[0002] AGVs are multi-functional vehicles capable of autonomous navigation, primarily used in processing workshops or logistics transportation. Some AGVs are too small to carry and transport goods themselves, thus requiring the use of external detachable racks for transport. These detachable racks typically have wheel hubs underneath, which are powered by the AGVs to move. Once the racks reach a preset area, they detach from the racks to begin the next trip, resulting in high transportation efficiency and preventing delays in cargo transfer due to unloading. However, existing AGV-to-external rack connection mechanisms are cumbersome and bulky, leading to larger AGVs and higher overall production costs. Utility Model Content

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] Example 1:

[0022] A connection structure for an external rack for an AGV (Automated Guided Vehicle), such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a frame assembly, fixing members 5, and connecting mechanisms 4. A set of fixing members 5 and a set of connecting mechanisms 4 are provided on both the left and right sides of the frame assembly. The fixing members 5 are located inside the frame assembly and are used to fix the connecting mechanisms 4 within the frame. The connecting mechanism 4 includes an electric push rod 42 module and a motor 43. The electric push rod 42 module includes a push rod 42 and a housing 41. The housing 41 is used to limit the push rod 42. One end of the push rod 42 is located in the housing 41, and the other end can extend from the end of the housing 41. A worm gear assembly is also provided in the housing 41. The motor 43 is located on the side of the housing 41 and drives the push rod 42 to extend from the housing 41 and perform telescopic movement through the worm gear assembly in the housing 41. The frame assembly has through holes, and the inner side of the external rack 7 has insertion holes. The push rods 42 on the left and right sides of the frame assembly extend from the through holes and are inserted into the external rack 7. Below the external rack 7... Equipped with omnidirectional wheels, the AGV can move the external rack 7 to the target point as it moves. The AGV's identification and positioning system can identify and locate the positional relationship between the vehicle body and the external rack 7 and adjust itself so that the push rod 42 can be accurately inserted into the insertion hole of the external rack 7 after it extends, thus connecting them and realizing a fully automated cargo transfer process. The frame assembly includes a top plate 3, a bottom plate 1, and side plates 2. The side plates 2 are located on the sides of the top plate 3 and the bottom plate 1, and the fasteners 5 are located between the top plate 3 and the bottom plate 1. Through holes are located on the side plates 2. The fasteners 5 are inserted into the side plates 2. The side plates 2 and the bottom plate 1 are welded together, and the side plates 2 and the top plate 3 are movably connected. The top plate 3 is mounted on the fasteners 5. At the same time, the top plate 3 and the bottom plate 1 are connected by a support column or other movable connection to facilitate the subsequent disassembly of the top plate 3 and the inspection and replacement of the electrical components inside the frame assembly.

[0023] Example 2:

[0024] This embodiment, based on the above embodiment, further defines the fixing member 5, such as... Figure 1 and Figure 2 As shown, the top surface and left side of the fastener 5 are both open structures. The bottom of the fastener 5 abuts against the base plate 1. Both the upper and lower ends of the left opening are provided with insertion parts 51. A set of limiting parts 21 is provided on the side plate 2. The insertion part 51 can be inserted into the limiting part 21 from above and connected to the side plate 2. A countersunk threaded hole 22 is provided on the side plate 2 at the position of the limiting part 21. The side plate 2 and the insertion part 51 of the fastener 5 are connected by a countersunk bolt. The countersunk bolt passes through the countersunk threaded hole 22 and is threadedly connected to the insertion part 51 of the fastener 5. To improve the stability of the fixing member 5, the middle part of the housing 41 is located in the fixing member 5. A mounting hole 52 is provided on the fixing member 5 at the position of the motor 43, and the end of the motor 43 passes through the mounting hole 52 and connects to the housing 41. A clearance groove is provided on the fixing member 5 to allow space for the end of the housing 41. Simultaneously, a rubber pad 6 is provided on the inner side wall of the fixing member 5. The rubber pad 6 can reduce the vibration generated on the electric push rod 42 module when the AGV moves, and can improve the stability of the housing 41 of the electric push rod 42 module in the fixing member 5. Other parts of this embodiment are the same as those in the above embodiment, and will not be repeated here.

[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.
