Description

Stereoscopic parking lot pitching type access unit based on old community

Technical Field

The invention relates to the technical field of intelligent parking lots, in particular to a stereoscopic parking lot pitching type access unit based on an old community.

Background

At present, in the urban life, automobiles play an increasingly important role, private automobiles become one of the main choices for the people to go out, and with the popularization of automobiles, certain problems are brought, and the difficulty in parking is one of the main choices.

In the related art, there are many products of three-dimensional parking garages, including planar mobile three-dimensional parking equipment, vertical circulation mechanical garage, and simple lifting and horizontal moving type parking garages, however, the parking garages in the related art still have many problems, specifically:

as shown in fig. 1 and 2, for the plane moving type three-dimensional parking facility, the vertical circulation type mechanical garage (hereinafter, referred to as a translation type and a vertical type) has an advantage of storing a car having an area capacity two times or even more than an area capacity by using a vertical space thereof in a limited area, for example: a typical example in Beijing is a vertical parking building at the general clinic of an air force hospital, but the comparison between the hospital and a community shows that the hospital is in a working state, so that the noise problem does not need to be considered. The environment in a residential area is relatively quiet, and most residents are affected by noise, but if the influence is to be reduced, the effect of the efficiency of a vertical parking building is affected by only a relatively large distance, or the traffic flow or the power of the residential area is reduced, and the effect of the efficiency of the vertical parking building is not suitable for the residential area.

In addition, in some communities, as shown in fig. 2, a translational parking lot is a biggest problem in a community built before 2000 years, in the existing situation, vehicles parked under trees and at a building doorway are visible everywhere, residents are also used to the translational parking lot, the translational parking lot is bound to involve the problem of transplanting trees, the living quality and the environment of the residents are indirectly affected, objections of the residents must be met, meanwhile, the two parking devices are high in complexity and need to be operated by special persons, and therefore the two parking devices are not suitable for solving the parking problem of old communities and are suitable for reconstruction of newly built communities or middle-grade communities.

In contrast, as shown in fig. 3, the three-car space width of the parking garage of the simple up-down-and-traverse type is still useful between buildings in a residential area. There still exist some problems, one of which is the limitation of construction, which can be constructed only between two buildings and does not affect the lighting of residents, which makes the construction limited. Secondly, the use mode is that five vehicles share the structure of a device, and in use, the time of entering and leaving the garage can cause a lot of waiting time, and in the peak time period of morning and evening, the time is money, and the waiting often causes the extremely poor user experience and brings congestion for the very narrow residential area road, so the simple parking garage is also very problematic in the use of old residential areas.

Disclosure of Invention

The present application is based on the recognition and discovery by the inventors of the following problems:

in the modern urban life, automobiles play an increasingly important role, and private automobiles become one of the main choices for the people to go out. According to the authority data of the State administration (taking Beijing as an example for explanation), the constant population of the Beijing in 2015 is 2170 ten thousand, and according to the data of the Beijing administration, the motor vehicles in the whole market are reserved for 586.7 ten thousand by 9 months in 2017. The popularity of the automobile can be seen. Along with the popularization of automobiles, certain problems are brought about, and one of the problems is that parking is difficult.

As shown in fig. 4, the general survey report of the parking resources in beijing city according to 2017. The total amount of parking spaces in Beijing urban areas is 382 thousands, the demand of parking at night is 384 thousands, the total amount of supply and demand of parking at night is equivalent, but the space distribution of parking spaces is unbalanced, and the unbalanced gap of the parking spaces in residential areas is 129 thousands. Wherein the serious lack area in the three rings accounts for 84 percent, and no sufficient space area exists in the five rings. By the end of 2016, the total number of the parking spaces in the urban area of the whole city is finally determined to be 382 thousands, wherein 219 thousands of parking spaces exist in the residential area. It should be noted that the 129 ten thousand gaps are not obtained by directly subtracting the total night parking demand of 320 ten thousand in the residential area from the number of cars 219 ten thousand in the residential area, but are obtained by calculating the difference between the night parking amount and the parking space in the residential area on each residential area and the surrounding roads and then accumulating according to the principle of no cross-regional sharing. In spatial distribution, parking space resources are also unbalanced. The parking space resources are mainly concentrated in five rings outside the four rings, and the total number of the parking spaces is 205 ten thousands, which accounts for about 54 percent of the total number of the parking spaces in the whole city. From the type, the parking spaces are mainly concentrated in residential areas, accounting for 57%; 147 thousands of public building type parking spaces account for 39 percent. The sum of the two types is more than 95% of the total amount.

As shown in table 1 and fig. 5, the severe and huge gap in parking space caused by the parking difficulty also causes many hidden troubles, such as blockage of fire passage, blockage of bicycle lane, etc., which may bring immeasurable loss to the safety of people's lives and properties. The invention aims to design a mechanical device to relieve or solve the problem of difficult parking in partial areas. Wherein, table 1 is a parking demand gauge.

TABLE 1

According to the knowledge, the six urban areas and the suburban areas, the living areas of the new cities, occupy the vacant spaces and the internal roads (not affecting fire protection), and the total number of freely parked vehicles is 63 million. If the parking places in the existing residential area are properly standardized, intensive three-dimensional parking facilities are built by means of flat-changing and vertical-setting, utilization of the remaining vacant land in the residential area, functional relief of vacated land and the like on the basis, and the contradiction of residential parking can be relieved by a certain increment. Therefore, the focus is focused on the sky parking structure, that is, how to set the scene and the prototype woolen used. When the holding amount of the automobile is larger than the planned parking amount, the problem of difficult parking is highlighted, so that the problem is more prominent when the planned parking area of the community or street is smaller.

Through research, parking spaces are not generally planned in communities built in Beijing before 2000 years, and for example, in Western regions in Beijing, as shown in Table 2 and FIG. 6, 645 communities are built in communities built in 1997 before 1997, and the buildings are tower buildings and plate buildings), while only 220 communities are built in 1997. Therefore, it is seen that old districts still occupy most of urban areas, and the problem of parking difficulty is caused by planning parts during construction, which becomes a pain point of the problem, so that designing old districts for designing prototypes and environments is one of the problems to be solved. Wherein, table 2 is a fault planning change table of the urban community.

