The present invention relates to an electromechanical actuator for a closing, shading or solar protection system, i.e. an electromechanical actuator of a closure, occultation or solar protection system, as well as a motorized driving device comprising such an actuator. The invention also relates to a closure, occultation or solar protection installation comprising a screen which is driven to move by such an electromechanical actuator or which includes such a motorized driving device.
In general, the present invention relates to the field of occultation devices comprising a motorized driving device moving a screen between at least one first position and at least one second position.
A motorized driving device generally comprises an electromechanical actuator of a movable closure, occultation, or solar protection element, such as a shutter, door, gate, blind, or any other equivalent equipment, hereinafter referred to as a screen.
Electromechanical actuators for closure, occultation or solar protection systems are already known, comprising a casing, a torque support, an electric power supply lead, an electric motor, an electronic control unit and a cover. The torque support is arranged at one end of the casing and collaborates with a holding device to take up 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 casing and is supplied with electrical energy by means of the power supply lead. The electronic control unit comprises at least one electronic board arranged inside the torque support. The cover is mounted on a torque support head.
When installing such electromechanical actuators, it is common to have to adapt the torque support to a support of the holding device. There is a wide variety of supports, with different shapes, with which the torque support must be compatible in order to be mounted.
It is common practice to add an adaptor to the torque support, allowing the connection between the torque support and the holding device's support, without having to adapt the shape of the torque support. Such an adapter is usually attached to one end of the torque support.
However, the disadvantage of these adapters is that they are inserted between the torque support and the holding device's support, which creates an extra thickness at the end of the electromechanical actuator. This extra thickness leads to a gap around the screen, between the screen and a lateral edge of an opening on which the closure, occultation or solar protection system is mounted, resulting in light leakage. Thus, the shading created by the screen is lower. Therefore, the addition of an adapter is not aesthetically pleasing and does not provide satisfactory shading.
The present invention aims to solve these drawbacks and to propose an electromechanical actuator, as well as a closure, occultation or solar protection installation comprising such an electromechanical actuator, which can be easily adapted to the support of a holding device without degrading the shading provided by a screen belonging to the installation.
In this respect, the present invention is directed, according to a first aspect, to an electromechanical actuator for driving a winding tube of a closure, occultation or solar protection installation, the electromechanical actuator comprising at least:
According to the invention, the electronic board is arranged inside a housing of the torque support, the cover closing the housing of the torque support. In addition, the torque support comprises a mounting plate, the mounting plate being fixed to one end of the torque support head by being mounted in a cutout in the lateral face of the cover. In addition, the mounting plate is provided with an opening configured to collaborate with a projecting part of a fixed support of a holding device to take up the load applied by the electromechanical actuator.
Owing 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 shading provided by the screen of an installation comprising such an electromechanical actuator.
According to advantageous but not mandatory aspects of the invention, the electromechanical actuator incorporates one or more of the following features, used in isolation or in any combination that is technically feasible:
According to a second aspect, the present invention relates to a occultation device for a closure, occultation or solar protection installation, comprising a winding tube, a screen that can be wound up on the winding tube, an electromechanical actuator driving the screen to move and a holding device including at least one fixed support, the electromechanical actuator being according to the invention and as mentioned above and the opening of the plate being shaped complementary to the shape of a projecting part of the fixed support and configured to receive this projecting part.
According to a third aspect, the present invention relates to a closure, occultation or solar protection installation comprising a screen that can be rolled up on a winding tube and driven to move by an electromechanical actuator, the electromechanical actuator being according to the invention and as mentioned above, or the installation comprising a occultation device according to the invention and as mentioned above.
This occultation device and this installation have similar features and advantages to those described above in relation to the electromechanical actuator according to the invention.

Thus, the limit stop 33 of the torque support 21 makes it possible to limit the depression of the first part 21a of the torque support 21 into the casing 17, along the direction of the axis of rotation X.
Furthermore, the limit stop 33 of the torque support 21 delimits the first and second parts 21a, 21b of the torque support 21 from each other.
Thus, only the first portion 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 limit stop 33, particularly in the assembled configuration of the electromechanical actuator 11, and the second portion 21b of the torque support 21 extends outside the casing 17.

The housing 44 is delimited, along the axis X, on the one hand by a wall 21d of the torque support 21, visible in
Advantageously, the first and second electronic boards 15a and 15b are connected to each other by connecting cables, not shown.

