Abstract

This invention relates to the field of parking garages, and particularly to a vehicle pallet storage and retrieval device, comprising a storage rack; a pallet seat disposed on one side of the storage rack; a lifting device disposed at the bottom of the storage rack; a first lateral movement mechanism disposed at the lifting movable end of the lifting device; and a second lateral movement mechanism disposed at the bottom of the storage rack, capable of laterally moving from the storage rack to the pallet seat. When a vehicle pallet is placed on the storage rack, the lifting device rises so that the first lateral movement mechanism contacts the underside of the vehicle pallet. The first lateral movement mechanism then moves horizontally, causing the vehicle pallet to laterally move away from the storage rack. The lifting device then lowers, bringing the vehicle pallet down and placing it on the second lateral movement mechanism.

This eliminates the need for AGVs (Automated Guided Vehicles) for transporting vehicles and retrieving / retrieving vehicle pallets in the handover area, effectively reducing downtime and improving the user experience.

Description

Technical Field

[0001] This invention relates to the field of garages, and in particular to a vehicle platform storage and retrieval device. Background Technology

[0002] With the increasing popularity of cars, parking difficulties have become a major problem hindering urban development. In order to solve this problem, intelligent automated parking garages have emerged. To improve parking and retrieval efficiency, idle car platforms in intelligent automated parking garages need to be stored in a car platform storage and retrieval device for easy access next time.

[0003] The currently used vehicle pallet storage and retrieval device is located next to the parking space. AGV (Automated Guided Vehicle) carts are required to assist in storing or retrieving pallets from this device. After parking in the designated handover area, the AGV cart transports the pallet and vehicle together. Then, the AGV cart retrieves a pallet from the storage device and places it in the handover area for the next driver. When retrieving the vehicle, if a pallet is available in the handover area, the AGV cart must remove it first so the vehicle can be transported there. The use of AGV carts for both vehicle transport and pallet replenishment / retrieval in the handover area prolongs parking and retrieval time, resulting in a poor user experience. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a vehicle pallet storage and retrieval device that eliminates the need for AGV trolleys when replenishing / retrieving vehicle pallets in the transport and handover areas, effectively reducing vehicle retrieval time and providing a better retrieval experience.

[0034] With the widespread use of cars, parking difficulties have become a major problem hindering urban development. To solve this problem, intelligent automated parking garages have emerged. Furthermore, to improve parking and retrieval efficiency, idle car platforms in intelligent automated parking garages need to be stored in a car platform storage and retrieval device for easy access later.

[0035] Currently, the vehicle pallet storage and retrieval device is located next to the parking space. AGV (Automated Guided Vehicle) carts are required to assist in storing or retrieving pallets from this device. After parking in the designated handover area, the AGV cart transports the pallet and vehicle together. Then, the AGV cart retrieves a pallet from the storage device and places it in the handover area for the next driver. When retrieving the vehicle, if a pallet is available in the handover area, the AGV cart must remove it first so the vehicle can be transported there. The use of AGV carts for both vehicle transport and pallet replenishment / retrieval in the handover area prolongs parking and retrieval time, resulting in a poor user experience.

[0036] To address the aforementioned technical problems, the present invention provides a vehicle platform storage and retrieval device.

[0037] See Figures 1 to 8 The vehicle platform storage and retrieval device includes a storage rack 100, a tray seat 200, a lifting device 300, a first lateral movement mechanism 400, and a second lateral movement mechanism 500. The storage rack 100 has a vacuum at the bottom. The tray seat 200 is located on one side of the storage rack 100. The lifting device 300 is located at the bottom of the storage rack 100. The first lateral movement mechanism 400 is located at the lifting movable end of the lifting device 300. The second lateral movement mechanism 500 is located at the bottom of the storage rack 100 and can be laterally moved from the storage rack 100 to the tray seat 200.

