Description

DESCRIPTION

Motorized drive device for a sliding gate and closing home automation installation comprising such device

[0001] The present invention relates to a motorized driving device of a sliding gate. It also refers to a home automation installation of closure comprising a motorized drive device of this type.

[0002] In general, the present invention relates to the field of sliding gates comprising a motorized drive device that moves a gate in a sliding lateral movement, by means of an electromechanical actuator.

[0003] Motorized drive devices are known for a sliding gate comprising an electromechanical actuator and a cogwheel. The cogwheel is configured to cooperate with a frame attached to the sliding gate. The cogwheel includes an input shaft.

[0004] The electromechanical actuator comprises a housing, an electric motor, an output shaft and a decoupling mechanism. The output shaft is coupled to the electric motor. The gearwheel is configured to rotate through the output shaft of the electromechanical actuator. The housing includes a socket and a cover. The electric motor and the decoupling mechanism are mounted on the socket.

[0005] The decoupling mechanism comprises a decoupling lever, a decoupling element, a decoupling bolt and a spring. The decoupling mechanism also includes a decoupling bushing. The output shaft of the electromechanical actuator cooperates with the input shaft of the gearwheel through the decoupling bolt and the decoupling bushing. The decoupling element is carried out by means of a decoupling plate.

[0006] During the decoupling of the electromechanical actuator, an activation of the decoupling lever causes a movement of the decoupling element, then a translation movement of the decoupling bolt and a compression of the spring, in order to decouple the output shaft of the actuator electromechanical with respect to the input shaft of the sprocket.

[0007] However, these motorized drive devices have the disadvantage that, during the decoupling of the electromechanical actuator, the movement of the decoupling element is implemented by exerting a rotation movement of the decoupling element by means of the decoupling lever, arranged on one side of the electromechanical actuator.

[0008] In addition, the decoupling element, made in the form of an decoupling plate, extends towards the bottom of the housing socket, to achieve the largest decoupling plate according to the height of the electromechanical actuator. In this way, the height of the decoupling plate guarantees its rigidity.

[0009] In addition, the decoupling element, made in the form of a decoupling plate, extends towards the bottom of the housing socket, to rest on the housing socket. In this way, the support of the decoupling plate in the housing socket makes it possible to ensure that the decoupling plate is kept inside the electromechanical actuator and guarantees its displacement, depending on the activation of the decoupling lever.

[0010] After the installation of the electromechanical actuator on the ground and along the sliding gate, water and earth infiltrations occur through holes in the housing, in particular the socket, depending on the weather conditions and, consequently , come into contact with the decoupling plate, since the electromechanical actuator housing is not waterproof.

[0011] The displacement of the decoupling plate can be hindered by the deposit of mud or the insertion of grains of sand or soil and, consequently, this would lead to preventing the decoupling of the output shaft of the electromechanical actuator from the axis of cogwheel inlet

[0012] In addition, the decoupling mechanism may be damaged by the deposit of mud or the insertion of grains of sand or soil, or by infiltration of water.

[0013] In addition, in the case of water or condensation inside the electromechanical actuator housing and when the air temperature is less than or equal to zero degrees Celsius, the decoupling plate can be locked with respect to the socket of the housing by icing.

[0014] The displacement of the decoupling bushing is implemented in a rectilinear motion, that is, in the axial direction of the input shaft of the gearwheel, through the decoupling plate, while the displacement of the decoupling plate is implements in a rotation movement. Consequently, the force exerted on the decoupling bushing through the decoupling plate is implemented along an axial component but also in a radial component. In this way, the radial component of the force exerted on the decoupling bushing can cause friction and / or jams at the junction between the decoupling bushing and the decoupling plate and, therefore, a malfunction of the decoupling mechanism of the electromechanical actuator

[0015] Known sliding gate motorized drive devices also have the disadvantage of having the decoupling bushing between the decoupling element and the decoupling bolt. Therefore, the cost of obtaining the decoupling mechanism is higher due to this additional element.

[0016] Motorized driving devices of a sliding gate comprising an electromechanical actuator and a gearwheel are known from US 6108977 A, EP 2799652 A1 and US 2003/221929 A1.

[0017] More particularly, US 6 108977 A describes that the gearwheel is configured to cooperate with a chain that rotates around pulleys and whose respective axis is fixed to the sliding gate. The cogwheel includes an input shaft. The electromechanical actuator comprises a housing, an electric motor, an output shaft and a decoupling mechanism. The output shaft is coupled to the electric motor. The gearwheel is configured to rotate through the output shaft of the electromechanical actuator. The decoupling mechanism comprises a decoupling lever, a decoupling element, a decoupling bolt and a spring. The output shaft of the electromechanical actuator cooperates with the input shaft of the gearwheel through the decoupling bolt. When the electromechanical actuator is disengaged, an activation of the decoupling lever causes a movement of the decoupling element. In addition, the movement of the decoupling element causes a translation movement of the decoupling bolt and a compression of the spring, in order to decouple the output shaft of the electromechanical actuator with respect to the input shaft of the sprocket.

