DESCRIPTION

Device for the controlled movement of vehicles on electric charging platforms for robotic parking systems

TECHNICAL SECTOR

The present invention relates to a device for moving vehicles on electric charging platforms for robotic parking systems with a lateral movement system using conveyor belts.

The object of the invention is to provide means that allow offering a precise and controlled movement of the vehicle along the parking facilities in order to be able to use a standard charging system for the different existing electric vehicles as simple as possible.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, robotic car parks are known, such as the one described in the invention patent P201000366, in which a vehicle storage silo with one or several levels is defined in which three well-differentiated zones are established, a vehicle transfer area, a vehicle maneuvering area with one or more industrial lifts and a robot that distributes vehicles to the different spaces.

Although this type of installation does not present hardly any limitations when it comes to vehicles with an internal combustion engine, when it comes to electric vehicles, the lack of standardization of connectors and their position on the vehicle body makes it impossible for the recharging of the batteries of electric vehicles can be carried out in an automated manner within the places provided for in the installation.

In this sense, the user does not have access to the parking silos of these facilities, which is a problem for this type of vehicle.

The reality is that in recent years the sales of electric cars are skyrocketing.

Many users choose this option, especially to move around cities, so that the currently existing automated parking systems have the limitation of not being able to offer the electric recharging service.

Trying to avoid this problem, the applicant himself is the owner of utility model U201932094, which describes an automatic electric charging equipment for vehicles in robotic parking lots, in which three elements that are related to each other participate; a terminal that adapts to the user's electric vehicle, a mechanism that is integrated into the places designed to receive electric vehicles and a conventional charging module associated with the previous mechanism.

Based on these elements, at the entrance or transfer area of the car park, the vehicle in question will be detected, previously registered in the car park database, and consequently the vehicle model and type of connector required will be identified, facilitating the specific terminal, materialized in a casing with magnets, so that the user can position it on the hood of their vehicle at a specific point that will be indicated by a direct projection on said hood, casing in which an extensible cable with the appropriate connector is integrated to the vehicle in question, which the user must connect in said vehicle reception area, so that the cable will be connected to a standard connector established on the front face of said terminal casing.

From this point on, the process of collecting and loading the vehicle will be fully automated, so that through the robotic means of movement and distribution of the vehicles provided for in the installation, the vehicle will be transported in a fully automated manner to the place that has been assigned, a place in which a mechanism materialized in a three-axis Cartesian positioning system is established for a standard connector, complementary to the connector provided on the front face of the terminal implanted on the hood of the vehicle, and associated with a station conventional load.

In a first stage, the two main axes will act, perpendicular to the plane of the car to detect the charging terminal through the corresponding sensors, by means of successive sweeps to detect the terminal. Subsequently, the third axis will act to connect the terminal of the vehicle to the general charger. When the plug-in arm detects the connection, the system starts charging.

The problem with this solution is that this Cartesian positioning mechanism is extremely complex and consequently expensive, so that it would be desirable to be able to dispense with it, although for this it is necessary to ensure that there is no relative movement between the vehicle and the different platforms. and mechanisms through which the vehicle moves within the installation, that is to say along the vehicle transfer zone, the vehicle maneuvering zone and the vehicle distributor robot to the different loading places, where the movements of the vehicle are carried out by means of lateral translation systems by means of conveyor belts in which the wheels of the vehicle are susceptible to small slippages depending on the degree of tire wear.

EXPLANATION OF THE INVENTION

The device for moving vehicles on electric recharging platforms for robotic parking systems that the invention proposes fully satisfactorily resolves the aforementioned problems, allowing to guarantee a correct confrontation of the standard connector implanted on the vehicle with the charging point of the battery. final place in which the vehicle is stored without having to use complex and extremely expensive intermediate three-axis positioning mechanisms.

