Description

Technical Field

[0001] This application relates to the field of logistics sorting technology, and more specifically, to a pallet device and a sorting transport vehicle. Background Technology

[0002] Sorting is the process in logistics transportation of identifying, classifying, and allocating batches of items to designated locations based on preset standards (such as order requirements, item attributes, delivery addresses, etc.). Currently, sorting typically uses pallet-type transport vehicles, where items can be placed on the pallets. After the transport vehicle carrying the items moves to its destination, the pallets tilt to unload the items. In existing technology, the pallets can only tilt in one direction. When items need to be unloaded from another direction, the transport vehicle needs to rotate at a certain angle before the pallets can tilt to unload the items to the designated location, resulting in low sorting efficiency. Utility Model Content

[0003] The main objective of this application is to provide a pallet device and a sorting transport vehicle to solve the problem of low sorting efficiency in the prior art.

[0016] Furthermore, the guiding trajectory includes:

[0017] A horizontally moving segment, which is parallel to the upper surface of the base;

[0018] A first lifting section is connected to the horizontal moving section and extends a predetermined length in a direction away from the base;

[0019] The second lifting section is connected to the horizontal moving section and extends a predetermined length in a direction away from the base.

[0020] Furthermore, the first lifting segment includes an arc segment, which is connected to the horizontal moving segment.

[0021] Furthermore, the second lifting segment includes an arc segment connected to the horizontal moving segment.

[0022] Furthermore, the connecting portion includes:

[0023] A rolling part, which is embedded in the guide groove;

[0024] A connector, one end of which is fixedly connected to the bottom of the tray, and the other end is rotatably connected to the rolling part.

[0025] Furthermore, the speed-multiplying component includes:

[0026] A rotating component, rotatably connected to the tray;

[0027] A speed-multiplying component is connected between the drive assembly and the rotating component.

[0028] Furthermore, the speed-multiplying component includes:

[0029] A power input unit, which is connected to the drive assembly;

[0030] A speed-multiplying transmission unit is connected between the power input unit and the base to apply a force to the rotating component in the same direction of movement as the power input unit.

[0031] Furthermore, a first roller and a second roller are respectively provided on opposite sides of the power input section, and both the first roller and the second roller rotate around their own axis;

[0032] The speed-multiplying transmission unit includes:

[0033] A belt, which is fitted onto the first roller and the second roller and surrounds the outer periphery of the power input section;

[0034] A fixed bracket is fixedly connected between the belt and the base;

[0035] A movable bracket is fixedly connected between the belt and the rotating component, and the movable bracket and the fixed bracket are respectively located on opposite sides of the belt;

[0036] The power input unit moves to drive the belt to apply a force to the movable bracket in the same direction as the movement of the power input unit, so that the movable bracket moves relative to the power input unit.

[0037] Furthermore, the speed-multiplying component also includes:

[0038] The first slide rail, on which the movable bracket is slidably connected.

[0039] Furthermore, the rotating component includes:

[0040] A bushing, which is connected to the speed multiplier component;

[0041] A rotating shaft passes through the bushing, and the portion of the rotating shaft outside the bushing is connected to the tray.

[0042] Furthermore, the driving component includes:

[0047] On the other hand, this application also provides a sorting and transport vehicle, including the aforementioned pallet device.

[0048] In this application, by setting a pallet and a drive mechanism on the base, the drive mechanism can drive the pallet to switch between a first position, a second position, and a third position. When an item needs to be unloaded to a position near the first side of the pallet, the drive mechanism drives the pallet to move closer to the first side of the base and flips the pallet to unload the item from the pallet. When an item needs to be unloaded to a position near the second side of the pallet, the drive mechanism drives the pallet to move closer to the second side of the base and flips the pallet to unload the item from the pallet. When the unloading position of the item does not correspond to the flipping direction of the pallet, the sorting transport vehicle does not need to make a turning operation; it only needs to adjust the position of the pallet to unload the item to the required unloading position, which significantly speeds up the unloading speed of the item, reduces the movement path of the sorting transport vehicle, shortens the sorting time, and improves the sorting efficiency. In addition, the pallet can be flipped to both sides of the base to unload the item, reducing the flexibility requirements of the sorting transport vehicle during the item sorting process. When the pallet is in the second position, it is located between the first and second sides of the base and parallel to the upper surface of the base. At this time, items can be placed on the pallet. The pallet has high stability and can effectively prevent items from falling out of the pallet during the movement of the sorting and transport vehicle, ensuring that the items can be smoothly transported to the unloading position.

