Description

Title of the invention: Occlusion device and method for controlling such an occultation device

[0001] The present invention relates to a concealment device and a method for controlling such a concealment device.

[0002] Generally, the present invention relates to the field of occultation devices comprising a motorized drive device setting a screen in motion, between at least a first position and at least a second position.

[0003] A motorized drive device comprises an electromechanical actuator of a movable closing, concealing or sun protection element, such as a blind or any other equivalent material, hereinafter called a screen.

[0004] Document US-B-11 203 899 is already known, which describes a screening device comprising a screen, a screen holding device, a load bar, a motorized drive device and an electrical power supply device. A first end of the screen is arranged at the screen holding device and a second end of the screen is fixed to the load bar. The motorized drive device comprises an electromechanical actuator configured to move the screen.

[0005] The electrical energy supply device comprises a main battery arranged at the screen holding device and electrically connected to the electromechanical actuator, a secondary battery arranged at the charging bar and a photovoltaic solar panel arranged at the charging bar and making it possible to recharge the secondary battery. The secondary battery makes it possible to recharge the main battery, either by induction, only when the screen is in a retracted configuration, that is to say the charging bar is close to the screen holding device, or using conductive wires woven into the screen. The device also comprises a charging connector.

[0006] The charging connector is configured to be electrically connected to an external electrical power supply source to recharge the secondary battery, in particular when the photovoltaic solar panel does not provide enough electrical power. In other words, the charging connector provides a backup charging solution to recharge the secondary battery.

[0007] However, this emergency charging solution is not satisfactory in the common case where the main battery has a higher capacity than the secondary battery. Indeed, in this case, first recharging the secondary battery with the external electrical power supply via the connector of recharging, then recharging the main battery with the secondary battery, only partially recharges the main battery. On the other hand, the recharging efficiency is quite low due to the successive energy transfers, particularly in the case of using wireless energy transfers.

[0008] The primary battery is generally associated with an electromechanical actuator and is therefore sized to operate the actuator independently for a certain number of cycles or a certain duration before requiring manual recharging. On the contrary, the rather restricted space at the charging bar constrains the dimensions and therefore the capacity of the secondary battery. The latter may therefore end up having a much lower capacity than that of the primary battery, generally at least three or four times lower than that of the primary battery. Economic and ecological balances also require limiting the maximum capacity of the secondary battery.

[0009] The present invention aims to solve this drawback and to propose a concealment device by means of which it is possible to carry out a more efficient emergency recharge of the concealment device using an external electrical power supply source, and in a manner which is simple to implement for a user of the concealment device.

[0010] To this end, the invention relates to a screening device comprising: - a screen, - a holding device, for holding the screen, a first end of the screen being attached to the screen holding device, - a load bar, a second end of the screen being fixed to the load bar, - an electromechanical actuator, configured to move the screen and the load bar along a movement axis between a retracted configuration of the screen and a deployed configuration of the screen, - an electrical power supply device, comprising at least: • a main battery, attached to the screen holding device and electrically connected to the electromechanical actuator, • a first electrical connection element, attached to the load bar, • a secondary battery, attached to the charging bar and electrically connected to the first electrical connection element, • a second electrical connection element, secured to the holding device and electrically connected to the main battery, the second electrical connection element being configured to establish an electrical connection with the first electrical connection element electrical connection when the screen is in the retracted configuration, • a photovoltaic solar panel, attached to the charging bar and electrically connected to the secondary battery, • a charging connector, secured to the charging bar and configured to be electrically connected to an external electrical power supply source, and • a conductive element connecting the charging connector and the first electrical connection element.

[0011] By virtue of the invention, the charging connector is electrically connected to the main battery, which allows it to be recharged from the external electrical power supply source without first recharging the secondary battery. In addition, the charging connector is arranged at the charging bar, which facilitates the connection of the external electrical power supply source by a user of the occulting device, in comparison with a charging connector arranged at the screen holding device.

[0012] According to other advantageous aspects of the invention, the occultation device comprises one or more of the following characteristics, taken individually or in all technically possible combinations:

[0018] - The set of two insulated gate field effect transistors is configured to allowing electric current to flow from the secondary battery to the first electrical connection element when the charging connector is not electrically connected to the external electrical power supply source, and preventing electric current to flow from the secondary battery to the first electrical connection element when the charging connector is electrically connected to the external electrical power supply source.

[0019] - The electronic means comprise a regulating member, such as a re voltage regulator and a current limiter, and a diode, the regulating member and the diode being mounted in parallel with the set of two insulated gate field effect transistors, the diode allowing current flow from the charging connector and the first electrical connection element to the secondary battery and preventing current flow in the opposite direction.

[0022] - The electrical energy supply device further comprises an element auxiliary conductor connecting the charging connector and the first electrical connection element in parallel with the conductive element and allowing communication data to be transferred between the charging connector and the first electrical connection element.

[0024] According to other advantageous aspects of the invention, the method for controlling a concealment device comprises one or more of the following characteristics, taken in isolation or in all technically possible combinations:

[0027] - The remote electronic control unit detects the electrical connection of the external electrical power source to the charging connector by detecting a voltage delivered by the external electrical power source to the charging connector.

[0028] This method of controlling a concealment device induces the same advantages as those mentioned above with regard to the concealment device of the invention.

[0029] The invention will appear more clearly on reading the description which follows, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0030] [Fig-1] [Fig.l] is a schematic cross-sectional view of an installation comprising a concealment device according to one embodiment of the invention.

[0031] [Fig.2] [Fig.2] is a schematic perspective view of the installation illustrated in [Fig.l].

[0032] [Fig.3] [Fig.3] is a schematic sectional view of an electromechanical actuator of the installation illustrated in Figures 1 and 2, along a sectional plane passing through an axis of rotation of an output shaft of the electromechanical actuator.

[0033] [Fig.4] [Fig.4] is a schematic front view of a portion of the installation illustrated in Figures 1 and 2, with a screen of the installation in a deployed configuration.

[0034] [Fig.5] [Fig.5] is a schematic perspective view of the installation illustrated in Figures 1, 2 and 4, with the installation screen in a retracted configuration.

[0035] [Fig.6] [Fig.6] is a schematic representation of an electrical power supply device belonging to the concealment device of the installation of figures 1, 2, 4 and 5.

[0036] [Fig.7] [Fig.7] is a schematic representation of an electrical power supply device belonging to the concealment device of an installation, the concealment device being in accordance with another embodiment of the invention.

[0037] [Fig.8] [Fig.8] is a schematic representation of an electrical power supply device belonging to the concealment device of an installation, the concealment device being in accordance with another embodiment of the invention.

[0038] First of all, with reference to Figures 1 and 2, an installation 6 is described, comprising a closing, concealing or solar protection device 3 according to a first embodiment of the invention, installed in a building B comprising an opening 1, window or door. This installation 6 is equipped with a screen 2 belonging to the closing, concealing or solar protection device 3, in particular a motorized blind.

[0039] The closing, concealing or sun protection device 3 is hereinafter called the “concealing device”. The concealing device 3 comprises the screen 2.

[0040] The blackout device 3 may comprise a blind, in particular a canvas, a roller blind, a pleated blind or a slatted blind. The present invention applies to all types of blackout device. The following example corresponds to a roller blind.

[0041] The occulting device 3 comprises a winding tube 4 and a motorized drive device 5. The motorized drive device 5 comprises an electromechanical actuator 11 illustrated in [Fig.3].

[0042] The screen 2 of the occulting device 3 is wound onto the winding tube 4 driven by the motorized drive device 5 or unwound from the winding tube 4.

[0043] The screen 2 extends along a displacement axis Z when it is unrolled. The Z axis is also the displacement axis Z of the screen under the effect of the motorized drive device 5. The displacement axis Z is vertical in the example.

[0044] The screen 2 of the occultation device 3 is a closing, occultation and / or solar protection screen, winding and unwinding around the winding tube 4, the internal diameter of which is greater than the external diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, during the assembly of the occultation device 3.

[0045] Advantageously, the concealment device 3 comprises a holding device 9, 23.

