[0002] As market demand for intelligent vertical warehouse solutions continues to grow, automated vertical warehouse solutions based on shuttles are gaining widespread adoption and maturing.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] The embodiment of the present application provides a novel four-way shuttle vehicle, which can solve the problem in the related art that the two-way shuttle vehicle with fork adjustment cannot travel in the horizontal and vertical dimensions to reach any storage location in the vertical warehouse.

[0029] Since the two-way shuttle with fork adjustment in the existing technology can only achieve two-way movement and cannot move freely in four directions to reach any storage position in the warehouse, a new four-way shuttle is designed on the basis of the original two-way shuttle with fork adjustment. The top of the shuttle can adjust the spacing of the forks to adapt to the clamping of goods of different sizes. Secondly, a single motor is used inside to simultaneously drive the driving wheels in the horizontal and vertical directions, so that the shuttle can move freely in the vertical and horizontal directions; thereby solving the problem that the two-way shuttle with fork adjustment in the existing technology cannot travel in the horizontal and vertical dimensions to reach any storage position in the vertical warehouse.

[0030] refer to Figure 1-8A novel four-way shuttle vehicle comprises: a vehicle frame 2, on which longitudinal drive wheels 21 and longitudinal driven wheels 22 are rotatably provided at both ends in the longitudinal direction, and transverse drive wheels 23 and transverse driven wheels 24 are rotatably provided at both ends in the transverse direction; a first longitudinal transmission shaft 31, one end of which is connected to a main gearbox 4, and the other end is connected to a longitudinal drive wheel 21 through a sub-gearbox 5; the main gearbox 4 is connected to a travel drive motor 1; a second longitudinal transmission shaft 32, which is in transmission connection with the main gearbox 4, and one end of which is also connected to the longitudinal drive wheel 21, and the other end is connected to a cross commutator 6; a transverse reversing transmission shaft 33, which is in transmission connection with the cross commutator 6, and each end of which is connected to a transverse drive wheel 23.

[0031] With this structural design, the frame 2 is the basic structural shell of the four-way shuttle, supporting all drive and transmission components. One end of the first longitudinal transmission shaft 31 is connected to the main gearbox 4, and the other end is connected to the longitudinal drive wheel 21 through the auxiliary gearbox 5. Through gear transmission, the travel drive motor 1 transmits power to the longitudinal drive wheel 21; the second longitudinal transmission shaft 32 is transmission-connected to the main gearbox 4, and one end of which is connected to the other longitudinal drive wheel 21, driving the longitudinal drive wheel 21 to rotate, further driving the longitudinal driven wheel 22 to rotate together, thereby realizing the longitudinal movement of the shuttle vehicle. Secondly, the other end is connected to the transverse reversing transmission shaft 33 through the cross commutator 6, and the two ends of the transverse reversing transmission shaft 33 are connected to the transverse drive wheels 23. Therefore, the travel drive motor 1 can drive the rotation of the transverse drive wheel 23, further driving the transverse driven wheel 24 to rotate together, thereby realizing the transverse movement of the shuttle vehicle. That is, based on the existing technology, a single motor is used in the bidirectional shuttle vehicle frame 2 with fork spacing adjustment to simultaneously drive the drive wheels in both transverse and longitudinal directions, so that the shuttle vehicle can move freely in the longitudinal and transverse directions, greatly improving the operational flexibility. The invention solves the problem in the prior art that the bidirectional shuttle vehicle with fork adjustment cannot travel in both horizontal and vertical dimensions to reach any storage position in the vertical warehouse.

[0032] In some preferred embodiments, frame fixing plates 25 are provided on both sides of the top of the frame 2 in the horizontal direction, and the frame fixing plates 25 are slidably connected to the lifting plates 26 through the vertical sliding module 12; the two lifting plates 26 are connected to a lifting drive device, and the lifting drive device is used to drive the two lifting plates 26 to rise or fall along the vertical sliding module 12; the transverse driving wheel 23 and the transverse driven wheel 24 are respectively arranged on both sides of the length direction of the lifting plate 26; the cross commutator 6 is hinged to the end of the second longitudinal transmission shaft 32 away from the main gearbox 4 through the universal joint 7.

[0033] In this embodiment, frame fixing plates 25 are provided on both sides of the top of the vehicle frame 2 in the horizontal direction to support the lifting system. A lifting plate 26 is connected to the frame fixing plate 25 via a vertical sliding module 12, allowing the lifting plate to move in the vertical direction. The configuration of the lifting drive device allows for flexible and autonomous adjustment of the height of the lifting plate 26. The transverse drive wheel 23 and the transverse driven wheel 24 are provided on the lifting plate 26 to adjust their contact or disengagement with the transverse track, thereby achieving control of the shuttle's movement direction. On this basis, in order to adapt the transverse drive wheel 23 to the connection with the second longitudinal drive shaft 32 of the power source during the lifting process, a universal coupling 7 is provided between the two, allowing for articulation with the second longitudinal drive shaft 32 during the lifting process to adapt to different angles.

