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. Here, the spacing elements each have at least one arm guided around the lateral edge of the assembly flange carrying the spacing element, and reaching to the opposite side, and supported on the opposite side of the assembly flange.

A frame structure part for forming a frame structure for a battery housing of an electric motor vehicle with at least two hollow chamber profiles, which are connected to one another at an angle and each have at least two chambers and a mounting surface extending in the x-y plane and located on the upper side of the profiles in a common plane. A sealing fillet following the longitudinal extension of the profiles is introduced into the mounting surface for receiving a seal, wherein the ends of both profiles are mitered in a first profile section extending from the mounting surface over the entire extension of the uppermost chamber in the z-direction, and the miter joints are connected to one another, so that the joint-end mouths of the fillets of the two profiles adjoin one another. The first profile, in a second profile section located in the z-direction below the first profile section adjoining the same, bears with its end face against a side face of the second profile and is connected thereto. Also described is a battery housing with a frame structure having a plurality of such frame structure parts.

A dashboard support for a motor vehicle to be installed between and connected to two pillars located on opposite vehicle sides. The dashboard support has a support structure provided by a hollow profile, which support structure has at least one support portion having a curvature. A planar reinforcement part spanning this curved support portion on the inside of the curvature is arranged on the outside of the support structure. The planar extension of the reinforcement part faces toward the curvature and the ends of the reinforcement part facing in the spanning direction are connected to the outer surface of the support structure.

Dashboard support

The present disclosure relates to a support structure () for a vehicle, comprising a support () which has an upper shell () and a lower shell (), the extension of the support structure in the longitudinal extension of the vehicle being defined by the extension of the two shells () in said direction, and comprising attachment points () for connecting a link (). A front attachment point and a rear attachment point are provided on each link attachment side (). The two attachment points () are provided for an attachment insert () on each link attachment side () of the support (), wherein the attachment insert is connected to the shells (), is open towards a link () to be connected to the attachment points at least in the region of the attachment points (), and is produced as a separate component. This attachment insert has an upper chord (), a lower chord (), and a back section () connecting the upper chord () to the lower chord (), wherein the upper chord () of the attachment insert () is connected to the upper chord () of the support (), and the lower chord () of the attachment insert () is connected to the lower shell () of the support (), wherein link connection part receivers () provided by the attachment insert () are separated from the support () cavity located between the upper and the lower shell by the back section ().
