EP1138853A2 - Handle for a control device to unlock a lock in an opening part of a motor vehicle - Google Patents

Abstract

The door handle incorporates a button (50) to close the supply to an electronic identification module (36) which operates in conjunction with an antenna formed by a coil round the perimeter of the door handle recess. The antenna reacts to a passive transponder worn on the driver's wrist where it will be in proximity to the antenna as the driver presses the button and grips the door handle (22). An Independent claim is also included for the vehicle having this type of handle.

Description

The present invention relates to a device for controlling the opening of a motor vehicle opening.

The invention relates for example to a device for controlling the opening of a motor vehicle door.

The invention is particularly applicable in the case of a vehicle comprising an electronic central management unit Locking and unlocking orders for the locks openings of the vehicle receiving lock orders or unlocking from an identification module of a authorized vehicle user.

Such an identification module can include an antenna fixed range carried by the vehicle which exchanges signals with a transmitter worn by the authorized user, which is for example a passive transponder, i.e. without autonomous current source, which, in response to an excitation signal from the antenna, transmits automatically an identification signal comprising in particular a identification code.

The function of the electronic central unit is to recognize the code received and, if the latter corresponds to a user's code authorized, to cause the central unlocking of different locks equipping the different openings of the vehicle.

The locks having been unlocked, the user can then then freely open one or other of the opening by conventionally acting on a handle the corresponding lock which also allows it more generally to operate the opening after opening the lock.

When the transmitter constituted by the transponder is a passive transmitter automatically activated by the antenna, this is worn by the user, for example on his wrist or in a clothing accessory, and the effective exchange distance of radio signals between the antenna and the transponder is reduced to a few tens of centimeters. So it’s only when for example the user's hand approaches the antenna carried by the vehicle that the identification module will be able to to be implemented.

The antenna does not of course emit permanently and it is necessary that the user causes its activation by a voluntary action, for example of a mechanical nature by acting on a switch.

The optimal ergonomics of such an opening device requires, to simplify the different operations, whether the antenna is activated when the user acts on the operating handle which will then be used to cause the opening of the lock and handle the opening.

The usual speed of handling a handful of operation by the user is generally very large and the reaction time of the entire system, including the station identification, then central unlocking of locks, is too long and the user may have fully manipulated the handle without it being able to control the actual opening of the associated lock.

The object of the invention is to propose a device for control of the opening of a window which allows to achieve the opening of the lock when the operation of a handle maneuver by an authorized user, even very fast, was accomplished, and in a way that is transparent to the user, without, however, allowing control of the opening of a lock which would not correspond to an operation of the handle by a authorized user.

The device according to the invention must of course allow also a command to open the lock by the user authorized in two successive maneuvers of the handle, i.e. a first maneuver leading to the unlocking of the lock then a second operation allowing the opening of the lock previously unlocked.

To this end, the invention provides a device for controlling the opening of a motor vehicle opening of the type comprising an operating handle mounted articulated relative to the opening around a fixed axis, between an extreme rest position and a extreme position of opening of the lock, and which is connected to the lock of the opening by a linkage characterized in that a intermediate lever is pivotally mounted around a fixed axis of pivoting and to which the linkage is connected, a mechanism motorized and controlled actuation being interposed between the operating handle and the intermediate lever and that is likely to occupy a first state, called inhibition, in which the operation of the handle has no effect on the lever intermediate, and a second state, called operational, in which the operation of the handle causes simultaneous operation of the intermediate lever, the mechanism, when activated for to pass from its state of inhibition to its operational state, causing the intermediate lever to move up opening the lock.

In the description which follows, identical components or similar are designated by the same reference numbers.

FIG. 1 shows a vehicle door 20 automobile which is equipped with a handle 22 intended for door operation as well as the mechanical control of the opening of a lock 24 which is illustrated schematically in dotted in Figure 1.

The operating handle 22 is of the pallet-shaped type and it is mounted articulated with respect to door 20, around a geometric axis of articulation A1, between an extreme position of rest in which it is illustrated in Figures 1, 2 and 4 and an extreme position of opening the lock 24 in which it is notably illustrated in FIG. 3.

The body of the pallet constituting the handle 22 comprises a central opening 26 facilitating gripping by hand 28 of a user.

