Problems solved by technology
In order to ensure sufficient battery life, a larger battery needs to be placed on the layout of the whole machine. Currently, the battery packs used for excavators on the market are generally large in size and heavy in weight.
In addition, due to the high storage conditions of the battery, if the battery is inconvenient to assemble or fails later, it will seriously affect the service life of the battery and cause unnecessary waste of manpower and material resources.

The invention relates to a battery box, and concretely relates to a battery mounting box. The battery mounting box comprises a lower-layer box body structure, at least one middle-layer box body structure and an upper-layer box body structure, the lower-layer box body structure, the middle-layer box body structures and the upper-layer box body structure are each internally provided with a cavity used for installing a battery pack, the lower-layer box body structure and the middle-layer box body structures, the adjacent middle-layer box body structures and the middle-layer box body structures and the upper-layer box body structure are detachably connected through connecting assemblies respectively, and a mounting plate is mounted on the side surface of a mounting box structure formed by superposing the lower-layer box body structure, the middle-layer box body structure and the upper-layer box body structure, so that a closed structure can be formed. The battery mounting box has the advantages of being simple in structure and convenient to disassemble and assemble, meanwhile, the battery mounting box has good heat preservation and heat insulation functions, and the service life of a battery pack can be prolonged. In addition, the invention also relates to a battery box comprising the battery mounting box, and an electric excavator.
Description
technical field [0001] The present invention relates to a battery box, in particular to a battery installation box. In addition, the present invention also relates to a battery box and an electric excavator including the battery installation box. Background technique [0002] In recent years, oil resources have become increasingly tense, and environmental problems have continued to deepen. my country has paid more and more attention to energy conservation and emission reduction. Electric excavators with zero emissions and low noise have become new market competition points. The electric excavator uses a combination of motor and battery to replace the traditional fuel engine. The kinetic energy is provided by the battery and the drive motor. Compared with the traditional fuel excavator, it is more energy-efficient and achieves low noise and zero emissions. Especially used in urban areas, tunnels, plateaus and other working conditions. In order to ensure sufficient battery ...
