Description

La présente invention est relative à un module de commande, en particulier pour véhicule automobile.The present invention relates to a control module, in particular for a motor vehicle.

Plus précisément, un tel module trouve une application avantageuse pour les commandes se trouvant au niveau de la console entre les deux sièges avant d'un véhicule automobile pour par exemple commander des fonctions de climatisation, d'un système audio, d'un système de téléphonie ou encore d'un système de navigation.More specifically, such a module finds an advantageous application for the controls located at the console between the two front seats of a motor vehicle for example to control air conditioning functions, an audio system, a control system. telephony or a navigation system.

L'invention peut aussi être appliquée dans une région du véhicule appelée le dôme qui se situe au niveau de l'emplacement habituel du rétroviseur intérieur pour par exemple commander des lumières intérieures, un verrouillage central, un toit ouvrant, les feux de détresse ou les lumières d'ambiance.The invention can also be applied in a region of the vehicle called the dome which is located at the usual location of the interior mirror for example to control interior lights, central locking, sunroof, hazard lights or mood lights.

Ce module peut également servir pour les commandes de lève-vitres, des commandes de positionnement des rétroviseurs extérieurs ou encore des commandes de déplacement de sièges motorisés.This module can also be used for window regulators, exterior mirrors positioning controls or motorized seat motion controls.

Dans le domaine automobile, les commandes de divers organes électriques sont réalisées classiquement par des commutateurs / interrupteurs. Toutefois, au vu du nombre croissant d'organes électriques à commander, des dispositifs de commande multifonctions sont de plus en plus utilisés du fait des avantages ergonomiques qui en résultent. En effet, à partir d'un seul bouton de commande, réalisé par exemple sous forme d'un joystick, associé à un écran d'affichage, on peut naviguer dans des menus déroulants pour commander par exemple la climatisation, le système audio ou encore le système de navigation.In the automotive field, the controls of various electrical components are conventionally performed by switches / switches. However, in view of the increasing number of electrical components to be controlled, multifunctional control devices are increasingly used because of ergonomic benefits that result. Indeed, from a single command button, made for example in the form of a joystick, associated with a display screen, you can navigate in drop-down menus to control for example the air conditioning, the audio system or even the navigation system.

Pour augmenter le confort ergonomique, l'utilisation d'une technologie à capteur tactile, seul ou en complément de tels boutons multifonctions, peut être considérée comme un développement intéressant.To increase the ergonomic comfort, the use of a touch sensor technology, alone or in addition to such multifunction buttons, can be considered as an interesting development.

En effet, les capteurs tactiles, en particulier pour le domaine automobile, ont fait des progrès importants. Une technologie utilisant des résistances sensibles à la pression (également connu sous le nom capteur FSR pour « Force Sensing Resistor ») devance de plus en plus d'autres technologies équivalentes, comme par exemple des technologies capacitives ou encore optiques grâce à sa facilité de mise en oeuvre et sa robustesse.Indeed, tactile sensors, especially for the automotive field, have made significant progress. A technology using pressure sensitive resistors (also known as FSR sensor for "Force Sensing Resistor") is ahead of more and more other equivalent technologies, such as capacitive or optical technologies thanks to its ease of use. implemented and its robustness.

De tels capteurs sont par exemple connus sous le nom tablette digitalisante (dénomination anglaise "Digitizer pad") et on cite comme art antérieur les documents suivants : US 4,810,992 , US 5,008,497 , FR 2683649 ou encore EP 0 541 102 .Such sensors are for example known as the digitizing tablet ("Digitizer pad") and the following documents are cited as prior art: US 4,810,992 , US5,008,497 , FR 2683649 or EP 0 541 102 .

Ces capteurs comprennent des circuits électriques souples formés par des couches semi-conductrices souples prises en sandwich entre par exemple une couche conductrice et une couche résistive. En exerçant une pression sur la couche FSR, sa résistance ohmique diminue permettant ainsi, par application d'une tension électrique adaptée, de mesurer la pression appliquée et / ou la localisation de l'endroit où la pression est exercée.These sensors comprise flexible electrical circuits formed by flexible semiconductor layers sandwiched between, for example, a conductive layer and a resistive layer. By exerting pressure on the FSR layer, its ohmic resistance decreases allowing, by applying a suitable voltage, to measure the pressure applied and / or the location of the place where the pressure is exerted.

Pour réaliser la connexion électrique du circuit électrique souple au réseau électrique du véhicule, on relie chaque piste de sortie du circuit souple à un connecteur électrique par l'intermédiaire d'un fil électrique ou d'une carte à circuit imprimé. Toutefois, une telle connexion nécessite la réalisation d'une première soudure pour relier la piste de sortie du circuit électrique souple au fil électrique associé ou à la piste d'entrée de la carte à circuit imprimé, puis une seconde soudure pour réaliser la connexion avec le connecteur électrique.To make the electrical connection of the flexible electrical circuit to the vehicle electrical network, each output track of the flexible circuit is connected to an electrical connector via an electrical wire or a printed circuit board. However, such a connection requires the realization of a first weld to connect the output track of the flexible electrical circuit to the associated electrical wire or to the input track of the printed circuit board, then a second solder to make the connection with the electrical connector.

