Description

Technical Field

[0001] The present invention relates to an electromechanical actuator for a shielding device, namely an electromechanical actuator for a shielding device.

[0002] The present invention also relates to a shielding device comprising a shielding element movable by the electromechanical actuator.

[0003] Generally, the present invention relates to the field of shielding devices including an electrically driven device for moving a shield between at least one first position and at least one second position, and possibly between at least one third position and at least one fourth position.

[0004] More specifically, the present invention relates to the field of concealing devices comprising at least one concealing element, a first movable rod, a second movable rod, and an electrically driven device. In an assembly configuration of the concealing device, the first movable rod is arranged between the upper part of the window or door and the second movable rod. The second movable rod is positioned between the first movable rod and the lower part of the window or door. The concealing element is arranged between the first movable rod and the second movable rod. The concealing element is configured to be moved by an electrically driven device. The electrically driven device moves the first movable rod connected to the concealing element between at least one first position and at least one second position, and moves the second movable rod connected to the concealing element between at least one third position and at least one fourth position.

[0005] Electric drive units include electromechanical actuators for movable shielding or shading elements (such as sunshades or any other equivalent devices, referred to below as shielding elements). Background Technology

[0006] US 2008 / 0102965 A1 describes an electromechanical actuator including a housing, an electric motor, a gearbox, a coupling element, and a torque transmission device. The electric motor, gearbox, and torque transmission device are housed within the housing. The gearbox is coupled to the coupling element via the torque transmission device.

[0007] The torque transmission device includes a transmission element and a guide element. The transmission element includes a receiving orifice on a first side and a protruding element on a second side opposite to the first side. The guide element includes a first groove on a first side and a second groove on a second side opposite to the first side. The first groove and the second groove are perpendicular to each other. The coupling element includes a protruding element on a first side and an orifice on a second side opposite to the first side, the orifice being configured for coupling with a shaft.

[0008] In the assembly configuration of the electromechanical actuator, the gearbox is connected to the transmission element by inserting the output shaft of the gearbox into the receiving port of the transmission element. The transmission element is connected to the guide element by inserting the protruding element of the transmission element into the first groove of the guide element. Furthermore, the connecting element is connected to the guide element by inserting the protruding element of the connecting element into the second groove of the guide element.

[0009] Therefore, the electromechanical actuator includes a first connection between the transmission element and the guide element and a second connection between the guide element and the connecting element, which together constitute an assembly called an "Oldham coupling".

[0010] This assembly between the transmission elements, guide elements, and connecting elements allows for the correction of misalignment of the rotation axes of these elements, especially when the output shaft of the gearbox is rotated by the electrical activation of the electric motor.

[0011] However, the disadvantage of assembling the electromechanical actuator in this way is that it can only correct slight misalignments of the rotation axes of the transmission element, guide element, and connecting element, and can only transmit a small amount of torque from the motor to the connecting element through the torque transmission device.

[0073] First, refer to Figure 1 This describes an apparatus 1 including a closing, concealing, or sunshade device 3 according to a first embodiment of the invention. The apparatus 1 is installed in a building (not shown) and includes an opening (not shown) through which windows or doors (not shown) are arranged. The apparatus 1 is equipped with a shielding member 2 belonging to the closing, concealing, or sunshade device 3, particularly an electrically operated sunshade. The shielding member 2 is configured to at least partially conceal the opening arranged in the building wall.

[0074] The closing, shielding, or sunshade device 3 is referred to below as the "shading device". The shading device 3 includes the shielding element 2.

[0075] Here, the shielding element 2 may be formed, for example, from pleated or honeycomb fabric or oriented slats.

[0076] The shielding member 2 includes a first end 2a (particularly the upper end) and a second end 2b (particularly the lower end), with the second end 2b opposite to the first end 2a.

[0077] Reference Figure 1 The present invention describes a sunshade according to a first embodiment.

[0078] The shielding device 3 includes a first movable rod 8a, particularly an upper movable rod. The first end 2a of the shielding member 2 is connected to the first movable rod 8a.

[0079] Here, the shielding device 3 also includes a second movable rod 8b, specifically a lower movable rod. The second end 2b of the shielding member 2 is connected to the second movable rod 8b.

[0080] Therefore, the shielding member 2 is arranged, that is, configured to extend between the first movable rod 8a and the second movable rod 8b. The degree to which the shielding member 2 extends varies depending on the relative position of the first movable rod 8a and the second movable rod 8b.

