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

Generally speaking, the present invention relates to the field of curtains comprising a motorized drive device moving a screen relative to a rod following a sliding movement, between at least a first position and at least a second position.

We already know the document WO 2021/105320 A1 which describes a motorized drive device for a concealment device. The motorized drive device comprises a housing, a motor unit, a source of electrical energy, an electronic control unit and a support. The housing includes a cavity. The motor unit includes an electric motor and a drive wheel. The electric motor is configured to be supplied with electrical energy by means of the electrical energy source. The drive wheel is configured to be driven in rotation, around an axis of rotation, by means of the electric motor, and to be brought into contact with a surface of a rod of the concealment device, so as to move the motorized drive device along the rod following a direction of movement. This motorized drive device is generally satisfactory.

However, this motorized drive device has the disadvantage that the source of electrical energy is housed inside the housing and is placed against a wall of the housing and that the source of electrical energy is accessible, from from the outside of the housing, by dismantling one of the half-shells of the housing forming a hatch.

Thus, removing outside the enclosure and placing the electrical power source inside the enclosure requires the use of both hands of an installer.

Consequently, these operations are complex to implement by the installer and are sources of danger for the installer, in particular when he is mounted on a stepladder to reach the motorized drive device mounted on the rod, since 'he can't hold on to the stepladder with one of his hands.

Furthermore, the electrical connection of the electrical energy source to the electronic control unit requires a specific mounting direction of the electrical energy source inside the housing.

Therefore, the installation of the electrical energy source inside the enclosure requires specific knowledge of this operation by the installer.

The present invention aims to resolve 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 access to a source of electrical energy to replace or recharge it, without having to disassemble the motorized drive device from the rod.

The fixing elements of the casing 50 can be, for example, screw fixing elements.

The type of fixing elements of the first and second half-shells of the casing is not restrictive and may be different. These may be, for example, elastic snap fastening elements.

Advantageously, the or each elastic return element 44 is configured to cooperate, in other words cooperate, on the one hand, with the housing 43 and, on the other hand, with the casing 50, in particular in the assembled drive device configuration motorized 10. In addition, the drive wheel 13 is configured to be placed in support, in other words is placed in support, against the first surface 5 of the rod 4, by means of the or each elastic return element 44, in particularly in the mounted state of the motorized drive device 10 on the rod 4.

Thus, the motor unit 49 is mobile, in particular following the translation movement M, inside the housing 43, under the action of the elastic return elements 44, so as to support the drive wheel 13 against the first surface 5 of the rod 4, in particular in the assembled configuration of the concealment device 3. This corresponds to the translation movement M described previously.

Here, the elastic return elements 44 are configured to cooperate, on the one hand, with a first support wall 52 arranged inside the housing 43 of the motorized drive device 10 and, on the other hand, with the casing 50 of motorization block 49.

Advantageously, the first support wall 52 is parallel to the rod 4, in particular in the assembled configuration of the concealment device 3.

Here and in no way limiting, the first support wall 52 is produced by a part formed in each of the first and second half-shells 43a, 43b of the housing 43.

In the assembled configuration of the concealment device 3, the elastic return elements 44 make it possible to take into consideration an evolution of a mass of the screen 2 to be pulled or pushed by means of the motorized drive device 10, during 'a movement of the motorized drive device 10 along the rod 4 by the electrical activation of the electric motor 11, both for closing the screen 2 and for opening the screen 2, by adjusting a pressure exerted by the drive wheel 13 on the rod 4.

Advantageously, when the electric motor 11 is electrically activated, the casing 50 is configured to be inclined, in other words is inclined, inside the housing 43, relative to the median plane P of the housing 43.

In the assembled configuration of the concealment device 3, when the electric motor 11 is electrically activated, the drive wheel 13 is placed against the rod 4, via 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 X13, via the electric motor 11 and, possibly, the transmission device 28.

Thus, a compressive 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.

In this way, the motor unit 49 is in an inclined position inside the housing 43 and, more particularly, in relation to the rod 4.

Consequently, a bracing 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.

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

As a variant, not shown, when the electric motor 11 is electrically deactivated, the motor 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 concealment device 3, and following a movement of the motorized drive device 10 along the rod 4.

In the assembled configuration of the concealment device 3, when the electric motor 11 is electrically deactivated, the drive wheel 13 is placed against the rod 4, via the elastic return elements 44 bearing on the housing 43 and, more particularly, on the first support wall 52.

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.

In this way, the motor unit 49 can be in a vertical position inside the housing 43 and, more particularly, in relation to the rod 4 which, by hypothesis, is horizontal.

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, via the first and second holding devices 37, 39, in particular in the assembled configuration of the concealment device 3.

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 via the first and second holding devices 37, 39 cooperating with the rod 4, whether during electrical deactivation of the electric motor 11 or during electrical activation of the electric motor 11.