[0018] The present invention is intended to solve the aforementioned drawbacks and provide a motorized drive device for a sliding gate, according to claim 1, as well as a home automation installation comprising such motorized drive device, according to claim 10, which allows to guarantee the operational reliability of a decoupling mechanism and, in particular, preventing the accumulation of dirt in the decoupling mechanism and bringing it into contact with the water that infiltrates an electromechanical drive housing.

[0019] For this purpose, the present invention aims, according to a first aspect, a motorized drive device for a sliding gate comprising:

- an electromechanical actuator,

- a cogwheel, the cogwheel being configured to cooperate with a rack attached to the sliding gate, the cogwheel comprising an input shaft,

comprising the electromechanical actuator:

- a housing,

- an electric motor,

- an output shaft, the output shaft being coupled to the electric motor, the gearwheel being configured to be driven in rotation by the output shaft of the electromechanical actuator, and

- a decoupling mechanism,

comprising the decoupling mechanism:

- a decoupling lever,

- a decoupling element,

- a decoupling bolt, the output shaft of the electromechanical actuator that cooperates with the input shaft of the gearwheel through the decoupling bolt, and

- a spring.

[0020] During the decoupling of the electromechanical actuator, an activation of the decoupling lever causes a movement of the decoupling element, and the movement of the decoupling element causes a translation movement of the decoupling bolt and a compression of the spring, in order to decouple the output shaft of the electromechanical actuator with respect to the input shaft of the sprocket.

[0021] According to the invention, the decoupling element comprises:

- a first and a second branch, the first branch extending along a first side of the electric motor and the second branch extending along a second side of the electric motor,

- a first connecting element of a first end of the first branch with a first end of the second branch, the first connecting element being oriented towards the decoupling lever, and

- a second connecting element of a second end of the first branch with a second end of the second branch, the second connecting element being oriented towards the decoupling bolt.

[0022] Therefore, the operational reliability of the decoupling mechanism of the motorized drive device for a sliding gate is improved, since the decoupling element is disposed on both sides of the electric motor. This allows a balanced distribution of the sudden stresses of the decoupling mechanism parts. This also allows the decoupling element to be raised relative to a bottom wall of the electromechanical actuator housing.

[0023] In this way, the positioning of the decoupling element around the electric motor of the electromechanical actuator makes it possible to avoid the deposition of dirt in the decoupling mechanism and to put it in contact with the water that has infiltrated the electromechanical actuator housing.

[0024] Furthermore, such a decoupling mechanism makes it possible to dispense with a coupling bushing between the decoupling element and the decoupling bolt.

[0025] According to an advantageous feature of the invention, the decoupling lever is disposed on a front side of the electromechanical actuator housing, the front side of the housing being opposite one side of the housing along which the cogwheel.

[0026] According to an additional advantageous feature of the invention, during the decoupling of the electromechanical actuator, the activation of the decoupling lever causes a movement of translation of the decoupling element.

[0027] According to an additional advantageous feature of the invention, a gap is provided between the decoupling element and the bottom wall of the electromechanical actuator housing, according to the height of the electromechanical actuator.

[0028] In practice, the offset between the decoupling element and the bottom wall of the electromechanical actuator housing is in a range between 20 millimeters and 50 millimeters, and is preferably of the order of 35 millimeters.

[0029] According to an additional advantageous feature of the invention, the decoupling lever comprises a cam profile that cooperates with the first attachment element of the decoupling element, in order to displace the decoupling element.

[0030] Advantageously, the first connecting element of the decoupling element comprises a finger that rests on the cam profile.

[0031] According to an additional advantageous feature of the invention, the electromechanical actuator comprises the guiding elements in translation of the decoupling element, in the axial direction of the output axis of the electromechanical actuator.

[0032] Advantageously, a first part of the guiding elements in translation of the decoupling element cooperates with the first branch of the decoupling element. In addition, a second part of the translation guiding elements of the decoupling element cooperates with the second branch of the decoupling element.

[0033] The present invention aims, according to a second aspect, a home automation installation of closure comprising a motorized drive device for a sliding gate according to the invention, as mentioned above.

[0034] This home automation installation has similar characteristics and advantages to those described above, in relation to the motorized drive device for a sliding gate according to the invention.

[0042] The sliding gate 2 is operated in displacement by the motorized drive device 3.

[0043] The motorized drive device 3 sets the sliding gate 2 in motion between at least a first position and at least a second position, respectively corresponding to an open position and a closed position.

