Description

Technical Field

[0001] This utility model relates to the field of handling robot technology, and more specifically, to a collision avoidance structure for a handling robot. Background Technology

[0002] A AGV (Automated Guided Vehicle) is a driverless, automated guided vehicle. Under the control of a computer system, this small vehicle automatically travels along a predetermined path to complete the handling and transportation of goods. AGVs are characterized by automation, intelligence, and high efficiency, and are widely used in modern logistics systems. A AGV consists of a base and a clamping or supporting structure, with the internal components located inside the base.

[0003] To improve the safety of the handling robot, protective rubber material is installed on all four sides of the robot's base to cushion and absorb shocks during collisions. Although this method can provide a cushioning effect, the base is prone to damage when subjected to large impacts. Utility Model Content

The tension spring is located inside the first and second connecting plates, with one end rotatably connected to the side of the first connecting plate and the other end rotatably connected to the side of the second connecting plate.

[0009] Preferably, the horizontal mechanism includes a sliding plate, a support rod, and a spring. One end of the sliding plate is rotatably connected to the side of the anti-collision plate. One end of the support rod is fixedly connected to the surface of the base of the transport robot. The other end of the support rod extends through the interior of the other end of the sliding plate.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. This utility model uses an anti-collision structure, which can play a great role in buffering and shock absorption. When the impact force is not a head-on collision, the angle of the anti-collision plate can be changed through the bending mechanism, so that the anti-collision plate can tilt accordingly, allowing the anti-collision plate to absorb the impact force and avoid rigid contact between the base of the handling robot and other objects. This improves the protection of both the base of the handling robot and other objects, and enhances the safety of the handling robot during use.

[0017] 2. This utility model uses a buffer mechanism. When an impact force hits the anti-collision plate head-on, the anti-collision plate retracts under the force, causing the horizontal mechanism to move and make the buffer rod contact other objects, thus playing a role in counter-impact. This not only achieves a buffering effect, but also prevents the impact force from being too large and affecting the stability of the handling robot, and prevents the handling robot from tilting when it is hit.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A collision avoidance structure for a transport robot includes a transport robot base 1, a transport robot transport structure 2, a collision avoidance structure 3, and a buffer mechanism 4. The transport robot transport structure 2 is installed on the top of the transport robot base 1. The collision avoidance structure 3 is located at the front and rear ends of the transport robot base 1. The collision avoidance structure 3 includes a collision avoidance plate 31, a bending mechanism 32, and a horizontal mechanism 33. The bending mechanism 32 is located between the collision avoidance plate 31 and the transport robot base 1, and the horizontal mechanism 33 is located between the upper and lower bending mechanisms 32. The buffer mechanism 4 works in conjunction with the horizontal mechanism 33.

[0031] Specifically, the bending mechanism 32 includes a connecting plate 321, a second connecting plate 322, and a tension spring 323. One end of the first connecting plate 321 is rotatably connected to the side of the anti-collision plate 31 via a pivot, and the other end of the first connecting plate 321 is rotatably connected to the second connecting plate 322 via a pivot. The end of the second connecting plate 322 away from the first connecting plate 321 is rotatably connected to the surface of the transport robot base 1 via a pivot. The tension spring 323 is located inside the first connecting plate 321 and the second connecting plate 322. One end of the tension spring 323 is rotatably connected to the side of the first connecting plate 321, and the other end of the tension spring 323 is rotatably connected to the side of the second connecting plate 322. It can reset the anti-collision plate 31 after bending, and at the same time, the tension spring 323 plays a buffering role.

[0032] Furthermore, the horizontal mechanism 33 includes a sliding plate 331, a support rod 332, and a spring 333. One end of the sliding plate 331 is rotatably connected to the side of the anti-collision plate 31. One end of the support rod 332 is fixedly connected to the surface of the transport robot base 1, and the other end of the support rod 332 extends into the interior of the other end of the sliding plate 331. The spring 333 is sleeved on the surface of the support rod 332. One end of the spring 333 is fixedly connected to the surface of the transport robot base 1, and the other end of the spring 333 is fixedly connected to the surface of the other end of the sliding plate 331. When the anti-collision plate 31 is subjected to a frontal impact, the meshing of the gear 41 and the action of the spring 333 can generate resistance during the movement of the sliding plate 331, which can greatly reduce the impact force.

[0033] It is worth noting that the buffer mechanism 4 includes a gear 41, a buffer rod 42, and a fixed rod 43. The gear 41 is located below the slide plate 331, and the buffer rod 42 is located below the gear 41. The gear 41 is rotatably connected to the surface of the transport robot base 1 via a rotating shaft. The slide plate 331 and the buffer rod 42 are provided with toothed grooves. The slide plate 331 and the buffer rod 42 are connected to the gear 41 through the toothed grooves. One end of the fixed rod 43 is fixed to the side of the transport robot base 1, and the other end of the fixed rod 43 extends into the interior of the buffer rod 42. One end of the buffer rod 42 is provided with rubber. The movement of the slide plate 331 can cause the buffer rod 42 to pass through the anti-collision plate 31 and rush towards the impact object, which can generate a reaction force to reduce the impact force generated by the impact object.

[0034] It is worth noting that the top and bottom of the anti-collision plate 31 are arc-shaped, and the connection point between the connecting plate 321 and the anti-collision plate 31 is located at the arc. When encountering a sharp impact object, the arc of the anti-collision plate 31 can change the impact direction of the impact object, so that the impact object is away from the base 1 of the handling robot.

[0035] In addition, the front of the crash barrier 31 is provided with anti-slip protective rubber to increase the friction between the impacting object and the crash barrier 31.

[0036] It must be said that the support rod 332 and the fixing rod 43 are cuboid in shape, and the buffer rod 42 and the slide plate 331 have matching grooves inside to increase the friction when the slide plate 331 and the buffer rod 42 move, and to prevent the slide plate 331 and the buffer rubber from shaking during the movement.

[0037] Working principle: When an impact occurs, the anti-collision plate 31 moves, which drives the first connecting plate 321 and the buffer rod 42 to move simultaneously. The movement of the first connecting plate 321 drives the second connecting plate 322. As the angle between the first connecting plate 321 and the second connecting plate 322 changes, the tension spring 323 is stretched, causing the tension spring 323 to deform and generate resistance. Meanwhile, the sliding plate 331 drives the gear 41 to rotate through the tooth groove, while simultaneously squeezing the spring 333 to move. The spring 333 is squeezed and deforms, generating resistance. The rotation of the gear 41 drives the bottom buffer rod 42 to move. The buffer rod 42 moves to the opposite side of the sliding plate 331's movement trajectory. As the buffer rod 42 moves, it passes the anti-collision plate 31 and contacts the impacting object, thus avoiding damage to the internal components of the handling robot base 1.
