Description

Portable Terminal Having Unified Damping Structure

The present invention relates to a portable terminal, and more particularly, to a portable terminal having an integrated damping structure that can be applied to the damping structure of a foldable portable terminal.

Portable terminals such as mobile phones and PDAs (Personal Digital Assistants) have a bar type, a flip type, a folder type, a slide type and a slide and swing type ( slide and swing type).

The folder type has a structure in which the main body portion and the folder portion are connected through a hinge and opened and closed in a manner in which the folder portion rotates by a predetermined angle with respect to the main body portion by an external force.

Folder type portable terminals have a smaller size than other types of portable terminals when the folder is closed, such as when carrying, and larger sizes than other types of portable terminals when the folder is opened, such as when the portable terminal is used. There is an advantage that it is convenient to use because the folder is in close contact with the side of the human face by the opening angle.

In a general portable terminal of a folder type, the hinge connecting the main body and the folder is automatically opened without an external force from the predetermined angle to the maximum rotation angle when the folder rotates by a external force based on a predetermined angle. When the part is fully opened, that is, when it closes to a predetermined angle preset by an external force at the maximum rotation angle, it has a semi-automatic opening and closing function to automatically close without being subject to external force.

When the folder type is closed due to the semi-automatic opening and closing function as described above, the folder type portable terminal collides with each other and the impact amount due to the collision is transmitted to the components installed inside the body part and the folder part. The durability of the terminal is reduced.