[0069] like Figures 1 to 11 As shown, this application provides a pallet device. The pallet device includes a base 10, a pallet 20, and a drive mechanism 30. Along the length of the base 10 (e.g., ...), Figure 1 (In the direction indicated by the middle arrow X), the base 10 has a first side 11 and a second side 12 disposed opposite to each other. The tray 20 is movable relative to the base 10 along its length. The tray 20 has a first position where it moves close to the first side 11 of the base 10 and flips away from the second side 12; a second position where it moves between the first side 11 and the second side 12 and is parallel to the upper surface of the base 10; and a third position where it moves close to the second side 12 of the base 10 and flips away from the first side 11. A drive mechanism 30 is disposed on the base 10 and connected to the tray 20. The drive mechanism 30 drives the tray 20 to switch between the first position, the second position, and the third position.

[0070] In this embodiment, by setting a tray 20 and a drive mechanism 30 on the base 10, the drive mechanism 30 can drive the tray 20 to switch between a first position, a second position, and a third position. When an item needs to be unloaded to a position near the first side 11 of the tray 20, the drive mechanism 30 drives the tray 20 to move closer to the first side 11 of the base 10 and flips the tray 20 to unload the item from the tray 20. When an item needs to be unloaded to a position near the second side 12 of the tray 20, the drive mechanism 30 drives the tray 20 to move closer to the second side 12 of the base 10 and flips the tray 20 to unload the item from the tray 20. When the unloading position of the item does not correspond to the flipping direction of the tray 20, the sorting transport vehicle does not need to make a turning operation to unload the item to the required unloading position, which significantly speeds up the unloading speed of the item, reduces the movement path of the sorting transport vehicle, shortens the sorting time, and improves the sorting efficiency. Furthermore, the pallet 20 can be flipped to either side of the base 10, reducing the flexibility requirements of the sorting transport vehicle during the sorting process. When the pallet 20 is in the second position, it is located between the first side 11 and the second side 12 of the base 10 and parallel to the upper surface of the base 10. At this time, items can be placed on the pallet 20. The pallet 20 has high stability and can effectively prevent items from falling off the pallet 20 during the movement of the sorting transport vehicle, ensuring that items can be smoothly transported to the unloading position.

[0071] like Figures 1 to 3As shown, in one embodiment, the drive mechanism 30 includes a drive component 31, a speed-multiplying component 32, and a guide component 33. The drive component 31 is disposed on the base 10. The speed-multiplying component 32 is disposed on the base 10. The speed-multiplying component 32 is connected between the drive component 31 and the tray 20, and drives the tray 20 to move along the length direction of the base 10 under the drive of the drive component 31. The guide component 33 is connected between the base 10 and the tray 20 to drive the tray 20 to move and rotate under the guidance of a predetermined guide trajectory 330. The tray 20 moves along the length direction of the base 10 and moves and rotates under the guidance of the guide trajectory 330 to switch between a first pose, a second pose, and a third pose. The drive component 31 provides a stable power source for the speed-multiplying component 32, which can accurately transmit power, enabling the speed-multiplying component 32 to drive the tray 20 to reciprocate along the length direction of the base 10 under the drive of the drive component 31. During the reciprocating movement of the pallet 20 along the length of the base 10, the guide component 33 drives the pallet 20 to rotate under the guidance of a predetermined guide trajectory 330, ensuring that the pallet 20 can accurately switch between the first, second, and third positions, effectively preventing the pallet 20 from deviating or jamming. Furthermore, during the switching of the pallet 20 between the first, second, and third positions by the drive component 31, the pallet 20 only undergoes linear and rotating movements under the action of one drive component 31, improving the assembly efficiency of the drive mechanism 30, reducing production costs, and minimizing the space required for installing the drive mechanism 30. The base 10 provides stable support for the drive component 31, the speed-multiplying component 32, and the guide component 33, ensuring the stability of the drive mechanism 30.

