Description

Technical Field

[0001] This invention relates to the field of automated parking systems, and particularly to a multi-level automated parking system and storage / retrieval method with a novel balancing rotating frame. Background Technology

[0002] Traditional simple multi-level parking racks are either structurally complex, have high manufacturing costs per parking space, or require vehicles to drive out of the parking space from the lower level when storing vehicles on the upper level, making it very inconvenient for vehicles to enter and exit. Summary of the Invention

[0003] To address one or more of the above problems, the present invention provides a multi-level parking system with a novel balancing rotating frame and a method for storing and retrieving the system.

[0004] According to one aspect of the present invention, a multi-level parking system with a novel balancing rotating frame is provided, suitable for parking cars on two or more levels. The parking system includes a base, at least one layer of balancing rotating frames, a transporter, an intelligent control system, and temporary parking frames drawn on the ground perpendicular to the entrances and exits of two adjacent longitudinal ground parking spaces. The base is placed at the center of the line between two adjacent longitudinal ground parking spaces. Multiple balancing rotating frames mounted on the base can rotate 90° clockwise or counterclockwise, thereby driving parking baskets symmetrically mounted on both sides of the top of the balancing rotating frames to rotate 90° clockwise or counterclockwise horizontally. The intelligent control system automatically manipulates the transporter with lateral movement and lifting functions using a control program to transport cars parked in the temporary parking frames to parking baskets on any level, or to transport vehicles stored in parking baskets to the temporary parking frames.

[0005] In some embodiments, the base includes: a base plate, a positioning column, a center plate, a positioning ring, and a protective frame. The positioning column has a tubular structure, and its outer diameter is smaller than the distance between two longitudinally parked vehicles on the same level. The balancing rotating frame includes: a rotating column, a central bearing, circumferential rollers, cantilever beams, a rotating motor, a drive gear, a driven gear ring, and a parking basket. Two cantilever beams extending laterally on both sides are installed on the top of the positioning column. The output shaft of the rotating motor is equipped with a drive gear. The rotating motor is installed on the outer wall of the positioning column. The driven gear ring is fitted on the outer circumference of the middle section of the rotating column, so that the drive gear and the driven gear... The moving gear ring engages, thereby rotating the motor to drive the rotating column and cantilever beam to rotate 90° clockwise or counterclockwise. Under the cantilever beam, two parking baskets are symmetrically hoisted to provide weight balance. The cavity inside each parking basket can hold one car. The bottom of the outer side of the parking basket has an opening. The front and rear tires of the car are placed on the tire support plates at both ends of the basket. When not in use for parking or retrieving, the two parking baskets are located directly above two adjacent longitudinal parking spaces on the ground floor. The lowest height of their bottom is greater than the height of the vehicles stored on the ground floor, so as not to obstruct the parking of vehicles in the two adjacent longitudinal parking spaces on the ground floor.

[0006] In some implementations, when transporting or retrieving vehicles, two support methods are used: supporting the vehicle chassis or supporting the front and rear wheels of the vehicle. These two methods are used alternately without interference to transfer and hand over the vehicles.

[0007] In some embodiments, the transporter includes a lateral displacement device and a lifter, the minimum height of the transporter being lower than the minimum ground clearance of the vehicle chassis, and the initial horizontal width of the support platform for the vehicle chassis being less than the distance between two parking spaces on the ground floor, and the length being slightly greater than the width of the vehicle chassis.

[0008] In some implementations, the base plate is cross-shaped, with the outwardly extending portion serving as the lateral track for the inner traveling rollers of the lifting mechanism of the transporter.

[0009] In some embodiments, the transporter includes a lifter, which includes a lifting device. The lifting device includes a long side base, a long-arm scissor mechanism, a short side platform, a telescopic short arm, grooved rollers, and a fixed support. The length of the scissor arm of the long-arm scissor mechanism is less than the length of the side beam of the long side base but greater than the length of the side beam of the short side platform. Both side beams of the long side base and the short side platform have a fixed support at one end and a grooved track at the other end. The hinged ends of the upper and lower fixed arms of the long-arm scissor mechanism are respectively hinged to the fixed supports on the short side platform and the long side base via pins. The sliding arm end below the long-arm scissor mechanism is equipped with grooved rollers located in the grooved track. The sliding arm end above the long-arm scissor mechanism is each equipped with a shortened arm via pins. The telescopic short arm is equipped with at least two grooved rollers that can be embedded in the grooved track of the short side platform along its axial direction.

