Description
L'invention concerne un véhicule automobile comprenant un ouvrant dont lesThe invention relates to a motor vehicle comprising an opening
mouvements de fermeture et d'ouverture sont motorisés au moyen d'un actionneur. closing and opening movements are motorized by means of an actuator.
Plus particulièrement, l'invention concerne un véhicule du type cabriolet comprenant un ouvrant tel qu'un capot de coffre pouvant s'ouvrir de l'avant vers l'arrière et de l'arrière vers l'avant grâce à un système de charnières libérables et dont les mouvements de fermeture et d'ouverture sont motorisés au moyen d'un actionneur io de sorte à automatiser lesdits mouvements. More particularly, the invention relates to a vehicle of the cabriolet type comprising an opening such as a boot lid that can open from the front to the rear and from the rear to the front thanks to a system of releasable hinges and whose closing and opening movements are motorized by means of an actuator 10 so as to automate said movements.
On connaît des véhicules équipés d'un ouvrant dont les mouvements d'ouverture et de fermeture sont motorisés au moyen d'un actionneur. Vehicles are known equipped with an opening whose opening and closing movements are motorized by means of an actuator.
Cependant, un des problèmes de ce type d'ouvrant est de sécuriser leur ouverture et leur fermeture, en particulier lors d'un mouvement automatique. En effet, un objet ou une partie du corps tel qu'une main est susceptible de se faire pincer entre l'ouvrant et une partie fixe du véhicule. Dans le cas d'un ouvrant tel qu'un un capot de coffre, ces pincements sont particulièrement dangereux car les actionneurs hydrauliques ou électriques utilisés sont particulièrement puissants étant donné le poids du capot. However, one of the problems of this type of opening is to secure their opening and closing, especially during an automatic movement. Indeed, an object or a body part such as a hand is likely to be pinched between the opening and a fixed part of the vehicle. In the case of an opening such as a trunk lid, these pinches are particularly dangerous because the hydraulic or electric actuators used are particularly powerful given the weight of the hood.
Afin de sécuriser ce type d'ouvrant, il est connu des capteurs permettant de détecter des interférences avec les mouvements de l'ouvrant et d'agir en conséquence sur la cinématique desdits mouvements. To secure this type of opening, there are known sensors for detecting interference with the movements of the opening and act accordingly on the kinematics of said movements.
Cependant, on a constaté que lorsqu'une interférence a été détectée, l'arrêt du mouvement de l'ouvrant n'est pas immédiat. En effet, le temps de latence entre la détection de l'interférence et l'action de l'actionneur sur la cinématique du mouvement, dû à l'inertie du système, est tel que le mouvement de l'ouvrant se poursuit avec toute la force de l'actionneur pendant une courte période. Cette période est toutefois suffisamment longue pour permettre un mouvement de fermeture de l'ouvrant de l'ordre de quelques centimètres. Ainsi, malgré les moyens de détection s d'interférences, les mouvements de l'ouvrant ne sont pas complètement sécurisés. However, it has been found that when interference has been detected, the stop of the movement of the sash is not immediate. Indeed, the latency time between the detection of the interference and the action of the actuator on the movement kinematics, due to the inertia of the system, is such that the movement of the opening continues with the entire force of the actuator for a short time. This period is however long enough to allow a closing movement of the opening of the order of a few centimeters. Thus, despite the means of detection s interference, the movements of the opening are not completely secure.
L'invention vise à remédier à ce problème en proposant un moyen simple permettant d'arrêter le mouvement de M'ouvrant pendant un io laps de temps suffisant pour permettre à l'actionneur d'agir sur la cinématique des mouvements. The invention aims to remedy this problem by proposing a simple means for stopping the opening movement for a period of time sufficient to allow the actuator to act on the motion kinematics.
A cet effet, et selon un premier aspect, l'invention propose un véhicule automobile comprenant un ouvrant dont les mouvements de fermeture et/ou d'ouverture sont motorisés au moyen d'un actionneur qui est commandé par un dispositif, ledit dispositif comprenant des moyens de détection d'interférences avec les mouvements de l'ouvrant, les moyens de détection agissant sur l'actionneur de sorte à modifier la cinématique desdits mouvements, caractérisé en ce que l'actionneur comprend un organe à course morte, ladite course étant agencée pour, en cas de détection d'une interférence par les moyens de détection, arrêter le mouvement de l'ouvrant pendant un laps de temps suffisant pour permettre à l'actionneur d'agir sur la cinématique des mouvements. For this purpose, and according to a first aspect, the invention proposes a motor vehicle comprising an opening whose closing and / or opening movements are motorized by means of an actuator which is controlled by a device, said device comprising means for detecting interference with the movements of the opening, the detection means acting on the actuator so as to modify the kinematics of said movements, characterized in that the actuator comprises a dead-movement member, said stroke being arranged to, in the event of detection of interference by the detection means, stop the movement of the opening for a period of time sufficient to allow the actuator to act on the motion kinematics.
