Abstract
A housing part, in particular a lower housing part, of an energy storage housing, has two mutually spaced longitudinal elements which run in parallel with one another and extend in a longitudinal direction. The longitudinal elements are connected at end faces via transverse elements. A planar base element is fastened to the longitudinal elements. The longitudinal elements have contact regions which are oriented towards the base element, by which contact regions the base element is fastened to the longitudinal elements. Three weld seams extending in the longitudinal direction are formed in each of the contact regions.
Claims17
A housing part of an energy storage housing, comprising:
- two mutually spaced longitudinal elements which run in parallel with one another and extend in a longitudinal direction,
- wherein the longitudinal elements are connected at end faces via transverse elements;
- a plate-shaped base element fastened to the longitudinal elements,
- wherein each of the two longitudinal elements has a contact region at a bottom thereof oriented toward the plate-shaped base element;
- and
- three weld seams extending in the longitudinal direction on the contact region of each longitudinal element by which each longitudinal element is connected to the plate-shaped base element,
- wherein a first of the three weld seams is configured on an inner edge of the contact region, a second of the three weld seams is configured on an outer edge of the contact region, and a third of the three weld seams is arranged centrally in a surface of the contact region.
A method for producing a housing part, comprising:
- providing a base element, and two longitudinal elements which extend in a longitudinal direction, wherein each of the two longitudinal elements has a contact region at a bottom thereof oriented toward the base element;
- and
- welding each of the two longitudinal elements to the base element via three weld seams in the contact region of each of the two longitudinal elements, the three weld seams extending in the longitudinal direction,
- wherein a first of the three weld seams is configured on an inner edge of the contact region, a second of the three weld seams is configured on an outer edge of the contact region, and a third of the three weld seams is arranged centrally in a surface of the contact region.
