Description

La présente invention se rapporte à une clé pour véhicule automobile comprenant un boitier de clé amélioré, en particulier à une clé comprenant une un système anti-écartement du boitier de clé.The present invention relates to a key for a motor vehicle comprising an improved key box, in particular to a key comprising an anti-spreading system of the key box.

De manière générale, les clés pour véhicule automobile se présentent sous forme de clés électroniques comprenant un circuit électronique imprimé identifiant un utilisateur autorisé d'un véhicule automobile afin de verrouiller et/ou déverrouiller un ouvrant du véhicule. En outre, de telles clés sont usuellement pourvues d'une clé de secours mécanique, configurée pour être insérée dans un logement d'un ouvrant pour commander un verrou de l'ouvrant afin de le verrouiller et/ou déverrouiller mécaniquement. Ainsi, ces clés permettent de verrouiller et/ou déverrouiller un véhicule automobile soit électroniquement, à distance, soit mécaniquement, manuellement.In general, motor vehicle keys are in the form of electronic keys comprising a printed electronic circuit identifying an authorized user of a motor vehicle in order to lock and/or unlock an opening of the vehicle. In addition, such keys are usually provided with a mechanical emergency key, configured to be inserted into a housing of an opening to control a lock of the opening in order to lock and/or unlock it mechanically. Thus, these keys make it possible to lock and/or unlock a motor vehicle either electronically, remotely, or mechanically, manually.

Il existe également des clés pour véhicule automobile comprenant uniquement une clé mécanique.There are also motor vehicle keys comprising only a mechanical key.

Une clé mécanique comprend de manière connue une lame de clé, également nommée insert, solidaire d'une tête de clé. La tête de clé est généralement mobile en rotation dans un boitier de clé, afin de passer d'une position de repos dans laquelle la lame de clé est en position rétractée dans le boitier de clé, à une position de verrouillage/déverrouillage dans laquelle la lame de clé est en position déployée en saillie du boitier de clé. A cet effet, elle comprend une tête de clé, disposée à une extrémité de la lame de clé, qui est retenue dans le boitier de clé de sorte à être mobile en rotation selon un unique axe de rotation généralement transversal au boitier de clé.A mechanical key comprises in known manner a key blade, also called an insert, integral with a key head. The key head is generally rotatable in a key case, in order to pass from a rest position in which the key blade is in the retracted position in the key case, to a locking/unlocking position in which the key blade is in the deployed position projecting from the key case. To this end, it comprises a key head, arranged at one end of the key blade, which is retained in the key case so as to be rotatable along a single axis of rotation generally transverse to the key case.

Lors du verrouillage/déverrouillage manuel du véhicule, la lame de clé, disposée en saillie du boiter de clé, est insérée dans une serrure et un couple lui est appliqué afin d'actionner un verrou de la serrure. La valeur du couple est variable en fonction du type de clé, de la température, des conditions climatiques, de l'usure du système de verrouillage, de la cinématique du système de verrouillage ou encore de la manière d'utilisation de la clé par un utilisateur.During the manual locking/unlocking of the vehicle, the key blade, arranged projecting from the key box, is inserted into a lock and a torque is applied to it in order to actuate a bolt of the lock. The value of the torque is variable depending on the type of key, the temperature, the climatic conditions, the wear of the locking system, the kinematics of the locking system or even the way in which the key is used by a user.

Le boitier de clé dans lequel est insérée la tête de clé, comprend usuellement deux capots de clé emboîtés l'un dans l'autre. Les documents DE 10 2010 060317 A1 ou DE 10 2012 018444 A1 divulguent chacun une telle clé de véhicule automobile. En outre, d'autres composants de la clé sont insérés dans le boitier de clé, comme par exemple un circuit imprimé pour former une clé électronique. De manière générale, un tel emboîtement est suffisant pour maintenir le boitier de clé fermé dans la mesure où le couple appliqué pour un verrouillage/déverrouillage manuel est modéré. Cependant, dans le cas où le couple appliqué est trop important et/ou dans le cas où l'emboitement est fragilisé par le temps, le boitier de clé est susceptible de s'ouvrir. En effet, la tête de clé ne peut plus supporter le couple appliqué pour le verrouillage/déverrouillage, ce qui entraine l'ouverture du boitier de clé.The key box in which the key head is inserted usually comprises two key covers fitted one inside the other. The documents DE 10 2010 060317 A1 Where DE 10 2012 018444 A1 each disclose such a motor vehicle key. In addition, other components of the key are inserted into the key box, such as for example a printed circuit to form an electronic key. In general, such an interlocking is sufficient to keep the key case closed insofar as the torque applied for manual locking/unlocking is moderate. However, in the case where the torque applied is too high and/or in the case where the fitting is weakened by time, the key box is likely to open. Indeed, the key head can no longer support the torque applied for locking/unlocking, which causes the opening of the key box.

