Abstract

An optical lens assembly is disclosed, which including a lens unit and a holder, wherein the lens unit includes at least a front lens and a rear lens, and the holder includes a positioning portion and a holding portion extended downwardly the positioning portion, wherein the positioning portion and the holding portion are integrated with each other, wherein the holding portion forms a light chamber for holding the lens unit therein, wherein the light chamber allows imaging lights to enter thereinto and pass through the lens unit, wherein the positioning portion is sealed on the outer surface of the front lens along the outer periphery of the front lens.

Claims

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 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 the positioning portion is sealedly provided on an outer surface of the front lens along an outer periphery of the front lens of the lens unit, wherein the light chamber has an inner wall, wherein the holding portion is extended form the inner wall of the light chamber of the receiving portion, wherein the holding portion is sealedly provided against on an outer surface of the rear lens of the lens unit.

2. The optical lens assembly, as recited in claim 1, wherein the holder further comprises a base extended downwardly from the receiving portion, wherein the base is integrated with the receiving portion.

3. The optical lens assembly, as recited in claim 1, wherein the positioning portion of the holder comprises a positioning ring, wherein the positioning ring is sealedly provided on the outer periphery of the front lens along the outer periphery of the front lens of the lens unit.

4. The optical lens assembly, as recited in claim 2, wherein the positioning portion of the holder comprises a positioning ring, wherein the positioning ring is sealedly provided on the outer periphery of the front lens along the outer periphery of the front lens of the lens unit.

5. The optical lens assembly, as recited in claim 1, further comprising a casing, wherein the casing is sealedly provided on an outer surface of the holder to hide the holder inside the casing.

6. The optical lens assembly, as recited in claim 2, further comprising a casing, wherein the casing is sealedly provided on an outer surface of the holder to hide the holder inside the casing.

7. The optical lens assembly, as recited in claim 4, further comprising a casing, wherein the casing is sealedly provided on an outer surface of the holder to hide the holder inside the casing.

8. 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, at least one holding portion and a base extended from the receiving portion, wherein the receiving portion and the base are integrated with each other, 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 therein and pass through the lens unit, wherein the positioning portion is sealedly provided on an outer surface of the front lens along an outer periphery of the front lens of the lens unit, wherein the light chamber has an inner wall, wherein the holding portion is extended from the inner wall of the light chamber of the receiving portion, wherein the holding portion is sealedly provided against on an outer surface of the rear lens of the lens unit.

9. The optical lens assembly, as recited in claim 8, wherein the positioning portion of the holder comprises a positioning ring, wherein the positioning ring is sealedly provided on the outer periphery of the front lens along the outer periphery of the front lens of the lens unit.

10. The optical lens assembly, as recited in claim 8, further comprising a casing, wherein the casing is sealedly provided on an outer surface of the holder to hide the holder inside the casing.
