Description

TECHNICAL FIELD

The present disclosure relates to the field of motor vehicle parking structures of the carousel or vertical tower type comprising mobile vehicle spaces. It furthermore relates to electric handling vehicles, in particular, autonomous conveyors for transporting or moving four-wheeled vehicles.

BACKGROUND

In the state of the art, it is known to use vehicle carousel-type parking towers; these are called “carousel parking,” “stereo garage,” “stereo parking,” “APS” (acronym for “automated parking system”). This type of tower comprises a frame carrying several pods, each pod corresponding to a space in which to park a motor vehicle. The tower further comprises a transport means that carries and translates the pods in a closed path along the frame. These parking spaces increase the number of vehicles parked for a given floor area.

In operation, a person drives the vehicle to be parked, from the entrance of the tower to the empty platform of a pod arranged on the ground level of the tower. The distance traveled is only a few meters. The transport means is then controlled so as to translate the pods along the frame in order to place other vehicles into other empty pods or to return a parked vehicle to its owner. The tower comprises a single entrance allowing a vehicle to enter or exit.

Although satisfactory, it is nevertheless desirable to improve the safety of persons, in particular, operators and customers, allow faster loading and unloading from the customer's point of view, and optimize the number of parked vehicles for a given floor area.

It is also known to have several towers of the carousel type next to each other so that all the entrances of the towers open onto the same street. It is also known to arrange the towers back-to-back.

In parallel, document CN108798118 discloses a carousel-type parking device and an omnidirectional transport carriage adapted to the carousel. The carriage carries a vehicle from a dock to the ground level of the tower in order to place the transported vehicle on an empty pod of the carousel. Each pod comprises four pairs of rods, each pair of rods being provided to receive one wheel of the vehicle. Once the vehicle has been deposited on the rods of a pod, the carriage can pass through the pod.

This device has the disadvantages of the need for loading and/or unloading platforms, which increases the area necessary for the correct operation of the parking structure, and relatively long installation time due to the presence of rods as vehicle support means. In addition, in the event that the carriage fails, it is not possible to place or recover a vehicle manually via a physical person.

The present disclosure therefore aims to improve the care of vehicles in order to offer a faster and more secure service for people to optimize the space available.

DETAILED DESCRIPTION

FIG. 2 shows an automatic parking system for parking motor vehicles comprising a carousel-type parking tower 11. The tower allows for the storage and retrieval of motor vehicles 100.

According to the embodiment shown, the tower comprises a vertical frame 50 having twelve pod spaces. The frame further comprises on the ground level a tower entrance 51 and a tower exit 52 for the passage of a transport conveyor carrying, or not carrying, a vehicle. The frame is arranged and configured to have opening dimensions of the tower entrance and the tower exit allowing a transport conveyor to pass through the tower. Depending on the direction of travel, a tower entrance 51 may be a tower exit 52 and vice versa.

The tower comprises twelve pods 60 connected to the frame 50. Each pod comprises a structure connected to a pod space. In this embodiment, the tower has as many pods as there are pod spaces. Each pod 60 comprises a storage tray 65 corresponding to a parking space of a motor vehicle 100. Each pod has a pod entrance 61 and a pod exit 62 for the vehicle to pass through. The pod is loaded or unloaded when it is placed on the ground level of the tower, as shown in FIG. 2. The structure of each pod is arranged and configured to have opening dimensions of the pod entrance and the pod exit allowing a transport conveyor to pass through the pod. Depending on the direction of travel, a pod entrance 61 may be a pod exit 62 and vice versa.

For the foregoing and for the rest of the description, a loaded pod is understood to mean a pod occupied by or storing a vehicle. In addition, an unloaded pod is understood to mean a pod that is empty or unoccupied by a vehicle.

FIG. 2 shows a carousel-type parking tower having several floors and comprising 12 pods and arranged in two columns. According to other embodiments, the parking towers may, for example, comprise between 6 and 20 pods arranged in two columns.

In order to move the pods, the parking tower comprises a means for actuating in translation (not visible in the figures) pods according to a closed path along the frame, the path being illustrated in FIG. 3, which shows several carousel-type parking towers. The actuation means, for example, comprises at least one actuator and connection means enabling the pods to be pulled along the vertical frame of the tower.

The parking system comprises at least one transport conveyor 90. Each transport conveyor is arranged to roll on the floor and, in particular, on the ground level of the carousel-type parking tower. Each transport conveyor is further arranged to pass through a pod by going through a pod entrance 61 and a pod exit 62 by rolling on the storage tray 65, see FIG. 1.