[0046] Advantageously, the holding device 9, 23 may comprise two supports 23. A support 23 is arranged at each end of the winding tube 4, in an assembled configuration of the concealing device 3.

[0047] Thus, the winding tube 4 is held by means of the supports 23. Only one of the supports 23 is visible in Figures 1 and 5. The supports 23 make it possible to mechanically connect the occultation device 3 to the structure of the building B. In the example, the supports 23 make it possible to mechanically connect the occultation device 3 to a ceiling of the building B. Alternatively, the supports 23 make it possible to mechanically connect the occultation device 3 to a wall of the building B located above the opening 1, or to the uprights of the window or door forming the opening 1.

[0048] Advantageously, the holding device 9, 23 may comprise a box 9. Furthermore, the winding tube 4 and at least part of the screen 2 are housed inside the box 9, in the assembled configuration of the occulting device 3.

[0049] Generally, the box 9 is arranged above the opening 1, or in the upper part of the opening 1.

[0050] Here and as illustrated in [Fig. 1], the supports 23 are also housed inside the box 9.

[0051] Advantageously, the box 9 comprises two cheeks 10, as illustrated in [Fig.2]. A cheek 10 is arranged at each end of the box 9, in the assembled configuration of the concealing device 3.

[0052] As a variant, shown in [Fig.2], the winding tube 4 is held by means of the box 9, in particular by means of the cheeks 10 of the box 9, without using supports, such as the supports 23 mentioned above.

[0053] The electromechanical actuator 11 is, for example, of the tubular type. This makes it possible to rotate the winding tube 4 around an axis of rotation X, so as to unwind or wind the screen 2 of the occulting device 3.

[0054] Thus, the screen 2 can be rolled up and unrolled on the winding tube 4. In the mounted state, the electromechanical actuator 11 is inserted into the winding tube 4.

[0055] The occulting device 3 further comprises a weighted load bar 8 for exerting tension on the screen 2. The tension generated by the load bar 8 on the screen 2 is directed along the displacement axis Z.

[0056] Advantageously, as seen in [Fig.4], the load bar 8 comprises a first end 8a and a second end 8b. The second end 8b is opposite the first end 8a.

[0057] The roller blind, which forms the occultation device 3, comprises a fabric, forming the screen 2 of the roller blind 3. A first end 2b of the screen 2, in particular the upper end of the screen 2, called the high end, in the assembled configuration of the occultation device 3, is fixed to the winding tube 4, in other words is attached to the holding device 9, 23. In addition, a second end 2c of the screen 2, in particular the lower end of the screen 2, called the low end, in the assembled configuration of the occultation device 3, is fixed to the load bar 8. The load bar 8 is thus suspended under the screen 2 at its second end 2c.

[0058] Here, the canvas forming the screen 2 is made from a textile material.

[0059] The screen 2 is movable under the action of the electromechanical actuator 11 and can be moved between a rolled-up configuration, or a retracted configuration, or a high position, and a low position.

[0060] Whatever the embodiment, the first end 2b of the screen 2 is arranged at the level of the holding device 9, 23, in the sense that this first end 2b remains above the opening 1 in the assembled configuration of the concealing device 3.

[0061] In the case of a roller blind, the high position corresponds to a predetermined high end-of-travel position, preferably defined by the user.

[0062] A retracted configuration corresponds to the loading bar 8 of the screen 2 resting against an edge of a box 9 of the roller blind 3, or to a configuration where the loading bar 8 is close to the holding device 9, 23. It may, in particular, be considered that the loading bar 8 is close to the holding device 9, 23 when the loading bar 8 is located above the opening 1 and in particular above the high position.

[0063] In the case of a roller blind, the low position corresponds to a predetermined low end-of-travel position, or to the loading bar 8 of the screen 2 resting against a threshold 7 of the opening 1, or even to the complete unrolling of the screen 2. We speak of deployed configuration for a configuration where the loading bar 8 is further from the holding device 9, 23 in the direction of the low position than in the retracted configuration. In other words, on the deployment stroke of the screen between the low position and the retracted configuration, when the screen 2 is not in configuration retracted, it is in the deployed configuration.

[0064] Advantageously, the motorized drive device 5 is controlled by a control unit. The control unit may be, for example, a local control unit 12 or a central control unit 13.

[0065] Advantageously, the local control unit 12 can be connected, by wired or wireless connection, with the central control unit 13.

[0066] Advantageously, the central control unit 13 can control the local control unit 12, as well as other similar local control units distributed throughout the building.

[0067] The motorized drive device 5 is preferably configured to execute the commands for unrolling or rolling up the screen 2 of the occulting device 3, which can be issued, in particular, by the local control unit 12 or the central control unit 13.

[0068] The installation 6 comprises either the local control unit 12, or the central control unit 13, or the local control unit 12 and the central control unit 13.

[0069] The electromechanical actuator 11 belonging to the installation 6 of FIGS. 1 and 2 will now be described in more detail and with reference to [Fig. 3].

[0070] The electromechanical actuator 11 comprises an electric motor 16. The electric motor 16 comprises a rotor and a stator, not shown, positioned coaxially around the axis of rotation X of the winding tube 4 in the mounted configuration of the motorized drive device 5.

This electronic control unit 15 is capable of putting the electric motor 16 of the electromechanical actuator 11 into operation, and, in particular, of allowing the electric motor 16 to be supplied with electrical energy.

[0072] Thus, the electronic control unit 15 controls, in particular, the electric motor 16, so as to open or close the screen 2, as described previously.

[0073] The control means of the electromechanical actuator 11 comprise hardware and / or software means.

[0074] By way of non-limiting example, the hardware means may comprise at least one microcontroller, not shown.

[0078] Advantageously, the electronic control unit 15, the local control unit 12 and / or the central control unit 13 may be in communication with a weather station arranged inside the building B or remote outside the building B, including, in particular, one or more sensors that may be configured to determine, for example, a temperature, a brightness, or even a wind speed, in the case where the weather station is remote outside the building B.

[0079] Advantageously, the electronic control unit 15, the local control unit 12 and / or the central control unit 13 can also be in communication with a server 28, as illustrated in [Fig.2], so as to control the electromechanical actuator 11 according to data made available remotely via a communication network, in particular an internet network which can be connected to the server 28.

[0080] The electronic control unit 15 can be controlled from the local control unit 12 and / or central control unit 13.

The control keyboard of the local control unit 12 or central control unit 13 comprises one or more selection elements 14 and, optionally, one or more display elements 34.

[0081] By way of non-limiting examples, the selection elements may comprise push buttons and / or sensitive keys. The display elements may comprise light-emitting diodes and / or an LCD (acronym for the English term “Liquid Crystal Display”) or TFT (acronym for the English term “Thin Film Transistor”) display. The selection and display elements may also be implemented using a touch screen.

[0082] The local control unit 12 and / or central control unit 13 comprises at least one second communication module 36.

[0083] Thus, the second communication module 36 of the local control unit 12 or central control unit 13 is configured to transmit, in other words emit, control orders, in particular by wireless means, for example radioelectric, or by wired means.

[0084] Furthermore, the second communication module 36 of the local control unit 12 or central 13 can also be configured to receive, in other words receives, control orders, in particular via the same means.

[0085] The second communication module 36 of the local control unit 12 or central control unit 13 is configured to communicate, in other words communicates, with the first communication module 27 of the electronic control unit 15.

[0086] Thus, the second communication module 36 of the local control unit 12 or central control unit 13 exchanges control orders with the first communication module 27 of the electronic control unit 15, either in a unidirectional manner or in a bidirectional manner.

[0087] Advantageously, the local control unit 12 is a control point, which may be fixed or mobile. A fixed control point may be a control box intended to be fixed on a facade of the wall of the building B or on a face of a fixed frame of a window or a door. A mobile control point may be a remote control, a smartphone or a tablet.

[0088] Advantageously, the local control unit 12 and / or central control unit 13 further comprises a controller 35.

[0089] The motorized drive device 5, in particular the electronic control unit 15, is preferably configured to execute movement control orders, in particular closing and opening, of the screen 2 of the occulting device 3. These control orders can be issued, in particular, by the local control unit 12 or by the central control unit 13.

