Description

TITRE : SYSTÈME DE LEVAGE ET DE STABILISATION D’UN VEHICULE TITLE: VEHICLE LIFTING AND STABILIZATION SYSTEM

Domaine technique Technical field

La présente invention concerne les systèmes de crics permettant le levage ou la stabilisation d’un flanc d’un véhicule, par exemple un véhicule automobile ou un véhicule utilitaire doté de caissons de stockage. The present invention relates to jack systems for lifting or stabilizing a side of a vehicle, for example a motor vehicle or a utility vehicle equipped with storage boxes.

La présente invention vise à constituer un système qui permette à la fois le levage et la stabilisation du véhicule, par exemple pour faciliter un déchargement latéral du véhicule ou intervenir sur une roue du véhicule. The present invention aims to constitute a system which allows both the lifting and the stabilization of the vehicle, for example to facilitate lateral unloading of the vehicle or to intervene on a wheel of the vehicle.

Techniques antérieures Previous techniques

On connaît des systèmes de crics qui permettent de réaliser un levage ou la stabilisation d’un flanc d’un véhicule grâce à un mécanisme de compression d’un fluide. There are known jack systems that allow lifting or stabilization of the side of a vehicle using a fluid compression mechanism.

D’ autre part, il existe des systèmes distincts permettant la stabilisation du véhicule, par des mécanismes hydrauliques. On the other hand, there are separate systems that allow the stabilization of the vehicle, by hydraulic mechanisms.

Aucun système connu ne combine à la fois un mécanisme de levage du flanc du véhicule et la stabilisation dudit véhicule. No known system combines both a vehicle side lifting mechanism and vehicle stabilization.

Exposé de l’invention Disclosure of the invention

L’invention a pour but de pallier au moins certains des inconvénients précités et de proposer un système capable de cumuler des avantages de rapidité, simplicité et fiabilité pour sa mise en œuvre, et ce pour combiner à la fois le levage et la stabilisation du véhicule. The invention aims to overcome at least some of the aforementioned drawbacks and to propose a system capable of combining the advantages of speed, simplicity and reliability for its implementation, and this to combine both the lifting and the stabilization of the vehicle.

Au vu de ce qui précède, l ’ invention a pour obj et un système de levage et de stabilisation d’un véhicule comportant une platine supérieure apte à soutenir ledit véhicule lors de son levage ou de sa stabilisation par ledit système, une platine inférieure destinée à fournir au véhicule une liaison au sol lors de son levage ou de sa stabilisation, des moyens de levage ou de stabilisation aptes à écarter ou rapprocher la platine supérieure de la platine inférieure et comportant une première bielle principale et une deuxième bielle principale liée par une liaison pivot principale à la première bielle principale, la première bielle principale et la deuxième bielle principale comportant chacune d’une part une extrémité supérieure liée à la platine supérieure et d’ autre part une extrémité inférieure liée à la platine inférieure par une rainure dans la platine inférieure, le système de levage ou de stabilisation comportant en outre un moteur réversible configuré pour l ’ entrainement dans un sens ou dans l ’ autre des bielles principales autour de la liaison pivot principale, le système comportant en outre un système de renforcement comportant une bielle secondaire inférieure liée à la platine inférieure et à la deuxième bielle principale et une bielle secondaire supérieure reliant ladite bielle secondaire inférieure à la platine supérieure et liée à la première bielle principale par une première liaison pivot secondaire et à la deuxième bielle principale par une deuxième liaison pivot secondaire. In view of the foregoing, the subject of the invention is a system for lifting and stabilizing a vehicle comprising an upper plate capable of supporting said vehicle during its lifting or stabilization by said system, a lower plate intended to provide the vehicle with a connection to the ground during its lifting or stabilization, lifting or stabilizing means capable of moving the upper plate away from or closer to the lower plate and comprising a first main connecting rod and a second main connecting rod connected by a main pivot connection to the first main connecting rod, the first main connecting rod and the second main connecting rod each comprising on the one hand an upper end connected to the upper plate and on the other hand a lower end connected to the lower plate by a groove in the lower plate, the lifting or stabilizing system further comprising a reversible motor configured to drive the main connecting rods in one direction or the other around the main pivot connection, the system further comprising a reinforcement system comprising a lower secondary connecting rod connected to the lower plate and to the second main connecting rod and an upper secondary connecting rod connecting said lower secondary connecting rod to the upper plate and connected to the first main connecting rod by a first secondary pivot connection and to the second main connecting rod by a second secondary pivot connection.

De préférence, les moyens de levage ou de stabilisation comportent une vis sans fin et le moteur réversible est couplé à ladite vis sans fin et configuré pour pouvoir entraîner celle-ci en rotation sur elle-même, et au moins une des extrémités supérieures est liée en liaison hélicoïdale à ladite vis sans fin de sorte qu’un entrainement en rotation de la vis sans fin sur elle-même entraine la translation de ladite extrémité supérieure le long de ladite vis sans fin. Preferably, the lifting or stabilizing means comprise a worm screw and the reversible motor is coupled to said worm screw and configured to be able to drive the latter in rotation on itself, and at least one of the upper ends is linked in a helical connection to said worm screw so that a rotational drive of the worm screw on itself causes the translation of said upper end along said worm screw.

