Definitions
- the invention relates to a body structure for an electrically operated vehicle according to the preamble of claim 1.
- a traction battery can be installed on the vehicle floor from underneath the vehicle.
- a body structure of the generic type is known from DE 10 2017 205 447 A1, which has an open mounting space for the traction battery, which is open in the vehicle vertical direction, downward from the vehicle.
- the mounting space is bounded by a floor panel part forming the vehicle floor, according to the vehicle.
- the traction battery can be inserted into the assembly space from the bottom of the vehicle, with the formation of a free assembly gap between a battery cover wall and the
- the battery top wall has stiffening beads. These are each formed with a bead base which is set back from a top wall base section by a bead height towards the inside of the battery.
- the bead base is in a power transmission system with the stiffening structure inside the battery.
- the spacer is as one
- hollow cylindrical sleeve formed with a sleeve base lying on the bead base.
- the sleeve base of the spacer is underneath using a fastening screw
- the object of the invention is to provide a body structure for an electrically operated vehicle, in which a structurally simple and reliable manner Power transfer from the vehicle floor into the stiffening structure of the traction battery can take place.
- the spacer is no longer completely rigid, but rather is constructed in two parts from a buffer and a base.
- the buffer is made of an elastically resilient soft component
- the spacer base is made of a hard component.
- Spacers are made of plastic in a two-component injection molding process.
- the spacer is designed so that in an undeformed production state the spacer height is greater than the gap dimension of the assembly gap between the traction battery and the vehicle floor. In this case, the
- the spacer can, on the one hand, be firmly connected to the battery cover wall and, on the other hand, be supported in loose contact against the underside of the base plate part.
- connection is realized as a structurally simple adhesive connection, in which a base adhesive surface of the spacer is glued to the battery top wall via an adhesive layer.
- At least one can be in the battery cover wall
- Stiffening bead should be formed.
- the stiffening bead can be embossed from the top of the vehicle into the planar top wall base section. In this case, the
- Stiffening bead have a bead base set back from the top wall base section by a bead height towards the battery.
- the ribbed bottom can be in
- the battery cover wall can preferably be screwed to the stiffening structure inside the battery, specifically at a screwing point at which a fastening screw advances the bead base
- Stiffening bead braced with the battery-internal stiffening structure.
- the screw head of the fastening screw is preferably positioned in a space-saving manner within the stiffening bead, without protruding in the vertical direction of the vehicle above the planar one
- the stiffening structure inside the battery is preferably in Battery crossmember running in the transverse direction of the vehicle, which can transmit impact forces to the side of the vehicle facing away from the crash on both sides, at least in a side crash.
- the spacer base has a supporting contour, by means of which the spacer is supported directly on the bead base.
- the above-mentioned spacer support contour is preferably functional and locally separate from the base adhesive surface.
- the spacer support contour can be supported in loose contact on the bead base.
- the base adhesive surface can be glued offset to the base support contour on the top wall base section, that is to say glued outside the stiffening bead.
- the at least one stiffening bead can extend in the transverse direction of the vehicle to an outer side edge of the battery cover wall and can be open to the outside of the vehicle in the transverse direction of the vehicle. In this way, water or impurities that collect in the stiffening bead can be discharged in a discharge direction along the stiffening bead to the outside of the vehicle. It has been shown that there is a high dust and / or liquid entry from the outside of the vehicle during ferry operation. The removal of
- Water / impurities are favored by providing the stiffening bead.
- the base-supporting contour of the spacer can preferably not fill the entire bead cross-section, but rather be supported on the bead base to form a passage that is free in the discharge direction.
- the base support contour can have two support ribs supported on the bead base, between which the free passage is formed.
- only one support rib can be provided, which is free on both sides to the bead walls of the
- Stiffening bead is supported on the bead base.
- the stiffening bead can be channel-shaped in profile cross-section with two bead walls raised from the bead base. These can merge into the planar top wall base section at transition edges.
- the base support contour transitions into the base adhesive surface transversely to the longitudinal direction of the bead and on both sides with a positioning contour with an intermediate layer.
- the respective positioning contour can be implemented as a positioning flank which is in a form-fitting contact with the respective bead wall.
- the adhesive connection of the spacer to the battery cover wall is functional and / or locally independent of the screw connection of the battery cover wall to the stiffening structure inside the battery. In this way, the positioning of the spacers can be accomplished independently of the positioning of the screwing points, which results in degrees of freedom when assembling the body structure.
