Technical Field

The invention relates to the field of parking, in particular to a parking device for improving the utilization efficiency of a parking lot, and particularly provides a parking method.

Background

With the development of economy and the improvement of living standard, the automobile has more and more reserves, which not only causes great traffic pressure, but also has more and more outstanding parking problem. The problem of difficult parking is mainly embodied in that the existing parking spaces can not meet the increasing parking space requirements, the empty parking spaces which can be parked after entering the parking lot are difficult to find and time-consuming, and the like, and the problem of difficult parking is particularly prominent in large cities.

In recent years, parking problems are improved, for example, manual card taking and card receiving are replaced by scanning license plates when parking is carried out, and the vehicle can directly enter or leave without extending a driver handle out of a window.

To solve the problem of lack of parking spaces, the multistory parking garage is used in many underground parking garages. The mode makes full use of the vertical space of the parking lot, and realizes that the parking space is increased to two or even more layers by traction. The stereo parking scheme improves the capacity of the underground parking lot, but the stereo parking scheme does not solve the parking problem better, and is mainly embodied in the following aspects:

1. the parking space is not fully utilized: the three-dimensional parking scheme adopts a parking space moving mode, and a vacant position needs to be reserved in a unit for moving other parking spaces. Such parking lots usually have only 6-8 spaces in one unit, that is, every 5 or 7 vehicles need to be vacated by one space, so that the parking space is not fully utilized.

2. The parking space is not fully utilized: the design of such a parking lot requires a large space to be left as a passageway, which is mainly used for the entrance and exit of vehicles. It has been observed that the space of the access is in most cases free, which leads to a certain waste of scarce parking space.

3. The problem of finding a parking space is not solved: get into the parking area after probably needing to spend some time just can find the parking stall that can park, multilayer structure blocks the sight very easily, more is unfavorable for discovering the empty parking stall, and this kind of sky parking area scheme still has the problem that the empty parking stall is difficult to find, and the parking stall that is in the upper strata moreover needs a lot of conversions just can fall to ground, wastes time and energy relatively.

4. The use scenario is limited and not applicable to ground parking lots: the multistory parking garage needs to pull the vehicle to the upper layer, the whole device needs to have a certain height, and the multistory parking garage does not have sufficient installation conditions for the open ground outdoor parking garage, and the surrounding environment can be shielded by the multistory design.

Therefore, a parking solution suitable for a ground open parking lot is urgently needed for cities, particularly large cities and extra-large cities with limited use space.

Firstly, the invention is utilized to plan the parking lot on the ground in different areas: according to the scheme, a parking area is longitudinally divided into 8 independent parking subareas, as shown in fig. 2, namely an area A, an area B, an area C, an area D, an area E, an area F, an area G and an area H, wherein the two front parking stalls of each subarea are access areas of vehicles, and the vehicles can be parked or departed in the access areas.

Preferably, the rotating shaft is of a hollow design, as shown in fig. 5, the vehicle-carrying tray rotation control device is arranged in the rotating shaft and electrically connected with the parking controller, and as an embodiment, the vehicle-carrying tray rotation control device may also be arranged in the chassis and drivingly connected with the rotating shaft; optionally, the vehicle carrying tray rotation control device is arranged at a turning of the conveying device, and when the vehicle carrying tray is driven to the turning, the vehicle carrying tray rotation control device works and drives the vehicle carrying tray to rotate.

As shown in fig. 6, when the vehicle carrying tray rotation control device 4 is externally arranged, the vehicle carrying tray rotation control device 4 is arranged at four turning places below the conveying device 1, when the vehicle carrying tray 21 is driven to the turning places, a rotation control part of the vehicle carrying tray rotation control device 4 is in driving connection with the rotating shaft 23, so that the rotating shaft 22 is controlled to rotate, and when the tray leaves the turning places, the connection between the external control rotation device 4 and the rotating shaft 22 is disconnected.

Preferably, the transmission means may be bidirectional along the conveying means.

Preferably, the size of the chassis can be changed according to layout specifications so as to reduce the space required by the chassis during turning and improve the utilization rate of the space of the parking lot.

