AI Technical Summary
In existing technologies, the structural strength of the torsion box is insufficient, which cannot effectively absorb and disperse the collision energy of the vehicle, affecting the collision safety and ride comfort of electric vehicles.
A torsion box assembly was designed, including a sill beam connection, a longitudinal beam connection, a main body, a first reinforcing rib, and a second reinforcing rib. The reinforcing rib is provided on the opposite surface of the main body to define the reinforcing cavity. The orthographic projection of the second reinforcing rib coincides with the first reinforcing rib, and together they absorb collision energy to improve structural strength.
It effectively absorbs and disperses collision energy, improves the impact resistance and structural strength of the torsion box assembly, and enhances the vehicle's collision performance and safety.
