Description

TECHNICAL FIELD

[0001] The present invention relates to an electromechanical actuator for a closing, screening or sunshade system, i.e. an electromechanical actuator for a closing, screening or sunshade system, and to an electric drive comprising such an actuator. The present invention also relates to a closing, screening or sunshade device comprising a screen moved by such an electromechanical actuator or comprising such an electric drive.

[0002] Generally, the present invention relates to the field of screening devices comprising an electric drive moving a screen between at least one first position and at least one second position. BACKGROUND

[0003] The electric drive generally comprises an electromechanical actuator of a movable closing, screening or sunshade element, such as a shutter, a door, a gate, a screen or any other equivalent device, hereinafter referred to as a screen.

[0004] Electromechanical actuators for closing, screening or sunshade systems are known, comprising a housing, a torque support, a power supply lead, an electric motor, an electronic control unit and a cover. The torque support is arranged at one end of the housing and cooperates with a holding device to bear the load applied by the electromechanical actuator. The power supply lead is configured to be connected to an electrical energy supply network. The electric motor is mounted inside the housing, supplied with electrical energy through the power supply lead. The electronic control unit comprises at least one electronic board arranged inside the torque support. The cover is mounted on the head of the torque support.

[0005] When installing such an electromechanical actuator, it is generally necessary to adapt the torque support to the support of the holding device. There are various supports having different shapes with which the torque support must be compatible to be installed.

[0006] It is common practice to add an adapter to the torque support, thus achieving the connection between the support of the holding device and the torque support without having to adjust the shape of the torque support. Such an adapter is generally attached to one end of the torque support.

[0007] However, the drawback of these adapters is that they are inserted between the support of the holding device and the torque support, which generates an additional thickness at the end of the electromechanical actuator. This additional thickness causes a gap to appear around the screen, between the screen and the lateral edges of the opening in which the closing, screening or sunshade system is installed, thus causing light leakage. The screening produced by the screen is therefore lower. The addition of an adapter is therefore not aesthetic and does not provide a satisfactory screening effect. SUMMARY

[0008] The present invention aims to remedy these drawbacks and proposes an electromechanical actuator that can be easily adapted to the support of a holding device without degrading the screening effect provided by the screen belonging to the device, as well as a closing, screening or sunshade device comprising such an electromechanical actuator.

[0009] In this respect, according to a first aspect, the present invention relates to an electromechanical actuator for driving a winding tube of a closing, screening or sunshade device, the electromechanical actuator comprising at least:

[0012] - a power supply lead configured to be connected to an electrical energy supply network.

[0013] - an electric motor mounted inside the housing, the electric motor being supplied with electrical power via the power supply lead,

[0014] - an electronic control unit comprising at least one electronic board,

[0015] - a cover mounted on the head of the torque support, the cover comprising a base and a lateral surface.

[0016] According to the invention, the electronic board is arranged inside the accommodation of the torque support, the cover closing the accommodation of the torque support. Furthermore, the torque support comprises a mounting plate fixed to one end of the head of the torque support by being mounted in a cutout of the lateral surface of the cover. Moreover, the mounting plate is provided with an opening configured to cooperate with a protruding portion of the fixed support of the holding device to take up the load exerted by the electromechanical actuator.

[0017] Thanks to the invention, the mounting plate is integrated into the electromechanical actuator so that it does not protrude from the cover and does not create an overhang at the end of the electromechanical actuator. This means that the distance between the support of the holding device and the electromechanical actuator is minimal, which improves the screening effect provided by the screen of the device comprising such an electromechanical actuator.

[0018] According to advantageous but non-mandatory aspects of the invention, the electromechanical actuator comprises one or more of the following features, used alone or in any technically feasible combination:

[0019] - the mounting plate holds the assembled cover on the torque support.

[0020] - the cover comprises a periphery and the mounting plate comprises a shoulder, the periphery and the shoulder having a complementary shape and, in the assembled configuration of the electromechanical actuator, the shoulder abuts against the periphery.

[0021] - the mounting plate and the cover are independently interchangeable.

[0022] - the outer surface of the mounting plate is flush with the lateral surface of the cover.

[0023] - the two main surfaces of the mounting plate are substantially flat, do not have a relief and are parallel to each other.

[0024] - the torque support further comprises an opening configured to receive each protruding portion of the support of different shape, and the opening of the mounting plate is aligned with the opening of the torque support.

[0025] - the opening of the mounting plate comprises at least one bearing surface.

[0026] - the opening of the mounting plate comprises a plurality of arms, each arm having two bearing surfaces.

[0027] - the torque support comprises a bracket configured to hold the torque support with respect to the holding device, the mounting plate comprises a recess, the shape of the recess being complementary to the shape of the bracket, and in the assembled configuration of the electromechanical actuator, the bracket of the torque support is arranged in the recess of the mounting plate.

[0028] - the base of the cover comprises at least one opening configured to face an electronic component carried by the electronic board.

