Description

Title of the invention: Method for controlling a concealment device and associated concealment device

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

[0002] Generally speaking, 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 configuration and at least a second configuration.

[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 EP-A-3 904 630 is already known, which describes a screening device comprising a screen, a screen holding device, a load bar, an electromechanical actuator and an electrical power supply device. A first end of the screen is attached to the screen holding device. A second end of the screen is attached to the load bar. The electromechanical actuator is configured to drive the screen between a first end-of-travel configuration and a second end-of-travel configuration. The electrical power supply device comprises at least one main battery, secured to the holding device and configured to electrically power the electromechanical actuator, and a photovoltaic panel, attached to the load bar, connected to the main battery and configured to recharge the main battery.Document EP-A-3 904 630 describes a control method for optimizing the operation of the photovoltaic panel, by determining a recharging position of the screen, located between the first end-of-travel position and the second end-of-travel position, in which the photovoltaic panel can receive sunlight. The objective is to only perform a movement if sunlight for the photovoltaic panel in the recharging position is guaranteed. The main criterion on which the method is based is the sunlight received by the photovoltaic panel. The method possibly takes into account a state of charge of the battery. This occulting device and this control method are generally satisfactory. However, to avoid situations of complete discharge, it is useful to take precautions and safety margins, in particular on the level of the battery discharge threshold due to the random nature of the sunlight.The process is therefore not completely optimized.

[0005] Another concealing device is known from WO-A-2017 / 036966, also comprising a screen, a screen holding device, a load bar, an electromechanical actuator and an electrical power supply device. The electromechanical actuator is configured to drive the screen between a retracted configuration and a deployed configuration.This occultation device does not include a photovoltaic panel, but its electrical energy supply device includes a main battery, secured to the holding device and configured to electrically power the electromechanical actuator, an external electrical power source, such as an external battery that can be removably attached to the charging bar, a first electrical connection element secured to the charging bar and electrically connected to the external battery and a second electrical connection element secured to the holding device and electrically connected to the main battery.The first electrical connection element is configured to cooperate with the second electrical connection element, so as to establish an electrical connection between the first electrical connection element and the second electrical connection element, only when the screen is in a retracted configuration. Thus, to recharge the main battery, a user of the concealment device can attach the external battery to the charging bar when the screen is in the deployed configuration, then control the raising of the screen to its retracted position so as to connect the external battery to the main battery via the first and second electrical connection elements, to allow the main battery to be recharged from the external battery.This method of recharging the main battery is generally satisfactory but requires user intervention and a complete movement of raising the screen in the user's presence, which it would be desirable to avoid.

[0006] The aim of the present invention is to propose a method for controlling a concealment device comprising a main battery secured to the holding device and a secondary battery secured to the charging bar, making it possible to efficiently recharge the main battery from the secondary battery without user intervention and by optimizing the recharging of the two batteries.

[0007] To this end, the invention relates to a method for controlling a screening device, the screening device comprising: - a screen, - a holding device, for supporting the screen, a first end of the screen being attached to the holding device, - a load bar, a second end of the screen being fixed to the load bar, - an electromechanical actuator, configured to drive the screen between a retracted configuration and a deployed configuration, the load bar then being moved relative to the holding device, - an electronic control unit, configured to control the electromechanical actuator, - an electrical power supply device, comprising at least: • a main battery, the main battery being integral with the holding device, the main battery being configured to electrically power the electromechanical actuator in order to drive the screen between its retracted configuration and its deployed configuration, • a secondary battery, the secondary battery being attached to the charging bar, • a first electrical connection element, the first electrical connection element being secured to the charging bar, the first electrical connection element being electrically connected to the secondary battery, • a second electrical connection element, the second electrical connection element being secured to the holding device, the second electrical connection element being electrically connected to the main battery, the second electrical connection element being configured to cooperate with the first electrical connection element when the screen is in the retracted configuration.

[0008] According to the invention, the method for controlling the occultation device comprises: - a measurement of the charge level of the main battery, - a measurement of a charge level of the secondary battery, - a comparison, by the electronic control unit, of the measured charge level of the main battery with a first predetermined charge level, - a comparison, by the electronic control unit, of the measured charge level of the secondary battery with a second predetermined charge level, a main condition being fulfilled if the measured charge level of the main battery is lower than the first predetermined charge level and if the measured charge level of the secondary battery is higher than the second predetermined charge level, - if the main condition is met, an actuation command of the electromechanical actuator, by the electronic control unit, to drive the screen to its retracted configuration, so as to establish an electrical connection between the secondary battery and the main battery via the first electrical connection element and the second electrical connection element, and - once the electrical connection is established between the secondary battery and the main battery, a recharge of the main battery from the secondary battery.

