Description

CONTROL DEVICE FOR VEHICLE DOOR LOCKING SYSTEM.

The present invention relates to a control device for a vehicle door locking system. It particularly deals with automotive vehicle doors to guide the locking and unlocking modes of door handles.

The locks deployed in this domain must respond to the desired functionalities, increasingly sophisticated, while taking on the technical restrictions related to reliability, cost or even the total dimensions. For example, vehicles are currently equipped with a child safety function, in which the function allows guiding the ability to open one of the rear doors when the internal handle is activated. Another function increasingly found is called double locking and consists of preventing any opening of the door by the handles, internal and external. It is understood that providing a vehicle with these various locking control features implies complex means, in which the members required for each locking feature reduce the number of total parts.

WO-A1-2009030046 discloses an attempt to rationalize a locking system by proposing the use of an exclusive engine to operate two locking functions. This objective is, however, not really achieved since it continues to involve another drive member, such as a key or an engine used for another locking function.

There is, therefore, a need to carry out a plurality of locking configurations while limiting the complexity of means necessary to guide the control parts.

The invention aims to solve all or part of the drawbacks of the techniques known to date. It proposes, for that purpose, a control device for a vehicle door locking system that includes:

- a first locking control element that has a mobility between a first control position and a second control position,

- a second locking control element

that has a mobility between i love first position in control and a second position control, - means of guidance of first element in control and the second element in control in between your first control position and your Monday position in

control,

Following a characteristic aspect, the device is such that the next control element includes a selective coupling member, wherein said coupling member has an additional mobility between a first coupling position in which it cinematically connects the second control element and a supporting member of the guiding means, and a second coupling position in which it cinematically connects the second control element and the first control element, and in which it allows the orientation member of the first control element to be guided. support. Furthermore, it advantageously includes return means of the coupling member in the second coupling position when the second control element is in the second control position, and return means in the first coupling position when the second control element control is in the first control position.

Thus, the two control elements have coupled mobilities that allow, in particular, to guide them by the tendency of a single motorization. In this case, the number of parts necessary for the operation of the mechanism is very limited, inducing a single engine and a single power transmission kinematic chain in relation to the two control elements.

Following a preferred case, the additional mobility of the coupling member is a rotation. The member can thus easily move from one position to another by tilting. The return means that employ at least one spring can be easily implanted in this modality. In this context, it is advantageous that the return means of the coupling member include a torsion spring configured to exert a return force in relation to the second coupling position when the first control element is in the second control position, and an effort of return, in the opposite direction, in relation to the first coupling position when the first control element is in the first control position.

This variant uses a single spring to carry out two efforts to return from opposite directions. 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 spring anchoring points and that of the geometric axis of rotation of the coupling member, so that the direction of rotation that tends to exert the spring force on the coupling member is reversed.

Preferably, the mobility of the second control element between the first control position and the second control position is a translation. In addition, the mobility of the first control element between the first control position and the second control position can be equally or alternatively a translation, the translation paths of the first control element and the second control element being preferably parallel.

The invention may also have, optionally, at least any of the following characteristics:

- the coupling member includes an application surface of a first support surface of the support member capable of driving the second control element from its first control position to its second control position, the coupling member being in its first position coupling;

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

- the support member includes a second support surface capable of driving 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 control is in its second control position;

the support member includes a third support surface capable of driving the first control element from its second control position to its first control position, wherein said first control element guides the second control element from its second control position. control to its first control position, when the coupling member is in its second position;

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

- the second control element comprises a pin around which the coupling member is pivotally mounted;

- a controlled element comprising means for directing the translation of the pin;

- it includes a body with a guide surface for the mobility of the first control element, the second control element and the coupling member.

The invention also relates to a vehicle door locking system comprising a control device, and a vehicle door comprising an internal handle maneuverable from the inside of a compartment, an external handle maneuverable from the outside of the compartment and which includes the locking system. The invention also relates to a vehicle with at least one locking system.

Preferably, the locking system comprises combined locking means capable of acting simultaneously on an internal handle and on an external handle, and dedicated locking means capable of acting exclusively on the internal handle, where the first locking element is used. control controls the combined locking means and the second control element controls the dedicated locking means.

Following another possibility, the system comprises dedicated locking means, in which the first control element acts on the locking of an external handle, and the second control element which acts on the locking of an internal handle, can be combined sequentially to act simultaneously on the two locks.