[0081] Here, the second movable lever 8b is the same as the first movable lever 8a.

[0082] In a variant not shown, the second movable lever 8b differs from the first movable lever 8a.

[0084] Advantageously, the shielding device 3 also includes a housing portion 7. The electric drive unit 5 is mounted, i.e., housed within the housing portion 7, particularly in the assembly configuration of the shielding device 3. The housing portion 7 is mounted, i.e., configured to be installed at or above the opening, particularly in the assembly configuration of the shielding device 3 in the device 1. The housing portion 7 is generally referred to as a guide rail, more specifically as a top rail.

[0085] Advantageously, the housing portion 7 has a U-shaped cross-section. That is, the housing portion 7 includes a bottom wall 7a and two side walls 7b. Each side wall 7b is connected to the bottom wall 7a of the housing portion 7. Furthermore, each side wall 7b is perpendicular to the bottom wall 7a of the housing portion 7.

[0089] The electromechanical actuator 11 includes a first end 11a and a second end 11b, with the second end 11b opposite to the first end 11a.

[0090] Here, in device 1, the high-stroke end position corresponds to the position where the first movable rod 8a can no longer move upwards, especially when it is close to the housing portion 7. The high-stroke end position can be predetermined, or it can correspond to the first movable rod 8a abutting against the housing portion 7. Furthermore, the low-stroke end position corresponds to the position where the second movable rod 8b can no longer move downwards, especially away from the housing portion 7 or the first movable rod 8a. The low-stroke end position can be predetermined, or it can correspond to the second movable rod 8b abutting against the edge of the opening, or it can correspond to the full deployment of the shielding member 2.

[0091] Advantageously, the electric drive unit 5 includes at least one drive shaft 9a, 9b. Furthermore, the electromechanical actuator 11 is configured to rotate, i.e., rotate the drive shafts 9a, 9b, in order to move one or each of the first movable rod 8a and the second movable rod 8b.

[0092] Here, the electric drive unit 5 includes a first drive shaft 9a and a second drive shaft 9b. Furthermore, the electromechanical actuator 11 is configured to rotate, i.e., rotate the first drive shaft 9a to move the first movable rod 8a, and is configured to rotate, i.e., rotate the second drive shaft 9b to move the second movable rod 8b.

[0093] Advantageously, the first drive shaft 9a and the second drive shaft 9b are parallel to each other.

[0094] Here, the first drive shaft 9a and the second drive shaft 9b are located on the same side of the electromechanical actuator 11, as shown below. Figure 1 As shown.

[0095] Advantageously, the shielding device 3 includes a first pull cord 4a, a second pull cord 4b, a first drive device 6a, and a second drive device 6b.

[0097] Therefore, when the first pull rope 4a and the second pull rope 4b are wound around the first drive device 6a and the second drive device 6b, the first movable rod 8a rises toward the housing portion 7. Furthermore, when the first pull rope 4a and the second pull rope 4b are unwound by the first drive device 6a and the second drive device 6b, the first movable rod 8a lowers away from the housing portion 7.

[0098] Advantageously, each of the first pull rope 4a and the second pull rope 4b is attached to the first movable rod 8a.

[0099] Here, the shielding device 3 also includes a third pull rope 4c, a fourth pull rope 4d, a third drive device 6c, and a fourth drive device 6d. The third drive device 6c is configured to cooperate with the third pull rope 4c. Furthermore, the fourth drive device 6d is configured to cooperate with the fourth pull rope 4d. Additionally, the electromechanical actuator 11 is configured to move via the third pull rope 4c and the fourth pull rope 4d, i.e., to move the second movable rod 8b.

[0101] Therefore, when the first pull rope 4a and the second pull rope 4d are wound around the first drive device 6a and the second drive device 6d, the first movable rod 8a rises toward the housing portion 7. Furthermore, when the first pull rope 4a and the second pull rope 4d are unwound by the first drive device 6a and the second drive device 6d, the first movable rod 8a lowers away from the housing portion 7.

[0102] Advantageously, both the third pull rope 4c and the fourth pull rope 4d are attached to the second movable rod 8b.

[0103] Therefore, the first pull rope 4a, the second pull rope 4b, the third pull rope 4c, and the fourth pull rope 4d connect the first drive shaft 9a and the second drive shaft 9b to the first movable rod 8a and the second movable rod 8b.