[0090] The motorized drive device 5 can be controlled by the user, for example by receiving a control command corresponding to pressing the or one of the selection elements 14 of the local control unit 12 or central control unit 13.

[0091] The motorized drive device 5 can also be controlled automatically, for example by receiving a control command corresponding to at least one signal from at least one sensor and / or a signal from a clock of the electronic control unit 15, in particular from the microcontroller.

[0093] Here, the casing 17 of the electromechanical actuator 11 is of cylindrical shape, in particular of revolution around the axis of rotation X.

[0094] In an exemplary embodiment, the casing 17 is made of a metallic material.

[0097] The electrical energy supply device 31 comprises at least one main battery 24. The electromechanical actuator 11 is supplied with electrical energy, in other words is configured to be supplied with electrical energy, by means of the main battery 24.

[0098] Advantageously, the electromechanical actuator 11 comprises the main battery 24.

[0099] Thus, and as visible in [Fig.3], the main battery 24 is arranged inside the casing 17, in particular in the assembled configuration of the electromechanical actuator 11.

[0100] As a variant, not shown, the main battery 24 can be arranged at the level of the box 9 of the concealment device 3. The main battery 24 can thus be arranged inside or outside the box 9. The main battery 24 can also be arranged inside the winding tube 4, while being outside the casing 17.

[0116] The winding tube 4 is rotated about the axis of rotation X and the casing 17 of the electromechanical actuator 11 while being supported by means of two pivot connections. The first pivot connection is made at a first end of the winding tube 4 by means of a crown, not shown, inserted around a first end 17a of the casing 17 of the electromechanical actuator 11. The crown thus makes it possible to produce a bearing. The second pivot connection, not shown, is made at a second end of the winding tube 4.

[0117] Advantageously, the electromechanical actuator 11 further comprises a torque support 21, which may also be called an “actuator head”.

[0123] Advantageously, the torque support 21 comprises a first part 21a and a second part 21b.

[0124] Advantageously, the first part 21a of the torque support 21 is configured to cooperate, in other words cooperates, with the casing 17 of the electromechanical actuator 11, in particular in the assembled configuration of the electromechanical actuator 11. Furthermore, the second part 21b of the torque support 21 is configured to cooperate, in other words cooperates, with the holding device 9, 23, in particular in an assembled configuration of the electromechanical actuator 11 in the occulting device 3.

[0125] Thus, the production of the torque support 21 comprising the first and second parts 21a, 21b in a single piece makes it possible to improve the rigidity of the torque support 21.

[0126] Advantageously, at least a portion of the first part 21a of the torque support 21 is of generally cylindrical shape and is arranged inside the casing 17 of the electromechanical actuator 11, in the assembled configuration of the electromechanical actuator 11.

[0127] Advantageously, an outer diameter 0212 of at least a portion of the second part 21b of the torque support 21 is greater than an outer diameter 017 of the casing 17 of the electromechanical actuator 11.

[0128] Advantageously, the torque support 21 comprises a stop 33 configured to cooperate, in other words which cooperates, with the casing 17, at the level of the first end 17a of the casing 17, in the assembled configuration of the electromechanical actuator 11.

[0129] Thus, the stop 33 of the torque support 21 makes it possible to limit the sinking of the first part 21a of the torque support 21 into the casing 17, in the direction of the axis of rotation X.

[0130] Furthermore, the stop 33 of the torque support 21 delimits the first and second parts 21a, 21b of the torque support 21 relative to each other.

[0131] Thus, only the first part 21a of the torque support 21 is arranged inside the casing 17 of the electromechanical actuator 11, following the fitting of the torque support 21 inside the casing 17, up to the stop 33, in the assembled configuration of the electromechanical actuator 11.

[0132] Here, the stop 33 of the torque support 21 is produced in the form of a shoulder and, more particularly, in the form of a collar, in particular of cylindrical shape and with a rectilinear generatrix.

[0133] Advantageously, the electronic control unit 15 can be arranged at least partly inside the casing 17 of the electromechanical actuator 11.

[0134] Furthermore, the electronic control unit 15 may be arranged at least partly outside the casing 17 of the electromechanical actuator 11 and, in particular, mounted on one of the two supports 23, on one of the cheeks 10 of the box 9 or in the torque support 21.

[0135] Here, the first electronic card 15a of the electronic control unit 15 is arranged inside the casing 17 of the electromechanical actuator 11. Furthermore, the second electronic card 15b is arranged inside the torque support 21 of the electromechanical actuator 11.

[0136] Here and as illustrated in [Fig.3], the torque support 21 comprises a cover 22. Furthermore, the second electronic card 15b is arranged inside a housing formed between the second part 21b of the torque support 21 and the cover 22.

[0137] Advantageously, the torque support 21 comprises at least one button and a power connector, for example a connector according to the USB standard, from the English “Universal Serial Bus”, preferably a USB Type-C connector, not shown, which allows the connection of the electromechanical actuator 11 to an external electrical power supply source.

[0138] This or these buttons can make it possible to adjust the electromechanical actuator 11 through one or more configuration modes, to pair one or more control units 12, 13 with the electromechanical actuator 11, to reset one or more parameters, which may be, for example, an end-of-travel position, to reset the paired control unit(s) 12, 13 or even to control the movement of the screen 2.

[0139] Here, the torque support 21 comprises a single button.

[0140] The number of buttons of the torque support is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0141] Advantageously, the torque support 21 comprises at least one display device, not shown, so as to allow a visual indication, which may be, for example, a state of charge of the main battery 24.

[0142] Advantageously, the display device comprises at least one lighting source, not shown, in particular a light-emitting diode, mounted on the second electronic card 15b and, optionally, a transparent or translucent cover and / or a light guide, to allow the passage of the light emitted by the lighting source.

[0143] Here, the torque support 21 comprises a single display device.

[0144] The number of display devices is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0145] Advantageously, the output shaft 20 of the electromechanical actuator 11 is arranged inside the winding tube 4 and at least partly outside the casing 17 of the electromechanical actuator 11.

[0146] Here, one end of the output shaft 20 projects relative to the casing 17 of the electromechanical actuator 11, in particular relative to a second end 17b of the casing 17 opposite the first end 17a.

[0147] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive in rotation a connecting element, not shown, connected to the winding tube 4. The connecting element is produced in the form of a wheel.

[0148] When the electromechanical actuator 11 is put into operation, the electric motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11 drives the winding tube 4 in rotation via the connecting element.

[0149] Thus, the winding tube 4 rotates the screen 2 of the occulting device 3, so as to open or close the opening 1.

[0150] The electrical power supply device 31 and the electrical connections in the occulting device 3 are now described with reference to FIGS. 4 to 6.

[0151] The electrical power supply device 31 comprises a first electrical connection element 44 and a second electrical connection element 46.

[0152] The first electrical connection element 44 is arranged at the level of the load bar 8 of the concealment device 3. By “at the level of the load bar”, it is meant that the first electrical connection element 44 is integral with the load bar 8. In the example, the first electrical connection element 44 is integrated into the second end 8b of the load bar 8.

[0153] The first electrical connection element 44 is electrically connected to the charging connector 40. Thus, the first electrical connection element 44 is configured to be electrically connected, in other words is electrically connected, to the external electrical power supply source 42 via the charging connector 40, when the external electrical power supply source 42 is occa- sionally connected to the charging connector 40.

[0154] The second electrical connection element 46 is arranged at the level of the holding device 9, 23 of the screen 2. By “at the level of the holding device”, it is meant that the second electrical connection element 46 is integral with the holding device 9, 23, in particular with the box 9, with one of the cheeks 10 or with one of the supports 23, or with the torque support 21. In the example, the second electrical connection element 46 is fixed to one of the two supports 23 by means of a fixing lug 23a.

[0155] The second electrical connection element 46 is electrically connected to the main battery 24, for example via an electrical cable (not shown) extending from the second electrical connection element 46 to the main battery 24 via the power connector of the torque support 21, at the first end 17a of the casing 17. The electrical cable may comprise one or more cable portions and one or more electrical connectors.

