[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] A copper bar bracket 1, such as Figures 1 to 8 As shown, including,

[0036] A support 11 for connecting the box body;

[0037] A first mounting plate 12 connected to the support 11;

[0038] The second mounting plate 13 is connected to the first mounting plate 12 . The first mounting plate 12 and the second mounting plate 13 are arranged in parallel. Both the first mounting plate 12 and the second mounting plate 13 are provided with through holes 14 for connecting the copper busbar mounting member 2 .

[0039] Specifically, the utility model proposes a new type of copper busbar bracket 1, which has a simple and reliable structure, is easy to manufacture, and also reduces the cost to a certain extent; when using the copper busbar bracket 1, it can realize flexible changes in the fixation of the copper busbar 4, and can have a variety of different fixing layout methods, with high compatibility.

[0040] In a preferred embodiment, a connecting portion 15 is provided on the first mounting plate 12 , and is connected to the second mounting plate 13 via the connecting portion 15 . The distance between the first mounting plate 12 and the second mounting plate 13 is equal to the width of the connecting portion 15 .

[0041] In a preferred embodiment, it includes a plurality of groups of through holes 14 , each group of through holes 14 is distributed on the first mounting plate 12 and the second mounting plate 13 along a first direction; the distribution position of each group of through holes 14 corresponds to the buckle 21 on the copper busbar mounting piece 2 .

[0042] Specifically, the utility model provides multiple groups of through holes 14 to meet the vertical arrangement of various copper bars 4, and has good practicality. Taking four groups of through holes 14 as an example, the four groups of through holes 14 include a first group of through holes 14 located on the upper part of the first mounting plate 12, a second group of through holes 14 located below the first group of through holes 14, a third group of through holes 14 located on the upper part of the second mounting plate 13, and a fourth group of through holes 14 located below the third group of through holes 14; each group of through holes 14 has two holes, corresponding to the two buckles 21 provided on the copper bar mounting member 2;

[0043] like Figures 3 to 8 As shown, the connection modes of the copper bar bracket 1 and the copper bar mounting member 2 of the utility model include single-row type and double-row type;

[0044] The single-row type is that the copper bar mounting member 2 is connected to the side of the first mounting plate 12 facing away from the second mounting plate 13 or to the side of the second mounting plate 13 facing away from the first mounting plate 12. The utility model includes four single-row connection methods in which the buckles 21 are buckled into each group of through holes 14 respectively.

[0046] The double-row type is that a copper bar mounting part 2 is provided on the side of the first mounting plate 12 facing away from the second mounting plate 13 and on the side of the second mounting plate 13 facing away from the first mounting plate 12. Based on the setting height of the buckle 21 on the copper bar mounting part 2 and the height of the through hole 14 into which the buckle 21 is buckled, the first copper bar mounting part 22 arranged on the first mounting plate 12 and the second copper bar mounting part 23 arranged on the second mounting plate 13 can have the same horizontal height. This connection method is a flush double-row type. Of course, according to actual use needs, the first copper bar mounting part 22 and the second copper bar mounting part 23 can also have different horizontal heights. This connection method is an oblique offset double-row type.

[0047] The utility model realizes structural compatibility by setting a reasonable hole array and a double-layer mounting surface formed by the first mounting plate 12 and the second mounting plate 13, and can be compatible with various ways of arranging and fixing the copper bar 4, including single copper bar 4 with multiple positions and double copper bar 4 with multiple positions, so as to realize the layout and fixing of the copper bar 4 in various environments under various battery pack spaces, thereby facilitating the design of highly integrated battery packs.

[0050] Specifically, the copper busbar bracket 1 in the present invention adopts a sheet metal structure and is manufactured by integrated stamping and forming. The sheet metal used to prepare the copper busbar bracket 1 is first prepared with a through hole 14, and then the areas with the through hole 14 are respectively stamped to form a first mounting plate 12 and a second mounting plate 13. This method is simple to prepare, does not require an additional welding process, and has lower costs. Therefore, the present invention has the effects of simple structure, high cost performance, and good manufacturing feasibility.

[0053] The copper busbar mounting member 2 is disposed on the first mounting plate 12 and / or the second mounting plate 13 and is connected to the copper busbar 4 .

[0054] Specifically, the assembly process is as follows:

[0055] Step 1, connecting the copper bar bracket 1 to the battery box 3 by welding;

[0056] Step 2, fix the buckle 21 of the copper bar mounting piece 2 in the through hole 14 by pressing, so as to realize the connection between the copper bar 4 fixing piece and the copper bar bracket 1;

[0057] Step 3, placing the copper busbar 4 in the mounting groove of the copper busbar mounting member 2, and fixing the copper busbar 4 through the copper busbar mounting member 2, thereby completing the overall assembly.
