Description

Technical Field

[0001] This invention relates to the field of warehouse management technology, specifically to an AGV logistics vehicle that facilitates unloading. Background Technology

[0002] With the rapid development of the logistics industry, the application of automated logistics systems in warehousing and transportation is gradually increasing. In particular, AGVs (Automated Guided Vehicles), as a highly efficient automated transportation tool, have been widely used in warehousing, production lines, and material handling scenarios. These AGVs are typically used for material handling and unloading, and the requirements for stability, accuracy, and efficiency during transportation are becoming increasingly stringent.

[0003] Currently, most AGV logistics vehicles rely on manual operation or fixed unloading platforms for material delivery. During unloading, a traditional tilting method is typically used, with materials unloaded via a tilting platform or tipping device. This method requires manual intervention or manual control to adjust the tilt angle and delivery position of the unloading platform, which not only increases the complexity of manual operation but also affects unloading speed in some cases, especially in situations requiring efficient and rapid material delivery. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an AGV logistics vehicle that facilitates unloading. It solves the problem that traditional unloading methods require manual or semi-automatic control to adjust the tilt angle and material placement position, which cannot complete unloading quickly and efficiently. Especially in scenarios requiring frequent unloading, over-reliance on manual adjustments not only affects unloading efficiency but may also increase the burden on operators, leading to a decrease in the overall system efficiency.

A connecting limiting plate is rotatably connected to the inner wall of the adjusting column, and a limiting guide rail is slidably provided on the inner wall of the connecting limiting plate. The upper surface of the limiting guide rail is fixedly connected to the lower surface of the lifting plate.

[0008] Preferably, a drive plate is fixedly connected to the outer wall of the third drive rod, a drive motor is fixedly connected to the inner wall of the drive plate, a pawl is fixedly connected to the output end of the drive motor, and the other side of the pawl is rotatably connected to the outer wall of the middle left side of the drive plate.

[0009] Preferably, the pawl is connected to a ratchet with its teeth engaged, the inner wall of the ratchet is fixedly connected to the outer wall of the third drive rod, two sets of ratchet and pawl are provided and the teeth of the ratchet are arranged oppositely, and a gear is fixedly connected to the upper outer wall of the drive plate.

[0010] Preferably, the gear teeth are meshed with a toothed plate, the outer wall of the toothed plate is slidably connected to the inner wall of the lifting plate, a limit sleeve is slidably provided on the outer wall of the toothed plate, the outer wall of the limit sleeve is fixedly connected to the inner wall of the lifting plate, and an extension plate is fixedly connected to the outer wall of the toothed plate.

[0011] Preferably, the anti-deviation component includes a first adjusting block, the upper surface of which is slidably connected to the lower surface of the lifting plate, the outer wall of which is fixedly connected to the outer wall of the connecting limiting plate, and a second electric push rod is rotatably provided on the outer wall of the first adjusting block.

[0012] Preferably, the output end of the second electric push rod is fixedly connected to a second adjusting block, the inner wall of the second adjusting block is rotatably connected to a first adjusting plate, the outer wall of the first adjusting plate is rotatably connected to a limit block, and the outer wall of the limit block is slidably connected to the outer wall of the limit guide rail.

[0013] Preferably, a second adjusting plate is rotatably connected to one side of the outer wall of the first adjusting plate, a clamping rod is fixedly connected to the inner wall of the second adjusting plate, a clamping shell is rotatably connected to the outer wall of the clamping rod, the inner wall of the clamping shell is slidably connected to the outer wall of the limiting guide rail, and the outer wall of the clamping rod is slidably connected to the inside of the extension plate.

[0014] Preferably, a vehicle body is fixedly mounted on the outer wall of the base, and a laser radar is installed at each of the four corners of the vehicle body. A baffle is fixedly connected to both sides of the vehicle body, and a wheel is installed on the inner side of the baffle.

