The invention discloses a sectional type frame connecting structure which comprises a front section frame, a middle frame and a rear section frame, the middle frame is of a truss type structure used for bearing a battery pack, and the left side and the right side of the middle of the middle frame are each provided with a penetrating beam penetrating through the middle frame. The front end and the rear end of the penetrating beam respectively penetrate through the middle frame and are fixed with the front-section frame and the rear-section frame into a whole; a front section frame cross beam located in the front section frame is fixed to the front end of the penetrating beam, and a rear section frame cross beam located in the rear section frame is fixed to the rear end of the penetrating beam. The frame is divided into the front section, the middle section and the rear section, the structural strength of the middle frame is enhanced through the penetrating beams, meanwhile, the structural stability of a battery box in the middle frame is guaranteed, the frame torque requirement of a large-tonnage electric truck can be met, the axle bearing requirement is met, and frame stress is more reasonable.

    本发明公开了一种分段式车架的连接结构,包括前段车架、中部车架和后段车架,所述中部车架为用于承载电池包的桁架式结构,其中部左右两侧分别设置有一根贯穿所述中部车架的贯穿梁,所述贯穿梁的前后两端分别穿过所述中部车架与所述前段车架和所述后段车架固定为一体;所述贯穿梁的前端固定有位于所述前段车架内的前段车架横梁,所述贯穿梁的后端固定有位于所述后段车架内的后段车架横梁。本发明将车架分为前中后三段,通过贯穿梁加强中部车架的结构强度,同时保障了中部车架内电池箱的结构稳定,可适用于大吨位电动卡车的车架力矩要求,满足了车桥的承载要求,车架受力更合理。
