Description

1 Châssis-coque télescopique pour véhicules automobiles modulables. Un cadre métallique de support et de rigidité mécanique des véhicules automobiles dont le but est d'allonger et écourter les véhicules automobiles selon la nécessité. La croissance démographique des populations entraine la croissance du parc automobile planétaire ainsi que ses conséquences d'ordre économique et écologiques. Les parkings sont pleins, les voies publiques envahies. Les grands véhicules (5 portes) - du genre "monospace" ou " berlingot" - ont du mal à se garer par rapport aux petites (3 portes) - "citadines". Face à ce problème, certaines gens optent pour avoir ces deux types de véhicules et les utilisent selon les besoins. Quand au pouvoir public, il multiplie les parkings publics et envahit de plus en plus les voies publiques en défaveur des espaces verts environnementaux. Le nouveau type de véhicule à châssis-coque télescopique ainsi inventé permet de raccourcir le grand véhicule (5 portes) en petit (3 portes) pour des besoins de stationnement pendant les courses familiales (vacances, tourismes,...) ou des besoins des courses à caractère personnel et/ou professionnel. Ainsi, faisant "deux dans un", il a un impact de dimension économique et environnemental du fait qu'il concourt à la réduction du parc automobile et stationnement public en faveur de l'environnement, la pollution environnementale est revue à la baisse (déchets chimiques, électroniques et autres : vidange, batterie, éléments électroniques ...) ainsi que l'exploitation des ressources naturelles afférentes à la fabrication automobile. Ce véhicule à châssis-coque innovant à 4 portes latérales (Fig. l a) peut se raccourcir en 2 portes latérales (Fig.lb) et vice-versa selon le besoin. Le châssis-coque innovant est composé d'un double cadre métallique télescopique (Fig.2a, Fig.2b) sur lequel se fixent tous les éléments de la carrosserie télescopique (Fig.la, Fig.1b). La partie avant de ce cadre métallique (Fig.2a), appelée" cadre femelle", est fixe. La partie arrière (Fig.2b), "appelée cadre mâle", est mobile. La base de ce cadre métallique innovant est composée des deux longerons longitudinaux télescopiques (Fig.la :1, Fig.1b : 2) (deux poutres télescopiques) avec des traverses de renfort tubulaires latéraux (entretoises) (Fig.3a :22) qui consolident sa rigidité face aux sollicitations des éléments d'assemblement internes, les latéraux périphériques aux longerons (Fig.3a :13) et les soubassements mécaniques de tenue de route ou de propulsion (Fig.3a :23,24). Un cadre tubulaire parallélépipédique télescopique (Fig.1a :3) surmontant la base télescopique qui fait la charpente de la carrosserie. Elle est renforcée à son tour par des traverses verticales (Fig.1 a :10) et horizontales (Fig.2a :29, Fig.3a :29, Fig.2b :17, Fig.3a :17) ainsi que des équerres (Fig.la :8, Fig.2a :9) pour assurer la rigidité mécanique du châssis-coque télescopique afin de résister aux impacts latéraux et longitudinaux. Il a deux supports coulissants (Fig. l a :8, Fig.3a :8 ) pour la modulation par encastrement du cadre "mâle" (Fig.3a :5). Le cadre parallélépipédique et sa base sont tous intégrés dans la carrosserie télescopique du véhicule faisant ainsi un mono bloque télescopique lequel supporte et rigidifie tous les éléments constituant d'un véhicule qui s'y attache directement ou indirectement. Au milieu de la partie avant du cadre "femelle' est fixée une boite de transmission (Fig.3a :25, Fig.lc :25) renfermant une chaine d'engrenages (Fig.lc :16a, 16b, 37, 26) relayer par deux chaines de transmission (Fig.lc :27,28). Le mécanisme de transmission du mouvement rotatif provenant du moteur se branche à cet en grenage (Fig.1 c :15,14) pour actionner la modulation du châssis-coque (véhicule) télescopique. En option, cette boite d'engrenage (Fig.1 c :25) peut être remplacé par un dispositif pneumatique (compresseur) pour accomplir la même tâche. Les organes rigides longitudinaux