Referring to FIG. 1, a pull AGV of the present utility model is shown with a vehicle body 10 for mobile traction, as is known in the art. The vehicle body 10 is provided with a lock mechanism 20, and the lock mechanism 20 includes a lock unit 21 and a detection unit 23. Referring to fig. 2, the locking unit 21 includes a locking driving part 211 and a locking latch 212, the locking driving part 211 is fixedly provided, and a driving end of the locking driving part 211 is connected with the locking latch 212. Preferably, the locking driving part 211 comprises an electric push rod and a signal receiver, and when receiving the driving signal, the electric push rod drives the locking bolt 212 to move so as to realize the hook butt joint with the material vehicle 40. After the traction type AGV guides the material car 40 and the material to the target position, the signal emitter can also output the unhooking signal, so that the locking driving part 211 drives the locking bolt 212 to realize automatic unhooking after receiving the unhooking signal. The detection unit 23 includes a detection rotating plate 231, a first detection sensor 232, and a return spring 233.

The detection block 2312 is thus out of the detection range of the first detection sensor 232, so that the first detection sensor 232 emits a driving signal, and the locking driving part 211 drives the locking pin 212 to move and insert into the docking hook 41 to achieve automatic hook docking after receiving the driving signal. After the material is carried, the locking bolt 212 and the butt-joint hook 41 can be automatically unlocked through the locking driving part 211.

Preferably, the detection rotating plate 231 further includes a rotating portion disposed between the abutting portion 2311 and the reset portion 2313 for setting the rotating shaft 2314. The rotating part is arranged in a V-shaped structure, so that the detection rotating plate 231 can be better matched with the butt-joint hook 41.
According to the traction type AGV, the automatic butt joint of the vehicle body 10 and the material vehicle 40 of the traction type AGV is realized by arranging the locking mechanism 20 formed by the locking unit 21 and the detecting unit 23, so that the automation degree of the traction type AGV is improved, and the efficiency of the whole conveying process is effectively ensured. The detection unit 23 prevents the locking bolt 212 from falling to lock when the butt joint hook 41 is not in place, so as to prevent the butt joint of the two. The arrangement of the return spring 233 effectively ensures the automatic return of the detection flap 231 after unhooking of the docking hook 41.
Referring to fig. 2, in some embodiments, the locking unit 21 further includes a locking connection plate 213, the locking driving part 211 is disposed at one radial side of the locking pin 212, and two ends of the locking connection plate 213 are connected to the driving end of the locking driving part 211 and the locking pin 212, respectively.

The locking connection plate 213 is arranged, so that the utilization rate of the whole structural space is high. It is conceivable that when the lock driving member 211 is coaxially disposed with the lock pin 212, a space is used in the axial direction more, resulting in a low space utilization. By the locking connection plate 213, the locking driving part 211 which is originally required to be arranged on one axial side of the locking bolt 212 is arranged on one radial side of the locking driving part, so that the space utilization rate is improved.

The cart 40 is also of different model, facing different materials. An important difference between different models of carts 40 is the difference in height, which is often the fixed in height of the existing trailing AGV interface. It is therefore difficult to achieve traction with the same trailing AGV while facing different pallet trucks 40. By arranging the lifting mechanism 30 to control the locking mechanism 20 to lift in the height direction, the same traction type AGV can realize traction on different material carts 40, and the cost of a user is reduced.

Preferably, the lifting driving component 32 is set to be a combination of a servo motor, a synchronous wheel, a synchronous belt, a screw rod and a screw rod sleeve, and the synchronous belt is driven to rotate by the servo motor to drive the synchronous wheel, so that the synchronous belt drives the screw rod to rotate and the screw rod sleeve to axially move along the screw rod. The lifting driving part 32 with the structure can effectively improve the space utilization rate compared with the structure that the screw rod is directly driven to rotate by the servo motor.
Further, referring to fig. 5, in the traction type AGV according to the present utility model, in some embodiments, the locking mechanism 20 is disposed between the lifting mounting plate 33 and the vehicle body 10, and the lifting mounting plate 33 is provided with an opening 331 corresponding to the abutment 2311. The locking mechanism 20 is arranged between the lifting mounting plate 33 and the vehicle body 10, and the opening 331 is formed, so that the locking mechanism 20 is not easily damaged by external factors, and the service life is prolonged.

when docking is performed, the height of the locking mechanism 20 is first adjusted by the lifting mechanism 30 to ensure that the locking mechanism 20 can be matched with the height of the docking hook 41 of the material cart 40. Next, the traction type AGV approaches the material carriage 40 and causes the docking hook 41 to extend into the opening 331 and abut against the detection rotating plate 231, causing the detection rotating plate 231 to rotate along the rotation shaft 2314 and causing the return spring 233 to deform; the detection block 2312 is thus out of the detection range of the first detection sensor 232, so that the first detection sensor 232 emits a driving signal, and the locking driving part 211 drives the locking pin 212 to move and insert into the docking hook 41 to achieve automatic hook docking after receiving the driving signal. At this time, the material vehicle 40 is pulled to the target place by the traction type AGV, and after the material vehicle moves to the target place, the locking driving part 211 drives the locking bolt 212 to move again to automatically unlock the docking hook 41.