[0104] In this way, the first pull rope 4a, the second pull rope 4b, the third pull rope 4c, and the fourth pull rope 4d support the shielding member 2.

[0105] Here, the third drive device 6c and the fourth drive device 6d are the same as the first drive device 6a and the second drive device 6b, respectively.

[0109] Therefore, the electric drive unit 5 is configured to move via the electromechanical actuator 11 through the first pull rope 4a, the second pull rope 4b, the third pull rope 4c and the fourth pull rope 4d, that is, to move the first movable rod 8a and the second movable rod 8b of the shielding device 3, particularly in the vertical direction.

[0110] Advantageously, the first movable rod 8a and the second movable rod 8b are parallel to each other, especially in the assembly configuration of the shielding device 3. Furthermore, the first drive shaft 9a and the second drive shaft 9b are parallel to the first movable rod 8a and the second movable rod 8b, especially in the assembly configuration of the shielding device 3.

[0111] In a variant not shown, the first drive shaft 9a is connected to the second movable rod 8b, and the second drive shaft 9b is connected to the first movable rod 8a, instead of the first drive shaft 9a being connected to the first movable rod 8a and the second drive shaft 9b being connected to the second movable rod 8b as described above.

Furthermore, the first end 21a of the rotor 21 of the motor 16 is connected to the second clutch 23b via the coupling device 33. In this case, the electromechanical actuator 11 may also include a connecting shaft. Furthermore, particularly in the assembly configuration of the electromechanical actuator 11, the connecting shaft is coupled, i.e., configured to be connected on one side to the coupling device 33 (particularly the output shaft of the coupling device 33) and on the other side to the second clutch 23b (particularly the input shaft 25 of the second clutch 23b). Advantageously, the connecting shaft is a rigid shaft. Advantageously, the electromechanical actuator 11 also includes at least one first universal joint and a second universal joint. The coupling device 33, particularly in the assembly configuration of the electromechanical actuator 11, is assembled with the connecting shaft via the first universal joint. Furthermore, the second clutch 23b, particularly in the assembly configuration of the electromechanical actuator 11, is assembled to the connecting shaft via a second universal joint. Thus, the first and second universal joints, via the connecting shaft, ensure torque transmission between the coupling device 33 and the second clutch 23b, while compensating for positional misalignment between the output shaft of the coupling device 33 and the input shaft 25 of the second clutch 23b. Advantageously, at least a portion of the control unit 15 is arranged between the coupling device 33 and the second clutch 23b, particularly in the assembly configuration of the electromechanical actuator 11, along the second rotation axis Xb. Furthermore, the connecting shaft extends along the second rotation axis Xb, passing through the region of the electromechanical actuator 11 including the control unit 15. This region of the electromechanical actuator 11 is defined along the second rotation axis Xb between the coupling device 33 and the second clutch 23b.

[0270] If the first clutch 23a is engaged, the motion generated by the electric motor 16 is transmitted to the first drive shaft 9a via the first clutch 23a, the first gearbox 19a, and the first coupling element 20a. If the second clutch 23b is engaged, the same motion generated by the electric motor 16 is also transmitted to the second drive shaft 9b via the coupling device 33, the second clutch 23b, the second gearbox 19a, and the second coupling element 20a.

[0271] Therefore, the electromechanical actuator 11 uses the single motor 16 and control unit 15 to drive the shield 2 in a variety of ways.

[0272] With the first clutch 23a and the second clutch 23b engaged and the motor 16 energized, the motion generated by the motor 16 is transmitted to the first drive shaft 9a and the second drive shaft 9b, which then rotate about the first rotation axis Xa and the second rotation axis Xb, respectively. In this case, the first movable lever 8a and the second movable lever 8b simultaneously perform the same vertical movement. This allows for selection of the location of the area where the opening is obscured.

[0273] With only the first clutch 23a engaged and the motor 16 energized, the motion generated by the motor 16 is transmitted only to the first drive shaft 9a. In this case, only the first movable lever 8a moves vertically, while the second movable lever 8b remains stationary. Therefore, the height of the shielding area is modified relative to the opening.

[0274] Similarly, when only the second clutch 23b is engaged and the motor 16 is energized, the motion generated by the motor 16 is transmitted only to the second drive shaft 9b. In this case, only the second movable lever 8b moves vertically, while the first movable lever 8a remains stationary. Therefore, the height of the shielding area is modified relative to the opening.

