Abstract

The metallic inlays are formed as a grid of uninsulated live rails (e.g. 10) with coupling pieces comprising threaded bolts (17) and plug sockets. The bolt connections are designed as rapid action connections particularly connecting sockets. The flexible cables (15) located outside the floor section (1) are connected to the conducting rail (10) in the floor section via a clamping piece (18) and a nut (12) which is screwed onto the bolt connection (17). The floor section comprises a rigid plastic foam core (14) covered by a flass fibre reinforced outer layer (11). This foam core is divided into three sections by vertical extensions, the centre portion housing a control device and the two outer sections containing the storage batteries.

Description

Als selbsttragendes Bauelement ausgebildeter Kunststoff-Sandwich-Baukörper Kunststoffe setzen sich in immer weiteren Gebieten des Fahrzeugbaues durch. Ihre Verwendung ist nicht mehr auf nichttragende Karosserieteile beschränkt, sondern umfaßt auch kräftetragende Teile des Fahrzeugs, z.B. die Bodengruppe. Dieses großflächige und geometrisch oft recht kompliziert gestaltete Gebilde wird auch als kunststoff-Sandwich-Beuteil mit einem Hartschaumkern hergestellt, dessen Deckschichten z.8. aus mit Kunstharz getränkten Geweben bestehen können. Plastic sandwich structure designed as a self-supporting component Plastics are gaining acceptance in more and more areas of vehicle construction. Her Use is no longer limited to non-load-bearing body parts, but also includes force-bearing parts of the vehicle, e.g. the floor pan. This large area and geometrically often quite complicated structures are also called plastic sandwich bags with made of a rigid foam core, the top layers of which z.8. can consist of fabrics soaked with synthetic resin.

Es ist bekannt, Befestigungselemente wie Rohre oder Leisten u.a. für den späteren Zusammenbau des Fahrzeugs -erforderliche Verbindungsteile sowie zur Verstärkung dienende Einlagen mit in die Form einzubauen, so daß sie beim fertigen Bauteil im Schaumstoff und in den Deckschichten fest verankert sind (CH-PS 211 577).It is known to use fasteners such as pipes or strips, among others, for the later assembly of the vehicle -necessary connecting parts as well as for Reinforcement inserts are to be built into the mold so that they can be used when finished Component is firmly anchored in the foam and in the cover layers (CH-PS 211 577).

In der Praxis führt das dazu, daß es ohne erhebliche Rustzeiten nicht mehr möglich ist, eine z.B. zur Erstellung einer Sandwich-Bodengruppe bestimmte Schäumform in der erforderlichen Weise mit der notwendigen Anzahl fest zu verankernder Verbindungselemente vorzubereiten. Auch für die Befestigung der Leitungssysteme für die Energieträger, die bisher als Rohrleitungen oder auch als Kabel für die Weiterleitung des elektrischen Stromes ausgebildet sein können, müssen zahlreiche Verankerungen in den relativ dünnwandigen Deckschichten der Sandwich-Bodengruppe angebracht werden.In practice, this means that it does not work without considerable rust times more is possible, e.g. one intended to create a sandwich floor assembly Foam mold to be firmly anchored in the required manner with the necessary number Prepare fasteners. Also for fastening the pipe systems for the energy sources that were previously used as pipelines or as cables for the Forwarding of the electric current can be designed, must be numerous Anchoring in the relatively thin-walled cover layers of the sandwich floor assembly be attached.

Durch diese umständlichen Vorbereitungsarbeiten werden die teuren Schäumformen vor Beginn einer Jeden Ausschäumung eine unverhältnismäßig lange Zeitspanne hindurch belegt, was sich vor allem bei der Serienfertigung nachteilig auswirkt Die Vielzahl der einzeln im Sandwich-Bauteil zu verankernden metalliSchen glieder beeinflußt aber nicht nur die RüstbzW* Fertigungszeiten in ungünstiger Weise sondern kann auch die Steifigkeit und Widerstandsfähigkeit der Sandwich-Bodengruppe Deeinträchtigen.This cumbersome preparatory work becomes the expensive Foam molds a disproportionately long period of time before the start of each foaming proves through it, which is particularly disadvantageous in series production The multitude of individual metallic links to be anchored in the sandwich component but not only influences the set-up and production times in an unfavorable way, but also can also affect the rigidity and resilience of the sandwich floor pan.

