Description

SYSTEME DE PARE-CHOC ET DE CAPTEURS DESTINES A UN SYSTEM DE PARCAGEBUMPER AND SENSOR SYSTEM FOR A PARKING SYSTEM
L ' invention se rapporte à un système formant pare- choc d' un véhicule automobile, comportant une pluralités de capteurs disposés notamment à la surface extérieure du pare-choc, ces capteurs étant destinés à faciliter le parcage .The invention relates to a bumper system of a motor vehicle, comprising a plurality of sensors arranged in particular on the outer surface of the bumper, these sensors being intended to facilitate the parking.
Généralement, on prévoit sur le véhicule qui peut être une automobile, une remorque ou autre, un certain nom- bre de capteurs, des conducteurs pour l ' alimentation de ceux-ci reliés à une source de courant électrique convenable et des conducteurs insérés entre les capteurs et un calculateur pour acheminer les informations détectées par les capteurs . De telles installations nécessitent souvent plusieurs capteurs et, par conséquent, un faisceau important de conducteurs, faisceau qu ' il n ' est pas touj ours simple de conformer compte tenu des emplacements des capteurs . En particulier, les capteurs du pare-choc se trouvant classiquement à la surface extérieure de celui ci se trouvent tous sensiblement dans un même plan vertical, et notamment sont sensiblement alignés suivant une droite, perpendiculaire à la direction longitudinale du câble plat qui les relient à un système central d' alimentation en courant et de traitement des informations reçues des capteurs . Dans un tel système le ou les systèmes centraux d' alimentation et de traitement se trouvent en arrière des capteurs, c' est à dire entre les deux plans extérieurs gauche et droite qui passent chacun par le capteur d' extrémité gauche, respectivement d' extrémité droite, de la pluralité de capteurs et qui sont perpendiculaire au plan vertical des capteurs . On souhaite suivant l' invention obtenir une liaison la plus simple et la moins encombrante possible par l ' intermédiaire de câbles plats .Generally, the vehicle, which may be an automobile, a trailer or the like, is provided with a certain number of sensors, conductors for powering them connected to a suitable electric power source, and conductors inserted between them. sensors and a computer to route the information detected by the sensors. Such installations often require several sensors and, consequently, a large bundle of conductors, a beam which it is not always easy to conform given the locations of the sensors. In particular, the sensors of the bumper conventionally located on the outer surface thereof are all substantially in the same vertical plane, and in particular are substantially aligned along a line perpendicular to the longitudinal direction of the flat cable which connect them to a central system for supplying power and processing information received from the sensors. In such a system, the central power supply and processing system is behind the sensors, that is to say between the two left and right outer planes which each pass through the left end or end sensor respectively. from the plurality of sensors and which are perpendicular to the vertical plane of the sensors. It is desired according to the invention to obtain a simplest connection and the least cumbersome possible via flat cables.
Un but de 1 ' invention est de faciliter la réalisation du faisceau . -An object of the invention is to facilitate the realization of the beam. -
Compte tenu de l ' importance du faisceau, on est obligé de prévoir un grand nombre de voies .Given the importance of the beam, it is necessary to provide a large number of channels.
Un autre but de 1 ' invention est de réduire ces voies .Another object of the invention is to reduce these channels.
Enfin, les liaisons électriques entre les conducteurs et les capteurs doivent être étanches . Un troisième but de l ' invention est de réaliser, d ' une manière simple, une telle liaison étanche .Finally, the electrical connections between the conductors and the sensors must be sealed. A third object of the invention is to provide, in a simple manner, such a sealed connection.
Suivant l ' invention, un système de pare-choc d' un véhicule automobile est tel que défini à la revendication 1. Des perfectionnements font l ' obj et des sous revendications .According to the invention, a bumper system of a motor vehicle is as defined in claim 1. Improvements are subject to claims.
Grâce à cette disposition, à partir d ' une simple nappe méplate comportant une série de pistes , on peut alimenter plusieurs capteurs , la conformation pour obtenir les différents éléments étant très simple .Thanks to this arrangement, from a simple flat sheet comprising a series of tracks, it is possible to feed several sensors, the conformation to obtain the different elements being very simple.
Afin de pouvoir réduire le nombre de voies , les pistes correspondant à l ' alimentation des capteurs sont shuntées de manière à limiter le nombre de voies reliées à la source d' alimentation.In order to reduce the number of channels, the tracks corresponding to the power of the sensors are shunted so as to limit the number of channels connected to the power source.
