[0002] In the current era of rapid automation in the warehousing and logistics industry, multi-directional AGVs (Automated Guided Vehicles) are widely used. As a key component, the AGV's casters play a decisive role in enabling flexible and efficient material handling operations. However, in actual warehousing environments, various impurities and tiny particles inevitably exist on the ground. With frequent AGV operation, these impurities easily accumulate along the caster's path. On one hand, when impurities enter the contact area between the tire and the ground, they increase tire wear, reduce tire lifespan, and frequent tire replacements not only increase costs but also affect the continuity of warehousing operations. On the other hand, impurity accumulation can cause the casters to roll poorly, affecting the stability and accuracy of AGV operation, making it difficult for the AGV to travel precisely along the preset path, and reducing material handling efficiency. Summary of the Invention

Inclined connecting brackets are welded to the ends of both metal fixing rods away from the screw fixing plates. Both inclined connecting brackets are set at an inclined angle of front-down and rear-up. An integrated strip is connected between the front ends of the two inclined connecting brackets. The bottom outer wall of the integrated strip is densely covered with cleaning bristles.

[0006] Preferably, the integrated strip can be fixedly connected to two inclined connecting brackets by screws. The integrated strip is located on the lower front side of the U-shaped fixing bracket, and the integrated strip is also located at the bottom front of the tire and the wheel hub.

[0007] Preferably, anti-detachment rings are fitted and fixed to the outer ends of the two wheel axles away from the wheel hub, and anti-detachment rings are also fitted and fixed to the outer ends of the two connecting shafts away from the U-shaped fixing frame. The anti-detachment rings can prevent the front and rear ends of the shock-absorbing connecting swing arm from detaching from the outside of the connecting shaft and the wheel axle, respectively.

[0008] Preferably, both ends of the shock-absorbing connecting swing arm can rotate outside the connecting shaft and wheel shaft respectively through the shaft hole, and both ends of the two shock-absorbing connecting swing arms are treated with semi-circular arc surfaces.

[0009] Preferably, a support block is welded to the top of each of the two connecting pieces, the two support blocks extend horizontally to the left and right respectively, and shock-absorbing springs are connected between the two support blocks and the bottom ends of the two rear corners of the top plate of the moving wheel.

[0010] Preferably, metal plates are welded to both the upper and lower ends of the shock-absorbing springs, and the metal plates at both ends of the two shock-absorbing springs are fixedly connected to the top plate of the moving wheel and the two support blocks by screws.

Detailed Implementation

[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] This utility model provides a shock-absorbing and guiding structure for a multi-directional AGV (Automated Guided Vehicle) caster wheel, as shown in Figures 1-6. It includes a top plate 10 for the caster wheel and a U-shaped fixing frame 9 fixed to the bottom front end of the top plate 10. The U-shaped opening of the fixing frame 9 faces downwards. The top plate 10 plays a crucial role in the overall AGV caster wheel structure, providing a reference plane for the installation of other components and ensuring accurate relative positions between them. The U-shaped fixing frame 9 is securely installed at the bottom front end of the top plate 10. Its downward-facing U-shaped opening not only provides specific installation space for the hub 2 and subsequent components, but this structural form also enhances the overall... The stability of the body connection effectively resists the various forces generated during AGV operation, ensuring the stability and reliability of the entire universal wheel system. A hub 2 is installed inside and behind the opening of the U-shaped fixing frame 9. The hub 2 is located below the center of the top plate 10 of the moving wheel. A tire 1 is fixedly fitted onto the circular outer wall of the hub 2. The hub 2 serves as the mounting carrier for the tire 1, tightly fitted and fixed to the tire 1, providing the tire 1 with a central axis of rotation. A wheel axle 4 is installed at the center of both ends of the hub 2. A connecting piece 3 is fitted onto the outside of each wheel axle 4. A shock-absorbing connecting arm 6 is installed on the outside of each connecting piece 3. Both shock-absorbing connecting arms 6 extend forward. Both ends of the rear section have internal shaft holes, and the internal shaft holes of the two shock-absorbing connecting swing arms 6 are fitted onto the outside of the wheel axle 4. Connecting shafts 8 are located on the lower side of the center of the outer walls at both ends of the U-shaped fixing frame 9. The internal shaft holes of the two front ends of the two shock-absorbing connecting swing arms 6 are respectively fitted onto the outside of the two connecting shafts 8. Anti-detachment rings are fitted and fixed to the outside of the ends of the two wheel axles 4 away from the hub 2. Anti-detachment rings are also fitted and fixed to the outside of the ends of the two connecting shafts 8 away from the U-shaped fixing frame 9. The anti-detachment rings prevent the front and rear ends of the shock-absorbing connecting swing arms 6 from detaching from the connecting shafts 8 and wheel axles 4 respectively. Both the front and rear ends of the shock-absorbing connecting swing arms 6 can rotate through the shaft holes on the outside of the connecting shafts 8 and wheel axles 4 respectively. Both ends of the shock-absorbing connecting swing arm 6 are treated with semi-circular arc surfaces. This ingenious connection method gives the shock-absorbing connecting swing arm 6 the ability to rotate flexibly on the shaft, allowing the tire 1 to swing and turn in multiple directions, thus realizing the multi-directional movement function of the warehouse AGV universal wheel. At the same time, anti-detachment rings are fitted and fixed at the ends of the wheel axle 4 and the connecting shaft 8 away from the relevant components. These anti-detachment rings play a crucial safety role, effectively preventing the front and rear ends of the shock-absorbing connecting swing arm 6 from detaching from the outside of the connecting shaft 8 and the wheel axle 4, respectively, ensuring that the entire wheel connection structure remains stable in complex operating environments and avoiding equipment failure caused by component detachment.