Ainsi, le mouvement de l'ouvrant est suffisamment sécurisé pour ne pas engendrer de blessures ou de dégâts sur des corps ou des objets. Thus, the movement of the opening is sufficiently secure not to cause injury or damage to bodies or objects.
D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit, faite en référence aux dessins annexés, dans lesquels: la figure 1 représente une vue schématique en coupe du capot de coffre du véhicule selon un mode de réalisation de l'invention, - la figure 2 représente une vue schématique en coupe du capot de coffre du véhicule selon un autre mode de réalisation de l'invention, la figure 3 représente un agrandissement de la zone 1111 illustrée io sur les figures 1 et 2, représentant l'organe à course morte de l'actionneur. Other objects and advantages of the invention will become apparent from the description which follows, made with reference to the accompanying drawings, in which: FIG. 1 represents a schematic sectional view of the trunk lid of the vehicle according to an embodiment of FIG. FIG. 2 shows a schematic sectional view of the trunk lid of the vehicle according to another embodiment of the invention; FIG. 3 represents an enlargement of the zone 1111 illustrated in FIGS. 1 and 2; representing the idle member of the actuator.
la figure 4 représente une vue schématique en coupe d'un bord périphérique du capot de coffre selon un mode de réalisation de 15 l'invention. Figure 4 shows a schematic sectional view of a peripheral edge of the trunk lid according to an embodiment of the invention.
Dans la description qui suit, il est décrit un mode de réalisation concernant un véhicule équipé d'un ouvrant tel qu'un capot de coffre. Notons cependant que la présente invention ne se limite pas à un véhicule comprenant un capot de coffre dont les mouvements sont motorisés mais peut également s'appliquer à tous type d'ouvrants dont les mouvements sont motorisés et notamment des ouvrants dont l'axe de rotation est vertical tel qu'une portière latérale. In the description which follows, there is described an embodiment concerning a vehicle equipped with an opening such as a trunk lid. Note however that the present invention is not limited to a vehicle comprising a trunk lid whose movements are motorized but can also be applied to all types of opening whose movements are motorized and including sashes whose axis of rotation is vertical such as a side door.
Le véhicule automobile comprend un coffre 4 équipé d'un capot 1. The motor vehicle comprises a trunk 4 equipped with a hood 1.
Le capot 1 est relié à la carrosserie 3 du véhicule par au moins une articulation 2 située au voisinage de la partie avant du coffre 4 et par au moins une articulation située au voisinage de la partie arrière du coffre 4 (non représenté). The cover 1 is connected to the body 3 of the vehicle by at least one hinge 2 located in the vicinity of the front part of the trunk 4 and at least one hinge located in the vicinity of the rear part of the trunk 4 (not shown).
Les articulations 2 sont des articulations libérables permettant au capot 1 de s'ouvrir de l'avant vers l'arrière ou de l'arrière vers l'avant. The joints 2 are releasable joints allowing the cover 1 to open from the front to the back or back to the front.
s Le véhicule comprend un actionneur du type vérin 5 agencé pour commander les mouvements de fermeture et/ou d'ouverture du capot 1. Le vérin 5 est un vérin à double effet. The vehicle comprises an actuator of the jack type 5 arranged to control the closing and / or opening movements of the cover 1. The jack 5 is a double-acting cylinder.
L'actionneur est commandé par un dispositif comprenant des lo moyens de détection des interférences avec les mouvements du capot. En cas de détection d'interférences, les moyens de détection agissent sur l'actionneur de sorte à modifier la cinématique des mouvements du capot 1. La modification de la cinématique du mouvement consiste à arrêter ou renverser ledit mouvement. The actuator is controlled by a device comprising means for detecting interference with the movements of the cover. In the event of detection of interference, the detection means act on the actuator so as to modify the kinematics of the movements of the cover 1. The modification of the motion kinematics consists in stopping or reversing said movement.
De façon connue, comme illustré sur la figure 1, le vérin 1 comprend un cylindre 6 qui est relié de façon pivotante à la carrosserie 3 selon un axe de pivotement 7, et une tige 8 qui est montée coulissante dans le cylindre 6 et qui est solidarisée, au capot 1 de façon articulée autour d'un second axe de pivotement 10. In known manner, as illustrated in Figure 1, the cylinder 1 comprises a cylinder 6 which is pivotally connected to the body 3 according to a pivot axis 7, and a rod 8 which is slidably mounted in the cylinder 6 and which is secured to the cover 1 in an articulated manner about a second pivot axis 10.
