The mounting bracket is large in size and complex in structure, in order to enable the mounting bracket to effectively and stably fix and protect the battery box body, the mounting bracket needs to have higher structural strength, so that the structure of the mounting bracket can be utilized to effectively protect the battery box body when the battery box body is impacted and extruded outside, and the mounting bracket is complex in structure and high in cost.

2. After the installing support is designed, when all the battery boxes are stacked and fixed in the installing support, the battery boxes are required to be gradually pushed into the installing support by adopting hoisting equipment such as a crane, and then the battery boxes are fixed in the installing support by utilizing screws and the like.

Aiming at the defects existing when the battery box body is fixed by using the mounting bracket in the prior art, the inventor considers that the problems are caused by the arrangement of the mounting bracket to a great extent through optimization and improvement, so that a new way is developed, the fixing structure of the mounting bracket is canceled, and if the structure of the battery box body is used as the bracket, the mounting bracket can be avoided, the structure is greatly simplified, and the mounting efficiency of the battery box body is improved.

Although the mode of taking the battery box body as a bracket by canceling the mounting bracket can effectively simplify the structure and save the cost, the practical operation still has problems because: the battery box in the prior art mainly comprises a bottom plate, an upper cover and four frames connected between the bottom plate and the upper cover, wherein the four frames are low in strength, so that the battery box can not protect the battery in the battery box when the battery box is subjected to working conditions such as large vibration, mechanical impact, collision and extrusion after being stacked and connected. Therefore, the inventor considers that if the structure of the battery box body is improved, the structural strength of the battery box body is enhanced, so that the structure of the battery box body can bear larger vibration, mechanical impact, collision and extrusion to meet the use requirement, and the problems can be effectively solved.
