One end of the pivot is fixed to the bracket, and the other end is fixed by the fixed seat, the friction plate, the fixed cam, the rotating cam, the elastic piece, and the piece is fixed at the end of the pivot, so that the money is fixed, the friction is: the mutual wheel, the rotating cam, The shrapnel group and the flat shim group cannot be pivoted, and (5) the rotating cam is not pivotally mounted on the cabinet shaft, and the fixing cam is fixed to the fixing seat. In the case of a chain-foamed hinge structure, the number of components is large, making the hinge == more material cost and processing cost. The simpler = chain structure is intended to provide a pivotal assembly of a small number of components and a structure of the first package, the second connector and the pivotal member. The pivoting assembly includes a rotating shaft that is non-201023725 rotatably coupled to the first connecting member, a sleeve that is fixed relative to the first connecting member, and a positioning collar that is fixed relative to the second connecting member. The sleeve is sleeved on the rotating shaft, and the positioning collar is rotatably disposed on the sleeve.

The positioning protrusion is inserted into the positioning hole to keep the first connecting member and the second connecting member relatively stable, and at least one of the sleeve and the positioning collar is elastically deformed by the external force, so that the positioning protrusion can be from the positioning hole. Sliding out to make the first connecting member and the second connecting member relatively rotatable. In the above hinge structure, at least one of the sleeve or the positioning collar is elastically deformed, so that the positioning hole of the sleeve cooperates with the positioning protrusion of the positioning collar to realize the rotational positioning, and the elastic group is not required to provide the elastic force. The hinge structure can be rotationally positioned. Therefore, the number of the above-mentioned hinge structural components is small, and the components of the above-mentioned hinge structure are relatively simple, thereby facilitating assembly and manufacture, thereby reducing production costs. [Embodiment] The hinge structure of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. 1 shows an electrical sub-device 200 equipped with a hinge structure 100 of an embodiment of the present invention, which includes a cover 11 and a body 12. The hinge structure 100 is used to pivot the cover 11 and the body 12 such that the cover 11 of the electronic device 200 is rotatable relative to the body 12 about the axis A. 2 and FIG. 3, the hinge structure 100 includes a first connector 40, a second connector 50, and a pivot assembly 60 pivotally connecting the first connector 40 and the second connector 50. The pivoting assembly 60 is disposed in the middle of the first connecting member 40 and perpendicular to the first connecting member 40. The first connector 40 is fixedly coupled to the cover 11 of the electronic device 200. The second connector 50 is fixedly connected to the body 12 of the electronic device 200. Of course, the first connector 40 can be connected to the body 12 of the electronic device 200 201023725 , and the second connector 50 can be connected to the cover 11 of the electronic device 200 . The first connecting member 40 has a substantially T-shape and has a body 41 and connecting portions 42, 43 extending symmetrically along both sides of the body and the body 41. Mounting holes 411, 421, and 431 are formed in the main body 41 and the connecting portions 42, 43 respectively. The mounting holes 421, 431 are coaxially disposed, and their axes intersect perpendicularly to the axis of the mounting hole 411. The second connecting member 50 includes a flat plate portion 51, an annular portion 52 formed in a central portion of the flat plate portion 51 and extending from one surface of the flat plate portion 51, and a limiting groove formed on the other surface of the flat plate portion 51 and opposite to the annular portion 52. 53 and a through hole 54 extending through the flat portion 51 and the annular portion 52. A plurality of mounting holes (not shown) are formed in the flat portion 51 to fix the second connecting member 50 to the body 12 of the electronic device 200. Two latching openings 521 are formed in the annular portion 52. The limiting groove 53 is substantially circular and has two limiting portions 531. The pivoting assembly 60 includes a rotating shaft 61, a sleeve 62, a friction plate 63, a positioning collar 64 and a limiting member 65. The rotary shaft 61 includes a flange 612, a mounting portion 613 extending from the flange 612 in the axial direction toward both ends, and a shaft portion 614. Two flanges 6121 are defined in the flange 612. The cross-sectional shape of the mounting portion 613 corresponds to the shape of the φ mounting hole 411 of the first connecting member 40, so that the mounting portion 613 is locked in the mounting hole 411, and the rotating shaft 61 can rotate with the first connecting member 40. . The end of the shaft portion 614 has a plurality of tangential planes (not shown) to shape the transverse section of the end of the shaft portion 614. An annular groove 6141 adjacent to the flange 612 is also defined in the shaft portion 614. Of course, the rotating shaft 61 can be integrally formed with the body 41 of the first connecting member 40. Two positioning holes 621 are defined in the sidewall of the sleeve 62. In this embodiment, the positioning hole 621 is a notch formed at the end of the sleeve 62. The sleeve 62 is formed at the end with two latching tabs 622 for engaging the slot 6121 of the first connector 40 to make the sleeve 62 non-rotatable relative to the rotating shaft 61, thereby making the sleeve 201023725 It is non-rotatable with respect to the first connecting member 40. The sleeve 62 also has a through hole 623 extending through the side wall thereof. In this embodiment, the