For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Combination Figure 1 and Figure 2 As shown, this application embodiment provides an unmanned transport vehicle body 100, including a vehicle head 10 and a movable body 20. A functional module 30 is provided on the vehicle head 10. The functional module 30 is connected to the movable body 20 through a first cable. The vehicle head 10 can rotate relative to the movable body 20 to switch between a first position and a second position. When the vehicle head 10 is in the first position, the functional module 30 is in a normal working position. When the vehicle head 10 is in the second position, its height dimension is smaller than its height dimension when it is in the first position.

[0024] When packaging the Automated Guided Vehicle (AGV) body 100, it is not necessary to disassemble the vehicle head 10 from the movable body 20, nor is it necessary to disconnect the first cable connecting the functional module 30 and the movable body 20. Simply rotate the vehicle head 10 relative to the movable body 20 to a second position, reducing the height of the vehicle head 10 to facilitate packaging. Upon receiving the product, the customer does not need to reinstall the vehicle head 10 onto the movable body 20, nor does it need to rewire the functional module 30 and the movable body 20. Simply rotate the vehicle head 10 from the second position to the first position, placing the functional module 30 in its normal operating position, and the AGV body 100 is ready for normal use, thus improving installation convenience.

[0025] Figure 1 The front of the vehicle 10 shown is in the first position. When the front of the vehicle 10 is in the first position, it can be in a vertical state. The front of the vehicle 10 in the vertical state has high stability, is not easy to tilt to the sides, and is more aesthetically pleasing. Figure 2 The front of the vehicle 10 shown is in the second position. When the front of the vehicle 10 is in the second position, it can be laid flat horizontally. The front of the vehicle 10 in the horizontally laid-flat state has the smallest dimension in the height direction, which makes it easier to package the unmanned transport vehicle body 100.

[0026] It should be noted that the movable vehicle body 20 in this embodiment has the characteristic of being able to move independently. Similar to the body of a typical unmanned transport vehicle, the movable vehicle body 20 also includes a shell, a drive unit, and wheels. The wheels are rotatably mounted on the bottom of the shell, and the drive unit is located on the shell and connected to the wheels, enabling it to drive the wheels to rotate, thereby controlling the movement of the movable vehicle body 20. The normal operating position of the functional module 30 refers to the position of the functional module 30 when the unmanned transport vehicle is in normal use. The functional module 30 may include a navigation module, which can provide navigation signals to the movable vehicle body 20, guiding its movement direction and ensuring that the unmanned transport vehicle body 100 accurately travels to the target position. The front of the vehicle 10 can increase the installation height of the navigation module, thereby increasing the detection range of the navigation module. In this embodiment, the navigation module includes a lidar 31 and an obstacle avoidance camera 32. In other embodiments, the functional module 30 may also include a light-emitting module, a sound-emitting module, a display module, etc.

[0027] In some embodiments, combined with Figure 3 and Figure 4 As shown, the movable vehicle body 20 is provided with an arc-shaped slide rail 211. The front of the vehicle 10 is connected to a sliding member 40, which is slidably connected to the arc-shaped slide rail 211. When the sliding member 40 is located at one end of the arc-shaped slide rail 211, the front of the vehicle 10 is in a first position; when the sliding member 40 is located at the other end of the arc-shaped slide rail 211, the front of the vehicle 10 is in a second position. The two ends of the arc-shaped slide rail 211 limit the sliding member 40, thereby restricting the rotation angle of the front of the vehicle 10 and ensuring that the front of the vehicle 10 can only rotate between the first and second positions, preventing the front of the vehicle 10 from rotating excessively and colliding with the movable vehicle body 20. The arc-shaped slide rail 211 shown in the figure is specifically an arc-shaped groove, which is formed by the groove bottom and the groove sidewall. In some other embodiments, the arc-shaped groove can also be an arc-shaped through hole. In other embodiments, the positions of the arc-shaped slide 211 and the sliding member 40 can be interchanged. That is, the arc-shaped slide 211 is located at the front of the vehicle 10, and the sliding member 40 is connected to the movable vehicle body 20. In this case, the sliding member 40 is a stationary component, and the arc-shaped slide 211 is a moving component.

