Electric vehicle with a basic structure.

Technical area the available invention describes an electric vehicle with one-basic structure and a Aufnahmeraum.

running along a longitudinal axis of the electric vehicle State of the art [of 0002] electric vehicles your energy from energy stores, for example accumulators and/or Energiewandlern, for example gas cells refer and today according to standard are usually used. The energy sources must be loaded in the case of the energy stores again and the Energiewandler in the case of the gas cell supplied with fuels werden.

Users of electric vehicles are interested particularly in the fact that the energy sources are not already destroyed in easy accidents. Beyond that above all the prevention of withdrawing poisonous substances from the energy sources, the avoidance of short-circuits, becomes as well as of explosions, which can occur in damages of gas cells due to inflammation of gases, angestrebt.

In order to protect and shift the emphasis of the electric vehicle toward the lane the energy source within the electric vehicle as well as possible, the energy sources are placed if possible in the lower part of the body and outside of the crunch zone positioniert.

US the patent US 6,315,069 reveals an electric vehicle with one about central underneath the electric vehicle lying energy source, which by a Unterboden is enclosed, whereby the Unterboden is arranged underneath an interior ground on which a passenger space, is placed. The energy source is within a trough-shaped transmitting room, which lies approximately centered along a longitudinal axis of the electric vehicle, angeordnet.

By the kind of the storage of the energy source and the change of the body organization made in addition, the stability of the body is impaired, although the emphasis of the electric vehicle shifts downward toward lane ist.

The arrangement of the energy source in approximately central and along the longitudinal axis is of advantage in principle in the case of an impact of an accident vehicle from the side in approximately perpendicular to the longitudinal axis, but apart from making possible of small battery volumes, that above all air resistance is problematic by the large cross-section area of the arrangement and disadvantageful. In principle the danger exists with a confinement of the energy source with a collision that the energy source damages squeezed together by the side panels of the transmitting room and wird.

An advancement reveals the FR2 687,352. An electric vehicle with central along the longitudinal axis of the electric vehicle a stored energy source is described. The energy source is stored above an interior ground of the electric vehicle in a transmitting room, which is arranged projecting into the adjacent passenger space. The transmitting room forms to a certain extent a center console within the electric vehicle. By this arrangement the energy source is well in accidents protected and by the avoidance of an interference into the self-supporting body is attainable a sufficiently high rigidity and thus a small flexible deformation when driving and with a Seitenaufprall. The storage of the energy source projecting into the passenger space, takes however place away within the electric vehicle, whereby available space and thus the comfort for passengers is reduced and the baggage compartment is reduced. Apart from the smaller space offer, the emphasis lain more highly affects itself negatively. The arrangement revealed here causes also a replacing of the energy sources within the Fahrgastzelle.

Representation of the invention the available invention has itself to create placed to the task an electric vehicle with a transmitting room for an energy source, which protects the energy source before damages with a Seitenaufprall and which a fast and simple Anund uncoupling an energy source erlaubt.

A further task of the available invention can be attained it construction dependently by the transmitting room an improved rigidity of the self-supporting body, whereby available space in the passenger space and/or the loading area does not reduce and the size of the baggage compartment werden.

Beyond that aerodynamic advantages become due to as small a vehicle cross section as possible ausgenutzt.

Description an electric vehicle according to invention 1 extends from a rear end of 10 to a front end 11 toward a longitudinal axis L and by a basic structure 2, exhibiting a passenger space and/or loading area 24, is formed. When kind of a basic structure 2 knows a framework, a Spaceframe, which is called skeleton body, a Monococ or a self-supporting body to be used. For weight reduction training of a basic structure is particularly 2 for electric vehicles 1 vorteilhaft.

The basic structure 2 exhibits a body underbody, which covers an interior ground 20, on which the passenger space and/or loading area 24 and Interieur 25, for example seats 25 and instrument panels, the electric vehicle 1 applicably arranged sind.

The interior ground 20 of the basic structure 2 defines one level E of the basic structure 2, above which the passenger space 24 stores the Interieur 25. The interior ground 20 takes all torsion, bend, Zugund of thrust forces, which arise while driving or to a collision with an obstacle auf.

together with the basic structure 2 For the enterprise of the electric vehicle 1 an energy source 7 is intended, which is storable in a transmitting room 22. As energy source 7 an energy storage, for example an accumulator and/or a Energiewandler, is offered for example a gas cell an.

The transmitting room 22 is at least approximately centrically in-formed along the longitudinal axis L below the level E running into the interior ground 20. The transmitting room 22 is formed by a channel 220, which of the level E is out-arranged downward keel-like toward lane 6 away-rising up as part of the basic structure 2. By the arrangement of the interior ground 20 with the channel 220 the rigidity and the natural oscillation frequency of the interior ground 20 and thus that-basic structure 2 are strengthened, as the cross section of the interior ground 20 by the channel 220 is increased. The flexible deformation of the interior ground 20 becomes by this intensifying building method while driving and particularly with a collision of the electric vehicle 1 with an obstacle vermindert.

