The electric vehicle has a battery terminal 5 so as to recharge its batteries (not shown). The battery terminal 5 is arranged on the front face of the vehicle 100.
[21] La station de recharge électrique 1 comprend un support 2 de borne de rechargement, sur lequel est disposé une borne de rechargement agencée pour être raccordée à la borne de batterie 5 du véhicule électrique 100. En référence à la figure 2, lorsque la borne de batterie 5 est couplée à la borne de rechargement 3, le plan de contact ou couplage est vertical. [21] The electric charging station 1 comprises a charging terminal support 2, on which is arranged a charging terminal arranged to be connected to the battery terminal 5 of the electric vehicle 100. With reference to Figure 2, when the battery terminal 5 is coupled to charging terminal 3, the contact plane or coupling is vertical.
[22] La station de recharge 1 comprend un boîtier 6 entourant ledit support. Le boîtier 6 présente une forme rectangulaire. Il réalise une fonction de protection de la borne de rechargement contre notamment les intempéries. En référence à la figure 3, le boîtier 6 présente une ouverture, dite ouverture frontale 7, réalisée sur la paroi frontale 7f du boîtier 6. L'ouverture frontale est agencée pour se situer en vis-à-vis avec la borne de rechargement. L'ouverture frontale 7 permet à la borne de batterie du véhicule électrique de venir se brancher directement sur la borne de rechargement 3 de la station. L'ouverture frontale 7 présente une forme rectangulaire comme la borne de rechargement 3. En-dehors de l'ouverture frontale 7, le boîtier 6 présente aucune ouverture. [22] The charging station 1 comprises a housing 6 surrounding said support. The box 6 has a rectangular shape. It performs a function of protecting the charging station against, in particular, bad weather. Referring to Figure 3, the housing 6 has an opening, called front opening 7, made on the front wall 7f of the housing 6. The front opening is arranged to be located vis-à-vis the charging terminal. The front opening 7 allows the battery terminal of the electric vehicle to be connected directly to the recharging terminal 3 of the station. The front opening 7 has a rectangular shape like the recharging terminal 3. Apart from the front opening 7, the case 6 has no opening.
[23] La station de recharge comprend des moyens de guidage en translation du boîtier. En référence aux figures 1 et 2, les moyens de guidage en translation sont des rails rectilignes disposés de part et d'autre du support 2. Ils permettent au boîtier 6 de se translater d'une position de repos (voir figure 1) à une position de recharge (voir figure 2). En référence à la figure 1, la paroi frontale 7f du boîtier 6 se situe à une distance de repos dr du plan de contact lorsque le boîtier est en position de repos. La distance de repos est environ égale à 50 centimètres, ou comprise entre 40 et 80 centimètres. [23] The charging station comprises means for guiding the housing in translation. Referring to Figures 1 and 2, the means for guiding in translation are rectilinear rails arranged on either side of the support 2. They allow the housing 6 to translate from a rest position (see Figure 1) to a charging position (see figure 2). Referring to Figure 1, the front wall 7f of the housing 6 is located at a rest distance dr from the contact plane when the housing is in the rest position. The resting distance is approximately equal to 50 centimeters, or between 40 and 80 centimeters.
[24] Lorsqu'une opération de rechargement d'un véhicule électrique est nécessaire, un véhicule électrique 100 se déplace et se présente devant une station de recharge électrique 1. Le véhicule avance dans une direction perpendiculaire au plan de contact et/ou une direction parallèle à la direction longitudinale du boîtier 6 jusqu'à prendre appui contre la paroi frontale 7f du boîtier 6. Selon un mode de réalisation illustré par la figure 3, le véhicule prend appui contre la paroi 7f par l'intermédiaire de surfaces ou zones d'appui 8 disposées sur la face extérieure de la paroi frontale 7f. Enfin le véhicule pousse le boîtier 6 jusqu'à ce que la borne de batterie 5 soit en couplage avec la borne de rechargement 3, comme représenté par la figure 2. En position de recharge la paroi frontale se situe à moins de 10 centimètres du plan de contact. [24] When a recharging operation of an electric vehicle is necessary, an electric vehicle 100 moves and presents itself in front of an electric recharging station 1. The vehicle advances in a direction perpendicular to the contact plane and/or a direction parallel to the longitudinal direction of the casing 6 until it bears against the front wall 7f of the casing 6. According to an embodiment illustrated by the FIG. 3, the vehicle bears against the wall 7f by means of support surfaces or zones 8 arranged on the outer face of the front wall 7f. Finally, the vehicle pushes the box 6 until the battery terminal 5 is coupled with the recharging terminal 3, as represented by FIG. 2. In the recharging position, the front wall is less than 10 centimeters from the plane of contact.
