Description

Technical Field

[0001] The invention relates to the field of traffic facilities and equipment, in particular to an annular multi-story three-dimensional parking garage. Background Art

[0002] As of the end of March 2022, the number of motor vehicles in my country reached 402 million, of which 307 million were cars, accounting for 76.37% of the total number of motor vehicles. Travel for Chinese people is becoming more and more convenient, but the increase in vehicle density and increasingly crowded cities have made parking more difficult. People are gradually feeling that it is easy to buy a car but difficult to use it.

[0003] A three-dimensional parking garage, whether it is a specially built parking building or an underground parking garage, is the best choice for parking more vehicles in a limited land area. At present, there are matrix parking garages and circular parking garages. Among them, the matrix parking garage is easy to build, and the more mature one is the suspended parking method. However, the matrix parking garage occupies a large area, and due to the limited number of entrances and exits, the vehicle transportation channel is single, and the efficiency of picking and placing vehicles is low; for the circular parking garage, it is just possible to park more vehicles in a smaller area. However, due to the imperfect design, the problem of low efficiency of picking and placing vehicles has not been solved.

[0004] In the invention application with patent application number 202011315544.9 and patent name "A Mechanical Stereoscopic Parking Garage", a multi-storey parking garage with a circular structure is provided, which can solve the problems of parking efficiency, parking space utilization and operation stability. However, the mechanical stereoscopic parking garage requires the driver to perform the task of vehicle operation by himself, does not solve the problem of automatic parking of vehicles, and does not adapt to the development trend of smart cities. The invention application with application number 202210317538.X and name "Underground Circular Multi-storey Intelligent Parking Garage" provides a circular multi-storey intelligent parking garage, including a column space located underground, a rotating frame with an upper part penetrating to the ground and capable of rotating is installed in the column space, and several layers of parking racks are arranged from bottom to top on the outer side of the rotating frame in the column space, and each parking rack is arranged with several parking spaces along the circumferential direction, and a lifting basket is arranged in the rotating frame for cars to drive in and carry cars to rise and fall along the rotating frame. This application provides a good smart parking garage solution, but the rotating frame can only transport one car at a time, and the efficiency of picking and placing cars is low. If more transport positions are added, the structure of the entire rotating frame will become very complicated, and the matching with other structures in the solution will also have to be significantly modified. The actual degree of automation is still not very high. Summary of the invention

[0038] The technical solution of the present invention and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0039] The annular multi-storey parking garage provided by the present invention is as follows: Figure 1 and Figure 2 As shown, it at least includes a lifting component 2000, a transport component 3000, a central column 4000, a controller and a cylindrical parking rack 1000. The lifting component 2000 and the transport component 3000 are used to transfer vehicles, transport vehicles from the entrance of the parking garage to the parking space, or take out the vehicles parked in the parking space and transport them to the exit of the parking garage (which can be the entrance at the same time). The overall structure of the parking rack 1000 is also set to a cylindrical shape, with multiple parking spaces in the middle. The central column 4000 supports the lifting component 2000, and the lifting component 2000 relies on the central column 4000 to reach different floors of the parking rack 1000. The annular multi-story three-dimensional parking garage of the present application can be set on the ground, and the bottom part of the parking garage can be set below the ground.

[0040] The controller is the control component of the annular multi-story parking garage of the present application. From the perspective of computer hardware, the controller is a processor. The processor can be a CPU (Central Processing Unit), a general-purpose processor, a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array) or other programmable logic devices, transistor logic devices, hardware components or any combination thereof. It can implement or execute various exemplary logic boxes, modules and circuits described in conjunction with the disclosure of the present invention. The processor can also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of DSP and microprocessors, etc. The controller is used to control the electronic components or sensors in the annular multi-story parking garage, and run related motors, valves or sensors, etc. according to the set instructions and programs.

[0041] The parking rack 1000 includes a plurality of annular parking racks 1100, a central column 4000 is coaxial with the central axis of the parking rack 1000, and a lifting assembly 2000 can be lifted and lowered on the central column 4000 and rotated around the central axis. Figure 2 As shown, the parking rack 1000 is composed of several parking racks 1100 stacked together, and each parking rack 1100 can be provided with 8 to 12 parking spaces, and the parking spaces are evenly distributed along the circumference of the circular parking rack 1100. The lifting assembly 2000 can be raised and lowered on the central column 4000 to reach different parking racks 1100, and can rotate around the central axis to horizontally rotate and transport the vehicle to an empty parking space.

