[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 ,in, Figure 1 A schematic diagram of a preferred embodiment of the practical mobile sorting robot provided by this utility model; Figure 2 for Figure 1 The diagram shows the left-view structure. Figure 3 for Figure 2 The diagram shows a partial sectional view. Figure 4 for Figure 3 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 2 The front sectional view shown is illustrated. Figure 6 for Figure 5 The enlarged schematic diagram of section B is shown below; Figure 7 for Figure 5 The enlarged schematic diagram of section C is shown below; Figure 8 for Figure 5The diagram shows an enlarged view of part D. A practical mobile sorting robot includes: a robot body 1, with drive wheels 11 symmetrically mounted on the bottom of the robot body 1; auxiliary wheels 12 arranged around the outer perimeter of the robot body 1; movable components 2 arranged on the left and right sides of the robot body 1; and positive resistance components 3 arranged at the bottom of each movable component 2. Each positive resistance component 3 includes a support plate 31, which is mounted on the bottom of the movable component 2. A through hole 32 is formed inside the support plate 31, and a circular plate 33 is slidably connected inside the through hole 32. A straight rod 34 is fixedly connected to the bottom of the circular plate 33. An elastic element 35 is sleeved on the outside of the straight rod 34. A circular hole block 36 is provided at the bottom of the through hole 32 to prevent the circular plate 33 from sliding out of the through hole 32. The straight rod 34 passes through the circular hole block 36 and extends to its outside. An inclined plate 37 is fixedly connected to the output end of the straight rod 34. A rubber strip 38 is provided at the top of the inclined plate 37. The top of the rubber strip 38 is slidably connected to the outside of the drive wheel 11. A silicone pad 39 is installed at the bottom of the inclined plate 37. An extension component 4 is provided on the top of the robot body 1. A reset component 5 is provided on the outside of each extension component 4.

[0019] The robot body 1 can move through the active wheel 11. The auxiliary wheels 12 are distributed around the outside of the robot body 1 to help the active wheel 11 maintain the robot's balance and stability. The active component 2 can restrict the active wheel 11 in the event of a collision. The silicone pad 39 can increase friction when the straight rod 34 extends and contacts the ground.

[0020] The movable component 2 includes a movable part 21, which is installed on the left and right sides of the robot body 1. A connecting part 22 is rotatably connected to the outside of the movable part 21. A short column 23 is movably connected to the end of the connecting part 22. An arched frame 24 is fixedly connected to the top of the short column 23. The bottom of the arched frame 24 is fixedly connected to the top of the support plate 31.

[0021] The movable part 21 is connected to the connecting part 22 via external rotation, which can flexibly adjust the angle and position, thereby changing the position of the bow frame 24 on the short column 23. Under the coordinated action of the movable part 21 and the connecting part 22, the position of the positive resistance component 3 can be changed, so as to better cope with collision impacts from different directions and ensure the stable operation of the robot.

[0022] The extension component 4 includes a rotating shaft 41, which is mounted on the top of the robot body 1. A synchronization block 42 is rotatably connected to the outside of the rotating shaft 41. A circular tube 43 is fixedly connected to the outside of the synchronization block 42. A compression spring 44 is provided inside the circular tube 43. A circular rod 45 is slidably connected inside the circular tube 43. A rotating wheel 46 is provided at the end of the circular rod 45. The outer surface of the rotating wheel 46 is slidably connected to the inner side of the bow-shaped frame 24.

[0023] By rotating the shaft 41 and the synchronizing block 42 in a rotatable manner, when the rotating wheel 46 slides on the inner side of the bow frame 24, the position of the synchronizing block 42 on the shaft 41 can be changed according to the angle of pressure on the bow frame 24, and the compressed spring 44 can drive the round rod 45 to reset when the external force on the bow frame 24 disappears.

[0024] The reset assembly 5 includes two mounting parts 51, which are mounted on the top of the robot body 1. An arc-shaped rod 52 is fixedly connected to the top of the two mounting parts 51. Two curved springs 53 for resetting the synchronization block 42 are symmetrically arranged on the outside of the arc-shaped rod 52. The outside of the arc-shaped rod 52 is slidably connected to the inside of the synchronization block 42.