[0029] According to a second aspect, the application relates to a screening device for a closing, screening or sun shading device, the screening device comprising a winding tube, a winding screen located on the winding tube, an electromechanical actuator driving the movement of the screen, and a holding device comprising at least one fixed support, the electromechanical actuator being an electromechanical actuator according to the application and as described above, the shape of the opening of the plate being complementary to the shape of the protruding portion of the fixed support, and the opening of the plate being configured to receive this protruding portion.

[0030] According to a third aspect, the application relates to a closing, screening or sun shading device comprising a screen that can be wound on a winding tube and moved by an electromechanical actuator, the electromechanical actuator being an electromechanical actuator according to the application and as described above, or the device comprising a screening device according to the application and as described above.

[0042] First, with reference to Figure 1 and Figure 2 , a device 6 according to a first embodiment of the present application is described, which comprises a closing, screening or sunshade device 3, installed in a building B comprising an opening 1 which is a window or a door. The device 6 is equipped with a screen 2 belonging to the closing, screening or sunshade device 3, in particular an electrically operated blind.

[0043] The closing, screening or shading device 3 is hereinafter referred to as "screening device". The screening device 3 comprises a screen 2.

[0044] The screening device 3 can comprise a screen curtain, for example a rollable canvas, a pleated curtain or a slatted screen curtain. The present invention is applicable to all types of screening devices.

[0045] With reference to Figure 1 and Figure 2 a roller screen curtain comprising an electromechanical actuator according to a first embodiment of the present invention is described.

[0046] The screening device 3 comprises a winding tube 4 and an electric drive 5. The electric drive 5 comprises an electromechanical actuator 11 as shown in Figure 3 and Figure 4 .

[0047] The screen 2 of the screening device 3 is wound onto the winding tube 4 driven by the electric drive 5. Thus, the screen 2 can be moved between a wound position, in particular a high position, and an unwound position, in particular a low position.

[0048] The screen 2 of the screening device 3 is a closing, screening and / or shading screen which can be wound and unwound around the winding tube 4, the inner diameter of which is larger than the outer diameter of the electromechanical actuator 11 so that the electromechanical actuator 11 can be inserted into the winding tube 4 when the screening device 3 is assembled.

[0049] Advantageously, the screening device 3 further comprises a holding device 9, 23.

[0050] Advantageously, the holding device 9, 23 can comprise two fixed supports 23. In particular, in the assembled configuration of the screening device 3, a fixed support 23 is provided at each end of the winding tube 4.

[0051] Thus, the winding tube 4 is held by the fixed supports 23. In Figure 1 only one fixed support 23 is visible. The fixed supports 23 allow the screening device 3 to be mechanically connected to the structure of the building B, in particular to the wall M of the building B.

[0052] Advantageously, the holding device 9, 23 can comprise a box 9. In addition, in particular in the assembled configuration of the screening device 3, at least a portion of the winding tube 4 and of the screen 2 is housed within the box 9.

[0054] Here, as shown in Figure 1 , the fixed supports 23 are also housed within the box 9.

[0055] Advantageously, the box 9 comprises two cheeks 10, as Figure 2 shown. In particular in the assembled configuration of the screening device 3, each end of the box 9 is arranged with one cheek 10.

[0056] In a variant, as Figure 2 shown, the winding tube 4 is held via the box 9, in particular via the cheeks 10 of the box 9, without the use of a support such as the fixed support 23 described above.

[0057] Advantageously, the screening device 3 can also comprise two lateral slides 26, as Figure 2 shown. Each lateral slide 26 comprises a groove 29. In particular in the assembled configuration of the screening device 3, each groove 29 of one of the lateral slides 26 cooperates with, i.e. is configured to cooperate with, a lateral edge 2a of the screen 2 in order to guide the screen 2 during winding and unwinding of the screen 2 around the winding tube 4.

[0058] The electromechanical actuator 11 is for example of the tubular type. This makes it possible to rotate the winding tube 4 around the rotation axis X, so that the screen 2 of the screening device 3 can be unwound or wound up.

[0059] The screen 2 can thus be wound up and unwound on the winding tube 4. In the installed state, the electromechanical actuator 11 is inserted into the winding tube 4.

Furthermore, in the assembled configuration of the screening device 3, a second end of the screen 2, in particular the lower end of the screen 2, is fixed to the load rod 8.

[0062] Here, the canvas forming the screen 2 is made of a textile material.

[0063] In an embodiment not shown, the first end of the screen 2 has a hem through which a rod, in particular made of plastic, is arranged. This hem of the first end of the screen 2 is achieved by sewing the canvas forming the screen 2. When the screen 2 is assembled on the winding tube 4, the hem at the first end of the screen 2 and the rod slide into the groove outside the winding tube 4, in particular over the entire length of the winding tube 4, so that the screen 2 is fixed to the winding tube 4 and can be wound and unwound around the winding tube 4.

[0064] In any case, the first end of the screen 2 is arranged at the holding device 9, 23 so that it remains above the opening 1 in the assembled configuration of the screening device 3.

[0065] In the case of a roller blind, the upper rolled-up position corresponds to a predetermined upper end-of-travel position, or to the support of the load bar 8 of the screen 2 against the edge of the box 9 of the roller blind 3, and the lower unrolled position corresponds to a predetermined lower end-of-travel position, or to the support of the load bar 8 of the screen 2 against the sill 7 of the opening 1, or to the complete unrolling of the screen 2.

