[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram showing the interaction between the battery housing and an embodiment of this utility model. Figures 1 to 2 The space-saving BDU fixing bracket shown is characterized by comprising: a first bracket plate 1 and a second bracket plate 2, both of which are square structures. The first bracket plate 1 is arranged horizontally and has a mounting hole 11 along the vertical direction. The second bracket plate 2 is arranged vertically on the first bracket plate 1 and has a first mounting protrusion 31, which is perpendicular to the second bracket plate 2.

[0023] For example, in this embodiment of the present invention, both the first support plate 1 and the second support plate 2 are made of 1.0mm thick steel, effectively reducing weight and achieving the goal of lightweighting. The overall solution adopts sheet metal bending, sheet metal stamping and riveting processes, eliminating the need for welding. It can be stamped with an integrated mold, effectively reducing weight and achieving the goal of lightweighting with high precision and fewer steps. This solution adopts the form of discrete BDU components, which can be freely arranged on the first mounting protrusion 31. First, the various BDU parts are mounted on the second support plate 2 through the first mounting protrusion 31 and the wiring is connected. Then, the fixed bracket and BDU parts are set as a whole on the battery pack housing. The fixed bracket is fixed to the battery pack housing by using screws and other fasteners through the mounting holes 11 and the assembly holes on the housing. Since the BDU components are vertically arranged and mounted on the second bracket plate 2, the overall structure occupies more vertical space and less horizontal space. In a battery pack, sufficient horizontal space is usually required for the cells to be stacked in order to maximize their capacity. However, there is usually a narrow vertical space between the cells and the casing. By setting this fixing bracket in this form, the BDU assembly can be installed in the vertical space between the cells and the casing, thus leaving more assembly space for the cells and improving the overall energy density of the battery pack.
