The present invention relates to a hinge structure, and more particularly to a modular structure of an electronic device. [Prior Art] [0002] Common electronic devices, such as notebook computers, flip-type mobile phones, and electronic dictionaries, usually need to connect the cover body and the main body by a hinge structure. In the process of using the notebook computer, it is usually required that the cover body can be repositioned at any angle to facilitate the user's operation, which requires a certain friction between the internal components of the hinge structure. [0003] A hinge structure on an electronic device includes a main shaft, a friction member fixed to the main shaft, a follower sleeve that is sleeved on the main shaft and rotatable relative to the main shaft, and a sleeve that is sleeved on the element. The friction member has a friction surface which is a curved surface. The driven member has a driven surface and a limiting groove, and the driven surface is a rotating curved surface abutting on the friction surface of the friction member, and the limiting protrusion is disposed on the bracket, and the limiting protrusion and the limiting member are limited The slot fits to limit the rotational speed of the follower relative to the bracket. The frictional force is generated by the frictional surface between the friction member and the follower, thereby allowing the cover to be stopped at any angle. Further, an elastic member that abuts against the driven member is further disposed on the main shaft, and the elastic member can maintain a certain frictional force after the long-term use of the follower member and the friction member. _ In order to make the connection of the electronic device more secure ‘and to save the space of the connection, usually under the condition of satisfying the structural strength of the money, the two hinge structures are arranged as small as possible at the two ends of the connection. However, the follower and the friction member are sleeved on the main shaft and the elastic member is sleeved on the main shaft, and the sleeve sleeve 09713308# single-numbered surface 1 page 4/18 pages 〇1013008664-0 1361034 101 On January 06, the shuttle replacement page is set on each of the above components, so the sleeve of the hinge structure has a large volume and an inner diameter, which inevitably leads to a larger overall size of the hinge structure, thereby affecting the electronic device. The appearance. If the diameter of the main shaft is reduced to reduce the overall size of the hinge structure, the strength of the main shaft will be reduced, thereby shortening the service life of the hinge structure. SUMMARY OF THE INVENTION [0005] In view of the above circumstances, it is necessary to provide a relatively small-sized and more durable chain structure. [0006] A hinge structure includes a two-rotation assembly and an elastic member disposed between the two rotation assemblies and connected to the two rotation assemblies, the rotation assembly including a main shaft, a sleeve sleeved outside the main shaft, and a sleeve and a sleeve a friction member having a friction portion and a connecting portion protruding from an end surface of the friction portion, the friction portion of the friction member is sleeved on the main shaft, and the connecting portion of the friction member protrudes from the sleeve; Both ends of the elastic member are elastically connected to the two connecting portions of the friction member to abut the friction member and the sleeve. [0007] The elastic member of the hinge structure is disposed outside the rotating component, and the two rotating components share the elastic force of the friction member and the sleeve by sharing an elastic member, thereby reducing the overall volume of the rotating component, thereby The overall volume of the hinge structure is reduced. In addition, when wear occurs between the friction member and the sleeve, the elastic member can maintain the friction member and the sleeve still in a state of mutual abutment, thereby prolonging the service life of the hinge structure. [Embodiment] The hinge structure provided by the embodiment of the present invention will be further described in detail below with reference to the accompanying drawings. 097133G8#单单A〇101 Page 5/18 pages 1013003664-0 1361034 [0009] [0011] [0012] [0112] January 06, 2011, the replacement page, please refer to FIG. 1 ^ - The embodiment of the present invention The drum chain structure provided is set on the flip-flop electronic _ _ 1 on the summer.

