Abstract
The utility model discloses a double-shaft hinge capable of being opened and closed smoothly. According to the double-shaft hinge, a ball bearing is utilized to locate and the rotations of a first revolving shaft and a second revolving shaft are selectively limited, so that a 360-degree opening and closing effect is achieved; and an angular deflection problem is not generated because of the ball-shaped appearance of the ball bearing, and the problem that the opening and closing of the general double-shaft hinge are not smooth is solved. Meanwhile, the surface of the ball bearing can be in contact with both a first revolving part and a second revolving part because of the appearance of the ball bearing, so that the double-shaft hinge is uniformly abraded, and the service life is prolonged.
Description
Technical field
The utility model relates to the hinge technical field, especially relates to a kind of biaxial hinge of smooth and easy folding.
Background technique
General cover-lifting type electronic device such as notebook computer, mobile phone etc. are provided with hinge between the display screen of this electronic equipment and keyboard.This hinge is taked the hinge with single axle the earliest, though can reach the purpose that display screen can pivotable with respect to keyboard be raised, but be subject to the design of display screen and keyboard appearance housing, can influence each other when display screen shell and keyboard case are opened into several angle and can't continue to open, must yield to structure in appearance design for avoiding affecting, and appearance design is restricted.
For this reason, someone has designed a kind of double-axis hinge of Rotatable displacement, its display/panel bracket is combined with the first rotating shaft, base seat support is combined with the second rotating shaft, and the first rotating shaft is rotated around the second rotating shaft actively, and changes the position of the first rotating shaft, makes the first rotating shaft can be up or displacement backward, and then the driving display screen support up or displacement backward, and in the time of can avoiding opening, display screen shell and base shell influence each other.Though when this kind design can be avoided opening, the display screen shell influences each other with base shell, surpass 180 degree but still can't open, can't adapt at present and popularly on the market to have an electronic equipment that touch-control type or handwriting input operate.Because people wish that the display screen shell of this kind electronic equipment and keyboard case can overturn greater than 180 degree, facilitating the demand of touch-control input, or oppositely superimposedly carry out touch control operation with convenient the gripping.
In order to meet the trend of present development touch control electronic device, a kind of biaxial hinge of stable folding is designed in the utility model people research and development.This hinge includes 1 link and is arranged at 1 the first rotating component and 1 the second rotating component on this link, this first rotating component includes 1 the first rotating shaft, and this first rotating shaft has 1 the first butting section and 1 the first positioning groove of being located on this first butting section.This second rotating component includes 1 the second rotating shaft, and this second rotating shaft has 1 the second butting section and 1 the second positioning groove of being located on this second butting section.This link includes 1 orbit portion of being located between this first rotating shaft and this second rotating shaft, and 1 slip positioning part of being located at this orbit portion.This slip positioning part and butting section and positioning groove with different against mode mutually against, make this first rotating shaft and this second rotating shaft have respectively can the Rotate 180 degree rotating distance, and then can make display screen and base folding 360 degree of electronic equipment.
Yet, the slip positioning part of the biaxial hinge of aforementioned stable folding is cylindrical body, it is along this orbit portion displacement the time, may produce skew, can't with this first rotating shaft and this second rotating shaft keeping parallelism, thereby this first rotating shaft and this second rotating shaft are had some setbacks when rotating, and need to apply larger strength could rotate.Time is slightly long, and this slip positioning part is easily damaged, and needs to change this slip positioning part, causes the waste on cost.Therefore be necessary to be improved.
