Retaining piece 3 comprises substrate 31, offer and can insert logical circular holes (indicating) in the central authorities of substrate 31 at first cylinder 21 of fixed block 2, from substrate 31 to the retaining sheet 32 that extends away from substrate 31.Wherein retaining sheet 32 is provided with holding hole 33.
Revolving part 4 also is a hollow cylinder, and it comprises can insert logical through hole 41 with hinge axis 1, this through hole 41 is convexly equipped with and axially extended fixing part 43 to the grafting keyway 42 that can cooperate with the lock key 12 of hinge axis 1 of the outer circumferential face extension of revolving part 4 and the outer surface of spinning part 4 certainly.Fixing part 43 is used for surface engagement within the auxiliary section 72 with the butt bolt 7 of hinge structure 100.One end of revolving part 4 be in order to pressured pressured 44 of main spring 5, the other end of spinning part 4 is to being extended with the 3rd mountain peak 45 and the 4th mountain peak 46 away from pressured 44.During assembling, the 3rd mountain peak 45 and the 4th mountain peak 46 connect with first mountain peak 25 and the second mountain peak bullet of fixed block 2 respectively, the 3rd mountain peak 45 comprises the 5th greatly sloped side 451, the six greatly sloped sides 452 and connects the 5th greatly sloped side 451 and the 3rd gently sloping surface 453 of the 6th greatly sloped side 452; The 4th mountain peak 46 comprises the 7th greatly sloped side 461, the eight greatly sloped sides 462 and connects the 7th greatly sloped side 461 and the 4th gently sloping surface 463 of the 8th greatly sloped side 462.The 5th greatly sloped side 451 of revolving part 4 has the identical gradient with the 7th greatly sloped side 461, and the 6th greatly sloped side 452 also has the identical gradient with the 8th greatly sloped side 462, and setting also is the stationarity when guaranteeing hinge structure 100 rotations like this.In addition, on the revolving part 4 from pressured 44 to being extended with the sleeved part 441 that is used for sheathed main spring 5 away from pressured 44.
Butt bolt 7 is a hollow cylinder, can connect the lid of folding-type electronic device, and it comprises rounded bottom surface 71 and 71 cylindrical sidewall of extending (not indicating) from the bottom surface.Wherein the central authorities of bottom surface 71 offer and can insert logical inserting hole (not indicating) for hinge axis, sidewall outwards convexes with the auxiliary section 72 that two fixing parts 43 that are used for revolving part 4 cooperate, and also is provided with the some projections 73 in the holding hole 33 that is held in retaining piece 3 on the sidewall.
Returnning spring 6 is the column spring also, is set on the hinge axis and occupies to be sent in the main spring 5, and an end is pressed on the shaft shoulder 13 of hinge axis 1, and the other end is replaced the bottom surface 71 at butt bolt 7.
During assembling, at first with on the lock key 12 of the grafting keyway 42 insert hinge axles 1 of revolving part 4 and its sleeved part 441 is connected on the shaft shoulder 13 of hinge axis 1, secondly fixed block 2 is inserted by its through hole 22 and led on the hinge axis 1, this moment, the flat key groove 231 of fixed block 2 was embedded on the flat key 11 of hinge axis 1, first greatly sloped side 251 on first mountain peak 25 of fixed block 2 connects with the 6th greatly sloped side 452 bullets on the 3rd mountain peak 45 of revolving part 4, simultaneously, the 8th greatly sloped side 462 bullets on the 4th mountain peak 46 of the 3rd greatly sloped side 261 on second mountain peak 26 of fixed block 2 and revolving part 4 connect.Then main spring 5 and Returnning spring 6 are passed hinge axis 1 and be connected to respectively on the shaft shoulder 13 of pressured 44 of revolving part 4 and hinge axis 1.At last butt bolt 7 is inserted on the hinge axis 1 with direction from right to left by inserting hole, and the holding hole 33 of retaining sheet 3 is held on the projection 73 of butt bolt 7.
The above-mentioned hinge structure that assembles 100 is inserted the joint (not shown) of the body and the lid of folding-type electronic device, the positioning part 211 of the fixed block 2 on the hinge structure 100 is cooperated with body, the auxiliary section 72 of butt bolt 7 cooperates with body.Here hinge axis 1 is not fixed with respect to body or lid, but because the flat key 11 on the hinge axis 1 and the existence of lock key 12, hinge axis 1 with can not be with respect to the rotation of body or lid but slidably mode be configured in the folding-type electronic device.
During unlatching, at first push hinge axis 1 with hand, make lock key 12 on the hinge axis 1 just break away from the grafting keyway 42 of revolving part 4, because the length that is shorter in length than flat key 11 of lock key 12, the flat key 11 on the hinge axis 1 does not break away from the flat key groove 231 of fixed block 2.Then, unfold the lid of folded electronic equipment with handspring, lid driven rotary part 4 rotates like this, the 6th greatly sloped side 452 of revolving part 4 and the 8th greatly sloped side 462 are creeped along first greatly sloped side 251 and the 3rd greatly sloped side 261 of fixed block 4 respectively under the situation that overcomes main spring 5 and Returnning spring 6 compressing power, when the 6th greatly sloped side 452 and the 8th greatly sloped side 462 break away from first greatly sloped side 251 and the 3rd greatly sloped side 261 respectively and first gently sloping surface 253 and second gently sloping surface 263 when inserting the 3rd gently sloping surfaces 453 and the 4th gently sloping surface 463, handle unclamps, and lid can overturn automatically with respect to body like this.When second greatly sloped side 252 that slips over fixed block 2 up to the 5th greatly sloped side 451 and the 7th greatly sloped side 461 of revolving part 4 and the 4th greatly sloped side 262, the relative body of the lid of this electronic equipment is opened fully.
When closing, push lid with hand, lid is rotated along described second direction relative to body, when the 3rd gently sloping surface 453 of second greatly sloped side 252 that slips over fixed block 2 when the 5th greatly sloped side 451 and the 7th greatly sloped side 461 of revolving part 4 and the 4th greatly sloped side 262 and revolving part 4 and the 4th gently sloping surface 463 insert first gently sloping surfaces 253 and second gently sloping surface 263, unclamp hand, when first greatly sloped side 251 that slips into fixed block 2 fully when the 6th greatly sloped side 452 and the 8th greatly sloped side 462 of revolving part 4 and the 3rd greatly sloped side 261, the lock key 12 of the just corresponding hinge axis 1 of grafting keyway 42 of revolving part 4, under the compressing power of Returnning spring 6, the grafting keyway 42 of revolving part 4 embedding again returns the lock key 12 of hinge axis 1.This electronic equipment can be in the fine closure of closed state like this.
First outer side surface 264 on first inner side surface, 254 to the second mountain peaks 26 on first mountain peak 25 is more away from hinge axis 1, and first inner side surface 254 on first mountain peak 25 coats first outer side surface, 264 parts on second mountain peak 26, the annular length of first inner side surface 264 on first mountain peak 25 is greater than the annular length of first outer side surface 264 on second mountain peak 26, and the lid that can guarantee the folding electron device is like this realized upset greater than 180 ° with respect to body at first direction.
It is pointed out that the utility model hinge structure not only is confined to above-described concrete structure.
