Description

Electric vehicle charging device

Field of the invention

The present invention relates to the field of charging devices for electric vehicles, making it possible to electrically supply electric vehicles, when the latter are parked, in order to charge their accumulators or operate their electrical equipment.

Prior art

Vehicles, and in particular rolling vehicles, are more and more often equipped with an electric motor. These vehicles can be vehicles whose motorization is exclusively electric, or rechargeable hybrid vehicles for which another type of energy is associated with the electric motorization. To power these engines electrically, these vehicles are most often equipped with accumulators, which can for example be batteries and/or capacitors. These accumulators must be electrically charged when the vehicles are parked. For this, it is generally planned to park the vehicles on sites specially equipped to allow their charging, where they can be connected by a cable to a power supply network.

Other vehicles are also known which, although not equipped with an electric motor, require, when they are parked, to be connected to an electric power source in order to operate equipment or to charge accumulators. This is the case, for example, of refrigerated vehicles, whose cooling modules must often be electrically powered by an external power supply when the vehicle's internal combustion engine is off.

All such vehicles which must, when parked, be connected to an external power source, are hereinafter referred to as "electric vehicles".

The very strong increase, in proportion, of electric vehicles makes it necessary to equip a growing number of parking spaces to allow them to be charged. This need is further accentuated by the appearance of unmanned autonomous vehicles, which can in particular be used for the transport of people or goods. It is therefore necessary to provide solutions for equipping large numbers of parking spaces, so that the electric vehicles parked there can be electrically charged.

To equip such parking spaces, the most common solution is to place a charging station, connected to the electricity grid, next to the parking space. The user can deploy a cable between this terminal and a socket, provided on the vehicle, into which this cable can be plugged.

The connection of such cables, however, imposes on the user restrictive manipulations, each time he parks his vehicle. Moreover, such manipulations are not possible for an autonomous vehicle having no human driver.

We know, for example from document US 6,157,162, robotic arm solutions, carried by an electric charging station, capable of identifying a vehicle parked opposite this terminal, of locating its connection socket, of opening the cover covering it , if applicable, and connect the end of a cable to it in order to power the vehicle.

Such solutions make it possible to considerably simplify the recharging of the vehicle. However, they require each charging station to be associated with an extremely expensive robotic arm that requires significant maintenance. Such a solution can therefore only be deployed with difficulty on a large number of parking spaces. Moreover, in some cases, the implementation of such a solution requires considerable modification of the configuration of the parking space. Consequently, this installation is sometimes impossible on certain locations, or even in certain car parks, in particular when these car parks are too cramped.

Some motor vehicles are also equipped with inductive charging interfaces, comprising windings, placed on the underside of the vehicle. Such an inductive charging interface is intended to be placed opposite an inductive charging terminal. This terminal comprises a winding which, traversed by an alternating electric current, generates a magnetic field. This magnetic field, passing through the windings of the inductive charging interface of the vehicle, generates therein an induced electric current, which can be used for the electrical charging of the accumulators of the vehicle.

To perform such a charge, it is necessary for the inductive charging terminal to be perfectly placed facing the inductive charging interface of the vehicle. When a parking space is equipped with such an induction charging station, it is therefore most often also equipped with shoes and rails, aimed at guiding the wheels of the vehicle to ensure its precise positioning on the parking space. Parking the vehicle in such a location is therefore tricky and restrictive for the driver. In particular, it may require the user to park his vehicle in a predetermined parking direction. Moreover, the position of the inductive charging interfaces on the underside of the vehicles, relative to the wheels of the vehicle, is not currently standardized on the different models of vehicles. A parking space having such equipment suitable for a vehicle can therefore hardly be used for charging an electric vehicle of another model.

Finally, the efficiency of inductive charging decreases when the charging station is remote from the inductive charging interface of the vehicle. To reduce this distance, the charging terminals by induction can be placed protruding from the floor of the parking spaces. However, the heights of the vehicles being variable, such terminals can hardly be both effective for supplying a vehicle whose body height is high, and not risk coming into contact with a vehicle whose height checkout is low.

To avoid this difficulty, there are charging terminals whose height is variable, to come into contact with the inductive charging interface of the vehicle placed above. US 5,821,731 shows such terminals. Such solutions are expensive to implement, for each parking space, and require significant maintenance.

To allow easier positioning of the charging terminal by induction, relative to the charging interface by induction of the vehicle, it was imagined to make this mobile terminal. The terminal then behaves like a robot that can move, for example using wheels, on the ground of the parking space to position itself, under the vehicle, opposite the inductive charging interface of the vehicle . This robotic terminal can also have a variable height, in order to minimize the distance between the terminal and the inductive charging interface.

Such a solution, which is for example known from document US Pat. No. 5,821,731, allows efficient charging of electric vehicles while minimizing the constraints for the user. On the other hand, it requires equipping each parking space with a mobile robotic terminal. The high cost and the need for maintenance of such terminals make it difficult to deploy such solutions on a large number of parking spaces.

Objectives of the invention

The present invention aims to overcome these drawbacks of the prior art.

In particular, the aim of the invention is to propose an efficient solution for charging electric vehicles, which can be deployed on numerous locations in a car park for a reasonable installation and operating cost.

Another object of the invention is to provide such a device which limits as far as possible the operations to be carried out by the user wishing to load his vehicle.

A particular objective of the invention is to provide such a device allowing the charging of an autonomous electric vehicle, without the intervention of a human user.

