Technical Field
[0001] This utility model belongs to the field of AGV (Automated Guided Vehicle) technology, and in particular to an AGV anti-collision structure. Background Technology
[0002] AGVs are automated guided vehicles that primarily use automatic guidance devices to guide their routes. The main guidance method for AGVs is through ground wires. Wire guidance uses the magnetic field generated by the current in the ground cables to guide the vehicle along the center line based on the strength of the electromagnetic signal. AGVs are typically used in warehousing facilities to move goods using intelligent equipment, saving manpower.
[0003] Existing AGVs are equipped with multiple sensors and signal receivers on their side walls. During operation, a large number of AGVs will move back and forth within the same block. Therefore, if a system failure occurs, the AGVs may collide with each other. The sensors and signal receivers installed on the outside of the AGVs are relatively fragile and are likely to be damaged in a collision. Therefore, there is an urgent need for an AGV anti-collision structure to solve this problem. Utility Model Content

The side walls of the two sliders are symmetrically fixedly connected to two mounting plates. A connecting rod is rotatably installed between the two mounting plates. The two connecting rods rotatably installed on the side walls of the two sliders are arranged in a cross configuration. The side wall of the first buffer plate is rotatably connected to the ends of the two connecting rods, and a limit rod rotatably passes through the intersection of the two connecting rods.
[0006] Two push springs are symmetrically fixedly connected to the inner wall of the strip groove, and the ends of the two push springs are respectively fixedly connected to the side walls of the two sliders.
[0007] Springs are symmetrically fixedly connected to both sides of the main body, and a second buffer plate is fixedly connected to the ends of the two springs. The first buffer plate and the second buffer plate are fixedly connected by a rubber plate.
[0008] Preferably, a sliding rod is fixedly connected laterally inside the strip groove, and both sliders are provided with sliding holes.
[0009] Preferably, the slide rod slides through the sliding holes opened on the two sliders respectively.
[0010] Preferably, the side wall of the sliding block is fixedly connected with a limiting block, and the inner wall of the strip-shaped groove is symmetrically provided with two limiting grooves.
[0011] Preferably, the two limiting blocks fixedly connected with the side wall of the sliding block are respectively slidably connected to the interiors of the two limiting grooves provided in the inner wall of the strip-shaped groove.
[0012] Preferably, the first buffer plate and the second buffer plate are both longitudinally provided with a plurality of vertical grooves on the side away from the body, and a plurality of rollers are rotatably installed in the interiors of the vertical grooves.
[0013] Compared with the prior art, the technical effects and advantages of the AGV anti-collision structure are as follows:
[0014] The AGV anti-collision structure, thanks to the strip-shaped groove, the sliding block and the connecting rod, when the first buffer plate is subjected to a collision, the first buffer plate is pressed to be close to the side wall of the body, so as to drive the two connecting rods to rotate and drive the two sliding blocks to slide along the interior of the strip-shaped groove, and the two push springs are compressed, so as to buffer the first buffer plate.

[0027] As Figures 1 to 4 The main structure of the AGV anti-collision structure is an AGV body 1 and a first buffer plate 8 for AGV anti-collision. The side wall of the body 1 is symmetrically provided with two strip-shaped grooves 3. Two sliding blocks 4 are symmetrically and slidably connected in the strip-shaped grooves 3. Two mounting plates 5 are symmetrically and fixedly connected to the side walls of the two sliding blocks 4. A connecting rod 6 is rotatably installed between the two mounting plates 5. The two connecting rods 6 rotatably installed on the side walls of the two sliding blocks 4 are cross arranged. The side wall of the first buffer plate 8 is rotatably connected to the ends of the two connecting rods 6. The cross positions of the two connecting rods 6 are rotatably penetrated by a limiting rod. Thanks to the strip-shaped grooves 3, the sliding blocks 4 and the connecting rods 6, when the first buffer plate 8 is collided, the first buffer plate 8 is pressed to the side wall of the body 1, which drives the two connecting rods 6 to rotate and drives the two sliding blocks 4 to slide along the inside of the strip-shaped grooves 3, and compresses the two push springs 7, so as to buffer the first buffer plate 8. The inner walls of the strip-shaped grooves 3 are symmetrically and fixedly connected with two push springs 7, and the ends of the two push springs 7 are fixedly connected with the side walls of the two sliding blocks 4.
[0028] The opposite sides of the body 1 are symmetrically and fixedly connected with springs 10, the ends of the two springs 10 are fixedly connected with second buffer plates 9, the first buffer plate 8 and the second buffer plate 9 are fixedly connected through rubber plates, when the second buffer plate 9 is impacted, the spring 10 will be compressed through the second buffer plate 9 at this time and the impact force will be unloaded and buffered, thanks to the fixed connection between the first buffer plate 8 and the second buffer plate 9 through the rubber plate, the outside of the body 1 can be completely wrapped, so as to improve the anti-collision effect.
[0029] The inside of the strip-shaped groove 3 is fixedly connected with a sliding rod 12, the two sliding blocks 4 are both provided with sliding holes, the sliding rod 12 respectively slides through the sliding holes of the two sliding blocks 4, thanks to the setting of the sliding rod 12, the sliding rod 12 slides through the two sliding blocks 4, so as to limit the sliding direction of the two sliding blocks 4 and further improve the stability of the two sliding blocks 4 when sliding.
[0030] The side wall of the sliding block 4 is fixedly connected with a limiting block 11, the inner wall of the strip-shaped groove 3 is symmetrically provided with two limiting grooves, the two limiting blocks 11 fixedly connected with the side wall of the sliding block 4 are respectively slidably connected in the two limiting grooves of the inner wall of the strip-shaped groove 3, thanks to the setting of the two limiting blocks 11, the stability of the sliding block 4 when sliding can be further improved.
[0031] The side of the first buffer plate 8 and the second buffer plate 9 away from the body 1 is longitudinally provided with a plurality of vertical grooves, a plurality of vertical grooves are rotatably installed with a plurality of rollers 2, when the first buffer plate 8 and the second buffer plate 9 are not impacted in the front, the object impacted will be turned by the roller 2 at this time, so as to further reduce the impact force of the AGV trolley;
[0032] The material of the first buffer plate 8 and the second buffer plate 9 is polyethylene plastic plate, the polyethylene plastic plate (especially high-density polyethylene HDPE plate) has excellent impact strength, even in low temperature environment, it can also maintain good toughness, not easy to break or break, so it is often used to make carrying pallets, crash barriers, equipment guards and other parts that need to bear impact, the above two buffer plates can effectively improve the impact strength of the AGV.
[0033] Working principle
[0034] When the first buffer plate 8 is impacted, the two connecting rods 6 will rotate. The two connecting rods 6 are arranged in a cross configuration, which will cause the slider 4 connected to the other end of the two connecting rods 6 to slide along the inside of the strip groove 3 and compress the push spring 7 installed between the inner wall of the strip groove 3 and the side wall of the slider 4. This will buffer the first buffer plate 8 and protect the outside of the AGV. Similarly, when the second buffer plate 9 is impacted, the second buffer plate 9 will compress the spring 10 and relieve the impact force.