[0010] In some embodiments, a chassis support mechanism is installed at the top of the lifting device. The chassis support mechanism includes: an extension motor, a transmission chain, a telescopic screw, a left-hand nut, a right-hand nut, horizontal swing arms, support beams, limit contact plates, and rubber pads. The left-hand and right-hand nuts, symmetrically screwed onto the telescopic screw, are hinged to the four horizontal swing arms and two support beams to form a symmetrical double "V"-shaped extension linkage mechanism. The length of the support beams is adapted to the vehicle width. Rubber pads are attached to the upper surfaces of both ends of the support beams. A limit contact plate is installed on each of the four corners. When the left-hand and right-hand nuts are close to the middle of the telescopic screw, the two support beams... When the beams are closest to each other, and the left-hand and right-hand nuts are close to the ends of the telescopic screw, the two support beams are furthest apart. The width of the two side edges reaches the width of the front and rear support points of the vehicle chassis. A travel contact switch is installed at the rear end of the limit contact plate. When the chassis support device is "expanding" under the vehicle chassis, once the limit contact plate touches the vehicle tire, it will trigger the travel contact switch installed at the rear end of the limit contact plate to retract, which will cut off the power supply to the expansion motor and stop the chassis support mechanism from "expanding". The four rubber pads are exactly aligned with the four support force points of the vehicle chassis above, thereby avoiding damage to the vehicle chassis during the lifting process. Alternatively, the limit contact plate can be replaced with a diffuse reflection photoelectric switch.

[0011] In some implementations, two sets of balanced, two-tiered, planar parking pallets can be symmetrically mounted on both sides of the top of the rotating frame on the base.

[0012] In some embodiments, the traveling rollers installed at the front of the long side base of the lifting device adopt a telescopic design to increase the stability of the lifting device during lifting and lateral vehicle movement. The traveling roller telescopic device includes: a through piston rod, a sliding cylinder, a sliding support, and a piston rod support. The through piston rod is horizontally mounted on the front beam of the long side base through the piston rod support. A sliding support is installed on each of the two side beams of the coaxial long side base. The sliding cylinders that are matched at both ends of the through piston rod are symmetrically fitted into the sliding supports. A traveling roller is installed at the bottom end of each of the two sliding cylinders. Therefore, by supplying hydraulic oil to the oil port of the middle through piston rod or to the two sliding cylinders, the two sliding cylinders can extend or retract to the sides, thereby driving the two traveling rollers to extend or retract to the sides, increasing the bearing surface on the ground when the lifting device transports vehicles.

[0013] A method for storing and retrieving a vehicle using the above-described parking system, wherein in the initial state, the lift is lowered to its lowest position and the lateral movement device is at its innermost position, the specific storage and retrieval method is as follows: When parking / retrieving a vehicle in one of the two parking spaces on the ground floor, the vehicle can be driven directly into / out of the parking space; When storing a vehicle in the parking basket: S1-1, first park the vehicle in the temporary parking frame, adjust the angle of the parking basket to reach the vehicle receiving position, and at the same time, the lateral movement device of the transporter pushes the chassis support mechanism on the lift to insert under the chassis of the car parked in the temporary parking frame; S1-2, the lift rises, raising the car to a position where the lowest point of the tires is slightly higher than the upper surface of the two tire support plates of the parking basket, and then the lateral movement device retracts the lift and the vehicle, pushing the vehicle into the empty parking basket; S1-3, the lift descends, and during the descent, the front and rear tires of the vehicle are supported by the tire support plates of the parking basket and remain there, and the lift continues to descend to the lowest position, i.e., the initial position; When retrieving a vehicle from the parking basket: S2-1, the balancing rotating frame containing the vehicle rotates so that the parking basket containing the vehicle is directly above the transporter; S2-2, the lifter raises the vehicle against the chassis support mechanism until the front and rear tires of the vehicle leave the tire support plate of the parking basket; S2-3, the lateral movement device pushes the lifter and the vehicle into the upper part of the temporary parking frame; S2-4, the lifter lowers to the lowest position, at which point the chassis support mechanism disengages from the vehicle chassis; S2-5, the lateral movement device retracts the lifter to the innermost side, returning it to the initial position.