[0156] The second electrical connection element 46 is configured to cooperate, in other words cooperates, with the first electrical connection element 44 so as to establish an electrical connection between the first electrical connection element 44 and the second electrical connection element 46, consequently between the external electrical power supply source 42 and the main battery 24. This cooperation can only take place when the screen 2 is placed in the retracted configuration and the first and second electrical connection elements are facing each other. A connection position of the charging bar 8 is defined as a position in which an electrical connection is established between the first electrical connection element 44 and the second electrical connection element 46.

[0157] Thus, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is implemented only when the first electrical connection element 44 is arranged close to the second electrical connection element 46, in particular when the first electrical connection element 44 is in direct contact with the second electrical connection element 46, so as to be able to recharge the main battery 24 from the external electrical power supply source 42.

[0158] In this way, the electrical connection between the main battery 24 and the external electrical power supply source 42 implemented by the first electrical connection element 44 and the second electrical connection element 46 is reliable, allows efficient energy transfer and minimizes the costs of obtaining the occulting device 3 by simple realization.

[0159] In the example, when screen 2 is in the retracted configuration and the bar load 8 is in the connection position, the first electrical connection element 44 and the second electrical connection element 46 are aligned, that is to say are opposite each other, along an axis Y perpendicular to the axis of movement Z and perpendicular to the axis of rotation X.

[0160] Preferably, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is made using electrical contacts. In a variant of the invention not shown, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is made by induction.

[0161] In the example, this electrical connection is made using electrical contacts. For this purpose, the second electrical connection element 46 comprises electrical contacts, not shown, which are Pogo pin type pins, or spring pins, i.e. pins composed of a pin sliding in a cylinder, the pin being constrained relative to the cylinder by an internal spring. In other words, each electrical contact comprises a retractable pin subjected to the action of a spring. Alternatively, the second electrical connection element 46 comprises electrical contacts of a type other than Pogo pin type pins.

[0162] In the example, the first electrical connection element 44 comprises two electrical contacts 50, which are metal plates extending perpendicular to the electrical contacts of the second electrical connection element 46. Advantageously, the electrical contacts 50 are made with a ferromagnetic material.

[0163] When the screen 2 is in the retracted configuration, the electrical contacts of the second electrical connection element 46 are in contact with the electrical contacts 50 of the first electrical connection element 44, thus ensuring an electrical connection between the first and second electrical connection elements.

[0164] In the example, the electrical power supply device 31 operates in direct current. Thus, a direct current flows between the first electrical connection element 44 and the second electrical connection element 46. In practice, the second electrical connection element 46 comprises two groups of electrical contacts, or two electrical contacts, one of which forms a positive terminal and the other forms a negative terminal. Furthermore, a first electrical contact 50 of the first electrical connection element 44 forms a positive terminal and the second electrical contact 50 of the first electrical connection element 44 forms a negative terminal.

[0165] Advantageously, the first electrical connection element 44 and the second electrical connection element 46 further comprise auxiliary electrical contacts, or groups of auxiliary electrical contacts, intended to cooperate together when the screen 2 is in the retracted configuration and allowing communication data to be transferred between the first electrical connection element 44 and the second electrical connection element 46.

[0166] Advantageously, the electrical energy supply device 31 further comprises a photovoltaic solar panel 52, integrated or fixed to the charging bar 8, i.e. integral with the charging bar. The photovoltaic solar panel 52 is oriented towards the opening 1 so as to be exposed to solar radiation, in particular when the screen 2 is in the deployed configuration.

[0167] Advantageously, the electrical energy supply device 31 further comprises a secondary battery 54, integrated or fixed to the charging bar 8, i.e. integral with the charging bar. In [Fig. 4], the charging bar 8 is partially masked to make the secondary battery 54 visible.

[0168] The secondary battery 54 is electrically connected to the photovoltaic solar panel 52. Thus, the electrical energy generated by the photovoltaic solar panel 52 when it is exposed to solar radiation is stored by the secondary battery 54. In other words, the photovoltaic solar panel 52 makes it possible to recharge the secondary battery 54.

[0169] The secondary battery 54 is electrically connected to the first electrical connection element 44.

[0170] Thus, when the screen 2 is in the retracted configuration, the secondary battery 54 is electrically connected to the main battery 24 via the first electrical connection element 44 and the second electrical connection element 46.

[0171] The secondary battery 54 then makes it possible to store the electrical energy generated by the photovoltaic solar panel 52 when the screen 2 is in the deployed configuration and then to transfer this electrical energy to the main battery 24 when the screen 2 is in the retracted configuration.

[0172] In the example, the photovoltaic solar panel 52 is configured to produce, in other words produces, a direct current and the secondary battery 54 is configured to deliver, in other words delivers, a direct current to the first electrical connection element 44.

[0173] In practice, the secondary battery 54 has a lower electrical energy storage capacity than the main battery 24, for example corresponding to approximately 25% of the electrical energy storage capacity of the main battery 24. In other words, a maximum quantity of electrical energy that can be stored by the main battery 24 is greater than at least 4 times a maximum quantity of electrical energy that can be stored by the secondary battery 54.

[0174] Thus, the main battery 24 is rechargeable either from the external electrical power supply source 42, or from the photo solar panel photovoltaic solar panel 52 via the secondary battery 54. The photovoltaic solar panel 52 thus forms an internal electrical energy supply source for the occultation device 3. In other words, the external electrical energy supply source 42 and the photovoltaic solar panel 52 are two separate electrical energy supply sources for recharging the main battery 24.

[0175] Advantageously, the electrical energy supply device 31 comprises a charging connector 40, arranged at the level of the charging bar 8. The charging connector 40 is for example a connector according to the USB standard, from the English “Universal Serial Bus”, preferably a USB Type-C connector.

[0176] The charging connector 40 is configured to be electrically connected, in other words is electrically connected, to an external electrical power supply source 42 configured to provide the electrical power supply device 31 with electrical energy.

[0177] Advantageously, the external electrical power supply source 42 is a charger-converter that can be plugged into a wall electrical outlet, so as to provide a direct current power supply to the electrical power supply device 31 from an alternating current mains power supply network.

[0178] Advantageously, the external electrical power supply source 42 is connected to the charging connector 40 using a corresponding connector 43' at the end of an electrical power supply cable 43.

[0179] Advantageously, the secondary battery 54 is also connected to the recharging connector 40, so as to allow the recharging of the secondary battery 54 from the external electrical power supply source 42. Thus, the secondary battery 54 is preferentially recharged by the photovoltaic solar panel 52, but can also be recharged from the external electrical power supply source 42, for example when the photovoltaic solar panel 52 is faulty or in a variant in which the occulting device 3 does not have a photovoltaic solar panel.

[0180] To ensure a reliable electrical connection between the first electrical connection element 44 and the second electrical connection element 46, and therefore between the main battery 24 and its two electrical energy supply sources 42, 52, the concealment device 3 further comprises a hooking device 60, visible in FIGS. 4 and 5.

[0181] The hooking device 60 is arranged at the level of the holding device 9, 23 of the screen 2 and makes it possible to exert a force F on the load bar 8 when the screen is in the retracted configuration. The force F is exerted in a hooking direction DA comprising at least one component along the Y axis perpendicular to the detent axis placement Z and perpendicular to the axis of rotation X. By "at the level of the holding device", it is meant that the attachment device 60 is integral with the holding device 9, 23, in particular the box 9, one of the cheeks 10 or one of the supports 23, or the torque support 21.

[0182] In the example, the force F is exerted along an axis Y which is perpendicular to the movement axis Z and to the rotation axis X, that is to say perpendicular to the screen 2. In other words, in the example, the hooking direction DA is parallel to the axis Y

[0183] The force F tends to bring the load bar 8 closer to the holding device 9, 23, along the hooking direction DA, to ensure cooperation between the first electrical connection element 44 and the second electrical connection element 46. In practice, the force F tends to press the electrical contacts 50 of the first electrical connection element 44 against the electrical contacts of the second electrical connection element 46, that is to say it tends to put the first electrical connection element 44 in abutment, or in contact, against the second electrical connection element 46.