[0042] like Figure 1 and Figure 3 ,as well as Figure 5 and Figure 6As shown, the transport assembly 3000 includes a loader 3100, a guide rail 3200, a pulling part 3300 and a limiting part 3400. The guide rail 3200 is laid on the parking layer frame 1100 and the lifting assembly 2000 respectively. The pulling part 3300 is used to pull the loader 3100 from the lifting assembly 2000 to the parking layer frame 1100, and the limiting part 3400 is used to fix the loader 3100 on the parking layer frame 1100. The transport assembly 3000 is mainly used to transport vehicles to different locations, wherein the loader 3100 is used to carry vehicles. The specific working requirements can be determined by those skilled in the art according to the actual situation. For example, the vehicle needs to be stably placed on the loader 3100, and the vehicle will not move or even fall during the movement of the loader 3100. The guide rail 3200 actually has multiple sections, some of which are set on the lifting assembly 2000 and some are set on the parking layer frame 1100, so that the loader 3100 can run according to the determined track. The pulling part 3300 can pull the loader 3100 from the lifting assembly 2000 to the parking rack 1100. When the loader 3100 needs to be transferred from the parking space of the parking rack 1100 to the lifting assembly 2000, the loader 3100 can be driven to operate by the power component arranged on the loader 3100, or other measures can be taken. For details, please refer to the subsequent description of this application. When the loader 3100 is parked on the parking space, in order to ensure that the loader 3100 and the vehicle are parked stably, the position of the loader 3100 needs to be stabilized by the limiting part 3400. The limiting part 3400 can adopt an electrically controlled brake unit arranged on the loader 3100, or other mechanical units can be arranged.

[0043] The controller is respectively connected to the lifting assembly 2000 and the transport assembly 3000 for communication. The controller sends control signals to the lifting assembly 2000 and the transport assembly 3000, as well as to various sensors arranged at other positions of the annular multi-story parking garage, so that various electrical components operate according to the set instructions. Specifically, when the vehicle enters the loading vehicle 3100 at the entrance of the bottom floor of the parking rack 1000, the driver gets off the vehicle. After the controller obtains the information, it controls the loading vehicle 3100 to enter the lifting assembly 2000 from the parking rack 1000. After the controller confirms that the loading vehicle 3100 is parked in the designated position of the lifting assembly 2000, it starts the relevant components to make the lifting assembly 2000 rise to the floor where the nearest parking space is located. If necessary, the lifting assembly 2000 rotates to achieve docking with the parking space. The controller controls the pulling part 3300 to pull the loading vehicle 3100 into the empty parking space of the parking layer rack 1100. The controller controls the limiting part 3400 to work to ensure that the loading vehicle 3100 carrying the vehicle is stably parked in the parking space.

[0044] When the user picks up the vehicle, the controller receives the instruction, and the lifting assembly 2000 arrives at the parking rack 1100 where the vehicle is located. If necessary, it rotates to achieve docking with the guide rail 3200 of the parking space where the vehicle is parked. The controller controls the operation of related components, and the loader 3100 runs from the parking space into the lifting assembly 2000. The controller then controls the lifting assembly 2000 to return to the bottom layer of the parking rack 1000 to release the vehicle. The entire vehicle pick-up and placement process does not require the participation of the driver or other operators, and can be fully automated. Multiple temporary parking docking positions can be set on each lifting assembly 2000, and multiple parking spaces can be set on each parking rack 1100. The lifting assembly 2000 can not only transport multiple vehicles to multiple parking spaces, but also receive vehicles that need to be taken out while parking vehicles, and the efficiency of vehicle parking is relatively high.

[0045] The annular multi-story stereoscopic parking garage provided by the present invention can store multiple cars at the same time in the parking rack 1000 through the transportation component 3000 and the lifting component 2000 that can carry cars. The lifting component 2000 can rotate around the central column 4000, and can quickly locate and obtain the car stored in any parking space in the parking rack 1000 according to user needs. The vehicle is parked without the need for a driver, and the transfer of the vehicle is achieved by relying on the controller and the transportation component 3000. The annular multi-story stereoscopic parking garage can realize full automation of picking up and placing vehicles.

[0046] Optionally, in one embodiment of the present application, Figure 3 and Figure 4 As shown, the lifting assembly 2000 includes a base 2100, a rotating disk 2200 and a driving unit 2300. The base 2100 is inserted into the central column 4000, the driving unit 2300 is fixedly arranged on the base 2100, and the rotating disk 2200 is arranged on the base 2100 and can rotate around the central axis under the drive of the driving unit 2300. The base 2100 is a mechanism directly connected to the central column 4000, which can move on the central column 4000 and can also carry multiple loaders 3100 and vehicles. The specific technical parameters and materials, etc., need to be designed and implemented by relevant technical personnel according to relevant safety standards and mechanical standards. Under the existing technical conditions, the base 2100 and the central column 4000 that can achieve the above functions exist. The rotating disk 2200 is equivalent to a moving part arranged on the base 2100. The rotating disk 2200 drives all the loading vehicles 3100 and the guide rails 3200 arranged on the rotating disk 2200 to rotate together on a certain horizontal plane, and the driving unit 2300 is a mechanism that provides the driving force for the rotation. The driving unit 2300 is also specifically connected to the controller for communication.