Plus particulièrement, dans certains modes de réalisation, la tête de clé est prise en sandwich dans un palier de retenue configuré pour autoriser la rotation de la tête de clé selon un unique axe de rotation et pour bloquer un mouvement axial de la tête de clé. Ainsi, le palier de retenue est un boitier intermédiaire pour la tête de clé. Il permet de dissocier le boitier de clé de la fonction de retenue de la tête de clé. Ainsi le boitier de clé a une fonction principalement esthétique.More particularly, in some embodiments, the key head is sandwiched in a retaining bearing configured to allow rotation of the key head about a single axis of rotation and to block axial movement of the key head. Thus, the retaining bearing is an intermediate box for the key head. It separates the key box from the key head retaining function. Thus the key box has a mainly aesthetic function.

Comme illustré à la figure 1, une telle clé 200' de l'art antérieur comprend un boitier de clé 100' comprenant un premier capot de clé 102' et un deuxième capot de clé 104' configurés pour être emboîtés. Dans le boitier de clé 100', sont disposés une tête de clé 12' solidaire d'une lame de clé 14'. Dans l'exemple représenté, la tête de clé 12' est prise en sandwich dans un palier de retenue 16' permettant de maintenir la tête de clé. Le palier de retenue 16' comprend un capot intermédiaire 18' et un support 20' configurés pour être emboîtés.As shown in figure 1 , such a key 200' of the prior art comprises a key box 100' comprising a first key cover 102' and a second key cover 104' configured to be interlocked. In the key box 100', a key head 12' secured to a key blade 14' is arranged. In the example shown, the key head 12' is sandwiched in a retaining bearing 16' allowing the key head to be held. The retaining bearing 16' includes an intermediate cover 18' and a support 20' configured to be interlocked.

La figure 1 montre que lorsque la clé 200' est insérée dans un verrou 300, et qu'un couple C lui est appliqué, le palier de retenue 16' et le boitier de clé 200' peuvent s'ouvrir, notamment en cas d'usure, ou lors de l'application d'un couple important.The figure 1 shows that when the key 200' is inserted into a lock 300, and a torque C is applied to it, the retaining bearing 16' and the key box 200' can open, in particular in the event of wear, or when applying a large torque.

Il est donc nécessaire de fournir une clé améliorée dans laquelle le boitier de clé et/ou le palier de retenue ne s'ouvre(nt) pas avec le temps, l'usure, ou lors de l'application d'un couple important.There is therefore a need to provide an improved key in which the key housing and/or the retaining bearing does not open with time, wear, or upon the application of a large torque.

A cet effet, l'invention a pour objet une clé de véhicule automobile comprenant:

  • Une tête de clé solidaire d'une lame de clé longitudinale, la tête de clé étant mobile en rotation selon un axe de rotation entre une position de verrouillage/déverrouillage et une position de repos,
  • Un boitier de clé comprenant un premier capot de clé et un deuxième capot de clé destinés à être disposés de part et d'autre de la tête de clé et configurés pour s'emboiter pour emprisonner la tête de clé et autoriser sa rotation selon l'axe de rotation, et
  • un système anti-écartement du boitier de clé configuré pour empêcher l'écartement du boitier de clé.
To this end, the subject of the invention is a motor vehicle key comprising:
  • A key head secured to a longitudinal key blade, the key head being rotatable along an axis of rotation between a locking/unlocking position and a rest position,
  • A key box comprising a first key cover and a second key cover intended to be arranged on either side of the key head and configured to fit together to imprison the key head and allow its rotation according to the axis of rotation, and
  • an anti-spread system of the key shell configured to prevent the separation of the key shell.