[0072] like Figure 4As shown, in one embodiment, the guide assembly 33 includes a guide portion 331 and a connecting portion 332. The guide portion 331 is connected to the base 10. A guide groove 3310 is provided on the guide portion 331. The extension trajectory of the guide groove 3310 forms a guide trajectory 330, and the two ends of the guide groove 3310 extend to opposite ends of the guide portion 331 along the length direction of the base 10. One end of the connecting portion 332 is connected to the tray 20, and the other end is connected to the guide groove 3310 and can slide along the guide groove 3310 to switch the tray 20 between a first position, a second position, and a third position. The guide groove 3310 is provided on the guide portion 331, and the guide portion 331 is connected to the base 10, ensuring that the guide groove 3310 has high stability. The guide groove 3310 can accurately guide the connecting portion 332 to slide so that the tray 20 can accurately switch between the first position, the second position, and the third position. The extended trajectory of the guide groove 3310 accurately constrains the sliding trajectory of the end of the connecting part 332 away from the tray 20, ensuring that the tray 20 always moves and flips under the guidance of the predetermined guide trajectory 330. The guide trajectory 330 can also limit the flipping direction and flipping angle of the tray 20, effectively preventing the tray 20 from shifting, or the flipping angle from being too small or too large, thus helping to ensure that items can be smoothly unloaded from the tray 20.

[0073] When the tray 20 moves relative to the base 10 along its length direction under the drive of the speed-multiplying component 32 to the end near the base 10, the connecting part 332 slides along the guide groove 3310 to the end of the guide groove 3310 under the drive of the tray 20. At this time, the supporting effect of the connecting part 332 on the tray 20 decreases, and the tray 20 will flip under the guidance of the guide component 33 and the action of gravity to unload the items. In this embodiment, the connecting part 332 has a certain length so that the base 10 will not interfere with the tray 20, and the tray 20 can flip smoothly.

[0074] Specifically, the guide portion 331 can be configured as a vertical plate. The length of the vertical plate extends along the length direction of the base 10. The vertical plate can limit the tray 20 from shifting and wobbling along the width direction of the base 10. The vertical plate can also reduce the space occupied by the plate on the base 10. The vertical plate can be fixedly connected to the base 10 or integrally formed with the base 10. In one embodiment, along the thickness direction of the vertical plate (e.g., ... Figure 1(In the direction indicated by the middle arrow Y, the thickness direction of the upright plate is the same as the width direction of the base 10), and the guide groove 3310 can be disposed through the upright plate. A rolling part 3321 is provided at the end of the connecting part 332 away from the tray 20. The rolling part 3321 is located within the guide groove 3310 and slides along the guide groove 3310. The through guide groove 3310 facilitates the assembly and disassembly of the rolling part 3321 and also facilitates processing. In another embodiment, a strip-shaped blind hole is provided on the side of the upright plate. The extension trajectory of the strip-shaped blind hole forms a guide trajectory 330. The end of the connecting part 332 away from the tray 20 is located within the strip-shaped blind hole and slides along the strip-shaped blind hole. In another embodiment, a sliding guide rail can be provided on the side of the upright plate. The extension trajectory of the sliding guide rail forms a guide trajectory 330. The end of the connecting part 332 away from the tray 20 engages with the guide trajectory 330 and slides along the sliding guide rail. It is understood that the guide trajectory 330 can also be set in other forms, and this embodiment is not limited to one.

