They integrate multiple technologies such as hydraulic lifting, PLC control, and wireless scheduling, and are programmable with autonomous navigation capabilities.
[0003] AGV forklifts have been widely used in logistics, warehousing, industrial manufacturing and other fields. However, during the cargo transfer process, existing AGV forklifts are prone to collisions with shelves or other forklifts, which can cause damage to the forklifts or goods to fall, affecting operational efficiency and safety.
[0004] Therefore, it is necessary to propose an AGV forklift anti-collision device to solve the above problems. Utility Model Content

[0006] Technical solution: To achieve the above objectives, this utility model is implemented through the following technical solution: an AGV forklift anti-collision device, including a buffer device installed on the AGV forklift, the buffer device including buffer component I, buffer component II and limiting component;
[0007] The AGV forklift includes a forklift body and a fork carriage. The fork carriage has an installation cavity Ⅲ at its end. The buffer assembly Ⅰ includes a slide plate Ⅱ that is slidably installed in the installation cavity Ⅲ. A spring Ⅱ and a pressure sensor Ⅱ are provided on the side of the slide plate Ⅱ near the forklift body. A connecting plate is fixedly installed on the other side of the slide plate Ⅱ. The other end of the connecting plate passes through the installation cavity Ⅲ and a buffer block is fixedly installed thereon.
[0008] The buffer assembly II includes a buffer plate disposed on the side of the forklift body away from the fork carriage, a spring shock absorber fixedly installed between the buffer plate and the forklift body, and a fixing block fixedly installed on both sides of the forklift body. The fixing block has an installation cavity I in the middle. Connecting rods are fixedly installed at both ends of the buffer plate. One end of each connecting rod is inserted into the installation cavity I on the adjacent side and a locking block is fixedly installed. A pressure sensor I is provided at the end of the installation cavity I away from the buffer plate.
[0009] The fork carriage has multiple mounting slots spaced along its length on its bearing surface. The limiting component includes a rotating shaft rotatably mounted on the end of the mounting slot away from the forklift body, and a limiting plate is fixedly mounted on the rotating shaft. A permanent magnet is fixedly mounted on the bottom of the limiting plate at the end away from the rotating shaft, and an electromagnet is fixedly mounted on the bottom of the mounting slot directly below the permanent magnet. Arc-shaped slots concentric with the rotating shaft are opened on both the left and right side walls of the mounting slot. A sliding rod is slidably mounted in the arc-shaped slot and is fixedly connected to the limiting plate.
[0010] The pressure sensor I, pressure sensor II, and electromagnet are all connected to the control system of the AGV forklift. When pressure sensor I or pressure sensor II is triggered, the control system controls the electromagnet to be energized. After being energized, the electromagnet has the same magnetic pole as the opposite side of the permanent magnet, so as to drive the limit plate to tilt up around the rotation axis.
[0011] Preferably, the buffer block is wrapped with a rubber layer, and a through hole is provided on the side wall of the mounting cavity III away from the forklift body. One end of the connecting plate extends out of the mounting cavity III through the through hole. The pressure sensor II is fixedly installed on the side wall of the mounting cavity III near the forklift body. The spring II is sleeved on the outside of the pressure sensor II, and the two ends of the spring II are fixedly connected to the slide plate II and the fork carriage, respectively.
[0012] Preferably, the depth of the mounting groove is a, the thickness of the limiting plate is b, where a≥b, and mounting holes are provided at the bottom of both the limiting plate and the mounting groove. The two mounting holes are concentrically arranged, and the permanent magnet and the electromagnet are respectively installed in the corresponding mounting holes.
[0013] Preferably, a mounting cavity II is provided below the side of the mounting cavity I away from the forklift body. A sliding plate I is vertically slidably installed in the mounting cavity II.

The upper and lower ends of the spring I are fixedly connected to the sliding plate I and the fixing block, respectively. A through groove is provided on the inner top surface of the mounting cavity II, which is in communication with the mounting cavity I. A trapezoidal block is provided in the through groove, and the lower end of the trapezoidal block is fixedly connected to the sliding plate I.
[0014] Beneficial Effects: Compared with the prior art, this utility model provides an AGV forklift anti-collision device. This AGV forklift anti-collision device has a unique structure and is easy to use. When the buffer block at the front of the fork is impacted during the transfer process of the AGV forklift, spring II provides buffering and shock absorption. The sliding plate squeezes pressure sensor II, and pressure sensor II transmits a signal to the control system, which controls the electromagnet to act, causing the end of the limit plate near the forklift body to tilt up under the action of magnetic force, preventing the goods from falling. When the AGV forklift is rear-ended, the buffer plate is impacted. The spring shock absorber between the buffer plate and the forklift body can reduce vibration and avoid damage to internal components. The buffer plate moves towards the forklift body, and the push block squeezes pressure sensor I. Pressure sensor I transmits a signal to the control system, which controls the electromagnet to act, also causing the limit plate to tilt up, preventing the goods from falling.