Ainsi, le système anti-écartement permet d'empêcher l'ouverture du boitier de clé lors de l'application d'un couple sur la clé afin de verrouiller/déverrouiller un verrou.Thus, the anti-spreading system makes it possible to prevent the opening of the key case during the application of a torque to the key in order to lock/unlock a lock.

La position de verrouillage/déverrouillage est une position dans laquelle la lame de clé est en position déployée en saillie du boitier de clé, et la position de repos est une position dans laquelle la lame de clé est en position rétractée dans le boitier de clé.The locking/unlocking position is a position in which the key blade is in the deployed position projecting from the key case, and the rest position is a position in which the key blade is in the retracted position in the key case.

Le système anti-écartement du boitier de clé est configuré pour empêcher l'écartement du boitier de clé lorsque la tête de clé est en position de verrouillage/déverrouillage.The key case anti-spread system is configured to prevent the key case from spreading when the key head is in the lock/unlock position.

Par « tête de clé solidaire d'une lame de clé » ; on entend que la tête de clé est destinée à recevoir une lame de clé ou que la tête de clé et la lame de clé forment une seule pièce.By “key head attached to a key blade”; it is understood that the key head is intended to receive a key blade or that the key head and the key blade form a single piece.

Selon l'invention, le système anti-écartement comprend des moyens anti-écartement mobiles entre une position de blocage dans laquelle ils empêchent l'écartement du boitier de clé lorsque la tête de clé est en position de verrouillage/déverrouillage, et une position de déblocage dans laquelle ils autorisent l'écartement du boitier de clé lorsque la tête de clé est en position de repos. Ainsi, le boitier de clé est interchangeable lorsque la tête de clé est en position de repos. En outre, cette position de déblocage, permet de simplifier le montage de la clé et permet un montage automatisé.According to the invention, the anti-distancing system comprises anti-distancing means movable between a blocking position in which they prevent the distancing of the key case when the key head is in the locking/unlocking position, and a locking position. release in which they allow the separation of the key case when the key head is in the rest position. Thus, the key case is interchangeable when the key head is in the rest position. In addition, this unlocking position makes it possible to simplify assembly of the key and allows automated assembly.

La figure 1 représente une clé de l'art antérieur insérée dans un verrou, comme indiqué dans le préambule de la présente demande de brevet.The figure 1 represents a key of the prior art inserted in a lock, as indicated in the preamble of the present patent application.

Les figures 2 à 5 illustrent une clé 200 selon un exemple de réalisation de l'invention.The figures 2 to 5 illustrate a key 200 according to an embodiment of the invention.

La clé 200 comprend un boitier de clé 100 comprenant un premier capot de clé 102 et un deuxième capot de clé 104. Le premier capot de clé 102 et le deuxième capot de clé 104 sont configurés pour s'emboiter de sorte à former le boitier de clé 100, comme illustré à la figure 3.The key 200 includes a key shell 100 including a first key cover 102 and a second key cover 104. The first key cover 102 and the second key cover 104 are configured to fit together so as to form the key 100, as shown in picture 3 .

La clé 200 comprend en outre une clé mécanique 11 comprenant une tête de clé 12 solidaire d'une lame de clé 14 longitudinale. Plus précisément, la tête de clé 12 est disposée à une extrémité de la lame de clé 14. La clé mécanique 11 est destinée à être insérée dans le boitier 100, comme illustré à la figure 3.The key 200 further comprises a mechanical key 11 comprising a key head 12 integral with a longitudinal key blade 14. More specifically, the key head 12 is arranged at one end of the key blade 14. The mechanical key 11 is intended to be inserted into the box 100, as illustrated in picture 3 .

La tête de clé 12 est mobile en rotation selon un axe de rotation A (figure 2) entre une position de verrouillage/déverrouillage (figure 5) et une position de repos (figure 4). La position de verrouillage/déverrouillage est une position dans laquelle la lame de clé 14 est en position déployée à 180° en saillie du boitier de clé 100, tandis que la position de repos est une position dans laquelle la lame de clé 14 est en position rétractée dans le boitier de clé 100.The key head 12 is rotatable along an axis of rotation A ( figure 2 ) between a locking/unlocking position ( figure 5 ) and a rest position ( figure 4 ). The locking/unlocking position is a position in which the key blade 14 is in the 180° deployed position projecting from the key case 100, while the rest position is a position in which the key blade 14 is in position retracted in the key box 100.