[0075] Among them, such as Figure 4 As shown, the guide trajectory 330 includes a horizontal moving segment 3311, a first lifting segment 3312, and a second lifting segment 3313. The horizontal moving segment 3311 extends along the length direction of the base 10 and is parallel to the upper surface of the base 10. The first lifting segment 3312 is connected to the first end of the horizontal moving segment 3311, and the side of the first lifting segment 3312 away from the horizontal moving segment 3311 extends along the height direction of the base 10 (e.g., ...). Figure 1The second lifting section 3313 extends a predetermined length away from the base 10 in the direction indicated by the middle arrow Z. The second lifting section 3313 is connected to the second end of the horizontal moving section 3311 opposite to the first end, and the side of the second lifting section 3313 away from the horizontal moving section 3311 extends a predetermined length away from the base 10 along the height direction of the base 10. When the connecting part 332 slides along the horizontal moving section 3311, the tray 20 is in a second position. When the connecting part 332 slides along the first lifting section 3312, the tray 20 is in a first position. When the connecting part 332 slides along the second lifting section 3313, the tray 20 is in a third position. The horizontal moving section 3311 is parallel to the upper surface of the base 10 and extends along the length direction of the base 10, so that the tray 20 is parallel to the upper surface of the base 10 in the second position, and the items inside the tray 20 can remain relatively stable, preventing the items inside the tray 20 from falling off during the movement of the sorting transport vehicle. Since the first lifting section 3312 extends away from the base 10 along the height direction of the base 10, when the connecting part 332 slides from the horizontal moving section 3311 to the first lifting section 3312, the tray 20 can actively flip towards the second side 12 away from the base 10 to unload the items. When the connecting part 332 slides from the first lifting section 3312 to the horizontal moving section 3311, the tray 20 can actively return to a second position parallel to the upper surface of the base 10. Similarly, when the connecting part 332 slides from the horizontal moving section 3311 to the second lifting section 3313, the tray 20 can precisely switch to a third position and flip towards the first side 11 away from the base 10. When the connecting part 332 slides from the second lifting section 3313 to the horizontal moving section 3311, the tray 20 can actively return to a second position parallel to the upper surface of the base 10.

[0076] The end of the connecting part 332 away from the pallet 20 slides along the guide groove 3310, which can directly drive the pallet 20 to switch between the first position, the second position and the third position. There is no need to set up other additional power equipment to drive the pallet 20 to move and flip, which simplifies the structure of the pallet 20 to achieve the flipping movement. It can also ensure that the pallet 20 moves smoothly and accurately when switching between positions, reduce the risk of failure of the drive mechanism 30 due to complex structure, and improve sorting efficiency.

[0077] In one embodiment, the first lifting segment 3312 includes an arc segment connected to the first end of the horizontal moving segment 3311. When the connecting part 332 slides between the first lifting segment 3312 and the horizontal moving segment 3311, the arc segment makes the sliding of the connecting part 332 smoother, ensuring that the tray 20 moves more smoothly during movement and flipping.

[0078] In one embodiment, the second lifting segment 3313 includes an arc segment connected to the second end of the horizontal moving segment 3311. When the connecting part 332 slides between the second lifting segment 3313 and the horizontal moving segment 3311, the arc segment makes the sliding of the connecting part 332 smoother, ensuring that the tray 20 moves more smoothly during movement and flipping. It is understood that the above embodiments can be implemented individually or simultaneously. The arc segments on both sides of the horizontal moving segment 3311 make the switching of the tray 20 between the first, second, and third positions smoother and more gradual.

[0079] like Figures 6 to 7 As shown, in one embodiment, the connecting portion 332 includes a rolling portion 3321 and a connecting member 3322. The rolling portion 3321 is embedded in the guide groove 3310 and rolls along the extension trajectory of the guide groove 3310. A connecting rod 33211 extends from the rolling portion 3321 along the width direction of the base 10. One end of the connecting member 3322 is fixedly connected to the bottom of the tray 20, and the other end is sleeved on the connecting rod 33211 and can rotate around the axis of the connecting rod 33211. During the rolling process of the rolling portion 3321 within the guide groove 3310, it drives the connecting rod 33211 to roll synchronously with the rolling portion 3321. The connector 3322 is fitted onto the connecting rod 33211. When the tray 20 switches between the first position, the second position and the third position, the connector 3322 rotates relative to the connecting rod 33211. The connector 3322 has a certain degree of rotational freedom, ensuring that the tray 20 can flexibly perform the flipping action. Moreover, the flipping action of the tray 20 is relatively smooth and gentle under the constraint of the connecting rod 33211.