du véhicules asservis à la modulation du châssis-50 coque tels que le tuyau d'échappement (Fig.3a :23), l'arbre de transmission (Fig.3a :24) et autres sont aussi télescopiques (Fig.3b, Fig.3c, Fig.3d). Les uns, pour transmettre les 2952894 -2- mouvements mécaniques (Fig.3c), avec une partie "femelle" (Fig.3c :24c) et "mâle "(Fig.3c :24b), les éléments internes coulissant sont en forme de croix (Fig.3c :24a, Fig.3e, Fig.3f). Les autres, bien étanches, pour le passage des fluides liquides ou gazeux (Fig.3 :b) tels que les gaz de combustion, les huiles, etc. Les organes flexibles sont aussi 5 télescopiques. En forme spirale, ils enroulent leurs supports télescopiques aux quels leurs bouts sont attachés pour s'allonger et se compresser au rythme des mouvements du châssis-coque télescopique (Fig.3 :d). Devant et derrière la base sont montés des pare-chocs à compression (Fig. l a :19,20, Fig.3a : 19, 20), un dispositif de sécurité contre les chocs frontaux et arrières, utilisant des 10 ressorts ou autres systèmes à pression pour dissiper l'énergie cinétique de translation. Ce châssis-coque innovant fonctionne en mode "raccourci" (véhicule 3 portes) et en mode normal appelé "rallongé" (véhicule 5 portes). Au départ, le véhicule (5 portes) roule comme normalement pour faire les courses en famille (vacances, tourismes, ...). En cas de souci de parking ou en cas de besoins de faire des courses personnelles ou 15 professionnelles, tous les passagers descendent du véhicule, le moteur est mis au point mort. Le conducteur actionne le levier (Fig.la :12, Fig.lc :12,Fig.3c :12) en l'étirant puis le ramenant vers lui pour le bloquer (Fig.1c :12, Fig.3c :12), une commande électrique automatique baisse les vitres arrières, l'organe de transmission par contact solide (Fig.lc :15) avance jusqu'à la jonction avec l'engrenage (Fig.lc :14, Fig.3c :14) du 20 mécanisme de transmission des mouvements rotatifs (Fig. l c :25) du châssis-coque. Puis il engage la première vitesse et avance doucement jusqu'à ce que la petite poutre (Fig.la :2, Fig. l b :2, Fig.lc :2) qui tracte la partie arrière "cadre mâle" arrive à l'accouplement complet (Fig.1 c :30) et enclenche le verrouillage mécanique de sécurité (Fig.lc :39). Passant par l'espace (Fig.2a :33), le cadre "mâle" s'emboite convenablement dans le 25 cadre " femelle ", les 2 portières latérales arrières (Fig.la :6) s'encastrent dans les creux des portières latérales avant (Fig.la :7,Fig.lb :7). Les portes latérales avant s'ouvrent comme normalement mais les unes dans les autres. La partie basse du siège arrière (Fig.1 a :11) attachée à au cadre "femelle" par 2 supports rigides (Fig.la :36, Fig.3a :36), s'encastre sous le coffre arrière quand le cadre 30 "mâle" s'avance. La partie basse ressort à l'opération inverse. Le conducteur désactive le levier (Fig.lc :12) qui rentre à sa position initiale par l'action du ressort de rappel (Fig.lc : 38 ), l'élément de transmission de mouvement par contact (Fig.lc :15 ) décroche et retourne à sa position initiale. Le conducteur peut maintenant rouler et garer en mode "raccourci " (3 portes) (Fig.lb). Le mode "rallongé" est naturellement l'opération 35 inverse du mode "raccourci". L'activation du mécanisme de transmission du mouvement rotatif provenant du moteur (Fig. l a :31) pour entrainer le cadre "mâle" dépend des possibilités offertes par les différents types de véhicules. L'invention est destinée à tous les constructeurs des véhicules automobiles avec libre choix de traction. L'ossature est totalement tubulaire, hormis sa base qui l'est partiellement ; la forme 40 aérodynamique est prononcée afin de rendre le véhicule léger et réduire la consommation moyenne d'énergie pendant le déplacement, Bien que la partie centrale soit assez robuste pour résister contre les flexions, les torsions et les vibrations, les poids sont répartis de façon à moins solliciter le milieu par rapport aux essieux.1 Telescopic chassis for modular motor vehicles. A