[0053] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0054] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, left, right" are usually defined by the direction of the drawing, and "inner" and "outer" refer to the inside and outside of the relevant parts. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0055] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0056] With the development of new energy vehicles, lightweighting is the core technology and important development direction of the automotive industry. Lightweighting means reducing the weight of the vehicle without reducing the safety, reliability, comfort and cost of the vehicle, thereby improving the vehicle's power economy.

[0057] The layout of the front cabin of the vehicle is becoming more and more important. The entire front cabin of the vehicle needs to be lightweight and have high rigidity, because the vibration characteristics of the vehicle are closely related to the rigidity of the vehicle body. A high-rigidity vehicle body is not only conducive to the support of the suspension and the normal operation of the vehicle system, but also conducive to improving the vibration characteristics. Reducing the weight of the vehicle can also reduce the yaw inertia on the suspension, thus ensuring the handling performance of the vehicle.

[0058] The connection between the front cabin assembly and the front subframe assembly in the related technology often only considers the layout of the related components in the front cabin, and does not consider the impact of the overall stiffness performance of the entire front cabin. When the entire front cabin of the vehicle is hit by a collision, the load force is not transmitted well, which affects the overall stiffness of the entire front cabin of the vehicle, and further affects the performance of the entire vehicle.