[0028] In some embodiments, such as Figure 3As shown, the movable vehicle body 20 has two connecting parts 21 arranged at relative intervals. The front of the vehicle 10 extends between the two connecting parts 21. The two connecting parts 21 are rotatably connected to the opposite sides of the front of the vehicle 10. At least one connecting part 21 is provided with a first through hole 212 and an arc-shaped slide 211. The arc-shaped slide 211 is an arc-shaped groove provided on the side of the connecting part 21 facing the front of the vehicle 10. The first through hole 212 is provided on the side of the connecting part 21 facing away from the front of the vehicle 10. The first through hole 212 extends to the bottom of the arc-shaped groove to communicate with the arc-shaped groove. The sliding member 40 is detachably connected to the front of the vehicle 10. When the sliding member 40 is aligned with the first through hole 212, the sliding member 40 can be detached from the first through hole 212. By forming two spaced-apart connecting portions 21 on the movable body 20, and extending the front of the vehicle 10 between the two connecting portions 21, the two connecting portions 21 are rotatably connected to the opposite sides of the front of the vehicle 10, which improves the connection reliability between the front of the vehicle 10 and the movable body 20, as well as the stability of the front of the vehicle 10 when rotating. The arc-shaped slide 211 is an arc-shaped groove provided on the side of the connecting portion 21 facing the front of the vehicle 10. Compared with an arc-shaped through hole, the arc-shaped groove design can prevent the sliding member 40 from accidentally coming out, ensuring the connection reliability between the sliding member 40 and the arc-shaped slide 211. In order to meet the installation and removal of the sliding member 40, a first through hole 212 communicating with the arc-shaped groove is opened on the side of the connecting portion 21 facing away from the front of the vehicle 10. Thus, when the sliding member 40 is aligned with the first through hole 212, the sliding member 40 can be removed from the first through hole 212, and of course, it can also be inserted through the first through hole 212 to extend into the arc-shaped groove and connect with the front of the vehicle 10. Specifically, when the vehicle head 10 is in the first position, the sliding member 40 is aligned with the first through hole 212. When the vehicle head 10 is in the second position, the sliding member 40 is offset from the first through hole 212, thereby preventing the sliding member 40 from coming off the first through hole 212 when transporting the packaged unmanned transport vehicle body 100. Only one connecting part 21 may have the first through hole 212 and the arc-shaped slide rail 211, or both connecting parts 21 may have the first through hole 212 and the arc-shaped groove. When only one connecting part 21 has the first through hole 212 and the arc-shaped groove, the vehicle head 10 is connected to the sliding member 40 on only one side. When both connecting parts 21 have the first through hole 212 and the arc-shaped groove, the opposite sides of the vehicle head 10 are connected to the sliding member 40, and the two sliding members 40 are slidably connected to the two arc-shaped grooves respectively.

[0029] In some embodiments, such as Figure 5As shown, the front of the vehicle 10 is provided with a first threaded hole (not shown), and the sliding member 40 is a first threaded fastener. The first threaded fastener includes a head 41 and a threaded shank 42 that are fixedly connected. The head 41 is located in an arc-shaped groove, and the threaded shank 42 is threadedly connected to the first threaded hole. The diameter of the first through hole 212 is greater than or equal to the diameter of the head 41. When the front of the vehicle 10 rotates relative to the movable body 20, the head 41 can slide in the arc-shaped groove along the extension direction of the arc-shaped groove. Since the diameter of the first through hole 212 is greater than or equal to the diameter of the head 41, the first threaded fastener can be removed from the first through hole 212 or inserted into the first through hole 212, satisfying the requirements for the installation and removal of the first threaded fastener.

