Title: Electromechanical actuator and closure, covering or solar protection installation comprising such an electromechanical actuator

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to an electromechanical actuator comprising a torque support, intended to be assembled at least partly inside a casing of the electromechanical actuator, as well as a closure, covering or solar protection installation comprising a screen which can be rolled on a winding tube driven in rotation by such an electromechanical actuator. 
     Generally, the present invention relates to the field of covering devices comprising a motorized drive device moving a screen, between at least a first position and at least a second position. 
     A motorized drive device comprises an electromechanical actuator of a movable closure, covering or solar protection element, such as a shutter, a door, a grid, a blind or any other equivalent material, hereinafter called a screen. 
     Description of the Related Art 
     Electromechanical actuators are already known, such as for example in WO 2019/072842 A1, for a closure, covering or solar protection installation. These electromechanical actuators comprise an electric motor, a casing, and a torque support. The electric motor is assembled within the casing, in an assembled configuration of the electromechanical actuator. The torque support is arranged at a first end of the casing, in the assembled configuration of the electromechanical actuator. The torque support comprises two assembly elements. These assembly elements of the torque support are two notches, each in the form of a radial projection, diametrically opposed relative to an axis of rotation of the electromechanical actuator. In addition, the casing comprises two assembly elements. These assembly elements of the casing are two diametrically opposed indentations, relative to the axis of rotation. The notches of the torque support are configured to be assembled with the indentations of the casing, in the assembled configuration of the electromechanical actuator, so as to rotationally block the torque support to the casing. 
     However, these electromechanical actuators present the disadvantage that the two assembly elements of the torque support are identical and the two assembly elements of the casing are identical. 
     In this way, the assembly elements of the torque support and of the casing only allow the torque support to be assembled relative to the casing according to a first position or according to a second position, with a 180° orientation relative to each other, in a functional assembly configuration of the electromechanical actuator. 
     The functional assembly configuration of the electromechanical actuator corresponds to a final assembly configuration of the electromechanical actuator in which the electromechanical actuator is suitable for use in the closure, covering or solar protection installation. 
     The first and second assembly positions of the torque support relative to the casing allow for ease of industrialization of the electromechanical actuator, since the torque support and the casing are respectively symmetrical around the axis of rotation. 
     Therefore, the assembly of the torque support relative to the casing has only two assembly positions to ensure a functional assembly of the electromechanical actuator. 
     SUMMARY OF THE INVENTION 
     The present invention is intended to solve the aforementioned disadvantages and to provide an electromechanical actuator for a closure, covering or solar protection installation, as well as a closure, covering or solar protection installation comprising such an electromechanical actuator, which makes it possible to guarantee an assembly of a torque support of the electromechanical actuator relative to a casing of the electromechanical actuator according to at least a first position, in a first functional assembly configuration of the electromechanical actuator, and according to at least a second position, in an additional second assembly configuration of the electromechanical actuator, different from the first functional assembly configuration of the electromechanical actuator. 
     In this regard, the present invention is directed, according to a first aspect, to an electromechanical actuator for a closure, covering or solar protection installation, 
     the electromechanical actuator comprising at least:
         an electric motor,   a casing, the electric motor being mounted within the casing in an assembled configuration of the electromechanical actuator, the casing comprising at least an assembly element, and   a torque support, the torque support arranged at a first end of the casing in the assembled configuration of the electromechanical actuator, the torque support comprising at least a first assembly element.       

