Description

Dispositif de commande de démarrage d'un véhicule automobile  Starting control device of a motor vehicle
La présente invention concerne un dispositif de commande de démarrage d'un véhicule automobile comprenant un rotor destiné à permettre le démarrage du véhicule automobile, un stator destiné à recevoir le rotor et à rester fixe par rapport audit rotor, un organe rotatif destiné à déverrouiller une partie dudit véhicule automobile et disposé entre le stator et le rotor.  The present invention relates to a motor vehicle starting control device comprising a rotor intended to allow the motor vehicle to start, a stator intended to receive the rotor and to remain fixed with respect to said rotor, a rotary member intended to unlock a motor vehicle. part of said motor vehicle and disposed between the stator and the rotor.
Usuellement, un véhicule automobile comporte un dispositif de commande de démarrage sous la forme d'un verrou comportant un rotor et un stator. Ledit verrou permet le démarrage du véhicule automobile par la mise en rotation du rotor par un moyen d'entraînement, par exemple une clé. Usually, a motor vehicle comprises a starting control device in the form of a lock comprising a rotor and a stator. Said lock enables the motor vehicle to be started by rotating the rotor by a drive means, for example a key.
Le rotor est mobile dans le stator dans typiquement trois positions angulaires. The rotor is movable in the stator in typically three angular positions.
La première position correspond à une position dite « d'arrêt » correspondant à l'arrêt du véhicule automobile. Dans cette position, ni le démarreur ni les équipements électroniques se trouvant à l'intérieur dudit véhicule ne peuvent être mis sous tension. La deuxième position correspond à une position dite « de contact » permettant la mise sous tension de certains équipements électroniques du véhicule et permettant également le déblocage d'une partie du véhicule automobile, en particulier de la colonne de direction. The first position corresponds to a so-called "stop" position corresponding to the stopping of the motor vehicle. In this position, neither the starter nor the electronic equipment inside said vehicle can be powered up. The second position corresponds to a position called "contact" enabling the powering of certain electronic equipment of the vehicle and also allowing the unlocking of a portion of the motor vehicle, in particular the steering column.
En effet, le verrou est relié à un organe rotatif formant came disposé entre le stator et le rotor de sorte que l'organe rotatif puisse être entraîné en rotation avec le rotor. Lorsque le rotor entraîne l'organe rotatif en position angulaire de contact, la colonne de direction est débloquée. Indeed, the lock is connected to a rotary cam member disposed between the stator and the rotor so that the rotary member can be rotated with the rotor. When the rotor drives the rotary member to angular position of contact, the steering column is unlocked.
Pour ce faire, l'organe rotatif est relié à un élément intermédiaire, tel qu'une tirette, permettant de débloquer un pêne formant saillie par rapport à la colonne de direction. Le déverrouillage consiste à faire sortir le pêne de la colonne de direction. Dans la position angulaire de contact, la mise sous tension de certains équipements est réalisée à l'aide de relais actionnés lorsque le rotor se met en rotation. Lesdits relais permettent de fermer un ou plusieurs circuits électroniques alimentant des équipements électroniques. To do this, the rotary member is connected to an intermediate element, such as a zipper, for unlocking a bolt projecting from the steering column. Unlocking is to lift the bolt out of the steering column. In the angular position of contact, the powering up of certain equipment is carried out using relays actuated when the rotor is rotated. Said relays make it possible to close one or more electronic circuits supplying electronic equipment.
