[0032] The first embodiment

[0033] Please refer to Figure 1 , this embodiment provides a copper busbar connection bracket 100, which includes a bracket body 10 and a fixing plug. An installation plane 14 is provided on the bracket body 10. A copper busbar connector 11 is provided on the installation plane 14. The copper busbar connector 11 is used to fix the copper busbar 202 on the installation plane 14.

[0034] Specifically, in this embodiment, the bracket body 10 is a columnar structure. The top surface of the bracket body 10 is the installation plane 14. The bottom surface of the bracket body 10 is spaced from the installation plane 14 by a certain height. It can be understood that when the bracket body 10 is installed on the battery pack 200, the bottom surface of the bracket body 10 abuts against the battery pack 200. Thus, when the copper busbar 202 is fixed on the installation plane 14, the copper busbar 202 can be supported at a certain height relative to the battery pack 200.

[0035] Optionally, in this embodiment, the bracket body 10 is a rectangular columnar structure. In other embodiments, the bracket body 10 can be a cylindrical structure. The present invention does not limit the shape of the bracket body 10.

[0036] The fixing plugs are arranged on both sides of the bracket body 10. The fixing plugs are used to fix the bracket body 10. It can be understood that when it is necessary to fix the bracket body 10, the bracket body 10 is moved in the direction close to the battery pack 200, so that the fixing plugs are inserted into the corresponding fixing structures of the battery pack 200. It can be understood that in this embodiment, slots can be provided on the battery pack 200, and the fixing plugs can be inserted into the slots to fix the bracket body 10 on the battery pack 200. The fixing plugs in this embodiment are arranged along the installation direction of the bracket body 10, reducing the space occupied on the side of the bracket body 10, reducing the overall volume of the fixing of the copper row connecting bracket 100 and the battery pack 200, and being able to reduce the space occupied by the battery pack 200.

[0037] Please refer to Figure 1 and Figure 2 , specifically, in this embodiment, the fixing plug is a buckle 20. The buckle 20 is arranged on both sides of the bracket body 10 and extends in the direction away from the installation plane 14. Further, one end of the buckle 20 is connected to the bracket body 10, and the other end of the buckle 20 extends out of the bottom surface of the bracket body 10, so that when the bottom surface of the bracket body 10 abuts against the battery pack 200, the buckle 20 can be inserted into the battery pack 200.

[0038] Further, a barb 21 is provided at the end of the buckle 20 away from the bracket body 10. It can be understood that when the bracket body 10 is fixed on the battery pack 200, the barb 21 can abut against the inner wall structure of the battery pack 200, so as to prevent the bracket body 10 from disconnecting from the battery pack 200.

[0039] Furthermore, the buckle 20 is inclined towards the outside of the bracket body 10. It can be understood that when the bracket body 10 is fixed on the battery pack 200, the buckle 20 is inclined. When the battery pack 200 shakes, while the bracket body 10 moves outwards, the buckle 20 abuts against the battery pack 200, preventing the bracket body 10 from being thrown out and disconnecting from the battery pack 200.

[0040] In this embodiment, the buckle 20 is a spring piece. It can be understood that when it is necessary to install the bracket body 10 on the battery pack 200, the buckle 20 on both sides of the bracket body 10 is clamped to make the buckle 20 contract towards the bracket body 10. When the bracket body 10 is installed on the battery pack 200, the buckle 20 is inserted into the battery pack 200, and the buckle 20 is released. The buckle 20 rebounds and abuts against the battery pack 200, thereby fixing the bracket body 10 on the battery pack 200.

[0041] In other embodiments, an elastic member can also be provided between the bracket body 10 and the buckle 20, so that the buckle 20 can elastically deform relative to the bracket body 10, which can provide a supporting force for the buckle 20 to fix the bracket body 10. Specifically, the elastic member can be a spring.

