Wiping apparatus for camera and control method therefor

1 . A wiping apparatus for a camera, comprising:

a housing in which a driving part is configured to be mounted;

a rotation part that rotates by being engaged with a worm gear, which is coupled to a first rotation axis of the driving part;

a conversion part that is engaged with the rotation part and configured to move in a linear reciprocating motion along a length direction of the rotation part within the housing in response to a rotational motion of the rotation part; and

a cleaning part that extends from the conversion part to an outside of the housing, wherein the cleaning part wipes a surface of a protective cover, which is provided in front of a lens of a camera module.

2 . The wiping apparatus of claim 1 , wherein the rotation part comprises:

a worm wheel, which rotates about a second rotation axis that is not parallel to the first rotation axis of the worm gear; and

a screw shaft, which includes the worm wheel disposed at a proximal end portion thereof and includes a first gear formed on an outer circumferential surface thereof where the worm wheel is not disposed.

3 . The wiping apparatus of claim 2 , wherein the conversion part comprises:

a transfer member, which includes a second gear formed on an inner circumferential surface thereof to engage with the first gear; and

an extension member, which extends from the transfer member to be at least partially exposed on the outside of the housing.

4 . The wiping apparatus of claim 3 , wherein the cleaning part comprises:

an arm member, which has a proximal end bent at a distal end of the extension member to correspond to the protective cover and has a length corresponding to a height or width of the protective cover;

a blade, which is detachably mounted in the arm member by being inserted from a front of the arm member and protrudes at least partially to a rear of the arm member facing the surface of the protective cover; and

a rotary cover, which is rotatably coupled to the arm member to cover the front of the arm member.

5 . The wiping apparatus of claim 4 , wherein the arm member comprises:

a mounting hole, which is formed to allow the blade to be inserted thereinto; and

steps, which are configured to be interfered with the blade in a direction of coupling of the blade to prevent the blade from passing through the mounting hole.

6 . The wiping apparatus of claim 5 , wherein the blade comprises:

an elastic piece, which is configured to elastically contact the surface of the protective cover when inserted into the mounting hole; and

a mounting piece, which is integrally formed with the elastic piece and is installed inside the mounting hole by abutting the steps.

7 . The wiping apparatus of claim 5 , wherein the arm member further comprises:

protrusion pieces, which protrude from either side of a proximal end of the arm member and selectively interfere with first coupling holes formed on either side of a proximal end of the rotary cover; and

support pieces, which protrude from either side of a distal end of the arm member and form a rotation axis by being inserted into second coupling holes formed on either side of a distal end of the rotary cover.

8 . The wiping apparatus of claim 3 , wherein the extension member comprises an aperture formed on one side thereof adjacent to the transfer member, and

wherein the conversion part includes a guide member, which is disposed parallel to the screw shaft inside the housing and guides the linear reciprocating motion of the extension member.

9 . The wiping apparatus of claim 1 , further comprising:

a cover coupled on the housing to cover the rotation part, a transfer part of the conversion part, and the driving part; and

a washer fluid injection module coupled to the outside of the housing, which is configured to spray cleaning fluid toward the surface of the protective cover.