The connection is represented diagrammatically in FIG. 1 mechanical 30 which connects, in a way which will be explained in detail thereafter, the operating handle 22 to the lock 24.

The dashed line 32 also represents the connection between the lock mechanism 24 and a central unit electronic control 34 for locking and unlocking of the various locks fitted to the vehicle.

The unit 34 comprises a module 36 for identifying a authorized user and a unit 38 for locking and central unlocking of the different locks.

An antenna 40, of known general design, is integrated into the operating handle 22. The antenna 40 is connected through a switch 42 to the identification module 36.

The switch 42 is open when the handle 22 is in its extreme rest position and it is closed when the handle maneuver 22 leaves its extreme rest position to be manipulated to its extreme open position.

When switch 42 is closed, and as we can see in FIG. 3, the antenna 40 is activated by the module 36 and is likely to exchange signals radioelectric with a transmitter 44 which is a transponder passive which is for example worn on the wrist of the hand 28 of a user authorized to access the vehicle.

The transponder 44 comprises, in a known manner, a circuit which, when activated by antenna 40, is susceptible to exchange signals with the latter and in particular to transmit towards the antenna 40, and therefore towards the module identification 36, a signal comprising an identification code of the user.

The module 36 then checks that the signal received by the antenna 40 contains a valid code and is then likely to issue orders, via line 46, to the locking unit centralized 38.

The device for controlling the opening of the door 20 also includes a button 50 for controlling the locking of the associated lock 24 or for simultaneous locking control centralized of all the locks fitted to the vehicle.

The button 50 is a manually actuated button which acts, from schematically. on a switch 52 which is normally in open position and which when the user presses it like this is illustrated in Figure 4, is closed to transmit orders to the centralized locking control unit locks through the identification module 36.

The operating principle of the system illustrated in the figures 1 to 4 is as follows.

Starting from the locked or locked position of the locks 24 illustrated in Figure 2, an authorized user approaches his hand 28 carrying the transponder 24 of door 20 and it operates the handle 22 in pivoting about its axis of articulation A1 clockwise considering the figures.

As soon as it begins to act on the handle 22, it causes the closing the switch 42 and activating the antenna 40 thus leading to the recognition of the valid code carried by its transponder 44 and the implementation of the central unlocking 38 which transmits its orders to the locks 24.

Continuing its pivoting movement on the handle operation 22, the user then wishes to cause the command mechanical opening of lock 24, previously unlocked, through the mechanical link 30.

Once this opening is completed, the user releases the operating handle 22 which is resiliently biased towards its extreme resting position.

When the user wants to lock again at least a vehicle lock, or simultaneously all the locks if the vehicle is fitted with a central locking system, he again approaches his hand 28 to the handle 22, as is illustrated in figure 4.

He then presses the button 50, without manipulating the handle 22, to cause the closure of the switch 52.

This closure has the effect of activating the antenna 40 by through the identification module 36 which recognizes the code carried by transponder 44 and which, if the code is valid, causes the various locks to be locked.

In order to give optimal ergonomics to a control of such a type, the operating handle 22 and the control mechanical opening of a lock 24 are carried out in accordance with the teachings of the invention including a first mode shown in Figure 5.

FIG. 5 shows two fixed parts 60 belonging for example to the structure of door 20 relative to which the handle 22 is pivotally mounted about the axis geometric A1, via a hinge rod 62 which crosses two parallel arms 64 and 66 belonging to the operating handle 22 and which are connected together, to constitute a rigid frame by a horizontal link bar 68 and by a lower part 69 belonging to the palette of handle operation 22.

There is shown schematically in Figure 5 a spring 70 attached to a fixed element 72 of door 20 which reminds resiliently the operating handle 22 towards its extreme position of rest, that is to say that he requests it permanently in the counterclockwise by considering Figures 5 to 11.

The operating handle 22 does not act directly on a rod 30 belonging to the mechanical connection arranged between the handle 22 and a lock 24 but it does this through a intermediate lever 74.

The lever 74 essentially consists of two arms parallels 76 which are spaced longitudinally along the axis A1, like the arms 64 and 66 of the handle 22, and each of which is hinged mounted near its free end 78 around the geometric axis A1, via the rod 62.

Thus, the operating handle 22 and the intermediate lever 74 are rotatably mounted around the same geometric axis A1, in being for example each free to pivot relative to the rod 62.

