[0002] As the world continues to pay attention to environmental protection and energy efficiency, the status of electric vehicle technology in the automotive industry has become increasingly prominent, especially in the field of commercial vehicles and heavy trucks. In contrast, electric heavy trucks have achieved the goal of zero tail gas emissions by adopting battery drive systems, while optimizing energy efficiency, which is of great significance for reducing carbon emissions and promoting sustainable development. However, although electrification technology has brought significant environmental benefits, it still faces several technical challenges and limitations at the specific application level; Therefore, new energy trucks are equipped with battery packs, and forklifts are needed to transfer the battery packs during loading and unloading. Since the position of the battery pack on the truck is relatively limited, the operation process is very cumbersome, and it is difficult to ensure the accuracy of the transportation position. Workers are required to manually adjust the installation position of the battery pack before installation, which requires a lot of manpower and material resources. In addition, during the transportation process, most of the battery packs are transported on pallets to prevent damage to the battery packs. However, there is no structure on the forklift to position it, resulting in the pallet and the battery pack being only in contact. When the forklift is bumpy, the battery pack will shift, which will cause more trouble during later loading and unloading. For this reason, we need to make improvements to this.

The forklift front shovel 1 is the basic structure of the forklift. When transporting the battery pack, the transportation method is driven by the forklift. This part of the structure is the existing technology and will not be elaborated in detail.

[0018] The multiple sets of lifting ring assemblies include an L-shaped plate 15 fixedly mounted on one side of the fixed platform 12, a hanging ring 14 is arranged on the upper surface of the L-shaped plate 15, and a movable clamping lifting ring 16 is arranged on the lower surface of the floating plate 3 and at the position corresponding to the hanging ring 14; Reference Manual Attached Figure 3 It can be seen that, under the movable sleeve of the hanging ring 14 and the lifting ring 16 , the floating plate 3 can swing left and right above the outside of the fixed platform 12 , and thus the battery pack can be fine-tuned when the battery pack is pushed forward.

[0019] The sliding assembly includes rails 4 respectively fixedly mounted on both sides of the upper surface of the floating plate 3, and slide seats 5 are slidably mounted outside the two sets of rails 4. A moving seat 19 is commonly arranged between the two slide seats 5. The support plate 6 is arranged on the upper surface of the support plate 6, and a push assembly is arranged on the outer side of the rear end of the moving seat 19; Reference Manual Attached Figure 1 and Figure 2 It can be seen that the slide seat 5 can drive the moving seat 19 to move outside the track 4, thereby ensuring that the push assembly is more stable when driving the moving seat 19 to move.

[0020] The push assembly includes a second hydraulic cylinder 22, the output end of the second hydraulic cylinder 22 is connected to the outer side of the rear end of the moving seat 19, and the outer side of the second hydraulic cylinder 22 away from the moving seat 19 is fixedly installed on the upper surface of the floating plate 3 through a fixed seat 17; Reference Manual Attached Figure 4 It can be seen that the second hydraulic cylinder 22 can drive the moving seat 19 to move toward the front end, thereby allowing the battery pack above the moving seat 19 to move toward the front end of the forklift front shovel 1.

[0021] A U-shaped platform 18 is arranged outside the rear end of the moving seat 19 and above the second hydraulic cylinder 22. A screw rod 21 is rotatably installed inside the U-shaped platform 18. A motor 32 is arranged at one end of the screw rod 21. The motor 32 is fixedly connected to the U-shaped platform 18. A slider 33 is threadedly matched on the outer side of the screw rod 21. The bottom of the slider 33 is slidably fitted with the upper surface of the U-shaped platform 18. Reference Manual Attached Figure 1 and Figure 4 It can be seen that the motor 32 drives the screw rod 21 to rotate, so that the slider 33 with the external thread moves horizontally on the upper surface of the U-shaped platform 18, thereby positioning the slider 33 and enabling the external structure of the slider 33 to be supported and positioned in the middle of the support plate 6.

[0022] The first hydraulic cylinder 20 is arranged inside the slider 33, and a positioning seat 23 is fixedly arranged at the telescopic end of the first hydraulic cylinder 20. Vertical rods 26 are symmetrically arranged inside the positioning seat 23, and movable components are arranged outside the two vertical rods 26 and inside the positioning seat 23; Reference Manual Attached Figure 4 It can be seen that the first hydraulic cylinder 20 can push the positioning seat 23 and the vertical rod 26 to move toward the middle of the interior of the support plate 6, thereby prompting the movable component to penetrate into the interior of the support plate 6 for positioning.

