This is a U.S. national stage application of PCT Application No. PCT/CN/2008/071367 under 35 U.S.C. 371, filed Jun. 19, 2008 and published in Chinese, which claims the priority benefit of Chinese Application No. 200820085195.4, filed Apr. 3, 2008.

TECHNICAL FIELD

This invention involves the driving mechanism in the slide cover hinge of the mobile communication terminal.

BACKGROUND

At present, the slide cover hinge structure is very popular among the mobile communication terminals such as mobile phone and PHS (personal Handy-phone System), whose upper cover and lower cover are connected by the hinge. The semi-automatic slide cover hinge is a common hinge used for the slide cover connection structure, which is provided with a driving mechanism for the slide cover. It is always the case that the driving spring is used as the driving part in such mechanism. When the operator pushes the slide cover, the driving spring saves the energy produced by the deformation area such as stretching, compression or torsion. When the operator pushes the slide cover beyond the critical point, that is, after the spring is converted from the energy saving to the energy release, the slide, driven by the spring, can slide on. The existing driving mechanism provided with compression spring and tension spring has a problem of being complicated in structure.

SUMMARY OF INVENTION

The technical issue to be settled by this invention is to provide a combined driving spring in the slide cover hinge of the mobile communication terminals which can simplify the structure of the driving mechanism. For this purpose, this invention adopts the following technical schemes: it comprises multiple springs in the same shape, the said multiple springs are arranged and combined on the same plane in turn, with both ends fixed; the said driving spring is provided with connections on its both ends to match with the slide in the slide cover hinge.

The shape of the said spring is similar to the shape W.

With the technical scheme of this utility model employed, the driving spring provided by this invention can be directly used as the driving mechanism in the slide cover hinge of the mobile communication terminal, simplifying the structure of the driving structure. 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.

EMBODIMENT

Refer to the figures attached. This invention comprises multiple springs in the same shape. Four springs are provided in this embodiment, whose mark numbers in the figures are respectively 11, 12, 13 and 14. Other number of springs may be provided as required in practice. The springs in this embodiment are the W-shaped springs.

The said multiple springs are arranged and combined on the same plane in turn, with their both ends fixed. The said fixation can be the direct fixation among the springs, for example by welding; or the both ends of the springs are fixed on connecting piece to achieve the said fixation; or both the above-mentioned modes are adopted at the same time.

In this embodiment, the both ends of the said driving spring are provided with the connections to match with the slide in the slide cover hinge, with the springs bent into circle-shaped hook 15 at the connection, and as shown in the figures, the circle-shaped hook 15 at the end of the springs 11,12,13 and 14 are nested in turn, and their inner bores can be connected with the rivet 18 on the slide in the slide cover hinge to achieve the connection of the driving mechanism with the slide.

The connector 16 with hole may also be fixed at the said connection. The said connector 16 assumes a shape of step with its top extending outward 17. The thinner part of the connector 16 is inserted into the inner hole on the end of spring for fixing. At this time, what is connected with the rivet 18 is the connector 16. The top of the connector 16 extends outward 17 and extends outward 17 can also be fixed together with circle-shaped hook 15 on the end of the spring, thus playing a role of the connecting piece as mentioned above.

The cross-sections of the said spring 11, 12, 13 and 14 assume rectangles for easy assembly and fixation. Of course, the shape of the cross-section may be circle.

Referring to FIG. 6, the said springs 11, 12, 13 and 14 may be fixed in other ways: their two ends are fixed on the connecting piece 16a by inlay injection or metal sheet welding. The said connecting piece is provided with the said connection. Such connection is the connecting hole 16b.

In addition, the said driving spring may be connected with clamping pieces on its both ends. The said clamping piece is provided with the said connection. The springs 11, 12, 13 and 14 are fixed by connecting with the clamping piece.

The mark numbers 100a and 200a in the figure respectively denote the states of the driving mechanism when the slide arrives at two movement limit positions. The mark number 300a in the figure denotes the intermediate state of the above-mentioned two states. The mark numbers 3 and 4 in the figure respectively denote the upper slide and lower slide in the slide cover hinge connected by the driving spring.
