Abstract
Description
Technical Field
[0001] This invention relates to the field of underground parking technology, and in particular to an active bidirectional turntable system based on a circular intelligent underground parking lot. Background Technology
[0002] For intelligent underground parking lots, parking and retrieval efficiency is a critical issue that urgently needs to be addressed, directly impacting the timeliness and energy consumption of the parking system. In mainstream circular intelligent underground parking systems, turntables are typically used to transport vehicles to their designated parking spots. The individual turntable rotation during vehicle transport consumes significant energy and time, resulting in low parking and retrieval efficiency. This is especially true for commonly used circular intelligent underground parking lots, such as those in residential areas, hotels, and airports, where the limited space leads to longer turntable rotation times and further reduces parking and retrieval timeliness. Furthermore, these types of parking lots often have only a single vehicle entrance and exit, further reducing efficiency. Therefore, improving the vehicle transport efficiency of circular intelligent underground parking lots is essential, particularly during peak commuting hours when there are many people parking and retrieving their vehicles. Failure to provide reasonable parking and retrieval times will result in greater user losses, severely impacting user experience and increasing operating costs.
[0003] In the design of intelligent underground parking lots, whether large or small, rotary table transportation is the most scientific and efficient energy-saving measure. It can effectively save space and improve the speed of transport vehicles. For commonly used prefabricated circular intelligent underground parking lots, setting up a rotary table can directly reduce space loss during underground transportation, save land resources, and improve economic efficiency. However, current intelligent underground parking lots, based on calculations of the parking and retrieval system, require a faster rotary table rotation speed to shorten parking and retrieval times. But a rotary table with an excessively fast rotation speed will have a greater centripetal force, and since the friction between the vehicle and the rotary table remains constant, it may lead to safety accidents. Furthermore, although the specifications provide suggestions for the most suitable rotary table speed, this method of improving transportation efficiency only provides a fixed indicator and cannot be further adjusted according to actual user needs, which to some extent limits the efficiency of underground parking lots. Summary of the Invention
[0004] The purpose of this invention is to provide an active bidirectional turntable system based on a circular intelligent underground parking lot, which solves the technical problem of low parking lot efficiency.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] An active bidirectional turntable system based on a circular intelligent underground parking lot includes a control device, a mechanical turntable canopy, an underground parking lot body, and a mechanical turntable. The mechanical turntable is located inside the underground parking lot body and is configured for vertical transmission. The mechanical turntable canopy is located directly above the mechanical turntable. The control device is connected to the mechanical turntable canopy and the underground parking lot body. The control device is used to acquire real-time data on the vehicles parked in each parking space inside the underground parking lot body. The mechanical turntable is configured as a rotatable disc structure. The underground parking lot body includes several parking lot body rotating layers and a mechanical rotating shaft. The mechanical rotating shaft is engaged with the parking lot body rotating layers and drives one layer of parking lot body rotating. When parking or retrieving a vehicle, the control device determines the parking space where the vehicle needs to be parked. The control device controls the mechanical turntable to move downwards and rotate simultaneously, while also controlling the corresponding parking lot body rotating layer that needs to be retrieved to rotate. The rotation direction of the parking lot body rotating layer is opposite to that of the mechanical turntable.
[0007] Furthermore, the direction in which the mechanical turntable picks up or places a car on the ground is taken as the first vector side, with the direction being the direction the car's front faces. Then, the parking space where the car needs to be picked up or the parking space where the car is stored is taken as the second vector side, with the direction being the direction the car's front faces. The angle between the first and second vector sides is the angle of total rotation required. When the angle between the vectors is less than 25°, the rotating layer of the parking lot does not work. When the angle between the vectors is greater than 25°, the angle of rotation of the rotating layer of the parking lot is an integer multiple of the two parking spaces, and not less than half of the angle of total rotation required.
[0008] Furthermore, the mechanical turntable is powered by a motor equipped with a control device. The motor's drive shaft is connected to the rotating wheel, and the mechanical turntable is fixedly connected to the turntable via bearings. The rotation of the rotating wheel generates friction with the turntable, causing it to rotate. The control device issues a stop / retrieve command to control the motor, enabling the turntable to complete its intelligent rotation function. The parking lot's rotating layers are connected to the mechanical turntable via snap-fit connections between each layer and the mechanical turntable. The intelligent rotation of a single-layer parking lot is achieved using a motor controller. Embedded snap-fits are installed on the mechanical turntable, and snap-fit insertion holes are provided at each layer's vehicle frame nodes. The opening and closing of the snap-fits are controlled by the controller, which in turn regulates the operation through stop / retrieve commands issued by the control device.