[0023] The movable assembly includes a clamping sleeve 27 fixedly sleeved on the outside of the vertical rod 26, a clamping arm 28 is fixedly arranged on the outside of the clamping sleeve 27, and a fixed shaft 29 is symmetrically arranged inside the clamping arm 28. Positioning wheels 30 are rotatably sleeved on both ends of the outer sides of the two fixed shafts 29. The positioning wheels 30 are polygonal prisms and are made of rubber material. The positioning wheels 30 are in contact with the top wall of the inner surface of the support plate 6; Reference Manual Attached Figure 5 and Figure 6 It can be seen that, under the connection of the clamping sleeve 27, the clamping arm 28 can install the positioning wheel 30 on the front end of the positioning seat 23. Under the drive of the first hydraulic cylinder 20, the positioning seat 23 and the positioning wheel 30 are allowed to penetrate into the interior of the pallet 6. When the positioning wheel 30 enters the interior of the pallet 6, the positioning wheel 30 contacts the top wall of the inner surface of the pallet 6. During the rolling and extrusion process, the cross-section of the positioning wheel 30 is against the pallet 6, thereby increasing the contact area with the pallet 6, thereby positioning the position of the pallet 6.

[0024] A pressure rod 11 is movably sleeved on the upper outer side of the vertical rod 26, and rubber blocks 25 are arranged at equal distances on the lower surface of the pressure rod 11 in the horizontal direction. A guide rod 7 is symmetrically arranged on the outer surface of the pressure rod 11, and a push rod 10 is slidably installed on the outer sides of the two guide rods 7. A connecting rod 31 is commonly arranged between the two groups of push rods 10, and a screw rod 24 is inserted through the internal thread of the connecting rod 31, and one end of the screw rod 24 is rotatably matched with the outer surface of the pressure rod 11; Reference Manual Attached Figure 1 , Figure 2 and Figure 5 It can be seen that when the screw rod 24 rotates, the connecting rod 31 will cause the push rods 10 at both ends to slide outside the guide rod 7, so that the push rods 10 can clamp the outside of the battery pack to ensure that the battery pack will not be displaced during transportation; The multiple groups of rubber blocks 25 on the lower surface of the pressure rod 11 can make the rubber blocks 25 contact with the upper surface of the battery pack when the pressure rod 11 slides down to the outside of the vertical rod 26, so that the pressure rod 11 can be tightly attached to the battery pack.

[0025] Working principle: When in use, when the battery pack is placed on the top of the pallet 6, the worker can lift the two pressure rods 11. After the battery pack is placed on the upper surface of the pallet 6, the screw 24 is driven to rotate, so that the screw 24 can drive the connecting rod 31 and the push rod 10 to the outside of the battery pack, so that one side of the push rod 10 is in contact with the battery pack. After the battery pack is fixed, under the connection of the clamping sleeve 27 and the clamping arm 28, the first hydraulic cylinder 20 drives the positioning seat 23 to move to the front end, causing the polygonal positioning wheel 30 to roll to the groove of the pallet 6. During the rolling process of the polygonal positioning wheel 30, one of the cross sections is in elastic contact with the top wall of the inner surface of the pallet 6, thereby increasing the contact area between the positioning wheel 30 and the pallet 6, ensuring that the pallet 6 can be stably It is fixedly arranged on the upper surface of the floating flat plate 3 for use. When loading and unloading the battery pack, the second hydraulic cylinder 22 drives the moving seat 19 to move toward the front end of the track 4, and then pushes the battery pack to the front end, so that the battery pack can be pushed in from the front end of the forklift front shovel 1, and then the push rod 10 is moved away from both sides of the battery pack, and the pressure rod 11 is rotated to be parallel to the vertical rod 26. The forklift front shovel 1 moves to the front end according to the position of the battery assembly on the truck, lifts the battery pack, and the floating flat plate 3 goes deep into the bottom of the truck to slowly push the battery pack. When the battery pack is pushed onto the truck, the left and right floating of the lifting ring assembly can be used to finely adjust the position of the battery pack entering the truck. This brings great convenience to people both during transportation and loading and unloading.

[0026] It is worth noting that the floating platform of the present invention can be used in conjunction with a forklift. The floating platform is installed on the fork of the forklift, and the battery pack placed on the floating platform is transported to the desired location by the movement of the forklift. At the same time, it can also be used in conjunction with other devices, such as battery-swapping AGVs, various battery-swapping devices, etc., as a battery pack carrier platform for replacing batteries for new energy trucks.
