The present invention relates to a device for controlling external opening of an automobile vehicle door. The invention relates more particularly but not exclusively to such a control device which combines an electric actuator and a mechanical actuator, suitable for triggering the opening of a lock of the automobile vehicle door.
As the external appearance of automobile vehicles has become one of the main factors of attractiveness and success, this invention relates to a device for controlling external opening of a side door of the vehicle, which is both very practical in use and has an external appearance that opens up new prospects for improving style of automobile vehicles, particularly the side style.
Generally, the control device comprises an operating plate (or gripping handle) which is hingedly mounted with respect to a body panel of the door, inside a casing. This casing is usually housed inside a cut-out provided to that end in the body panel.
A current trend is to allow opening of the door by means of an electric actuator, which is itself manually triggered, for example, by a slight pressure, a simple touch or a detection of a close presence of a user in a predefined zone of the control device, generally a non-visible internal face of the operating plate. Upon such manual actuation, an electrical control for unlocking the vehicle door is generated to the vehicle's main control unit.
For safety reasons, it is usually ensured that the door control device allows mechanical opening in the event of an electrical fault. Opening of the mechanical actuator is made with, for example, the application of a substantially higher actuating force to the operating plate, which then results in the mechanical release of the door by actuating a transmission assembly, for example a rod connected to the lock.
Such a control device is known especially from prior art, and in particular from the publication of international application WO2021/009294A1.
Such a design of the opening control device allows it to operate particularly intuitively because the motorist who wishes to open the vehicle door proceeds, in the same pulling motion, firstly to an attempt to electrically unlock the lock mechanism associated with the plate by manually triggering the electric actuator located in an internal gripping zone of the plate, and then, only if the opening of the door fails, by exerting a higher intensity tensile force on the handle. The door is then opened without any change of motion by exerting an upward oriented tensile force on the plate, which causes pivoting of the plate and mechanical actuation of the lock.
However, this prior art control device has a number of drawbacks.
First of all, it turns out to be particularly complex to mount because it comprises a large number of pieces that need to be assembled together. In addition, gripping of the plate is also of low optimisation from an ergonomic point of view because it requires the user to twist his/her wrist when he/she mechanically actuates the lock of the door.
Faced with these drawbacks, the present invention aims at further improving external opening control devices of the type under consideration. In particular, one purpose of the invention is to provide an external opening control device that is more ergonomic and simpler to assemble, while offering new perspectives in the style of the vehicle.
To this end, one object of the invention is a device for controlling external opening of an automobile vehicle door, comprising a bracket to be mounted in a cut-out in a panel of the door, a gripping handle hingedly mounted with respect to the bracket between at least one retracted rest position and a deployed open position for the mechanical actuation of a lock of the door, and wherein the bracket has a body of casing delimiting a cavity open to the outside, which the handle partially closes off in the rest position, leaving an access recess for gripping an internal face of the handle, characterised in that the handle comprises a body of generally elongate shape along a longitudinal direction having an end portion for hinging to the bracket about a hinge axis substantially parallel to the plane of the panel of the door and substantially perpendicular to the longitudinal direction of the handle.
By virtue of the invention, assembly of the device is simplified by virtue of hinging the handle to the body of the casing in an arrangement perpendicular to the longitudinal direction of the handle of the device. In particular, this facilitates the arrangement of the mechanism for actuating the lock while being more ergonomic when the handle is operated. This arrangement also provides a new style of automobile vehicle door, allowing the handle to be relatively unobtrusively integrated into its immediate environment without resorting to complex means.
In one preferred embodiment of the invention, the handle is provided with a leg for mechanically actuating the lock and extending transversely, configured to act on a transmission assembly connected to the lock.
In one preferred embodiment of the invention, the device comprises a manual control element disposed on the internal face of the handle by means of which an electrical control for the electrical actuation of the lock can be generated such that a user can proceed, in a single gripping motion of the handle, to the electrical actuation of the lock and, in case of failure, the mechanical actuation of the lock by applying a tensile stress to the handle towards the open position.
In one preferred embodiment of the invention, the device comprises a shell shaped to line the recess, the handle and the shell being configured to cooperate with each other such that the shell cannot be removed from the bracket after assembly of the handle to the bracket.
In one preferred embodiment of the invention, the cavity of the bracket is configured to impose, on the shell, an intermediate mounting and/or dismounting position passing through a final location of the handle in the cavity of the bracket.