Par exemple, la vis sans fin comporte deux sens de vissage opposés et les extrémités supérieures sont chacune liées en liaison hélicoïdale à ladite vis sans fin selon un sens de vissage opposé à l ’ autre, de sorte qu’un entrainement en rotation de la vis sans fin sur elle-même par le moteur réversible entraine en translation les deux extrémités supérieures dans des sens opposés le long de ladite vis sans fin. For example, the worm screw has two opposite screwing directions and the upper ends are each linked in a helical connection to said worm screw in a screwing direction opposite to the other, so that a rotational drive of the worm screw on itself by the reversible motor drives the two upper ends in translation in opposite directions along said worm screw.

Avantageusement, la première bielle principale est renforcée par une bielle de renforcement principale placée en parallèle de ladite première bielle principale et liée à celle-ci par son extrémité inférieure, par la première liaison pivot secondaire et par la liaison pivot principale, et dans lequel la bielle secondaire inférieure est renforcée par une bielle de renforcement secondaire placée en parallèle de ladite bielle secondaire inférieure et liée à celle-ci par son extrémité inférieure, par son extrémité supérieure et par la deuxième liaison pivot secondaire. Advantageously, the first main connecting rod is reinforced by a main reinforcing connecting rod placed in parallel with said first main connecting rod and connected thereto by its lower end, by the first secondary pivot connection and by the main pivot connection, and in which the lower secondary connecting rod is reinforced by a secondary reinforcing connecting rod placed in parallel with said lower secondary connecting rod and connected thereto by its lower end, by its upper end and by the second secondary pivot connection.

Selon une forme de réalisation, le système est adapté pour tenir dans un parallélépipède de l ’ ordre de six cent millimètres par cent millimètres par cent millimètres à l ’ état replié. According to one embodiment, the system is adapted to fit into a parallelepiped of the order of six hundred millimeters by one hundred millimeters by one hundred millimeters in the folded state.

Description détaillée Detailed description

La Figure 1 illustre, en vue en perspective, un système de levage et de stabilisation d’un véhicule 1 selon l ’ invention, intégré sur ledit véhicule 2.Figure 1 illustrates, in perspective view, a lifting and stabilization system for a vehicle 1 according to the invention, integrated on said vehicle 2.

Le repère XYZ classiquement utilisé en conception automobile, désigne la direction longitudinale avant-arrière du véhicule par l ’ axe X orienté vers l ’ arrière dudit véhicule, la direction transversale par l ’ axe Y orienté vers la droite dudit véhicule, et la direction verticale par l ’ axe Z orienté vers le haut dudit véhicule. The XYZ reference system, conventionally used in automobile design, designates the front-rear longitudinal direction of the vehicle by the X axis oriented towards the rear of said vehicle, the transverse direction by the Y axis oriented towards the right of said vehicle, and the vertical direction by the Z axis oriented towards the top of said vehicle.

Comme illustré par la Figure 2, le système de levage et de stabilisation 1 est intégré au véhicule 2 par une trappe d’ accès 3 qui s’ étend parallèlement à l ’ axe longitudinal X et qui permet d’ escamoter ou de sortir en saillie ledit système 1 lorsqu’ il est fixé sur la caisse du véhicule 2. As illustrated in Figure 2, the lifting and stabilizing system 1 is integrated into the vehicle 2 by an access hatch 3 which extends parallel to the longitudinal axis X and which allows said system 1 to be retracted or projected when it is fixed to the body of the vehicle 2.

Le système 1 est positionné sur un flanc du véhicule 2, préférentiellement dans un plan passant par les axes X et Y et par le centre de gravité du véhicule 2. The system 1 is positioned on a side of the vehicle 2, preferably in a plane passing through the X and Y axes and through the center of gravity of the vehicle 2.

Les mécanismes du système 1 sont intégrés à l ’ intérieur de la carrosserie du véhicule 2 et fixés sur la caisse du véhicule 2, notamment sur son châssis. The mechanisms of system 1 are integrated inside the body of vehicle 2 and fixed to the body of vehicle 2, in particular to its chassis.

La trappe d’ accès 3 permet le rangement du système 1 dans le véhicule 2 et sa protection contre les agressions extérieures, par exemple grâce à un couvercle pivotant de la trappe d’ accès qui est intégré à la peau de la carrosserie. The access hatch 3 allows the system 1 to be stored in the vehicle 2 and protected against external aggression, for example by means of a pivoting cover of the access hatch which is integrated into the skin of the bodywork.

La trappe d’ accès 3 permet également de cacher de la vue le système 1 et de n’ avoir aucun impact sur l ’ aérodynamisme du véhicule 2. The access hatch 3 also makes it possible to hide the system 1 from view and to have no impact on the aerodynamics of the vehicle 2.

Comme illustré par la Figure 3 , le système 1 comporte une platine supérieure 4 apte à soutenir ledit véhicule 2 lors de son levage ou de sa stabilisation par ledit système 1 , une platine inférieure 5 destinée à fournir au véhicule 2 une liaison au sol lors de son levage ou de sa stabilisation, et des moyens de levage ou de stabilisation 6 aptes à écarter ou rapprocher la platine supérieure 4 de la platine inférieure 5. As illustrated in Figure 3, the system 1 comprises an upper plate 4 capable of supporting said vehicle 2 during its lifting or stabilization by said system 1, a lower plate 5 intended to provide the vehicle 2 with a connection to the ground during its lifting or stabilization, and lifting or stabilization means 6 capable of moving the upper plate 4 away from or closer to the lower plate 5.