[0038] The vehicle pallet 001 is placed on the storage rack 100. When the vehicle pallet 001 needs to be retrieved, the lifting device 300 is raised so that the first lateral movement mechanism 400 contacts the lower side of the vehicle pallet 001 and slightly lifts the vehicle pallet 001. Then, the first lateral movement mechanism 400 moves horizontally so that the vehicle pallet 001 is moved laterally away from the storage rack 100. Then, the lifting device 300 lowers and pulls the vehicle pallet 001 down so that the vehicle pallet 001 is placed on the second lateral movement mechanism 500. Then, the second lateral movement mechanism 500 moves the vehicle pallet 001 laterally from the bottom of the storage rack 100 and places it on the pallet seat 200. In this way, when transporting vehicles and replenishing / retrieving the vehicle pallet 001 in the handover area, there is no need to use an AGV trolley, which effectively reduces the time spent stopping to retrieve vehicles and provides a better experience.

[0039] In some embodiments, the access rack 100 is a frame structure, and the two sides of the access rack 100 are provided with support racks 140 opposite each other, and the support racks 140 are provided with multiple layers of support platforms 141.

[0040] Specifically, the storage rack 100 includes uprights 110, crossbeams 130, and longitudinal beams 120. There are four uprights 110, four crossbeams 130, and four longitudinal beams 120. The four uprights 110 are vertically arranged. Along the horizontal direction, two crossbeams 130 are connected between two adjacent uprights 110. Along the longitudinal direction, two longitudinal beams 120 are connected between two adjacent uprights 110. The bottom of the four longitudinal beams 120 is fixed to the ground by expansion bolts.

[0041] There are four receiving frames 140. The receiving frames 140 are set vertically along the height direction of the column 110. Two receiving frames 140 are installed between two adjacent crossbeams 130. The two receiving frames 140 are arranged at intervals along the length direction of the crossbeam 130. Therefore, there are four receiving frames 140 on the storage rack 100. The receiving platforms 141 on each receiving frame 140 are aligned one by one. There are four legs on the vehicle platform 001. The four legs on each vehicle platform 001 rest on the same layer of receiving platform 141 of the four receiving frames 140 respectively.

[0042] The lifting device 300 is a hydraulic lifting device, and the lifting device 300 is located at the bottom of the storage rack 100.

[0043] In some embodiments, the first lateral movement mechanism 400 includes a transfer frame 410, a transfer frame drive device 420, and a transfer frame transmission device 430. The transfer frame 410 is slidably mounted on the lifting movable end of the lifting device 300, the transfer frame drive device 420 is fixedly mounted on the lifting movable end of the lifting device 300, one end of the transfer frame transmission device 430 is mounted on the power output end of the transfer frame drive device 420, and the other end of the transfer frame transmission device 430 is mounted on the transfer frame 410. The transfer frame drive device 420 drives the transfer frame 410 to move laterally on the lifting movable end of the lifting device 300 through the transfer frame transmission device 430.

[0044] Specifically, the transfer frame 410 is a rectangular flat frame structure. The transfer frame 410 is located in the middle of the lifting movable end of the lifting device 300. The four corners of the transfer frame 410 are provided with positioning cones 411. When the lifting device 300 drives the transfer frame 410 to receive the vehicle platform 001, the positioning cones 411 will pass through the positioning holes on the vehicle platform 001. The positioning cones 411 can play a positioning role to prevent the vehicle platform 001 from sliding laterally on the transfer frame 410. The middle of the transfer frame 410 is provided with a crossbar 412. The transfer frame drive device 420 is a motor. The transfer frame drive device 420 is fixed to the lifting movable end of the lifting device 300. The transfer frame transmission device 430 includes a lead screw and a lead nut. The lead nut is fixed in the middle of the crossbar 412. One end of the lead screw is installed at the power output end of the transfer frame drive device 420, and the other end of the lead screw is connected to the lead nut.

