In another embodiment, can not need switch 11, for example, motor 12 can detect second component 1b and control with respect to the angle of inclination of first component 1a by the process chip (not shown) of folding-type electronic device 1.

Gear set 13 comprises one first worm screw 131(worm gear), one first spur gear 132(spur gear), one second spur gear 133 and one second worm screw 134.The first worm screw 131 is connected with motor 12, and with an axle center AX1 rotation, aforesaid axle center AX1 extends along a first direction D1.The first spur gear 132 and the first worm screw 131 engagements, and with an axle center AX2 rotation.The second spur gear 133 and the first spur gear 132 engagements, and with an axle center AX3 rotation.The second worm screw 134 and the second spur gear 133 coaxially arrange 20 engagements of ，Bing Yu travel mechanism.Aforementioned axle center AX2, AX3 extend along a second direction D2, and first direction D1 is perpendicular to second direction D2.

By the structure of aforesaid gears group 13, can make driving mechanism 10 be arranged in the folding-type electronic device 1 of slimming, in addition, aforesaid gear set 13, is only an embodiment, not in order to limit the scope of the invention.

Travel mechanism 20 comprises a tooth row 21 and a retaining element 22, and tooth row 21 is engaged in the second worm screw 134 of gear set 13, and tooth row 21 has a pickup groove 211, and can rise or decline along second direction D2.Retaining element 22 is a loop configuration, is articulated in pivot 30.Retaining element 22 has a holding section 221, is fixed on tooth row 21.

Pivot 30 comprises that an articulated section 31 and is arranged at the fixed part 32 of articulated section 31, and articulated section 31 and fixed part 32 extend along a third direction D3, and wherein first direction D1, second direction D2 and third direction D3 are mutually vertical.Second component 1b is fixed on fixed part 32, and retaining element 22 is socketed and is articulated in articulated section 31, and second component 1b can rotate with respect to first component 1a thus.

In the present embodiment, when motor 12 forward rotation, drive tooth row 21 to rise along second direction D2, so that travel mechanism 20 and pivot 30 are positioned at a primary importance, when motor 12 rotates backward, drive tooth row 21 to decline along second direction D2, so that travel mechanism 20 and pivot 30 are positioned at a second place.Control motor 12 forward rotation, rotate backward or the mechanism stopping operating, be not emphasis of the present invention, and known by the people who is familiar with this art, in this, do not add explanation.

As shown in Figure 4, first component 1a has a positive S1, and a back side S2 in contrast to positive S 1.When second component 1b is covered on positive S1Shi， travel mechanism 20 and pivot 30 is positioned at primary importance.Now pivot 30 surpasses positive S1, therefore can allow second component 1b have enough spaces to be covered on positive S1.

As shown in Figure 5, when second component 1b is positioned at an angle of inclination A1Shi， travel mechanism 20 with respect to first component 1a and pivot 30 is positioned at a primary importance, now, user can use folding-type electronic device 1 as a notebook computer.Afterwards, driving mechanism 10 can drive travel mechanism 20 and pivot 30 to move to the second place in Fig. 6 by primary importance, or moves to primary importance by the second place.In this embodiment, aforesaid angle of inclination A1 can be between 90 degree to 270 degree.

In detail, when second component 1b moves to the angle of inclination A1 of Fig. 5 by the position that is covered on the positive S1 of first component 1a, driving mechanism 10 starts, so that the second worm screw 134 of driving mechanism 10 is rotated.The second worm screw 134 drives the tooth row 21 of travel mechanism 20 to decline along second direction D2, and drives in the lump retaining element 22 and pivot 30 to move to the second place by primary importance.

As shown in Figure 6, Figure 7, when travel mechanism 20 and pivot 30 are positioned at a second place, pivot 30 surpasses back side S2, so can allow second component 1b have enough spaces to be rotated further, to allow second component 1b can be covered on the back side S2 of first component 1a, now folding-type electronic device 1 can be used as a panel computer use, also or make second component 1b be positioned at the dorsal part of first component 1a as shown in Figure 7, now user can be positioned over the positive S1 of first component 1a as in the planes such as desktop, to facilitate user to carry out touch-control for second component 1b.Aforesaid dorsal part is corresponding to back side S2, and the positive side of first component 1a is corresponding to positive S1.

In like manner, when second component 1b by be covered on first component 1a back side S2 position or at the dorsal part of first component 1a as shown in Figure 7, move to angle of inclination A1(or another angle of inclination between 90 degree to 270 degree of Fig. 5) time, driving mechanism 10 starts, so that the second worm screw 134 of driving mechanism 10 is rotated.The second worm screw 134 drives the tooth row 21 of travel mechanism 20 to rise along second direction D2, and drives in the lump retaining element 22 and pivot 30 to move to a primary importance (as shown in Figure 5) by the second place (as shown in Figure 6).

Due between first component 1a and second component 1b only with pivot 30 pivot joints, so user can comparatively successfully rotate second component 1b with respect to first component 1a.

In another embodiment, driving mechanism 10 and travel mechanism 20 can further simplify, for example can reduce the included element of gear set 13, or driving mechanism 10 can not comprise switch 11 and motor 12, travel mechanism 20 also can not comprise tooth row 21, driving mechanism 10 can be comprised of elements such as connecting rods, user utilizes manual mode to pull driving mechanism 10 with the retaining element 22 of mobile travel mechanism 20, thereby makes travel mechanism 20 and pivot 30 rise to primary importance or drop to the second place along second direction D2.

Though the present invention discloses as above with various embodiment, yet it is only for example reference but not in order to limit scope of the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention, when carrying out many changes and change.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 is worked as claims restriction depending on enclosing is as the criterion.