Afin que les voies puissent être groupées , les pistes correspondant à la transmission des informations re- levées par les capteurs sont reliées à des pistes shuntées par des dérivations avec des coupures .In order for the channels to be grouped, the tracks corresponding to the transmission of information the sensors are connected to shunted tracks by shunts with cuts.
Suivant une autre caractéristique, les pistes sont serties dans des prises femelles destinées à être engagées sur des languettes mâles , des capteurs s ' étendant dans une jupe, les prises étant montées dans un organe de guidage destiné à coopérer avec la surface interne de la jupe en ménageant à l ' arrière de celle-ci un espace libre destiné à recevoir une épaisseur de matière plastique surmoulée.According to another characteristic, the tracks are crimped into female sockets intended to be engaged on male tongues, sensors extending in a skirt, the sockets being mounted in a guiding member intended to cooperate with the internal surface of the skirt. by providing at the rear thereof a free space for receiving a molded plastics thickness.
Ainsi, les capteurs sont reliés de façon parfaitement étanche aux pistes de la nappe .Thus, the sensors are connected perfectly tight to the tracks of the sheet.
De préférence, l ' organe de guidage comporte des ailettes destinées à coopérer avec la surface interne de la jupe .Preferably, the guide member comprises fins intended to cooperate with the inner surface of the skirt.
Ainsi , on évite, lors de l ' inj ection de matière plastique, le fluage de celle-ci jusqu ' aux organes de contact électrique .Thus, during the injection of plastics material, the creep of the plastic material is avoided until it reaches the electrical contact members.
Afin que les pistes reliées aux capteurs ne puissent être arrachées , la matière plastique surmoulée englobe l ' extrémité des pistes adj acentes à la prise .In order that the tracks connected to the sensors can not be torn off, the overmolded plastic material includes the end of the tracks adjacent to the socket.
L ' invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d' exemple seulement et représentés au dessins annexés .The invention will now be described in more detail with reference to particular embodiments given by way of example only and represented in the accompanying drawings.
Figure 1 montre en perspective une nappe de conducteurs utilisée pour la réalisation de l ' installation, selon l ' invention .Figure 1 shows in perspective a layer of conductors used for the realization of the installation, according to the invention.
Figure 2 montre en perspective le découpage et le pliage de la nappe .Figure 2 shows in perspective the cutting and folding of the web.
Figure 3 montre en perspective le shuntage de la nappe afin de réduire le nombre de voies .Figure 3 shows in perspective the shunting of the sheet to reduce the number of channels.
Figure 4 et figure 5 montrent en coupe deux modes de liaison de la nappe aux capteurs .Figure 4 and Figure 5 show in section two modes of connection of the web to the sensors.
Dans le mode de réalisation représenté, on utilise une nappe 1 avec deux grands côtés la et Ib et présentant douze pistes 2.In the embodiment shown, a web 1 with two long sides 1a and 1b and having 12 tracks 2 is used.
La nappe formant câble plat est en partie découpée pour former des éléments 3 , 4 , 5 et 6 présentant, chacun, trois pistes 2. Ces éléments de trois pistes sont destinés à être reliés chacun à un capteur 7. Dans cette réalisation, il est prévu quatre capteurs 7 , 7a, 7b et 7c .The flat ribbon sheet is partly cut to form elements 3, 4, 5 and 6, each having three tracks 2. These elements of three tracks are intended to be each connected to a sensor 7. In this embodiment, it is provided four sensors 7, 7a, 7b and 7c.
Deux des trois pistes de chaque élément 3 , 4 , 5 et 6 sont destinées à l ' alimentation des capteurs , tandis que la troisième piste est destinée à véhiculer l ' information.Two of the three tracks of each element 3, 4, 5 and 6 are for the supply of the sensors, while the third track is for conveying the information.
Les capteurs 7 , 7a, 7b et 7c étant destinés à être fixés sur un pare-choc de véhicule pour constituer une partie d ' un ensemble d ' aide au parcage, ils sont soumis aux intempéries et on doit donc prévoir une liaison étanche . Les figures 4 et 5 montrent deux exemples de cette liaison .The sensors 7, 7a, 7b and 7c being intended to be fixed on a vehicle bumper to form a part of a parking aid assembly, they are subjected to the weather and must therefore provide a tight connection. Figures 4 and 5 show two examples of this connection.
