Definitions
- the present invention concerns a vehicle door handle assembly, in particular with a flushing door handle lever.
- vehicle door handle assembly comprises a motorized actuator which, when actuated, moves the handle lever between a flush position and a ready position.
- the handle lever In the flush position, the handle lever is flush i.e. co-planar with the exterior surface of the door body.
- the handle lever In the ready position, the handle lever is protruding from said exterior surface, to be graspable by a user.
- the door handle lever interacts (via a Bowden cable, a rotating pin and/or a gear mechanism) with a latch mechanism to unlatch the door.
- a handle lever spring brings the handle lever back in its ready position when the user releases the handle lever. It is also possible for the motorized actuator to move the handle lever from the ready position back to the flush position after door opening or door closing however, this is however mostly performed by a return spring mechanism.
- the use of a motorized actuator is nevertheless not compulsory for flush door handles, those can be non-motorized concepts.
- the patent application US 2016290018 is known, it deals with a system including a component that can be mounted movably in or on an automobile and an actuating apparatus for the component, the actuating apparatus having a push-push mechanism that interacts with the component. It is possible for the component to be moved out of a closed position by manual exertion of a pressing force counter to the pre-stress of a spring into an unlocked position to unlock the push-push mechanism, out of which unlocked position the component is moved into a partially open position driven by the pre-stress of the spring. Eventually, out of the partially open position the component can be displaced into an open position by manual exertion of a pulling force.
- the push-push mechanism in this disclosure has to overcome the actuation mechanism with the gearing system integrated leading to stability issues and premature wearing.
- the motorized actuator sets the handle lever in motion via a reduction mechanism, for example a worm drive and gear mechanism, which reduces the rotational speed of the motor actuation while increasing torque value to push the handle lever out into its ready position.
- a reduction mechanism for example a worm drive and gear mechanism
- Such door handle assemblies i.e. motorized one, also comprise a back-up mechanism, as in document US 2016369537 disclosing a handle including an activation member for activating a latch of a vehicle door to unlatch the door and a grip member that cooperates with the activation member to unlatch the door.
- the grip member presents a gripping part and is movable between a flushing position in which the gripping part extends flush to an external panel of the door, an active position in which the gripping part projects with respect to the external panel, becoming graspable, and an opening position in which the grip member drives the activation member to unlatch the door.
- the handle presents a driving mechanism and an actuator lever cooperating with the grip member to drive the latter between the flushing and the active position. When the grip member is pulled in an opening direction, the grip member drives the activation member that unlatches the door.
- this mechanism comprises a push-push mechanism, in which the user pushes the handle lever inwards from its flushing position until reaching a clicking position in which a preloaded spring is released. Said preloaded spring, when released, pushes the handle lever from the inward clicking position to the outward protruding ready position.
- the invention deals with an actuator integrated coupling device for a vehicle door handle, the door handle having a handle lever movable between:
- the actuator integrated coupling device is characterized in that the motorized actuator comprises an electric motor coupled with a worm drive, said worm driving being coupled with a reduction mechanism to set in rotation the shaft of the cam when the electric motor rotates.

- the actuator integrated coupling device according to the invention is characterized in that the two arms of the connecting rod are parallel.
- the actuator integrated coupling device is characterized in that the first lever comprises at least one arm, said arm having a slotted hole for the coupling with the connecting rod.
- the slotted hole gives a degree of freedom needed to pull the handle lever further from the ready position to unlatch it. Without said degree of freedom, the fully extended push-push unit would not allow further pulling for door unlatching.
- the actuator integrated coupling device is characterized in that the push-push unit is also coupled, at its end opposite to the one coupled to the connecting rod, to a resetting lever system displaceable by the cam so as to push the push-push unit back to its pre-stressed state and pull the first lever, to bring the door handle lever back to its initial flush position.

- the invention is about a coupling device for a flush door handle to be operated in emergency or other cases.
- the current invention separates the actuator and the push-push system in order to avoid moving the internal parts of the actuator in case of an electrical failure. Furthermore, the system allows the actuator to deactivate the push-push system to retract the door handle.