[0044] The motorized drive device 3 comprises an electromechanical actuator 4 that allows the sliding gate 2 to be displaced.

[0045] The motorized drive device 3 also comprises a gearwheel 5. The gearwheel 5 is configured to cooperate with a rack 23 fixed on the sliding gate 2. The gearwheel 5 comprises an input shaft 6.

[0046] The fasteners of the zipper 23 in the sliding gate 2 can be fasteners by screwing.

[0047] The fastening elements of the zipper on the sliding gate are not limiting and may be different. They may be, in particular, fasteners by elastic anchoring or riveting.

[0048] Here, the input shaft 6 is an integral part of the gearwheel 5, to form a single piece.

[0049] Alternatively, the input shaft 6 and the gearwheel 5 can be separated and formed by different parts, in particular configured to be assembled together.

[0050] The electromechanical actuator 4 of the motorized drive device 3 comprises at least one housing 7, an electric motor 8, an output shaft 9 and a decoupling mechanism 10.

[0051] The housing 7 of the electromechanical actuator 4 comprises a socket 7a and a cover 7b. The electric motor 8 of the electromechanical actuator 4 is mounted in the socket 7a of the housing 7.

[0052] Here, the socket 7a of the housing 7 is fixed on a base 11, in particular by means of screw fasteners 12.

[0053] The screw fasteners 12 comprise a plurality of fastening screws. Each fixing screw cooperates with a first subset, comprising a nut and a washer, in a wall of the socket 7a of the housing 7, and with a second subset, which comprises a nut and a washer, in a wall of the base 11 Each fixing screw passes through a passage opening 13 formed in the socket 7a of the housing 7, and then a passage opening 14 formed in the base 11. Each fixing screw cooperates with a pin 57, disposed within a block of concrete 46. The base 11 rests against the concrete block 46. The passage openings 13 formed in the socket 7a of the housing 7 are elongated in order to allow adjustment in the positioning of the socket 7a of the housing 7 with respect to base 11.

[0054] Here, the electric motor 8 is disposed within a box 45. The box 45 is mounted on the socket 7a of the housing 7 and covered by the cover 7b of the housing 7, when the cover 7b is mounted on the socket 7a.

[0055] In the embodiment illustrated in Figures 1 to 11, the housing 45 of the electric motor 8 comprises a support 47 for a pencil 48. This allows defining the fixing height of the rack 23 on the sliding gate 2 by drawing a line T in the sliding gate 2, in the assembled configuration of the home automation installation 1 and, in particular, after fixing the electromechanical actuator 4 in the base 11. This operation is shown in Figure 1 in which the pencil 48 is visible on support 47. After this operation, pencil 48 is removed from support 47.

[0056] Here, the support 47 of the pencil 48 is manufactured by means of two tabs extending from one side of the box 45, each having at its upper end a notch that forms a holding housing of the pencil 48.

[0057] In practice, the drawing of the line T is implemented in the displacement of the sliding gate 2 with respect to the electromechanical actuator 4, in a sliding lateral movement, implemented, in particular, manually and in an uncoupled position of the electromechanical actuator Four.

[0058] Here, the electric motor 8 of the electromechanical actuator 4 is arranged in a central part inside the housing 7 and, in particular, with respect to the socket 7a of the housing 7, due to the volume thereof inside the housing. the housing 7.

[0059] Advantageously, the input shaft 6 of the gearwheel 5 is supported by at least one bearing 27, in particular, two bearings 27 in the exemplary embodiment.

[0060] Here, the two bearings 27 are arranged against each other in the axial direction of the input shaft 6 of the gearwheel 5.

[0061] The socket 7a of the housing 7 comprises a housing 28 for at least one bearing 27 and, in in particular, the two bearings 27 in the exemplary embodiment. Here, the housing 28 of the socket 7a of the housing 7 is in the form of a semi-cylinder.

[0062] The electromechanical actuator 4 comprises a cover 29 that cooperates with the socket 7a of the housing 7.

[0063] The cover 29 also comprises a housing 30 for at least one bearing 27 and, in particular, the two bearings 27 in the exemplary embodiment. Here, the housing 30 of the lid 29 is in the form of a semi-cylinder.

[0064] The housing 28 of the socket 7a of the housing 7 forms a first half shell and the housing 30 of the cover 29 forms a second half shell, to enclose the bearing or the bearings 27, when the cover 29 is mounted in the socket 7a of the housing 7.

[0065] The cover 29 is fixed in the socket 7a of the housing 7 by means of fixing elements 31.

[0066] Here, the fasteners 31 of the cover 29 in the socket 7a of the housing 7 are fasteners fastened by screwing.

