Embodiment

Fig. 1 is the stereogram of folding-type electronic device 1 of the present invention.Folding-type electronic device 1 can be a notebook computer.Folding-type electronic device 1 comprises a first component 10, a second component 20, a rotary shaft mechanism 30(hinge mechanism) and a stop mechanism 40.First component 10 can be a screen, and aforesaid screen can be a Touch Screen.Second component 20 can be a main frame, and it can comprise the various electronic components such as keyboard, touch-control version, Touch Screen, central processing unit (CPU), storage, host board.Rotary shaft mechanism 30 is arranged at first component 10, and second component 20 is articulated in rotary shaft mechanism 30, so first component 10 can rotate with respect to second component 20 via rotary shaft mechanism 30.

Fig. 2 is the stereogram of rotary shaft mechanism 30 of the present invention and stop mechanism 40.Fig. 3 is the exploded view of rotary shaft mechanism 30 of the present invention and stop mechanism 40.Rotary shaft mechanism 30 comprises a pivot 31 and a limit element 32.Pivot 31 is arranged at first component 10, and comprises a fixing part 311 and a pin-joint part 312.Fixing part 311 is connected in pin-joint part 312, and all extend along a bearing of trend D1 fixing part 311 and pin-joint part 312.

The sidewall of fixing part 311 has a tangent plane 3111, and first component 10 is fixed on fixing part 311.Pin-joint part 312 is a cylindrical-shaped structure, and second component 20 is articulated in pin-joint part 312, so second component 20 can rotate with respect to first component 10 via pivot 31.The pin-joint part 312 of pivot 31 can provide a torsion between first component 10 and second component 20, and when preventing that first component 10 from tilting with respect to second component 20, first component 10 drops fast.

Limit element 32 is arranged at pivot 31.Limit element 32 can be a gear, and has a plurality of tooth portion 321 and a fixed hole 322.321 annular arrangements of tooth portion are in the outer side wall of limit element 32, the sidewall of the form fit fixing part 311 of fixed hole 322, and fixed hole 322 has a plane 3221 that is fixed the tangent plane 3111 of portion 311.Therefore,, when fixing part 311 runs through limit element 32 along bearing of trend D1, limit element 32 can be fixed on fixing part 311.

Stop mechanism 40 comprises a stop element 41, a driving element 42 and a switch element 43.Stop element 41 is arranged at second component 20 movably.Stop element 41 can be a tooth row, and extends along a movement direction D2, and aforesaid movement direction D2 can be mutually vertical with bearing of trend D1.In addition, one end of stop element 41 has a blocked part 411.

Driving element 42 is in order to move stop element 41 along movement direction D2.Driving element 42 comprises a motor 421 and a gear 422.Gear 422 is arranged at motor 421, and meshes with stop element 41.Switch element 43 can be arranged at the side that is adjacent to driving element 42 of second component 20, design that can simplified wiring.In another embodiment, switch element 43 can be arranged at the side of the leading edge of first component 10, to facilitate user to operate.

Switch element 43 is coupled to motor 421.Switch element 43 produces one according to a touch-control event and drives signal, and makes motor 421 and gear 422 rotations after driving element 42 reception driving signals.Due to gear 422 and stop element 41 engagements, therefore, driving element 42 can move stop element 41 along movement direction D2, so that stop element 41 and limit element 32 spaces, now, limit element 32 is rotatable.

And when switch element 43 stops producing driving signal, driving element 42 moves stop element 41, so that stop element 41 is connected to limit element 32.Now, the blocked part 411 of stop element 41 is sticked between two adjacent tooth portions 321 of limit element 32, to limit limit element 32 rotations.

In another embodiment, stop mechanism 40 can not comprise switch element 43, driving element 42 can not comprise the elements such as motor 421 and/or gear 422, and driving element 42 can comprise the elements such as connecting rod, and user can directly carry out mobile stop element 41 via manually-operable driving element 42.

Fig. 4 is the sectional view of folding-type electronic device 1 of the present invention.Wherein first component 10 is covered on second component 20, and stop element 41 is positioned at a primary importance.Now, because switch element 43 is not triggered, so driving element 42 blocked part 411 of controlling stop elements 41 is sticked between two adjacent tooth portions 321 of limit element 32, to limit limit element 32 rotations.Because limit element 32 cannot rotate, so first component 10 cannot rotate relative to second component 20 easily.Can prevent that first component 10 is opened with respect to second component 20 when carrying foldable electronic equipment 1.

As shown in Figure 5, when user's wish is opened first component 10 with respect to second component 20, user can make switch element 43 produce one by push switch unit 43 and drive signal, driving element 42 receives and drives after signal, mobile stop element 41 is so that the blocked part 411 of stop element 41 departs from two adjacent tooth portions 321 of limit elements 32, and makes stop element 41 be positioned at a second place.Now, due to stop element 41 and limit element 32 spaces, so limit element 32 be rotatable with respect to second component 20, and first component 10 can be with respect to second component 20 rotations (as shown in Figure 6).

Therefore, in the present embodiment, when user rotates first component 10, only the pin-joint part 312 by pivot 31 provides suitable torsion, so user can rotate first component 10 easily.

As shown in Figure 7, when user turns to an angle of inclination by first component 10 with respect to second component 20, user can release-push unit 43, and now, switch element 43 stops producing and drives signal.Driving element 42 moves stop element 41 and moves to primary importance by the second place, so that stop element 41 is connected to limit element 32.

Because the blocked part 411 of stop element 41 is sticked between two adjacent tooth portions 321 of limit element 32, stop element 41 restriction limit elements 32 rotations, can maintain the relative position between first component 10 and second component 20 whereby.When user carries out the operations such as touch-control to first component 10, although first component 10 is applied in larger pressure, first component 10 also can maintain identical angle of inclination.

In sum, folding-type electronic device of the present invention can maintain the angle of inclination of first component by stop element butt limit element, carry out the operations such as touch-control for user for first component.When stop element departs from limit element, user can rotate first component like a cork with respect to second component.

Though the present invention discloses as above with various embodiments, yet it is only for example reference but not in order to limit scope of the present invention, and those skilled in the art without departing from the spirit and scope of the present invention, can make change and the modification of part.Therefore above-described embodiment is not in order to limit scope of the present invention, and the scope that protection scope of the present invention should define depending on appending claims is as the criterion.