[0142] The torque support 21 makes it possible to withstand the load exerted by the electromechanical actuator 11 and makes it possible in particular to ensure that the load exerted by the electromechanical actuator 11, in particular the torque exerted by the electromechanical actuator 11, is absorbed by the building structure B. Advantageously, the torque support 21 also makes it possible to withstand the load exerted by the winding tube 4, in particular the weight of the winding tube 4, the electromechanical actuator 11 and the screen 2, and to ensure that this load is absorbed by the building structure B.

[0143] The torque support 21 of the electromechanical actuator 11 thus makes it possible for the electromechanical actuator 11 to be fixed to the holding device 9, 23, in particular to one of the fixed supports 23 or to one of the cheeks 10 of the box 9.

[0144] Advantageously, the torque support 21 protrudes from the first end 17a of the casing 17 of the electromechanical actuator 11, in particular from the end 17a of the casing 17 which receives the ring 53. In particular in the assembled configuration of the screening device 3, the ring 53 constitutes or is configured to constitute a bearing for the rotational guiding of the winding tube 4.

[0145] Advantageously, the torque support 21 of the electromechanical actuator 11 makes it possible for the first end 17a of the casing 17 to be sheltered.

[0146] Furthermore, the torque support 21 of the electromechanical actuator 11 can support at least part of the electronic control unit 15.

[0147] Advantageously, in particular in the assembled configuration of the electromechanical actuator 11, the torque support 21 is fixed to the casing 17 by means of one or more fastening elements 54. The one or more fastening elements 54 can be, for example, bosses (as shown in Figure 3 、 Figure 5 、 Figure 6 and Figure 8 slots in recesses or combinations thereof.

[0148] Advantageously, the torque support 21 comprises a first portion 21a, referred to as an inner portion, and a second portion 21b, referred to as an outer portion.

[0149] Advantageously, in particular in the assembled configuration of the electromechanical actuator 11, the first portion 21a of the torque support 21 is configured to cooperate with the casing 17 of the electromechanical actuator 11, i.e. the first portion of the torque support cooperates with the casing of the electromechanical actuator. Furthermore, in particular in the assembled configuration of the electromechanical actuator 11 in the screening device 3, the second portion 21b of the torque support 21 is configured to cooperate with the holding device 9, 23, i.e. the second portion of the torque support cooperates with the holding device.

[0150] Advantageously, the structure of the torque support 21, comprising the first portion 21a and the second portion 21b made in a single piece, increases the rigidity of the torque support 21.

[0151] Advantageously, at least one portion of the first portion 21a of the torque support 21 is substantially cylindrical and is arranged inside the housing 17 of the electromechanical actuator 11, in particular in the assembled configuration of the electromechanical actuator 11.

[0152] Advantageously, at least one portion of the second portion 21b of the torque support 21 has an outer diameter greater than the outer diameter of the housing 17 of the electromechanical actuator 11.

[0153] Advantageously, the torque support 21 further comprises a limit stop 33. Moreover, in particular in the assembled configuration of the electromechanical actuator 11, the stop 33 is contiguous with the housing 17 at the first end 17a of the housing 17, i.e. the stop is configured to be contiguous with the housing at the first end of the housing.

[0154] Therefore, the limit stop 33 of the torque support 21 makes it possible to limit the sinking of the first portion 21a of the torque support 21 into the housing 17 along the direction of the rotation axis X.

[0155] Moreover, the limit stop 33 of the torque support 21 delimits the first portion 21a and the second portion 21b of the torque support 21 with respect to each other.

[0156] Therefore, in particular in the assembled configuration of the electromechanical actuator 11, after fitting the torque support 21 inside the housing 17, only the first portion 21a of the torque support 21 is arranged inside the housing 17 of the electromechanical actuator 11, up to the limit stop 33, and the second portion 21b of the torque support 21 extends outside the housing 17.

[0157] Here, the limit stop 33 of the torque support 21 comprises a shoulder, and more particularly the limit stop is made in the form of a flange, in particular having a cylindrical shape and having a straight generatrix.

[0158] Here, as shown in Figures 3 to 5 and Figure 8 in particular in the assembled configuration of the electromechanical actuator 11, the ring 53 is inserted around the torque support 21, in particular around the second portion 21b of the torque support 21.

[0159] In a variant not shown, in particular in the assembled configuration of the electromechanical actuator 11, the ring 53 is inserted around the first end 17a of the housing 17 of the electromechanical actuator 11.

[0160] Advantageously, the output shaft 20 of the electromechanical actuator 11 is arranged inside the winding tube 4 and at least partially outside the housing 17 of the electromechanical actuator 11.

[0161] Here, one end of the output shaft 20 protrudes from the housing 17 of the electromechanical actuator 11, in particular from a second end 17b of the housing 17 opposite the first end 17a.

[0162] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to rotate a connecting element (not shown) connected to the winding tube 4. The connecting element is in the form of a wheel.

