Technical Field

The present invention relates to a vibrating filter mechanical assembly for mounting at least partially within the housing of an electromechanical actuator for a closure, covering or sun shading device.

The invention also relates to an electromechanical actuator with such a vibration filter mechanism assembly and to a closing, covering or shading device with a screen windable on a roller tube driven in rotation by such an electromechanical actuator.

The present invention relates generally to the field of screening devices having an electric drive which moves a screen between at least one first position and at least one second position.

Background

The electric drive has an electromechanical actuator for a moving part for closing, covering or shading, such as a blind, a door, a fence, a blind or any other equivalent, hereinafter referred to as screen.

An electromechanical actuator is mounted within the spool. In addition, the electromechanical actuator has at least an electric motor and preferably also a reduction gear. When the electromechanical actuator is operated, the motor and the reducer generate vibrations, which may be transmitted to elements surrounding the motor, particularly the housing and the roller tube of the electromechanical actuator.

Therefore, in an assembly configuration in which the electromechanical actuator is assembled in the apparatus, the electromechanical actuator generates noise when the electromechanical actuator is operated.

The known document WO2018/104488a1 proposes a vibrating filtering mechanical assembly for mounting inside the casing of an electromechanical actuator for a closing, covering or sun-shading device. The vibratory filter mechanism assembly has a vibratory filter mechanism member. The vibration filtering mechanical member is monolithic, extending along a longitudinal axis intended to be aligned with the rotation axis of the rotor of the electric machine. The vibrating filtering mechanical member has a first end portion and a middle portion. The first end portion has a first loop. The intermediate portion is connected to the first end portion. The first diameter of the first loop of the first end portion is greater than a maximum dimension of the middle portion measured in a plane orthogonal to the longitudinal axis.

However, this vibrating filter machine assembly has the drawback of making the manufacture of the vibrating filter machine component difficult. This is even more difficult if the electromechanical actuator housing has a small inner diameter.

Therefore, the size of the vibrating filter mechanical member, the thickness of the attachment of the intermediate portion and the complexity of the attachment of the intermediate portion thereof lead to a complexity of industrial production, which is manifested by high costs and is prone to quality problems.

In addition, the industrial production of the vibrating filtering mechanical member is difficult when the plastic material constituting said member is injection-molded, in particular when it is made to flex along its length.

In addition, this structure of the vibration filtering mechanical member has a long length.

Therefore, the vibration filtering mechanical member occupies a large size in the housing of the electromechanical actuator, and thus the length of the electromechanical actuator is long.

In addition, the vibration filtering mechanical member is configured to be fixed to the housing of the electromechanical actuator on the one hand and to the motor on the other hand.

The screen 2 of the shading device 3 is wound around a roller tube 4 driven by an electric drive 5. The screen is thus movable between a rolled position, in particular an upper rolled position, and an unfolded position, in particular a lower unfolded position.

The screen 2 of the screening arrangement 3 is a screen for closing, covering and/or shading, which is rolled and unrolled around the roller tube 4, the inner diameter of the roller tube 4 being significantly larger than the outer diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the roller tube 4 when the screening arrangement 3 is assembled.

The torque support 21 of the electromechanical actuator 11 thus enables the electromechanical actuator 11 to be fixed to the retaining means 9, 23, in particular to one of the supports 23 or to one of the side panels 10 of the cabinet 9.

Advantageously, the torque support 21 protrudes at the first end 17a of the housing 17 of the electromechanical actuator 11, in particular at the end 17a of the housing 17 that receives the crown. In the assembled configuration of the screening device 3 the annular crown is constituted, in other words configured, to form a bearing for guiding the rotation of the roller tube 4.

Here, the moment support 21 has a single button.

The number of buttons of the torque support is not limiting and may vary. In particular, the number of buttons may be more than two or equal to two.

Advantageously, the torque support 21 has at least one lighting device (not shown) in order to allow a visual indication, which may be for example the state of charge of the battery 24.

Advantageously, the lighting device has at least one lighting source (not shown), in particular a photodiode, which is mounted on the second circuit board 15b, and if necessary also a transparent or translucent cover and/or a light guide for allowing the light emitted by the lighting source to pass.

The number of lighting devices is not limiting and may vary. In particular, the number of lighting devices may be greater than or equal to two.

