Description

DISPOSITIF D'ARRET D'OUVRANT NOTAMMENT DE VEHICULE AUTOMOBILE La présente invention concerne un dispositif d'arrêt d'ouvrant notamment de véhicule automobile. The present invention relates to an opening shut-off device in particular for a motor vehicle.

Les portes des véhicules automobiles sont généralement équipées de dispositifs à cames ou à crans permettant d'arrêter la porte dans une ou deux positions situées entre la position de fermeture et d'ouverture complète de la porte. Ces positions d'arrêt sont prédéfinies et donc immuables et 10 définissent une force de retenue de la porte que l'on peut franchir en exerçant un effort supérieur à cette force de retenue. Des dispositifs d'arrêt de ce type sont décrits notamment dans les documents JP 2004345498, EP 1728949, EP 1225291, FR2874051 et EP 1788176. 15 Certains ouvrants ou portes de véhicules automobiles sont équipés de dispositifs de commande électriques ou électrohydrauliques qui permettent d'arrêter l'ouvrant dans n'importe quelle position entre les positions de fermeture et d'ouverture complète. Cependant ces dispositifs sont coûteux et consomment 20 beaucoup d'énergie électrique. Le but de la présente invention est de proposer un dispositif d'arrêt d'ouvrant qui permette d'arrêter l'ouvrant dans n'importe quelle position qui ne nécessite pas d'unité de puissance et qui soit de ce fait peu coûteux et économe en énergie. 25 Ce but est atteint selon l'invention, grâce à un dispositif d'arrêt d'ouvrant notamment de véhicule automobile, caractérisé en ce qu'il comprend un vérin hydraulique dont une extrémité est reliée de façon articulée à l'ouvrant et l'autre extrémité est reliée de façon articulée à un point fixe, de telle sorte que le piston du vérin puisse se déplacer 30 dans le corps du vérin lors de l'ouverture et. de la fermeture de l'ouvrant, le vérin communiquant avec un circuit hydraulique comportant une vanne mobile entre une première position dans laquelle elle libère le passage du fluide hydraulique du circuit hydraulique et une seconde position dans laquelle elle ferme le passage 35 du fluide hydraulique. Motor vehicle doors are generally equipped with cam or notch devices to stop the door in one or two positions between the closed and fully open position of the door. These stop positions are predefined and thus immutable and define a door retaining force that can be overcome by exerting a force greater than this retaining force. Stop devices of this type are described in particular in documents JP 2004345498, EP 1728949, EP 1225291, FR2874051 and EP 1788176. Certain motor vehicle doors or gates are equipped with electrical or electrohydraulic control devices which make it possible to stop opening it in any position between the closed and fully open positions. However, these devices are expensive and consume a lot of electrical energy. The purpose of the present invention is to provide an opening shut-off device that allows the shutter to be stopped in any position that does not require a power unit and is therefore inexpensive and economical. in energy. This object is achieved according to the invention, by means of an opening shut-off device in particular of a motor vehicle, characterized in that it comprises a hydraulic cylinder, one end of which is connected in an articulated manner to the opening and the Another end is hingedly connected to a fixed point, so that the piston of the jack can move into the cylinder body during opening. closing the sash, the cylinder communicating with a hydraulic circuit having a valve movable between a first position in which it releases the passage of hydraulic fluid from the hydraulic circuit and a second position in which it closes the passage 35 of the hydraulic fluid.

Lorsque la vanne est dans la première position, le passage du fluide hydraulique est libre et le piston du vérin peut se déplacer dans le corps du vérin lorsqu'on ouvre ou ferme l'ouvrant. Lorsque la vanne est dans la seconde position, le passage du fluide hydraulique est fermé et le piston du vérin est bloqué : l'ouvrant est bloqué dans sa position et ce quelque soit cette position. Ainsi, si l'on veut bloquer l'ouvrant dans une position donnée quelconque il suffit de commander la vanne pour qu'elle ferme le passage du fluide hydraulique. When the valve is in the first position, the passage of hydraulic fluid is free and the piston of the cylinder can move in the cylinder body when opening or closing the opening. When the valve is in the second position, the passage of the hydraulic fluid is closed and the piston of the cylinder is blocked: the opening is locked in its position and whatever is this position. Thus, if one wants to block the opening in any given position it is sufficient to control the valve to close the passage of the hydraulic fluid.

