Abstract

A camera for use on vehicles, in particular commercial vehicles. The camera has a housing including a first accommodation portion and a second accommodation portion, an optical element disposed within the first accommodation portion, and a digital image capturing unit provided on a circuit board. The circuit board is disposed within the second accommodation portion. The housing is formed by a first part consisting of plastic and a second part which is vapor resistant.

Claims

1. A camera having an optical axis for use on vehicles comprising:

a housing having a first accommodation portion and a second accommodation portion;

an optical element disposed along the optical axis within the first accommodation portion; and

a digital image capturing unit provided on a circuit board, the digital image capturing unit disposed along the optical axis and spaced from the optical element to define an optical path therebetween;

wherein the circuit board is disposed within the second accommodation portion, and

wherein the housing is formed from a first part consisting of plastic and a second part consisting of a vapor resistant material, the second part radially surrounding at least a portion of the optical element and the optical path in an overlapping manner about the optical axis in an axial direction such that penetration of vapor into the optical path disposed between the optical element and the digital image capturing unit is prevented.

2. The camera according to claim 1, wherein the second part is at least partially embedded within the first part.

3. The camera according to claim 1, wherein the second part is made of one of aluminum, zinc, magnesium, copper, and brass.

4. The camera according to claim 3, wherein the metal is one of aluminum, zinc, magnesium, copper and/or brass.

5. The camera according to claim 1, wherein the second part is one of a die-cast part and a continuous casting part.

6. The camera according to claim 1, wherein the optical element is screwed into the first accommodation portion via a thread.

7. The camera according to claim 1, wherein the first accommodation portion and/or the second accommodation portion is formed by the first part.

8. The camera according to claim 1, wherein the first accommodation portion and/or the second accommodation portion is formed by the second part.

9. The camera according to claim 1, wherein the first accommodation portion is cylindrically formed with a first diameter and/or the second accommodation portion is cylindrically formed with a second diameter, the first diameter being smaller than the second diameter.

10. The camera according to claim 9, further comprising a flange disposed between the first accommodation portion and the second accommodation portion, wherein the circuit board is attached to the flange.

11. The camera according to claim 1, wherein the second part is radially inwardly disposed with respect to the first part, or the second part is radially outwardly disposed with respect to the first part.

12. The camera according to claim 1, wherein the first part is connected to the second part by an injection moulding process.

13. The camera according to claim 1, wherein the housing further comprises a connection portion configured to mount the housing on a vehicle.

14. The camera according to claim 13, wherein the connection portion is integrally formed with the first part.

15. The camera according to claim 13, wherein the connection portion is configured to mount the housing to a commercial vehicle.

16. The camera according to claim 13, wherein the optical element is disposed within the first accommodation portion in a vapor resistant manner and/or the circuit board is disposed within the second accommodation portion in a vapor resistant manner.

17. The camera according to claim 1, wherein the optical element is disposed within the first accommodation portion in a vapor resistant manner and/or the circuit board is disposed within the second accommodation portion in a vapor resistant manner.

18. The camera according to claim 17, wherein the first accommodation portion and/or the second accommodation portion is formed by the first part.

19. A camera having an optical axis for use on vehicles comprising:

a housing having a first accommodation portion and a second accommodation portion;

an optical element disposed along the optical axis within the first accommodation portion; and

a digital image capturing unit provided on a circuit board, the digital image capturing unit disposed along the optical axis and spaced from the optical element to define an optical path therebetween;

wherein the circuit board is disposed within the second accommodation portion,

wherein the housing is formed from a unitary first part consisting of plastic and a second part consisting of a vapor resistant material, the second part radially surrounding a portion of the optical path about the optical axis such that penetration of vapor into the optical path disposed between the optical element and the digital image capturing unit is prevented, and

wherein the second part of the housing consisting of a vapor resistant material radially surrounds at least a portion of the optical element in an overlapping manner about the optical axis at least partly in an axial direction.

20. The camera according to claim 19, wherein the second part is at least partially embedded within the first part.

21. The camera according to claim 19, wherein the second part is made of one of aluminum, zinc, magnesium, copper, and brass.

22. The camera according to claim 19, wherein the second part is one of a die-cast part and a continuous casting part.

23. The camera according to claim 19, wherein the optical element is screwed into the first accommodation portion via a thread.

24. The camera according to claim 19, wherein the first accommodation portion and/or the second accommodation portion is formed by the first part.

25. The camera according to claim 19, wherein the first accommodation portion and/or the second accommodation portion is formed by the second part.

26. The camera according to claim 19, wherein the first accommodation portion is cylindrically formed with a first diameter and/or the second accommodation portion is cylindrically formed with a second diameter, the first diameter being smaller than the second diameter.

27. The camera according to claim 19, wherein the second part is radially inwardly disposed with respect to the first part, or the second part is radially outwardly disposed with respect to the first part.

28. The camera according to claim 19, wherein the housing further comprises a connection portion configured to mount the housing on a vehicle.