[0067] The fastening elements 31 by screwing comprise fixing screws and nuts, for example, in a number of two fixing screws and two nuts. Each subset of fixing screw and nut cooperates with a passage opening, not shown, arranged in the cover 29 and a passage opening 33 arranged in the socket 7a of the housing 7.

[0068] The fixing elements of the cover at the base of the housing are not limiting and may be different. They may be, in particular, fasteners by elastic anchoring.

[0069] The output shaft 9 is coupled to the electric motor 8. The gearwheel 5 is configured to rotate through the output shaft 9 of the electromechanical actuator 4.

[0070] The sliding gate 2 of the home automation installation 1 is actuated by the electromechanical actuator 4 and can be moved between the first position, open, and the second position, closed.

[0071] The motorized drive device 3 comprises an electronic control unit 15.

[0072] The electromechanical actuator 4 is controlled by the electronic control unit 15 of the motorized drive device 3.

[0073] Here, and as illustrated in Figure 8, the electronic control unit 15 of the motorized drive device 3 is disposed within the housing 7 of the electromechanical actuator 4.

[0074] The electronic control unit 15 of the motorized drive device 3 comprises hardware and / or software means. By way of non-limiting example, the hardware means may comprise at least one microcontroller.

[0075] The electronic control unit 15 of the motorized drive device 3 is capable of operating the electric motor 8 of the electromechanical actuator 4 and, in particular, allowing the electric supply of the electric motor 8.

[0076] Therefore, the electronic control unit 15 of the motorized drive device 3 controls, in particular, the electric motor 8, to open or close the sliding gate 2.

[0077] In one embodiment, the motorized drive device 15 also comprises a control interface 16, 17 operatively connected to the electronic control unit 15 of the motorized drive device 3.

[0078] As shown in Figure 1, the control interface 16, 17 is connected by a non-wired connection to the electronic control unit 15 of the motorized drive device 3.

[0079] Alternatively, the connection between the control interface 16, 17 and the electronic control unit 15 is wired.

[0080] The control interface 16, 17 comprises a control keypad provided with selection elements and possibly display elements.

[0081] By way of non-limiting examples, the selection elements may be push buttons or touch keys, The display elements may be light emitting diodes, an LCD screen (acronym for the term "liquid crystal display") or TFT (acronym for the term "thin film transistor").

[0082] The control interface 16, 17 allows a user to adjust the parameters and / or control the motorized drive device 3 and, in particular, the electromechanical actuator 4 associated with the sliding gate 2, by means of a support in one of the selection elements.

[0083] The control interface 16, 17 may include, for example, a local control unit 16, which includes a remote control.

[0084] The local control unit 16 can be connected, in wired or wireless connection, with a central control unit 17.

[0085] The electronic control unit 15, the local control unit 16 or the central control unit 17 may be in communication with a weather station located in or near a land delimited by the fence and including, in particular, one or more sensors that can be configured to determine, for example, a temperature, a wind speed or even a brightness. When the opening is provided in an enclosure or a building, this weather station is taken out of this enclosure or building.

[0086] The electronic control unit 15 also comprises an order receiving module, in particular radio orders issued by an order emitter, such as the remote control 16 intended to control the electromechanical actuator 4. The reception module for Orders can also allow the reception of cable-transmitted orders.

[0087] The motorized drive device 3 is configured to execute the opening or closing commands of the sliding gate 2 of the home automation installation 1, which can be transmitted via the control interface 16, 17.

[0088] It is now described, with reference to Figures 2 to 11, the decoupling mechanism 10 of the electromechanical actuator 4.

[0089] The decoupling mechanism 10 of the electromechanical actuator 4 comprises at least one decoupling lever 18, a decoupling element 19, a decoupling bolt 20 and a spring 21.

[0090] In the first embodiment, shown in Figures 2 to 11, the decoupling lever 18 is accessible by removing the cover 7b from the housing 7 with respect to the socket 7a of the housing 7.

[0091] In practice, the removal of the socket 7b from the housing 7 with respect to the socket 7a of the housing 7 is implemented by disassembling the fasteners 49.

[0092] Here, the fixing elements 49 of the cover 7b of the housing 7 in the socket 7a of the housing 7 are fastening elements by screwing.

[0093] The fasteners 49 by screwing comprise fasteners, for example, two, which cooperate respectively with a passage opening 50 formed in the cover 7b of the housing 7 and a screw shank 51 formed in the socket 7a of the housing 7.

[0094] The fixing elements of the housing cover in the housing socket are not limiting and may be different. They may be, in particular, fasteners by elastic anchoring.

[0095] The output shaft 9 of the electromechanical actuator 4 cooperates with the input shaft 6 of the gearwheel 5 by means of the decoupling bolt 20.