These objectives, as well as others that will appear more clearly later, are achieved using an electric vehicle charging device for a parking lot that includes:
- at least one power supply station;
- at least one mobile connection equipment, comprising an inductive coil, this mobile connection equipment being capable of being electrically powered by an electrical power cable connected to this electrical power supply station and capable of cooperating with a charging interface by induction of a vehicle to transmit to it a magnetic field produced by the inductive coil;
- a manipulation robot, capable of moving independently in the car park;
- this manipulation robot comprising manipulation means capable of transporting the mobile connection equipment, and of placing it facing an inductive charging interface of a vehicle, the charging device comprising, according to the invention, of the holding means capable of holding this mobile connection equipment facing the inductive charging interface of the vehicle, the manipulation means being configured to autonomously grasp the mobile connection equipment in order to transport it, and to release this mobile connection equipment when it is held by the holding means opposite the inductive charging interface.

Such an electric vehicle charging device makes it possible to equip a large number of parking spaces while limiting the costs of the overall installation, since the same handling robot can be used to successively handle several mobile connection equipment, in several parking spaces. A single one of these robots, often expensive, therefore allows the equipment of several parking spaces.

This electric vehicle charging device is also suitable for supplying non-standardized vehicles or vehicles that may have variable underbody heights.

In addition, the use of the car park is facilitated for users. Thus, they do not have to perform any manipulation to allow their vehicle to be powered. In addition, the direction and the exact parking position of their vehicle are irrelevant due to the ability of the handling robot to move in the parking lot. The use of such a handling robot also allows the charging of autonomous electric vehicles.

Advantageously, the handling means comprise at least one gripper capable of gripping the mobile connection equipment.

Thus, the mobile connection equipment can be manipulated, lifted, moved or even positioned opposite the inductive charging interfaces of an electric vehicle or the support of the electrical power station, for example.

According to a preferred embodiment, the mobile connection equipment is connected to the power supply cable in a removable manner, the charging device being configured to allow the connection of this mobile connection equipment to the power supply cable or the disconnection of the mobile connection equipment of the power supply cable, when the mobile connection equipment is transported by the handling robot.

This embodiment makes it possible to easily move the mobile connection equipment. It also allows the same mobile connection equipment to be used successively on several separate parking spaces. The number of mobile connection devices used in the car park can thus be less than the number of slots allowing electrical charging, which makes it possible to further reduce the cost of equipping the car park.

In this case, advantageously, the electric vehicle charging device comprises reversible locking means of the power cable on the mobile connection equipment.

Such reversible locking means, that is to say capable of moving alternately from a locked position to an unlocked position, make it possible to prevent disconnection of the mobile connection equipment from the power supply cable, when this disconnection is not desired, and to facilitate this disconnection when it is desired. These locking means can advantageously be driven by motorized means which can be controlled remotely.

Advantageously, the power supply cable is at least partially retractable in a box of the power supply station.

Thus, the cable can take a retracted position, in which the cable is at least partially retracted in the box and therefore limits the risk of accident, and a deployed position, allowing the power supply socket to reach a large part from the surface the parking space.

Preferably, the power supply station and the manipulation robot have complementary shapes ensuring precise positioning of the manipulation robot with respect to the power supply station, when the manipulation robot approaches the power station. electric.

This complementarity of shapes can in particular facilitate the connection of mobile connection equipment carried by the handling robot with a retracted cable in the power supply station.

Preferably, the means for holding the mobile connection equipment opposite the inductive charging interface of the vehicle comprise at least one electromagnet included in this mobile connection equipment, making it possible to generate a force holding this mobile connection equipment against a ferromagnetic mass of the vehicle.

These holding means thus allow the mobile connection equipment to be easily fixed opposite the inductive charging interface of the vehicle, without it being necessary to implement complex and potentially fragile mechanical means. Such holding means are moreover very easily controllable, the interruption of the power supply to the electromagnets resulting in the instantaneous interruption of the holding. This easy maintenance of the mobile connection equipment facing the inductive charging interface of the vehicle allows the handling robot that brought the mobile connection equipment to leave it in position, and to leave for another location.

In such a case, according to a particular embodiment, this electromagnet is constituted by the inductive coil.

It is thus possible to simplify the mobile connection equipment, which may contain only a single coil ensuring at the same time the function of generating an alternating magnetic flux allowing the transmission of energy by induction and the function of maintaining the mobile connection equipment next to the vehicle's inductive charging interface.

According to a particular embodiment, the electric vehicle charging device also comprises at least one mobile connection device, capable of being electrically powered by an electrical power cable connected to the electrical power supply station, and comprising at least one connection socket capable of being connected to a connection socket of a vehicle, this mobile connection device having a shape making it suitable for being gripped by the handling means.

The charging device according to the invention thus makes it possible to ensure the charging of vehicles not equipped with the inductive charging interface, by offering the user to connect the mobile connection equipment to his vehicle. This mobile connection equipment can advantageously be manipulated by the robot in the same way as a mobile connection equipment.

Detailed Description of Embodiments of the Invention

The schematically represents a parking lot equipped with an electric vehicle charging device according to one embodiment of the invention.

This parking lot has

several parking spaces

101, 102 and 103. The electric vehicle charging device is configured such that each of these parking spaces 101 to 103 allows the charging of an electric vehicle which is parked. For this, each of the parking spaces 101 to 103 is associated with a power supply station, placed at the edge of the parking space. Thus, on the , the parking spaces respectively 101, 102 and 103 are each associated with a power supply station, respectively 201, 202 and 203, which is fixed to the wall 109, on the edge of each of the parking spaces 101 to 103.

The parking lot represented by the is also equipped with several mobile connection equipment, intended to be connected to one of the power supply stations 201 to 203 by means of a power supply cable and to be brought into contact with a charging interface by induction of a vehicle to allow its charging. On the , two

mobile connection equipment

301 and 302 are represented. The mobile connection equipment 301, placed on the parking space 101, is connected by a power supply cable 29 to the power supply station 201. The mobile connection equipment 302, on the other hand, is not connected to any power supply station in the configuration shown in the .

