Abstract

The key (10) has a lateral control button (12) placed between semi-shells (14, 16) of a single plastic shell. The shell forms a housing (18) for a pusher (20) controlled by the button. The pusher is formed by a rod that slides in the housing while co-operating with a helical spring (22). The spring returns the rod to a rest position in absence of action on the button, and is maintained in compression between the button and a surface (26) of the housing. The rod controls an on-off switch of a multimedia device in the key. A circular seal (32) is placed between the rod and walls of the housing.

Description

Clef électronique pour véhicule automobile munie d'un bouton latéral à rappel par tige La présente invention concerne une clef électronique pour véhicule automobile munie d'un bouton latéral à rappel par tige. The present invention relates to an electronic key for a motor vehicle provided with a side button with return by rod.

Il est connu d'intégrer dans une clef de véhicule automobile des dispositifs électroniques permettant de gérer des fonctions diverses telles que l'ouverture à distance des portes du véhicule ou la gestion d'un contenu multimédia stocké dans cette clef. Afin de commander ces fonctions, il est possible de munir une telle clef 10 électronique d'un bouton latéral permettant, selon l'exemple précédent, une navigation dans des contenus multimédia stockés. Un tel bouton latéral est actuellement obtenu par surmoulage de pièces plastiques. Par exemple, un bouton latéral est moulé sur une première coque - dénommée par la suite coque supérieure û venant en vis-à-vis d'une membrane 15 surmoulée sur une seconde coque û dénommée par la suite coque inférieure. Lorsque ce bouton latéral est comprimé par l'utilisateur, cette compression est transmise par la membrane surmoulée jusqu'à un poussoir venant en contact avec la membrane surmoulée. Ainsi, le bouton latéral permet de commander via ce poussoir un interrupteur commandant, selon l'exemple précédent, l'accès à un 20 contenu multimédia. La présente invention résulte de la constatation qu'un tel bouton latéral de clef électronique présente une robustesse insuffisante pour le domaine automobile. Notamment, les déformations subies par les matériaux comprimés à chaque sollicitation du bouton latéral entraînent des dysfonctionnements de la clef. 25 La présente invention vise à résoudre au moins un de ces inconvénients en proposant une clef électronique munie d'un bouton latéral plus robuste mais qui respecte par ailleurs les autres contraintes propres au domaine automobile, et notamment une certaine étanchéité. It is known to integrate in a motor vehicle key electronic devices for managing various functions such as remote opening of the vehicle doors or managing a multimedia content stored in this key. In order to control these functions, it is possible to provide such an electronic key with a side button allowing, according to the previous example, navigation in stored multimedia contents. Such a side button is currently obtained by overmolding plastic parts. For example, a side button is molded on a first shell - hereinafter referred to as the upper shell - facing a diaphragm 15 overmolded on a second shell - hereinafter referred to as the lower shell. When this side button is compressed by the user, this compression is transmitted by the overmolded membrane to a pusher coming into contact with the overmolded membrane. Thus, the side button allows to control via this pusher a commander switch, according to the previous example, access to a multimedia content. The present invention results from the observation that such an electronic key side button has insufficient robustness for the automotive field. In particular, the deformations suffered by the compressed materials at each biasing of the side button cause malfunctions of the key. The present invention aims to solve at least one of these disadvantages by proposing an electronic key provided with a more robust lateral button but which also respects the other constraints specific to the automotive field, and in particular a certain tightness.

C'est pourquoi, l'invention concerne une clef électronique munie d'un bouton latéral de commande agencé à une coque en plastique formant un logement pour un poussoir commandé par ce bouton latéral, caractérisé en ce que le poussoir est formé par une tige pouvant coulisser dans ce logement en coopérant avec des moyens de rappel ramenant la tige dans une position de repos en l'absence d'action sur le bouton latéral. Therefore, the invention relates to an electronic key provided with a lateral control button arranged to a plastic shell forming a housing for a pushbutton controlled by this side button, characterized in that the pusher is formed by a rod that can slide in this housing by cooperating with return means bringing the rod into a rest position in the absence of action on the side button.

Grâce à l'invention, le bouton latéral d'une clef électronique peut être commandé par le coulissement d'une tige, c'est-à-dire sans requérir la déformation d'une partie en plastique des coques. Ainsi, l'invention limite les problèmes d'usure des pièces et accroît la robustesse de la clef électronique. De plus, comme décrit ultérieurement, un joint peut être associé à la tige coulissante de telle sorte que l'étanchéité peut être assurée de façon satisfaisante au niveau d'un bouton latéral conforme à l'invention. Thanks to the invention, the lateral button of an electronic key can be controlled by the sliding of a rod, that is to say without requiring the deformation of a plastic part of the shells. Thus, the invention limits the problems of wear of the parts and increases the robustness of the electronic key. In addition, as described later, a seal may be associated with the sliding rod so that the seal can be satisfactorily provided at a side button according to the invention.

