[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0039] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0040] like Figure 1 As shown, the shuttle vehicle 1 of the embodiment of the present application includes a vehicle body 10, a driving assembly 20 and a fork 40, the fork 40 is telescopically connected to the vehicle body 10, the driving assembly 20 is arranged on the vehicle body 10, and the driving assembly 20 is drivingly connected to the fork 40 for driving the fork 40 to be telescopic.

[0041] The driving assembly 20 includes a motor 25, a driving shaft 21, a synchronous belt assembly 27, and an expansion sleeve 23. The motor 25 is arranged on the vehicle body 10 and connected to one axial end of the driving shaft 21. When the motor 25 is started, it can drive the driving shaft 21 to rotate. The driving shaft 21 is driven and connected to the fork 40 through the synchronous belt assembly 27. The synchronous belt assembly 27 may include a synchronous belt 26, a pulley 22 and a wheel seat 24, the wheel seat 24 is arranged on the vehicle body 10, the pulley 22 is rotatably connected to the wheel seat 24, and is sleeved on the outer periphery of the driving shaft 21 through the expansion sleeve 23, and the synchronous belt 26 is wound around the outer periphery of the pulley 22.

[0042] The pulley 22 can be connected by a bearing 50 ( Figure 3 ) is connected to the wheel seat 24, so as to increase the rigidity of the pulley 22. The bearing 50 can be a deep groove ball bearing, but is not limited thereto.

[0043] In the embodiment of the present application, the number of expansion sleeves 23, synchronous belt assemblies 27 and forks 40 are all two, and the two synchronous belt assemblies 27 are respectively connected to the two forks 40. The pulley 22 of one synchronous belt assembly 27 is sleeved on the outer periphery of one axial end of the drive shaft 21 through an expansion sleeve 23, and the pulley 22 of the other synchronous belt assembly 27 is sleeved on the outer periphery of the other axial end of the drive shaft 21 through another expansion sleeve 23. In this way, the drive shaft 21 can synchronously drive the two pulleys 22 to rotate, thereby driving the two forks 40 to synchronously extend and retract.

[0044] The synchronous belt assembly 27 may further include a tensioning wheel 28, which is disposed near the pulley 22, and the synchronous belt 26 is wound around the outer circumference of the tensioning wheel 28. By providing the tensioning wheel 28, the tension of the synchronous belt 26 can be controlled.

[0045] As described in the background technology, when the fastening screws of the expansion sleeve 23 are tightened, the pulley 22 will rotate accordingly. In the related art, in order to prevent the pulley 22 from rotating synchronously, the synchronous belt 26 or the fork 40 is usually pulled by hand, and the rotation of the pulley 22 is limited by the tooth structure between the synchronous belt 26 and the pulley 22. However, since the synchronous belt 26 is relatively soft and the synchronous belt 26 or the fork 40 cannot be firmly pulled by hand, the fastening screws of the expansion sleeve 23 are not tightened in place. After the shuttle 1 has been used for a long time, the expansion sleeve 23 may become loose, thereby affecting the stability of the extension and retraction of the fork 40, resulting in a failure in picking up goods.

[0046] The shuttle vehicle 1 of the embodiment of the present application further includes a locking assembly 30 , which is disposed on the vehicle body 10 and is used to lock or release the pulley 22 .

[0047] The shuttle vehicle 1 of the embodiment of the present application includes a locking assembly 30 disposed on the vehicle body 10. When the fastening screw of the expansion sleeve 23 needs to be tightened or loosened, the locking assembly 30 locks the pulley 22 to prevent the pulley 22 from rotating, so as to prevent the pulley 22 from rotating and affecting the disassembly and assembly of the fastening screw of the expansion sleeve 23, thereby ensuring that the expansion sleeve 23 is disassembled and assembled in place. In addition, when the expansion sleeve 23 is adjusted, the locking assembly 30 releases the pulley 22 so that the pulley 22 can continue to rotate normally.

[0048] In one embodiment, the motor 25 is located at one axial end of the drive shaft 21, and the locking assembly 30 is located at the other axial end of the drive shaft 21. In other words, the locking assembly 30 is used to lock or release the pulley 22 away from the motor 25 of the two pulleys 22, that is, the pulley 22 locked or released by the locking assembly 30 is the slave pulley.

[0049] It is understandable that the locking assembly 30 can be connected to the vehicle body 10 or to the wheel seat 24, and this application does not limit this. Next, the locking assembly 30 is described by taking the locking assembly 30 connected to the wheel seat 24 as an example.

[0050] like Figure 2 and Figure 3 As shown, the locking assembly 30 includes an adapter shaft 31 and a locking member 32 . The adapter shaft 31 is fixedly connected to the pulley 22 . The locking member 32 is connected to the wheel seat 24 and at least partially covers the outer circumference of the adapter shaft 31 for locking or releasing the adapter shaft 31 .