[0009] Thus, the screen is raised automatically, without intervention by the user of the occultation device, when the charge levels of the main battery and the secondary battery allow the main battery to be recharged optimally.

[0010] In this way, unnecessary raising of the screen is avoided. The number of raisings of the screen intended to allow the main battery to be recharged is then reduced, thus limiting the disturbance to the user and allowing the occulting device to fulfill its role, in the deployed position, of sun protection and / or occultation.

[0035] [Fig.6] [Fig.6] is a flowchart illustrating a method of controlling a occultation device, the control method being in accordance with the invention.

[0036] 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.

[0037] The closing, concealing or sun protection device 3 is hereinafter called the “concealing device”. The concealing device 3 comprises the screen 2.

[0038] 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.

[0039] 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].

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Advantageously, the concealment device 3 comprises a holding device 9, 23.

[0044] 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.

[0045] 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 occulting 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.

[0046] 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.

[0059] In the case of a roller blind, the high position corresponds to a predetermined high end-of-travel position, preferably defined by the user.

[0060] 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.

[0061] 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. The term deployed configuration refers to a configuration where the loading bar 8 is further away 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 the retracted configuration, it is in the deployed configuration.

[0113] 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.

[0114] Advantageously, the electromechanical actuator 11 further comprises a torque support 21, which may also be called an “actuator head”. The torque support 21 is arranged at the first end 17a of the casing 17 of the electromechanical actuator 11, in the assembled configuration of the electromechanical actuator 11.

[0115] The torque support 21 makes it possible to take up the forces exerted by the electromechanical actuator 11 and, in particular, to ensure the take-up of the forces exerted by the electromechanical actuator 11, in particular the torque exerted by the electromechanical actuator 11, by the structure of the building B. The torque support 21 advantageously makes it possible to take up, in addition, forces exerted by the winding tube 4, in particular the weight of the winding tube 4, of the electromechanical actuator 11 and of the screen 2, and to ensure the take-up of these forces by the structure of the building B.

[0116] Thus, the torque support 21 of the electromechanical actuator 11 makes it possible to fix the electromechanical actuator 11 to the holding device 9, 23, in particular to one of the supports 23 or to one of the cheeks 10 of the box 9.

[0117] Advantageously, the torque support 21 projects at the first end 17a of the casing 17 of the electromechanical actuator 11, in particular the end 17a of the casing 17 receiving the crown. The crown constitutes, in other words is configured to constitute, a bearing for guiding the winding tube 4 in rotation, in the assembled configuration of the occulting device 3.

[0118] Advantageously, the torque support 21 of the electromechanical actuator 11 can also make it possible to close the first end 17a of the casing 17.

[0119] Furthermore, the torque support 21 of the electromechanical actuator 11 can make it possible to support at least part of the electronic control unit 15.

[0120] Advantageously, the torque support 21 comprises a first part 21a and a second part 21b.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] Advantageously, the electronic control unit 15 can be arranged at least partly inside the casing 17 of the electromechanical actuator 11.

[0131] 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.

[0132] 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.

[0133] Here and as illustrated in [Fig.3], the torque support 21 comprises a cover 22. In addition, 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.

[0134] 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 source.

[0135] 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.

[0136] Here, the torque support 21 comprises a single button.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] Here, the torque support 21 comprises a single display device.

[0141] The number of display devices is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] When the electromechanical actuator 11 is operated, the electric motor 16 and the reducer 19 rotate the output shaft 20. In addition, the output shaft 20 of the electromechanical actuator 11 rotates the tube winding 4 via the connecting element.

[0146] Thus, the winding tube 4 rotates the screen 2 of the occulting device 3, so as to open or close the opening 1.

[0147] The electrical energy supply device is now described with reference to FIGS. 4 and 5.

[0148] The electrical power supply device comprises a first electrical connection element 44 and a second electrical connection element 46.

[0149] 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.

[0150] 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 connected to the charging connector 40.

[0151] 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.

[0152] 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.

[0153] 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 that the first and second electrical connection elements are opposite each other. A connection position of the load 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.

[0154] 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 in proximity to the second electrical connection element 46 or, preferably, against, i.e. in 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.