La figure 3 représente de façon détaillée l'organe 12 à course morte. Figure 3 shows in detail the organ 12 with a dead stroke.
L'organe 12 à course morte est constitué d'une tête 13 solidaire du capot au moyen d'une projection 14 pouvant coulisser dans un évidemment 15 formé à l'extrémité 9 de la tige 8 du vérin 5. Ainsi, la tige 8 est solidarisée au capot par l'intermédiaire de l'organe à course morte 12. The member 12 with a dead stroke consists of a head 13 integral with the hood by means of a projection 14 slidable in a recess 15 formed at the end 9 of the rod 8 of the cylinder 5. Thus, the rod 8 is secured to the hood via the dead-race member 12.
La dimension axiale de l'évidemment 15 forme la course morte 16. Plus précisément, la course morte 16 est réalisée par l'espace libre situé entre la tête 13 et le rétrécissement 17 de l'évidemment 15. The axial dimension of the recess 15 forms the dead travel 16. More specifically, the dead travel 16 is made by the free space between the head 13 and the narrowing 17 of the recess 15.
Lors de la fermeture du capot 1 par un vérin 5, le poids du capot 1 pousse l'organe 12 vers le bas. Ainsi, la tête 13 de l'organe 12 se situe au voisinage du fond 18 de l'évidemment 15. When the cover 1 is closed by a jack 5, the weight of the cover 1 pushes the member 12 downwards. Thus, the head 13 of the organ 12 is in the vicinity of the bottom 18 of the recess 15.
Lorsque le capot 1 rencontre un objet ou un corps, la tête 13 de l'organe 12 s'écarte du fond 18 de l'évidemment 15. Ainsi, la tête 13 coulisse dans l'évidemment 15 entre deux butées, d'une position où elle est en butée contre le fond 18 de l'évidement 15 lo vers une position où elle est en butée contre le rétrécissement 17 de l'évidemment 15. When the cover 1 meets an object or a body, the head 13 of the member 12 deviates from the bottom 18 of the recess 15. Thus, the head 13 slides in the recess 15 between two stops, a position where it is in abutment against the bottom 18 of the recess 15 lo to a position where it is in abutment against the narrowing 17 of the recess 15.
Le déplacement de l'organe 12 permet d'annuler le mouvement du capot 1. The displacement of the member 12 makes it possible to cancel the movement of the cover 1.
Notons que la course 16 de l'organe 12 doit être agencée pour arrêter le mouvement du capot pendant un laps de temps suffisant pour permettre à l'actionneur d'agir sur la cinématique du mouvement. Note that the stroke 16 of the member 12 must be arranged to stop the movement of the cover for a period of time sufficient to allow the actuator to act on the motion kinematics.
Afin d'éviter le déplacement par à-coups de l'organe 12 dans l'évidemment 15, les déplacements de la tête 13 de l'organe 12 dans l'évidemment 15 sont contraints par un élément élastique disposé entre la tête 13 de l'organe 12 et le rétrécissement 17 de l'évidemment 15. In order to avoid the jerking movement of the member 12 in the recess 15, the displacements of the head 13 of the member 12 in the recess 15 are constrained by an elastic element disposed between the head 13 of the organ 12 and the narrowing 17 of the recess 15.
Selon le mode de réalisation détaillé sur la figure 3, l'élément élastique est un ressort 19. According to the embodiment detailed in FIG. 3, the elastic element is a spring 19.
Cependant, dans d'autre mode de réalisation non représenté, l'élément élastique est un fluide tel qu'un liquide ou un gaz sous pression. Le fluide circule entre deux chambres séparées par un ajutage. Le fluide est mis en mouvement par la tête fonctionnant à la manière d'un piston, l'ajutage permettant de freiner le mouvement. However, in another embodiment not shown, the elastic element is a fluid such as a liquid or a gas under pressure. The fluid flows between two chambers separated by a nozzle. The fluid is moved by the head operating in the manner of a piston, the nozzle to slow the movement.
Dans le mode de réalisation détaillée sur la figure 3, les moyens de détection des interférences comprennent un capteur détectant la position de la tête 13 dans l'évidemment 15. L'organe à course morte 12 est composé d'un ergot 20 solidaire de la tête 13. L'ergot 20 comprend un bras 21 coulissant dans un boîtier 22 solidaire de la tige 8 du vérin 5 et possédant un capteur. Le bras 21 permet au io capteur de détecter un déplacement de la position de la tête 13 dans l'évidemment. In the embodiment detailed in FIG. 3, the interference detection means comprise a sensor detecting the position of the head 13 in the recess 15. The dead-movement member 12 is composed of a lug 20 integral with the head 13. The lug 20 comprises an arm 21 sliding in a housing 22 integral with the rod 8 of the cylinder 5 and having a sensor. The arm 21 allows the sensor to detect a displacement of the position of the head 13 in the recess.