sleeve 62 can be elasticized and deformed. The friction plate 63 is provided with a plurality of oil holes 631 for injecting lubricating oil to reduce friction between the rotating shaft 61 and the positioning collar 64. The inner ring edge of the positioning collar 64 projects toward the center of the circle to form a two-symmetric positioning projection 641. The positioning protrusion 641 of the positioning collar 64 is used for holding the clamping opening 521 of the second connecting member 50, so that the positioning collar 64 is non-rotatable relative to the second connecting member 50, and at the same time, the positioning protrusion 641 is engaged. The latching port 521 of the second connecting member 50 is then engaged with the positioning hole 621 of the sleeve 62. Of course, the positioning collar 64 can also be made non-rotatable relative to the first connector 40, while the sleeve 62 is non-rotatable relative to the second connector 50. The through hole 651 is defined in the center of the limiting member 65, and the shape of the through hole 651 corresponds to the transverse sectional shape of the end portion of the shaft portion 614 of the rotating shaft 61. A limiting protrusion 652 is protruded from the edge of the limiting member 65. The limiting protrusion 652 is configured to cooperate with the limiting portion 531 of the limiting groove 53 to limit the rotation angle of the hinge structure 100. Referring to FIG. 4 and FIG. 5 simultaneously, the mounting portion 613 of the rotating shaft 61 is fixed in the mounting hole 411 of the first connecting member 40, and the φ shaft portion 614 of the rotating shaft 61 is sequentially inserted into the sleeve 62 and the friction plate. 63. The positioning collar 64, the second connecting member 50 and the limiting member 65. At this time, the retaining tab 622 of the sleeve 62 is caught in the slot 6121 of the rotating shaft 61, and the sleeve 62 is sleeved on the rotating shaft 61, so that the sleeve 62 can be elastically deformed toward the annular groove 6141; The positioning protrusion 641 of the ring 64 passes through the holding hole 521 of the second connecting member 50 and is caught in the positioning hole 621 of the sleeve 62. The limiting member 65 is received in the limiting slot 53 of the second connecting member 50. The limiting protrusion 652 of the limiting member 65 abuts against one of the limiting portions 531 of the limiting slot 53. In use, the cover 11 of the electronic device 200 is pulled to rotate the cover 11 relative to the body 12 of the electronic device 200. At this time, the rotation of the cover 11 drives the 201023725 to rotate the first connecting member 40, thereby driving the rotating shaft 61 to rotate. Since the sleeve 62 is non-rotatable relative to the rotating shaft 61, and the sleeve 62 is elastically deformable toward the annular groove '611 of the rotating shaft 61, the positioning collar 64 is non-rotatable relative to the second connecting member 50, and thus when the rotating shaft 61 rotates The positioning protrusion 641 of the positioning collar 64 slides out of the positioning hole 621 of the sleeve 62 and abuts against the surface of the sleeve 62 to elastically deform the sleeve 62. When the rotating shaft 61 is rotated to a certain angle, the positioning protrusion 641 of the positioning collar 64 is again snapped into the positioning hole 621 of the sleeve 62 to realize the rotational positioning, and at this time, the sleeve 62 is restored to deformation. When the angle is rotated again, the limiting protrusion 652 of the limiting member 65 abuts against the limiting portion 531 of the limiting position groove 53 to prevent the hinge structure 100 from further rotating. In the hinge structure 100 of the electronic device 200, the positioning protrusion 641 of the positioning collar 64 cooperates with the positioning hole 621 of the sleeve 62, and since the shaft portion 614 has the annular groove 6141, the sleeve 62 can be directed toward the rotating shaft 61. The direction of the annular groove 6141 is elastically deformed to realize the rotational positioning when the sleeve 62 is engaged with the positioning collar 64. It is no longer necessary to provide the elastic group to provide the elastic force so that the hinge structure 100 can be rotationally positioned, and there is no need to provide a fixed cam and a rotating cam. To achieve positioning. In addition, the friction between the positioning collar 64 and the sleeve 62 provides a stable torque of φ without the need for a spacer set. Therefore, the number of components of the hinge structure 100 is small, and the components of the hinge structure 100 are relatively simple in structure, thereby facilitating assembly and manufacture, thereby reducing production costs. Of course, the rotating assembly can be mounted on the connecting portions 42, 43 of the first connector 40, so that the electronic device 200 can simultaneously open and close the cover 11 relative to the body 12. Further, the annular portion 6141 may not be provided on the shaft portion 614 such that the diameter of the sleeve 62 is slightly larger than the diameter of the shaft portion 614. It can be understood that the positioning hole 621 on the sleeve 62 can also be a through hole or a groove or the like. In addition, the rotational positioning of the hinge structure 100 can be similarly achieved by elastic deformation of the positioning collar 64. In addition, the positioning collar 64 can be disposed in the sleeve 62 11 201023725 and fixed to the edge of the second connecting member 64. 50. Forming the positioning protrusion 641 on the positioning collar It can be understood that the hinge structure 100 of the present invention can be used to realize the opening and closing of the body 12. Throughout the electronic equipment / in summary, the invention is in line with the financial assets, and the patent application is filed. However, 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.
