Battery housing with a frame structure composed of frame structure parts

摘要

Battery housing with a frame structure (4) enclosing a battery module receptacle, composed of several frame structure parts, each frame structure part at least two interconnected profiles (5, 6), of which at least one first profile (6) adjoins the second profile (5) with its end face , characterized in that the first profile (6) with the second profile (5) along at least two adjacent, by one of the profile longitudinal extension following profile outer edge (11, 11.1, 11.2) separated legs with a profile outer edge (11, 11.1 , 11.2) of the first profile (6) extending weld seam (18) is connected, wherein the profile outer edge (11, 11.1, 11.2) of the first profile (6) separating the adjacent legs to provide a material thickening with regard to its wall thickness in the area of the profile outer edge (11 , 11.1, 11.2) is designed as a welding specification with an outer circular arc (12) and an inner circular arc (13), wherein the radius of the inner circular arc (13) is greater than the radius of the outer circular arc (12) and that the profiles (5, 6) of the frame structure parts have a single-chamber or multi-chambered hollow-chamber profile leg (7, 7.1) through which the battery module receptacle is enclosed , and an angled to it, in the plane of the battery housing (1) extending support legs (14, 14.1), at least the profile outer edge of the hollow chamber profile leg (7, 7.1) closer to the battery module receptacle to the inner circular arc (13) which is larger with respect to its radius Providing a material thickening as a welding specification.
