Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1 Combination Figure 2 As shown, the embodiment of the utility model includes:

[0017] A battery loading and unloading stacker in a container comprises a container 1 and a train track 2 inside the container, a stacker, a train roller wheel assembly 3 and a battery rack 4.

[0018] The train rail 2 is arranged in the length direction of the container 1, and the bottom of the stacker is arranged on the train rail 2 through the train roller wheel assembly 3, so that the stacker can move horizontally in the container 1 to grab the battery packs 5 at different positions.

[0019] The battery rack 4 is disposed at the back of the stacker and is used for caching and charging the battery packs 5 .

[0020] The stacker includes a base 6 , a chain lifting mechanism 7 , a lifting frame 8 , a floating platform 9 , a lateral driving mechanism, a rotating platform 10 and a bidirectional telescopic battery pack gripper 11 .

[0021] The chain lifting mechanism 7 is longitudinally fixed on both sides of the base 6 for synchronous lifting and lowering drive on both sides. A counterweight block 12 is arranged at the outer end of the chain lifting mechanism 7 for ensuring lifting balance.

[0022] The chain lifting mechanism 7 uses a dual-axis servo motor 13 in the middle to drive the synchronous rod 14 to rotate, thereby driving the driving chains 15 on both sides to move up and down synchronously, thereby realizing the lifting drive on both sides synchronously.

[0023] Two opposite sides of the chain lifting mechanism 7 are respectively provided with longitudinally distributed lifting guide rails 16 for vertical guidance of lifting.

[0024] The lifting frame 8 is horizontally distributed and its two ends are slidably arranged on the lifting guide rails 16. The tops of both sides of the lifting frame 8 are connected to the driving chain 15 of the chain lifting mechanism 7, and the driving chain 15 drives the lifting frame 8 to move longitudinally along the lifting guide rails 16.

[0025] Horizontally distributed transverse linear guide rails 17 are provided on the front and rear upper surfaces of the lifting frame 8 to provide linear movement in the direction of the transverse linear guide rails 17 .

[0026] The front and rear sides of the mounting seat of the floating platform 9 are slidably arranged on the transverse linear guide rail 17, so that the floating platform 9 can move linearly along the transverse linear guide rail 17. The floating platform 9 is used to adjust the horizontal angle to adapt to the carrying angle of the battery pack 5 of the heavy truck.

[0027] The rotating platform 10 is disposed above the floating platform 9 , and the rotating platform 10 is used to provide rotation to facilitate the grabbing and storage of the battery pack 5 of the heavy truck and the grabbing and storage of the battery pack 5 on the battery rack 4 .

[0028] The bidirectional telescopic battery pack gripper 11 is disposed on the rotating platform 10 , and the bidirectional telescopic battery pack gripper 11 is used for bidirectional telescopic grasping and placing the battery pack 5 .

[0029] The lifting frame 8 is provided with two groups of floating platforms 9 , a rotating platform 10 and a bidirectional telescopic battery pack gripper 11 for simultaneously grasping two battery packs 5 .

[0030] The transverse driving mechanism includes a driving motor 18 , a driving guide rail 19 , a driving gear 20 and a gear plate 21 .

[0032] The gear plates 21 are provided with two pieces and are respectively connected to the mounting seats of the two floating platforms 9 through the connecting plates 22. The gear surfaces of the two gear plates 21 are arranged relatively spaced apart from each other and mesh with the upper and lower sides of the driving gear 20 for transmission. When the driving motor 18 drives the driving gear 20 to rotate, the two gear plates 21 can be driven to move toward or away from each other at the same time to realize the position adjustment between the two groups of floating platforms 9.

[0033] Action flow:

[0034] The bidirectional telescopic battery pack gripper 11 equipped with the floating platform 9 and the rotating platform 10 grabs the new and old batteries and puts them into the battery rack 4;

[0035] Stack in sequence. Since the charging end of the battery pack 5 is behind the battery rack 4, a single battery rotation function is required;

[0036] The bidirectional telescopic battery pack gripper 11 grabs two empty battery packs 5 toward the heavy truck, turns them 180 degrees so that the quick connector faces inwards and puts them back into the battery rack 4 for charging;

[0037] The bidirectional retractable battery pack gripper 11 grabs two more fully charged battery packs 5, turns them 180°, with the quick interface facing the heavy truck, and puts them into the battery mounting rack of the heavy truck to achieve battery replacement;

[0038] The stacker can accommodate three layers of battery packs 5 , and the battery racks 4 are arranged in a three-layer height array with a train track 2 at the bottom to accommodate forward, backward, left and right movement, grabbing battery packs 5 at different positions and providing heavy trucks with more battery energy storage.
