Description

Technical Field

[0001] The invention relates to a three-dimensional parking garage and a method for parking, entering, and taking a car out of the garage. Background Art

[0002] The parking problem is a static traffic problem that arises in urban development. Static traffic is a traffic form that exists relative to dynamic traffic. The two are interrelated and affect each other. For vehicles in the city, they are dynamic when driving and static when parked. Parking facilities are the main content of urban static traffic. With the increase of various vehicles in the city, the demand for parking facilities is also increasing. If the balance between the two is lost, parking facilities will be unable to meet the demand for parking space for the increase in vehicles, and the problem of parking difficulties will arise.

[0003] A multi-story parking garage is a mechanical device used to store and retrieve the maximum number of vehicles. Currently, rectangular coordinate square multi-story parking garages and vertical circulation multi-story parking garages are mostly used, but they all have problems such as complex movement, low space utilization, and long storage and retrieval time. In addition, the existing multi-story parking garages have unreasonable structural design and layout, resulting in large area, high cost, limited capacity, and high energy consumption, which cannot meet the increasingly prominent static traffic problems. Summary of the invention

[0004] In view of the above problems, the present invention provides a three-dimensional parking garage and a method for parking in and out of the garage, which occupies a small area, has low cost, large capacity and low energy consumption, and can meet the increasingly prominent static traffic problems.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A three-dimensional parking garage comprises a three-dimensional garage frame and a vertical lifting mechanism, and also comprises a horizontal rotation shifting mechanism, a vehicle carrying unit and a plurality of arc parking spaces for placing vehicles;

[0007] The garage three-dimensional rack comprises multiple layers of non-enclosed incomplete circular arc tracks with the same structure from top to bottom;

[0008] The vehicle-carrying unit is moved up and down by a vertical lifting mechanism, and the vehicle-carrying unit and the incomplete circular arc track on the layer form a complete circular ring track;

[0009] The vehicle-carrying unit is connected to the horizontal rotating displacement mechanism, and each arc parking space is connected to the vehicle-carrying unit in a slidable manner. Driven by the horizontal rotating displacement mechanism, the arc parking space moves along the circular track.

[0010] Preferably, the incomplete circular arc track is a double-layer structure.

[0011] Preferably, the garage stereoscopic rack also includes an upper top plate, a lower base, pillars, a fixed arc track support frame and an incomplete circular arc track support plate, the pillars are arranged between the upper top plate and the lower base, each layer of incomplete circular arc track is arranged on the incomplete circular arc track support plate, and the incomplete circular arc track support plate is installed on each layer of fixed arc track support frame.

[0012] Preferably, the arc parking space comprises an arc friction arm, a bracket, and a slidable device;

[0013] The bracket is provided with a lane for placing vehicles, the bracket is slidably connected with the vehicle-carrying unit through a slidable device, and the bracket is connected with a horizontal rotation displacement mechanism through an arc friction arm.

[0014] Preferably, the vehicle carrying unit comprises an upper slideway support plate, a lower slideway support plate, a connecting bracket and two slideways, the upper slideway support plate and the lower slideway support plate are connected via the connecting bracket, and the two slideways are arranged in parallel on the outer sides of the upper slideway support plate and the lower slideway support plate.

[0015] The present invention also provides a parking method for a three-dimensional parking garage, comprising the following steps:

[0016] When parking, after the vehicle is identified by swiping the card, it drives into the arc parking space on the first floor and stops after touching the mechanical or electrical limit device on the lane. The control system identifies the optimal parking position through the algorithm, so that the lifting drive device drives the vehicle-carrying unit to move up and change floors. When it reaches the optimal parking floor, the lifting drive device stops and self-locks. Then, the rotary drive device drives the friction wheel to rotate, and drives the arc parking space on the vehicle-carrying unit to rotate circumferentially through the friction transmission between the circular arc friction belt arm until the circular arc parking space reaches the optimal parking position, and moves the vacant circular arc parking space to the vehicle-carrying unit, ensuring that the circular arc parking space can be moved into place under the detection of the proximity sensor. After that, the lifting drive device moves downward to move the vehicle-carrying unit to the first-floor storage position, waits for the next parking to arrive, and repeats the above steps.

[0017] The present invention also provides a parking method for a three-dimensional parking garage, comprising the following steps:

[0018] The vehicle drives into the arc parking space of the vehicle loading unit;

[0019] The control system searches for the nearest free arc parking space and determines the parking path;

[0020] The lifting drive device drives the vehicle-carrying unit to move upward and change floors through the vertical lifting mechanism until it reaches the parking floor where the nearest arc parking space is located;

[0021] The rotary drive device drives the arc parking space to rotate in a rotational manner with the shortest path through the horizontal rotary shifting mechanism until the vacant arc parking space moves to the vehicle loading unit, and parking is completed.