[0080] Specifically, the connector 3322 can be configured as a crank, which can be configured as a T-shaped structure. The upper end of the crank is fixed to the bottom of the tray 20, and the lower end of the crank is rotatably connected to the connecting rod 33211.

[0081] The rolling part 3321 can roll along the extension trajectory of the guide groove 3310, reducing the friction between the rolling part 3321 and the guide groove 3310, reducing the resistance during the rolling process of the rolling part 3321, making the movement of the tray 20 under the guidance of the guide groove 3310 smoother and less strenuous, effectively reducing energy loss, improving the operating efficiency of the drive mechanism 30, and extending the service life of the guide assembly 33. The rolling part 3321 can be configured as a pulley, with the outer side wall of the pulley rollingly connected to the inner side wall of the guide groove 3310.

[0082] like Figure 5 As shown, in one embodiment, the drive assembly 31 includes a power component and a transmission component. The power component is connected to the base 10. The transmission component is connected between the power component and the speed-multiplying assembly 32, so that the speed-multiplying assembly 32 drives the tray 20 to move.

[0083] The transmission component 321 includes a lead screw 3211 and a nut 3212. The lead screw 3211 is disposed on the base 10 and extends along the length of the base 10. The lead screw 3211 is connected to the power component and rotates under the drive of the power component. The nut 3212 is sleeved on the lead screw 3211 and engages with the lead screw 3211.

[0084] The power component includes a drive member 311 and a drive unit. The drive member 311 is connected to the base 10. The drive unit is connected between the drive member 311 and the lead screw 3211. The drive member 311 drives the lead screw 3211 to rotate via the drive unit. Along the width direction of the base 10, the drive member 311 and the transmission component 321 are located on opposite sides of the guide assembly 33. The drive member 311 is fixed to the base 10 and transmits power to the drive unit. The drive unit, acting as a hub connecting the drive member 311 and the lead screw 3211, converts the power of the drive member 311 into torque that drives the lead screw 3211 to rotate. The nut 3212 engages with the lead screw 3211, and the rotation of the lead screw 3211 drives the nut 3212 to move linearly, thereby moving the tray 20. Meanwhile, since the drive component 311 and the transmission component 321 are located on opposite sides of the guide assembly 33, the installation space on the base 10 is fully utilized, resulting in a more compact structure.

[0085] The drive component 311 can be a motor. The drive unit includes a first fixing component, a second fixing component, and a transmission component. The first fixing component is sleeved on the output shaft of the motor. The second fixing component is sleeved on the end of the lead screw 3211. The transmission component is arranged around the outer wall of the first and second fixing components. The transmission component can be a transmission belt, chain, gear, etc.

[0086] In another embodiment, the transmission component 321 may be configured as a cylinder and piston structure, with the piston moving within the cylinder and connected to the speed multiplier assembly.

[0087] In one embodiment, the speed-multiplying component 32 includes a rotating component 322 and a speed-multiplying component 323. The rotating component 322 is rotatably connected to the tray 20. The speed-multiplying component 323 is connected between the drive component 31 and the rotating component 322. In this embodiment, the rotating component 322 is rotatably connected to the bottom of the tray 20. The speed-multiplying component 323 is connected between the nut 3212 and the rotating component 322 so that the moving speed of the tray 20 is greater than the moving speed of the nut 3212. During the rotation of the lead screw 3211 driven by the power component, the nut 3212 reciprocates relative to the lead screw 3211 along the length direction of the base 10. The speed-multiplying component 323 is connected between the nut 3212 and the rotating component 322. The nut 3212 reciprocates along the length direction of the base 10, and through the speed-multiplying component 323, drives the rotating component 322 to reciprocate along the length direction of the base 10, thereby driving the tray 20 to reciprocate along the length direction of the base 10. The connector 3322 is fixedly connected to the tray 20. During the movement of the tray 20, the connector 3322 is also moved back and forth along the length of the base 10. At the same time, the connector 3322 is constrained by the guide groove 3310. The connector 3322 also drives the tray 20 to flip when the tray 20 moves.

