[0037] When using the battery pack for the electric stacker, the battery body 4 adopts the same type as the 18650 lithium battery. The battery body 4 transmits power to the inside of the cable tray 32 through the conductive post 31. The cable tray 32 is electrically connected to the outside through the flexible wire 33 and the terminal 5. When the servo motor 10 is turned on, under the support of the support frame 6, the servo motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the rotating disk 12 and the first shaft 13 to rotate. Under the sliding connection of the first shaft 13 and the sector gear 14, and under the sliding of the sliding groove inside the first shaft 13 and the sector gear 14, and under the limiting support of the second shaft 15, the first shaft 13 drives the sector gear 14 to reciprocate around the second shaft 15 as the axis. Under the meshing of 17, the sector gear 14 drives the support column 16, rack 17, support plate 18, and fan 19 to reciprocate. The support frame 6 provides sliding support to the support column 16. Multiple sets of fans 19 are turned on, allowing the fans 19 to reciprocate and blow air to cool the battery pack body 3 and battery body 4. When it is time to replace the battery pack body 3, two sets of electric push rods 7 are turned on. With the support of the housing 1, the electric push rods 7 drive the rotating shaft 8 to move. With the limit support of the support shaft 9, the rotating shaft 8 drives the cover plate 2 to rotate around the support shaft 9, so that the cover plate 2 and the housing 1 rotate at a certain angle, exposing the battery pack body 3 for replacement. This realizes the reciprocating movement of the battery pack for heat dissipation and facilitates opening the cover to take out and put in the battery pack.

[0038] The housing 1 has a base plate 20 installed inside, a lifting plate 21 is provided on the outside of the base plate 20, a stepper motor 22 is installed on the inner wall of the base plate 20, and a threaded rod 23 is installed at the output end of the stepper motor 22.

The first support arm 25 is movably installed on both sides of the threaded block 24, and two sets of second support arms 26 are movably installed inside the base plate 20.

[0040] A movable shaft 27 is movably installed at the intersection of the first support arm 25 and the second support arm 26. The movable shaft 27 passes through the first support arm 25 and the second support arm 26 and extends to their outside. First rollers 28 are movably installed on the outer wall of the first support arm 25. The first rollers 28 are slidably connected to the base plate 20.

[0041] The side of the first support arm 25 away from the base plate 20 is movably connected to the lifting plate 21. A third shaft 29 is provided on the outside of the lifting plate 21. The second support arms 26 are all connected to the third shaft 29. Second rollers 30 are movably installed at both ends of the third shaft 29. The second rollers 30 are slidably connected to the lifting plate 21.

[0042] Conductive posts 31 are installed at the bottom of the battery body 4, and wire bars 32 are symmetrically installed inside the battery pack body 3. The conductive posts 31 are all electrically connected to the wire bars 32.

[0043] Three sets of flexible wires 33 with equal spacing are installed on the side wall of the battery pack body 3. One end of each flexible wire 33 is connected to the wire bar 32 through the battery pack body 3, and the other end of each flexible wire 33 is electrically connected to the terminal block 5.

[0044] When replacing the battery pack body 3, the stepper motor 22 is turned on. Supported by the base plate 20, the stepper motor 22 drives the threaded rod 23 to rotate. With the threaded connection between the threaded rod 23 and the threaded block 24, the threaded rod 23 moves the threaded block 24. With the sliding connection between the first roller 28 and the base plate 20, the threaded block 24 moves the first support arm 25 and the first roller 28. With the movable connection between the base plate 20 and the second support arm 26, and the movable support of the movable shaft 27, the first support arm 25 drives the movable shaft 27 and the second support arm 26 to rotate. With the wheel 30 slidingly connected to the lifting plate 21, the second support arm 26 drives the third shaft 29 and the second roller 30 to slide inside the lifting plate 21, causing the lifting plate 21 to rise and fall to a specified height. This moves the battery pack body 3 and battery body 4 to the outside of the housing 1, removes multiple sets of flexible wires 33, and takes out the battery pack body 3 and battery body 4 for replacement. After replacement, the stepper motor 22 is turned on in reverse to facilitate lowering to the bottom for protection. This achieves convenient lifting and lowering control adjustment of the battery pack, facilitates lowering to the bottom for safety protection, and improves the convenience of battery pack replacement.

[0045] Work steps

[0046] Servo motor 10 drives rotating shaft 11 to rotate, which in turn drives rotating disk 12 and first shaft 13 to rotate. Under the sliding connection of first shaft 13 and sector gear 14, and the limiting support of second shaft 15, first shaft 13 drives sector gear 14 to reciprocate around second shaft 15. Sector gear 14 drives support column 16, rack 17, support plate 18, and fan 19 to reciprocate, turning on multiple sets of fans 19 to reciprocate and blow air to cool battery pack body 3 and battery body 4. When it is time to replace battery pack body 3, electric push rod 7 drives rotating shaft 8 to move. Under the limiting support of support shaft 9, rotating shaft 8 drives cover plate 2 to rotate around support shaft 9, causing cover plate 2 to rotate at a certain angle relative to housing 1. The battery pack body 3 is exposed in preparation for replacement. When replacing the battery pack body 3, the stepper motor 22 drives the threaded rod 23 to rotate. The threaded rod 23 drives the threaded block 24 to move. The threaded block 24 drives the first support arm 25 and the first roller 28 to move. Under the support of the movable shaft 27, the first support arm 25 drives the movable shaft 27 and the second support arm 26 to rotate. The second support arm 26 drives the third shaft 29 and the second roller 30 to slide inside the lifting plate 21, so that the lifting plate 21 is raised and lowered to the specified height. The battery pack body 3 and the battery body 4 are moved to the outside of the box 1. The multiple sets of flexible wires 33 are removed, and the battery pack body 3 and the battery body 4 are taken out for replacement, thus completing the use of the battery pack for easy replacement.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
