Description
La présente invention concerne, de façon générale, un dispositif de gestion d'alimentation électrique à double configuration, particulièrement destiné aux véhicules automobiles.The present invention relates, in general, to a dual configuration power supply management device, particularly for motor vehicles.
Plus précisément, l'invention concerne un dispositif de gestion d'alimentation électrique à double configuration pour véhicule automobile, comprenant un boîtier doté d'au moins trois bornes dont la première est une borne d'entrée principale reliée à une source électrique principale, dont la seconde est une borne de sortie reliée à des équipements électroniques à travers des éléments de protection tels que des fusibles, et dont la troisième est une borne d'entrée auxiliaire reliée à une source électrique auxiliaire.More specifically, the invention relates to a dual-configuration power supply management device for a motor vehicle, comprising a housing having at least three terminals, the first of which is a main input terminal connected to a main electrical source, whose the second is an output terminal connected to electronic equipment through protection elements such as fuses, and the third is an auxiliary input terminal connected to an auxiliary power source.
Des dispositifs de ce type sont connus dans l'art antérieur et utilisés pour gérer l'alimentation des véhicules automobiles pendant leur stockage sur parc et leur transport avant leur commercialisation.Devices of this type are known in the prior art and used to manage the supply of motor vehicles during park storage and transport before marketing.
En effet, les véhicules automobiles, après leur fabrication en usine de montage et avant leur commercialisation, sont d'abord stockés sur le parc de l'usine de montage pendant une durée variable qui dépend de l'adéquation entre la fabrication des véhicules et leur commande, puis sont transportés par différents moyens de transport jusqu'à leur lieu de commercialisation, et sont même éventuellement stockés sur des parcs intermédiaires, tels que des centres de distribution par exemple.Indeed, motor vehicles, after their manufacture in assembly plant and before their marketing, are first stored on the park of the assembly plant for a variable duration which depends on the adequacy between the manufacture of the vehicles and their order, then are transported by different means of transport to their place of sale, and are even possibly stored on intermediate fleets, such as distribution centers for example.
Or, les véhicules automobiles comportent des équipements électroniques de plus en plus nombreux, qui, dans le mode veille du véhicule c'est-à-dire avec le contact coupé, consomment quelques dizaines de milliampères.However, motor vehicles include more and more electronic equipment, which, in the standby mode of the vehicle that is to say with the ignition off, consume a few tens of milliamperes.
Aussi cette situation fait-elle naître le risque que la durée de vie de la batterie électrique équipant le véhicule puisse être affectée par un stockage prolongé du véhicule avant sa commercialisation.Also this situation gives rise to the risk that the life of the electric battery equipping the vehicle may be affected by prolonged storage of the vehicle before marketing.
Pour éviter la décharge de la batterie pendant les périodes de stockage et de transport du véhicule, il est donc nécessaire de déconnecter de la batterie les équipements électroniques consommateurs d'énergie.To prevent the battery from being discharged during periods of storage and transportation of the vehicle, it is therefore necessary to disconnect the energy-consuming electronic equipment from the battery.
Cependant, il est également nécessaire, à certains moments de ces périodes, de pouvoir déplacer le véhicule, par exemple pour l'amener sur un bateau ou un train, ce qui implique que le véhicule, lors de la remise du contact, doit redevenir opérationnel, notamment pour le démarrage du moteur et le fonctionnement des équipements de sécurité tels que l'éclairage, la signalisation, ou l'essuyage, et ceci sans exiger des manipulations complexes ou génératrices de pertes de temps.However, it is also necessary, at certain times during these periods, to be able to move the vehicle, for example to bring it on a boat or a train, which implies that the vehicle, when handing over the contact, must become operational again. , especially for starting the engine and the operation of safety equipment such as lighting, signaling, or wiping, and this without requiring complex handling or loss of time.