[0015] Working principle: When this AGV is needed, it is deployed in conjunction with existing warehousing systems or other control systems. When the AGV is detected to have arrived at the designated position, the motor drives the first drive rod, which in turn drives the first adjusting rod, which in turn drives the second adjusting rod, driving the tilting table to achieve the tilting and dumping of materials. During use, when heavy or large materials need to be dumped to a specific location, the tilting table ensures more stable material delivery and avoids material deviation or mis-delivery. The first electric push rod drives the locking block to slide, pushing the tilting rod to adjust the height and tilt angle of the tilting table to meet the needs of different unloading heights and delivery directions, improving work efficiency and reducing manual operation during on-site material unloading.

[0016] A dual-head motor drives the third drive rod, which in turn drives the second drive rod and the adjusting column, causing the connecting limit plate to slide. This ensures the stability of the connecting limit plate and prevents excessive shaking. During material handling in warehouses or production lines, the sliding function of the connecting limit plate ensures secondary fixation of the material. For materials that are prone to tilting or are irregular, this prevents them from tilting or collapsing during transportation. The drive plate drives the pawl to rotate, and the pawl meshes with the ratchet, driving the gear to rotate. This drives the toothed plate to slide, causing the extension plate to unfold, increasing the contact area of ​​the material and improving transportation stability. During transportation, the unfolding of the extension plate can be adapted to the size of the material to ensure stability during transportation and prevent the material from sliding or tilting.

[0017] The second electric push rod drives the second adjusting block and the first adjusting plate, which in turn drives the clamping rod to rotate. The clamping rod holds the material, preventing it from falling off or tilting during transport. In production workshops or logistics warehouses, the clamping rod ensures that irregularly shaped or small materials will not fall off during transport due to vibration or high-speed movement. By extending and retracting the clamping rod, combined with the positioning system, the trolley is positioned, ensuring the material is centered and increasing the stability of the transport process. This prevents damage caused by material deviation during transport, especially in complex storage environments or narrow transport channels. Therefore, during use, it not only achieves the goal of controlling the material's movement through electric... The machine body drives the first drive rod, the first adjusting rod, and the second adjusting rod to drive the tilting table to tilt, enabling materials to be placed in different directions and heights. This improves unloading speed and reduces manual intervention during use. It also features a dual-head motor driving the third and second drive rods, which in turn drive the adjusting column and connecting limit plate. Combined with the clamping assembly, this prevents materials from tilting or collapsing, thus maintaining material stability and preventing displacement and tilting during transportation. Furthermore, the expansion and contraction of the clamping rods, combined with the second electric push rod and positioning system, ensures precise positioning of materials during transportation, preventing material from falling off and improving the stability of the transportation process.

[0018] This invention provides an AGV (Automated Guided Vehicle) logistics cart that facilitates unloading. It has the following beneficial effects:

[0019] 1. This invention uses a motor to drive a first drive rod, a first adjusting rod, and a second adjusting rod to drive the tilting table to tilt, enabling materials to be placed in different directions and at different heights. This improves unloading speed and reduces manual intervention during use.

[0020] 2. This invention uses a dual-head motor to drive the third and second drive rods, which in turn drive the adjusting column and connecting limit plate. Combined with the clamping assembly, it prevents the material from tilting or collapsing, thus achieving the effect of keeping the material stable and preventing material displacement and tilting during transportation.

[0021] 3. This invention, through the expansion and contraction of the clamping rod, combined with the second electric push rod and positioning system, ensures accurate positioning of materials during transportation, prevents materials from falling off, and achieves the effects of improving the stability of the transportation process and preventing materials from falling off.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides an AGV logistics trolley for easy unloading, including a base 1. A motor body 2 is fixedly connected to the upper surface of the base 1. A first drive rod 3 is fixedly connected to the output end of the motor body 2. The outer wall of the first drive rod 3 is rotatably connected to the inner wall of the base 1. A first adjusting rod 4 is fixedly connected to the outer wall of the first drive rod 3. A second adjusting rod 5 is rotatably connected to the outer wall of the first adjusting rod 4. A flipping platform 9 is rotatably connected to the outer side of one end of the second adjusting rod 5. A support platform 6 is slidably connected to the outer wall of the flipping platform 9. A flipping rod 12 is fixedly connected to the outer wall of the flipping rod 12. A telescopic column 13 is rotatably connected to the outer wall of the telescopic column 13. A first electric push rod 10 is fixedly connected to the outer wall of the first electric push rod 10. A locking block 11 is fixedly connected to the output end of the first electric push rod 10. The outer wall of the locking block 11 is slidably connected to the inside of the telescopic column 13. The lower surface of the locking block 11 is slidably disposed on the upper side of the flipping rod 12. An extension component is provided on the inner wall of the flipping platform 9. An anti-deviation component is provided on the lower side of the extension component.