Ainsi, le boitier de clé 100 permet d'autoriser la mobilité de la clé mécanique 11 entre la position de repos et la position de verrouillage/déverrouillage.Thus, the key box 100 makes it possible to authorize the mobility of the mechanical key 11 between the rest position and the locking/unlocking position.

En outre, selon un exemple de réalisation, la clé 200 peut comprendre un palier de retenue 16 de la tête de clé 12, formant un boitier intermédiaire pour la tête de clé. Dans l'exemple illustré, le palier de retenue 16 comprend un capot intermédiaire 18 et un support 20 pour la tête de clé 12, le capot intermédiaire 18 et le support 20 étant configurés pour coopérer par exemple par emboîtement, pour former le boitier intermédiaire pour la tête de clé. Le palier de retenue permet avantageusement de retenir la tête de clé 12 dans le boitier de clé 100 et d'autoriser sa rotation autour de l'axe de rotation A, c'est-à-dire selon un unique degré de liberté. Il permet également de former une butée angulaire de sorte à limiter la rotation de la tête de clé selon un angle de 180° par exemple.In addition, according to an exemplary embodiment, the key 200 may include a retaining bearing 16 of the key head 12, forming an intermediate box for the key head. In the example illustrated, the retaining bearing 16 comprises an intermediate cover 18 and a support 20 for the key head 12, the intermediate cover 18 and the support 20 being configured to cooperate, for example by interlocking, to form the intermediate box for the key head. The retaining bearing advantageously makes it possible to retain the key head 12 in the key case 100 and to allow its rotation around the axis of rotation A, that is to say according to a single degree of freedom. It also allows to form an angular stop so as to limit the rotation of the key head according to an angle of 180° for example.

Dans l'exemple représenté, l'axe de rotation A de la tête de clé 12 est disposé transversalement aux plans dans lesquels s'étendent les premier et deuxième capots.In the example shown, the axis of rotation A of the key head 12 is arranged transversely to the planes in which the first and second covers extend.

Par ailleurs, la clé 200 comprend un système anti-écartement 30 du boitier de clé 100, permettant d'empêcher l'écartement du boitier de clé 100. Dans l'exemple représenté, le système anti-écartement 30 permet également d'empêcher l'écartement du palier de retenue 16.Furthermore, the key 200 includes an anti-distancing system 30 of the key case 100, making it possible to prevent the distancing of the key case 100. In the example represented, the anti-distancing system 30 also makes it possible to prevent the spacing of the retaining bearing 16.

Dans une variante non représentée, la clé 200 ne comprend pas de palier de retenue. Dans cette variante, la clé est simplifiée du fait de la réduction du nombre de pièces. Les fonctionnalités techniques de maintien de la tête de clé 12, d'autorisation de sa rotation autour de l'axe de rotation et du butée angulaire sont alors réalisées directement par le boitier de clé 100, par exemple par la présence d'un élément de butée, se présentant par exemple sous la forme d'un capot, solidaire du premier capot de clé 102.In a variant not shown, the key 200 does not include a retaining bearing. In this variant, the key is simplified due to the reduction in the number of parts. The technical functionalities of maintaining the key head 12, of authorizing its rotation around the axis of rotation and of the angular stop are then carried out directly by the key box 100, for example by the presence of a abutment, for example in the form of a cover, secured to the first key cover 102.

A titre d'exemple, le système anti-écartement 30 comprend des moyens anti-écartement se présentant sous la forme d'une première patte 32 et d'une deuxième patte 34, la première patte 32 et la deuxième patte 34 sont des moyens anti-écartement. La première et la deuxième patte présentent une forme de L dans l'exemple représenté.By way of example, the anti-distancing system 30 comprises anti-distancing means in the form of a first tab 32 and a second tab 34, the first tab 32 and the second tab 34 are anti-distancing means - spacing. The first and the second tab have an L shape in the example shown.

Comme illustré plus précisément au regard des figures 6 à 8, dans un exemple de réalisation, la première patte 32 est solidaire du premier capot de clé 102 et la deuxième patte 34 est solidaire du deuxième capot de clé 104.As illustrated more precisely with regard to figures 6 to 8 , in an exemplary embodiment, the first lug 32 is secured to the first key cover 102 and the second lug 34 is secured to the second key cover 104.