La présente invention vise à proposer un module de commande du type précité avec une connectique simplifiée.The present invention aims to provide a control module of the aforementioned type with simplified connectivity.

A cet effet, l'invention a pour objet un module de commande comprenant au moins une surface de commande tactile réalisée sous forme d'un circuit électrique souple formant un capteur sensible à la pression exercée sur la surface tactile, ce circuit électrique souple possédant au moins une piste de sortie, caractérisé en ce qu'il comprend en outre au moins une broche de connexion associée à ladite piste de sortie dont une extrémité forme la partie mâle d'un connecteur électrique et dont l'autre extrémité est directement reliée mécaniquement et électriquement à ladite piste de sortie par sertissage.For this purpose, the subject of the invention is a control module comprising at least one tactile control surface made in the form of a flexible electrical circuit forming a sensor sensitive to the pressure exerted on the tactile surface, this flexible electric circuit having at least less an output track, characterized in that it further comprises at least one connecting pin associated with said output track, one end of which forms the male part of an electrical connector and the other end of which is directly mechanically connected and electrically to said exit track by crimping.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante, donnée à titre d'exemple, sans caractère limitatif, en regard du dessin annexé sur lequel est présenté une vue en coupe d'un module selon l'invention.Other features and advantages of the invention will become apparent from the following description, given by way of example, without limitation, with reference to the accompanying drawing which shows a sectional view of a module according to the invention.

La figure 1 montre un module de commande 1 selon l'invention.Figure 1 shows a control module 1 according to the invention.

Ce module de commande 1 comprend un boîtier 3 formé par un couvercle 5 et un fond 7 assemblés par exemple par des moyens d'encliquetage 9. Une ouverture 11 dans le couvercle 5 est remplie d'une matière élastique 13 telle que la silicone ou une mousse sur laquelle le doigt 15 d'un utilisateur appuie pour effectuer une commande. A l'intérieur du boîtier 3 est agencée une surface de commande tactile 17 réalisée sous forme d'un circuit électrique souple formant un capteur sensible à la pression exercée sur la surface tactile 17. Il s'agit par exemple d'un capteur de technologie FSR tel que décrit ci-dessus. Le circuit 17 se présente par exemple sous forme d'une feuille élastique en matière plastique à l'intérieur de laquelle évoluent des pistes croisées d'une encre conductrice pour former une matrice permettant de détecter au moins les coordonnées x de la position de l'appui et la pression exercée (direction z) sur le capteur, et dans une version plus évoluée, les coordonnées en x, y et z.This control module 1 comprises a housing 3 formed by a cover 5 and a bottom 7 assembled for example by latching means 9. An opening 11 in the cover 5 is filled with an elastic material 13 such as silicone or a foam on which the finger 15 of a user presses to make a command. Inside the housing 3 is arranged a tactile control surface 17 made in the form of a flexible electrical circuit forming a pressure sensitive sensor exerted on the touch surface 17. This is for example a technology sensor FSR as described above. The circuit 17 is for example in the form of an elastic sheet of plastic material within which cross tracks of a conductive ink evolve to form a matrix for detecting at least the x-coordinates of the position of the support and the pressure exerted (direction z) on the sensor, and in a more evolved version, the coordinates in x, y and z.

Ce capteur 17 est fixé sur une paroi 19 du boîtier 3 formant un plateau-support, de préférence à l'aide d'une colle.This sensor 17 is fixed on a wall 19 of the housing 3 forming a support plate, preferably with the aid of an adhesive.

Le circuit électrique souple 17 possède au moins une piste de sortie 20, mais en général trois pistes de sortie parallèles correspondant pour la première à une piste de sortie pour les coordonnées en x, pour la seconde à une piste d'alimentation en tension, et puis à une piste de raccordement à la masse. On comprend donc que par piste de sortie, on entend toute piste de raccordement électrique du circuit électrique souple.The flexible electrical circuit 17 has at least one output track 20, but generally three parallel output tracks corresponding for the first to an output track for the x coordinates, for the second to a voltage supply track, and then to a ground connection track. It is therefore understood that output track means any electrical connection track of the flexible electrical circuit.

Au niveau des pistes de sortie, le circuit 17 est recourbé pour passer en dessous du plateau support 19 pour se terminer dans une partie 21 du boîtier 3 formant connecteur électrique intégré qui sera maintenant décrit en détail.At the output tracks, the circuit 17 is bent to pass below the support plate 19 to end in a portion 21 of the housing 3 forming integrated electrical connector which will now be described in detail.