The charging device represented by the finally comprises a robot 4 for handling the mobile connection equipment. This manipulation robot 4 is capable of carrying mobile connection equipment and of moving it to another place in the parking lot. Preferably, this manipulation robot 4 operates with at least one electric motor and has accumulators in order to store the energy enabling it to operate autonomously. On the , this manipulation robot 4 carries the mobile connection equipment 302, which it can thus move.

The represents, in perspective, a mobile connection equipment 3 similar to the

mobile connection equipment

301 and 302 represented on the .

This mobile connection equipment 3 has a substantially flat housing 31, which notably comprises a face 32, substantially flat in the embodiment represented, which is the upper face in the configuration represented by the . The housing 31 also has another face 36, substantially planar in the embodiment shown, opposite the face 32 and which forms in the configuration represented by the the underside of the case. Face 32 is intended to be placed against an inductive charging interface of an electric vehicle. Furthermore, this mobile connection equipment 3 has, on one of the side faces of the case 31, a socket 33 into which the complementary socket of an electric power cable can be plugged.

The schematically represents a sectional view of the mobile connection equipment 3 along a plane parallel to its face 32, when a socket 291 of an electrical power cable 29 is connected to the socket 33 of the equipment Connect mobile 3.

The socket 291 and the socket 33 are advantageously equipped with locking means, making it possible to prevent their separation, when they are connected. The represents an example of such locking means that can be implemented. In this example, these locking means consist of mobile hooks 311, carried by the housing 31, which can cooperate with lugs 2910 provided on the socket 291 to hold it in position, when it is plugged into the socket 33. Advantageously, these locking means can be controlled. Thus, for example, actuators 312 provided in housing 31 can move mobile hooks 311 to remove them from lugs 2910 of socket 291, when it is desired to disconnect socket 291 from socket 33. Of course, this solution represented schematically by the is only one example, and those skilled in the art can easily implement other equivalent locking means.

In the case 31 of the mobile connection equipment 3, the socket 33, which is electrically powered by the power supply cable 29, is connected by wires to a power supply management module 34. This power supply module power management 34 may include, for example, an electrical transformer, controlled switches, fuses, and the like. This power supply management module 34 electrically supplies an inductive coil 35 extending in the housing 31, substantially parallel to the face 32. When it is traversed by an electric current, this coil 35 generates by induction a magnetic field oriented in a direction normal to face 32.

Thus, when the face 32 of the mobile connection equipment 3 is placed against an inductive charging interface of a vehicle, or close to this interface, and the coil 35 is traversed by an alternating electric current, this coil 35 generates an alternating magnetic field which, passing through a coil of the inductive charging interface of the vehicle, generates an induced alternating current therein, which can be advantageously used to charge the accumulators of the vehicle. The principle of such an induction charge, which is well known to those skilled in the art, will not be described in more detail in this document.

According to a particularly advantageous embodiment of the invention, the mobile connection equipment 3 has a face 36 opposite its face 32, which is parallel to the face 32 and has an identical shape. Furthermore, the

faces

32 and 36 are positioned at the same distance from the coil 35. Thus, each of the

faces

32 and 36 can be, indifferently, placed against the inductive charging interface of a vehicle to supply it electrically. . The positioning and handling of this mobile connection equipment 3 can therefore be done without taking into account its direction of orientation, as long as one of its

faces

32 or 36 is placed facing the inductive charging interface of the vehicle. The handling of this mobile connection equipment 3 is therefore facilitated.

Furthermore, advantageously, the housing 31, of flat shape, has a relatively small thickness, preferably less than 5 cm, between its

faces

32 and 36. Thus, this housing, when it is placed on the ground, does not represent than a thin obstacle. If a vehicle were to accidentally roll over such a housing 31, this would not greatly disturb the driving of the vehicle. The housing 31 is also designed and sized to be able to withstand being crushed by a vehicle wheel without being damaged.

Finally, advantageously, the

faces

32 and 36 of the mobile connection equipment 3 are designed so as to allow this equipment to slide easily on the ground. For this, the

faces

32 and 36 are advantageously devoid of asperities likely to catch the ground, and are preferably made of materials with a low coefficient of friction. They can also, in a variant, be equipped with pads having a low coefficient of friction.

Thus, according to a particular aspect of the invention, the latter relates to mobile connection equipment for an electric vehicle charging device, this mobile connection device being capable of being electrically powered by a power cable, this mobile equipment connection comprising a coil capable, when it is electrically powered, of generating a magnetic field capable of carrying out a charge by induction, this mobile connection equipment having a first external face, substantially perpendicular to the direction of the magnetic field generated by the coil, this first external face having a shape making it suitable for being placed facing an inductive charging interface of a vehicle, this mobile connection equipment being characterized in that it has a second external face, substantially perpendicular to the direction of the magnetic field generated by the coil, on the side opposite to the first external face, this second external face e having a shape making it suitable for being placed facing an inductive charging interface of a vehicle.

According to an advantageous embodiment of this aspect of the invention, the first face and the second face are placed at the same distance from the coil.

According to an advantageous embodiment, the first face and the second face have identical shapes.

In such a case, the mobile connection equipment is reversible and can be used indifferently in one direction or the other.

According to an advantageous variant, the first face and the second face have different shapes, each of the two faces being capable of being brought into contact with a particular type of vehicle induction charging interface.

Advantageously, the first face and the second face are separated from each other by a distance of less than 5 cm.

