Title:

FRONT VEHICLE BODY STRUCTURE AND VEHICLE

Document Type and Number:

WIPO Patent Application WO/2021/052411

Kind Code:

A1

Abstract:

A front vehicle body structure, comprising front longitudinal beams (100), a dash panel (200), a front floor (300), and side longitudinal beams (400). A rear edge portion (210) connected to the front floor (300) is provided at the lower end of the dash panel (200); each front longitudinal beam (100) comprises a longitudinal beam front section (110) and a longitudinal beam rear section (120); the longitudinal beam front section (110) is provided on the front side of the dash panel (200) and is connected to the dash panel (200); the longitudinal beam rear section (120) extends along a front-back direction of the vehicle body and at least extends to the lower side of the rear edge portion (210); each side longitudinal beam (400) is separately connected to the dash panel (200) and the longitudinal beam rear section (120) so that the side longitudinal beams (400), the dash panel (200), and the longitudinal beam rear sections (120) form a force transmission closed-loop structure. According to the front vehicle body structure, the longitudinal beam rear sections (120) of the front longitudinal beams (100) and the dash panel (200) are respectively connected to the side longitudinal beams (400) so that the side longitudinal beams (400), the dash panel (200), and the longitudinal beam rear sections (120) form the force transmission closed-loop structure, collision force of the front longitudinal beams (100) is dispersed and transmitted to the side longitudinal beams (400), a force transmission effect of the vehicle body is effectively improved, a stress at a joint of the rear edge portion (210) and the front floor (300) is reduced, and the structural reliability of the vehicle body is improved. Also disclosed is a vehicle, comprising the front vehicle body structure.
