[0039] Specifically, the first surface 101 and the second surface 102 can be the surfaces on the upper and lower sides of the connector 1, or the surfaces on the left and right sides of the connector 1. The shell can be a complete shell or a shell formed by two or more parts. A first chamber is formed between the first surface 101 and the shell, and a second chamber is formed between the second surface 102 and the shell. The first chamber and the second chamber are respectively suitable for accommodating electrical components, wherein the electrical components can be components in a battery pack BDU (Battery Drive Unit, battery pack circuit breaking unit) module, such as relays, current sensors, fuses, high and low voltage connectors, resistors, sealing rings, etc. The electrical components can also be components in a battery pack CCS (Cells Contact System, integrated busbar) module, such as a bus, a flexible circuit board, etc. It can also be a component in a battery pack PCM (Protection Circuit Module, current protection) module, and the specific type is not limited in the embodiments of the present application.

[0040] Thus, different electrical components can be installed through the first chamber and the second chamber formed between the connector 1 and the shell, which helps to reduce the difficulty of installing the electrical components in the battery pack. At the same time, the first chamber and the second chamber are close to each other, which helps to improve the integration of multiple electrical components and facilitates the management and maintenance of multiple electrical components.

[0041] Furthermore, the first surface 101 is provided with a first mounting portion, and the second surface 102 is provided with a second mounting portion, and the first mounting portion and the second mounting portion are respectively suitable for mounting electrical components.

[0042] Specifically, the electrical components in the first chamber are mounted on the first mounting portion, and the electrical components in the second chamber are mounted on the second mounting portion, that is, multiple electrical components are respectively mounted on different surfaces of the connector 1, and the integration of multiple electrical components is achieved through the connector 1, which further improves the integration of multiple electrical components and makes it easier to install and fix multiple electrical components. The first mounting portion and the second mounting portion can be threaded holes, clamping structures, grooves, welding points, etc., and the specific types are not limited in the embodiments of this application.

[0043] Further, see Figure 1 , Figure 2 and Figure 6 The connecting member 1 includes a substrate 11 and a side plate 12. The side plate 12 is arranged around the substrate 11 and is fixedly connected to the substrate 11. The first surface 101 and the second surface 102 are arranged opposite to each other along the thickness direction of the substrate 11, and a partial second chamber is enclosed between the second surface 102 and the side plate 12.

[0044] Specifically, the side panels 12 are arranged around the substrate 11 and are fixedly connected to the substrate 11, wherein the connector 1 can be processed into an integral part by an integrated molding process, and the substrate 11 and the side panels 12 are different parts of the connector 1, or the connector 1 can also be assembled and connected by independent parts, and the substrate 11 and the side panels 12 are assembled and connected together by fasteners such as bolts and screws, or are welded together by laser welding, thereby forming a complete connector 1. In addition, the side panels 12 are arranged around the substrate 11, and the side panels 12 can only extend from the upper surface or the lower surface of the substrate 11, so that the side panels 12 are arranged on one side of the substrate 11, and the side panels 12 can also extend from the upper surface and the lower surface of the substrate 11, so that the side panels 12 are arranged on both sides of the substrate 11. Among them, the upper surface and the lower surface of the substrate 11 are arranged relatively to each other along the thickness direction of the substrate 11, the upper surface of the substrate 11 forms the first surface 101 of the connector 1, and the lower surface of the substrate 11 forms the second surface 102 of the connector 1. The second surface 102 and the side plate 12 enclose a partial second chamber, and a connecting structure is provided on the side plate 12, which is fixedly connected to the shell through the connecting structure, thereby realizing a fixed connection between the connector 1 and the shell.

[0045] Further, see Figure 1 and Figure 2 The shell includes a bottom shell 5 , which is fixedly connected to the side plate 12 , and a second chamber is formed between the second surface 102 , the side plate 12 and the bottom shell 5 .

