1. A headlamp optical element, comprising a light collecting part, a light emitting part and a reflecting part which are connected in sequence along a light emitting direction, wherein
one end of the reflecting part is connected with a lower portion of the light emitting part, and the other end of the reflecting part is provided with a low beam cutoff line structure for forming a low beam cutoff line;
the low beam cutoff line structure is arranged on a front edge of a reflecting surface of the reflecting part; the light collecting part is a light concentrating cup structure, an end of the light collecting part away from the reflecting part is provided with a concave cavity, the concave cavity comprises a front light incident surface and a lateral light incident surface, the front light incident surface is a curved surface protruding to a side away from the reflecting part, the lateral light incident surface is a curved surface of which the circumference gradually decreases from an end away from the reflecting part to an end close to the reflecting part, and an outer contour surface of the light collecting part is a curved surface of which the circumference gradually increases from the end away from the reflecting part to the end close to the reflecting part; a lower portion of the light collecting part is provided with a region III light shape forming structure, part of light converged by the light collecting part can be emitted from the region III light shape forming structure and emitted under the reflecting part to form a light shape of a low beam region III.