[0045] After the lifting device 300 lifts the transfer frame 410 and aligns it with the vehicle platform 001, the transfer frame drive device 420 drives the lead screw to rotate. The rotation of the lead screw and lead nut will cause the transfer frame 410 to move horizontally. The transfer frame 410 will cause the vehicle platform 001 to move horizontally, so that the legs of the vehicle platform 001 are misaligned with the receiving platform 141. Then the lifting device 300 lowers to remove the vehicle platform 001 from the storage rack 100.

[0046] In order to ensure that the transfer frame 410 moves smoothly on the lifting device 300, in some embodiments, the lifting movable end of the lifting device 300 is equipped with a slide rail 201, and the transfer frame 410 is provided with a slider 413, which is slidably mounted on the slide rail 201.

[0047] Specifically, the lifting device 300 has four slide rails 201 at its lifting movable end. The slide rails 201 extend along the length of the vehicle platform 001. The four corners of the shift frame 410 have four sliders 413. The four sliders 413 on the shift frame 410 are slidably mounted on the four slide rails 201. The shift frame drive device 420 slides horizontally along the slide rails 201 through the shift frame transmission device 430, so that the vehicle platform 001 moves along the length of the crossbeam 130 to offset the legs on the vehicle platform 001 from the receiving platform 141.

[0048] In some embodiments, the second lateral movement mechanism 500 includes two lateral movement arm assemblies 510 disposed opposite each other and a lateral movement arm assembly drive device 520 disposed between the two lateral movement arm assemblies 510. The lateral movement arm assembly drive device 520 and each lateral movement arm assembly 510 are connected by a lateral movement arm assembly transmission device 530.

[0049] Specifically, two lateral arm assemblies 510 are provided, located at both ends of the bottom of the storage rack 100 along the length of the crossbeam 130. The main structure of the lateral arm assembly 510 is a channel steel structure, extending along the length of the longitudinal beam 120. The transmission device 530 of the lateral arm assembly includes a gear 531, a rack 532, and a transmission rod 533. The rack 532 is fixed to the inner side of the lateral arm assembly 510. The gear 531 meshes with the rack 532 and is connected to the transmission rod 533. The drive device 520 of the lateral arm assembly includes a motor. One end of the transmission rod 533 is connected to the power output end of the drive device 520, and the other end of the transmission rod 533 is connected to the gear 531. In a fixed connection, during operation, the lateral arm assembly drive device 520 drives the transmission rod 533 to rotate, which in turn drives the gear 531 to rotate. The rotation of the gear 531 meshes with the rack 532, causing it to move back and forth. The rack 532 then drives the lateral arm assembly 510 to move forward or backward, thereby enabling the lateral arm assembly 510 to extend or retract at the bottom of the storage rack 100. When the lifting device 300 descends and places the vehicle platform 001 onto the two lateral arm assemblies 510, the lateral arm assembly drive device 520, through the meshing of the gear 531 and rack 532, causes the lateral arm assembly 510 to carry the vehicle platform 001 out, thereby transferring the vehicle platform 001 on the lateral arm assembly 510 to the pallet seat 200.

[0050] To ensure that the lateral arm assembly 510 remains stable when extending or retracting at the bottom of the storage rack 100, in some embodiments, the vehicle platform storage device further includes a guide device 600. The guide device 600 includes a base plate 610 and a plurality of roller groups 620 disposed on the base plate 610. The base plate 610 is disposed below the storage rack 100 and extends along the lateral direction of the second lateral movement mechanism 500. The roller groups 620 are spaced apart along the length direction of the base plate 610. The lateral arm assembly 510 is provided with a guide plate 514, which is embedded between the roller groups 620. The roller groups 620 are supported at the bottom of the lateral arm assembly 510.