As an optional mode, the vehicle carrying tray rotation control device can adopt a steering engine, and the reverse rotation of the vehicle carrying tray is realized by setting and controlling the angle of each rotation of the vehicle carrying tray; optionally, the vehicle carrying tray rotation control device may also adopt a rotating motor, a rotating shaft of the rotating motor is connected with the vehicle carrying tray, and the rotating motor is controlled to rotate in the forward and reverse directions to drive the vehicle carrying tray to rotate in the forward and reverse directions.

As shown in fig. 3 and 4, the conveying device 1 adopts an endless track, a planar conveyor belt or a roller conveyor belt, a plurality of chassis 23 are placed on the conveying device 1 or fixed on the conveying device 1, when the endless track is adopted, the adjacent chassis 23 are connected in series through connecting pieces 25, and when the planar conveyor belt or the roller conveyor belt is adopted, the adjacent chassis can be independent.

When the conveying device 1 adopts a plane conveying belt or a roller conveying belt, a plurality of chassis 23 are placed or fixed on the conveying belt, the conveying belt drives the chassis 23 to transmit, and the vehicle-carrying tray 1 is connected with the chassis 23 through the rotating shaft 22 so as to rotate relative to the chassis 23.

Each vehicle carrying tray can rotate relative to the chassis, the form of the rotating shaft can be designed according to needs, the mode for realizing relative rotation can be designed according to needs, and the vehicle carrying trays can be regarded as the same technical characteristics as long as the same functions are realized; the vehicle-carrying tray rotation control device 4 can control the vehicle-carrying tray 21 to start rotation or stop rotation when the rotation is needed, and the vehicle-carrying tray rotates in the opposite direction after the conveying direction of the chassis 23 is changed; preferably, the vehicle carrying tray 21 and the chassis 23 rotate simultaneously and in opposite directions, and each rotation angle is the same, i.e. the vehicle carrying tray and the chassis rotate synchronously in opposite directions.

When the conveying device adopts rail conveying, the driving device controls the chassis of the transmission device to move on the rails, and the driving device controls the chassis to move in a plurality of ways in the prior art, for example, a motor drives the caterpillar tracks to move, a certain tray drives all the chassis to move, and the chassis can be driven in two directions along the rails.

The track comprises a strip-shaped track and a semi-annular track, a plurality of chassis are arranged on the track, and adjacent chassis are mutually connected.

The chassis is also provided with a vehicle carrying tray for parking, the vehicle carrying tray is connected with the chassis through a hollow rotating shaft, and when the vehicle carrying tray reaches four turning positions, the position of the hollow rotating shaft of the vehicle carrying tray rotating control device can pop out a shaft which can rotate, and the shaft is clamped or meshed with the vehicle carrying tray, so that the vehicle carrying tray can rotate relative to the chassis.

The driving device adopts a driving motor to drive the roller to rotate to drive the transmission device to transmit; the driving motor can also be connected with a head-tail transmission device, such as the transmission devices at the starting positions A1 and A0, and the forward and reverse rotation transmission of the transmission devices is realized through the driving of the driving motor.

The parking controller stores preset parking space information and transmission device information, can record the transmission device change of each area and the corresponding parking space information in real time, calls the last recorded no-load condition of the parking position in the subarea in real time after receiving a scheduling instruction, controls the forward or reverse operation of the conveying device after obtaining the no-load parking space position condition, and schedules the no-load transmission device to the in-out area position.

When parking, the parking controller controls the transmission device to rotate forwards or reversely to a proper parking space; when the vehicle leaves the parking lot, the parking controller obtains the current corresponding parking space information of the vehicle according to the input vehicle carrying tray number, and then controls the conveying device to convey the vehicle to the in-out area.

In the process of dispatching the target vehicle carrying tray to the entrance and exit area, preferably, the shortest path is obtained through a traversal method according to the parking space and transmission device information recorded in real time for transmission.

Example two as shown in fig. 8: a parking method using the parking apparatus of the first embodiment, the method for parking includes:

and S1, when the vehicle drives into the vehicle carrying tray, the transmission device receives the transmission signal to transmit the transmission device, and the position information of the transmission device and the no-load information of the parking space are recorded in real time.

Before step S1, the parking lot has been arranged in independent partitions, two-way conveyable conveying devices are respectively laid in each independent partition, each parking space is provided with a transmission device, and each parking space and the vehicle-mounted tray correspond to corresponding numbers, so as to complete the construction of the parking lot infrastructure.

