1 shows an electronic 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 can rotate relative to the body 12 about the axis A.

Referring to FIG. 2 and FIG. 3 , the hinge structure 100 includes a first connecting member 40 , a second connecting member 50 , and a pivoting assembly 60 pivotally connecting the first connecting member 40 and the second connecting member 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 connecting member 40 is fixedly connected to the cover 11 of the electronic device 200. The second connecting member 50 is fixedly connected to the body 12 of the electronic device 200. Of course, the first connector 40 can also be connected to the electronic device 200. The body 12 is 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 41. Mounting holes 411, 421, and 431 are respectively formed in the main body 41 and the connecting portions 42 and 43. 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 penetrating the flat plate portion 51 and the annular portion 52. A plurality of mounting holes (not shown) are defined 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 defined 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 rotating 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 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 together with the first connecting member 40. The end of the shaft portion 614 has a plurality of tangential planes (not shown) such that the lateral cross section of the end of the shaft portion 614 is shaped. 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 one end of the sleeve 62. One end of the sleeve 62 is formed with two clamping tabs 622 for engaging the slot 6121 of the first connecting member 40 to make the sleeve 62 non-rotatable relative to the rotating shaft 61, thereby making the sleeve The barrel 62 is non-rotatable relative to the first connector 40. The sleeve 62 also has a through hole 623 extending through the side wall thereof. In this embodiment, the sleeve 62 can be elastically deformed.

The friction plate 63 is provided with a plurality of oil holes 631 for injecting lubricating oil to reduce the friction between the rotating shaft 61 and the positioning collar 64.

The inner ring edge of the positioning collar 64 protrudes toward the center of the circle to form a two-symmetric positioning protrusion 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 retaining opening 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.

A through hole 651 is defined in the center of the limiting member 65. The shape of the through hole 651 corresponds to the transverse cross-sectional shape of the end 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 shaft portion 614 of the rotating shaft 61 is sequentially inserted into the sleeve 62, the friction plate 63, The collar 64, the second connecting member 50 and the limiting member 65 are positioned. At this time, the retaining tab 622 of the sleeve 62 is caught in the slot 6111 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, and the rotation of the cover 11 is driven. The first connecting member 40 rotates to drive 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 6141 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 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 torsion without the need to provide 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 component can be mounted on the connecting portions 42 and 43 of the first connecting member 40, so that the electronic device 200 can simultaneously open and close the cover 11 relative to the body 12. In addition, the annular groove portion 6141 may not be disposed 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 also be achieved by elastic deformation of the positioning collar 64. In addition, the positioning collar 64 can be disposed in the sleeve 62 And being fixed to the second connecting member 50, the positioning protrusion 641 is formed on the edge of the positioning collar 64.

It can be understood that the hinge structure 100 of the present invention can be used to realize the opening and closing of the cover 11 of the electronic device 200 relative to the body 12.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