[0163] When the electromechanical actuator 11 is switched on, the electric motor 16 and the gear box rotate the output shaft 20. Furthermore, the output shaft 20 of the electromechanical actuator 11 rotates the winding tube 4 via the connecting element.

[0164] Thus, the winding tube 4 winds the screen 2 of the screening device 3, so that the opening 1 is opened or closed.

[0165] The electronic control unit 15 of the electromechanical actuator 11 comprises means (not shown) for detecting obstacles and end-of-travel during winding and unwinding of the screen 2.

[0166] The means for detecting obstacles and end-of-travel during winding and unwinding of the screen 2 are implemented by means of a microcontroller 30 of the electronic control unit 15, in particular by means of an algorithm implemented by the microcontroller 30.

[0167] Here, the electronic control unit 15, in particular the first electronic board 15a and the second electronic board 15b, is supplied with electrical energy by means of the power supply lead 18.

[0168] Advantageously, the electronic control unit 15 is at least partially arranged inside the housing 17 of the electromechanical actuator 11.

[0169] Furthermore, the electronic control unit 15 can be at least partially arranged outside the housing 17 of the electromechanical actuator 11 and, in particular, mounted in the torque support 21.

[0170] Here, in particular in the assembled configuration of the electromechanical actuator 11, the first electronic board 15a of the electronic control unit 15 is arranged inside the housing 17 of the electromechanical actuator 11. Furthermore, in particular in the assembled configuration of the electromechanical actuator 11, the second electronic board 15b is arranged inside the torque support 21 of the electromechanical actuator 11.

[0171] Here, the electronic control unit 15 does not have a housing for receiving the first electronic board 15a. In particular, in the assembled configuration of the electromechanical actuator 11, the first electronic board 15a is held, in particular inserted, on the one hand in the torque support 21, in particular in the third portion 21c of the torque support 21, called central portion, as Figure 4 indicated, on the other hand in a support (not shown) mounted on the end of the electric motor 16.

[0172] Here, the second electronic board 15b is held, in particular inserted, in the central rib of the torque support 21, in particular in the central rib of the second portion 21b of the torque support 21.

[0173] In particular, the second electronic board 15b is arranged within a housing 44 formed in the second portion 21b of the torque support 21, more precisely in the head 21e of the second portion 21b. On the one hand, the housing 44 is delimited by a wall 21d of the torque support 21 along the axis X, which wall 21d is visible in Figure 4 and Figures 6 to 8 and forms one end of the head 21e of the second portion 21b of the torque support 21 along the axis X, on the other hand, the housing is delimited by a wall 21f of the torque support 21, which wall 21f is visible in Figure 6 and Figure 7 is substantially parallel to the wall 21d and is arranged between the wall 21d and the first inner portion 21a of the torque support 21 along the axis X. Furthermore, the outer surface of the head 21e of the second portion 21b is cylindrical.

[0174] Advantageously, the first electronic board 15a and the second electronic board 15b are connected to each other by a connection cable, not shown.

[0175] Furthermore, the electronic board 15b comprises a connector 19 mounted on the printed circuit board 40b and enabling the connection cable between the first electronic board and the second electronic board to be connected.

[0176] Here, as Figure 3 indicated, the torque support 21 further comprises a cover 22. In particular, in the assembled configuration of the electromechanical actuator 11, the cover 22 is mounted on the end of the second portion 21b of the torque support 21, more precisely on the head 21e of the second portion 21b. Furthermore, in the assembled configuration of the electromechanical actuator, the cover 22 closes the housing 44. In Figure 4 and Figure 8 , the cover 22 has been omitted for the sake of clarity.

[0177] The torque support 21 comprises at least one selection device 41, in particular a pushbutton, which can be for example a push-down pushbutton.

[0178] The one or more selection devices 41 are configured, when activated, to perform the adjustment of the electromechanical actuator 11 by one or more configuration modes, to pair the electromechanical actuator 11 with one or more command units 12, 13, to reset one or more parameters, which can be for example the end position, to reset the movement of the paired one or more command units 12, 13 or control screen 2.

[0179] Here, the torque support 21 comprises a single selection device 41.

[0180] The number of selection devices of the torque support is not limiting and can be different. In particular, the number of selection devices of the torque support can be greater than or equal to 2.

[0181] The torque support 21 comprises at least one display device 42.

[0182] The display device or the display devices 42 are configured to display a visual indication, which can for example represent the operating mode of the electromechanical actuator 11, in particular the configuration mode or the control mode, or the state of the components of the electric drive means 5 or of the electric energy supply means 31, in particular the state of charge of the battery 24.

[0183] Advantageously, the display device 42 comprises at least one lighting source (not shown), in particular a light-emitting diode, mounted on the second electronic board 15b.

[0184] Here, the torque support 21 comprises a single display device 42.

[0185] The number of display devices is not limiting and can be different. In particular, the number of display devices can be greater than or equal to 2.

[0186] Advantageously, the selection device 41 and the display device 42 are electrically connected, i.e. configured to be electrically connected, to the electronic control unit 15.

[0187] Here, the selection device 41 and the display device 42 are electrically connected, i.e. configured to be electrically connected, to the second electronic control board 15b.

