Definitions
- the invention relates to an electric actuator for driving a home automation screen, such as a shutter, blind, curtain, grille, projection screen or garage door.
- a home automation screen such as a shutter, blind, curtain, grille, projection screen or garage door.
- the actuator according to the invention is provided with a spring brake. This type of brake is particularly suitable for tubular motors.
- a coil spring brake in actuators for home automation screens is known, in particular in patent FR-B-2,610,668.
- a coil spring is mounted in a friction piece. At least one coil of the spring is radially constrained by a bore of the friction piece. Each end of the spring forms a tab extending radially inwardly of the spring. Each tab can be moved to cause the rotation of the spring relative to its axis.
- the input member, the output member and the spring are arranged specifically to obtain the following kinematics: an action of the input member located on one side of the first leg causes the rotation of the spring in a first direction .
- This movement releases the output member, i.e., it tends to decrease the diameter of the outer casing of the spring.
- the friction between the bore of the friction piece and the turns of the spring decreases, due to the decrease in the radial stress between the spring and the friction piece.
- an action of the output member on the opposite side of the first leg causes the rotation of the spring in the second direction, that is to say, the opposite direction.
- This movement blocks the output member, that is to say, it tends to increase the diameter of the outer casing of the spring.
- the friction between the bore of the friction piece and the turns of the spring therefore increases. It is the same for the radial stress between the spring and the friction piece.
- the input member may also act on the second leg of the spring to cause the rotation of the spring in the second direction while releasing the output member.
- the output member may also act on the second leg of the spring to cause the rotation of the spring in the first direction.
- the output member is blocked or, at least, is braked by the friction of the spring against the friction piece. Consequently, the rotation of the input member allows the rotation of the spring and the output member, while the rotation of the output member immobilizes the spring which blocks the primed movement of the output member.
- a similar brake is described in EP-B-2230415. This offers a spring brake with symmetrical operation, that is to say, with equivalent performance irrespective of the direction of rotation of the drive part.
- the axial displacement of the coil spring is stopped, in both directions, by two parts forming lateral stop abutments continuously integral in rotation about the axis of the spring.
- the spring is always pressed against a lateral stop piece having the same speed differential with the spring, that the drive part rotates in one direction or the other.
- the actuator then makes it possible to move the domotic screen without the spring inducing parasitic friction, since the spring and the lateral stop piece have the same rotation speed continuously, at the axial stop, when the brake is released.
- An object of the present invention is to improve the operation of a spring brake in all operating configurations, including in a driving load situation, while the speed of rotation of the load is greater than the exit speed of the load. the actuator, and thus that the brake is partially released.

- the friction element a friction is created between the brake input member and the brake output member, these two members being in contact with the folded tabs of a spring, thus creating a damping between these two organs.
- This high speed friction makes it possible to reduce or even eliminate the noise observed.
- the load speed at the output of the brake and the engine speed are smoothed by this friction device.
- the damping of the angular movement can be achieved by an elastic friction system.