Each transport conveyor 90 is arranged to lift the four wheels of a motor vehicle so as to carry the vehicle. According to one embodiment shown in FIG. 7, the at least one conveyor comprises wedging arms 21, 22, 23, 24, 31, 32, arranged to be positioned on either side of the treads of the wheels of the vehicle so as to carry or deposit the vehicle.

The transport conveyor 90 comprises a chassis comprising a main beam 2 and a secondary beam 3 that is mounted slidably inside the main beam 2. A cylinder or a linear actuator (not shown), for example, a worm gear actuator, allows the secondary beam 3 to be actuated relative to the main beam 2 in order to obtain a telescopic chassis.

The main beam 2 of the chassis comprises a front transverse side member 25, which is fixed and which bears two fixed arms 21, 22 and two deployable front arms 23, 24, which are pivotably movable relative to the front side member. The deployable front arms 23, 24 are actuated by electric motors or cylinders, in order to move between:

• • a neutral position, in which the deployable front arms extend parallel to the main beam in order to allow the transporter to drive under the vehicle to be loaded without touching the wheels of the vehicle; and
  • a deployed locking position, in order to allow contact with the treads of the wheels of the vehicle.

In the deployed position, the spacing between each pair consisting of a fixed arm and a facing deployable arm 21, 23 and 22, 24 is determined so that they come into contact with the front and rear walls of the tire of the vehicle and grip the tire in order to allow the vehicle to be lifted. To facilitate lifting, the fixed arms 21, 22 have an inclined ramp 28, 29.

When the deployable front arms 24, 23 are in the deployed locking position, they stop the vehicle from moving relative to the transport conveyor 90.

The secondary beam 3 of the chassis likewise comprises a rear transverse side member 35, which bears two deployable rear arms 31, 32 that are pivotally movable relative to the rear side member. The deployable rear arms 31, 32 are actuated by electric motors or cylinders, in order to move between:

• • a neutral position, in which the deployable rear arms extend parallel to the secondary beam in order to allow the transporter to drive under the vehicle to be loaded without touching the wheels of the vehicle; and
  • a deployed locking position, in order to allow contact with the treads of the wheels of the vehicle.

The length L of the side members 25, 35, measured between the pivot shafts of the deployable front arms 23, 24 and of the deployable rear arms 31, 32 is less than Vmin-Lmin, where:

• • Vmin denotes the typical and minimum track of a car, typically 1600 millimeters,
  • Lmin denotes the typical width of the tire of a car, typically 220 millimeters.

The length L of the side members is therefore typically less than 1400 millimeters, and preferably about 1200 millimeters.

The length of the fixed arms 21, 22, of the deployable front arms 23, 24 and of the deployable rear arms 31, 32 is determined so as to correspond to half of the width lmax, which corresponds to the width between the outer walls of the wheels of a large car, minus the length of the side member 25, 35, which is typically 500 millimeters for each of the arms.

The conveyor may thus be positioned along the axis of the vehicle, when the conveyor is running on a storage tray 65, in order to allow the chassis of the conveyor to pass under the vehicle with the wedging arms 23, 24, 31, 32 in the folded position, oriented substantially longitudinally, until the ramps 28, 29 of the fixed arms 21, 22 abut the front wheels of the vehicle.

The deployable wedging arms 31, 32 are then moved into the transverse position. The secondary beam of the chassis is actuated forward in order to adjust to the wheelbase of the car to be loaded and to bring the deployable wedging arms 31, 32 into contact with the rear treads of the wheels of the vehicle.

The wedging arms 23, 24 are deployed to move the vehicle onto the fixed arms 21, 22.

According to a variant embodiment and in a complementary manner shown in FIG. 8, the secondary beam 3 of the chassis further comprises two deployable distal arms 33, 34 that are pivotally movable relative to the rear side member. The deployable distal arms are actuated by electric motors or cylinders, in order to move between:

• • a neutral position, in which the deployable distal arms extend parallel to the secondary beam 3 in order to allow the transporter to drive under the vehicle to be loaded without touching the wheels of the vehicle; and
  • a deployed locking position, in order to allow contact with the treads of the wheels of the vehicle.

In the deployed position, the spacing between each pair of arms consisting of a rear arm 31, 32 and a facing distal arm 31, 33 and 32, 34 is determined so that they come into contact with the front and rear walls of the tire of the vehicle and grip the tire in order to allow the vehicle to be lifted. When the deployable distal arms 34, 33 are in the deployed locking position, they stop the vehicle from moving relative to the conveyor.

In a manner not shown, the at least one transport conveyor comprises a guide means allowing it to be moved autonomously. Furthermore, the parking system comprises control means arranged to control the actuation means and the means for autonomous guidance of the at least one conveyor.