[0051] In one embodiment, the adapter shaft 31 includes a shaft portion 311 and a flange portion 312 , and the outer periphery of the shaft portion 311 is at least partially covered by the locking member 32 ; the flange portion 312 is connected to the outer peripheral surface of the shaft portion 311 , and the flange portion 312 is fixedly connected to the pulley 22 via a fastener 313 .

[0052] In one embodiment, one axial end of the shaft portion 311 extends into the pulley 22, and the other axial end of the shaft portion 311 is covered by the locking member 32. Of course, in other embodiments, the shaft portion 311 may not extend into the pulley 22.

[0053] Please continue reading Figure 3 and Figure 3 The locking member 32 includes a locking member 321 and an adjusting member 322. The locking member 321 has two symmetrically arranged locking parts 3211. There is a gap 3214 between the surfaces of the two locking parts 3211 facing each other. The shaft portion 311 of the adapter shaft 31 is passed through the two locking parts 3211; the adjusting member 322 is connected to the two locking parts 3211 and is used to adjust the size of the gap 3214.

[0054] It is understandable that when the adjusting member 322 reduces the gap 3214 between the two locking portions 3211, the two locking portions 3211 clamp the shaft portion 311 of the adapter shaft 31, so that the locking member 321 locks the adapter shaft 31. When the adjusting member 322 increases the gap 3214 between the two locking portions 3211, the shaft portion 311 is not clamped by the two locking portions 3211, so that the locking member 321 releases the adapter shaft 31.

[0055] In one embodiment, the adjusting member 322 is a bolt, each locking portion 3211 has a threaded hole, and the bolt is screwed into the two threaded holes. By designing the adjusting member 322 as a bolt and providing a threaded hole on the locking portion 3211, it is convenient for the operator to adjust the size of the gap 3214.

[0056] In a modified embodiment, one of the two locking parts 3211 has a threaded hole, and the other has a smooth hole, the bolt is passed through the smooth hole and screwed with the threaded hole. The cap of the bolt abuts against the locking part 3211 having the smooth hole.

[0057] In another variant embodiment, each locking portion 3211 has a light hole, a bolt is passed through two light holes, a cap of the bolt abuts against one of the locking portions 3211 , and a nut is provided at the other end of the bolt.

[0058] like Figure 3 As shown, the surfaces of the two locking parts 3211 facing each other are provided with grooves 3213 , and the shape of each groove 3213 is adapted to the outer peripheral surface shape of the shaft portion 311 of the adapter shaft 31 ; the shaft portion 311 of the adapter shaft 31 is inserted between the two grooves 3213 .

[0059] In the embodiment of the present application, the shape of the groove 3213 is adapted to the shape of the outer circumferential surface of the adapter shaft 31, so that the adapter shaft 31 can be embedded in the two grooves 3213. On the one hand, when the locking member 321 locks the adapter shaft 31, the contact area between the groove wall surfaces of the two grooves 3213 and the outer circumferential surface of the adapter shaft 31 is larger, thereby improving the locking force; on the other hand, when the locking member 321 releases the adapter shaft 31, the groove 3213 will not interfere with the movement of the adapter shaft 31.

[0060] Furthermore, the groove wall surface of each groove 3213 is covered with a wear-resistant layer 33, and the wear-resistant layer 33 is made of wear-resistant material. By arranging the wear-resistant layer 33 on the groove wall surface of the groove 3213, it is possible to prevent the groove wall of the groove 3213 from wearing and affecting the locking force of the locking portion 3211.

[0061] The present application also provides a three-dimensional warehouse system, including the shuttle vehicle 1 of any of the above embodiments. Since the shuttle vehicle 1 of any of the above embodiments is included, the three-dimensional warehouse system of the present application embodiment has all the advantages and beneficial effects of any of the above embodiments, which will not be repeated here.

[0062] In summary, the shuttle vehicle 1 and the stereoscopic storage system of the embodiment of the present application have at least the following advantages and

[0063] Beneficial effects:

[0064] The shuttle vehicle 1 of the embodiment of the present application includes a locking assembly 30 disposed on the vehicle body 10. When the fastening screw of the expansion sleeve 23 needs to be tightened or loosened, the locking assembly 30 locks the pulley 22 to prevent the pulley 22 from rotating, so as to prevent the pulley 22 from rotating and affecting the disassembly and assembly of the fastening screw of the expansion sleeve 23, thereby ensuring that the expansion sleeve 23 is disassembled and assembled in place. In addition, when the expansion sleeve 23 is adjusted, the locking assembly 30 releases the pulley 22 so that the pulley 22 can continue to rotate normally.
