Description

Title of the invention: Motorized drive device for a concealment device and associated concealment device

[0001] The present invention relates to a motorized drive device for a screening device, in other words a motorized drive device for a screening device. This motorized drive device is provided, in other words is configured, to move at least one screen.

[0002] The present invention also relates to a concealment device equipped with such a motorized drive device.

[0003] Generally, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and at least a second position.

[0004] Document WO 2020 / 099628 A1 is already known, which describes a motorized drive device for a concealment device. The motorized drive device comprises a housing, a motorization block and an electronic control unit. The housing comprises a cavity and an opening. The electronic control unit comprises a printed circuit board and an electrical connection device. The electrical connection device is accessible through the opening of the housing, in an assembled configuration of the motorized drive device. The electrical connection device comprises electrical connection points. The electrical connection points are provided on one face of the printed circuit board. In addition, the motorized drive device comprises a switching device. The switching device is configured to close the opening of the housing. The switching device is removable from the housing.Furthermore, this document WO 2020 / 099628 A1 describes that, following a withdrawal of the switching device from the housing, a socket of a terminal can be positioned at the opening of the housing of the motorized drive device, so that electrical connection points of the electrical connection device are configured to be electrically connected to electrical connection pins of the socket of the terminal. This motorized drive device is generally satisfactory.

[0005] However, this motorized drive device has the disadvantage that the switching device is surface-mounted on the housing opposite the opening thereof and that the terminal socket is also surface-mounted in place of the switching device, following removal of the switching device.

[0006] Thus, the electrical outlet of the terminal is not configured to be housed inside from the housing cavity to replace one of the components of the motorized drive device, since, following removal of the switching device by dismantling fixing elements, the electrical connection device is only accessible through the opening of the housing from outside the housing by positioning the terminal socket resting against the housing.

[0007] Furthermore, the electrical connection pins are stationary relative to the terminal socket, i.e. are not movable relative to the terminal socket.

[0008] Thus, the electrical connection pins cannot be moved relative to the terminal socket by means of a mechanism integrated into the socket to be brought into contact with the electrical connection points of the electrical connection device provided on one face of the printed circuit board, which itself is housed inside the housing of the motorized drive device.

[0009] Therefore, the electrical connection pins of the terminal socket and / or the electrical connection points of the electrical connection device may be damaged when brought into contact with each other, due to the pressure exerted by the electrical connection pins on the electrical connection points.

[0010] Furthermore, the positioning of the terminal socket opposite the opening of the housing of the motorized drive device requires additional positioning and / or fixing elements at the housing which are visible from the outside of the housing.

[0011] The present invention aims to solve the aforementioned drawbacks and to propose a motorized drive device for a concealment device, as well as a concealment device comprising such a motorized drive device, making it possible to facilitate and guarantee the electrical contacting of electrical connection pins of a connection module with electrical connection points of a printed circuit board of an electronic control unit of the motorized drive device, while limiting the risk of damage to the electrical connection pins and the electrical connection points.

[0012] To this end, the present invention aims, according to a first aspect, at a motorized drive device for a concealment device,

[0034] Thus, such a construction of the motorized drive device makes it possible to facilitate and guarantee the electrical contacting of the first electrical connection pins of the connection module with the electrical connection points of the electrical connection device of the electronic control unit of the motorized drive device, following the replacement of the complementary member by the connection module inside the housing of the motorized drive device, while limiting the risk of damage to the electrical connection pins and the electrical connection points.

[0035] In this way, during a maintenance or repair intervention of the motorized drive device, the connection module is housed inside the housing cavity in place of the complementary member, so as to access, via the connection module, the electrical connection device of the electronic control unit of the motorized drive device.

[0036] Consequently, following the withdrawal of the complementary member from the cavity of the housing, the connection module is electrically connected to the electrical connection device of the electronic control unit of the motorized drive device, by inserting the connection module through the first opening provided in the housing of the motorized drive device, given that the complementary member no longer closes this first opening of the housing, then by moving the first electrical connection pins between the retracted position and the projected position.

[0037] Furthermore, the placement of the connection module inside the cavity of the housing in place of the complementary member makes it possible to dispense with positioning and / or fixing elements provided in the housing other than those intended for the assembly of the complementary member with the housing.

