Problems solved by technology

[0010] However, the housing and the hinge are generally formed as moldings made of, for example, plastic, and their sizes vary, and it is difficult to reduce the clearance in consideration of productivity.
[0011] In addition, if the hinge top and the housing support portion are made to interfere with each other (for example, making the gap equal to or less than 0 as in the case of press fit), both are scratched when assembled, resulting in poor productivity of the assembly line. Difference
Also, when disassembled for maintenance purposes and then reassembled, the gap is changed, increasing the rattling sound
[0012] That is, attempts to reduce the rattling sound by using a conventional free-stop type hinge unit resulted in poor productivity of the assembly line or insufficient reusability of the hinge unit

[0044] A first embodiment that suitably implements the present invention will be described.

[0045] FIG. 2 shows the construction of a mobile phone terminal according to the present invention. The mobile phone terminal according to the present embodiment has a housing on the display side 1 and a housing on the operation side 2 .

[0046] As shown in FIG. 3 , the housing on the display side 1 and the housing on the operation side 2 are rotatably connected to each other by a hinge unit 3 . Further, between the housing on the display side 1 and the housing on the operation side 2, a dummy hinge 4 for guiding cables or the like electrically connecting boards or the like respectively positioned in the two housings is provided.

[0047] 4(a) and 4(b) show the structure of the hinge unit 3 according to the present embodiment. In this embodiment, the axial cross-section of the hinge top 3a is substantially cross-shaped. Furthermore, the housing on the operation side 2 includes an ...

[0050] A second embodiment suitable for carrying out the present invention will be described. FIG. 6 shows the configuration of the hinge unit 5 with hooks according to the present invention. The hinge unit 5 with a hook according to the present invention has substantially the same configuration as the hinge unit 3 of the first embodiment, but the hinge hook 5 is provided on the end of the hinge top 5a.

[0051] In the present invention, the end of the hinge top 5a has a hook shape so that the hinge unit 5 having the hook is prevented from coming off.

[0052] Also, the effect of reducing the click sound at the time of hinge capture is similar to that of the first embodiment, so redundant description is omitted.

Abstract

Provided are a hinge structure that is simple and has no deterioration with age and where production of a clicking sound is suppressed, a portable terminal with the hinge structure, and a hinge unit. The hinge structure has a hinge unit (3) where a body and a hinge head (3a) are connected via a rotation shaft so as to be swingable in a predetermined angle range, a display-side housing (1) to which the body is fixed, an operation-side housing (2) into which the hinge head (3a) is inserted with a predetermined gap in between them. When the display-side housing (1) and the operation-side housing (2) are maximally opened, the hinge head (3a) and the operation-side housing (2) are in a surface contact relationship.

Description

technical field [0001] The present invention relates to hinges for rotationally connecting two components together, and more particularly to hinges that reduce the clicking sound when two components are opened or closed. Background technique [0002] In recent years, a type called "folding type" in which an upper case and a lower case are rotatably connected to each other by hinges, respectively, has become the mainstream of mobile terminals typified by mobile phone terminals. [0003] The market demands elegant mobile terminals. That is, not only functionality but also a flawless appearance, demanding a more premium feel. [0004] It is required not only to be visually high-end but also to be high-end aurally, and a terminal that does not produce a click sound when opening and closing is preferred as a high-end product. [0005] One of the hinge units includes what is called a "flipper type", which generates little noise (clicking sound when opened and closed) when caught...
