Abstract

The invention discloses an integral pure aluminum electric vehicle frame. The integral pure aluminum electric vehicle frame comprises threshold beams arranged on the two sides of a battery pack in a mirror image structure and used for bearing the battery pack, one ends of the threshold beams are in threaded connection with a front longitudinal beam assembly through a longitudinal beam fixing seat,and the other ends of the threshold beams are in threaded connection with a rear longitudinal beam assembly through a longitudinal beam fixing seat; the front longitudinal beam assembly is provided with mounting brackets, wherein the mounting brackets are in riveted connection with the front longitudinal beam assembly, and are arranged in a symmetrical structure, and provided with shock absorbersand upper control arms which are integrated; and the rear longitudinal beam assembly is provided with shock absorber brackets, wherein the shock absorber brackets are in riveted connection with the rear longitudinal beam assembly and are arranged in a symmetrical structure. The beneficial effects of the integral pure aluminum electric vehicle frame are mainly embodied in that a production technology is simple, an assembly mode of small-range welding and large-range assembling is adopted to ensure assembly precision and connecting strength, and the production efficiency is greatly improved while safety is ensured; and in addition, the integral pure aluminum electric vehicle frame has high universality and is wide in applicability.
