[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a lithium battery packaging structure, including a base 1, which is typically rectangular or square in shape and made of high-strength engineering plastic or metal. A battery box 2 is fixedly connected to the top of the base 1. The shape of the battery box matches the base 1, and its interior is designed with precise grooves to accommodate multiple separators 3. These separators 3 are made of insulating material, have regular shapes and precise dimensions to ensure effective isolation and protection when lithium batteries 4 are placed inside. The lithium batteries 4 are placed on top of the separators 3, and their bottoms are connected to the top of the battery box 2 via a specific locking structure to ensure that the batteries do not move or tilt during transportation and use. To further enhance safety, a protective shell 5 is detachably connected to the top of the battery box 2. This protective shell 5 is made of impact-resistant material, such as reinforced plastic or metal alloy, and has an internal elastic component providing resilience.

[0042] Multiple connecting plates 6 are fixedly connected to the top of the battery box 2. The shape and size of these connecting plates 6 are designed according to actual needs for connecting external devices or other components. Connecting rods 7 are fixedly connected to the outside of the connecting plates 6. These connecting rods 7 are typically made of metal and possess sufficient strength and rigidity. Follower blocks 8 are slidably connected to the outside of the connecting rods 7. These follower blocks 8 can slide freely on the connecting rods 7 and adjust their position as needed. Telescopic rods 10 are slidably connected inside the protective shell 5. These telescopic rods 10 are made of lightweight and high-strength materials, such as aluminum alloy or carbon fiber composite materials. The telescopic rods 10 can freely extend and retract within the protective shell 5 to adapt to different space requirements.

[0043] The other end of the telescopic rod 10 is fixedly connected to a sliding block 9, which can move smoothly under the guidance of the telescopic rod 10. To limit the range of movement of the telescopic rod 10 and ensure its stability, a limiting ring 11 is fixedly connected to the outside of the telescopic rod 10. The limiting ring 11 is made of a wear-resistant and corrosion-resistant material, such as stainless steel or hard plastic. The elastic assembly includes springs 12, which are fixedly connected inside the limiting ring 11, providing the necessary elasticity and cushioning for the entire structure. The springs 12 are externally slidably connected to the outside of the telescopic rod 10, sliding as the telescopic rod 10 extends and retracts, ensuring the flexibility and stability of the entire structure.

[0044] Reference Figure 2 , Figure 3 and Figure 6 Battery box 11 (2) is slidably connected to the top of battery box 11 (2). Battery box 11 (2) is made of a material compatible with battery box 11 (2), such as high-strength engineering plastic or aluminum alloy, to ensure the stability and durability of the overall structure. Its top is designed with a sliding groove, allowing the top cover 14 to slide smoothly on it. The top cover 14 is typically made of a lightweight and wear-resistant material, such as polycarbonate or ABS plastic, for ease of operation and to reduce overall weight. The top cover 14 is designed to provide additional protection against direct contact between external objects and the battery, while also facilitating user opening and closing. An opening slot 15 is fixedly connected internally to the base 1. The shape and size of the opening slot 15 are precisely designed according to actual needs to ensure that the sliding rod 16 can slide freely within it.

[0045] The edges of the slot 15 are smoothed to reduce wear and improve sliding smoothness. Multiple sliding rods 16 are slidably connected inside the slot 15. These sliding rods 16 are made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure sufficient strength and rigidity. The surfaces of the sliding rods 16 are polished to reduce friction and improve sliding efficiency. A circular plate 18 is fixedly connected to the outside of the sliding rods 16. The circular plate 18 is made of lightweight and high-strength materials, such as aluminum alloy or carbon fiber composite material. Its shape and size match the sliding rods 16 to ensure stable connection and transmission effect. Multiple springs 19 are provided inside the slot 15. These springs 19 provide the necessary elasticity and cushioning to prevent excessive impact on the sliding rods 16 during movement.

[0046] Spring 19 is typically made of high-carbon steel or alloy steel to ensure sufficient elasticity and durability. An electric push rod 20 is also fixedly connected inside the slot 15. The electric push rod 20 is an electromechanical device that uses a motor to drive the push rod's extension and retraction. It is fixedly connected inside the base 1 and connected to the sliding rod 16 via a suitable transmission mechanism for automated control. One end of spring 12 is fixedly connected inside the protective shell 5, and the other end is fixedly connected to the outside of the sliding block 9. This connection method allows spring 12 to provide continuous elastic force inside the protective shell 5, ensuring the tightness and stability of the entire structure. One end of the sliding rod 16 is fixedly connected to the outside of the circular plate 18, and the other end is fixedly connected to the outside of the push plate 17. The push plate 17 is typically made of wear-resistant materials, such as polytetrafluoroethylene or nylon, to reduce friction with the sliding rod 16 and improve transmission efficiency.

[0047] Working principle: First, multiple separators 3 are precisely placed in the grooves inside the battery box 2 to ensure effective isolation and protection when placing the lithium battery 4. Next, the lithium battery 4 is placed on top of the separators 3, and its bottom is connected to the top of the battery box 2 through a specific locking structure to ensure that the battery will not move or tilt during transportation and use. A protective shell 5 is detachably connected to the top of the battery box 2. By pressing the top cover 14, the telescopic rod 10 drives the sliding block 9 to quickly disassemble the connecting plate 6, which is equipped with an elastic component to provide flexibility. Multiple connecting plates 6 are fixedly connected to the top of the battery box 2. Connecting rods 7 are fixedly connected to the outside of the connecting plates 6. Follower blocks 8 are slidably connected to the outside of the connecting rods 7. Telescopic rods 10 are slidably connected inside the protective shell 5. A sliding block 9 is fixedly connected to the other end of the telescopic rods 10. A limit ring 11 is fixedly connected to the outside of the telescopic rods 10. The elastic component includes springs 12. These springs are fixedly connected inside the limit ring 11 to provide the necessary elasticity and buffering effect for the entire structure. The entire structure can be quickly and easily disassembled, making it convenient to take out and put in the lithium battery 4, easy to replace parts, improve transportation safety, and reduce the risk of damage.

[0048] When the forklift's fork arm enters the base 1, the movement of the fork arm drives the push plate 17 to perform a squeezing motion. The movement of the push plate 17 is further transmitted to the sliding rod 16, which is fixedly connected to it. The sliding rod 16 slides within the slot 15. Because the edges of the slot 15 are smoothed, this reduces wear and improves the smoothness of sliding. Multiple springs 19 are installed inside the slot 15. These springs provide the necessary elasticity and cushioning to prevent excessive impact on the sliding rod 16 during movement. The springs 19 are typically made of high-carbon steel or alloy steel. To ensure sufficient elasticity and durability, the electric push rod 20 is fixedly connected inside the base 1 and connected to the sliding rod 16 through a suitable transmission mechanism. The electric push rod 20 is driven by a motor to extend and retract, thereby automatically clamping the fork arm. One end of the spring 12 is fixedly connected inside the protective shell 5, and the other end is fixedly connected to the outside of the sliding block 9. This connection method allows the spring 12 to provide continuous elastic force inside the protective shell 5, thereby achieving a firm connection between the fork arm and the lithium battery 4 packaging structure, preventing the entire structure from shifting or tilting, and reducing the risk of damage.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