[0014] In some implementations, before raising the lifter in step S1-2, the chassis support mechanism is first deployed so that the two support beams are directly below the vehicle chassis support point. In step S1-3, before the lifter continues to descend to the lowest position, the chassis support mechanism is first retracted so that the two support beams are retracted back into the plane of the lifter.

[0015] In some implementations, step S2-2 specifically involves: first, raising the lifter against the chassis support mechanism to a position close to the vehicle chassis; then, unfolding the chassis support mechanism so that the two support beams are aligned with the vehicle chassis support points; controlling the lifter to continue rising until the vehicle tires leave the tire tray of the storage basket; in step S2-4, after the lifter descends to the point where the chassis support mechanism is detached from the vehicle chassis, first retracting the chassis support mechanism so that the two support beams retract into the plane of the lifter.

Detailed Implementation

[0017] The invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a multi-level parking system with a novel balancing rotating frame is suitable for parking cars on two or more levels. It includes a base 1, at least one balancing rotating frame 2, a transporter 3, an intelligent control system 4, and temporary parking frames 01 vertically drawn on the ground at the entrances and exits of two adjacent longitudinal parking spaces. The base 1 is fixed at the center of the line between the two adjacent longitudinal parking spaces. Multiple balancing rotating frames 2 mounted on the base 1 can rotate 90° clockwise or counterclockwise to the left or right, causing the two-story-high parking baskets 28, symmetrically mounted on both sides of the top of the balancing rotating frames 2, to rotate 90° horizontally to the left or right. The intelligent control system 4 uses an automatic control program to operate the transporter 3, which has lateral movement and lifting functions, to "automatically transport" vehicles parked in the temporary parking frames 01 to a parking basket 28, and vice versa. Its beneficial effects are: applicable to two adjacent longitudinal ground parking spaces, and automatic intelligent three-dimensional parking for multi-story cars with two or more floors. It does not change the original way of vehicles freely entering and exiting the longitudinal ground parking spaces, nor does it occupy other ground space. It effectively utilizes the space above the ground parking spaces. The invention is simple to manufacture, convenient and quick to install on site, intelligent and automatic vehicle storage and retrieval, faster speed, safer operation, convenient, fast and accurate vehicle entry and exit before and after storage and retrieval, short vehicle storage and retrieval time, and safe entry and exit for drivers and personnel.

[0019] Preferably, the base 1 includes: a base plate 11, a positioning column 12, a center plate 13, a positioning ring 14, and a protective frame 15. The tubular positioning column 12, whose cross-sectional lateral outer dimension is smaller than the distance between two parked vehicles on the first floor, is vertically welded to the base plate 11. After the tubular positioning column 12 is vertically positioned at the center of the centerline between the two longitudinal parking spaces on the ground, the cross-shaped steel plate base plate 11 is fixed to the ground. The center plate 13 is horizontally welded to the lower section of the positioning column 12, and the lower section has a through hole for support. The positioning ring 14 is fitted onto the top section of the positioning column 12. Two protective frames 15 are symmetrically installed laterally on both sides of the positioning column 12 below the positioning ring 14. This serves as both a height limit frame for vehicles in the first-floor parking spaces and a protection frame to prevent the first-floor drivers and second-floor vehicles from falling.

[0020] Preferably, the balancing rotating frame 2 includes: a rotating column 21, a central bearing 22, circumferential rollers 23, a cantilever beam 24, a rotating motor 25, a driving gear 26, a driven gear ring 27, and a storage basket 28. The central bearing 22, which uses a heavy-duty tapered bearing, is installed in the central bearing ring below the bottom end plate 29 of the rotating column 21 and is vertically inserted into the positioning column 12. This central bearing 22 fits precisely on the central step of the central plate 13. Several circumferential rollers 23 are vertically installed on the periphery of the middle part of the positioning column 12, so that the outer circumference of the rollers presses against the outer circumferential surface of the positioning ring 14, and can roll circumferentially along this surface. The rotating column 21 is positioned by the central bearing 22, which in turn forms a pivot to overcome its weight and torque. Two cantilever beams 24 extending laterally on both sides are mounted on the top of the positioning column 12. The drive gear 26 is mounted on the output shaft of the rotating motor 25. The driven gear ring 27 is fitted on the outer circumference of the upper section of the rotating column 21. The rotating motor 25 of the second layer is vertically fixed to the outer wall of the positioning column 12, or the rotating motor of the upper layer is mounted on the upper section of the rotating column of the lower layer, so that the drive gear 26 meshes with the driven gear ring 27, thereby driving the balance rotating frame 2 to rotate vertically 90° to the left or right.

