[0039] like Figure 1-6 As shown, the present invention provides a back-fork AGV, including an AGV body 100, a lifting seat 200, a fork arm 300, a lifting assembly and a telescopic assembly.

[0040] The lift base 200 is mounted on top of the AGV and is slidably connected to the AGV body 100. The lift base 200 is capable of reciprocating linear motion along the Z-axis within a preset range. A fork arm 300 is mounted on the lift base 200 and is slidably connected to the lift base 200. The fork arm 300 is capable of reciprocating linear motion along the X-axis within a preset range. Specifically, in this embodiment, the fork arm 300 is U-shaped, mounted on the lift base 200, and slidably connected to the lift base 200.

[0041] The lifting assembly is mounted on top of the AGV body 100 and is in transmission connection with the lifting platform 200. It is used to drive the lifting platform 200 and position it at any desired location. The telescoping assembly is mounted on the lifting platform 200 and is in transmission connection with the fork arm 300. It is used to drive the fork arm 300.

[0042] In the working state, the lifting assembly drives the lifting base 200 to move to move the lifting base 200 to the target height, and then the telescopic assembly drives the fork arm 300 to move so that the fork arm 300 extends and moves to the bottom of the pallet. Then, the lifting assembly drives the lifting base 200 to rise to lift the pallet. Subsequently, the telescopic assembly drives the fork arm 300 to retract to move the pallet to the top of the AHG body. Finally, the lifting assembly drives the lifting base 200 to descend to place the pallet on the AGV body 100.

[0043] like Figure 1 、 5 As shown, the AGV also includes two cargo platforms 400, one on each side of the lifting base 200. The cargo platforms 400 are fixedly connected to the AGV body 100. When the lifting base 200 is in its lowest position, the bearing surface of the fork arm 300 is no higher than the bearing surface of the cargo platforms 400. In operation, the lifting assembly moves the lifting base 200 to its lowest position to place cargo on the fork arm 300 onto the cargo platforms 400, thereby reducing pressure on the lifting assembly and fork arm 300 and extending their service life.

[0044] like Figure 4 As shown, a positioning assembly is also included, which is used to position the pallet. The positioning assembly includes a positioning pin 510 and a positioning hole. One of the positioning pin 510 and the positioning hole is set on the cargo platform 400, and the other is set on the pallet.

[0045] In this embodiment, a positioning pin 510 is fixedly mounted on the top of the cargo platform 400, and a positioning hole is provided in the pallet. In operation, the positioning pin 510 is inserted into the positioning hole. The positioning pin 510 cooperates with the positioning hole to position the pallet, thereby preventing the pallet from sliding off the AGV body 100 during transportation.

[0046] Preferably, the positioning end of the positioning pin 510 is tapered to facilitate insertion into the positioning hole. In this embodiment, the positioning end of the positioning pin 510 is the top.

[0047] like Figure 4 As shown, a detection component is provided on the cargo platform 400, and the detection component is provided on the top of the AGV body 100. The detection component is electrically connected to the controller. In the working state, when the detection component detects the pallet, the controller controls the lifting component to stop running and the AGV body 100 to start.

[0048] Specifically, the detection assembly includes a detection element 610, which is fixedly mounted on the cargo platform 400. The detection element 610 can be a position sensor, a pressure sensor, or a through-beam sensor.

[0049] like Figure 1 、 5 As shown, the gantry 700 is further included. The gantry 700 is arranged on the top of the AGV body 100 . The gantry 700 is fixedly connected to the AGV body 100 , and both sides of the lifting seat 200 are slidably connected to both sides of the gantry 700 respectively.

[0051] The first transmission assembly includes a first transmission wheel 810 and a first transmission element 820. Two first transmission wheels 810 are provided, spaced longitudinally and rotatably connected to the gantry 700. The first transmission element 820 is sleeved onto the two first transmission wheels 810 and rotates with them. The first transmission element 820 is in transmission connection with the lifting base 200. In this embodiment, a vertical section of the first transmission element is fixedly connected to the lifting base 200 via a connecting element.

[0052] The lifting motor 830 is fixedly disposed on the top of the gantry 700 or the AGV body 100 , and the lifting motor 830 is drivingly connected to one of the two first transmission wheels 810 .

[0053] In the operating state, the lifting motor 830 drives the first transmission wheel 810 to rotate forward, thereby driving the first transmission element 820 to rotate forward, thereby achieving the purpose of driving the lifting platform 200 to rise. The lifting motor 830 drives the first transmission wheel 810 to rotate reversely, thereby driving the first transmission element 820 to rotate reversely, thereby achieving the purpose of driving the lifting platform 200 to descend.

[0054] In this embodiment, two first transmission assemblies are provided, and the two first transmission assemblies are respectively provided on both sides of the gantry 700 to improve the stability and reliability of the driving of the lifting seat 200 .

[0055] Specifically, the first transmission wheel 810 can be a pulley, a sprocket, etc., and the first transmission element 820 can be a transmission belt adapted to the pulley, or a transmission chain adapted to the sprocket. In this embodiment, the first transmission wheel 810 is a pulley, and the first transmission element 820 is a transmission belt.

[0056] like Figure 6 As shown, the telescopic assembly includes a second transmission wheel 910 , a second transmission element 920 and a telescopic motor 930 .

[0057] Two second transmission wheels 910 are provided, spaced apart along the length of the lifting platform 200 and rotatably connected to the lifting platform 200. A second transmission element 920 is mounted on the two second transmission wheels 910 and rotates with the rotation of the second transmission wheels 910. The second transmission element 920 is in transmission connection with the fork arm 300. In this embodiment, a horizontal section of the second transmission element 920 is fixedly connected to the fork arm 300 via a connecting element. A telescopic motor 930 is fixedly mounted on the lifting platform 200, and the lifting motor 830 is in transmission connection with one of the two second transmission wheels 910.

[0058] In the working state, the telescopic motor 930 drives the second transmission wheel 910 to rotate forward, thereby driving the second transmission element 920 to rotate forward, thereby achieving the purpose of driving the fork arm 300 to extend, and the telescopic motor 930 drives the second transmission wheel 910 to rotate reversely, thereby driving the second transmission element 920 to rotate reversely, thereby achieving the purpose of driving the fork arm 300 to retract.

[0059] Specifically, the second transmission wheel 910 can be a pulley, a sprocket, etc., and the second transmission element 920 can be a transmission belt adapted to the pulley, a transmission chain adapted to the sprocket. In the present embodiment, the second transmission wheel 910 is a pulley, and the second transmission element 920 is a transmission belt.