La platine supérieure 4 vise au soutenir le véhicule 2 lors de son levage ou de sa stabilisation. The upper plate 4 is intended to support the vehicle 2 during its lifting or stabilization.

Par « levage » on entend le soulèvement d’un premier flanc du véhicule 2 par rapport à un deuxième flanc du véhicule 2 opposé au premier flanc. By “lifting” is meant the lifting of a first side of the vehicle 2 relative to a second side of the vehicle 2 opposite the first side.

Ainsi, pour un véhicule à quatre roues, les deux roues du même côté du véhicule 2 qui sont soulevées lors du levage n’ ont plus de contact avec le sol, tandis que la liaison au sol du véhicule 2 est assurée par une ou deux autres roues du véhicule 2 opposées aux roues soulevées et par le système 1. Thus, for a four-wheeled vehicle, the two wheels on the same side of vehicle 2 which are lifted during lifting no longer have contact with the ground, while the ground connection of vehicle 2 is ensured by one or two other wheels of vehicle 2 opposite the lifted wheels and by system 1.

Lors du levage, le véhicule 2 pivote suivant un axe sensiblement parallèle à l ’ axe longitudinal X, passant par les deux contacts au sol fournis par les roues du côté opposé. When lifting, the vehicle 2 pivots along an axis substantially parallel to the longitudinal axis X, passing through the two ground contacts provided by the wheels on the opposite side.

Grâce à ce fonctionnement, aucune contrainte de torsion de caisse en position levée n’ est observée, et la stabilité du véhicule 2 levé est augmentée puisque la voiture se lève parallèlement au sol sur trois points de liaison au sol, à savoir le système 1 et les roues opposées du véhicule 2. Thanks to this operation, no torsional stress on the body in the raised position is observed, and the stability of the raised vehicle 2 is increased since the car rises parallel to the ground on three ground connection points, namely system 1 and the opposite wheels of vehicle 2.

Le déploiement des bielles peut être réalisé pour un levage jusqu’ au maximum de déploiement du système 1 , ce qui permet par exemple de changer une des roues soulevées du véhicule 2, ou être réalisée partiellement jusqu’ à une position intermédiaire de déploiement dans laquelle toutes les roues du véhicule 2 continuent à assurer une liaison au sol, pour une stabilisation, et dans laquelle le système 1 est déployé suffisamment pour que la platine inférieure 5 touche le sol et assure une liaison au sol complémentaire au véhicule 2 pour le stabiliser. The deployment of the connecting rods can be carried out for lifting up to the maximum deployment of the system 1, which allows for example to change one of the raised wheels of the vehicle 2, or be carried out partially up to an intermediate deployment position in which all the wheels of the vehicle 2 continue to provide a connection to the ground, for stabilization, and in which system 1 is deployed sufficiently so that the lower plate 5 touches the ground and provides an additional ground connection to the vehicle 2 to stabilize it.

Pour une stabilisation, on peut prévoir de déployer un exemplaire du système 1 de chaque côté du véhicule 2. For stabilization, one example of system 1 can be deployed on each side of vehicle 2.

La stabilisation consiste donc en un déploiement du système 1 hors du véhicule 2 tel que la platine inférieure 5 atteigne le sol sans soulever les deux roues du même flanc du véhicule 2 que le système 1 , de manière à assurer une fonction de maintien horizontal du véhicule 2. Stabilization therefore consists of deploying the system 1 outside the vehicle 2 such that the lower plate 5 reaches the ground without lifting the two wheels on the same side of the vehicle 2 as the system 1, so as to ensure a horizontal holding function for the vehicle 2.

Par exemple, la position de stabilisation correspond à un déploiement du système 1 de l ’ ordre de cent soixante-cinq millimètres selon l ’ axe Z, permettant un contact au sol depuis le bas de caisse du véhicule 2. For example, the stabilization position corresponds to a deployment of system 1 of the order of one hundred and sixty-five millimeters along the Z axis, allowing contact with the ground from the underbody of vehicle 2.

La platine supérieure 4 est configurée pour pouvoir fixer le système 1 sur la caisse du véhicule, par exemple grâce à des perçage permettant son vissage sur ladite caisse du véhicule 2. The upper plate 4 is configured to be able to fix the system 1 on the body of the vehicle, for example by means of drilling allowing it to be screwed onto said body of the vehicle 2.

La fixation de la platine supérieure 4 permet la rigidité du système de levage ou de stabilisation en suppriment des degrés de liberté par rapport aux systèmes de crics classiques qui présentent généralement le danger de pouvoir tourner sur eux-mêmes autour de l ’ axe X ou autour de l ’ axe Z . The fixing of the upper plate 4 allows the rigidity of the lifting or stabilization system by removing degrees of freedom compared to conventional jack systems which generally present the danger of being able to rotate on themselves around the X axis or around the Z axis.

Les moyens de levage ou de stabilisation 6 comportent une première bielle principale 7 et une deuxième bielle principale 1 1 liée par une liaison pivot principale 18 à la première bielle principale 7. The lifting or stabilizing means 6 comprise a first main connecting rod 7 and a second main connecting rod 11 linked by a main pivot connection 18 to the first main connecting rod 7.

L’utilisation de bielles permet que le déploiement soit rapide et que le repliement soit très peu encombrant. The use of connecting rods allows for rapid deployment and very space-saving folding.