The number of selection devices of the torque support is not limiting and may be different. It may in particular be greater than or equal to two.
The torque support 21 comprises at least one display device 42.
This display device or these display devices 42 are configured to display a visual indication, which may be, for example, representative of an operating mode of the electromagnetic actuator 11, in particular a configuration mode or a control mode, or of a status of a member of the motorized driving device 5 or of the electrical energy supply device 31, in particular a charging status of the battery 24.
Advantageously, the display device 42 comprises at least one illumination source, not shown, in particular a light-emitting diode, mounted on a second electronic board 15b.
Here, the torque support 21 comprises a single display device 42.
The number of display devices is not limiting and may be different. It may in particular be greater than or equal to two.
Advantageously, the selection device 41 and the display device 42 are electrically connected, i.e. are configured to be electrically connected, to the electronic control unit 15.
Here, the selection device 41 and the display device 42 are electrically connected, i.e. are configured to be electrically connected, to the second electronic control board 15b.
Advantageously, the selection device 41 and the display device 42 are mounted on the printed circuit board 40b.
In a variant, the selection device 41 and/or the display device 42 may be electrically connected, i.e. may be configured to be electrically connected, to the first electronic control board 15a.
The torque support 21 may comprise either the selection device(s) 41 or the display device(s) 42, or the selection device(s) 41 and the display device(s) 42.
The housing 44 accommodates, i.e. is configured to accommodate, at least the selection device(s) 41 or display device(s) 42, in particular in the assembled configuration of the electromechanical actuator 11.
In this way, the housing 44 receives, i.e. is configured to receive, at least one of the selection device(s) 41 or display device(s) 42, in particular in the assembled configuration of the electromechanical actuator 11.
Here, the torque support 21 comprises a single housing 44, where the selection device 41 and the display device 42 are housed.
Advantageously, the electromechanical actuator 11 further comprises a hood 70, which is partially inserted in the housing 44 and closes this housing 44, the hood surrounding the second electronic board 15b.
Here, the hood 70 comprises a button 72, configured to operate the selection device 41 upon a user's touch.
In addition, the hood 70 comprises a light guide 74, configured to guide light emitted by the display device 42 to the exterior of the electromechanical actuator 11.
Here, the hood 70 is surrounded by the cover 22, so that it is covered by the cover. In particular, the cover covers and conceals the junction lines between the hood 70 and the walls 21d and 21f of the housing 44. Thus, in the assembled configuration of the electromechanical actuator 11, the hood 70 cannot be removed. When the cover 22 is removed, then the hood 70 can be removed from the housing 44, to make the second electronic board 15b accessible.
In other words, the cover 22 protects the second electronic board 15b and the hood 70.
Advantageously, in a variant not shown, the hood 70 is configured to protect the second electronic board 15b from electrostatic discharges, by increasing a creeping path travelled by an electrostatic discharge, between the outside of the hood 70 and the second electronic board 15b, and possibly to protect the second electronic board 15b from water and humidity. The cover then has a solid outer surface and the activation of the selection device 41 is done by movement of the hood itself or by deformation of a flexible part of the hood at the detection device.
The absorption of the loads applied by the electromechanical actuator on the structure of the building B, ensured by the torque support 21, is in practice achieved by preventing the rotation of the torque support 21, about an axis X21 of the torque support coinciding with the axis of rotation X in the assembled configuration of the actuator 11, with respect to the building B.
This locking of the rotation of the torque support 21, and thus of the rotation of the fixed elements of the electromechanical actuator 11, such as the casing 17, is achieved by the collaboration of the torque support with the holding device 9, 23, in particular in an assembled configuration of the electromechanical actuator 11 in the occultation device 3.
In practice the torque support 21 comprises an opening 80, which extends into the torque support 21 from the torque support wall 21d, parallel to the axis X21.
Here, the opening 80 comprises a central portion 80a and four arms 80b, arranged perpendicular to each other around the central portion 80a. Thus, in the example, the opening 80 has the shape of a cross.
In a variant, the opening 80 has a different shape, for example a five-pointed star shape, a triangular shape or another polygonal shape.
The opening 80 is configured to receive, i.e. receives, a part of the holding device 9, 23, and more particularly a projecting part of a fixed support 23.
In the variant illustrated in
It is known that a wide variety of fixed supports 23 with different shapes can be used within the holding device 9, 23 to hold the winding tube 4.