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 stopping the motorized drive device 10 relative to the rod 4 or during a movement of the motorized drive device 10 along the rod 4, implemented by the electrical activation of the electric motor 11.

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°.

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.

Due to the holding of the motorized drive device 10 relative to the rod 4 via the first and second holding 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.

We now describe, with reference to Figures 3 to 5 and 8 to 10, in more detail the support 40 of the motorized drive device 10, illustrated in Figures 1 to 7.

Mounting the support 40 inside the cavity 14 of the housing 43 makes it possible to facilitate access to the source of electrical energy 12 to replace or recharge it, without having to dismantle the motorized drive device 10 relative to the the rod 4. In particular, the electrical connection between the electrical energy source 12 and the electronic control unit 17 is carried out regardless of the orientation of the support 40 when it is introduced into the cavity 14 of the housing 43.

Furthermore, the removal of the support 40 outside the housing 43 and the installation of the support 40 inside the housing 43 are defined to be carried out using a single hand of an installer, so as to facilitate these operations and to guarantee the safety of the installer, in particular when he 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.

Furthermore, the electrical connection between the first electrical connection elements 54a, 54b and the second electrical connection elements 56a, 56b, 56c is implemented in a compliant manner, whatever the direction of insertion of the support 40 to the interior of cavity 14 of housing 43.

Consequently, the support 40 is reversible with respect to its plane of symmetry P1, when mounting it inside the cavity 14 of the housing 43, while guaranteeing the conformity of the electrical connection of the source of electrical energy 12 to the electronic control unit 17.

Advantageously, the support 40 comprises a first predetermined number of first electrical connection elements 54a, 54b. The electronic control unit 17 comprises a second predetermined number of second electrical connection elements 56a, 56b, 56c. Furthermore, the second predetermined number of second electrical connection elements 56a, 56b, 56c is greater than the first predetermined number of first electrical connection elements 54a, 54b by a value of one.

Thus, the electrical connection between the first electrical connection elements 54a, 54b and the second electrical connection elements 56a, 56b, 56c is implemented in a reversible manner, with respect to the first and second planes of symmetry P1, P2, given that the second electrical connection elements 56a, 56b, 56c comprise an additional electrical connection element compared to the first electrical connection elements 54a, 54b.

Advantageously, the support 40 comprises two first electrical connection elements 54a, 54b, in other words the first predetermined number of first electrical connection elements 54a, 54b is two. One of the first electrical connection elements 54a has a first polarity and the other of the first electrical connection elements 54b has a second polarity, the second polarity being opposite to the first polarity. In addition, the electronic control unit 17 comprises three second electrical connection elements 56a, 56b, 56c, in other words the second predetermined number of second electrical connection elements 56a, 56b, 56c is three. One of the second electrical connection elements 56a has a first polarity and two others of the second electrical connection elements 56b, 56c have a second polarity, the second polarity being opposite the first polarity.

Thus, the electrical connection between the first electrical connection elements 54a, 54b and the second electrical connection elements 56a, 56b, 56c is implemented in a reversible manner, with respect to the first and second planes of symmetry P1, P2, given that the second electrical connection elements 56a, 56b, 56c comprise an additional electrical connection element compared to the first electrical connection elements 54a, 54b.

Here, the first polarity of the first electrical connection element 54a and the first polarity of the second electrical connection element 56a are respectively the same. Furthermore, the second polarity of the first electrical connection element 54b and the second polarity of the second electrical connection elements 56b, 56c are respectively the same.

In addition, the first pad 57 maintains, in other words is configured to maintain, a first spacing distance D1 between the two first electrical connection elements 54a, 54b, in particular in the assembled configuration of the support 40, as illustrated in .

Thus, the first pad 57 makes it possible to guarantee an electrical insulation distance between the first electrical connection elements 54a, 54b, so as to avoid a malfunction of the electrical energy source 12 and the electronic control unit 17.

Advantageously, one of the second electrical connection elements 56a belongs to a first electrical tab 60. In addition, the other two of the second electrical connection elements 56b, 56c, of the same polarity, belong to a second electrical tab 61.

Thus, the electrical connection between the first electrical connection elements 54a, 54b and the second electrical connection elements 56a, 56b, 56c is implemented in a reversible manner, with respect to the first and second planes of symmetry P1, P2, given that the second electrical connection elements 56a, 56b, 56c are distributed between the first and second electrical tabs 60, 61, depending on the polarity of the second electrical connection elements 56a, 56b, 56c.

In addition, the cost of obtaining the motorized drive device 10 is minimized, since the second electrical connection elements 56b, 56c of the same polarity are grouped on the same electrical tab 61.

Here, the electronic control unit 17 includes the first and second electrical tabs 60, 61.

Advantageously, the housing 43 comprises at least two second studs 62.