- Figure 1 shows a perspective view of a vehicle Ve, its door panel 100 having a built-in door handle 1.
- the door panel 100 forms an exterior surface of the vehicle, the door handle 1 is essentially represented by its handle lever 3 (the part meant to be grasped and set in motion by a user).
- the handle lever 3 is in a flushing position.

- the handle lever 3 also appears integrated in the door panel 100 in a pleasant and discrete way.
- the user can push the lever 3 inwards with respect to the door panel 100, by applying inwards directed pressure Pon the handle lever 3.

More specifically, the small spring 93a biases a rotatable ring 95 towards the push-push driver 91. The main spring 93b biases the push-push driver 91 towards its outer aperture via its radial flange 91b to push the handle lever 3-via first lever 6-from retracted to ready position.

- said mechanism of handle movement comprises a second lever 7 connected by two articulated connection 801,802 to linking rods 81,82 and mounted in an articulated manner on parallel rotation axis A6, A7 carried by the handle.
- This double linking rod system brings stability.
- the two linking rods 81 and 82 are symmetrical with respect to a median plane extending in a longitudinal direction of the handle; said plane is perpendicular to the first and second lever rotation axis A6 and A7.
- Each of the linking rods 81 and 82 has oblong holes 811 close to the articulated connection 801 and 802 extending parallel to the linking rods.

- Figure 14 first figure on the left, is the initial position of the connecting rod 2 (see fig. 8 for larger view). Then in figure 14 , second figure on the middle, the handle lever is being pushed as depicted on the picture on the right. In this case, we see a longitudinal displacement towards the right hand side pre-stressing the push-push unit 9 and more precisely, the springs 93a and 93b.
- the sequence is as follows: The user pushes the handle lever 3. Since it is linked to the first lever 6, it creates a rotation about the first axis A6 of the first lever 6. Such rotation displaces the connecting rod 2 since they are linked by the slotted hole 811.
- the arm 23 transmits to the connecting rod 2 the displacement, thus pushing the push-push unit 9 to pre-stress it as can be seen in the second figure in the middle of fig. 14 .
- the push-push unit is pre-stressed, if a user pushes it from flush position, the rotatable ring 95 rotates and then slides through the grooves 94a as explained above to push the handle 3 from flush to ready position.
- FIG 15 where the right hand drawing shows a door handle lever 3 in ready position.
- Such situation occurs naturally when the user locks the car and works away.
- it may also occur, for instance, when the battery was empty during car park leaving the handle lever 3 in ready position and then reloads once the problem has been solved and the engine runs because the user is driving the car.
- the handle lever must be flush after a certain car speed.
- the cam 4 keeps rotating clockwise and its chamfer 41 follows the oblique surface 101d of the cam lever 101. This deflects the cam lever 101 downwards allowing the cam 4 to go back to initial position. After deflection of the cam lever 101, a spring 102 biases back said cam lever 101 to its initial position in the same plane as the rotation plane of the cam 4.
- the coupling device according to the invention can be used for flush door handles extracting either rotationally or translatively as explained.
- the coupling device can be adapted to fit any door requiring a flush type handle mechanism.
- a notable advantage of the push-push unit 9 according to the invention is that on one hand it can be activated and deactivated mechanically from one side and on the other hand it can be activated and deactivated electronically-via the motorized actuator 8- from the other side. Therefore, if the push-push unit is activated manually to put the handle lever 3 in ready position, it can afterwards be reinitialized in a motorized way, i.e. set back in flush position electronically.

Abstract
Description
- The present invention concerns a vehicle door handle assembly, in particular with a flushing door handle lever. Such vehicle door handle assembly comprises a motorized actuator which, when actuated, moves the handle lever between a flush position and a ready position. In the flush position, the handle lever is flush i.e. co-planar with the exterior surface of the door body. In the ready position, the handle lever is protruding from said exterior surface, to be graspable by a user.
