The invention belongs to the technical field of two-wheeled vehicles, and discloses a vehicle frame structure and a two-wheeled vehicle, the vehicle frame structure is provided with a damping seat, and the damping seat is rotatably connected with a girder through a folding rotating shaft, so that a vehicle frame has a turning type folding effect; secondly, the damping seat is rotationally connected with the rear fork, the rotating axis is parallel to the ground, a first damping groove is formed in the damping seat, a second damping groove is formed in the rear fork, the first damping groove and the second damping groove are matched to form a damping cavity, the damping elastic piece is arranged in the damping cavity, and the deformation direction of the damping elastic piece is perpendicular to the ground; the frame has a damping effect; thirdly, the damping elastic piece is arranged in the damping cavity, the influence and damage of external environment factors on the damping elastic piece are avoided, and then the risk of damping failure is reduced; in addition, when the damping elastic piece fails in elasticity, the damping seat has the functions of buffering swing stress of the girder and reducing stress of the girder.

    本发明属于两轮车技术领域,公开了一种车架结构及两轮车,该车架结构设置减震座,减震座与大梁通过折叠转轴转动连接,使得车架具有转折式折叠的效果;其次,减震座与后叉转动连接,且转动的轴线与地面平行,在减震座上开设第一减震槽,在后叉上开设第二减震槽,使第一减震槽和第二减震槽配合形成减震腔,将减震弹性件设置在减震腔内,减震弹性件的变形方向与地面垂直,使得车架具有减震的效果;再次,将减震弹性件设置在减震腔内,避免了外界环境因素对减震弹性件的影响和损坏,进而降低减震失效的风险;又次,当减震弹性件弹性失效时,减震座具有为大梁缓冲摆动应力,减小大梁受力的作用。