[0043] According to another advantageous characteristic of the invention, the first printed circuit board of the electronic control unit extends inside the housing and parallel to the direction of movement of the connection module inside the cavity of the housing.

[0044] According to another advantageous characteristic of the invention, the complementary member comprises first retaining elements. The housing further comprises second retaining elements. When the complementary member is housed inside the cavity of the housing, each first retaining element of the complementary member is configured to cooperate with one of the second retaining elements of the housing, so as to hold the complementary member in position inside the housing.

Furthermore, when the connection module is housed inside the cavity of the housing, as a replacement for the complementary member, each third retaining element of the connection module is configured to cooperate with one of the second retaining elements of the housing, so as to hold the connection module in position inside the housing.

[0250] In the assembled configuration of the occulting device 3, when the electric motor 11 is electrically activated, the drive wheel 13 is pressed against the rod 4, by means of the elastic return elements 44 bearing on the first support wall 52 arranged in the housing 43 and is driven in rotation, around the first axis of rotation XI3, by means of the electric motor 11 and, possibly, of the transmission device 28.

[0251] Thus, a compression force is exerted on the elastic return elements 44 causing a movement of the motorization block 49 inside the housing 43. This movement of the motorization block 49 inside the housing 43 depends on the direction of rotation of the electric motor 11 and, therefore, of the drive wheel 13.

[0252] In this way, the motorization block 49 is in an inclined position inside the housing 43 and, more particularly, relative to the rod 4.

[0253] Consequently, an arching is generated inside the motorized drive device 10 causing an increase in the force of the drive wheel 13 on the rod 4, so as to move the motorized drive device 10 along the rod 4.

[0254] Advantageously, when the electric motor 11 is electrically deactivated, the motorization block 49 can be in a position where a median plane of this motorization block 49 is parallel to the median plane P of the housing 43, in practice superimposed on the median plane P.

[0255] As a variant, not shown, when the electric motor 11 is electrically deactivated, the motorization unit 49 can remain in an inclined position relative to the median plane P of the housing 43, in particular due to the force of the drive wheel 13 on the first surface 5 of the rod 4, in particular in the assembled configuration of the occulting device 3, and following a movement of the motorized drive device 10 along the rod 4.

[0256] In the assembled configuration of the occulting device 3, when the electric motor 11 is electrically deactivated, the drive wheel 13 is pressed against the rod 4, by means of the elastic return elements 44 bearing on the housing 43 and, more particularly, on the first support wall 52.

[0257] Thus, a force is exerted in a balanced manner on the elastic return elements 44. This force is transmitted to the housing 43, to the wall 9 then transmitted to the first and second holding devices 37, 39 which themselves transmit this force to the rod 4.

[0258] In this way, the motorization block 49 can be in a vertical position inside the housing 43 and, more particularly, relative to the rod 4 which, by hypothesis, is horizontal.

[0259] Advantageously, the housing 43 is configured to be held, in other words is held, in a predetermined orientation, in particular constant over time, relative to the rod 4, by means of the first and second holding devices 37, 39, in particular in the assembled configuration of the concealing device 3.

[0260] Thus, this predetermined orientation of the housing 43 relative to the rod 4 is implemented following the maintenance of the motorized drive device 10 relative to the rod 4 by means of the first and second maintenance devices 37, 39 cooperating with the rod 4, whether during the electrical deactivation of the electric motor 11 or during the electrical activation of the electric motor 11.

[0261] In this way, an angle value, not shown, between the median plane P of the housing 43 relative to the longitudinal axis A4 of the rod 4 is constant, whether when the motorized drive device 10 is stopped relative to the rod 4 or when the motorized drive device 10 is moving along the rod 4, implemented by the electrical activation of the electric motor 11.

[0262] Preferably, the angle value between the median plane P of the housing 43 relative to the longitudinal axis A4 of the rod 4 is of the order of 90°.

[0263] Such a construction of the motorized drive device 10 makes it possible to minimize a stiffness value of the or each elastic return element 44.

[0264] Due to the maintenance of the motorized drive device 10 relative to the rod 4 by means of the first and second maintenance devices 37, 39, the stiffness value of the elastic return element(s) 44 determines an initial contact pressure of the drive wheel 13 on the rod 4, as long as the electric motor 11 is electrically deactivated.

