Description of the invention: [Technical Field of the Invention] [0001] The present invention relates to a hinge structure, and more particularly to a hinge structure suitable for an electronic device. [Prior Art] [0002] In an electronic device such as a notebook computer or a handheld game machine, it is often necessary to realize relative rotation of two components by a hinge structure, and it is desirable that the two components can stay at any relative positions so as to be able to be in any position. Operate it without shaking. A conventional hinge structure includes a rotating member, a follower, a cam, and a fixing member that is rotatable relative to the fixed member and is provided with an elastic group on an axis of relative rotation thereof. The elastic piece group includes a plurality of pairs of elastic pieces, each of which is substantially a circular disk-shaped piece having a central opening, that is, a central portion thereof protrudes toward one side in the axial direction thereof, and has elasticity. Each pair of elastic pieces is disposed in a back direction, that is, the protruding portions of the two elastic pieces are disposed together. The elastic piece of the elastic group is used to provide an axial force so that the rotating member, the follower, the cam, and the fixed member are pressed into close contact with each other and cannot be freely rotated. The axial force provided by the elastic group provides a frictional moment of relative rotation between the follower and the cam, so that the rotating component stays at any position when rotating relative to the fixing component, and the follower and the cam are respectively provided with each other. The convex portion and the concave portion are fitted to stabilize the rotating member with respect to the fixing member at a certain position. [0004] However, in the above hinge structure, each of the elastic pieces provides a relatively small axial force, so a plurality of elastic pieces are required, which results in a complicated structure and complicated assembly. 097126435 Form No. Α0101 Page 5 of 18 1003399705-0 1356671 100.

October 2b modified replacement page wiper 1 5 one of the outer end face is open with two An inclined wall 1 542 is formed on each of the two sides of the inner wall of the positioning groove 154 which is formed on the two sides of the through hole 152. The other outer end surface of the limiting friction plate 15 is formed with two positioning posts 156 for inserting into the pin holes 1444 of the fixing bracket 11 so that the limiting friction plates 15 and the fixing bracket 11 are non-rotatably connect them. The clamping block 16 includes a resisting portion 162, a fitting portion 164 extending from the end of the abutting portion 162, and a positioning protrusion 166 extending from the other end of the abutting portion 162. The positioning protrusion 166 includes two inclined surface portions 1662 (see FIG. 2) and a flat portion 1 664 (see FIG. 2). The positioning protrusion 166 corresponds to the positioning groove 154, and is used for the deformable member 17 relative to the limiting friction plate 丨5. When rotated, the positioning groove 154 is slid out by the inclined wall 1542 of the positioning groove 154 and the deformable member 17 is pressed. The deformable member 17 is substantially in the form of a disk, and includes a body 172 and two bosses 174 extending from the same end surface of the body 172. The end faces of the bosses 174 are flat to maintain the bucks 18 when assembled. Good contact. The center of the deformable member 17 is further provided with a non-circular deformation hole 176. The two sides of the deformation hole 176 are provided with two latching grooves 178 for engaging the fitting portion 164 of the positioning block 16. Therein, it is engaged with the deformable member 17. The fastener 19 is a locknut, which is generally a hexagonal prism, and has a screw hole 192 at the center thereof. The thread 1264 of the shaft portion 126 of the shaft 12 cooperates with the screw hole 192 of the fastener 19 to detach the fastener 19. The ground is fixed to the rotating shaft 12, thereby preventing the friction plate 13, the fixed bracket π, the limit friction plate 15, the deformable member 17, and the spacer 18 from coming off the rotating shaft 12. The fastener 19 includes a lock portion 194 (see Fig. 2) for preventing the fastener 19 from being loosened by being pressed after being screwed to the rotary shaft 12.

Page 8 of 18 1003399705-0 1356671 • October 28, 100 Correction replacement page The number of projections provided on the end face of the fastener 19 is set. [0018] Please refer to FIG. 3 and FIG. 4 simultaneously. When the hinge structure 100 is assembled, the engaging portion 124 of the rotating shaft 12 is first inserted into the engaging hole 1142 of the rotating bracket 11, so that the rotating shaft 12 and the rotating bracket 11 are stuck. Then, the fitting portions 164 of the two positioning blocks 16 are respectively embedded in the two engaging grooves 178 of the deformable member 17; then the friction plate 13, the fixing bracket 11, the limiting friction plate 15, and the positioning block 16 are embedded. The deformable member 17 and the spacer 18 are sequentially sleeved on the shaft portion 126 of the rotating shaft 12, and the positioning post 156 of the limiting friction plate 15 is embedded in the pin hole 1444 of the fixing bracket 11 to make the limiting friction plate 15 and the fixing bracket. 11 is not rotatable relative to each other, and the positioning protrusion 166 of the positioning block 16 is dropped into the positioning groove 154 of the limiting friction plate 15; finally, the fastener 19 is screwed onto the thread 1 264 of the shaft portion 126 of the rotating shaft 12, thereby tightening The firmware 19 is fixed to the rotating shaft 12. [0019] When the force is applied to rotate the rotating bracket 11 relative to the fixed bracket 11, the rotating bracket 11 drives the rotating shaft 12 to rotate, and the deformable member 17, the spacer 18 and the fastener 19 rotate along with the rotating shaft 12 relative to the fixed bracket 14. The positional ribs 15 and the fixing bracket 14 are non-rotatable, and the positioning protrusions 166 of the positioning block 16 embedded in the deformable member 17 start to move along the inclined wall 1 542 of the positioning groove 154 of the limiting friction plate 15 to the limit friction. The sheet body 172 is deformed by the sheet 172 of the deformable member 17 by the abutting portion 162 on the end surface of the sheet 15, and the elastic restoring force generated by the deformation forces the positioning block 16 and the limit friction sheet 15 to be squeezed each other. The pressure generates an axial pressure, which in turn generates a frictional force, thereby forming a frictional moment that allows the rotating bracket 11 to rest at any position relative to the fixed bracket 14. [0020] The hinge structure 100 provides axial pressure by the elastic restoring force generated by the deformation of the deformable member 17, and the deformable member 17 is deformed back to 097126435 as compared with the prior art.

In addition, the positioning block is 16 years old in the deformable member 17, and the interchangeability is good, and only the positioning block 16 can be replaced when worn. [0021] It can be understood that the positioning block 16 can also be provided with one, three or more, and the limiting friction month 15 also has one, three or more positioning grooves 154. The limiting friction plate 丨 5 can also be provided with a plurality of positioning grooves 154 of the number of positioning blocks μ, so that the rotating bracket 11 is maintained at a stable state with respect to the fixed bracket 14 at a plurality of rotation angles such as 12 degrees, 135 degrees, and the like. In addition, the positioning block 16 can be directly fixed to the deformable member 17, or integrally formed therewith.