De préférence, le vérin est un vérin à simple effet dont le corps renferme un ressort de compensation sollicitant le piston du vérin. De préférence également, la vanne est une vanne électrohydraulique. Dans un mode de réalisation préféré de l'invention, la vanne est commandée par deux contacteurs disposés en parallèle sur un circuit électrique de commande de la vanne. De préférence, l'un des contacteurs est disposé sur la face extérieure de ['ouvrant et l'autre contacteur est disposé sur la face intérieure de l'ouvrant. Preferably, the jack is a single-acting cylinder whose body contains a compensation spring biasing the cylinder piston. Also preferably, the valve is an electrohydraulic valve. In a preferred embodiment of the invention, the valve is controlled by two contactors arranged in parallel on an electrical control circuit of the valve. Preferably, one of the contactors is disposed on the outer face of the opening and the other contactor is disposed on the inner face of the opening.

Lorsque l'ouvrant est une porte de véhicule automobile, de préférence, l'un des contacteurs est situé près de la poignée extérieure et l'autre contacteur est situé près de la poignée intérieure. Ainsi, l'utilisateur peut facilement commander la vanne du dispositif selon l'invention, depuis l'extérieur ou l'intérieur du véhicule. When the opening is a motor vehicle door, preferably, one of the contactors is located near the outer handle and the other switch is located near the inner handle. Thus, the user can easily control the valve of the device according to the invention, from outside or inside the vehicle.

Selon une particularité avantageuse de l'invention, chacun des contacteurs est. mobile entre une position dans laquelle il commande la vanne vers la position ouverte dans laquelle elle libère le passage c'.0 fluide hydraulique et le déplacement de l'ouvrant et une position dans laquelle il commande la vanne vers la position fermée dans laquelle elle ferme le passage du fluide hydraulique et bloque le déplacement de l'ouvrant quelle que soit la position de celui-ci. De préférence, le circuit hydraulique comprend en outre un clapet double sens à limiteur mécanique, adapté pour permettre [e passage du fluide hydraulique en cas de défaillance du circuit électrique de commande de la vanne. D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après. According to an advantageous feature of the invention, each of the contactors is. movable between a position in which it controls the valve to the open position in which it releases the passage c'.0 hydraulic fluid and the movement of the opening and a position in which it controls the valve to the closed position in which it closes the passage of the hydraulic fluid and blocks the movement of the opening whatever the position thereof. Preferably, the hydraulic circuit further comprises a two-way valve with mechanical limiter, adapted to allow passage of the hydraulic fluid in the event of failure of the electrical control circuit of the valve. Other features and advantages of the invention will become apparent throughout the description below.

Aux dessins annexés, donnés à titre d'exemples, non limitatifs : - la figure 1 est une vue schématique de l'ensemble du dispositif d'arrêt d'ouvrant selon l'invention, - la figure 2 est une vue schématique en coupe horizontale d'une porte de véhicule automobile en position fermée et du vérin du dispositif d'arrêt, - la figure 3 est une vue analogue à la figure 2, montrant la porte en position partiellement ouverte. Comme montré sur les figures 1 à 3, le dispositif d'arrêt de porte 1 de véhicule automobile comprend un vérin hydraulique 2 dont une extrémité 2a est reliée de façon articulée à la porte 1 et l'autre extrémité 2b est reliée de façon articulée à un point fixe 3, de telle sorte que le piston 4 du vérin 2 puisse se déplacer dans le corps 5 du vérin lors de l'ouverture et de la fermeture de la porte 1. In the accompanying drawings, given by way of non-limiting example: FIG. 1 is a schematic view of the assembly of the shut-off device according to the invention; FIG. 2 is a schematic view in horizontal section; of a motor vehicle door in the closed position and the cylinder of the stop device, - Figure 3 is a view similar to Figure 2, showing the door in the partially open position. As shown in Figures 1 to 3, the motor vehicle door stop device 1 comprises a hydraulic cylinder 2, one end 2a is hingedly connected to the door 1 and the other end 2b is hingedly connected to a fixed point 3, so that the piston 4 of the cylinder 2 can move in the body 5 of the cylinder during the opening and closing of the door 1.