[0188] Advantageously, the selection device 41 and the display device 42 are mounted on the printed circuit board 40b.

[0189] In a variant, the selection device 41 and / or the display device 42 can be electrically connected, i.e. can be configured to be electrically connected, to the first electronic control board 15a.

[0190] The torque support 21 can comprise one or more selection means 41 or one or more display means 42, or it can comprise one or more selection means 41 and one or more display means 42.

[0191] In particular in the assembled configuration of the electromechanical actuator 11, the housing 44 at least accommodates, i.e. is configured to accommodate, one or more selection means 41 or one or more display means 42.

[0192] In this way, in particular in the assembled configuration of the electromechanical actuator 11, the housing 44 receives, i.e. is configured to receive, at least one of the selection means 41 or the display means 42.

[0193] Here, the torque support 21 comprises a single housing 44 in which the selection means 41 and the display means 42 are accommodated.

[0194] Advantageously, the electromechanical actuator 11 further comprises a cover 70 which is partially inserted into the housing 44 and which closes the housing 44, the cover surrounding the second electronic board 15b.

[0195] Here, the cover 70 comprises a button 72 which is configured to operate the selection means 41 when touched by a user.

[0196] Furthermore, the cover 70 comprises a light guide 74 which is configured to guide the light emitted by the display means 42 to the outside of the electromechanical actuator 11.

[0197] Here, the cover 70 is surrounded by the lid 22 so that the cover is covered by the lid. In particular, the lid covers and hides the joint line between the walls 21d, 21f of the housing 44 and the cover 70. Thus, in the assembled configuration of the electromechanical actuator 11, the cover 70 cannot be removed. The cover 70 can be removed from the housing 44 only when the lid 22 is removed, so that the second electronic board 15b is accessible.

[0198] In other words, the lid 22 protects the second electronic board 15b and the cover 70.

[0199] Advantageously, in a variant not shown, the cover 70 is configured to protect the second electronic board 15b from electrostatic discharges and possibly from water and humidity, by increasing the creep path travelled between the outside of the cover 70 and the second electronic board 15b due to electrostatic discharges, and the activation of the selection means 41 is done by movement of the cover itself or by deformation of a flexible portion of the cover at the detection means.

[0200] The absorption of the load applied to the structure of building B by the electromechanical actuator is ensured by the torque support 21. In fact, this absorption is achieved by preventing the torque support 21 from rotating relative to building B about the axis X21 of the torque support. In the assembly configuration of actuator 11, the axis X21 of the torque support coincides with the axis of rotation X.

[0201] In particular, in the assembly structure of the electromechanical actuator 11 in the shielding device 3, the rotation of the torque support 21 is locked by the cooperation of the torque support and the holding devices 9 and 23, thereby achieving the rotational locking of the fixing element (e.g., housing 17) of the electromechanical actuator 11.

[0202] In fact, the torque support 21 includes an opening 80 that extends parallel to the axis X21 from the wall 21d of the torque support 21 into the torque support 21.

[0203] Here, the opening 80 includes a central portion 80a and four arms 80b arranged perpendicularly to each other around the central portion 80a. Therefore, in this example, the opening 80 has a cross shape.

[0204] In the variations, opening 80 has different shapes, such as a pentagram, a triangle, or another polygon.

[0205] The opening 80 is configured to receive (i.e., receive) the retaining device 9, 23, and more particularly to receive (i.e. receive) the protruding part of the fixing support 23.

[0206] exist Figure 2 In the variant shown, where the fixing support 23 is not used and the winding tube 4 is held by the cheek plate 10 of the box 9, the opening 80 is configured to receive the protrusion of the attachment bracket attached to the cheek plate 10 of the box 9. For simplicity, in the remainder of the specification, this attachment bracket will be referred to as the fixing support 23.

[0207] As is well known, various shapes of fixed support parts 23 can be used to hold the winding tube 4 within the holding devices 9 and 23.

[0208] In order to avoid having to adapt the shape of the opening 80 to the shape of the fixed support 23 of the device 6 (which would mean that a large number of different types of torque support 21 would be needed to fit all shapes of fixed support 23), the torque support also includes a mounting plate 90.

[0209] The mounting plate 90 of the torque support 21 is fixed to the wall 21d of the torque support and has an opening 92. The opening 92 is aligned with the opening 80 of the torque support, and the shape of the opening 92 is adapted to the shape of the protruding part of the fixed support 23, that is, it is complementary to the shape of the fixed support 23.

[0210] In Figure 7 particular, the fixed support 23 is plate-shaped and its protruding portion 23a extends along an axis X23 perpendicular to the support, the cross-section of the protruding portion 23a being cruciform-shaped with four branches 23b defined between two surfaces 23c. The protruding portion 23a further comprises a central circular portion 23d from which the branches 23b extend.

[0211] In this case, the opening 92 of the mounting plate 90 comprises a central portion 92a and four arms 92b arranged perpendicular to each other around the central portion 92a. Thus, in this example, the opening 92 has a cruciform shape.

[0212] Furthermore, each arm 92b has two bearing surfaces 92c.