In one preferred embodiment of the invention, the cavity and the shell are shaped to prevent the shell from being placed along a transverse direction of interlocking inside the cavity directly at a final destination position of the shell.
In one preferred embodiment of the invention, the bracket comprises a location for transversely receiving a dummy barrel piece provided with a front presentation face, the handle being configured in the bracket to cover the presentation face in the rest position.
In one preferred embodiment of the invention, the barrel piece comprises means for attaching to a side wall of the bracket.
In one preferred embodiment of the invention, the device comprises a mechanism for resisting the opening of the gripping handle from its rest position to its open position which has a hard point crossing separating at least a first trajectory part for opening the handle with high tensile stress from a second trajectory part with low tensile stress.
In one preferred embodiment of the invention, the opening resistance mechanism comprises a blocking lever movably mounted in the bracket from a configuration for blocking movement of the handle to a configuration for releasing movement of the handle, the resistance mechanism comprising means for resiliently returning the blocking lever to the blocking configuration.
In one preferred embodiment of the invention, the blocking lever comprises a cam profile and the handle comprises an actuation leg configured to act on a transmission assembly of the lock provided at an end with a follower finger cooperating along the cam profile upon application of a tensile stress to the handle.
In one preferred embodiment of the invention, the cam profile has a ramp provided with at least one inflection point defining the two trajectory parts.
In one preferred embodiment of the invention, the lever forms a reversing lever configured to pull a tensile cable of the lock, when moving to its release configuration.
In one preferred embodiment of the invention, the bracket comprises a housing for receiving and guiding the elastic means and the lever is slidably movably mounted along the longitudinal direction of the housing.
In one preferred embodiment of the invention, the bracket comprises a passageway extending from the outside to the lever into which a tool for mounting the handle can engage to temporarily move the lever against the means to allow release of movement of the handle to a mounting position.
In one preferred embodiment of the invention, the handle extends flush with the panel of the door and has an external surface which defines shape and/or appearance continuity with a surface of the panel of the door. For reasons of vehicle aerodynamics and aesthetics, the operating handle is preferably made flush with a body skin of the door panel. The door panel receiving the control device is then provided with a cavity open to the outside to allow the user to slide his/her hand behind the handle, in order to grip the inner gripping surface constituting the gripping area of the handle.
Further characteristics and advantages of the invention will become apparent in light of the following description, made with reference to the accompanying drawings in which:

In general, as can be seen in
Conventionally, the automobile vehicle 10 also comprises a door lock (not shown) typically mounted to the door 12 of the vehicle 10 and configured to be mechanically and/or electrically actuated.
In this example, the handle 22 is intended for operation of the door 14 as well as for mechanical actuation of the lock of the automobile vehicle 10. Preferably, the lock is connected to the operating handle 22 via a mechanical connection (also referred to as a transmission assembly), which will be explained in detail later, and which enables the mechanical actuation of the opening.
Generally, the opening of a door of an automobile vehicle is made by means of a lock comprising a bolt (not represented) integral with the door capable of cooperating with a striker plate (not represented) integral with the body of the vehicle. In practice, the action of releasing the bolt is known as opening the lock, which allows the door to be unhooked. Conversely, the act of keeping the bolt in the striker plate, which prohibits the door from being unhooked, is known as closing the lock.
For example, the function of the lock is to hold the door 12 of the automobile vehicle 10 in the closed position. The lock also allows the door 12 to be unhooked by an action on the external opening control device 20 which is connected to the lock and actuatable by a user. The bolt is released from the striker plate by electrical or mechanical actuation of the external opening control 20.
The opening of the lock can be made electrically with an electromechanical actuator (not represented in the figures). In this case, the actuator (not represented) comprises, for example, an electric motor, which is electrically powered by the vehicle's main electrical system. This electric motor is sized to allow the lock and door to open under normal operating conditions.
The lock is also preferably connected to a central electronic unit (not represented in the figures) for controlling locking and unlocking of the various locks fitted to the automobile vehicle 10.
In the preferred embodiment of the invention, the device 20 further comprises a barrel piece 30 having a front presentation face 30A. In the example illustrated in
In the event of an electrical failure, the lock can preferably be unlocked mechanically. To this end, in a “driver's” door configuration of the vehicle 10, conventionally, the barrel piece 30 of the device 20 is functional and is configured to allow insertion of a lock key through its presentation face 30A. As illustrated in
When the control device 20 is provided to be mounted in a so-called “passenger's” door configuration, as illustrated in
Preferably, as illustrated in
In this example embodiment, the gripping handle 22 is in the form of a generally elongate body extending in the longitudinal direction X.