[0042] Please refer to Figure 1 and Figure 3 , a limiting column 12 is also provided on the bracket body 10. The limiting column 12 is fixedly connected to the side of the bracket body 10 away from the mounting plane 14. Specifically, the limiting column 12 is fixed on the bottom surface of the bracket body 10. In this embodiment, the limiting column 12 extends beyond the bottom surface of the bracket body 10 by a certain distance. It can be understood that when the bracket body 10 is installed on the battery pack 200, the bottom surface of the bracket body 10 abuts against the outer wall of the battery pack 200. The limiting column 12 is inserted into the battery pack 200. An opening corresponding to the limiting column 12 is provided on the battery pack 200. The limiting column 12 is provided to further fix the bracket body 10 and the battery pack 200, and can also keep the relative position of the fixed bracket and the battery pack 200 fixed. In order to prevent the fixed bracket and the battery pack 200 from rotating relative to each other, in this embodiment, the limiting column 12 is a square column structure.

[0043] Furthermore, the limiting column 12 is provided at the copper busbar connector 11. Specifically, the copper busbar connector 11 is located at the mounting plane 14. The limiting column 12 is located at a position on the bottom surface corresponding to the copper busbar connector 11. In this embodiment, the copper busbar connector 11 is a rivet nut. The rivet nut is embedded in the limiting column 12. It can be understood that in order to install the copper busbar 202 on the mounting plane 14 and fit with the mounting plane 14, the threaded structure of the rivet nut needs to be embedded under the mounting plane 14. Embedding the rivet nut in the limiting column 12 below can further reduce the space occupied by the copper busbar 202 connection structure and the battery pack 200.

[0044] Please refer to Figure 1 In this embodiment, a plurality of protective columns 13 are further provided on the mounting plane 14. The protective columns 13 are spaced apart at the edge of the mounting plane 14. Specifically, in this embodiment, the mounting plane 14 is a square plane. There are four protective columns 13, which are respectively provided at the four corners of the mounting plane 14. A clearance groove is formed between the protective columns 13. The height of the protective columns 13 is greater than the thickness of the copper busbar 202. It can be understood that the height of the protective column 13 refers to the distance from one end of the protective column 13 away from the mounting plane 14 to the mounting plane 14. When the copper busbar 202 needs to be installed on the mounting plane 14, the copper busbar 202 passes through the clearance groove, is located between the two protective columns 13, and is fixed to the copper busbar 202 fixing piece by bolts.

[0045] Second embodiment

[0046] Please refer to Figure 4, this embodiment provides a battery pack 200, which includes a shell 201, a copper busbar 202 and the copper busbar connecting bracket 100 provided in the above-mentioned first embodiment. The copper busbar connecting bracket 100 is fixed to the shell 201 through a fixing plug-in. Specifically, in this embodiment, a slot and a limit groove (not shown) are provided on the shell 201. The fixing plug-in is used to cooperate with the slot, and the buckle 20 is inserted into the slot to fix the bracket body 10 to the shell 201, and the barb 21 at the end of the buckle 20 abuts the inner wall of the shell 201. The limiting column 12 is used to cooperate with the limiting groove, and the limiting column 12 is inserted into the limiting groove. It can be understood that when the bottom surface of the bracket body 10 abuts the shell 201, the length of the buckle 20 can satisfy that the barb 21 just abuts the inner wall of the shell 201.

[0047] Furthermore, the copper busbar 202 is fixed to the mounting plane 14. In this embodiment, the copper busbar 202 includes a busbar body 2022 and a connecting portion 2021. The connecting portion 2021 is bent relative to the busbar body 2022, meaning that the connecting portion 2021 and the busbar body 2022 are located on two planes spaced apart. The connecting portion 2021 is fixed to the mounting plane 14. The busbar body 2022 is bent toward the side of the battery pack 200.

[0048] The copper busbar connection bracket 100 of the battery pack 200 provided in this embodiment has the following beneficial effects:

[0049] The copper busbar connecting bracket 100 of the battery pack 200 of the present invention includes a bracket body 10 and a fixing plug-in. A mounting plane 14 is provided on the bracket body 10. A copper busbar connector 11 is provided on the mounting plane 14. The copper busbar connector 11 is used to fix the copper busbar 202 on the mounting plane 14. The fixing plug-in is provided on both sides of the bracket body 10.
