DESCRIPTION

Control device for vehicle door lock system

The present invention is related to a control device for vehicle door lock system. It is particularly aimed at the doors of motor vehicles to drive the lock and unlock modes of door handles.

The locks implemented in this field must respond to the desired functionalities, increasingly

10 sophisticated, assuming technical tensions connected to reliability, cost and even volume. For example, vehicles are today equipped with a child safety function, a function that allows piloting the ability to open one of the rear doors when the interior handle is operated. Another function more and more found is the call of double blockade and consists in prohibiting any opening of door by means of the handles, interior or exterior. It is understood that providing a vehicle with these various blocking control features implies

15 complex means, multiplying the necessary organs in each blocking functionality the total number of pieces.

WO-A1-2009030046 discloses an attempt to rationalize a blocking system by proposing to use a single motor to operate two blocking functions. This goal is therefore not truly achieved as it continues to involve another actuator such as a key or a motor used for another locking function.

There is therefore a need to make a plurality of locking configurations limiting the complexity of the necessary means in the drive of the control parts.

The object of the invention is to alleviate all or part of the drawbacks of the techniques known to date. For this purpose, it proposes a control device for a vehicle door locking system comprising:

-a first locking control element having a mobility between a first command position and a second command position,

-a second locking control element having a mobility between a first command position and a second command position,

35 -a dragging means of the first command element and the second command element between its first command position and its second command position.

According to a characteristic aspect, the device is such that the second control element comprises a selective coupling member, said coupling element having an additional mobility relatively to the rest of the second control element between a first coupling position in which it joins kinetically the second control element and a support member of the driving means and a second coupling position in which the second control element and the first control element are kinetically connected and in which it is possible to drag the first control element by The support body. Furthermore, it advantageously comprises means for recoil of the coupling member in the second coupling position when the element

The second control unit is in the second control position and means of recoil in the first coupling position when the second control element is in the first control position.

Thus, the two control elements have coupled mobilities that allow in particular to drag them along the bias of a single motorization. In this case, the number of parts required in the operation of the mechanism, which induces a single motor and a single kinematic chain of power transmission to the two control elements, is very strongly limited.

According to a preferred case, the additional mobility of the coupling member is a rotation. The organ can thus easily move from one position to the other by tilting. Reverse means that employ at least one

The spring can be easily implemented in this embodiment. In this picture, it is advantageous that the recoil means of the coupling member comprise a torsion resort configured to exert a recoil effort towards the second coupling position when the first command element is in the second command position and a recoil effort , in the opposite direction, towards the first coupling position when the first control element is in the first control position.

60 This variant uses a single spring to perform two opposite direction reversal efforts. This is made possible by taking advantage of the translational displacement of the coupling member in the mobility of the second coupling element. This displacement modifies the relative position of the anchor points of the spring and that of the axis of rotation of the coupling member so that the direction of rotation is reversed.

65 tends to exert the force of the spring on the coupling member.

By preference, the mobility of the second command element between the first command position and the second command position is a translation. On the other hand, the mobility of the first command element between the first command position and the second command position can be equal or alternatively a translation, the translation paths of the first command element and the second command element being preferably

5 parallel

The invention may also optionally present at least one of the following characteristics:

10 - the coupling member comprises an application surface of a first support surface of the support member capable of pushing the second control element from its first control position towards its second control position, the coupling element being in its position first coupling;

-the effort exerted by the support member on the application surface is configured to oppose the effort 15 of the recoil means;

- the support member comprises a second support surface capable of pushing the first control element from its first control position to its second control position when the coupling member is in its second coupling position and that the first control element be in your second command position;

The support member comprises a third support surface capable of pushing the first control element from its second control position to its first control position, said first control element by dragging the second control element from its second control position towards its first control position, when the coupling member is in its second position;

25 - the second control element comprises a guiding zone around which the coupling member is rotatably mounted;

- the second control element comprises a contact around which the coupling member is mounted rotatably;

- an activated element comprising guiding means in translation of the contact;

- it comprises a body provided with a guiding surface of the mobilities of the first control element, the second control element and the coupling element.

The invention is also related to a vehicle door locking system comprising a control device, and to a vehicle door comprising an interior handle manageable inside a passenger compartment, an exterior handle manageable outside the passenger compartment and which It includes the locking system. The invention is

40 also refers to a vehicle equipped with at least one locking system.

By way of preference, the locking system comprises combined locking means capable of acting simultaneously on an internal handle and an external handle and dedicated locking means capable of acting only on the internal handle, the first control element activating combined lock means

45 and the second control element activating the dedicated locking means.

According to another possibility, the system comprises dedicated locking means, the first control element acting in the blocking of an external handle, the second control element acting in the blocking of an internal handle, which can be combined sequentially to act simultaneously in The two blocks.