Es sind bei Kunststoff-Sandwich-Bedengruppen und bei Kunststoff-Sandwich-Aufbsuten für Fahrzeuge zwar schon Verfahren bekannt, bei welchen mittels Einschäumens von Rohren und nachträglichem Einziehen von Drähten elektrische Verbindungen hergestellt werden. Dies ist jedoch z.B. bei Elektrofahrzeugen wegen der dort oft notwendigen großen Leiterquerschnitte und infolge der meist komplizierten Leitungsführungen nur schwer durchführbar.There are plastic sandwich panels and plastic sandwich tops for vehicles already procedure known which means Foaming of pipes and subsequent pulling in of wires electrical connections getting produced. However, this is often the case with electric vehicles because of the there necessary large conductor cross-sections and as a result of the mostly complicated cable routing difficult to implement.

Die Erfindung bezweckt eine Verbesserung der bekannten Kunststoff-Sandwich-Baukörper mit metallischen Einlagen.The invention aims to improve the known plastic sandwich structures with metallic inlays.

Im besonderen ist es Aufgabe der Erfindung, eine Kunststoff-Sandwich-Bodengruppe vorzuschlagen, die für die Serienfertigung geeignet ist, bei der also vor allem die für die Vorbereitung der Schäumform erforderlichen Rüstzeiten kurz sind und bei deren Verwendung ferner eine möglichst große. Anzahl von bei der weiteren Montage des Fahrzeugs notwendigen Arbeiten vorweggenommen bzw. überflüssig gemacht wird.In particular, it is the object of the invention to provide a plastic sandwich floor assembly to propose the one that is suitable for series production, that is, especially when it comes to the set-up times required for preparing the foam mold are short and if they are used, it is also as large as possible. Number of for further assembly work necessary for the vehicle is anticipated or made superfluous.

Eine Lösung der Erfindungsaufgabe ist darin zu sehen, daß die Einlagen ein zusammenhängendes, dreidimensionales, eigensteifes Gitter bilden, welches als Leiter für den Energiefluß dient.A solution to the problem of the invention is to be seen in the fact that the deposits form a coherent, three-dimensional, inherently rigid grid, which is called Head for the flow of energy is used.

Hierdurch wird der Zeitaufwand zur Vorbereitung der Schäumform für das Einschäumen erheblich gemindert, weil für die zu verlegenden Leitungen für den Energief-luß nur noch ein einziges zusammenhängendes Gitter gegenüber der Schäumform auszurichten und festzulegen ist. Ferner bringt es den Vorteil, daß vor Beginn der weiteren Montage die Hauptstränge der Kraftleitung oder -leitungen bereits fertig verlegt sind, also weder weiteren Arbeitsaufwand, noch zusätzlichen Raum beanspruchen.This reduces the time required to prepare the foaming mold for foaming is significantly reduced because for the lines to be laid for the Energy flow only a single coherent grid opposite the foam mold is to be aligned and determined. It also has the advantage that before the start of the further assembly, the main strands of the power line or lines are already finished are laid, so they do not take up any additional work or space.

Nach einer vorteilhaften Einzelheit der Erfindung können ferner Endstücke des eingeschäumten Gitters die Oberfläche des sanwich-Barukörpers durchdringen. Sie gestatten auf diese Weise ohne Nacharbeit den Anschluß der Kraftleitungen an die Energiequellen und an die Energieverbraucher.According to an advantageous detail of the invention, end pieces of the foamed-in lattice the surface of the sanwich baru body penetrate. In this way, they allow the power lines to be connected without reworking to the energy sources and to the energy consumers.
