the wiring board 12 along the second direction ( Figure 3 the Y direction shown in the figure) and is used for fixing the blind rivet.
[0041] In the embodiment of the present application, by adding the riveting hole 30 for fixing the blind rivet on the mounting post 111, when the bus bar 60 is installed through the mounting groove 110 and the mounting post 111, the blind rivet can be used for fixing, greatly reducing the processing cost. Among them, the blind rivet refers to a fastener that relies on single-sided riveting. Furthermore, compared with Figure 1 the hot riveting fixing method shown in the figure, the blind rivet has strong detachability, which is convenient for subsequent maintenance of the bus bar 60.
[0042] In addition, the mounting post 111 is located in the middle of the mounting groove 110, and the positioning post hole 20 is located in the middle of the mounting post 111, which can effectively fix the bus bar 60 when the bus bar 60 is installed. Furthermore, through the position design of the riveting hole 30 and the positioning post hole 20, the processing technology can be effectively simplified.
[0043] In some embodiments, as shown in combination with Figures 1 to 2 the figure, a wiring hole 40 is further provided on the side of the mounting post 111 away from the riveting hole 30 along the second direction ( Figure 3 the Y direction shown in the figure), wherein the wiring board 12 further includes a plurality of wire management grooves 50 corresponding to the wiring holes 40, so that the wire harness 70 connected to the wiring hole 40 can be fixed in the wire management groove 50.
[0044] In the embodiment of the present application, arranging the wiring hole 40 on the mounting post 111 can facilitate the positioning and connection of the wire harness 70 and enable the wire harness 70 to be arranged along the wire management groove 50. Exemplarily, compared with Figure 1 arranging the connection position of the wire harness 70 on one side of the bus bar 60 in the figure, the wiring hole 40 located on the mounting post 111 can effectively reduce the risk of wiring detachment, thereby improving its connection stability.
[0045] See Figures 4 to 5 the figure shown, Figure 4 which shows a three-dimensional structural schematic diagram of an embodiment of a CCS bracket provided by the present application; Figure 5 which shows a partial structural schematic diagram of an embodiment of a wiring groove 51 of a CCS bracket provided by the present application.
[0046] In some embodiments, a plurality of second reinforcing members 120 are further provided in the middle of the flexible cable board 12, and the plurality of second reinforcing members 120 are arranged at intervals along the first direction ( Figure 3 as shown by the X direction in
[0047] . In the embodiment of the present application, when a plurality of wire harnesses 70 are aggregated into a main wire, they can be arranged and limited around the second reinforcing member 120, further reducing the usage amount of cable ties. The flexible cable board 12 further includes cable tie holes 121, and the cable tie holes 121 are located on one side of the second reinforcing member 120 along the first direction.
[0048] In some embodiments, the substrate 10 further includes a groove 13. Among them, a horizontal groove 130 is provided on one side of the groove 13 close to the mounting groove 110 along the second direction ( Figure 3 as shown by the Y direction in Figure 3 ), and a vertical groove 131 communicating with the horizontal groove 130 is provided on the side far from the mounting groove 110. Among them, the grooves 13 are arranged staggeredly along the second direction (
[0049] as shown by the Y direction in
[0050] . In the embodiment of the present application, since the substrate 10 is generally made of plastic by vacuum forming, by adding the groove 13 on the flexible cable board 12, the structural strength of the CCS bracket can be effectively improved. Exemplarily, the staggered arrangement of the grooves 13 makes the stress distribution of the substrate 10 more uniform.
[0051] In the embodiment of the present application, by deforming the elastic piece 52 to form a limiting space for accommodating the wire harness 70, the wire harness 70 can be effectively limited, and the use of cable ties is reduced, thereby reducing the required operation time and further improving the production efficiency. Exemplarily, as shown in Figure 5 , when the wire harness 70 extends along the wiring hole 40 to the wire management groove 50, the elastic piece 52 deforms to form a limiting space. After the wire harness 70 passes through the limiting space, the elastic piece 52 resets to press against the wire harness 70, thereby limiting it.
[0052] In some embodiments, the wire management groove 50 is arranged staggeredly along the second direction ( Figure 3 as shown by the Y direction in
[0053] . In the embodiment of the present application, when the wire management groove 50 is arranged staggeredly, the corresponding elastic pieces 52 are also arranged facing each other along the first direction ( Figure 3 as shown by the X direction in Figure 3 ). Therefore, when the wire harness 70 is buried, it can be limited along the first direction ( Figure 3 as shown by the X direction in ).
[0054] In some embodiments, a first reinforcing member 520 is further convexly provided on the top of the elastic piece 52 along the third direction ( Figure 7 as shown by the Z direction in the figure).
[0055] In the embodiment of the present application, the first reinforcing member 520 is added to enhance the structural strength of the elastic piece 52, thereby reducing the probability of the elastic piece 52 breaking during deformation, enhancing the durability of the elastic piece 52 and the pressing force on the wire harness 70.
[0056] See Figure 6 as shown in Figure 6 which shows a schematic perspective view of a terminal 80 with an external gear plum blossom shape of a CCS component provided by the present application.
[0057] In some embodiments, the present application further provides a CCS component, including the above-mentioned CCS bracket, and further including a terminal 80 connected to the wiring hole 40 of the CCS bracket, wherein the terminal 80 is of an internal gear plum blossom shape or an external gear plum blossom shape.
[0058] In the embodiment of the present application, the terminal 80 of the internal gear plum blossom shape or the external gear plum blossom shape is used to connect with the wiring hole 40, which can further reduce the usage amount of laser welding or screws, and further improve the connection stability when it is matched with the wiring hole 40, and is convenient for subsequent disassembly and maintenance.
