Referring to Figure 3, the pivot 31 has a non-circular cross section. One end is formed with a disc-shaped flange portion 311, and the other end is provided with an annular card slot 312. Referring to FIG. 4 together, the fixing bracket 32 includes a first frame body 320, a second frame body 325 and a rivet 329. The body 320 includes a fixing plate 321 and a supporting plate 322 extending vertically from the side of the fixing plate 321 . The fixing plate 0 321 is provided with a plurality of fixing holes 3211. A circular pivot hole 3221 is defined in an end portion of the support plate 322 away from the fixing plate 321 . A locking hole 3222 is defined in the middle portion, and a riveting hole 3223 is defined in an end portion of the fixing plate 321 . The second frame 325 has a structure similar to that of the first frame 321 except that the size of the fixing plate 3251 is smaller than the size of the fixing plate 321 of the first frame 321 . The rivet 329 is used to secure the first frame 320 and the second frame 325 together. The rotating bracket 33 includes a pivoting portion 331 and a first connecting portion 332 and a second connecting portion 333 respectively extending from the two ends of the pivoting portion 331. The pivoting portion 331 is deformed along the axial direction thereof to cooperate with the pivot 31. A fixing hole 3321 is defined in the connecting portion 332 of the first portion of the first connecting portion 332. The second connecting portion 333 defines a fixing hole 3331. « The stopper 34 includes a disk-shaped body 341. The center of the body 341 defines a deformation hole 342 which cooperates with the pivot 31, and an arcuate limiting block 343 is formed on the side wall. A plurality of oil grooves 344 are also formed on the end surface of the body 341. The fixing member 35 includes a substantially disk-shaped pivoting portion 351 and a limiting portion 352 extending outwardly from one end of the rotating portion 351. In this embodiment, the limiting portion 352 is substantially a triangular protrusion. And the thickness of the bump is larger than the ❹ pivot portion 351. A circular shaft hole 3511 is defined in the center of the pivoting portion 351, and two opposite positioning protrusions 3512 are formed on the side wall around the shaft hole 3511. A plurality of oil grooves 3513 are also formed on the end surface of the pivoting portion 351. A protrusion 3521 extends from the limiting portion 352. The rotary positioning member 36 is substantially disk-shaped, and has a deformation hole 361 which is engaged with the pivot shaft 31 at the center thereof. One of the end faces of the rotary positioning member 36 is provided with two opposite positioning grooves 362 for engaging with the positioning protrusions 3512 of the fixing member 35. A plurality of oil grooves 363 are also formed in the end surface of the rotary positioning member 36. The shrapnel group 37 is formed by laminating a plurality of disc-shaped shrapnels. A circular through hole 3811 is defined in the center of the friction plate 381, and a plurality of oil grooves 3812 are further formed on the end surface thereof. A deformation hole 3821 is formed in the center of the gasket 382 to cooperate with the boring shaft 31. When the hinge structure 30 is assembled, one end of the pivot 31 is provided with a slot 312 passing through a friction plate 381, a pivot hole 3221 on the first frame 320, a pivot hole 3252 on the second frame 325, and another a friction plate 381, a deformation hole 342 on the limiting member 201016105 34, a shaft hole 3511 of the fixing member 35, a 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, The snap ring 39 is then snapped into the slot 312 of the pivot 31, at which point the spring pack 37 will exert axial pressure on the components on the pivot 31. The rivet 329 is then passed through the staking holes 3223 of the first frame 320 and the staking holes 3253 of the second frame 325 to fix the first frame 320 and the second frame 325 together. Then, the protrusions 3521 of the fixing member 35 are inserted into the engaging holes 3222 of the first frame 320 and the engaging holes 3254 of the second frame 325. Referring to FIG. 2 to FIG. 4 , when the hinge structure 30 is used, the first connecting portion 332 of the rotating bracket 33 is rotated in a direction away from the fixing bracket 32 , and the pivot 31 is rotated by the rotating bracket 33 to drive the pivot. The limiting member 34 and the rotating positioning member 36 on the shaft 31 rotate. When the limiting block 343 on the limiting member 34 abuts against the limiting portion 352 of the fixing member 35, the rotating bracket 33 cannot continue to rotate. At this time, the rotating bracket 33 is at the maximum opening angle with respect to the fixed bracket 32. In this process, the rotation of the rotary bracket 33 can be stopped at any position, thereby stopping the rotary bracket 33 at an arbitrary position. Then, the first connecting portion 332 of the rotating bracket 33 is rotated in the direction of the fixed bracket 32, and the pivot 31 is rotated by the rotating bracket 33 to drive the limiting member 34 and the rotating positioning member 36 on the pivot 31. Rotation, because the rotation positioning member 36 is subjected to the axial elastic force of the elastic piece group 37, the positioning groove 362 on the rotation positioning member 36 can be fastened to the positioning protrusion 3512 of the fixing member 35, so that the rotating bracket 33 is relatively fixed. The bracket 32 is positioned. When the hinge structure 30 is applied to the 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 relative to the body or the electric power can be made in 201016105. The cover of the sub-device is automatically locked with the body during the closing process. • Since the hinge structure 30 only needs to pass the pivot shaft 31 through a friction plate 381, a fixing bracket 32, another friction plate 381, a limit member %, a fixing member %, a rotation positioning member 36, a spring piece group 37, a whole piece 382, and After the bracket 33 is rotated, the t-ring % is inserted into the slot 312 of the pivot 31 to complete the assembly. Moreover, after the card 39 is snapped into the slot 312 of the pivot 31, the spring group 37 can be scheduled without any adjustment. The axial pressure, so the hinge structure | has a higher assembly efficiency. The card slot 312 on the pivot 31 is easier to machine than the threaded portion on the general pole axis. This reduces the manufacturing cost of the hinge structure. It can be understood that the hinge structure 3 can also include only the planting shaft 31, the fixing bracket 32, the rotating bracket 33, the elastic piece group 37 and the snap ring, and the corresponding limiting element structure is disposed on the rotating bracket 33 and the fixing bracket 32. To limit the rotation angle of the rotating bracket 33 relative to the fixing bracket 32, if a limiting slot is formed in the fixing bracket%, a limiting jaw protrusion matching 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 position of the fixing bracket 32, the rotating bracket 33 and the elastic piece group 37 on the pivot 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 pivot shaft 31 and the snap ring 39. between. It can be understood that the positioning positioning groove 362 of the hinge structure 30 can not form the positioning groove 362, and a plurality of positioning protrusions can be formed, and then a plurality of positioning grooves can be 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 can also be correspondingly arranged one, three or more, thereby increasing the positioning position of the rotating bracket 33 during the rotation of 201016105. . 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.