Dans une première réalisation, les moyens de rappel comprennent un ressort hélicoïdal maintenu en compression entre, d'une part, le bouton latéral et, d'autre part, une surface du logement de la tige située en vis-à-vis du bouton latéral. Selon une deuxième réalisation, le bouton latéral étant monté sur une première extrémité de la tige, une seconde extrémité de la tige présente un élément saillant venant en butée contre le logement de la tige lorsque le bouton latéral est en position de repos. Dans une troisième réalisation, un joint circulaire est situé entre la tige et les parois du logement en vis-à-vis de la tige. Selon une quatrième réalisation, le joint circulaire est logé dans une gorge de 25 la tige. Dans une cinquième réalisation, le bouton latéral est moulé sur la tige. Selon une autre réalisation, la tige est destinée à commander un interrupteur d'un dispositif multimédia intégré dans la clef électronique. In a first embodiment, the return means comprise a helical spring held in compression between, on the one hand, the side button and, on the other hand, a surface of the housing of the rod located opposite the side button. . In a second embodiment, the side button being mounted on a first end of the rod, a second end of the rod has a projecting member abuts against the housing of the rod when the side button is in the rest position. In a third embodiment, a circular seal is located between the rod and the walls of the housing vis-à-vis the rod. According to a fourth embodiment, the circular seal is housed in a groove of the rod. In a fifth embodiment, the side button is molded on the rod. In another embodiment, the rod is intended to control a switch of a multimedia device integrated in the electronic key.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description effectuée ci-dessous, à titre illustratif et non limitatif, en référence à l'unique figure ci-jointe sur laquelle est représentée une vue en coupe du bouton latéral d'une clef électronique conforme à l'invention. Other features and advantages of the invention will become apparent in the light of the description given below, by way of illustration and without limitation, with reference to the single attached figure on which is shown a sectional view of the side button an electronic key according to the invention.

Dans cette réalisation, ces moyens de rappel sont formés par un ressort hélicoïdal 22 entourant la tige 20 et venant en appui, d'une part, sur le bouton latéral 12 monté solidaire d'une première extrémité 24 de cette tige 20. 20 D'autre part, le ressort hélicoïdal 22 vient également en appui sur une surface 26 du logement 18 de la tige, cette surface 26 étant située en vis-à-vis du bouton latéral 12. Afin d'exercer une action de rappel, le ressort hélicoïdal 22 est maintenu comprimé dans le logement 18. Pour cela, une seconde extrémité 28 de la tige 25 présente un élément saillant 30 û tel qu'un clip ou un circlip - venant en butée contre les parois du logement 18 de la tige lorsque le bouton, en position de repos, maintient le ressort 22 hélicoïdal comprimé. Plus précisément, un circlip peut désigner un clip de forme circulaire. More specifically, this electronic key 10 is provided with a lateral control knob 12 located between a single shell formed of a single mold or, as in this embodiment, from two half-shells 14 and 16. In fact, it It is possible to form the shell of an electronic key by means of half-shells 14 and 16 arranged after introducing, in their respective internal volumes 10, electronic devices specific to the electronic key. Regardless of the embodiment of the hull, the latter has a housing 18 for a pusher 20 controlled by this side button 12. According to the invention, the pusher 20 is formed by a rod that can slide in its housing 18 by cooperating with return means 15 bringing said rod into a rest position in the absence of action on the side button 12. In this embodiment, these return means are formed by a helical spring 22 surrounding the rod 20 and bearing, on the one hand, on the side button 12 mounted integral with a first end 24 of this rod 20. On the other hand, the coil spring 22 also bears on a surface 26 of the housing 18 of the rod, this surface 26 in order to exert a return action, the helical spring 22 is held compressed in the housing 18. For this, a second end 28 of the rod 25 has an element protruding 30 - such as a clip or circlip - abutting against the walls of the housing 18 of the rod when the button, in the rest position, maintains the compressed coil spring 22. More specifically, a circlip may designate a circular clip.

Afin d'assurer l'étanchéité du bouton latéral 12, un joint circulaire 32 est situé entre la tige 20 et les parois du logement situées en vis-à-vis de la tige 20. Pour permettre le coulissement de la tige dans ce logement, la tige 20 présente une gorge 34 recevant le joint circulaire 32. To seal the side button 12, a circular seal 32 is located between the rod 20 and the housing walls located opposite the rod 20. To allow the sliding of the rod in this housing, the rod 20 has a groove 34 receiving the circular seal 32.

En fonction des différentes applications de l'invention, la tige 20 peut commander, par ses coulissements, l'interrupteur d'une application électronique accessible via la clef électronique, et notamment une application multimédia.
