The present invention relates to a doorbell device.
A doorbell device is a device with which a visitor informs somebody indoors of his/her visit using voice or video. A camera may be installed in the doorbell device to make it possible to check the surrounding environment of an entrance door from indoors using the video when the visitor rings a bell.
In general, in a doorbell device, a body including the bell in addition to the camera is coupled to a wall surface near the door using a bracket. In this case, because the camera is fixed to the body when installed, a viewing angle of the camera is fixed. Thus, according to an installation environment of the doorbell device, there is a blind spot of which video information cannot be acquired using the camera. When the visitor is in the blind spot, it is difficult to identify the visitor.
The present invention is directed to providing a doorbell device capable of changing a viewing angle of a camera.
The problem to be solved is not limited to the above-described problem, and other unmentioned problems will be clearly understood by those skilled in the art from the following description.
One aspect of the present invention provides a doorbell device including: a bracket including a fixed surface coupled to a support structure; a viewing angle-adjusting bracket rotatably coupled to the bracket and including a front surface inclined with respect to the fixed surface; and a doorbell body coupled to the viewing angle-adjusting bracket and including a camera having an optical axis inclined with respect to an axis center of the viewing angle-adjusting bracket.
The bracket and the viewing angle-adjusting bracket may be disposed to rotate about a concentric axis.
A length of a top surface of the viewing angle-adjusting bracket and a length of a bottom surface thereof may be different from each other.
Another aspect of the present invention provides a doorbell device including: a bracket including a fixed surface coupled to a support structure; a viewing angle-adjusting bracket coupled to the bracket and including a front surface inclined with respect to the fixed surface; and a doorbell body including a body coupled to the bracket and a rotation block, the rotation block including a camera which is rotatably coupled to the body and including an inclined contact surface in contact with the front surface.
The camera may be installed on the rotation block so that an optical axis of the camera is inclined with respect to an axis center of the rotation block.
The bracket may include a driving unit connected to the rotation block and configured to rotate the rotation block.
The driving unit may include a motor, and an axis center of the motor may be perpendicular to the front surface.
The doorbell device may further include a controller configured to control the driving unit.
According to an embodiment, a viewing angle-adjusting bracket is rotatably coupled to a bracket, and a fixed surface on which a doorbell body is mounted is obliquely disposed so that a viewing angle of a camera can be arbitrarily changed by a user and thus a visitor's identifiability can be improved.

Objectives, specific advantages, and new features of the present invention will become more apparent from the following detailed description and exemplary embodiments involved in the attached drawings. Terminology or terms used in the present specification and the claims should not be interpreted to being limited in a general or dictionary sense but should be interpreted in a sense and a concept that comply with the technical spirit of the invention based on a principle that the inventor can properly define the concept of the term so as to describe his/her own invention in a best manner. In the description of the invention, a detailed description of a related, commonly-used technology that may unnecessarily obscure the subject matter of the invention is omitted.

The bracket 110 is coupled to a wall surface on which a door is formed, so as to fix the viewing angle-adjusting bracket 120 or the doorbell body 130 to a wall surface 1. The appearance of the bracket 110 may be embodied in various shapes, such as a circular shape, an oval shape, and a square shape, to correspond to the shape of the doorbell body 130. A fastening hole, through which the bracket 110 is coupled to the viewing angle-adjusting bracket 120 or the doorbell body 130, may be provided in the bracket 110.
Meanwhile, referring to
Also, the mechanism connector 113 may be disposed in the center of the bracket 110 so as to fix the doorbell body 130 without limiting an angle.

For example, when a length of a top surface 122 of the viewing angle-adjusting bracket 120 is L1 and a length of a bottom surface 123 of the viewing angle-adjusting bracket 120 is L2, L1 may be smaller than L2. The viewing angle-adjusting bracket 120 may have a trapezoidal shape overall when viewed from a lateral direction. The slanted front surface 121 is provided to acquire a tilting angle of the camera.

The doorbell body 130 may be coupled to the viewing angle-adjusting bracket 120.
The doorbell body 130 may include a camera 131. The camera 131 may acquire video information on the front of a door to provide the acquired video information to a user through a separate indoor display device.
In this case, the camera 131 may be installed in the center of the doorbell body 130 so that an optical axis O of the camera 131 is inclined with respect to the concentric axis LC. In this case, an angle T between the concentric axis LC and the optical axis O may be defined as a tilting angle T of the camera 131.

The doorbell body 130 may include a camera 131, a body 133, and the rotation block 134. The body 133 is coupled to the bracket 110, and the rotation block 134 is rotatably coupled to the viewing angle-adjusting bracket 120. In detail, the rotation block 134 is coupled to the body 133 and the viewing angle-adjusting bracket 120, respectively, so as to be rotatable about the concentric axis CL of the viewing angle-adjusting bracket 120.
When the rotation block 134 is rotated, the optical axis O is changed due to the angle T between the concentric axis LC and the optical axis O such that the viewing angle of the camera 131 is changed.

In this case, an optical axis O may be inclined with respect to the axis center S1. A rotation shaft 140 may be provided in a viewing angle-adjusting bracket 120. The rotation shaft 140 is coupled to the rotation block 134. Thus, the rotation block 134 is rotated when the rotation shaft 140 is used as an axis center, in a state in which the rotation block 134 is in contact with a slanted front surface 121 of the viewing angle-adjusting bracket 120. In this case, the rotation block 134 may have a cylindrical shape, a guide protrusion 134a may protrude from an outer circumferential surface of the rotation block 134, a cylindrical hole into which the rotation block 134 is inserted may be formed in the body 133, and a guide slot 133a into which the guide protrusion 134a is inserted may be formed on an inner circumferential surface of the cylindrical hole.
When the rotation block 134 is rotated, the position of the optical axis O is changed due to an angle T between the axis center S1 and the optical axis O such that the viewing angle of a camera 131 is changed.

A rotation angle of the driving unit 150 may be controlled by a controller 160. The controller 160 may be configured to control driving of the motor of the driving unit 150 based on a user's manipulation signal or a signal sensed through an additional sensor.

For example, when a length of a top surface 136 of the doorbell body 130 is L3 and a length of a bottom surface 137 of the doorbell body 130 is L4, L3 may be smaller than L4.
