[0027] Now, example embodiments according to this application will be described in greater detail by referring to the accompanying drawings. These example embodiments can be implemented in a variety of different forms, and should not be construed as being limited only to the implementations set forth herein. It is understood that the embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art, and in the drawings, the thicknesses of layers and regions are exaggerated for clarity, and the same reference numerals are used throughout the drawings to designate the same elements, and thus a description thereof will be omitted.

[0028] In the prior art field of vehicle front-end cooling systems, the cooling assembly is a core component for ensuring the thermal management efficiency of the engine and the entire vehicle, and the connection mode of the cooling assembly with the frame assembly directly affects the operation stability of the cooling system. At present, a single suspension structure or a simple rigid connecting piece is generally used in the industry to achieve the fixed installation of the cooling assembly with the frame assembly. In this type of installation mode, the installation stability of the cooling fan assembly completely depends on the load bearing strength of a single connection point or the anti-deformation ability of a linear connection structure.

[0029] However, during actual driving, especially under complex road conditions, the vehicle will generate multi-directional and high-frequency dynamic loads, which directly act on the connection part of the cooling fan assembly. Due to the lack of effective load dispersion mechanism in the single connection structure, problems such as installation reference deviation, excessive axial and radial swing amplitude of the cooling fan assembly are easily caused. At the same time, the design of the traditional connection structure does not optimize the stress direction of the cooling fan assembly, and the force transmission path of the connection part is linearly distributed, so that the cooling fan assembly is prone to form a local stress concentration area at the connection part when bearing dynamic loads. Long-term bearing of uneven loads will cause fatigue damage to the connection structure.

[0030] The above problems not only reduce the installation precision of the cooling assembly, causing the relative position deviation of the cooling fan assembly and the surrounding core components such as the radiator and the condenser, affecting the guiding effect and cooling efficiency of the cooling airflow, but also may cause mechanical interference between the cooling fan assembly and the surrounding components due to excessive swing of the cooling fan assembly, causing abnormal noise, component wear, and even cooling system shutdown failure, ultimately significantly reducing the working reliability and overall service life of the cooling system, and being difficult to meet the use requirements of modern vehicles for high stability and long service life of the thermal management system.