[0265] The power supply unit 40 and an electrical connection device 57 of the motorized drive device 10, illustrated in FIGS. 1 to 7, as well as a module of connection 61 also belonging to the motorized drive device 10.

[0266] Here, the motorized drive device 10 further comprises the connection module 61.

[0267] The connection module 61 comprises a chassis 63.

[0268] Here, the chassis 63 of the connection module 61 has a similar general shape to that of the 40 power supply.

[0269] The connection module 61 further comprises first electrical connection pins 62.

[0270] The connection module 61 further comprises a displacement mechanism 67. Furthermore, the displacement mechanism 67 is configured to move, in other words displace, the first electrical connection pins 62 of the connection module 61 relative to the chassis 63, between a retracted position and a projected position and between the projected position and the retracted position.

[0271] The displacement mechanism 67 may also be referred to as the projection and retraction mechanism or the protrusion and retraction mechanism. The retracted position may also be referred to as the retraction position. In addition, the projected position may also be the deployed position or the protrusion position.

[0272] When the connection module 61 is housed inside the cavity 14 of the housing 43, the movement of the first electrical connection pins 62 between the retracted position and the projected position causes the electrical connection between the electrical connection points 60 and the first electrical connection pins 62 in the projected position. In other words, when the connection module 61 is housed inside the cavity 14 of the housing 43, the electrical connection points 60 of the electrical connection device 57 are configured to be electrically connected, in other words are electrically connected, to the first electrical connection pins 62 of the connection module 61 in the projected position.

[0273] The electronic control unit 17 further comprises the electrical connection device 57. The electrical connection device 57 is accessible, in other words is configured to be accessible, through the first opening 42 of the housing 43, in particular in the assembled configuration of the motorized drive device 10.

[0274] The electrical connection device 57 comprises at least electrical connection points 60. The electrical connection points 60 are provided on a face 26A of the first printed circuit board 26.

[0275] The cavity 14 of the housing 43 is configured to receive, in other words receives, selectively the power supply unit 40, the power supply unit 40 then being housed inside the cavity 14 of the housing 43, and the connection module 61, the connection module 61 then being housed inside the cavity 14 of the housing 43, replacing the power supply unit 40, following removal of the power supply unit 40 by relative to the housing 43, through the first opening 42 of the housing 43, so that the electrical connection points 60 of the electrical connection device 57 are configured to be electrically connected to the first electrical connection pins 62 of the connection module 61, in the projected position of the first electrical connection pins 62 relative to the chassis 63.

[0276] It is understood that the cavity 14 of the housing 43 is, in particular in the assembled configuration of the motorized drive device 10, configured to receive, in other words receives, either the power supply unit 40 in the absence of the connection module 61, as described above, or the connection module 61 as a replacement for the power supply unit 40, as described just above.

[0277] Thus, the construction of the motorized drive device 10 makes it possible to facilitate and guarantee the electrical contacting of the first electrical connection pins 62 of the connection module 61 with the electrical connection points 60 of the electrical connection device 57 of the electronic control unit 17 of the motorized drive device 10, following the replacement of the power supply unit 40 by the connection module 61 inside the housing 43 of the motorized drive device 10, in particular without having to disassemble the motorized drive device 10 with respect to the occulting device 3, while limiting the risk of damage to the electrical connection pins 62 and the electrical connection points 60.

[0278] In this way, during a maintenance or repair intervention on the motorized drive device 10, the connection module 61 is housed inside the cavity 14 of the housing 43 in place of the power supply unit 40, so as to access, via the connection module 61, the electrical connection device 57 of the electronic control unit 17 of the motorized drive device 10.

[0279] Consequently, following the withdrawal of the power supply unit 40 from the cavity 14 of the housing 43, the connection module 61 is electrically connected to the electrical connection device 57 of the electronic control unit 17 of the motorized drive device 10, by inserting the connection module 61 through the first opening 42 provided in the housing 43 of the motorized drive device 10, given that the power supply unit 40 no longer closes this first opening 42 of the housing 43, then by moving the first electrical connection pins 62 between the retracted position and the projected position.