50 The control positions are preferably the following:

-the first command position of the first command element is an unlocked position;

55 -the first command position of the second command element is an unlocked position;

-the second command position of the first command element is a locked position;

-the second command position of the second command element is a locked position.

Other features, objects and advantages of the present invention defined by the appended claims will appear upon reading the detailed description that will follow, and with respect to the attached drawings, given by way of non-limiting examples and in which:

Figure 23 is an exploded perspective view of the elements that appear in the embodiment represented in Figure 1a.

Figures 24 and 25 show a first position of the second control element and Figures 26, 27 representing a second position.

Figures 28 and 29 refer to a first position of the first control element. The latter is visible in Figures 30 and 31 in a second position.

Figure 1 shows a device according to the invention provided with a first control element 6 and an element

35 second 7 of command. In the case shown, the first control element 6 is in the form of an elongated lever capable of moving from a first position to a second position by a translation movement. Through this movement, the first control element 6 allows an organ (not shown) to be activated or inactive, which allows the actuation of a lock element and in particular a handle. The activated organ can also ensure the activation or deactivation of several lock elements and for example several handles such as an interior handle in a passenger compartment and a handle outside the passenger compartment.

The second control element 7 is partially illustrated in Figure 1 with a coupling member 10. However, in other figures and particularly in figure 12, a contact 8 forms an integral part of the second coupling element 7. Both the first element 6 and the second element 7 may be constituted by

45 a plurality of pieces being understood that the assembly of an element 6 or 7 comprises at least one mobility that allows it to be moved from a first position to a second position.

In the embodiment presented in the figures, the second element 7 is also mounted in translation to move from the first position to the second position. In particular, it is the movement followed by contact 8.

To drive the control elements 6 and 7 in their translational movement, the embodiment of the invention implements a single motorization in particular with a motor 2 of the electric micromotor type whose output shaft is coupled to an endless screw 3 which meshes on a gear sector 4 comprising a support member 5. The torque transmitted to the support member 5 allows a portion of the latter to be passed,

55 represented in the form of a support area in the different figures, in different angular positions and successively or alternatively exert forces on the control elements 6 and 7.

While one might think that a single support body 5 is incapable of performing selective controls of the two control elements 6 and 7, the invention allows several positioning configurations of the two control elements 6, 7 to be made. In particular, as will be described later in detail, the first control element 6 can be placed in the first position as the second control element 7. In another situation both the first element 6 and the second element 7 are in the second position and in a third configuration, the first element 6 is in a first position while the second element 7 is in a second position.

65 This ability to perform various combinations of position of the control elements is in particular offered

E11773724

03-13-2015

by the implementation of a localized selective coupling organ 10 and whose operating situation influences the drag phases by the support member 5.

Before describing in more detail the coupling member 10, it is indicated, in reference to Figure 2, that the body

5 1 capable of framing the assembly of the internal mechanism of the device of the invention comprises, advantageously in a central cavity or a light, different surfaces capable of guiding the movement of the pieces in particular the first control element 6, the second element 7 of control and the coupling member 10 forming part of the second control element 7. The function of each of the guiding surfaces 24 a, b, c, d, e shown in Figure 2 will be described in detail hereinafter in reference to the operating phases of the device.

Referring now to Figure 4, a coupling member 10 is shown having a substantially elongated end in the form of an arm 30 whose distal end forms a first application surface 14 capable of cooperating in certain configurations with a first surface 27 of support of support body 5. The other

15 end of the coupling member 10 has a shape that is substantially transversely oriented in the part of the arm 30 and has a rotating guidance light 16 that allows the deflection of the contact 8 that drags the activated member 11, for example, shown in the Figure 1a with the ability to rotate around a guidance zone 13. The deviation of the contact 8 in the guiding light 16 is not shown in the figures. Returning to FIG. 4, the coupling member 10 comprises at an end substantially opposite the first application surface 14 a second application surface 15 from which it will be seen that it can cooperate with a portion of the first control element 6.

Figure 5 allows to visualize the guidance offered by the body 1 in the coupling member 10. Thus, a guide pin 25 formed in the member 10 can cooperate with the guide surfaces 24 b and 24 c introduced

25 previously. A guiding zone 26 also made in the coupling member 10 is guided to the level of a surface 24 a of the body 1.

In this case, the member 10 is provided with an additional mobility relatively to the rest of the second control element 7, this additional mobility being, in the exemplary embodiment illustrated in the figures, a rotation around a rotation axis substantially defined by the contact 8. It should be noted that the contact 8 itself comprises at least one guide finger 9 presented for example in Figure 1a for its translational guidance in the activated organ 11. It is understood that the coupling member 10 can pass to the less from a first angular situation to a second angular situation. The invention takes advantage of this variable configuration of the coupling member 10 to perform different phases of operation of the whole device.

