[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0033] Reference will be made below to the attached Figures 1-6 to describe the busbar support assembly 100 according to an embodiment of the present invention.

[0034] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , the busbar support assembly 100 according to an embodiment of the present invention includes: a support body 10, and a mounting hole 11 adapted for mounting the terminal post 200 is provided on the support body 10. The mounting hole 11 extends along the thickness direction of the support body 10 (such as Figure 1The up-and-down direction shown) penetrates through the bracket body 10, and a convex edge 112 is formed along the hole edge of the mounting hole 11, and the convex edge 112 protrudes in a direction away from the center of the mounting hole 11.

[0035] For example, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the mounting hole 11 penetrates through the bracket body 10 in the up-and-down direction. When the pole column 200 is fitted with the busbar bracket assembly 100, the pole column 200 is arranged in the mounting hole 11, and the end of the pole column 200 leaks out from the mounting hole 11. Preferably, the bracket body 10 is a suction molded part, which can reduce the weight of the bracket body 10 and also reduce the production cost of the bracket body 10.

[0036] In the busbar bracket assembly 100 of the present utility model, by providing the convex edge 112 in the mounting hole 11, the mounting hole 11 can be adapted to various types of pole columns 200, such as circular pole columns 200 and square pole columns 200, thereby improving the versatility of the busbar bracket assembly 100. At the same time, there is no need to re-open the mold design for a certain type of pole column 200, so the cost of repeated mold opening can be saved, and thus the production cost can be effectively reduced.

[0037] In the busbar bracket assembly 100 according to the embodiment of the present utility model, by providing the convex edge 112 in the mounting hole 11, the mounting hole 11 can be adapted to various types of pole columns 200, thereby improving the versatility of the busbar bracket assembly 100. At the same time, the production cost can also be effectively reduced.

[0038] According to some embodiments of the present utility model, referring to Figure 4 and Figure 5 , the hole edge of the mounting hole 11 includes at least four edges 111. That is to say, the hole edge of the mounting hole 11 can include four, five or six or more edges 111. The edges 111 are connected end to end, and a convex edge 112 is provided on each edge 111. The convex edge 112 is formed into an arc shape. Thus, the edge 111 has a simple structure, which is convenient for the processing of the mounting hole 11, thereby improving the production efficiency of the mounting hole 11. At the same time, since the convex edge 112 is an arc shape, the mounting hole 11 can be adapted to various pole columns 200, thereby ensuring the versatility of the mounting hole 11.

[0039] For example, as Figure 4 and Figure 5 shown, the mounting hole 11 includes four edges 111. The edges 111 extend in a straight line, and a convex edge 112 is formed on each edge 111. The convex edge 112 is an arc protruding in the direction radially outward of the mounting hole 11.

[0040] According to some alternative embodiments of the present utility model, referring to Figure 4 andFigure 5 The adjacent edges 111 are arranged at an included angle, and a chamfer is formed at the connection of the adjacent edges 111. Thus, the chamfer can facilitate the installation of the terminal post 200 in the mounting hole 11. At the same time, it can also prevent the edge of the mounting hole 11 from rubbing against the surface of the terminal post 200, thereby protecting the terminal post 200.

[0041] For example, as Figure 4 and Figure 5 shown, the adjacent edges 111 are arranged at a right angle, and an external chamfer is formed at the connection of the adjacent edges 111.

[0042] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 4 , a plurality of mounting holes 11 are provided on the bracket body 10. That is to say, two, three, four or more mounting holes 11 are provided on the bracket body 10. The plurality of mounting holes 11 are arranged at intervals along the length direction of the bracket body 10 (such as the left - right direction shown in Figure 3 ), and the mounting holes 11 are adapted to correspond to the number of terminal posts 200 one by one. Thus, the plurality of mounting holes 11 can ensure that a plurality of terminal posts 200 can be arranged in the mounting holes 11, thereby facilitating the connection between adjacent terminal posts 200.

[0043] For example, as Figure 3 and Figure 4 shown, the mounting holes 11 are divided into two columns in the front - rear direction, and the two columns of mounting holes 11 are arranged at intervals in the left - right direction.

[0044] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 6 , the busbar bracket assembly 100 includes: a connecting member 20. The two ends of the connecting member 20 (such as the left and right ends of the connecting member 20 shown in Figure 3 ) are respectively arranged on adjacent mounting holes 11, and the connecting member 20 is adapted to connect adjacent terminal posts 200. Thus, the connecting member 20 can electrically connect adjacent terminal posts 200, so that the terminal posts 200 of the entire battery cell can be electrically connected through the busbar bracket assembly 100, and further ensure the normal function of the battery module 1000.

