Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a battery box which is convenient for installing a battery pack. Background Art

[0002] The main functions of the battery box include battery insulation, waterproofing, and protecting the battery from collision. In addition, the battery box is generally sealed to prevent the leakage of gas and liquid inside the battery, thereby reducing the risk of battery spontaneous combustion. In order to ensure the safety and life of the battery box, a series of protection measures need to be taken, such as overcharge protection, over-discharge protection, over-temperature protection, and short-circuit protection. When installing the battery box, some precautions need to be followed, such as the battery should be placed upright and not inverted, and it should be pressure-proof, waterproof, and firmly installed.

[0003] With respect to the above-mentioned related technologies, the inventors found that when connecting a battery to a battery box, a plurality of bolts are usually used to fix the bottom of the battery to the bottom of the battery box. When the battery is subsequently maintained and replaced, workers are required to reach into the bottom of the inner cavity of the battery box to operate, which reduces the convenience of operation.

[0013] By adopting the above technical solution, the slot on the limit plate is clamped on the corresponding C-shaped steel, the limit plate is located at the end of the battery pack, and the bolt is rotated to make its end contact with the inner wall of the battery box body, thereby driving the limit plate to closely contact with the end of the battery pack, so that the battery pack is limited in the horizontal direction, thereby achieving the purpose of fixation.

[0014] In a preferred example, the present invention can be further configured as follows: the upper planes of the U-shaped plates are respectively connected with arc-shaped hooks.

[0015] By adopting the above technical solution and using the arc-shaped hook, it is convenient for operators to use lifting tools to lift the battery pack into or out of the inner cavity of the battery box body, thereby improving the convenience of operation.

[0016] In a preferred example, the utility model can be further configured as follows: the U-shaped frame also includes two V-shaped positioning grooves arranged at intervals, the inner cavity of the V-shaped positioning groove is provided with the strip pad, and the V-shaped positioning groove is connected to the bottom of the battery box body.

[0017] By adopting the above technical solution and setting the V-shaped positioning groove, the bottom of the vertical limit frame assembly falls into the inner cavity of the V-shaped positioning groove, which facilitates the C-shaped steel passing through the side wall of the battery box body to smoothly enter the inner cavity of the C-shaped groove body, thereby improving the convenience of operation.
