The invention discloses a vehicle bottom frame and a vehicle. The vehicle bottom frame comprises a floor bottom frame, a vehicle frame and a first connecting structure. The floor underframe is provided with a floor cross beam, and a reinforcing frame is arranged on the floor cross beam; the vehicle frame is provided with a vehicle frame longitudinal beam, and the floor cross beam is fixedly connected to the upper portion of the vehicle frame longitudinal beam; the first connecting structure is fixedly connected between the reinforcing frame and the frame longitudinal beam. The overall structure of the vehicle bottom frame is more stable, the length and the number of welding seams between the floor chassis and the frame are effectively reduced when the vehicle body is buckled, and therefore the field welding workload and the welding seam corrosion prevention workload are reduced, the machining and manufacturing cost is reduced, positioning between the vehicle body and the frame can be more accurate, and the vehicle body and the frame are more stable. Therefore, the consistency of finished automobile production is ensured.

    本发明公开了一种车辆底部框架和车辆,其中车辆底部框架包括:地板底架、车架和第一连接结构。所述地板底架具有地板横梁,所述地板横梁上设置有加强框架;所述车架具有车架纵梁,所述地板横梁固定连接在所述车架纵梁的上方;所述第一连接结构固定连接在所述加强框架与所述车架纵梁之间。该车辆底部框架的整体结构更稳定,而且有效的减小了车身扣合时地板底架与车架之间的焊缝长度和数量,从而降低了现场焊接的作业量和焊缝防腐工作量,进而降低了加工制造成本,并且能够使车身与车架之间的定位更精准,以保证了整车生产的一致性。