TABLE 2

With the prototype, the existing products and technologies and related data are excavated, the characteristics of the existing small and medium-sized cells are firstly analyzed, and the following three reasons that the stereo garage in the existing market is difficult to apply to the stereo garage are summarized:

(a) the intensity of the building is as follows: building is relatively dense and cannot accommodate large-scale three-dimensional parking garage

Here a quantity "volume fraction" is introduced. The volume ratio is an important index for measuring the use strength of the construction land, and is the ratio of the total ground building area to the land area of a cell. Generally, the volume ratio of high-rise houses is not more than 5, the volume ratio of multi-rise houses is not more than 3, the green space ratio is not less than 30%, and generally, houses built before 2000 years are of multi-rise structures, so the volume ratio is about 3. Further visiting and investigation, the common inter-floor distance of the community is found to be 20-25 meters mostly. (this can be calculated from the volume fraction and the associated population data, this time in a walk-through fashion) this spacing is substantially equal to the height of the building, which also allows good daylighting for the residents of the community.

(b) Greening: the stereo garage occupies a large area and occupies the original greening area

As mentioned above, the degree of greening is also one of the important standards for building a small area, and certainly one of the basic guarantees for physical and mental health of the people, so that in such a small area, a large amount of open space is used for building green space and cultural entertainment facilities, especially on the non-unit door side of the residential building, which is also related to the lighting environment of the residential building. While the area for greening is eliminated, the area for parking is very limited due to planning problems.

(c) Human factor: some residents stay indoors for a long time and need to be taken into consideration

Residents are users and owners of the residential areas, so that the rights and interests of the residents are guaranteed to be paid attention to in all public design fields, the relative age group distribution of the residents of the residential areas is comprehensive, and the residents have retired old people and children, so the living habits of the residents are considered.

In summary, the conventional plot parking situation is shown in fig. 7 and 8, and the parking space design scheme is determined from two dimensions according to the present invention: the car owner dimension, the resident dimension, and hope final parking stall can enough let the car owner accomplish the parking safely, swiftly, conveniently on the basis that increases the parking stall, also can let resident's life not receive the influence.

The following describes a multistory parking facility access unit based on an old cell according to an embodiment of the present invention with reference to the accompanying drawings.

Fig. 9 is a schematic structural diagram of an old cell-based overhead access unit of a multistory parking garage according to an embodiment of the present invention.

As shown in fig. 9, the old cell-based sky parking elevation access unit 10 includes: top level rotation system 100, auxiliary starting system 200, lifting system 300, and electronic control system 400 (not specifically identified).

The top layer rotating system 100 includes a top layer rotating plate for placing top layer vehicles, so that when the top layer vehicles enter the garage and reach a first preset position, the top layer rear wheel baffle is started to fix the vehicles, and when the top layer vehicles leave the garage, the top layer rear wheel baffle is cancelled. The auxiliary starting system 200 includes a slide rail platform to assist the vehicle in parking and climbing a slope. The lifting system 300 is used for controlling the top layer rotating plate to ascend and the sliding rail platform to reach a second preset position when the bottom layer vehicle parks and enters the garage, controlling the top layer rotating plate to descend and the sliding rail platform to reach a third preset position after the bottom layer vehicle runs onto the sliding rail platform, and controlling the top layer rotating plate to ascend and the sliding rail platform to reach the second preset position when the bottom layer vehicle leaves the garage, so that the top layer rotating plate is controlled to descend and the sliding rail platform to reach the third preset position after the bottom layer vehicle runs off the sliding rail platform. The electronic control system 400 is used for controlling the top layer rotation system 100 and the lifting system 300 to work according to preset control signals so as to realize vehicle parking. The access unit 10 of the embodiment of the invention greatly improves the utilization efficiency of the parking space, shortens the parking time, effectively improves the use experience of users, and has the advantages of small construction amount, low cost, simplicity and easy realization.

It can be understood that the parking unit designed by the embodiment of the invention integrally consists of the following structures: top floor turning system 100, floor space, auxiliary starting system 200, lifting system 300, and electronic control system 400. A parking unit can park two vehicles on the top rotating plate and the bottom slope respectively. The system is of a semi-underground structure, the height of the top layer rotating plate is flush with the ground, and the rest structures are installed underground. Each of these sections will be further described separately below.

Further, in one embodiment of the present invention, the top level rotation system 100 further comprises: fixed pivot and top layer balancing weight.

Wherein, the both ends of fixed rotating shaft link firmly with ground respectively, and the bearing of fixed rotating shaft is connected with top layer commentaries on classics board to drive top layer commentaries on classics board and rotate around fixed rotating shaft. The top layer balancing weight is installed below the rotating plate on the rear side of the fixed rotating shaft and fixedly connected with the top layer rotating plate.

Specifically, as shown in fig. 10, the system 100 is composed of a fixed shaft, a top rotating plate (including a tire shield), and a top weight. The rotating mechanism is a driven part, and no main power is output at the rotating shaft.

Fixing the rotating shaft: the two ends of the shaft are fixedly connected with the ground, the bearing is connected with the bearing plate, the rotating shaft is fixed when rotating, the bearing drives the top layer rotating plate to rotate around the fixed shaft, and the rotating power is derived from a lifting system. For parking spaces parked side by side, the rotating shafts can be shared, so that the construction cost can be greatly reduced.

And (3) turning the top layer into a plate: the parking device is used for parking top vehicles, materials are formed by welding steel plates, the rotating plates are internally provided with hollow structures, and reinforcing steel bars are used for reinforcement. The tail end adopts an arc surface so as to be convenient for the slope matching of the bottom layer and ensure that the jolt of the top layer vehicle is small when the vehicle leaves the garage. Meanwhile, in order to prevent the driver from forgetting to pull the hand brake to cause the vehicle to slide backwards after the rotating plate rises, the tail end of the rotating plate is provided with a convex tire baffle, and the vehicle is prevented from driving backwards through physical obstruction.