[0022] Furthermore, when a vehicle enters the arc parking space of the vehicle loading unit, the control system starts to search for the nearest vacant arc parking space only after the vehicle touches the mechanical or electrical limit device on the lane.

[0023] Furthermore, the control system uses a self-optimization algorithm to find the nearest free arc parking space.

[0024] Furthermore, when the vacant arc parking space is moved onto the vehicle-carrying unit, the lifting drive device drives the vehicle-carrying unit back to the initial storage position through the vertical lifting mechanism.

[0025] The present invention also discloses a method for taking a car out of a three-dimensional parking garage, comprising the following steps:

[0026] The control system searches for the parking location of the vehicle and determines the route to pick up the vehicle based on the owner's information;

[0027] The lifting drive device drives the vehicle-carrying unit to move upward and change floors through the vertical lifting mechanism until it reaches the parking floor where the vehicle to be picked up is located;

[0028] The rotary drive device drives the arc parking space to rotate in a rotational manner with the shortest path through the horizontal rotary shifting mechanism until the arc parking space carrying the vehicle to be picked up is moved to the vehicle carrying unit;

[0029] The lifting drive device drives the vehicle-carrying unit to descend to the initial storage position through the vertical lifting mechanism, and the vehicle retrieval is completed.

[0030] The beneficial effects of the present invention are: a cylindrical rotary structure is adopted, and the vehicle storage and retrieval is realized by using two kinds of movements, namely vertical lifting and horizontal rotation and displacement. Only one movable exchange parking space (i.e., the vehicle carrying unit 2) that can be lifted and lowered forms a complete circular ring track with the incomplete circular arc track of each layer. The horizontal rotation and displacement parking of each layer and each parking space can be realized by driving with a rotary drive device. The structural design is ingenious, the capacity is large, the energy consumption is low, the cost is low, the parking and retrieval action is simple, the floor space is small, and the space utilization rate is high. Moreover, it can be expanded into a medium-sized and large parking garage along the vertical axis and the horizontal radial direction, and the structure can be fine-tuned according to the different traffic flows in different cities, which can greatly improve the storage and retrieval efficiency and ensure the space utilization rate. The entire device is supported only by the central frame, and the rest of the device can be suspended above the green land, which will not affect the lighting of the green land, and can be used in public parking lots, public facilities, or green belts in residential areas.

The pre-tightening adjustment screw 4-10 is sequentially spirally cooperated with the spring pre-tightening slider 4-8 and the front side of the L-shaped vertical plate 4-5. By rotating the pre-tightening adjustment screw 4-10, the compression spring 4-7 can be pre-tightened or relaxed to achieve the purpose of increasing or reducing the pressure between the friction wheel 4-11 and the arc friction belt arm 1-1.

[0068] As a further improvement, the three-dimensional parking garage is also equipped with a card recognition system, a sensor detection device, a mechanical limit device, a parking space vacancy / occupancy display system, etc. The card recognition system is set at the garage entry position, and each floor of the garage is equipped with a proximity sensor for detecting the arrival of the vehicle and a mechanical limit block for limit protection, and lanes 1-9 on the arc parking space 1 are also equipped with a mechanical limit device for wheels to ensure that the vehicle is parked in place. A traffic light is set above each parking space to indicate whether the parking space is vacant or occupied.

[0069] When parking, after the vehicle is identified by swiping the card, it drives into the arc parking space 1 on the first floor, and stops after touching the mechanical limit device on the lane 1-9. The control system identifies the optimal parking position through the algorithm, so that the lifting drive device 7 drives the vehicle-carrying unit 2 to move up and change floors. When it reaches the optimal parking floor, the lifting drive device 7 stops and self-locks. Then, the rotary drive device 6 drives the friction wheel 4-11 to rotate, and drives the arc parking space 1 on the vehicle-carrying unit 2 to rotate circumferentially through the friction transmission between the circular arc friction belt arm 1-1 until the arc parking space 1 reaches the optimal parking position, and moves the idle arc parking space 1 to the vehicle-carrying unit 2, ensuring that the arc parking space 1 can move into place under the detection of the proximity sensor. Thereafter, the lifting drive device 7 moves downward to move the vehicle-carrying unit 2 to the storage position on the first floor, waits for the next parking to arrive, and repeats the above steps.