[0033] Specifically, conventional logistics trolleys, including those commonly used in electronics factories and warehouse management vehicles, can only place materials in place during unloading. However, they cannot function when materials need to be dropped or tilted. This device, however, uses a motor body 2 to drive a first drive rod 3 and a first adjusting rod 4, which in turn drive a second adjusting rod 5 to move a tilting table 9. This, along with the tilting rod 12 and the first electric push rod 10, allows for height adjustment when all four first electric push rods 10 simultaneously engage the locking blocks 11 to engage the tilting rods 12 in both directions. This allows for upward material receiving or lifting during use. When the two first electric push rods 10 and the locking block 11 on one side of the single control are driven, they slide out through the inner wall of the telescopic column 13 via the flipping rod 12 on the other side. Thus, during use, the second adjusting rod 5, when working upward, achieves the effect of flipping the flipping table 9, the extension plate 8, and the lifting plate 7. Moreover, the unloading direction can be controlled by opening and closing the first electric push rod 10 on the opposite side, allowing the other side to flip. Thus, the unloading effect can be completed without the trolley turning around during use. This reduces the trolley turning around repeatedly during use, thereby reducing the repeated detection and heat generation of the sensors, saving more power during the unloading process, and further increasing the unloading speed of the trolley during use.

[0034] Please see the appendix Figure 5 The extension assembly includes a lifting plate 7, the lower surface of which is fixedly connected to the upper surface of the tilting table 9. A dual-head motor 14 is fixedly connected to the lower surface of the lifting plate 7, and a third drive rod 19 is fixedly connected to the output end of the dual-head motor 14. A second drive rod 15 is fixedly connected to the outer wall of the third drive rod 19. Adjusting columns 16 are rotatably connected to both sides of the second drive rod 15. A connecting limit plate 17 is rotatably connected to the inner wall of the adjusting column 16. A limit guide rail 18 is slidably provided on the inner wall of the connecting limit plate 17, and the upper surface of the limit guide rail 18 is fixedly connected to the lower surface of the lifting plate 7.

[0035] Specifically, when the second drive rod 15 and the adjusting column 16 are driven to rotate by the dual-head motor 14, the connecting limiting plate 17 is driven to slide under the limit of the limiting guide rail 18 by the adjusting column 16. This can drive the clamping assembly to move outward, so that the material can be fixed again according to the size of the material during use, preventing tilting and collapse. The connecting limiting plate 17 can further ensure the stability of the connecting limiting plate 17 during the movement, preventing large shaking and ensuring the stability of the movement.

[0036] Please see the appendix Figure 5 - Appendix Figure 7A drive plate 20 is fixedly connected to the outer wall of the third drive rod 19. A drive motor 22 is fixedly connected to the inner wall of the drive plate 20. A pawl 21 is fixedly connected to the output end of the drive motor 22. The other side of the pawl 21 is rotatably connected to the outer wall of the middle left side of the drive plate 20. A ratchet 23 is meshed with the tooth end of the pawl 21. The inner wall of the ratchet 23 is fixedly connected to the outer wall of the third drive rod 19. Two sets of ratchet 23 and pawl 21 are provided, and the tooth ends of the ratchet 23 are arranged oppositely. A gear 24 is fixedly connected to the upper outer wall of the drive plate 20. A toothed plate 25 is meshed with the tooth end of the gear 24. The outer wall of the toothed plate 25 is slidably connected to the inner wall of the lifting plate 7. A limit sleeve 26 is slidably provided on the outer wall of the toothed plate 25. The outer wall of the limit sleeve 26 is fixedly connected to the inner wall of the lifting plate 7. An extension plate 8 is fixedly connected to the outer wall of the toothed plate 25.