[0088] The speed-doubling component 323 can sequentially transfer the kinetic energy of the nut 3212 to the rotating component 322 and the tray 20, making the moving speed of the tray 20 greater than that of the nut 3212. In this embodiment, without adding other additional drive equipment or lengthening the lead screw 3211, the speed-doubling component 323 effectively lengthens the moving path and moving speed of the tray 20, improving the moving efficiency of the tray 20 and thus increasing sorting efficiency.

[0089] like Figures 8 to 9As shown, in one embodiment, the speed-multiplying component 323 includes a power input section 3231 and a speed-multiplying transmission section 3232. The power input section 3231 is connected to the nut 3212 and moves along the length of the base 10. The speed-multiplying transmission section 3232 is connected between the power input section 3231 and the base 10 to apply a force to the rotating component 322 in the same direction as the movement of the power input section 3231. The power input section 3231 can move along the length of the base 10 under the drive of the nut 3212. When the nut 3212 drives the power input section 3231 to move, the speed-multiplying transmission section 3232 can apply a force in the same direction to the rotating component 322, causing the rotating component 322 to move relative to the speed-multiplying transmission section 3232. That is, the moving speed of the rotating component 322 is the vector sum of the moving speed of the rotating component 322 relative to the speed-multiplying transmission section 3232 and the moving speed of the power input section 3231. Therefore, the rotating component 322 drives the tray 20 to move relative to the power input unit 3231. Without increasing the length and rotation speed of the lead screw 3211 or adding other driving devices, this embodiment achieves the purpose of speeding up the movement of the tray 20, thereby effectively shortening the time for the tray 20 to switch between different positions and improving the sorting efficiency of items.

[0090] Along the width direction of the base 10, the speed multiplier 323 is disposed on one side of the transmission component 321, and the nut 3212 is fixedly connected to the power input part 3231 via the connecting bracket 3213. One end of the connecting bracket 3213 is fixedly connected to the nut 3212, and the other end is bent along the width direction of the base 10 and fixed to the top of the power input part 3231.

[0091] In another embodiment, the speed transmission unit 3232 may also be configured to move relative to the power input unit 3231 under the drive of the drive device to increase the moving speed of the tray 20.

[0092] like Figures 8 to 10As shown, along the length of the base 10, a first roller 32311 and a second roller 32312 are respectively provided on opposite sides of the power input section 3231. Both the first roller 32311 and the second roller 32312 rotate around their own axes. The speed transmission section 3232 includes a belt 32321, a fixed bracket 32322, and a movable bracket 32323. The belt 32321 is sleeved on the first roller 32311 and the second roller 32312 and surrounds the outer periphery of the power input section 3231. The axial direction of the belt 32321, the axial direction of the first roller 32311, and the axial direction of the second roller 32312 are the same. The fixed bracket 32322 is fixedly connected between the belt 32321 and the base 10. One end of the movable bracket 32323 is fixedly connected to the belt 32321, and the other end is connected to the rotating component 322. Along the width direction of the base 10, the movable bracket 32323 and the fixed bracket 32322 are located on opposite sides of the belt 32321. The power input unit 3231 moves along the length direction of the base 10, driving the belt 32321 to apply a force to the movable bracket 32323 in the same direction as the power input unit 3231, causing the movable bracket 32323 to move relative to the power input unit 3231. The power unit drives the lead screw 3211 to rotate, causing the nut 3212 to move along the lead screw 3211, thereby moving the power input unit 3231 along the length direction of the base 10 with the nut 3212. The first roller 32311 and the second roller 32312 on both sides of the power input unit 3231 move with the power input unit 3231, and the belt 32321 also moves along the length direction of the base 10. Since the fixed bracket 32322 is fixed between the belt 32321 and the base 10, when the power input part 3231 moves, the connection between the belt 32321 and the fixed bracket 32322 is stationary and has zero speed relative to the base 10, while the connection between the belt 32321 and the movable bracket 32323 rotates around the outer circumference of the power input part 3231 and has a certain acceleration during the movement of the power input part 3231, thereby causing the tray 20 to also have a certain acceleration and move faster along the length of the base 10. The first roller 32311 and the second roller ensure that the part of the belt 32321 away from the fixed bracket 32322 can rotate smoothly. When the movable bracket 32323 moves close to the first roller 32311 or the second roller 32312, the speed of the movable bracket 32323 is close to the linear speed of the first roller 32311 or the second roller 32312. At this time, the moving speed of the movable bracket 32323 is relatively fast. This embodiment improves the moving speed of the pallet 20 and the sorting efficiency of the items by setting a fixed bracket 32322 on the belt 32321 to accelerate the movement of the movable bracket 32323, without lengthening the lead screw 3211, changing the rotation speed of the lead screw 3211, or setting other driving devices.Furthermore, the modular speed-multiplying component 323 is easier to disassemble and maintain, reducing its maintenance costs. The belt 32321 also offers advantages such as low noise, low cost, and stable transmission.