[0280] Furthermore, the displacement mechanism 67 makes it possible to avoid damaging the first electrical connection pins 62, as well as the electrical connection points 60, during insertion or removal of the connection module 61 relative to the cavity 14 of the housing 43.

[0281] Furthermore, the installation of the connection module 61 inside the cavity 14 of the housing 43 in place of the power supply unit 40 makes it possible to dispense with positioning and / or fixing elements provided in the housing 43 other than those intended for assembling the power supply unit 40 with the housing 43.

[0282] Advantageously, the connection module 61 is configured to be connected, in other words is connected, to a terminal 68, by means of a link L, as illustrated in [Fig.8].

[0283] The terminal 68 may be, for example, a configuration tool, the local control unit 15 or the central control unit 16. The terminal 68 may also be a smartphone, a tablet or a computer.

[0284] Here, the connection L between the connection module 61 and the terminal 68 is implemented via a first cable 69 and a second cable 81. The first cable 69 is configured to allow communication between the terminal 68 and the connection module 61, preferably bidirectionally. Furthermore, the second cable 81 is configured to supply electrical energy to the connection module 61 from the terminal 68.

[0285] Thus, the terminal 68 is configured to communicate with the electronic control unit 17 of the motorized drive device 10 by means of the connection module 61, following the electrical connection of the terminal 68 with the connection module 61 via the first cable 69 and following the electrical connection of the connection module 61 with the electrical connection device 57 via the first electrical connection pins 62 and the electrical connection points 60.

[0286] In this way, the communication between the electronic control unit 17 of the motorized drive device 10, the connection module 61 and the terminal 68 is implemented in a wired manner.

[0287] Furthermore, the terminal 68 is configured to supply electrical energy to the connection module 61, following the electrical connection of the terminal 68 with the connection module 61 via the second cable 81.

[0288] Advantageously, the terminal 68 is configured to supply electrical energy to the electronic control unit 17 of the motorized drive device 10 by means of the connection module 61, following the electrical connection of the terminal 68 with the connection module 61 via the second cable 81 and following the electrical connection of the connection module 61 with the electrical connection device 57 via the first electrical connection pins 62 and the electrical connection points 60.

[0289] As a variant, not shown, the link L between the connection module 61 and the terminal 68 is implemented via a single cable. This single cable is configured to allow communication between the terminal 68 and the module connection 61, preferably bidirectionally, and, optionally, is configured to supply electrical energy to the connection module 61 and, optionally, to the electronic control unit 17 of the motorized drive device 10 from the terminal 68.

[0290] As a variant, not shown, the link L between the connection module 61 and the terminal 68 is implemented via an exchange of signals, in particular radio or optical. Furthermore, the connection module 61 and the terminal 68 respectively comprise a communication module, for transmitting and / or receiving signals. The exchange of signals can be implemented according to a communication protocol, which can be, for example, Wifi, Bluetooth or proprietary. Thus, the terminal 68 is configured to communicate with the electronic control unit 17 of the motorized drive device 10 by means of the connection module 61, following the pairing of the terminal 68 with the connection module 61 and the electrical connection of the connection module 61 with the electrical connection device 57 via the first electrical connection pins 62 and the electrical connection points 60.In this way, the communication between the electronic control unit 17 of the motorized drive device 10 and the connection module 61 is implemented in a wired manner and the communication between the connection module 61 and the terminal 68 is implemented in a wireless manner.

[0291] Advantageously, the electrical connection device 57 is configured to reset or adjust at least part of the operating parameters of the motorized drive device 10, by means of the terminal 68 via the connection module 61, the operating parameters being stored by the memory of the microcontroller 18 of the electronic control unit 17.

[0292] Here, the operating parameters may be, for example, a movement speed of the screen 2 or the upper or lower end position of the screen 2.

[0293] Advantageously, the electrical connection device 57 is configured to allow a diagnosis of the motorized drive device 10, from operating data of the motorized drive device 10, by means of the terminal 68 via the connection module 61, the operating data being stored by the memory of the microcontroller 18 of the electronic control unit 17.

[0296] Here, the electrical conductors of the first printed circuit board 26 correspond to electrical tracks printed on the first printed circuit board 26.

[0297] Here, the electrical connection device 57 comprises fourteen electrical connection points 60.