For the protection of the interior ground 20, which toward lane 6 points, a Unterboden 21 is intended as option, which the interior ground 20 totally or partly enclosing below the level E positioned solvable or inseparably fastened can be arranged. The Unterboden 21 runs preferentially at least approximately parallel to the level E of the interior ground 20 and takes also the channel off 220 toward lane 6 completely. The area 210, to which between interior ground 20 and Unterboden 21 remains can as back-up vacate or for the admission of functional parts to serve. Apart from the characteristic as spraying protection and cover of the interior ground 20, the Unterboden 21 causes a further reinforcement of the basic structure 2.

The channel 220 can do 20 of the rear end 10 up to the front end 11 along the entire length of the interior ground rising up, as in Fig. 3 shown, or the interior ground 20 only partly spanning formed out its. The channel 220 exhibits at least one channel wall 221 and takes up at least one energy source 7 to the transmitting room 22. The cross-section area of the channel 220 can be polygonal and/or rounded out-arranged, whereby only a rectangular cross-section area is represented in the lying close figures. The energy source 7 can directly let in into the channel 220 and there solvable fastened stored sein.

From the outside to be brought for the storage of the energy source 7 it is the energy source 7 directly into the channel 220 planned the transmitting room 22 of the rear end of 10 of the electric vehicle 1 to be made accessible and. The channel 220 can be lockably out-arranged at the rear end 10 with a flap or a cover, as in Fig.

suggested. The energy source 7 must with would bring in so far into the channel 220 to be brought that supply lines are connectable such as Elektroanschlüsse, control ports or climatic connections between the energy source 7 and appropriate connections of the electric vehicle 1. If means are intended for the cooling of the energy source 7, it must be ensured that these means are cash likewise in the form of cooling connections within the channel 220 anschliessCH699569A2. Within the channel 220 221 castors or rails 224 can be arranged along the channel walls, which for the Beund unloading 7 into the transmitting room 22 serves the energy source. At the energy source 7 equivalent castors 70 or rails appropriate in addition can, like in Fig. 4b to be represented, attached, whereby the energy source 7 through the channel 220 would drive relieved wird.

In addition, it is possible the fact that the energy source is 7, in an energy source carrier 8 solvable or inseparably fixable and is brought the energy source carrier 8 into the channel 220 and there is solvable fastened, whereby the power supplies must be contacted also here accordingly. In Fig. 4b is represented a drawer-like energy source carrier 8, which with rails 224, along the channel wall 221 arranged, zusammenwirkt.

In a further execution form the energy source carrier 8 is trogförmig trained and within the transmitting room 22 lowerable arranged firmly connected with the channel 220. Fig. 6 shows such a trogförmigen energy source carrier 8, which to a shears construction 9 is fastened, fixed to which is firmly with the channel 220 within the transmitting room 22 and is by hand lowerable by electric motors or over a spindle screw 91. When using a trogförmigen and lowerable energy source carrier 8 the channel 220 must be equipped with a movable floor space and remove accordingly the Unterboden 21 before the Beund unloading. This floor space can be hinged or finear parallel to the longitudinal axis L adjustably implemented, so that the transmitting room 22 is accessible after manipulation of the floor space and the shears construction fastened within the channel 220 is out lowerable 9 including energy source carrier 8 from the channel 220. Into the lowered energy source carrier 8 an energy source 7 can be brought and fixed and be loaded by means of shears construction 9 into the transmitting room 22. After the loading with the energy source 7 the channel 220 is closed and the Unterboden 21 can the interior ground 20 enclosing installed werden.

To the weight savings it is to be planned favourably in a garage a shears construction outside of the electric vehicle, with which the energy source is removable 7 from the channel 220. With this execution form the energy source carrier 8 with the help of the independent shears construction out of the channel 220 can be taken downward, whereby the electric vehicle 1 no additional weight would ride along must. The electric vehicle 1 is positioned with the channel 220 for replacing the energy source 7 over a mentioned shears construction in the brought in condition. Subsequently, the shears construction is driven out toward the interior ground 20, so that the energy source carrier 8 including energy source 7 is taken out of the channel kann.

In place of the trogförmigen energy source carrier 8 is the use of brackets or arms, which keep the energy source 7 lowerable in the channel 220 fastened, möglich.

For the reinforcement of the channel 220 the arrangement of the channel walls 221 of the channel 220 running with a majority of Sicken 223 is in longitudinal direction of the channel 220 favourably. The Sicken 223 can be projecting into the channel 220 or outward arranged, whereby the Sicken 223 can be arranged also by welding creases. Depending upon local needs the Sicken 223 can crosswise or in longitudinal direction of the channel 220 running attached sein.

In place of the Sicken 223 also pipes know crosswise or in longitudinal direction of the channel 220 running the channel 220 strengthening attached sein.

Pointing in further execution forms a majority is keel-like, intended from sinkings 23 in the interior ground 20 outside of the range of the transmitting room 22 toward the lane 6. These additional sinkings 23 knew likewise the basic structure 2 intensifying effect and as reservoir underneath the passenger space or loading area 24 dienen.

The arrangement of the transmitting room 22 described here forms an additional reinforcement of the interior ground 20 and thus the basic structure 2. by the solvable or unsolvable attachment of the Unterbodens 21, whereby the interior ground 20 is enclosed, the basic structure 2 is likewise additionally reinforced, whereby the energy source 7 additionally with a Seitenaufprall protected wird.
