[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The lightweight battery box keel structure and the battery box are provided with a locking mechanism. The guiding plate and the pressing plate are locked through the locking mechanism, so that the pressing and fixing of the pressing plate are more stable and firm. At the same time, the upward movement of the pressing plate due to vibration is prevented by locking the pressing plate, and the pressing plate can be quickly disassembled, so that the lightweight battery box keel structure and the battery box can be used normally.

[0018] 2. The lightweight battery box keel structure and the battery box are provided with a clamping mechanism. Through the clamping mechanism, the support plate can be quickly installed in a clamping manner, and at the same time, it can prevent the support plate from shifting or deviating, which may cause accidents such as squeezing the battery when being impacted. During maintenance, it can be quickly disassembled, enabling the lightweight battery box keel structure and the battery box to be used normally.

[0019] 3. The lightweight battery box keel structure and the battery box are provided with a receiving mechanism. Through the receiving mechanism, the isolation plate is supported to divide the battery box into upper and lower parts, which facilitates the rapid positioning and firm support of the isolation plate, prevents the isolation plate from shifting when the battery box is impacted, resulting in the failure of battery protection, and at the same time, it is convenient for disassembly during maintenance, enabling the lightweight battery box keel structure and the battery box to be used normally.

[0020] 4. The lightweight battery box keel structure and the battery box are provided with rollers and a clamping plate. Through the guidance of the rollers, the clamping plate is bent, preventing the clamping plate from being unable to be clamped with the first clamping block, and at the same time, preventing the clamping block from being worn and damaged, resulting in the failure of clamping fixation.
