In one form, a driving mechanism and actuator lever drives the grip member between the flush and active position. When the grip member is pulled in an opening direction, the grip member drives the activation member which in turn activates the latch to unlatch the door.

Description

FIELD

The present disclosure relates to handles for a vehicle door, and more particularly to handles referred to as “flush handles.”

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Handles for vehicle doors are components having a significant influence on the style of vehicles. In this respect, vehicle manufacturers often seek to arrange the handle in the plane of the door so that it occupies a flush position also called a flush arrangement. A flush handle generally renders the handle as invisible as possible. Such flush door handles also have the advantage of reducing the aerodynamic noise caused by the rush of air as the vehicle is being driven along.

A flush handle has been proposed with a grip member and a moveable flap configured to be moved by a user to grab the grip member and pull the grip member to open the vehicle door.

Such a handle requires an arrangement with additional pieces including means for maintaining the flap so as to avoid movements of the flap when the car is moving.

Moreover, such a handle turns out inconvenient in use as the user needs to make preliminary movements to have access to the grip member.

SUMMARY

The present disclosure provides a flush handle where a flap is not needed, and wherein the preliminary movements of the user are reduced.

DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

Referring to FIGS. 1 to 8, a handle according to a first form of the present disclosure comprises a grip member 3 and an activation member 2. The handle enables a user to open a vehicle door comprising an external panel 10.

The activation member 2 is configured to activate a latch 2a. The latch 2a comprises a Bowden cable as shown in FIG. 2. In particular, the activation member 2 pulls the Bowden cable such that the door is unlatched and may be opened.

The activation member 2 is a longitudinal lever. The activation member 2 is rotationally mounted about an activation axis 20 shown in FIGS. 2 and 5.

The grip member 3 comprises a gripping part 31 and a grip lever 32a. The gripping part 31 is configured to be grasped by a user trying to open the door. The gripping part 31 is connected to the grip lever 32a.

The grip lever 32a has a first arm 34a connected to the gripping part 31 and a second arm 33a configured to cooperate with the activation member 2. The grip lever 32a is rotationally mounted about a grip axis 30.

The grip lever 32a is configured to cooperate with the activation member 2 to activate the latch 2a. In particular, the grip lever 32a comprises a cam surface 33b on which a protuberance 23b of the activation member slides such that the activation member 2 is rotated about the rotation axis 20 and activates the latch 2a.

The gripping part 31 comprises a recess configured to receive at least one or more fingers so as to be grasped. The handle is configured such that when the gripping part 31 is pulled downwardly according to reference 3b in FIG. 6, the grip lever 32a is rotated about the grip axis 30 in an opening direction, which is here a clockwise direction, in reference to FIGS. 3 and 6. As the grip lever 32a is rotated, the protuberance 23b of the activation member 2 slides on the cam surface 33b such that the activation member 2 activates the latch 2a.

The grip member 3 is movable between a flush position, an active position and an opening position.

The flush position is shown in FIGS. 1 to 3. In this position the gripping part 31 extends flush to an external panel 10 of the door. To this end, the gripping part 31 comprises an external surface substantially aligned with the external panel 10 as shown in FIGS. 1 and 3. In FIGS. 1 and 2, the external panel 10 extends along the plane of the drawing sheet.

The active position is shown in FIGS. 4 to 6. In this position the gripping part 31 projects outwardly with respect to the external panel 10 such that the grip recess is accessible by a user. This movement is shown by arrow 11a.

In addition, the grip member is configured to cooperate with the activation member 2 when put in the active position. In particular, the grip lever 32a is brought closer the activation member such that the protuberance 23b of the activation member 2 contacts the cam surface 33b, and may slide if the gripping part is actuated. To this end, as shown in FIGS. 2 and 4, the arm 33a and the cam surface 33b are shifted to the right of the figures and the cam surface 33b is placed in front of the protuberance 23b.

