[0024] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides an AGV intelligent scheduling robot, including a vehicle body 1, wheels 2 and a moving plate 3 on the vehicle body 1, and a track 4 for the movement of the vehicle body 1 at the bottom. The wheels 2 are installed in the vehicle body 1 and can move on the track 4 driven by the vehicle body 1, thereby scheduling and transporting objects through the vehicle body 1. A connecting rod 5 is fixedly installed in the vehicle body 1; the connecting rod 5 is equipped with a braking assembly for braking the wheels 2. By setting the braking assembly, the vehicle body 1 can cooperate with the vehicle body 1 to brake when braking. The vehicle body is equipped with a mechanical brake to brake the vehicle body 1, preventing the brake pads from wearing out too quickly when the vehicle body 1 relies solely on brake pads for braking. This avoids the vehicle body 1 increasing its braking distance due to excessively worn brake pads and failing to stop moving in time. The brake assembly includes a movable ring 6 on the connecting rod 5, a movable frame 7 fixedly connected to the movable ring 6, a push plate 8 on the movable frame 7, and a blocking block 9 on the push plate 8 to restrict the movement of the wheel 2. Between the blocking block 9 and the vehicle body 1, there are a push block 10 and a stop block 11 to gradually bring the blocking block 9 closer to the wheel 2.

[0025] like Figures 1 to 5 As shown, specifically, when the vehicle body 1 moves to a predetermined position on the track 4 and needs to brake to stop, a motor 12 is fixedly installed in the vehicle body 1. A threaded rod 13 is fixedly connected to the output shaft of the motor 12. The threaded rod 13 is threadedly connected to the moving plate 3, and the threaded rod 13 is rotatably connected to the connecting rod 5. A limit groove 14 is provided in the vehicle body 1, and the moving plate 3 is slidably connected in the limit groove 14. A connecting plate 15 for pushing the moving ring 6 is rotatably connected between the moving plate 3 and the moving ring 6. A long plate 16 is fixedly connected to the moving plate 3. A pressure plate 17 is fixedly connected to the push plate 8, and a spring 18 and a telescopic rod 19 are fixedly connected between the pressure plate 17 and the long plate 16. The vehicle body 1 starts the motor 12, which drives the threaded rod 13 to rotate, thereby causing the moving plate 3 to move downward in the limit groove 14. As the moving plate 3 moves downward, it drives the long plate 16 downward, thereby pushing the pressure plate 17 at the bottom end downward through the spring 18 and the telescopic rod 19. The moving frame 7 and the blocking block 9 are both provided with sliding grooves, and both ends of the push plate 8 are slidably connected in the sliding grooves. The downward movement of the pressure plate 17 can push the push plate 8 at the bottom end to move downward in the sliding groove in the moving frame 7. The downward movement of the push plate 8 can also push the blocking block 9 downward. The sliding groove can be set as a T-shaped groove, so that the push plate 8 can be limited and connected between the blocking block 9 and the moving frame 7. The blocking block 9 gradually moves downward and can move to the track 4 to make contact with it. After the blocking block 9 is in contact with the track 4, the blocking block 9 cannot move. As the moving plate 3 continues to move downward, the spring 18 and the telescopic rod 19 gradually contract and generate a reaction force.

[0026] like Figures 1 to 5As shown, specifically, as the aforementioned moving plate 3 continues to move downwards, the spring 18 and the telescopic rod 19 gradually contract and generate a reaction force. Simultaneously, the movement of the moving plate 3 causes it to push the moving ring 6 on the connecting rod 5 via the connecting plate 15, gradually moving it towards both ends of the connecting rod 5. This causes the moving ring 6 to push the moving frame 7. At this time, the moving frame 7 can push the push plate 8 to push the blocking block 9 closer to the side of the track 4. A tension spring 20 is fixedly connected between the blocking block 9 and the push plate 8, and the tension spring 20 is located in a groove. The blocking block 9 has an arc surface adapted to the wheel 2, and a protective pad is provided on the arc surface. The push block 10 is fixedly connected to the blocking block 9, and the stop block 11... Fixedly connected to the vehicle body 1, the push block 10 and the stop block 11 are both inclined at the same angle. As the blocking block 9 gradually approaches the side of the track 4, the blocking block 9 drives the top push block 10 to gradually approach the stop block 11 and apply pressure to it. Since the push block 10 and the stop block 11 are inclined at the same angle, the push block 10 gradually moves closer to the wheel 2 under the cooperation and contact between the push block 10 and the stop block 11. Then, the push block 10 drives the blocking block 9 to gradually move closer to the wheel 2 and gradually fit into the wheel 2. As the blocking block 9 gradually approaches the wheel 2, the push plate 8 moves in the groove in the blocking block 9, and the tension spring 20 is stretched and generates a reaction force. At this time, in the above process... The blocking block 9 contacts the bottom surface of the pushing rain track 4 and gradually approaches and contacts the wheel 2, thus limiting and blocking the wheel 2, causing the wheel 2 to stop rotating. Therefore, the braking effect of the blocking block 9, combined with the mechanical braking effect of the brake pads of the vehicle body 1, makes the braking effect of the wheel 2 better and reduces the wear of the mechanical brake pads. This makes the braking system of the entire vehicle body 1 better and increases the service life of the mechanical brake pads. Even after the mechanical brake pads are worn, the blocking block 9 can still limit and brake the wheel 2. When the braking is completed and the braking state is canceled, the reverse drive motor 12 causes the wheel 2 to move. When the moving plate 3 moves in the opposite direction and moves upward, it can drive the long plate 16 to move upward, so that the blocking block 9 can gradually disengage from the bottom surface of the track 4. The spring 18 and the telescopic rod 19 extend and reset under the reaction force of the spring 18. The upward movement of the moving plate 3 causes the moving ring 6 to move towards the middle of the connecting rod 5 through the connecting plate 15. The moving ring 6 pulls the blocking block 9 to move and reset through the moving frame 7 and the push plate 8. The blocking block 9 causes the push block 10 to separate from the stop block 11, so that the blocking block 9 moves and resets on the push plate 8 under the reaction force of the tension spring 20. That is, the blocking block 9 separates from the wheel 2 and cancels the blocking and limiting effect, so that the car body 1 can continue to move.
