Abstract

The system includes a rigid substrate which contains the receiver electronics which is mounted in a housing. A printed circuit antenna (16) is etched on a flexible antenna extension (7a). Etching can be performed on both sides of the substrate. The antenna is coupled and connected to the main circuit. As the antenna circuit is flexible, it can be folded around the outer electronics housing.

Description

La présente invention est relative aux clés de véhicule automobile à télécommande radiofréquence, notamment pour le verrouillage/déverrouillage de portières, la désactivation de systèmes d'immobilisation, etc. The present invention relates to motor vehicle keys with radio frequency remote control, in particular for locking / unlocking doors, deactivating immobilization systems, etc.

Classiquement, la partie préhensible d'une telle clé est un boîtier dans lequel est reçu un circuit imprimé qui porte l'ensemble de l'électronique de la télécommande, et notamment l'antenne d'émission des signaux radiofréquences porteurs des messages codés. Conventionally, the graspable part of such a key is a box in which is received a printed circuit which carries all of the electronics of the remote control, and in particular the antenna for transmitting the radiofrequency signals carrying the coded messages.

Ce boîtier de préhension est par nature de petite taille. This gripping case is by nature small.

Or, ceci pose des problèmes pour l'implantation de l'antenne sur le circuit imprimé. Si l'on connaît en effet des technologies qui permettent de réaliser des antennes planaires (on pourra à cet égard se référer à
WO 94/13029), cette solution nécessite une surface de circuit assez importante car l'antenne, qui est par exemple réalisée sous forme d'une boucle rayonnante, doit être gravée dans une zone sensiblement éloignée de la zone d'implantation des autres composants et des pistes de connexion afin d'éviter les perturbations.However, this poses problems for the installation of the antenna on the printed circuit. If, in fact, we know of technologies which make it possible to produce planar antennas (we can in this regard refer to
WO 94/13029), this solution requires a fairly large circuit surface because the antenna, which is for example made in the form of a radiating loop, must be etched in an area substantially distant from the area of implantation of the other components and connection tracks to avoid disturbances.

Un but de l'invention est de résoudre ce problème. An object of the invention is to solve this problem.

A cet effet, l'invention propose une clé de véhicule automobile à télécommande radio fréquence comportant, dans un boîtier de préhension, un circuit imprimé qui comprend une antenne d'émission des signaux radiofréquences, caractérisée en ce que ledit circuit imprimé présente une partie souple rabattue sur laquelle est gravée ladite antenne. To this end, the invention provides a motor vehicle key with radio frequency remote control comprising, in a gripping box, a printed circuit which comprises an antenna for transmitting radio frequency signals, characterized in that said printed circuit has a flexible part folded down on which is engraved said antenna.

L'invention concerne également le circuit imprimé d'une telle clé. The invention also relates to the printed circuit of such a key.

D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit. Cette description est purement illustrative et non limitative. Elle doit être lue en regard des dessins annexés sur lesquels
- la figure 1 est une représentation en vue de dessus d'une clé à télécommande RF conforme à un mode de réalisation possible pour l'invention
- la figure 2 est une vue en coupe axiale de la clé de la figure 1 ;
- les figures 3a et 3b sont des représentations en vue de dessus et de dessous du circuit imprimé de la clé illustrée sur les figures 1 et 2
- la figure 4 est une vue en coupe selon la ligne
IV-IV de la figure 3b.Other characteristics and advantages of the invention will emerge from the description which follows. This description is purely illustrative and not limiting. It should be read in conjunction with the accompanying drawings on which
- Figure 1 is a top view representation of an RF remote control key according to a possible embodiment for the invention
- Figure 2 is an axial sectional view of the key of Figure 1;
- Figures 3a and 3b are representations from above and from below of the printed circuit of the key illustrated in Figures 1 and 2
- Figure 4 is a sectional view along the line
IV-IV of figure 3b.

La clé à télécommande illustrée sur les figures 1 à 3 comporte une partie métallique 1 et un boîtier de préhension 2 qui termine cette partie 1. The remote control key illustrated in FIGS. 1 to 3 comprises a metal part 1 and a grip box 2 which terminates this part 1.