La solution couramment utilisée pour résoudre ce problème consiste à assurer l'alimentation permanente des équipements électroniques au moyen d'une source électrique auxiliaire dite "APC", et à travers une boîte de fusibles susceptible de prendre deux configurations différentes.The solution commonly used to solve this problem is to ensure the permanent supply of electronic equipment by means of an auxiliary power source called "APC", and through a fuse box that can take two different configurations.
Dans une première configuration, qui correspond au stockage du véhicule sur parc, un shunt est placé, à l'intérieur de la boîte de fusibles, dans une première position dans laquelle il assure la liaison électrique entre la source auxiliaire APC et les équipements électroniques, à travers les fusibles qui sont prévus pour protéger ces équipements et qui sont logés dans cette boîte.In a first configuration, which corresponds to the storage of the vehicle in the park, a shunt is placed, inside the fuse box, in a first position in which it provides the electrical connection between the auxiliary source APC and the electronic equipment, through the fuses that are provided to protect these equipment and that are housed in this box.
Dans une seconde configuration, qui correspond à l'utilisation du véhicule, le shunt est placé, à l'intérieur de la boîte de fusibles, dans une seconde position dans laquelle il assure la liaison électrique entre la source principale du véhicule, c'est-à-dire la batterie, et les équipements électroniques, à travers les mêmes fusibles de protection de ces équipements.In a second configuration, which corresponds to the use of the vehicle, the shunt is placed, inside the fuse box, in a second position in which it provides the electrical connection between the main source of the vehicle, it is ie the battery, and the electronic equipment, through the same fuses of protection of these equipments.
En réalité, la situation est un peu plus complexe, dans la mesure où l'ensemble du circuit d'alimentation qui doit être emprunté pour raccorder les équipements électroniques à la source auxiliaire APC n'est pas dimensionné pour assurer l'alimentation électrique des composants électroniques dans tous les états du véhicule, de sorte qu'il est nécessaire, dans la première configuration, d'utiliser non pas un shunt mais un fusible, dit "fusible parc", dimensionné pour fondre en cas d'utilisation simultanée d'un trop grand nombre d'équipements électroniques, et dans la seconde configuration, d'utiliser un shunt capable de résister à des valeurs de courant supérieures à celle pour laquelle le fusible doit fondre.In reality, the situation is a little more complex, as the entire supply circuit that must be used to connect equipment electronics to the APC auxiliary source is not sized to provide power to electronic components in all states of the vehicle, so it is necessary in the first configuration to use not a shunt but a fuse , called "park fuse", dimensioned to melt in case of simultaneous use of too many electronic equipment, and in the second configuration, to use a shunt capable of withstanding current values greater than that for which fuse must melt.
Le processus opératoire est alors le suivant.The operative process is then the following.
En fin de ligne de montage du véhicule, le shunt destiné à raccorder les équipements électroniques à la batterie est retiré pour éviter la décharge de cette dernière, et le fusible parc est mis en place pour permettre l'alimentation des équipements électroniques à partir de la source électrique auxiliaire utilisée sur le parc.At the end of the vehicle assembly line, the shunt for connecting the electronic equipment to the battery is removed to prevent the discharge of the latter, and the fuse park is set up to allow the supply of electronic equipment from the Auxiliary power source used on the park.
Lors de la livraison du véhicule dans le point de vente, et avant sa remise au client, le fusible parc est enlevé, et le shunt destiné à relier de façon permanente les équipements électroniques à la batterie est remis en place.When the vehicle is delivered to the point of sale, and before it is handed over to the customer, the park fuse is removed and the shunt for permanently connecting the electronic equipment to the battery is replaced.
Le problème est que, non seulement les opérations qui consistent à enlever le shunt, mettre le fusible, enlever le fusible et remettre le shunt sont relativement longues, mais ces opérations sont en outre malaisées dans la mesure où la boîte à fusibles destinée à recevoir sélectivement le shunt et le fusible est peu visible et d'un accès difficile.The problem is that not only the operations of removing the shunt, putting the fuse, removing the fuse and resetting the shunt are relatively long, but these operations are also difficult because the fuse box intended to selectively receive the shunt and the fuse is not very visible and difficult to access.
