The invention relates to the technical field of automobiles, and discloses an automobile side collision doorsill reinforcing structure which comprises a doorsill outer plate. A threshold inner plate; the first connecting supports are arranged between the doorsill inner plate and the floor lower longitudinal beam at intervals in the length direction of the doorsill inner plate, at least one first connecting support is provided with an extending section which is in lap joint with the floor lower longitudinal beam, and a first battery pack mounting hole is formed in the overlapping position of the extending section and the floor lower longitudinal beam; the second connecting support is arranged between the rear end of the floor lower longitudinal beam and the rear doorsill rear connecting plate, one end of the second connecting support abuts against the rear doorsill rear connecting plate, the other end of the second connecting support is provided with an extending panel in lap joint with the floor lower longitudinal beam, and the extending panel is arranged between the floor lower longitudinal beam and the rear longitudinal beam front section. A second battery pack mounting hole is formed in the overlapping part of the extension panel, the floor lower longitudinal beam and the front section of the rear longitudinal beam. Collision loads can be distributed on a large stress bearing face, and the side face anti-collision performance and the safety performance of a vehicle are improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a reinforcing structure for a side sill of an automobile. Background technique [0002] The side impact performance of automobiles is an important part of the evaluation of vehicle safety performance, and is directly related to the life safety of passengers. Pure electric vehicles generally set the battery pack at the bottom of the car, while the existing car door sill structure is separated from the battery pack frame. When the side of the car is collided, the collision energy received by the side sill structure of the car is difficult to transfer to the underfloor rail or the battery. Therefore, it is difficult to distribute the collision load more evenly on a larger force surface, which affects the crash resistance and safety performance of the vehicle. SUMMARY OF THE INVENTION [0003] In view of the above problems, the purpose of the present invention is to provide a ...