Les deux bielles principales 7, 1 1 sont donc croisées l ’une par rapport à l ’ autre et sont aptes à tourner l ’une par rapport à l ’ autre autour de la liaison pivot principale 18 située sensiblement en leurs centres, ce qui éloigne ou rapproche leurs extrémités selon l ’ axe Z . The two main connecting rods 7, 11 are therefore crossed relative to each other and are able to rotate relative to each other around the main pivot connection 18 located substantially at their centers, which moves their ends further apart or closer together along the Z axis.

La section des bielles 7, 1 1 est par exemple de vingt millimètres par cinq millimètres lorsqu’ elles sont réalisées en acier. The section of the connecting rods 7, 1 1 is for example twenty millimeters by five millimeters when they are made of steel.

Pour optimiser le poids de l ’ ensemble des bielles, il est possible d’utiliser des bielles en tôle emboutie intégrant des raidisseurs. To optimize the weight of the entire connecting rod assembly, it is possible to use stamped sheet metal connecting rods incorporating stiffeners.

Le système 1 comporte en outre un système de renforcement comportant une bielle secondaire inférieure 9 et une bielle secondaire supérieure 10. The system 1 further comprises a reinforcement system comprising a lower secondary connecting rod 9 and an upper secondary connecting rod 10.

La bielle secondaire inférieure 9 est liée à la platine inférieure 5 et à la deuxième bielle principale 1 1. The lower secondary connecting rod 9 is connected to the lower plate 5 and to the second main connecting rod 1 1.

La bielle secondaire supérieure 10 relie ladite bielle secondaire inférieure 9 à la platine supérieure 4 et liée à la première bielle principale 7 par une première liaison pivot secondaire 20 et à la deuxième bielle principale 1 1 par une deuxième liaison pivot secondaire 17. The upper secondary connecting rod 10 connects said lower secondary connecting rod 9 to the upper plate 4 and linked to the first main connecting rod 7 by a first secondary pivot connection 20 and to the second main connecting rod 11 by a second secondary pivot connection 17.

La première bielle principale 7 et la deuxième bielle principale 1 1 comportent chacune d’une part une extrémité supérieure 21 , 22 liée à la platine supérieure et d’ autre part une extrémité inférieure 13 , 15 liée à la platine inférieure 5 par une rainure 12, 14 dans la platine inférieure 5. The first main connecting rod 7 and the second main connecting rod 11 each comprise on the one hand an upper end 21, 22 connected to the upper plate and on the other hand a lower end 13, 15 connected to the lower plate 5 by a groove 12, 14 in the lower plate 5.

La première rainure 14 permet de faire coulisser l’ extrémité inférieure 15 de la première bielle principale 7 parallèlement à l ’ axe longitudinal X lors d’un entrainement en rotation de ladite première bielle principale 7 autour de la liaison pivot principale 18. The first groove 14 allows the lower end 15 of the first main connecting rod 7 to slide parallel to the longitudinal axis X during rotation of said first main connecting rod 7 around the main pivot connection 18.

La deuxième rainure 12 permet de faire coulisser l ’ extrémité inférieure 13 de la deuxième bielle principale 1 1 parallèlement à l ’ axe longitudinal X lors d’un entrainement en rotation de ladite deuxième bielle principale 1 1 autour de la liaison pivot principale 18. The second groove 12 allows the lower end 13 of the second main connecting rod 11 to slide parallel to the longitudinal axis X during rotation of said second main connecting rod 11 around the main pivot connection 18.

Les première et deuxième rainures 12, 14 peuvent être doublées de part et d’ autre des bielles principales 8, 1 1 de manière à améliorer et équilibrer le guidage en translation des extrémités inférieures 13 , 15, comme illustré par la Figure 3. The first and second grooves 12, 14 can be doubled on either side of the main connecting rods 8, 11 so as to improve and balance the translational guidance of the lower ends 13, 15, as illustrated in Figure 3.

Le système de renforcement permet de maximiser la stabilisation en prenant en charge le besoin d’ horizontalité du véhicule 2 pendant certaines manœuvres, par exemple de chargement et de déchargement d’un volume du véhicule 2. The reinforcement system makes it possible to maximize stabilization by supporting the need for horizontality of the vehicle 2 during certain maneuvers, for example loading and unloading a volume of the vehicle 2.

Notamment, lors des opérations de chargement et de déchargement du véhicule 2, par exemple par un gerbeur manuel ou à l ’ aide d’un engin mécanisés tel qu’un chariot à fourches, la facilité de mise en place est conditionnée par un positionnement du véhicule 2 le plus horizontal possible. In particular, during the loading and unloading operations of the vehicle 2, for example by a manual stacker or using a mechanized machine such as a forklift, the ease of installation is conditioned by positioning the vehicle 2 as horizontally as possible.

En outre, le système 1 est aussi un cric de levage ou de stabilisation du véhicule 2, permettant par exemple l ’ échange d’une roue. In addition, the system 1 is also a jack for lifting or stabilizing the vehicle 2, allowing for example the exchange of a wheel.

La présence des rainures 12, 14 dans lesquelles peuvent coulisser les extrémités inférieures 13 , 15 des bielles principales 9, 1 1 ainsi que celle des bielles secondaires inférieure 9 et supérieure 10 permettent d’ obtenir cette horizontalité du véhicule 2 lors du levage. The presence of the grooves 12, 14 in which the lower ends 13, 15 of the main connecting rods 9, 11 can slide, as well as that of the lower 9 and upper 10 secondary connecting rods, make it possible to obtain this horizontality of the vehicle 2 during lifting.