The control positions are preferably those described below:

the first control position of the first control element is an unlocked position, the first control position of the second control element is an unlocked position, the second control position of the first control element is a locked position, the second control position of the second control element is a locked position.

At Figures 28 and 29 if refer to a first position of first element in control . That last is visible in Figures 30 and 31 in an Monday position • THE Figure 1 show one device according The

invention with a first control element 6 and a second control element 7. 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 movement of translation. By this movement, the first control element 6 allows to make active (inactive) a member (not shown) that allows the actuation of a lock element and, in particular, a handle. The controlled member can, in addition, guarantee the activation or deactivation of several lock elements and, for example, several handles, such as a handle internal to a compartment and a handle external to the compartment.

The second control element 7 is partially illustrated in Figure 1 with a coupling member 10. However, in relation to other Figures and notably in relation to Figure 12, a pin 8 is an integral part of the second coupling element 7. Both the the first element 6 and the second element 7 can be made up of a plurality of parts, it being understood that the assembly of an element 6 or 7 includes, at least, a mobility that allows it to pass from a first position to a second position.

In the embodiment shown in the Figures, the second element 7 is also mounted in translation to pass from the first position to the second position. In particular, this is the movement followed by pin 8.

To guide the control elements 6 and 7 in their translation movement, the modality of the invention implements a single motorization, in particular with a motor 2 of the electric micromotor type in which the output shaft is coupled to a worm screw 3 that it engages over a gear sector 4, which comprises a support member 5. The binary motor transmitted to the support member 5 allows the passage of a portion of the latter, represented in the form of a support zone over the different Figures, in different angular positions and to exercise successively or alternatively the efforts on the control elements 6 and 7.

Although it can be thought that a single support member 5 is unable to carry out selective commands of two control elements 6 and 7, the invention allows to carry out several positioning configurations of two control elements 6, 7. In particular, as will be described in further details further ahead, the first control element 6 can be placed in the first position in the same way 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.

This ability to perform various combinations of position of the control elements is offered, in particular, by the implantation of a referenced selective coupling member 10 and whose operating situation influences the orientation phases by the supporting member 5.

Before describing in greater detail the coupling member 10, it is indicated, with reference to Figure 2, that the body 1 capable of delimiting the assembly of the internal mechanism of the device of the invention includes, advantageously in a central cavity or an orifice, different surfaces able to direct the movement of the parts, in particular the first control element 6, the second control element 7 and the coupling member 10 that is part of the second control element 7. The function of any of the guiding surfaces 24 a, b, c, d, and represented in Figure 2 will be described in detail below, with reference to the operating phases of the device.

Referring now to Figure 4, there is shown a coupling member 10 which has a substantially elongated end in the form of an arm 30, the distal end of which forms a first application surface 14 capable of cooperating in certain configurations with a first surface support member 27 of the support member 5. The other end of the coupling member 10 has a shape oriented substantially transversely with respect to the arm part 30, and has a rotating direction hole 16 that allows the pin 8 to be displaced which tilts the controlled member 11 shown, for example, in Figure 1 bis with the ability to rotate around a targeting zone 13. The displacement of pin 8 in targeting hole 16 is not shown in the Figures. Back to Figure 4, the coupling member 10 includes, at an end substantially opposite the first application surface 14, a second application surface 15 on which it is realized that it can cooperate with a portion of the first control element 6.

Figure 5 allows to visualize the direction offered by the body 1 on the coupling member 10. Thus, a steering rod 25 formed on the member 10 can cooperate with the previously introduced guidance surfaces 24 b and 24 c. A targeting zone 26 also realized on the coupling member 10 is guided at the level of a surface 24 a of the body 1.

The member 10 is, in the case shown, provided with an additional mobility in relation to the rest of the second control element 7, this additional mobility being, in the embodiment shown in the Figures, a rotation around a substantially defined geometric axis of rotation by pin 8. Note that pin 8 itself includes at least one targeting finger 9 shown, for example, in Figure 1 bis for its translation in the controlled member 11. It is understood that the coupling member 10 can pass from at least 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 stages of operation of the assembly of the device.