- Once the user grasps the handle lever in its ready position, he can pull the lever in a further protruding position and unlatch the door. Indeed, the door handle lever interacts (via a Bowden cable, a rotating pin and/or a gear mechanism) with a latch mechanism to unlatch the door.
- Generally, in door handles, a handle lever spring brings the handle lever back in its ready position when the user releases the handle lever. It is also possible for the motorized actuator to move the handle lever from the ready position back to the flush position after door opening or door closing however, this is however mostly performed by a return spring mechanism. The use of a motorized actuator is nevertheless not compulsory for flush door handles, those can be non-motorized concepts.
- The patent application
US 2016290018 is known, it deals with a system including a component that can be mounted movably in or on an automobile and an actuating apparatus for the component, the actuating apparatus having a push-push mechanism that interacts with the component. It is possible for the component to be moved out of a closed position by manual exertion of a pressing force counter to the pre-stress of a spring into an unlocked position to unlock the push-push mechanism, out of which unlocked position the component is moved into a partially open position driven by the pre-stress of the spring. Eventually, out of the partially open position the component can be displaced into an open position by manual exertion of a pulling force. - It is however much more comfortable to have a motorized mechanism that can make the door handle lever available for pulling after any recognition system and/or action of the car owner. Furthermore, the push-push mechanism in this disclosure has to overcome the actuation mechanism with the gearing system integrated leading to stability issues and premature wearing.
- Nowadays, generally speaking, the motorized actuator sets the handle lever in motion via a reduction mechanism, for example a worm drive and gear mechanism, which reduces the rotational speed of the motor actuation while increasing torque value to push the handle lever out into its ready position.
- Such door handle assemblies, i.e. motorized one, also comprise a back-up mechanism, as in document
US 2016369537 disclosing a handle including an activation member for activating a latch of a vehicle door to unlatch the door and a grip member that cooperates with the activation member to unlatch the door. The grip member presents a gripping part and is movable between a flushing position in which the gripping part extends flush to an external panel of the door, an active position in which the gripping part projects with respect to the external panel, becoming graspable, and an opening position in which the grip member drives the activation member to unlatch the door. The handle presents a driving mechanism and an actuator lever cooperating with the grip member to drive the latter between the flushing and the active position. When the grip member is pulled in an opening direction, the grip member drives the activation member that unlatches the door. - To enable the opening of the door in case of, for example, motorized actuator or car battery failure, i.e. when the motorized actuator cannot be actuated, this mechanism comprises a push-push mechanism, in which the user pushes the handle lever inwards from its flushing position until reaching a clicking position in which a preloaded spring is released. Said preloaded spring, when released, pushes the handle lever from the inward clicking position to the outward protruding ready position. Once the user accesses the vehicle in back-up mode, the battery will generally be recharged, and/or the motor failure will be lifted and normal, electric, actuation can be resumed.
- In application
US 2016369537 , just like inUS 2016290018 , the flush door handle pops out in a rotational movement which is a common lever extraction for flush door systems. In these prior art mechanisms, the push-push mechanism is integrated inside the actuator mechanism; therefore, the gear mechanism inside the actuator is driven when the back-up manual mode is used. This is detrimental to the door handle stability and means that the actuation mechanism is set in motion even when back-up manual mode is used. This increases the mechanism wearing. - Eventually, the gearing system of the actuator has to be reversible since the back-up manual mode drives back the completely motorized actuation mechanism. This reversibility means that the gearing system, at the ready position, should be able to return to flush position biased by return springs, henceforth a brake might be needed to guarantee a stable ready position. All these constraints lead to a complex flush door handle.
- In order to overcome the aforementioned drawbacks, the invention deals with an actuator integrated coupling device for a vehicle door handle, the door handle having a handle lever movable between:
- a flush position in which it is flush with an exterior door panel surface,
- a ready position in which it is protruding and graspable by a user,
- and an inward clicking position in which the handle lever is in a retracted position inside the vehicle door, said coupling device comprising:
- a cam rotatable about an axis,
- a motorized actuator for rotating said cam,
- a transmission mechanism comprising a first lever for coupling with the cam to move the handle lever between said flush, ready and retracted positions,a push-push unit, coupled to the first lever by a connecting rod so that when the handle lever is pushed to the inward clicking position, the push-push unit pushes back the handle lever in the ready position.