[0213] A "bearing surface" is defined as any surface of the opening 92 of the mounting plate 90 that generates a torque to rotate the torque support 21 when a force is applied to it, i.e. any surface that transmits a force to the surface on which it is supported when the torque support rotates, which force hinders the rotation of the torque support.

[0214] Thus, the opening 92 receives the protruding portion 23a of the fixed support 23 and the bearing surfaces 92c of the opening 92 are in contact with the surfaces 23c of the protruding portion 23a of the fixed support 23 with a tight operating clearance, so that the rotation of the torque support 21 is prevented in the mounting configuration of the electromechanical actuator 11 in the device 6.

[0215] Thus, the opening 80 of the torque support 21 has a generic shape, intended to be able to receive each portion protruding from a fixed support 23 of different shape, and the locking of the rotation of the torque support 21 is ensured by the opening 92 of the mounting plate 90, which is particularly adapted to the protruding portion 23a.

[0216] Furthermore, the profile of the opening 92 of the mounting plate 90 protruding in a plane perpendicular to the axis X21 is inscribed in the profile of the opening 80 of the torque support 21 protruding in the same plane. In other words, the plurality of openings 92 is compatible with the opening 80 of the torque support, so that the plurality of plates 90 is compatible with the torque support 21, making it possible for the force exerted by the electromechanical actuator 11 to be borne by cooperating with the protruding portion 23a of the fixed support 23.

[0217] Advantageously, the torque support 21 is prevented from rotating through the opening in the mounting plate 90 instead of directly through the opening 80 in the torque support, since the mounting plate 90 is inexpensive and easy to manufacture. This makes it easy to provide a plurality of mounting plates 90, each of which is adapted to a type of fixing support 23, more particularly to the geometry of the protruding portion 23a, thereby enabling a single torque support 21 to be adapted to a plurality of fixing supports 23.

[0218] Another advantage of the system is that it enables different materials to be used for the mounting plate 90 and the torque support 21. Indeed, since the mounting plate is subjected to greater forces resulting from the reaction of the fixing support 23 when the electromagnetic actuator 11 is operating than the torque support, it is preferable for the material of the mounting plate 90 to be very strong, in particular harder than the material of the torque support 21.

[0219] Here, the hardness is understood to be the mechanical resistance of the material to penetration.

[0220] For example, the mounting plate is made of a metallic material, for example stainless steel, which has good mechanical properties, i.e. resistance to wear, and the torque support is made of a polymeric material, preferably by molding, which enables complex shapes to be produced at low cost.

[0221] Advantageously, the mounting plate 90 is a single piece.

[0222] Indeed, the mounting plate 90 is obtained by machining a solid plate in which the mounting plate is cut out, then the opening 92 is cut out in this solid plate.

[0223] The mounting plate 90 then defines a substantially flat outer surface S90 and an inner surface S’90 which do not have a relief and which are parallel to each other.

[0224] The term “do not have a relief” means that the mounting plate 90 does not comprise any protrusions extending from the surfaces S90 and S’90.

[0225] In a variant, the mounting plate is made of a rigid polymeric material.

[0226] Furthermore, the mounting plate 90 is attached to the torque support 21 by means of fastening elements, for example screws, which are shown in the figures by their axis 95.

[0227] Indeed, the torque support 21 comprises holes 94 and the mounting plate 90 comprises holes 96 which are adapted to receive the screws 95.

[0228] Advantageously, and more particularly when the fastening elements are cone head screws, the holes 96 of the mounting plate each comprise a counterbore which is configured to house the head of the cone screw so that this head does not protrude from the mounting plate 90.

[0229] Here, the torque support 21 and the mounting plate 90 each comprise two holes 94, 96. In variants, the number of holes 94, 96 is different, for example there are three holes 94 and three holes 96.

[0230] Thus, attaching the mounting plate 90 to the torque support 21 and removing the mounting plate are particularly simple, since this is done using simple and quick fastening elements. Thus, for example, if during the installation of the electromechanical actuator 11 the user finds that the mounting plate 90 does not fit with the fixed support 23, it is easy to replace the mounting plate installed on the torque support 21.

[0231] As shown in Figures 5 to 7 the cover 22 is cylindrical, having a base 100 and a lateral surface 102.

[0232] In the assembled configuration of the electromechanical actuator 11, the lateral surface 102 is parallel to and in contact with the wall 21d of the torque support 21.

[0233] Here, the lateral surface 102 comprises an opening 104, which, when the cover 22 is installed on the torque support 21, is arranged opposite the selection device 41, so that the selection device 41 is accessible and activatable from the outside of the electromechanical actuator 11 through the opening 104.

[0234] In practice, the button 72 of the cap 70 extends through the opening 104, thus enabling the actuation of the selection device 41.

[0235] Similarly, the lateral surface 102 comprises an opening 106, which, when the cover 22 is installed on the torque support 21, is arranged opposite the display device 42, so that the visual indication emitted by the display device 22 is visible from the outside of the electromechanical actuator 11 through the opening 106.

[0236] In practice, the light guide 74 of the cap 70 extends through the opening 106, to transmit the visual indication emitted by the display 22 through the cover 22.