As shown in fig. 2, for example, a parking area a, a0-a15 represents a position in the same area a unit where a vehicle can be parked, and the position is fixed and does not change corresponding to a point on the ground, i.e., the parking space does not change, and is used to determine the position of the vehicle at a certain time for subsequent scheduling of the transmission.

In one embodiment, after receiving the operation signal of the parking controller, the transmission device with the vehicle is driven to rotate in a certain direction, when the static time of the transmission device exceeds a certain threshold value, the information of the parking space where the vehicle is parked last is recorded, when the parking information of the vehicle is changed, the position information of the vehicle is recorded in real time, for example, when the vehicle is parked, the tray a1 is in the A0 position, when the transmission device is operated to the A3 position, the current tray a1 is in the A3 parking space, and the information of the parking spaces of other vehicles is recorded in real time.

In the prior art, there are various ways of acquiring the current position information of the transmission device, for example, visual identification, electronic tag identification, displacement sensor and the like.

And S2, when no-load dispatching or vehicle leaving is needed, the parking controller controls the conveying device to convey the target transmission device to the entering and exiting area.

When the parking spaces in the subareas are free/empty, the parking controller controls the conveying device to operate and conveys the empty transmission device to the in-out subarea; when the vehicle needs to leave the field, the parking controller controls the driving device to drive the transmission device to transmit the target transmission device to the entering and exiting area.

Taking the partition a in fig. 2 as an example, the two positions a1 and a0 are the positions where the empty spaces of the partition are parked. As long as the partition unit has free parking spaces, the partition unit can be automatically dispatched to the positions of A1 or A0. Therefore, whether the partition has a free parking space or not can be known only by looking at whether vehicles exist in the access partition A1 or the A0, and the parking space is clear at a glance without the need of a vehicle owner to find the parking space.

When the vehicle needs to leave the field, the user can input the corresponding vehicle carrying tray number, and the parking controller drives the conveying device to convey the corresponding vehicle carrying tray to the position of A1 or A0 according to the position information of the transmission device recorded in the parking controller, so that the vehicle can conveniently drive away. When the vehicle is driven away, the A1 or A0 position can generate a free parking space, at the moment, if no other vehicle is out of the field, the transmission device is not moved, and when the vehicle enters, the vehicle entering the field can be directly parked at the position.

When a plurality of vehicles continuously drive away, the vacant parking spaces can be operated into the partition unit along with the conveying device, and at the moment, a plurality of vacant parking spaces are arranged in the partition unit. If another vehicle comes in, the vehicle is firstly stopped at the position A1 or A0 where the last driven vehicle is free, then the transmission starts to operate, and other free parking spaces in the partition unit are dispatched to the position A1 or A0, so that a plurality of continuous approach vehicles can be conveniently and continuously parked.

By the method, 128 vehicles can be parked on the same plane of the ground parking lot with the length of 50 meters by 50 meters, and therefore, the capacity of the parking lot can be improved to at least 171% of the original capacity by the method.

And for the transmission device in the linear motion state, the corresponding vehicle-carrying tray rotation control device does not work.

Preferably, the vehicle carrying tray rotation control device of the parking device controls the vehicle to keep the same vehicle direction as that of parking before entering the access area to leave the field, and preferably, the transmission device carrying the vehicle keeps rotating at the turning position of the conveying device, namely, at the angle opposite to that of the chassis, so as to facilitate the rapid leaving of the vehicle.

As shown in fig. 7, taking the circular track as an example, the chassis conveying direction of the transmission device is consistent with the track direction, and in the turning area of the track, the chassis conveying direction also changes along with the change of the track direction; taking a position example of every 15 degrees in the figure, the position 1 is the original direction, namely the chassis conveying direction is not changed, the conveying direction is rotated clockwise 15 degrees relative to the original direction at the position 2, the conveying direction is rotated clockwise 30 degrees compared with the original direction at the position 3, and the conveying belt is rotated clockwise 90 degrees relative to the original direction when conveyed to the position 7.

