Abstract
Description
La présente invention concerne une clef et un procédé de réalisation d'une telle clef. Plus particulièrement cette clef est adaptée pour commander l'ouverture et / ou la fermeture des portes d'un véhicule automobile.The present invention relates to a key and to a method for producing such a key. More particularly, this key is suitable for controlling the opening and / or closing of the doors of a motor vehicle.
Il est déjà connu des clefs, munies d'un dispositif de télécommande à infrarouge par exemple, adaptées pour télécommander l'ouverture des portes d'un véhicule automobile. Généralement de telles clefs sont réalisées par l'assemblage de deux demi-coques contenant un dispositif électronique de commande à distance et un panneton.Keys are already known, provided with an infrared remote control device for example, adapted for remotely controlling the opening of the doors of a motor vehicle. Generally, such keys are produced by assembling two half-shells containing an electronic remote control device and a bit.
Le dispositif de commande à distance comporte, entre autres, une diode électroluminescente adaptée pour servir de témoin de bon fonctionnement et une diode d'émission du signal infrarouge. L'étanchéité des demi-coques et de la diode émettrice est assurée par des joints d'étanchéité spécifiques, insérés aux endroits appropriés.The remote control device comprises, inter alia, a light-emitting diode adapted to serve as a functioning indicator and a diode for emitting the infrared signal. The half-shells and the emitting diode are sealed by specific seals, inserted in the appropriate places.
De manière connue, le dispositif de commande à distance est actionné, entre autres, par pression sur un organe déformable inséré dans une des demi-coques. Ainsi en pressant le boîtier au niveau de l'organe déformable, on provoque le fonctionnement du dispositif de télécommande et donc l'ouverture des portes du véhicule.In known manner, the remote control device is actuated, inter alia, by pressure on a deformable member inserted in one of the half-shells. By pressing the housing at the deformable member, it causes the operation of the remote control device and therefore the opening of the vehicle doors.
Un tel boîtier de clef est ainsi constitué de deux demi-coques, d'un dispositif de commande, de plusieurs joints d'étanchéité et d'un organe déformable. Le nombre relativement important de petites pièces à placer dans ce type de boîtier rend son procédé de fabrication long, délicat et onéreux.Such a key housing thus consists of two half-shells, a control device, several seals and a deformable member. The relatively large number of small parts to be placed in this type of case makes its manufacturing process long, delicate and expensive.
L'objet de la présente invention est de réduire au minimum le nombre de pièces à assembler pour réaliser une telle clef. On cherche aussi à diminuer les coûts et le temps de fabrication.The object of the present invention is to minimize the number of parts to be assembled to make such a key. We also seek to reduce costs and manufacturing time.
A cet effet la présente invention concerne une clef munie d'un dispositif de commande adapté pour commander à distance l'ouverture et / ou la fermeture des portes d'un véhicule automobile. Cette clef est constituée d'un panneton et de deux demi-coques adaptées pour loger entre elles le dispositif de commande et un joint d'étanchéité. Le dispositif de commande est du type comportant une pluralité de composants électroniques, une diode émettrice et un interrupteur actionné par un organe déformable solidaire d'au moins une des demi-coques. La clef, selon l'invention se caractérise en ce que l'organe déformable et le joint d'étanchéité sont réalisés de manière solidaire en un matériau unique et en ce que le dit joint réalise également l'étanchéité de la diode émettrice.To this end, the present invention relates to a key provided with a control device suitable for remotely controlling the opening and / or closing of the doors of a motor vehicle. This key consists of a bit and two half-shells adapted to accommodate between them the control device and a seal. The control device is of the type comprising a plurality of electronic components, a transmitting diode and a switch actuated by a deformable member secured to at least one of the half-shells. The key according to the invention is characterized in that the deformable member and the seal are made integrally from a single material and in that said seal also seals the emitting diode.
Grâce à cette disposition, tous les petits éléments nécessaires à la réalisation d'une clef sont solidaires les uns des autres, ce qui diminue le nombre de pièces à insérer dans le boîtier de clef. En outre avantageusement, le même matériau constitue l'organe déformable et le joint d'étanchéité.Thanks to this arrangement, all the small elements necessary for the production of a key are integral with each other, which reduces the number of parts to be inserted in the key housing. Furthermore advantageously, the same material constitutes the deformable member and the seal.
Avantageusement ce matériau est déposé par surmoulage sur une seule des deux demi-coques. Une telle dépose par surmoulage est facile à réaliser et peu onéreuse. Le nombre d'étapes nécessaires à la fabrication de cette clef est ainsi notablement réduit.Advantageously, this material is deposited by overmolding on only one of the two half-shells. Such removal by molding is easy to perform and inexpensive. The number of steps required to manufacture this key is thus significantly reduced.
La présente invention s'étend également à un procédé de fabrication d'une telle clef.The present invention also extends to a method of manufacturing such a key.
D'autres objets, caractéristiques et avantages, de la présente invention ressortiront d'ailleurs de la description qui suit à titre d'exemple non limitatif et en référence aux dessins annexés dans lesquels:
- la figure 1 est une vue en éclatée et en perspective montrant une clef selon l'invention,
- les figures 2a et 2b sont des vues en perspective de la demi-coque supérieure respectivement selon une vue de dessus, et une vue de dessous et,
- la figure 3 est une vue en coupe selon la ligne III - III de la figure 2b.