La troisième position correspond à la position dite « de démarrage » permettant la mise sous tension du démarreur qui met en fonctionnement le moteur du véhicule automobile. Dans cette position, le démarreur est alimenté électroniquement par la batterie du véhicule automobile. Le passage du courant dans le démarreur a pour effet d'attirer et de faire avancer le noyau d'un solénoïde permettant à la fois l'alimentation en puissance du moteur électrique du démarreur et le mouvement d'un pignon mis en rotation par ledit moteur électrique. Le pignon est destiné à venir coopérer avec la roue crantée mettant en marche le moteur thermique du véhicule automobile. The third position corresponds to the so-called "start" position for energizing the starter that operates the engine of the motor vehicle. In this position, the starter is powered electronically by the battery of the motor vehicle. The passage of current in the starter has the effect of attracting and advancing the core of a solenoid allowing both the power supply of the electric motor of the starter and the movement of a pinion rotated by said motor electric. The pinion is intended to cooperate with the notched wheel starting the engine of the motor vehicle.
Lorsque le démarreur n'est plus alimenté par un courant électrique, le noyau du solénoïde recule si bien que le pignon se dégage de la roue crantée. When the starter is no longer powered by an electric current, the solenoid core moves back so that the pinion disengages from the toothed wheel.
Le diamètre de la roue crantée et celui du pignon sont très différents. Si le contact entre le pignon et la roue crantée se prolonge, la roue crantée entraînée par le moteur thermique se met à entraîner le pignon à une vitesse plus élevée que celle du démarrage. La vitesse imposée au pignon entraîne la surchauffe du moteur électrique du démarreur ce qui est dangereux et préjudiciable. The diameter of the notched wheel and that of the pinion are very different. If the contact between the pinion and the toothed wheel is prolonged, the toothed wheel driven by the heat engine starts to drive the pinion at a higher speed than the start. The speed imposed on the pinion causes the electric motor of the starter to overheat, which is dangerous and detrimental.
Le rotor du verrou entraîne en rotation l'organe rotatif généralement à l'aide d'une clavette. L'ensemble formé par le rotor et l'organe rotatif est bloqué dans la position angulaire de contact par l'intermédiaire d'une bille d'indexation montée dans l'organe rotatif et reçue dans un logement prévu dans le stator. Le logement est configuré de telle manière que l'ensemble puisse être forcé pour quitter la position angulaire de contact et passer à la position angulaire de démarrage. Pour éviter un contact prolongé entre le pignon et la roue crantée, un ressort de rappel est disposé entre l'organe rotatif et le stator amenant l'ensemble formé par l'organe rotatif et le rotor de la position angulaire de démarrage à la position angulaire de contact. The rotor of the lock rotates the rotary member generally by means of a key. The assembly formed by the rotor and the rotary member is locked in the angular contact position by means of an indexing ball mounted in the rotary member and received in a housing provided in the stator. The housing is configured such that the assembly can be forced to exit the angular contact position and move to the angular start position. To avoid prolonged contact between the pinion and the toothed wheel, a return spring is disposed between the rotary member and the stator bringing the assembly formed by the rotary member and the rotor from the angular starting position to the angular position. of contact.
Cependant, il arrive que les frottements entre la bille d'indexation et les parois du stator soient suffisamment importants pour que le retour à la position angulaire de contact ne se fasse pas. Dans ce cas, le pignon reste bloqué en contact avec la roue crantée. However, it happens that the friction between the indexing ball and the stator walls are large enough that the return to the angular position of contact does not occur. In this case, the pinion remains locked in contact with the toothed wheel.
Un but de la présente invention est donc de fournir un dispositif de commande de démarrage de véhicule automobile simple à mettre en œuvre et efficace tout en évitant l'alimentation prolongée du démarreur. An object of the present invention is therefore to provide a motor vehicle starting control device that is simple to implement and effective while avoiding the prolonged power supply of the starter.
A cet effet, selon un premier aspect, l'invention a pour objet un dispositif de commande de démarrage d'un véhicule automobile comprenant : - un rotor destiné à permettre le démarrage du véhicule automobile, ledit rotor s 'étendant suivant un axe sensiblement longitudinal et étant monté mobile en rotation selon ledit axe longitudinal, For this purpose, according to a first aspect, the invention relates to a starting control device of a motor vehicle comprising: a rotor intended to allow the motor vehicle to be started up, said rotor extending along a substantially longitudinal axis and being rotatably mounted along said longitudinal axis,
- un stator destiné à recevoir le rotor et à rester fixe par rapport audit rotor, et - un organe rotatif destiné à déverrouiller une partie dudit véhicule automobile, ledit organe rotatif étant configuré de sorte à pouvoir être entraîné en rotation avec le rotor suivant l'axe longitudinal, le dispositif étant configuré de sorte que : a stator intended to receive the rotor and to remain fixed with respect to said rotor, and a rotary member for unlocking a portion of said motor vehicle, said rotary member being configured so as to be rotated with the rotor according to the invention. longitudinal axis, the device being configured so that:
- le rotor et l'organe rotatif sont aptes à prendre une première position angulaire d'arrêt et une deuxième position angulaire de contact distincte de la position d'arrêt, the rotor and the rotary member are capable of taking a first angular stopping position and a second angular position of contact distinct from the stopping position,
- le rotor est apte à prendre en outre une troisième position angulaire de démarrage alors que l'organe rotatif reste bloqué dans la position angulaire de contact, ladite position angulaire de démarrage étant distincte des positions d'arrêt et de contact, le dispositif comprenant également un moyen de retour élastique permettant au rotor de passer de la position angulaire de démarrage à la position angulaire de contact. the rotor is capable of taking a third angular starting position while the rotary member remains locked in the angular contact position, said starting angular position being distinct from the stop and contact positions, the device also comprising resilient return means allowing the rotor to move from the starting angular position to the angular position of contact.
Le dispositif de l'invention permet de manière simple et efficace d'assurer que le rotor ne reste pas bloqué en position angulaire de démarrage. En effet, l'organe rotatif et le rotor sont découplés durant le passage de la position angulaire de contact à la position angulaire de démarrage. Seul le rotor est amené à la position angulaire de démarrage. Le moyen de retour élastique assure le retour du rotor dans la position angulaire de contact après le démarrage du moteur sans qu'un dispositif additionnel, tel qu'une bille d'indexation, n'induise des forces de frottement qui pourraient être suffisantes pour arrêter la course du rotor de sa position angulaire de démarrage à la position angulaire de contact. The device of the invention allows a simple and effective way to ensure that the rotor does not remain locked in starting angular position. Indeed, the rotary member and the rotor are decoupled during the passage from the angular position of contact to the starting angular position. Only the rotor is brought to the starting angular position. The elastic return means ensures the return of the rotor in the angular position of contact after starting the engine without an additional device, such as an indexing ball, inducing friction forces that could be sufficient to stop the rotor stroke from its starting angular position to the angular position of contact.

Comme représenté sur les figures 1 et 2, le dispositif de commande de démarrage 1 de l'invention comprend : - un rotor 3 destiné à permettre le démarrage du véhicule automobile, ledit rotor 3 s 'étendant suivant un axe 4 sensiblement longitudinal et étant monté mobile en rotation selon ledit axe longitudinal 4, As represented in FIGS. 1 and 2, the starting control device 1 of the invention comprises: a rotor 3 intended to allow the motor vehicle to start, said rotor 3 extending along a substantially longitudinal axis 4 and being mounted mobile in rotation along said longitudinal axis 4,
- un stator 5 destiné à recevoir le rotor 3 et à rester fixe par rapport audit rotor 3, et - un organe rotatif 7 destiné à déverrouiller une partie dudit véhicule automobile, ledit organe rotatif 7 étant configuré de sorte à pouvoir être entraîné en rotation avec le rotor 3 suivant l'axe longitudinal 4. a stator 5 intended to receive the rotor 3 and to remain fixed with respect to said rotor 3, and a rotary member 7 intended to unlock a part of said motor vehicle, said rotary member 7 being configured so as to be rotated with the rotor 3 along the longitudinal axis 4.
Le rotor 3 est ainsi de forme sensiblement allongé selon l'axe longitudinal 4. Ainsi, le rotor 3 peut être de forme sensiblement cylindrique. Selon le mode de réalisation représenté sur les figures 3 à 5, le rotor 3 comporte une ouverture 9 débouchant dans un logement apte à recevoir une clé actionnable par un utilisateur. Dans le mode de réalisation représenté sur les figures 1 et 2, la clé comporte typiquement une ou plusieurs pistes aptes à déplacer des paillettes 11 disposées longitudinalement dans des ouvertures prévues à cet effet dans le rotor 3 selon l'axe longitudinal 4 de ce dernier. Les paillettes 11 permettent d'empêcher l'introduction d'une clé ne correspondant pas à la combinaison des paillettes du rotor 3 et d'empêcher également la mise en rotation du rotor 3. Les paillettes 11 sont typiquement associées à des ressort 13 permettant un retour desdites paillettes dans la position n'autorisant pas la rotation du rotor 3 dans le stator 7. Selon un autre mode de réalisation, le rotor 3 peut comporter un dispositif d'entraînement, notamment automatique, activé par des signaux électroniques au lieu d'une activation mécanique engendrée par la rotation d'une clé dans le rotor. Le dispositif d'entraînement électronique peut ainsi comprendre un interrupteur de contact sur lequel l'utilisateur autorisé doit appuyer pour mettre en rotation le rotor. Dans ce cas, le rotor ne comporte pas de paillettes. The rotor 3 is thus substantially elongate in shape along the longitudinal axis 4. Thus, the rotor 3 may be substantially cylindrical in shape. According to the embodiment shown in Figures 3 to 5, the rotor 3 has an opening 9 opening into a housing adapted to receive a key operable by a user. In the embodiment shown in Figures 1 and 2, the key typically comprises one or more tracks adapted to move flakes 11 arranged longitudinally in openings provided for this purpose in the rotor 3 along the longitudinal axis 4 of the latter. The flakes 11 make it possible to prevent the introduction of a key that does not correspond to the combination of the flakes of the rotor 3 and also to prevent the rotor from rotating. The flakes 11 are typically associated with springs 13 allowing a returning said flakes to the position that does not allow rotation of the rotor 3 in the stator 7. According to another embodiment, the rotor 3 may comprise a drive device, in particular automatic, activated by electronic signals instead of a mechanical activation caused by the rotation of a key in the rotor. The electronic drive device can thus include a contact switch on which the authorized user must press to rotate the rotor. In this case, the rotor does not have flakes.
La mise en rotation de la clé dans le rotor 3 entraîne la mise en rotation dudit rotor 3 de la position d'arrêt (voir figure 3) à la position angulaire de contact (voir figure 4). The rotation of the key in the rotor 3 causes the rotation of said rotor 3 from the stop position (see FIG. 3) to the angular position of contact (see FIG. 4).
Le rotor 3 peut être relié à une pluralité de relais (non représentés) destinés à fermer un ou plusieurs circuits électroniques alimentant des équipements électroniques. Pour ce faire, un interrupteur 14 peut permettre de réaliser les contacts électriques. Les contacts électriques sont réalisés pour certains équipements électroniques, tels que la radio ou le tableau de bord, lorsque le rotor 3 est en position angulaire de contact. The rotor 3 may be connected to a plurality of relays (not shown) for closing one or more electronic circuits supplying electronic equipment. To do this, a switch 14 can make it possible to make the electrical contacts. The electrical contacts are made for certain electronic equipment, such as the radio or the dashboard, when the rotor 3 is in angular position of contact.
Le rotor 3 est également lié à un démarreur (non représenté) pour moteur destiné à mettre en fonctionnement le moteur du véhicule automobile lorsque ledit rotor 3 est en position angulaire de démarrage, comme représenté à la figure 6. The rotor 3 is also connected to a starter (not shown) for an engine intended to put the engine of the motor vehicle into operation when said rotor 3 is in angular starting position, as represented in FIG. 6.
