When first, second folded sheet 11,12 is in unfolded state, first, second shell 31,32 is opposite Two sides are close to each other up to contacting with each other only, at this point, being hidden in the back-cover 20 of first, second shell 31,32 is interior, Realize preferable appearance, the sense of discomfort of no back-cover protrusion surface.When first, second folded sheet 11,12 folds, institute The first, second shell 31 is stated, 32 opposite two sides are separated from each other until in parastate after spaced apart, at this point, institute It states back-cover 20 to be exposed to outside first, second shell 31,32, the edge difference of 31,32 opposite side of the first, second shell It is bonded with the edge of the lid 21 of the back-cover 20.
The communication apparatus of the application covers the back-cover 20 in unfolded state by first, second shell 31,32, So that the back-cover 20 is in hidden state, realizes the planarization at the communication apparatus back side, appearance is preferable, and is suitable for being flat on desktop, Prevent skew.
Please continue to refer to shown in Fig. 6 to Figure 11, the bindiny mechanism 40 of the application includes at least three fixing seats 41, two and turns Dynamic seat 42 and a pair of of transmission gear 43.
The fixing seat 41 include positioned at two of outside outside fixing seats 411 and be located at two outside fixing seats 411 it Between intermediate fixing seat 412.The rotation seat 42, which is divided to be held on respectively on the outside of one for two Duis with the transmission gear 43, to be fixed It shifts to install between seat 411 and the intermediate fixing seat 412 and in a lateral direction.
Each fixing seat 41 includes the curved base 417 agreed with the back-cover cavity 23 of the back-cover 20, is located at the arc 417 bottom side of shape matrix and the bottom 418 for planar structure, the cooperation fixed part that is opened at the top of 417 arc of curved base 416, positioned at 418 centre of bottom and the avoiding area 414 of part removal formation and consolidating on the cooperation fixed part 416 Determine hole 413.The cooperation fixed part 416 is sunk structure and consolidating the protrusion on 23 top surface of back-cover cavity of the back-cover 20 Determine in part 24 is contained in, and the fixation hole 413 is passed through from the avoiding area 414 by fixing bolt and is anchored on the back-cover 20 Fastener hole 26 in, thus the fixing seat 41 is fixed in the back-cover 20.417 liang of the curved base of the fixing seat 41 Side is equipped with axis hole 415, and an axis hole 415, and the axis of two outside fixing seats 411 can be only arranged in the outside fixing seat 411 Hole 415 is located at different two sides, mutual dislocation.
Emphasis is as shown in fig.9, the rotation seat 42 includes pedestal 421, the arc top surface set on 421 top surface of pedestal 422, positioned at the bottom surface 425 of 421 bottom of pedestal, the arc groove 423 that is opened in the pedestal 421 and from the pedestal The toothing 424 that 421 423 lower section intermediate lateral of arc groove extends to form.The arc groove 423 and the arc top surface 422 The concyclic heart.The part arc cavity of the arc top surface 422 and the back-cover cavity 23 of the back-cover 20, which is agreed with, makes the rotation seat 42 can rotate around the back-cover cavity 23 of the arc.The arc top surface 422 of the rotation seat 42 and the back-cover cavity of the arc 23 rotation meets the optimal folded trajectory of the Folding screen.
The transmission gear 43 includes shaft 431 and the gear 432 being fixed in the shaft 431.The shaft 431 First end is limited in an axis hole 415 of the intermediate fixing seat 412, and the second end of the shaft 431 passes through the rotation It is limited in after the arc groove 423 of seat 42 in the axis hole 415 of an outside fixing seat 411.The shaft 431 of two transmission gears 43 First end is respectively limited by the axis hole 415 of 411 both lateral sides of intermediate fixing seat.Meanwhile the gear 432 with described turn The toothing 424 of dynamic seat 42 is engaged.
When implementing, two rotation seats 42 are individually fixed on first, second folded sheet 11,12, i.e., one The bottom surface 425 of rotation seat 42 is fixed on the first folded sheet 11 and institute is at least partly fixed in the bottom surface 425 of the rotation seat 42 It states on the first protrusion 112 on the first folded sheet 11;Second folded sheet is fixed in the bottom surface 425 of another rotation seat 42 The second protrusion 121 on second folded sheet 12 is at least partly fixed on the 12 and bottom surface 425 of the rotation seat 42.And When first, second folded sheet 11,12 is in linking unfolded state, positioned at the first protrusion 112 of the first folded sheet 11 On rotation seat 42 be located on the second notch 122 of second folded sheet 12;Positioned at the second protrusion of the second folded sheet 12 Rotation seat 42 on 121 is located on the first notch 111 on first folded sheet 11.
In actuation, first, second folded sheet 11,12 drives disposed thereon respectively for the bindiny mechanism 40 of the application Two rotation seats 42 are rotated around the arcwall face of the back-cover cavity 23 of the back-cover 20, at this point, the toothing on the rotation seat 42 424 drive the gear 432 of the transmission gear 43 to rotate, and rotate the shaft 431 around the arc groove 423 of the rotation seat 42 Until the toothing 424 of the rotation seat 42, which turns to end position from initial position, stops (emphasis is as shown in figure 11).Described turn The folded trajectory of the arching trajectory and the Folding screen of the arc groove 423 of dynamic seat 42 agrees with, and guarantees the folding path symbol of Folding screen Optimal path is closed, the Folding screen is avoided to damage.
The bindiny mechanism 40 of the application is by the way that dislocation clamps a rotation seat 42 and one respectively between three fixing seats 41 Transmission gear 43, and the gear 432 of the occlusion transmission gear 43 of toothing 424 on the rotation seat 42 rotate, and pass through The shaft of transmission gear 43 is limited in the limitation realized in the arc groove 423 of the rotation seat 42 to 42 position of rotation seat, The arc groove 423 of the rotation seat 42 rotates the expansion and closure for realizing the first, second folded sheet 11,12 around the shaft 431.
