Definitions

  • the invention concerns a device for vehicles, comprising a metallic frame which forms the supporting part for a body composed of large body units of plastic, preferably thermoplastic and especially coloured thermoplastic, wherein the frame comprises pillars projecting upwardly from a base structure to support the vehicle's body and possibly also roof/side beams.
  • the invention also concerns a method for manufacturing a vehicle of this kind.
  • profiles e.g. in aluminium
  • space frames These frames are built up by joining the profiles together by means of welding, gluing or by other mechanical attachment means.
  • Such a frame e.g. in aluminium, is light in weight and can be calculated and dimensioned to provide a very high level of safety.
  • panels and body parts In order to be able to construct a final vehicle, panels and body parts have to continue to be built together on this frame.
  • metal possibly aluminium panels or plastic panels may be used which are mounted on the frame by substantially known means.
  • Supporting frames of this kind can also relatively simply be built in a steel structure where a simple surface treatment then has to be carried out for corrosion protection. This treatment is substantially simplified compared to surface treatment of a traditional car body, which subsequently has to be sprayed.
  • Space frames is a term for frames of this kind which are composed of profiles with connection points. These are employed in several types of vehicle and are of considerable interest. A major challenge, however, is to be able to achieve a simplified and rational installation of body parts and panels. It is known in the prior art to use plastic in body parts in various design variants in combination with an aluminium frame or steel frame. Polyester or epoxy body parts have been most used, but other types of plastic have also been employed, by means of vacuum forming, injection moulding or where panels are produced by means of spraying and fitting.
  • EP Patent 485457 and 697974 methods are described as to how a metal frame can be used in combination with large body parts which in a simple design can form the whole body.
  • the object of the present invention is to provide a new form of assembly for a vehicle, where the vehicle body can be manufactured from large plastic units, preferably thermoplastic and specially preferred coloured thermoplastic, where the body parts can also be made in smaller production series and where these can be mounted in a simple and rapid manner on a vehicle frame structure, e.g. of aluminium, without the use of complicated aids.
  • the invention also comprises a method for manufacturing a vehicle of this kind, which method is characterized by the features presented in patent claim 13.
  • the invention differs from the previously known designs, representing a highly simplified design.
  • the problems with the previously known designs are that it is a long-winded and difficult process to mount solid cast bodies or large parts of the body, since these are difficult to integrate and mount in a prefabricated framed structure.
  • the design according to DE 19500361 requires welded-on and integrated metal plates in the framed structure, since the body panels only give the vehicle the external shape and appearance without a closely connected body module.
  • the wish is to unite style and external appearance to a greater extent with utility and functional solutions by a combination of a metal frame and plastic panels. This is done in a manner whereby the plastic body part has more integrated functions than simply being a cover with exterior and visual advantages.
  • the plastic body parts include functions such as sealing and separation of the vehicle's interior and exterior environment, and the parts may include elements such as wheel arches, mudguards, etc., inset lights, sealing edges, etc.
  • a special feature of the invention is also that moulding methods and materials can be used for production of the body parts which eliminate the need for painting of the body parts. Painting is an undesirable operation on account of environmental conditions and costs.
  • front and rear vehicle body parts are designed to overlap, resulting in a reinforced central part in the vehicle. This provides a further reinforcement and separation between the external and internal environments, which can be advantageous in special applications.
  • figure 1 is a completely schematic view illustrating the design of the device according to the invention, with the parts separated from one another.
  • figure 2 is a second embodiment of the invention, viewed in a schematic horizontal section
  • figure 3 is an embodiment corresponding to figure 2 in a lateral sectional view, in connection with a cabriolet design
  • figure 4 is a side view of the cabriolet design in figure 3.
  • Figure 1 illustrates the principle of the device according to the invention, some of the body parts having been pulled out to the side, while the final assembled shape is illustrated by means of broken lines.
  • the basic element in the design is a metallic frame, e.g. a frame of the "space frame” type, which is designated 1 and on which the necessary mechanical components and systems are mounted in a simple and rational manner.
  • the frame is open with easy access.
  • the vehicle can therefore be constructed with chassis systems in the front and rear, an engine and other technical connections without any hindrance from closed areas in the frame.