As shown in fig. 11, top layer weight: install in the commentaries on classics board below of pivot rear side, link firmly with changeing the board, the purpose of design balancing weight is for alleviateing the burden of lifting system, and the clockwise moment (using the pivot as the fulcrum) that concrete effect for offsetting commentaries on classics board self gravity and bring saves electric power and the energy, simultaneously because itself has unnecessary cavity in the pivot below in the design of bottom space, consequently need not additionally excavate underground space for arranging the balancing weight.

Further, in one embodiment of the present invention, the lifting system 300 comprises: gear, rack and motor.

Wherein the gear is fixedly arranged. The rack is arc-shaped, is arranged on the gear and is fixedly connected with the top rotating plate so as to drive the top rotating plate to rotate around the fixed rotating shaft. The motor is a speed reduction motor, is fixed on the ground and is used for driving the gear to rotate so as to drive the rack to rotate.

Specifically, as shown in fig. 12, the system 300 is a power output mechanism, and is composed of a gear, a rack and a motor, the transmission structure is a gear-rack structure, the motor drives the gear to rotate, the center of the gear is fixed, and the rack rotates upward to meet the relative movement condition. The rack is fixedly connected with the bearing plate so as to drive the bearing plate to rotate upwards.

Gear: the standard part gear is adopted, and the gear rack mechanism is a key part for the entrance and exit of vehicles on the top layer, so that the load of the dangerous section of the gear is high, and the gear is required to be wear-resistant and not easy to damage under the low-speed rotation working condition, therefore, the embodiment of the invention can select high-quality medium-carbon steel or low-carbon steel, and the gear rack mechanism can be set by a person skilled in the art according to the actual condition without specific limitation. The gear is installed on gear motor, and the motor is fixed in ground, and the gear during operation only rotates and does not translate.

Rack: the arc-shaped rack is in an arc shape taking the center of the rotating shaft as the center of a circle, is matched with the gear, is made of high-quality medium carbon steel or low carbon steel and is fixedly connected with the top rotating plate, and the rack moves upwards/downwards during working to drive the rotating plate to rotate around the rotating shaft.

A motor: driving the gear to rotate.

Further, in an embodiment of the present invention, the access unit 10 of the embodiment of the present invention further includes: a bottom layer space. The bottom space is formed by the lower edge of the top rotating plate, the rear extension of the cavity and the slope, wherein the cavity is used for accommodating bottom vehicles, and the tail end of the slope is chamfered into a round angle.

Specifically, as shown in fig. 13, the bottom space is mainly formed by the lower edge of the top rotating plate, the cavity back extension and the slope. The primary purpose of the cavity is to accommodate the underlying vehicle. In order to ensure that all vehicles can safely enter a bottom layer vehicle, in the embodiment of the invention, a sport/Sport Utility Vehicle (SUV) with a larger size on the market is selected as a reference vehicle model, the vehicle model is abstracted into a basic model, the model can be ensured to be completely put in when a bottom layer cavity is designed, and the vehicle model of Enfenidi QX80 is taken as an example.

Slope: the shape of the slope is not a single slope, and considering that the bottom vehicle may interfere with the ground when leaving the garage, the end of the slope may be rounded, for example, the parameters may be as shown in fig. 14, of course, this is only one design parameter of the present invention, and those skilled in the art may set the parameters according to actual use requirements, and the embodiment of the present invention only uses fig. 14 as an example, and is not limited specifically herein.

Further, in an embodiment of the present invention, the auxiliary starting system 200 further includes: steel cable, guide rail, hauler, bottom balancing weight and pulley.

Among them, a wire rope and a guide rail. And the traction machine is used for dragging the steel cable to provide power for the sliding rail platform. And the bottom layer balancing weight is used for reducing the burden of the traction machine. The pulley is fixed on the slope near the outlet, and the steel cable is connected with the traction machine by passing through the pulley. The sliding rail platform is connected with a steel cable, the steel cable penetrates between the vehicle bottom and the sliding rail platform, the sliding rail platform comprises a tire support plate, rollers and a platform beam, the platform beam is connected with the steel cable, the platform beam is connected with the tire support plates on two sides, keys matched with the guide rails are arranged below the tire support plates, and the platform beam is used for pushing a bottom vehicle to drive to the ground until front wheels of the vehicle run to the ground.

Specifically, as shown in fig. 15, the system 200 is comprised of a wire rope, a slide rail platform, a guide rail, a hoist, a pulley, and a weight. Because the bottom layer vehicle stops on the slope, not all vehicles can climb the slope to start by means of own power, and meanwhile, the slope starting and the slope reversing are too high in technology for a driver, so that the time required for parking is prolonged in the meantime for the parking operation, and the auxiliary starting system 200 is designed in the embodiment of the invention.

Steel cable: drag slide rail platform and go up the slide, the steel cable is walked around behind the pulley and is connected with motor and balancing weight. The steel cable passes through the space between the vehicle bottom and the sliding rail platform and is connected with the platform.

The platform beam is connected with the tire support plates on the two sides, and the steel cable is connected with the platform beam. And keys matched with the guide rails are arranged below the tire carrier plate. When the bottom vehicle needs to go out of the garage, the platform pushes the vehicle until the front wheel of the vehicle drives to the ground, and the vehicle can start on a flat ground.

Guide rail: the guide rail is matched with the slide rail and arranged on the inclined plane, is made of metal, and lubricating oil needs to be coated on the guide rail when the guide rail is used.

A traction machine: power output of sliding rail platform, traction machine dragging steel cable

Pulley: the steel cable is connected with the traction machine by passing through the pulley which is fixed at the position close to the outlet of the slope

Bottom layer balancing weight: the bottom layer balancing weight is used for reducing the burden of a traction machine in the auxiliary starting system. The design of balancing weight has all had very mature application in many places, and the most typical application is the elevator, and according to the relevant theory of elevator promptly reality application, generally speaking the weight of balancing weight is about half full load weight, and to supplementary start-up system 200, full load weight is equivalent to pulling force on the steel cable that drags the platform needs when stopping and releasing the car for the bottom platform.

The theoretical calculation of the key numerical value in the embodiment of the present invention will be explained in detail below.