Advantageously, the output shaft 20 of the electromechanical actuator 11 is arranged inside the roller tube 4, at least partially outside the housing 17 of the electromechanical actuator 11.

Here, one end of the output shaft 20 protrudes with respect to the housing 17 of the electromechanical actuator 11, in particular with respect to a second end 17b of the housing 17 opposite to the first end 17 a.

Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive in rotation a coupling (not shown) connected to the roller tube 4. The connecting element is embodied in the form of a wheel.

In operating the electromechanical actuator 11, the motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11 drives the roller tube 4 in rotation via a coupling.

The roller tube 4 thus rotates the screen 2 of the screening device 3 to open or close the opening 1.

The electromechanical actuator 11 has a vibration filtering mechanical assembly 33. In addition, a vibration filtering mechanical assembly 33 is mounted at least partially within the housing 17 of the electromechanical actuator 11.

Referring now to fig. 4 to 10, the vibration filtering mechanical assembly 33 of the electromechanical actuator 11 according to the first embodiment of the present invention shown in fig. 3 is illustrated.

The vibrating filter mechanism assembly 33 has at least one vibrating filter mechanism member 34. The vibrating filtering mechanical member 34 is monolithic, extending along a longitudinal axis X34, said longitudinal axis X34 being intended to be aligned with the rotation axis X of the rotor 31 of the electric machine 16.

The vibrating filtering mechanical member 34 has at least a first end portion 35 and a middle portion 36. The first end portion 35 has a first loop 37. In addition, the intermediate portion 36 is connected to the first end portion 35. The first diameter D37 of the first loop 37 of the first end portion 35 is greater than the maximum dimension H36 of the intermediate portion 36 measured in a plane P orthogonal to the longitudinal axis X34.

The first end portion 35 also has a plurality of first arms 38. Each first arm 38 connects the intermediate portion 36 to the first ring 37.

This structure of the vibration filter mechanical member 34 is therefore simplified, ensuring a reduction in the transmission of vibrations from the electromechanical actuator 11 to the device 6, while minimizing the manufacturing costs of the vibration filter mechanical assembly 33 and therefore of the electromechanical actuator 11, in particular with respect to the known prior art of document WO2018/104488a 1.

Thus, the vibration filter mechanism assembly 33 can be easily industrially produced.

The structure of the vibration filtering mechanical member 34 allows the deformation of the intermediate portion 36 to occur, thus allowing the torsion of the joint between the intermediate portion 36 and the first end portion 35 to occur.

The structure of the vibration filter mechanism member 34 also allows to minimize the member length L34, thus allowing to obtain a vibration filter mechanism assembly 34 that is compact, so as to minimize the length L11 of the electromechanical actuator 11.

Advantageously, the length L34 of the vibration filtering mechanical member 34 is determined to optimize the absorption of vibrations.

In addition, the first arm 38 of the first end portion 35 may ensure a high torsional stiffness and a low bending stiffness of the vibrating filtering mechanical member 34 around the rotation axis X.

In addition, such a vibration filter mechanical assembly 33 is particularly suitable for electromechanical actuators having a housing with a small diameter D17e, in particular a small outer diameter, and the diameter D17e may be, for example, about 20 mm to 60 mm, preferably about 25 mm to 30 mm.

The maximum dimension H36 of the intermediate portion 36, measured in a plane P orthogonal to the longitudinal axis X34, corresponds to the height.

Here, the vibration filter mechanism assembly 33 has a single vibration filter mechanism member 34.

The use of a single vibration filtering mechanical member 34 is a result of the weight of the electromechanical actuator 11, in particular due to the integration of the battery 24 within the housing 17.

In this first embodiment, the intermediate portion 36 has a circular cross-section in a plane P orthogonal to the longitudinal axis X34.

Thus, the height H36 of the intermediate portion 36 in a plane P orthogonal to the longitudinal axis X34 corresponds to the diameter D36 of the intermediate portion 36.

Advantageously, the vibrating filtering mechanical member 34 also has at least a second end portion 39. The second end portion 39 is opposite the first end portion 35 along the longitudinal axis X34. The second end portion 39 has a second ring 40. The intermediate portion 36 is connected to the second end portion 39, arranged between the first and second end portions 35, 39. The second diameter D40 of the second ring 40 of the second end portion 39 is greater than the largest dimension H36 of the intermediate portion 36 measured in a plane P orthogonal to the longitudinal axis X34. In addition, the second end portion 39 also has a plurality of second arms 41. Each second arm 41 connects the intermediate portion 36 to the second ring 40.