[0037] Specifically, when the third drive rod 19 is driven by the dual-head motor 14, the ratchet 23 rotates. During use, when the transported products are too large or too numerous, the pawl 21 rotates around the third drive rod 19 via the drive plate 20. The pawl 21 rotates via the drive motor 22 and engages with the ratchet 23, thereby driving the drive plate 20 to rotate. This drives the lower gear 24 to drive the toothed plate 25 to slide the extension plate 8 on the inner wall of the lifting plate 7 under the limit of the limiting sleeve 26. During use, the lifting plate 7 can expand to both sides, thereby adjusting the contact area with the material above. This not only increases the contact area and improves the stability during transport, but also allows it to adapt to the transport of various materials.

[0038] Please see the appendix Figure 1 and attached Figure 8 The anti-deviation component includes a first adjusting block 27, the upper surface of which is slidably connected to the lower surface of the lifting plate 7. The outer wall of the first adjusting block 27 is fixedly connected to the outer wall of the connecting limiting plate 17. A second electric push rod 28 is rotatably mounted on the outer wall of the first adjusting block 27. A second adjusting block 29 is fixedly connected to the output end of the second electric push rod 28. A first adjusting plate 30 is rotatably connected to the inner wall of the second adjusting block 29. A limiting block 31 is rotatably connected to the outer wall of the first adjusting plate 30. The outer wall of the limiting block 31 is slidably connected to the outer wall of the limiting guide rail 18. A second adjusting plate 32 is rotatably connected to one side of the outer wall of the first adjusting plate 30. A clamping rod 34 is fixedly connected to the inner wall of the second adjusting plate 32. A clamping shell 33 is rotatably connected to the outer wall of the clamping rod 34. The inner wall of the clamping shell 33 is slidably connected to the outer wall of the limiting guide rail 18. The outer wall of the clamping rod 34 is slidably connected to the interior of the extension plate 8.

[0039] Specifically, during use, the second electric push rod 28 pushes the second adjusting block 29 and the first adjusting plate 30 under the limit of the first adjusting block 27. When the first adjusting plate 30 is pushed, the first adjusting plate 30 drives the second adjusting plate 32 to rotate under the limit of the limiting block 31. Thus, during use, the clamping rod 34 can clamp the transported material on both sides. During use, the clamping rods 34 on both sides can protect smaller or irregularly shaped materials. During use, it can prevent the material from falling off when the trolley is moving. During the feeding process, it also has the effect of preventing the material from falling off the feeding port. During use, it further increases the effect of preventing the material from falling off during the feeding process. The extension plate 8 has a limit groove in the movement trajectory of the clamping rods 34 on both sides, which can further increase the stability of the clamping rods 34 during use.

[0040] In conventional logistics carts, positioning is achieved using positioning radar or laser sensors when transporting larger materials. When the clamping rod 34 is extended outward, it also serves a positioning function. After the clamping rod 34 is extended, the second electric push rod 28 drives the first adjusting plate 30 and the limiting block 31 to move. Simultaneously, the dual-head motor 14 drives the third drive rod 19 and the second drive rod 15 to retract, thereby achieving the positioning and centering effect of the cart body. During use, the center point of the material can be obtained, resulting in better stability during transportation and preventing the material from tilting and collapsing due to uneven force during transportation.

[0041] Please see the appendix Figure 1 A vehicle body 35 is fixedly installed on the outer wall of the base 1. LiDAR is installed at each of the four corners of the vehicle body 35. Baffles 36 are fixedly connected to both sides of the vehicle body 35. Wheels 37 are installed on the inner side of the baffles 36.

[0042] Specifically, lidar can acquire information about the vehicle's surroundings during use to prevent collisions, while barriers and wheels are used for vehicle movement.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
