Description

La présente invention concerne le domaine des commutateurs électriques pour véhicules automobiles et en particulier des commutateurs d'ensemble de commandes sous-volant de véhicule automobile.The present invention relates to the field of electrical switches for motor vehicles and in particular motor vehicle steering wheel switch assembly switches.

De nombreuses structures de commutateurs électriques ont déjà été proposées. En particulier, on connaît des commutateurs électriques à chariot contacteur, monté mobile en translation pour établir, en fonction d'une commande d'un utilisateur, un contact électrique pour une ou plusieurs positions prédéfinies du trajet du chariot.Many electrical switch structures have already been proposed. In particular, there are known electrical switchgear switches, mounted movable in translation to establish, according to a command of a user, an electrical contact for one or more predefined positions of the carriage path.

Ces chariots contacteurs à courant faibles ou à courant fort, permettent d'établir le contact électrique, notamment par contact frottant, en regard de jeux de pistes électriques conductrices pour modifier des états de commutation.These low current or high current contact trolleys make it possible to establish the electrical contact, in particular by rubbing contact, with respect to sets of conductive electrical tracks for modifying switching states.

On désigne par courant faible, un courant visant à diffuser, recueillir ou échanger de l'information sous forme de signaux électriques. Les courants mis en causes sont parfois très faible (quelques mA à quelques µA).The term "weak current" refers to a current intended to diffuse, collect or exchange information in the form of electrical signals. The currents involved are sometimes very low (a few mA to a few μA).

A l'opposé, on désigne par courant fort, un courant apte à fournir de l'énergie électrique notamment destinée à des fonctions l'éclairage, de chauffage et de force motrice (lampes, résistances, moteurs...). Les courants mis en causes sont de l'ordre de quelques centaines de mA à plusieurs A.In contrast, the term "strong current" designates a current capable of supplying electrical energy, especially for lighting, heating and motive power functions (lamps, resistors, motors, etc.). The currents involved are of the order of a few hundred mA to several A.

On comprend que les performances exigées, notamment au niveau de la résistance mécanique et électrique, des chariots contacteurs à courant faible ou à courant fort, ne sont pas du tout les mêmes. Notamment, les contacteurs à courant forts doivent résister aux éventuels arcs électriques qui peuvent se former et qui peuvent abîmer le contact électrique.It is understood that the performance requirements, particularly in terms of mechanical and electrical resistance, low current contactor carriages or high current, are not at all the same. In particular, the strong current contactors must resist any arcing that may be formed and that can damage the electrical contact.

Cependant, dans le domaine automobile, certaines options du véhicule sont choisies par le client au dernier moment de l'assemblage du véhicule.However, in the automotive field, certain vehicle options are chosen by the customer at the last moment of vehicle assembly.

Il est alors nécessaire que les commutateurs d'ensemble de commande, et en particulier des commandes sous-volant, possèdent une très grande modularité et puissent ainsi être facilement intervertis en fonction des souhaits du client.It is then necessary that the control assembly switches, and in particular the sub-steering controls, have a very high degree of modularity and can thus be easily swapped according to the wishes of the customer.

Le document US 2007/0017788 décrit un dispositif selon le préambule de la revendication 1.The document US 2007/0017788 describes a device according to the preamble of claim 1.

Le but de la présente invention est donc de proposer un dispositif de commutation électrique de véhicule automobile ayant une plus grande modularité.The object of the present invention is therefore to provide a motor vehicle electrical switching device having a greater modularity.