[0275] Therefore, the first movable lever 8a and the second movable lever 8b can be moved vertically individually or simultaneously by the electromechanical actuator 11.

[0276] Now, according to the first embodiment of the present invention, referring to... Figure 4 and Figure 5 To describe in more detail what belongs to Figures 1 to 3 The electromechanical actuator 11 shown has a first torque transmission device 10a and a second torque transmission device 10b.

[0277] The first torque transmission device 10a and the second torque transmission device 10b respectively include a drive shaft 38, a first pin 39 and a second pin 40.

[0278] The drive shaft 38 includes a first end 38a and a second end 38b. The second end 38b is opposite to the first end 38a.

[0279] The first pin 39 includes a first end 39a and a second end 39b. The second end 39b is opposite to the first end 39a.

[0280] The second pin 40 includes a first end 40a and a second end 40b. The second end 40b is opposite to the first end 40a.

[0281] Advantageously, the drive shaft 38 is made of metal. Furthermore, the first pin 39 and the second pin 40 are also made of metal.

[0282] The drive shaft 38 also includes a first opening 41 and a second opening 42.

[0283] A first opening 41 is arranged at the first end 38a of the drive shaft 38. A first pin 39 is received, i.e. installed, inside the first opening 41, particularly in the assembly configuration of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0284] The second opening 42 is arranged at the second end 38b of the drive shaft 38. The second pin 40 is accommodated, i.e. installed inside the second opening 42, particularly in the assembly configuration of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0285] Advantageously, the first pin 39 is fixed, i.e., configured to be fixed inside the first opening 41 of the drive shaft 38, and the second pin 40 is fixed inside the second opening 42 of the drive shaft 38, particularly in the assembly configuration of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0286] Here, the first pin 39 is press-fitted, i.e., configured to press-fit inside the first opening 41 of the drive shaft 38, and the second pin 40 is press-fitted, i.e. configured to press-fit inside the second opening 42 of the drive shaft 38, particularly in the assembly configuration of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0287] Advantageously, both the first opening 41 and the second opening 42 in the drive shaft 38 are through holes with a circular cross-section.

[0288] Advantageously, the first pin 39 has a first longitudinal axis X39, and the second pin 40 has a second longitudinal axis X40. Furthermore, the first longitudinal axis X39 and the second longitudinal axis X40 are arranged in the same plane P10.

[0289] Therefore, the first pin 39 and the second pin 40 have the same angular position within the first torque transmission device 10a (and the second torque transmission device 10b, respectively).

[0290] In this way, the angular positioning of the first pin 39 and the second pin 40 ensures the constant speed operation of the first torque transmission device 10a (and the second torque transmission device 10b, respectively), that is, the rotational speed of the output shaft of the first gearbox 19a (and the second gearbox 19b, respectively) and the first connecting element 20a (and the second connecting element 20b, respectively) is the same at every moment, even though they are not aligned.

[0291] The first gearbox 19a includes a first housing portion 43. The first connecting element 20a includes a second housing portion 44. The first end 38a of the drive shaft 38 of the first torque transmission device 10a is arranged, i.e., configured to be arranged (particularly in the assembly configuration of the electromechanical actuator 11) inside the first housing portion 43 of the first gearbox 19a. Furthermore, the second end 38b of the drive shaft 38 of the first torque transmission device 10a is arranged, i.e., configured to be arranged (particularly in the assembly configuration of the electromechanical actuator 11) inside the second housing portion 44 of the first connecting element 20a. Similarly, the second gearbox 19b includes a first housing portion 43. The second connecting element 20b includes a second housing portion 44. The first end 38a of the drive shaft 38 of the second torque transmission device 10b is arranged, i.e., configured to be arranged (particularly in the assembly configuration of the electromechanical actuator 11) inside the first housing portion 43 of the second gearbox 19b. Furthermore, the second end 38b of the drive shaft 38 of the second torque transmission device 10b is arranged, i.e., configured to be arranged (particularly in the assembly configuration of the electromechanical actuator 11) inside the second housing portion 44 of the second connecting element 20b.

[0292] X10a and X10b are the rotation axes of the first torque transmission device 10a and the second torque transmission device 10b, respectively, and can also be referred to as the second rotation axes. Each rotation axis X10a and X10b is the rotation axis of the first housing portion 43 of the first gearbox 19a or the second gearbox 19b.