[0155] In this way, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is implemented without an electrical power cable connecting the first electrical connection element 44 to the second electrical connection element 46, so as to guarantee the reliability of this electrical connection and to minimize the costs of obtaining the occultation device 3.

[0156] In the example, when the screen 2 is in the retracted configuration and the charging bar 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.

[0157] 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.

[0158] 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-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-type pins.

[0159] 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.

[0160] 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.

[0161] In the example, the electrical power supply device 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.

[0162] Advantageously, the electrical energy supply device 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.

[0163] Advantageously, the electrical energy supply device 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.

[0164] 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.

[0165] The secondary battery 54 is electrically connected to the first electrical connection element 44.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] Thus, the main battery 24 is rechargeable either from the external electrical power supply source 42, or from the photovoltaic solar panel 52 via the secondary battery 54. The photovoltaic solar panel 52 thus forms an internal electrical power supply source for the occultation device 3. In other words, the external electrical power supply source 42 and the photovoltaic solar panel 52 are two separate electrical power supply sources for recharging the main battery 24.

[0171] Advantageously, the electrical energy supply device 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.

[0172] 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 with electrical power.

[0173] 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 from an alternating current mains power supply network.

[0174] Advantageously, the external electrical power supply source 42 is connected to the charging connector 40 using a corresponding connector (not shown) at the end of an electrical power supply cable 43.

[0175] 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 in failure or in a variant in which the occultation device 3 does not have a photovoltaic solar panel.

[0176] 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.

[0177] 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 movement axis Z and perpendicular to the rotation axis X. By "at the level of the holding device", it is meant that the hooking 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.

[0178] In the example, the force F is exerted along an axis Y which is perpendicular to the displacement axis Z and to the rotation axis X, i.e. perpendicular to the screen 2. In other words, in the example, the hooking direction DA is parallel to the axis Y

[0179] The force F tends to bring the load bar 8 closer to the holding device 9, 23, in 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] In practice, the magnet is oriented so that the magnetic field generated by the magnet is maximum along the direction of attachment DA.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] Thus, during the end of the rise 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, in the direction of attachment DA: this placement 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 hooking direction DA, due to the force F generated by the magnet. According to the hooking 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 according to the hooking direction DA until the first electrical connection element 44 comes into abutment against the second electrical connection element 46.

[0190] The hooking device 60 is configured to compensate, in other words compensates, an offset between the first electrical connection element 44 and the second electrical connection element 46, parallel to the hooking direction DA, i.e. 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.

[0191] The construction of the occulting device 3, and more precisely of the electrical power supply device and 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] In addition, the electrical connection of the electrical power supply source external 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 on 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.

[0196] 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.

[0197] Advantageously, the retracted configuration of the screen 2, as well as the high position of the screen, can be determined during the installation of the occulting device 3.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] Thus, following receipt of this signal by the electronic control unit 15, the latter issues a command to stop the electromechanical actuator 11.

[0203] 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.

[0204] In a variant of the invention not shown, the occultation device 3 does not comprise a photovoltaic panel 52.

[0205] In a variant of the invention not shown, the concealment device 3 does not include a charging connector 40.

[0206] 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.

[0207] A method 100 for controlling the occultation device 3 is now described with reference to [Fig.6].

[0208] The control method 100 aims to allow the recharging of the main battery 24 from the electrical energy stored by the secondary battery 54 without requiring intervention from a user of the occultation device 3 or disturbing the user.

[0209] For this, the control method 100 evaluates the quantity of electrical energy stored by the main battery 24 and the quantity of electrical energy stored by the secondary battery 54, estimates on this basis whether a recharge of the main battery 24 by the secondary battery 54 is desirable, then determines the appropriate time to carry out this recharge.

[0210] The control method 100 begins with a first step 110, when the screen 2 is in the deployed configuration, that is to say when there is no electrical connection between the secondary battery 54 and the main battery 24.

[0211] In the first step 110, the charge level of the main battery 24 and the charge level of the secondary battery 54 are measured. These charge levels are for example expressed as a percentage of the electrical energy storage capacity of the main battery and the secondary battery respectively, or expressed as the quantity of energy stored by the main battery and the secondary battery respectively, for example in milliampere-hours (mAh) or in milliwatt-hours (mWh).