Thus, the structure of the vibration filtering mechanical member 34 also allows for torsion to be generated at the junction between the intermediate portion 36 and the second end portion 39.

In addition, the second arm 41 of the second end portion 39 can ensure high torsional rigidity and low bending rigidity of the vibration filtering mechanical member 34.

The intermediate portion 36 may also be referred to herein as a center beam. The first end portion 35 may also be referred to as a first mounting end plate. The second end portion 39 may also be referred to as a second mounting end plate. The first loop 37 of the first end portion 35 may also be referred to as a first rim. Additionally, the second ring 40 of the second end portion 39 may also be referred to as a second bead.

Advantageously, the second end portion 39 of the vibrating filtering mechanical member 34 has a second cavity 57. In addition, in the assembled configuration of electromechanical actuator 11, second cavity 57 of second end portion 39 is mated to torque support member 21, in particular to shaft 58 of torque support member 21, in other words second cavity 57 is configured to mate to torque support member 21, in particular to shaft 58 of torque support member 21.

Thus, in the assembled configuration of the electromechanical actuator 11, the shaft 58 of the torque support 21 is housed inside the second cavity 57 of the second end portion 39 of the vibrating filtering mechanical member 34.

In this way, in the assembled configuration of the electromechanical actuator 11, the second end portion 39 of the vibrating filtering mechanical member 34 is retained to the torque support 21 by the fitting.

Advantageously, the second end portion 39 of the vibrating filtering mechanical member 34 has at least one second protuberance element 59 extending from the inner surface 40a of the second ring 40 in the direction of the longitudinal axis X34, in other words in the second cavity 57 of the second end portion 39. The shaft 58 of the torque support 21 has at least one recess element 60. In addition, in the assembled configuration of electromechanical actuator 11, said second protruding element 59 of second end portion 39 of vibration filtering mechanical member 34 cooperates with said recessed element 60 of shaft 58 of torque support 21, in other words said second protruding element 59 is configured to cooperate with said recessed element 60.

Said second elevation elements 59 of the second end portion 39 may also be referred to as ribs or teeth.

Here, the second end portion 39 of the vibrating filtering mechanical member 34 has three second protuberance elements 59 arranged around the rotation axis X and the longitudinal axis X34 at an angle of 120 ° with respect to each other. In addition, the shaft 58 of the torque support 21 has three recess elements 60, which are arranged at an angle of 120 ° relative to one another about the axis of rotation X.

Thus, in the assembled configuration of electromechanical actuator 11, second end portion 39 of vibration filtering mechanical member 34 is engaged with torque support 21. The cooperation of said second protuberance element 59 of the second end portion 39 of the vibrating filtering mechanical member 34 with said recess element 60 of the shaft 58 of the torque support 21 allows the second cavity 57 of the second end portion 39 of the vibrating filtering mechanical member 34 to engage on the shaft 58 of the torque support 21 by means of the axial sliding D, while ensuring the prevention of the rotation between the second end portion 39 of the vibrating filtering mechanical member 34 and the torque support 21.

Therefore, the vibration filtering mechanical member 34 is fitted on the first end portion 17a side of the housing 17 of the electromechanical actuator 11 at which the torque support 21 is fitted.

Here, the first fixing piece 44 and the second fixing piece 45 are fixing screws.

Advantageously, the first arm 38 of the first end portion 35 is angularly offset by a predetermined angle α about the longitudinal axis X34 with respect to the second arm 40 of the second end portion 39, as shown in fig. 8.

The angular offset of the first arm 38 with respect to the second arm 40 about the longitudinal axis X34 therefore allows to ensure symmetry regardless of the mounting angular position of the vibrating filtering mechanical member 34 with respect to the casing 17, in this case with respect to the torque support 21.

In this way, the angular offset of the first arm 38 with respect to the second arm 40 about the longitudinal axis X34 allows to ensure symmetry of the force with respect to the housing 17, in this case with respect to the torque support 21, when the electromechanical actuator 11 drives the roller tube 4 in rotation.

In this way, the flexible portion 63e may fit within the rigid bracket 63d and/or around the rigid bracket 63 d.