[0047] Optionally, in a specific implementation of the above embodiment of the present application, an annular toothed disk is provided on the inner edge of the rotating disk 2200, and the output shaft of the driving unit 2300 is meshed with the annular toothed disk; and a plurality of pairs of first guide rails 3210 are evenly arranged on the rotating disk 2200. The driving unit 2300 may be a motor, and a gear portion is provided at the top end of the power output shaft of the motor, and the gear portion is meshed with the annular toothed disk of the rotating disk 2200. When the motor rotates, the rotating disk 2200 can be driven to rotate. In fact, the power of the motor does not need to be very large. As long as effective measures are taken to reduce the friction between the rotating disk 2200 and the base 2100, a low-power motor can be used to drive the rotating disk 2200 to rotate.

[0048] Optionally, in another specific implementation of an embodiment of the present application, as Figure 3 As shown, the lifting assembly 2000 further includes a hydraulic lifting unit 2400 disposed between each pair of first guide rails 3210, the hydraulic lifting unit 2400 being close to the central column 4000 and being used to lift the first end of the first guide rail 3210; the first guide rail 3210 is connected to the surface of the rotating disk 2200 through a plurality of support pins, and the second end of the first guide rail 3210 is hinged to the rotating disk 2200. By adopting the technical solution in this implementation, the loader 3100 can complete the operation from the lifting assembly 2000 to the parking rack 1100 only under the drive of its own gravity. After the lifting component 2000 reaches the designated floor and completes docking with the parking space to be entered, the controller controls the hydraulic lifting part 2400 to work, lifts the first end of the first guide rail 3210, so that the entire first guide rail 3210 is tilted, and the first end is high and the second end is low. The second end is the outer edge end of the lifting component 2000. In this way, the loading truck 3100 loaded with vehicles will run into the parking space driven by its own gravity. A parking mechanism is set on the guide rail 3200 in the parking space, and the loading truck 3100 will stop when it reaches the designated position.

[0049] Correspondingly, the hydraulic lifting part 2400 can also be set on the guide rail 3200 of the parking floor, so that the inner side of the guide rail 3200 of the parking floor can be raised. When it is necessary to take the vehicle out of the parking space, the inner end of the guide rail 3200 is lifted to tilt the guide rail 3200 in the parking floor, and the loader 3100 automatically enters the docked horizontal first guide rail 3210.

[0050] Optionally, in another implementation of an embodiment of the present application, the first guide rail 3210 is tilted inward, and the angle between the first guide rail 3210 and the disk surface of the annular gear disk is 1° to 3° (not shown in the figure). The first guide rail 3210 is set in a non-horizontal posture, and the first guide rail 3210 has a certain tilt angle. When the loader 3100 enters the first guide rail 3210 of the lifting assembly 2000, it can rely on its own gravity to move into the rotating disk 2200, and a baffle or baffle bar is set on the inner edge of the rotating disk 2200 to prevent the loader 3100 from moving out of the first end of the first guide rail 3210. Setting the first guide rail 3210 inwardly can ensure that the loader 3100 can be stably placed on the lifting assembly 2000 when it is on the lifting assembly 2000.

[0051] Optionally, in another embodiment of the present application, Figure 3 As shown, the lifting assembly 2000 further includes a second guide rail 3220 corresponding to the first guide rail 3210; an annular groove is provided on the top surface of the base 2100, and the rotating disk 2200 is provided in the annular groove; the second guide rail 3220 is provided on the top surface of the base 2100. In order to ensure that the base 2100 of the lifting assembly 2000 has a high load-bearing stability, it is preferred to place the rotating disk 2200 in the middle of the top surface of the base 2100, the middle of the base 2100 is connected to the central column 4000, and the edge of the base 2100 is supported in the middle position of the base 2100 by a plurality of support beams, so that the entire base 2100 presents a triangular stable support structure. This arrangement can ensure that the base 2100 has good stability, but it will make it difficult for the first guide rail 3210 on the rotating disk 2200 to directly dock with the guide rail 3200 on the parking layer frame 1100, so it is necessary to set a section of the second guide rail 3220 on the top surface of the base 2100. The number of the second guide rail 3220 corresponds to the guide rail 3200 (hereinafter named as the third guide rail 3230) on the parking layer frame 1100. In this way, it can ensure that the rotating disk 2200 rotates freely, and the lifting assembly 2000 has a stable bearing structure, and can also ensure the smooth docking between the guide rails 3200 at various positions.

