They include a body and a cover, and the body and the cover are borrowed. The hinged chain structure is hinged together to open or close the cover relative to the body. A magnetic hinge structure is disposed in a first stable state or a second stable state, and includes a jacket, a rotating shaft, a fixed magnetic component and a movable magnetic component, wherein the outer casing has a cavity in which the rotating shaft is disposed in the cavity, and the fixed magnetic component is fixed on the outer casing In the cavity, the movable magnetic component is disposed in the cavity and is sleeved with the cavity to rotate the movable magnetic component about the rotating shaft, the movable magnetic component is disposed in pairs with the fixed magnetic component, and the movable magnetic component is coupled with the fixed magnetic component. The polar phase faces; when the magnetic hinge structure is positioned in the first stable state, the movable magnetic element is located on one side of the fixed magnetic element, and when the magnetic hinge structure is positioned in the second stable state, the movable magnetic element is located on the other side of the fixed magnetic element. However, in electronic devices such as notebook computers and handheld game consoles, the display screen is generally disposed in the cover body. 'Users often need to adjust the relative position of the cover body and the body according to different viewing angles, and hope that the two components can be in any relative position. Stay 'read' can be operated at any position without shaking. In the above magnetic Qin chain structure, the movable magnetic element and the fixed magnetic element face at the same position with the same pole 201014510, so that the cover body and the body are positioned in the two stable states, and the positioning cannot be stabilized, and it is difficult to achieve free positioning. SUMMARY OF THE INVENTION It is necessary to provide a magnetic hinge that can be freely positioned in view of the above content chain structure. A magnetic hinge structure includes a fixing component, a rotating component, a rotating shaft and a fastener.

The magnetic hinge structure generates an attractive force by the opposite relationship between the first magnetic element and the second magnetic element, and generates a frictional force between the fixed component and the rotating component, thereby generating a friction torque, and the rotating component is stable relative to the fixed component. The crucible stays in any position, so the above magnetic hinge structure can be freely positioned.

The abutting surface 325 is provided with a circular through hole 3252 extending from the abutting surface 325 in the axial direction of the fixing portion 324 toward the inside thereof and communicating with the through hole 3232. The second magnetic element 34 has a cylindrical shape, and a circular through hole 342 is defined in the center thereof. The magnetic element 34 is sleeved on the rotating shaft 10 through the through hole 342. The second magnetic element 34 includes a third side 344 and a fourth side 346 opposite the third side 344, wherein the third side 344 is an S pole and the fourth side 346 is an N pole. The third side 344 is opposite to the second side 246 第二 of the second magnetic element 24, so that the third side 344 and the second side 246 are opposite in polarity.

Fixing.=60 sets are set on the rotating shaft 5〇, and the rotating component is rotatably sleeved on the rotating shaft. The fastener 80 is disposed at the end of the rotating shaft 50. The difference is that: the fixed component 60 includes two magnetic components 64, and the rotating component includes two magnetic components 74. The inner wall of the mounting hole 62 is provided with two first clamping protrusions. 6235, which is used for holding two first magnetic component materials, and two inner clamping protrusions are provided on the inner wall of the through hole 7232 of the bracket 72 for holding the two second magnetic components 74. It can be understood that the first friction plates 26, 66 and the second friction plate %, % material are not limited to the other magnetic conductive materials, and may be other magnetic conductive materials or non-magnetic materials. When the materials of the first friction plates 26 and 66 and the second friction plates % and 76 are non-magnetic materials, the magnetic field of the first magnetic element 2 *, the material, and the first magnetic component 1 , 34 , 74 can be penetrated. A friction plate 26, 66 and the first friction plates 36, 76 may be used. It can be understood that the magnetic hinge structure 1〇〇, 2〇〇 is not limited to include the first friction plate 26 and the second friction plate 36, and may not include the first friction plate %, 66 and the second friction plate 36, 76. The first magnetic elements 24, 64 are directly abutted against the second magnetic elements 34, 74, or the fixed brackets 22, 62 are directly offset by the rotating brackets 2 72. In addition, the abutting faces of the first friction plate and the second friction plates 36, 76 that abut each other may have a certain inclination with respect to the axial direction, and only between the first friction plates 26, 66 and the second friction plates 36, 76 The frictional force generated by the frictional force in the axial direction of the rotating shafts 10, 50 can overcome the moment generated by the axial force of the rotating shafts 1 and 50. Correspondingly, when the first magnetic elements 24, 64 and the second magnetic elements 34, 74 and the fixing brackets 22, 12 201014510 62 directly abut against the rotating brackets 32, 72, the abutting surface thereof may have a certain inclination. In addition, when the magnetic hinge structure 1〇〇, 2〇〇 is applied to an electronic device such as a liquid crystal display or a pen computer, the frictional force generated by the frictional force in the axial direction of the rotating shaft 10, 50 should also overcome the display screen. Heavy torque. ❹ It can be understood that the number of the first magnetic elements 24 and 64 and the second magnetic elements 34 and 2 is not limited to one or two, and may be three or more, and only the first magnetic element 24 64 and the second magnetic element are required. 34, 74 can be opposite with extreme extremes. And the 'first magnetic element 24, 64 and the second 34, 74 magnetic element are not limited to the first friction plate 26, 66 and the second friction plate 36, 76 to fix the solid 22, 62 and the second bracket 32, 72 The 'can also be used in other ways', for example, the first magnetic element 24, 64 and the second magnetic: 34, 74 can be respectively provided with a card block, the first bracket 22, 62 and the first bracket 32, 72 The inside is separately provided with a card slot that cooperates with the card block. It is understood that the 4G and 8G are not limited to the circlip, and can be replaced by a screw. If the nut is fixed on the 1G and 5G, the fasteners 40 and 80 can be prevented from falling off by welding or riveting. It is proposed that the present invention has indeed met the requirements of the invention patent, and is legally and kissed. However, the above is only the preferred embodiment of the present invention to limit the scope of the patent application of the present invention. Anyone who is familiar with the case π shall be covered by the spirit of the present invention within the scope of the following patent application. 6 [Simple diagram of the diagram] Figure. 1 is a perspective exploded view of a magnetic hinge structure according to Embodiment 1 of the present invention. 13 201014510 • FIG. 2 is a perspective exploded view of the magnetic hinge structure of FIG. 1 in the opposite direction.
