    The invention relates to the field of opening opening controls. More specifically, the invention proposes a motorized deployment opening control. The invention also relates to an opening with an opening control whose handle is flush with the outer surface of the opening. The invention also relates to a motor vehicle equipped with an external control opening sash.
    For aesthetic and aerodynamic reasons, a control handle for opening a motor vehicle door may be flush type. Such a handle has an outer surface at the outer surface of the door, so that it does not show a grip. It must be previously output, or deployed, to be entered by a user. This outward pivoting movement is driven by a motor driving the exit and storage of the handle.
    WO2012 / 021782 A2 discloses a vehicle door handle. In the retracted position, the handle is flush with the outer surface of the door. It is driven by a motor between a stowed position and an output position where a user can manipulate it to open the corresponding door. A drive mechanism connects the handle to the motor. The mechanism includes a connecting rod and a spring. It compresses when the motor causes the handle to deploy, but the handle remains stuck in the retracted position. This precaution offers the advantage of not damaging the engine despite a possible blockage of the handle by frost.
    However, the security of such a solution is limited. Indeed during the closing movement, the handle can jam the fingers of the user. The force of the motor can hurt a finger by pinching it. This generates a fear of the user, hence an anxiety effect detrimental to the perceived quality of the vehicle. The object of the invention is to solve at least one of the problems posed by the prior art. The invention also aims to improve the safety of a motorized handle for opening. Moreover, the invention aims at a simple, robust and compact solution. The invention relates to a set for opening opening control, in particular for a vehicle door, the assembly comprising: a support; a handle movable in a direction of deployment and movable in a direction of retraction relative to the support; an actuator with a housing and a first movable portion adapted to drive the handle in the deployment direction; notable in that the actuator further comprises a second movable portion which is adapted to deploy the handle via the first portion when the actuator is energized, and a one-way coupling system which is disposed in the housing and which is configured to couple the second portion to the first portion when the second portion is moving to drive the handle in the deployment direction.
    According to particular embodiments, the assembly may comprise one or more of the following characteristics, taken individually or according to all the possible technical combinations: the first mobile part is at least partially disposed in the housing. - The housing comprises a wall defining a sealed cavity in which is housed the one-way coupling system. - The assembly comprises return means configured to drive the handle in the retraction direction. - The assembly comprises damping means of the retraction movement of the handle. - The damping means are disposed within the housing of the actuator, and are optionally integrated in the one-way coupling system. - The one-way coupling system includes a freewheel mechanism. - The actuator is a rotary actuator or a linear actuator. - The first part is rigidly linked to the handle. - The housing comprises energy supply means passing through the wall of the housing. - The second part is uncoupled from the handle when said part moves in the direction of retraction. - The actuator is able to move the handle at least between a retracted position and an extended position relative to the support so as to be manipulated by a user. - The handle is movable to an open position unlocking; the deployed position being between the unlocking position and the retracted position. - The second part is at least partially or completely disposed in the housing. - The opening command is an external command. - The handle is a pivoting handle or a handle movable in translation. - The actuator is able to rotate the handle by at least 10 °, or 25 °, or 45 °. - The damping means are configured to oppose the return means. - The linear actuator comprises a rack driving the coupling system. - The damping means are one-way damping means. - The one-way coupling system is configured to uncouple the second part of the first part when the second part moves in a direction opposite to the direction for the deployment of the handle. The invention also relates to a vehicle opening comprising a set, remarkable in that the assembly is in accordance with the invention, optionally the opening and the handle comprise substantially parallel pivot axes. The invention also relates to a vehicle, in particular an automobile, comprising an opening with an opening opening control assembly, characterized in that the assembly is in accordance with the invention.
    In a particular embodiment, the handle comprises a first outer surface with a contour, and the opening comprises a second outer surface that is tangential to the first surface over the entire contour.
    In general, the particular modes of each object of the invention are also applicable to the other objects of the invention. As far as possible, each object of the invention is combinable with other objects. The invention improves the safety of an opening control handle of a motor vehicle door. The position of the handle is decoupled from the internal configuration of the actuator when the actuator initiates the retraction movement. The invention provides a compact assembly since the one-way coupling system is close to the source of motion. The coupling system and the damping means can be integrated in the same ring forming a connection between the moving parts. In parallel, reliability, mass and rigidity are optimized because the number of moving parts and the mobile interfaces are streamlined. In addition ; assembly, control, and supply costs are decreasing.
    The retraction torque of the handle becomes less than the opening torque due to the one-way coupling system. Also, the retraction movement of the handle may be slower, softer than the deployment one. This removes the anxiety effect despite rapid deployment. In addition, the decoupling makes it possible to pull more the handle to unlock the opening; without forcing on the actuator. Other features and advantages of the present invention will be better understood from the description given by way of example and with reference to the drawings among which:
    Figure 1 shows an opening with a handle according to the invention.
    Figure 2 shows a sectional view of the opening and the handle along an axis 2-2 plotted in Figure 1.
    Figure 3 illustrates an assembly for open sash control according to a first embodiment of the invention.