To avoid having to adapt the shape of the opening 80 to the shape of the fixed support 23 of the installation 6, which would imply a large variety of models of torque supports 21 that could fit all shapes of fixed supports 23, the torque support further comprises a mounting plate 90.
The mounting plate 90 of the torque support 21 is fixed to the wall 21d of the torque support and is provided with an opening 92, which is aligned with the opening 80 of the torque support and the shape of which is adapted to that of the projecting part of the fixed support 23, i.e. complementary to the shape of the fixed support 23.
In
Here, the opening 92 of the mounting plate 90 comprises a central part 92a and four arms 92b, arranged perpendicular to each other around the central part 92a. Thus, in the example, the opening 92 has the shape of a cross.
In addition, each arm 92b has two bearing surfaces 92c.
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 a surface bearing against it when the torque support rotates, which force opposes the rotation of the torque support.
Thus, the opening 92 receives the projecting part 23a of the fixed support 23 and the bearing surfaces 92c of the opening 92 are in contact with the surfaces 23c of the projecting part 23a of the fixed support 23, at close operating clearance, so that rotation of the torque support 21 about the axis X21 is prevented in the mounted configuration of the electromechanical actuator 11 in the installation 6.
Thus, the opening 80 of the torque support 21 has a generic shape, intended to be able to receive various parts projecting from the fixed support 23 of different shapes, and the locking of the rotation of the torque support 21 is ensured by the opening 92 of the mounting plate 90, which is specifically adapted to the projecting part 23a.
Furthermore, the outline of the opening 92 of the mounting plate 90, projected in a plane perpendicular to the axis X21, is inscribed in the outline of the opening 80 of the torque support 21, projected in the same plane. In other words, a plurality of openings 92 are compatible with the opening 80 of the torque support, so that a plurality of plates 90 are compatible with the torque support 21 and thus enable the forces exerted by the electromechanical actuator 11 to be taken up by collaboration with the projecting part 23a of the fixed support 23.
It is advantageous to provide that the torque support 21 is prevented from rotating through the opening in the mounting plate 90 rather than directly through the opening 80 in the torque support, as the mounting plate 90 is inexpensive and easier to manufacture. This makes it easy to provide a wide variety of mounting plates 90, each adapted to a type of fixed support 23, more particularly to a geometry of the projecting part 23a, thus allowing a single torque support 21 to be adapted to a wide variety of fixed supports 23.
Another advantage of this system is that it allows a different material to be used for the mounting plate 90 and for the torque support 21. Indeed, as the mounting plate is subject to greater forces than the torque support, generated by the reaction of the fixed support 23 when the electromagnetic actuator 11 is in operation, it is preferable that the material of the mounting plate 90 is very strong, in particular harder than the material of the torque support 21.
Here, hardness is understood to be the mechanical resistance of a material against penetration.
For example, the mounting plate is made of a metallic material, e.g. stainless steel, which has good mechanical properties, i.e. is wear-resistant, and the torque support is made of a polymeric material, preferably by moulding, which makes it possible to produce a complex shape at low cost.
Advantageously, the mounting plate 90 is a single piece.
In practice, the mounting plate 90 is obtained by machining a solid plate, into which the mounting plate is cut, and then into which the opening 92 is cut.
The mounting plate 90 then defines an outer surface S90 and an inner surface S′90, which are substantially flat, have no relief and are parallel to each other.
The term “have no relief” means that the mounting plate 90 does not comprise any protrusions extending from the faces S90 and S′90.
In a variant, the mounting plate is made of a rigid polymer material.
In addition, the mounting plate 90 is attached to the torque support 21 by means of fastening elements, such as screws, illustrated in the figures by their axis lines 95.
In practice, the torque support 21 comprises holes 94 and the mounting plate 90 comprises holes 96, the holes 94 and 96 being adapted to receive the screws 95.
Advantageously, and more particularly when the fastening elements are tapered head screws, the holes 96 of the mounting plate each comprise a countersink, configured to accommodate the head of a tapered screw, such that this head does not protrude from the mounting plate 90.
Here, the torque support 21 and the mounting plate 90 each comprise two holes 94, 96. In a variant, the number of holes 94, 96 is different, for example three holes 94 and three holes 96.