The represents a power supply station 2 which is fixed to the wall 109, on the edge of a parking space 1. The power supply station 2 is contained, at least in part, in an oblong box 21, i.e. that is to say an elongated shape, the length of which is oriented in a direction called the longitudinal direction of the box 21, corresponding to its length. In the embodiment shown, this longitudinal direction of box 21 is advantageously horizontal, and box 21 extends along wall 109 over the entire width of parking space 1. When

several parking spaces

101, 102 and 103 are neighbors, as represented by the , the boxes of each of the

power supply stations

201, 202 and 203 can thus be placed in contact with each other, so as to form a plinth allowing the circulation of the cables of a power supply network along the wall 109. When the boxes of the various power supply stations are not in contact with each other, they can advantageously be connected by plinths allowing the circulation of the cables of a power supply network.

In the embodiment shown in Figures 1 and 4, the power supply stations 2 are fixed to a wall 109. It is however possible that such power supply stations 2 are placed on the periphery of a parking space 1 without being fixed to a wall, for example when no wall delimits this location. In such a case, the box 21 can be carried by a suitable support fixed to the ground, on the outskirts of the parking space.

Preferably, the box 21 is fixed to the wall 109, or on a suitable support, at a distance from the ground of several centimeters, preferably of the order of 10 cm. Such a distance makes it possible to prevent water from coming into contact with the components of the power supply station 2, in the event of accidental flooding occurring in the car park.

The schematically represents the components placed in the casing 21 of the power supply station 2. This casing 21 comprises at least one cable of a power supply network 22, capable of powering the power supply station 2 electrically. of a power supply network 22 advantageously runs over the entire length of the box 21, so as to allow the power supply of the power supply station 2, as well as the power supply stations which are close to it.

This power supply network 22 feeds a power supply server 23, which controls the power supply to be supplied to the vehicle to be charged. According to a possible solution, this electric power supply server 23 can directly deliver the electric power coming from the network to the vehicle.

According to another preferred embodiment, this electric power supply server 23 comprises components making it possible to control the electric power supply to be supplied to the motor vehicle. Thus, it can contain transformers, fuses and control devices, making it possible to deliver to a vehicle an electric current configured according to various parameters. The duration during which electric current is supplied, the power supplied, the energy supplied, can be controlled by software, for example according to the payment made by the user of the vehicle. Furthermore, the electrical power supply server 23 can also comprise components performing anomaly detection, detection of the connection of a vehicle to be charged, or even the processing of information originating from the vehicle or a communication with this vehicle.

It is also possible, in a variant, for a power supply server common to several power supply stations to control the power supply delivered by each of these power supply stations. In such a case, this common power supply server can for example be located in an electrical cabinet located near the parking spaces. It can then communicate, so as to exchange information or instructions with different components of the device, for example with the handling robot(s), with each of the power supply stations, or even with each of the mobile connection equipment. Such communication can be done by radio, for example according to a standard known to those skilled in the art, or via wired connections connecting these components.

The power supply station 2 also comprises a retractable power supply cable 29, a first end 292 of which is connected to the power supply server 23. The second end of this retractable power supply cable 29 protrudes out of the box 21 through an outlet opening 24, and is equipped with a connection socket 291. The power supply station 2 advantageously comprises a mechanism allowing this power supply cable 29 to be able to assume two positions: a first retracted position (represented by the ), in which the power supply cable 29 is essentially placed inside the box 21 of the power supply station 2, and a deployed position in which the power supply cable 29 is retractable, at least partly , deployed outside the box 21. Advantageously, the power supply cable 29 may have a length of approximately 6 m, allowing the outlet 291 to be deployed over at least a large part of the parking space.

According to a possible solution, this mechanism can be constituted by a winder around which the electric power cable 29 is wound. Such winder solutions are well known to those skilled in the art. However, in such a case, it is necessary for the power supply cable 29 to be fully extended before using it to transmit power, in order to avoid excessive heating of the turns of the power supply cable 29 in contact with each other.

According to another embodiment, represented by the , the power supply cable 29 can be contained in the casing 21 in round trip on a substantially linear path, over the length of the casing 21. For this, the power supply cable 29 coming from the power supply server 23 can pass through a first pulley 261, connected to a carriage 260, sliding in the box 21 and connected to a first end of this box by a spring 262. This power supply cable 29 then passes through a second pulley 271, connected to a carriage 270 sliding in box 21 and linked to another end of this box 21 by a spring 272.

Thus, when a pull is exerted on the socket 291, the power supply cable 29 can deploy out of the casing 21, by exerting a pull on the

pulleys

261 and 271 having the effect of bringing the

carriages

260 and 270. On the contrary, when no traction is exerted on the socket 291, the power supply cable 29 is returned to the box 21, the

springs

260 and 270 tending to separate the

carriages

260 and 270 from one another. the other.

At the level of the outlet opening 24 of the casing 21, which allows the power supply cable 29 to come out of this casing, the casing 21 can be equipped with a clamp 241 capable of clamping the power supply cable 29. This clamp 241 thus constitutes a means of blocking the power supply cable 29, capable of blocking the power supply cable 29 at the level of the outlet opening 24. This clamp 241 is advantageously open to allow the deployment of the power supply cable. power supply 29 out of the box 21 or to allow this power supply cable 29 to be retracted into the box 21. On the other hand, it can be closed to prevent the deployment of the power supply cable 29, when this deployment does not is not desired. Similarly, the clamp 241 can be closed to hold the power supply cable 29 in the deployed configuration, and prevent its return to the box 21. This clamp 241 is preferably a motorized clamp, for example actuated by a cylinder, which can be controlled by software for managing the electric vehicle charging device.

A person skilled in the art could of course implement different variants of such a mechanism intended to make the power supply cable 29 retractable in the box 21. He could also, without difficulty, implement mechanisms making it possible to control the retraction of the power supply cable 29 in the casing 21. It is for example possible, in a particular embodiment, to replace the

springs

262 and 272 by motorization means controlling the sliding of the

carriages

260 and 270 in the casing 21.