Le document de brevet GB 2 300 770 décrit un circuit d'alimentation électrique pour véhicule automobile comprenant une batterie et des charges électriques protégées par des fusibles et qui, en régime normal au moins, doivent être alimentées par la batterie.Patent document GB 2 300 770 describes a power supply circuit for a motor vehicle comprising a battery and electrical charges protected by fuses and which, under normal conditions at least, must be powered by the battery.
Ce document, qui évoque par ailleurs le risque de décharge de la batterie que fait naître la consommation de toutes les charges électriques pendant les périodes prolongées de non utilisation du véhicule, propose de diviser les charges électriques en deux classes, selon que ces charges sont, ou non, contrôlées par un interrupteur, c'est-à-dire selon qu'elles sont, ou non, susceptibles de consommer du courant en dehors des périodes où elles sont spécifiquement actionnées à la demande du conducteur du véhicule.This document, which also mentions the risk of battery discharge caused by the consumption of all electrical charges during extended periods of non-use of the vehicle, proposes dividing the electrical charges into two classes, depending on whether these charges are, or not, controlled by a switch, that is to say according to whether they are, or not, likely to consume power outside periods when they are specifically operated at the request of the driver of the vehicle.
Pour éviter le risque de décharge de la batterie, le circuit électrique proposé par le document GB 2 300 770 prévoit deux voies d'alimentation possibles de chaque charge électrique, l'une des voies reliant directement cette charge à la batterie, et l'autre voie reliant cette charge à la batterie par l'intermédiaire seulement de l'interrupteur du circuit d'allumage.To avoid the risk of battery discharge, the electrical circuit proposed by document GB 2 300 770 provides for two possible supply paths for each electrical load, one of the channels directly connecting this load to the battery, and the other way connecting this charge to the battery via only the switch of the ignition circuit.
Le fusible associé à chaque charge peut ainsi être relié à la batterie par la première voie ou par la deuxième voie, les fusibles des charges commandées par des interrupteurs indépendants, comme les phares ou l'avertisseur sonore, pouvant sans risque être reliés à la batterie par la première voie.The fuse associated with each load can thus be connected to the battery by the first channel or by the second channel, the fuses of the loads controlled by independent switches, such as the headlights or the buzzer, can safely be connected to the battery by the first way.
Dans ces conditions, il est possible de faire en sorte que les charges à consommation permanente, telles que l'horloge électrique, ne soient reliées à la batterie, par branchement de leur fusible sur la deuxième voie, que pendant le temps d'utilisation du véhicule si ce dernier n'est que rarement utilisé, mais soient reliées en permanence à la batterie, par branchement de leur fusible sur la première voie, si le véhicule est utilisé à une fréquence telle que le risque de décharge de la batterie n'existe pas.Under these conditions, it is possible to ensure that the permanent consumption charges, such as the electric clock, are connected to the battery, by connecting their fuse on the second channel, only during the time of use of the battery. vehicle if it is only rarely used, but are permanently connected to the battery, by connecting their fuse to the first channel, if the vehicle is used at such a frequency that the risk of battery discharge exists not.
Ainsi, non seulement le document GB 2 300 770 n'évoque pas du tout le problème que pose l'alimentation électrique du véhicule au moyen de deux sources électriques différentes, et notamment de la batterie et d'une source auxiliaire, mais il ne se préoccupe pas davantage, ni ne résout le problème que pose le branchement et le débranchement de fusibles plus ou moins fragiles à l'intérieur d'une boîte de connexion plus ou moins accessible.Thus, not only document GB 2 300 770 does not evoke at all the problem posed by the power supply of the vehicle by means of two different electrical sources, and in particular of the battery and an auxiliary source, but it does not worry or solve the problem of connecting and disconnecting more or less fragile fuses inside a junction box more or less accessible.