For this, the device of the invention is intended to be implanted on the lateral translation system by means of conveyor belts of the platform on which the vehicle is deposited and to move with it throughout the entire installation, in such a way that it is linked to a of the wheels of said vehicle, preventing its lateral slipping, giving greater rigidity and consistency in the movement of the vehicle that ensures perfect control of its relative position throughout the entire installation, being able to guarantee that, when the vehicle is placed on the final square in which the recharging module is located, the standard connector installed on the positioning platform that the invention describes is perfectly facing the complementary connector of the recharging module.

More specifically, the device is constituted from a kind of tray or laminar body of steel that has plan dimensions greater than the plan dimensions of the wheel of the electric vehicle to receive, with a width according to the width of the conveyor belts present in the different movement mechanisms of the vehicle throughout the installation, on which it is movable, which has the particularity of including a projection in correspondence with one of its lateral ends, on which the tire of the vehicle will abut vehicle, and which has a configuration similar to that of the sides of the entrance rails to the elevator and where the loading point will be located.

The other end has a slight crease to prevent accidental snagging when running over plastic or rubber bands.

On the lower face it has a thermo-adhered rubber to prevent relative movements between the piece and the bands and on the upper side, optionally, a UHMW-PE (Durogliss®) polyethylene band to be able to relocate the vehicle without friction, reducing the tangential stresses on the joints. between the different pieces.

The device can be a single piece or it can be a set of 2 pieces applied to the two wheels of one of the two axles of the vehicle or 4 pieces forming a tray, depending on how you want to move the vehicle within the car park. function of the number of wheels of the same on which it is applied.

Furthermore, and unlike the utility model U201932094, the connection means between the standard connector that is implanted on the positioning platform that the invention describes and the conventional recharging module do not necessarily have to be physical connectors, so that they can materialize in charging media by magnetic induction, which increases the margin of error in the relative positioning between both elements.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the device of the invention is intended to be used in robotic car parks with means for electric recharging of vehicles in which a vehicle reception area is established, as well as a series of robotic means for the storage of said vehicles in different places, where each electric vehicle (1) is assigned a positioning platform with a connection system to the integrated charger, so that a terminal (2) is established that includes a cable (3) with a specific connector for the specific model of the vehicle that allows it to be connected to it, regardless of where its charging point is located.

As can be seen in figures 2 and 3, the vehicle moves through the different elements of distribution and positioning of the vehicle in the robotic parking facilities through pairs of bands conveyors (6) on which the vehicle wheels rest.

Well, according to the invention, and as can be seen in figure 3, the device that is recommended is materialized in a kind of tray or laminar body (8) of steel that has plan dimensions greater than the plan dimensions of the wheel (7) of the electric vehicle to receive, with a width according to the width of the conveyor belts (6) on which it is intended to rest stably and move together with them, from one conveyor belt to another , laminar body (8) that includes a projection (9) in correspondence with one of its lateral ends, on which the vehicle tire abuts, and that has a configuration similar to that of the sides of the rails that give access to the conveyor belts (6), specifically the entrance rails to the platform (10) of the elevator.

The device ends at its opposite end in a fold (11) in the upper direction, to avoid accidental snags when moving from one conveyor belt (6) to another.

On the lower face it has a thermo-adhered rubber (12) to avoid relative movements between the piece and the conveyor belts (6) while on the upper face it is capable of incorporating a UHMW-PE (Durogliss®) polyethylene band to be able to relocate the vehicle without friction, reducing the tangential stresses on the joints between the different parts.

Based on this structuring, the different mechanisms that participate in the robotic parking allow the vehicle (1) to be precisely matched with the connector (4) of the corresponding charging module (13) during the movement of the vehicle within the installation, without the need to use complex positioning systems for said charging module connector.

Finally, it only remains to point out that, as has been said previously, the device of the invention may be applied to one, two or all four wheels (7) of the vehicle depending on the level of precision required, depending on the means of connection physical or inductive provided between the charging module (13) and the terminal (2).
