[0033] In the energy storage sector, loading battery packs into containers places high demands on the handling trolley's flexibility, load capacity, and telescopic and lifting precision. Traditional forklifts for transporting PACK modules into containers require high operator skills and high lifting precision. During actual handling, the modules can easily collide with the container's left and right limit plates and height partitions, causing deformation. Therefore, there is an urgent need for a transporting device with high transverse, telescopic, and lifting precision to load battery packs into containers.

[0034] The present application discloses a battery pack loading device, which is used to transport pack battery packs so that they can cross obstacles and pass through openings for transplanting operations, and finally the pack battery packs can be smoothly stacked in a container under complex working conditions. The device has high flexibility and high precision. When the battery pack enters the container, it will not collide with the left and right side walls of the container, thereby avoiding damage to the battery pack or the container.

[0035] The following combination Figures 1 to 6 This section describes the structure and working principle of the battery pack boxing equipment. Figure 1 As shown, the battery pack boxing equipment includes a transferring trolley 1, a lifting module 2 and a pallet assembly 3. The lifting module 2 is arranged on the transferring trolley 1, and the pallet assembly 3 is arranged at the driving end of the lifting module 2, that is, the lifting module 2 can drive the pallet assembly 3 to move in the vertical direction, and adjust the height of the pallet assembly 3 according to the height of different storage ports of the container. The transferring trolley 1 is configured to drive the lifting module 2 and the pallet assembly 3 to move, and move between the loading point of the battery pack boxing equipment and the storage port relative to the container.

[0036] See Figure 1As shown, the transplanting trolley 1 includes a frame 11, a pulley 12, a battery module and an electric control box (the battery module and the electric control box are not shown in the figure), the pulley 12 is connected to the frame 11, wherein an installation space 13 is provided in the middle of the frame 11, and the installation space 13 is opened above. The lifting module 2 is arranged in the installation space 13, and the opening on the installation space 13 can avoid interference with the movement of the lifting module 2. A accommodating space is provided on both sides of the installation space 13, and the battery module and the electric control box are respectively arranged in a accommodating space.

[0037] Preferably, anti-collision strips 14 are provided around the upper edge of the frame 11. The anti-collision strips 14 protrude outward relative to the frame 11. When contacting other objects, the anti-collision strips 14 contact the objects first, which can prevent the frame 11 from being damaged. In addition, diagonal avoidance detectors are provided on the diagonal sides of the frame 11, which can monitor obstacles and avoid them to reduce the impact on the frame 11.

[0038] See Figure 3 As shown, in the embodiment, the lifting module 2 includes a mounting base 21, a driving member 22, a double scissor fork 23 and a mounting table 24. The mounting base 21 is arranged in the mounting space 13, the driving member 22 is arranged on the mounting base 21, and the two ends of the double scissor fork 23 are respectively connected to the mounting base 21 and the mounting table 24. The driving member 22 adjusts the height of the mounting table 24 relative to the mounting base 21 by driving the double scissor fork 23 to extend and retract. When the distance between the mounting table 24 and the mounting base 21 is the shortest, the mounting table 24 can be completely immersed in the mounting space 13, and the battery pack can be loaded relative to the tray assembly 3. At this time, it provides great convenience for the storage or transportation of the battery pack into the box structure.

[0039] The tray assembly 3 is used to carry the battery pack and push the battery pack into the container. Figure 4 As shown, in this embodiment, the tray assembly 3 may include a base plate 31, a connecting plate 32, a carrier plate 34, and a push plate 35. The connecting plate 32 is mounted on the base plate 31 and slides in a first direction. The carrier plate 34 is mounted on the connecting plate 32 and slides in a second direction. The push plate 35 is mounted on the carrier plate 34 and is capable of sliding in the first direction to push the battery pack into the container. Compared to the prior art, the battery pack is placed on the tray assembly 3, wherein the carrier plate 34 is capable of sliding in the second direction and the connecting plate 32 is capable of sliding in the first direction. Because the carrier plate 34 is mounted on the connecting plate 32, it can move in the first direction along with the connecting plate 32. That is, the battery pack on the tray assembly 3 can automatically align with the container's entry port in the horizontal plane to prevent deformation caused by collision between the left and right limit plates and the height partitions.

[0040] Preferably, the connecting plate 32 and the bottom plate 31 are connected in a sliding manner via a slide rail. The tray assembly 3 further comprises a first transporting drive member 331, which is arranged on the side of the bottom plate 31 away from the connecting plate 32, i.e., below the bottom plate 31. A first avoidance slot 332 is provided on the bottom plate 31. The driving end of the first transporting drive member 331 passes through the first avoidance slot 332 and is connected to the connecting plate 32. The connecting plate 32 is driven to slide in the first direction by the first transporting drive member 331. Figure 1 In the embodiment, the X direction is defined as the first direction and the Y direction is defined as the second direction.

