[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a front-end module assembly and a front engine compartment. Background Art

[0002] During the driving process of an automobile, problems such as torsional deformation and vibration abnormal noise will occur. Especially when the vibration amplitude of the thermal management system is too large, it not only aggravates the torsional deformation degree of the vehicle body, but also increases the vibration amplitude of each component in the front engine compartment, thereby causing a decline in abnormal noise, vehicle durability, and handling performance, and even affecting pedestrian protection safety and vehicle maintenance economy. Among them, the stability of component installation is particularly important, which will directly affect the precise control of the appearance size gap and the economy of vehicle maintenance.

[0003] Among them, the performance of the front-end module, pedestrian protection standards, RCAR (Research Council for Automobile Repairs) indicators, NTF (Noise Transfer Function), etc. together constitute the crucial NVH (Noise, Vibration, Harshness) performance indicators in vehicle development, thus determining the overall performance of the vehicle.

[0004] Due to the small space and weak structural correlation of the traditional sheet metal crossbeam cavity structure, it is difficult to meet the integrated installation requirements of multiple components such as the front bumper frame, hood lock, AGS (Active Grille System), front speaker, radiator, etc.

[0005] In order to solve the above problems and provide installation points for the above-mentioned multiple components, the existing front engine compartment design tends to adopt a superimposed structure of "steel plate + steel plate", and uses a large number of structural parts and reinforcement parts to be fixed by welding to meet the body strength and performance requirements.