The opening position is shown by reference 3b in FIG. 6 and FIG. 7. The grip member 3 is configured to reach the opening position after being in the active position. In the opening position, the gripping part 31 is pulled outwardly according to the arrow 11 such that the grip lever 32a cooperates with the activation member 2 to unlatch the door.

When the gripping part 31 is moved according to an outward direction, as shown by arrow 11 in FIG. 6, so as to reach the open position shown by reference 3b, the grip lever 32a is also rotated about the grip axis 30 and the second arm 34a reaches the opening position 34b. In addition, the activation lever 2 rotates about the activation axis 20 to unlatch the vehicle door.

The handle of the present disclosure further comprises an actuator lever 4, also called “command lever” and configured to cooperate with the grip member 3 so as to drive the grip member 3 between the flush position and the active position.

In the first form, the actuator lever 4 cooperates with the grip lever 32a to drive the grip member 3 from the flush position to the active position as shown in FIGS. 1 to 6. More particularly, the actuator lever 4 is configured to push the grip lever 32a and thereby cause the gripping part 31 to project outwardly with respect to the external panel 10 of the vehicle door.

The actuator lever 4 has a central shaft 40a having two extremities, in particular an upper end and a lower end. The actuator lever 4 further comprises a driving shaft 41a and a driven shaft 42a. The driven shaft 42a is connected to the upper end of the central shaft 40a. The driving shaft 41a is connected to the lower end of the central shaft 40a.

The driven shaft 42a is configured to cooperate with the second arm 34a of the grip lever 32a to move the grip member 3 from the flush position to the active position. To this end, the actuator lever 4 is rotationally mounted about an actuator axis 40 passing through the central shaft 40a.

In one variation, the actuation lever has an inactive position 4b in which the driven shaft 42a is away from the arm 34a of the grip lever 32a.

In another variation, the grip member 3 is spring biased to move from the opening position to the active position.

In the first form, the actuator lever 4 is actuated by a motor 5 comprising a motor shaft 50 connected to the driving shaft 41.

In operation, when the grip member 3 is in the flush position, the user wanting to open the corresponding vehicle door gives information to the driving system for example by a wireless transmission through the vehicle key or the like. The motor 5 receives the information and drives the actuation lever 4 which in turn drives the grip member 3, in particular the grip lever 32a, such that the grip member 3 is moved from the flush position to the active position.

When the grip member 3 is in the active position, the user may pull the gripping part 31 according to an opening direction 11 toward the open position such that the grip member drives the activation member 2 to open the door. In this movement, the grip member is disengaged from actuator lever 4 as shown in FIG. 6, reference 3b disengaged from arm 42a of the actuator lever 4.

In one variation, the grip member 3 comprises a grip return configured to make the grip member 3 return from the opening position to the active position, and in one form, the grip return returns the grip member 3 from the opening position to the flush position.

In particular, the actuation lever 4 is configured to enable the grip member 3 to return to the flush position.

In an alternative form, the motor 5 through the actuator lever 4 could also drive the grip member 3 from the active position to the flush position 5.

According to an alternative form, the actuator lever 4 may be configured to make a clicking sound when the signal from the key or the like is received, and then the driving mechanism starts to drive the grip member from the flush position to the active position.

The clicking sound informs the user that the signal is received and that the driving mechanism is in course of making the grip member come from the flush position to the active position.

According to another alternative form shown in FIG. 8, the handle may comprise at least one activation switch 60 configured to indicate that the activation member 2 is contacting the grip member 3, in particular the arm 34a of grip lever 32a.

The activation switch 60 comprises one part 60a on the activation element 2 and at least one part 60b and 60c on the arm 34a of the grip lever 32a. The activation switch 60 is part of an activation circuit (not represented) which indicates the contact between the activation member 2 and the arm 34a.

The handle may further comprise one or more motor switches configured to indicate the rotational state of the activation member 2. To this end, the motor switches are part of a motor circuit (not represented).

The switches may also inform the driving mechanism that opening is exerted and trigger an operation of the motor in the opposite sense such that the grip member 3 may return to the flush position.