According to a particular aspect, the invention therefore relates to a power supply station, comprising an oblong casing whose length is oriented along a longitudinal axis, this casing comprising a power supply server and a power supply cable of which a first end is connected to the power supply server and a second end, equipped with a connection socket, protrudes out of the casing through an outlet opening, this power supply station being characterized in that, between its first and its second end, the power supply cable runs around at least one pulley carried by a carriage mounted to slide in the casing, in a direction substantially parallel to the longitudinal axis of the casing, the movement of the carriage in the casing modifying the length of the path of the power supply cable in the box.

Preferably, the carriage is linked to return means driving it towards a position in which the path of the electrical supply cable in the casing is elongated.

According to another possible embodiment, the carriage is linked to drive means capable of driving it towards a position in which the path of the electrical supply cable in the box is elongated.

Advantageously, the power supply cable circulates successively, in said casing, around two pulleys each carried by a carriage mounted sliding in the casing, in a direction substantially parallel to the longitudinal axis of the casing, the movement of each of the trolleys in the casing modifying the length of the path of the power supply cable in the casing.

In this case, advantageously, each of the two carriages is linked to return means driving it towards a position in which the path of the electrical supply cable in the casing is elongated.

According to an advantageous solution, the station is equipped with blocking means capable of blocking the power supply cable at the outlet opening.

These blocking means thus make it possible to block the position of the power supply cable in the box, for example by opposing the force of the return means.

Advantageously, the longitudinal axis of the box is horizontal.

In the embodiment shown in Figures 1 and 4, the power supply station 2 is equipped with a support 28, placed in front of the outlet opening 24 of the box 21. This support 28 is able to receive the equipment mobile connection 3, as represented by the , in a position in which the socket 33 of this mobile connection equipment 3 is connected to the socket 291 of the power supply cable 29, this power supply cable 29 being in a retracted position in the box 21.

Furthermore, this support 28 is extended by inclined planes 281 extending to the ground. Thus, if the mobile connection equipment 3, attached to the power supply cable 29 by the socket 291, is placed on the ground of the parking space, as represented by the , and is pulled towards the power supply station 2 by the power supply cable 29 which retracts into this power supply station 2, this mobile connection equipment 3 can, by sliding on the inclined planes 281, come stand on the support 28, as shown in the .

The charging device according to the invention advantageously comprises a handling robot 4, capable of grasping and handling a mobile connection equipment 3.

This manipulation robot 4 is advantageously robotic equipment capable of moving on the floor of the car park. For this, it is advantageously equipped with wheels. In the embodiment represented, the manipulation robot 4, which is represented in particular by FIGS. 6 to 8 and 18 to 20, thus comprises two

motorized drive wheels

411 and 412. It also comprises two

non-drive wheels

413 and 414, crazy to allow the handling robot 4 great freedom of maneuver. The characteristics of the motorization of wheels such as the

motorized driving wheels

411 and 412 are well known to those skilled in the art, and already implemented in various configurations to allow the movement of motorized robots. They are therefore not further described in the present application.

To allow the autonomous movement of the manipulation robot 4, the motors actuating these

motorized driving wheels

411 and 412 are controlled by an electronic card implementing software which chooses the movements to be carried out by the manipulation robot 4 according to movement instructions. and geolocation information of the manipulation robot 4, which can be given for example by geolocation equipment, inertial platforms, accelerometers, or other equivalent equipment. Furthermore, this software can take into account other information given by various sensors carried by the handling robot 4, such as for example cameras, radars, lidars, or contact or proximity detectors located at the edges of the robot. Such software, implementing algorithms allowing the autonomous movement of a robot to be guided, are already known to those skilled in the art and will not be further described.

According to a particularly advantageous characteristic of the invention, the handling robot 4 is designed to withstand crushing, including crushing by a wheel of a motor vehicle.

For this, the handling robot 4 comprises a housing 40 having a generally flat shape. Thus, this box 40 has, in the preferred embodiment, a height less than or equal to 10 cm. Because of this low height, if a vehicle were to accidentally roll over the handling robot 4, it would tend to crush it against the ground rather than throw it. Moreover, the fact of rolling over the handling robot 4 would only generate a slight obstacle for the vehicle that would not affect the driving of the vehicle in a detrimental or dangerous manner.

The box 40 comprising the various components of the manipulation robot 4 is preferably dimensioned very robustly, with internal reinforcements, so that it is capable of withstanding being crushed against the ground by a weight of several hundred kilos.

In the event that the handling robot 4 is crushed by a heavy weight, in particular by a wheel of a motor vehicle, the mounting of the wheels of the handling robot 4 presents a particular difficulty. Thus, the mounting of wheels making it possible to support a weight of several hundred kilos is very difficult to achieve, and requires the use of parts, and in particular rotation axes, the dimensions of which entail significant bulk.

To solve this problem, the inventors imagined mounting the wheels of the handling robot 4 on suspension devices allowing, when a weight is applied to the handling robot 4, that the wheels retract inside the housing 40 of the handling robot 4. Preferably, when the weight applied to the handling robot 4 exceeds a predetermined limit weight, the wheels can retract completely, so that the housing 40 of the handling robot 4 is directly in support On the ground. In this way, the weight applied to the handling robot 4 is directly supported by the housing 40, and does not cause any mechanical stress on the wheels of the handling robot 4, their axles or the drive system.

Thus, the represents the assembly of the drive wheel 411 in the housing 40. This drive wheel 411 is mounted on a pivoting support 4111 which, when no abnormal weight is exerted on the handling robot 4, causes the wheel 411 to protrude under the handling robot. manipulation 4. On the other hand, when an abnormal weight is exerted on the manipulation robot 4, this weight causes the deformation of a suspension system linked to the pivoting support 4111, so that this pivoting support 4111 moves the wheel 411 in l retracting entirely into a chamber 4110 which contains the wheel 411. The wheel 411 then no longer protrudes under the handling robot 4, which is then in contact with the ground. The abnormal weight is then exerted only on the manipulation robot 4, and does not risk damaging the wheel 411. The other drive wheel 412 is advantageously mounted in the same way.