35 Reverse means are provided to return the coupling member to a desired position by default. In the example, the recoil means comprise in particular a spring and more precisely a torsion spring 17 schematized in Figures 12 to 20. One of the arms of the torsion spring 17 is anchored at the level of the mark 18 in the organ 10 of engagement while the second arm 19 is anchored at an anchor point 19 in the body 1 or another part of the device fixed relatively in the tilting of the organ 10.

The mobilities of the elements 6, 7 of the coupling member 10 are produced by the dragging of the support member 5 at the level of different surfaces where the transmission of the forces is carried out. Thus, in a first position of the coupling member 10 corresponding substantially to that of Figures 4 to 7 and Figures 12 to

45 14, the first application surface 14 may come into contact with a first support surface 27 of the support member 5. A rotation of the gear sector 4 in the clockwise direction then allows a thrust of the second control element 7 in translation from a first position corresponding to the illustrations of figures 4, 5 and 12 to a second position corresponding to the illustrations of Figures 6, 7 and 14 going through a transitory situation that appears in Figure 13.

The support member 5 further comprises a second support surface 28 which appears in particular in Figures 8 and 10 to cooperate with the first control element 6 so as to drag it from a first position corresponding to that illustrated in Figures 4 to 9 and 12 to 15 until a second position corresponding to figures 10 and 11 and even 17 and 18 not passing a transient position that appears for example in figure 16.

55 The support member 5 definitely comprises a third support surface 29, for example, visible in Figure 10 and which allows pushing, in the opposite direction to the thrust of the second support surface 28, in the first element 6 so that drag in a translation in the opposite direction to the previous one from the second position to its first position. The initial position of the first control element such as the spring of Fig. 20 is found, for example. In this phase, it should be noted that an effort is also transmitted between the first element 6 and the second element 7 so that the return thrust generated by the support member 5 in this phase also produces a return of the second element 7 so which returns to the output configuration as shown by the extreme figures of the operating cycle corresponding to figures 12 and 20. The support between the first element 6 and the second element 7 is carried out in the case illustrated through a surface

65 inside 22 on a tooth 20 projecting in the element 6 in the direction of the second element 7 which comprises as indicated above a second application surface 15 capable, when the organ 10 is tilted, of

E11773724

03-13-2015

interfere with the withdrawal path of the inner surface 22 in the tooth 20 from the second position 6 of the element to its first position. This support is particularly revealed in Figure 19 or even in Figure 10.

During all these phases, element 6 is advantageously guided by surfaces 24 d and 24 e of body 1 to operate a translation.

Figure 22 shows in isolation an embodiment of the support member 5. The three bearing surfaces 27, 28, 29 that it carries are visible. In addition, the cooperation between the support member 5 and the coupling member 10, by the bias of the first support surface 27 is detailed in Figure 21. Similarly, the second support surface 28 is illustrated in active position in Figure 21 bis, for pushing the first control element 6. In short, Figure 21b specifies the retrograde thrust generated by the third surface 29 of the support member 5, so that it moves the first control element 6 towards its first position.

The different phases of the operation procedure of the device according to the invention are now described in detail by going through Figures 12 to 20.

The configuration of figure 12 corresponds to element 6 and element 7 each in its first control position. As an example, the first command position corresponds to a deactivation command of a lock

or an unlock. In this situation, the coupling member 10 of the second element 7 is in a first angular position so that the first application surface 14 can interfere with the trajectory of the support member 5 when the motorization drives the latter in rotation in the clockwise direction (felt here purely indicative). Thus, the activation of the motor in this situation produces a right-to-left thrust of the second element 7. During this thrust, the recoil means 17 is tensioned as illustrated in Figure 13 in a translational movement phase of the item 7.

25 Returning to figure 13, the translation movement is driven and chased to the second position of the second control element 7 shown in figure 14. In this phase, the maintenance of a pair in the support member 5 makes it possible to persist the contact between the latter and the first application surface 14 of the coupling element 10. To achieve this, while in this phase the coupling member 10 is susceptible to tilting under the effect of the recoil means 17, the motor means are configured so that the stress produced at the level of the contact between the first surface 27 of support and the first surface of application 41 is in a superior norm and in the opposite direction to the recoil effort produced by the torsion spring 17.

35 On the other hand, it will be noted that, in the case of Figure 12, the relative positions of the torsion spring anchor points 18, 19 tend to rotate the coupling member 10 in a trigonometric direction, their relative positions in the case of figure 13 they have an inverse tendency to know how to rotate the coupling member 11 in a clockwise direction. This is due to the relative modification of the anchor points 18, 19 and of the tilting axis of the coupling member 10 given the translation of the contact 8 that materializes the axis of rotation of the additional mobility of the coupling member 10.