Cette partie 1 forme la clé mécanique destinée à être introduite dans le barillet d'une serrure pour le verrouillage/déverrouillage manuel des portières, ou à servir lors de la mise du contact du véhicule. This part 1 forms the mechanical key intended to be introduced into the barrel of a lock for manual locking / unlocking of the doors, or to be used when the vehicle is switched on.

Le boîtier de préhension 2 reçoit l'ensemble de l'électronique de la télécommande radiofréquence. The gripping unit 2 receives all of the electronics of the radio frequency remote control.

Il est plus particulièrement constitué par deux demi-boîtiers 2a et 2b en matériau plastique refermés l'un sur l'autre. It is more particularly constituted by two half-housings 2a and 2b of plastic material closed one over the other.

Le demi-boîtier 2a est surmoulé sur la partie 1 formant clé mécanique et porte une carte 3 de circuit imprimé dont le contour correspond au contour intérieur dudit demi-boîtier 2a. Ce demi-boîtier 2a présente en outre une trappe 5 dans laquelle sont reçues des piles 4 pour l'alimentation dudit circuit imprimé 3. The half-box 2a is overmolded on the part 1 forming a mechanical key and carries a printed circuit board 3 whose contour corresponds to the internal contour of said half-box 2a. This half-casing 2a also has a hatch 5 in which batteries 4 are received for supplying said printed circuit 3.

Le circuit 3 est un circuit imprimé double face. Circuit 3 is a double-sided printed circuit.

Il est constitué par un substrat plat S rigide en un matériau diélectrique, dont chacune des faces porte un film de polyimide gravé 3a, 3b.It consists of a rigid flat substrate S made of a dielectric material, each of the faces of which carries an etched polyimide film 3a, 3b.

Celui - référencé par 3a - de ces deux films qui est dirigé vers le fond du demi-boîtier 2a présente, ainsi qu'on peut le voir sur la figure 3a, un disque cuivré 9 destiné à constituer l'une des bornes de contact des piles 4. I1 présente également un certain nombre de liaisons en cuivre 11 entre des plots 12 qui traversent le substrat S. The one - referenced by 3a - of these two films which is directed towards the bottom of the half-casing 2a has, as can be seen in FIG. 3a, a copper-plated disc 9 intended to constitute one of the contact terminals of the batteries 4. I1 also has a certain number of copper connections 11 between studs 12 which pass through the substrate S.

Le film de polyimide gravé 3b déposé sur l'autre face du substrat S est représenté sur la figure 3b. Il présente au moins deux parties l'une 6 qui est déposée sur le substrat S et qui adhère à celui-ci, l'autre 7a qui prolonge la partie 6 au delà du substrat S et qui constitue un volet souple rabattable. The etched polyimide film 3b deposited on the other face of the substrate S is shown in Figure 3b. It has at least two parts, one 6 which is deposited on the substrate S and which adheres thereto, the other 7a which extends the part 6 beyond the substrate S and which constitutes a flexible foldable flap.

Ces parties 6 et 7a du film 3b sont reliées par une portion 8 du film 3b, qui est de petite longueur et qui forme charnière. These parts 6 and 7a of the film 3b are connected by a portion 8 of the film 3b, which is of short length and which forms a hinge.

La partie souple 7a du film 3b porte la gravure 16 de l'antenne d'émission de la télécommande. Celle-ci peut être de toute forme. Sur la figure 3b, on a représenté le cas d'une antenne avec couplage vers une boucle fermée. The flexible part 7a of the film 3b carries the engraving 16 of the transmitting antenna of the remote control. This can be of any form. In Figure 3b, there is shown the case of an antenna with coupling to a closed loop.

D'autres types d'antennes seraient bien entendu envisageables : antenne à boucle ou à doublet par exemple.Other types of antennas would of course be conceivable: loop or doublet antenna for example.

Cette gravure 16 est reliée aux gravures de la partie 6 qui adhère au substrat rigide S. Celle-ci porte, outre les extrémités des plots traversants 12, un circuit intégré 13 de type ASIC, des plots 14 pour le montage de composants CMS, ainsi que des connexions 15 cuivrées entre ces différents éléments. This etching 16 is connected to the etchings of the part 6 which adheres to the rigid substrate S. This carries, in addition to the ends of the through studs 12, an integrated circuit 13 of the ASIC type, of the studs 14 for mounting SMD components, as well as copper-colored connections 15 between these different elements.

