Abstract
A structure of an electric or hybrid vehicle includes a floor, a battery container secured beneath the floor, and a compressed foam plate arranged between the battery container and the floor.
Claims16
A stricture for an electric or hybrid vehicle, comprising:
- a floor;
- a battery tray secured beneath the floor;
- and
- a compressed foam plate arranged between the battery tray and the floor,
- wherein a surface of the foam plate comprises microscopic perforations configured for evacuating air contained in the foam when the foam plate is compressed and/or configured to avoid ingress of water into the foam, and
- wherein a density of the microscopic perforations is between 2 and 10 of the microscopic perforations per mm2 of the surface of the foam plate.

A vehicle, comprising:
- a floor;
- a battery tray secured beneath the floor;
- and
- a compressed foam plate arranged between the battery tray and the floor,
- wherein a surface of the foam plate comprises microscopic perforations configured for evacuating air contained in the foam when the foam plate is compressed and/or configured to avoid ingress of water into the foam, and
- wherein a density of the microscopic perforations is between 2 and 10 of the microscopic perforations per mm2 of the surface of the foam plate.
3 more elements
A method for assembling a vehicle structure comprising:
- perforating a foam plate;
- arranging the foam plate between a vehicle floor and a vehicle battery tray;
- compressing the foam plate to a degree of compression of between 20% and 40%;
- and
- securing the battery tray to the floor in such a way that the foam plate remains compressed to a degree of compression of between 20% and 40%,
- wherein a surface of the foam plate comprises microscopic perforations configured for evacuating air contained in the foam when the foam plate is compressed and/or configured to avoid ingress of water into the foam, and
- wherein a density of the microscopic perforations is between 2 and 10 of the microscopic perforations per mm2 of the surface of the foam plate.