[0212] In practice, the electrical energy storage capacities of the main battery and the secondary battery respectively are values ​​known and recorded by the electronic control unit 15, linked to the technical characteristics of the main and secondary batteries, or are values ​​measured when the main and secondary batteries respectively are recharged to their maximum capacity.

[0213] Preferably, to measure the charge level of the main battery 24, the electronic control unit 15 comprises an upper measuring module 62, integral with the holding device 9, 23. In the example, the upper measuring module 62 is arranged in the casing 17 of the electromechanical actuator 11, as visible in [Fig.3].

[0214] Advantageously, the upper measurement module 62 is integrated into the first electronic card 15a or into the second electronic card 15b or is connected to the first electronic card 15a and / or to the second electronic card 15b, for example using an electric wire.

[0215] Preferably, to measure the charge level of the secondary battery 54, the electronic control unit 15 comprises a lower measurement module 64, which is remote, integral with the charging bar 8. In [Fig.4], the charging bar 8 is partially masked to make the lower measurement module 64 visible.

[0216] Advantageously, the electronic control unit 15 comprises communication means, in particular radio communication means, comprising at least one transmitter and one receiver, adapted to communicate the charge level measurements of the secondary battery 54 carried out by the lower measurement module 64 to the first electronic card 15a and / or the second electronic card 15b.

[0217] Once the measurements of the charge levels of the main battery 24 and the secondary battery 54 have been carried out, the control method 100 continues with a second step 120.

[0218] During the second step 120, the electronic control unit 15 compares the measured charge level of the main battery 24 with a first predetermined charge level and compares the measured charge level of the secondary battery 54 with a second predetermined charge level.

[0219] The first and second predetermined charge levels are expressed in the same way as the measured charge levels of the main battery 24 and the secondary battery 54, for example as a percentage or in milliampere-hours or milliwatt-hours. By way of non-limiting example, the first predetermined charge level is equal to 80% of the electrical energy storage capacity of the main battery 24 and the second predetermined charge level is equal to 80% of the electrical energy storage capacity of the secondary battery 54.

[0220] Advantageously, the first or second predetermined charge level is not a fixed value. It is defined for example on the basis of criteria related to the battery or its environment (age of the battery, ambient temperature, etc.). The first predetermined charge level is further advantageously dependent on the energy storage capacity of the main battery 24, the second predetermined charge level, the maximum capacity of the secondary battery 54 and a possible efficiency associated with the transfer of energy between the secondary battery 54 and the main battery 24.

[0221] Based on these comparisons, a main condition is met if the measured charge level of the main battery 24 is lower than the first predetermined charge level and if the measured charge level of the secondary battery 54 is higher than the second predetermined charge level.

[0222] At the end of the second step 120, if the main condition is not met, then the control method 100 ends. If the main condition is met, then the control method continues with steps 130 to 170, which are op- tional.

[0223] The main condition verified in step 120 thus makes it possible to ensure that the quantities of energy stored by the main battery 24 and the secondary battery 54 make it relevant to recharge the main battery 24 from the secondary battery 54, without requiring intervention from a user of the occultation device 3. Indeed, this main condition makes it possible in practice to verify whether the main battery 24 is sufficiently discharged to require recharging and whether simultaneously the secondary battery 54 is sufficiently charged to allow the main battery to be recharged effectively. If this main condition is met, then the control method continues and otherwise, the control method ends.An unnecessary raising of the screen 2 in the retracted configuration not allowing the main battery 24 to be recharged effectively, because the main battery is already sufficiently charged and / or because the secondary battery 54 is not sufficiently charged, is thus avoided.

[0224] Each of the steps 130 to 170 introduces an additional criterion for determining whether a command to actuate the electromechanical actuator 11, by the electronic control unit 15, to drive the screen 2 to its retracted configuration must be issued or must not be issued. These additional criteria make it possible to improve the control method 100, in particular by avoiding unnecessary movements of the screen 2 and by ensuring efficient recharging of the main battery 24.

[0225] During the third step 130, the electronic control unit 15 determines a last recharge time, corresponding to a recharge of the main battery 24 carried out last, then calculates a first duration, corresponding to a duration separating the present instant from the last recharge time. On the basis of this calculation, a last recharge condition is fulfilled if the first duration is greater than a first predetermined duration. By way of non-limiting example, the first predetermined duration is equal to ten days.

[0226] The time of the last recharge is for example determined using a time counter, integrated into the electronic control unit 15, which counts the time elapsed since the last recharge of the main battery 24.

