Problems solved by technology

[0003] However, this mechanism is difficult to operate because it requires pushing a small push button toward the pivot
In addition, there is also a problem that when the portable terminal is held in a handbag and transported, when the push button is pressed due to impact or the like, the opening operation will be performed unintentionally.
Moreover, there is also the problem that if the unintentional opening action is to be prevented, there is a method of strengthening the biasing force of the spring for pressing and restoring the button, but if the pressing force is strengthened in this way, it is necessary to use a strong force when pressing the button, which is very difficult. inconvenient

Embodiment 1

[0070] FIG. 1 is a perspective view showing the appearance of a mobile phone 1 .

[0071]The mobile phone 1 is composed of a main body 7 having a key arrangement surface 6 on which input keys (not shown) and the like are arranged, and a cover 2 having a display surface 3 on which a liquid crystal screen (not shown) and the like are arranged. The cover 2 and the main body 7 can be folded and opened from the closed state where the key arrangement surface 6 and the display surface 3 overlap each other to the open state where the key arrangement surface 6 and the display surface 3 are rotated and opened by 170 degrees through the connection parts 4 (4a, 4b) and the connection part 5 respectively provided. closed connection.

[0072] A hinge device 10 described below is housed inside the connecting portion 5 of the main body 7 and inside the connecting portion 4 b of the cover 2 .

[0073] 2 and 3 are exploded perspective views of the hinge device 10 , and FIGS. 4 and 5 are perspe...

Embodiment 2

[0096]Next, the hinge device 110 of the second embodiment will be described. The hinge device 110 has the same mechanism as that of the above-mentioned first embodiment, and has an added function of automatically pivoting when the cover 102 and the main body 107 are superimposed on each other when they deviate in the left and right directions.

[0097] 10 and 11 show exploded perspective views of the hinge device 110 , and FIGS. 12 and 13 show perspective views of the hinge device 110 in a state where the housing is removed.

[0098] The hinge device 110 is composed of E rings 113a, 113b, 113c, 181, washers 148a, 148b, 148c, left mounting arm 210, width adjustment housing 215, sliding ring 220, support plate 230, stopper 120, shaft 140, pressing spring 145 , rotation spring 125, main body side cam 150, main body side housing 130, locking release member 240, cover side cam 170, opening and closing stabilizing member 250, right mounting arm 260, shaft hole seat 269, lateral rota...

Embodiment 3

[0129] Next, the hinge device 310 of the third embodiment will be described. The hinge device 310 has the same mechanism as that of the above-mentioned second embodiment, and has a function of automatically pivoting when the cover 102 (see FIG. 17 of the second embodiment) and the main body 107 are overlapped and shifted in the left and right directions.

[0130] 19 and 20 are exploded perspective views of the hinge device 310 , and FIGS. 21 and 22 are perspective views of the hinge device 310 with its case removed.

[0131] The hinge device 310 is mainly composed of a shaft 340, a fixed part 326, a stopper 320, a rotating spring 325, a main body side casing 330, a pressing spring 345, a washer 348, a main body side cam 350, a cover side casing 360, a cover side cam 370, and a sliding cam 410. , a support plate 430, a rotating base 470 and a fixed base 480.

[0132] The shaft 340 has a generally cylindrical shape as a whole, and a terminal protrusion 344 that engages with the...

Abstract

A hinge mechanism is arranged with first and second cams fixed to first and second housings respectively; a press biasing unit for press biasing the first cam and the second cam in a direction of approaching each other with the first convex part of the first cam and the second convex part of the second housing opposing each other; and a pivot biasing unit for biasing the first cam and the second cam to relatively pivot in an opening direction with the pivot axis as the center. Pivoting in the opening direction by the pivot biasing unit is stopped when the first convex part and the second convex part contact each other. The press biasing unit has a press biasing force of a strength that the other contacting part does not ride over an inclined surface by the pivot bias of the pivot biasing unit.

Description

technical field [0001] The present invention relates to a hinge mechanism and a portable terminal, which are used in portable terminals such as mobile phones and PDAs, for example, in which a first housing and a second housing are connected in a foldable, openable and closable manner. Background technique [0002] At present, in portable terminals such as mobile phones, a hinge mechanism that performs folding and opening and closing, which is called a clamshell type, is often used. As a hinge mechanism for performing such folding and opening and closing, there has been proposed a mechanism that can switch from the closed state to the open state by one-touch operation by pressing a button provided at the end of the pivot in order to realize a semi-automatic opening operation. (Refer to Patent Documents 1 and 2). [0003] However, since this mechanism needs to press a small push button in the direction of the pivot, it is difficult to operate. In addition, there is also a pr...