[0298] The number of electrical connection points is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0299] Advantageously, the electrical connection points 60 are electrically connected to ports of the microcontroller 18 of the electronic control unit 17 by electrical tracks, not shown, printed on the first printed circuit board 26.

[0300] Here, the home automation installation 1 comprises the occultation device 3, the motorized drive device 10, as well as the terminal 68.

[0301] Advantageously, the connection module 61 comprises at least one second printed circuit board 82. The second printed circuit board 82 is housed inside the chassis 63. Furthermore, the first electrical connection pins 62 are integral with the second printed circuit board 82.

[0302] Advantageously, the first electrical connection pins 62 are electrically connected to the first cable 69 by electrical tracks, not shown, printed on the second printed circuit board 82.

[0303] Advantageously, the connection module 61 further comprises a handle 70. Furthermore, the movement mechanism 67 is configured to move, in other words displace, the first electrical connection pins 62 of the connection module 61 relative to the chassis 63 by actuation of the handle 70.

[0304] Advantageously, the handle 70 is actuated following the insertion of the connection module 61 inside the cavity 14 of the housing 43, so as to bring the first electrical connection pins 62 of the connection module 61 into contact with the electrical connection points 60 of the electrical connection device 57.

[0305] Advantageously, the handle 70 is accessible from outside the chassis 63 and from outside the housing 43, following the insertion of the connection module 61 inside the cavity 14 of the housing 43.

[0306] Advantageously, the movement mechanism 67 comprises at least a first ramp 71. The handle 70 comprises at least a second ramp 72. Furthermore, the first ramp 71 is pressed against the second ramp 72, during the movement of the first electrical connection pins 62 relative to the chassis 63 between the retracted position and the projected position and between the projected position and the retracted position.

[0307] Thus, the first and second ramps 71, 72 allow the first electrical connection pins 62 to be moved relative to the chassis 63 from the retracted position to the projected position, following the insertion of the connection module 61 inside the cavity 14 of the housing 43, and from the projected position to the retracted position, before the removal of the connection module 61 outside the cavity 14 of the housing 43.

[0308] Advantageously, an insertion or removal of the connection module 61 relative to the cavity 14 of the housing 43 is implemented along a direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0309] Here, the first and second ramps 71, 72 are inclined relative to the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0310] Advantageously, the first ramp 71 is preceded by a first flat zone 85 and followed by a second flat zone 86, following the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43. The first ramp 71 has a first end 71a and a second end 71b, the second end 71b being opposite the first end 71a. The first flat zone 85 is provided at the first end 71a of the first ramp 71 and the second flat zone 86 is provided at the second end 71b of the first ramp 71. The second ramp 72 is preceded by a third flat zone 87 and followed by a fourth flat zone 88, following the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43. The second ramp 72 has a first end 72a and a second end 72b, the second end 72b being opposite the first end 72a.The third flat area 87 is provided at the first end 72a of the second ramp 72 and the fourth flat area 88 is provided at the second end 72b of the second ramp 72. In the retracted position of the first electrical connection pins 62 relative to the chassis 63, the first flat area 85 bears against the third flat area 87 and the second flat area 86 bears against the fourth flat area 88. Furthermore, in the projected position of the first electrical connection pins 62 relative to the chassis 63, the second flat area 86 bears against the third flat area 87.

[0311] Here, the first, second, third and fourth planar zones 85, 86, 87, 88 are parallel to the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0312] Here, the first and second ramps 71, 72 are inclined relative to the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0313] Advantageously, the frame 63 further comprises at least one first stop 74. The handle 70 further comprises at least one second stop 76. In addition, the second stop 76 is pressed against the first stop 74, when the retracted position of the first electrical connection pins 62 is reached relative to the chassis 63.

[0314] Thus, the movement of the handle 70 inside the chassis 63 is limited by the support of the first and second stops 74, 76, during a retraction movement of the first electrical connection pins 62 relative to the chassis 63.

[0315] Advantageously, the connection module 61 further comprises elastic return elements 77.

[0316] Advantageously, when moving the first electrical connection pins 62 relative to the chassis 63 between the retracted position and the projected position, in particular by activating the handle 70 in the opposite direction, compared to that for moving the first electrical connection pins 62 relative to the chassis 63 between the projected position and the retracted position, each elastic return element 77 is configured to exert, in other words exerts, pressure on the chassis 63.