Thus, in figure 14, a second configuration of the device is reached in which the first element 6 is in the first position and the second element 7 is in its second position.

45 A supplementary configuration can be passed as shown in the link of Figures 15 to 17. In Figure 15, the motor torque has been released so that there is no longer support of the support member 5 in the susceptible coupling member 10 to oppose the effort of the torsion spring 17. Because of this, the coupling member 10 rotates around the contact 8 in a clockwise direction and the application surface 14 escapes from the rotating path of the support member 5. In this situation, and referring to Figure 8, it is noted that the second support surface 29 of the support member 5 can be applied on a corresponding surface of the first control element 6 during a supplementary rotation of the support member 5 in the direction schedule. This is illustrated in Figure 16 where the control element 6 begins to move from its first position to its second position, second position that reaches in Figure 17. In this situation, both the first element 6 and the second element 7 are in the second position. At the same time, the coupling member 10 is

55 tilted so that it is in the path of withdrawal of the element 6. It should be noted, particularly as is visible in Figure 16, that it takes advantage of the mounting on the elastic recoil means of the coupling element 10 and cooperating portions inclined in particular to the level of a front surface 21 as well as of a disengagement 23 in the tooth 20 of the element 6 so that the coupling element 10 slightly separates during the movement from right to left of the element 6.

The return to the first configuration of the device corresponding to Figure 12 is illustrated by the phases of Figures 18 to 20.

In these situations, a third support surface 29 in the support body 5 and for example visible in the figure

65 10 allows, when the motorization is reversed, to transmit the movement of the support member 5 in a trigonometric direction to the element 6 to drag it towards its first position. It is this transitional phase that appears

E11773724

03-13-2015

particularly in Fig. 19. During this movement, the second application surface 15 undergoes the stress produced by the inner surface 22 of the tooth 20 of the element 6 so that the second control element 7 is likewise dragged in a translational movement towards its first position. During this movement, given the presence of the guiding surfaces of the coupling element 10, as well as the presence of the means

5, the coupling element 10 is brought back to its first angular position. At the end, the position of figure 20 corresponding to the initial position of figure 12 is reached. In this state, the motorization can be stopped.

Thus, three different configurations of two combined control elements 6, 7 have been made thanks to this link and this by means of a single motorization and a single support body 5.

It will be noted that the controls can be inhibited by various means, in particular by blocking a mobility of an activated part, or by disengaging a kinematic transmission, the transmissions being able to operate to lock elements by all means of transmission such as rods or wires

15 Figures 1 bis and 23 to 31 show, however, a possible embodiment for certain components involved in the activation of activated elements. In this example, as shown in Figures 1 bis and 23, the first control element is intended to functionally cooperate with a pivoted activated member 32. The displacement of the activated member 32 is, if the configuration of the first control element 6 allows it, produced by an actuator 33 for the example provided with a rotating movement.

Likewise, the activated element 11 is susceptible, according to the configuration of the second control element 7, to operate a movement, such as a rotation, under the effect of an actuator 31 for example acting as a lever. Thus, figures 24 and 25 show, that in the first position of the second control element 7, the

25 actuator 31 draws the contact 8 itself kinetically attached to the activated organ 11 to transmit a movement.

On the contrary, in figures 26 and 27, the second control element is in the second position, a position in which the contact 8 is located in a widened sector 36 of the actuator 32 so that a deflection of the contact 8 is possible. deviation deactivates the effect of the actuator 31 on the activated organ 11 that does not receive movement.

The influence of the first control element 6 works in a similar manner as in the example of figures 28 to

31. In these figures, the activated organ 32 is located in a kinematic chain comprising a lever

35 actuator 33 rotating around the axis 38. The transmission member 35 is provided with a light 37 which allows it to follow the translational movement of the control member 6, and a massive end 35a which is to be interposed between the arms 33a of transmission of the lever 33 and the piece 32. When the first control element 6 reclines, the transmission member 35 accompanies it back by a recoil spring not shown.

Thus, in Figures 28 and 29, the transmission member 35 is driven in rotation by the lever 33 around the axis 38, and pushes the rotation of the part 32 in a reverse direction. The return movements of the activated organ 32 and of the lever 33 are by recoil springs not shown.

In figures 30 and 31, on the contrary, the translation of the first control element 6 and therefore of the control element 35

The transmission has released the massive end 35a of the transmission arm 33a, which consequently allows the lever 33 to be turned without dragging the activated member 32. It should be noted that during this movement, the translation of the transmission member 35 can be continued.

Of course, more than two control elements can be implemented in the device thus described. They can on the other hand form more than two command positions. The movements presented in the previous embodiment are not limiting and variants come within the scope of the present invention defined by the appended claims. In particular, the choice between mobility in rotation and in translation of the pieces is not limiting and any other combination can be considered.