The return means are provided to return the coupling member to a desired position for standard. In the example, the return means in particular include a spring and more precisely a torsion spring 17 outlined in Figures 12 to 20. One of the arms of the torsion spring 17 is anchored at the level of frame 18 on the coupling member 10 while the second arm 19 is anchored at an anchor point 19 on the body 1 or another part of the device fixed in relation to the tilting of the member 10.

The mobilities of the elements 6, 7 of the coupling member 10 are produced by orienting the supporting member 5 at the level of different surfaces on which the transmission of forces takes place. Thus, in a first position of the coupling member 10 which corresponds substantially to that of Figures 4 to 7 and Figures 12 to 14, the first application surface 14 can come into contact with a first support surface 27 of the support member 5. A clockwise rotation of the gear sector 4 then allows an impulse of the second control element 7 in translation from a first position corresponding to the illustrations in Figures 4, 5 and 12 to a second position corresponding to the illustrations in Figures 6, 7 and 14 when going through a transitory situation that appears in Figure 13.

The support member 5 further includes a second support surface 28 which appears, in particular, in Figures 8 and 10 to cooperate with the first control element 6, in order to orient 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 still 17 and 18 when passing through a transitional position that appears, for example, in Figure 16.

The support member 5 finally includes a third support surface 29, for example, visible in Figure 10 and that allows to push, in the opposite direction to the impulse of the second support surface 28, on the first element 6, in order to orient in a translation of the opposite direction to the previous one, from the second position to its first position. Thus, the initial position of the first control element is resumed, such as that of the spring of Figure 20, for example. In this phase, it is noted that an effort is, moreover, transmitted between the first element 6 and the second element 7, so that the return impulse obtained by the support member 5 in this phase also produces a return of the second element 7 of in order to return to the starting configuration, as shown in 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 by means of an internal surface 22 on a tooth 20 projecting over element 6 towards the second element 7 which includes, as previously indicated, a second application surface 15 able to interfere, when the member 10 is tilted, with the retraction path of the inner surface 22 on tooth 20, from the second position of element 6 to its first position. This support is notably shown in Figure 19, or in Figure 10.

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

Figure 22 shows an embodiment of the support member 5 in isolation. The three support surfaces 27, 28, 29 that bear the same are visible. In addition, the cooperation between the support member 5 and the coupling member 10, due to the tendency of the first support surface 27, is detailed in Figure 21. Similarly, the second support surface 28 is illustrated in an active position in Figure 21 bis, to drive the first control element 6. Finally, Figure 21 needs the retrograde impulse obtained by the third surface 29 of the support member 5, in order to move the first control element 6 to its first position.

The different stages of the operation process of the device according to the invention are now described in detail when going through Figures 12 to 20.

The configuration in Figure 12 corresponds to element 6 and element 7, each in its first control position. As an example, the first control position corresponds to a control for deactivating 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 path of the support member 5 when the motorisates the latter in a clockwise rotation ( purely indicative here). Thus, the activation of the motor in this situation produces an impulse from the right to the left of the second element 7. During this impulse, the return means 17 is placed under tension, as illustrated in Figure 13, in a phase of the element's translation movement 7.

Referring to Figure 13, the translation movement is carried out and continues until the second position of the second control element 7 represented in Figure 14. In this phase, the retainer of a torque on the support member 5 allows the contact between that the last and the first application surface 14 of the coupling element 10. In order to achieve this objective, while in this phase the coupling member 10 is susceptible to tilting under the effect of the return means 17, the motor means are configured so that the effort produced at the level of contact between the first support surface 27 and the first application surface 14 is, in general, higher, and in the opposite direction to the return effort produced by the torsion spring 17.

It is also noted that, while in the case of Figure 12 the relative positions of the anchor points 18, 19 of the torsion spring 17 tend to rotate the coupling member 10 in a trigonometric direction, their relative positions in the case of Figure 13 have an inverse tendency, namely, to rotate the coupling member 11 in a clockwise direction. This is due to the relative modification of the anchoring points 18, 19 and the tilting geometric axis of the coupling member 10 due to the translation of the pin 8 that materializes the geometric axis of rotation of the additional mobility of the coupling member 10.

Thus, in Figure 14, a second device configuration is achieved in which the first element 6 is in the first position and the second element 7 is in its second position.