A cet effet, l'invention a pour objet un chariot contacteur destiné à être monté mobile en translation dans un commutateur électrique d'un véhicule automobile, de préférence dans un ensemble de commandes sous-volant, pour établir, en fonction d'une commande d'un utilisateur, un contact électrique pour une ou plusieurs positions prédéfinies du trajet dudit chariot, comportant au moins un emplacement de contactage électrique, caractérisé en ce qu'il comporte un premier logement destiné à recevoir un élément contacteur à courant fort, et un deuxième logement destiné à recevoir un élément contacteur à courant faible, de sorte qu'un contact électrique soit susceptible d'être établi audit emplacement soit par la mise en place d'un élément contacteur à courant fort, soit par la mise en place d'un élément contacteur à courant faible dans le logement associé.For this purpose, the subject of the invention is a contactor carriage intended to be mounted mobile in translation in an electric switch of a motor vehicle, preferably in a set of sub-steering controls, for establishing, as a function of a control a user, an electrical contact for one or more predefined positions of the path of said carriage, comprising at least one electrical contact location, characterized in that it comprises a first housing for receiving a strong current contact element, and a second housing for receiving a low current contactor element, so that an electrical contact is likely to be established at said location either by the establishment of a strong current contactor element, or by the establishment of a low current contactor element in the associated housing.

L'invention a également pour objet un commutateur électrique d'un ensemble de commandes sous-volant de véhicule automobile, caractérisé en ce qu'il comporte un chariot contacteur tel que défini précédemment, et en ce qu'il comporte en outre au moins un élément contacteur à courant faible ou fort de manière à établir, en fonction d'une commande d'un utilisateur, un contact électrique à une ou plusieurs positions données sur le trajet dudit chariot.The invention also relates to an electric switch of a set of controls for a motor vehicle, characterized in that it comprises a contactor carriage as defined above, and in that it further comprises at least one contact element with low or high current so as to establish, according to a user command, an electrical contact at one or more given positions in the path of said carriage.

L'invention a encore pour objet une lame élastique de contactage à courant faible destinée à être mise en place dans un logement d'un chariot contacteur tel que défini précédemment, pour établir en fonction d'une commande d'un utilisateur, un contact électrique pour une ou plusieurs positions prédéfinies du trajet dudit chariot, comportant au moins un emplacement de contactage électrique, de sorte qu'un contact électrique soit susceptible d'être établi audit emplacement, caractérisé en ce qu'elle présente la forme d'une fourche ayant au moins deux branches aptes à établir deux contacts électriques simultanés et en ce que chaque branche possède une extrémité galbée.Another subject of the invention is a resilient low-current contact blade intended to be put into place in a housing of a contactor carriage as defined above, in order to establish, in function of a user's control, an electrical contact. for one or more predefined positions of the path of said carriage, comprising at least one electrical contact location, so that an electrical contact is likely to be established at said location, characterized in that it has the shape of a fork having at least two branches capable of establishing two simultaneous electrical contacts and in that each branch has a curved end.

Sur ces figures, les éléments identiques portent les mêmes numéros de référence.In these figures, the identical elements bear the same reference numbers.

Les figures 1 et 2 illustrent une partie d'un commutateur électrique 1 de véhicule automobile, tel que celui d'un ensemble de commandes sous-volant de véhicule automobile.The Figures 1 and 2 illustrate a portion of an electric switch 1 of a motor vehicle, such as that of a set of controls for a motor vehicle undercarriage.

Le commutateur 1 comporte un chariot contacteur 3 monté mobile en translation, par exemple à l'aide d'une glissière 5, sur un jeu de piste électrique conductrice 7 d'une carte à circuit imprimé 9 (voir figure 2).The switch 1 comprises a contactor carriage 3 mounted to be movable in translation, for example by means of a slideway 5, on a conductive electrical track set 7 of a printed circuit board 9 (see FIG. figure 2 ).

Le déplacement en translation du chariot contacteur 3 établit, en fonction d'une commande d'un utilisateur, un contact électrique pour une ou plusieurs positions prédéfinies du trajet du chariot 3.The translational movement of the contactor carriage 3 establishes, as a function of a user's command, an electrical contact for one or more predefined positions of the path of the carriage 3.

Au moins un élément contacteur à courant faible 11 ou fort 12 est mis en place dans un logement 15, 17, du chariot 3.At least one low-current contactor element 11 or strong element 12 is placed in a housing 15, 17 of the carriage 3.

On peut prévoir ainsi prévoir un commutateur 1 ayant un élément contacteur à courant fort 11 et un élément contacteur à courant faible 12 (figure 3).It is thus possible to provide a switch 1 having a high current contactor element 11 and a low current contactor element 12 ( figure 3 ).