[0184] The load bar 8 is thus in the connection position when, under the effect of the force F generated by the attachment device 60, the load bar is pressed against, that is to say in mechanical contact with, the holding device 9, 23.

[0185] In a particularly advantageous manner, the electrical contacts of the second electrical connection element 46 extend parallel to the hooking direction DA and the electrical contacts 50 of the first electrical connection element 44, formed by metal plates, extend substantially perpendicular to the hooking direction DA, making it possible to optimize their contact with the electrical contacts 50 of the first electrical connection element 44, in particular when the electrical contacts of the second electrical connection element 46 are spring pins. Thus, the force F exerted by the hooking device 60 on the load bar 8 is exerted parallel to the force exerted by the spring of a spring pin against the pin of this spring pin.The insertion of the pins of each spring pin by pressing the second electrical connection element 46 against the first electrical connection element 44 is then facilitated because the compression of the spring of each spring pin, under the effect of the force F, is facilitated, and makes it possible to obtain good electrical contact between the spring pins and the metal plates 50.

[0186] In the example, the attachment device 60 comprises a magnet (not shown), more precisely a permanent magnet, which is arranged at the level of the holding device 9, 23, and more precisely at the level of the second electrical connection element 46.

[0187] The force F exerted by the attachment device 60 on the load bar 8 when the screen 2 is in the retracted configuration corresponds to an attractive force exerted by the magnet on the electrical contacts 50 of the first electrical connection element 44.

[0188] In practice, the magnet is oriented so that the magnetic field generated by the magnet is maximum along the direction of attachment DA.

[0189] As best seen in [Fig.5], the first electrical connection element 44 and the second electrical connection element 46 are opposite each other along the hooking direction DA and are approximately at the same height along the movement axis Z when the screen 2 is in the retracted configuration. The force F exerted by the magnet on the first electrical connection element 44 is thus maximized.

[0190] Preferably, the second electrical connection element 46 is located, parallel to the attachment direction DA, between the first electrical connection element 44 and the opening 1 when the screen 2 is in the retracted configuration.

[0191] Thanks to the positioning of the magnet of the attachment device 60, the force F is exerted on the first connection element 46 only when the screen 2 is in the retracted configuration. Indeed, when the screen 2 is in the deployed configuration, the first connection element 46 is distant from the magnet, along the movement axis Z, so that the magnet does not exert any force on the first connection element 46. Thus, when the screen 2 is in the deployed configuration, the position of the load bar 8 is not affected by the attachment device 60.

[0192] In practice, during a rise of the screen 2 from its deployed configuration to its retracted configuration, the first connection element 46 enters the magnetic field of the magnet when the screen 2 approaches its retracted configuration, for example when the load bar 8 is located less than 5 centimeters from the magnet, along the displacement axis Z.

[0193] Thus, during the end of the raising of the screen 2 from its deployed configuration to its retracted configuration, corresponding for example to the movement of the screen over the last 5 centimeters, the end 8a of the load bar 8 moves in a direction corresponding to the movement axis Z and punctually under the effect of the attraction of the magnet, according to the attachment direction DA: this movement therefore comprises a component carried by the movement axis Z, due to the traction generated by the electromechanical actuator 11 on the screen 2, and a component carried by the attachment direction DA, due to the force F generated by the magnet. According to the attachment direction DA, the load bar 8 thus moves towards the holding device 9, 23 until it comes into mechanical contact with the holding device 9, 23, that is to say until it reaches its connection position.In the example, the load bar 8 moves in the hooking direction DA until the first electrical connection element 44 comes into abutment against the second electrical connection element 46.

[0194] The attachment device 60 is configured to compensate, in other words compensates, for an offset between the first electrical connection element 44 and the second electrical connection element 46, parallel to the hooking direction DA, that is to say perpendicular to the screen 2, when the screen 2 reaches its retracted configuration. Thus, when the screen 2 reaches the retracted configuration, the hooking device 60 makes it possible to ensure the electrical connection between the first electrical connection element 44 and the second electrical connection element 46.

[0195] The construction of the occulting device 3, and more precisely of the electrical power supply device 31 and of the attachment device 60, makes it possible to reach the second electrical connection element 46 arranged at the level of the holding device 9, 23 of the screen 2 by the first electrical connection element 44, following a movement of the screen 2 to the retracted configuration, while compensating for any offset of the first electrical connection element 44 relative to the second electrical connection element 46 perpendicular to the screen 2 by means of the attractive force of the magnet.

[0196] Consequently, the construction of the concealment device 3 makes it possible to guarantee simplified and ergonomic recharging of electrical energy for the user of the main battery 24 from the secondary battery 54 or from the external electrical energy supply source 42.

[0197] Furthermore, the construction of the concealment device makes it possible to avoid a user having to climb a stepladder to access the second electrical connection element 46 arranged at the level of the holding device 9, 23 of the screen 2 when the main battery 24 is recharged from the external electrical power supply source 42.

[0198] Indeed, the electrical power supply cable 43 electrically connecting the external electrical power supply source 42 to the charging connector 40 is driven by the movement of the screen 2, by means of the electromechanical actuator 11, until the retracted configuration of the screen 2.

[0199] Furthermore, the electrical connection of the external electrical power supply source 42 to the first electrical connection element 44 to the charging connector 40 is facilitated, since this electrical connection can be implemented by simple electrical contact when the screen 2 is in a deployed configuration or in a low end-of-travel position, in other words without having to climb onto a stepladder to access the charging connector 40 or without insertion effort between male and female type parts at the level of the holding device 9, 23.

[0200] In addition, the main battery 24 can be recharged without having to dismantle a part of the occulting device 3 and, in particular, of the holding device 9, 23 of the screen 2, in particular of the box 9 of the occulting device 3.

[0201] Advantageously, the retracted configuration of the screen 2, as well as the position height of the screen, can be determined when installing the blackout device 3.

[0202] In an exemplary embodiment, the retracted configuration can be determined as reached by means of a counting device, notably identifying the number of revolutions traveled and the angle of rotation of the output shaft 20 of the electromechanical actuator 11, the number of revolutions traveled and the angle of rotation of the rotor of the electric motor 16 or even the operating time of the electromechanical actuator 11.

[0203] Alternatively, the retracted configuration of the screen 2 may be determined as reached by means of the stop and / or obstacle detection device of the electromechanical actuator 11.

[0204] For example, the retracted configuration of the screen 2 is defined by the mechanical contact of the load bar 8 against the holding device 9, 23.

[0205] Advantageously, the retracted configuration of the screen 2 is determined to be reached when the electrical connectors 50 of the first electrical connection element 44 are electrically connected to the electrical connectors of the second electrical connection element 46, so as to send a signal to the electronic control unit 15.

[0206] Thus, following receipt of this signal by the electronic control unit 15, the latter issues a command to stop the electromechanical actuator 11.

[0207] In the different variants, the movement of the first electrical connection element 44 relative to the second electrical connection element 46 is controlled by the electronic control unit 15 and, more particularly, by the movement of the screen 2 through the electromechanical actuator 11.

[0208] In a variant of the invention not shown, the occultation device 3 does not comprise a photovoltaic panel 52.

[0209] In a variant of the invention not shown, the concealment device 3 does not include a charging connector 40.

[0210] In a variant of the invention not shown, the photovoltaic solar panel 52 is not integrated or fixed to the load bar 8 but is fixed to the screen 2, for example at the second end 2c of the screen.

[0211] The electrical power supply device 31 will now be described in more detail with reference to [Fig. 6]. In [Fig. 6], the load bar 8 is illustrated schematically using a rectangle in long dotted lines, the elements of the electrical power supply device 31 which are integrated into the load bar being arranged inside this rectangle in long dotted lines.

[0212] Advantageously, the electrical energy supply device 31 comprises a remote electronic control unit 64, which is integrated into the load bar 8. The remote electronic control unit 64 makes it possible to control the elements of the electrical energy supply device 31 arranged in or on the charging bar, such as for example the photovoltaic solar panel 52 and the battery 54. For example, the remote electronic control unit 64 comprises a management unit for the secondary battery 54, making it possible in particular to measure the state of charge of the secondary battery 54, for example by measuring its no-load voltage or by coulombmetry.

