The invention provides an electric vehicle frame and an electric vehicle, and relates to the technical field of electric vehicles. The electric vehicle frame comprises a front supporting assembly, a left protection plate, a right protection plate and a rear supporting assembly, the left protection plate and the right protection plate are of an integrally-formed structure, and the left protection plate and the right protection plate are each divided into a transverse extending area and a triangular area connected with the transverse extending area; the other ends of the transverse extending areas of the left protection plate and the right protection plate are symmetrically arranged on the two sides of the front supporting assembly respectively, and the triangular areas of the left protection plate and the right protection plate are further connected with the rear supporting assembly respectively. According to the electric vehicle frame, through structural optimization, a plurality of parts are combined, the number of the parts is greatly reduced, the structure is simple, and cost is low; moreover, material preparation procedures are reduced, welding beads are reduced, the production time is reduced, and the production efficiency is high; the sheet metal parts are adopted to replace pipe materials, the left protection plate and the right protection plate are integrally formed, the machining precision is high, and therefore light weight and high quality are achieved.

    本申请提供一种电动车车架及电动车,涉及电动车技术领域。该电动车车架,包括:前部支撑组件、左护板、右护板和后部支撑组件,左护板和右护板为一体成型结构,左护板和右护板上分别划分有横向延伸区域和与横向延伸区域连接的三角区域,左护板和右护板的横向延伸区域的另一端分别对称设置在前部支撑组件的两侧,左护板和右护板的三角区域还分别与后部支撑组件连接。该电动车车架通过结构优化,将多个零件合并,大大减少了零件的数量,结构简单,成本较低;而且,备料工序减少,焊道减少,生产工时减少,生产效率较高;采用钣金件代替管料,左护板和右护板一体成型,加工精度高,从而具有较轻的重量以及较高的品质。
