The bracket 4 and the transition bracket 4 are respectively connected to the supporting horizontal plate 2 and the fixed plate 3 at both ends. The transition bracket 4 is provided with several protrusions 5 on the side away from the supporting horizontal plate 2. Specifically, the transition bracket 4 plays a transition role. The battery box 1 includes a side plate 101, a bottom plate 102 and a limiting plate 103. There are two side plates 101, which are located on both sides of the bottom plate 102. The limiting plate 103 is located between the two side plates 101 and is fixedly connected to the two side plates 101 at both ends. Specifically, it can maximize the utilization of space, has low manufacturing cost and high strength.
[0018] Please see Figure 1-2 As shown, furthermore, each of the two transition brackets 4 has several threaded holes, and hexagonal flange bolts 6 are installed on the threaded holes.
[0019] In this embodiment, the installation and disassembly of the battery box 1 are facilitated by providing threaded holes and hexagonal flange bolts 6.
[0020] Please see Figure 1-2 As shown, furthermore, the side plate 101 has several through holes 7.
[0021] In this embodiment, the through hole 7 facilitates the dissipation of battery heat.
[0022] Furthermore, the supporting horizontal plate 2 and the fixing plate 3 are integrated with the battery box 1, and the bottom plate 102 is integrated with the side plate 101 and the limiting plate 103.
[0023] In this embodiment, the strength of the battery housing 1 is enhanced so that it can withstand external pressure and impact, protect the battery from damage, provide sufficient mechanical support, increase the battery's durability, and maintain a good working condition even in environments with high vibration (such as electric vehicles).