Le capteur 7 est prolongé, à une extrémité, par une jupe 8 dans laquelle s ' étendent trois languettes de contact 9.The sensor 7 is extended at one end by a skirt 8 in which three tongues of contact 9.
Chaque capteur 7 a une extrémité distale 17 , à l ' opposé des pistes 2. Aux figures , les extrémités distales des capteurs sont disposées sensiblement dans un même plan vertical . Elles sont également sensiblement alignées suivant une droite . De préférence, les extrémités distales 17 affleurent à la surface extérieure du pare-choc , elles pourraient aussi se trouver à l ' intérieur ou à l ' extérieur de cette surface extérieure . Chaque ensemble 3 , 4 , 5 ou 6 reçoit une prise 10 présentant trois canaux 11 dans chacun desquels est logé et verrouillé un organe de contact électrique femelle 12 serti sur une piste 2.Each sensor 7 has a distal end 17, opposite the tracks 2. In the figures, the distal ends of the sensors are arranged substantially in the same vertical plane. They are also substantially aligned along a line. Preferably, the distal ends 17 are flush with the outer surface of the bumper, they could also be inside or outside this outer surface. Each set 3, 4, 5 or 6 receives a plug 10 having three channels 11 in each of which is housed and locked a female electrical contact member 12 crimped on a track 2.
La prise 10 est logée dans un organe de guidage 13 qui s ' insère avec, la prise dans la jupe 8 , Un espace libre 15 étant ménagé à l ' arrière de ladite jupe, cet espace libre étant rempli de matière plastique 16 par exemple par surmoulage .The plug 10 is housed in a guide member 13 which is inserted with the plug in the skirt 8, A free space 15 being formed at the rear of said skirt, this free space being filled with plastics material 16 for example by overmoulding.
Ainsi , la partie des pistes 2 adjacente à la prise 10 est noyée dans la matière plastique 16 ce qui assure une bonne tenue de 1 ' élément correspondant en même temps qu ' une parfaite isolation des organes de liaison électrique .Thus, the portion of the tracks 2 adjacent to the socket 10 is embedded in the plastics material 16 which ensures good holding of the corresponding element at the same time as perfect insulation of the electrical connection members.
La figure 5 montre une variante dans laquelle la prise 21 , qui est du même type que la prise 10 prévue dans la réalisation de la figure 4 , est logée dans un organe de guidage 18 dont une extrémité 18a comporte des ailettes 19 destinées à coopérer avec la surface interne de la jupe au voisinage du fond de cette dernière pour former des joints . L ' organe de guidage 18 , du côté 18b opposé à l ' extrémité 18a, est prolongé par une queue 20 percée d' un conduit 22 traversé par un élément 3 , 4 , 5 ou 6.FIG. 5 shows a variant in which the socket 21, which is of the same type as the socket 10 provided in the embodiment of FIG. 4, is housed in a guide member 18 whose end 18a comprises fins 19 intended to cooperate with the inner surface of the skirt in the vicinity of the bottom of the latter to form joints. The guide member 18, on the side 18b opposite the end 18a, is extended by a shank 20 pierced with a duct 22 through which a member 3, 4, 5 or 6 passes.
Dans la jupe 8 est ménagé un espace libre 23 entre l ' organe de guidage 20 et la surface interne de ladite jupe, espace dans lequel est inj ectée de la matière plastique 26.In the skirt 8 is provided a free space 23 between the guide member 20 and the inner surface of said skirt, space in which is injected plastic 26.
Afin d' assurer une bonne tenue des pistes de 1 ' élément correspondant au voisinage de l ' extrémité libre de la queue 20 , une pression est exercée, sur cette dernière, et le surmoulage comprend une partie débordant l ' extrémité libre de la queue 20 et dans laquelle sont noyées les pistes 2 correspondantes avec leur isolant .In order to ensure a good resistance of the tracks of the element corresponding to the vicinity of the free end of the tail 20, a pressure is exerted on the latter, and the overmoulding comprises a portion projecting beyond the free end of the tail. and in which are drowned the corresponding tracks 2 with their insulation.
Comme on le voit aux figures 2 et 3 , l ' utilisation d' une nappe de pistes se prête très aisément à un pliage permettant d' alimenter une série de capteurs disposés à des endroits différents .As can be seen in FIGS. 2 and 3, the use of a sheet of tracks is very easy to fold to feed a series of sensors arranged in different places.
