Description

Electromechanical actuator and occultation device comprising such an electromechanical actuator

The present invention relates to an electromechanical actuator for a blackout device, in other words an electromechanical actuator of a blackout device.

The present invention also relates to a concealment device comprising a screen driven in movement by such an electromechanical actuator.

In general, the present invention relates to the field of occultation devices comprising a motorized drive device setting a screen in motion, between at least a first position and at least a second position.

A motorized drive device comprises an electromechanical actuator of a movable closing, concealing or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter called a screen.

Document EP 4 008 876 A1 is already known, which describes an electromechanical actuator of a concealment device comprising a housing, a torque support, an electric motor and an electronic control unit. The torque support comprises a housing. The electric motor is mounted inside the housing. The torque support comprises a first part, a second part and a display device. The first part is assembled with the housing. The second part is configured to be assembled with a device for holding the concealment device. The display device comprises one or more lighting sources. The or each lighting source is housed inside the housing of the torque support. In addition, the or each lighting source is controlled by the electronic control unit to emit light. This electromechanical actuator is generally satisfactory.

However, this electromechanical actuator has the disadvantage that the display device further comprises a transparent or translucent cover and/or a light guide.

Thus, the display device requires, in addition to the lighting source(s), one or more elements to diffuse and/or guide the light emitted by the or each lighting source.

Therefore, the electromechanical actuator is expensive due to the number of parts making up the display device and the complexity of assembling the display device at the torque support.

Furthermore, the transparent or translucent cover and/or the light guide constituting part of the display device only allow the light emitted by the lighting source(s) to be diffused at a specific point at the torque support.

Therefore, the light emitted by the light source(s) may be masked by the holding device or any other element belonging to the occultation device.

Furthermore, the first and second parts of the torque support form a single piece.

Therefore, the integration of the display device at the torque support level is complex and difficult to industrialize.

The present invention aims to solve the aforementioned drawbacks and to propose an electromechanical actuator of a concealment device, as well as a concealment device comprising such an electromechanical actuator, making it possible to simplify an assembly of a display device of the electromechanical actuator at a torque support, while minimizing the cost of obtaining the electromechanical actuator.

In this regard, the present invention aims, according to a first aspect, at an electromechanical actuator for a concealment device,

the electromechanical actuator comprising at least:

- a crankcase,

- a torque support,

- an electric motor, the electric motor being mounted inside the housing, and

- an electronic control unit,

the torque support comprising at least:

- a first part, the first part being assembled with the casing,

- a second part, the second part being configured to be assembled with a device for holding the occulting device,

- accommodation, and

- a display device,

the display device comprising at least:

- a light source, the light source being housed inside the torque support housing, the light source being controlled by the electronic control unit to emit light.

According to the invention, the second part of the torque support is assembled on the first part of the torque support. Furthermore, the second part of the torque support is a light guide diffusing the light emitted by the lighting source, from the housing of the torque support towards the outside of the torque support.

Thus, the display device is arranged at the torque support in a simple manner and allows light to be diffused from the housing of the torque support to the outside of the torque support through the second part of the torque support, while minimizing the cost of obtaining the electromechanical actuator.

In this way, the display device does not require any additional parts, since the second part of the torque support forms a light guide and since the second part of the torque support is assembled on the first part of the torque support.

In other words, the torque support consists of at least two separate parts, each forming respectively the first and second parts of the torque support.

Furthermore, the display device makes it possible to visually indicate to a user or an installer an operating mode and/or an operating state of the electromechanical actuator, at any time during use of the electromechanical actuator, in other words during commissioning or during operation of the electromechanical actuator, through the torque support forming a light guide.

Furthermore, the use of the torque support as a light guide makes it possible to avoid the need for specific positioning of a lighting source or a light diffusion element in relation to the torque support.

Therefore, the light emitted by the lighting source is diffused through the second part of the torque support, all around the electromechanical actuator and in all directions, so that it is visible outside the torque support, even if part of this light may be masked by the holding device or any other element belonging to the occulting device.

According to an advantageous characteristic of the invention, the second part of the torque support is transparent or translucent.

According to another advantageous characteristic of the invention, the lighting source is configured to emit light according to a first color, when the electromechanical actuator is in a first operating mode. Furthermore, the lighting source is configured to be turned off, when the electromechanical actuator is in a second operating mode.

According to another advantageous characteristic of the invention, the first operating mode of the electromechanical actuator is a configuration mode. Furthermore, the second operating mode of the electromechanical actuator is a control mode in operation.

According to another advantageous characteristic of the invention, the lighting source is configured to emit light according to a predetermined flashing frequency, when the electromechanical actuator is in the first operating mode and a type of control of the electromechanical actuator is expected.

According to another advantageous characteristic of the invention, the lighting source is configured to emit light according to the predetermined flashing frequency and according to a second color, when the electromechanical actuator is in the first operating mode and a first type of control of the electromechanical actuator is expected. Furthermore, the lighting source is configured to emit light according to the predetermined flashing frequency and according to a third color, when the electromechanical actuator is in the first operating mode and a second type of control of the electromechanical actuator is expected. Finally, the third color is different from the second color.

According to another advantageous characteristic of the invention, the lighting source is configured to emit light in a fourth color, when the electromechanical actuator is in a state of malfunction, the fourth color being different from the first color.

According to another advantageous characteristic of the invention, the display device comprises a plurality of lighting sources, each lighting source being configured to emit a light of a different color.

Alternatively, the or each light source is configured to emit light in different colors.

The present invention aims, according to a second aspect, at a concealment device, the concealment device comprising at least:
