High-energy-absorption structure of engine room

The invention relates to a high-energy-absorption structure of an engine room. The high-energy-absorption structure comprises a front longitudinal beam fixedly connected between an anti-collision beam and a side wall frame, a collapse beam is further fixedly connected between the front longitudinal beam and the anti-collision beam, and the front longitudinal beam comprises a main force transmission beam and an upper force transmission beam, wherein the main force transmission beam in a horn shape and the upper force transmission beam in a horn shape are fixedly connected between the collapse beam and the side wall frame. The upper force transmission beam is located above the main force transmission beam, and the small ends of the main force transmission beam and the upper force transmission beam are connected with the collapse beam. A guide beam in a horn shape is further fixedly connected between the upper force transmission beam and the collapse beam and obliquely arranged upwards relative to the main force transmission beam. The big end of the guide beam is connected with the collapse beam. The invention further relates to front wheel covers arranged among the main force transmission beam, the guide beam, the upper force transmission beam and a dash panel in a connecting mode. When an automobile collides, the high-energy-absorption structure can enable the front longitudinal beam and the collapse beam to absorb collision energy well, reduce influences on a passenger compartment by collision and meanwhile improve reliability of the front wheel covers.