[0046] Specifically, the bottom shell 5 is fixedly connected to the side plate 12, and the fixed connection method includes but is not limited to fastener assembly connection, clamping, etc. A second chamber is formed between the second surface 102, the side plate 12 and the bottom shell 5, wherein a closed second chamber can be formed between the substrate 11, the side plate 12 and the bottom shell 5, thereby achieving a certain waterproof and dustproof effect on the electrical components in the second chamber. Figure 2 In some embodiments, the insulating bracket in the CCS module can be directly used as the bottom shell 5. If the insulating bracket serves as the bottom shell 5, the second chamber can be provided with electrical components such as the busbar 2 and the flexible circuit board 6. The insulating bracket is made of materials with good insulation properties such as epoxy resin, polycarbonate, plastic, and composite materials, which can achieve electrical insulation of the busbar 2 and the flexible circuit board 6 and reduce the risk of short circuit. In addition, if the insulating bracket is used as the bottom shell 5, it will help improve the integration of the CCS module with other modules and be more conducive to the optimization and improvement of the battery pack structure.

[0047] Further, see Figure 2 A clamping member 51 is provided on the bottom shell 5 , and a clamping hole 16 is provided on the side plate 12 . The clamping member 51 is clamped in the clamping hole 16 to clamp and fix the bottom shell 5 and the side plate 12 .

[0048] Specifically, the clamping hole 16 is provided on the side plate 12, and specifically can be provided on two opposite side plates 12. Correspondingly, the clamping member 51 is provided on two opposite sides of the bottom shell 5. The clamping member 51 is arranged along the direction toward the base plate 11. The size of the clamping member 51 is determined according to the size of the clamping hole 16, and it is sufficient to ensure that the clamping member 51 can be effectively clamped in the clamping hole 16. The number of the clamping hole 16 and the clamping member 51 can be one, two or more, and each clamping hole 16 is clamped with a clamping member 51. In the case where the number of the clamping holes 16 and the clamping members 51 is multiple, the multiple clamping holes 16 are evenly arranged on the side plate 12, and the multiple clamping members 51 are evenly arranged along the edge of the bottom shell 5, so as to improve the reliability and stability of the detachable connection between the base shell 1 and the bottom shell 5.

[0049] In addition, the clamping member 51 can be a component independent of the bottom shell 5, and is fixedly connected to the bottom shell 5 by fastener assembly connection, adhesive connection, or position-limiting clamping connection, which makes it easier to process the clamping member 51 and the bottom shell 5, and reduces the processing difficulty of the clamping member 51 and the bottom shell 5. The clamping member 51 and the bottom shell 5 can also be processed into an integral part through an integral molding process, which can save subsequent connection steps, help save the production cost of the bottom shell 5, and also help improve the connection reliability of the clamping member 51 and the bottom shell 5.

[0050] Further, see Figures 3 to 5 The shell includes a cover shell 7 , which is fixedly connected to the side plate 12 , and a first chamber is formed between the first surface 101 and the cover shell 7 .

[0051] Specifically, the cover shell 7 is fixedly connected to the side panel 12, and the fixed connection methods include but are not limited to fastener assembly connection, clamping, etc. The cover shell 7 can be made of plastic, composite materials, etc. to meet its functional requirements such as insulation, heat and high temperature resistance, stability, and dustproofness. After the cover shell 7 is fixedly connected to the side panel 12, a closed first chamber is formed between the first surface 101 of the substrate 11 and the cover shell 7, which can have a certain waterproof and dustproof effect on the electrical components in the first chamber. In some embodiments, the shell of the BDU module can be directly used as the cover shell 7. If the shell of the BDU module serves as the cover shell 7, electrical components such as relays, current sensors, fuses, high and low voltage connectors, etc. can be set in the first chamber. Figure 1 The cover 7 is made of a material with good insulation performance, which can achieve electrical insulation of the electrical components and reduce the risk of short circuit. In addition, if the shell of the BDU module serves as the cover 7, it will help improve the integration of the BDU module with other modules and be more conducive to the optimization and improvement of the battery pack structure.