Likewise, the represents the mounting of the idler wheel 413 in the housing 40. This idler wheel 413 is mounted on a pivoting support 4131 which, when no abnormal weight is exerted on the handling robot 4, causes the wheel 413 to protrude under the handling robot manipulation 4. On the other hand, when an abnormal weight is exerted on the manipulation robot 4, this weight causes the deformation of a suspension system linked to the pivoting support 4131, so that this pivoting support 4131 moves the wheel 413 in l retracting entirely into a chamber 4130 which contains the wheel 413. The wheel 413 then no longer protrudes under the handling robot 4, which is then in contact with the ground. The abnormal weight is then exerted only on the manipulation robot 4, and does not risk damaging the wheel 413. The other idler wheel 414 is advantageously mounted in the same way.

Furthermore, in the embodiment shown, the manipulation robot 4 has a turret 42 protruding by a few centimeters from the upper surface of the manipulation robot 4. This turret 42 can advantageously comprise means for detecting the environment, such as lidar, radar or camera. Such equipment is fragile, and it should be avoided that, in the event of crushing of the manipulation robot 4 by a significant weight, in particular by a wheel of a motor vehicle, this turret 42 does not undergo excessive mechanical stresses. For this, as represented by the , this turret 42 is movably mounted in a chamber 420, into which it can retract. When no abnormal weight is exerted on this turret 42, return means located in the chamber 420 maintain it in its position represented by the , in which the turret 42 protrudes above the casing 40 of the manipulation robot 4. On the other hand, when an abnormal weight is exerted on this turret, the latter retracts entirely into the chamber 420, by compressing the means of reminder.

Thus, according to a particular aspect of the invention, the latter also relates to an autonomous mobile robot comprising a casing fitted with wheels enabling it to be moved, the wheels being mounted, in chambers of the casing, on suspension systems holding the wheels to the at least partially outside said chambers, when the robot is not crushed by a weight greater than a predetermined value, this robot being characterized in that the suspensions are dimensioned such that, when the robot is crushed by a greater weight at a predetermined value, the wheels retract into the chambers so that the casing comes into contact with the ground.

Advantageously, the case has a generally flat shape, and a thickness of less than 10 cm.

According to an advantageous embodiment, at least some of the wheels are motorized driving wheels.

According to an advantageous embodiment, at least some of the wheels are directional wheels.

According to an advantageous embodiment, at least some of the wheels are idler wheels.

Advantageously, the case is dimensioned so that it can withstand a crushing weight of several hundred kilos.

According to another particular aspect of the invention, the latter also relates to an autonomous mobile robot comprising a casing equipped with a turret, this turret being mounted in a chamber of the casing, and held at least partially outside of said chamber by return means, when the turret is not crushed by a weight greater than a predetermined value, this robot being characterized in that the return means are dimensioned such that, when the turret is crushed by a weight greater than a predetermined value, the turret retracts into said chamber.

The manipulation robot 4 is designed to grasp, manipulate, move a mobile connection equipment similar to the mobile connection equipment 3. For this, as shown in the , the housing 40 of this manipulation robot 4 advantageously has a U-shape, delimiting a storage location 43 whose dimensions correspond to those of the mobile connection equipment 3.

To manipulate the mobile connection equipment 3, the manipulation robot 4 comprises two

telescopic arms

431 and 432, placed on the periphery of the storage location 43. These

telescopic arms

431 and 432 are equipped with grippers, respectively 4310 and 4320, capable of grasping a mobile connection equipment 3 and holding it in the storage location, or lifting it, as represented for example by the in order to position it, for example, on the support 28 of the power supply station 2 or in contact with an inductive charging interface of a motor vehicle.

These

telescopic arms

431 and 432 are advantageously formed of rods that are movable relative to each other, allowing movement of the

clamps

4310 and 4320, and where appropriate of the mobile connection equipment 3 held by these clamps, in a substantially vertical direction. .

These telescopic arms are thus movable between a folded configuration, represented for example by FIGS. 6 and 7, in which the

clamps

4310 and 4320, capable of holding a mobile connection equipment 3, are held in the storage location 43, and a deployed configuration, represented in particular by FIGS. 8 and 16, in which the

clamps

4310 and 4320 are held by the

telescopic arms

431 and 432 at a distance above the storage location 43. In the folded configuration of the

telescopic arms

431 and 432, the handling robot 4 has a compact shape and a low height. On the contrary, in the deployed configuration of these

telescopic arms

431 and 432, the robot can lift mobile storage equipment 3 to a height much greater than the height of its casing 40. The handling robot 4 is then much more easily visible for surrounding users.

According to an advantageous embodiment of the invention, the handling robot 4 is configured to move while maintaining the

telescopic arms

431 and 432 in the deployed configuration, even when it is not handling or moving a mobile connection equipment 3, when it circulates in certain areas of the car park where users are likely to move. The handling robot 4 thus benefits from better visibility in the eyes of parking lot users and can therefore move around in a safe manner.

According to a particularly advantageous feature, the handling robot 4 comprises an induction charging interface, allowing it to electrically supply its accumulators. Advantageously, this inductive charging interface is located in the part of the casing 40 which forms the lower wall of the storage location 43. Thus, when a mobile connection equipment such as the mobile connection equipment 3 is carried by a manipulation robot 4 in its storage location 43, while it is electrically powered by a power supply cable 29, this mobile connection equipment 3 is capable of generating a magnetic field transmitting energy to the interface of inductive charging of the handling robot 4, and allowing the latter, for example, to supply its motors or to charge its batteries.