The two parallel arms 76 are interconnected by an arm longitudinal transverse 77 to constitute a lever intermediate 74 in the form of an open frame.

The mechanical connection between the operating handle 22 and the intermediate lever 74 is provided essentially by a bar 80.

The control bar 80 extends in a direction longitudinal parallel to the geometric axis A1 and therefore perpendicular to the arms 64 and 66 of the operating handle 22 and to the arms 76 of the intermediate lever 74, these arms being radial orientation with respect to the axis A1.

The control bar 80 can be actuated by a motorized mechanism 82, which will be described in detail below.

Each of the two longitudinal and opposite ends 84 of the control bar 80 is received by sliding in a slide 86 formed in an arm 76 of the intermediate lever 74.

Thus, the control bar 80 is liable to move in a direction perpendicular to its longitudinal direction relative to the intermediate lever 74 in the general plane of this last, that is to say generally in a transverse direction T with radial orientation with respect to the geometric axis A1.

Each of the slides 86 receives for example a spring helical compression 88 which permanently stresses the bar 80 sliding in the slides 86 and in the direction corresponding to its approximation to the axis A1, that is to say of the rod 62.

A section 90 of the control bar 80, located in the vicinity from one of its opposite longitudinal ends 84, towards the left considering figure 5, crosses a light of movement control which is formed in the arm 64 of the operating handle 22.

The control light 92 thus extends in a plane perpendicular to the axis of articulation A1.

The light control profile 92 with which is likely to cooperate the section 90 of the control bar 80 will be described in more detail with reference to FIGS. 6 to 11.

The motorized mechanism 82 for actuating the bar command 80, in order to cause it to move relative to the intermediate lever 74 inside the slides 86, is, in this first embodiment illustrated in Figure 5, consisting by a control cam 94. The control cam 80 is in permanently pressed against the profile -of cam 94 by the springs 88.

The control cam 94 is here a rotary cam which is mounted with free rotation on the rod 62, and which is therefore likely to rotate in both directions around the axis geometric A1 under the action of an electric motor (not shown in the figures) whose output pinion 96 cooperates with a toothed sector 98 of the cam 94, the motor receiving rotation orders in either direction sent to it by the electronic central unit 34, and more particularly by the centralized locking and unlocking unit 38 of the vehicle.

The device also includes sensors (not shown in the figures) to determine angular positions precise, and in particular the angular positions of limit switches of cam 94, which are also connected to the central unit electronic 34.

As can be seen in particular in Figure 6, the light control 92 carried by the arm 64 of the handle 22 comprises a substantially straight section 100, radially oriented by relative to the geometric axis A1, which is extended by a section control curve 102, of substantially circular concave profile but which is not centered on the A1 axis.

The control sections 100 and 102 are interconnected by a concave circular connecting section 104 which is itself centered around the axis A1.

The active part of the profile of the cam 94 which is susceptible to cooperate with the control bar 80 is constituted for essentially by a straight section 106 which is not radial orientation, i.e. the radial distance of different points of this straight section 106 with respect to the axis A1 gradually increases as one moves away radially towards outside of cam 94.

This section of active profile 106 is extended by a section convex circular 108 which is centered around the axis A1.

At its other end 109, located radially closest from the axis A1, the active section 106 is extended by a section of stop 110 which is substantially straight and substantially perpendicular to the active straight section 106.

We will now describe the different operating modes of the device in accordance with the teachings of the invention, starting from of FIG. 6 which illustrates the relative angular position of the handle 22, intermediate lever 74 and cam 94 when these components are in their initial rest position corresponding to the extreme rest position of the handle 22 and to the rest position of the cam 94.

We will assume, from the position illustrated in the figure 6, that an authorized user quickly approaches his hand 28 of the handle 22 comprising the antenna 40 and very quickly causes a complete rotation, clockwise considering the figures, of the operating handle 22 from its extreme position rest shown in Figure 6 to its extreme position mechanical opening of the lock illustrated in Figure 7.

The manipulation movement of the operating handle 22 is assumed to be fast enough to be accomplished entirely before the electronic central unit 34 causes a any implementation of the motorized mechanism 82.

During its pivoting, the handle 22 rotates around the axis A1 and the control bar 80 traverses the circular section centered on connection 104 of light 92 from its end 101 corresponding to the connection point between the sections 100 and 104 to its end 103 corresponding to the connection between sections 102 and 104.