metal frame of support and mechanical rigidity of motor vehicles whose purpose is to lengthen and shorten motor vehicles as needed. The demographic growth of the populations leads to the growth of the global automobile fleet as well as its economic and ecological consequences. Parking lots are full, public roads invaded. Large vehicles (5 doors) - like "minivan" or "berlingot" - have trouble parking compared to small (3 doors) - "city". Faced with this problem, some people choose to have both types of vehicles and use them as needed. When the public power, it multiplies the public car parks and invades more and more the public roads in disfavor of environmental green spaces. The new type of vehicle with telescopic hull thus invented makes it possible to shorten the large vehicle (5 doors) in small (3 doors) for parking needs during family races (holidays, tourism, ...) or the needs of personal and / or professional races. Thus, making "two in one", it has an impact of economic and environmental dimension because it contributes to the reduction of the car park and public parking for the environment, environmental pollution is revised downward (waste chemical, electronic and other: emptying, battery, electronic elements ...) as well as the exploitation of the natural resources related to the car manufacturing. This innovative 4-door hull-chassis vehicle (Fig. L a) can be shortened to 2 side doors (Fig.lb) and vice versa as needed. The innovative chassis-shell is composed of a double telescopic metal frame (Fig.2a, Fig.2b) on which all the elements of the telescopic body (Fig.la, Fig.1b) are fixed. The front part of this metal frame (Fig.2a), called "female frame", is fixed. The rear part (Fig.2b), called "male frame", is mobile. The base of this innovative metal frame consists of two longitudinal telescopic longitudinal beams (Fig.la: 1, Fig.1b: 2) (two telescopic beams) with lateral tubular reinforcing beams (spacers) (Fig.3a: 22) which consolidate its rigidity against the stresses of the internal assembly elements, the lateral peripheries to the longitudinal members (Fig.3a: 13) and the mechanical bases of road holding or propulsion (Fig.3a: 23,24). A telescopic parallelepipedal tubular frame (Fig.1a: 3) surmounting the telescopic base that forms the frame of the bodywork. It is reinforced in turn by vertical crosspieces (Fig.1 a: 10) and horizontal crosspieces (Fig.2a: 29, Fig.3a: 29, Fig.2b: 17, Fig.3a: 17) as well as brackets ( Fig.la: 8, Fig.2a: 9) to ensure the mechanical rigidity of the telescopic hull frame to resist lateral and longitudinal impacts. It has two sliding brackets (Fig. L a: 8, Fig.3a: 8) for recessed modulation of the "male" frame (Fig.3a: 5). The parallelepiped frame and its base are all integrated into the telescopic body of the vehicle thus making a mono telescopic block which supports and stiffens all the constituent elements of a vehicle that attaches directly or indirectly thereto. In the middle of the front part of the "female" frame is fixed a transmission box (Fig.3a: 25, Fig.lc: 25) enclosing a chain of gears (Fig.lc: 16a, 16b, 37, 26) relay by two chains of transmission (Fig.lc: 27,28) .The mechanism of transmission of the rotary movement coming from the engine is connected to this in graining (Fig.1 c: 15,14) to actuate the modulation of the chassis-shell ( telescopic vehicle) Optionally, this gearbox (Fig.1 c: 25) can be replaced by a pneumatic device (compressor) to accomplish the same task.The longitudinal rigid members of the vehicle servocontrolled to the chassis-50 modulation such as the exhaust pipe (Fig.3a: 23), the transmission shaft (Fig.3a: 24) and others are also telescopic (Fig.3b, Fig.3c, Fig.3d). to transmit the mechanical movements 2952894 -2- (Fig.3c), with a "female" (Fig.3c: 24c) and "male" (Fig.3c: 24b), the internal sliding elements are shaped cross (Fig.3c: 24a, Fig.3e, Fig.3f). The others, well sealed, for the passage of liquid or gaseous fluids (Fig.3: b) such as flue gases, oils, etc. The flexible members are also telescopic. In a spiral shape, they wrap their telescopic supports to which their ends are attached to lengthen and compress to the rhythm of the movements of the telescopic frame-shell (Fig.3: d). In front of and behind the base are compression bumpers (Fig. La: 19,20, Fig. 3a: 19, 20), a frontal and rear impact protection device, using springs or other pressure to dissipate the translational kinetic energy. This innovative chassis-shell works in "shortened" mode (3-door vehicle) and in normal mode called "extended" (5-door vehicle). Initially, the vehicle (5 doors) rolls as normally for shopping with family (holidays, tourism, ...). In case of parking concerns or in case of personal or professional shopping needs, all passengers get off the vehicle, the engine is put in neutral. The driver actuates the lever (Fig.la: 12, Fig.lc: 12, Fig.3c: 12) by stretching it and then bringing it back to block it (Fig.1c: 12, Fig.3c: 12), an automatic electric control lowers the rear windows, the solid contact transmission member (Fig.lc: 15) advances to the junction with the gear (Fig.lc: 14, Fig.3c: 14) of the mechanism transmission of rotary motions (Fig. lc: 25) of the hull frame. Then it engages the first gear and slowly advances until the small beam (Fig.la: 2, Fig. Lb: 2, Fig.lc: 2) which tows the rear part "male frame" arrives at the coupling complete (Fig.1 c: 30) and engages the mechanical safety lock (Fig.lc: 39). Passing through the space (Fig.2a: 33), the "male" frame fits properly in the "female" frame, the two rear side doors (Fig.la: 6) fit into the recesses of the doors front side (Fig.la: 7, Fig.lb: 7). The front side doors open as normally but in each other. The lower part of the rear seat (Fig.1 a: 11) attached to the frame "female" by 2 rigid supports (Fig.la: 36, Fig.3a: 36), fits under the trunk when the frame 30 "male" moves forward. The lower part comes out the opposite operation. The driver deactivates the lever (Fig.lc: 12) which returns to its initial position by the action of the return spring (Fig.lc: 38), the element of transmission of movement by contact (Fig.lc: 15) pick up and return to its original position. The driver can now drive and park in "shortcut" mode (3 doors) (Fig.lb). The "extended" mode is of course the inverse operation of the "shortened" mode. Activation of the mechanism for transmitting the rotary motion from the engine (Fig. 1a: 31) to drive the "male" frame depends on the possibilities offered by the different types of vehicles. The invention is intended for all manufacturers of motor vehicles with free choice of traction. The frame is totally tubular, except its base which is partially tubular; the aerodynamic shape 40 is pronounced to make the vehicle light and reduce the average energy consumption during the movement, Although the central portion is strong enough to withstand bending, twisting and vibration, the weights are distributed less stress on the medium compared to the axles.

45 En plus du pare-choc de sécurité innovant et du bon équilibrage (essieux, pont arrière et les jonctions mobiles) , la forme cavitaire des poutres (Fig.la :40) offre la possibilité d'avoir un centre de gravité assez bas pour la tenue de la route et une bonne suspension pour garantir la sureté du véhicule. Dorénavant, on peut confortablement passer d'un véhicule automobile "5 portes" à "3 portes" et vice-versa, en cas d'une nécessité. Et réduire le parc automobile planétaire. 45 In addition to the innovative safety bumper and good balancing (axles, rear axle and movable junctions), the cavity shape of the beams (Fig.la: 40) offers the possibility of having a center of gravity low enough for road holding and good suspension to ensure the safety of the vehicle. From now on, one can comfortably pass from a motor vehicle "5 doors" to "3 doors" and vice versa, in case of necessity. And reduce the global car fleet.
