Example Embodiment

[0043] Hereinafter, preferred embodiments for implementing the present invention will be described with reference to the drawings.

[0044] 1 to 11 show a mobile phone 1 using the hinge device 10 of the present invention. The mobile phone 1 includes a call side frame 2 and a receiving side frame 3. One end of the call-side housing 2 and one end of the answering-side housing 3 are connected by a hinge device 10 so as to be rotatable.

[0045] The call side frame 2 is composed of two half bodies 2A and 2B, and is formed in a relatively thin rectangular parallelepiped shape. As shown in FIGS. 8 to 11, a fitting recess 2b is formed at one end portion in the longitudinal direction of the front surface 2a of the call side housing 2. The receiving side frame 3 is composed of two half bodies 3A and 3B, and is formed in a relatively thin rectangular parallelepiped shape. The top view shape of the answering side frame 3 and the top view shape of the call side frame 2 are formed substantiall...

Abstract

The present invention provides a biaxial hinge device which is manufactured cheaply. Setting a first and a second rotational component (22, 23) on the hinge main body which rotate surrounding a first and a second rotational axes (01, 02) paralleling to each other separately. Connecting one end of a connecting bar (34) to the first rotational component (22), the connecting bar (34) rotates surrounding a third rotational axes (03) which is parallel to the first and the second rotational axes (01, 02); the other end of the connecting bar (34) connects to the second rotational component (23) and rotates surrounding a fourth rotational axes (04) which is parallel to the first and the second rotational axes (01, 02). The third and the fourth rotational axes (03, 04) are configured on the opposite side of the line which passes through the first and the second rotational axes (01, 02).

Description

technical field [0001] The invention relates to a biaxial hinge device suitable for portable devices such as game machines and mobile phones. Background technique [0002] Generally speaking, a biaxial hinge device includes: a hinge main body; first and second rotating parts, which are arranged to be able to rotate around the first and second rotating axes parallel to the hinge main body; the first and second rotating parts Two gears are respectively arranged on the first and second rotating parts and cannot rotate. The first and second gears mesh with each other. In this way, the first and second rotating parts rotate in a mutually interlocking state. [0003] But when using the first and second gears to connect the first and second rotating parts with each other, only the backlash between the first and second gear tooth surfaces will make the first and second rotating parts There is a problem of looseness in the circumferential direction. This is when the two-axis hing...
