Description

  The present invention relates to a hinge device, and more particularly, to a hinge device in which a newly designed sleeve and a restricting means are connected to each other to prevent wear during rotation.

  Mobile phones are required to be lightweight, thin, compact, and easy to carry, and are often carried in clothing pockets or suitcases. However, since the key of the mobile phone is usually provided on the mobile phone main body, erroneous dialing due to erroneous contact is likely to occur, which creates unnecessary costs and problems. Manufacturers have designed a code lock function on the key to solve this problem, but this is rather inconvenient for operation.

  For this reason, a mobile phone with a modified cover appears, and a hinge device is provided between the mobile phone body and the cover to open and close the cover. 2. Description of the Related Art A well-known hinge device for a mobile phone is disclosed in, for example, Patent Document 1. This hinge device includes a case, and a shaft rod, a cam, an elastic means, and a rotating shaft seal are provided inside the case. A groove is provided to control the rotation angle of the shaft and the cam. However, in this structure, a guide cutout and a groove must be formed in the case, and in consideration of the strength of the case, the case wall surface cannot be thinly cut, and the overall volume is relatively large. Patent Document 2 describes a cylindrical case, in which a rod, a shaft, a cam structure and elastic means are provided, and it is necessary to separately combine a washer, a screw, and an O-ring, and the rod is driven by the shaft, and Drive and rotate the cam structure. The components of this structure are complicated, and when applied to a mobile phone, a pair of hinge structures must be installed, and the whole volume cannot be made compact. In order to solve the above-mentioned drawbacks of the structure, in Patent Document 3, the opening and closing of the cover is controlled by using the first cam, the second cam, the guide means, the elastic means, and the expansion / contraction means. Although this structure can greatly reduce the volume of the hinge structure, since there is no case outside the structure, positioning and assembling are difficult, and the overall structural strength is not high, and the service life is shortened.
