Abstract

The present disclosure provides a camera module for use in a portable electronic device. The camera module comprises a shiftable lens barrel comprising an objective assembly holding coaxially one or more lens elements defining an optical axis. The camera module has a retractable cover window. The lens barrel has an operative state and a collapsed state and the cover window has a corresponding extended and retracted position. The camera further comprises an actuator including a driving motor; a pop-out assembly actuatable by the actuator. The pop-out assembly includes a driving cam configured to be driven rotationally by the actuator, a carrier configured to receive the lens barrel and an image sensor configured to image a field of view of the objective assembly when the lens barrel is in the operative state.

First claim

What is claimed is:

1 . A camera module for use in a portable electronic device, the camera module comprising:
a lens barrel comprising an objective assembly holding coaxially one or more lens elements defining an optical axis, the lens barrel being configured to be axially movable between an operative state and a collapsed state; a cover window arranged over the lens barrel and configured to be axially movable between a retracted position and an extended position; an actuator including a driving motor; a cover window pop-out assembly actuatable by the actuator, the cover window pop-out assembly including a driving cam configured to be driven rotationally by the driving motor, the driving cam being coupled to the cover window so that a rotation of the driving cam causes the cover window to axially move between the retracted position and the extended position; a barrel pop-out assembly including a magnet and a coil, the barrel pop-out assembly configured to use the magnet and the coil to cause the lens barrel to axially move from the collapsed state to the operative state when the cover window pop moves from the retracted position into the extended position; an image sensor configured to image a field of view of the objective assembly when the lens barrel is in the operative state.

2 . The camera module of claim 1 , wherein the cover window is configured so as to push the lens barrel into the collapsed state when the lens barrel is in the operative state and wherein the cover window is operated by the cover window pop-out assembly to move from the extended position to the retracted position.

3 . The camera module of claim 1 , wherein the barrel pop-out assembly and the cover window pop-out assembly are coordinated.

4 . The camera module of claim 1 , further comprising a protective seal configured to maintain impermeability of camera module.

5 . The camera module of claim 1 , further comprising a back housing configured for accommodating camera module, and a front housing configured to maintain axially the driving cam on the back housing while allowing rotation of the driving cam.

6 . The camera module of claim 5 , further comprising a front ball bearing coupling between the front housing and to the driving cam, and/or a back ball bearing between the driving cam and the back housing.

7 . The camera module of claim 5 , further comprising one or more static lens elements arranged to be static relative to the back housing.

8 . The camera module of claim 1 , wherein the actuator further comprises:
a worm screw configured to be powered by the driving motor; a worm wheel coupled the worm screw and to the driving cam so that a rotation of the worm screw rotates the driving cam.

9 . The camera module of claim 8 , wherein the driving cam and the worm wheel are friction coupled, the coupling being configured to be overcome when a collapsing force larger than a predefined threshold is applied.

10 . The camera module of claim 1 , the cover window pop-out assembly including one or more springs, and wherein the one or more springs act as shock absorber for the camera when the portable electronic device is dropped.

11 . The camera module of claim 1 , wherein the barrel pop-out assembly is configured to cause the lens barrel to axially move for focusing.

12 . The camera module of claim 1 , wherein the image sensor is moved to perform optical image stabilization.

13 . The camera module of claim 1 , wherein a difference in a height of the camera nodule between the extended state and the collapsed state is larger than 1 mm.

14 . The camera module of claim 1 , wherein a difference in a height of the camera module between the extended state and the collapsed state is larger than 10%.

15 . The camera module of claim 1 , wherein a diameter of the cover window may be between 5 and 40 mm.

16 . The camera module of claim 1 , wherein a height of the camera module in the collapsed state is between 6 and 18 mm.

17 . The camera module of claim 1 , wherein a height of the camera module in the operative state is between 7 and 30 mm.

18 . The camera module of claim 1 , wherein the cover window is configured so as to provide an axial gap between the lens barrel in the operative state and the cover window in the extended position.

19 . The camera module of claim 18 , wherein the axial gap is in a range of 0.1 mm-3 mm.

20 . The camera module of claim 1 , wherein the portable electronic device is a smartphone.