In this way, the bushing 63 has a limited axial clearance J in the direction of the rotation axis X between the torque support 21, in particular the shaft 58 of the torque support 21, and the vibrating filtering mechanical member 34.

Therefore, such fitting of the bushing 63 within the housing 17 of the electromechanical actuator 11 can limit the axial deformation of the vibration filtering mechanical member 34.

Thus, in the assembled configuration of the electromechanical actuator 11, the bushing 63 is oriented about the rotation axis X with respect to the housing 17 of the electromechanical actuator 11.

Here, the positioning element 67 of the bushing 63 is a stud or a rib.

Here, the second end portion 39 of the vibration filter mechanical member 34 forms the torque support 21.

Thus, in case the second end portion 39 of the vibration filter mechanical member 34 forms the torque support 21, the length L11 of the electromechanical actuator 11 may be shortened, since the torque support 21 is integrated to the vibration filter mechanical member 34.

Advantageously, the first diameter D37 of the first ring 37 is less than or equal to the second diameter D40 of the second ring 40.

Preferably, in case the second end portion 39 of the vibrating filtering mechanical member 34 forms the torque support 21, the diameter D40 of the second ring 40 of the second end portion 39 is larger than or equal to the inner diameter D17i of the housing 17.

Here, the vibration filter mechanical assembly 33, in particular the first part of the vibration filter mechanical member 34, formed by the intermediate portion 36 and the first end portion 35, is mounted within the housing 17 of the electromechanical actuator 11. In addition, the vibration filter mechanical assembly 33, in particular the second part of the vibration filter mechanical member 34, formed by the second end portion 39, is mounted outside the housing 17 of the electromechanical actuator 11.

Referring now to fig. 12 and 13, a vibration filtering mechanical assembly 33 of the electromechanical actuator 11 shown in fig. 3 according to a third embodiment of the present invention is illustrated.

Here, the intermediate portion 36 has a rectangular cross-section in a plane P orthogonal to the longitudinal axis X34.

Therefore, a rectangular cross section of the intermediate portion 36 in a plane P orthogonal to the longitudinal axis X34 is particularly suitable in the case where the electromechanical actuator 11 can only be mounted in a single position in the apparatus 6, in particular with respect to the holding means 9, 23.

Thus, in a plane P orthogonal to the longitudinal axis X34, the height H36 of the intermediate portion 36 is less than its width W36.

Advantageously, the width W36 of the intermediate portion 36 is orthogonal to the wall M of the building B shown in fig. 1. In the assembled configuration, in which the electromechanical actuator 11 is assembled in the device 6, the wall M of the building B is parallel to the direction in which the screen 2 is wound and unwound around the roller tube 4. In addition, the height H36 of the intermediate portion 36 is parallel to this wall M of the building B or to the gravitational field direction.

In this case, therefore, the vibrating filtering mechanical member 34 can have a low flexural rigidity in the decisive vibration transmission direction, in particular in the direction orthogonal to the wall M, while maintaining a high flexural rigidity as well as a high torsional rigidity in the direction of gravity.

Here, the first end portion 35 has four first arms 38. In addition, the second end portion 39 has four second arms 41.

In addition, the angular offset of the first arm 38 with respect to the second arm 40 about the longitudinal axis X34 has a predetermined angular value α of about 45 °.

Here, the first end portion 35 has four first interspaces 48 between the first ring 37 and the four first arms 38 for the passage of one or more cables 18, 50, 52. Each first void 48 corresponds to an opening formed between two adjacent first arms 38 and the first ring 37.

In addition, the second end portion 39 has four second interstices 49 between the second ring 40 and the four second arms 41 for the passage of one or more cables 18, 50, 52. Each second void 49 corresponds to an opening formed between two adjacent second arms 41 and second ring 40.

Referring now to fig. 1 to 13, there are illustrated aspects of a vibration filtering mechanical assembly 33 suitable for use in the electromechanical actuator 11 of fig. 3 of the first, second and third embodiments of the present invention described above.

The dimensions of the vibrating filtering mechanical member 34 are determined according to the requirements required, in particular in terms of mechanical strength, deformation and rigidity. The size of the vibrating filtering mechanical member 34 is determined according to its material selection.