[0021] Preferably, the parking basket 28 includes: a C-shaped frame 281, a D-shaped frame 282, and two tire support plates 283, which are welded together to form a parking frame-type basket with an opening on one side of the bottom. The cavity inside the parking basket 28 can hold a small car, and the front and rear tires of the car are exactly pressed within the range of the support plates 283 at both ends. The bottom openings of the two parking baskets 28 face outwards, and they are symmetrically installed below the transverse cantilever extension of the cantilever beam 24. Its advantages are: the base basically does not require civil engineering and can be placed directly on the ground; the cross-shaped steel plate base saves materials and counteracts the 360° horizontal rotation torque when the upper layer of the balancing rotating frame is unbalanced; the power of the balancing rotating frame solves the planar movement function of the two parking spaces on the upper layer and also plays a role in balancing the load on both sides; the parking basket with an opening in the middle at the top provides an insertion port for the vehicle to be inserted laterally into the cavity, and the method of hoisting the parking basket also increases the horizontal automatic stability.

[0022] Preferably, the transporter 3 includes a lateral shifting device 31 and a lifting device 32. When the lifting device 32 is in its lowest position, its height is lower than the minimum ground clearance of the vehicle, its horizontal width is smaller than the distance between two cars in two parking spaces on the ground floor, and its length is approximately equal to the width of the vehicle chassis. Therefore, the transporter 3 can be placed between two vehicles parked longitudinally on the ground floor without affecting their entry and exit. Furthermore, the lateral shifting device 31 can push the lifting device 32 to move it, inserting it under the chassis of the vehicle parked in the temporary parking frame 01, then supporting the vehicle chassis and lifting the vehicle. Preferably, the lateral displacement device 31 includes: a lateral displacement cylinder 311 and a lateral displacement support 312. The lateral displacement support 312 is installed at the longitudinal centerline of the base plate 11 of the positioning column 12. The lateral displacement cylinder 311 is placed horizontally and longitudinally through a hole in the lower section of the positioning column 12. The cylinder barrel of the lateral displacement cylinder 311 is installed on the lateral displacement support 312, and the piston rod is connected to the bottom of the lifting device 32. Preferably, the lifting device 32 includes: a traveling roller 321, a hydraulic station 322, a lifting cylinder 323, and a lifting device 50. The lifting cylinder 323 and the side-shifting cylinder 311 share a hydraulic station 322. The beneficial effect is that the transporter adopts a hydraulic station, which can provide power to both the side-shifting device and the lifting device at the same time, greatly simplifying the equipment structure and reducing manufacturing costs.

[0023] like Figure 4As shown, the lifting device 50 is a scissor-type hydraulic lifting platform that adopts ultra-low minimum height and high lifting structure technology. The lifting device 50 includes: a long side base frame 51, a long arm scissor mechanism 52, a short side platform 53, a telescopic short arm 54, grooved rollers 55, and fixed supports 56. The length of the scissor arm of the long arm scissor mechanism 52 is less than the length of the side beam of the long side base frame 51, but greater than the length of the side beam of the short side platform 53. Under normal circumstances, each of the two side beams of the long side base frame 51 and the short side platform 53 has a fixed support 56 at one end and a grooved track at the other end. The hinged ends of the upper and lower fixed arms of the long arm scissor mechanism 52 are respectively hinged to the fixed supports on the short side platform 53 and the long side base frame 51 through axle pins. At the other end of the long arm scissor mechanism 52, two sliding arms are each equipped with a grooved roller 55, which is placed in the grooved track of the long side base frame 51. At the other end of the long arm scissor mechanism 52, two sliding arms are respectively equipped with a grooved roller 55. Each telescopic short arm 54 is mounted horizontally via a pivot pin. At least two grooved rollers 55 are installed on each telescopic short arm 54 in a straight horizontal line. These grooved rollers 55 are all fitted into the grooved track of the short side platform 53. When the short side platform 53 is at its lowest position, a section of the telescopic short arm 54 will extend beyond the end of the grooved track of the short side platform 53 at its longest point, while ensuring that the two grooved rollers 55 do not slip out of the grooved track of the short side platform 53. When the scissor lift is at its highest point, the telescopic boom 54 retracts into the grooved track of the short side platform 53, achieving a lifting height greater than the length of the platform using a single-fork scissor lift. Four traveling rollers 321 are installed at the four corners of the long side base frame 51. The hydraulic station 322 is installed on the base plate 11. The oil cylinder end of the lifting cylinder 323 is hinged to the long side base frame 51, and the piston rod end is hinged to a support in the middle section of one of the booms of the long boom scissor lift mechanism 52. The advantages of using a long-arm scissor lift mechanism are: compared with traditional scissor lift mechanisms, with the same number of scissor lift mechanisms, it can achieve an ultra-high maximum lifting height with an ultra-low minimum height, which is suitable for situations where the height of the vehicle is lower than the width of the vehicle and the ground clearance of the vehicle is relatively small. The method of supporting the vehicle chassis also creates the preconditions for automatically picking up vehicles from the ground.