Cette partie 6 porte notamment des boutons poussoirs 17 (figure 1) disposés au droit de zones d'actionnement 10a, lOb, 10c du demi-boîtier 2b, qui sont destinées à être déformées élastiquement par pression par exemple du pouce de l'opérateur et qui sont respectivement dédiées aux différentes fonctions de la télécommande. This part 6 carries in particular push buttons 17 (FIG. 1) placed in line with actuation zones 10a, 10b, 10c of the half-housing 2b, which are intended to be elastically deformed by pressure, for example from the thumb of the operator and which are respectively dedicated to the different functions of the remote control.

Le demi-boîtier 2 présente au niveau de ces zones 10a, lOb, 10c des plots ou nervures intérieures 18 qui, lors des déformations desdites zones, viennent en contact avec les boutons poussoirs 17 pour déclencher la commande de l'émission des signaux RF codés. The half-housing 2 has, at these zones 10a, 10b, 10c, studs or internal ribs 18 which, when the zones are deformed, come into contact with the push buttons 17 to trigger the control of the transmission of the coded RF signals .

Par ailleurs, le demi-boîtier 2 porte au niveau des zones 10a, lob, 10c des inscriptions extérieures destinées à signaler à l'opérateur la fonction de chacune de ces zones : verrouillage des portières, déverrouillage, coupure des lumières intérieures d'un véhicule. Furthermore, the half-housing 2 carries at the areas 10a, lob, 10c external inscriptions intended to signal to the operator the function of each of these areas: locking the doors, unlocking, switching off the interior lights of a vehicle .

Le film 3b présente également une autre partie 7b qui prolonge la partie 6 au delà du substrat S et qui constitue également un volet souple. Cette partie 7b porte une diode électroluminescente 19, le demi-boîtier 2 présentant en regard de ladite diode 19 une lentille de dispersion 20. Ladite diode 19 peut par exemple être un composant à montage en surface (CMS).  The film 3b also has another part 7b which extends the part 6 beyond the substrate S and which also constitutes a flexible flap. This part 7b carries a light-emitting diode 19, the half-casing 2 having opposite said diode 19 a dispersion lens 20. Said diode 19 may for example be a surface mount component (CMS).

La partie souple 7a du film 3b présente, ainsi qu'on peut le voir sur les figures 3a et 3b, des évidements 21 destinés à être traversés par les boutons poussoirs 17. The flexible part 7a of the film 3b has, as can be seen in FIGS. 3a and 3b, recesses 21 intended to be crossed by the push buttons 17.

On notera également que la partie souple 7a et la gravure d'antenne 16 sont disposées de façon à être rabattues sur une zone de la partie 6 qui est éloignée du circuit intégré 13. Ainsi, la gravure d'antenne 10 ne perturbe pas le fonctionnement de ce circuit intégré 13. It will also be noted that the flexible part 7a and the antenna etching 16 are arranged so as to be folded over an area of the part 6 which is distant from the integrated circuit 13. Thus, the antenna etching 10 does not disturb the operation of this integrated circuit 13.

Le montage du boîtier 2 de télécommande s'effectue de la façon suivante. The mounting of the remote control unit 2 is carried out as follows.

Le circuit imprimé 3 étant préalablement réalisé, il est mis en place sur le demi-boîtier 2a, puis la partie 7a souple est rabattue, comme indiqué par la flèche 40 à la figure 4. The printed circuit 3 having been previously produced, it is put in place on the half-housing 2a, then the flexible part 7a is folded down, as indicated by the arrow 40 in FIG. 4.

Le demi-boîtier 2b est ensuite monté à force sur le demi-boîtier 2a, la diode électroluminescente 19 étant mise en place dans un logement de la lentille de dispersion 20.  The half-housing 2b is then forcibly mounted on the half-housing 2a, the light-emitting diode 19 being placed in a housing of the dispersion lens 20.

La trappe 5, avec son ressort, son joint d'étanchéité et les piles 4 sont ensuite mis en place sur le demi-boîtier 2a.  The hatch 5, with its spring, its seal and the batteries 4 are then placed on the half-housing 2a.