[0052] When the shell of the BDU module is used as the cover 7 and the insulating bracket in the CCS module is used as the bottom shell 5, high-voltage control components such as relays, current sensors, fuses, high and low voltage connectors, etc. can be provided in the first chamber to form a complete BDU module, and busbar components such as busbars and flexible circuit boards can be provided in the second chamber to form a complete CCS module, thereby realizing the integration of the BDU module and the CCS module through the connector 1, effectively reducing the difficulty of installing and arranging the BDU module and the CCS module.

[0053] Further, see Figure 3 and Figure 4 The cover shell 7 is provided with a first buckling portion 71, and the side plate 12 is provided with a second buckling portion 17. The first buckling portion 71 and the second buckling portion 17 are buckled with each other to detachably connect the cover shell 7 and the side plate 12.

[0054] Specifically, the first buckle 71 is a buckle, and the second buckle 17 is a convex block. The buckle is arranged on the side of the cover shell 7 close to the substrate 11, and the convex block is arranged in the buckle to buckle and fix the cover shell 7 and the side plate 12. Of course, the first buckle 71 and the second buckle 17 can also be other structures that can buckle with each other, which is not limited in this embodiment. The cover shell 7 and the side plate 12 are buckled and fixed by the first buckle 71 and the second buckle 17, so as to realize the detachable connection between the cover shell 7 and the connecting member 1, which is convenient for the inspection and maintenance of the electrical components in the first chamber. The number of the first buckle 71 and the second buckle 17 can be one, two or more, which is determined according to the size and connection requirements of the cover shell 7 and the side plate 12, which is not limited in this embodiment. In addition, in the embodiment of the present invention, the cover shell 7 and the side plate 12 are detachably connected together through the buckle structure, which is also convenient for the disassembly and separation of the cover shell 7 and the connecting member 1, so as to facilitate the inspection and maintenance of the electrical components in the first chamber.

[0055] Further, see Figure 6 and Figure 7 The second surface 102 is provided with a plurality of vertical plates 13, which extend in a direction parallel to the side plates 12; some of the vertical plates 13 are connected to each other to form an accommodating cavity 10, and some of the vertical plates 13 are connected to the side plates 12 to form an accommodating cavity 10, and the accommodating cavity 10 forms a second mounting portion.

[0056] Specifically, the second surface 102 of the substrate 11 is provided with a plurality of vertical plates 13, which extend in a direction perpendicular to the substrate 11, and are arranged in an orderly manner on the second surface 102. Some of the vertical plates 13 are connected to each other to form a receiving cavity 10, and some of the vertical plates 13 are connected to the side plates 12 to form a receiving cavity 10. Figure 6On the connector 1 shown, every four vertical plates 13 enclose a rectangular or square accommodating cavity 10, and near the edge of the second surface 102, every three vertical plates 13 and the side plates 12 enclose a rectangular or square accommodating cavity 10. It should be noted that the connection between the vertical plates 13 and the vertical plates 13 or between the vertical plates and the side plates 12 can be connected by fastener assembly, laser welding, adhesive connection or clamping, which is not limited in the embodiment of the present invention.

[0057] In an embodiment of the present invention, the surface of the vertical plate 13 close to the accommodating cavity 10 can be set to a rough surface, and the electrical component is accommodated in the accommodating cavity 10. The electrical component is fixed by the friction between it and the surface of the vertical plate 13. A limiting groove can also be set on the surface of the vertical plate 13 close to the accommodating cavity 10, and the electrical component is clamped in the limiting groove to fix the electrical component. The specific method is not limited in the embodiment of the present invention.

[0058] Furthermore, Figure 7 An enlarged schematic diagram of the accommodating cavity 10 is shown, referring to Figure 7 In some embodiments of the present invention, a hook 131 is provided on a portion of the vertical plate 13 of each accommodating cavity 10, and the hook 131 is provided at the end of the vertical plate 13 away from the second surface 102, and the hook 131 extends in a direction toward the accommodating cavity 10, and the hook 131 is suitable for clamping and fixing the electrical component.