(a) Inclination of bottom slope

Theta is the inclination angle of the lower slope, and the theta can satisfy the following three conditions:

(1) the automobile cannot slide downwards after the hand brake is pulled up when the automobile is parked;

(2) when the automobile is parked, any part of the automobile body cannot interfere with the upper layer rotating platform;

(3) the bottom layer automobile can be started from a standstill and successfully climbs a flat slope.

Meanwhile, in order to make the construction amount as small as possible, the gradient should be made as large as possible.

The static condition of the automobile is tan theta < mu, mu is the static friction coefficient (adhesion coefficient) between a tire and the ground, and the value of mu is generally between 0.65 and 0.8 through data query and experiment, and theta <33.02 degrees ① is obtained by taking mu as 0.65.

To satisfy the condition (2), if a natural coordinate system as shown in fig. 17 is established, it is necessary to satisfy the ordinate y < h of any part of the vehicle, obviously, the thickness of the part of the vehicle at the vehicle head will be reduced, and it can be considered that the plane on the vehicle head is parallel to the ground, and then: the fact that the vehicle does not interfere with the upper baffle is equivalent to: the two points A, B of the cart do not interfere with the baffle.

Wherein Δ L is compared to L₁And L₂Is a small quantity, can be ignored, so the coordinate (x) of point A_A，y_A) B point coordinate (x)_B，y_B)；y_A＝L₂sinθ+h₂cosθ，y_B＝L₁sinθ+h₁cosθ。

In order to ensure sufficient safety of data, the embodiment of the invention selects the Jumbo in the household vehicle: an SUV.

The inquired data: l is₁Taking 5.3m, L₂Taking 3.0m, h₁Taking 1.3m, h₂Taking 1.95 m;

max{L₂sinθ+h₂cosθ，L₁sinθ+h₁cosθ}<h；

taking h as 3.8 to obtain the product with theta less than 30.48 degrees ②;

to make a margin, the bottom layer region of h <1m is designed to be a circular arc chamfer with a chamfer radius of 5m to ensure no interference, and θ is taken to be 30 ° from condition ①②.

Regarding condition 3), at the time of starting the vehicle, the self gravity component and the maximum static friction force are overcome, and are analyzed by the force:

by data inquiry, take G26000N, F_{Traction max}＝17000N，μ＝0.014，

Obtaining: f + Gsin θ 13315N, clearly greater than F_{Traction max}Thus: the bottom layer automobile can not climb by independently depending on power, and in order to solve the problem of climbing of the bottom layer automobile, the auxiliary starting system 200 is designed.

(b) Top tier swing system 100

Assuming that the center of gravity of the automobile with the upper baffle is located at the position of the baffle, the stress of a single tooth of the gear is as follows:

G₁for vehicle weight, G₂Is the weight of the baffle;

G₂＝V_boardρ_Steelg, wherein V_Board＝a_Boardb_Boardd_Board＝6.4·3·0.1＝1.92m^3，ρ_Steel＝7.85×10³kg/m³；

Substituting to obtain: g₂＝1.4771×10⁵N，

Meanwhile, if the vehicle weight is 26000N, P is 8.659 × 10⁴N，

Torque calculation for the motor:

wherein M is motor torque, R is gear radius, P is total weight of vehicle and lifting system, P is 30000N, R is 0.5M,

obtaining: m is 7500N · M and the gear radius is 0.5M, so the gear section stress F is 15000N;

thus, the torque required by the electric motor to ensure sufficient torque to lift the system is 1.2 × 10⁴The gear specification selection needs to meet the requirement that the upper limit of stress is more than or equal to 2.5 multiplied by 10⁴Now, the required rotation speed of the motor is calculated:

wherein, L is 6.45m, R is 0.5m, and the following products are obtained: n is 13 r/min.

(c) Assisted Start System 200 calculation

As shown in fig. 18, the auxiliary starting system 200 uses a motor to drive a steel cable to pull the slide rail platform, the entire vehicle and the slide rail platform are pulled to the ground along the guide rail by the steel cable, and the resistance applied to the vehicle and the slide rail platform is divided into two parts, namely, the friction between the slide rail platform and the slide rail and the resistance applied to the front tire of the vehicle and the slope. Force analysis is as follows (assuming the vehicle centroid is located at the centroid):

when calculating, P is 18000N, α is 30 mu₁＝0.6，μ₂0.1; obtaining: t14455.96, i.e. the cable tension needs to reach this value, the radius of the cable take-up axis of the motor cable is 0.7 m, and the torque required by the motor is 1.011 x 10⁴N.m. The rotational speed of the motor is calculated as follows:

in the formula, s is the distance that slide rail platform needs the motion, and t is total time, and s is 7m, and t is 5s, gets: v is 1.4 m/s;

taking 0.7 m as R: n is 19 r/min.

Therefore, the rotation speed of the motor should be 19 rpm, the motor needs to have a speed reducer, and if a gear with the R being 1.02 m is used, the auxiliary starting system 200 and the lifting system 300 can share one motor.

The dynamic process and parking unit descriptions of embodiments of the present invention are further described below.

Further, in an embodiment of the present invention, the access unit 10 of the embodiment of the present invention further includes: a display device. The display device is used for displaying parking quantity information of the pitching type access unit and position information of the corresponding vehicle.

It can be understood that the user can find the idle garage to park according to the parking state of the parking garage which is known by the display device quickly and accurately, so that the use experience of the user can be effectively improved, and the parking efficiency is effectively improved.

For example, in practice, especially when the system is applied to cell design and infrastructure, in order to facilitate operation of the present embodiment, a remote control system is designed, and each parking unit has a control panel, as shown in fig. 19 (only basic function keys and indicator lamps are shown).

The using and operating method specifically comprises the following steps:

A. top vehicle parking and warehousing process

The default initial state is that the bearing plate rotates to the height of the ground, namely the state 1, and the parking and warehousing process is as follows:

(1) a driver drives a vehicle to the bearing plate at a low speed from the ground and marks a parking space;

(2) starting a hand brake;

(3) after the driver leaves the vehicle, a key for starting a top rear wheel baffle is pressed (or remotely controlled) on a control panel beside the parking space, and the driver waits for the indicator lamp to be turned on;

(4) after the rear wheel baffle is in place, the driver can leave after the parking is finished.