The presence of a transport conveyor added to the presence of a vehicle on the storage tray of a pod causes an overweight for the structure of the pod.

With reference to FIGS. 4 and 5, the parking system further comprises support means 70 arranged on the ground level of the at least one tower. The means are arranged to at least partially support the weight of a transport conveyor 90 carrying a vehicle 100. A transport conveyor can then pass on each pod, making it possible to propose an automatic parking system offering faster service that is safer for people.

With reference to FIG. 4, a pod 60 is positioned on the ground level of a carousel-type parking tower, the tower comprising as many pods as pod spaces. The tower comprises N pods and N pod spaces. The support means 70 comprise load-absorbing rollers 72 protruding from the ground level of the at least one tower. The rollers make it possible to support the pod 60 during a loading or unloading of a vehicle by a transport conveyor (not shown) arranged on the storage tray.

With reference to FIG. 5, a carousel-type parking tower comprises N−1 pods 60 and an empty pod space 59. The support means 70 comprise a platform 71 protruding from the ground level of the at least one tower.

Preferably, the automatic parking system comprises at least two parking towers of the carousel type arranged one behind the other: at least one passage tower and one destination tower so that a tower exit of one tower is opposite a tower entrance of the next tower so that the at least one conveyor 90 carrying or not carrying a vehicle can pass directly from one tower to another. This set of towers defines a number R, R being equal to at least 2, of rows of towers, the destination tower being positioned at least in row 2. The at least two carousel-type parking towers are aligned so as to form a line.

According to one embodiment shown in FIG. 1, the automatic parking system comprises six carousel-type parking towers 11, 12, 13, 14, 15, 16 aligned in the longitudinal direction of the towers and defining six rows of towers R1, R2, R3, R4, R5, R6. According to this embodiment, each parking tower comprises as many pods as pod spaces. To access a pod, referred to as a target pod 60c, of a destination tower, the transport conveyor rolls on the storage trays of the empty pods of the passage towers, the empty pods being arranged on the ground level of the passage towers.

With reference to FIG. 1, the target pod 60c is located in the parking tower 14, in this case called a destination tower, the tower being located in row 4 of the parking system. The transport conveyor 90 enters through the entrance of the parking tower 11 and then rolls onto the empty pods of the parking towers 11, 12 and 13 before accessing the parking tower 14. In this case, the parking towers 11, 12 and 13 are passage towers. Then, not shown, the transport conveyor rolls on the storage tray of the target pod 60c by fitting under the vehicle. The vehicle is lifted and carried by the conveyor 90. The transport conveyor 90, carrying the vehicle, exits the target pod by rolling on the storage trays of the empty pods.

According to an alternative embodiment shown in FIG. 3, the automatic parking lot system 1 comprises a number L, L being equal to three, lines L1, L2, L3 of carousel-type parking towers, arranged next to each other, each line of parking towers comprising four rows R1, R2, R3, R4 of parking towers.

The parking control method associated with the automatic parking system, with reference to FIGS. 1 and 6, will now be described.

The method provides for:

• • a step of choosing a target pod 60c, referred to as target pod, of a destination tower, for storing or retrieving a motor vehicle 100,
  • a step of controlling the actuation means of the four parking towers 11, 12, 13 and 14, comprising:
  • moving the pods 60 of the destination parking tower 14 to place the target pod 60c on the ground level, and
  • moving the pods of one or more of the three passage parking towers 11, 12 and 13 so as to align an empty pod of each passage tower with the target pod 60c of the destination parking tower 14,
  • a step of controlling the movement of the empty transport conveyor 90, to pass through all the passage parking towers 11, 12 and 13, and access the target pod 60c of the destination parking tower 14 to retrieve the vehicle from the target pod 60c.

Preferably, the control means of the parking system, also called a parking management system, comprises a system for managing the robotic conveyors 90 and a system for managing the carousel-type parking towers.

The method provides for detecting the position of the at least one conveyor, and the position of the pods of the various towers, in particular, the position of the target pod.

Preferably, the method provides for simultaneously controlling the pods of several parking towers and one or more conveyors. The robot management system controls the autonomous guidance means of the conveyors. The system for managing carousel-type parking towers controls the means for actuating the tower.

Furthermore, wireless communication means between the control means and the means for guiding the conveyors allow transmission of the addresses of the target pods 60c to the conveyors 90.

The method makes it possible to coordinate and/or synchronize the movements of the transport robotic conveyors and the movements of the pods of the various carousel-type parking towers and thus propose a parking of the motor vehicles allowing, with regard to the prior art, storage and retrieval that is faster and safer for people while optimizing the space available.