[0317] Thus, the elastic return elements 77 make it possible to guarantee the contacting of the first ramp 71 of the movement mechanism 67 with the second ramp 72 of the handle 70 and to guarantee the contacting of the first electrical connection pins 62 of the connection module 61 with the electrical connection points 60 of the electrical connection device 57, while limiting the value of a force exerted on the first electrical connection pins 62 and the electrical connection points 60.

[0318] Here, each elastic return element 77 is a spring, in particular in the form of a spiral.

[0319] Here, there are four elastic return elements 77, only three of which are shown in [Fig. 9] and only two of which are shown in [Fig. 10].

[0320] The number and type of each elastic return element are not limiting and may be different. They may be, for example, a spring blade and may be two or more in number.

[0321] Advantageously, the chassis 63 comprises guide studs 83. The second printed circuit board 82 comprises guide holes 84. Each of the guide studs 83 is housed, otherwise is configured to be housed, in one of the guide holes 84, in particular in an assembled configuration of the connection module 61. Furthermore, the printed circuit board 82 is guided in translation, otherwise is configured to be guided in translation, relative to the chassis 63, during the movement of the first electrical connection pins 62 relative to the chassis 63 between the retracted position and the projected position and between the projected position and the retracted position.

[0322] Advantageously, the number of guide studs 83 is equal to the number of guide holes 84.

[0323] Here and in a non-limiting manner, the guide studs 83 and the guide holes 84 are respectively four in number, of which only one of the guide studs 83 and only one of the guide holes 84 are shown in FIGS. 9 and 10.

[0324] Advantageously, each of the elastic return elements 77 is held, in other words is configured to be held, by one of the guide studs 83, in particular in the assembled configuration of the connection module 61. Furthermore, each of the elastic return elements 77 is guided, in other words is configured to be guided, relative to the guide studs 83, during the movement of the first electrical connection pins 62 relative to the chassis 63 between the retracted position and the projected position and between the projected position and the retracted position.

[0325] Advantageously, the number of guide studs 83 is equal to the number of elastic return elements 77.

[0326] Advantageously, a direction of movement T of the first electrical connection pins 62 of the connection module 61 relative to the chassis 63, during the movement of the first electrical connection pins 62 relative to the chassis 63 between the retracted position and the projected position and between the projected position and the retracted position, is orthogonal to the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0327] Here, the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43, during insertion or removal of the connection module 61 relative to the cavity 14 of the housing 43, is identical to that of the power supply unit 40 inside the cavity 14 of the housing 43, during insertion or removal of the power supply unit 40 relative to the cavity 14 of the housing 43.

[0328] Advantageously, the first printed circuit board 26 of the electronic control unit 17 extends inside the housing 43 and parallel to the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43.

[0329] Thus, the positioning of the second printed circuit board 82 inside the housing 43 makes it possible to maximize a surface area on which the first electrical connection pins 62 are installed.

[0330] Advantageously, the connection module 61 comprises third retaining elements 78. Furthermore, when the connection module 61 is housed inside the cavity 14 of the housing 43, replacing the power supply unit 40, each third retaining element 78 of the connection module 61 is configured to cooperate, in other words cooperates, with one of the second retaining elements 45 of the housing 43, so as to hold the connection module 61 in position inside the housing 43.

[0331] Thus, during a maintenance or repair intervention on the device motorized drive 10, the connection module 61 is housed inside the cavity 14 of the housing 43 in place of the power supply unit 40 and is held relative to the housing 43 by the same second retaining elements 45 of the housing 43 used to hold the power supply unit 40.

[0332] Advantageously, the third retaining elements 78 are identical to the first retaining elements 41, in particular in shape and number.

[0333] Thus, during a maintenance or repair operation on the motorized drive device 10, the connection module 61 is housed inside the cavity 14 of the housing 43 in place of the power supply unit 40 and is held relative to the housing 43 by means of retaining elements identical to those used to house and hold the power supply unit 40.

[0334] Here, the first retaining elements 41 and the third retaining elements 78 are elastic snap-fastening elements. Furthermore, the second retaining elements 45 of the housing 43 are the second openings.