Le système de levage ou de stabilisation 6 comporte en outre un moteur réversible 25, peut être un moteur alimenté électriquement, configuré pour l ’ entrainement dans un sens ou dans l ’ autre des bielles principales 7, 1 1 autour de la liaison pivot principale 18. The lifting or stabilizing system 6 further comprises a reversible motor 25, which may be an electrically powered motor, configured to drive the main connecting rods 7, 11 in one direction or the other around the main pivot connection 18.

Avantageusement, la première bielle principale 7 est renforcée par une bielle de renforcement principale 8 placée en parallèle de ladite première bielle principale 7 et liée à celle-ci par son extrémité inférieure 15, par la première liaison pivot secondaire 20 et par la liaison pivot principale 18. Advantageously, the first main connecting rod 7 is reinforced by a main reinforcing connecting rod 8 placed in parallel with said first connecting rod. main 7 and connected to it by its lower end 15, by the first secondary pivot connection 20 and by the main pivot connection 18.

La bielle secondaire inférieure peut être en outre renforcée par une bielle de renforcement secondaire 9 placée en parallèle de ladite bielle secondaire inférieure 9 et liée à celle-ci par son extrémité inférieure 16, par son extrémité supérieure 19 et par la deuxième liai son pivot secondaire 17. The lower secondary connecting rod may be further reinforced by a secondary reinforcing connecting rod 9 placed in parallel with said lower secondary connecting rod 9 and linked to the latter by its lower end 16, by its upper end 19 and by the second link its secondary pivot 17.

De préférence, les moyens de levage ou de stabilisation 6 comportent une vis sans fin 23 et le moteur réversible 25 est couplé à ladite vis sans fin 23 et configuré pour pouvoir entraîner celle-ci en rotation sur elle-même, et au moins une des extrémités supérieures 21 , 22 est liée en liaison hélicoïdale à ladite vis sans fin 23. Preferably, the lifting or stabilizing means 6 comprise a worm screw 23 and the reversible motor 25 is coupled to said worm screw 23 and configured to be able to drive the latter in rotation on itself, and at least one of the upper ends 21, 22 is linked in a helical connection to said worm screw 23.

La vis sans fin 23 est par exemple maintenue à la platine supérieure 4 par ses deux extrémités 24 qui sont maintenue par deux paliers à bagues de la platine supérieure 4. The worm screw 23 is for example held to the upper plate 4 by its two ends 24 which are held by two ring bearings of the upper plate 4.

Ainsi, un entrainement en rotation de la vis sans fin 23 sur elle-même entraine la translation de ladite extrémité supérieure 21 , 22 le long de ladite vis sans fin 23. Thus, a rotational drive of the worm screw 23 on itself causes the translation of said upper end 21, 22 along said worm screw 23.

Ainsi, le moteur réversible 25 permet l ’utilisation du système 1 pour son déploiement ou son repliement sans manipulation mécanique par l ’utilisateur. Thus, the reversible motor 25 allows the use of the system 1 for its deployment or folding without mechanical manipulation by the user.

On peut prévoir que l ’ activation du moteur réversible 25 et son sens d’ activation soient commandés par un système de commande du véhicule et couplés à une alimentation électrique du véhicule 2, de manière à permettre à l ’utilisateur l ’utilisation du système 1 directement depuis le tableau de bord du véhicule 2 regroupant d’ autres commandes du véhicule 2. It can be provided that the activation of the reversible motor 25 and its direction of activation are controlled by a vehicle control system and coupled to an electrical power supply of the vehicle 2, so as to allow the user to use the system 1 directly from the dashboard of the vehicle 2 grouping together other controls of the vehicle 2.

Le système de commande comporte par exemple trois commandes indépendantes pour des positions préenregistrées par système 1 sur un flanc du véhicule 2, permettant les commandes droite ou gauche avec les positions « rangé », dans laquelle le système 1 est entièrement escamoté dans la trappe d’ accès 3 , « stabilisateur » dans laquelle le système 1 est déployé dans une position intermédiaire de sorte que la platine inférieure 5 atteigne le sol sans soulever de roue du véhicule 2, et « cric », dans laquelle le déploiement des bielles est maximal et au moins une roue du véhicule 2 est soulevée du sol . The control system comprises for example three independent controls for positions pre-recorded by system 1 on a side of the vehicle 2, allowing the right or left controls with the positions “stored”, in which the system 1 is completely retracted into the access hatch 3, “stabilizer” in which the system 1 is deployed in an intermediate position so that the lower plate 5 reaches the ground without lifting a wheel of the vehicle 2, and “jack”, in which the deployment of the connecting rods is maximum and at least one wheel of the vehicle 2 is raised from the ground.

Le moteur réversible 25 peut tourner dans un premier sens pour une mise en rotation de la vis sans fin 23 dans le sens de l ’ écartement des platines inférieure 5 et supérieure 4, pour le déploiement du système 1 permettant le levage ou la stabili sation d’un véhicule 2. The reversible motor 25 can rotate in a first direction to rotate the worm screw 23 in the direction of the separation of the lower 5 and upper 4 plates, for the deployment of the system 1 allowing the lifting or stabilization of a vehicle 2.