[0051] Specifically, there are two guide devices 600, corresponding to two transverse arm assemblies 510 respectively. Both guide devices 600 are located on both sides below the storage rack 100. The base plate 610 can be a long strip structure. The base plate 610 extends along the length of the longitudinal beam 120 and is fixed to the ground below the storage rack 100 by expansion bolts. Alternatively, there can be multiple base plates 610, each with a roller assembly 620 installed on it. The base plates 610 are arranged at intervals along the length of the longitudinal beam 120 and fixed to the ground below the storage rack 100 by expansion bolts.

[0052] Each roller assembly 620 includes two rollers and two roller mounting seats. The two roller mounting seats are spaced apart along the width direction of the base plate 610. One roller is rotatably mounted on each roller mounting seat. Therefore, a roller gap is formed between the two rollers on each roller assembly 620 in the width direction of the base plate 610. The bottom of the transverse arm assembly 510 is provided with an elongated guide plate 514 extending along the length direction of the transverse arm assembly 510. The guide plate 514 is embedded in the roller gap of each roller assembly 620. At the same time, the roller surface of each roller assembly 620 is supported on the bottom of the transverse arm assembly 510.

[0053] During operation, the transverse arm assembly 510 moves on each roller group 620, and at the same time, the transverse arm assembly 510 drives each roller group 620 to roll, thereby effectively reducing the moving resistance of the transverse arm assembly 510 and making the movement of the transverse arm assembly 510 smoother. Moreover, the guide plate 514 of the transverse arm assembly 510 is embedded in the roller gap of the roller group 620. Therefore, during the movement of the transverse arm assembly 510, the guide plate 514 will be constrained in the roller gap of each roller group 620, thereby ensuring that the transverse arm assembly 510 maintains linear movement and stable movement during transverse movement.

[0054] Furthermore, in some other embodiments, the end of the lateral arm assembly 510 is provided with a wheel 515. When the lateral arm assembly 510 extends from the bottom of the access rack 100, the wheel 515 will contact the ground. As the lateral arm assembly 510 moves, the wheel 515 will also support the ground and roll. This makes the extension or retraction of the lateral arm assembly 510 smoother, and the wheel 515 also supports the lateral arm assembly 510, ensuring better stability of the lateral arm assembly 510 during extension.

[0055] In some embodiments, the transverse arm assembly 510 is provided with a conveying arm assembly 700, which includes an arm plate 710, a drive sprocket, a driven sprocket 720, a chain 740, and a sprocket drive device 750. The drive sprocket and the driven sprocket 720 are both mounted on the arm plate 710. The chain 740 is wrapped around the arm plate 710 and meshes with the drive sprocket and the driven sprocket 720. The sprocket drive device 750 is mounted on the arm plate 710, and the drive sprocket is mounted on the power output end of the sprocket drive device 750.

[0056] Specifically, the arm plate 710 is a long strip-shaped plate structure. One end of the arm plate 710 is equipped with a drive sprocket, and the other end of the arm plate 710 is equipped with a driven sprocket 720. The chain 740 wraps around the outside of the arm plate 710 along the length direction and meshes with the drive sprocket and the driven sprocket 720. The sprocket drive device 750 is a motor and is fixed to one side of the arm plate 710. The drive sprocket is installed at the power output end of the sprocket drive device 750.

[0057] During operation, the lifting device 300 moves the vehicle platform 001 downward, placing it onto the conveyor arm assembly 700. Simultaneously, the vehicle platform 001 presses against the chain 740. The lateral arm assembly 510 moves the vehicle platform 001 from under the storage rack 100 onto the conveyor arm assembly 700. Then, the sprocket drive device 750 drives the drive sprocket to rotate, causing the drive sprocket to drive the chain 740. Through the transmission of the chain 740, the vehicle platform 001 is transferred from the conveyor arm assembly 700 to the pallet seat 200.

[0058] In some embodiments, the conveying arm assembly 700 is disposed above the transverse arm assembly 510, and a lifting device 800 is provided between the conveying arm assembly 700 and the transverse arm assembly 510.