[0025] As shown in Figures 1, 2, 3, and 4, support blocks 5 are welded to the top of each of the two connecting plates 3. The two support blocks 5 extend horizontally to the left and right, respectively. Shock-absorbing springs 12 are connected between the two support blocks 5 and the bottom ends of the two rear corners of the moving wheel top plate 10. Metal plates are welded to both the upper and lower ends of the shock-absorbing springs 12. The metal plates at both ends of the two shock-absorbing springs 12 are fixedly connected to the moving wheel top plate 10 and the two support blocks 5 by screws. To effectively buffer the vibration and impact forces from the ground experienced by the AGV during operation, support blocks 5 extending horizontally to the left and right are welded to the top of each of the two connecting plates 3. These two support blocks 5 are connected to the bottom ends of the two rear corners of the moving wheel top plate 10 by screws. A shock-absorbing spring 12 is connected between the AGV and the swivel wheel. Metal plates are welded to both the upper and lower ends of the shock-absorbing spring 12, and the metal plates are firmly fixed to the top plate 10 of the swivel wheel and the two support blocks 5 by screws. When the swivel wheel travels on uneven ground or encounters other vibration sources, the shock-absorbing spring 12 will undergo elastic deformation. Through this elastic deformation, the shock-absorbing spring 12 can absorb and disperse vibration energy, reduce the direct transmission of vibration to the AGV body, and thus effectively reduce the vibration amplitude of the vehicle body, providing a strong guarantee for the stable operation of the AGV. This shock-absorbing design not only improves the stability of the AGV during travel, but also reduces the wear of equipment parts caused by vibration and extends the service life of the equipment.

[0026] As shown in Figures 1, 2, 3, and 4, a guide mechanism 11 is provided at the center of the top of the movable wheel top plate 10. A fixed top plate 13 is provided at the top of the guide mechanism 11. Screw holes are provided inside the fixed top plate 13 near the four corners. The guide mechanism 11 is composed of an anti-detachment fixing baffle 14, a bearing hole 15, a metal guide shaft 16, a guide bearing 17, and a bearing seat 18. The bearing seat 18 is fixed to the center of the bottom end of the fixed top plate 13 by multiple embedded screws. The bearing seat 18 has a bearing hole 15 inside, with the opening of the bearing hole 15 facing downwards. A guide screw is provided inside the bearing hole 15. A detachment fixing plate 14 is fixed to the bottom of the bearing 17 and bearing housing 18 by embedded screws. The detachment fixing plate 14 has a through hole at its center. A metal guide shaft 16 is welded to the center of the top of the moving wheel top plate 10. The top of the metal guide shaft 16 passes through the through hole inside the detachment fixing plate 14 and is fixed in the guide bearing 17. The guide bearing 17 can rotate clockwise and counterclockwise outside the metal guide shaft 16. The guide mechanism 11 set at the center of the top of the moving wheel top plate 10 is the core component for achieving precise guidance of the warehouse AGV's universal wheels. The bearing housing 18 is secured by multiple embedded screws. The guide bearing 17 is fixedly located at the bottom center of the fixed top plate 13. Its internal bearing hole 15 faces downwards, providing a precise installation position for the guide bearing 17. The guide bearing 17 is installed inside the bearing hole 15 and can rotate flexibly within it. An anti-detachment fixing plate 14 is fixed to the bottom of the bearing seat 18 by an embedded screw. This plate has a through hole at its center. A metal guide shaft 16, welded to the top center of the moving wheel top plate 10, passes through the through hole inside the anti-detachment fixing plate 14 and is precisely fixed in the guide bearing 17. This structural design allows the guide bearing 17 to... The metal guide shaft 16 rotates freely clockwise and counterclockwise outside. During the actual operation of the warehouse AGV, the rotation direction and angle of the guide bearing 17 can be precisely controlled by external control signals and the corresponding guidance control system. Due to the relative rotation between the guide bearing 17 and the metal guide shaft 16, the entire caster wheel is driven to turn and move in the preset direction. This enables the warehouse AGV to accurately travel to the designated position in the complex warehouse environment according to different task requirements and path planning, which greatly improves the efficiency and accuracy of automated warehouse logistics operations.

