[0020] A deformation hole 3821 is formed in the center of the cymbal 382 to cooperate with the pivot shaft 31. [0021] When the hinge structure 30 is assembled, the pivot 31 is opened with one end of the slot 312 passing through a friction plate 381, a pivot hole 3221 on the first frame 320, and a pivot hole on the second frame 325. 3252, the other friction plate 381, the deformation hole 342 on the limiting member 34, the shaft hole 3511 of the fixing member 35, the deformation hole 361 of the rotation positioning member 36, the elastic piece group 37, the spacer 382 and the deformation hole 3311 of the rotating bracket 33 Thereafter, the snap ring 39 is snapped into the slot 312 of the pivot 31, at which time the spring pack 37 will exert axial pressure on the components on the pivot 31.

Thereafter, the first connecting portion 332 of the rotating bracket 33 is rotated in the direction of the adjacent fixing bracket 32. The lifter 31 will rotate under the rotation of the rotating bracket 33, thereby driving the limiting member 34 and the rotating positioning member 36 on the spool 31. Rotation, due to the rotation of 097138110, the positioning member 36 is subjected to the axial elastic force of the shrapnel group 37, so that the rotation of the form number A0101 is also 8th page / a total of 18 pages 100331012 Bu 0 丄 force 3815 100 August 24, according to the replacement page The positioning groove 362 of the position member 36 is fastened to the positioning protrusion 3512 of the fixing member 35 to position the rotating bracket 33 relative to the fixing bracket 32. [0023] When the hinge structure 30 is applied to an electronic device, the rotating bracket 33 and the fixing bracket 32 are respectively connected to the cover body and the body of the electronic device, so that the cover of the electronic device can be opened at a certain angle with respect to the body. The cover of the electronic device can be automatically locked with the body during the closing process. [0024] Since the hinge structure 30 only needs to pass the pivot shaft 31 through a friction plate 381, the fixing bracket 32, the other friction plate 381, the limiting member 34, the fixing member 35, the rotating positioning member 36, the elastic piece group 37, the gasket After the 382 and the rotating bracket 33 are rotated, the snap ring 39 is inserted into the slot 312 of the pivot 31 to complete the assembly, and after the snap ring 39 is engaged in the slot 312 of the pivot 31, the spring pack can be adjusted without adjustment. The predetermined axial pressure is generated, so that the hinge structure 30 has a high assembly efficiency. Further, the card slot 312 on the frame shaft 31 is easier to process than the thread on the general pivot, which reduces the manufacturing cost of the hinge structure. [0025] It can be understood that the hinge structure 30 can also include only the pivot 31, the fixing bracket 32' rotating bracket 33, the elastic piece group 37 and the snap ring 39, and the corresponding limit is set on the rotating bracket 33 and the fixing bracket 32. The element structure is used to limit the rotation angle of the rotating bracket 33 relative to the fixing bracket 32. For example, a limiting slot is formed in the fixing bracket 32, and a limiting protrusion matched with the limiting slot is disposed on the rotating bracket 33. The shrapnel group 37 can also be replaced by other elastic members such as springs or the like. In addition, the positions of the fixing bracket 32, the rotating bracket 33 and the elastic piece group 37 on the cymbal shaft 31 can be changed, and the fixing bracket 32, the rotating bracket 33 and the elastic piece group 37 are located at the flange portion 311 of the cymbal shaft 31 and the snap ring 39. between. It can be understood that the rotation positioning member 36 of the hinge structure 30 may not form 097138110. Form No. A0101 Page 9/18 pages 1003310121-0 1353815 On August 24, 100, the groove 362 is positioned by the replacement page, and A plurality of positioning protrusions are formed, and then a plurality of positioning grooves are formed on the fixing member 35 to cooperate with the plurality of positioning protrusions. In addition, the positioning groove 362 on the rotating positioning member 36 and the positioning protrusion 3512 on the fixing member 35 may be correspondingly arranged one, three or more, thereby increasing the positioning position of the rotating bracket 33 during the rotation. [0027] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