Chaque patte présente un bec 36 configuré pour former une butée axiale afin d'empêcher l'ouverture du boitier de clé 100, comme il sera vu par le suite.Each leg has a beak 36 configured to form an axial stop in order to prevent the opening of the key box 100, as will be seen later.

Dans l'exemple illustré, chaque patte en forme de L présente une première branche solidaire du capot auquel elle est associée, et une deuxième branche perpendiculaire à la première branche, formant le bec 36.In the example shown, each L-shaped leg has a first leg secured to the cover with which it is associated, and a second leg perpendicular to the first leg, forming the spout 36.

En outre, dans le mode de réalisation dans lequel la clé 200 comprend un palier de retenue 16 formant un boitier intermédiaire pour la tête de clé 12, le palier de retenue 16 comprend des ouvertures 17 pour le passage des moyens anti-écartement, c'est-à-dire pour le passage des première 32 et deuxième 34 pattes dans l'exemple représenté aux figures 6 et 7 et plus précisément de la première branche de ces pattes. Plus particulièrement, dans l'exemple selon lequel le palier de retenue 16 comprend un capot intermédiaire 18 et un support 20 pour la tête de clé 12, le capot intermédiaire 18 comprend une ouverture 17 pour le passage de la première patte 32 et le support 20 comprend une ouverture 17 pour le passage de la deuxième patte 34.In addition, in the embodiment in which the key 200 comprises a retaining bearing 16 forming an intermediate box for the key head 12, the retaining bearing 16 comprises openings 17 for the passage of the anti-separation means, it that is to say for the passage of the first 32 and second 34 legs in the example shown in figures 6 and 7 and more precisely of the first branch of these legs. More particularly, in the example according to which the retaining bearing 16 comprises an intermediate cover 18 and a support 20 for the key head 12, the intermediate cover 18 comprises an opening 17 for the passage of the first leg 32 and the support 20 comprises an opening 17 for the passage of the second leg 34.

Les moyens anti-écartement, formés par la première patte 32 et la deuxième patte 34 dans l'exemple représenté, coopèrent avec la tête de clé 12 (figure 18) afin de maintenir le boitier de clé en position fermée.The anti-spreading means, formed by the first lug 32 and the second lug 34 in the example shown, cooperate with the key head 12 ( figure 18 ) to hold the key box in the closed position.

Plus précisément, comme illustré aux figures 9 à 11, la tête de clé 12 est formée d'une seule pièce et présente un logement 15 interne configuré pour accueillir les moyens anti-écartement. Ainsi, le système anti-écartement 30 comprend les moyens anti-écartement coopérant avec un logement.More specifically, as illustrated in figures 9 to 11 , the key head 12 is formed in one piece and has an internal housing 15 configured to accommodate the anti-separation means. Thus, the anti-distancing system 30 comprises anti-distancing means cooperating with a housing.

Ainsi, chaque patte est configurée pour effectuer un mouvement de déplacement relatif au logement avec lequel elle coopère selon une trajectoire T allant de la position de repos à la position de verrouillage/déverrouillage.The recesses in an arc of a circle 15 'allow the first 32 and second 34 legs to perform a stroke in the housing 15 of the key head, when the key head performs a rotation around the axis of rotation A ( picture 2 ) to move from the rest position to the locking/unlocking position. Thus, each lug is configured to perform a displacement movement relative to the housing with which it cooperates along a trajectory T going from the rest position to the locking/unlocking position.

Le bec 36 de chaque patte 32, 34 est disposé dans le prolongement de la trajectoire T allant de la position de repos à la position de verrouillage/déverrouillage.The beak 36 of each tab 32, 34 is arranged in the extension of the trajectory T going from the rest position to the locking/unlocking position.

L'évidement central 15" permet quant à lui de coopérer avec le bec 36 de chaque patte 32, 34 afin de former une butée axiale lorsque la tête de clé est en position de verrouillage/déverrouillage.The central recess 15" makes it possible to cooperate with the beak 36 of each lug 32, 34 in order to form an axial stop when the key head is in the locking/unlocking position.
