Abstract

The invention discloses an all-aluminum frame battery pack box body with multi-point penetration constraint. A battery module is placed in a battery pack box body, and the weight of the battery moduleis mainly withstood by longitudinal beams and a module mounting longitudinal beam. More than three supporting connecting blocks are arranged on the upper side surface of each longitudinal beam in thelength direction of the longitudinal beams. A damping sponge cushion is arranged between the upper end face of each supporting connecting block and an upper cover. The longitudinal beams, the supporting connecting blocks, the damping sponge cushion and the upper cover are connected through bolts and nuts in a fastened manner to form a body. Therefore, the gravity, acting on the longitudinal beamsand the module mounting longitudinal beams, of the battery module can be dispersed to the upper cover, the gravity of the battery module is prevented from completely acting on the bottom plate of thelower box body, the displacement deformation of the middle area of the bottom plate of the lower box body can be effectively prevented, and the bearing capacity of the battery pack box body on the battery module is improved.

Description

technical field [0001] The invention belongs to the technical field of battery boxes for electric vehicles, and in particular relates to an all-aluminum frame battery pack box with multi-point penetration constraints. Background technique [0002] The battery pack box is an important part of the new energy electric vehicle. It is usually installed at the lower part of the car body. The carrier of the battery pack plays a key role in the safe operation and protection of the battery pack. In order to save energy, protect the environment and reduce weight, the battery pack box is made of lightweight materials such as aluminum alloy. [0003] Through long-term research and test and use practice, it is found that the existing battery pack box has a poor load-bearing capacity for the battery module, and the middle area of ​​the bottom plate of the lower box is prone to large displacement and deformation, which cannot meet the needs of the internal batteries. Mod protection requi...