[0213] Furthermore, the remote electronic control unit 64 advantageously makes it possible to detect the connection of the external electrical power supply source 42 to the charging connector 40, for example by detecting an electrical voltage delivered by the external electrical power supply source to the charging connector.

[0214] Preferably, the remote electronic control unit 64 also comprises an electronic card equipped with an accelerometer, allowing the detection of an obstacle impacting the load bar 8 during the movement of the screen 2 and / or the detection of an end-of-travel position of the screen 2, for example contact of the load bar 8 with the threshold 7 of the opening 1.

[0215] The remote electronic control unit 64 comprises a communication device making it possible to communicate with the first electronic card 15a and / or with the second electronic card 15b, that is to say making it possible to communicate with the electronic control unit 15. This communication makes it possible, in particular, to inform the electronic control unit 15 of a charge level of the secondary battery 54, of a state of the photovoltaic solar panel, of the connection of the external energy supply device 42 to the charging connector 40, or even of the detection of an obstacle or of an end-of-travel position to cause the operation of the electromechanical actuator 11 to stop.

[0216] Advantageously, this communication device and the electronic control unit 15 each comprise a transmitter and a receiver, allowing the bidirectional exchange of information between the remote electronic control unit 64 and the electronic control unit 15.

[0217] As seen in [Fig. 6], the charging connector 40 is connected to the first electrical connection element 44 via a conductive element 70 and a conductive element 70'. Each conductive element 70, 70' is, for example, an electrical cable or an electrical track formed on a printed circuit board. The conductive elements 70 and 70' are suitable for transmitting a direct current: in the example, the conductive element 70 corresponds to a positive pole and the conductive element 70' corresponds to a negative pole. Thanks to the conductive elements 70 and 70' suitable for transmitting a direct current, the external electrical power supply source 42 is directly connected to the first connection element electric 44 and thus to the main battery 24 when the screen 2 is in the retracted configuration, thus allowing the main battery 24 to be recharged directly from the external electrical power supply source 42.

[0218] Generally speaking, in [Fig.6], only the positive pole of the conductive elements connecting the different components of the charging bar 8 is shown: for the clarity of [Fig.6], the negative pole of these conductive elements is not shown, with the exception of the conductive element 70' which is shown, between the charging connector 40 and the first electrical connection element 44.

[0219] Advantageously, the secondary battery 54 is also connected to the first electrical connection element 44, in parallel with the charging connector 40. Thus, the secondary battery 54 and the external electrical power supply source 42 are two potential energy sources which can supply the main battery 24 in turn. In particular, the secondary battery 54 is connected to the conductive element 70 or to the first connection element 44 by a conductive element 71. In practice, the conductive element 71 comprises two electrical cables or two electrical tracks formed on a printed circuit board and is thus suitable for transmitting a direct current. For the clarity of [Fig. 6], only a positive pole of the conductive element 71 is shown.

[0220] Advantageously, the secondary battery 54 is also connected to the charging connector 40. Thus, the external electrical power supply source 42 can be connected to the secondary battery 54 and can recharge the latter.

[0221] Advantageously, the electrical energy supply device 31 comprises a diode 72, connected to the conductive element 71, which allows the flow of current from the photovoltaic solar panel 52 to the secondary battery 54 and which prevents the flow of current from the secondary battery 54 to the photovoltaic solar panel. The diode 72 thus makes it possible to protect the photovoltaic solar panel from currents coming from the secondary battery 54, or even from the external electrical energy supply source 42 or from the main battery 24, which are likely to damage the photovoltaic solar panel. In a variant of the invention not shown, the diode 72 is integrated into the photovoltaic solar panel.

[0222] Advantageously, the electrical energy supply device 31 comprises a diode 74, mounted on the conductive element 70, which allows the flow of current from the charging connector 40 to the secondary battery 54 and to the first electrical connection element 44, and which prevents the flow of current from the secondary battery 54 or from the first electrical connection element 44 to the charging connector 40. The diode 74 thus makes it possible to protect the external electrical energy supply source 42 from currents coming from the secondary battery 54 or from the main battery 24, which are likely to damage the external electrical power supply source 42. In a variant of the invention not shown, the diode 74 is integrated into the external electrical power supply source and thus does not belong to the electrical power supply device 31.

[0223] Advantageously, the electrical power supply device 31 comprises a diode 76, mounted on the conductive element 71, which allows the flow of current from the secondary battery 54 to the first electrical connection element 44, and which prevents the flow of current from the charging connector 40 and the first electrical connection element 44 to the secondary battery 54. The diode 76 thus makes it possible to prevent the flow of current from the main battery 24, to avoid a possible discharge of the main battery to the secondary battery in the retracted configuration. The diode 76 also has the purpose of blocking the flow of current from the external electrical power supply source 42 to the secondary battery 54.Thus, the diode 76 makes it possible to prevent the recharging current supplied by the external electrical power supply source 42 from recharging the secondary battery 54, so as to promote the recharging of the main battery 24, thus making it possible to accelerate the recharging of the main battery and to optimize the transfer of energy to the main battery 24.

[0224] Advantageously, the electrical energy supply device 31 comprises a switching member 77, which in the example is a controlled switch. The switching member 77 is installed in parallel with the diode 76 and is controllable between a closed state, in which the switching member 77 electrically connects the charging connector 40 to the secondary battery 54 to allow a flow of electric current from the charging connector to the secondary battery, and an open state, in which the switching member electrically isolates the charging connector from the secondary battery, to prevent a flow of electric current from the charging connector to the secondary battery. In other words, when the switching member 77 is in the closed state, it allows the diode 76 to be short-circuited.

[0225] The switching member 77 is advantageously controlled by the remote electronic control unit 64. In [Fig. 6], the remote electronic control unit 64 is shown connected by short dotted lines to the switching member 77 to illustrate the connection allowing the remote electronic control unit to control the switching member. This connection is, for example, established using an electrical cable or an electrical track formed on a printed circuit board. Preferably, the switching member is a normally open switch. Thus, in the absence of specific control of the switching member 77 by the remote electronic control unit 64, any current supplied by the external electrical power supply source can be transferred to the battery main 24, when the latter is connected to the charging connector 40, in particular when the screen 2 is in the retracted configuration.

[0226] Preferably, the remote electronic control unit 64 controls the switching member 77 so that the switching member is in the closed state when the screen 2 is in the retracted configuration and when the external electrical power supply source 42 is connected to the charging connector 40 and when the main battery is considered charged up to a threshold charge level, thus allowing current to flow from the external electrical power supply source 42 to the secondary battery 54 when the main battery 24 is no longer capable of being recharged by the external electrical power supply source 42.Thus, the switching member 77 controlled in this way by the remote electronic control unit 64 is particularly advantageous because it allows the secondary battery 54 to be recharged using the external electrical power supply source 42 only at the end of recharging of the main battery 24. Thus, the recharging of the secondary battery 54 takes place only after the recharging of the main battery 24.

[0227] Advantageously, the electrical energy supply device 31 also comprises a diode 78, mounted on the conductive element 70 between the switching member 77 and the first electrical connection element 44. The diode 78 prevents the flow of current from the first electrical connection element 44 to the secondary battery 54 via the switching member 77. Thus, when the switching member 77 is in the closed state and the screen is in the retracted configuration, the diode 78 prevents a flow of current from the main battery 24 to the secondary battery 54, thus avoiding any discharge of the main battery 24.

[0228] In a variant of the invention that is not shown, the electrical power supply device 31 does not include the diode 78 and the switching member 77 is controlled in the closed state by the remote electronic control unit 64 only when the screen is in the deployed configuration. In other words, the switching member 77 is configured to be in the open state when the screen is in the retracted configuration, thus making it possible to avoid any flow of current from the main battery 24 to the secondary battery 54, while allowing the secondary battery 54 to be recharged from the external electrical power supply source 42 when the screen is in the deployed configuration.