Characterized in that the push-push unit and the motorized actuator are decoupled to allow the push-push unit to move the door handle lever between said flush, ready and retracted positions while the motorized actuator is not subjected to any mechanical strain.
- In a preferred embodiment, the actuator integrated coupling device according to the invention is characterized in that the motorized actuator comprises an electric motor coupled with a worm drive, said worm driving being coupled with a reduction mechanism to set in rotation the shaft of the cam when the electric motor rotates. This improves the motor efficiency.
- In a preferred embodiment, the actuator integrated coupling device according to the invention is such that the first lever comprises elastic return means, for example a torsion spring or a double torsion spring, to push said first lever back to its flush position once the handle lever has reached ready position.
- In another preferred embodiment, the actuator integrated coupling device according to the invention is characterized in that the transmission mechanism further comprises:
- a first lever axis, the first lever being rotatable about said first lever axis parallel to the cam axis,
- a second lever rotatable about a second lever axis,
- the first and second levers axis being parallel and longitudinally distant from one another,
- at least one linking rod having its ends connected to the first lever and the second lever in articulated connections,
- at least one of said connections comprising a first slotted hole parallel to said linking rod ,
- The first lever, the second lever, the linking rod and the handle lever forming a kinematics assembly whose deformation is able to displace the handle lever in translation. The translation extraction of the door handle lever is an alternative to a rotation extraction mode.
- Alternatively, the actuator integrated coupling device according to the invention can be such that the first lever is rotatable about a first lever axis parallel to the cam axis, and is directly coupled to the handle lever so that the cam, the first lever and the handle lever form a kinematics assembly whose deformation is able to displace the handle lever in rotation. The rotation extraction of the door handle lever is an alternative to the translation extraction.
- Preferably, the actuator integrated coupling device according to the invention is characterized in that the connecting rod is made of a central rod having, at its two ends, two arms forming each a right angle with the central rod. Such coupling allows better movement transmission between the push-push unit and the first lever.
- In a further preferred embodiment and further improve movement transmission, the actuator integrated coupling device according to the invention is characterized in that the two arms of the connecting rod are parallel.
- In another preferred embodiment, the actuator integrated coupling device according to the invention is characterized in that the first lever comprises at least one arm, said arm having a slotted hole for the coupling with the connecting rod. The slotted hole, gives a degree of freedom needed to pull the handle lever further from the ready position to unlatch it. Without said degree of freedom, the fully extended push-push unit would not allow further pulling for door unlatching.
- Ideally, the actuator integrated coupling device according to the invention is characterized in that the push-push unit is also coupled, at its end opposite to the one coupled to the connecting rod, to a resetting lever system displaceable by the cam so as to push the push-push unit back to its pre-stressed state and pull the first lever, to bring the door handle lever back to its initial flush position. The main advantage here is that on one hand the push-push unit can be activated and/or deactivated both mechanically and electronically via a motorized actuator.
