Compared with the prior art, the pivoting device and the rotating shaft device of the hinge structure can provide two vertical rotations to meet more B requirements of consumers. [Embodiment] A preferred embodiment of the present invention discloses a hinge structure suitable for a folding electronic device such as a notebook computer. In this embodiment, a notebook computer is taken as an example. Referring to FIG. 1 , the hinge structure 10 of the preferred embodiment includes a bracket 12 , two bases 14 , two pivot devices 16 , a plate 18 , and a rotating shaft device (not labeled). The device 16 rotates the hinge structure 10 about a first axis A1 that rotates the hinge structure 10 about a second axis A2. The bracket 12 includes a cylindrical casing 121 and two side flaps 123 symmetrically distributed on both sides of the casing 121. The housing 121 includes a receiving cavity 125. The cross-sectional profile of the receiving cavity 125 is non-circular. The housing 121 has an end opening and the other end of the housing 121 is provided with a stopper 126. The side flaps 123 extend in the axial direction of the vertical housing 121, and have end portions having a bent portion 127 parallel to the axial direction of the housing 121, and a non-circular deformation hole 128 is defined in the center of the bent portion 127. A rectangular recess 129 is defined in the top of each of the 2008 072 s ′′ flank 123. The recess 129 can accommodate a rectangular recess 120 having a slightly concave end. The yoke 120 has elasticity. The width of the recess 129 is slightly smaller than the abutment 120. When mounted, the tab 120 is compressed in the width direction to be engaged in the recess 129. The base 14 includes a pivoting portion 141, a fixing portion 143 and an extending portion 145. The pivoting portion 141 is vertically bent from one end of the fixing portion 143 in one direction, and the extending portion 145 is perpendicular to the other direction from the fixing portion 143. Bend. Two fixing holes 146 are respectively defined in the fixing portion 143 and the extending portion 145, and the base 14 is mounted on the notebook computer through the * mounting hole 146. A pivot hole 147 is defined in the pivoting portion 141. The two pivoting devices 16 each include three spacers 161a, 161b, 161c, a pivot 163, two resilient washers 165, and a nut 167. The pivot shaft 163 includes a deformed shaft portion 1631, a flange portion 1633, a shaft joint portion 1635, and a screw portion 1637 which are sequentially disposed. The diameter at the flange portion 1633 is the largest. The threaded portion 1637 is provided with a crepe pattern. The shaft portion 1635 is partially cut away from a portion of the screw portion 1637 and both sides of the screw portion 1637 are formed, thereby forming a two-section 1369 thereon. The elastic washer 165 has a disk shape, and a deformation hole is formed in the center thereof to cooperate with the cut surface 1369 of the shaft joint portion 1635, and the two elastic washers 165 are opposed to each other. Referring to FIG. 2 and FIG. 3 simultaneously, the deformed shaft portion 1631 of the pivot 163 is inserted into the deformation hole 128 of the bracket 12 so that the pivot 163 and the bracket 12 are not rotatable relative to each other, and the deformation shaft portion 1631 of the pivot 163 and the bracket 12 are deformed. The holes 128 fit. The spacer 161a, the base 14, the spacer 1611?, the two elastic washers 165, and the spacer 161c are sequentially inserted into the pivot 163, and finally the nut 167 is screwed into the screw portion 1637 of the pivot 163 to prevent the spacers 161a, 161b, 161c. , 200807220 ~ The base 14 and the elastic washer 165 are disengaged from the pivot 163. The spacer 161a, the base 14 and the spacer 161b are sleeved on the pivot portion 1635 of the pivot 163. The pivot 163 is rotatable relative to the base 14, and the spacer 161a abuts against the flange portion 1633 of the pivot 163. The two elastic washers 165 are not rotatable relative to the frame shaft 163 because they are provided with deformation holes, which provide an axial force. The support plate 18 is rotatable relative to the bracket 12, and includes a flat plate portion 181. The flat plate portion 181 defines a shaped hole 183 in the center thereof, and the shape of the shaped hole 183 corresponds to the cross-sectional shape of the receiving cavity 125 of the housing 121 of the bracket 12. The flat plate portion 181 is