Attaching and removing the mounting plate 90 to the torque support 21 is therefore particularly simple, as it is done using simple and quick fastening elements. Thus, it is easy to change the mounting plate installed on the torque support 21, for example if, during the installation of the electromechanical actuator 11, the user finds that the mounting plate 90 does not fit the fixed support 23.
As can be seen in
In the assembled configuration of the electromechanical actuator 11, the lateral face 102 is parallel to, and in contact with, the wall 21d of the torque support 21.
Here, the lateral face 102 comprises an opening 104 arranged opposite the selection device 41 when the cover 22 is mounted on the torque support 21, so that the selection device 41 is accessible and activatable through the opening 104, from outside the electromechanical actuator 11.
In practice, the button 72 of the hood 70 extends through the opening 104 to allow actuation of the selection device 41.
Similarly, the lateral face 102 comprises an opening 106 arranged opposite the display device 42 when the cover 22 is mounted on the torque support 21, so that a visual indication emitted by the display device 22 is visible through the opening 106 from outside the electromechanical actuator 11.
In practice, the light guide 74 of the hood 70 extends through the opening 106 to transmit the visual indication emitted by the display 22 through the cover 22.
Thus, the openings 104 and 106 allow the second electronic board 15b to be connected to the exterior of the electromechanical actuator 11, facing the electronic components carried by the second electronic board.
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, then the cover 22 does not comprise an opening 106.
The lateral face 102 of the cover 22 comprises a cutout 110, in which the mounting plate 90 is mounted.
Advantageously, the shape of the cutout 110 is complementary to the shape of the mounting plate 90. The cover 22 and the mounting plate 90 are therefore complementary to conceal the head 21e of the torque support 21.
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 face 102.
“Flush” means that the distance between the outer surface S90 of the mounting plate 90 and the lateral face 102 of the cover 22, measured along the axis of rotation X, is less than 2 mm, preferably less than 1 mm.
The fact that the outer surface S90 of the mounting plate 90 is flush with the lateral face 102 of the cover 22 is particularly advantageous, as it minimises the distance between the fixed support 23 and the electromechanical actuator 11, thus avoiding light leakage around the screen 2, when the screen 2 is in the unrolled position, particularly when the installation 6 does not comprise lateral slides 26. The electromechanical actuator 11 is also more aesthetically pleasing.
Advantageously, the lateral face 102 of the cover 22 comprises a rim 112, i.e. a rabbet, arranged around the cutout 110. In practice, the rim 112 is an overhang that extends the lateral face 102 towards the cutout 110 over part of the thickness of the lateral face 102.
Furthermore, the mounting plate 90 is advantageously provided with a shoulder 114, provided along an outer edge 90a of the mounting plate, the edge 90a being directed towards the wall 21d of the torque support 21.
Furthermore, the shoulder 114 and the rim 112 are complementary in shape, so that in the assembled configuration of the electromechanical actuator 11, the shoulder rests on the rim and can exert on it a force parallel to the axis X21 and directed towards the casing 17.
Thus, when the mounting plate 90 is attached to the wall 21d of the torque support 21, the cover 22 is retained by the mounting plate by its edge, in contact against the shoulder.
The mounting plate 90 therefore also holds the cover 22 assembled on the torque support 21.
In a variant, the rim 112 of the lateral face 102 is provided on only part of the cutout 110 and the shoulder 114 is provided on only part of the outer edge 90a of the mounting plate 90. For example, the rim 112 is formed on the cutout 110 in two portions, each portion being between five and twenty millimetres in length, and the shoulder is formed on the edge 90a in two portions, each portion being between five and twenty millimetres in length.
In a variant, the mounting plate 90 does not comprise a shoulder 114. The outer edge 90a then rests against the rim 112 of the cover 22, so as to hold 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 smaller than the thickness of the lateral face 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 face 102. This maximises the rigidity of the mounting plate.
Here, the cover 22 also comprises lugs 116, which are received in recesses 118 of the torque support 21, so that the cover 22 is snapped onto the torque support 21.
Thus, the cover 22 is mounted on the torque support 21 in two steps: first it is snapped on with the lugs 116 and then secured with the mounting plate 90.
In addition, the cover 22 is removed from the torque support in two steps: first the mounting plate 90 is removed and then the lugs 116 are moved away from the recesses 118, either with a tool, such as the tip of a flathead screwdriver, or by resilient deformation of the cover.
This assembly and disassembly has the advantage of being particularly simple, which allows the cover 22 to be easily replaced.