- So as to optimize space distribution of the coupling device and reduce its volume, the resetting lever system preferably comprises:
- a rotatable connecting lever having a central portion and ,at its ends, two radial arms rotatable about the axis of the connecting lever, the first radial arm being coupled to the push-push unit,

Figure 1 shows a perspective view of a vehicle Ve, itsdoor panel 100 having a built-in door handle 1. Thedoor panel 100 forms an exterior surface of the vehicle, the door handle 1 is essentially represented by its handle lever 3 (the part meant to be grasped and set in motion by a user). - The terms like "inwards", "outwards" and equivalents refer to the vehicle interior and exterior. The terms longitudinal, transversal and vertical refer to the directions as drawn in
figure 1 . - In
figure 1 , thehandle lever 3 is in a flushing position. In said flushing position, the outer surface of thehandle lever 3 is flush with thedoor panel 100. Said flush position is obtained when the vehicle is rolling or when it is parked. In flush position, thehandle lever 3 is less likely, when parked, to interact with by passers, accidentally or not, and air drag is reduced when driving, improving aerodynamics. In the flush position, thehandle lever 3 also appears integrated in thedoor panel 100 in a pleasant and discrete way. - In the event of a mechanical or electrical failure of the mechanism that drives the
lever 3 from the flush position to the ready position, the user can push thelever 3 inwards with respect to thedoor panel 100, by applying inwards directed pressure Pon thehandle lever 3. Thehandle lever 3 is then in a position herein called clicking position, where a mechanical interaction releases a spring of a push-push unit that drives thelever 3 in ready position without actuation of a motor. - A push-push unit per-se is known in the art, for instance, US patent application
US 2011/0174102 explains one of them with the principle detailed and said application is incorporated here by reference. - The
figure 2 shows a coupling device according to the invention. Thefirst lever 6 comprises twoarms first lever 6, said median plane being perpendicular to the cam 4 rotation axis A6. A double torsion spring lies on the first lever rotation axis A6 to bring thefirst lever 6 back to flush position from ready position. - One of the two
arms 62 has a slottedhole 62a coupled to the connecting rod 2 (fig. 4 and 5 ). Infigure 2 , such connection is made through anarm 21 of the connectingrod 2. The connectingrod 2 has twoparallel arms central rod 22 perpendicular with botharms - The push-push unit 9 depicted in
figure 2 is able to displace the arm 23-hence the connecting rod 2- longitudinally along an axis (90). This push-push unit 9 can be pre-stressed by the connectingrod 2 or by a resettinglever system 10. - The resetting system of
figure 2 comprises: - a rotatable connecting lever 106 (
figure 5 ) having acentral portion 106a and, at its ends, tworadial arms axis 110 . The firstradial arm 106c is coupled to the push-push unit 9; - and a cam lever 101 (
fig. 3-5 ) with acentral portion 101a and twoends first end 101c being coupled in a rotatable manner about an axis 111 (fig. 4 ) to the secondradial arms 106b of the connectinglever 106, and thesecond end 101b extending perpendicularly to thecentral portion 101a and being displaceable by a cam 4. - It is important to note that
cam lever 101 has two degrees of freedom, it is able to rotate aboutaxis 111 and to translate longitudinally. - The rotation axis 110 (
fig. 4 ) of the connectinglever 106 and therotation axis 111 of thecam lever 101 are parallel and both perpendicular to thecam rotation axis 42. - The cam 4 (also in
fig. 3 and 4 ) comprises tworadial arms axis 42. Theradial arms cam rotation axis 42. It should be noted that a cam with a single arm (4a, 4b) is another preferred alternative that would also provide the same effect. The cam 4 can both rotate thefirst lever 6 and translate thecentral portion 101a of thecam lever 101. - The cam 4 also comprises a chamfer 41 (
fig.3 ) andlateral surface 40. Thechamfer 41 makes the link between thelateral surface 40 of the cam 4 and the lower surface-parallel to the rotation plane of the cam 4. Said rotation plane being perpendicular to therotation axis 42 of the cam 4. - The
actuator 8 comprises a motor and gearing system (both not represented) to drive in rotation the cam 4. - In
figure 3 , one can see the cam leversecond end 101b ending by anoblique surface 101d complementary to thechamfer 41. - Referring now to
figures 4 to 7 related to the push-push unit 9 and the resettinglever system 10, we describe their components below. - In
figure 4 , we can see the guiding rod 94 (see alsofigure 5 ) as well as the push-push driver 91 and thecarrier 92 of the push-push unit 9. - The push-push unit 9 comprises a cylinder shaped