  • the floor system 2 can be made flexible, thus making room for these said transmission systems under the vehicle, e.g. in the area designated 3.
  • the floor system is designated 2.
  • a floor 2 can therefore be attached to the frame, e.g. on two levels in order to provide space and opportunity for mounting batteries under the vehicle in the area at 3. In a design of this kind attempts will be made to lay the high floor level under the seats 4.
  • the vehicle's upwardly projecting pillars which are designated A and B pillars, and given the reference numerals 5 and 6, are also mounted on the frame, together with a roof frame 7 for closed vehicles.
  • the upwardly projecting pillars are preferably approximately vertically arranged, but may also assume angled or curved shapes, according to the body design.
  • the body is mainly composed of a rear part 8, which constitutes a large body part comprising both the rear sides, wheel arches and mudguards and floor section which is then attached to the vehicle's B pillars 6, possibly also other points. In cases where the vehicle has 4 doors, this part 8 may be attached to the vehicle's so-called C pillars, and the B pillar thereby becomes a middle pillar.
  • the front part 9 of the vehicle is designed as a cover which is open below, thus enabling it to be laid over the engine and wheels and attached in the area around the vehicle's A pillars 5.
  • This cover 12 may also be an extended part of the plate in the floor.
  • a loose roof 10 may be attached to the frame over the window, and doors installed on the A and B pillars 5 and 6 respectively, possibly by using 3 pillars on each side, between the pillars.
  • FIGS 2-4 there is illustrated a second embodiment of the invention, where the rear and front parts 8 and 9 overlap each other.
  • the rear body part 8 is thereby designed with the external form and the external measurements required by the vehicle up to the area at the rear pillar or the B pillar 6, while the vehicle's front body part 9 extends backwards with the external dimensions and design of the vehicle in the area up to the A pillars 5.
  • the front part of the rear body part 8 is extended forwards on the inside of the pillars 5 and 6, to the front area of the cabin's interior, where it forms an upwardly projecting or extending wall 1 1 between the cabin's internal compartment and the external technical compartment or motor compartment, where it can be terminated with an attachment or a seal against the lower window frame 13.
  • this part may include the vehicle's dashboard or the basic part of the dashboard 12, as illustrated in figure 3.
  • a bumper cover can be moulded into the front part 9, together with other details such as a grille, a recess and securing means for lights, etc.
  • the doors are installed as a subsequent part of the assembly process and are attached on the front pillar 5 and locked in a closed state against the pillar 6.
  • An important feature of this design is that the split line between the door and rear body part can be adjusted in a simple manner by adjusting or shifting the hinge point for the door on the pillar 5.
  • the front part can then be adjusted towards a front door line, with the result that it is in perfect alignment with the door split.
  • FIG. 1 a device is illustrated for a vehicle with a roof structure.
  • Figure 4 illustrates that the same vehicle device can also be employed with a design without a roof.
  • the invention represents a highly rational and effective method of constructing a vehicle.
  • the body parts, both front and rear, i.e. 9 and 8 are mounted after all the mechanical components, chassis, springs, engine, etc. have been installed on the open frame.
  • These can be made of different types of plastic by means of different production methods which offer the possibility of constructing three-dimensional large parts.
  • An example of such a part is a rotationally moulded part and vacuum forming and blowing may also be employed in the case of given design criteria.
  • a preferred material is thermoplastic and particularly coloured thermoplastic, but other plastic materials with similar properties may also be used.
  • the assembly of the plastic body parts and the metal structure offer the possibility of providing a good seal since there are no more body panels which have to be joined together and sealed.
  • the plastic edges may be pushed in and locked to the metal structure, e.g. by means of clamping.
  • these relatively large body parts do not provide any structural strength in the structure, they have an obvious functional effect in arriving at a complete vehicle.
  • the invention is described in purely schematic terms and the fact is referred to, e.g., that 3 pillars may also be used on each side instead of 2.
  • the device can be varied in many ways within the framework of the claims while retaining the main features, viz. the use of a large construction part as the front part and a large construction part as the rear part, these construction parts being in three-dimensional form, which gives them great strength and rigidity, thereby providing a safe body. It will be possible to vary the actual design and form.