[0009] Furthermore, a small gear and a large gear are meshed at the center of the upper end of the turntable base plate. The motor shaft is connected to the small gear. Several crossbars are connected to the large gear at one end and are arranged in a radiating manner. Rollers are set at the bottom of the other end of the crossbars. Roller grooves are provided at the edge of the turntable base plate, and the rollers are set in the roller grooves. The upper parking plate is fixed on the large gear and crossbars.
[0010] Furthermore, a rotary motor is installed at the bottom of the mechanical shaft, which drives the mechanical shaft to rotate. There are four mechanical shafts, which are installed between the underground parking lot body and the mechanical turntable.
[0011] Furthermore, the mechanical rotating shaft includes a rotating column and a snap ring. The snap rings are spaced apart on the rotating column, and each snap ring corresponds to a rotating layer of the parking lot. The snap rings are designed to be retractable.
[0012] Furthermore, the buckle ring includes several buckles, which are embedded in the rotating column and can be extended and retracted, with equal arcs between the buckles.
[0013] The present invention, by adopting the above-described technical solution, has the following beneficial effects:
[0014] This invention improves parking and retrieval efficiency by half. Through the rotation of a mechanical turntable and a specific level of the underground parking garage, both can move in the same direction, allowing for faster entry and exit. This significantly increases parking efficiency, better meeting the needs of peak commuting hours. The efficient bidirectional rotation method further enhances vehicle transport efficiency. This proactive bidirectional rotation maximizes the operational efficiency of the circular underground parking garage. By installing a mechanical turntable on the garage floor, the steel frame of the required parking space actively rotates, supplemented by the rotation of a top-level lifting turntable. The simultaneous bidirectional rotation of both the mechanical and lifting turntables achieves highly efficient parking and retrieval operations. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.
[0022] like Figure 1-5 As shown, an active bidirectional turntable system based on a circular intelligent underground parking lot includes a control device, a mechanical turntable canopy A, an underground parking lot body B, and a mechanical turntable. The mechanical turntable is located inside the underground parking lot body B and is configured for vertical transmission. The mechanical turntable canopy A is located directly above the mechanical turntable. The control device is connected to the mechanical turntable canopy A and the underground parking lot body B. The control device is used to acquire real-time data on the vehicles parked in each parking space inside the underground parking lot body B. The mechanical turntable is configured as a rotatable disc structure. The underground parking lot body B includes several parking lot body rotating layers 8 and mechanical rotating shafts 9. The mechanical rotating shafts 9 are engaged with the parking lot body rotating layers 8 and drive each parking lot body rotating layer 8 to rotate. When parking or retrieving a vehicle, the control device determines the parking space where the vehicle needs to be parked. The control device controls the mechanical turntable to move downwards and rotate simultaneously, while simultaneously controlling the corresponding parking lot body rotating layer 8 to rotate. The parking lot body rotating layer 8 rotates in the opposite direction to the mechanical turntable.
[0023] In this embodiment of the invention, the direction in which the mechanical turntable picks up or places a car on the ground is taken as the first vector side, with the direction being the direction the front of the car is facing. Then, the parking space where the car needs to be picked up or the parking space where the car is stored is taken as the second vector side, with the direction being the direction the front of the car is facing. The angle between the first vector side and the second vector side is the angle of total rotation required. When the angle between the vectors is less than 25°, the rotating layer 8 of the parking lot does not work. When the angle between the vectors is greater than 25°, the angle of rotation of the rotating layer 8 of the parking lot is an integer multiple of the two parking spaces and is not less than half of the angle of total rotation required.
[0024] The mechanical turntable is powered by a motor, which is equipped with a control device. The motor's drive shaft is connected to the rotating wheel, and the mechanical turntable is fixedly connected to the turntable via bearings. The rotation of the rotating wheel generates friction with the turntable, causing it to rotate. The control device issues a stop / retrieve command to control the motor, enabling the turntable to complete its intelligent rotation function. The parking lot's rotating layer 8 is achieved by setting up snap-fit connections between each parking lot layer and the mechanical turntable. The intelligent rotation of a single parking lot layer is realized using the motor's controller. Embedded snap-fits are set on the mechanical turntable, and snap-fit insertion holes are set at each layer's vehicle frame nodes. The opening and closing of the snap-fits are controlled by the controller, which in turn regulates the operation through the stop / retrieve commands issued by the control device.