     The first assembly element of the torque support is configured to be assembled with the assembly element of the casing, according to a first assembly configuration of the torque support relative to the casing, the first assembly configuration corresponding to a functional assembly configuration of the electromechanical actuator. 
     According to the invention, the torque support comprises, in addition, at least a second assembly element. The second assembly element of the torque support is different from the first assembly element of the torque support. The second assembly element of the torque support is configured to be assembled with the assembly element of the casing, according to a second assembly configuration of the torque support relative to the casing, the second assembly configuration corresponding to a testing configuration of the electromechanical actuator. The torque support is configured to be oriented relative to the casing, around an axis of rotation of the electromechanical actuator and in the first assembly configuration, with a first orientation of the torque support relative to the casing. The torque support is also configured to be oriented relative to the casing, around the axis of rotation and in the second assembly configuration, with a second orientation of the torque support relative to the casing. In addition, the first and second orientations of the torque support relative to the casing are offset from each other, around the axis of rotation, by a predetermined non-zero angular value. 
     Thus, the first assembly element of the torque support is different from the second assembly element of the torque support, such that, according to the first assembly configuration of the torque support relative to the casing, the first assembly element of the torque support is assembled with the assembly element of the casing to ensure a functional assembly configuration of the electromechanical actuator and that, according to the second assembly configuration of the torque support relative to the casing, the second assembly element of the torque support is assembled with the assembly element of the casing to ensure a testing configuration of the electromechanical actuator. 
     In this manner, such an electromechanical actuator ensures that the torque support is assembled relative to the casing according to at least a first position, in a first functional assembly configuration of the electromechanical actuator, and according to at least a second position, in an additional second electromechanical actuator assembly configuration that is the testing configuration of the electromechanical actuator and is therefore different from the first functional assembly configuration of the electromechanical actuator. 
     According to an advantageous feature of the invention, the torque support comprises at least a notch. In addition, the notch of the torque support is configured to be closed by the casing, in the first assembly configuration, and to be open relative to the casing, in the second assembly configuration. 
     According to another advantageous feature of the invention, the notch of the torque support is provided in the or each second assembly element of the torque support. 
     According to another advantageous feature of the invention, the notch of torque support is configured for the passage of at least a power supply cable, from the interior of the casing to the exterior of the casing, in the second assembly configuration. 
     According to another advantageous feature of the invention, the first and second orientations of the torque support relative to the casing are determined by an angular positioning of the first assembly element of the torque support relative to the second assembly element of the torque support, around the axis of rotation. 
     According to another advantageous feature of the invention, each of the first and second assembly elements of the torque support and the assembly element of the casing are press-fit assembly elements. In addition, each of the first and second assembly elements of the torque support is configured to cooperate with the assembly element of the casing in a form-fitting manner. 
     According to another advantageous feature of the invention, the first assembly element of the torque support comprises a first stop. The second assembly element of the torque support comprises a second stop. The casing comprises an edge at the first end of the casing. The edge of the casing is configured to abut the first stop of the first assembly element of the torque support, in the first assembly configuration, so that the torque support is inserted partially within the casing according to a first predetermined distance parallel to an axis of rotation of the electromechanical actuator. The edge of the casing is also configured to abut the second stop of the second assembly element of the torque support, in the second assembly configuration, so that the torque support is inserted partially within the casing according to a second predetermined distance parallel to the axis of rotation. In addition, the first predetermined distance is greater than the second predetermined distance. 
     According to another advantageous feature of the invention, the electromechanical actuator comprises at least a battery, the battery being arranged inside the casing, in the assembled configuration of the electromechanical actuator. 
     According to another advantageous feature of the invention, the electromechanical actuator comprises an electronic control unit. In addition, the electronic control unit is configured to be electrically connected to a control tool via an electrical connection, in the second assembly configuration. 
     According to another advantageous feature of the invention, in the second assembly configuration, the electrical connection between the electronic control unit and the control tool is implemented by the power supply cable extending through the notch provided in the torque support. 
     The present invention is directed, according to a second aspect, to a closure, covering or solar protection installation comprising a screen, a winding tube and an electromechanical actuator, according to the invention and as mentioned above, the screen being able to be rolled on the winding tube and the winding tube being arranged so as to be driven in rotation by the electromechanical actuator.

