Abstract: A frame structure part for forming a frame structure Rs for a battery housing 1 of an electric motor-driven motor vehicle with at least two hollow chamber profiles 2, 2.1 which are connected to one another at an angle and each have at least two chambers 3, 3.1 and a mounting surface 5, 5.1 extending in the x-y plane and located on the upper side of the hollow chamber profiles 2, 2.1 in a common plane, is characterized in that a sealing fillet 7, 7.1 following the longitudinal extension of the hollow chamber profiles 2, 2.1 is introduced into the mounting surface 5, 5.1 for receiving a seal 8, wherein both hollow chamber profiles 2, 2.1-2.3 are mitered at the ends in a first profile section A extending from the mounting surface 5, 5.1 over the entire extension of the uppermost chamber in the z-direction, and the miter joints 8.1-8.3 are connected to one another, so that the butt-end openings of the sealing fillets 7, 7.1 of the two hollow chamber profiles 2, 2.

Abstract: A battery housing for an electric vehicle comprises a first housing part and a second housing part. The first housing part has a trough-type structure for receiving one or more battery modules. The second housing part is designed as a cover part for closing the first housing part. The housing parts have peripheral assembly flanges and are connected to one another on their assembly flanges by multiple fasteners extending through the assembly flanges. The assembly flange of at least one housing part carries multiple spacing elements arranged spaced apart from one another, each having a spacer arranged on the side of the assembly flange carrying the spacing element facing the assembly flange of the other housing part, wherein the spacer only covers a part of the total width of the assembly flange. A peripheral seal is located between and adhesively connected to the two assembly flanges.

Abstract: A battery case for a vehicle driven by an electric motor, said battery case comprising a tray part (1, 1.1, 1.2, 1.3) which has a base (2, 2.1, 2.2, 2.3) onto which side walls (3, 3.1, 3.2, 3.3) having a mounting flange (4) are molded, and comprising a frame structure (5, 5.1, 5.2) which surrounds the tray part (1, 1.1, 1.2, 1.3) on the outer side thereof and has a hollow chamber (11, 11.1, 11.2). The side walls (3, 3.1, 3.2, 3.3) of the tray part (1, 1.1, 1.2, 1.3) are at the same time part of the frame structure (5, 5.1, 5.2) and separate the tray interior from the hollow chamber (11, 11.1, 11.2) of the frame structure (5, 5.1, 5.2). The side walls (3, 3.1, 3.2, 3.3) with their mounting flange (4) are part of the frame structure (5, 5.1, 5.2) and the frame structure (5, 5.1, 5.2) has at least two additional frame members (6, 8, 3.1, 4.1, 13, 3.2, 4.2, 13.1) connected to the tray part (1, 1.1, 1.2, 1.3) for completing the frame structure (5, 5.1, 5.2), of which a first frame member (6, 3.1, 3.