[0293] X20a and X20b are the rotation axes of the first connecting element 20a and the second connecting element 20b, respectively, and can also be referred to as the first rotation axis. Each rotation axis X20a and X20b is the rotation axis of the second housing portion 44 of the first connecting element 20a or the second connecting element 20b.

[0294] Here, the first rotation axis Xa and the second rotation axis Xb of the first drive shaft 9a and the second drive shaft 9b coincide with the rotation axes X20a and X20b of the first connecting element 20a and the second connecting element 20b.

[0295] Therefore, when the rotation axis X10a of the first torque transmission device 10a is not aligned with the rotation axis X20a of the first connecting element 20a, this design of the electromechanical actuator 11 enables, i.e., it is configured to transmit torque, especially large torque, from the electric motor 16 to the first connecting element 20a via the first torque transmission device 10a. When the rotation axis X10b of the second torque transmission device 10b is not aligned with the rotation axis X20b of the second connecting element 20b, this design of the electromechanical actuator 11 also enables, i.e., it is configured to transmit torque, especially large torque, from the electric motor 16 via the second torque transmission device 10b to the second connecting element 20b.

[0296] Here, for example Figure 3 As shown, the first misalignment value D1 between the rotation axis X10a of the first torque transmission device 10a and the rotation axis X20a of the first connecting element 20a is different from the second misalignment value D2 between the rotation axis X10b of the second torque transmission device 10b and the rotation axis X20b of the second connecting element 20b. Advantageously, these misalignment values ​​D1 and D2 are measured in plane P.

[0297] Therefore, the difference between the first misalignment value D1 of the rotation axis X10a of the first torque transmission device 10a relative to the rotation axis X20a of the first connecting element 20a and the second misalignment value D2 of the rotation axis X10b of the second torque transmission device 10b relative to the rotation axis X20b of the second connecting element 20b allows the electromechanical actuator 11 to adapt to different dimensions of the housing portion 7, especially its width L.

[0298] In fact, the distance between the first axis Xa and the second axis Xb (the axes X20a and X20b of the first connecting element 20a and the second connecting element 20b are respectively aligned thereon) can vary depending on the size of the housing part 7 (especially its width L), while the distance between the axes X10a and X10b of the first torque transmission device 10a and the second torque transmission device 10b remains constant, regardless of which housing part 7 the electromechanical actuator 11 is installed in.

[0299] In a variant not shown, in the assembly configuration of the shielding device 3, the first misalignment value D1 between the rotation axis X10a of the first torque transmission device 10a and the rotation axis X20a of the first connecting element 20a is equal to the second misalignment value D2 between the rotation axis X10b of the second torque transmission device 10b and the rotation axis X20b of the second connecting element 20b.

[0300] Advantageously, the first end 38a and the second end 38b of the drive shaft 38 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are both spherical, and in particular convex. Furthermore, the first housing portion 43 of the first gearbox 19a (and the second gearbox 19b respectively) and the second housing portion 44 of the first connecting element 20a (and the second connecting element 20b respectively) have rotational shapes about rotation axes X10a, X10b, X20a, X20b, and in particular concave.

[0301] Here, the first gearbox 19a also includes a first interface element 45a. Furthermore, the second gearbox 19b also includes a second interface element 45b.

[0302] Advantageously, the first housing portion 43 of the first gearbox 19a is arranged inside the first interface element 45a. Furthermore, the first housing portion 43 of the second gearbox 19b is arranged inside the second interface element 45b.

[0303] Advantageously, the first torque transmission device 10a (and the second torque transmission device 10b respectively) further includes a first transmission element 50 and a second transmission element 51.

[0304] Advantageously, the first transmission element 50 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) is fixed, i.e., configured to be fixed (particularly in the assembly configuration of the electromechanical actuator 11) on the first pin 39 of the first torque transmission device 10a (and the second torque transmission device 10b respectively). Furthermore, the second transmission element 51 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) is fixed, i.e., configured to be fixed (particularly in the assembly configuration of the electromechanical actuator 11) on the second pin 40 of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0305] Advantageously, the first gearbox 19a, particularly the first interface element 45a (and the second gearbox 19b, particularly the second interface element 45b), includes a first recess 46. The first recess 46 leads into the interior of the first housing portion 43 of the first gearbox 19a (and the second gearbox 19b).

[0306] Advantageously, the first connecting element 20a (and the second connecting element 20b respectively) includes a second recess 47. The second recess 47 opens into the interior of the second housing portion 44 of the first connecting element 20a (and the second connecting element 20b respectively).

