The threshold beam assembly 100 can be set to high-strength steel or other composite materials. When the vehicle collides, the threshold beam assembly 100 can absorb and disperse the impact energy in the lateral and front and rear directions, thereby ensuring the safety of the occupants.

[0035] Specifically, the sill beam assembly 100 is arranged below the vehicle door, and is provided with a sill beam outer panel 1 and a sill beam inner panel 2.

After the threshold beam assembly 100 collides, the reinforcing beam 4 can be repaired, replaced, etc., which is convenient for later maintenance and reduces maintenance costs. The front-to-back direction is not limited to the positive front-to-back direction, but can also refer to a direction with a smaller angle to the front-to-back direction, that is, a direction with an angle of 3° or 5° to the front-to-back direction.