Le stator 5 comporte un logement de forme sensiblement allongé apte à recevoir ledit rotor 3. Le stator 5 est typiquement immobile par rapport au rotor 3. Un organe rotatif 7 mobile en rotation selon l'axe longitudinal 4 dudit rotor est apte à tourner solidairement en rotation avec le rotor 3. The stator 5 comprises a substantially elongated housing adapted to receive said rotor 3. The stator 5 is typically immobile with respect to the rotor 3. A rotary member 7 movable in rotation along the longitudinal axis 4 of said rotor is able to rotate integrally in rotation with the rotor 3.
L'organe rotatif 7 peut être une came de toute forme, notamment sensiblement cylindrique. Comme représenté sur la figure 2, l'organe rotatif 7 peut être associé à un ressort 18, notamment un ressort de torsion, afin de permettre de passer de la position angulaire de contact (voir figure 4) à la position d'arrêt (voir figure 3), et inversement. The rotary member 7 may be a cam of any shape, in particular substantially cylindrical. As shown in FIG. 2, the rotary member 7 can be associated with a spring 18, in particular a torsion spring, in order to make it possible to go from the angular contact position (see FIG. 4) to the stop position (see FIG. Figure 3), and vice versa.
L'ensemble comprenant le rotor 3, le stator 5 et l'organe rotatif 7 forme un verrou. The assembly comprising the rotor 3, the stator 5 and the rotary member 7 forms a lock.
L'organe rotatif 7 est typiquement lié à un dispositif de verrouillage de la colonne de direction du véhicule automobile. Ainsi lorsque le verrou est déverrouillé soit par une clé conformé soit par un dispositif électronique d' activation, le dispositif de verrouillage libère la mobilité de la colonne de direction permettant à l'utilisateur de pouvoir agir sur les roues du véhicule automobile. The rotary member 7 is typically connected to a locking device of the steering column of the motor vehicle. Thus, when the lock is unlocked either by a shaped key or by an electronic activation device, the locking device releases the mobility of the steering column allowing the user to act on the wheels of the motor vehicle.
Ainsi, selon le mode de réalisation représenté sur les figures 1 et 2, un écran électromagnétique 21 est disposé contre une extrémité du rotor 3 lorsque ce dernier est installé dans le stator 7. Un couvercle permettant d'éviter l'arrachement du rotor 3 peut être également disposé sur le stator 5. Thus, according to the embodiment shown in FIGS. 1 and 2, an electromagnetic screen 21 is placed against one end of the rotor 3 when the latter is installed in the stator 7. A cover enabling the rotor 3 to be pulled out can also be arranged on the stator 5.
Selon l'invention, le dispositif 1 de l'invention est configuré de sorte que : According to the invention, the device 1 of the invention is configured so that:
- le rotor 3 et l'organe rotatif 7 sont aptes à prendre une première position angulaire d'arrêt (voir figure 3) et une deuxième position angulaire de contact (voir figure 4) distincte de la position d' arrêt, - The rotor 3 and the rotary member 7 are able to take a first angular position stop (see Figure 3) and a second angular position of contact (see Figure 4) separate from the stop position,
- le rotor 3 est apte à prendre en outre une troisième position angulaire de démarrage (voir figure 5) alors que l'organe rotatif 7 reste bloqué dans la position angulaire de contact, ladite position angulaire de démarrage étant distincte des positions d'arrêt et de contact, - The rotor 3 is adapted to take a third angular position of starting (see Figure 5) while the rotary member 7 remains locked in the angular position of contact, said starting angular position being distinct from the stop positions and of contact,
Le dispositif 1 de l'invention comprend également un moyen de retour élastique 18 (non représenté) permettant au rotor 3 de passer de la position angulaire de démarrage à la position angulaire de contact. The device 1 of the invention also comprises an elastic return means 18 (not shown) allowing the rotor 3 to move from the angular starting position to the angular position of contact.
