[0007] Further, the bottom of the quick loading and unloading box is slidably connected to the inner wall of the quick loading and unloading groove. A sliding column is fixedly connected to the bottom of the quick loading and unloading box. The number of the sliding columns is two. The two sliding columns are symmetrically arranged with the center of the quick loading and unloading box. Both bottoms of the two sliding columns are slidably connected to a sliding groove. A first locking hole is opened on the bottom wall of the quick loading and unloading groove. A locking housing is fixedly connected to the inner wall of the first locking hole. A limiting plate is fixedly connected to the inner side of the locking housing. A limiting block is clamped at the bottom of the limiting plate.

A second spring is fixedly connected to the bottom wall of the locking housing. One end of the second spring away from the bottom wall of the locking housing is in contact with the bottom of the limiting block. The second spring is sleeved on the outer wall of the locking column. Support feet are fixedly connected to the bottom of the battery pack housing. Second ventilation openings are opened on two sides of the battery pack housing away from each other.

[0008] Further, the number of the quick loading and unloading grooves is three. The three quick loading and unloading grooves are symmetrically arranged with the center of the battery pack housing.

[0009] Further, the main body mechanism includes a partition board, the bottom of the partition board is fixedly connected to the bottom wall of the quick loading and unloading box, and a lithium battery is fixedly connected to the bottom wall of the quick loading and unloading box.

[0010] Further, shock-absorbing and protective pads are fixedly connected to both the left and right sides of the lithium battery. A first ventilation opening is provided on the left side of the quick loading and unloading box, and a second tightening hole is provided at the bottom of the quick loading and unloading box.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting up the quick loading and unloading mechanism in the utility model, when the battery pack needs to be taken out, rotate the locking column. After the limiting plate is engaged with the inner wall of the limiting block, the second spring is compressed at this time, and the outer wall of the locking column will disengage from the second locking hole. When the second locking hole disengages, the first spring has no extrusion force, and the first spring restores. The quick loading and unloading box will be ejected from the inner wall of the quick loading and unloading groove under the influence of the first spring, so that the lithium battery can be loaded and unloaded. After the loading and unloading is completed, push the quick loading and unloading box into the inner wall of the quick loading and unloading groove, the first spring is compressed, align the second locking hole with the rotating locking column, and then rotate the locking column at this time to disengage the limiting plate from the limiting block.

[0015] 2. By setting up the heat dissipation mechanism in the utility model, during the working process of the battery pack, the coolant in the liquid cooling pipe circulates continuously, absorbing the heat generated by the battery pack. At the same time, the fan rotates, and the hot air near the battery pack is discharged through the ventilation area. The external cold air enters from the first ventilation opening, forming air convection, further enhancing the heat dissipation effect. The heat dissipation effect of the liquid cooling pipe and the air flow driven by the fan cooperate with each other, achieving the effect of effectively reducing the working temperature of the battery pack and ensuring its stable operation.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

During the operation of the battery pack, the coolant in the liquid cooling pipe 301 circulates continuously to absorb the heat generated by the battery pack. At the same time, the fan 303 rotates, and the hot air near the battery pack is discharged through the ventilation part 302. The external cold air enters from the first ventilation port 204, forming air convection and further enhancing the heat dissipation effect. The heat dissipation effect of the liquid cooling pipe 301 and the air flow driven by the fan 303 cooperate with each other to effectively reduce the working temperature of the battery pack and ensure its stable operation.