Le corps 5 du vérin 2 est relié à un circuit hydraulique 6 comportant une vanne 7 mobile entre une première position dans laquelle elle libère le passage du fluide hydraulique 8 et une seconde position dans laquelle elle ferme le passage du fluide hydraulique 8. Le circuit hydraulique 6 communique également avec un réservoir d'expansion 9. Dans l'exemple représenté sur la figure 1, le vérin 2 est un vérin à simple effet dont le corps 5 renferme un ressort de compensation 10 sollicitant le piston 4 du vérin. Par ailleurs, la vanne 7 est une vanne électro-hydraulique. The body 5 of the jack 2 is connected to a hydraulic circuit 6 comprising a valve 7 movable between a first position in which it releases the passage of the hydraulic fluid 8 and a second position in which it closes the passage of the hydraulic fluid 8. The hydraulic circuit 6 also communicates with an expansion tank 9. In the example shown in FIG. 1, the jack 2 is a single-acting cylinder whose body 5 contains a compensation spring 10 biasing the piston 4 of the jack. In addition, the valve 7 is an electro-hydraulic valve.

La vanne 7 est commandée par deux contacteurs 11, 12 disposés en parallèle sur un circuit électrique 13 de commande de la vanne 7. L'un des contacteurs 11 est disposé sur la face extérieure la de la porte 1 et l'autre contacteur 12 est disposé sur la face intérieure lb de la porte 1. The valve 7 is controlled by two contactors 11, 12 arranged in parallel on an electrical circuit 13 for controlling the valve 7. One of the contactors 11 is disposed on the outer face of the door 1 and the other contactor 12 is disposed on the inner face lb of the door 1.