[0052] Optionally, in another embodiment of the present application, Figure 1 and Figure 5As shown, the guide rail 3200 includes a third guide rail 3230, and a pair of inclined mounting platforms 3240 are provided on each parking space of the parking layer frame 1100, and the third guide rail 3230 is provided on the inclined mounting platform 3240. The third guide rail 3230 is a guide rail 3200 provided on the parking layer frame 1100. In this embodiment, the third guide rail 3230 is provided at an angle and is placed on the inclined mounting platform 3240. The inclination angle of the inclined mounting platform 3240 should not be too large, and can be 2 to 5 degrees. The inclined mounting platform 3240, combined with the pulling part 3300 and the limiting part 3400, can enable the loader 3100 to use its own potential energy to naturally fall from the parking space of the parking layer frame 1100 and run into the docked lifting assembly 2000.

[0053] Optionally, in one of the embodiments of the present application, Figure 5 and Figure 6 As shown, the pulling part 3300 and the limiting part 3400 are arranged between the inclined mounting platform 3240; the pulling part 3300 includes a slope block 3310, a telescopic rod 3320 and a connecting hook 3330, the connecting hook 3330 is hinged at the top of the telescopic rod 3320, and the slope block 3310 is arranged on the lifting assembly 2000. The working principle of the pulling part 3300 is as follows: when the lifting assembly 2000 completes docking with the parking layer frame 1100, the telescopic rod 3320 extends toward the lifting assembly 2000, when the telescopic rod 3320 pushes the connecting hook 3330 to reach the slope block 3310 of the lifting assembly 2000, the connecting hook 3330 bends upward, hooks the loading vehicle 3100, and then the telescopic rod 3320 retracts, pulling the loading vehicle 3100 to run in the third guide rail 3230 of the parking layer frame 1100 until it reaches the set parking position. Optionally, a connecting beam specifically adapted to dock with the connecting hook 3330 is provided on the loader 3100. The telescopic rod 3320 is a hard and telescopic rod, and a power mechanism capable of driving the telescopic rod to move is provided, which is placed at the other end of the telescopic rod and is specifically provided on the parking layer frame. The hard telescopic rod 3320 can ensure that the pushing connecting hook 3330 moves toward the docked lifting assembly until the ramp block 3310 reaches the bottom of the loader 3100 and hooks the loader 3100.

[0054] Optionally, in combination with the above embodiments, in a specific implementation of the present application, Figure 5 and Figure 6As shown, the limiting part 3400 includes a connecting seat 3410 and a limiting beam 3420, the limiting beam 3420 is hinged to the connecting seat 3410, and the rotation angle of the limiting beam 3420 is 90°. Specifically, the limiting part 3400 can be hidden in a horizontal position or a nearly horizontal position. When the pulling part 3300 pulls the loader 3100 to a set position, the limiting part 3400 stands up to fix and park the loader 3100. A driving motor or other driving system is also provided in the connecting seat 3410, which is connected to the controller and receives the command of the controller. When the loader 3100 reaches the parking position, the limiting beam 3420 is rotated to make it stand upright, so that the loader 3100 is confined in the parking space. When the vehicle needs to be retrieved, the controller controls the limiting beam 3420 to be placed horizontally, releasing the limit on the loader 3100, and the loader 3100 moves toward the lifting assembly 2000 under the action of its own gravity until it enters the lifting assembly 2000 and stops.

[0055] Optionally, in one embodiment of the present application, Figure 7 As shown, the cross-sectional shape of the central column 4000 is a square, and a traction system is provided at the top of the central column 4000; a plurality of suspension seats 2500 are provided on the lifting assembly 2000, and the traction system is connected to the suspension seats 2500. The traction system can adopt an electric hoist in the prior art, or a suspension traction system used in elevator technology, and a pulley system composed of a traction system and a suspension seat 2500 is formed. This structure can be realized in the prior art, but since it is not the focus of the invention of this application, it will not be explained in detail. The central column 4000 with a square cross-sectional shape can ensure that the central column 4000 has good structural rigidity, and can also ensure that the lifting assembly 2000 can stably rise and fall on the central column 4000.

[0056] Those skilled in the art will appreciate that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, altered, combined, or deleted.