[0237] Thus, the openings 104 and 106 enable the connection of the second electronic board 15b to the outside of the electromechanical actuator 11, facing the electronic components carried by the second electronic board.

[0238] In practice, the number of openings 104, 106 of the cover 22 is adapted to the number of selection devices 41 and display devices 42 of the second electronic board 15b. For example, if the electronic board does not comprise a display device 42, the cover 22 does not comprise an opening 106.

[0239] The lateral surface 102 of the cover 22 comprises a cutout 110, in which the mounting plate 90 is installed.

[0240] Advantageously, the shape of the cutout 110 is complementary to the shape of the mounting plate 90. Thus, the cover 22 and the mounting plate 90 are complementary to hide the head 21e of the torque support 21.

[0241] Thus, in the assembled configuration of the electromechanical actuator 11, the mounting plate 90 does not protrude from the cover 22 and the outer surface S90 of the mounting plate is flush with the lateral surface 102.

[0242] By "flush", it is meant that the distance between the outer surface S90 of the mounting plate 90 and the lateral surface 102 of the cover 22 (measured along the rotation axis X) is less than 2 mm, preferably less than 1 mm.

[0243] The fact that the outer surface S90 of the mounting plate 90 is flush with the lateral surface 102 of the cover 22 is particularly advantageous because it minimizes the distance between the fixed support 23 and the electromechanical actuator 11, thus avoiding light leaks around the screen 2 when the latter is in the unfolded position, in particular when the device 6 does not comprise lateral runners 26. The electromechanical actuator 11 is also more aesthetic.

[0244] Advantageously, the lateral surface 102 of the cover 22 comprises a periphery 112, i.e. a rebate, arranged around the cutout 110. Indeed, the periphery 112 is an overhang which extends the lateral surface 102 towards the cutout 110 over a partial thickness of the lateral surface 102.

[0245] Furthermore, the mounting plate 90 is advantageously provided with a shoulder 114, the shoulder being provided along an outer edge 90a of the mounting plate, the edge 90a being opposite the wall 21d of the torque support 21.

[0246] Furthermore, the shoulder 114 and the periphery 112 are complementary in shape, so that in the assembled configuration of the electromechanical actuator 11, the shoulder rests on the periphery and a force parallel to the axis X21 and towards the housing 17 can be exerted on the periphery.

[0247] Thus, when the mounting plate 90 is attached to the wall 21d of the torque support 21, the cover 22 is held by the edge of the mounting plate, in contact with the shoulder.

[0248] Thus, the mounting plate 90 also holds the cover 22 assembled on the torque support 21.

[0249] In variants, the periphery 112 of the lateral surface 102 is provided only on a part of the cutout 110 and the shoulder 114 is provided only on a part of the outer edge 90a of the mounting plate 90. For example, the periphery 112 is formed in two parts on the cutout 110, each part having a length of between 5 and 20 mm, and the shoulder is formed in two parts on the edge 90a, each part having a length of between 5 and 20 mm.

[0250] In a variant, the mounting plate 90 does not comprise the shoulder 114. Thus, the outer edge 90a abuts against the periphery 112 of the cover 22 so as to retain the cover assembled on the torque support 21. Advantageously, in such an embodiment, the thickness of the mounting plate 90, measured along the axis X21, i.e. the distance between the surfaces S90 and S'90, is equal to or less than the thickness of the lateral surface 102 of the cover 22, measured along the axis X21, so that the outer surface S90 of the mounting plate is flush with the lateral surface 102. This maximizes the rigidity of the mounting plate.

[0251] Here, the cover 22 further comprises lugs 116 which are received in recesses 118 of the torque support 21 so that the cover 22 is snap-fitted onto the torque support 21.

[0252] Thus, the cover 22 is mounted on the torque support 21 by two steps: first, the cover 22 is snap-fitted with the lugs 116, then it is fixed with the mounting plate 90.

[0253] Moreover, the cover 22 is removed from the torque support by two steps: first, the mounting plate 90 is removed, then the lugs 116 are disengaged from the recesses 118, either with a tool (e.g. the tip of a flathead screwdriver) or by elastic deformation of the cover.

[0254] Such an assembly and disassembly have the particular advantage of being particularly simple, which makes it possible to easily replace the cover 22.

[0255] Thus, the cover 22 is easily replaceable, for example to change the color or the material according to the preferences of the user of the device 6.

[0256] In a variant, the cover 22 is retained on the torque support 21 only by latching. Advantageously, in such an embodiment, the mounting plate 90 does not comprise the shoulder 114 and the cover 22 does not comprise the periphery 112. Moreover, in such an embodiment, the cover 22 can be mounted and dismounted independently of the mounting plate 90, i.e. the cover can be mounted and dismounted whether the mounting plate is mounted or dismounted. Similarly, the mounting plate 90 can be mounted and dismounted independently of the cover 22. Thus, the cover 22 and the mounting plate 90 are independently interchangeable.

[0257] In summary, the electromechanical actuator 11 is particularly advantageous in that it is easily adaptable to the fixed support 23 whatever the type of the fixed support 23, and it is easily customizable thanks to the ease of interchanging the mounting plate 90 and the cover 22.