[0045] For example, as Figure 3 and Figure 6 shown, the connecting member 20 extends in the left - right direction. The left and right ends of the connecting member 20 are arranged on the mounting holes 11, and the left and right ends of the connecting member 20 are respectively electrically connected to the corresponding terminal posts 200.

[0046] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 6, the connecting member 20 is provided with a positioning hole 21, and the positioning hole 21 is adapted to position the connection position with the pole 200. Thus, the positioning hole 21 can assist in the connection between the connecting member 20 and the pole 200, enabling the connecting member 20 to be connected to the pole 200 at an appropriate position, thereby saving installation time and improving installation efficiency.

[0047] For example, as Figure 3 and Figure 6 shown, a positioning hole 21 is provided on each of the left and right sides of the connecting member 20, and the positioning hole 21 penetrates the connecting member 20 in the up and down direction. Preferably, the connecting member 20 and the pole 200 are connected by welding, which can ensure the welding strength between the connecting member 20 and the pole 200.

[0048] According to some embodiments of the present invention, referring to Figure 1 , Figure 3 and Figure 6 , the connecting member 20 is provided on one side of the thickness direction of the bracket body 10 (such as the up and down direction shown in Figure 1 ), at least a part of the connecting member 20 is formed as a fixing portion 22 protruding toward the bracket body 10, and a fixing hole 221 is provided on the fixing portion 22. The connecting member 20 is fixed to the bracket body 10 through the fixing hole 221. Thus, the fixing portion 22 can strengthen the strength of the connecting member 20, thereby preventing the connecting member 20 from being damaged. At the same time, the fixing portion 22 can absorb the displacement of the pole 200 caused by the expansion of the battery cell, thereby ensuring that the pole 200 is always connected to the connecting member 20. In addition, the fixing hole 221 can facilitate the connection between the connecting member 20 and the bracket body 10, thereby improving the connection efficiency.

[0049] For example, as Figure 1 , Figure 3 and Figure 6 shown, the connecting member 20 is provided on the upper side of the bracket body 10, a fixing portion 22 protruding downward is formed at the middle position of the connecting member 20, two fixing holes 221 are provided on the fixing portion 22, the fixing holes 221 penetrate the fixing portion 22 in the up and down direction, and the two fixing holes 221 are arranged at intervals in the front and back directions. Preferably, the connecting member 20 and the bracket body 10 are connected by hot riveting, so as to ensure the connection strength between the connecting member 20 and the body bracket.

[0050] According to some embodiments of the present invention, referring to Figure 3 and Figure 6 , the connecting member 20 is provided with a notch 23, and the notch 23 is along the thickness direction of the connecting member 20 (such as Figure 6The up-and-down direction shown) penetrates through the connecting member 20. Thus, providing the notch 23 can facilitate and accurately determine whether the connecting member 20 is correctly installed, thereby ensuring the installation efficiency. At the same time, it can also prevent short circuits caused by the reverse connection between the connecting member 20 and the pole 200, thereby ensuring the safe use of the battery module 1000.

[0051] For example, as Figure 3 and Figure 6 shown, a notch 23 is provided at the connection position of the left side and the rear side of the connecting member 20. The notch 23 penetrates through the connecting member 20 in the up-and-down direction, and the edge of the connecting member 20 adjacent to the notch 23 extends obliquely in the direction from the left front to the right rear.

[0052] According to some embodiments of the present utility model, referring to Figure 2 and Figure 3 , a clamping structure 12 is provided on the bracket body 10, and the clamping structure 12 is adapted to be detachably connected to the cover body 300. Thus, the connection form between the bracket body 10 and the cover body 300 is simple, which can facilitate the connection between the bracket body 10 and the cover body 300, and further improve the connection efficiency.

[0053] For example, as Figure 2 and Figure 3 shown, the clamping structure is formed as a snap, and a snap hole 310 is provided on the cover body 300. The snap cooperates with the snap hole 310 to realize the connection between the bracket body 10 and the cover body 300.

[0055] For example, as Figure 1 , Figure 2 and Figure 3 shown, a pole 200 is provided on the upper side of the battery cell, the cover body 300 covers the upper side of the battery cell, the busbar bracket assembly 100 is located between the battery cell and the cover body 300, the busbar bracket assembly 100 is electrically connected to the pole 200, and the busbar bracket assembly 100 is connected to the cover body 300 through the clamping structure 12.

[0056] According to the battery module 1000 of the embodiment of the present utility model, by providing the busbar support assembly 100 of the above first aspect embodiment, a convex edge 112 is provided in the mounting hole 11, so that the mounting hole 11 can be adapted to various types of pole columns 200, thereby improving the versatility of the busbar support assembly 100. At the same time, the production cost can be effectively reduced.