[0027] As shown in Figures 1, 5, and 6, a displacement-following cleaning device 7 is connected to the two shock-absorbing connecting arms 6. The displacement-following cleaning device 7 includes screw fixing plates 19, metal fixing rods 20, inclined connecting brackets 21, integrated strips 22, and cleaning bristles 23. Screw fixing plates 19 are fixed to the middle section of the outer wall of each of the two shock-absorbing connecting arms 6. Metal fixing rods 20 are welded to the center of the outer wall of each of the two screw fixing plates 19. Inclined connecting brackets 21 are welded to the ends of each of the two metal fixing rods 20 away from the screw fixing plates 19. The two inclined connecting brackets 21 are set at an incline angle of front-down and rear-up. An integrated strip 22 is connected between the front ends of the two inclined connecting brackets 21. The outer wall of the bottom end of the integrated strip 22 is densely covered with cleaning bristles. 23. The displacement follow-up cleaning device 7 is tightly connected to the shock-absorbing connecting arm 6 via a screw fixing plate 19. The screw fixing plate 19 is firmly installed in the middle section of the outer wall of the two shock-absorbing connecting arms 6, providing a reliable installation base for the entire cleaning device. The metal fixing rod 20 welded on the screw fixing plate 19 connects the screw fixing plate 19 to the inclined connecting bracket 21, so that the cleaning device can move with the movement of the shock-absorbing connecting arm 6. Since the shock-absorbing connecting arm 6 can swing flexibly under the action of the wheel axle 4 and the connecting shaft 8, this connection method ensures that the displacement follow-up cleaning device 7 can follow the movement and turning of the universal wheel in real time and always stay in the appropriate position to achieve cleaning of specific areas.

[0028] As shown in Figures 1, 5, and 6, the integrated strip 22 can be fixedly connected to the two inclined connecting brackets 21 by screws. The integrated strip 22 is located on the lower front side of the U-shaped fixing frame 9, and is also located in front of the bottom of the tire 1 and the wheel hub 2. When the bottom of the tire 1 contacts the ground, multiple cleaning bristles 23 simultaneously contact the ground. The two inclined connecting brackets 21 are set at an angle of front-down and rear-up. This design is significant because it ensures that the integrated strip 22, connected to the front end of the two inclined connecting brackets 21, is located on the lower front side of the U-shaped fixing frame 9 and in front of the bottom of the tire 1 and the wheel hub 2. When the bottom of the tire 1 contacts the ground and operates normally, the densely packed cleaning bristles 23 at the bottom of the integrated strip 22 also simultaneously contact the ground, ensuring that the cleaning bristles 23 can effectively contact the ground, thus providing the necessary cleaning for removing impurities from the ground. The integrated strip 22 is securely connected to the two inclined connecting brackets 21 by screws, ensuring the stability of the structure. During the forward movement of the AGV's universal wheels, the displacement follow-up cleaning device 7 is always in front of the moving wheels due to its follow-up relationship with the shock-absorbing connecting swing arm 6. At this time, the cleaning bristles 23 at the bottom of the integrated strip 22 generate relative movement with the ground. Utilizing the soft material and dense arrangement of the cleaning bristles 23, it can effectively clean obstacles such as particulate impurities on the ground. These cleaning bristles 23 can sweep the debris aside, preventing impurities from accumulating on the universal wheel's travel path and avoiding impurities from entering the contact area between the tire 1 and the ground, thereby reducing tire 1 wear and improving tire 1 service life. At the same time, it also ensures the smooth movement of the universal wheels and improves the stability and accuracy of the AGV's operation.