The dimensions of the vibrating filtering mechanical member 34 to be determined according to the above parameters, in particular the height H36 and the width W36 or the diameter D36 of the intermediate portion 36 in a plane P orthogonal to the longitudinal axis X34, the length L36 of the intermediate portion 36, the lengths L38, L41 of the first arm 38 and optionally of the second arm 41 between the intermediate portion 36 and the first ring 37 or the second ring 40, respectively, the thicknesses e38, e41 of the first arm 38 and optionally of the second arm 41, and optionally the dimensions of the notches 55, 56 provided in the first and second arms 38, 41 and in the intermediate portion 36.

In order to reduce the bending stiffness of the vibrating filtering mechanical member 34, the dimensions of the vibrating filtering mechanical member are changed in such a way as to implement at least one of the following possibilities: lengthening the length L36 of the intermediate portion 36, lengthening the lengths L38, L41 of the first arm 38 and optionally of the second arm 41, in other words reducing the height H36 of the intermediate portion 36 in a plane P orthogonal to the longitudinal axis X34 or the diameter D36 of the intermediate portion 36, or reducing the thicknesses e38, e41 of the first arm 38 and optionally of the second arm 41.

In order to increase the mechanical strength and reduce the deformation of the vibrating filtering mechanical member 34, the dimensions of the vibrating filtering mechanical member are changed in such a way as to implement at least one of the following possibilities: : shortening the length L36 of the intermediate portion 36, shortening the lengths L38, L41 of the first arm 38 and optionally the second arm 41, in other words increasing the height H36 of the intermediate portion 36 in a plane P orthogonal to the longitudinal axis X34 or the diameter D36 of the intermediate portion 36, or increasing the thicknesses e38, e41 of the first arm 38 and optionally the second arm 41.

Another parameter to consider for the dimensioning of the vibrating filter mechanism component 34 is the weight of the component suspended by the vibrating filter mechanism component 33.

The dimensioning of the vibrating filter mechanism member 34 is carried out to ensure its shear strength, according to the weight of the component to be suspended by the vibrating filter mechanism assembly 33.

In a first embodiment, the component to be suspended by means of the vibrating filtering mechanical assembly 33 is an electromechanical actuator 11, in which the battery 24 can be integrated.

In a second embodiment, the components to be suspended by means of the vibrating filter mechanism assembly 33 are the sheltering device 3, i.e. the roller tube 4, the screen 2 and the electromechanical actuator 11, which may have a battery 24 integrated therein.

In this case, the vibration filtering mechanical member 34 has high bending rigidity and high torsional rigidity, and its structure is compact.

The structure of the vibrating filter mechanism member 34 according to the third embodiment is particularly advantageous in the case where the component to be suspended by the vibrating filter mechanism component 33 is the shielding device 3.

By means of the invention, such a structure of the vibrating filtering mechanical member is simplified, ensuring a reduction in the transmission of vibrations from the electromechanical actuator to the apparatus, while minimizing the manufacturing costs of the vibrating filtering mechanical assembly and, consequently, of the electromechanical actuator.

Thus, the vibration filtering mechanical component is convenient for industrial production.

The structure of the vibrating filtering mechanical member may allow the intermediate portion to deform, allowing torsion to be created at the junction between the intermediate portion and the first end portion.

The structure of the vibrating filter mechanism also allows to minimize its length, thus allowing to obtain a vibrating filter mechanism assembly that is compact, so as to minimize the length of the electromechanical actuator.

In addition, the first arm of the first end portion may ensure a high torsional stiffness and a low bending stiffness of the vibrating filtering mechanical member.

In addition, such a vibration filter mechanical assembly is particularly suitable for electromechanical actuators having a small diameter housing.

Of course, many modifications may be made to the foregoing embodiments without departing from the scope of the invention as defined by the claims.

In a variant not shown, the second end portion 39 may be devoid of the arm 41. In this case, the intermediate portion 36 is connected by a solid wall to the second ring 40 of the second end portion 39.

Advantageously, the solid wall of the second ring 40, which connects the intermediate portion 36 to the second end portion 39, may extend along a direction parallel to or coinciding with a plane P orthogonal to the longitudinal axis X34, or along a direction inclined with respect to the longitudinal axis X34.

In a variant not shown, the electromechanical actuator 11 is devoid of the viscoelastic element 51, in particular the viscoelastic element 51, if, in the assembled configuration of the electromechanical actuator 11 and during its operation, a sufficient clearance is provided between the housing 17 and the torque support 21 so as to prevent the housing 17 from striking the torque support 21.