[0096] During the decoupling of the electromechanical actuator 4 of the motorized drive device 3, an activation of the decoupling lever 18 causes a movement of the decoupling element 19. In addition, the movement of the decoupling element 19 causes a movement of the bolt translation of decoupling 20 and a compression of the spring 21, in order to decouple the output shaft 9 of the electromechanical actuator 4 with respect to the input shaft 6 of the gearwheel 5.

[0097] Therefore, during the decoupling of the electromechanical actuator 4 of the motorized drive device 3, the activation of the decoupling lever 18 allows the output shaft 9 of the electromechanical actuator 4 to be released in rotation with respect to the input shaft 6 of the cogwheel 5.

[0098] Thus, during decoupling of the electromechanical actuator 4 of the device motorized drive 3, the electromechanical actuator 4 is held in position with respect to the base 11 and, in particular, does not move with respect to the sliding gate 2 or with respect to the base 11.

[0099] Similarly, during decoupling of the electromechanical actuator 4 of the motorized drive device 3, the gearwheel 5 is held in position with respect to the rack 23 and, in particular, does not move with respect to the sliding gate 2 or with respect to the zipper 23.

[0100] Therefore, the decoupling of the electromechanical actuator 4 of the motorized drive device 3 is only implemented by actuating the decoupling lever 18, to decouple the output shaft 9 of the electromechanical actuator 4 with respect to the input shaft 6 of the wheel toothed 5.

[0101] In this way, the user quickly and easily implements the decoupling of the electromechanical actuator 4 from the motorized drive device 3.

[0102] Advantageously, the activation of the decoupling lever 18 is implemented in a rotational movement around an axis of rotation X22.

[0103] Therefore, the decoupling lever 18 can rotate freely around the axis of rotation X22.

[0104] Here, the socket 7a of the housing 7 defines the axis of rotation X22. The rotation axis X22 is defined in the socket 7a of the housing 7 in the form of a pin 22. The decoupling lever 18 is held axially on the pin 22 by means of a fixing screw 22a that cooperates with a screwed-in rod arranged in the center of the pin 22.

[0105] In the exemplary embodiment shown in Figures 1 to 11, the input shaft 6 of the gearwheel 5 is a hollow shaft.

[0106] Therefore, the input shaft 6 of the gearwheel 5 comprises a longitudinal housing 24.

[0107] In addition, the spring 21 is disposed inside the housing 24 of the input shaft 6 of the gearwheel 5.

[0108] Here, spring 21 is a spiral spring.

[0109] Advantageously, the output shaft 9 of the electromechanical actuator 4 cooperates axially with the input shaft 6 of the gearwheel 5.

[0110] In addition, the input shaft 6 of the gearwheel 5 comprises a groove 25 cooperating with the decoupling bolt 20. And the output shaft 9 of the electromechanical actuator 4 comprises a groove 26 cooperating with the decoupling bolt 20 .

[0111] When the decoupling lever 18 is in the rest position, in other words, of engagement, the decoupling bolt 20 is supported on the output shaft 9 of the electromechanical actuator 4, by means of the force exerted by the spring 21. And the decoupling bolt 20 is in contact with the input shaft 6 of the gearwheel 5, being coupled, on the one hand, in the groove 26 of the output shaft 9 of the electromechanical actuator 4 and, on the other hand, in the groove 25 of the input shaft 6 of the gearwheel 5.

[0112] Therefore, by placing the decoupling lever 18 in the rest position, the output shaft 9 of the electromechanical actuator 4 is coupled with the input shaft 6 of the gearwheel 5, by means of the intermediate bolt decoupling 20 subject to the action of spring 21 and coupled simultaneously in slots 25 and 26.

[0113] In this case, during the activation of the electric motor 8, the output shaft 9 of the electromechanical actuator 4 rotates the input shaft 6 of the gearwheel 5, through the decoupling bolt 20.

[0114] When the decoupling lever 18 is in the decoupling position, the decoupling element 19 rests on the decoupling bolt 20, to push the decoupling bolt 20 towards the sprocket 5 and compress the spring 21. The bolt 21 decoupling 20 remains in contact with the input shaft 6 of the gearwheel 5. More precisely, the decoupling bolt 20 remains integrally rotatably connected to the input shaft 6 of the gearwheel 5, since it remains engaged in the groove 25 On the other hand, when pushed by the decoupling element 19, the decoupling bolt 20 is removed from the groove 26 of the output shaft 9 of the electromechanical actuator 4, so that the decoupling bolt 20 is no longer integral in rotation with the output shaft 9.

[0115] Therefore, by placing the decoupling lever 18 in the disengaged position, the output shaft 9 of the electromechanical actuator 4 is disengaged from the input shaft 6 of the gearwheel 5, by means of the element decoupling 19 and decoupling bolt 20.

