A forehold cross beam structure of an electric vehicle comprises a forehold cross beam assembly, a left front longitudinal beam assembly, a chassis front auxiliary frame and a right front longitudinalbeam assembly. The left front longitudinal beam assembly and the right front longitudinal beam assembly are a bilateral symmetry structure on the whole. A rear end of a main body of the left front longitudinal beam assembly is located on a rear left portion of a front end, and the rear end of the main body of the right front longitudinal beam assembly is located on a rear right portion of the front end. And the left and right side surfaces of the middle ends of the main body of the left front longitudinal beam assembly and the main body of the right front longitudinal beam assembly are inwards convex arc surfaces. And a front auxiliary frame front mounting bracket and a front auxiliary frame rear mounting bracket are fixedly arranged on the main bodies of the left front longitudinal beamassembly and the right front longitudinal beam assembly. A cross beam middle main body is further provided with a cross beam left connector and a cross beam right connector. And the rear ends of the main bodies of the left front longitudinal beam assembly and the right front longitudinal beam assembly and the rear end of the cross beam middle main body are fixedly connected with a dash panel assembly. And a battery pack is detachably fixed below the bottom plate of a carriage. The structure has the advantages of light weight of the whole structure, good rigidity and a high battery capacity.
电动车的前舱横梁结构,包括前舱横梁总成、左前纵梁总成、底盘前副车架、右前纵梁总成。左前纵梁总成和右前纵梁总成总体呈左右对称结构。左前纵梁总成的主体的后端的后端位于其前端的左后方,右前纵梁总成的主体的后端的后端位于其前端的右后方。左前纵梁总成的主体和右前纵梁总成的主体的中端的左右侧面均为内凸的弧面。左前纵梁总成及右前纵梁总成的主体上固设有前副车架前安装支架和前副车架后安装支架。横梁中部本体上还设有横梁左接头,横梁右接头。左前纵梁总成及右前纵梁总成的主体的后端、横梁中部本体的后端均和前围板总成固连。电池包可拆固定在车厢底板的下方。本发明具有整体结构重量轻、刚性好、电池容量高。