Le document de brevet DE 36 04 014 décrit quant à lui un interrupteur - inverseur utilisable dans un véhicule automobile, et dont l'embase est conçue pour pouvoir s'adapter à différents types d'organes mécaniques d'actionnement.The patent document DE 36 04 014 describes a switch-inverter for use in a motor vehicle, and whose base is designed to adapt to different types of mechanical actuators.
Le fonctionnement électrique du dispositif ainsi décrit est cependant totalement standard, le document DE 36 04 014 n'évoquant aucun problème spécifique que ce dispositif pourrait résoudre en matière d'alimentation électrique.The electrical operation of the device thus described is however completely standard, the document DE 36 04 014 evoking no specific problem that this device could solve in terms of power supply.
Dans ce contexte, la présente invention a pour but de proposer un dispositif permettant de résoudre le problème qui se pose dans le cas du recours à une alimentation électrique auxiliaire de véhicules en stationnement prolongé, et que représentent à la fois les difficultés de manipulation et la nécessité de gérer deux éléments de connexion électriques différents, à savoir un shunt et un fusible.In this context, the present invention aims to provide a device for solving the problem that arises in the case of the use of an auxiliary power supply of vehicles in extended parking, and that represent both the handling difficulties and the need to manage two different electrical connection elements, namely a shunt and a fuse.
A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend en outre un commutateur bistable comportant un corps, trois broches de connexion portés par le corps, et un contact électrique mobile également porté par le corps et reliant sélectivement la seconde broche à la première ou à la troisième, les trois broches de connexion étant sélectivement mises en contact électrique et en liaison mécanique avec les trois bornes respectives du boîtier, et en ce que le contact électrique mobile relie la seconde broche à la troisième à travers un fusible logé dans le corps du commutateur bistable.To this end, the device of the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that it further comprises a bistable switch comprising a body, three connection pins carried by the body, and a movable electrical contact also carried by the body and selectively connecting the second pin to the first or the third, the three connection pins being selectively brought into electrical contact and in mechanical connection with the three respective terminals of the housing, and in that the movable electrical contact connects the second pin to the third through a fuse housed in the body of the bistable switch.
De préférence, les broches de connexion, pour être mises en contact électrique et en liaison mécanique avec les trois bornes respectives du boîtier, sont conçues pour pouvoir être simultanément insérées dans les bornes respectives du boîtier.Preferably, the connection pins, to be brought into electrical contact and in mechanical connection with the respective three terminals of the housing, are designed to be simultaneously inserted into the respective terminals of the housing.
Si les éléments de protection des équipements électroniques sont logés dans le boîtier, ce dernier peut constituer une boîte à fusibles, et le commutateur peut alors être conçu pour s'adapter sur les boîtes de fusibles existantes sans modification de ces dernières.If the protective elements of the electronic equipment are housed in the housing, the latter can constitute a fuse box, and the switch can then be designed to fit on the existing fuse boxes without modification of the latter.
Par ailleurs les broches de connexion sont avantageusement parallèles entre elles, la seconde broche de connexion étant séparée des première et troisième broches par des première et seconde distances respectives, différentes l'une de l'autre, de manière à assurer un détrompage lors de la mise en place du commutateur bistable.Moreover, the connection pins are advantageously parallel to each other, the second connection pin being separated from the first and third pins by first and second respective distances, different from each other, so as to provide a foolproofing during the setting up the bistable switch.
Enfin, pour accroître encore la facilité de mise en oeuvre du dispositif, le commutateur bistable comporte de préférence un poussoir propre à commander le contact électrique mobile et disposé, sur le corps du commutateur, à l'opposé des broches de connexion.Finally, to further increase the ease of implementation of the device, the bistable switch preferably comprises a pusher adapted to control the movable electrical contact and disposed on the body of the switch, opposite the connecting pins.