Alternativement, on peut prévoir un commutateur 1 comportant un seul élément contacteur à courant faible 11, (figure 4) ou deux éléments à courants faibles 11 (figures 1 et 5).Alternatively, it is possible to provide a switch 1 comprising a single low-current contactor element 11, ( figure 4 ) or two weak current elements 11 ( figures 1 and 5 ).

Il est possible également de prévoir un commutateur 1 comportant un ou deux éléments contacteurs à courants forts 12 (figure 6).It is also possible to provide a switch 1 comprising one or two high current contactor elements 12 ( figure 6 ).

Le contact électrique modifiant les états de commutation, est établit à au moins un emplacement de contactage électrique 13, par contact frottant des éléments contacteurs 11 ou 12 en regard des pistes électriques 7.The electrical contact modifying the switching states is established at at least one electrical contact location 13, by rubbing contacting elements 11 or 12 opposite the electrical tracks 7.

On va maintenant décrire plus en détail le chariot contacteur 3 (figure 7), puis les éléments contacteurs à courant forts 12 (figure 9) et faibles 11 (figure 8).We will now describe in more detail the contactor trolley 3 ( figure 7 ), then the strong current contactors 12 ( figure 9 ) and weak 11 ( figure 8 ).

Le chariot contacteur 3 comporte un premier logement 15 destiné à recevoir un élément contacteur à courant fort 12, et un deuxième logement 17 destiné à recevoir un élément contacteur à courant faible 11, de sorte qu'un contact électrique soit susceptible d'être établi à l'emplacement 13 soit par la mise en place d'un élément contacteur à courant fort 12, soit par la mise en place d'un élément contacteur à courant faible 11 dans le logement associé 15, 17.The contactor carriage 3 comprises a first housing 15 intended to receive a high-current contactor element 12, and a second housing 17 intended to receive a low-current contactor element 11, so that an electrical contact is likely to be established at the location 13 is by the establishment of a high current contactor element 12, or by the establishment of a low current contactor element 11 in the associated housing 15, 17.

Ainsi, il est possible de disposer au choix soit un élément contacteur à courant faible 11, soit un élément contacteur à courant fort 12, pour l'établissement du contact électrique nécessaire à la mise en oeuvre de la commutation souhaitée à l'emplacement 13 du circuit électrique 7.Thus, it is possible to have either a low-current contactor element 11 or a high-current contactor element 12 for the establishment of the electrical contact necessary for the implementation of the desired switching at the location 13 of the electrical circuit 7.

En outre, on prévoit que le chariot 3 comporte un premier moyen d'encliquetage 19 (figure 7) destiné à coopérer avec un second moyen d'encliquetage complémentaire 21 porté par l'élément contacteur 11, 12, pour fixer de manière amovible l'élément contacteur 11, 12 avec le chariot 3.In addition, the carriage 3 is provided with a first latching means 19 ( figure 7 ) intended to cooperate with a second complementary latching means 21 carried by the contacting element 11, 12, for releasably fixing the contacting element 11, 12 with the carriage 3.

Ainsi, il est possible de modifier l'élément contacteur à courant fort 12 par un élément contacteur à courant faible 11 et vice-versa, alors même que l'assemblage a déjà été réalisé, ajoutant encore de la souplesse de réalisation au commutateur 1.Thus, it is possible to modify the high-current contactor element 12 by a low-current contactor element 11 and vice versa, even though the assembly has already been made, adding further flexibility to the switch 1.

Le premier moyen d'encliquetage 19 comporte avantageusement une protubérance ou un trou. Dans le mode de réalisation illustré par la figure 7, le premier moyen d'encliquetage 19 comporte une protubérance d'accrochage.The first latching means 19 advantageously comprises a protuberance or a hole. In the embodiment illustrated by the figure 7 , the first latching means 19 comprises a hooking protrusion.

Le premier logement 15 est défini par exemple, par au moins deux fentes 23 destinées à coopérer avec un élément contacteur à courant fort 12 correspondant.The first housing 15 is defined for example by at least two slots 23 for cooperating with a corresponding high current contactor element 12.