- Figure 1 is a partial perspective view of a body structure
- Figure 2 is a side sectional view of the assembled position of the traction battery in the body structure
- Figures 3 and 4 each have different views of spacers according to the invention.
- FIG. 1 shows a body structure of a two-lane vehicle
- the body structure has two side sills 1 running in the vehicle longitudinal direction x, of which only one is shown in FIG. 1.
- the sill 1 extends in the vehicle longitudinal direction x between a front A-pillar 3 and a rear C-pillar 5 and delimits side door openings 7 on the floor side.
- a crash-sensitive traction battery 9 is installed in the vehicle floor of the body structure. This is positioned below a floor panel part 10 and extends in the vehicle transverse direction y between the two sills 1. In the vehicle longitudinal direction x, the traction battery 9 extends between a front cross member and a rear cross member, which are not shown in the figures.
- the traction battery 9, viewed in the vehicle vertical direction z, is positioned approximately at the same height as the sills 1.
- the traction battery 9 has a battery housing 13 in FIG. 2, namely with a housing side wall 16, a top wall 15 and a bottom wall 17.
- the housing side wall 16 is formed with a laterally projecting housing flange 19 which engages under the sill 1 and with this in a screw connection 21.
- FIG. 2 only half of the body structure up to the vehicle center plane E is shown. The other half, not shown, is designed to be approximately a mirror image of this. In the event of a side crash, the
- the traction battery 9 is first inserted in a joining direction from the vehicle below into an assembly space 12 which is defined by the two front and rear body cross members as well as the side sills 1 and the floor panel part 10. Then the housing flange 19 of the traction battery 9 is screwed to the front and rear body cross members and the sills 1, to be precise with the formation of a free assembly gap 27 between the battery top wall 15 and the
- Stiffening beads 31 formed, of which only one is shown in Figure 3 or 4.
- the stiffening bead 31 has one of a top wall base portion 33 around one
- the bead base 35 is at a screw point 37 in a power-transmitting system with the battery cross member 25.
- the spacers 29 are directly in the
- Load case integrated in a transverse load path (in the event of a side crash) and / or in a vertical load path.
- Spacers 29 are formed in two parts from a buffer 39 and a base 41.
- the buffer 39 is made of an elastically resilient plastic soft component
- the base 41 is made of a rigid plastic component that is rigid with respect to the component.
- An essential aspect of the invention is that, in the installed position, the spacer 29 is supported between the base plate part 10 and the battery top wall 15 with elastic deformation of the buffer 39.
- the overall height h (FIG. 4) of the spacer 39 in the undeformed state of manufacture is larger than the gap dimension of the assembly gap 27, as indicated in Figure 4.
- the spacer 29 is shown in the undeformed production state, contrary to the actual installation position.
- the spacer base 41 has on its bottom side a support contour made up of two spaced apart support ribs 42, which are supported in loose contact on the bead base 35.
- a free passage 44 described later is defined between the two support ribs 42.
- the base support contour extends in the vehicle longitudinal direction x (that is to say transversely to the longitudinal direction of the beads) on both sides to the front and to the rear with the interposition of a positioning flank 47 in a front base adhesive surface 43 and a rear base adhesive surface 49, which are glued to the planar top wall base section 33 with the interposition of an adhesive layer 45.
- Adhesive connection is therefore offset outside the stiffening bead 31 and by an offset dimension Dc (FIG. 4) from the support contour 42.
- the two positioning flanks 47 of the spacer base 41 are in positive, loose contact with the respective bead walls 51 of the stiffening bead 31, which merge into the planar cover wall base section 33 at transition edges 53.
- the screw point 37 which is only indicated in FIGS. 2, 3 and 4, has a fastening screw, not shown, the screw head 57 (FIGS. 2 or 3) of which is positioned within the stiffening bead 31 in a space-saving manner.
- the stiffening bead 31 extends in the vehicle transverse direction y to the vehicle outer side edge of the battery top wall 15 and is open to the vehicle exterior in the vehicle transverse direction y. In this way, water or contaminants that collect in the stiffening bead 31 during the ferry operation can be discharged in the transverse direction y in a discharge direction A (FIG. 3) to the outside of the vehicle, specifically through the free passage 44 of the spacer 29.