[0024] like Figure 5 , Figure 6As shown, to accurately locate the vehicle chassis support point, a chassis support mechanism 60 can be installed at the top of the lifting device 50. The chassis support mechanism 60 includes: an extension motor 61, a transmission chain 62, a telescopic screw 63, a left-hand nut 64, a right-hand nut 65, a horizontal swing arm 66, a support beam 67, a limit contact plate 68, and a rubber pad 69. The telescopic screw 63 is a screw with a driven sprocket in the middle and left and right threads at both ends. Both ends are longitudinally and horizontally mounted in the center of the short side platform 53 via bearings. An extension motor 61 with a drive sprocket on its extension shaft is installed parallel to the short side platform 53. The drive sprocket and the driven sprocket are connected by the transmission chain 62. The left-hand nut 64 and the right-hand nut 65 are symmetrically screwed onto the telescopic screw 63. The left-hand nut 64, the right-hand nut 65, the four horizontal swing arms 66, and the two support beams 67 are hinged together by vertical pins to form a horizontal double-symmetrical "V"-shaped extension linkage mechanism. The length of support beam 67 is equal to the width of the vehicle. A rubber pad 69 is attached to the upper surface of each end of support beam 67, and a limit contact plate 68 is installed on each side of each end. When the left-hand nut 64 and right-hand nut 65 are close to the middle of the telescopic screw 63, the two support beams 67 are closest together; when the left-hand nut 64 and right-hand nut 65 are close to the ends of the telescopic screw 63, the two support beams 67 are furthest apart. The width of the side edges reaches the width of the front and rear support points of the vehicle chassis. A travel contact switch is installed at the rear end of the limit contact plate 68. When the chassis support device is "expanding" under the vehicle chassis, if the limit contact plate 68 touches the vehicle tire, it triggers the travel contact switch at the rear end of the limit contact plate 68 to retract, cutting off the power to the expansion motor 61. The chassis support mechanism 60 stops "expanding," and the four rubber pads 69 are precisely aligned with the four support force points of the vehicle chassis above, thus preventing damage to the vehicle chassis during lifting. The limit contact plate 68 can be replaced with a reflective photoelectric switch.

[0025] The advantages of the extended chassis support mechanism are: with a smaller lifting device, it can reach the chassis support with an automatically adjustable width, which can not only align with the support points of various brands of vehicle chassis, thus expanding the support area, but also avoid damaging the vehicle chassis or tires, making vehicle transportation more stable.

[0026] The temporary parking frame 01 includes a dashed frame 02 and a front wheel stop line 03. The dashed frame 02 is a white dashed frame drawn on the ground perpendicular to the entrances and exits of two adjacent parking spaces on the first floor. The size of the dashed frame 02 is slightly larger than the planar projection size of the vehicle. The front wheel stop line 03 is two horizontal double dashed lines drawn within the dashed frame 02, serving as the front wheel stop lines for vehicles coming from both directions. Vehicles must first be parked within the dashed frame 02, and the front wheels of the vehicle must stop within the double dashed lines of the front wheel stop line 03. The projection of any part of the vehicle on the ground must not exceed the dashed frame 02; otherwise, the transporter 3 cannot be started.

[0027] Setting up temporary parking frames on the ground, including dashed frames and front wheel stop lines, has the following benefits: it allows the transporter to accurately align with the vehicle chassis and safely retrieve the vehicle, and enables the vehicle to be safely inserted into the parking basket without collision, with the front and rear tires of the vehicle accurately landing on the tire trays of the parking basket.