[0059] After the transverse arm assembly 510 moves the vehicle plate 001 on the conveyor arm assembly 700 out from under the storage rack 100, the lifting device 800 will lift and lower it so that the vehicle plate 001 on the conveyor arm assembly 700 is flush with the pallet seat 200. Then, the vehicle plate 001 is transferred to the pallet seat 200 through the chain 740 on the conveyor arm assembly 700. This allows the height of the conveyor arm assembly 700 to be adjusted at any time to ensure that the vehicle plate 001 can be transferred accurately.

[0060] In some embodiments, the lifting device 800 includes a linkage mechanism 810, a linkage mechanism drive device 820, and a linkage mechanism transmission device. One end of the linkage mechanism 810 is rotatably connected to the transverse arm assembly 510, and the other end of the linkage mechanism 810 is rotatably connected to the conveying arm assembly 700. The linkage mechanism transmission device is installed at the power output end of the linkage mechanism drive device 820 and is connected to the linkage mechanism 810 in a transmission manner. The linkage mechanism drive device 820 drives the linkage mechanism 810 to extend or fold through the linkage mechanism transmission device.

[0061] The linkage mechanism 810 includes four sets of linkages, each set of linkages includes two rotatably connected rods, and the two ends of each set of linkages are rotatably connected to the transverse arm assembly 510 and the conveying arm assembly 700, respectively.

[0062] Specifically, the linkage mechanism 810 includes four sets of links, namely the first link 811, the second link, the third link 812, and the fourth link 813. The first link 811 and the second link are aligned and spaced apart along the width direction of the transverse arm assembly 510, and the third link 812 and the fourth link 813 are aligned and spaced apart along the width direction of the transverse arm assembly 510. The first link 811 and the second link are aligned with the third link 812 and the fourth link 813 along the length direction of the transverse arm assembly 510, and the first link 811 and the second link have the same folding direction, and the third link 812 and the fourth link 813 have the same folding direction.

[0063] The linkage mechanism drive device 820 is a motor. The linkage mechanism transmission device includes a lead screw and a lead screw nut. A sleeve is provided between the first link 811 and the second link, connecting the rotation points of the first link 811 and the second link. A lead screw nut is provided between the third link 812 and the fourth link 813, connecting the rotation points of the third link 812 and the fourth link 813. The lead screw nut and the sleeve are aligned with each other. The lead screw passes through the sleeve and engages with the lead screw nut. The linkage mechanism drive device 820 is mounted on the first link via a connecting plate. Between the first link 811 and the second link, the linkage mechanism drive device 820 can drive the lead screw to rotate. The rotation of the lead screw will cause the lead screw nut to move along the lead screw. The movement of the lead screw nut will cause the third link 812 and the fourth link 813 to fold or extend. Since the linkage mechanism drive device 820 is installed between the first link 811 and the second link, when the third link 812 and the fourth link 813 fold or extend, the first link 811 and the second link will also extend or extend accordingly, thereby achieving the lifting effect.

[0064] To ensure stable lifting of the conveyor arm assembly 700, in some embodiments, two linkage mechanisms 810 are provided between the transverse arm assembly 510 and the conveyor arm assembly 700, and the two linkage mechanisms 810 have the same structure.

[0065] Specifically, two linkage mechanisms 810 are arranged one in front of the other along the length of the transverse arm assembly 510. The linkage mechanism drive device 820 is installed between the first link 811 and the second link of the rear linkage mechanism 810. The lead screw passes through the sleeve of the rear linkage mechanism 810 and cooperates with the lead screw nut of the rear linkage mechanism 810. At the same time, the lead screw also passes through the sleeve of the front linkage mechanism 810 and cooperates with the lead screw nut of the front linkage mechanism 810. In this way, the two linkage mechanisms 810 share the same lead screw to ensure synchronization during the lifting process.

[0066] Of course, this application is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