Thus, the manipulation robot 4 can be electrically powered during its operations of manipulation and movement of a mobile connection equipment 3. Such a characteristic can make it possible to increase the duration of autonomy of the batteries of the manipulation robot 4 Provision may even be made, in certain embodiments, for this mode of powering the manipulation robot 4 to be an exclusive mode, and for the manipulation robot 4, when it needs to be electrically powered, to do so by charging a mobile connection equipment 3 powered electrically by a power supply cable 29.

It is also possible, in an alternative embodiment, that the handling robot 4 does not include an inductive charging interface but has a power socket allowing it to connect, autonomously, to a socket dedicated power supply.

Thus, according to a particular aspect of the invention, the latter also relates to an autonomous mobile robot having a storage location capable of containing a mobile connection equipment comprising an electrically powered inductive coil, this robot being characterized in that it comprises an inductive charging interface comprising a coil able to generate an induced current when it undergoes a magnetic field, this inductive charging interface being located close to said storage location, so as to be able to receive a magnetic field produced by a inductive coil of a mobile connection device placed in said storage location.

Preferably, this autonomous mobile robot is capable of transporting said mobile connection equipment to said storage location.

Advantageously, this autonomous mobile robot has arms capable of lifting said mobile connection equipment above said storage location.

Figures 12 and 13 schematically represent a motor vehicle 5 equipped with an induction charging interface 50 compatible with the mobile connection equipment 3.

This inductive charging interface 50 is, in a known manner, a plate comprising an electric winding, which is placed on the underside of the vehicle. This electric winding, when it is crossed by a magnetic field generated by the mobile connection equipment 3, generates an induced current which can be used for charging the batteries of the motor vehicle 5.

The inductive charging interface 50 of the motor vehicle 5 is advantageously equipped with holding means capable of holding the mobile connection equipment 3, when the latter is placed opposite the inductive charging interface of the vehicle.

According to one possible embodiment, these holding means can be constituted by mechanical hooks carried by the motor vehicle 5. The unlocking of these hooks can advantageously be controlled by the vehicle, in order to let them fall back to the ground, under the effect of gravity, connection mobile equipment 3.

According to another possible embodiment, the maintenance of the mobile connection equipment 3 on the inductive charging interface of the vehicle can be carried out by magnetic means, such as for example by electromagnets, included in the equipment mobile connection 3, which, when they are electrically powered, generate a continuous magnetic field capable of maintaining the mobile connection equipment 3 in contact with a ferromagnetic mass of the inductive charging interface 50 or of the chassis of the motor vehicle 5 .

According to a particular embodiment, the inductive coil 35 of the mobile connection equipment 3 can be powered by an electric current having both a DC component, allowing the inductive coil 35 to generate a DC component of a magnetic field , making it possible to generate a force maintaining the mobile connection equipment 3 against a ferromagnetic mass of the charging interface by induction 50 or of the chassis of the motor vehicle 5, and an alternating component, allowing the magnetic field generated by the inductive coil 35 has an AC component generating induced currents in the coil of the vehicle's induction charging interface. This inductive coil 35 of the mobile connection equipment 3 then itself constitutes the electromagnet making it possible to ensure the maintenance of the mobile connection equipment 3 against the charging interface by induction 50.

Here again, the magnetic holding means of the mobile connection equipment 3 against the inductive charging interface of the vehicle can be deactivated, by cutting off the supply to the coils generating this holding, or at least the DC component of this supply , in order to let the mobile connection equipment 3 fall to the ground.

It should be noted that the inductive charging interface 50 of the motor vehicle 5 can be installed under the underside of the vehicle during the manufacture of the latter or, in other cases, be installed on a vehicle subsequently, and connected to its electrical charging system.

Thus, according to a particular aspect of the invention, the latter also relates to mobile connection equipment for an electric vehicle charging device, this mobile connection device being capable of being electrically powered by a power cable, this equipment mobile connection device comprising a coil capable, when it is electrically powered, of generating an alternating magnetic field able to perform a charge by induction, this mobile connection device being characterized in that it comprises at least one electromagnet capable of securing the mobile connection device to a ferromagnetic ground.

According to a particularly advantageous embodiment, this electromagnet is constituted by said coil, which is electrically powered by a current having both a DC component and an AC component, so as to generate a magnetic field having both a component continuous and an alternating component.

In some configurations, it may be useful to store several mobile connection equipment 3 of a car park. The thus shows a storage support 6 capable of supporting several mobile connection equipment 3. This storage support 6 has several storage slots 61, aligned one above the other at heights allowing the handling robot 4 to place a mobile connection equipment 3 in each of these locations, or to remove it.

In the embodiment represented, these storage slots are presented as sockets in the form complementary to the socket 33 of the mobile connection equipment 3.

It should be noted that the lowest located storage location 61 can be constituted by an electrically powered socket. In this way, the handling robot 4 can connect a mobile connection equipment 3 to this location while keeping it in its storage location 43. If the handling robot 4 includes an inductive charging interface, it can thus be supply energy through the mobile connection equipment 3 electrically connected.

An electric vehicle charging device according to one embodiment of the invention is particularly advantageous when it is deployed on a plurality of parking spaces of the same parking lot. The thus represents, schematically, a parking lot in which three

parking spaces

101, 102 and 103 are deployed.

In a car park, all the parking spaces intended to allow the recharging of motor vehicles are equipped with power supply stations 2. The power supply stations 2 placed at the edge of neighboring parking spaces are preferably aligned next to each other so as to form a continuous plinth, along several parking spaces. This plinth advantageously allows the circulation of the power supply network supplying the various power supply stations 2.

