Description

Technical Field

[0001] This utility model belongs to the field of battery casings, and in particular relates to an electrical mounting plate and a battery box. Background Technology

[0002] The battery box is equipped with an electrical mounting plate. Those skilled in the art can install electrical structures such as PDU (Power Distribution Unit), BMS (Battery Management System), contactors, and fuses on the electrical mounting plate according to actual needs.

[0003] For example, such as Figure 1 As shown, the electrical assembly includes an electrical mounting plate 1, on which a contactor 2 and a fuse 3 are mounted. The fuse 3 is mounted on the electrical mounting plate via a fuse holder 6. The fuse 3 and the contactor 2 are electrically connected via a first copper busbar 4 and a second copper busbar 5. One end of the first copper busbar 4, one end of the second copper busbar 5, and one connection terminal of the fuse 3 are electrically connected to form a first connection point; the other end of the first copper busbar 4 is electrically connected to one connection terminal of the contactor 2, forming a second connection point; and the other end of the second copper busbar 5 is electrically connected to another connection terminal of the contactor 2, forming a third connection point.

[0004] like Figure 1 As shown, the first connection point, the second connection point, and the third connection point are all located at different heights. Therefore, both the first copper busbar 4 and the second copper busbar 5 have upward bending parts, resulting in a complex structure. Processes such as dip coating, extrusion, or electroplating must be used to protect the copper busbars, which leads to higher costs.

[0005] For example, in the patent documents with authorization announcement number CN218783353U and application publication number CN116916574A, various electrical structures are installed on the mounting plane of the electrical mounting plate, and the connection terminals of the two electrical structures connected by copper busbars are located at different heights, which means that the copper busbars must have an upward bending part. The copper busbars must be protected by processes such as dip coating, extrusion or electroplating, which is costly. Utility Model Content

[0040] Method 1: Raise the height of one of the electrical components individually;

[0041] Method 2: Reduce the height of one or all of the electrical components individually;

[0042] Method 3: While raising one electrical structure, lower part or all of the height of the other electrical structure.

At this time, since both ends of the strip-shaped copper bar are at the same height, the strip-shaped copper bar can be protected by low-cost processes such as the heat shrink tube 11 process, which is beneficial to cost reduction.

[0064] Specific Embodiment 3 of the electrical installation board provided by the present utility model:

[0065] Refer to Figures 2-5 As shown, the main difference between this embodiment and Specific Embodiment 1 is that in Specific Embodiment 1, both the first bracket and the second bracket are provided on the board body 1, while in this embodiment, only the second bracket is provided on the board body 1.

[0066] The electrical installation board includes a board body 1. The board body 1 is provided with a first installation part for installing the first electrical structure. The board body 1 is also provided with a second bracket and an avoidance hole 101 for avoiding the second electrical structure.

The heights of the first installation part, the second installation part, and the third installation part satisfy that the first electrical structure and the second electrical structure are electrically connected by a strip-shaped copper bar with both ends at the same height.

[0076] At the same time, the contactor 2 section is moved down, and the height of the electrical mounting plate and the battery components on it is reduced, which can improve the overall space utilization and increase the energy density of the battery box.

At the bottom of the two first vertical plates located at the edge, on the side away from the other first vertical plates, there are first connecting plates for connecting to the board body. At the bottom of the two first vertical plates located in the middle, there is a second connecting plate connecting the two first vertical plates. The first mounting plate constitutes the first mounting portion.

6. An electrical mounting plate, comprising a plate body, characterized in that, The board body is provided with a first mounting portion for mounting a first electrical structure. The board body is further provided with a second bracket and an avoidance hole for avoiding a second electrical structure. The second bracket is provided with a second mounting portion located below the avoidance hole. The second mounting portion is used for mounting at least a part of the second electrical structure. When the second mounting portion is used for mounting all of the second electrical structure, the heights of the first mounting portion and the second mounting portion satisfy that: the first electrical structure and the second electrical structure are electrically connected by a strip-shaped copper row with both ends at the same height. When the second mounting portion is used for mounting a part of the second electrical structure, the board body is further provided with a third mounting portion for mounting another part of the second electrical structure. The heights of the first mounting portion, the second mounting portion and the third mounting portion satisfy that: the first electrical structure and the second electrical structure are electrically connected by a strip-shaped copper row with both ends at the same height.

7. The electrical mounting plate as described in claim 6, characterized in that, The second bracket is a "C"-shaped bracket. The second bracket includes two second vertical plates. At the top of each second vertical plate on the side away from the other second vertical plate, there is a third connecting plate for connecting with the board body. At the bottom of the two second vertical plates, there is a second mounting plate connecting the two second vertical plates. The second mounting plate constitutes the second mounting portion.

8. A battery box, comprising an electrical mounting plate and an electrical structure mounted on the electrical mounting plate, characterized in that, The electrical mounting board is the electrical mounting board according to any one of claims 1 to 3.

9. The battery box as described in claim 8, characterized in that, The first electrical structure includes a fuse and a fuse holder. The fuse holder is mounted on the first bracket. The second electrical structure includes a contactor. The contactor and the fuse are electrically connected by two strip-shaped copper rows with both ends at the same height. A "Z"-shaped copper row is also electrically connected to the connection terminal on the side of the fuse away from the strip-shaped copper row. The "Z"-shaped copper row includes two horizontally arranged horizontal connection terminals and a vertical portion connecting the two horizontal connection terminals.

10. A battery box, comprising an electrical mounting plate and an electrical structure mounted on the electrical mounting plate, characterized in that, The electrical mounting board is the electrical mounting board according to any one of claims 4 to 7.