[0307] Advantageously, the first transmission element 50 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) is accommodated, i.e., installed (particularly in the assembly configuration of the electromechanical actuator 11) inside the first recess 46 of the first gearbox 19a (and the second gearbox 19b respectively). Furthermore, the second transmission element 51 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) is accommodated, i.e., installed (particularly in the assembly configuration of the electromechanical actuator 11) inside the second recess 47 of the first connecting element 20a (and the second connecting element 20b respectively).

[0308] Therefore, the first transmission element 50 of the first torque transmission device 10a is arranged inside the first recess 46 of the first gearbox 19a, maximizing the bearing surface between the first pin 39 of the first torque transmission device 10a and the first gearbox 19a (particularly the first interface element 45a). Furthermore, the second transmission element 51 of the first torque transmission device 10a is arranged inside the second recess 47 of the first connecting element 20a, maximizing the bearing surface between the second pin 40 of the first torque transmission device 10a and the first connecting element 20a. Similarly, the first transmission element 50 of the second torque transmission device 10b is arranged inside the first recess 46 of the second gearbox 19b, maximizing the bearing surface between the first pin 39 of the second torque transmission device 10b and the second gearbox 19b (particularly the second interface element 45b). Furthermore, the second transmission element 51 of the second torque transmission device 10b is arranged inside the second recess 47 of the second connecting element 20b, maximizing the bearing surface between the second pin 40 of the second torque transmission device 10b and the second connecting element 20b.

[0309] In this way, the first transmission element 50 of the first torque transmission device 10a is arranged inside the first recess 46 of the first gearbox 19a, thereby reducing stress on the first pin 39 of the first torque transmission device 10a and the first gearbox 19a (particularly the first interface element 45a). Furthermore, the second transmission element 51 of the first torque transmission device 10a is arranged inside the second recess 47 of the first connecting element 20a, thereby reducing stress on the second pin 40 of the first torque transmission device 10a and the first connecting element 20a. Similarly, the first transmission element 50 of the second torque transmission device 10b is arranged inside the first recess 46 of the second gearbox 19b, reducing stress on the first pin 39 of the second torque transmission device 10b and the second gearbox 19b (particularly the second interface element 45b). Furthermore, the second transmission element 51 of the second torque transmission device 10b is arranged inside the second recess 47 of the second connecting element 20b, thereby reducing stress on the second pin 40 of the second torque transmission device 10b and the second connecting element 20b.

[0310] exist Figure 6 and Figure 7 In the second embodiment shown, elements similar to those in the first embodiment have the same reference numerals and operate as described above. Only the main differences between this second embodiment and the previous embodiment are described below. In the following description, if reference numerals are used but not explicitly stated in the original text... Figure 6 and Figure 7 Reproduced in, or in Figure 6 and Figure 7 If it appears in the text but is not mentioned in the description, then it corresponds to... Figures 1 to 5 One of the objects that have the same reference numerals.

[0311] Reference Figure 6 and Figure 7 The electromechanical actuator 11 according to a second embodiment of the present invention will now be described, more specifically the first torque transmission device 10a and the second torque transmission device 10b.

[0312] Here, the first torque transmission device 10a (and the second torque transmission device 10b) does not include the first transmission element 50 and the second transmission element 51.

[0313] Here, the first end 38a and the second end 38b of the drive shaft 38 of the first torque transmission device 10a (and the second torque transmission device 10b, respectively) are both spherical. Furthermore, the first housing portion 43 of the first gearbox 19a (and the second gearbox 19b, respectively) and the second housing portion 44 of the first connecting element 20a (and the second connecting element 20b, respectively) have rotational shapes about rotation axes X10a, X10b, X20a, and X20b, particularly cylindrical shapes.

[0314] Therefore, the spherical shape of the first end 38a and the second end 38b of the drive shaft 38 of the first torque transmission device 10a enables these first ends 38a and the second end 38b to be held in positions inside the first housing portion 43 of the first gearbox 19a and the second housing portion 44 of the first connecting element 20a, respectively. That is, they are configured to hold the positions of these first ends 38a and the second end 38b, which are cylindrical in shape, while ensuring that the first end 38a and the second end 38b of the drive shaft 38 of the first torque transmission device 10a are connected in a ball-and-socket manner inside the first housing portion 43 of the first gearbox 19a and the second housing portion 44 of the first connecting element 20a, respectively.