[0070] The present invention also provides a parking method for a three-dimensional parking garage, comprising the following steps:

[0071] The vehicle enters the arc parking space of vehicle loading unit 2;

[0072] When the vehicle touches the mechanical or electrical limit device on the lane (1-9), the control system uses a self-optimization algorithm to find the nearest free arc parking space and determine the parking path;

[0073] The lifting drive device 7 drives the vehicle-carrying unit 2 to move upward and change floors through the vertical lifting mechanism 5 until it reaches the parking floor where the nearest arc parking space is located;

[0074] The rotary drive device 6 drives the arc parking space to rotate in a rotational manner with the shortest path through the horizontal rotary shifting mechanism 4 until the vacant arc parking space moves to the vehicle carrying unit 2;

[0075] The lifting drive device 7 drives the vehicle-carrying unit 2 back to the initial storage position through the vertical lifting mechanism 5. Parking is completed;

[0076] The present invention also provides a method for taking a car out of a three-dimensional parking garage, comprising the following steps:

[0077] The control system searches for the parking location of the vehicle and determines the route to pick up the vehicle based on the owner's information;

[0078] The lifting drive device 7 drives the vehicle-carrying unit 2 to move upward and change floors through the vertical lifting mechanism 5 until it reaches the parking floor where the vehicle to be picked up is located;

[0079] The rotary drive device 6 drives the arc parking space to rotate in a rotational manner with the shortest path through the horizontal rotary shifting mechanism 4 until the arc parking space carrying the vehicle to be picked up is moved to the vehicle carrying unit 2;

[0080] The lifting drive device 7 drives the vehicle-carrying unit 2 to descend to the initial storage position through the vertical lifting mechanism 5, and the vehicle retrieval is completed.

[0081] like Fig.12 As shown, it is a flow chart of the method of parking in and out of the garage with 3 parking spaces on each floor as an example; when there is no vehicle to be stored or retrieved, the vehicle-carrying unit 2 is parked on the first or second floor. When a vehicle enters the arc parking space on the vehicle-carrying unit, the control system obtains the owner's parking card information through the card swiping system and binds it to the parking space information. The parking priority is determined by the distance of the vacant arc parking space, and the lower floor is given priority, so the first floor is parked first, and the vacant arc parking space closest to the arc parking space of the vehicle-carrying unit 2 on the first floor is rotated to the vehicle-carrying unit 2 and exchanged with the arc parking space of the parked vehicle. The specific method is as follows:

[0082] The car owner can exchange information with the display (HMI). The system receives sensor signals and car owner information to guide the car owner to park safely. After confirmation, the program determines and outputs parking and retrieval information to control the parking garage lifting and rotating motors to complete the storage and retrieval actions until the car carrier unit 2 returns to its position.

[0083] Parking process: When a vehicle needs to be parked, the driver swipes the card to identify the owner's information, and the vertical lifting mechanism 5 drives the vehicle-carrying unit 2 to descend to the bottom initial storage position. The vehicle drives to the arc parking space on the vehicle-carrying unit 2, and after touching the mechanical / electrical limit device on the lane, the control system determines the nearest arc parking space through an algorithm. After the driver confirms that the parking operation is correct (mainly including information such as the vehicle has been turned off, the handbrake has been pulled, the windows have been closed, and there is no one in the car), he leaves the vehicle, and the vertical lifting mechanism 5 starts to operate, lifting the vehicle to the horizontal rotating platform layer with vacant arc parking spaces, and rotates the 4 arc parking spaces on this layer (taking 3 layers, 3 parking spaces on each layer as an example) through friction transmission drive, and rotates the vacant arc parking spaces on this layer to the vehicle-carrying unit 2, and the arc parking spaces with vehicles are stored on this layer. The vertical lifting mechanism 5 drives the vacant arc parking spaces to the initial storage position, waiting for the next vehicle.

[0084] Vehicle retrieval process: When a vehicle needs to be retrieved, the driver swipes the card to identify the owner's information and determine the location of the vehicle. The horizontal rotation shift mechanism 4 drives the arc parking space to rotate according to the shortest rotation distance through friction transmission, and moves the required vehicle to the vehicle loading unit 2; the vertical lifting mechanism 5 drives the vehicle loading unit 2 to automatically descend to the initial storage position, and the vehicle drives out, and the vehicle retrieval is completed.

[0085] The beneficial effects of the present invention are as follows: a cylindrical rotary structure is adopted, and the vehicle storage and retrieval are realized by using two kinds of movements, namely vertical lifting and horizontal rotation and displacement. Only one movable exchange parking space (i.e., the vehicle carrying unit 2) that can be lifted and lowered forms a complete circular track with the incomplete circular arc track of each layer. The horizontal rotation and displacement parking of each layer and each parking space can be realized by driving with a rotary drive device. The structural design is ingenious, the capacity is large, the energy consumption is low, the cost is low, the parking and retrieval action is simple, the floor space is small, and the space utilization rate is high. Moreover, it can be expanded into a medium-sized and large parking garage along the vertical axis and the horizontal radial direction, and the structure can be fine-tuned according to the different traffic flows in different cities, which can greatly improve the storage and retrieval efficiency and ensure the space utilization rate. The entire equipment is supported only by the central frame, and the rest of the equipment can be suspended above the green land, which will not affect the lighting of the green land, and can be used in public parking lots, public facilities, or community green belts and other areas.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