    Figure 4 is a top view of the pivoting handle according to the second embodiment of the invention.
    Figure 5 is a front view of an opening opening control assembly according to a second embodiment of the invention.
    Figure 6 is a top view of the pivoting handle according to the second embodiment of the invention.
    Figure 1 shows an opening 1 provided with a pivoting handle 4. The opening 1 may be an opening 1 of the vehicle (not shown), including a motor vehicle. However, other applications are possible. The opening 1 may correspond to a door for a passenger, or to a trunk flap. A window can translate in the opening 1, and possibly scan the handle 4. The handle 4 is that of an opening command of the opening, for example an external command. The opening control may comprise a locking and unlocking device (not shown) of the opening, which is controlled by the actuation of the handle 4. The control can engage with a keeper (not shown) secured to the body of the vehicle. According to an alternative of the invention, the handle is an interior control handle, that is to say arranged in the passenger compartment of the vehicle.
    The handle 4 can be integrated in the outer surface 6 of the opening 1. Its contour 5 matches the outer surface 6. A constant clearance separates the handle 4 of the outer surface 6 of the opening along the contour 5. Thus , the continuity of the outer surface 6 is generally preserved and the presence of the handle 4 is more discreet. This improves the perceived quality.
    FIG. 2 represents a section of the opening 1 and the handle 4 illustrated in FIG. 1. The section is taken along the axis 2-2 plotted in FIG. 1.
    The handle 4 is shown in solid line when in the retracted position in the opening 1, or home position; and in dashed lines in the deployed position, or operational position, where the handle 4 protrudes relative to the outer surface 6 of the opening 1. This deployed position may be a first deployed position. Optionally, the handle 4 can be moved to a second deployed position (shown in phantom) after manipulation by a user. This other movement may correspond to an unlocking movement of the associated opening 1. The first deployed position may be between the second deployed position and the retracted position.
    The outer surface 8 of the handle 4 is flush with the outer surface 6 of the opening 1. This type of assembly is also referred to as the Anglo-Saxon "flush". For this purpose, the opening 1 has a pocket 10 housing the handle 4 in retracted position. The pocket may be formed by a stirrup (not shown) on which the handle 4 is movably mounted. The stirrup can form a support for the handle 4 in order to link it to the opening 1. The handle 4 can be totally arranged in the pocket 10 in the retracted position. The periphery of the pocket 10 is tangent to the outer surface of the handle over its entire perimeter. The outer surfaces may have a surface continuity, so that the handle is integrated into the general outer surface of the leaf. In the deployed position, the handle 4 protrudes with respect to the opening 1.
    The handle 4 can be vertical pivot axis 12. This axis 12 can be parallel to that of the opening 1. The handle 4 can be connected to the opening 1 by means of a set of rods or levers, so that its instantaneous center of rotation describes a curve in the space. Since the handle 4 is integrated in the opening 1 so as to limit its grip from the outside when it is in the retracted position, an actuator 14 makes it possible to take it out of its pocket 10 so that it can then be grasped by a user. The actuator 14 is advantageously rigidly connected to the opening 1 and housed in its thickness.
    To allow the return of the handle 4 in the pocket, return means (not shown) are provided. They can be at the pivot axis 12. Alternatively, they can be at a distance. In this configuration, they can be hooked to the opening and the handle. The return means may comprise an elastic element, such as a spring.
    According to a variant of the invention, the handle is a handle movable in translation. For example the actuator pulls the handle by translating perpendicular to the outer surface of the opening. The unlocking movement of the opening can also be a translational movement.
    Figure 3 shows a set for opening control of the opening according to a first embodiment of the invention. The opening (not shown for the sake of clarity) and the associated elements may correspond to those described in relation to Figures 1 and 2. The assembly is shown from the front, for example from the inside of the vehicle. The actuator 14 may be electric. According to an alternative, it can use another energy, such as compressed air. The actuator 14 is movable in two directions, between at least two positions. In the deployment direction, it drives the handle 4 to its deployed position, where it occupies itself an extended position. The actuator 14 can be moved in a retraction direction that allows the retraction of the handle 4 in the opening. The assembly includes a one-way coupling system 16, also known as a one-way transmission system. The system 16 may include a freewheel mechanism. This type of mechanism is well known to those skilled in the art. The system 16 may include a mechanism with a pawl placed inside a ring gear. In one direction of rotation the pawl allows the rotation of the outer ring, in the other direction the pawl abuts against the internal teeth of the ring gear so as to stop the rotation. Or, the system 16 may comprise a mechanism with balls or rollers placed in a ramp hub. In one direction of rotation, the balls or the rollers exit the ramps so as to block an outer ring, in the other direction the ring is free to rotate.
    The handle 4 and the actuator 14 can be connected by means of a pivoting lever 18. This lever 18 is rigidly connected to the handle 4, it extends to the plumb of the actuator 14, possibly up to the plumb with the center of the actuator 14; or the axis of rotation 12 of the handle 4 and the actuator 14. The actuator 14 comprises a first movable portion 20 and a second movable portion 22. The first portion 20 is integral with the handle 4 and follows the movements, possibly via the optional lever 18. The first part 20 is an output part. When the actuator 14 is energized, the second portion 22 moves. The second part 22 is a conversion part that converts energy into motion. The second part 22 is the driving part. The supply allows a movement of the second part 22 in the direction of deployment, and possibly in the direction of retraction. The moving parts (20; 22) may comprise angular stops acting in a direction of rotation.