Referring to FIGS. 9 to 12, the handle according to a second form of the present disclosure is similar to the one of the first form, except the actuator lever 4 is not driven by a motor. The activation member 2 and the latch 2a of this form are not shown in detail in the figures.

The grip lever 32a has a single arm 33a connected to the gripping part 31.

In the second form, the flush position is shown in FIG. 9, the active position is shown in FIGS. 10 and 12, and the opening position is shown by reference 3b in FIG. 10. Space views of the flush and active positions are similar to FIGS. 1 and 4.

In the second form, the actuator lever 4 cooperates with the gripping part 31 to drive the grip member 3 from the flush position to the active position. More particularly, the actuator lever 4 comprises an actuator return 42 which is a spring 42, configured to drive the actuator lever 4 which in turn drives the grip member 2, in particular the gripping part 31 such that the grip member 3 from the flush position to the active position.

In this regard the actuator lever 4 comprises a driving structure 43a, which is a protuberance, and the gripping part 31 comprises a driven structure 33c which is a recess in which the driving structure 43a is engaged.

The actuator lever 4 comprises a shaft extending along and between two shafts forming a frame of the gripping part 31.

The actuator shaft is rotationally mounted about an actuator axis 40, and the grip member is rotationally mounted about a grip axis 30 substantially parallel to the actuator axis 40.

The grip member 3 is spring biased towards the flush position. A grip spring 32 is provided to this end.

In the second form, the grip member 3 is urged towards the active position by the actuator spring 42 through the actuator lever 4 and the driving and driven structures 43a and 33a. The actuator spring 42 has a force overcoming the grip spring when the actuator is driving the grip member 3.

The arrangement of the actuator lever 4 of the second form may comprised a retaining device 5a which is a bistable spring mechanism connected to the actuator lever 4 and to a bracket. The bistable spring mechanism being movable between a retaining state in which the actuator lever 4 is retained in a first position, and a releasing state in which the actuator lever 4 is released from to move to a second position.

A spring based actuator lever 4 and retaining device 5a is a mechanical arrangement of the actuator lever. Advantageously, a mechanical arrangement is usable when there is no battery in the vehicle, and a user may access the vehicle.

The actuator lever 4 is moveable between a rest position and an activating position.

The rest position is shown in FIG. 9 and in dashed lines in FIG. 10. The activating position is shown in plane lines in FIG. 10. When the actuator lever 4 moves from the rest position to the activating position, the actuator drives the gripping part 31 by driving and driven structures 43a and 33a. When the actuator lever 4 moves from the activating position to the rest position, the driving structure 43a releases the driven structure 33a such that the grip member 3 is urged by the grip spring 32 towards the flush position.

When the actuator lever 4 is in the rest position, and the gripping part 31 is pressed from outside the vehicle, the actuator lever 4 is also pressed by the drive and driving structures 33a and 43a so as to make the retaining device release the actuation lever 4 to move towards the activating position. This movement is shown by reference 4c in FIG. 9.

The actuator lever 4 further comprises a first locking structure 41a opposite to the driving structure 43a with respect to the actuator axis 40. The grip member 3 comprises a second locking structure 31a opposite to the driven structure 33a with respect to the grip axis 40.

The locking structures are configured such that when the grip member is moved from the active position to the opening position the second locking structure 31a drives the first locking structure 41a such that the actuator lever is driven towards the rest position, and presses the retaining device so as to be retained in the rest position.

FIGS. 11, 12 show the mounting of the handle of the second form. The handle comprises separate gripping part 31 and grip lever 32a. The grip lever 32a is manufactured with a handle bracket and the griping part 31 is mounted on the grip lever 31, such as for example, from outside the external panel 11 according to arrow 70a. The gripping part 31 is then fixed to the grip lever 32a for example by a screw 70.

