Abstract

Disclosed are a vehicle lamp optical element, a vehicle lamp module comprising the vehicle lamp optical element, a vehicle headlamp, and a vehicle. The vehicle lamp optical element comprises a light incoming part, a transmission part and a light exiting part, which are sequentially arranged. The light incoming part includes at least one light incoming structure. The rear end and the front end, in a light exiting direction, of the transmission part are respectively a light incoming end and a light exiting end of the transmission part. One end, facing away from the light exiting end of the light exiting part forms a light exiting face. The light exiting face is a curved face protruding forwards. The distance between at least one set of opposite side faces of the transmission part gradually increases from the end approaching the light incoming end to the end approaching the light exiting end.
