The outer peripheral wall of the cam 30 has a positioning groove 34 along its axial direction, standing at two =. The positioning groove 34 has an arc shape with an arc of 90 degrees. And in the convex "two parts ^ = through hole 36, the pass 36 A is in the shape of a face, the shape of which is the shape of the shaft portion of the shaft 2 0 0C 0. The spring 40 is a coil spring. Please refer to the In the sixth figure, the rotating member 5 includes a columnar portion η and a spotted position substantially cylindrical, and a second limiting groove 52〇 is opened along the axial direction of the outer circumferential wall. ^ ί f3 is shaped by a shape, and the arc is 9Q degrees. One end of the miscellaneous portion 52 with respect to the engaging portion 54, the lower end, the engaging two == the end opening is i=4, and the receiving hole 522 of the columnar portion 52 is continuous. - the branch B hole 544 The deformation hole is torn and the shaft body diagram, firstly -_. The edge portion 22 is abutted on the separator 1〇4, and the axis is said to be 'the protrusion is then sequentially passed through the cam 3〇 on the shaft portion 24, The through hole % ghost = 〇, the second convex portion of the Xia - side; 522 and the deformation hole 544, and the accommodating hole 40 and the receiving hole of the rotating member 50 are placed in the first - (four) 12. Because the shaft portion 24 is A deforming shaft portion, 9 1376926, cooperates with the through hole 36 of the cam 30 and the deformation hole of the rotating member 544 to define the cam 3〇 and the rotating member 50 to rotate relative to each other. The mating block 32 of the cam 30 and the first portion The first bump of a cylinder 丨2 1〇2 And the second slot 1022 between the card slot 1〇24 cooperates with the '忒 spring 4〇', the end is placed in the receiving hole 522 of the rotating member 5〇, and the other end is abutted on the β wheel 30. Meanwhile, the first The rib 1 2 of the cylinder 12 is fitted into the position groove 34 of the wheel 3 and the limiting groove 520 of the rotating member 50; thereafter, by the clock at the fixing hole 26 of the rotating shaft 2 The component card gj is connected to the body to complete the assembly in the first cylinder 12. The assembly process of the second cylinder 14 is similar to the assembly process of the first cylinder 12, and will not be described in detail herein. The assembled hinge structure 200 is mounted in the folding electronic device 2, and the positioning cylinders 1142 and 1242 of the lower jaw m and the lower body 124 are oppositely disposed adjacent to each other, and the first cylinder of the chain structure 200 is further disposed. The second cylinder is placed in the slot 1240 of the lower body 124, and the two ends of the connecting portion 16 are respectively fitted to the recesses 1148, (10) The cylinder 12 is connected to the lower cover 114, and the second cylinder 14 is connected to the lower body 124. Meanwhile, the two engaging portions 54 of the hinge structure 200 are respectively associated with the positioning cylinders i 142, 124 ^ non-H body 12 and the second miscellaneous 14 other End = min carved grooves disposed with the sleeve through the thread guide 18 41〇, thereby achieving an electrical connection between the cover and the body 12〇 11〇. After the removal, the upper cover 112 is placed on the lower body 114. The upper body 122 is placed on the lower body 124, and the component group is placed on the lower body. In the figure, the cover ug is closed relative to the body 120, and the cams 3G in the first and second parents 14 are respectively inserted into the slots of the sleeve (4), and when opened, please refer to the tenth and tenth drawings. The cover body 11Q, because the 1020, the second block 1022, the third bump 1040, the fourth bump 1〇^ ghost 1>Η2>Η3, the cover body 110 is the first to be described. , for H4 = part of the job, _ rotation, the rotation of the rotation block, the rotation of the mating block 32 in the position of the ninth figure counterclockwise rotation, because the first _ bump 〇 2 ^ 玄 cam 30 bump ι 〇 22 height ' When the matching block η of the cam 3〇 is larger than the first bump 丨022 from the card slot _ 022, and is stuck to the first bump surface and the second bump 〇22, the cover is over the second, the sleeve The rib 1b of the first cylinder 12 of the cylinder 10 is within the cam ^'=4. The limit slot 520 of the same member 50 is relatively rotated by 9 degrees. At this time, the cover body 1 1376926, 9° is restricted by the rib 102 of the first cylinder 12 of the sleeve 1 , and the cam 30 is further rotated, so that the body 110 stays at a 90 degree state. In the 180 degree state T', please refer to the twelfth thirteenth figure, and continue to pull the cover U〇, because the cam 30 in the first cylinder 12 connected to the cover 110 is stuck to the first cylinder 12 The rib 102 is not rotatable, and at this time, the second cylinder 14 connected to the body 120 occurs. The mating block 32 of the cam 30 in the second cylinder 14 slides out of the slot 1044. The height of the fourth bump 104 of the first cylinder 14 is greater than the height of the third bump 1040. The mating block 32 passes over the third bumps 1〇4〇, thereby being caught in the fourth bumps 1〇42 and the third bumps丨〇4〇=card slots 1044. At the same time, the rib 142 of the second cylinder 14 of the sleeve 1 is relatively rotated by 9 degrees in the positioning groove 34 of the slant 30 and the limiting groove 52 of the rotating member 50. At this time, the body|20 is opened 9 degrees with respect to the main body 11〇, and the rib 1〇2 of the first cylinder 12 of the sleeve 1 is restricted. The cam 30 is further rotated, so that the body 120 faces the cover. The body 110 is rotated 90 degrees clockwise at the position of the tenth figure, thereby completing the opening of the cover 11 〇 relative to the body 12 〇 18 degrees. When it is closed, its operation is opposite to the above process and will not be described in detail here. The folding electronic device can be rotated 90 degrees to facilitate viewing of the screen display information. Alternatively, the folding electronic device can be opened (10) degrees from the * to the new machine form (4), thereby combining the straight bar machine and the folding electronic device. The advantages of both devices. It can be understood that the receiving hole 522 of the rotating member 5 can be omitted, so that the elastic member 40 directly abuts against the end wall of the rotating member 50. It can be understood that the shape of the second protrusion 1022, the third protrusion 1040, the fourth protrusion 1042 and the mating block 32 of the cam 30 of the first bump 1020 of the sleeve is not limited to a ladder shape, and In the shape of a cam, the angle of rotation thereof also changes correspondingly according to different shapes. ""# It can be understood that the height of the first bump 1020, the second bump 1022, the third bump 1〇4〇, and the fourth bump 1042 of the sleeve is not limited to H4=H1>H2> H3, which may also be disposed opposite to the height of the first cylinder 12 and the second cylinder 14, so that the first body is opened 9 degrees with respect to the cover, and then the cover is opened 90 degrees with respect to the body. It can be understood that the positioning groove 34 and the limiting groove 520 of the rotating member 50 can omit one of them, and can also limit the rotation angle of the chain structure 2〇〇. It can be understood that the positioning groove 34 of the cam 3, the limiting groove 52 of the rotating member 50 can also be omitted, and only the first bump 1020, the second bump 1022, and the third bump of the sleeve 10 are used. The shape of the mating block 32 of the 1〇4〇, the fourth & block 1042 and the cam 3〇 defines the angle of rotation.
