[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference below Figure 1-Figure 12 A busbar support assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0041] like Figure 3-Figure 10 As shown, the busbar support assembly 100 according to the first embodiment of the utility model includes: a busbar support 10 , a plurality of busbars 20 and a flexible circuit board 30 .

[0042] Specifically, multiple bus bars 20 are arranged on a bus bar bracket 10, and a reinforcing flange 11 is formed on at least one side of the bus bar bracket 10 in the width direction. The bus bar bracket 10 is provided with a mounting plate portion 12 at one end in the length direction. The flexible circuit board 30 includes a circuit board body 31 and a connector 32. The circuit board body 31 is arranged on the bus bar bracket 10, and the connector 32 is connected to the circuit board body 31 and fixed on the mounting plate portion 12.

[0043] That is, the busbar support 10 may be formed with the reinforcing flange 11 on one side in the width direction, or the busbar support 10 may be formed with the reinforcing flange 11 on both sides in the width direction.

[0044] It is understandable that when the bus bracket 10 is too long, the force acting on the bus bracket 10 will generate a large torque, making the bus bracket 10 easy to break. In this embodiment, by providing a reinforcing flange 11 on at least one side of the bus bracket 10 in the width direction, the supporting strength of the bus bracket 10 can be increased and the probability of damage to the bus bracket 10 during use can be reduced.

[0045] The connector 32 is used to connect to the battery management system. After the battery module 1000 is assembled, the connector 32 needs to be fixed to prevent the connector 32 from shaking during use, which may cause the connection between the connector 32 and the battery management system to fail.

[0046] In this embodiment, by setting a mounting plate portion 12 at one end of the bus bracket 10, the connector 32 can be fixed on the mounting plate portion 12. In this way, there is no need to set an additional bracket to fix the connector 32 during the assembly process, which can improve the integration of the bus bracket 10. During the assembly process, the mounting plate portion 12 can be assembled to the battery module 1000 together with the bus bracket 10, thereby reducing the operating steps and improving the assembly efficiency.

[0047] According to the bus bracket assembly 100 of the first aspect of the utility model, the supporting strength of the bus bracket 10 can be improved by providing a reinforcing flange 11, and the integration of the bus bracket assembly 100 can be improved by fixing the connector 32 on the mounting plate portion 12. The operation steps can be reduced during the assembly process, thereby improving the assembly efficiency.

[0048] In some embodiments of the present invention, Figure 5 and Figure 6As shown, in the width direction of the busbar support 10, the busbar support 10 includes a first section 13, a second section 14 and a third section 15 which are connected in sequence, and the first section 13 and the third section 15 are arranged at intervals in the thickness direction of the busbar support 10. Thus, the support strength of the busbar support 10 can be further improved, and in the process of product design, the parameters such as the size and relative angle of the first section 13, the second section 14 and the third section 15 can be adjusted to meet more product design needs.

[0049] In some embodiments of the present invention, Figure 6 As shown, the busbar support 10 is formed with reinforcing flanges 11 on both sides in the width direction, and the two reinforcing flanges 11 are respectively a first flange 111 and a second flange 112. In the thickness direction of the busbar support 10, the size of the first flange 111 is larger than the size of the second flange 112. Thus, the support strength of the busbar support 10 can be further improved. It can be understood that in the width direction of the busbar support 10, the side close to the busbar 20 is subjected to a larger force. In the process of product design, the first flange 111 can be arranged on the side of the busbar support 10 close to the busbar 20, so that the support strength of the busbar support 10 meets the use requirements, and at the same time, it can save production materials and reduce production costs.

By setting the expansion section 17, the plug-in connector 32 and the busbar 20 can be spaced apart. It can be understood that the temperature on the busbar 20 is relatively high, so that the probability of overheating of the plug-in connector 32 during the operation of the battery module 1000 can be reduced, thereby improving the reliability of the battery module 1000 during operation. In the process of product design, the size of the expansion section 17 and the busbar section 16 can be adjusted to meet more product design needs.

The mounting plate 12 moves relative to the expansion section 17 to drive the telescopic section 18 to telescope and deform. During the assembly process, the mounting plate 12 can be pushed to move according to the assembly space requirements, so that the mounting plate 12 and the connector 32 are adapted to the assembly space, thereby reducing the difficulty of assembly.

In this way, the operator does not need to use an additional fixing portion 43 to fix the connector 32 during riveting, thereby reducing the difficulty of operation. In addition, the riveting and bonding operations are convenient, which can improve production efficiency. The riveting connection has high strength and can meet the needs of use.

[0054] In some embodiments of the present invention, Figure 9-12 As shown, the busbar support assembly 100 also includes: an output pole seat 40, the output pole seat 40 is provided with a first plate portion 41 and a second plate portion 42 on both sides of the busbar support 10 in the length direction, the first plate portion 41 is connected to the mounting plate portion 12, and the plug-in connector 32 is fixed on the second plate portion 42. Among them, the output pole seat 40 is used to install the output pole busbar, and the output pole busbar is used to collect the current on multiple busbars 20 and output it to the outside. By installing the output pole seat 40 on the mounting plate portion 12 and fixing the plug-in connector 32 on the output pole seat 40, the integration of the busbar support assembly 100 can be further improved. During the assembly process, the output pole seat 40 and the plug-in connector 32 can be assembled to the battery module 1000 together with the busbar support assembly 100, so as to further improve the assembly efficiency.

During the assembly process, the output pole bus is placed on the fixing portion 43, and then the output pole bus is fixed to the fixing portion 43 through the fixing hole 431. In this way, the assembly method is relatively simple, wherein, preferably, the fixing hole 431 is a threaded hole, and the bolt passes through the through hole on the output pole bus to fix the output pole bus to the fixing portion 43.

[0056] The output pole seat 40 is also provided with a first support plate and a second support plate 44 arranged opposite to each other, the fixing portion 43 is arranged between the first support plate and the second support plate 44, a support hole 411 is formed on the first support plate facing the second support plate 44, and a clamping hole 441 is formed on the second support plate 44.

[0060] Reference below Figure 1-Figure 12 A battery module 1000 according to an embodiment of the second aspect of the present invention is described.

The first direction, the second direction and the third direction are perpendicular to each other.

[0063] Among them, a plurality of pole avoidance holes 19 are formed on the busbar bracket 10, and the busbar 20 is riveted on the busbar bracket 10 and passes through the pole avoidance holes 19 to be connected with the pole 210.
