However, most existing boxes directly place soft-pack lithium-ion batteries therein. Therefore, during transportation, when bumps occur, the soft-pack lithium-ion batteries are easily damaged by impact.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0008] Each of the placement chambers is also provided with a sliding mechanism and a locking mechanism. The sliding mechanism is used to ensure that the placement plate can be moved, and the locking mechanism is used to ensure that the lithium battery soft pack base is unlocked. The electric push rod is started to drive the placement plate to move down a little, so that the first magnet and the second magnet are separated, and then the lithium battery soft pack is placed in the placement chamber set in the placement box, and the lithium battery soft pack is pressed down to allow the lithium battery soft pack base to squeeze the plug rod to move to one side of the sliding mechanism until the plug rod can be plugged into the circular groove, so that the lithium battery soft pack base can be clamped, which to a certain extent avoids the situation in which the lithium battery in the lithium battery soft pack is damaged by bumps during transportation.

[0009] As a preferred embodiment of the utility model, the sliding mechanism includes two slide grooves, which are respectively opened on the inner wall of the placement box and the two opposite side walls of the cross plate, the two slide grooves are symmetrical to each other, and sliders are slidably installed in the inner cavities of the two slide grooves, the two sliders are symmetrical to each other, and the two sliders are fixedly connected to the placement plate at one end away from the slide groove. The installation position of the sliding mechanism is determined to ensure that the placement plate can move.

[0010] As a preferred embodiment of the present invention, a rectangular groove is opened above the inner cavity of the two slide grooves, the two rectangular grooves are symmetrical to each other, and the inner cavity of the two rectangular grooves is provided with a first magnet.

Because a first return spring is arranged between the slider cavity and the placement plate, when the plug rod moves toward the sliding mechanism, it will pull the first return spring to open, and when the plug rod contacts the circular groove, the first return spring contracts, so that the lithium battery soft pack base can be clamped, which to a certain extent avoids the situation in which the lithium battery in the lithium battery soft pack is damaged by bumps during transportation.

[0012] As a preferred embodiment of the utility model, the first return spring is fixedly installed at one end of the two connecting plates close to the placement plate, and the other ends of the two first return springs are fixedly connected to the outer wall of the placement plate. The installation position of the first return spring is determined.

[0013] As a preferred embodiment of the utility model, the opposite side of each first magnet and the second magnet is of opposite sex. When the lithium battery soft pack needs to be taken out, the electric push rod is started to push the placement plate to move on the sliding mechanism until the first magnet and the second magnet are attracted to each other, and the plug-in rod moves away from the circular notch, so that the lithium battery soft pack base can be ejected under the elasticity of the second return spring, thereby unlocking.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

A lithium battery soft pack 3 is placed in the inner cavity of each placement groove 7. A lithium battery soft pack base 8 is arranged at the bottom of each lithium battery soft pack 3. A circular notch 18 is arranged on the outer side wall of the lithium battery soft pack base 8. A second reset spring 19 is fixedly installed at the bottom of the inner cavity of each placement groove 7. The other end of each second reset spring 19 is movably connected to the lithium battery soft pack base 8. A sliding mechanism and a locking mechanism are also arranged in the inner cavity of each placement cavity 4. The sliding mechanism is used to ensure that the placement plate 6 can move, and the locking mechanism is used to ensure that the lithium battery soft pack base 8 is limited and unlocked. Start the electric push rod 5 to drive the placement plate 6 to move down a little, so that the first magnet 10 and the second magnet 13 are separated, and then the lithium battery soft pack 3 is placed in the placement cavity 4 set in the placement box 1, and the lithium battery soft pack 3 is pressed down to allow the lithium battery soft pack base 8 to squeeze the plug-in rod 17 to move toward the side of the sliding mechanism until the plug-in rod 17 can be plugged into the circular groove 18. Therefore, the lithium battery soft pack base 8 can be clamped, which to a certain extent avoids the situation in which the lithium battery in the lithium battery soft pack 3 is damaged by bumps and collisions during transportation.

[0024] The sliding mechanism includes two slide grooves 11, which are respectively opened on the inner wall of the placement box 1 and the two opposite side walls of the cross plate 2. The two slide grooves 11 are symmetrical to each other. Slide blocks 12 are slidably installed in the inner cavities of the two slide grooves 11. The two slide blocks 12 are symmetrical to each other. One end of the two slide blocks 12 away from the slide grooves 11 is fixedly connected to the placement plate 6. In this setting, the installation position of the sliding mechanism is determined, ensuring that the placement plate 6 can move.

[0025] Rectangular grooves 9 are respectively provided above the inner cavities of the two slide grooves 11, and the two rectangular grooves 9 are symmetrical to each other. The inner cavities of the two rectangular grooves 9 are both provided with first magnets 10. In this configuration, the installation position of the first magnet 10 is determined.

In this configuration, when the lithium battery pack 3 needs to be taken out, the electric push rod 5 is started to push the placement plate 6 to move on the sliding mechanism until the first magnet 10 and the second magnet 13 are attracted to each other. At this time, the plug-in rod 17 moves away from the circular notch 18, so that the lithium battery pack base 8 can be ejected under the elasticity of the second return spring 19, thereby unlocking.
