Abstract

A housing of an imaging unit is disclosed. The housing comprises an outer surface and an inner surface, wherein the inner surface of the housing defines a lens channel sized to receive a lens barrel. Further, the inner surface of the housing defines a helical step in the lens channel, wherein the helical step protrudes outwardly into the lens channel, and wherein the helical step is angled at a first predetermined pitch. Further, the inner surface of the lens channel defines a glue pocket, in the lens channel, which extends from the inner surface of the housing to the outer surface of the housing such that a first edge surface, defining a portion of a periphery of the glue pocket, is coplanar with the helical step.

First claim

What is claimed is:

1. An image capturing device comprising:
an imaging unit comprising:
a housing that comprises an inner surface, wherein the inner surface of the housing defines a lens channel, wherein the inner surface of the lens channel defines:
a helical step that protrudes outwardly from the inner surface into the lens channel, wherein the helical step is angled at a first predetermined pitch, and
a glue pocket, in the lens channel, which extends from the inner surface of the lens channel to an outer surface of the housing such that a first edge surface, defining a portion of a periphery of the glue pocket, is parallel with a portion of the helical step; and

a lens barrel received in the lens channel, the lens barrel comprising an outer surface that defines:
a cam that protrudes from the outer surface of the lens barrel, wherein the cam abuts the helical step, and
a helical rib that protrudes from the outer surface of the lens barrel, wherein the helical rib is angled at a second predetermined pitch, wherein the first predetermined pitch of the helical step is the same as the second predetermined pitch of the helical rib.

2. The image capturing device of claim 1 , wherein the housing further comprises a second edge surface, a third edge surface, and a fourth edge surface, wherein the first edge surface, the second edge surface, the third edge surface, and the fourth edge surface define the periphery of the glue pocket, and wherein the second edge surface is parallel to the first edge surface.

3. The image capturing device of claim 2 , wherein a portion of the helical rib extends out from the second edge surface, defining the portion of the periphery of the glue pocket.

4. The image capturing device of claim 2 , wherein a distance between the first edge surface of the glue pocket and an edge of the helical rib remains constant as the cam slides over the helical step to adjust a position of the lens barrel in the lens channel.

5. The image capturing device of claim 2 , wherein a distance between the second edge surface of the glue pocket and an edge of the helical rib remains constant as the cam slides over the helical step to adjust a position of the lens barrel in the lens channel.

6. The image capturing device of claim 2 , wherein glue is disposed between the edge of the helical rib and the first edge surface, defining the periphery of the glue pocket.

7. The image capturing device of claim 1 , wherein the first edge surface of the glue pocket, the helical rib, and the helical step are parallel to each other.

8. The image capturing device of claim 1 , wherein the housing has a scan window end portion, and a sensor end portion spaced apart from the scan window end portion along a lateral axis perpendicular to a longitudinal axis of the housing.

9. The image capturing device of claim 1 , wherein the cam has a first end and a second end, wherein the first end of the cam abuts the helical step.

10. The image capturing device of claim 9 , wherein the helical rib intersects with the cam at the first end of the cam.

11. A housing of an imaging unit, the housing comprising:
an outer surface and an inner surface, wherein the inner surface of the housing defines:
a lens channel sized to receive a lens barrel,
a helical step in the lens channel, wherein the helical step protrudes outwardly into the lens channel, and wherein the helical step is angled at a first predetermined pitch, and
a glue pocket, in the lens channel, which extends from the inner surface of the lens channel to the outer surface of the housing such that a first edge surface, defining a portion of a periphery of the glue pocket, is parallel with a portion of the helical ramp.

12. The housing of claim 11 , wherein the helical step, defined in the lens channel, is configured to slidably abut a cam defined on an outer surface of the lens barrel, in an instance in which the lens barrel is received in the lens channel.

13. The housing of claim 11 , wherein a portion of a helical rib defined on the lens barrel extends out from a second edge surface of the glue pocket, in an instance in which the lens barrel is received in the lens channel.

14. The housing of claim 13 , wherein a distance between the first edge surface, defining a portion of the periphery of the glue pocket, and an edge of the helical rib remains constant, as a position of the lens barrel in the lens channel is adjusted by sliding the lens barrel on the helical step.

15. The housing of claim 13 , wherein the helical rib on the lens barrel is angled at a second predetermined pitch, wherein the second predetermined pitch is same as the first predetermined pitch of the helical step.

16. The housing of claim 15 further comprising an image sensor disposed at the sensor end portion of the housing.

17. The housing of claim 15 further comprising a scan window disposed at the scan window end portion of the housing.

18. The housing of claim 11 , wherein the housing has a scan window end portion, and a sensor end portion spaced apart from the scan window end portion along a lateral axis of the housing.

19. The housing of claim 11 , wherein the housing further comprises a second edge surface, a third edge surface, and a fourth edge surface, wherein the first edge surface, the second edge surface, the third edge surface, and the fourth edge surface define the periphery of the glue pocket, and wherein the second edge surface is parallel to the first edge surface.