In this embodiment, the radial width of the center hole is equivalent to the outer diameter of the first shaft section 211, and the second engaging portion 2517 is a ridge protruding from the hole wall of the center hole 2515. The diameter of one end of the circular table segment 2513 away from the cylindrical segment 2511 is small, the connecting portion 253 is a plate-like structure protruding from the end portion of the circular table segment 2513, and the connecting portion 253 is provided with a connecting hole 2531. [0015] The elastic member 30 is a spiral column spring disposed between the two rotating components 2〇 for connecting the two rotating components 20, and the elastic members 2 have a hook portion 31 at each end thereof, and the hook portion 31 can pass through the connection. The connecting portion 2531 of the portion 253 connects the elastic member 30 to the two friction members 25. Referring to FIG. 1 again, the main body 40 has a first fixing portion 41 and a first protective cover 43 covering the first fixing portion 41. The first fixing portion 41 is provided with a corresponding second through hole 239 on the two sleeves 23. The first screw hole 411, in the embodiment, the first screw hole 411 has eight" through the first through hole 239 of the sleeve 23 through the first fastener 6 and is screwed into the body 4 The screw hole "I" is used to fix the two rotating components 20 to the main body 4. In the embodiment, the first fastener 60 is a screw. The cover 50 has two second fixing portions 51 and a second fixing portion 51. No. 09713308^ A0101 Page 7 of 181013008664-0 1361034 [May 2006, the replacement page of the second protection cover 53 is opened on the second fixing portion 51 and the first passage on the second spindle 21 is opened. The hole 2135 corresponds to the second screw hole 511. In this embodiment, the second screw hole 511 has eight. The second fastener passes through the first through hole 2135 on the main (10) and is screwed into the second cover 50. The screw hole 511 is fixed to the cover (4), and the second fastener is like a screw. Please refer to FIG. 4 as well as the rotation stage. At 20 o'clock, the friction portion 251 of the friction member 25 is first sleeved on the first shaft segment m of the main shaft 21, and at this time, the second engaging portion 2517 is held in the first engaging portion mi to prevent the spindle 21 from being caught. Rotating the friction member 25. The sleeve 23 is sleeved on the main shaft 21 and the friction member 25, and the connecting portion of the friction member 25 is moved out from the second receiving cavity to the outside of the sleeve 23. The friction portion 251 of the friction member 25 is The round table section (5)" is divided into the wall of the second receiving cavity 233, and when the sleeve is corrected to the main pumping (four), the round table section 2513 of the friction member 25 and the wall of the second receiving cavity are torn. Produces friction. When the body is connected to the cover 5, the first fixing portion 41 is placed between the second fixing portions 51 of the cover 50. Then, after the one rotating component 20 is placed on the first fixing portion 41 and the second fixing portion 51, the first fastener 60 passes through the second through hole 239 of the sleeve 23 and is screwed into the first screw of the main body 40. In the hole 411, the second fastener 7 passes through the first through hole 2135 of the main shaft and is screwed into the second screw hole 5丨1 of the cover 50, so that the two rotating components 20 cover the main body 4 and cover 50 connect them. Next, the two hook portions 31 of the elastic member 3 are passed through the two connecting portions 253 of the two friction members 25. Since the distance between the two connecting holes 2531 is larger than the natural length of the elastic member 3, the elastic member 30 is stretched when it is connected between the two friction members 25, so that the friction 09713308# single number AG1()1 is page 8/ A total of 18 pages of 1013008664-0 [0019] is called U34 [^LOl year of January 06 grain protection cover 43 cover on the first fixing portion 51, with the security member 25 and the sleeve 23 closely fit. The most (four) l fixed portion 41, the second (four) covers the hinge structure 1 〇. The elastic member 30 is placed outside the rotating assembly 20, and the same elastic member 30, rotating (four) 2Qp rotating assembly 2 〇 shared rotating assembly 20 does not need to reserve the elastic member 3 〇 empty to reduce the volume of the rotating group (4), and because Only one elastic member is used to reduce the overall (1) of the hinge structure 10. Under the fourth (4) strength requirement, the main shaft 21 is reduced in diameter so that the main material 21 is stepped. The friction member 25 can be sleeved on the shaft shaft having a smaller diameter to save the sleeve 23 from accommodating the friction member. The space of 25 reduces the size of the rotating group (10), making the electronic device using the hinge structure 1 () thinner and having a better appearance. In addition, because of the elastic force of the elastic member 3Q, the friction member 25- is still held against the sleeve 23 after the long-term use of the hinge structure 10 to ensure that the cover 30 can still stay at any angle after a long time of use. [0020] It can be understood that the first engaging portion 2111 and the second engaging portion 2517 can also be other engaging structures, so that the main shaft 21 and the friction member 25 cannot be relatively rotated, for example, the first engaging portion 2111 can be Provided as a ridge, the second engaging portion 2517 is provided as a groove.
