Description
Technical field
The utility model relates to electronic equipment machinery technical fields, more particularly, to two-period form torque pivot device.
Background technique
Existing electronic product, such as laptop, usually in system end design have can relative system end folding
Screen display end in this way, can not only raise screen display end in working condition, but also can be closed screen display end in transportation.It is aforementioned to complete
Operation, multiselect use dual-axis pivot device as connection structure, and such pivot device generally includes first rotating shaft and the second shaft, this first
Shaft, which is connect with the second shaft through interlinked mechanism, has synchronous rotary effect, and different in order to be able to rotate screen display end
Angle simultaneously positions, and is also devised with torsion mechanism in such pivot device to provide the torsion at positioning screen display end.But existing twin shaft pivot
Torsion caused by torsion mechanism is mostly steady state in axis device, namely can only generate the torsion of definite value, if need to increase torsion
Strength then needs the structure for changing pivot device, this will certainly be caused in limited design space, and structure is complicated and cost is excessively high
Problem.
Utility model content
The purpose of the utility model is to overcome the above problems of the prior art, provide two-period form torque pivot device, can mention
Torsion is positioned for modified two-period form, and meets the torsion demand of screen display end different location with this.
The purpose of this utility model is achieved through the following technical solutions:
Two-period form torque pivot device, including fixed bolster are provided through first rotating shaft on fixed bolster and with first
Shaft the second shaft disposed in parallel, first rotating shaft and the second shaft can be rotated relative to fixed bolster；
It is interlocked in first rotating shaft and is provided with first gear, the outer peripheral surface of first gear has the first cancave cambered surface and the first grinding tooth
Face, the first grinding tooth face have several first grinding tooths；
It is interlocked in second shaft and is provided with second gear, the outer peripheral surface of second gear has and the first cancave cambered surface gap setting
And the second grinding tooth face that flank engagement can be nibbled with first, there are on the second grinding tooth face several second grinding tooths；
Further including can be with the positioning torsion component of first rotating shaft and the second shaft interference engagement.
In the utility model, positioning torsion component is used to provide positioning torsion for first rotating shaft and the second shaft with fixed screen
The position at aobvious end.When the utility model is applied to laptop, system end can be connected with fixed bolster, and screen display end can be with the
One shaft is connected.Since first gear has the first cancave cambered surface and the first grinding tooth face, the process of raising at screen display end will form
Two different torsion interference engagements, one be the first cancave cambered surface and the second grinding tooth face clearance fit when, the rotation at screen display end only can
Cause the rotation of first rotating shaft, at this moment, positioning torsion component is turned round because the rotation compression of first rotating shaft can generate lesser first segment
Power；Two for the first grinding tooth face and the second grinding tooth face engaged transmission when, rotation meeting at screen display end is so that first rotating shaft and the second shaft
It generates and interlocks rotation, at this moment, positioning torsion component can generate biggish the because the rotation of first rotating shaft and the second shaft is compressed
Two sections of torsion.As it can be seen that the utility model can provide modified two-period form positioning torsion, and screen display end difference position is met with this
The torsion demand set.