[0059] Specifically, the hook 131 and the vertical plate 13 can be processed into an integral part through an integral molding process, and the hook 131 and the vertical plate 13 can also be fixedly connected together by fastener assembly connection, welding, adhesive connection, etc. The hook 131 extends in the direction toward the accommodating cavity 10, that is, the hook 131 extends in the direction toward the center of the accommodating cavity 10. After the electrical component is inserted into the accommodating cavity 10, the bottom surface of the electrical component contacts the surface of the hook 131, and the hook 131 limits the electrical component in the height direction, thereby fixing the electrical component in the accommodating cavity 10. The height direction refers to the direction perpendicular to the base plate 11, or the direction parallel to the side plate 12 and the vertical plate 13.

[0060] In some embodiments, the surface of the hook 131 close to the accommodating cavity 10 has a slope, which is inclined toward the accommodating cavity 10. The existence of the slope helps to smoothly insert the electrical component into the accommodating cavity 10 and avoid jamming during the insertion process.

[0061] For each accommodating cavity 10, the number of hooks 131 can be one, two or more. If the number of hooks 131 is two, the two hooks 131 can be arranged on two oppositely arranged vertical plates 13. If the number of hooks 131 is four, each vertical plate 13 can be provided with a hook 131. If the number of hooks 131 is multiple, two or more hooks 131 can be provided on the vertical plate 13 with a longer length to improve the reliability of the hooks 131 in fixing the electrical components.

[0062] Further, see Figure 7 In some embodiments of the present invention, a hollow portion 132 is provided on a portion of the vertical plate 13 of each accommodating cavity 10, wherein the hollow portion 132 can be provided on the vertical plate 13 with the hook 131 at the end, or can be provided on the vertical plate 13 without the hook 131. Figure 7 In the accommodating cavity 10 shown in the figure, a hollow portion 132 is provided on the vertical plate 13 with a hook 131 at the end thereof. The hollow portion 132 helps to reduce the strength and stiffness of the vertical plate 13, thereby improving the deformation capacity of the vertical plate 13 and the hook 131, and further helps to smoothly clamp the electrical components.

[0063] The shape of the hollow portion 132 can be any shape such as rectangle, square, circle, etc. In the embodiment of the present invention, the hollow portion 132 is set as an opening arranged along the extension direction of the vertical plate 13. The number of openings can be one, two or more. The more openings there are, the lower the strength and stiffness of the vertical plate 13 will be, and the stronger the deformation ability will be, which is more conducive to the smooth insertion of electrical components, but the restraining ability of electrical components will be weakened accordingly; the fewer openings there are, the higher the strength and stiffness of the vertical plate 13 will be, and the weaker the deformation ability will be, and the restraining ability of electrical components will be enhanced accordingly, but the difficulty of inserting electrical components will increase accordingly.

[0064] Further, see Figure 6 In some embodiments of the present invention, a plurality of accommodating cavities 10 are arranged in parallel on the second surface 102; and / or, the accommodating cavities 10 are rectangular structures.

[0065] Specifically, Figure 6 It is shown that a plurality of accommodating cavities 10 on the second surface 102 are arranged in two rows, wherein one row has five accommodating cavities 10 and the other row has four accommodating cavities 10. The specific arrangement of the accommodating cavities 10 can be set according to the number of accommodating cavities 10 and the size of the substrate 11, and this embodiment of the present invention is not limited to this.

[0066] Alternatively, each accommodating cavity 10 may be configured as a rectangular structure to better adapt to the structural shape of the electrical component and facilitate the arrangement of multiple accommodating cavities 10 in the connector 1. Of course, multiple rectangular accommodating cavities 10 may also be arranged side by side on the second surface 102.

[0067] Further, see Figure 1 and Figure 2 In some embodiments of the present invention, a first through hole 14 and an adapter 3 are further provided on the first surface 101; the first through hole 14 penetrates the substrate 11 along the thickness direction of the substrate 11, and the first through hole 14 is suitable for allowing the electrical components located in the second chamber to pass through and connect with the adapter 3.