The pivoting movement of the operating handle 22 is therefore has no effect on command bar 80 and it is also without effect on the intermediate lever 74 and therefore on the link mechanical 30 between the intermediate lever 74 and the lock 24.

From the start of their handling, the authorized user has caused the activation of the identification module 36 and therefore activation of the centralized unlocking unit 38 for locks and in particular of the lock 24 associated with the door 20.

This activation will cause the implementation of the mechanism motorized 82 which will leave its state of inhibition illustrated in Figures 6 and 7, to progressively reach a so-called state operational.

Starting from the position illustrated in Figure 7, and assuming that the user maintains his effort on the handle maneuver 22 to keep the latter in its extreme position opening, the motorized mechanism 82 is implemented and causes a clockwise rotation of the cam 94 about the axis A1.

During this rotation, the straight section 106 acts on the control bar 80, i.e. it tends gradually to radially move the latter away from to axis A1 in direction T.

However, the path of the control bar 80 in its slides 86 is not a free path, that is to say that the control bar 80 cooperates simultaneously with the active section 102 of light 92 of the operating handle 22. The bar command 80 will progressively traverse the section 102 from its end 103 corresponding to the connection between the section 102 and the circular section centered 104 to its end 99 corresponding to its connection with the straight section 100.

Combination of control bar 80 cooperation with the active section 106 of the cam 94 and the control section 102 of the light profile 92 leads to the rotation of the lever intermediate 74, around the axis A1, clockwise in considering Figures 7 and 8, and therefore to a mechanical action direct on lock 24 to gradually cause the command to open it.

Components are shown in Figure 8 in one position intermediate, and the different movements of cam 94 and intermediate lever 74 continue, clockwise of rotation, first to the position illustrated in the FIG. 9 in which the bar 80 reaches the extreme point 107, radially outermost of the active profile straight 106 and which corresponds to the connection of the latter with the convex circular section 108 of the cam 94.

FIG. 10 shows the maximum angular position that reaches the cam 94 at the end of its drive in the direction corresponding to the command to unlock the lock, that is to say the position of the operational extreme state of rotation of the cam 94.

In this position, the intermediate rotation lever 74 has reaches its maximum angular position corresponding to the opening of lock 24 and control bar 80 is opposite the start of the convex circular section 108 of the profile of the cam 94 and it is in abutment in the bottom of the light 92 corresponding to the point 99 between the active sections 100 and 102 of this last.

The motorized mechanism 82 thus caused the command to opening the lock 24 in a "transparent" manner to the authorized user, i.e. the user has content, in a conventional manner, to rotate the handle of maneuver 22 between its extreme positions, the mechanical opening of the actual lock being triggered regardless of the operating force applied to the handle 22 by the mechanism motorized 82 which acts on the control bar 80 which acts itself on the intermediate lever 74, the latter acting on the linkage 30.

If the user releases the operating handle 22, starting from the position illustrated in figure 10, and under the action return spring 70, the operating handle 22 with its arm 64 comprising the light 92 will pivot, around the axis A1, from its extreme open position illustrated in Figure 10 until its extreme rest position illustrated in FIG. 11.

During this pivoting, clockwise in considering Figures 10 and 11, the straight section 100 of the light 92 cooperates with the control bar 80 to drive the latter rotating simultaneously counterclockwise around the axis A1.

During its movement, the control bar 80 traverses the convex circular section 108 of the cam 94 and, like this last one is centered around the axis A1, the cam 94 which is then fixed in rotation does not interfere with the movements of the control bar 80.

On the other hand, the bar 80 which is trapped between the faces lights 86 parallel, simultaneously drives the lever intermediate 74 rotating counterclockwise to the rest position illustrated in FIG. 11 which corresponds, for this last, in its original rest position illustrated in Figures 6 and 7.

The release of the handle 22 by the user therefore has resulted in a new order for the mechanical closure of the lock 24.

In the position illustrated in FIG. 11, the handle 22 of maneuver is in its rest position and the motorized mechanism 82 comprising the cam 94 is in its operational state, that is to say that any new action on the operating handle 22 by any user, that is to say authorized or not, allows the control of the mechanical opening of the lock beforehand unlocked.

