The invention relates to a frame assembly mechanism and a vehicle, and the frame assembly mechanism can be applied to the vehicle. The frame assembly mechanism comprises a frame longitudinal beam, a first cross beam and a second cross beam. The first cross beam and the second cross beam are arranged on the frame longitudinal beam in a spaced mode in the extending direction of the frame longitudinal beam, the frame longitudinal beam is provided with a frame tail, the second cross beam is located at the frame tail, and the second cross beam is made of a reinforcing plate, so that the torsional rigidity of the tail of the frame assembly mechanism is improved. In addition, the frame longitudinal beam is also made from a reinforcing plate, so that the bending rigidity of the frame assembly mechanism is improved. The rigidity and the pressure bearing degree of the frame assembly are improved through improvement of the torsional rigidity and the bending rigidity, in the actual design process, a compartment assembly can be directly installed on the frame assembly mechanism, the performance requirement of the whole vehicle can be met, other frame structures do not need to be designed for assisting in pressure bearing, and therefore the whole vehicle height of the vehicle is reduced, the gravity center of the vehicle is lowered, and the safety of the vehicle is greatly improved.
本发明涉及一种车架总成机构及车辆,上述车架总成机构,可应用于车辆上。车架总成机构包括车架纵梁、第一横梁和第二横梁。第一横梁和第二横梁沿车架纵梁的延伸方向间隔搭设于车架纵梁上,车架纵梁具有车架尾部,第二横梁位于车架尾部,且第二横梁采用加强板制成从而提升了车架总成机构尾部的扭转刚度。并且,车架纵梁也采用加强板制成,提升了车架总成机构的弯曲刚度。通过扭转刚度和弯曲刚度的提成提高了车架总成的刚度和承压程度,在实际设计时,可以直接将车厢总成安装于车架总成机构上,即可满足整车性能需求,而不需要再设计其余车架结构辅助承压,从而使得车辆的整车高度得到了降低,车辆重心也随之降低,大大提升了车辆的安全性。