[0227] At the end of the third step 130, if the last recharge condition is not met, then the control method 100 continues with a fourth step 140, which is an optional step. If the last recharge condition is met, then the control method continues with an eighth step 180, during which a command to actuate the electromechanical actuator 11, by the electronic control unit 15, to drive the screen 2 to its retracted configuration, is issued, and during which the main battery 24 is recharged from the secondary battery 54.

[0228] The last recharge condition verified in step 130 thus makes it possible to check the time elapsed since the last recharge of the main battery 24 and, if this time is considered too long, i.e. greater than the first duration, to force the driving of the screen 2 in the retracted configuration without taking into account the additional criteria of steps 140 to 170. In other words, when the last recharge condition is met, step 130 makes it possible to force a recharge of the main battery 24 by the secondary battery 54 when the last recharge time is too far away. If the last recharge time occurred within a normal time, i.e. less than the first duration, then the control method 100 continues with the fourth step 140 since the last recharge condition is not met.

[0229] The fourth step 140 is implemented only when the electronic control unit 15 is programmed to control the actuation of the electromechanical actuator 11 to drive the screen 2 to its retracted configuration at a programmed time.

[0230] For example, the electronic control unit 15 is programmed to drive the screen 2 to its retracted configuration every day at a fixed time, the programmed time thus corresponding to this fixed time, or to the time of sunset, or to the time of sunrise, or when an interior temperature measured within the building B becomes higher than an exterior temperature measured outside the building B. Other criteria may be used to program the driving of the screen 2 to its retracted configuration. For example, the programmed time includes a time learned by a self-learning mechanism based on usage habits.

[0231] In practice, the programmed time corresponds to the time of a training session programmed from the screen 2 until its retracted configuration by the electronic control unit 15 occurring first after the present time. Furthermore, the present time here corresponds to the execution time of the fourth step 140 of the control method 100.

[0232] During the fourth step 140, the electronic control unit 15 calculates a second duration, the second duration corresponding to a duration separating the programmed instant from the present instant. On the basis of this calculation, a first auxiliary condition is fulfilled if the second duration is greater than a second predetermined duration. By way of non-limiting example, the second predetermined duration is equal to five hours.

[0233] At the end of the fourth step 140, if the first auxiliary condition is not met, then the control method 100 ends. If the first auxiliary condition is met, then the control method continues with a fifth step 150, which is an optional step.

[0234] The first auxiliary condition verified in step 140 thus makes it possible to verify whether a return of the screen 2 to its retracted configuration is programmed at a time close to the present time, and to avoid driving the screen to its retracted configuration if this is the case. Indeed, in such a situation, it is preferable to wait for the programmed time to drive the screen 2 into the retracted configuration and recharge the main battery 24 from the secondary battery 54, rather than driving the screen 2 into the retracted configuration at the present time.Indeed, for a user of the concealment device 3, driving the screen 2 from its deployed configuration to its retracted configuration solely to recharge the main battery 24 constitutes a disturbance, whereas taking advantage of driving the screen 2 to its retracted configuration already programmed to then recharge the main battery 24 has no impact, since the movement of the screen would have taken place even in the absence of the control method 100, independently of the need to recharge the battery 24. An unnecessary raising of the screen 2 in the retracted configuration, because a raising is already programmed soon, is thus avoided.

[0235] During the fifth step 150, the electronic control unit 15 checks whether, at the present time, the surrounding conditions are night conditions. The present time here corresponds to the time of execution of the fifth step 150 of the control method 100. The night conditions comprise at least two pieces of information: a night situation, as opposed to a day situation and, preferably, an activated night mode setting, as opposed to a non-activated night mode.

[0236] The night situation detection can be carried out according to several methods. Preferably, the electronic control unit 15 checks whether it is night using the photovoltaic solar panel 52, by measuring, during step 150, the electrical voltage generated by the photovoltaic solar panel, then by checking that the measured electrical voltage generated by the photovoltaic solar panel is lower than a predetermined voltage value. For example, the predetermined voltage value is equal to half the no-load voltage measured at 1000W / m2, or to half the nominal voltage of the associated battery. In practice, the fact that the measured electrical voltage generated by the photovoltaic solar panel is lower than the predetermined voltage value indicates that the photovoltaic solar panel is not producing electrical current and therefore that it is not exposed to solar radiation.

