Technical Field

[0001] The utility model relates to a battery box structure and belongs to the field of engineering machinery. Background Art

[0002] At present, the field of construction machinery is developing towards electrification. Construction machinery is different from road machinery such as passenger cars and commercial vehicles. The application scenarios of construction machinery are more diversified. Common working conditions include rock, mine, earthwork, etc. These environments are relatively harsh, so construction machinery has higher requirements for structural strength, and it must also be easy to repair and maintain.

[0003] The existing technology is a welded frame, in which four groups of L-shaped columns, a bottom plate and a crossbeam form the main frame, and the batteries and mounting plates are arranged in sequence from bottom to top, and are assembled in sequence starting from the bottom layer.

[0004] Since the main body of the frame is a welded structure, it needs to be installed from the bottom upwards. Similarly, when the bottom battery needs to be removed, all batteries and structural parts on the upper layer of the bottom battery need to be removed. Once the bottom battery needs to be repaired or replaced, the entire battery frame needs to be disassembled, which seriously increases the workload of after-sales service personnel. Summary of the invention

[0013] In some embodiments, the enclosure of the frame is provided with a limiting hole at a position where it contacts the mounting plate, and the protruding portion of the end of the mounting plate can be inserted into the limiting hole to prevent the limiting plate from shaking up and down.

[0014] In some embodiments, the mounting plate is provided with a threaded hole at the position where it contacts the limiting plate, and the protruding portion of the limiting plate is provided with a through hole coaxially arranged with the threaded hole. The limiting plate and the mounting plate are fixed together by bolts to prevent the limiting plate from shaking up and down.

[0015] In some embodiments, a through hole for heat dissipation and weight reduction is provided in the middle of the mounting plate.

[0016] In some embodiments, through holes are provided at both ends of the limit plate at the positions in contact with the left vertical plate and the right vertical plate of the frame, and threaded holes coaxially arranged with the through holes are provided on the left vertical plate and the right vertical plate of the frame, and the limit plate is fixed to the frame by bolts.