In other words, the first two assembly elements  38  of the torque support  21  are diametrically opposed relative to the axis of rotation X. The two second assembly elements  39  of the torque support  21  are arranged at an angle of 180° to each other, around the axis of rotation X. In other words, the two second assembly elements  39  of the torque support  21  are diametrically opposed relative to the axis of rotation X. 
     The number and angular position of the first and second assembly elements of the torque support are not limiting and may be different and, more particularly, are dependent on the number of assembly elements of the casing. The first and second assembly elements of the torque support may be one or strictly greater than two and, for example, three in number and arranged at an angle of 120° relative to each other, around the axis of rotation.

     Here, each first assembly element  38  of the torque support  21  is formed by a recessed area of the torque support  21 , in other words by a deformation in the direction of the axis of rotation X. In addition, each second assembly element  39  of the torque support  21  is formed by a recessed area of the torque support  21 , in other words by a deformation in the direction of the axis of rotation X. 
     Here, the first assembly elements  38  are identical to each other and the second assembly elements  39  are identical to each other. 
     Each first assembly element  38  of the torque support  21  is configured to be assembled, in other words is assembled, with one of the assembly elements  37  of the casing  17 , according to the first assembly configuration of the torque support  21  relative to the casing  17 . The first assembly configuration corresponds to a functional assembly configuration of the electromechanical actuator  11 . 
     The functional assembly configuration of the electromechanical actuator  11  corresponds to a final assembly configuration of the electromechanical actuator  11  wherein the electromechanical actuator  11  is suitable for use in the installation  6 , in other words assembled and configured to rotate the winding tube  4  of the covering device  3 . 
     According to the first assembly configuration, the torque support  21  is oriented and rotationally blocked around the axis of rotation X relative to the casing  17 , via the first assembly elements  38  of the torque support  21  and assembly elements  37  of the casing  17 . 
     Each second assembly element  39  of the torque support  21  is different from a first assembly element  38  of the torque support  21 . 
     Here, each second assembly element  39  has a different shape than that of a first assembly element  38 .

The second assembly configuration corresponds to a testing configuration of the electromechanical actuator  11 . 
     According to the second assembly configuration, the torque support  21  is oriented and rotationally blocked around the axis of rotation X relative to the casing  17 , via the second assembly elements  39  of the torque support  21  and assembly elements  37  of the casing  17 . 
     Thus, the or each first assembly element  38  of the torque support  21  is different from the or each second assembly element  39  of the torque support  21 , such that, according to the first assembly configuration of the torque support  21  relative to the casing  17 , the or each first assembly element  38  of the torque support  21  is assembled, in other words is configured to be assembled, with the or one of the assembly elements  37  of the casing  17  to ensure a functional assembly configuration of the electromechanical actuator  11 , and that, according to the second assembly configuration of the torque support  21  relative to the casing  17 , the or each second assembly element  39  of the torque support  21  is assembled, in other words is configured to be assembled, with the or one of the assembly elements  37  of the casing  17  to ensure a testing configuration of the electromechanical actuator  11 . In this way, such an electromechanical actuator  11  allows to ensure an assembly of the torque support  21  relative to the casing  17  according to at least a first position, in a first functional assembly configuration of the electromechanical actuator  11 , and according to at least a second position, in a second additional assembly configuration of the electromechanical actuator  11  which is the one of the testing of the electromechanical actuator  11  and which is therefore different from the first functional assembly configuration of the electromechanical actuator  11 . 
     The torque support  21  can thus be assembled relative to the casing  17  according to at least two distinct positions, in particular according to the first and second assembly configurations, of which a first assembly position of the torque support  21  relative to the casing  17  is a functional assembly position of the electromechanical actuator  11 , where the torque support  21  is configured to be attached to the casing  17 , and a second assembly position of the torque support  21  relative to the casing  17  is a testing position of the electromechanical actuator  11 , where the testing position is different from the functional assembly position of the electromechanical actuator  11 . 
     Furthermore, such an electromechanical actuator  11  allows the torque support  21  to be assembled relative to the casing  17  according to the first and second assembly configurations at the same workstation of a manufacturing unit, so as to minimize an assembly time of the electromechanical actuator  11  and to limit investments for obtaining the manufacturing unit.