[0237] Alternatively, or in addition, the electronic control unit 15 detects the night situation using a brightness sensor, not shown, integrated into the occultation device 3, or on the basis of data supplied to the electronic control unit 15 indicating the sunrise and sunset times for the day corresponding to the present moment.

[0238] The night mode setting can be activated or not by the user. This setting can be activated individually for each occultation device, so that it is for example possible to activate the night mode in the different rooms of the building with the exception of the bedrooms. When the night mode setting is activated, the electronic control unit favors a recharge by energy transfer from the secondary battery to the main battery in a night situation. In other words, when the night mode setting is activated, the electronic control unit 15 is authorized by the user to control the actuation of the electromechanical actuator 11 to its retracted configuration during the night.If the blackout device has a sun protection function, this activated night mode setting makes sense to encourage charging movements during the night and minimize charging movements during sunny days.

[0239] Conversely, an activated day mode setting could allow for favoring a charging movement in a daytime situation. Thus, the occultation device can continue to fulfill its function of closing and protecting the privacy of the interior space of the building during the night. The fifth step would then operate in a similar manner to that described above, but on the basis of daytime situation detection.

[0240] If the electronic control unit 15 finds that it is actually night at the present time, then the electronic control unit 15 calculates a third duration, corresponding to a duration separating the present time from a sunrise time, corresponding to a sunrise occurring first after the present time. On the basis of this calculation, a second auxiliary condition is fulfilled if the third duration is greater than a third predetermined duration. By way of non-limiting example, the third predetermined duration is equal to three hours.

[0241] At the end of the fifth step 150, if the second auxiliary condition is not met, then the control method 100 ends. If the second auxiliary condition is met, then the control method continues with a sixth step 160, which is an optional step.

[0242] The second auxiliary condition verified in step 150 thus makes it possible to verify whether a sufficiently long duration to recharge the main battery 24 from the secondary battery 54 is available before daybreak. Thus, it is possible to recharge the secondary battery during step 180 and then lower the screen back into the deployed configuration during step 190, as described below, before sunrise, so that a user of the occulting device 3 is not disturbed by this recharging of the main battery. Indeed, a movement of the screen 2 during the night is generally less disturbing for a user of the occulting device 3 than a movement of the screen during the day, since users are generally asleep during the night. In this way, since the main battery 24 is recharged during the night, a user of the occulting device 3 generally does not notice that the screen 2 has been successively raised to the retracted configuration and then lowered back to its original configuration.

[0243] The sixth step 160 is implemented only when the electronic control unit 15 is configured to detect the presence of a user, i.e. the presence of a user in the vicinity of the occultation device 3, and comprises the hardware and software means for detecting this presence. By “in the vicinity of the occultation device 3”, it is meant that a user of the occultation device 3 is located in the same room as the occultation device 3, or in the building B, or at a distance from the occultation device 3 less than a predetermined distance, for example 2 meters.

[0244] The detection of a user's presence is carried out, for example, using motion sensors, from information coming from connected objects, such as a connected lock or an alarm, or from geolocation data coming from a connected device of the user, such as a smartphone.

[0245] During the sixth step 160, the electronic control unit 15 detects whether, at the present moment, a user is present, in particular is present near the occulting device 3. A third auxiliary condition is then fulfilled if the presence of no user is detected, in particular if the presence of no user is detected near the occulting device.

[0246] At the end of the sixth step 160, if the third auxiliary condition is not met, then the control method 100 ends. If the third auxiliary condition is met, then the control method continues with a seventh step 170, which is an optional step.

[0247] The third auxiliary condition verified in step 160 thus makes it possible to verify whether recharging of the main battery 24 can be carried out in the absence of a user of the concealment device 3, and thus without disturbing the user, since the latter will not be able to see that the screen 2 has been successively raised to the retracted configuration and then lowered back into its original position to recharge the main battery 24.

[0248] Preferably, during step 160, the electronic control unit 15 further determines a fourth duration, corresponding to a duration separating the present instant from a return instant, corresponding to an instant at which a user becomes present again, in particular becomes present again in the vicinity of the occultation device 3. The third auxiliary condition is then fulfilled if, in addition to the fact that the presence of no user is detected, the fourth duration is greater than a fourth predetermined duration. By way of non-limiting example, the fourth predetermined duration is equal to three hours. This additional condition thus makes it possible to check whether a sufficiently long duration to recharge the main battery 24 from the secondary battery 54 is available before a user returns. Thus, it is possible to recharge the secondary battery during step 180 and then lower the screen back into the deployed configuration during step 190, as described below, before a user of the occultation device 3 returns, so that the user is not disturbed by this recharging of the main battery.

