`
`[54] Title of the Utility Model: DOUBLE HINGE DEVICE
`[57] Abstract
`
`The present utility model provides a double hinge structure for
`an electronic product having a liftable cover (such as a
`notebook computer, a portable video player, a mobile phone,
`a personal digital assistant, or a digital camera having a
`liftable screen). The structure enables the electronic product
`having a liftable cover to be equipped with an advantageous
`360-degree rotating function, which is a function that all
`existing electronic products having liftable covers (the general
`design enables a rotation by 180 degrees at most) are unable
`to achieve. Because of the 360-degree rotating function, these
`electronic products having liftable covers have the following
`advantages: the viewing angle is more adaptable; any surface
`may serve as a support, which provides the most space-saving
`viewing mode; and when a display screen is completely
`flipped to the other side (rotating by 360 degrees), a user may
`freely change the cover surface at any time and the key
`operating surface may still be used.
