The invention discloses a girder and an electric vehicle frame. The girder comprises a girder body, the girder body comprises a main beam and a sealing plate, the main beam is a sheet metal part and is composed of a first plate, a second plate, a third plate and a fourth plate, the first plate, the second plate, the third plate and the fourth plate are integrally bent to form a hollow pipe fitting, and the sealing plate is arranged on the first plate. A notch used for installing a head pipe is formed in the upper end of the hollow pipe fitting, and the lower end of the hollow pipe fitting is connected with the sealing plate. The girder adopts the integrally formed sheet metal part, and has the characteristics of convenience and quickness in production, high strength and light weight; the girders and the side beams of the frame are made of sheet metal parts, pedal mounting points and battery pressing strip mounting points can be directly integrated on the side beams, the number of stamping parts is reduced, the overall strength is improved, and the weight of the frame is reduced.
本发明公开一种大梁及电动车车架,该大梁包括大梁本体,所述大梁本体包括主梁、封口板,所述主梁为钣金件,其由第一板、第二板、第三板、第四板构成,所述第一板与所述第二板、所述第三板、所述第四板一体折弯成型为一中空管件,所述中空管件的上端形成有用于安装头管的槽口,所述中空管件的下端与封口板相连。本发明的大梁采用一体成型的钣金件,具有生产方便、快捷,强度高,重量轻的特点;本发明车架的大梁、边梁都采用钣金件制成,可以直接将脚踏板安装点、电池压条安装点集成在边梁上,减少了冲件数量,提高了整体强度,降低了车架重量。