[0093] Specifically, the power input section 3231 can be configured as a plate-like structure, with its length extending along the length direction of the base 10. Notches 32313 are provided on both sides of the power input section 3231 along its length, and the first roller 32311 and the second roller 32312 are respectively installed in the notches 32313 on both sides of the power input section 3231. Both the first roller 32311 and the second roller 32312 can rotate relative to the mounting plate around their own axis. In this embodiment, the axial direction of the first roller 32311 and the second roller 32312 is the same as the height direction of the base 10. Both the first roller 32311 and the second roller 32312 include a mounting rod 32314, a bearing 32315, and a roller 32316. Mounting rods 32314 are inserted through the power input section 3231 along the height direction of the base 10. Bearings 32315 are sleeved on the mounting rods 32314 and located within the notch 32313. Rollers 32316 are sleeved on the outside of the bearings 32315. At least two bearings 32315 may be provided on each mounting rod 32314, and the at least two bearings 32315 are spaced apart along the length direction of the mounting rod 32314. A belt 32321 is wrapped around the outer wall of the two rollers 32316.

[0094] Specifically, the fixed bracket 32322 is located on the side of the belt 32321 opposite to the power input section 3231 along the width direction of the base 10. The first clamping plate 01 is connected to the fixed bracket 32322 to clamp the belt 32321 at least partially between the first clamping plate 01 and the fixed bracket 32322, so that the connection between the belt 32321 and the fixed bracket 32322 is stationary relative to the base 10. The movable bracket 32323 is fixedly connected to the second clamping plate 02, so that the movable bracket 32323 can be stably installed on the belt 32321.

[0095] The movement of the movable support 32323 causes the tray 20 to move along the length of the base 10. To improve the stability of the tray 20 during movement, in one embodiment, the speed-multiplying component 323 further includes a first slide rail 3233. The first slide rail 3233 is connected to the top of the transmission component 321. The length of the first slide rail 3233 extends along the length of the base 10, and the movable support 32323 is slidably connected to the first slide rail 3233. During the movement of the movable support 32323 along the length of the base 10, the bottom of the movable support 32323 engages with and slides along the first slide rail 3233. The first slide rail 3233 provides precise guidance for the movable support 32323, ensuring that the movable support 32323 does not deviate or sway during movement, making the movement trajectory of the tray 20 more stable. The first slide rail 3233 can also reduce the frictional resistance when the movable support 32323 moves, and in conjunction with the belt 32321 transmission, it can reduce energy loss and improve the transmission efficiency of the drive mechanism 30. The first slide rail 3233 is installed at the top of the transmission component 321, making the structure of the drive mechanism 30 more compact and the first slide rail 3233 will not occupy much installation space. In addition, the two ends of the first slide rail 3233 extend outside the base 10, so that when the tray 20 is flipped, the tray 20 will not interfere with the base 10, ensuring that the tray 20 can be flipped more smoothly to unload the items.

[0096] In this embodiment, a first stop portion 3214 and a second stop portion 3215 are respectively provided at both ends of the lead screw 3211 along its length. A first slide rail 3233 is fixed across the top ends of the first stop portion 3214 and the second stop portion 3215.

