Frame Structural Part And Battery Housing With A Frame Structure Composed Of Such Frame Structural Parts

A frame structure part for forming a frame structure Rfor a battery housing of an electric motor-driven 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 hollow chamber profiles in a common plane, is characterized in that a sealing fillet following the longitudinal extension of the hollow chamber profiles is introduced into the mounting surface for receiving a seal wherein both hollow chamber profiles - are mitered at the ends in a first profile section A 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 butt-end openings of the sealing fillets of the two hollow chamber profiles adjoin one another, and in that the first hollow chamber profile in a second profile section B located in the z-direction below the first profile section A and adjoining the latter, bears with its end face against a side face of the second hollow chamber profile and is connected to the latter. Also described is a frame structure part composed of a frame structure part R, Ras part of a frame structure R, having a plurality of such frame structure parts R, Rof a battery housing of an electric motor-driven vehicle for accommodating one or more battery modules.