[0028] The intelligent control system 4 includes: an electrical control box 41, a parking position recognition device 42, an operation panel 43, a PLC automatic control device 44, a fault alarm device 45, and other conventional electrical components. The electrical control box 41 is installed on the base 1 in a position convenient for the driver to operate. The operation panel 43, the PLC automatic control device 44, and the fault alarm device 45 are all installed on the electrical control box 41. The parking position recognition device 42 is installed on the frame of the temporary parking frame 01. When the driver operates the operation panel 43, the parking position recognition device 42 can emit wireless rays to detect whether the vehicle parts parked in the temporary parking frame 01 are outside the frame.

[0029] The beneficial effects are: this multi-level parking system with a novel balanced rotating frame can intelligently, automatically, and safely complete vehicle storage and retrieval in terms of identification, programmed operation in various states, fault detection, and alarm response, making the multi-level parking system faster and safer to operate. In this implementation, the two parking baskets 28 on each floor are directly above the parking spaces on the ground floor, which is the initial position of the balance rotating frame 2 on each floor. The elevator 32 is at its lowest point and the lateral shifting device 31 is at its innermost position, which is the initial position of the transporter 3. When parking in the two longitudinal parking spaces on the ground floor, vehicles can turn directly into or out of the two ground parking spaces perpendicular to the walkway. However, the projection of vehicles parked on the ground must not be inside the temporary parking frame 01. like Figure 7 , Figure 8 As shown, the two-level parking system of the present invention is the most common embodiment. For a two-level parking system based on a balancing rotating frame and a transporter, suitable for two-level parking of cars, it includes a base 1, a balancing rotating frame 2, a two-level transporter 30, a two-level intelligent control system 40, and temporary parking frames 01 vertically drawn on the ground at the entrances and exits of two adjacent longitudinal parking spaces. The two-level transporter 30 includes: a lateral movement device 31 and a single-stage lifter 320. The single-stage lifter 500 is a single-stage scissor-fork hydraulic lift platform using ultra-low minimum height and high lifting structure technology. The single-stage lifter 500 includes: a long-side base frame 51, a single-stage long-arm scissor-fork mechanism 520, a short-side platform 53, a telescopic short arm 54, and in-slot rollers 55. The specific working process of the two-level automated parking system is as follows: When parking a vehicle on the second level: First, park the vehicle in the temporary parking frame 01, ensuring the front wheels are within the double lines of the front wheel stop line 03. The driver and all other passengers should exit the vehicle. Next, press the "Storage" control button on the control panel 43. The fault alarm device 45 receives a wireless detection signal from the parking position identification device 42 and determines whether any vehicle parts extend beyond the temporary parking frame 01. If so, a correction voice alarm is issued, instructing the driver to adjust the vehicle to the correct parking position. The subsequent automatic program actions are as follows: The rotating motor 25 starts, driving the balance rotating frame 2 to rotate vertically by 90°, causing the unloaded parking basket 28 to rotate horizontally by 90° towards the second-level transporter 30. Simultaneously, the hydraulic station 322 of the second-level transporter 30 is activated, and the side-shifting device 31 linearly pushes the single-stage lifter 320 to insert under the car chassis parked in the temporary parking frame 01. The extension motor 61 of the chassis support mechanism 60 is activated, and the support beam 67 unfolds to reach the car chassis. Directly below the support point, the piston rod of the lifting cylinder 323 of the single-stage lifter 320 extends, and the single-stage lifter 320 rises, raising the car to a position slightly higher than the upper surface of the tire support plate 283 of the second-level parking basket 28. Then, the piston rod of the lateral shift cylinder 311 retracts, pushing the vehicle into the empty parking basket 28. At this time, the lateral shift device 31 also returns to its innermost initial position. Then, the piston rod of the lifting cylinder 323 retracts to its shortest position, and the vehicle descends so that the front and rear tires are supported on the tire support plate 283 of the parking basket 28 for storage. After that, the extension motor 61 of the chassis support mechanism 60 starts again, the support beam 67 retracts, and at the same time, the single-stage lifter 320 continues to descend to its lowest initial position. The second-level transporter 30 returns to its initial position. Finally, the rotating motor 25 starts in the opposite direction to drive the balance rotating frame 2 to rotate vertically by 90°, so that the parking basket 28, carrying the vehicle, rotates horizontally back 90° towards the initial position. The balance rotating frame 2 returns to its initial position, waiting for the next operation.

