Embodiment Construction

[0033] Refer below Figure 1 to Figure 17 An embodiment in which the hub device of the present invention is used in a mobile phone will be described. In addition, the hinge device of the present invention can be used between a device body and a cover that are mutually rotatable between a closed position and an open position, other than a mobile phone.

[0034] An embodiment of the first aspect of the invention is shown in Figure 1 ~ Figure 1 2. FIG. 12 is a diagram showing a mobile phone using the hub device 1 of the present invention. The mobile phone includes a transmitting unit (equipment body) A provided with a microphone, various operation buttons (not shown in the figure), etc., a receiver provided with a speaker (not shown in the figure) and a liquid crystal display unit C, etc. The talking part B, the talking part A and the talking part B are connected through the hinge device 1, and can rotate around the rotation axis L.

Abstract

A hinge device in which contact protrusions (54, 54) of a resin driving part (not shown) are inserted into both ends of a keyway (41) in the circumferential direction of a metal rotating part (4). A key portion (B3) for accommodating the cylindrical portion is inserted between the contact protrusions (54, 54). The circumferential interval between the contact protrusions (54, 54) is slightly wider than the width of the key portion (B3). As a result, when the speaking part is turned to the open position or the closed position, the contact protrusions (54, 54) and the key part (B3) collide with each other to produce a snapping sound. And since both the contact protrusions (54, 54) and the key portion (B3) are made of resin, early wear of the key portion (B3) can be prevented.

Description

technical field [0001] The present invention relates to a hinge device for mobile phones and the like, which can generate snapping sounds in the closed position and the open position. Background technique [0002] A hinge device generally used in a mobile phone or the like has a hinge main body and a rotating member. The hinge main body and the rotating part are respectively non-rotatably connected to the transmitting part and the receiving part. But the hinge main body and the rotating part are rotatably connected to each other. Thus, the transmitting part and the receiving part of the mobile phone are connected through the hinge device and can be rotated. [0003] The rotating part is in contact with the hinge main body through a force applying device such as a coil spring. Fig. 18(A) and Fig. 19(A) respectively show the contact surfaces of the hinge main body a and the rotating part b. On the contact surface of the hinge main body a, three fitting recesses a1, a2, a3 ...
