Abstract

The utility model discloses an optical lens group, a sensor and a vehicle. The optical lens group comprises a receiving lens and at least one transmitting lens. The receiving lens comprises a plurality of sub-receiving lenses, the transmitting lens is arranged on the peripheral side of the receiving lens, the transmitting lens comprises a plurality of sub-transmitting lenses, and the plurality of sub-receiving lenses and the plurality of sub-transmitting lenses are distributed along the circumferential direction of the receiving lens. According to the embodiment of the utility model, the transmitting lens is arranged on the peripheral side of the receiving lens, the transmitting lens comprises a plurality of sub-transmitting lenses, the receiving lens can receive light rays emitted by different transmitting lenses, and the transmitting lens comprises a plurality of sub-transmitting lenses, and the receiving lens comprises a plurality of sub-receiving lenses. The plurality of sub-receiving lenses can receive the light of the plurality of sub-transmitting lenses, so that the utilization rate of the transmitting lenses on the light can be increased, the optical sensing area is increased, the sensitivity of a product with the optical lens group is improved, the structure and the size of the optical lens group can be reduced, and the integrated design of the optical lens group is facilitated.