[0229] Recharging the secondary battery 54 by the external electrical power supply source 42 is not considered a priority, due to the low capacity of the latter compared to that of the main battery 24 and due to the energy efficiency losses if the energy passes through the secondary battery 54. However, this recharging may still be possible.

[0230] The conductive elements 70, 70', 71, the diodes 74, 76, 78 and the switching member 77 together form electronic means electrically connecting the secondary battery 54 to the first electrical connection element 44 and to the charging connector 40.

[0231] Preferably, the diodes 72, 74, 76 and 78 are low threshold Schottky diodes.

[0232] An example of a method for controlling the occultation device 3 of the first embodiment is now described, aimed at enabling the main battery 24 to be recharged from the external electrical power supply source 42.

[0233] This control method begins with the connection of the external electrical power supply source 42 to the charging connector 40. This connection is made by a user of the concealment device 3 and when the screen 2 is in the deployed configuration. Thus, this connection is simple to implement, because the charging bar 8 is more accessible than when the screen 2 is in the retracted configuration, which in particular avoids the use of a stepladder to access the charging connector 40.

[0234] The connection of the external electrical power supply source 42 to the charging connector 40 is detected by the remote electronic control unit 64, which transmits this information to the electronic control unit 15. After receiving this information, the electronic control unit 15 controls the electromechanical actuator 11 to drive the screen 2 from its deployed configuration to its retracted configuration, so as to establish an electrical connection between the external electrical power supply source 42 and the main battery 24 via the first electrical connection element 44 and the second electrical connection element 46.

[0235] During this ascent, the electrical power supply cable 43, the connector 43' of which is connected to the charging connector 40, is raised by the movement of the charging bar 8. In other words, the raising of the screen 2 towards its retracted configuration causes the movement of the electrical power supply cable 43.

[0236] Optionally, before the establishment of the electrical connection between the main battery 24 and the external electrical power supply source 42, that is to say before the arrival of the screen 2 in the retracted configuration, the remote electronic control unit 64 controls the switching member 77 so that the switching member is in the closed configuration, so as to allow the recharging of the secondary battery 54 from the external electrical power supply source 42. Thus, the external electrical power supply source 42 is used to recharge the secondary battery 54 during the movement of the screen 2 to its retracted configuration, before the recharging of the main battery 24, or even before the movement of the screen 2 to its retracted configuration.

[0237] Once the electrical connection is established between the main battery 24 and the external electrical power source 42, the main battery is recharged using the external electrical power source.

[0238] In practice, when the screen 2 is in the retracted configuration, that is to say when the first electrical connection element 44 cooperates with the second electrical connection element 46, the switching member 77 is preferably in the open configuration, to prevent recharging of the secondary battery 54 from the external electrical power supply source 42. In other words, when the recharging connector 40 is electrically connected to the external electrical power supply source 42 and when the electrical connection is established between the main battery 24 and the external electrical power supply source 42, only the main battery is recharged using the external electrical power supply source.

[0239] Advantageously, when the electronic control unit 15 detects that the recharging of the main battery 24 is complete, then the remote electronic control unit 64 controls the switching member 77 in the closed configuration, so as to allow the recharging of the secondary battery 54 from the external electrical power supply source 42, even if the screen 2 is in the retracted configuration.

[0240] Preferably, once the main battery 24 is fully recharged, the electronic control unit 15 controls the electromechanical actuator 11 to drive the screen 2 from its retracted configuration to its original deployed configuration. Thus, after recharging the main battery, the charging bar 8 returns to its original position and a user of the concealing device 3 can easily access the charging connector 40 to disconnect the electrical power supply source 42 from the charging connector 40.

[0241] Advantageously, during the movement of the screen 2 from its retracted configuration to its original deployed configuration, that is to say after the electrical connection between the main battery 24 and the external electrical power supply source 42 has been broken, the remote electronic control unit 64 controls the switching member 77 so that the switching member is in the closed configuration, so as to allow the recharging of the secondary battery 54 from the external electrical power supply source 42. Thus, the external electrical power supply source 42 is used to recharge the secondary battery 54 during the movement of the screen 2 from the retracted configuration, after the recharging of the main battery 24.

[0242] Advantageously, the first electrical connection element 44 and the second electrical connection element 46 comprise auxiliary electrical contacts, or groups of auxiliary electrical contacts, intended to cooperate together when the screen 2 is in the retracted configuration and allowing communication data to be transferred between the first electrical connection element 44 and the second electrical connection element 46. In addition, the charging connector 40 comprises auxiliary connection elements configured to cooperate with the connector 43' of the electrical power supply cable 43 to exchange data with the external electrical power supply source 42.These auxiliary connection elements of the charging connector 40 as well as these auxiliary electrical contacts of the electrical connection elements 44, 46 are connected to the electronic control unit 15 and / or to the remote electronic control unit 64 and allow the exchange of data between the external electrical energy supply source 42, the secondary battery 54, the main battery 24 and the electronic control unit 15 and / or the remote electronic control unit 64.

[0243] Advantageously, to enable the transmission of communication data between the charging connector 40 and the first electrical connection element 44, the electrical energy supply device 31 comprises an auxiliary conductive element 79 which connects the charging connector and the first electrical connection element 44. The auxiliary conductive element 79 is represented by short dotted lines in [Fig. 6]. In other words, the auxiliary conductive element 79 connects the auxiliary connection elements of the charging connector 40 to the auxiliary electrical contacts, or groups of auxiliary electrical contacts, of the first connection element 44.

[0244] This data exchange is preferably carried out using the USB Power Delivery standard and further makes it possible to control the electrical power supply source 42 to adapt the electrical power delivered by the electrical power supply source to the electrical power acceptable for the main battery 24.

[0245] This data also makes it possible to control a so-called fast charging profile of the main battery 24 and / or the secondary battery 54 from the external electrical power supply source 42. In particular, when the charging connector 40 is a USB Type-C connector, its auxiliary connection elements correspond to the configuration channels of the USB Type-C connector.

[0246] The fast charging profile of the main battery can thus comprise a greater power, supplied by the external electrical power supply source 42 than for a conventional charging profile without prior communication or so-called slow charging, for which the power transmitted by the external electrical power supply source 42 is limited.

[0247] Advantageously, the electrical energy supply source 42 is controlled by the charging circuit of the electromechanical actuator 11. In other words, the profile of charging of the main battery 24 is defined by the charging circuit. Thus, the electrical energy supply source 42 adapts to the optimum charging profile of the main battery 24.

[0248] In a variant not shown of the first embodiment, the electrical energy supply device 31 of the occultation device 3 does not comprise electronic means electrically connecting the secondary battery 54 to the recharging connector 40 and allowing the recharging of the secondary battery 54 from the external energy supply source 42. In other words, the electrical energy supply device 31 does not comprise the switching member 77. In such a variant, the secondary battery 54 is recharged solely using the photovoltaic solar panel 52.

[0249] We will now describe, with reference to [Fig.7], a concealment device 3 according to a second embodiment of the invention, and more precisely its electrical energy supply device 31'.

[0250] In the second embodiment, elements similar to those of the first embodiment bear the same references and operate in the same way. In the following, the differences between the first and second embodiments are mainly described.

[0251] Furthermore, if a component is mentioned in the description of the second embodiment without being shown in [Fig.7], it corresponds to the same element shown in Figures 1 to 6 for the first embodiment.

[0252] As in the first embodiment, the electrical energy supply device 31' comprises a conductive element 70 electrically connecting the charging connector 40 to the first electrical connection element 44.

[0253] One of the main differences of the second embodiment with the first embodiment is that the electrical energy supply device 31' comprises electronic means different from the diode 76 and the switching device 77 of the first embodiment for electrically connecting the secondary battery 54 to the first electrical connection element 44 and to the charging connector 40.

[0254] Here, the electrical power supply device 31' comprises in particular two insulated gate field effect transistors, more generally designated by their English name "Metal-Oxide-Semiconductor Field-Effect Transistor" or by the corresponding acronym "MOSFET". In the remainder of the description, the insulated gate field effect transistors are designated as MOSFETs.