[0030] Conversely, when retrieving a vehicle from the second floor: the driver presses the "Retrieve" command key on the control panel 43 for the location where the vehicle needs to be retrieved. The subsequent automatic program actions are as follows: First, the rotating motor 25 starts, driving the balance rotating frame 2 to rotate vertically 90°. On the second-floor balance rotating frame 2, the parking basket 28 where the vehicle needs to be retrieved rotates horizontally 90° outwards. Simultaneously, the alarm installed on the lower outer corner of the parking basket 28 flashes a red light or adds a voice prompt, alerting the surrounding area: "The vehicle in the second-floor parking basket is starting to leave the garage; no personnel or vehicles are allowed to enter the temporary parking frame 01." At the same time, the hydraulic station 322 of the second-floor transporter 30 also starts. Simultaneously, the piston rod of the lifting cylinder 323 of the single-stage lifter 320 extends, and the single-stage lifter 320 rises against the chassis support mechanism 60. When it approaches the vehicle chassis, it pauses briefly, and then the chassis... The support mechanism 60 is activated, causing the support beam 67 to unfold and align with the support point of the vehicle chassis. The single-stage lifter 320 then rises until the front and rear tires of the vehicle leave the upper surface of the tire support plate 283 of the storage basket 28. Then, the lateral movement device 31 pushes the single-stage lifter 320 in a straight line, carrying the vehicle into the temporary parking frame 01. The piston rod of the lifting cylinder 323 retracts to its shortest position, and the single-stage lifter 320 reaches its lowest position. The support beam 67 detaches from the vehicle chassis. The extension motor 61 starts in reverse, causing the two support beams 67 to retract to their closest point. Then, the piston rod of the lateral movement cylinder 311 retracts, pulling the single-stage lifter 320 back to its innermost position. The second-layer transporter 30 returns to its initial position. At the same time, the rotation motor 25 starts in reverse, causing the drive balance rotating frame 2 to rotate vertically by 90°, causing the empty storage basket 28 to rotate horizontally back 90° towards its initial position. The balance rotating frame 2 returns to its initial position, waiting for the next operation.

[0031] like Figure 9 , Figure 10 As shown, in another embodiment of the new multi-level parking system with a rotating balance frame, two sets of balanced, two-tiered, planar parking trays 70 can be symmetrically installed on both sides of the top of the tray rotating column 20 on the base. The advantages are: the overall height of the two-tiered parking frame is lower, making it suitable for use in underground garages. At the same time, the foldable parking tray function of the parking frame makes it suitable for relocation at any time, or for folding down the parking tray when the two-tiered parking is not needed.

[0032] like Figure 11 As shown, the base plate 11 is made of a cross-shaped steel plate. The extended portions on all four sides not only increase resistance to the eccentric bending moment generated by parking only one vehicle on the second floor, but also extend further outwards. The two long sides of this extended portion are milled flat, serving as the lateral linear track 111 for the two inner traveling rollers 321 at the lower end of the lifting device 3. The two outer traveling rollers 321 run on the ground. This design has the advantage of making the lateral movement of the lifting device smoother and ensuring straight-line travel. Furthermore, such as Figure 12 , Figure 13 As shown, the traveling rollers 321 installed at the front of the long side base frame 51 in the lifting device 50 adopt a telescopic form to both sides, which increases the stability of the lifting device 50 during lifting and lateral vehicle movement. The traveling roller telescopic device 80 includes: a through piston rod 81, a sliding cylinder 82, a sliding support 83, and a piston rod support 84. The through piston rod 81 is horizontally mounted on the front beam of the long side base frame 51 through the piston rod support 84. A sliding support 83 is installed on each of the two side beams of the coaxial long side base frame 51. The sliding cylinders are fitted at both ends of the through piston rod 81. The cylinders 82 are symmetrically fitted inside the sliding support 83. Each of the two sliding cylinders 82 has a traveling roller 321 installed at its bottom end. Therefore, by supplying hydraulic oil to the central through piston rod 81 or to the oil ports on both sides of the sliding cylinders 82, the two sliding cylinders 82 can extend or retract to the sides, thereby driving the two traveling rollers 321 to extend or retract to the sides. The beneficial effect is that the lifting device increases the bearing area on the ground, thereby increasing the stability when transporting vehicles and preventing the raised vehicles from becoming unstable and falling due to longitudinal eccentric loading.

[0033] The specific working process of a multi-level parking system with a novel balancing rotating frame can be deduced similarly.

[0034] The above are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and all such modifications and improvements fall within the scope of protection of the present invention.