Par exemple, la vis sans fin 23 comporte deux sens de vissage opposés et les extrémités supérieures 21 , 22 sont chacune liées en liaison hélicoïdale à ladite vis sans fin 23 selon un sens de vissage opposé à l ’ autre, de sorte qu’un entrainement en rotation de la vis sans fin 23 sur elle-même par le moteur réversible 25 entraine en translation les deux extrémités supérieures 21 , 22 dans des sens opposés le long de ladite vis sans fin 23. For example, the worm screw 23 has two opposite screwing directions and the upper ends 21, 22 are each linked in a helical connection to said worm screw 23 in a screwing direction opposite to the other, so that a rotational drive of the worm screw 23 on itself by the reversible motor 25 drives the two upper ends 21, 22 in translation in opposite directions along said worm screw 23.

Ainsi, dans cette configuration illustrée par la Figure 3 , les deux extrémités supérieures 21 ,22 sont déplacés symétriquement par rapport au moteur réversible 25 grâce à la rotation vis sans fin 23. Thus, in this configuration illustrated by Figure 3, the two upper ends 21, 22 are moved symmetrically relative to the reversible motor 25 thanks to the rotation of the worm screw 23.

Cette configuration de la vis sans fin 23 à double sens permet l ’ optimisation du dimensionnement de la fonction de levage ou de stabilisation, ce qui permet au système 1 d’ être intégrée dans le faible volume de la trappe d’ accès 3 située entre un longeron longitudinal de la caisse du véhicule 2 et la peau du bas de la caisse du véhicule 2. This configuration of the two-way worm screw 23 allows the optimization of the dimensioning of the lifting or stabilization function, which allows the system 1 to be integrated into the small volume of the access hatch 3 located between a longitudinal side member of the vehicle body 2 and the skin of the bottom of the vehicle body 2.

Un entrainement du moteur réversible 25 dans un premier sens entraine le rapprochement relatif des deux extrémités supérieures 21 ,22, qui sont entraînées vers le centre de la vis sans fin 23 , ce qui repousse la platine inférieure 5 vers le sol et déploie le système 1 sensiblement parallèlement à l ’ axe Z . Driving the reversible motor 25 in a first direction causes the two upper ends 21, 22 to come together relatively, which are driven towards the centre of the worm screw 23, which pushes the lower plate 5 towards the ground and deploys the system 1 substantially parallel to the Z axis.

Le système de renforcement permet la conservation du parallélisme entre les platines inférieure 5 et supérieure 4, pendant les mouvements de descente et de montée de la platine inférieure 5 servant de base d’ appui au véhicule 2 avec la platine supérieure 5 fixée sur un longeron longitudinal sur un flanc de la caisse du véhicule 2. The reinforcement system allows the maintenance of parallelism between the lower 5 and upper 4 plates, during the lowering and raising movements of the lower plate 5 serving as a support base for the vehicle 2 with the upper plate 5 fixed on a longitudinal side member on a side of the body of the vehicle 2.

La platine inférieure 5 reste sensiblement parallèle à la platine supérieure servant de fixation solidaire de la caisse du véhicule 2, notamment du châssis du véhicule 2, pendant son déploiement. The lower plate 5 remains substantially parallel to the upper plate serving as a solid attachment to the body of the vehicle 2, in particular to the chassis of the vehicle 2, during its deployment.

Un entrainement du moteur réversible 25 dans un deuxième sens opposé au premier sens entraine l ’ éloignement relatif des deux extrémités supérieures 21 , 22, qui sont entraînées vers des extrémités opposées 24 de la vis sans fin 23 , ce qui replie les bielles 8,9, 10, 1 1 et rapproche la platine inférieure 5 vers la platine supérieure 4 et replie le système 1 sensiblement parallèlement à l ’ axe Z vers sa forme repliée. A drive of the reversible motor 25 in a second direction opposite to the first direction causes the relative separation of the two upper ends 21, 22, which are driven towards opposite ends 24 of the worm screw 23, which folds the connecting rods 8, 9, 10, 11 and brings the lower plate 5 closer to the upper plate 4 and folds the system 1 substantially parallel to the Z axis towards its folded shape.

Cette forme repliée est illustrée par la Figure 4, dans laquelle les bielles 7,8,9, 10, 1 1 , liées par des liaisons pivot 16, 17, 18, 19, 20 et placées deux à deux en quinconces les unes par rapport aux autres, sont repliées à leur maximum sensiblement parallèlement à l ’ axe longitudinal X pour être contenues dans la trappe d’ accès verrouillable 3. This folded shape is illustrated by Figure 4, in which the connecting rods 7, 8, 9, 10, 11, linked by pivot links 16, 17, 18, 19, 20 and placed two by two in staggered rows relative to each other, are folded to their maximum substantially parallel to the longitudinal axis X to be contained in the lockable access hatch 3.

Le système 1 est notamment par exemple adapté pour tenir dans un parallélépipède de l ’ ordre de six cents millimètres par cent millimètres par cent millimètres à l ’ état replié, ce qui permet d’ atteindre un encombrement particulièrement faible. System 1 is for example adapted to fit into a parallelepiped of the order of six hundred millimeters by one hundred millimeters by one hundred millimeters when folded, which allows for a particularly small footprint.

Le système 1 est notamment par exemple adapté pour tenir dans un parallélépipède de l ’ ordre de cinq cent soixante-dix millimètres par quatre-vingt- quatorze millimètres par quatre-vingt-deux millimètres à l ’ état replié, ce qui permet d’ atteindre un encombrement particulièrement faible. The system 1 is, for example, adapted to fit into a parallelepiped of the order of five hundred and seventy millimeters by ninety-four millimeters by eighty-two millimeters in the folded state, which makes it possible to achieve a particularly small footprint.