Avantageusement, l'élément contacteur à courant fort 12 comprend un pont contacteur 25 (figure 9).Advantageously, the high-current contactor element 12 comprises a contactor bridge 25 ( figure 9 ).

De préférence, le pont contacteur 25 comporte deux excroissances 26 aptes à établir deux contacts électriques simultanés aux emplacements 13 (figure 9).Preferably, the contactor bridge 25 comprises two protrusions 26 able to establish two simultaneous electrical contacts at the locations 13 ( figure 9 ).

Les deux contacts simultanés permettent de doubler la fonction de commutation, permettant ainsi d'améliorer la sécurité de commutation du commutateur 1.The two simultaneous contacts make it possible to double the switching function, thus making it possible to improve the switching security of the switch 1.

Le premier moyen d'encliquetage 21 de l'élément contacteur à courant fort 12 est avantageusement formé deux protubérances complémentaires portées par les ailes du pont 25, sur les faces extérieures.The first latching means 21 of the high-current contactor element 12 is advantageously formed by two complementary protuberances carried by the flanges of the bridge 25 on the outer faces.

On distingue sur la figure 3 que l'élément contacteur à courant fort 12 comporte un ressort 27 de rappel élastique du pont contacteur 25 disposé entre l'arche du pont 25 et le chariot 3.We distinguish on the figure 3 that the high-current contactor element 12 comprises a resilient return spring 27 of the contactor bridge 25 arranged between the arch of the bridge 25 and the carriage 3.

Ainsi, le pont 25 est constamment sollicité élastiquement à l'encontre des pistes du circuit 7.Thus, the bridge 25 is constantly biased elastically against the tracks of the circuit 7.

En revenant à la figure 7, on voit que le deuxième logement 17 est défini par au moins une fente 29 destinée à coopérer avec un élément contacteur à courant faible 11 correspondant, tel qu'une lame élastique de contactage, de sorte qu'un contact électrique soit susceptible d'être établi à l'emplacement 13.Returning to figure 7 it can be seen that the second housing 17 is defined by at least one slot 29 intended to cooperate with a corresponding low-current contactor element 11, such as an elastic contact blade, so that an electrical contact is likely to be established at location 13.

On prévoit avantageusement de disposer les fentes 23 du premier logement 15 parallèlement au plan défini par la fente 29 du deuxième logement 17, pour gagner en compacité.It is advantageously provided to arrange the slots 23 of the first housing 15 parallel to the plane defined by the slot 29 of the second housing 17, to gain compactness.

Plus précisément, et comme visible sur la figure 8, la lame élastique 11 présente avantageusement une première extrémité mobile en pivotement en forme d'une fourche destinée à établir un contact électrique.More precisely, and as visible on the figure 8 , the resilient blade 11 advantageously has a first end movable pivotally in the form of a fork for establishing an electrical contact.

La deuxième extrémité est destinée à être logée dans la fente 29 pour maintenir l'élément contacteur 11 dans le chariot 3.The second end is intended to be housed in the slot 29 to maintain the contactor element 11 in the carriage 3.

Les deux extrémités se rejoignent en formant un angle sensiblement supérieur à un angle droit, obtenu par exemple par pliage de la lame 11.The two ends meet at an angle substantially greater than a right angle, obtained for example by folding the blade 11.

Ainsi, l'extrémité destinée à établir un contact électrique est élastiquement sollicitée à l'encontre des pistes du circuit électrique.Thus, the end intended to establish an electrical contact is resiliently biased against the tracks of the electrical circuit.

Avantageusement, la première extrémité en forme de fourche possède au moins deux branches 31 aptes à établir deux contacts électriques simultanés.Advantageously, the first fork-shaped end has at least two branches 31 able to establish two simultaneous electrical contacts.

De même que dans le mode de réalisation décrit de l'élément contacteur à courant fort 12, les deux contacts électriques simultanés sont prévus dans l'élément contacteur à courant faible 11 par sécurité de commutation.As in the described embodiment of the high-current contactor element 12, the two simultaneous electrical contacts are provided in the low-current contactor element 11 for switching security.