[0116] Here, the decoupling element 19 is a slider.

[0117] The decoupling element 19 comprises a first and a second branch 34, 35. In the assembled configuration of the electromechanical actuator 4, the first branch 34 extends along a first side of the electric motor 8 and the second branch 35 it extends along a second side of the electric motor 8.

[0118] Here, the first side of the electric motor 8 is opposite the second side of the electric motor 8, with respect to the axis of rotation XX of the output shaft 9 of the electromechanical actuator 4. The axis XX is also the axis of rotation of the axis input 6 of the gearwheel 5.

[0119] In other words, the first side of the electric motor 8 extends from the output shaft 9 of the electromechanical actuator 4 to a first side 58 of the housing 7. In addition, the second side of the electric motor 8 extends from the shaft output 9 of the electromechanical actuator 4 to a second side 59 of the housing 7. The first side 58 of the housing 7 is opposite the second side 59 of the housing 7, with respect to the vertical plane P passing through the axis of rotation XX of the output shaft 9 of the electromechanical actuator 4 and the input shaft 6 of the gearwheel 5, as shown in Figure 11.

[0120] The decoupling element 19 comprises a first joint element 36 of a first end of the first branch 34 with a first end of the second branch 35. The first connection element 36 is oriented towards the decoupling lever 18.

[0121] In addition, the decoupling element 19 comprises a second joint element 37 of a second end of the first branch 34 with a second end of the second branch 35. The second connection element 37 is oriented towards the disengagement bolt 20 .

[0122] Here, the first and second connecting elements 36, 37 are made by means of branches of the decoupling element 19. These branches of the separation element 19 forming the first and second joining elements 36, 37 are arranged in a direction perpendicular to the axis of rotation XX of the output shaft 9 of the electromechanical actuator 4 and the input shaft 6 of the gearwheel 5.

[0123] In addition, the branches of the decoupling element 19 forming the first and second connecting elements 36, 37 are connected respectively to the first and second branches 34, 35 of the decoupling element 19.

[0124] The operational reliability of the decoupling mechanism 10 of the motorized driving device 3 of the sliding gate 2 is improved, since the decoupling element 19 is arranged on both sides of the electric motor 8. This allows a balanced distribution of the forces Sudden parts of the decoupling mechanism 10. This also makes it possible to raise the decoupling element 19 with respect to a bottom wall 38 of the housing 7 of the electromechanical actuator 4, in particular of a bottom wall 38 of the socket 7a of the housing 7.

[0125] In this way, the positioning of the decoupling element 19 around the electric motor 8 of the electromechanical actuator 4 allows to avoid the deposition of dirt in the decoupling mechanism 10 and to put it in contact with the water that has infiltrated the housing 7 of the electromechanical actuator 4.

[0126] In addition, such a decoupling mechanism 10 makes it possible to dispense with a decoupling bushing between the decoupling element 19 and the decoupling bolt 20.

[0127] Furthermore, such an arrangement of the decoupling element 19 makes it possible to increase the design possibilities of the housing 7 of the electromechanical actuator 4.

[0128] A vertical offset D is provided between the decoupling element 19, in particular a lower edge 44 of the decoupling element 19, and the bottom wall 38 of the housing 7 of the electromechanical actuator 4, in particular the bottom wall 38 of the socket 7a of the housing 7, according to the height H of the electromechanical actuator 4, as shown in Figures 5 and 11.

[0129] Advantageously, the offset D between the decoupling element 19 and the bottom wall 38 of the housing 7 of the electromechanical actuator 4 is in a range that extends between 20 millimeters and 50 millimeters. The offset D is preferably of the order of 35 millimeters.

[0130] Therefore, the offset D is determined to prevent the deposit of dirt in the decoupling mechanism 10 and its contact with water that has infiltrated the housing 7 of the electromechanical actuator 4.

[0131] The joining of each of the first and second branches 34, 35 of the decoupling element 19, on the one hand, to the first joint element 36 of the decoupling element 19 and, on the other hand, to the second joint element 37 , allows to guarantee the rigidity of the decoupling element 19.

[0132] Preferably, the decoupling lever 18 is disposed on a front side 39 of the housing 7 of the electromechanical actuator 4, the front side 39 of the housing 7 being opposite to a side 40 of the housing 7 along which has the cogwheel 5.

[0133] Therefore, the accessibility of the decoupling lever 18 is facilitated.

[0134] Advantageously, during the decoupling of the electromechanical actuator 4 of the motorized actuation device 3, the activation of the decoupling lever 18 causes a translation movement of the decoupling element 19.