Pour connecter le circuit 17 par exemple à une unité de traitement des signaux, il est prévu dans le boîtier une broche 23 de connexion par piste de sortie 20. Une première extrémité 25 de la broche de connexion forme la partie mâle d'un connecteur électrique et est destinée à coopérer avec une partie femelle non représentée.To connect the circuit 17, for example, to a signal processing unit, there is provided in the housing an output track connection pin 23. A first end 25 of the connection pin forms the male part of an electrical connector and is intended to cooperate with a not shown female part.

L'extrémité opposée 27 de la broche de connexion est directement reliée mécaniquement et électriquement à la piste de sortie associée par sertissage.The opposite end 27 of the connection pin is directly mechanically and electrically connected to the associated crimped output track.

A cet effet, l'extrémité 27 de la broche de connexion 23 en regard de ladite piste de sortie comprend au moins une, de préférence deux pointes de connexion 29 qui transpercent ladite piste de sortie 20 pour établir un contact électrique et qui sont recourbées par sertissage en direction de la broche pour assurer de plus un maintien mécanique entre le circuit souple 17 et la broche de connexion 23.For this purpose, the end 27 of the connection pin 23 opposite said output track comprises at least one, preferably two connection points 29 which piercing said output track 20 to establish an electrical contact and which are bent by crimping in the direction of the pin to further ensure a mechanical hold between the flexible circuit 17 and the connection pin 23.

A cet effet, l'extrémité 27 de la broche de connexion 23 comprend une partie aplatie 31 et les pointes de connexion 29 sont formées par exemple par une portion estampée de la partie aplatie 31.For this purpose, the end 27 of the connecting pin 23 comprises a flattened portion 31 and the connecting tips 29 are formed for example by a stamped portion of the flattened portion 31.

Ainsi, en transperçant la piste de sortie, on réalise une connexion électrique fiable entre le circuit électrique souple 17 et la broche de connexion 23, et en sertissant par pliage les pointes de connexion 29, on assure de plus un excellent maintien mécanique.Thus, by piercing the output track, a reliable electrical connection is made between the flexible electrical circuit 17 and the connection pin 23, and crimping the connection tips 29 by folding, further ensures excellent mechanical retention.

La broche de connexion 23 est fixée directement dans la partie 21 du boîtier 3 formant connecteur électrique.The connection pin 23 is fixed directly in the portion 21 of the housing 3 forming an electrical connector.

Plus en détail, le boîtier 3 comprend une paroi 33 qui forme un fond de connecteur et qui est traversée par la ou lesdites broches de connexion 23. De préférence et dans un souci de réduire l'encombrement du module de commande, cette paroi 33 est située en dessous du plateau support 19 portant le circuit électrique 17 et perpendiculaire à celui-ci.In more detail, the housing 3 comprises a wall 33 which forms a connector bottom and which is crossed by the connection pin or pins 23. Preferably and for the sake of reducing the size of the control module, this wall 33 is located below the support plate 19 carrying the electrical circuit 17 and perpendicular thereto.

Avantageusement la paroi 33 de boîtier formant fond de connecteur est réalisée d'une seule pièce avec le plateau-support 19 permettant de réduire ainsi le nombre de pièces du module et son coût de revient.Advantageously, the wall 33 of the housing forming a connector bottom is made in one piece with the support plate 19 thus reducing the number of parts of the module and its cost.

Pour le maintien mécanique des broches de connexion 23, la paroi 33 comporte pour chaque broche une ouverture traversante 35 dans laquelle la broche est insérée à force.For the mechanical holding of the connection pins 23, the wall 33 comprises for each pin a through opening 35 in which the pin is inserted by force.

Pour prévenir tout déplacement de la broche 23 lors de la connexion avec une partie femelle, la broche de connexion comprend des crochets anti-retour latéraux 37 coopérant avec ladite paroi 33 de boitier pour maintenir la broche en position.To prevent any movement of the pin 23 when connected with a female part, the connection pin comprises lateral non-return hooks 37 cooperating with said case wall 33 to hold the pin in position.

Pour assurer un positionnement précis lors de l'insertion de la broche 23 dans l'ouverture 35, la broche de connexion 23 comprend une collerette 39 formant une butée.To ensure accurate positioning when inserting the pin 23 into the opening 35, the connecting pin 23 comprises a flange 39 forming a stop.

Pour protéger la connexion des pistes de sorties 20 aux broches de connexion associées 23, il s'est avérée avantageux d'entourer cette partie de connexion d'une colle de fusion à chaud 41.To protect the connection of the output tracks 20 to the associated connection pins 23, it has proved advantageous to surround this connection part with a hot-melt adhesive 41.

On comprend donc que la module de commande selon l'invention se distingue par un nombre réduit de pièces et un faible encombrement, ce qui permet un coût de revient compétitif.It is therefore clear that the control module according to the invention is distinguished by a small number of parts and a small footprint, which allows a competitive cost.