Le dispositif de l'invention 1 permet de manière avantageuse de désolidariser l'organe rotatif 7 et le rotor 3 pour le passage de la deuxième position angulaire de contact à la troisième position angulaire de démarrage. Ainsi, de manière avantageuse, l'organe rotatif 7 ne peut pas être placé en position angulaire de démarrage et encore moins y être bloqué. Le rotor 3 se désolidarise de l'organe rotatif 7 lorsque l'utilisateur fait passer le rotor 3 de la position angulaire de contact à la position angulaire de démarrage. L'organe rotatif 7 reste alors dans la position angulaire de contact. The device of the invention 1 advantageously makes it possible to separate the rotary member 7 and the rotor 3 for the passage of the second angular position of contact at the third angular starting position. Thus, advantageously, the rotary member 7 can not be placed in angular start position and even less be blocked there. The rotor 3 disengages from the rotary member 7 when the user moves the rotor 3 from the angular position of contact to the angular starting position. The rotary member 7 then remains in the angular position of contact.
Le rotor 3 peut donc parcourir individuellement le passage jusqu'à la position angulaire de démarrage et revenir à la position angulaire de contact sans risque de blocage puisque le moyen de retour élastique 18 assure un tel déplacement. The rotor 3 can therefore individually traverse the passage to the starting angular position and return to the angular contact position without risk of blocking since the elastic return means 18 ensures such a displacement.
Le dispositif 1 de l'invention est ainsi efficace tout en étant simple à mettre en œuvre. The device 1 of the invention is thus effective while being simple to implement.
L'angle de rotation entre la position d'arrêt et la position angulaire de contact est typiquement compris entre 115° et 125°, notamment égale à 120°. L'angle de rotation de la position de contact à la position de démarrage est typiquement compris entre 30° et 40°, notamment égale à 35°. The angle of rotation between the stop position and the angular contact position is typically between 115 ° and 125 °, in particular equal to 120 °. The angle of rotation of the contact position at the starting position is typically between 30 ° and 40 °, in particular equal to 35 °.
Un moyen de blocage peut être configuré pour bloquer l'organe rotatif dans la position angulaire de contact afin de garantir que l'organe rotatif 7 ne passe pas dans la position angulaire de démarrage. Le dispositif 1 de l'invention peut comporter une pluralité de moyens dé blocage. Blocking means may be configured to lock the rotational member in the angular contact position to ensure that the rotary member 7 does not move into the angular starting position. The device 1 of the invention may comprise a plurality of locking means.
De manière simple, fiable et efficace, un moyen de blocage peut comporter une butée 105 appartenant au stator 5, ladite butée 105 étant apte à coopérer avec une partie saillante 107 de l'organe rotatif (voir figure 6). Ladite butée peut également appartenir à un moyen de fermeture, par exemple sous la forme d'une plaque 19 disposée à une extrémité du stator 5. Ledit moyen de fermeture peut être disposé entre l'interrupteur 14 et le stator 5. In a simple, reliable and effective manner, a locking means may comprise a stop 105 belonging to the stator 5, said stop 105 being able to cooperate with a projecting portion 107 of the rotary member (see FIG. 6). Said abutment may also belong to a closure means, for example in the form of a plate 19 disposed at one end of the stator 5. Said closure means may be disposed between the switch 14 and the stator 5.
En outre, l'organe rotatif est disposé entre le stator 5 et ledit moyen de fermeture. In addition, the rotary member is disposed between the stator 5 and said closure means.
La partie saillante 107 peut être de matière à l'organe rotatif 7 ou être rapportée sur ce dernier. La partie saillante 107 peut être de toute forme appropriée, notamment sous la forme d'une plaque ou d'un pion. La partie saillante d'un autre type de moyen de blocage peut être sous la forme d'une pièce rapportée, comme par exemple une bille 111, apte à être reçue dans un logement de réception 113b du stator en position angulaire de contact. The projecting portion 107 may be of material to the rotary member 7 or be attached thereto. The projecting portion 107 may be of any suitable form, especially in the form of a plate or a pion. The protruding portion of another type of locking means may be in the form of an insert, such as a ball 111, adapted to be received in a receiving housing 113b of the stator in angular position of contact.
