Optical lens assembly for vehicular optical imaging system
First Claim
1. An optical lens assembly for vehicular optical imaging system, comprising:
- a lens unit, wherein the lens unit comprises at least a front lens and a rear lens; and
a holder, wherein the holder comprises a positioning portion, a receiving portion extended downwardly from the positioning portion and at least one holding portion, wherein the positioning portion and the receiving portion are integrated with each other, wherein the positioning portion, the receiving portion and the holding portion are integrally formed at the holder, wherein the receiving portion defines a light chamber, wherein the lens unit is provided in the light chamber, wherein the light chamber allows imaging light to enter thereinto and pass through the lens unit, wherein an inner diameter of the light chamber becomes larger from bottom to top that a diameter size of the positioning portion is larger than that of the receiving portion, and the diameter size of the receiving portion is larger than that of the holding portion, so as to allow the front and rear lenses being received in the light chamber from bottom to top, wherein an outer surface of the front lens is retained at the positioning portion that an outer periphery of the front lens is pressed and sealed at the positioning portion, wherein the light chamber has an inner wall, wherein an outer surface of the rear lens is retained at the holding portion that an outer periphery of the rear lens is pressed and sealed at the holding portion.