[0315] Furthermore, the spherical shape of the first end 38a and the second end 38b of the drive shaft 38 of the second torque transmission device 10b enables these first ends 38a and the second end 38b to be held in positions inside the first housing portion 43 of the second gearbox 19b and the second housing portion 44 of the second connecting element 20b, respectively. That is, they are configured to hold the positions of these first ends 38a and the second end 38b, which are cylindrical in shape, while ensuring that the first end 38a and the second end 38b of the drive shaft 38 of the second torque transmission device 10b are connected in a ball-and-socket manner inside the first housing portion 43 of the second gearbox 19b and the second housing portion 44 of the second connecting element 20b, respectively.

[0316] Here, the first gearbox 19a (and the second gearbox 19b respectively) includes two first recesses 46. Each first recess 46 leads into the interior of the first housing portion 43 of the first gearbox 19a (and the second gearbox 19b respectively).

[0317] Advantageously, the first recess 46 of the first gearbox 19a (and the second gearbox 19b respectively) is arranged inside the first interface element 45a (and the second interface element 45b respectively).

[0318] Here, the first connecting element 20a (and the second connecting element 20b respectively) includes two second recesses 47. Each second recess 47 leads into the interior of the second housing portion 44 of the first connecting element 20a (and the second connecting element 20b respectively).

[0319] Here, the first end 39a and the second end 39b of the first pin 39 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are respectively housed within a first groove 46 of the first gearbox 19a (and the second gearbox 19b respectively). Furthermore, the first end 40a and the second end 40b of the second pin 40 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are respectively housed within a second groove 47 of the first connecting element 20a (and the second connecting element 20b respectively).

[0320] Therefore, the first end 39a and the second end 39b of the first pin 39 of the first torque transmission device 10a, and the first end 40a and the second end 40b of the second pin 40 of the first torque transmission device 10a slide inside the first groove 46 of the first gearbox 19a and the second groove 47 of the first connecting element 20a, respectively, i.e., are configured to slide therein.

[0321] Furthermore, the first end 39a and the second end 39b of the first pin 39 of the second torque transmission device 10b, and the first end 40a and the second end 40b of the second pin 40 of the second torque transmission device 10b slide within the first groove 46 of the second gearbox 19b and the second groove 47 of the second connecting element 20b, respectively, i.e., are configured to slide therein.

[0322] In the third embodiment, as Figure 8 and Figure 9 As shown, elements similar to those in the first and second embodiments have the same reference numerals and operate as described above. The following only describes the main differences between this third embodiment and the foregoing embodiments. In the following description, if reference numerals are used but not explicitly stated in the original text... Figure 8 and Figure 9 Reproduced in, or in Figure 8 and Figure 9 If it appears in the text but is not mentioned in the description, then it corresponds to... Figures 1 to 7 One of the objects that have the same reference numerals.

[0323] Reference Figure 8 and Figure 9The electromechanical actuator 11 according to the third embodiment of the present invention will now be described, more specifically the first torque transmission device 10a and the second torque transmission device 10b.

[0324] Here, the first torque transmission device 10a (and the second torque transmission device 10b) does not include the first transmission element 50 and the second transmission element 51.

[0325] Here, the first gearbox 19a, and in particular the first interface element 45a (and the second gearbox 19b, and in particular the second interface element 45b), includes two first openings 48. Each first opening 48 of the first gearbox 19a (and the second gearbox 19b) leads into the interior of the first housing portion 43 of the first gearbox 19a (and the second gearbox 19b).

[0326] Here, the first connecting element 20a (and the second connecting element 20b respectively) includes two second openings 49. Each second opening 49 of the first connecting element 20a (and the second connecting element 20b respectively) leads to the interior of the second housing portion 44 of the first connecting element 20a (and the second connecting element 20b respectively).

[0327] Here, the first end 39a and the second end 39b of the first pin 39 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are fixed, i.e., they are configured to be fixed (particularly in the assembly configuration of the electromechanical actuator 11) inside a first orifice 48 of the first gearbox 19a (and the second gearbox 19b respectively). Furthermore, the first end 40a and the second end 40b of the second pin 40 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are fixed, i.e., they are configured to be fixed (particularly in the assembly configuration of the electromechanical actuator 11) inside a second orifice 49 of the first connecting element 20a (and the second connecting element 20b respectively).