[25] La station de recharge électrique 1 comprend un moyen de rappel du boîtier 6 en position de repos lorsqu'un véhicule électrique se découple ou se débranche de la station de recharge. Le moyen de rappel est agencé de manière à exercer sur le boîtier un effort de rappel vers la position de repos, représenté par la flèche Ft. En référence aux figures 1 et 2, le moyen de rappel est représenté par un ressort 10. Le ressort 10 est relié à une première extrémité support 2, et à une seconde extrémité, opposée à la première, à la paroi arrière 13 du boîtier 6. Il peut aussi être constitué par un vérin [25] The electric charging station 1 comprises means for returning the housing 6 to the rest position when an electric vehicle uncouples or disconnects from the charging station. The return means is arranged so as to exert on the case a return force towards the rest position, represented by the arrow Ft. With reference to FIGS. 1 and 2, the return means is represented by a spring 10. The spring 10 is connected to a first support end 2, and to a second end, opposite the first, to the rear wall 13 of the casing 6. It can also be constituted by a cylinder
[26] De préférence, la station de recharge électrique comprend un volet 9 disposé à l'intérieur du boîtier 6. Le volet est mobile entre une position de protection (voir figure 1) dans laquelle le volet recouvre, ou est placé devant, la borne de rechargement 3 et une position de branchement (voir figure 2) dans laquelle le volet ne recouvre pas la borne de rechargement 3. [26] Preferably, the electric charging station comprises a flap 9 disposed inside the housing 6. The flap is movable between a protective position (see Figure 1) in which the flap covers, or is placed in front of, the recharging terminal 3 and a connection position (see figure 2) in which the flap does not cover the recharging terminal 3.
[27] En référence aux figures 1 et 2, le volet 9 comprend deux sections horizontales 91, 92 reliées entre elles par une liaison de pivotement. [27] Referring to Figures 1 and 2, the flap 9 comprises two horizontal sections 91, 92 interconnected by a pivot connection.
[28] De manière non représentée, la station de recharge électrique comprend des moyens de guidage et de liaison du volet relativement au support de manière à permettre le soulèvement et le basculement du volet pour passer de la position de protection à la position de branchement, et inversement. De préférence, les moyens de liaison comprennent une roue libre de pivotement 11 portée par un axe fixe par rapport au support. La roue libre de pivotement est agencée de manière que le volet bascule au contact de ladite roue et se déplace dans la direction de déplacement du boîtier. [28] In a manner not shown, the electric charging station comprises means for guiding and connecting the flap relative to the support so as to allow the lifting and tilting of the flap to pass from the protection position to the connection position, and vice versa. Preferably, the connecting means comprise a free pivoting wheel 11 carried by a fixed axle with respect to the support. The free pivoting wheel is arranged so that the shutter tilts in contact with said wheel and moves in the direction of movement of the housing.
[29] En outre, la station de recharge électrique comprend des moyens de liaison entre le volet 9 et le boîtier 6 de manière que le déplacement du boîtier 6 entraîne le déplacement du volet 9. En particulier, la section 92 du volet est reliée au boîtier 6. [29] In addition, the electric charging station comprises connection means between the flap 9 and the housing 6 so that the movement of the housing 6 causes the movement of the flap 9. In particular, the section 92 of the flap is connected to the box 6.