Then, in order to keep the direction of the vehicle head unchanged before leaving the field, the opposite direction selection of the vehicle carrying tray relative to the chassis conveying direction is needed: at the position 1, the direction of the vehicle head is consistent with the direction of transmission, the vehicle carrying tray does not rotate relative to the chassis, at the position 2, the direction of transmission is rotated by 15 degrees clockwise compared with the original direction, the direction of the vehicle head is rotated by 15 degrees reversely relative to the direction of transmission, so that the direction of the vehicle head is not changed compared with the original direction, when the vehicle carrying tray is at the position 7, the direction of transmission is rotated by 90 degrees clockwise compared with the original direction, the direction of the vehicle head is rotated by 90 degrees reversely relative to the direction of transmission, and the direction of the vehicle head on the vehicle carrying tray is always unchanged with the original direction in the process of entering and leaving the turning position.

The invention adopts a unique relative rotation design, the chassis and the conveying device synchronously rotate in the same direction, the vehicle-carrying tray is rotationally connected with the chassis through a rotating shaft, and the vehicle-carrying tray is driven to rotate horizontally along the rotating shaft by the vehicle-carrying tray rotation control device; at the turning position, the chassis rotates by more or less degrees, and the vehicle-carrying tray correspondingly rotates by more or less degrees in the opposite direction, so that the original direction of the vehicle-carrying tray is always kept unchanged in the turning process of the conveying device, the direction of the vehicle is also kept unchanged, and the vehicle can be conveniently driven out; optionally, the direction of the head of the vehicle before leaving the field may be opposite to the direction of the head of the vehicle when entering the field, and the direction of the vehicle before leaving the field is considered to be the same as the direction of the original vehicle.

As a further improvement, when the transmission needs to be transferred, the shortest path method is adopted to transfer the target transmission to the entrance and exit area, so that the transfer time is shortened, and the transfer efficiency is improved, for example, when the vehicle or the empty vehicle tray of the user is in the parking space a5, the vehicle or the empty vehicle tray rotates anticlockwise to the parking space a1 or a 0.

As a further improvement, when a plurality of empty vehicle carrying trays are arranged in the independent subarea, the vehicle carrying tray closest to the independent subarea is dispatched to the access area.

As one of the alternatives: the vehicle-carrying tray rotation control device is arranged in a hollow rotating shaft or a chassis between each vehicle-carrying tray and the chassis, in a specific embodiment, an output shaft of a steering engine can be used for directly or indirectly controlling the vehicle-carrying trays to rotate, each vehicle-carrying tray starts the rotation control device at a turning position, starts relative rotation, leaves the turning position and stops the rotation control device, and the direction of the vehicle head and the advancing direction are recovered to be on the same straight line.

As a second alternative: the vehicle-carrying tray rotation control device is fixedly installed at the turning of the conveying device, the vehicle-carrying tray starts to be started when running to the turning, the vehicle-carrying tray rotates by using external force, and therefore the vehicle-carrying tray rotates reversely relative to the chassis.

Example three: an annular conveying system comprises any one of the conveying devices, a transmission device and a driving device, wherein the transmission device comprises a chassis, a rotating shaft and a vehicle-carrying tray, the chassis is placed on the conveying device, and the chassis is connected with the vehicle-carrying tray through the rotating shaft;

the transmission device is used for carrying the transmission device and transmitting the transmission device;

and the driving device respectively controls the rotation of the conveying device and the transmission device correspondingly.

As a further improvement, the conveying device adopts an annular track or a plane conveyor belt.

As a further improvement, the driving devices are respectively a driving motor and a vehicle-carrying tray rotation control device, the driving motor drives and controls the conveying device, and the vehicle-carrying tray rotation control device controls the transmission device; optionally, the vehicle-carrying tray rotation control device may be directly arranged in the rotating shaft of the transmission device, or may be externally arranged at a turning position of the transmission device and in driving connection with the rotating shaft.

By adopting the annular conveying system, the space utilization rate of a parking lot can be improved, the orderly operation of vehicles is realized, the intensive parking and the rapid access of a plurality of vehicles are realized, the site utilization rate is improved, and the time is saved.

In the above embodiment, the chassis of the transmission device may be fixedly connected with the conveyor belt or the track of the conveying device, or may be directly placed on the conveying device and move together with the conveying device; when the vehicle carrying tray and the chassis are at a turning position, the vehicle carrying tray can synchronously and reversely rotate, and also can asynchronously and reversely rotate, and the vehicle carrying tray only needs to keep the same vehicle direction after going out of the turning position and before going into the turning position.

The annular conveying system can also be used in other scenes for storing and taking high-density articles, such as logistics sorting, warehousing transportation, production transportation and the like.
