[0023] 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.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automated guided vehicle (AGV) for warehouses, including a lifting rack 2. A four-way drive seat 1 is provided on the lower surface of the lifting rack 2, providing multi-directional movement capability for the lifting rack 2. This allows the lifting rack 2 to flexibly adjust its position in different directions for accurate goods handling. A connecting box 3 is fixedly connected inside the four-way drive seat 1. The connecting box 3 acts as an intermediate connecting structure, connecting the four-way drive seat 1 with other components, integrating different parts together to make the entire system more compact and stable. A U-shaped plate 11 is fixedly connected to the upper surface of the connecting box 3. Plate 11 provides an installation position for motor 5, ensuring the secure and stable installation of motor 5. Motor 5 is fixedly connected to the inner wall of U-shaped plate 11. Motor 5 is the power source for the entire lifting assembly, providing power for the lifting operation of goods through its rotation. Lifting assembly is set at the output end of motor 5. Lifting assembly is used to drive the goods to lift and lower, realizing the vertical position adjustment of goods, facilitating the loading, unloading and transportation of goods. Lifting assembly includes threaded rod 7, which is fixedly connected to the output end of motor 5. Driven by motor 5, it rotates, converting the rotational motion of motor 5 into a power transmission source for linear motion. The outer wall of the threaded rod 7 is rotatably connected to the inside of the connecting box 3, ensuring smooth rotation of the threaded rod 7 within the connecting box 3, while providing support and guidance for subsequent movements. A movable block 8 is threadedly connected to the outer wall of the threaded rod 7. The threaded connection between the movable block 8 and the threaded rod 7 allows the movable block 8 to move linearly along the axial direction of the threaded rod 7 when the threaded rod 7 rotates, achieving a lifting function. One side of the outer wall of the movable block 8 is fixedly connected to one side of the outer wall of the lifting rack 2, transmitting the lifting motion of the movable block 8 to the lifting rack 2, thus driving the lifting rack 2 to perform lifting operations. A slider 9 is fixedly connected to one side of the outer wall of the movable block 8. The slider 9 is connected to the movable block... The movement of the movable block 8 together provides additional stability for its linear movement. The connecting box 3 has a slide groove 4 inside, which provides a sliding track for the slider 9, restricting the movement direction of the slider 9 so that it can only move in a set linear direction. The outer wall of the slider 9 is slidably connected to the inner wall of the slide groove 4, ensuring that the linear movement of the slider 9 and the movable block 8 is more stable and preventing deviation and shaking during the movement. A baffle 6 is fixedly connected to the upper surface of the lifting rack 2. The baffle 6 is used to limit the goods and prevent the goods from sliding or falling on the lifting rack 2 for various reasons, ensuring the safety of the goods during the handling process.

[0025] Reference Figure 1 and Figure 4A fixed plate 12 is fixedly connected to the upper surface of the four-way drive seat 1. The fixed plate 12 serves to fix and support other components, providing a stable foundation platform for the installation of subsequent components and ensuring the integrity and stability of the entire system structure. A slider 15 is installed inside the fixed plate 12. As a movable component, the slider 15 provides a basis for the relative movement of other components. It can move within a certain range within the fixed plate 12, helping to achieve certain functions of the system. A limiting roller 13 is rotatably connected inside the slider 15. The limiting roller 13 can rotate within the slider 15. During loading, when the goods come into contact with the limiting roller 13, it can roll, reducing the friction between the goods and the slider 15, allowing the goods to move more smoothly to a certain extent. It also plays a certain limiting and guiding role, preventing excessive deviation of the goods in a certain direction. A sliding rod 16 is slidably connected inside the limiting roller 13. The sliding rod 16 slides within the limiting roller 13, and its position can be adjusted according to the pushing of the goods or other external forces. It can cooperate with other components to achieve control over the position of the limiting roller 13. Precise control ensures that the limiting roller 13 functions in the appropriate position under different working conditions. A spring 17 is sleeved on the outer wall of the slide rod 16, which acts as a buffer and reset mechanism. A second slide groove 14 is opened inside the fixed plate 12, which provides a sliding track for the second slider 15, limiting the movement path of the second slider 15 and ensuring that the second slider 15 can only move in the predetermined direction. This ensures the accuracy and stability of the system's movement and prevents the second slider 15 from deviating from the predetermined trajectory. An auxiliary plate 10 is fixedly connected to one side of the outer wall of the four-way drive seat 1. The auxiliary plate 10 provides auxiliary support or guidance for loading and handling goods, making it easier for goods to enter the lifting rack 2. This ensures a more accurate positional relationship between the goods and the lifting rack 2, improving the efficiency and accuracy of goods handling. A connecting ring 18 is fixedly connected to the outer wall of the limiting roller 13. The connecting ring 18 is used to connect other components or transmit forces, connecting the limiting roller 13 to other components. This allows the forces between the components to be transmitted through the connecting ring 18, ensuring that the coordinated actions between the components can be carried out in an orderly manner during the operation of the entire system.

[0026] Working principle: When goods need to be moved, the operator first controls the moving trolley to move so that the lifting rack 2 is accurately aligned with the bottom of the goods. At this time, due to the setting of the auxiliary plate 10 on the outside of the four-way drive seat 1, as the moving trolley continues to move forward, the goods will gradually rise along the slope of the auxiliary plate 10 until they are completely loaded onto the lifting rack 2, and the goods can be moved.

[0027] After the goods are loaded, the motor 5 can be started. The motor 5 can drive the threaded rod 7 to rotate, and the threaded rod 7 can drive the moving block 8 connected to it to move. At this time, through the sliding setting of the slider 9 and the slide groove 4, the moving block 8 can make linear lifting and lowering motion within the connecting box 3. When the moving block 8 moves, it will drive the lifting rack 2 on its outer side to move, thereby realizing the lifting and lowering of the lifting rack 2. At the same time, the baffle 6 set above the lifting rack 2 can limit the goods and effectively prevent the goods from shifting during the handling process. After the goods are handled, the four-way drive seat 1 can complete the handling operation of the goods.

[0028] During the loading process, the cargo will press against the limiting roller 13. At this time, the limiting roller 13 will rotate under the support of the second slider 15. Through the sliding setting of the slide rod 16 and the second slider 15, the limiting roller 13 can push the second slider 15 to slide along the outer wall of the slide rod 16. At the same time, the spring 17 will also be compressed and contracted. Then, through the elastic reaction force of the spring 17, the limiting roller 13 will apply a reverse pushing force to the cargo, thereby pushing the cargo back to the correct position. This achieves automatic alignment of the cargo, effectively preventing the cargo from shifting during the handling process and ensuring the stability and safety of cargo handling.

[0029] 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.