La longueur de la platine inférieure est par exemple comprise entre cinq cent soixante-seize millimètres une dimension maximale de mille six cents millimètres, ce qui permet qu’une force comprise entre sept cent vingt kilos- Newtons et trois mille quatre cent quatre-vingt-dix kilos-Newtons exercée sur une roue levée en position de cric du système 1 ne permet pas de déstabiliser le véhicule 2. The length of the lower plate is for example between five hundred and seventy-six millimeters and a maximum dimension of one thousand six hundred millimeters, which allows a force of between seven hundred and twenty kilo-Newtons and three thousand four hundred and ninety kilo-Newtons exerted on a wheel raised in the jack position of the system 1 not to destabilize the vehicle 2.

Ces valeurs sont suffisamment importantes pour conclure que la sécurité en mode cric, avec une ou deux roues décollées du sol, est assurée. These values are significant enough to conclude that safety in jack mode, with one or two wheels off the ground, is ensured.

La platine de l ’ ensemble du système est fixe par rapport au châssis du véhicule donc aucun mouvement de rotation ou de ripage n’ est possible. The entire system's platform is fixed relative to the vehicle chassis, so no rotation or slipping movement is possible.

De plus, le dimensionnement de la base d’ appui interdit tout mouvement de celle-ci par rapport au châssis. In addition, the dimensioning of the support base prevents any movement of the latter relative to the chassis.

On peut ainsi imaginer que la voiture en positon cric sur le système 1 repose sur une poutre en répartissant sa charge sur une grande surface d’ appui . We can thus imagine that the car in jacked position on system 1 rests on a beam, distributing its load over a large support surface.

Cet aspect sécuritaire est un point que nuis autres crics ne peut revendiquer car la maj orité de ceux-ci ne repose que sur des points d’ appui ponctuels sur le châssi s du véhicule et une petite surface d’ appui au sol . This safety aspect is a point that no other jacks can claim because the majority of them only rely on specific support points on the vehicle chassis and a small support surface on the ground.

Il est souvent très difficile de les mettre correctement en place tant au niveau du châssis que de maintenir une position verticale correcte à la montée de celui-ci, sans compter les éléments extérieurs qui amènent le véhicule à bouger : passage d’un poids lourd, vent fort, etc ... It is often very difficult to put them in place correctly both at the chassis level and to maintain a correct vertical position when raising it, not to mention the external elements which cause the vehicle to move: passage of a heavy goods vehicle, strong wind, etc.

Dans un mode de réali sation, le système 1 est intégré à une caisse de véhicule, et est configuré pour le levage ou la stabilisation d’un premier flanc latéral d’un véhicule 2 sur lequel est montée ladite caisse. In one embodiment, the system 1 is integrated into a vehicle body, and is configured for lifting or stabilizing a first lateral flank of a vehicle 2 on which said body is mounted.

Ladite caisse peut comporter en outre un deuxième système 1 configuré pour le levage ou la stabilisation d’un deuxième flanc latéral du véhicule 2 s opposé au premier flanc latéral du véhicule 2 sur lequel est monté ladite caisse. Said body may further comprise a second system 1 configured for lifting or stabilizing a second lateral flank of the vehicle 2 opposite the first lateral flank of the vehicle 2 on which said body is mounted.

Ainsi, un utilisateur peut commander le levage ou la stabilisation de n’ importe lequel des deux flancs du véhicule 2 grâce au système 1. Thus, a user can control the lifting or stabilization of any of the two sides of the vehicle 2 using the system 1.

L’ invention concerne également un véhicule 2 qui comporte à la fois une telle caisse de véhicule et une trappe d’ accès verrouillable 3 configurée pour verrouiller ou déverrouiller un accès au système 1 et pour permettre son escamotage ou sa saillie dans ou hors du véhicule 2. The invention also relates to a vehicle 2 which comprises both such a vehicle body and a lockable access hatch 3 configured to to lock or unlock access to the system 1 and to allow its retraction or projection into or out of the vehicle 2.

Ainsi, le véhicule 2 qui comporte le système 1 peut prévoir de conditionner l ’utilisation dudit système 1 à des états d’ autre organes du véhicule 2, en autorisant ou non le déverrouillage dudit système 1. Thus, the vehicle 2 which includes the system 1 can provide for conditioning the use of said system 1 on states of other components of the vehicle 2, by authorizing or not the unlocking of said system 1.

Par exemple, un procédé de mise en œuvre du système dans le véhicule comporte les étapes suivantes : la vérification de l ’ extinction du véhicule 2, la mise en place d’une interdiction de démarrage du véhicule 2, le déverrouillage de la trappe d’ accès 3 sur un flanc du véhicule 2 via un système de commande du véhicule 2, par exemple un écran tactile d’un poste de conduite du véhicule 2, la saillie du système 1 hors du véhicule 2 à travers la trappe d’ accès 3 , l ’ activation du moteur réversible 25 dans un premier sens jusqu’ à un levage souhaité d’ au moins une roue du véhicule 2 ou jusqu’ à une stabilisation souhaitée du véhicule 2 par rapport au sol par l ’ écartement des platines inférieures et supérieures 4, 5. For example, a method of implementing the system in the vehicle comprises the following steps: checking that the vehicle 2 has been switched off, implementing a start-up ban on the vehicle 2, unlocking the access hatch 3 on a side of the vehicle 2 via a control system of the vehicle 2, for example a touch screen of a driver's station of the vehicle 2, protruding the system 1 out of the vehicle 2 through the access hatch 3, activating the reversible motor 25 in a first direction until a desired lifting of at least one wheel of the vehicle 2 or until a desired stabilization of the vehicle 2 relative to the ground by moving the lower and upper plates 4, 5 apart.