[0328] In particular, the first end 39a and the second end 39b of the first pin 39 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are respectively pressed into (particularly in the assembly configuration of the electromechanical actuator 11), i.e., configured to be pressed into a first orifice 48 of the first gearbox 19a (and the second gearbox 19b respectively). Furthermore, the first end 40a and the second end 40b of the second pin 40 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are respectively pressed into (particularly in the assembly configuration of the electromechanical actuator 11) a second orifice 49 of the first connecting element 20a (and the second connecting element 20b respectively).

[0329] Advantageously, the first opening 41 and the second opening 42 of the drive shaft 38 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) are both in the form of a groove.

[0330] Here, the groove is formed by two trapezoidal cross-section notches joined together at their narrowest points.

[0331] Therefore, the first opening 41 and the second opening 42 of the drive shaft 38 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) both enable a ball-and-socket connection to one of the first pin 39 and the second pin 40 of the first torque transmission device 10a (and the second torque transmission device 10b respectively) at each of the first end 38a and the second end 38b of the drive shaft 38 of the first torque transmission device 10a (and the second torque transmission device 10b respectively).

[0332] Thanks to the present invention, regardless of the embodiment, the design of the electromechanical actuator enables the transmission of torque, especially large torque, from the motor to the connecting element through the torque transmission device even when the second rotation axis of the torque transmission device is misaligned with the first rotation axis of the connecting element, especially when the misalignment is significant.

[0333] Many modifications can be made to the above embodiments without departing from the scope of the invention as defined by the claims.

[0334] In a variant not shown, the shielding device 3 includes only one movable lever, either a first movable lever 8a or a second movable lever 8b.

[0335] In a variant not shown, the shielding device 3 includes three or more movable levers, all of which can be moved by an electromechanical actuator 11, respectively via a gearbox, a torque transmission device, and possibly a clutch, a counting device, and a brake.

[0336] In a variant not shown, the first pull cord 4a, the second pull cord 4b, the third pull cord 4c, and the fourth pull cord 4d, particularly their ends, are fixed to the structure of the window or door or the wall of the building, specifically by means of a fixing element. Therefore, the shielding device 3 may not have a housing portion, i.e., a guide rail, located at or above the opening. In this case, the fixing element is configured to be fixed by fastening screws (not shown), i.e., fixed to the structure of the window or door or the wall of the building. The fastening screw passes through a through hole in the fixing element and is screwed into a plug (not shown) received in the structure of the window or door or the wall of the building, or directly screwed into the structure of the window or door or the wall of the building. Furthermore, the lengths of the first pull cord 4a, the second pull cord 4b, the third pull cord 4c, and the fourth pull cord 4d are designed to be permanently tensioned relative to the structure of the window or door or the wall of the building, so as to allow the first movable rod 8a and the second movable rod 8b to move along them. In this case, the electric drive unit 5, in particular the electromechanical actuator 11, is installed, that is, housed inside one of the movable rods 8a, 8b, especially in the assembly configuration of the shielding device 3.

[0337] In another variant not shown, the first pull cord 4a, the second pull cord 4b, the third pull cord 4c, and the fourth pull cord 4d may be kept taut by one or more elastic reset elements (e.g., one or more springs).

[0338] In one variant, the motor 16 of the electromechanical actuator 11 can be asynchronous.

[0339] In a variant not shown, the electromechanical actuator 11 further includes at least one other electric motor. Thus, the electromechanical actuator 11 includes an electric motor 16 (which may be referred to as the first electric motor) and a second electric motor, which are particularly identical. In this case, the electromechanical actuator 11 lacks the coupling device 33, as well as the first clutch 23a and the second clutch 23b. Therefore, the first electric motor 16 is configured to rotate via the first gearbox 19a and the first torque transmission device 10a, i.e., to rotate the first coupling element 20a, and the second electric motor is configured to rotate via the second gearbox 19b and the second torque transmission device 10b, i.e., to rotate the second coupling element 20b. In this case, the first assembly 22 includes the first electric motor 16 aligned along the first rotation axis Xa, and the second assembly 26 includes the second electric motor aligned along the second rotation axis Xb.

[0340] In any embodiment, one or each of the first pull rope 4a, the second pull rope 4b, the third pull rope 4c, and the fourth pull rope 4d can be replaced by a chain.

[0341] Furthermore, the embodiments and variations considered can be combined to form new embodiments of the invention without departing from the scope of the invention as defined by the claims.