    The first portion 20 and the second portion 22 are disengaged. However, they are each engaged with the coupling system 16. The coupling system 16 separates the moving parts (20; 22). It allows to communicate a movement of the second part 22 to the first part 20 when the second part 22 moves in the direction of deployment to deploy the handle 4. The coupling system 16 being one-way, when the second part 22 moves in the direction of retraction, it is released from the first part 20. So the movement of the handle is free from that of the second part 22. When the supply controls the return of the second part 22 in a retracted position , the handle 4 can return to its retracted position more slowly, more gradually. In addition, the coupling system 16 is able to hold the handle 4 in a given position, in particular its deployed position, despite the action of the return means. The actuator advantageously comprises a housing 24. This housing 24 can be fixed to the structure of the opening it equips. It can be attached to the stirrup of the handle 4. The housing 24 may comprise a wall 26 defining a space in which are arranged the coupling system 16 and the second part 22. The first part 20 is partially housed in this space . Thanks to the wall 26, and possibly through joints, the space can be a sealed cavity. Bearings, such as bearings, can articulate the moving parts (20; 22) with respect to the wall 26. By integrating the coupling system 16 in the housing 24, a general saving of space is ensured. In a complementary manner, the coupling system 16 is protected.
    Insofar as the handle 4 is subjected to return means (not shown) when the actuator 14 retracts, damping means 28 are provided to slow down the return of the handle 4. These damping means 28 are calibrated depending on the mechanical action of the return means, and the desired return time to reduce the anxiogenic effect associated with the handle 4. The damping means 28 may comprise a braking fluid, for example a viscous fluid generating a resistance during a relative rotation between the first portion 20 and the second portion 22. The fluid may be in contact with the pawl or rollers of the coupling system 16. Alternatively or in addition, the damping means 28 may comprise surfaces friction cooperating so as to oppose the relative rotation between the handle 4 and the actuator 14. It may be sets of rotor disks and stator, arranged in the manner of a clutch. At least one of the friction surfaces may be a surface of the coupling system. Thus, it is possible to integrate the damping means 28 in the coupling system 16.
    The damping means 28 can be engaged with the first part 20 and with the second part 22. Energy supplies 30, for example these cables can pass through the wall 26. According to an alternative of the invention, the means of damping can be remote from the coupling system. They can be in contact with the first lever and / or the handle.
    FIG. 4 shows a view from above of the opening opening control assembly which is shown in FIG. 3. The lever 18 makes it possible to disengage the handle 4 of the actuator 14, and in particular of the housing 24. The handle 4 is shown in the retracted position with a continuous line. In this position it is flush with the opening 1. The extended position of the handle 4 is drawn with a dotted line. The angle swept by the handle 4 through the actuator 14 is greater than or equal to 10 °.
    Figure 5 shows the opening control assembly according to a second embodiment of the invention. The opening (not shown for the sake of clarity) and the associated elements may correspond to those of FIGS. 1 and 2. This FIG. 5 repeats the numbering of the preceding figures for identical or similar elements, the numbering being incremented by 100, however. Specific numbers are used for the specific elements of this embodiment. The actuator 114 may be linear. The first moving part 120 and the second moving part 122 can move in translation. They can be telescopic. They can each slide relative to the housing 124. In particular, the first portion 120 can enter and exit the housing 124. The one-way coupling system 116 connects it selectively. When the second part 122 pushes the first part 120, the latter follows the movement. On the other hand, the first part 120 can be pulled more without the second part 122 following, and the second part 122 can return to the retracted position without the first part 120.
    The first portion 120 may comprise an end with a rack 132 cooperating with a rod 134 integral with the handle 104. The end of the rod 134 may comprise a pinion 136 meshing with the rack 132 so that a translation of the first part 120 allows a rotation of the handle 104. Therefore, a sliding of the second portion 122 can cause a deployment movement of the handle 104.
    According to an alternative of the invention, the first movable portion 120 may comprise a pusher rotating a cam formed in place of the pinion.
    The movable portions (120; 122) may include axial stops acting in a translation direction. This allows a drive in the direction of deployment, and allows freedom of movement when the stops are remote.
    FIG. 6 shows in top view the assembly according to the second embodiment of the invention as shown in FIG.
    The pinion 136 as the rack 132 are visible. They form the interface between the first portion 120 and the handle 104. The simultaneous translation of the second portion 122 and the first portion 120 allows the rotation of the handle 104, for example by an angle greater than or equal to 10 °. This makes it possible to get it out of its opening enough for a user to manipulate it. Depending on the stroke of the moving parts (120; 122), it is possible to rotate the handle 104 by 90 °.
    Both embodiments can be combined with each other. Features presented in one mode may apply to the other mode.