[0015] Through the coordinated operation of the buffer component and the limiting component, on the one hand, the buffer component can effectively absorb and buffer the impact force, reduce the impact on the forklift and goods, and reduce the risk of equipment damage and goods loss. On the other hand, after the pressure sensor detects the impact signal, it automatically triggers the control system to realize the action of the electromagnet, causing the limiting plate to tilt up, which can effectively prevent the goods from falling under the impact, avoid secondary accidents, and protect the safety of personnel and equipment.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example 1: This example 1 provides an AGV forklift anti-collision device, which is a direct improvement on an existing AGV forklift. It has a unique structure. Please refer to [link / reference]. Figure 1-4 As shown, a buffer device is installed on the AGV forklift 1. The buffer device includes a buffer assembly I, a buffer assembly II, and a limiting assembly. The AGV forklift 1 includes a forklift body and a fork carriage. The end of the fork carriage is provided with a mounting cavity III12. The buffer assembly I includes a sliding plate II13 that is slidably installed in the mounting cavity III12. A spring II14 and a pressure sensor II15 are provided on the side of the sliding plate II13 near the forklift body. A connecting plate 16 is fixedly installed on the other side of the sliding plate II13. The other end of the connecting plate 16 passes through the mounting cavity III12 and a buffer block 17 is fixedly installed thereon.
[0023] The buffer block 17 is wrapped with a rubber layer. A through hole is provided on the side wall of the mounting cavity Ⅲ12 away from the forklift body. One end of the connecting plate 16 extends out of the mounting cavity Ⅲ12 through the through hole. The pressure sensor Ⅱ15 is fixedly installed on the side wall of the mounting cavity Ⅲ12 near the forklift body. The spring Ⅱ14 is sleeved on the outside of the pressure sensor Ⅱ15, and the two ends of the spring Ⅱ14 are fixedly connected to the slide plate Ⅱ13 and the fork carriage, respectively.
[0024] The buffer assembly II includes a buffer plate 2 disposed on the side of the forklift body away from the fork carriage, a spring shock absorber 25 fixedly installed between the buffer plate 2 and the forklift body, and a fixing block 3 fixedly installed on both sides of the forklift body. The fixing block 3 has an installation cavity I10 in the middle. Connecting rods 4 are fixedly installed at both ends of the buffer plate 2. One end of each connecting rod 4 is inserted into the installation cavity I10 on the adjacent side and a locking block 5 is fixedly installed. A pressure sensor I9 is provided at the end of the installation cavity I10 away from the buffer plate 2. A through hole communicating with the installation cavity I10 is provided at the end of the fixing block 3 near the buffer plate 2. The two connecting rods 4 are inserted into the installation cavity I10 through the through hole.
[0025] Multiple mounting slots 18 are spaced apart along the length of the forklift's bearing surface. The limiting component includes a rotating shaft 19 rotatably mounted on the end of the mounting slot 18 away from the forklift body. A limiting plate 20 is fixedly mounted on the rotating shaft 19. A permanent magnet 23 is fixedly mounted on the bottom of the end of the limiting plate 20 away from the rotating shaft 19. An electromagnet 24 is fixedly mounted on the bottom of the mounting slot 18 directly below the permanent magnet 23. Arc-shaped slots 21 are provided on both the left and right side walls of the mounting slot 18, concentric with the rotating shaft 19. A sliding rod 22 is slidably mounted in the arc-shaped slot 21. The sliding rod 22 is fixedly connected to the limiting plate 20. Pressure sensor I 9, pressure sensor II 15, and electromagnet 24 are all connected to the control system of the AGV forklift 1.
[0026] There are multiple ways to install the permanent magnet 23 and the electromagnet 24. For example, the depth of the mounting groove 18 is a, the thickness of the limiting plate 20 is b, where a≥b, and the bottom of both the limiting plate 20 and the mounting groove 18 are provided with mounting holes. The two mounting holes are concentrically set, and the permanent magnet 23 and the electromagnet 24 are respectively installed in the corresponding mounting holes. When the electromagnet 24 is energized, the magnetic poles of the electromagnet 24 and the permanent magnet 23 are the same.
[0027] Working principle: When the AGV forklift 1 is rear-ended during transport, the buffer plate 2 is impacted. The spring shock absorber 25 can significantly reduce the vibration experienced by the AGV forklift 1, thereby preventing damage to the internal components of the AGV forklift 1. At the same time, the buffer plate 2 moves towards the AGV forklift 1 and pushes the locking block 5 to compress the pressure sensor I9. The pressure sensor I9 transmits a signal to the control system of the AGV forklift 1. The control system of the AGV forklift 1 controls the electromagnet 24 to move. Since the electromagnet 24 is energized, the electromagnet 24 and the permanent magnet 23 face each other. Since the magnetic poles are the same, the end of the limit plate 20 near the forklift body will tilt up under the action of magnetic force, thereby preventing the goods on the forklift from falling off upon impact. When the buffer block 17 is impacted, the spring II 14 provides cushioning and shock absorption. At the same time, the slide plate II 13 squeezes the pressure sensor II 15, and the pressure sensor II 15 transmits the signal to the control system of the AGV forklift 1. The control system of the AGV forklift 1 controls the electromagnet 24 to move, which also causes the end of the limit plate 20 near the forklift body to tilt up under the action of magnetic force, preventing the goods on the forklift from falling off upon impact.
[0028] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 2 As shown, mounting cavity I10 has a mounting cavity II11 located on the side away from the forklift body. A sliding plate I6 is vertically slidably mounted inside mounting cavity II11. Pressure sensor I9 is fixedly mounted on the inner bottom surface of mounting cavity II11. A spring I8 is provided on one side of pressure sensor I9. The upper and lower ends of spring I8 are fixedly connected to sliding plate I6 and fixing block 3, respectively. A through groove is provided on the inner top surface of mounting cavity II11, which is in communication with mounting cavity I10. A trapezoidal block 7 is provided in the through groove. The lower end of trapezoidal block 7 is fixedly connected to sliding plate I6. By placing pressure sensor I9 inside mounting cavity II11, direct impact of the locking block 5 on pressure sensor I9 can be avoided, thus extending the service life of pressure sensor I9.
