The invention belongs to the technical field of vehicles, and discloses a vehicle frame middle module connecting structure, a vehicle frame assembly and a vehicle, the vehicle frame middle module connecting structure is connected with a vehicle frame through a vehicle frame connecting plate and connected with vehicle frame middle modules through middle module connecting plates, the strength of the connecting structure between the vehicle frame and the vehicle frame middle modules can be improved, stress concentration is avoided, and the service life of the vehicle frame is prolonged. The first connecting part and the second connecting part are connected at the same time through the first reinforcing piece, the structural strength between the first connecting part and the second connecting part can be enhanced, in addition, in the first reinforcing piece, the thicknesses of the thickest positions of the first fillet and the second fillet are both larger than the thicknesses of the first extending plate and the second extending plate; therefore, the parts of the first fillet and the second fillet which are large in stress and most prone to stress concentration are thicker, so that the whole first reinforcer is stressed uniformly, and rigidity change is in smooth transition.
本发明属于车辆技术领域,公开了车架中部模块连接结构、车架总成及车辆,该车架中部模块连接结构通过车架连接板连接车架,通过中部模块连接板连接车架中部模块,能够增加车架与车架中部模块之间的连接结构强度,避免应力集中,并通过设置第一加强件同时连接第一连接部以及第二连接部,能够增强第一连接部与第二连接部之间的结构强度,此外,第一加强件中,第一圆角以及第二圆角的最厚处的厚度均大于第一延伸板以及第二延伸板的厚度,从而使应力较大且最容易产生应力集中的第一圆角以及第二圆角的部分较厚,以使整个第一加强件受力均匀,刚度变化平滑过渡。