Thus, the cover 22 is easily changed, for example to change the colour or material, according to the preferences of a user of the installation 6.
In a variant, the cover 22 is only held by latching onto the torque support 21. Advantageously, in such an embodiment the mounting plate 90 does not comprise a shoulder 114 and the cover 22 does not comprise a rim 112. Furthermore, 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.
In summary, the electromechanical actuator 11 is particularly advantageous because it is simple to adapt to a fixed support 23, regardless of the type of fixed support 23, and it is simple to customise, thanks to the mounting plate 90 and the cover 22, which are easily interchangeable.
In addition, the mounting plate 90 and/or the cover 22 can be changed without disassembling or modifying the torque support 21 or disconnecting the electrical connections at the torque support. This is particularly advantageous as the torque support 21 is more complex and risky to remove, due to the presence of the electronic boards 15a and 15b attached to it and due to the connections, for example at the connector 19, which must be disconnected when removing the torque support and which may be sensitive.
Furthermore, 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 outside the electromechanical actuator 11. Thus, in this configuration, no fragile parts of the electromechanical actuator, such as for example the electronic control unit 15 and especially the second electronic board 15b and the connector 19, are accessible. Changing the mounting plate 90 thus does not pose any risk of damaging the electromechanical actuator. This advantage is particularly apparent from the fact that the dimensions of the mounting plate 90 are small compared to the size of the torque support 21, as the plate only covers part of the wall 21d of the torque support 21. The same advantage is present when the cover 22 is removed, due to the fact that the electronic board 15b is kept in the housing 44, closed by the hood 70, and the face 21d of the housing limits access to the electronic board 15b when the cover 22 is removed.
Advantageously, the torque support 21 also comprises brackets 120, which extend from the wall 21d parallel to the axis X21.
In the example, the torque support 21 comprises two brackets 120.
The brackets 120 form members, independent of the mounting plate 90, for holding the torque support 21 relative to the fixed support 23 and preventing rotation of the torque support 21 about the axis X21. For example, the brackets 120 are configured to receive two attachment pins belonging to the fixed support 23 and extending parallel to the axis X23.
Thus, the torque support 21 offers two different mounting options for the fixed support 23.
Advantageously, the mounting plate 90 also comprises two indentations 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 indentations 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 best seen in
Two variants of the mounting plate 90 are now described with reference to the inserts A) and B) in
The opening 92 of the mounting plate 90 of insert A) comprises four arms 92b arranged around the central portion 92a, of substantially the same length as the mounting plate in
The opening 92 of the mounting plate 90 of the insert B) comprises only two arms 92b arranged around the central portion 92a and diametrically opposed. Furthermore, compared to the arms 92b of insert A), the arms of the mounting plate of insert B) are wider, i.e. the distance between the two bearing surfaces 92c of each arm, measured perpendicularly to these bearing surfaces, is greater. Thus, the opening 92 can accommodate a projecting part 23a with thicker branches 23b. Similarly, the lengths of the arms 92b are greater than the lengths of the arms of the insert A)
Numerous modifications can be made to the above-described embodiments without departing from the scope of the invention.
In a variant, the projecting part 23a of the support has a different geometry, for example with 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. The opening 92 then comprises a different number of arms 92b, for example two arms or three arms, or a different shape, such as a triangular shape. The opening of the mounting plate 92 must in all cases remain compatible with the opening 80 of the torque support, i.e. the shape of the opening 92 fits into the shape of the opening 80 of the torque support.
Regardless of the shape of the opening 92, the opening has at least one supporting surface 92c.
In a variant, not shown, the opening 110 in the cover 22 is substantially equal to the perimeter of the mounting plate 90, so that the mounting plate fits into the opening in the cover 22 without the torque support 21 being visible between the cover and the mounting plate. In this embodiment, the mounting plate 90 does not comprise a shoulder and the cover opening does not comprise a rim. The plate simply fits into the opening of the cover and both can be removed separately.
In a variant, not shown, the electromechanical actuator 11 is inserted in a rail, in particular of square or rectangular cross-section, which can be opened at one or both ends, particularly in the assembled configuration of the occultation device 3. In addition, the electromechanical actuator 11 may be configured to drive a drive shaft on which cords for moving and/or orienting the screen 2 are wound.
Furthermore, the contemplated embodiments and variants may be combined to form new embodiments of the invention, without departing from the scope of the invention.