sleeve 96 inside which a push-push driver 91 is housed in an axially displaceable manner along an axis 90 (fig.2 ) while being projectable through a sleeve aperture out of thesleeve 96. - The
sleeve 96 cannot rotate since anouter protrusion 96a is housed in a corresponding groove of the push-push unit housing H (fig. 5 ) to guarantee axial displacement only. - In addition, as better seen from
figure 6 , the push-push unit 9 comprises twosprings figure 6 for clarity), pre-stressing the push-push driver 91 to project from thesleeve 96. More specifically, thesmall spring 93a biases arotatable ring 95 towards the push-push driver 91. Themain spring 93b biases the push-push driver 91 towards its outer aperture via itsradial flange 91b to push the handle lever 3-via first lever 6-from retracted to ready position. Both small andmain springs radial flange 94c of the guiding rod 94 (fig. 5 and7 ). - The push-push unit 9 further comprises a
rotatable ring 95 enclosing the guidingrod 94 and supported in thesleeve 96 in an axially and rotationally displaceable manner. However, saidrotatable ring 95 has at least one protrusion towards the inner circumference of saidring 95 being able to engage the guiding rodradial grooves 94a (fig. 5 and7 ) so that thering 95 retains its angular position when the guidingrod 94 is axially displaced. - In
figure 6 , between the guiding rodradial flange 94c and the connecting lever firstradial arm 106c, there is an adjustment screw that allows regulating the push-push system pre-stress manually. - The
figure 7 shows again the guidingrod 94 of a preferred embodiment of the invention, co-axial with the axis 90 (fig.2 ), withradial grooves 94a running parallel to theaxis 90 and theradial flange 94c able to act as a rest for thespring rod 94 has lockingrecesses 94b placed radially between the entries of thegrooves 94a. - These locking recesses can receive at least one protrusion at the inner circumference of the
ring 95 once the push-push driver 91 is released by thehandle lever 3 after a first inward stroke by a user. Then thesprings ring 95 in thelocking recess 94b leading to a locked position. An outerradial protrusion 94d is associated with the guidingrod 94 flange to fit in the corresponding groove of the push-push unit housing H to guarantee axial displacement only. The guidingrod 94 further comprises, radially between thegrooves 94a, locking recesses as first deflection faces running obliquely to thesleeve axis 90. - Equally, the
rotatable ring 95 comprises, along its outer circumference, locking recesses as second deflection faces running obliquely to thesleeve axis 90. The first and second deflection faces being circumferentially offset so as to rotate thering 95 through a predetermined angle when the guidingrod 94 or push-push driver 91 is axially displaced by a pre-determined stroke and said guidingrod 94 and push-push driver 91 come into contact through the offset deflections faces. - Indeed, when pushing the guiding rod 94 (via motor driven resetting lever system 10) or the push-push driver 91 (via manually operated connecting rod 2), the
inner protrusion 95a at the inner circumference of thering 95 pops into thelocking recess 94b and slides through the first deflection face running obliquely to the sleeve axis. This is the push-push unit locked position. - To unlock the push-push unit 9 and release the pre-stresses springs 93a and 93b, the
handle lever 3 is pushed inwards. Then, thering 95 rotates and thesprings inner protrusion 95a at the inner circumference of thering 95 out of thelocking recess 94b to the deflection face leading to thegrooves 94a for a full excursion to push thedoor handle lever 3 out. - We refer now to
figure 8 a to c showing the same handle from different angles, respectively perspective, top and rear views. One can see an embodiment with a translation extraction mechanism T where said mechanism of handle movement comprises asecond lever 7 connected by two articulated connection 801,802 to linkingrods - The two linking
rods rods oblong holes 811 close to the articulatedconnection - These oblong holes allow further pulling from ready position to unlatch the door by pulling on unlatching lever Co (
fig. 10). Figure 9 shows a rear view of a door handle according to the invention with a Bowden cable C able to act on said unlatching lever Co. The door handle bracket B is also represented. - The
figure 10 is an exploded view showing more clearly the Bowden cable V, the first and second rotations axis A6 and A7 and their associated first andsecond levers - The
figures 11 to 15 will now be used to explain the mechanism of the coupling device according to the invention applied to a translatable extractive door handle. - The