[0258] Moreover, the mounting plate 90 and / or the cover 22 can be replaced without dismounting or modifying the torque support 21 or breaking the electrical connections at the torque support. This is particularly advantageous because the torque support 21 is more complex and more risky to remove since there are electronic boards 15a and 15b attached to the torque support and since the connections, for example at the connector 19, must be broken when removing the torque support and can be sensitive.

[0259] Moreover, when the mounting plate 90 is removed from the torque support 21, only a portion of the wall 21 of the opening 80 is accessible from the outside of the electromechanical actuator 11. Thus, in this configuration, the delicate components of the electromechanical actuator, for example the electronic control unit 15, in particular the second electronic board 15b, and the connector 19, are not accessible. Thus, replacing the mounting plate 90 does not pose any risk of damaging the electromechanical actuator. This advantage is particularly apparent from the fact that since the mounting plate only covers a portion of the wall 21d of the torque support 21, the dimensions of the mounting plate 90 are smaller than the dimensions of the torque support 21. The same advantage exists when the cover 22 is removed since the electronic board 15b is held in the housing 44 closed by the hood 70 and the surface 21d of the housing limits access to the electronic board 15b when the cover 22 is removed.

[0260] Advantageously, the torque support 21 further comprises a bracket 120 extending from the wall 21d parallel to the axis X21.

[0261] In this example, the torque support 21 comprises two brackets 120.

[0262] The bracket 120 forms a member independent of the mounting plate 90 for holding the torque support 21 with respect to the fixed support 23 and preventing the torque support 21 from rotating about the axis X21. For example, the bracket 120 is configured to receive two attachment pins belonging to the fixed support 23 and extending parallel to the axis X23.

[0263] Thus, the torque support 21 offers two different mounting options for the fixed support 23.

[0264] Advantageously, the mounting plate 90 further comprises two recesses 122 the shape of which is complementary to the shape of the brackets 120. When the mounting plate 90 is attached to the torque support 21, the brackets 120 of the torque support are arranged in the recesses 122 so that the mounting plate 90 partially surrounds the brackets and the brackets 120 are flush with the outer surface S90 of the mounting plate, as shown in Figure 8 This enables the brackets 120 to remain free if necessary.

[0265] Reference will now be made to Figure 9Figs. 1 and 2 show two variants of the mounting plate 90, more specifically the differences between the mounting plate 90 shown in Figs. 1 and 2 and the mounting plate 90 shown in Figs. Figure 3 , Figure 6 , Figure 7 and Figure 8 .

[0266] The opening 92 of the mounting plate 90 of Fig. A) comprises four arms 92b arranged around a central portion 92a, the length of the arms being substantially the same as the mounting plate in Figs. Figure 6 and Figure 7 . The central portion 92a of the mounting plate of Fig. A) is larger compared to the central portion 92a of the mounting plates of Figs. Figure 6 and Figure 7 , i.e. the central portion of the mounting plate of Fig. A) can accommodate a protruding portion 23a with a circular central portion 23d of larger diameter, while the arms 92b are shorter.

[0267] The opening 92 of the mounting plate 90 of Fig. B) comprises only two arms 92b arranged around a central portion 92a and diametrically opposite. Furthermore, the arms of the mounting plate of Fig. B) are wider compared to the arms 92b of Fig. A), i.e. the distance between the two bearing surfaces 92c of each arm, measured perpendicular to these bearing surfaces, is larger. Thus, the opening 92 can accommodate a protruding portion 23a with thicker branches 23b. Similarly, the length of the arms 92b is larger than the length of the arms of Fig. A).

[0268] Many modifications can be made to the above-described embodiments without departing from the scope of the invention.

[0269] In variants, the protruding portion 23a of the support has a different geometry, for example a star-shaped cross-section, a cross-section with two or three branches or a polygonal cross-section. In this case, the geometry of the opening 92 is adapted. Thus, the opening 92 comprises a different number of arms 92b, for example two arms or three arms, or the opening has a different shape, for example a triangular shape. The opening of the mounting plate 92 must remain compatible with the opening 80 of the torque support in all cases, i.e. the shape of the opening 92 is adapted to the shape of the opening 80 of the torque support.

[0270] Regardless of the shape of the opening 92, the opening has at least one bearing surface 92c.

[0271] In a variant not shown, the opening 110 in the cover 22 is substantially equal to the circumference of the mounting plate 90, so that the mounting plate fits into the opening in the cover 22, while the torque support 21 is not visible between the cover and the mounting plate. In this embodiment, the mounting plate 90 does not comprise a shoulder, and the opening of the cover does not comprise a rim. The plate simply fits into the opening of the cover, both of which can be removed separately.

[0272] In a variant not shown, in particular in the assembled configuration of the screening device 3, the electromechanical actuator 11 is inserted in a track, in particular in a track having a square or rectangular cross section, which can be open at one or both ends. Moreover, the electromechanical actuator 11 can be configured to drive a drive shaft on which a rope for moving and / or orienting the screen 2 is wound.

[0273] Moreover, the expected embodiments and variants can be combined to form new embodiments of the application, without departing from the scope of the application.