Selon le mode représenté sur les figures, la bille 111 est montée dans l'organe rotatif 7 au niveau d'un logement 117 avec un moyen de retour élastique 115, tel q'un ressort de compression, permettant à la bille 111 de se rétractée dans le logement 117 pour autoriser la rotation de l'organe rotatif 7 lorsque la bille 111 est dégagée du logement 113a correspondant à la position d'arrêt pour aller vers le logement de réception 113b correspondant à la position angulaire de contact. According to the mode shown in the figures, the ball 111 is mounted in the rotary member 7 at a housing 117 with a spring return means 115, such as a compression spring, allowing the ball 111 to retract in the housing 117 to allow rotation of the rotary member 7 when the ball 111 is disengaged from the corresponding housing 113a at the stop position to go to the receiving housing 113b corresponding to the angular position of contact.
Ledit logement 113b de réception peut être configuré de sorte que sur un côté dudit logement la pièce, notamment la bille 111, peut entrer et sortir du logement lorsque l'organe rotatif 7 est mis en rotation et de l'autre côté ladite pièce bute contre la paroi du logement 113b sans pouvoir sortir de ce dernier. Ainsi, le logement de réception 113b peut être dissymétrique. Said receiving housing 113b can be configured so that on one side of said housing the part, in particular the ball 111, can enter and leave the housing when the rotary member 7 is rotated and on the other side said piece abuts against the wall of the housing 113b without being able to leave the latter. Thus, the receiving housing 113b can be asymmetrical.
Dans la configuration où le rotor 3 est activé par un dispositif d'entraînement électronique, le moyen de blocage, par exemple la bille d'indexation, et le moyen de rappel élastique, par exemple le ressort, sont disposés dans la partie activant le dispositif d'entraînement électronique, tel que l'interrupteur de contact. In the configuration where the rotor 3 is activated by an electronic drive device, the locking means, for example the indexing ball, and the elastic return means, for example the spring, are arranged in the portion activating the device. electronic drive, such as the contact switch.
L'organe rotatif 7 peut comporter un logement interne 121 apte à recevoir la trajectoire du rotor 3 de la position angulaire de contact à la position angulaire de démarrage. The rotary member 7 may comprise an internal housing 121 adapted to receive the trajectory of the rotor 3 from the angular position of contact to the angular starting position.
Le logement interne 121 peut être de toute forme permettant la réception de la trajectoire dudit rotor 3. The internal housing 121 may be of any shape allowing the reception of the trajectory of said rotor 3.
Le logement interne 121 peut également être dans une forme permettant de recevoir le rotor 3 et une pièce d'entraînement permettant au rotor 3 d'entraîner en rotation l'organe rotatif 7. La pièce d'entraînement peut être de matière avec le rotor 3 ou bien être rapportée sur le rotor 3. Le rotor 3 peut ainsi comporter comme pièce d'entraînement une excroissance d'indexation 131 apte à entraîner l'organe rotatif dans les positions d'arrêt et de contact (voir figures 3 à 5) par l'intermédiaire du ressort 18. The inner housing 121 may also be in a form for receiving the rotor 3 and a driving part allowing the rotor 3 to rotate the rotary member 7. The driving part may be made of material with the rotor 3 The rotor 3 may thus comprise, as drive part, an indexing protrusion 131 able to drive the rotary member in the stop and contact positions (see FIGS. 3 to 5) by means of FIG. through the spring 18.
