Description
Technical field
The utility model relates to the synchronous guiding mechanism of a kind of twin axle pivot button, particularly for the twin axle pivot button being installed on the electronic ware that can raise and cover, and relate to a kind of synchronous guiding mechanism being disposed between two rotating shafts of twin axle pivot button, especially about the poor wobble plate of torsion in order between balance two rotating shafts.
Background technique
Traditional notebook computer, mobile phone, PDA, numerical digit camera or e-book etc. possess the electronic ware that can raise and cover ability, its display modular (for example, screen) and body module is (for example, main frame, keyboard) between, being typically provided with the single external force of accepting drives and reciprocating rotation rotating shaft freely, and come display modular and body module described in companding via the action of raising and covering, be beneficial to use operation and collection, be conventionally not more than 180 degree but this class is provided with the angle of raising of the electronic ware of single rotating shaft.
For the display modular and the body module that make electronic ware possess more operator scheme and application area in use, there is on the market a kind of technology that two rotating shafts are set between display modular and body module; Lift as Patent Cases such as TaiWan, Chinas No. 100224345 " Double-shaft pivot device of tool limit function " and No. 101210179 " pulley locking-type twin shaft pivot ", 0 to 360 degree that makes can relatively overturn between display modular and body module, and produce different operator schemes.
The prior art of above-mentioned pair of rotating shaft be mainly that two rotating shafts that are parallel to each other are set between display modular and body module, and the common hub setting of two rotating shafts is on a pin joint seat; Each rotating shaft two ends be set as respectively one in order to hub setting the pin-joint part on pin joint seat, and one in order to the fixing part in conjunction with described display modular, body module, and it is arbitrarily angled that described display modular and body module are rocked to based on pin joint seat upset separately, make electronic ware produce the operation form of different mode.
The pin-joint part of aforementioned each rotating shaft be provided with one can with runner and one group of elastic device of rotation, this elastic device is made up of the dish-like reed of majority, and pin joint seat is between runner and elastic device.So, the elastic force of this elastic device can drive pin joint seat to move toward runner direction, touches runner, makes two rotating shafts produce separately torsion, be beneficial to locate described display modular and body module in arbitrarily angled and pin joint seat is pasted.
In addition, for make described display modular and body module to open and close process more smooth and easy, also exist on the market at present a kind of can be by the design of described display modular and the mutual interlock of body module, be mainly active configuration a actuator between two rotating shafts, this clutch is normally made up of most pitch wheel; And the subsides of each runner and pin joint seat are touched face and are provided with separately sag and swell, this sag and swell normally arranges protuberance and forms on runner, pin joint seat surface.
Thus, in the time lifting display modular, the rotating shaft of this display modular is rotated thereupon, and changes the relative position between the rotating shaft of display modular and the sag and swell of the tactile face of subsides, and order about the elastic device of pin joint seat compression display modular, to overcome the torsion of rotating shaft of display modular.Meanwhile, the rotating shaft of this display modular is synchronously rotated by the rotating shaft of this body module of clutch interlock, and makes described display modular and the mutual folding running of body module.
But, when the rotating shaft of display modular is synchronously rotated moment by the rotating shaft of clutch interlock body module, because user is conventionally only to the display modular application of force, therefore be from clutch in order to the active force of the elastic device of compressor body module, cause the uneven situation of active force of the elastic device of display modular and body module described in outer force compresses, the runner bear of each rotating shaft like this is not identical from the elastic force of elastic device yet, cause that between each rotating shaft, to produce torsion poor, and affect the parallelism between each rotating shaft, cause opening of display modular and body module, close and have some setbacks, the problem that even causes each rotating shaft to produce wearing and tearing or block, affect the validity of synchronous rotating mechanism.
In addition, the technology of the two rotating shafts of aforementioned conventional, normally elastic device is located to the pin-joint part end of rotating shaft, and runner is located at the position of the contiguous fixing part of pin-joint part front end of rotating shaft, this runner is except rotating with rotating shaft, still need the elastic force that bears elastic device order about and slide along rotating shaft, therefore the gap between runner and rotating shaft is difficult to reduce, and easily causes runner to produce the problem of idle stroke.
In view of this, inventor spy of the present utility model specializes in the many years of experience of production, manufacture and the design of electronic ware pivot button with it, and then grinds and create the utility model, to overcome above-mentioned disappearance of the prior art.Model utility content