[0249] During the seventh step 170, the charge level of the main battery 24 and the charge level of the secondary battery 54 are determined, being expressed in quantity of energy stored by the main battery and the secondary battery respectively, for example in milliampere-hour (mAh) or in milliwatt-hour (mWh). Advantageously, these charge levels expressed in quantity of energy stored by the main battery and the secondary battery respectively are determined on the basis of the measurements carried out during the first step 110, for example using the upper 62 and lower 64 measuring modules.

[0250] Then, the electronic control unit 15 calculates the difference between the electrical energy storage capacity of the main battery 24 and the measured quantity of electrical energy stored by the main battery 24. A fourth auxiliary condition is then fulfilled if the calculated difference is greater than the measured quantity of electrical energy stored by the secondary battery 54.

[0251] At the end of the seventh step 170, if the fourth auxiliary condition is not met, then the control method 100 ends. If the fourth auxiliary condition is met, then the control method continues with an eighth step 180.

[0252] The fourth auxiliary condition verified in step 170 thus makes it possible to verify that the recharging of the main battery 24 makes it possible to transfer a maximum of energy from the secondary battery 54 to the main battery. This makes it possible to recharge the main battery 24 only when the quantity of electrical energy available to carry out this recharging is maximum, thus increasing the duration between two recharges of the main battery 24. Since the main battery 24 is recharged less often, a user of the occultation device 3 is disturbed less often.

[0253] It should be noted that the electrical energy storage capacity of the main battery 24 may be chosen to be lower than a maximum electrical energy storage capacity of the main battery, in order to avoid degrading the battery over time. It is, for example, around 80% to 95% of the maximum storage capacity of the main battery.

[0254] Similarly, the secondary battery 54 is not discharged 100% or entirely to the main battery 24, so as to maintain an energy reserve of operation for the lower measuring module 64. For example, a minimum charge level of 10% is maintained. Optionally, to take this energy reserve into account, the fourth auxiliary condition is then preferably fulfilled if the calculated difference is greater than the measured quantity of electrical energy stored by the secondary battery 54 reduced by 10% of the electrical energy storage capacity of the secondary battery.

[0255] During the eighth step 180, the electronic control unit 15 issues a command to actuate the electromechanical actuator 11, to drive the screen 2 to its retracted configuration, so as to establish an electrical connection between the secondary battery 54 and the main battery 24 via the first electrical connection element 44 and the second electrical connection element 46. Then, once the electrical connection has been established between the secondary battery 54 and the main battery 24, the main battery 24 is recharged from the secondary battery 54.

[0256] The eighth step 180 then ends once the recharging of the main battery 24 from the secondary battery 54 is complete.

[0257] Preferably, during the recharging of the main battery 24, the charge level of the secondary battery 54 is monitored and the eighth step 180 ends when the charge level of the secondary battery reaches a predetermined discharge level, corresponding for example to a charge level equal to 10% of the maximum charge of the secondary battery 54. Once the discharge level is predetermined, the electrical connection between the secondary battery and the main battery is cut, thus ending the recharging of the main battery. A deep discharge of the secondary battery 54 is thus avoided, which allows the secondary battery 54 to continue to electrically supply electronic components integrated into the charging bar 8, such as for example the lower measuring module 64.

[0258] It is then understood that the screen 2 is only driven towards its retracted configuration, and that the main battery 24 is only recharged, if the main condition and the first to fourth auxiliary conditions are met, or if the main condition and the last recharge condition are met.

[0259] Otherwise, if the main condition is not met, or if the last recharge condition and at least one of the first to fourth auxiliary conditions are not met, the control method is terminated and the screen is not driven towards its retracted configuration.

[0260] Furthermore, steps 130 to 170 are optional steps, which are carried out or not depending on the preferences of the user of the occultation device 3. These preferences are for example defined at the time of commissioning of the occultation device 3. Thus, the third step 130, and / or one or more of steps 140 to 170, can be partially carried out and, depending on the configuration, the conditions cor are then not verified or the third step 130, and / or one or more of the steps 140 to 170, may not be carried out. For example, a user of the occultation device 3 may decide by suitable parameterization, that the control method 100 does not carry out the verification of the first auxiliary condition of step 140, if he considers that a recharge of the main battery 24 is not disturbing even if a movement is already programmed shortly after the present moment, or may decide that the control method 100 does not carry out the verification of the second auxiliary condition of step 150, if a movement of the screen 2 during the day does not disturb him or if the user is absent during the day.