In operation, when the grip member 3 is in the flush position, the user wanting to open the corresponding vehicle door pushes the gripping part 31 such that the driven structure 33a drives the driving structure 43a which in turn pushes the bistable spring mechanism. The actuator lever 4 is then released from the rest position and the actuator spring 42 drives the actuator lever 4 and thus the grip member 3 toward the opening position. This is made possible through the driving and driven structures 43a and 33a, and the force of the actuator spring 42 overcoming the force of the grip spring 32.

When the grip member 3 is in the active position, the user may pull the gripping part 31 according to an opening direction 11 toward the open position such that first locking protuberance 31a drives the second locking protuberance 41a so as to drive the actuator lever 4 towards the rest position, and also make the actuator lever 4 press the retaining device 5 to make the retaining device 5 retain the actuator lever 4 in the rest position. This movement is shown in FIG. 10.

With the actuator lever retained in the rest position, the grip member 3 is free to return to the flush position to the grip return 32.

Referring to FIGS. 13 to 17, the handle according to a third form of the present disclosure is a mechanical handle and has some similarities to the second form.

The grip member 3 has a plane shape with projections for a column 34 and for a locking structure 31a detailed below.

In the third form, the flush position is shown in FIGS. 14A and 14B, the active position is shown in FIGS. 15 and 16 in normal lines, and the opening position is shown by reference 3b in FIG. 16 and also FIG. 17.

In the third form, the actuator lever 4 cooperates with the grip member 3 to block the grip member 3 from the flush position. To this end, the grip member 3 comprises a first locking structure 31a and the actuator lever 4 comprises a second locking structure 41a cooperating with the first locking structure 31a.

The actuator lever 4 is moveably mounted between a locking position and an unlocking position.

In the locking position, the actuator lever 4 blocks the grip member 3 in the flush position by the locking structures 31a and 41a.

In the unlocking position, the actuator lever 4 enables the grip member 3 to move towards the active position.

The actuator return 42, which is a spring, is configured to drive the actuator lever 4 towards the locking position.

The retaining device 5 is configured to retain the actuator lever 4 in the locking position.

More particularly, the first locking structure 31a defines a first trajectory T1 when the grip member 3 is moved from the flush position to the active position, and in the locking position, the second locking structure 41a blocks the first locking structure 31a so as to block the grip member 3 in the flush position.

When the actuator lever 4 is moved to the unlocking position, the second locking structure 41a is moved out of the first trajectory T1 of the first locking structure 31a.

The grip member further comprises a driving structure 33 and the actuator lever 4 comprises a driven structure 43 cooperating with the driving structure 33 as shown in FIG. 14A. The opposite end of the actuator lever comprises the bistable spring arrangement. The driving and driven structures 33 and 43 are protuberances.

A bistable spring arrangement comprises a linear spring 51 on a first part and a retaining path 54 on a second part of the handle. The linear spring 51 may be attached to a bracket 1 of the handle and the retaining path 54 may be provided on the actuator lever 4 as shown in FIG. 14B. Alternatively, the opposite arrangement may be used as shown in FIG. 14C, i.e. the linear spring 51 is attached to the actuator lever 4 and the retaining path 54 is in the bracket 1 as shown in FIG. 14C.

The linear spring is urged between two positions in the retaining path 54 as the first and second parts are pressed with respect to each other.

More particularly, when the grip member 3 is in the flush position and the gripping part is pressed from outside the door, the driving protuberance 33 drives the driven protuberance 43 such that the actuator lever 4 presses the retaining device 5 which in turn releases the actuator lever 4 from the locking position. This movement is shown in FIG. 14A. The grip member 3 is then moved towards the active position as shown in FIGS. 15 and 16.

When the grip member is in the active position and is moved to the opening position, the first locking structure 31a cooperates with the second locking structure 41a so as to drive the actuator lever 4 along a second trajectory T2 such that the actuator lever 4 presses the retaining device 5 which in turn releases the actuator lever 4 from the unlocking position.

