[Embodiment] [0008] A preferred embodiment of the present invention discloses a hinge device 90 that is suitable for use in a portable electronic device such as a mobile phone or a PDA including a body and a cover. In the present embodiment, a mobile phone is taken as an example. [0009] Referring to the first and second figures, the hinge device 90 includes a shaft 1, a cam member 2, a friction reducing body 3, a retaining ring 4, an elastic member 5, and a snap ring 6. [0010] One end of the shaft 1 is provided with a rotation stop portion 10, and the other end is provided with a flange portion 14. A rotating member 12 is located between the rotation stop portion 10 and the flange portion 14, and is connected to the rotation stop portion 10 The rotating member 12 is provided with two convex portions 120 toward one end of the flange portion 14. The top portion of the protruding portion 120 has a top end 122. The rotating member 12 and the flange portion 14 are a shaft portion 13 . The shaft portion 13 is a shaft portion 13 .

September day nuclear replacement of the true body 3 thickness can be slightly larger than the depth of the groove 26, and block The ring 4 is only in contact with the friction reducing body 3, and the thickness of the friction reducing body 3 can also be made equivalent to the depth of the groove 26, so that a part of the end face of the ring 4 is in contact with the friction reducing body 3. The friction reducing body 3 is made of a plastic material such as nylon or polyacetal so that the friction coefficient between the friction reducing body 3 and the retaining ring 4 is smaller than that between the cam member 2 and the retaining ring 4 to reduce friction and thereby reduce energy loss. The striker 4 is a ring that is adjacent to the cam member 2 and is sleeved at the shaft portion 13 of the shaft. [0014] The elastic member 5 is a spiral column-shaped compression spring, and the elastic force of the elastic member 5 is pushed against the cam member 2 to always contact the convex portion 12? [〇〇15] The needle ring 6 is provided with a notch at the edge. a ring that is snapped onto the small shaft portion 13A adjacent to the flange portion 14 of the shaft 1 to abut against the elastic member 5 to prevent the elastic member 5 from coming off the shaft 1, the flange portion 14 preventing the card Ring 6 is released. _] Please refer to the third figure and the fourth figure. When assembling, firstly reduce the friction (4) at the groove 26 of the cam member 2, and then sequentially rotate the cam member 2, the retaining ring 4 and the elastic member 5 from the shaft. One end of the flange portion 1 4 is fitted over the shaft portion 13, and finally the snap ring 6 is caught by the notch on the small shaft portion 13 and abuts against the flange portion 14. After assembly, the convex surface "the cam surface 24 of the member 2 abuts the convex portion 120 of the shaft 1, and the top end 122 is located at the two valleys 240 of the cam member 2, and the friction reducing body 3 ... is out of the end surface of the cam member 2 Contacting one end surface of the duty ring 4, the two ends of the elastic member 5 and the retaining ring 4 and the snap ring top can be pre-stored with a certain elastic force so that the cam member 2 is always in contact with the convex portion 120. The cam member 2 can; The shaft 13 slides linearly and is rotatable relative to the shaft portion 13. [0017] Please refer to the fifth figure 94911836 for producing a single ship 101. The hinge device 9 is used for portable electronic devices. Page 7 of 19 1013353762-0 1378187 On September 18, 101, the shuttle is replacing the page. The portable electronic device includes a body 91 and a cover 92. The hinge device 90 is mounted on the connection portion between the body 91 and the cover 92, and the cam member 2 The locking rib 20 is engaged with the portable electronic device cover 92 and can rotate together with the cover body 92. The shaft 1 is coupled to the portable electronic device body 91 by the rotation preventing portion 10 and fixed relative to the body 91. When the cover body 92 is in the closed state, the top end 122 of the convex portion 120 of the shaft 1 is located in the concave shape of the cam member 2. At 240, the cam member 2 is always in contact with the convex portion 120 under the elastic force of the elastic member 5. At this time, the elastic member 5 has a pre-pressure. [0018] When the cover body 92 is opened, the cover body 92 is opened by an external force. The top end 122 of the convex portion 120 on the rotating member 12 is slid along the cam surface 24 by the concave valley 240, and the cam member 2 linearly slides along the shaft 1 while rotating together with the cover body 92, so that the elastic member 5 is compressed. When the tip 122 reaches the peak 242, the elastic member 5 is compressed to the shortest and accumulates a certain elastic potential energy. When the tip 122 passes over the peak 242, the convex portion 120 automatically slides along the cam surface 24 due to the elastic force of the elastic member 5. The cover body 92 is opened until the top end 122 is at the other valley 240. During this process, the friction reducing body 3 rotates with the cam member 2, and the retaining ring 4 abuts against the friction reducing body 3 and generates mutual axes. To the pressure, and thus the frictional force calculation formula: f frictional pressure is the friction coefficient), since the friction coefficient between the friction reducing body 3 and the retaining ring 4 is smaller than the friction coefficient between the cam member 2 and the retaining ring 4, the friction can be reduced. , thereby reducing energy loss. When closing the cover 92, the hinge device 9 The working principle of 0 is the same as that when it is opened. [0019] It can be understood that the friction reducing body 3 can also be a liquid or emulsion-like lubricating oil, that is, a lubricating oil is injected into the groove 26, and the lubricating oil is rotated in the cam member 2. When an oil film is formed between the cam member 2 and the retaining ring 4, the friction reducing effect can also be achieved; the friction reducing body can also be disposed at the end of the cam member 2, without the 09411836# single number A〇101 8 pages/total 19 pages 1013353762-0 1378187 101 years.