Note that:

(1) recommending reversing and warehousing;

(2) the speed should be slowed down when backing the car, and the area of the bearing plate cannot be exceeded.

B. Top-level vehicle starting and leaving process

At this time, the initial state should be state 2, and the starting ex-warehouse process is as follows:

(1) the driver presses (or remotely controls) a key for canceling the rear wheel baffle on the top layer on the control panel;

(2) waiting for the baffle indicator lamp to be turned off;

(3) a driver enters the vehicle, cancels the hand brake and starts the vehicle;

(4) driving slowly and leaving the parking space;

(5) and finishing the warehouse-out.

Note that: the speed should be slowed down at start-up, especially when the vehicle is driven to the joint of the bearing plate and the ground, otherwise the bumpy feeling is obvious.

C. Parking and warehousing of bottom vehicles

At this time, the initial state should be 1 or 2, and the parking and warehousing process is as follows:

(1) if the initial state is 2, firstly, confirming that the baffle indicating lamp is in a lighting state;

(2) the driver remotely controls (or presses) the top layer ascending key;

(3) after the bearing plate rotates and the sliding rail platform is in place, the indicating lamp is turned on;

(4) the driver drives the vehicle to run in a reverse mode until the rear wheels run onto the sliding rail platform;

(5) when a driver leaves the vehicle and closes the vehicle door, the top layer descending key is remotely controlled (or on a control panel) to be pressed down, and then the sliding rail platform automatically drives the vehicle to descend to the bottom layer space;

(6) after the bearing plate rotates and the sliding rail platform descends in place, the indicating lamp is turned on;

(7) the driver starts the electronic hand brake;

(8) and stopping and warehousing.

Note that:

(1) when the vehicle slides on the slide rail, the hand brake can not be pulled up;

(2) the vehicle must be driven in a reverse direction;

(3) it is important to wait for the next operation to be performed after the indicator light is turned on.

D. Bottom vehicle starting and leaving process

At this time, the initial state should be 3 or 4, wherein the state 3 is that there is no vehicle on the top floor, there is a vehicle on the bottom floor, and the state 4 is that there are vehicles on both the top floor and the bottom floor, and the starting warehouse-out process is as follows:

(1) the driver remotely controls (or presses) the top layer ascending key;

(2) waiting for the bearing plate and the sliding rail platform to rotate, driving the vehicle to the ground by the sliding rail platform, and lighting the indicator light;

(3) a driver enters the vehicle, the hand brake is closed, and the vehicle driving slide rail platform is started;

(4) remotely (or on a control panel) pressing a 'top-level down' button;

(5) the driver can directly drive the vehicle to leave without waiting for the indicator light to be turned on, and the vehicle is taken out of the garage.

Note that: and 4, the driver can enter the vehicle after waiting for the sliding rail platform to stop the displacement indicator lamp to be turned on.

The access unit of the embodiment of the present invention is further described by way of specific embodiments below.

The mechanism of the multi-unit parallel state is simplified, and as shown in fig. 20, the vehicle parking is roughly divided into two types, namely horizontal parking and vertical parking. The horizontal parking form is similar to the parallel connection in the circuit, and if the parking unit is applied to the horizontal parking space, the parking unit is called as a multi-unit parallel connection state. In designing the structure, the embodiment of the present invention has considered the structural simplification in the state of the multiple units being connected in parallel, and reduces the overall cost and the amount of construction by sharing the structure, integrating the design, and the like. The following is a specific simplification.

(a) Sharing of fixed rotating shaft

In design, the embodiment of the invention adopts a mode that the rotating shaft of the bearing is static, but the rotating shaft of the bearing is not static, namely, the fixed rotating shaft can be shared. For a row of parallel parking spaces, the adjacent fixed short rotating shafts can use one communicated shaft without being disconnected, so that the processing amount and the cost are reduced.

(b) Shared use of speed reducing motor

When the parking spaces are connected in parallel, two adjacent parking units can use the same speed reducing motor, and the power of the motor is controlled to be transmitted to which rack through the axial movement of the gear. It should be noted that, in theory, the method can make the entire row of parking spaces share one reducing motor, but this structure can only ensure that the top rotating plate of one parking space in one row is lifted each time, and in consideration of reality, especially during peak hours of going to and from work, the requirement that multiple vehicles in one row of parking spaces get in and out simultaneously often occurs, and if one row of parking spaces share one reducing motor, the phenomenon of queuing may occur, which is obviously contrary to the concept of designing parking spaces of the embodiment of the present invention. If only two units share one motor, even if vehicles in two parking spaces need to enter and exit, the waiting time is only about 10 seconds at most, and in addition, the probability of simultaneous entering and exiting of adjacent parking spaces is small, and the total waiting time is expected to be negligible.

(c) Communication of the underlying spaces

When the underground pipeline of the residential area is simple, a communicated columnar cavity can be dug instead of each separated small cavity when the parking unit is built, so that the construction is beneficial from the aspects of construction complexity and cost.

(d) Sharing of peripheral facilities

Due to the infrastructure, in addition to considering the parking structure itself, it is also necessary to consider its impact on the facility of the cell. Because the unit of the embodiment of the invention has an upper layer and a lower layer, the problem of drainage needs to be considered emphatically, and in practical use, drainage grooves are designed at each parking space, and when the parking spaces are placed in parallel, the drainage grooves can be shared.

In addition, because this parking structure needs to use electric power as the energy source, the multiunit uses and is favorable to the arrangement of electric wire. Similar peripheral facilities may in principle be shared.

The electronic control system 400, i.e., the electro-mechanical combination control system, will be further described below.

Further, in one embodiment of the present invention, the access unit 10 implemented by the present invention further includes: a standby power supply device. The standby power supply device is used as a standby power supply when the pitching type access unit has power failure.

Further, in one embodiment of the present invention, the access unit 10 implemented by the present invention further includes: and an alarm device. The alarm device is used for generating an alarm signal and giving an alarm prompt when the infrared sensor at the tail end of the top layer rotating plate is blocked.

Further, in an embodiment of the present invention, the electronic control system 400 is further configured to receive an alarm signal, a forced stop remote control signal, and a manual emergency switch signal, so as to stop the movement of the top layer rotating system and the lifting system according to any one of the alarm signal, the forced stop remote control signal, and the manual emergency switch signal.