As is clear from
In accordance with the invention, as is visible in
The gripping handle 22 is hingedly mounted about the geometric hinge axis with respect to the bracket 26 between at least one extreme retracted rest position and an extreme deployed open position resulting in the mechanical actuation of the opening of the lock of the door 12 resulting in the unhooking of the door 12.
In order to enable the handle 22 to be hinged, in the illustrated example, its rear side 22B includes a forked end 34 provided to be rotatably mounted about a pivot shaft of the bracket 26 (not visible in the figures).
Furthermore, in the illustrated example, on the front side 22A, the handle 22 is mechanically connected to the lock mechanism. This allows, by virtue of the operation of the handle 22, the mechanical actuation of the opening of the lock and the unhooking of the door 14.
To this end, preferably, the handle 22 comprises, on its front side 22A, a transversely extending actuation leg 36 configured to act on a transmission assembly coupled to the lock mechanism which allows the mechanical opening of the lock of the door 12. The transmission assembly comprises, for example, a tensile cable and a reversing lever 62 which will be described in more detail below.
As is clear from
Preferably, as is visible in
As illustrated in the figures, the handle 22 is arranged in the body of casing 40 to partially close off the inner cavity 48 of the body of casing 40 in the rest position such that in the illustrated example, a lower longitudinal edge of the handle 22 vertically delimits a concave clearance 50 downward, in the form of, for example, a cup or half-bowl allowing insertion of a user's hand behind the handle 22.
In the retracted position of the handle 22, the cavity 48 open to the outside is partially closed off by the handle 22 so as to make an internal face of the handle 22 accessible for gripping through the clearance 50. Indeed, when the user's hand slides into the clearance 50 of the body of casing 40, the internal face of the user's phalanges faces the inner face of the handle 22.
Alternatively, of course, the handle 22 may be arranged to close off a lower portion of the inner cavity 48 such that an upper longitudinal edge of the handle 22 vertically delimits the concave clearance upward in this case. It is also contemplatable that the handle 22 may be arranged to close off a middle portion of the inner cavity 48 such that the handle 22 vertically delimits concave clearances both upward and downward.
Preferably, in the preferred embodiment of the invention, the device 20 further comprises a lining shell 52 configured to fit snugly the clearance 50 of the open cavity 48 of the casing 40 not closed off by the handle 22 in its rest position. In this example, the shell 52 forms a finishing trim to line the part of the recess 48 of the body of casing 40 not covered by the handle 22 in its rest position.
For example, as represented in
In the illustrated example, the body of casing 40 comprises, in the longitudinal direction at one end of its first part, a location in which a bore 54 is formed, shaped to transversely house the barrel piece 30 such that the barrel 30 frontally has its presentation face 30A.
Furthermore, preferably in the so-called “passenger's” door configuration, the front end part 22A of the handle 22 is shaped to cover the presentation face 30A in the rest position of the handle 22. In the preferred embodiment of the invention, the front end part 22A of the handle 22 forms a front longitudinal extension of the handle 22 beyond a position of the actuation leg 36 of the handle 22.
In the preferred embodiment of the invention, the visual delimitation of the first and second parts of the body of casing 40 is marked by a vertical shoulder-forming step 56 visible in
Preferably, as shown in
The manual control element 100 may for example comprise, by way of non-limiting example, a gestural and/or touch detector configured to detect at least one control instruction related to a result of the gestural and/or touch detection in a control region preferably located on the internal face of the handle 22.
The detector comprises, for example, a sensor using pressure-sensitive resistor technology (also known as an FSR sensor for Force Sensing Resistor), for example using pressure-sensitive resistive inks, optical technology or capacitive technology. Such technologies are well known to the person skilled in the art and will not be described in greater detail hereafter.
By virtue of this manual control, which can be activated by a simple touch, very slight pressure or detection of the user's presence, the user can proceed, in a single gripping motion of the handle 22, to the electric unlocking of the door lock and, only in the event of failure, mechanical unlocking of the door lock by applying a tensile stress to the handle towards the open position.
In normal operation of the device 20, the handle 22 is provided to occupy its retracted rest position for the most part and to be operated only occasionally.