[0025] like Figure 1As shown, embedded buckles are set on the mechanical rotating shaft, and buckle insertion holes are set at each frame node. The opening and closing of the buckles are controlled by an intelligent controller, which is regulated by parking and retrieval commands issued by the intelligent parking system. The specific intelligent rotation process is as follows: (a) In the parking command, such as Figure 1 As shown, firstly, based on the parking space information transmitted by the intelligent parking system, such as parking space number 5 on the 3rd floor, this parking space is located at the position where the vehicle to be parked is rotated 180°. Then, the intelligent parking system performs calculations and analyses, and then issues instructions to control the lifting platform to rotate 45° clockwise and the vehicle frame to rotate 45° counterclockwise. Finally, the lifting platform descends to the 3rd floor and directly moves into the parking space. By rotating in both directions simultaneously, the vehicle to be parked is quickly moved to the appropriate parking position, reducing parking time by half and maximizing parking efficiency. (b) In the vehicle retrieval instruction, the parking space information transmitted by the intelligent parking system is also used, and then the intelligent parking system performs calculations and analyses to select an efficient bidirectional rotation method to improve the efficiency of vehicle transportation out of the garage. Through this active bidirectional rotation method, the circular underground parking garage can achieve the highest efficiency operation.
[0026] In embodiments of the present invention, such as Figure 2-3 As shown, a small gear 6 and a large gear 5 are meshed at the upper center of the turntable base plate 1. The shaft of the motor 7 is connected to the small gear 6. Several crossbars 4 are connected at one end to the large gear 5 and are arranged in a radiating manner. Rollers 3 are located at the bottom of the other end of the crossbars 4. Roller grooves 2 are provided at the edge of the turntable base plate 1, and the rollers 3 are located in the roller grooves 2. The upper parking plate is fixed on the large gear 5 and the crossbars 4. A rotary motor is provided at the bottom of the mechanical shaft 9, which drives the mechanical shaft 9 to rotate. There are four mechanical shafts 9, which are located between the underground parking lot body B and the mechanical turntable.
[0027] The mechanical rotating shaft 9 includes a rotating column 10 and a snap ring. The snap rings are spaced apart on the rotating column 10, and each snap ring corresponds to a rotating layer 8 of the parking lot. The snap rings are telescopic. The snap ring includes several snaps 11, which are embedded in the rotating column 10 and are telescopic. The snaps 11 are set with equal arc between them.
[0028] This invention can solve the problem of parking and retrieval efficiency in intelligent underground parking lots to a certain extent. Specifically, it sets up a mechanical turntable on the bottom plate of the underground parking lot, so that the steel frame of the required parking space can rotate actively. This is supplemented by the rotation of the top-level lifting turntable. The mechanical turntable and the lifting turntable rotate in both directions at the same time, realizing efficient operation of parking and retrieval.
[0029] A turntable is a device that uses bearings to drive mechanical rotation. In a circular underground parking garage, the bearings rotate the mechanical frame to adjust the orientation of parking spaces. This structure allows for incredibly precise rotary motion. It is widely used in the rotary motion of complex equipment such as tower parking systems, industrial robots, and high-precision medical devices.
[0030] The turntable device includes: 1. a mechanical turntable at the bottom of the underground parking lot, a motor inside the turntable, an intelligent control system on the motor, rotating wheels and bearings, and a mechanical rotating shaft on the turntable; (See the top view and cross-sectional view of the parking lot.) Figure 2 and Figure 3 The working mechanism is as follows: The mechanical turntable is powered by a motor equipped with an intelligent control system. The motor's drive shaft is connected to the rotating wheel, and the mechanical rotating shaft is fixedly connected to the turntable via bearings. The rotation of the rotating wheel generates friction with the turntable, causing it to rotate. The intelligent parking system of the underground parking lot issues a parking / retrieval command, which is controlled by the intelligent control system on the motor to enable the turntable to complete its intelligent rotation function. In the proposed invention, intelligent rotation is achieved by setting up snap-fit connections between each level of the parking lot and the mechanical rotating shaft, utilizing the intelligent controller on the motor to realize intelligent rotation of a single-level parking lot.
[0031] The active bidirectional turntable device increases parking and retrieval efficiency by half. It utilizes an intelligent control system to achieve rapid real-time calculation and execution of operations, and controls the operation of mechanical components, giving the entire system intelligent attributes. It can intelligently select the best parking solution and coordinate mechanical operations.
[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