[0135] The translation displacement of the decoupling element 19, during the activation of the decoupling lever 18, allows to achieve an axial thrust in the decoupling bolt 20, to disengage it in rotation of the output shaft 9, which limits the restrictions in the decoupling mechanism 10 and guarantees the reliability of its operation.

[0136] In practice, the decoupling lever 18 comprises a cam profile 41 that cooperates with the first connecting element 36 of the decoupling element 19.

[0137] Here, the first connecting element 36 of the decoupling element 19 comprises a finger 32 which rests on the cam profile 41.

[0138] Advantageously, the cam profile 41 of the decoupling lever 18 comprises an area corresponding to an uncoupled position of the decoupling mechanism 10.

[0139] Here, the cam profile 41 of the decoupling lever 18 comprises a concavity 55 corresponding to the decoupled position of the decoupling mechanism 10, when the finger 32 is resting against the concavity 55.

[0140] In the embodiment illustrated in Figures 1 to 11, the decoupling element 19 is made in one piece. In such a case, the only piece that forms the decoupling element 19 comprises the first and second branches 34, 35, as well as the first and second joining elements 36, 37.

[0141] In another embodiment, not shown, the decoupling element 19 is made in two parts. In such a case, the first part of the decoupling element 19 may comprise the first and second branches 34, 35, as well as the first joint element 36 of the first and second branches 34, 35 oriented to the decoupling lever 18. The second part of the decoupling element 19 can then comprise the second connecting element 37 of the first and second branches branches 34, 35 oriented towards the decoupling bolt 20.

[0142] In addition, the second part of the decoupling element 19 can be made by means of a plate.

[0143] Advantageously, the second connecting element 37 of the decoupling element 19 comprises a through hole 42 of the output shaft 9 of the electromechanical actuator 4.

[0144] Therefore, the output shaft 9 of the electromechanical actuator 4 extends through the through hole 42 of the second joint element 37 of the decoupling element 19, to allow translation displacement of the decoupling element 19, to the activate the decoupling lever 18.

[0145] To do this, the diameter of the passage hole 42 of the second joint element 37 of the decoupling element 19 is larger than the diameter of the output shaft 9 of the electromechanical actuator 4.

[0146] In practice, the second joint element 37 of the decoupling element 19 comprises a wall 43 cooperating with at least one end 20a of the decoupling bolt 20, in particular with the two ends 20a of the decoupling bolt 20 arranged one on top of the other, in the same vertical plane.

[0147] In addition, the decoupling bolt 20 comprises a wall 20b that cooperates, on the one hand, with the groove 26 of the output shaft 9 of the electromechanical actuator 4, when the decoupling lever 18 is in the rest position, in others words, in disengagement, and, on the other hand, with the groove 25 of the input shaft 6 of the gearwheel 5, regardless of the position of the decoupling lever 18.

[0148] In the exemplary embodiment illustrated in Figures 1 to 11, the groove 26 of the output shaft 9 of the electromechanical actuator 4 is formed in a part of the axial length of the output shaft 9. The wall 20b of the decoupling bolt 20 is in contact with the bottom of the groove 26, during the displacement of the wall 20b of the decoupling bolt 20 inside the groove 26 of the output shaft 9 of the electromechanical actuator 4. Furthermore, the groove 25 of the input shaft 6 of the gearwheel 5 is provided in a part of the axial length of the input shaft 6.

[0149] Here, the decoupling bolt 20 has a U-shape.

[0150] Preferably, the electromechanical actuator 4 comprises guiding elements 56 in translation of the decoupling element 19, in the axial direction of the output shaft 9 of the electromechanical actuator 4, that is, parallel to the axis XX.

[0151] Therefore, the movement of the decoupling element 19 is guided in translation in the axial direction of the output shaft 9 of the electromechanical actuator 4, depending on the activation of the decoupling lever 18, in particular its rotation in around the axis of rotation X22.

[0152] Advantageously, a first part of the guiding elements 56 in translation of the decoupling element 19 cooperates with the first branch 34 of the decoupling element 19. And a second part of the guiding elements 56 in translation of the decoupling element 19 cooperates with the second branch 35 of the decoupling element 19.

[0153] Therefore, the decoupling element 19 is guided in translation in its first branch 34, as well as in its second branch 35 by the guide elements 56.

[0154] In practice, the first part of the guiding elements 56 is arranged on the first side of the electric motor 8, to cooperate with the first branch 34 of the decoupling element 19 arranged on the first side of the electric motor 8, and the second part of the guiding elements 56 is arranged on the second side of the electric motor 8, to cooperate with the second fork 35 of the decoupling element 19 arranged on the second side of the electric motor 8.

[0155] Advantageously, each guiding element 56 comprises a guiding surface that cooperates with a side wall of the first branch 34 or the second branch 35 of the decoupling element 19.