De préférence, chaque branche 31 comporte au moins deux bras contacteurs 33 et chaque branche 31 ou bras contacteur 33 possède une extrémité galbée 35.Preferably, each branch 31 comprises at least two contactor arms 33 and each branch 31 or contactor arm 33 has a curved end 35.

L'espacement entre les deux branches 31 dépend de l'espacement entre les pistes électriques % du dispositif de commande.The spacing between the two branches 31 depends on the spacing between the electrical tracks% of the control device.

Ainsi, sur la figure 1, l'écartement entre les deux branches 31 n'est pas le même pour les deux éléments contacteurs à courants faibles 11. Il correspond à la disposition particulière des pistes conductrices 7 du circuit électrique inférieur.So, on the figure 1 , the spacing between the two branches 31 is not the same for the two weak current contactor elements 11. It corresponds to the particular arrangement of the conductive tracks 7 of the lower electrical circuit.

Alternativement, l'écartement est le même entre les deux branches 31 de deux lames élastiques 11 distinctes montées dans le commutateur 1, ce qui facilite la réalisation (figure 5).Alternatively, the spacing is the same between the two branches 31 of two separate resilient blades 11 mounted in the switch 1, which facilitates the realization ( figure 5 ).

Le premier moyen d'encliquetage 21 de l'élément contacteur 11 est avantageusement formé par au moins un, et de préférence deux crochets élastiques aptes à coopérer avec la protubérance d'accrochage 19 du chariot 3.The first latching means 21 of the contactor element 11 is advantageously formed by at least one, and preferably two elastic hooks adapted to cooperate with the hooking protrusion 19 of the carriage 3.

Par facilité de réalisation, les crochets sont découpés directement dans la lame élastique 11.For ease of manufacture, the hooks are cut directly into the elastic blade 11.

On prévoit de manière avantageuse, dans un chariot contacteur 3 comportant deux éléments contacteurs 11, 12, que les premiers logements 15 destinés aux éléments contacteurs à courant forts 12 sont situés sur les bords du chariot 3 relativement aux deuxièmes logements 17 destinés aux éléments contacteurs à courant faibles 11, situés au centre.Advantageously, in a contactor carriage 3 comprising two contacting elements 11, 12, the first housings 15 intended for the high-current contacting elements 12 are located on the edges of the carriage 3 relative to the second housings 17 intended for the contact elements to be connected. weak current 11, centrally located.

En effet, il est plus aisé d'agencer une lame élastique 11 logée dans le deuxième logement 17 et dont la fourche se prolonge jusqu'à l'emplacement 13, en passant au-dessus du premier logement 15 que l'inverse.Indeed, it is easier to arrange an elastic blade 11 housed in the second housing 17 and whose fork extends to the location 13, passing above the first housing 15 as the opposite.

Ainsi, on obtient un dispositif de commutation électrique 1 modulable comportant un chariot contacteur 3 comportant un premier logement 1 destiné à recevoir un élément contacteur à courant fort 12, et un deuxième logement 17 destiné à recevoir un élément contacteur à courant faible 11, de sorte qu'un contact électrique soit susceptible d'être établi à l'emplacement 13 soit par la mise en place d'un élément contacteur à courant fort 12, soit par la mise en place d'un élément contacteur à courant faible 11 dans le logement 15, 17 associé, permettant de fournir au choix un contact électrique à courant faible ou à courant fort, sans avoir à modifier complètement le commutateur, et donc la manette de commande sous-volant qui le contient.Thus, there is obtained a modular electrical switching device 1 comprising a contactor carriage 3 comprising a first housing 1 intended to receive a high-current contactor element 12, and a second housing 17 intended to receive a low-current contactor element 11, so that that an electrical contact is likely to be established in the location 13 is by the introduction of a high current contactor element 12, or by the establishment of a low current contactor element 11 in the housing 15, 17 associated, allowing to provide a choice of a low current or high current electrical contact, without having to completely change the switch, and therefore the sub-flying joystick that contains it.