Dans l'exemple de la figure 1, le contacteur 11 est situé près de la poignée extérieure 14 de la porte et l'autre contacteur 12 est situé près de la poignée intérieure intégrée dans l'accoudoir 15. Chacun des contacteurs 11, 12 est mobile entre une position dans laquelle il commande la vanne 7 vers la position ouverte dans laquelle elle libère le passage du fluide hydraulique 8 et le déplacement de la porte 1 et une position dans laquelle il commande la vanne 7 vers la position fermée dans laquelle elle ferme le passage du fluide hydraulique 8 et bloque le déplacement de la porte 1 quelle que soit la position de celle-ci. Dans l'exemple illustré par la figure 1, le circuit hydraulique 6 comprend en outre un clapet double sens 16 à limiteur mécanique, 5 adapté pour permettre le passage du fluide hydraulique 8 en cas de défaillance du circuit électrique de commande de la vanne 7. Le dispositif d'arrêt de porte que l'on vient de décrire fonctionne de la façon suivante. On supposera tout d'abord que la porte 1 est fermée, comme 10 montré sur la figure 2, et que le contacteur 12 situé à l'intérieur du véhicule est lui aussi fermé. Dans ce cas, la vanne 7 est elle-même fermée. Le fluide hydraulique 8 ne peut pas communiquer avec le réservoir d'expansion 9 et le piston 4 du vérin est. bloqué. 15 La porte 1 ne peut par conséquent pas s'ouvrir. Si l'occupant du véhicule ouvre le contacteur 12, la vanne 7 se déplace vers la position qui libère le passage du fluide hydraulique 8 et donc le déplacement du piston 4. Dans ce cas, on peut ouvrir la porte 1. 20 Lors de cette ouverture (voir figure 3) la porte 1 en pivotant sur son axe 17 tire la tige du piston 4 vers l'extérieur du vérin 2, comme indiqué par la flèche F. Si l'occupant du véhicule désire bloquer la porte 1 dans une position d'ouverture quelconque, il lui suffit de fermer le contacteur 12 25 pour commander la fermeture de la vanne 7 et la fermeture du passage du fluide hydraulique 8. Dans ce cas, le piston 4 du vérin est bloqué et la porte 1 est par conséquent bloquée. Les mêmes opérations que celles décrites ci-dessus peuvent être 30 commandées par le contacteur 11 situé à l'extérieur près de la poignée extérieure 14. En cas de défaillance du circuit électrique, la vanne 7 est bloquée dans la position de fermeture. Dans ce cas, la porte 1 est bloquée dans sa dernière position. 35 Elle peut néanmoins être débloquée grâce au clapet double sens 16 qui permet après avoir exercé un certain effort sur la porte pour In the example of Figure 1, the switch 11 is located near the outer handle 14 of the door and the other switch 12 is located near the inner handle integrated in the armrest 15. Each of the contactors 11, 12 is movable between a position in which it controls the valve 7 to the open position in which it releases the passage of the hydraulic fluid 8 and the movement of the door 1 and a position in which it controls the valve 7 to the closed position in which it closes the passage of the hydraulic fluid 8 and blocks the movement of the door 1 regardless of the position thereof. In the example illustrated in FIG. 1, the hydraulic circuit 6 further comprises a mechanical double-acting valve 16 adapted to allow the passage of the hydraulic fluid 8 in the event of failure of the electrical control circuit of the valve 7. The door stop device that has just been described operates as follows. It will be assumed first of all that the door 1 is closed, as shown in FIG. 2, and that the contactor 12 located inside the vehicle is also closed. In this case, the valve 7 is itself closed. The hydraulic fluid 8 can not communicate with the expansion tank 9 and the piston 4 of the cylinder is. blocked. Door 1 can not therefore open. If the occupant of the vehicle opens the switch 12, the valve 7 moves to the position which releases the passage of the hydraulic fluid 8 and thus the displacement of the piston 4. In this case, the door 1 can be opened. opening (see Figure 3) the door 1 by pivoting on its axis 17 pulls the piston rod 4 towards the outside of the cylinder 2, as indicated by the arrow F. If the occupant of the vehicle wishes to lock the door 1 in a position any opening, it is sufficient to close the switch 12 25 to control the closing of the valve 7 and closing the passage of the hydraulic fluid 8. In this case, the piston 4 of the cylinder is blocked and the door 1 is consequently blocked. The same operations as those described above can be controlled by the contactor 11 located outside near the outer handle 14. In the event of a failure of the electrical circuit, the valve 7 is locked in the closed position. In this case, the door 1 is locked in its last position. It can nevertheless be unlocked thanks to the double-handed valve 16 which, after exerting a certain amount of effort on the door,

faire céder le limiteur mécanique, d'ouvrir la communication du flu:Lde hydraulique 8 soit vers le vérin 2 soit vers le réservoir d'expansion 9. Dans ce cas, la porte peut se déplacer vers la position d'ouverture ou de fermeture. to give up the mechanical limiter, to open the communication of the fluid: hydraulic L 8 either to the cylinder 2 or to the expansion tank 9. In this case, the door can move to the open or closed position.

Le dispositif d'arrêt que l'on vient de décrire peut s'appliquer à tout type d'ouvrants pivotants ou coulissants. The stop device that has just been described can be applied to any type of pivoting or sliding opening.