The actuator lever 4 comprises a shaft rotationally mounted about an actuator axis 40, and the grip member is rotationally mounted about a grip axis 30 substantially parallel to the actuator axis 40.

The grip member 3 is spring biased towards the active position. A grip spring 32 is provided to this end.

In the third form, the actuator spring 42 drives the actuator lever towards the locking position. The actuator spring 42 has a force overcoming the grip spring 32 such that the grip member remains in the flush position.

In operation, when the user pushes the grip member 3 and the bistable spring mechanism, the user overcomes the force of the actuator spring 42 such that the actuator lever 4 is moved from the locking position to the unlocking position. The actuator lever is then retained in the unlocking position by the retaining device 5. Such a retaining overcomes the force of the actuator spring 42.

With the actuator lever 4 retained in the unlocking position, the second locking structure 41a is moved out of the first trajectory T1 of the first locking structure 31a. The first locking structure is then free to move according to the first trajectory so that the grip member is moved from the flush position to the active position, by the grip return 32.

When the grip member 3 is in the active position, the user may pull the gripping part 31 according to an opening direction 11 toward the open position such that first locking protuberance 31a drives the second locking protuberance 41a according to a second trajectory 41 such that the actuator lever 4 presses the bistable spring mechanism which releases the actuator lever 4 to move towards the locking position, by the force of the actuator spring 42. This movement is shown by FIG. 16, in particular references 3b and 4d.

The grip member 3 also moves towards the flush position as the force of the actuator spring 42 overcomes the force of the grip spring 32.

When the grip member 3 is in the active position, the user may also push the gripping part 31 towards the flush position such that driving protuberance 33 drives the driven protuberance 43 and such that the actuator lever 4 presses the bistable spring mechanism which releases the actuator lever 4 to move towards the locking position, by the force of the actuator spring 42. This movement is shown by FIG. 17, in particular by movements 12 and 13.

The grip member 3 is maintained in the flush position as the force of the actuator spring 42 overcomes the force of the grip spring 32.

The present disclosure has been described above with the aid of various forms without limitation of the general concept as defined in the claims.

In particular, in the third form, the linear spring may be replaced by or work with a damper. In this case, on the actuator lever 4 the push-push function made by the bistable spring received in the retaining path is replaced by a damper. The damper may be bi-directional or mono-directional. This damper allows the actuator lever 4 to come back slowly when the handle is out to let enough time to the user to take the handle in hand.

The damper also allows the handle to not stay in the active position.

The present disclosure enables having a flush handle with:

a grip member in rotation respect to the door with a rotation axis disposed between the two ends of the grip member;

the actuator lever in contact with the handle to liberate it for extraction and pull it for retraction;

the handle spring configured for pushing out the grip member, versus extraction side;

the actuator lever allowing the deployment of the grip member when the user pushed on it from outside;

a natural blocking of the handle under external acceleration, blocked by the actuator lever;

the assembly made from outside for the lockset and the handle, there is no need to remove inner panel to disassemble them when the vehicle is finished to be assembled;

a similar ergonomy to standard grip handle;

the possibility to motorized the actuator lever;

the automatic return when user pulls the grip member to open the door when the handle has a linear spring engaging in a retaining path; and

the automatic return of the handle after having pushed it out when a damper is integrated in the handle.

Many modifications and variations will suggest themselves to those skilled in the art upon making reference to the foregoing illustrative forms, which are given by way of example only and which are not intended to limit the scope of the present disclosure, that being determined by the appended claims.

A protuberance on a first part cooperating with a recess on a second part, such that one of the parts drive the other, may alternatively be implemented with a different arrangement, i.e. one or more protuberance(s) and/or one or more recess(es) cooperating with each other where applicable.

In the claims, the word “comprising” does not exclude other elements or steps, and the indefinite article “a” or “an” does not exclude a plurality. The mere fact that different features are recited in mutually different dependent claims does not indicate that a combination of these features cannot be advantageously used. Any reference signs in the claims should not be construed as limiting the scope of the present disclosure.

The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
