The invention discloses a frame structure suitable for a heavy electric drive special vehicle chassis. The frame structure comprises a left longitudinal beam and a right longitudinal beam which are symmetrically arranged, a front end is connected with the left longitudinal beam and the right longitudinal beam through a front beam, and the middle of the left longitudinal beam and the middle of the right longitudinal beam are supported by a plurality of beam welding parts, a plurality of tail beam welding parts, a plurality of motor supporting seat welding parts and a plurality of steering reinforcing beam welding parts. A power unit upper supporting beam welding part and a power unit lower supporting beam welding part serve as a middle supporting beam, and support is provided for installation of a battery pack and a controller. According to the novel frame structure, all system interfaces can follow the traditional vehicle type structure, the arrangement space of the upper system interfaces is sufficient, the novel frame structure can serve as a universal frame, the frame structure is reasonable in design, novel in form and high in bearing capacity, the good cross-country performance and passing performance of a chassis can be guaranteed, and the novel frame structure is quite suitable for a novel full-electric-drive heavy special vehicle.