[0335] Advantageously, the power supply unit 40 comprises a plurality of first electrical connection elements 54a, 54b. Each of the first electrical connection elements 54a, 54b comprises a first electrical contact zone 55. The electronic control unit 17 comprises a plurality of second electrical connection elements 56a, 56b, 56c. Each of the second electrical connection elements 56a, 56b, 56c comprises a further electrical contact area 79. Furthermore, when the power supply unit 40 is housed inside the cavity 14 of the housing 43, each of the first electrical contact areas 55 of the first electrical connection elements 54a, 54b is in electrical contact, in other words is configured to be in electrical contact, with one of the further electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c, in particular in the assembled configuration of the motorized drive device 10.

[0336] Alternatively, each of the other electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c is in electrical contact, in other words is configured to be in electrical contact, with one of the first electrical contact areas 55 of the first electrical connection elements 54a, 54b.

[0337] Thus, the mounting of the power supply unit 40 inside the cavity 14 of the housing 43 makes it easier to access the electrical energy source 12 to replace or recharge it, without having to dismantle the motorized drive device 10 relative to the rod 4. In particular, the electrical connection between the electrical energy source 12 and the electronic control unit 17 can be made regardless of the orientation of the power supply unit 40 when it is introduced into the cavity 14 of the housing 43.

[0338] Further, removing the power supply 40 from the housing 43 and placing the power supply 40 inside the housing 43 are defined to be performed using only one hand of an installer, so as to facilitate these operations and to guarantee the safety of the installer, in particular when the latter is mounted on a stepladder to reach the motorized drive device 10 mounted on the rod 4, since he can hold on to the stepladder with his second hand.

[0339] Furthermore, the electrical connection between the first electrical connection elements 54a, 54b and the second electrical connection elements 56a, 56b, 56c can be implemented in a compliant manner, regardless of the direction of insertion of the power supply unit 40 inside the cavity 14 of the housing 43.

[0340] Consequently, the power supply unit 40 is reversible with respect to its plane of symmetry PI, when mounting it inside the cavity 14 of the housing 43, while guaranteeing the conformity of the electrical connection of the electrical energy source 12 to the electronic control unit 17.

[0341] Advantageously, each of the second electrical connection elements 56a, 56b, 56c is electrically connected, in other words is configured to be electrically connected, to the first printed circuit board 26, in particular in an assembled configuration of the electronic control unit 17.

[0342] Here, each of the second electrical connection elements 56a, 56b, 56c is electrically connected to the first printed circuit board 26 by means of soldering.

[0343] Alternatively, not shown, each of the second electrical connection elements 56a, 56b, 56c is electrically connected to the first printed circuit board 26 by means of electrical connectors or an electrical wire.

[0344] Advantageously, each of the first electrical connection elements 54a, 54b further comprises a second electrical contact zone 64. Furthermore, each of the second electrical contact zones 64 of the first electrical connection elements 54a, 54b is in electrical contact, in other words is configured to be in electrical contact, with one of the electrical energy storage elements 27, in particular in the assembled configuration of the power supply unit 40.

[0345] Advantageously, the connection module 61 further comprises second electrical connection pins 80. Furthermore, when the connection module 61 is housed inside the cavity 14 of the housing 43, replacing the power supply unit 40, each of the second electrical connection pins 80 is in electrical contact, in other words is configured to be in electrical contact, with one of the other electrical contact zones 79 of the second electrical connection elements 56a, 56b, 56c.

[0346] Thus, the terminal 68 is configured to supply electrical energy to the electronic control unit 17 of the motorized drive device 10 by means of the connection module 61, following the electrical connection of the terminal 68 with the connection module 61 via the second cable 81 and the electrical connection of the connection module 61 with the electrical connection device 57 via the second electrical connection pins 80 and the second electrical connection elements 56a, 56b, 56c.

[0347] Advantageously, the second electrical connection pins 80 extend along the direction of movement Y of the connection module 61 inside the cavity 14 of the housing 43, during insertion or removal of the connection module 61 relative to the cavity 14 of the housing 43.

[0348] Advantageously, the second electrical connection pins 80 are integral with the second printed circuit board 82.

[0349] Advantageously, the second electrical connection pins 80 are electrically connected to the second cable 81 by electrical tracks, not shown, printed on the second printed circuit board 82.
