Lid driver part 2 comprises a rotating element 20, a follower 22 and a latch 24, and rotating element 20 and follower 22 are two to have the cylinder of same outer diameter as size, and latch 24 combines rotating element 20 and follower 22.
Rotating element 20 has a cylindrical shell 20 1 and a cavity 202.Be provided with the key 203 that constitutes rotation stop device in cylindrical shell 201 peripheries, it closely cooperates mutually with detent (figure does not show) in the connecting portion of folding-type electronic device lid (figure do not show), this rotating element 20 is not had with this lid relatively rotate, lid is along its axial motion relatively.Establish two holding parts 204 on the periphery of cylindrical shell 201 1 ends, these two holding parts, 204 bottoms are provided with pin-and-hole 205.Be provided with one second screw thread 206 in the cavity 202, this second screw thread 206 matches with first screw thread 16 of body driver part 1, make rotating element 20 relatively body driver part 1 rotate.
See also Fig. 4, follower 22 1 ends have two extensions 221, which is provided with pin-and-hole 222, the shape and size of this extension 221 are corresponding with the holding part 204 of rotating element 20, and be placed in this holding part 204, pin-and-hole 222 is corresponding with the pin-and-hole 205 of rotating element 20, and latch 24 is interfered in this two pin-and-hole of insertion, and rotating element 20 and follower 22 are combined.The other end inner surface of follower 22 is provided with in it and directly upwards is circular protuberance 223, and this protuberance 223 has a two side faces 2230,2232 and a top 2234.
Stopping element 3 is one to have the cylinder of excellent resilient properties, and its internal diameter size is greater than the diameter of the cylindrical shaft of body driver part 1.The peripheral part of this stopping element 3 disconnects, and forms an oblong openings part 30.Be provided with in it in stopping element 3 one end peripheries and directly upwards be circular projection 31, this projection 31 has a two side faces 310,312 and a top 314.This projection 31 matches with the protuberance 223 of follower 22, make stopping element 3 and follower 22 assemblings after, side 310,2230 contacts.
During assembling, the rotating element 20 of lid driver part 2 is passed an end of body driver part 1, match with second screw thread 206, rotating element 20 is assemblied on the body driver part 1 by first screw thread 16.The follower 22 of lid driver part 2 is passed flange 11 1 ends of body driver part 1, its extension 221 is placed in the holding part 204 of rotating element 20, latch 24 is interfered in insertion two pin-and-holes 205,222, rotating element 20 and follower 22 are combined.After perhaps also can be earlier rotating element 20 and follower 22 being combined by latch 24, refill and be assigned on the body driver part 1.Stopping element 3 is assemblied between flange 11 and the lid driver part 2, the side 310 of projection 31 is contacted with the side 2230 of the protuberance 223 of follower 22. Friction plate 4 and 5 is combined with the recess 14,15 of body driver part 1 respectively, it is immobilizated on the body driver part 1, thereby linkage is fitted together, prevent that each parts of this linkage break away from body driver part 1.Friction plate 4 is between flange 11 and stopping element 3, and to reduce the friction between it, friction plate 5 is between the protuberance 12 and rotating element 20 of body driver part 1, to reduce the friction between it.
See also Fig. 3, Fig. 5 and Fig. 6, when the side 310 of the projection 31 of stopping element 3 contacts with the side 2230 of the protuberance 223 of follower 22, body driver part 1 is relatively stable with lid driver part 2, and the body and the lid of folding-type electronic device are in closure state.
When if the application of force makes the relative body rotating opening of lid, under the cooperation of first screw thread 16 and second screw thread 206, lid driver part 2 rotates with respect to body driver part 1, and it axially moves along body driver part 1 simultaneously, move to its top 314 along the side 310 of the projection 31 of stopping element 3 in the side 2230 of the protuberance 223 of follower 22, inwardly compressing stopping element 3 makes it produce elastic deformation simultaneously, when the top 2234 of protuberance 223 moved to the top 314 of projection 31, this elastic deformation made stopping element 3 have maximum elastic-restoring force.When the top 314 of projection 31 was slightly crossed at the top 2234 of protuberance 223, under the effect of the elastic-restoring force of stopping element 3, lid driver part 2 can be automatically with respect to 1 rotation of body driver part, thereby the relative body of lid is opened automatically.In the automatic opening procedure of the relative body of lid, slide along the side 312 of the projection 31 of stopping element 3 in the side 2232 of the protuberance 223 of follower 22, and it can produce certain frictional force, can prevent because of lid inertia excessively, and folding-type electronic device is subjected to than big bang.
If the application of force makes lid rotate when closed relative to body, under the cooperation of first screw thread 16 and second screw thread 206, lid driver part 2 rotates with respect to body driver part 1, and its while edge axially moves with above-mentioned opposite direction.Move to its top 314 along the side 312 of the projection 31 of stopping element 3 in the side 2232 of the protuberance 223 of follower 22, inwardly compressing stopping element 3 makes it produce elastic deformation simultaneously, when the top 2234 of protuberance 223 moved to the top 314 of projection 31, this elastic deformation made stopping element 3 have maximum elastic-restoring force.When the top 314 of projection 31 was slightly crossed at the top 2234 of protuberance 223, under the effect of the elastic-restoring force of stopping element 3, lid driver part 2 can be automatically with respect to 1 rotation of body driver part, thereby makes the relative body auto-closing of lid.In the relative body auto-closing of lid process, slide along the side 310 of the projection 31 of stopping element 3 in the side 2230 of the protuberance 223 of follower 22, and it can produce certain frictional force, can prevent because of lid inertia excessively, and folding-type electronic device is subjected to than big bang.
The top 314 of projection 31 that is appreciated that the stopping element 3 of the utility model linkage also can see also Fig. 7 for a plane.In lid driver part 2 relative body driver part 1 rotation processes, when the top 2234 of the protuberance 223 of the follower 22 of lid driver part 2 moves to the top 314 of projection 31, because top 314 is a plane, make lid driver part 2 and body driver part 1 relatively stable, promptly all can stop in the optional position, move to the side of projection 31 until the top 2234 of protuberance 223, can satisfy the demand of folding-type electronic device lid and main body multi-angle location thus.
In addition, the top 2234 of the protuberance 223 of the follower 22 of the utility model linkage also can be a plane, perhaps the top 314 of the projection 31 of stopping element 3 is the plane with the top 2234 of the protuberance 223 of follower 22, can satisfy the demand of folding-type electronic device lid and main body multi-angle location.
