The invention belongs to the technical field of commercial vehicles, and discloses a middle vehicle frame, a vehicle frame assembly and a pure electric commercial vehicle. According to the middle frame, a cross beam structure comprises two cross beam end plates which are opposite in the first direction and distributed at intervals, and the cross beam end plates are used for being connected with frame longitudinal beams; the longitudinal beam structure comprises a longitudinal beam bottom plate and two longitudinal beam end plates which are opposite in the second direction and distributed at intervals, the two ends, in the first direction, of the longitudinal beam bottom plate are connected with the two cross beam end plates correspondingly, the two ends, in the first direction, of the longitudinal beam end plates are connected with the two cross beam end plates correspondingly, and the two ends, in the second direction, of the longitudinal beam bottom plate are connected with the two longitudinal beam end plates correspondingly; an accommodating space is formed among the longitudinal beam bottom plate, the two cross beam end plates and the two longitudinal beam end plates, and the accommodating space is used for accommodating a battery; the first direction is perpendicular to the second direction. The structural strength of the middle frame is effectively improved, the structural strength and working performance of a frame assembly formed by the frame longitudinal beams and the middle frame are improved, and the endurance mileage of the pure electric commercial vehicle is effectively increased.

    本发明属于商用车技术领域,公开了中车架、车架总成及纯电商用车。该中车架,横梁结构包括两个沿第一方向相对且间隔分布的横梁端板,横梁端板用于与车架纵梁连接;纵梁结构包括纵梁底板和两个沿第二方向相对且间隔分布的纵梁端板,纵梁底板沿第一方向的两端分别与两个横梁端板连接,纵梁端板沿第一方向的两端分别与两个横梁端板连接,纵梁底板沿第二方向的两端分别与两个纵梁端板连接;纵梁底板、两个横梁端板和两个纵梁端板之间形成容置空间,容置空间用于容置电池;第一方向与第二方向垂直。有效提升了中车架的结构强度,提升了车架纵梁与中车架形成的车架总成的结构强度和工作性能,且有效提升了纯电商用车的续航里程。