[0068] Specifically, if Figure 2 As shown, taking the busbar 2 as an example, the end of the busbar 2 extends along the thickness direction of the substrate 11 to form a bent portion, the first through hole 14 is provided on the peripheral side of the adapter 3, and penetrates the substrate 11 along the thickness direction of the substrate 11, the bent portion of the busbar 2 is penetrated in the first through hole 14, and passes through the first through hole 14 to connect with the adapter 3. The adapter 3 is used to realize the electrical connection between the busbar 2 and the electrical components in the first chamber. Specifically, the adapter 3 can play a role of mechanical fixing. For example, the electrical components in the first chamber have copper bus terminals, and the busbar 2 and the copper bus are both overlapped on the adapter column 3. The adapter column 3 plays a role of mechanical fixing on the busbar 2 and the copper bus, so that the busbar 2 and the copper bus are in electrical contact, so that current can be transmitted between the busbar 2 and the copper bus, thereby realizing communication between the electrical components in the first chamber and the electrical components in the second chamber. Of course, the electrical components that can establish communication with the adapter 3 include but are not limited to the bus 2, wherein the adapter 3 can be made of plastic or other non-metallic materials. The adapter 3 itself does not have the ability to conduct electricity, but only plays the role of overlapping and fixing the electrical components and the copper bus. The surfaces of the electrical components and the copper bus are in contact with each other to achieve electrical connection between them.

[0069] like Figure 2 The end of the middle bus 2 extends along the thickness direction of the substrate 11 to form two bent portions, so two adapters 3 are provided on the first surface 101, and the two adapters 3 are both provided at the edge of the substrate 11. A first through hole 14 is provided on the circumferential side of each adapter 3, and the two bent portions are respectively penetrated into the two first through holes 14 and connected to the corresponding adapters 3.

[0070] Further, see Figure 2 In some embodiments of the present invention, a second through hole 15 is further provided on the substrate 11, and the second through hole 15 penetrates the substrate 11 along the thickness direction of the substrate 11; the second through hole 15 is suitable for fasteners to pass through to fix the electrical components located in the second chamber.

[0071] Specifically, since there are multiple electrical components in the second chamber, there can also be multiple second through holes 15 to effectively fix the electrical components. The multiple second through holes 15 are arranged in an array on the substrate 11 and penetrate the substrate 11 in the thickness direction of the substrate 11. Figure 2, it is shown that several second through holes 15 are arranged in two rows and multiple columns on the substrate 11. Correspondingly, several third through holes 21 are also provided on the electrical components in the second chamber, and the third through holes 21 penetrate the electrical components along the thickness direction of the substrate 11, and the number of the third through holes 21 can meet the fixing requirements of several electrical components. Each second through hole 15 is coaxially arranged with a third through hole 21, that is, the centers of the second through hole 15 and the third through hole 21 are located on the same straight line, and the second through hole 15 and the third through hole 21 can be any shape such as a circular hole, an elliptical hole, a square hole, etc. If the second through hole 15 and the third through hole 21 are circular holes, the centers of the second through hole 15 and the third through hole 21 are respectively the centers of their circles, and if the second through hole 15 and the third through hole 21 are square holes, the centers of the second through hole 15 and the third through hole 21 are respectively the intersections of their diagonals.

[0072] like Figure 5 As shown, the fastener 4 can be a bolt or the like, and there are also a plurality of fasteners 4, each fastener 4 passes through a second through hole 15 and is inserted into the corresponding third through hole 21 to fix the electrical component. In addition, the size of the second through hole 15 can be slightly larger than the size of the third through hole 21 to ensure that the fastener 4 can smoothly pass through the second through hole 15 and enter the third through hole 21.

[0073] In addition, since heat is generated when current flows through the electrical component, the second through hole 15, in addition to allowing the fastener 4 to pass through, can also serve as a heat dissipation hole to dissipate the heat generated by the electrical component, thereby dissipating the heat of the electrical component, helping to reduce the temperature of the electrical component and ensure the normal operation of the electrical component.

