In a PHEV model (Plug-in hybrid electric vehicle ), a front subframe assembly is generally connected with a power assembly in a one-point suspension manner, that is, the front subframe and the power assembly are connected through an engine suspension manner.
In the connecting structure, the power assembly is connected with the front auxiliary frame assembly only through the engine suspension, when the vehicle collides with the front surface, the power assembly can move towards the tail direction under the influence of inertia of the power assembly, so that the backward movement amount of the power assembly is overlarge, the passenger cabin is possibly pressed or the power assembly is possibly caused to fire, and the safety hidden trouble is generated, so that the safety performance requirement cannot be met.
In view of this, this application provides a stop device, preceding sub vehicle frame assembly and vehicle, aims at solving when the vehicle took place the frontal collision, and power assembly is too big to the displacement of tail, and then the problem of the vehicle potential safety hazard that leads to.

The subframe is not a complete frame, but is a bracket that supports the front and rear axles, and the suspension, through which the axles, suspension are then connected to the "positive frame", conventionally referred to as the "subframe". The sub-frame is used for blocking vibration and noise and reducing the noise from directly entering the carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and some cars are also provided with the sub-frame for the engine. The conventional load-bearing vehicle body without a subframe has a suspension directly connected to the steel plate of the vehicle body. The front and rear axles are thus all part and not an assembly.

The limiting piece 2 comprises a plurality of plate-shaped structures, the plate-shaped structures are mutually connected to form a triangular supporting structure, and the triangular limiting piece 2 can bear larger impact force and has stronger stability and structural strength due to strong stability of the triangular structure.
The triangular support structure may be a triangular support structure formed by connecting three plate-like structures, or may be a triangular support structure formed by enclosing a plurality of plate-like structures and having a triangular space inside, so long as the impact resistance can be enhanced by utilizing the characteristic of high structural strength of the triangle, and the specific limitation is not imposed herein.
Through the arrangement, the mounting base 1 and the limiting piece 2 arranged on the mounting base 1 are used for achieving the effect of limiting and blocking the power assembly, and the limiting piece 2 is provided with a contact surface, so that the power assembly can be contacted with the power assembly moving towards the tail direction when a collision accident occurs to the vehicle, and the power assembly is limited. And the limiting piece 2 is formed into a triangular supporting structure by interconnecting a plurality of plate-shaped structures, and the supporting structure has stronger stability, so that the shock resistance of the limiting piece 2 is improved, and the kinetic energy of the power assembly is better absorbed after the limiting piece contacts with the power assembly. The problem that the power assembly is too large in displacement when the vehicle is proved to collide, and potential safety hazard is caused is effectively avoided.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or terminal. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or terminal device comprising the element.
The foregoing has outlined rather broadly the more detailed description of the present application, and the detailed description of the principles and embodiments herein may be better understood as being a limitation on the present application. Also, various modifications in the details and application scope may be made by those skilled in the art in light of this disclosure, and all such modifications and variations are not required to be exhaustive or are intended to be within the scope of the disclosure.