[0030] In some embodiments, such as Figure 4 As shown, the front of the vehicle 10 includes a first mounting portion 11 and two support portions 12, which are arranged at intervals. The two ends of the first mounting portion 11 are respectively connected to one end of each of the two second support portions 12. A functional module 30 is disposed on the first mounting portion 11, and a sliding member 40 is connected to the end of each support portion 12 away from the first mounting portion 11. Compared to a traditional front of the vehicle 10 with a single support column, the front of the vehicle 10 in this embodiment includes a first mounting portion 11 and two support portions 12, with an overall shape resembling a U-shape. The first mounting portion 11 is supported by the two support portions 12, thereby improving structural stability. When only one of the connecting portions 21 has an arc-shaped groove, only one of the two support portions 12 is connected to the sliding member 40. When both connecting portions 21 have arc-shaped grooves, both support portions 12 are connected to the sliding member 40, and the two sliding members 40 are slidably connected to the arc-shaped grooves of the two connecting portions 21 respectively. The first mounting portion 11 can be fixed to the support portion 12 with screws. The support part 12 may be equipped with an indicator light 91, a network cable interface 92, a charging port 93, etc.

[0031] In some embodiments, such as Figure 4 As shown, the vehicle head 10 also includes a second mounting portion 13. The two opposite ends of the second mounting portion 13 are respectively connected to two support portions 12. The second mounting portion 13 is equipped with functional components, including at least one of a display screen 51, a speaker 52, buttons, knobs, and light-emitting elements. Specifically, the functional components shown in the figure include a display screen 51, a speaker 52, a key switch knob 53, a start button 54, an emergency stop knob 55, and a reset button 56. When using the unmanned transport vehicle body 100, the user can obtain the working status of the unmanned transport vehicle body 100 and control the unmanned transport vehicle body 100 through the functional components on the second mounting portion 13. The second mounting portion 13 can be fixed to the support portion 12 with screws.

[0032] In some embodiments, the first mounting portion 11 has a first receiving cavity, and the support portion 12 has a second receiving cavity. The second receiving cavity communicates with the first receiving cavity. A first cable connecting the functional module 30 and the movable vehicle body 20 is disposed in both the first and second receiving cavities. By forming the first receiving cavity in the first mounting portion 11 and the second receiving cavity in the support portion 12, the first cable connecting the functional module 30 and the movable vehicle body 20 is disposed in both the first and second receiving cavities to prevent the first cable from being exposed, thereby protecting the first cable and effectively preventing it from being affected by the external environment. This also improves the aesthetics of the unmanned transport vehicle body 100. Specifically, the unmanned transport vehicle body 100 also includes a second cable, which is disposed in the second receiving cavity. Both ends of the second cable are connected to the functional component and the movable vehicle body 20, respectively. By disposing of the second cable connecting the functional component and the movable vehicle body 20 in the second receiving cavity, the second cable is prevented from being exposed, thus protecting it and improving the aesthetics of the unmanned transport vehicle body 100.

[0033] When packaging the Automated Guided Vehicle (AGV) body 100, it is not necessary to disassemble the vehicle head 10 from the movable body 20, nor to disconnect the first cable connecting the functional module 30 and the movable body 20, nor the second cable connecting the functional component and the movable body 20. Simply rotate the vehicle head 10 relative to the movable body 20 to a second position, reducing the height of the vehicle head 10 to facilitate packaging. Upon receiving the product, the customer does not need to reinstall the vehicle head 10 onto the movable body 20, nor reconnect the two ends of the first cable to the functional module 30 and the movable body 20, nor reconnect the two ends of the second cable to the functional component and the movable body 20. Simply rotating the vehicle head 10 from the second position to the first position allows the AGV body 100 to be used normally, thus improving installation convenience.

[0034] In some embodiments, combined with Figure 3 and Figure 4As shown, the front of the vehicle 10 is provided with a second threaded hole 121, and the connecting part 21 also includes a second through hole 213. The unmanned transport vehicle body 100 also includes a second threaded fastener 60. When the front of the vehicle 10 is in the first position, the second threaded fastener 60 is used to pass through the second through hole 213 and be threadedly connected to the second threaded hole 121, so that the front of the vehicle 10 is fixed to the movable body 20. When the user receives the product, he first rotates the front of the vehicle 10 from the second position to the first position, and then passes the second threaded fastener 60 through the second through hole 213 of the connecting part 21 and then threadedly connects it to the second threaded hole 121 of the front of the vehicle 10, thereby fixing the front of the vehicle 10 to the movable body 20, ensuring that the front of the vehicle 10 is stably in the first position and will not rotate arbitrarily, thereby ensuring that the functional module 30 is stably in the normal working position, and also preventing the front of the vehicle 10 from accidentally tipping over and colliding with the movable body 20. Specifically, the second threaded hole 121 is provided at the end of the support part 12 of the front of the vehicle 10 away from the first mounting part 11.