- FIG. 1 is an exploded and perspective view showing a key according to the invention,
- FIGS. 2a and 2b are perspective views of the upper half-shell respectively according to a top view, and a bottom view and,
- Figure 3 is a sectional view along line III - III of Figure 2b.
Selon la forme de réalisation représentée aux figures 1 à 3, la clef 10 selon l'invention comporte:
- deux demi-coques dites, inférieure 11a et, supérieure 11b,
- un dispositif électronique de
télécommande 12 de l'ouverture et / ou de la fermeture des portes d'un véhicule et, - un
panneton 13 de clef.
- two said half-shells, lower 11a and, upper 11b,
- an electronic
remote control device 12 for opening and / or closing the doors of a vehicle and, - a
key bit 13.
Le dispositif de télécommande 12 se compose essentiellement d'un certain nombre de composants électroniques 14 de types connus, d'une diode émettrice infrarouge 15, d'un interrupteur 16, de supports 17 et d'une diode électroluminescente 21.The
Comme on le voit mieux aux figures 2a et 2b le centre de la demi-coque supérieure 11b est obturé par un organe déformable 18. De manière connue lorsque l'utilisateur exerce une pression sur cet organe déformable, il actionne l'interrupteur 16 placé à l'aplomb de cet organe. De ce fait un code est émis par la diode émettrice 15 de telle sorte que la serrure d'automobile correspondant à cette clef soit actionnée. Le principe de fonctionnement de l'ouverture et de la fermeture des portes d'un véhicule est par ailleurs bien connu en soi et ne sera pas décrit ici.As best seen in Figures 2a and 2b the center of the upper half-
Le joint d'étanchéité 19 assurant l'étanchéité des demi-coques, l'une par rapport à l'autre, s'étend sur toute la périphérie de la coque supérieure 11b. Ce joint d'étanchéité assure également l'étanchéité de la diode 15. A cet effet le joint 19 présente une extension annulaire 19a, adaptée pour entourer la diode émettrice 15 et ainsi la rendre étanche. Ce joint 19 assure également l'étanchéité de la diode électroluminescente 21.The
En effet, cette diode 21 est adaptée pour rayonner vers l'extérieur de la demi-coque supérieure 11b, grâce à un voyant 22. Ce voyant est complètement entouré par le joint 19 qui présente à cet effet une partie annulaire 19b.In fact, this
Selon l'invention l'organe déformable 18 et le joint d'étanchéité 19, ne forme qu'une seule pièce et sont réalisés de manière monobloc par surmoulage.According to the invention, the
Avantageusement, ce surmoulage est réalisé dans une seule des demi-coques (11b dans l'exemple représenté).Advantageously, this overmolding is carried out in only one of the half-shells (11b in the example shown).
Le matériau servant à réaliser l'ensemble de l'organe déformable et du joint est par exemple un élastomère.The material used to produce the entire deformable member and the seal is for example an elastomer.
Lorsque le surmoulage de l'organe déformable et du joint est réalisé il suffit de placer le dispositif de commande à distance 12 dans les deux demi-coques, d'insérer le panneton 13, de refermer et de solidariser l'ensemble, pour réaliser la clef selon la présente invention.When the molding of the deformable member and of the seal is carried out, it suffices to place the
On notera que le nombre de pièces nécessaires à la réalisation de la clef selon l'invention est notablement réduit par rapport aux clefs existantes. En outre le procédé de fabrication est simple et comporte peu d'étapes.It will be noted that the number of parts necessary for the production of the key according to the invention is notably reduced compared to the existing keys. In addition, the manufacturing process is simple and has few steps.
On notera également que l'organe déformable 18 présente une large collerette annulaire 20 assurant l'étancnéité entre lui même et le boîtier. Ainsi le matériau surmoulé dans la demi-coque supérieure 11b réalise en même temps les fonctions suivantes:
- ◆ actionnement (18) de l'interrupteur 16,
- ◆ étanchéité (19) des demi-coques l'une par rapport à l'autre,
- ◆ étanchéité (19a) de la diode émettrice 15,
- ◆ étanchéité (19b) du voyant de la diode électroluminescente 21, et
- ◆ étanchéité (20) de l'organe déformable 18, par rapport à la demi-
coque 11b.
- ◆ actuation (18) of
switch 16, - ◆ sealing (19) of the half-shells relative to each other,
- ◆ sealing (19a) of the
emitting diode 15, - ◆ tightness (19b) of the
light emitting diode 21 indicator, and - ◆ sealing (20) of the
deformable member 18, relative to the half-shell 11b.
Bien entendu la présente invention n'est pas limitée au mode de réalisation précédemment décrit. Notamment la réalisation du surmoulage peut être effectuée dans l'une quelconque des deux demi-coques, voire sur les deux.Of course, the present invention is not limited to the embodiment described above. In particular, the molding can be carried out in any one of the two half-shells, or even on both.