figures 11 and 12 represent the door handle 1 respectively in flush position-that is when thehandle lever 3 is co-planar with the door 100- and in ready position when thedoor handle lever 3 pops out of thedoor 100 to be grasped by a user willing to unlatch the door and open it. For each figure, on the left is a rear view and on the right, it is the corresponding front view. -
Figures 13 and 14 are respectively rear and front views-from left to right-of a door handle 1 according to the invention in ready position. Thefigure 13 shows a door handle a ready position after extraction.Figure 14 , first figure on the left, is the initial position of the connecting rod 2 (seefig. 8 for larger view). Then infigure 14 , second figure on the middle, the handle lever is being pushed as depicted on the picture on the right. In this case, we see a longitudinal displacement towards the right hand side pre-stressing the push-push unit 9 and more precisely, thesprings - Looking at
fig. 8a , the sequence is as follows: The user pushes thehandle lever 3. Since it is linked to thefirst lever 6, it creates a rotation about the first axis A6 of thefirst lever 6. Such rotation displaces the connectingrod 2 since they are linked by the slottedhole 811. Thearm 23 transmits to the connectingrod 2 the displacement, thus pushing the push-push unit 9 to pre-stress it as can be seen in the second figure in the middle offig. 14 . This is the sequence for manual push back of the door handle 1 from ready to flush position re-arming the push-push unit 9. - Once the push-push unit is pre-stressed, if a user pushes it from flush position, the
rotatable ring 95 rotates and then slides through thegrooves 94a as explained above to push thehandle 3 from flush to ready position. - It is important to note that manual push back and manual door handle extraction as explained in above sequence is performed in a totally decoupled manner with reference to the
actuator 8. Thefirst lever 6 does not rotate the cam 4. In case of electric failure, this avoids the manual back-up system to move theactuator 8 gearing mechanism. - We now refer to
figure 15 where the right hand drawing shows adoor handle lever 3 in ready position. We want thehandle lever 3 to go back to flush position electrically without any direct manual action from the user on thehandle lever 3. Such situation occurs naturally when the user locks the car and works away. However it may also occur, for instance, when the battery was empty during car park leaving thehandle lever 3 in ready position and then reloads once the problem has been solved and the engine runs because the user is driving the car. For car aerodynamics improvement as well as aesthetic reasons, the handle lever must be flush after a certain car speed. - Thanks to the invention, such retraction takes place while simultaneously re-setting the push-push unit in its pre-stressed state. To do so, one may look at the arrows of
fig. 15 andfig.2 . On the left hand side offig. 15 arrows show the clockwise rotation of the cam 4. The sequence is as follows when looking atfigure 2 andfigure 3 (zoomed view of the cam 4 and the cam lever 101): the electric motor inside theactuator 8 rotates and drives in clockwise rotation the cam 4. Such rotation pushes thecam lever 101 that in turn rotates the connectinglever 106 about theaxis 104. The clockwise rotation of the secondradial arm 106b is transmitted to the firstradial arm 106c by thecentral portion 106a of the connectinglever 106. Since the firstradial arm 106c is coupled to the push-push unit 9 via the guidingrod 94, this sequence (fig.6 ) pre-stresses thesprings - The cam 4 keeps rotating clockwise and its
chamfer 41 follows theoblique surface 101d of thecam lever 101. This deflects thecam lever 101 downwards allowing the cam 4 to go back to initial position. After deflection of thecam lever 101, aspring 102 biases back saidcam lever 101 to its initial position in the same plane as the rotation plane of the cam 4. - The coupling device according to the invention can be used for flush door handles extracting either rotationally or translatively as explained. The mere fact that the preferred embodiment is a translational flush door handle extraction shall not be considered as a limitation to such preferred embodiment. The coupling device can be adapted to fit any door requiring a flush type handle mechanism.
- A notable advantage of the push-push unit 9 according to the invention is that on one hand it can be activated and deactivated mechanically from one side and on the other hand it can be activated and deactivated electronically-via the motorized actuator 8- from the other side. Therefore, if the push-push unit is activated manually to put the
handle lever 3 in ready position, it can afterwards be reinitialized in a motorized way, i.e. set back in flush position electronically. -
