Abstract
A high beam and low beam switching device, a vehicle lamp comprising the high beam and low beam switching device, and a vehicle, the device comprising a light shielding plate, an impeller, and a driving device that is used for driving the light shielding plate and the impeller to rotate forwards and backwards; and a limiting mechanism used for limiting the rotation angle of the light shielding plate is provided between the light shielding plate and the driving device. The high-beam and low-beam switching device can achieve the successful switching of a high beam and a low beam, and the use of a vehicle lamp will not be affected; mist or moisture in the interior of the vehicle lamp can be removed, and meanwhile, the heat dissipation effect of the vehicle lamp can be improved, and the space that is occupied by the vehicle lamp will not be increased.