[0074] Further, see Figure 2 In some embodiments of the present invention, the first through holes 14 are arranged at the edge of the substrate 11 along its length direction, and the second through holes 15 are evenly arranged along the length direction of the substrate 11 to avoid interference between the first through holes 14 and the second through holes 15, which also helps the operator to accurately distinguish the first through holes 14 and the second through holes 15 during the assembly process of the module.

[0075] In an embodiment of the present invention, the first through hole 14 and the second through hole 15 are of different shapes. The shape of the first through hole 14 is adapted to the shape of the electrical component, and a strip-shaped hole is used to facilitate the end of the electrical component to pass through smoothly and connect with the adapter 3; the shape of the second through hole 15 is adapted to the shape of the fastener 4, and a circular hole is used to facilitate the fastener 4 to pass through smoothly and be inserted into the third through hole 21 on the electrical component.

[0076] At the same time, if Figure 2As shown, since the first through hole 14 is only used to allow the end of the electrical component to pass through, and the second through hole 15 needs to allow multiple fasteners 4 to pass through to achieve the connection of multiple electrical components, the number of first through holes 14 is much less than the number of second through holes 15. The specific number depends on the number of electrical components and connection requirements, which is not limited by this embodiment of the present invention.

[0077] Further, see Figure 2 and Figure 5 When the bottom shell 5 is an insulating support in the CCS module, the insulating support 5 is provided with a plurality of fourth through holes 52, which are arranged in an array on the insulating support 5 and penetrate the insulating support 5 along the thickness direction of the substrate 11. The fourth through hole 52 is coaxially arranged with the third through hole 21. Since the third through hole 21 is coaxially arranged with the second through hole 15, it is equivalent to coaxially arranging the second through hole 15, the third through hole 21 and the fourth through hole 52, that is, the centers of the second through hole 15, the third through hole 21 and the fourth through hole 52 are located on the same straight line. A plurality of fasteners 4 pass through the second through hole 15 and are respectively arranged in the corresponding third through hole 21 and the fourth through hole 52 to achieve the fixing of the electrical components and the insulating support 5.

[0078] Further, see Figure 2 The electrical components in the second chamber include a flexible circuit board 6, which is a part of the CCS module. The flexible circuit board 6 is a circuit board made of a flexible copper-clad laminate as a substrate. As a medium for signal transmission, the flexible circuit board 6 is arranged between the electrical component and the insulating bracket 5. A connecting piece is arranged on the edge of the flexible circuit board 6, and the flexible circuit board 6 is fixedly connected to the electrical component through the connecting piece. The connecting piece can be fixed to the flexible circuit board 6 by laser welding, adhesive connection, etc. The connecting piece has good electrical conductivity, such as a metal sheet, etc., and the electrical connection between the electrical component and the flexible circuit board 6 can be achieved through the connecting piece.

[0079] At the same time, the flexible circuit board 6 also has good electrical insulation and chemical corrosion resistance, which can ensure the safe operation of the circuit. A fuse protection current design can be added to the flexible circuit board 6. In the case of a short circuit in the battery pack, the circuit is directly melted by the fuse protection, thereby avoiding problems such as fire and explosion of the battery pack.

[0080] An embodiment of the present invention further provides a battery pack, comprising a battery cell and the integrated control module described in any one of the aforementioned embodiments, wherein the integrated control module is electrically connected to the battery cell and is suitable for controlling the operation of the battery cell.

[0081] Specifically, the battery pack includes a plurality of cells, which are connected in series or in parallel to form a battery pack. The battery pack and the integrated control module are both arranged in the box of the battery pack. The integrated control module is electrically connected to the battery pack and is used to monitor and adjust the working state of the battery pack to ensure the normal execution of the charging and discharging functions of the battery pack. The integrated control module occupies less space in the box, which helps to reduce the difficulty of installing and arranging the integrated control module in the box, thereby reducing the difficulty of preparing the battery pack and saving the preparation cost of the battery pack.

[0082] The embodiment of the present invention further provides a vehicle, comprising the battery pack described in the above embodiment. The vehicle may be a pure electric vehicle or a hybrid vehicle, and the vehicle comprising the battery pack described in the above embodiment helps to control the manufacturing cost of the vehicle.