L ' élément 3 est plié une première fois afin qu ' une partie 3a s ' étende perpendiculairement au bord la de la nappe 1 et une seconde fois pour qu ' une partie Ib soit dis- posée parallèlement audit bord la .The element 3 is folded a first time so that a portion 3a extends perpendicular to the edge 1a of the web 1 and a second time so that a portion Ib is disposed parallel to said edge 1a.
L ' élément 6 est plié une première fois pour présenter une partie 6a perpendiculaire au bord Ib de la nappe 1 et une seconde fois pour qu ' une partie 6b s ' étende parallèlement audit bord Ib .The element 6 is folded a first time to present a portion 6a perpendicular to the edge Ib of the web 1 and a second time so that a portion 6b extends parallel to said edge Ib.
L ' élément 5 est plié de la même façon que l ' élément 6 , la partie 5a étant perpendiculaire au bord Ib et la partie 5b parallèle à ce dit bord.The element 5 is folded in the same way as the element 6, the part 5a being perpendicular to the edge Ib and the part 5b parallel to this edge.
Enfin, l ' élément 4 devant s ' étendre entre les parties 3b et 5b est maintenu rectiligne .Finally, the element 4 to extend between the parts 3b and 5b is kept rectilinear.
On peut, bien entendu, prévoir que l ' élément 4 est plié symétriquement à 1 ' élément 5.It can, of course, be provided that the element 4 is folded symmetrically to the element 5.
Les pliages peuvent, suivant les emplacements de capteurs , être effectués d' une manière différente .The bends may, depending on the sensor locations, be made in a different manner.
Comme montré à la figure 2 , sur les six pistes centrales sont branchées des languettes 25 , 26 , 27 , 28 , 29 et 30 , tandis que sont montés des shunts reliant des pistes entre elles .As shown in Figure 2, the six central tracks are connected tongues 25, 26, 27, 28, 29 and 30, while are mounted shunts connecting tracks between them.
Le premier shunt 31 et le second shunt 32 sont destinés a l ' alimentation des capteurs et sont ainsi reliés aux languettes 27 et 28 , tandis que les autres pistes , des- tinées à être reliées à un calculateur et destinées à acheminer les signaux à partir des capteurs , sont reliées aux languettes 25 , 26 , 29 et 30.The first shunt 31 and the second shunt 32 are intended to supply the sensors and are thus connected to the tongues 27 and 28, while the other tracks, intended to be connected to a computer and intended to route the signals from the sensors, are connected to the tongues 25, 26, 29 and 30.
Afin de permettre de regrouper les languettes dans la partie centrale du câblage, la piste 2a prévue pour l ' acheminement des signaux à partir du capteur 7c est , par une dérivation 34 , reliée à une piste d' alimentation, celle-ci présentant une coupure 36 afin d' isoler de l ' alimentation la partie comprise entre la coupure et la lan- guette 30.In order to make it possible to group the tabs in the central portion of the wiring, the track 2a provided for the routing of the signals from the sensor 7c is, by a bypass 34, connected to a feed track, the latter having a cutoff 36 to isolate from the power supply the portion between the cut and the tongue 30.
De même, la piste 2b qui véhicule les signaux issus du capteur 7 est , par une dérivation 35 , reliée à une des pistes d ' alimentation par le shunt 31 avec une coupure 37 afin de l ' isoler de l ' alimentation .Similarly, the track 2b which carries the signals from the sensor 7 is, by a bypass 35, connected to a feeding tracks by the shunt 31 with a cut 37 to isolate it from the power supply.
Dans ce mode de réalisation, on a représenté des languettes et des shunts pour ramener le nombre de pistes initial de douze à six, mais on pourrait prévoir de relier la nappe 1 à une carte électronique, celle-ci pouvant accueillir des composants de gestion électroniques afin de réduire la connectique à un nombre limité de voies par mul- tiplexage des informations données par les capteurs .In this embodiment, there are shown tabs and shunts to reduce the initial number of tracks from twelve to six, but it could be expected to connect the sheet 1 to an electronic card, which can accommodate electronic management components to reduce the connectivity to a limited number of channels by multiplexing the information given by the sensors.
Bien entendu, l ' invention n' est pas limitée aux modes de réalisation qui viennent d' être décrits et représentés . On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l ' invention . Of course, the invention is not limited to the embodiments that have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