[0034] In some preferred embodiments, an avoidance groove is provided at the bottom of the vehicle frame fixing plate 25 to avoid the lifting and lowering of the transverse reversing transmission shaft 33 .

[0035] Through this structural design, the provision of the avoidance groove prevents the transverse reversing drive shaft 33 from interfering with the frame fixing plate 25 during the lifting movement. This design ensures the smooth operation of the lifting system and avoids collisions between components. By reserving the avoidance groove, the system can be lifted and moved laterally more flexibly.

[0036] In some preferred embodiments, the vertical sliding module 12 includes a vertical rail rod 121 and a sliding connection block 122; the two vertical rail rods 121 are respectively fixed on both sides of the length direction of the frame fixing plate 25, and the two sliding connection blocks 122 are respectively slidably connected to the corresponding vertical rail rods 121; the two ends of the lifting plate 26 in the length direction are respectively fixedly connected to the two sliding connection blocks 122.

[0037] In this embodiment, two vertical rails 121 are fixed to either side of the frame fixing plate 25 along its length. This symmetrical arrangement enhances system stability. The lifting platform 26 maintains balance during movement, minimizing tilt and sway. The combination of the sliding connection blocks 122 and the vertical rails 121 allows the lifting platform 26 to slide smoothly on the vertical rails 121, making the lifting operation smoother.

[0038] In some preferred embodiments, a fixing frame 8 is provided at the hinge between the universal joint 7 and the second longitudinal transmission shaft 32; the fixing frame 8 is provided with upper and lower fixed rectangular grooves, the lower fixed rectangular groove is for the second longitudinal transmission shaft 32 to pass through and limit it, and the upper fixed rectangular groove is for the first longitudinal transmission shaft 31 to pass through and limit it.

[0039] Through this structural design, the fixed frame 8 not only provides a support position for the two transmission shafts, but also increases the overall structural strength of the system. Its design takes into account the various forces applied to the shafts, ensuring that the hinge will not loosen due to vibration or load during operation. The fixed rectangular groove located at the bottom is specifically used to limit the second longitudinal transmission shaft 32 to ensure the stability of the shaft during braking. This design can effectively prevent the transmission shaft from shifting, while providing the necessary support, reducing wear and potential failure risks. The fixed rectangular groove located at the top is intended to limit the displacement of the first longitudinal transmission shaft 31, ensuring that the relative position between the two longitudinal transmission shafts always remains fixed.

[0040] In some preferred embodiments, an auxiliary rectangular groove 27 is provided on the lifting plate 26; the lifting drive device includes a reversing transmission shaft 34 and a lifting power assembly, the reversing transmission shaft 34 is connected to the lifting power assembly, and both ends thereof are transmission-connected with a cam assembly 9; the cam assembly 9 slides horizontally in the auxiliary rectangular groove 27 to follow the rotation of the reversing transmission shaft 34, and at the same time drives the lifting plate 26 to rise or fall along the vertical sliding module 12.

[0041] Through this structural design, the auxiliary rectangular slot 27 provides a stable trajectory for the cam assembly 9, ensuring its accurate guidance during the lifting process. This structural design enables the lifting plate 26 to move smoothly in the vertical direction; the reversing drive shaft 34 connects the two lifting plates 26 and drives it to rotate through the connection cam assembly 9, so that the cam assembly 9 can slide in the auxiliary rectangular slot 27, thereby converting the rotational motion of the cam assembly 9 into the vertical reciprocating motion of the lifting plate 26; the cam assembly 9 can slide freely in the auxiliary rectangular slot 27 and dynamically adjust the height of the lifting plate according to the rotation of the reversing drive shaft 34, effectively controlling the raising and lowering of the lifting plate 26 and achieving precise positioning at different heights.

[0042] In some preferred embodiments, the cam assembly 9 includes an eccentric cam 91 and a cam follower 92; the eccentric cam 91 is a cylindrical structure, the bottom surface of which is fixedly connected to one end surface of the reversing drive shaft 34, and the cam follower 92 is fixedly connected to the arc edge of the top surface, and the vertical projection of the cam follower 92 does not overlap with the vertical projection of the eccentric cam 91; the cam follower 92 slides horizontally in the auxiliary rectangular groove 27.