Dans un mode de réalisation, le capteur utilisé est un capteur à contact. Le bras 21 est en contact avec ledit capteur lorsque la tête 13 est en butée contre le fond 18 de l'évidemment 15. Lorsque le bras 21 n'est plus en contact avec le capteur, un signal est envoyé au dispositif commandant l'actionneur afin de modifier la cinématique du mouvement du capot 1. In one embodiment, the sensor used is a contact sensor. The arm 21 is in contact with said sensor when the head 13 is in abutment against the bottom 18 of the recess 15. When the arm 21 is no longer in contact with the sensor, a signal is sent to the device controlling the actuator to change the kinematics of the movement of the hood 1.
Notons que les moyens de détection d'interférences ne se limitent pas à un capteur permettant de détecter un déplacement de l'organe 12 à course morte. En effet, les moyens de détection peuvent par exemple être des capteurs à contact disposés sur la périphérie du capot 1. Note that the interference detection means are not limited to a sensor for detecting a displacement of the member 12 with a dead stroke. Indeed, the detection means may for example be contact sensors disposed on the periphery of the cover 1.
Dans les cas où le poids du capot 1 est trop élevé, il est prévu d'ajouter un ou plusieurs équilibreurs 23 comme ceci est illustré à la figure 2. In cases where the weight of the cover 1 is too high, it is expected to add one or more balancers 23 as shown in Figure 2.
L'utilisation d'un tel équilibreur 23 permet de compenser une partie du poids du capot 1 et de limiter ainsi le pincement résiduel dû au poids du capot 1. The use of such a balancer 23 makes it possible to compensate for a part of the weight of the cover 1 and thus to limit the residual pinch due to the weight of the cover 1.
Dans le mode de réalisation représenté sur la figure 2, le ou les équilibreurs 23 sont placés au voisinage des articulations du capot 1. In the embodiment shown in FIG. 2, the balancer or balancers 23 are placed in the vicinity of the joints of the cover 1.
Dans le mode de réalisation illustré figure 2, l'articulation avant du capot 1 sur la carrosserie 3 du véhicule est formée par deux biellettes 24,25 formant un quadrilatère déformable. Chaque biellette 24, 25 est fixée à une de ses extrémités au capot 1 et à l'autre extrémité à la carrosserie 3 du véhicule. L'équilibreur 23, qui io peut notamment être un vérin à gaz sous pression, est fixé à une de ses extrémités à la carrosserie 3 et pousse une biellette 25 d'articulation du capot 1. In the embodiment illustrated in FIG. 2, the front articulation of the hood 1 on the body 3 of the vehicle is formed by two links 24, 25 forming a deformable quadrilateral. Each link 24, 25 is fixed at one of its ends to the hood 1 and at the other end to the body 3 of the vehicle. The balancer 23, which can in particular be a gas cylinder under pressure, is fixed at one of its ends to the body 3 and pushes a connecting rod 25 of the cover 1.
Bien que cela ne soit pas représenté sur la figure 2, des 15 équilibreurs 23 peuvent également être utilisés sur l'articulation arrière du capot 1 ou éventuellement à un autre endroit du capot 1. Although not shown in FIG. 2, balancers 23 may also be used on the rear articulation of cover 1 or possibly elsewhere on cover 1.
Afin de limiter davantage l'effet de pincement dû au poids du capot 1, on peut prévoir dans la zone de pincement périphérique 26 du capot 1, située entre la carrosserie 3 du véhicule et le capot 1, un dispositif illustré à la figure 4. In order to further limit the pinch effect due to the weight of the cover 1, provision can be made in the peripheral nipping zone 26 of the cover 1, located between the bodywork 3 of the vehicle and the cover 1, a device shown in FIG.
Un bourrelet 27 de matière souple est placé dans la zone de pincement 26, au voisinage du bord intérieur 29 de capot 1, de sorte à amortir la pression exercée par le poids du capot 1 sur l'objet ou la partie de corps humain coincé. A bead 27 of flexible material is placed in the nip 26, in the vicinity of the inner edge 29 of the hood 1, so as to damp the pressure exerted by the weight of the cover 1 on the object or body part jammed.
Le bourrelet 27 est réalisé en matériau synthétique tel qu'une mousse, cette mousse pouvant être une mousse en polyuréthane. The bead 27 is made of synthetic material such as a foam, this foam may be a polyurethane foam.
Dans le mode de réalisation représenté figure 4, le bourrelet 27 est supporté par une pièce en matière dure 28 elle-même fixée sur le bord intérieur 29 du capot 1.