[0025] When the angle of the bow frame 24 changes, the synchronizing block 42 slides on the arc rod 52, compressing the curved spring 53 in the same direction. When the external force on the bow frame 24 disappears, the curved spring 53 can reset the synchronizing block 42, so that the synchronizing block 42 remains in a horizontal position.

[0026] The extension component 4 is provided with a guide component 6 on its exterior. The guide component 6 includes two guide grooves 61. The two guide grooves 61 are opened on the exterior of the round rod 45. The end of the round tube 43 is fixedly connected to two guide blocks 62 for cooperating with the guide grooves 61 to allow the round rod 45 to slide out smoothly. The exterior of the guide blocks 62 is slidably connected to the interior of the guide grooves 61.

[0027] The sliding connection between the guide block 62 and the guide groove 61 allows the wheel 46 on the round rod 45 to always maintain a horizontal sliding surface on the inner side of the bow frame 24.

[0028] The bow-shaped frame 24 is provided with a plurality of buffer components 7. Each buffer component 7 includes a telescopic component 71, which is installed on the outer side of the bow-shaped frame 24. A buffer spring 72 is sleeved on the outside of the telescopic component 71, and a sliding wheel 73 is fixedly connected to the end of the telescopic component 71.

[0029] The telescopic component 71 includes, but is not limited to, an electric push rod, a hydraulic mechanism, and a telescopic tube; In this example, the telescopic component 71 is preferably a telescopic tube. Telescopic tubes are simple in structure, low in cost, and easy to maintain.

[0030] By providing a buffer component 7 on the outside of the bow-shaped frame 24, the robot body 1 can be initially protected when it comes into contact with external objects while moving and turning.

[0031] An auxiliary component 8 is provided on the outside of the robot body 1. The auxiliary component 8 includes a spare parts storage box 81 and a soft pack 82. The spare parts storage box 81 is installed on the top of the robot body 1, and the soft pack 82 is installed on the outside of the bow-shaped frame 24.

[0032] The spare parts storage box 81 is used to store everyday signal devices for quick replacement, and the soft padding block 82 can protect the four corners of the bow frame 24.

[0033] The working principle of the practical mobile sorting robot provided by this utility model is as follows: First, when the robot body 1 moves and the sensor fails, it collides with an object. The bow-shaped frame 24 on the movable component 2 makes contact first. The movable component 2 allows the bow-shaped frame 24 to flexibly change its angle, driving the positive resistance component 3 to move backward, thereby moving the inclined plate 37. When the inclined plate 37 contacts the drive wheel 11, the continuous rotation of the drive wheel 11 pulls the inclined plate 37 below the drive wheel 11. At this time, the inclined plate 37 presses down, causing the straight rod 34 to slide down, causing the elastic element 35 to be squeezed. This allows the silicone pad 39 at the bottom of the inclined plate 37 to contact the ground, increasing the friction. As a result, the drive wheel 11 cannot drive the robot body 1 to move. Then, when the bow-shaped frame 24 is pressed, the top extension component 4 works. The synchronization block 42 connected to the rotating shaft 41 slides with the rotating wheel 46 in the bow-shaped frame 24, changing its position according to the pressure angle. When the pressure spring 44 returns to the original position, the round rod 45 is reset. Finally, the reset component 5 works in conjunction. The arc-shaped rod 52 fixed by the mounting component 51 is slidably connected to the synchronization block 42. When the external force of the bow frame 24 disappears, the curved spring 53 provides a reset force to the synchronization block 42 to keep it horizontal, completes the collision response and reset, and ensures the stable operation of the robot.

[0034] Compared with related technologies, the practical mobile sorting robot provided by this utility model has the following beneficial effects: The active wheel 11 and auxiliary wheel 12 work together to ensure smooth movement of the robot body 1, and the auxiliary wheel 12 effectively enhances balance and stability. The movable component 2 is connected to the positive resistance component 3. In the event of a collision, the positive resistance component 3 can effectively restrict the active wheel 11. The elastic element 35, the rubber strip 38 at the top of the inclined plate 37, and the silicone pad 39 at the bottom work together to increase friction, improving the robot's operational safety and stability. The extension component 4 and the reset component 5 cooperate to flexibly adjust their position and achieve reset according to the pressure on the bow frame 24, enhancing the robot's adaptability to different working conditions.
