Camera assembly and assembling method thereof

A camera assembly comprising:

• a motor configured to generate a driving power;
• a motor shaft that extends from the motor, such as to define a first axis, and is configured to rotate by the driving power of the motor;
• a pulley configured to rotate on a second axis, that is spaced from the first axis, according to rotation of the motor shaft;
• a belt configured to couple the motor shaft and the pulley, and convert the rotation of the motor shaft to rotation of the pulley;
• a camera module configured to be mounted on the pulley and rotate together with the pulley;
• and
• an elastic body configured to apply a biasing force to the motor shaft such as to bias the motor shaft in a direction away from the second axis;
• a housing;
• a base fixed on the housing;
• a movable body fixedly coupled to the motor and rotatably coupled to the base;
• and
• a fastener configured to fixedly couple the motor and the movable body,
• wherein a head of the fastener is received in a through hole with a clearance, such as to allow a contact between the base and the movable body without interrupting turning motion of the movable body with respect to the base, and
• wherein the camera assembly further comprises:
• a fixed shaft configured to rotatably mount the movable body on a first point of the base;
• and
• a movable shaft configured to be coupled to one from among the base and the movable body at a second point, that is spaced from the first point, the movable shaft received in a corresponding slot in the other from among the base and the movable body such as to support sliding motion of the movable body.

A method for assembling a camera assembly, the method comprising:

• fixedly coupling a motor to a movable body;
• rotatably coupling the movable body to a base;
• installing an elastic body such that two ends of the elastic body are interposed between the movable body and the base;
• fixedly mounting the base on a housing;
• coupling, using a timing belt, a motor shaft to a pulley, the motor shaft extending from the motor and passing through a hollow of the movable body and a hollow of the base, and the pulley having a camera module mounted thereon;
• providing a fixed shaft that rotatably mounts the movable body on a first point of the base;
• and
• coupling at least one movable shaft to one from among the base and the movable body at a respective second point, that is spaced from the first point, and providing each of the at least one movable shaft in a corresponding slot in the other from among the base and the movable body such as to support sliding motion of the movable body,
• wherein the fixedly coupling comprises fixedly coupling the motor and the movable body with a fastener, a head of the fastener received in a through hole with a clearance such as to allow a contact between the base and the movable body without interrupting turning motion of the movable body with respect to the base.
