In first notch 114 of plate 11.
60 operation principles of the application Balance route mechanism are as follows:
In first, second folded sheet 11,12 rotation, drives two rotation seats 42 to rotate respectively and make rotation seat 42
Toothing 424 drive the third gear 674 of described 673 one end of the second axle body to rotate, and then drive the second axle body 673 another
The second gear 675 of one end rotates, and the second gear 675 drives the first gear 672 on the first axle body 671 when rotating
Rotation.And be held on the damping piece 69 on the first axle body 673 and apply resistance to the first axle body 673, make described first,
Second folded sheet 11,12 can rest on any folding position during rotation.The concave 68 is in the spring 66
It is caught in the card slot 644 under elastic force and exits the two states realization folding feel of the card slot 644, i.e., the described concave 68
Fixture block 682 can generate apparent feel prompt and fold completion status when being caught in the card slot 644.
For emphasis refering to fig. 1 shown in 7, the radius of the second gear 675 is less than the radius of the first gear 672.It is described
The bottom of clamping plate 65, which is again provided with, keeps away bit space 651, and first, second gear 672,675 is along the side for keeping away bit space 651
Edge setting.The setting of four occlusion gears, can make the radius for reducing the gear and reach identical transmission distance, that is, reduce
The thickness of the Balance route mechanism 60.
The Balance route mechanism 60 of the application is by being arranged a pair of of the first axle body 671 and a pair of of the second axle body 673 and making it
On a pair of of first gear 672 be engaged rotation with a pair of of second gear 675, must when the folding of first or second folded sheet 11,12
So first, second folded sheet 11,12 is set to fold same angle by the transmission of first, second gear 672,675.
Meanwhile by the setting of the damping piece 69 and the concave 68, enhances user and folding angles are positioned and folded with feel
Better experience.
The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art
For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal
Replacement, improvement etc., should be included within the scope of the claims of this application.