Specifically, the power components to be controlled in the system 400 mainly include a main rotating shaft and an auxiliary lifting slide rail, and the control signals are remote control signals of a user, sensor signals of an automobile entering and exiting a garage, and a manual emergency switch.

The main rotating shaft is driven by a speed reducing motor and is used for driving the bearing plate of the upper garage to lift and descend, the bearing plate of the lower garage is lifted slowly when the lower garage needs to enter and exit, and the bearing plate of the upper garage automatically or manually descends to the original position after entering and exiting the garage. The lifting and lowering process may last for more than thirty seconds, and this process uses closed loop control. The conditions for stopping the descending process are as follows: the pressure sensor at the end position receives a signal that the bearing plate reaches the lowest position, and indicates that the descending process is finished, and the motor stops rotating; the infrared sensor at the tail end of the bearing plate is blocked, so that the situation that a vehicle in a lower garage does not completely leave a parking space on a descending path possibly is shown, the motor is prevented from being stopped immediately and the existing position is kept; or the motor is also controlled to stop when a remote control signal and a manual emergency switch signal for forced stop are received. Except for receiving the instruction signal, the initial condition of the descending process is that after the infrared sensor detects that the vehicle enters or leaves the garage, the descending process is automatically started for a short time, and the homing is automatically completed under the condition that the user forgets to press the homing. And in the rising process, the problem of collision of the vehicle is not considered, open-loop control is performed, and the motor is started to rotate by a fixed angle and then stops.

The auxiliary lifting slide rail is driven by a motor to drive a movable support on the chain to be in contact with the front end of the automobile in the lower garage, so that auxiliary power is provided for the automobile in the lower garage to finish the action of getting out of the garage and putting in the garage. The auxiliary lifting slide rail is started to be in synchronization with the main rotating shaft in a default mode, the process that the automobile enters and exits the garage is carried out in the lifting state of the main rotating shaft, and at the moment, the motor automatically starts to work to provide auxiliary power for the automobile to ascend the slope or generate proper speed reduction in the descending process; when necessary, the start and stop of the slide rail can be manually controlled.

The transmission of remote control signal uses bluetooth or WIFI, and the main control board even has bluetooth module or the WIFI module of receiving and sending the signal. A user only needs to install a remote control program client and establish connection with a corresponding control system on the parking space of the user, and then the user can directly remotely control the lifting of the parking device. In the embodiment of the invention, a set of management system is established, accounts can be set for users, each account is matched with the own parking space in the system, and each user can automatically establish connection with the own parking space after logging in and can only remotely control the own parking space.

Note that, when using a sky-parking-lot overhead access unit based on an old cell, attention is paid to the following points:

(a) has higher technical requirement on backing of the driver

Because the back wheels are required to stop on the sliding rail platform when the bottom layer vehicle backs up and enters the garage, the operation is difficult for a driver who is not in the right skill. This can be objectively solved by convincing old drivers with high driving skills to park on the bottom floor, but few people in reality are willing to park on the bottom floor, and the difficulty and time of parking on the bottom floor are inferior to those of parking on the top floor.

(b) Require the bottom layer vehicle to be equipped with an electronic hand brake

The parking process of the parking space at the bottom layer is that a driver parks the rear wheels on the sliding rail platform, then the sliding rail platform carries the automobile and puts the automobile to the parking space, and the driver does not need to come underground, so that the driver is required to be provided with the electronic hand brake, and otherwise, the driver does not have the opportunity to pull the hand brake. According to market research, most of the current popular and new cars are provided with electronic hand brakes, but old cars only provided with manual hand brakes cannot be ignored, and the cars have a long time to be scrapped, so that the demand is also important. A temporary solution is to park these vehicles without electronic handbrake on the upper floor.

(c) Require that the underground piping of the community not be overly complex

It was also mentioned before in the project application above that if the cell underground piping is too complex to be re-routed, then re-construction can only be abandoned. This is due to the quality of life of the inhabitants, and is also a common problem for all semi-underground structures, whether they are vertically elevated or in the context of a pitch-and-dive parking unit, as long as the underground space is utilized.

(d) Some four-wheel driven vehicles cannot be parked on the bottom floor

Based on the design, the rotation of the front wheels and the rear wheels is not synchronous when the bottom layer vehicle enters or exits the garage, so that the four-wheel drive vehicle cannot be parked on the bottom layer. The present solution is the same as the second point, leaving these vehicles parked on the top floor, and after all four-wheel drive domestic vehicles are still a minority in the current car market.

Further, the implementation effect of the embodiment of the present invention is shown in fig. 21, 22 and 23, and has the following advantages:

(a) short parking time

Compared with the existing vertical lifting type stereoscopic parking space in the market, the pitch type parking unit provided by the embodiment of the invention has shorter time. For top-level vehicles, the time spent parking is the same as for ordinary ground parking spaces; for the bottom layer vehicles, the garage only needs 5-7 seconds, and the vertical lifting three-dimensional parking space needs 25 seconds. The reason for this time difference is mainly that the structure adopts a rotary type opening and closing, the rotation angle is 30 degrees, and the rotation angular speed is

The vertical lifting adopts a displacement mode, the lifting height is 2.5 meters, and the lifting speed is 10 cm/s.

Although only 20 seconds are seemingly saved, the subjective feeling of 20 seconds is very great for office workers and other people who have a need for a more urgent trip. For car owners in this dimension, they certainly want to stop as soon as possible, so car owners would prefer the structure of the embodiments of the present invention rather than the hydraulic vertical lift car on the market.

(b) Greatly improves the space utilization efficiency of the parking space

To better characterize the space utilization of parking spaces, define

And d is the linearity of the parking spaces, N is the number of the parking spaces, and the smaller the numerical value of epsilon is, the smaller the length required by one parking space in a unit is, and the larger the space utilization rate is. To calculate epsilon of parking unit, it needs to be discussed in different cases, and the existing parking space arrangement is roughly divided into two types as mentioned before: horizontal parking and vertical parking.