The parking lot is equipped with a number of connecting mobile equipment 3 less than the number of power supply stations 2. Indeed, in a parking lot, it is normally not necessary for all the parked vehicles to be charged at the same time. The same mobile connection equipment 3 can then be associated with an electrical supply station 2, for a given time, to charge a vehicle placed on the parking space associated with it, and then be moved to be associated with a another power supply station 2, in order to charge a vehicle placed on another parking space.

A single handling robot 4 can ensure the movements of a plurality of mobile connection equipment 3. Thus, by way of example, a parking lot comprising thirty parking spaces equipped with power supply stations 2, can be equipped with eight mobile connection equipment 3 and a single handling robot 4. This equipment can allow the charging of electric vehicles on each of the thirty parking spaces.

The equipment of the car park, to allow the charging of electric vehicles, is thus restricted. Indeed, the power supply stations 2 are relatively inexpensive equipment, and the fact of equipping each of the parking spaces with them does not generate excessive cost. The mobile connection equipment 3, comprising windings, is more expensive equipment. However, due to their smaller number than the number of equipped parking spaces, the cost of equipping the entire park remains moderate. Finally, the handling robot 4 is expensive equipment. However, a single handling robot 4 being necessary to equip the entire fleet, the overall installation cost remains measured.

The solution according to the invention thus makes it possible to equip a car park to allow the charging of electric vehicles therein, subject to a measured investment. Of course, in other configurations, the same parking lot can be equipped with several handling robots 4, in particular if there is a greater number of parking spaces equipped with power supply stations 2.

The following describes the sequence of use of a vehicle charging device according to one embodiment of the invention, to recharge a vehicle coming to park in an equipped parking space.

When a vehicle 5 equipped with an inductive charging interface 50 comes to park in an equipped parking space, an optical recognition system, associated with the parking lot, identifies the vehicle, in particular by reading its license plate. Following this identification, the car park system makes contact with a mobile terminal of the vehicle or of its user, such as the user's telephone, in order to offer him to order a charge of the vehicle. If the user controls an electrical charge of his vehicle, the parking lot management system controls the implementation of the charging device.

When the implementation of the charging device is ordered, a handling robot 4 present in the car park will fetch a mobile connection equipment 3. It can thus take a mobile connection equipment 3 which is placed on the support 28 of a supply station 2 and which is not used, or a mobile connection equipment 3 which is stored on a storage support 6. This mobile connection equipment 3 is then placed in the storage location 43 of the manipulation robot 4 in order to be moved.

After charging a mobile connection equipment 3, the robot moves by transporting this mobile connection equipment 3 to the support 28 of the supply station 2 associated with the location on which the vehicle to be loaded is located, such as the represents the . He then approaches the support 28 sufficiently to place the mobile connection equipment 3 on this support 28, and to connect the socket 33 of the mobile connection equipment 3 to the socket 291 of the supply station 2, as shown. the .

It should be noted that the robot 10 advantageously has a shape complementary to that of the support 28 which allows it, when it approaches this support 28, to center it perfectly on this support. This centering makes it possible to ensure a correct connection of the socket 33 of the mobile connection equipment 3 on the socket 291 of the supply station 2. During this connection, the socket 33 of the mobile connection equipment 3 and the socket 291 of the supply station 2 can advantageously be locked to each other.

Once this connection has been made, the handling robot 4 moves away from the power supply station 2, as represented by the , driving the mobile connection equipment 3 and the socket 33 which is connected to it. This distance causes the deployment of the power supply cable 29 out of the power supply station 2.

While moving, the manipulation robot 4 passes under the chassis of the motor vehicle 5 to be loaded, as represented by the . He then positions himself below the induction charging interface 50 of this motor vehicle 5, and raises the mobile connection equipment 3 in order to place it facing this induction charging interface 50 of the vehicle. A holding mechanism is then actuated, holding the mobile connection equipment 3 against the inductive charging interface 50.

The manipulation robot 4 then lets go of the mobile connection equipment 3, and can move away to leave the parking space, as represented by the . The mobile connection equipment 3 being in place against the inductive charging interface 50, the supply server of the electrical supply station 2 can supply it electrically in order to charge the motor vehicle 5.

When the motor vehicle 5 is charged, the mechanism for holding the mobile connection equipment 3 on the induction charging interface 50 of the motor vehicle 5 can be deactivated and release the mobile connection equipment 3 which then falls. on the ground, as represented by the .

At this time, the return means controlling the retraction of the cable 29 into the electric charging station 2 can be activated. By retracting the power supply cable 29, they attract the mobile connection equipment 3 until it is placed on the support 28 of the power supply station 2, as represented by the . The mobile connection equipment 3 can then remain locked on this support 28 until a new use.

According to another possible solution, the manipulation robot 4 can enter the mobile connection equipment 3 placed on the support 28. In this case, the socket 33 of the mobile connection equipment 3 and the socket 291 of the station of 2 are unlocked from each other, and the robot can take the mobile connection equipment 3. It can for example go and place it on the storage support 6, as represented by the , to wait for a new use.

Figures 21 and 22 show a mobile connection equipment 7, which can be implemented in the electric vehicle charging device of the . This mobile connection equipment 7 advantageously has dimensions and a shape allowing it to be transported by the handling robot 4 in the same way as the mobile connection equipment 3. It also comprises a socket complementary to the socket the socket 291 of the supply station 2, allowing it to be connected to the power supply cable 29. This mobile connection equipment 7 also has a connection socket 71, suitable for being connected to a connection socket of a vehicle which would not include an inductive charging interface.
As shown in , the manipulation robot 4 can manipulate the mobile connection equipment 7, in the same way as the mobile connection equipment 3, in order to connect it to an electrical supply cable 29 and to hand it to a user, to that he can plug in his vehicle.
