Abstract
This invention provides the combined driving spring in the slide cover hinge of the mobile communication terminal. It comprises multiple springs in the same shape, the multiple springs are arranged and combined in turn on the same plane, with their both ends fixed; the driving spring is provided with connections on its both ends to match with the slide in the slide hinge. The shape of the spring is similar to the shape W. The driving spring provided by this invention can be directly used as a driving mechanism in the slide hinge for the mobile communication terminals, simplifying the structure of the driving mechanism. In particular, when the spring in the shape of W is employed, the spring can not only facilitate the combination connection, but also provide a greater force. Besides, when the slide cover slides, less area is occupied when the spring deforms, making it easier to arrange other parts of the mobiles device.