First, horizontal parking, as shown in fig. 24, is abstracted into the following models:

the calculation of horizontal parking is simpler, does not change in width, and it is compared with ordinary parking stall to change, and the parking unit will be 1.8 meters long, can park two vehicles every 7.8 meters, and epsilon 3.9.

The vertical parking is as shown in fig. 25, and is abstracted into a lower right model:

the length of the vertical parking needs to be considered a lot, and because the parking has a rotary motion and an auxiliary starting system, when the bottom vehicle is out of the garage, a sliding rail platform of the auxiliary starting system can push the vehicle to go up along a slope until a front wheel of the vehicle reaches the ground level, and the vehicle needs to turn to go out of the garage, so that a distance of 3.46 meters needs to be reserved at the front end of a parking space, and the distance of 3.46 meters is about two thirds of a vehicle body. As a result, epsilon is 4.73,

for a typical parking space, the length is 6-6.5 meters, N is 1, and thus e is 6-6.5. Therefore, the space utilization rate of the pitching type parking unit is due to the common parking space no matter the horizontal type parking space or the vertical type parking space is found.

(c) The cost is low

The existing three-dimensional parking units on the market mostly adopt a hydraulic rod mode to carry out vertical lifting, and the manufacturing and maintenance cost of a hydraulic system is higher than that of a motor driving mode. In the aspect of fixed cost, the unit price of the hydraulic system for parking is about 4000 yuan, and the later maintenance cost is about 1000 yuan per year; the unit price of the speed reducing motor for parking is 3000-4000 yuan, two speed reducing motors are needed for one parking space, the two units share one motor, and the later maintenance cost is 500 yuan per year. And (4) comprehensively calculating, wherein the power cost of each parking space of the pitch-up parking unit is 2000 yuan, and the power of the vertical lifting parking structure is 2500 yuan. Therefore, the cost of the rotary power output driven by the motor is lower.

(d) The construction amount is small

The same is a semi-underground structure, the vertical lifting structure needs to dig a cubic space about 36 cubic meters underground, and the pitch parking unit only needs to dig a triangle-like structure, and the space of the motor is about 28 cubic meters. Therefore, during specific construction, the construction amount required by the pitching type parking unit is smaller than that of the common hydraulic type lifting three-dimensional parking space.

(e) Has little influence on residents

From the dimension of residents, the biggest defect of the common three-dimensional parking garage is that the lives of the residents are greatly influenced. The building interval of the medium and small residential areas is small, and meanwhile, the space left for parking is not as spacious as that of a large residential area, so that the lighting of residents in the first floor or even the third floor can be influenced if a common three-dimensional parking garage on the market is used. The height of a common three-dimensional parking garage is 2.5, and the common three-dimensional parking garage can just cover the window of a user on the first floor. In addition, the greening area of residential areas has strict requirements, and the space occupied by the three-dimensional parking garage is large, so that greening planting is not facilitated. In short, if a vote of 'whether to use a stereo parking garage' is held once for an old cell, most residents will object to opinions except that few high-rise residents probably represent support, and therefore infrastructure cannot be performed.

The pitch-up parking unit 10 according to the embodiment of the present invention solves the problem well, and since it has a rotary structure and a maximum rotation angle of only 30 degrees, the lighting of the residents in the first floor is not affected at all, as shown in fig. 26, and the top floor is in the position shown in the figure for only about 20 seconds each time the bottom floor vehicle is taken out of the garage, the lighting of the residents is minimized.

(f) The driver can finish parking without entering the bottom layer

For the car owner of the bottom car, the driver can get off after parking the rear wheel at the auxiliary starting platform, and the later operation is automatically completed by the mechanism, so that the car owner is simple and convenient, friendly to the driver and free from getting off to the bottom.

The old cell based sky park tilt access unit project application will be further described below.

In order to meet the actual requirements, the embodiment of the invention can carry out certain reconstruction on the parking unit and certain reconstruction on the cell. The method comprises the following specific steps:

(a) pipe arrangement

Since there are complex and dense pipe arrangements under the district, such as utility, drainage pipes, gas pipes, electric wires, network cables, etc., which inevitably have unpredictable results from the digger, it is necessary to obtain drawings of the pipe arrangements under the district before the construction, and to bypass the pipes or reroute the pipes to gaps between parking spaces during the construction of the parking unit. If the difficulty of pipeline reconstruction is too great, the plan for searching other places can only be abandoned, because if the life of the residents is influenced by increasing the parking space, the benefits of the whole residents are not paid, and the design concept of the embodiment of the invention is also violated.

(b) Energy supply

The power source of the pitch-up parking unit is electric power, and a series of devices such as an electric motor and an electric control system need to be operated by the electric power. The embodiment of the invention has two sets of schemes for residents to choose, one is that a branch is directly branched from a main electric wire to supply to a speed reducing motor and a traction machine, so that all users can share the electric charge consumed by the parking device; the second scheme is that the storage battery is used for supplying power to the motor, a vehicle owner recovers the electric charge of the storage battery, and the storage battery is maintained and charged by a property company. And finally, selecting which scheme is decided by the cell residence committee.

(c) Maintenance facility

The working conditions under natural conditions are definitely worse than those in a laboratory, so that maintenance facilities need to be added to ensure that the mechanism can be opened and closed smoothly.

First is the drainage facility. Since the underground structure is exposed for about 20 seconds when the top rotary plate is lifted, if precipitation, snow fall and the like exist in the weather, the accumulated water can seep into the bottom parking space. Consequently can utilize the slope simultaneously at bottom parking stall both sides design tortoise back of the body shape water drainage tank, let the rainwater can arrive the parking stall minimum smoothly, at minimum division drainage tank, be connected to district drainage house steward, just so solved the drainage problem.

Secondly, lubricating facilities are arranged, in order to ensure that key transmission parts such as pulleys, steel cables, guide rails and gears can work smoothly, a lubricating oil channel structure is added, and when the lubricating oil device is actually used, lubricating oil is added periodically by property personnel or special technical personnel, so that the good state of the parts is ensured.

And finally, the parking unit belongs to community infrastructure and can be frequently used, so that a self-locking mechanism needs to be added, the structure is locked by the self-locking mechanism after the top layer rotating plate reaches the top layer position, the motor does not bear the gravity of the vehicle and the rotating plate, and the service life of the motor can be prolonged.