[0156] In addition, each guiding element 56 comprises a support surface cooperating with a bottom wall of the first branch 34 or the second branch 35 of the decoupling element 19.

[0157] Therefore, the decoupling element 19 is supported on its first branch 34, as well as on its second branch 35 by the guiding elements 56.

[0158] In addition, the support surface of each guide element 56 makes it possible to guarantee the vertical offset D between the decoupling element 19 and the bottom wall 38 of the housing 7 of the electromechanical actuator 4.

[0159] Here, the guiding elements 56 in translation of the decoupling element 19 are tabs provided in the socket 7a of the housing 7. Each tongue formed in the socket 7a of the housing 7 has a cutout, to form the guiding surface and the support surface.

[0160] In the exemplary embodiment, the first part of the guiding elements 56 comprises two tabs formed in the socket 7a of the housing 7, and the second part of the guiding elements 56 comprises two tabs formed in the socket 7a of the housing 7.

[0161] The number of tabs that form the first part of the guiding elements or the second part of the guiding elements is not limiting and may be different, in particular greater than two.

[0162] In the second embodiment, illustrated in Figures 12 to 15, elements similar to those of the first embodiment bear the same references. The following describes mainly what distinguishes this embodiment from the previous one. In this embodiment, the decoupling lever 18 can be accessed by moving a hatch 52 with respect to the housing 7.

[0163] Here, the trapdoor 52 is articulated with respect to the socket 7a of the housing 7.

[0164] Advantageously, the opening or closing of the hatch 52 with respect to the housing 7 is implemented according to a rotation movement around a rotation axis 54.

[0165] Therefore, the hatch 52 can rotate freely around the axis of rotation 54.

[0166] Here, the socket 7a of the housing 7 defines the axis of rotation 54 of the trapdoor 52. This axis of rotation 54 is made in the form of a pin. The trapdoor 52 is held axially on the rotation axis 54 by means of a fixing screw that cooperates with a screw rod arranged in the center of the rotation axis 54.

[0167] In addition, the trapdoor 52 comprises a locking element, not shown.

[0168] Therefore, the hatch 52 is held in position against the housing 7, in a locked position. In addition, the trapdoor 52 can be moved relative to the housing 7, in an unlocked position.

[0169] Here, the trap door locking element 52 is an elastic interlocking element, in particular an elastic interlocking flange, which cooperates with a housing formed in the socket 7a of the housing 7.

[0170] In practice, the trapdoor locking element 52 is actuated by means of a tool 53, to tilt the trapdoor 52 from the locked position to the unlocked position.

[0171] In this embodiment, the trapdoor 52 comprises an insertion groove of the tool 53, to allow the tool 53 to come into contact with the locking element of the trapdoor 52.

[0172] In addition, the tool 53 comprises a notch that cooperates with the elastic locking tongue that forms the locking element of the trapdoor 52.

[0173] The notch of the tool 53 prevents the unlocking of the elastic interlocking tab that forms the locking element of the trapdoor 52 by a means to the tool 53, so that the opening of the trapdoor 52 can only be implemented at through tool 53.

[0174] Here, the trapdoor locking element 52 is activated by a rotating movement, in particular from the top to the bottom of the tool 53, in the assembled configuration of the electromechanical actuator 4 at the base 11, and, more particularly, at a predetermined angle, which may be, for example, of the order of 36 °.

[0175] In this case, the decoupling lever 18 can be accessed without having to remove the cover 7b of the housing 7 with respect to the socket 7a of the housing 7.

[0176] In addition, the fasteners of the cover 7b of the housing 7 in the socket 7a of the housing 7 of this embodiment may be identical to those of the first embodiment, illustrated in Figures 2 and 3.

[0177] For the rest, the device of this second embodiment functions as that of the first embodiment, in particular in its decoupling element, its decoupling bolt and its spring, which are similar to those of the first embodiment and which are not shown in figures 12 to 15.

[0178] Thanks to the present invention and regardless of the embodiment, the operational reliability of the decoupling mechanism of the motorized drive device for a sliding gate is improved, since the decoupling element is arranged on both sides of the electric motor. This allows a balanced distribution of the sudden stresses of the decoupling mechanism parts. This also allows the decoupling element to be raised relative to a bottom wall of the electromechanical actuator housing.

[0179] In this way, the positioning of the decoupling element around the electric motor of the electromechanical actuator makes it possible to avoid the deposition of dirt in the decoupling mechanism and to put it in contact with the water that has infiltrated the electromechanical actuator housing.

[0180] Many modifications can be made to the embodiments described above without departing from the scope of the invention defined by the claims.

[0181] In addition, the intended embodiments and variants may be combined to generate new embodiments of the invention, without departing from the scope of the invention defined by the claims.