[0041] Furthermore, the connecting plate 32 and the carrier plate 34 are connected in a sliding manner in the second direction via a slide rail. The sliding of the carrier plate 34 relative to the connecting plate 32 is driven by a second transporting driver 333. The connecting plate 32 is provided with a strip hole 334. The second transporting driver 333 is locked in the strip hole 334. Its driving end is connected to the carrier plate 34. The second transporting driver 333 is provided below the connecting plate 32 and is used to drive the carrier plate 34 to move in the second direction. The bottom plate 31 is provided with an avoidance opening below the second transporting driver 333 to prevent interference with the second transporting driver 22. In an embodiment, both the first transporting driver 331 and the second transporting driver 333 may include a screw structure, which is a conventional drive mechanism.

[0042] Furthermore, support plates 38 are provided on both sides of the carrier plate 34, and balls 39 that can rotate relative to the support plates 38 are provided on the support plates 38. Multiple groups of balls 39 work together to support the battery pack, pushing the battery pack so that it gradually breaks away from the support of the tray assembly 3 and slides towards the container. The process is subject to rolling friction, thereby reducing the friction between the two.

[0043] Furthermore, the battery pack boxing device also includes a limiting member to limit the position of the battery pack on the tray assembly 3, see Figure 1 As shown, the limiting member includes fixed limiting plates 36 provided on both sides of the carrier plate 34, and the fixed limiting plates 36 on both sides are arranged opposite to each other, and also includes a movable limiting plate 371, which can be raised and lowered relative to the carrier plate 34, and is arranged opposite to the push plate 35. The fixed limiting plate 36, the movable limiting plate 371 and the push plate 35 cooperate with each other to form a accommodating space, and the battery pack is arranged in the accommodating space.

[0044] Specifically, a notch is provided on any fixed limiting plate 36 , which divides the fixed limiting plate 36 into several sections. The notches correspond to each other, providing a clearance for the battery pack to be loaded relative to the push plate assembly.

[0045] In this embodiment, two groups of movable limit plates 371 are provided, and the movable limit plates 371 are driven to rise and fall by a driving motor 376. The structures and working principles of the two movable limit plates 371 and the driving motor 376 are the same. Here, any one movable limit plate 371 is taken as an example for description.

[0046] Specifically, a U-shaped groove 372 is provided at the end of the bottom plate 31, and a movable limit plate 371 is provided in the U-shaped groove 372. A blocking portion 373 is provided on both sides of the U-shaped groove 372. The blocking portion 373 can keep the movable limit plate 371 from separating from the U-shaped groove 372 in the first direction. A strip groove 374 is obliquely provided on the movable limit plate 371, and the driving end of the driving motor 376 is connected to a cylindrical slider 375. The other end of the cylindrical slider 375 extends into the strip groove 374. The driving motor 376 drives the cylindrical slider 375 to slide in the second direction. Since the strip groove 374 is obliquely provided, the movable limit plate 371 will move in the vertical direction during the sliding process of the cylindrical slider 375.

[0047] When the movable limiting plate 371 is lowered to the lowest position, its upper side surface and the upper side surface of the U-shaped slide 372 are lower than the support surface formed by the ball 39, and the battery pack will not be blocked when being pushed into the container.

[0048] Preferably, the push plate 35 is connected to the carrier plate 34 via two parallel slide rails, and is driven by a push plate driver to slide the push plate 35 relative to the carrier plate 34 in a first direction. Limiting frames are provided on both sides of the push plate 35. When the battery pack is positioned on the carrier plate 34, it is positioned within the limiting frames. After the battery pack is loaded onto the carrier plate 34, the push plate driver drives the push plate 35 toward the movable lifting plate, allowing one side of the battery pack to abut against the movable limiting plate 371. The limiting frames mentioned above are intended to ensure that the battery pack does not deviate during the pushing process. In this embodiment, the notch in the fixed limiting plate 36 divides the fixed limiting plate 36 into several sections, and the two sides of the end near the movable limiting plate 371 are unobstructed. When the battery pack is pushed away from the obstruction of the fixed limiting plate 36, the limiting frames ensure that the battery pack is pushed without deflection, thereby preventing the battery pack from being scratched by the side of the container during the loading process. In this embodiment, the push plate driver 22 may include a rotary motor, a reduction motor, and a screw structure, which is a conventional drive method.

[0049] Implementation principle: When the battery pack is loaded relative to the container, first, the battery pack is placed on the carrier plate 34, and then the push plate driving member drives the push plate 35 to push the battery pack toward the movable baffle until one side of the battery pack is against the movable limit plate 371. At this time, the movable limit plate 371 is in a raised state; then, the transfer trolley 1 moves to the corresponding position of the container opening to be stored, the lifting module 2 drives the tray assembly 3 to drive the battery pack to rise to the corresponding storage position, the carrier plate 34 drives the battery pack to fine-tune its position relative to the bottom plate 31, the movable limit plate 371 descends, and the push plate 35 pushes the battery pack into the container.

[0050] The above is only a preferred embodiment of the battery module transport mechanism disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
