Twin-axle type pivot structure

Abstract

The invention relates to a double-shaft rotating shaft structure, which consists of a pin joint seat, a first rotating shaft and a second rotating shaft, wherein a first embedding part and a second embedding part of the first and the second rotating shafts are overlapped with each other vertically and are pivoted to the pin joint seat; and through the special design of a locking and unlocking mechanism for the first and the second embedding parts, the first and the second rotating shafts cannot rotate simultaneously, but only a single rotating shaft can rotate, particularly the first and the second rotating shafts are provided with a torque force adjusting device respectively for adjusting the torque force of the first and the second rotating shafts respectively. Particularly, the first rotating shaft and / or the second rotating shaft can be additionally provided with a torsional spring optionally so that the rotating shafts have a hand feeling of light opening and heavy closing and can serve as automatic breaking design.

Description

technical field [0001] The invention relates to a rotating shaft structure, in particular to a double-shaft rotating shaft structure. Background technique [0002] 3C consumer electronic products with flip function, such as portable computers, electronic dictionaries, portable audio-visual playback devices, portable photography equipment, or flip-type mobile phones, etc., basically, put a first body It is located in the lower half, and is connected with the second body of the upper half through the rotating shaft structure, so that the second body can be opened and closed relative to the first body. Therefore, the structure of the rotating shaft is also a major factor in determining the quality of the above-mentioned products. [0003] In recent years, due to the ever-changing functions of 3C electronic products, the traditional way of pivoting the first and second bodies with a first shaft to make the second body open and close relative to the first body is no longer suffi...

Problems solved by technology

[0004] From the technical content of this prior art, it can certainly achieve the purpose of biaxial rotation, but, from the perspective of its overall structure, it does not have the function of torque adjustment, nor does it have the function of "opening light and closing heavy", even As an enhancement of functions such as "automatic pop-up", there are indeed some problems that need to be overcome and improved in structure.