Pour le sens retour de contact à l'arrêt, ladite excroissance d'indexation 131 entraîne directement l'organe rotatif. Le logement interne 121 peut être configuré de sorte à permettre une trajectoire angulaire selon un angle sensiblement égal à 35°. For the return contact direction when stopped, said indexing protrusion 131 directly drives the rotary member. The inner housing 121 may be configured to allow an angular trajectory at an angle substantially equal to 35 °.
Le moyen de retour élastique 18 permettant au rotor 3 de passer de la position de démarrage (voir figure 5) à la position angulaire de contact (voir figure 4) peut être disposé entre l'organe rotatif 7 et le rotor 3. Le moyen de retour élastique peut être par exemple un ressort de compression ou de torsion. Ainsi, avant l'introduction d'une clé apte à coopérer avec le rotor 3 dans le dispositif 1 de l'invention, le rotor 3 et l'organe rotatif 7, notamment la came, sont dans la position d'arrêt, comme illustré sur la figure 3. The elastic return means 18 allowing the rotor 3 to move from the starting position (see FIG. 5) to the angular position of contact (see FIG. 4) can be arranged between the rotary member 7 and the rotor 3. The means of springback may be for example a compression spring or torsion. Thus, before the introduction of a key capable of cooperating with the rotor 3 in the device 1 of the invention, the rotor 3 and the rotary member 7, in particular the cam, are in the off position, as illustrated. in Figure 3.
Après introduction de ladite clé dans le logement prévu à cet effet, la dite clé coopère avec les paillettes 11 de sorte à mettre en rotation le rotor 3 autour de l'axe longitudinal 4 selon un premier angle. After introduction of said key in the housing provided for this purpose, said key cooperates with the flakes 11 so as to rotate the rotor 3 about the longitudinal axis 4 at a first angle.
Selon un autre mode de réalisation, le rotor 3 est mis en rotation par activation électronique du dispositif d'entraînement électronique. According to another embodiment, the rotor 3 is rotated by electronic activation of the electronic drive device.
La rotation du rotor 3 entraîne la rotation de la came 7 autour dudit axe 4 vers la position angulaire de contact comme illustré sur la figure 4. La bille 111 se libère du logement 113a pour venir dans le logement de réception 113b. The rotation of the rotor 3 causes the cam 7 to rotate about said axis 4 towards the angular position of contact as illustrated in FIG. 4. The ball 111 is released from the housing 113a to come into the receiving housing 113b.
Dans cette position, certains équipements électroniques du véhicule automobile, comme le tableau de bord ou la radio, sont mis sous tension. A ce stade le démarreur du moteur du véhicule automobile n'est pas encore alimenté électroniquement. Dans cette position angulaire de contact, la came 7 est bloqué, notamment par des moyens de blocage sous la forme du logement de réception 113b et de la buté 105 contre laquelle une plaque 107 appartenant à la came 7 vient buter. In this position, certain electronic equipment of the motor vehicle, such as the dashboard or the radio, are energized. At this stage the engine starter of the motor vehicle is not yet electronically powered. In this angular position of contact, the cam 7 is blocked, in particular by locking means in the form of the receiving housing 113b and the stop 105 against which a plate 107 belonging to the cam 7 abuts.
La came 7 n'est donc plus mobile en rotation. The cam 7 is no longer mobile in rotation.
Si l'utilisateur continue de tourner la clé d'un angle compris entre 30° et 40° selon l'axe longitudinal 4, le rotor 3 se désolidarise de la came 7 pour tourner selon ledit angle, ladite came 7 restant dans la position angulaire de contact. If the user continues to turn the key at an angle of between 30 ° and 40 ° along the longitudinal axis 4, the rotor 3 disengages from the cam 7 to rotate at said angle, said cam 7 remaining in the angular position of contact.
Le rotor 3 vient alors se mettre dans la position angulaire de démarrage et est ensuite rappelé dans la position angulaire de contact par le moyen de retour élastique 18. The rotor 3 then comes into the angular starting position and is then returned to the angular position of contact by the elastic return means 18.