Thus, preferably, in order to avoid untimely movement of the handle 22 upon electrical actuation of the device 20, the device 20 further comprises a mechanism 60 for resisting the opening of the handle 22 from its rest position to its open position. The mechanism 60 comprises, for example, a hard point crossing that separates at least a first trajectory part for opening of the handle 22 with high tensile stress from a second trajectory part with low tensile stress.
In the example, the opening resistance mechanism 60 comprises a blocking lever 62 movably mounted in the body of casing 40 from a configuration for blocking the handle 22 in a retracted position to a configuration for releasing the handle 22 to its deployed position. The resistance mechanism 60 preferably comprises means 62 for elastically returning the lever to the blocking configuration.
Preferably, the blocking lever 62 comprises a cam profile 66 and the actuation leg 36 of the handle 22 is provided at an end with a follower finger 38 cooperating along the cam profile 66 (
Preferably, the cam profile 66 has a ramp provided with at least one inflection point P separating the first trajectory part with relatively higher tensile stress and a second trajectory part with relatively lower tensile stress.
Preferably, the blocking lever 62 comprises means for mechanical connection to a mechanical transmission element of the lock, such as a cable. In this case, the blocking lever 62 forms part of the mechanical transmission assembly and is configured to pull the tensile cable of the lock, when moving to its release configuration. In the example described, movement of the handle 22 to its deployed open position results in moving the lever 62 and thereby causing pulling of the cable causing unhooking of the lock.
Preferably, the bracket 26 also comprises a housing 80 for receiving and guiding the elastic return means 64 and the blocking lever 62, which is slidably movably mounted along the longitudinal direction of the housing 80. The housing 80 is in this example in the form of a generally rectangular frame extending lengthwise along the longitudinal direction of the bracket 26 on the rear wall 44. In the preferred embodiment of the invention, the actuation leg 36 of the handle 22 extends transversely inside the bracket 26 by passing through the rear wall 44 of the casing 40 so that the end of the actuation leg 36 cooperates with the resistance mechanism 60 of the handle 22 located at the rear of the casing 40 (
In particular, in
Preferably, as illustrated in
For example, advantageously, when the mounting tool 84 is a mounting screw 76 as illustrated in
The elastic return member 64 comprises a compression-operating spring in this example. In the illustrated example, the lever 62 comprises a main stud-shaped body provided with a bearing face with the spring 64. The lever 62 further comprises a cable pulling arm which is formed as an extension of the main body. For example, the arm comprises a swivel-shaped cable retaining end 63 and the bracket 26 also comprises a cable guide member 27. The lever 62 preferably comprises a longitudinally extending protrusion opposite the bearing face of the spring delimiting the ramp profile. In the illustrated example, the bearing face of the lever 62 also comprises a pin 68 for centring the spring 64.
The main operating aspects of the opening resistance mechanism 60 will now be described with reference to
The device 20 according to the invention is also distinguished from prior art by a simplicity of design allowing simple and robust assembly without the need for multiple pieces.
Indeed, in the example illustrated in
In this example, the projections 72 and complementary cavities 74 form the quick coupling means 70. However, other quick coupling means can be contemplated without departing from the scope of the invention. These quick coupling means of the two pieces (the body of the casing 40 and the panel 14) advantageously allow the two pieces to be positioned relative to each other before being attached to each other by conventional attachment means 75. This allows for easy, quick and accurate positioning of the bracket 26 when mounted to the door panel 14.
In the example illustrated in
Furthermore, preferably, the door 12 has a hole 79 in the side configured to allow access for attaching the screws 76 and 78 (
The trim shell 52 and the bracket 26 are preferably shaped to be interlocked into each other as illustrated in
Preferably, the cavity 48 of the bracket 26 is configured to impose, on the shell 52, an intermediate mounting and/or dismounting position passing through a final location of the handle 22 in the cavity 48 of the bracket 26. In the illustrated example, the shell 52 achieves an intermediate mounting position passing through the first portion of the body of casing 40 for receiving the handle 22. Consequently, once the handle 22 is positioned in the cavity 48, the shell 52 cannot be removed without passing through the location for receiving the handle 22 which is then rendered impassable by the handle 22.
Preferably, the cavity 48 and the shell 52 are shaped to prevent the shell 52 from being placed along a transverse direction of interlocking inside the cavity 48 directly into a final destination position of the shell 52.
For example, with reference to
Such an external opening control device 20 reduces the number of pieces to be supplied, handled and mounted.
Of course, the invention is not limited to the previously described embodiments. Other embodiments within the scope of the person skilled in the art may also be contemplated without departing from the scope of the invention defined by the following claims.