[0255] In a manner known per se, each MOSFET comprises an electrode called a gate, designated by the letter G in [Fig.7], a source designated by the letter S in [Fig.7] and a drain designated by the letter D in [Fig.7].

[0256] In practice, the electrical energy supply device 31' comprises a assembly of a first MOSFET 80 and a second MOSFET 84, mounted in series with the first MOSFET 80, the assembly of MOSFETs 80, 84 thus connecting the secondary battery 54 to the charging connector 40 and to the first electrical connection element 44. Each of the MOSFETs 80, 84 comprises an intrinsic diode 82, 86. The two MOSFETs are mounted head to tail, that is to say that the sources of the two MOSFETs 80, 84 are directly connected to each other.

[0257] The MOSFET assembly 80, 84 is connected to the conductive element 70 upstream of the diode 74.

[0258] Furthermore, the set of MOSFETs is connected to a divider bridge comprising a resistor 88 connected between the gate of the two MOSFETs 80, 84 and the conductive element 70 and a resistor 90 connected between the conductive element 70 and the conductive element 70'.

[0259] This assembly makes it possible to passively block the conduction of the MOSFETs when the external electrical power supply source 42 is connected to the charging connector 40, by imposing the voltage of the external electrical power supply source 42 on the input of the set of MOSFETs. The secondary battery cannot then discharge to the main battery 24. When the charger is not connected, the set of MOSFETs is said to be in conduction and a threshold voltage (~0V) is imposed at the input of the set. The secondary battery can then discharge to the main battery 24 to allow the main battery 24 to be recharged.

[0260] In other words, the set of MOSFETs 80, 84 acts as a switching member controlled as a function of the voltage at the terminals of the charging connector 40, the set of MOSFETs allowing the flow of a current from the secondary battery 54 to the first electrical connection element 44 only when the voltage at the terminals of the charging connector is lower than a predetermined threshold, for example equal to 1.5 V. In other words, the set of MOSFETs is in a closed state, or on state, or on configuration, when the voltage at the terminals of the charging connector is lower than the predetermined threshold and is in an open state, or off state, or off configuration, when this voltage is higher than the predetermined threshold.Furthermore, the set of MOSFETs acts as a diode preventing the flow of a current from the charging connector 40 or from the first electrical connection element 44 to the secondary battery 54, thanks to the arrangement of the two MOSFETs mounted in series and head to tail.

[0261] Thus, the set of MOSFETs 80, 84 represents an alternative to the switching member 77 and the diode 76 of the first embodiment, which has the advantage of not requiring control by the remote electronic control unit 64, since the switching of the set of MOSFETs between its open and closed states is carried out according to the voltage at the terminals of the charging connector 40.

[0262] Thanks to the set of MOSFETs 80, 84, the distribution of an electric current from the external electrical power supply source 42 to the main battery 24 and to the secondary battery 54, as well as the recharging of the main battery 24 from the secondary battery 54, is passively selected as a function of the connection state of the external electrical power supply source 42, that is to say as a function of the voltage at the terminals of the recharging connector 40, without requiring intervention from the remote electronic control unit 64. The operation of the electrical power supply device 31' is thus more robust and more reliable.

[0263] Advantageously, the electrical energy supply device 31' also comprises a regulating member 92 and a diode 94, which are mounted in parallel with the first and second MOSFETs 80, 84 between the secondary battery 54 on the one hand and the charging connector 40 and the first electrical connection element 44 on the other hand. The regulating member 92 is preferably a voltage regulator and a current limiter.

[0264] The diode 94 is configured to allow current flow from the charging connector 40 and the first electrical connection element 44 to the secondary battery 54 and to prevent current flow in the reverse direction.

[0265] When the external electrical power supply source 42 is connected to the charging connector 40, and therefore the MOSFET assembly is in the open state, the secondary battery cannot discharge to the main battery 24, but it can be charged by the external electrical power supply source 42 through the regulating member 92 and the diode 94.

[0266] Advantageously, the operation of the regulating member 92 is controlled by the remote electronic control unit 64 so that the regulating member 92 only authorizes current flow from the charging connector 40 to the secondary battery 54 when the screen 2 is in the deployed configuration or when the screen is in the retracted configuration and the main battery 24 is fully recharged.

[0267] Advantageously, the regulating member 92 regulates and limits the current flowing to the secondary battery 54. In other words, the regulating member 92 conditions the current delivered by the external electrical power supply source 42 to deliver to the secondary battery 54 a current adapted to the secondary battery. The secondary battery is thus protected by the regulating member.

[0268] The example of the method for controlling the occultation device 3 described in the context of the first embodiment, aimed at enabling the recharging of the main battery 24 from the external electrical power supply source 42, is also applicable to the second embodiment.

[0269] In practice, when implemented in the occultation device of the second embodiment, the control method described above is modified to take into account the electrical energy supply device 31'. In particular, the switching steps authorizing or preventing the flow of a current from the secondary battery 54 to the first electrical connection element 44 are passively performed by the set of MOSFETs and the recharging of the secondary battery 54 from the external electrical energy supply source 42 is controlled by the regulating member 92.

[0270] In a variant not shown of the second embodiment, the electrical energy supply device 31' of the occultation device 3 does not comprise electronic means electrically connecting the secondary battery 54 to the recharging connector 40 and allowing the recharging of the secondary battery 54 from the external energy supply source 42. In other words, the electrical energy supply device 31 does not comprise the regulating member 92 and the diode 94 and the secondary battery 54 is only connected to the conductive element 70 with the set of MOSFETs 80, 84. In such a variant, the secondary battery 54 is recharged solely using the photovoltaic solar panel 52.

[0271] We will now describe, with reference to [Fig.8], a concealment device 3 according to a third embodiment of the invention, and more precisely its electrical energy supply device 31".

[0272] In the third embodiment, elements similar to those of the first and second embodiments have the same references and operate in the same way. In the following, the differences between the third embodiment and the first and second embodiments are mainly described.

[0273] Furthermore, if a component is mentioned in the description of the third embodiment without being shown in [Fig.8], it corresponds to the same element shown in Figures 1 to 6 for the first embodiment or in [Fig.7] for the second embodiment.

[0274] The electrical power supply device 31" of the third embodiment differs from the electrical power supply device 31' of the second embodiment in that the electronic means comprise a charge management circuit 96, integrated into the charging bar 8. Within the charging bar 8, the charging connector 40, the first electrical connection element 44, the photovoltaic solar panel 52, the secondary battery 54, the remote electronic control unit 64 are only connected to the charge management circuit 96. The charge management circuit 96 manages the power distribution between the charging connector 40, the first electrical connection element 44, the photovoltaic solar panel 52, the secondary battery 54, the remote electronic control unit 64 and the charging connector 40. charging unit 40, the first electrical connection element 44, the photovoltaic solar panel 52 and the secondary battery 54. The remote electronic control unit 64 exchanges data with the charge management circuit 96 to configure, or control, the charge management circuit.

[0275] The charge management circuit 96 is, for example, of the PMIC type, from the English “Power Management Integrated Circuit”, that is to say an integrated power management circuit.

[0276] The charge management circuit 96 receives the electrical power delivered by the external electrical power supply source 42 and distributes this electrical power between the regulating member 92 and the first electrical connection element 44. In other words, the charge management circuit 96 distributes the electrical power delivered by the external electrical power supply source between the main battery 24 and the secondary battery 54.

[0277] Thus, thanks to the charge management circuit 96, it is possible to simultaneously recharge the main battery 24 and the secondary battery 54 when the screen is in the retracted configuration, which is particularly advantageous in particular when the external electrical energy supply source 42 is able to deliver sufficient electrical power to simultaneously recharge these two batteries.

[0278] Furthermore, when the external electrical power supply source 42 is not able to deliver sufficient electrical power to simultaneously recharge the main battery 24 and the secondary battery 54, then the charge management circuit 96 prioritizes the recharging of the main battery 24 by distributing the electrical power delivered by the external electrical power supply source to the first electrical connection element 44 as a priority.

[0279] The embodiments and variants envisaged may be combined to generate new embodiments of the invention, without departing from the scope of the invention.