(d) Spare power source

The embodiment of the invention uses electric power as a unique power source, so that when a community has power failure, the bottom layer vehicles cannot enter or exit the garage. In order to solve the potential risk, a standby electric box is provided, when the main circuit is disconnected, the standby power supply can be manually switched to supply power temporarily, and a switching button is arranged on a control panel. When the circuit recovers, the main circuit automatically charges the standby power supply when the power supply to the motor is not provided, and the electric quantity is still sufficient when the next accident occurs.

In summary, (a) the embodiment of the present invention employs a rotary three-dimensional parking unit, and the bottom space employs a slope type. The pitching type parking unit is a rotary type three-dimensional parking unit instead of a translation type three-dimensional parking unit, and meanwhile, as the top layer adopts a rotary type, the bottom space does not dig a whole cubic space at the bottom of the ground like other structures, but adopts a structure of parking on a slope.

(b) The embodiment of the invention utilizes a motor and a gear rack structure as a transmission mechanism. The parking unit adopts a structure that a motor drives a gear rack to realize transmission, and almost all the parking units use a hydraulic system as a transmission mechanism. Because the embodiment of the invention adopts the motor transmission scheme, firstly, the time consumed by parking is greatly reduced, and secondly, when multiple units are used together, certain mechanism simplification can be carried out aiming at the use of the motor, for example, one motor is shared by multiple units, and the like, thereby achieving the purposes of reducing the cost and reducing the construction amount.

(c) The method is based on the old community, and design consideration is carried out from two dimensions of a vehicle owner and residents. Parking units are designed based on old cells. The old cell is not only limited to old in age, but the parking unit is suitable for any cell with small size and compact space. The design is carried out by taking the condition as the background, the acting point is small and specific, and the considered situation is more detailed, so that the requirements of old cell users can be better met. In addition, the traditional parking structure only considers factors such as parking efficiency from the perspective of a vehicle owner, however, the embodiment of the invention also brings factors in the residential area into the design consideration range, and reduces the influence of a parking mechanism on residents in a building.

Further, when the underground parking device is applied to engineering, the application place of the underground parking device designed by the embodiment of the invention comprises the construction of small and medium-sized built communities and old communities needing to modify parking spaces due to the problem of insufficient parking spaces. For the application scene of parking stall transformation, the demand point lies in that the parking area size that can park between district's overall arrangement and the building can't change, and the design that utilizes underground parking space vertically layering can increase land utilization in this environment, and the parking equipment of unitization also can be according to local conditions simultaneously, lays reasonable overall arrangement to local space. In the engineering application of the parking spaces in the old community, the embodiment of the invention can consider more interference to the existing surrounding building facilities after construction, and the layout of the parking units considers the reserved space and the turning space of the road and does not damage the surrounding environment as much as possible.

Although the structure of the embodiment of the present invention is designed based on old cells, it is undeniable that in a three-four-wire city, many cells are newly built but there is not enough space to use an underground parking garage or a large three-dimensional parking space, so the parking unit of the embodiment of the present invention is also applicable to small and medium-sized new/built cells. For the application scene of newly-built small and medium-sized districts, the demand point is that the small and medium-sized districts are not suitable for building a unified parking lot sometimes, and small and fine parking units can meet pins at the moment, so that enough parking spaces are provided for the districts. In addition, for the newly-built small and medium-sized cells, the step of reconstructing and rearranging pipelines can be avoided, and the lines can bypass parking spaces in the prior layout.

In addition, the parking device designed by the embodiment of the invention can realize the parking layout with higher soil utilization rate in the cells with smaller inter-building distance, improve the problem of difficult parking, and hopefully ensure that the underground parking device has a better and more complete security system, as shown in fig. 27, and lower construction cost.

(a) Management intelligence

The embodiment of the invention networks all parking units, and accesses the community property management system for the community with the requirement, so that the management efficiency of a larger community and the community with high management requirement can be improved, the management cost is reduced, and a community manager can monitor the state of the parking device without running between buildings.

The user also needs a separate system for management, and the user can establish an account in the system and correspondingly connect with the parking space of the user. And the system can also be combined with new artificial intelligence safety technologies such as fingerprint identification, face identification and the like, so as to provide accurate, effective and convenient security service for users.

(b) Temporary parking system

In life, the parking space is often stopped on the parking space of other people when people visit and visit friends, the original car owner returns to a cell and finds that the parking space is occupied, and only the driver of the temporary car can be contacted to interrupt the activity to move the car, and if the parking unit is introduced into the cell, the process becomes more complicated. Therefore, as shown in fig. 28, it is desirable to introduce a decision system in the embodiment of the present invention to help the temporary vehicle identify which parking spaces are available for parking, and the parking space that is most suitable for the temporary vehicle is automatically provided by the system through calculation by inputting the time duration (e.g. one hour for parking at the shortest, three hours for parking at the maximum) of the parking space expected by the vehicle owner and the floor number of the target floor.

In order to solve the problem, the embodiment of the invention needs to introduce a machine learning algorithm, and a parking space information network is formed by collecting the usual travel habit of the vehicle owner and considering the travel plan autonomously input by the vehicle owner, so that the parking spaces can be used at a time.

(c) Automation of parking process

As shown in fig. 29, in the embodiment of the present invention, in combination with the networking and intelligent parking technologies of the vehicle, a sensor, a signal transmitter, and the like may be installed on the parking unit, and linked with the vehicle-mounted intelligent driving system to complete the light guidance or the sound wave guidance of the back car after signal docking, so that no manual operation is required during the whole parking process, and the method is simple and convenient.

According to the semi-underground rotary type three-dimensional parking structure which does not occupy too high space, provided by the embodiment of the invention, equipment can be miniaturized, plane space is not excessively occupied, tree influence is effectively avoided, on the basis of increasing parking spaces, a user can complete parking safely, quickly and conveniently, and the life of residents is not influenced, so that the space utilization efficiency of the parking spaces is greatly improved, the parking time is shortened, the use experience of the user is effectively improved, the construction amount is small, the cost is low, and the rotary type three-dimensional parking structure is simple and easy to realize.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