provided with two lugs 185 vertically in one direction and a tab 187 vertically on the other side in the opposite direction. Each of the lugs 185 defines an assembly hole (not shown) through which the support plate 18 can be mounted to the notebook computer. The tab 187 is provided corresponding to the stop 126 of the bracket 12 for limiting the angle of rotation of the bracket 18 relative to the bracket 12. One surface of the flat plate portion 181 is concave, and two convex portions 189 are protruded on the other surface. The convex portions 189 are in contact with the abutting piece 120 at the groove 129 of the bracket 12. Since the notebook computer needs to be opened by the pivot device 16 about the first axis A1 when the φ is more φ, instead of being rotated about the second axis A2 by the hinge device, the tab 120 and the convex portion 189 of the support plate 18 are The mating causes the support plate 18 to remain stable relative to the bracket 12 during opening. The shaft assembly includes a rotating shaft 191, a rotating member 193, a fixing member 195, two elastic pieces 197 and a washer 199. The rotating shaft 191 includes a shaft portion 1911 and a stopping portion 1913, and the rotating shaft 191 defines a through hole 1915 extending through the center thereof. The stop portion 1913 is larger than the shaped hole 183 of the support plate 18 to stop the support plate 18. A central hole (not shown) is defined in the center of the rotating member 193, and includes a shaped portion 1931 to be opposite to the shaped hole 183 of the supporting plate 18, and the rotating member 193 and the supporting plate 18 are not rotatable relative to each other. The opposite end of the deformed portion 1931 of the member 193 has an abutting surface (not shown). The abutting surface is provided with four uniformly distributed protrusions 1933. The fixing member 195 is a columnar body having a sectional shape corresponding to the sectional shape of the accommodating cavity 125 of the housing 121 of the holder 12. A fixing hole 195 is defined in the center of the fixing member 195, and a matching hole 1953 is formed on the mating surface 1951. The projection 1933 of the rotating member 193 cooperates with the recess 1953 of the fixing member 195 to have a distinct positioning at each of the four positions. The elastic piece 197 is an elastic curved piece body having a center hole formed therein. It can be understood that the protrusions 1933 and the recesses 1953 on the rotating member 193 and the fixing member 195 are not limited to four, and may be any number. The two elastic pieces 197 and the fixing member 195 are received in the accommodating cavity 125 of the housing 121 of the bracket 12, and then the rotating shaft 191 is sequentially passed through the shaped hole 183 of the supporting plate 18, the rotating member 193, the fixing member 195, the elastic piece 197 and the washer 199. Finally, one end of the rotating shaft 191 opposite to the stopper 1913 is folded outward to form a 10 retaining portion 1917, thereby preventing the support plate 18, the rotating member 193, the fixing member 195, the elastic piece 197 and the washer 199 from being disengaged from the rotating shaft 191. The fixture 195 is not rotatable relative to the bracket 12. As shown in FIG. 4 , the notebook computer includes a body 20 , a cover 30 , and a hinge structure 10 connecting the body 20 and the cover 30 . The fixing portion 143 and the extension portion 145 of the base 14 are fixedly connected to the body 20 , and the support plate The lug 185 of the 18 is fixedly attached to the cover. In the state of Fig. 4, the cover 30 is rotated by a certain angle with respect to the body 20 about the first axis A1. Referring to FIG. 5, the cover 30 is rotated relative to the body 20 by a certain angle about the second axis A2. 12 200807220 When the cover body 30 is biased to rotate about the first axis A1, the bracket 12, the pivot shaft 16, the support plate 18 and the pivoting device are fixedly connected with the cover body 30 and the base 14 The body 20 rotates. During this process, the resilient washer 165 provides an axial force that creates a greater friction between the various components of the pivot assembly 16 and the base 14 and the bracket 12, allowing the cover to remain in any position. When the cover 30 is biased to rotate about the second axis A2, the rotating shaft 191, the rotating member 193 and the support plate 18 are both attached to the cover 3.
