Abstract

According to an embodiment of the present invention, disclosed is a camera device comprising: a housing; a lens assembly including at least one lens; a driving unit for moving the lens assembly; a main substrate on which an image sensor is provided; and a first substrate and a second substrate electrically connected to the driving unit and arranged on facing side surfaces of the housing to be spaced apart from each other, wherein the main substrate includes a first connection member connected to the first substrate and a second connection member connected to the second substrate.

First claim

1 . A camera device comprising:
a housing; a lens assembly including at least one lens; a driving unit configured to move the lens assembly; a main substrate on which an image sensor is provided; and a first substrate and a second substrate electrically connected to the driving unit and spaced apart from each other on opposite side surfaces of the housing, wherein the main substrate includes a first connection member connected to the first substrate and a second connection member connected to the second substrate.

2 . The camera device of claim 1 , wherein the driving unit includes a driving coil and a driving magnet positioned to face the driving coil,
the driving coil includes a first coil disposed on a first side surface of the housing, and a second coil disposed on a second side surface of the housing, and the driving magnet includes a first magnet corresponding to the first coil, and a second magnet corresponding to the second coil.

3 . The camera device of claim 2 , comprising:
a driving driver disposed on the main substrate, wherein the driving driver is electrically connected to the first coil and the second coil.

4 . The camera device of claim 3 , comprising:
a base unit surrounding the image sensor and the driving driver on the main substrate.

5 . The camera device of claim 1 , wherein the first substrate includes a first main area and a first connection area in contact with an end of the first main area, and
the second substrate includes a second main area and a second connection area in contact with an end of the second main area.

6 . The camera device of claim 5 , wherein the first connection area is inclined inward with respect to the first main area,
the second connection area is inclined inward with respect to the second main area, and a first separation distance between the first main area and the second main area is greater than a second separation distance between the first connection area and the second connection area.

7 . The camera device of claim 5 , wherein the first connection area includes a first connection terminal part disposed on an outer surface, and
the second connection area includes a second connection terminal part disposed on an outer surface.

8 . The camera device of claim 7 , wherein the main substrate includes a first substrate terminal part and a second substrate terminal part which are disposed on an upper surface thereof,
the first connection area overlaps with the first substrate terminal part, and the second connection area overlaps with the second substrate terminal part.

9 . The camera device of claim 8 , wherein the first connection member is disposed between the first connection terminal part and the first substrate terminal part, and
the second connection member is disposed between the second connection terminal part and the second substrate terminal part.

10 . The camera device of claim 1 , wherein the lens assembly includes:
a second lens assembly; and a first lens assembly disposed between the second lens assembly and the image sensor, and a first movement distance of the first lens assembly is greater than a second movement distance of the second lens assembly.

11 . The camera device of claim 1 , wherein the first connection member and the second connection member include a conductive member.

12 . A camera device comprising:
a housing; a lens assembly including at least one lens; a driving unit configured to move the lens assembly; a main substrate on which an image sensor is provided; a first substrate and a second substrate electrically connected to the main substrate; and a driving driver disposed on the main substrate, wherein the first substrate is disposed on a first side surface of the housing, and the second substrate is disposed on a second side surface opposite to the first side surface, and the driving driver is electrically connected to the driving unit.

13 . The camera device of claim 12 , wherein the lens assembly includes a first lens assembly and a second lens assembly,
the driving unit includes a first magnet disposed on one of the first lens assembly and the first substrate, and a first coil disposed on the other one of the first lens assembly and the first substrate, and the driving unit includes a second magnet disposed on one of the second lens assembly and the second substrate, and a second coil disposed on the other one of the second lens assembly and the second substrate.

14 . The camera device of claim 13 , wherein a first movement distance of the first lens assembly is greater than a second movement distance of the second lens assembly.

15 . The camera device of claim 13 , wherein the driving driver is located in a region between the first substrate and the second substrate.