Ce procédé permet à l ’utilisateur le positionnement du système 1 dans une position de levage ou dans une position de stabilisateur en toute sécurité, puisqu’ aucun risque de démarrage ou de mise en mouvement non souhaités du véhicule 2 ne sont possibles. This method allows the user to position the system 1 in a lifting position or in a stabilizer position in complete safety, since there is no risk of unwanted starting or movement of the vehicle 2.

Ce procédé peut prévoir une étape de vérification de l ’ actionnement d’ au moins un système de freinage du véhicule 2, par exemple l ’ activation du frein à main. Le procédé peut comporter en outre les étapes suivantes : la vérification de l ’ extinction du véhicule 2, l ’ activation du moteur réversible 25 dans un deuxième sens opposé au premier sens jusqu’ à un abaissement souhaité du véhicule 2 par rapport au sol par le rapprochement des platines inférieures et supérieures 4, 5, l ’ escamotage du système 1 dans le véhicule 2 à travers la trappe d’ accès 3 , le verrouillage de la trappe d’ accès 3 via le système de commande du véhicule 2, la fin de l ’ interdiction de démarrage du véhicule 2. This method may provide a step of verifying the actuation of at least one braking system of the vehicle 2, for example the activation of the handbrake. The method may further comprise the following steps: verifying the extinction of the vehicle 2, activating the reversible motor 25 in a second direction opposite to the first direction until a desired lowering of the vehicle 2 relative to the ground by bringing together the lower and upper plates 4, 5, retracting the system 1 into the vehicle 2 through the access hatch 3, locking the access hatch 3 via the control system of the vehicle 2, ending the prohibition on starting the vehicle 2.

Ce procédé permet la rétractation sécurisée du système 1 dans la trappe d’ accès 3 à l ’issue de son utili sation, sans risque de démarrage du véhicule. This process allows the safe retraction of the system 1 into the access hatch 3 after its use, without the risk of starting the vehicle.

Ce procédé peut prévoir une étape de vérification de l ’ actionnement d’ au moins un système de freinage du véhicule 2, par exemple l ’ activation du frein à main. On peut aussi, grâce aux procédés précédents, empêcher le démarrage dangereux du véhicule 2 avec le système 1 déployé, ainsi que le déploiement dangereux du système 1 hors de la trappe d’ accès 3 pendant que le véhicule est démarré ou se déplace. This method may provide a step of verifying the actuation of at least one braking system of the vehicle 2, for example the activation of the handbrake. The above methods can also prevent dangerous starting of the vehicle 2 with the system 1 deployed, as well as dangerous deployment of the system 1 out of the access hatch 3 while the vehicle is started or moving.

Pour la fonction « stabilisateur », un couplage du système de commande avec un gyroscope du véhicule 2 peut être prévu de manière à pouvoir intégrer la prise en compte d’une orientation du véhicule 2 par rapport à un plan horizontal à la fonction de commande de déploiement du système 1 pour la stabilisation du véhicule 2. For the “stabilizer” function, a coupling of the control system with a gyroscope of the vehicle 2 can be provided so as to be able to integrate the taking into account of an orientation of the vehicle 2 relative to a horizontal plane into the deployment control function of the system 1 for the stabilization of the vehicle 2.

On peut par exemple prévoir de conditionner la possibilité de déploiement du système 1 en fonction d’un angle du véhicule 2, ou encore de régler individuellement la dureté de certains amortisseurs du véhicule 2 en fonction de l ’ inclinaison de celui-ci pour augmenter son horizontalité lorsqu’une commande de stabili sation par le système 1 est effectuée. For example, it is possible to provide for conditioning the possibility of deployment of the system 1 as a function of an angle of the vehicle 2, or to individually adjust the hardness of certain shock absorbers of the vehicle 2 as a function of the inclination of the latter to increase its horizontality when a stabilization command by the system 1 is carried out.

On réalise ainsi un système 1 intégrable à tout type de véhicule et un procédé pour sa mise en œuvre, permettant le levage d’ au moins une roue du véhicule 2, ou la stabilisation d’un flan du véhicule 2 qui intègre ledit système 1 , de manière motorisée et sécurisée, adapté pour maintenir un plan de manœuvre parallèle à l ’ axe longitudinale X du véhicule 2, contrairement aux crics connus dont le plan de manœuvre est perpendiculaire à l ’ axe longitudinale du véhicule 2, ce qui assure une plus grande sécurité de manœuvre et une mise en service par l ’utilisateur sans aucune action manuelle sur le système 1 , et ce pour une grande variété d’ inclinaisons de terrains. This produces a system 1 that can be integrated into any type of vehicle and a method for its implementation, allowing the lifting of at least one wheel of the vehicle 2, or the stabilization of a side of the vehicle 2 which integrates said system 1, in a motorized and secure manner, adapted to maintain a maneuvering plane parallel to the longitudinal axis X of the vehicle 2, unlike known jacks whose maneuvering plane is perpendicular to the longitudinal axis of the vehicle 2, which ensures greater safety of maneuver and commissioning by the user without any manual action on the system 1, and this for a wide variety of terrain inclinations.