[0035] In some embodiments, combined with Figure 3 and Figure 4 As shown, the front of the vehicle 10 has third threaded holes 122 on both opposite sides, and the connecting part 21 has a third through hole 214. The unmanned transport vehicle body 100 also includes a third threaded fastener 70, which passes through the third through hole 214 and is threadedly connected to the third threaded hole 122. The front of the vehicle 10 can rotate relative to the movable body 20 around the third threaded fastener 70. When the third threaded fastener 70 is not fully tightened, it can prevent the front of the vehicle 10 from disengaging from the movable body 20, while still allowing the front of the vehicle 10 to rotate relative to the movable body 20 around the third threaded fastener 70. Specifically, the third threaded hole 122 is located at the end of the support part 12 of the front of the vehicle 10 away from the first mounting part 11.

[0036] In some embodiments, the third threaded fastener 70 extends into the second mounting cavity, such as... Figure 3 As shown, the unmanned transport vehicle body 100 also includes a locking nut 80, which is disposed in the second mounting cavity of the support portion 12 and threaded onto the third threaded fastener 70. By providing the locking nut 80 in the second mounting cavity of the support portion 12 and threading the locking nut 80 onto the third threaded fastener 70, the loosening and falling off of the third threaded fastener 70 is effectively prevented, thus avoiding the detachment of the vehicle head 10 from the movable body 20.

[0037] In some embodiments, such as Figure 3 As shown, the connecting part 21 is also provided with a hook hole 215, which is used to connect with a lifting device to lift the unmanned transport vehicle body 100 by the lifting device.

[0038] In some embodiments, such as Figure 2As shown, the movable vehicle body 20 has a support surface 22, which faces upwards. When the front of the vehicle 10 is in the second position, the support portion 12 of the front of the vehicle 10 is placed on the support surface 22. By providing the support surface 22 on the movable vehicle body 20, when the front of the vehicle 10 is in the second position, the support portion 12 of the front of the vehicle 10 can be placed on the support surface 22, thereby supporting the front of the vehicle 10 and making the front of the vehicle 10 stably in the second position.

[0039] Combination Figure 1 and Figure 2 As shown in the illustration, this application also provides an unmanned transport vehicle, including a cargo-carrying mechanism 200 and an unmanned transport vehicle body 100 as described in any of the above embodiments. The cargo-carrying mechanism 200 is connected to a movable body 20 and is driven by the movable body 20 to move and transport goods. Using the aforementioned unmanned transport vehicle body 100, packaging the unmanned transport vehicle body 100 does not require disassembling the vehicle head 10 from the movable body 20, nor does it require disconnecting the first cable connecting the functional module 30 and the movable body 20. Simply rotating the vehicle head 10 relative to the movable body 20 to a second position reduces the height of the vehicle head 10, facilitating packaging of the unmanned transport vehicle body 100. When the customer receives the product, there is no need to reinstall the vehicle head 10 onto the movable body 20, nor is it necessary to rewire the functional module 30 and the movable body 20. Simply rotating the vehicle head 10 from the second position to the first position puts the functional module 30 in a normal working position, and the unmanned transport vehicle body 100 can be used normally, thereby improving installation convenience.

[0040] Specifically, the unmanned transport vehicle shown in the figure is an AGV (Automated Guided Vehicle) forklift. Its cargo-carrying mechanism 200 includes forks, which are used to carry goods. The movable body 20 moves the forks to move, thereby realizing the handling of goods. The drive device installed in the movable body 20 is connected to the forks and can drive the forks to move up and down, thereby realizing the stacking of goods.

[0041] It should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