[0097] like Figure 11 As shown, in one embodiment, the rotating component 322 includes a bushing 3221 and a rotating shaft 3222. The bushing 3221 is connected to the speed-multiplying component 323. The rotating shaft 3222 passes through the bushing 3221 along the width direction of the base 10 and can rotate relative to the bushing 3221 along its own axis. The portion of the rotating shaft 3222 outside the bushing 3221 is connected to the tray 20. The bushing 3221 is fixedly connected to the movable bracket 32323 on the speed-multiplying component 323. The movement of the movable bracket 32323 causes the bushing 3221 to move along the length direction of the base 10, and the bushing 3221, through the rotating shaft 3222, causes the tray 20 to also move along the length direction of the base 10. Since the rotating shaft 3222 passes through the bushing 3221 along the width direction of the base 10 and can rotate around its own axis, the movement of the bushing 3221 will drive the rotating shaft 3222 and the tray 20 to move synchronously. When the tray 20 is flipped, the rotating shaft 3222 can rotate flexibly in the bushing 3221, so that the tray 20 can smoothly achieve the flipping action. The rotating shaft 3222 passes through the connector 3322 and is fixedly connected to the connector 3322.

[0098] In one embodiment, a first stop portion 3214 and a second stop portion 3215 are respectively provided on opposite sides along the length of the lead screw 3211. The transmission component 321 also includes a second slide rail 3216. The length of the second slide rail 3216 extends along the length of the base 10, and the second slide rail 3216 spans between the first stop portion 3214 and the second stop portion 3215. A nut 3212 is slidably connected to the second slide rail 3216. When the power component drives the lead screw 3211 to rotate, the nut 3212, which meshes with the lead screw 3211, moves along the length of the base 10 under the drive of the lead screw 3211. Since the nut 3212 is slidably connected to the second slide rail 3216 that bridges the first stop 3214 and the second stop 3215, the second slide rail 3216 provides precise guidance for the movement of the nut 3212, ensuring that the nut 3212 can only move linearly along the direction of the second slide rail 3216, preventing the nut 3212 from deviating or wobbling. The second slide rail 3216 effectively improves the stability and straightness of the movement of the nut 3212. At the same time, the first stop 3214 and the second stop 3215 limit the range of movement of the nut 3212, preventing the nut 3212 from falling off from both ends of the lead screw 3211.

[0099] In one embodiment, the first stop portion 3214 is provided with a limiting groove 3217. When the tray 20 is in the first position, the guide component 33 abuts against the limiting groove 3217 of the first stop portion 3214. When the tray 20 moves to the first position under the action of the drive mechanism 30, the guide component 33 moves synchronously with the tray 20. After the tray 20 flips, the guide component 33 can abut against the limiting groove 3217 of the first stop portion 3214. At this time, the limiting groove 3217 provides a stable constraint for the guide component 33, restricting the tray 20 from continuing to tilt in the direction away from the second side 12 of the base 10, so that the tray 20 is stably maintained in the first position. In another embodiment, the second stop portion 3215 is provided with a limiting groove 3217. When the tray 20 is in the third position, the guide component 33 abuts against the limiting groove 3217 of the second stop portion 3215. It is understood that the above embodiments can be implemented individually or simultaneously, and the first stop portion 3214 and the second stop portion 3215 are both provided with limit grooves 3217.

[0100] Among them, such as Figure 1 As shown, the pallet device also includes a first housing 40 and a second housing 50. Both the first housing 40 and the second housing 50 are mounted on the base 10 and surround the base 10 to form a mounting cavity. The drive mechanism 30 is located inside the mounting cavity. A clearance hole 41 is provided through the side wall of the mounting cavity. At least a portion of the upright plate and at least a portion of the connector 3322 extend out of the mounting cavity through the clearance hole 41.

[0101] On the other hand, this application also provides a sorting and transport vehicle that includes the aforementioned pallet device, and therefore, the sorting and transport vehicle incorporates all the technical effects of the aforementioned pallet device. Since the technical effects of the pallet device have already been described in detail above, they will not be repeated here. This sorting and transport vehicle can be used for sorting logistics parcels.

[0102] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0103] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