You can move on to an additional configuration as shown in the sequence of Figures 15 to 17. In Figure 15, the binary motor has been so freed that it no longer has the support member 5 over the coupling member 10 susceptible to oppose the stress of the torsion spring 17. In this way, the coupling member 10 rotates around the pin 8 in a clockwise direction and the application surface 14 escapes the rotating path of the support member 5. In this situation, and when 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 at the time of an additional rotation of the support member 5 in a clockwise direction. This is illustrated in Figure 16, where the control element 6 starts to move from its first position to its second position, the second position that is reached in Figure 17. In this situation, both the first element 6 and the second element 7 are in your second position. At the same time, the coupling member 10 is tilted so well that it is on the retraction path of element 6. It is noted, notably as shown in Figure 16, that it is possible to take advantage of the assembly on return means elasticity of the coupling element 10 and of inclined cooperative portions, in particular, at the level of a front surface 21, as well as a deviation 23 on the tooth 20 of the element 6 so that the coupling element 10 wears slightly at the moment of the movement of advance from right to left of 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 located on the support member 5 and, for example, visible in Figure 10 allows, when the motorization is inverted, to transmit the movement of the support member 5 in a trigonometric direction to the element 6 to guide the same until its first position. It is this transitional phase that appears notably in Figure 19. During this movement, the second application surface 15 is subjected to the stress produced by the internal surface 22 of tooth 20 of element 6, so that the second control element 7 is also oriented in a translation movement to its first position. During this movement, due to the presence of the guiding surfaces of the coupling element 10, as well as the presence of the return means, the coupling element 10 is returned to its first angular position. At the end, the position of Figure 20 is reached, which corresponds to the initial position of Figure 12. In this state, the motorization can be ended.

Thanks to this sequence, three different configurations of two control elements 6, 7 are combined, using a single motor and a single support member 5.

It will be noted that the controls can be inhibited by various means, in particular by blocking the mobility of a controlled part, or by clutching a kinematic transmission, the transmissions in relation to the lock elements can be operated by any means of transmission, such as bars or cables.

Figures 1 bis and 23 to 31 show, however, a possible modality for certain components that participate in the actuation of controlled elements. In this example, as shown in Figures 1 bis and 23, the first control element is intended to functionally cooperate with a pivoting controlled member 32. The displacement of the controlled member 32 is, if the configuration of the first control element 6 permits, produced by an actuator 33 for the example provided with a rotary movement.

In addition, the controlled element 11, according to the configuration of the second control element 7, is capable of operating a movement, such as a rotation, under the effect of an actuator 31, for example, which acts according to a lever. Thus, Figures 24 and 25 show that in the first position of the second control element 7, the driver 31 guides the pin 8 cinematically connected to the controlled member 11 to transmit a movement to it.

On the contrary, in Figures 26 and 27, the second control element is in the second position, in which the pin 8 is located in an enlarged sector 36 of the driver 32 at the moment when a displacement of the pin 8 is authorized. This displacement deactivates the effect of the driver 31 on the controlled member 11 that does not receive movement.

The influence of the first control element 6 operates in a similar manner, as in the example of Figures 28 to 31. In these Figures, the controlled member 32 is located in a kinematic chain that includes a driving lever 33 in rotation about the geometric axis 38. The transmission member 35 is provided with an orifice 37 that allows it to follow the translation movement of the control member 6, and with a massive end 35a that interposes between the transmission arm 33a of the lever 33 and the part 32. When the first control element 6 moves away, the transmission member 35 accompanies it in return by a return spring (not shown).

Thus, in Figures 28 and 29, the transmission member 35 is oriented in rotation by the lever 33 around the geometric axis 38, and drives the rotation of the part 32 in an inverse direction. The return movements of the controlled member 32 and the lever 33 are guaranteed by return springs (not shown).

In Figures 30 and 31, on the contrary, the translation of the first control element 6 and, therefore, of the transmission member 35 releases the massive end 35a of the transmission arm 33a, allowing the lever 33 to rotate, as a consequence, without orienting the member controlled 32. Note that, at the moment of this movement, the translation of the transmission member 35 can be followed.

Clearly, more than two control elements can be implemented in the device so described. They can also form more than two control positions. The movements shown in the preceding modality are not limiting and the variants are within the scope of the present invention. In particular, the choice between rotational and translational mobility of parts is not limiting, and any other combination can be envisaged.