Indeed, a pivoting again clockwise from the handle 22 around the axis A1 causes the drive in rotation of the intermediate lever 74, clockwise by the bar command 80 on which the curved active section then acts concave 102 of light 92 to drive the control bar 80 rotating clockwise around the axis A1, the bar 80 control again traversing the convex circular section and centered 108 of the fixed cam 94.

If an authorized user wishes to provoke the central locking of the locks, he presses the button command 50.

Action on button 50, after identification of the user, causes the implementation of the motorized control 82 and therefore a new rotation of the cam command 94 counterclockwise from state shown in Figure 11.

During its counterclockwise rotation, the cam 94 has no action on the intermediate lever 74 which remains in its position illustrated in figure 11.

Indeed, during the first return phase of the cam 94 towards the inhibited state of the motorized mechanism 82, the command 80 traverses the centered circular convex profile 108 of the cam 94 then it simultaneously traverses the active section 106 of cam 94, towards the point 109 of connection between the sections 106 and 110 of the cam and the straight section radial orientation 100 of light 92.

The movements of the control bar 80 along the rectilinear stretch of radial orientation 100 lead to a displacement of the bar 80 radially inwards in direction of axis A1, but they have no action on the lever maneuver 74 because the bar 80 slides in the slides 90 radial orientation.

At the end of its counter-clockwise rotation, the cam 94 and the other components are back in position relative angular illustrated in figure 6.

Starting from Figure 6, we will now assume that the authorized user 28 acts on the operating handle 22 enough to implement switch 42 and result in recognition of the identification code by the module 36 but immediately releases the handle maneuver 22, that is to say without waiting for the implementation of the motorized device 82 and therefore without waiting for the mechanical opening lock 24.

The operating handle 22 will therefore remain, after its slackening, in its extreme position of rest illustrated in the Figure 6, while the cam 94, under the action of the central unit 38 which has been activated by the identification module 36, will be rotated clockwise so that the motorized device 82 leaves its inhibition state illustrated in the figure 6 to reach its operational state illustrated in figure 11.

During its clockwise rotation, the cam 94 causes, by its rectilinear section 106, the radial displacement towards the outside of the control bar 80 away from axis A1, in direction T, along the straight section radial orientation 100 of light 92 from end 101 up to the end 99, that is to say that the cam 94 causes only a sliding movement of the bar 80 within slides 90, this movement being without action on the lever intermediate 74.

The rotation of the cam 94 continues until the position angular illustrated in Figure 11 in which the mechanism motorized is stopped in its operational state, that is to say in a state allowing mechanical control of the opening of the lock by simple operation of the handle 22 as was previously explained with reference to Figure 11.

The design according to the invention therefore makes it possible to ensure all the different ways of handling the handle 22 aimed at leading to the opening of the lock 24 equipping the door 20.

The rectilinear section 110 of the cam 94 constitutes a stop allowing to oppose an untimely picking of the mechanism lock, i.e. it opposes any direct action on the mechanical linkage or on the intermediate lever 76 aimed at cause the latter to pivot clockwise while starting from its rest position illustrated in Figure 6 in which the cam is in its inhibition state.

Indeed, we note that any attempt to rotate the intermediate lever 74 would lead to the rotational drive clockwise from control bar 80 around axis A1 which then abuts against the straight section 110 of the cam 94, the latter being blocked in rotation in its state inhibition by the motorized mechanism 82 which is itself stopped.

The second illustrated embodiment will now be described. in Figure 12.

This embodiment differs from the first embodiment illustrated in Figure 5 by the structure of the motorized mechanism which controls the movements of the control bar 80.

The output pinion 96 of the motorized mechanism acts here on a linear actuator constituted by a screw-nut system 120 carried by the intermediate lever 74 which causes the displacements in sliding of the bar 80 in the slides 86 formed in the arms 76 of the intermediate lever 74.

Here is the central part 90 of the rod 80 which is received sliding in the slides 86 while its ends opposite longitudinal 90s are each received in a cam 94 made in the form of a groove formed in a hollow in a fixed amount 60 of door 20.

The association of a linear actuator 120 carried by the arm intermediate 74 and a double cam 94 in the form of grooves fixed corresponds to a mechanical equivalent of the rotating cam and motorized 94 illustrated in FIG. 5 and the general mode of operation of the device illustrated in figure 12 is identical to that described above with reference to FIGS. 5 to 11.
