[0035] Furthermore, the side walls of the first placement hole 22 and the second placement hole 32 are provided with a first clamping block 23 and a second clamping block 33 extending inwardly. There are multiple first clamping blocks 23 and second clamping blocks 33, which can axially limit the battery 5 installed in the first placement hole 22 and the second placement hole 32 to prevent the battery 5 from falling out of the first placement hole 22.

The contact portion 41 is laid on the positive and negative electrodes of the battery 5, and the connecting portion 42 connects adjacent contact portions 41 in a straight line, thereby connecting the positive and negative electrodes of adjacent batteries 5. The lead-out terminal 43 is bent and welded to the BMS board 1. In this utility model, wiring space is ensured without reducing battery capacity. The positive and negative electrodes of each battery 5 are connected through the metal connecting piece 4, ensuring an aesthetically pleasing appearance.

[0037] During assembly, several batteries 5 are first fixed in the first placement holes 22 and the second placement holes 32 of the first bracket 2 and the second bracket 3. Then, the BMS board 1 is attached to the first bracket 2 and the second bracket 3.

The utility model has a simple structure, is easy to assemble, and has better safety, greatly improving production efficiency and reducing production costs.

[0038] Example 1:

[0039] In the first embodiment, the BMS board 1 is provided with several BMS board mounting holes 11, and the several BMS board mounting holes 11 are distributed on the edge of the BMS board 1. The first bracket 2 is provided with a first mounting hole 21 at the bottom, and the second bracket 3 is provided with a second mounting hole 31 at the bottom. The several BMS board mounting holes 11 are respectively aligned with the first mounting hole 21 and the second mounting hole 31 and are connected by fasteners, so that the BMS board 1 is fixed to the first bracket 2 and the second bracket 3.

[0040] Example 2:

[0041] This second embodiment differs from the first embodiment in that the first and second brackets 2 and 3 are made of plastic, which exhibits a certain degree of elasticity. Several first extension plates 24 are provided at the bottom of the first bracket 2, and several second extension plates 34 are provided at the bottom of the second bracket 3. The extension length of these first and second extension plates 24 and 34 exceeds the thickness of the electronic components on the BMS board 1.

[0042] The first extension plate 24 is provided with a first bump 25, which is located at the center of a side wall of the first extension plate 24 and faces the installation direction of the BMS board 1. The second extension plate 34 is provided with a second bump 35, which is located at the center of a side wall of the second extension plate 34 and faces the installation direction of the BMS board 1.

[0043] In the second embodiment, the first protrusions 25 and the second protrusions 35 can be semicircular, triangular, rectangular, etc.

[0044] In addition to using nuts to secure the BMS board 1 to the first bracket 2 and the second bracket 3, in this second embodiment, a plurality of first extension plates 24 and second extension plates 34 are used to clamp the BMS board 1, partially applying force to the BMS board to prevent damage to components. The BMS board 1 is placed on the first and second bumps 25 and 35, and supported by the first and second bumps 25 and 35, thereby securing the BMS board 1 to the first and second brackets 2 and 3.

[0045] like Figure 12 As shown, in the prior art, a fixing groove 27 is generally provided on the bracket to insert the BMS board 1 sideways and fix it. Since the metal connecting piece 4 is connected to the BMS board 1 by welding, a welding spot 12 will be left on the BMS board 1 at the welding point. When the welding spot 12 is higher than the fixing groove 27, it will affect the side sliding removal of the BMS board 1 from the fixing groove 27.

[0046] like Figure 13 As shown, in the present invention, since the first bracket 2 and the second bracket 3 are made of plastic material and have a certain elasticity, when the first extension plate 24 and the second extension plate 34 clamp the BMS board 1 under force, it is only necessary to slightly apply force to the first extension plate 24 and the second extension plate 34 outward to release the restriction of the first protrusion 25 and the second protrusion 35 on the BMS board 1. The BMS board 1 will pop out from the inside of the protrusion, and there is no need to slide the BMS board 1 sideways to remove it, which greatly facilitates subsequent maintenance and replacement.

[0047] Embodiment three:

[0048] The third embodiment differs from the second embodiment in that first side shift positions 26 are respectively provided at two side corners of the bottom of the first bracket 2 , and second side shift positions 36 are respectively provided at two side corners of the bottom of the second bracket 3 .

[0049] In this third embodiment, when the BMS board 1 is installed at the bottom of the first bracket 2 and the second bracket 3, the first side gear 26 and the second side gear 36 enclose a mounting frame, and the mounting frame, the first extension plate 24 and the second extension plate 34 cooperate with each other to clamp and fix the BMS board 1, so that the BMS board 1 is placed and fixed on the first bracket 2 and the second bracket 3.

[0050] The utility model relates to an integrated bracket. In the utility model, the BMS board 1 is fixed to the bottom of the first bracket 2 and the second bracket 3. The lead-out end 43 of the metal connecting piece 4 can be directly electrically connected to the BMS board 1, reducing the wiring harness between the metal connecting piece 4 and the BMS board 1. Without the need for a complex wiring structure, the utilization rate of space can be improved and the production cost can be reduced.

[0051] In the present invention, the extension lengths of the first extension plate 24 and the second extension plate 34 exceed the thickness of the electronic components on the BMS board 1. The first extension plate 24 and the second extension plate 34 contact the outer insulating packaging layer or outer box of the battery 5, so that the electronic components on the BMS board 1 do not contact the outer insulating packaging layer or outer box of the battery 5, thereby protecting the electronic components on the BMS board 1, improving the service life of the product, and preventing defects caused by friction between the electronic components on the BMS board 1 and the outer insulating packaging layer / outer box of the battery due to external vibration.

[0052] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