[0261] After the eighth step 180, the control method 100 comprises a ninth step 190. During the ninth step 190, the electronic control unit 15 issues a command to actuation the electromechanical actuator 11, to drive the screen 2 from its retracted configuration to a deployed configuration, for example its original configuration. In other words, the ninth step 190 corresponds to a step of deployment of the screen 2. Advantageously, the command to actuation the electromechanical actuator 11 is issued automatically once the recharging of the main battery 24 by the secondary battery 54 is complete.

[0262] Thus, at the end of the ninth step 190, the screen 2 returns to the same configuration as at the start of the control method 100, i.e. its original configuration or another deployed configuration.

[0263] Alternatively, the command to actuation the electromechanical actuator 11 during the ninth step 190 is issued by a user, or is issued at a programmed time. For example, the electronic control unit 15 is programmed to drive the screen 2 from its retracted configuration to its original configuration, or to another deployed configuration at a fixed time, the programmed time thus corresponding to this fixed time, or at the time of sunset, or at the time of sunrise, or when an interior temperature measured within the building B becomes lower than an exterior temperature measured outside the building B. Other criteria may be used to program the driving of the screen 2 from its retracted configuration.

[0264] At the end of the ninth step 190, the control method 100 is terminated. The control method 100 is then executed again, starting with the first step 110 after a predetermined waiting time, for example equal to one hour.

[0265] Alternatively to the ninth step 190, after the eighth step 180, i.e. once the recharging of the main battery 24 from the secondary battery 54 is complete, the electrical connection between the secondary battery and the battery main power is cut, screen 2 is kept in the retracted configuration and the control method 100 is terminated. In other words, at the end of the control method 100, screen 2 does not return to its original configuration and remains in the retracted configuration.

[0266] Preferably, if the control method 100 is terminated at the end of one of the steps 120 and 140 to 170, i.e. if the main condition or at least one of the first to fourth auxiliary conditions is not met, then the control method 100 is executed again, starting with the first step 110 after a predetermined waiting time, for example equal to one hour.

[0267] The control method 100 makes it possible to recharge the main battery 24 from the secondary battery 54 in an optimized manner while minimizing the disturbance of a user of the occultation device 3.

[0268] Thanks to the control method of the invention, it is thus possible to establish an objective criterion for choosing when to raise the screen 2 in the retracted configuration and thus recharge the main battery from the secondary battery, without intervention by a user of the occulting device 3. The disturbance of the user of the occulting device 3 is thus minimized. In addition, the control method of the invention allows the user of the occulting device 3 to choose which are the secondary criteria for deciding whether or not a recharge of the main battery 24 should be carried out, according to his personal preferences.

[0269] Furthermore, the secondary battery 54 being preferentially recharged using the photovoltaic solar panel 52, that is to say without intervention from a user of the occultation device 3, then the occultation device can operate in total autonomy, without requiring intervention from a user of the occultation device 3 to recharge the main 24 and secondary 54 batteries.

[0270] The choice of the first and second load levels can be made automatically according to a functional priority criterion defined by the user. For example, the user can select this functional priority criterion from several indicators, for example ranging from 1 to 4, each representing a functional priority level with respect to the disturbance. Thus, a level 1 indicator prioritizes the assurance of operation of the occultation device with a higher risk of unwanted movements than for the following indicators, a level 4 indicator prioritizes the discretion of the operation with a higher risk of non-operation than for the previous indicators.

[0271] Thus, the first charge level will be chosen higher and the second charge level will be chosen lower if a level 1 indicator is chosen by the user than if a next level indicator is chosen.

[0272] The automatic reloading movements may be performed at least partially at slow speed. This allows the user to be aware that these movements are for recharging purposes and this also minimizes the acoustic impact of activating the electromechanical actuator and moving the screen.

[0273] The operation of the occultation device, the different capacities measured over time can be stored in memory to improve the determinations of first, second, third or fourth duration and thus make it possible to improve the possibilities of autonomous operation of the occultation device.

[0274] In the various steps of the method, alerts may be issued to the user, for example via the display elements at the level of the occultation device itself or via messages transmitted by the electronic control unit 15.

[0275] The embodiments and variants envisaged may be combined to generate new embodiments of the invention, without departing from the scope of the invention.
