Background

The subframe can be regarded as a framework of the front axle and the rear axle, and is a component of the front axle and the rear axle. The subframe is not a complete frame, but merely a bracket that supports the front and rear axles and the suspension, through which the axles and suspension are then connected to the "main frame", conventionally referred to as the "subframe". The sub-frame has the functions of isolating vibration and noise and reducing direct entering of the sub-frame into a carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and the sub-frame is also arranged on an engine of some vehicles. Conventional vehicle bodies without sub-frames have suspensions that are directly connected to the body steel panels. Thus, the suspension rocker mechanisms of both the front and rear axles are discrete components and not an assembly. After the subframe is produced, the front and rear suspensions may be assembled to the subframe to form an axle assembly, which is then mounted to the vehicle body. The connection point of the subframe to the vehicle body is as in the case of an engine mount. Generally, an axle assembly needs to be connected with a vehicle body through four suspension points, so that the connection rigidity of the axle assembly can be guaranteed, and a good vibration isolation effect can be achieved. The main performance objectives for the subframe are therefore to reduce the introduction of road shocks and to increase the stiffness of the suspension system connections, so that the vehicle incorporating the subframe feels very solid and compact in its chassis when driven. In the prior art, the electric automobile has a complex structure and high requirements on structural strength and safety, the arrangement of the front cabin structure of the whole automobile is difficult due to the limitation of space and part structures, the assembly is inconvenient, and the balance between the stability and the operability of the whole automobile is poor.