[0043] In this embodiment, the eccentric cam 91 adopts a cylindrical structure, which enables it to evenly drive the cam follower 92 to rotate during rotation. It is important to note that the vertical projections of the cam follower 92 and the eccentric cam 91 do not overlap. This design is crucial to improving the stability of the system. This effectively avoids interference during operation. The cam follower 92 can fit into the auxiliary rectangular groove 27, ensuring that the cam follower 92 can move freely in the auxiliary rectangular groove 27, thereby achieving precise control of the lifting plate 26. The compactness of this design means that it occupies less space, making the device easier to integrate into other systems and also contributing to the miniaturization of the overall device.

[0044] In some preferred embodiments, the lifting power assembly includes a reversing reducer 10 and a lifting drive motor 11 ; the reversing reducer 10 is in transmission connection with the reversing drive shaft 34 , and the lifting drive motor 11 is in transmission connection with the reversing reducer 10 .

[0045] This structural design establishes a direct transmission connection between the reversing reducer 10 and the eccentric cam 91 via the reversing drive shaft 34. This connection ensures smooth power transmission; through the close cooperation between the reversing reducer 10 and the lifting drive motor 11, the reversing drive shaft 34 can be efficiently driven to achieve the lifting and lowering of the lifting plate 26.

[0046] In some preferred embodiments, a fixed fork 13 and a movable fork 14 are laterally provided at the top of the frame 2 and between the two frame fixing plates 25; the movable fork 14 is connected to a telescopic drive assembly to drive the movable fork 14 away from or close to the fixed fork 13; a distance sensor is provided on the movable fork 14 to detect the distance between the fixed fork 13 and the movable fork 14.

[0047] In this embodiment, the mobile fork 14 can move away from or closer to the fixed fork 13 by connecting to the telescopic drive assembly. This feature greatly enhances the flexibility of the loading and unloading process and can adapt to cargo of different specifications and sizes. Figure 6 The maximum distance between the fixed fork 13 and the mobile fork 14 that can accommodate cargo is M1, and the minimum distance is M2. The telescopic drive assembly can be a drive motor, fixedly mounted on the top of the frame 2, on the side of the mobile fork 14 away from the fixed fork 13. Its power output is connected to a telescopic rod, the other end of which is fixed to the mobile fork 14. The drive motor and distance sensor are both connected to the controller signal. The drive motor drives the telescopic rod to extend and retract longitudinally, driving the mobile fork 14 toward or away from the fixed fork 13, thereby adjusting the required distance to facilitate loading and unloading of various types of cargo. The distance sensor installed on the mobile fork 14 can monitor the distance between the fixed fork 13 and the mobile fork 14 in real time. Through real-time feedback and linkage with the control system, automated control is achieved.

[0048] In some preferred embodiments, both the movable fork 14 and the fixed fork 13 are hingedly provided with a cargo support rod 15 .

[0049] Through this structural design, the cargo support rod 15 is fixed to the mobile fork 14 and the fixed fork 13 in a hinged manner, which can achieve flexible angle adjustment. When not in use, it can be hinged and vertically retracted. When it is needed to clamp and fix cargo, it can be hinged and lowered to provide bottom support for the clamped cargo, effectively distribute the weight of the cargo, increase the firmness of the cargo, and reduce the risk of cargo slipping and falling.

One end of the first longitudinal transmission shaft 31 is connected to the main gearbox 4, and the other end is connected to the longitudinal drive wheel 21 through the auxiliary gearbox 5. Through gear transmission, the travel drive motor 1 transmits power to the longitudinal drive wheel 21; the second longitudinal transmission shaft 32 is transmission-connected to the main gearbox 4, and one end of which is connected to the other longitudinal drive wheel 21, driving the longitudinal drive wheel 21 to rotate, further driving the longitudinal driven wheel 22 to rotate together, thereby realizing the longitudinal movement of the shuttle vehicle. Secondly, the other end is connected to the transverse reversing transmission shaft 33 through the cross commutator 6, and the two ends of the transverse reversing transmission shaft 33 are connected to the transverse drive wheels 23. Therefore, the travel drive motor 1 can drive the rotation of the transverse drive wheel 23, further driving the transverse driven wheel 24 to rotate together, thereby realizing the transverse movement of the shuttle vehicle. That is, based on the existing technology, a single motor is used in the bidirectional shuttle vehicle frame 2 with fork spacing adjustment to simultaneously drive the drive wheels in both transverse and longitudinal directions, so that the shuttle vehicle can move freely in the longitudinal and transverse directions, greatly improving the operational flexibility.
