New description: [New technical field] This creation is about a kind of pivot structure', especially about a kind of I axis positioning function and multi-section torque. [Prior Art] Generally, the clamshell device, such as a notebook computer, a clamshell type mobile phone, and a translation machine, is provided with a pivot structure to provide a function of opening the lid and the base of the clamshell device. Referring to FIG. 1, the notebook computer 1 has a top cover 10, a base u and two 12s. The pivot structure 12 has a first fixing member | a second fixing member 122' and the two fixing members are respectively fixed to the pens LH, 10 and the base 11. Thereby, the upper cover 10 is operated by the & pivot 3. j Opening and closing Because the application of the lidping device is becoming more and more common, it is demanding, for example, the need to use and use the multi-segment torque requirement during the opening process. The trick is how to put the pivot into the j-point, so that it not only has the function of rotation, but also the need to improve the requirements, which is necessary for the current technology. "His Functionality [New Content] One of the purposes of this creation is to provide a pivotal anchoring structure - the outer arm of the axle and the bushing of the bearing plate! The bar is between the carrying plate and the bushing During the rotation, 'Make it possible to be positioned by the active M331055. Another object of the present invention is to provide a multi-segment twist structure, in which a shaft member is supported by a pivot member, a shaft rod and a cymbal shape design, so that the shaft rod is in the carrier plate member and the sleeve The pivot structure can provide multiple stages of torque. This process provides a multi-segment torque pivoting shaft structure including - the parent shaft, the - carrying plate and the - male shaft. The female H-axis cylinder has a carrier plate member disposed in the shaft cylinder, and the carrier plate member has a top portion and two elastic portions respectively connected to the two sides of the top portion. The male shaft has two axes and the shaft is rotatably coupled to the top and bottom of the carrier plate member - wherein the periphery of the radial section of the shaft has a circular arc portion and a full position portion. The positioning section has at least a straight edge, and the straight: end abuts the circular arc section. When the shaft is rotated at the top of the shaft cylinder and the carrier plate member so that the top of the carrier plate member is in contact with the arc segment, the structure can provide a first torque. When the shaft rotates between the shaft barrel and the top of the carrier plate, so that the top of the carrier plate member is in contact with the straight edge, the shaft structure can provide a second torsion force greater than the first torsion force, so that the shaft rod is not easily rotated to the arc segment The male shaft is positioned in contact with the top of the carrier member. The present invention further provides a multi-segment torque pivot structure comprising a female shaft, a carrier plate member and a male shaft. The female shaft has a shaft cylinder, and the supporting plate member is disposed in the shaft cylinder, and the supporting plate member has a top portion and two elastic portions respectively connected to the two sides of the top portion. The male shaft has a shaft and the shaft is rotatably coupled to the top of the carrier plate and the inner edge of the shaft. Wherein, the circumference of the radial section of the shaft includes a first circular arc section and a second circular arc section, and the first circular arc zone has a first circular arc radius of 6 M331055. In addition, the female shaft 21 is further smashed. ^, the shaft is called the end, or the two is included in the mosquito part 212, which is connected to the formation. The male shaft 23 further includes a side extension end of the 4-axis barrel 211. The above-mentioned ninth-amp;=^-connected=rod can be selectively fixed to one 掀Tfj2, f, respectively, and the member 232 is opened and closed. For the shaft ~ relative to the base to reach the shaft; 31 outside the 3 out of the bearing plate 22 and the figure to explain. Referring to the cross-sectional view of Fig. AH231, the first embodiment of the pivot structure is abbreviated: the peripheral section of the radial section of the creative rod 231 is continued. As shown, the shaft positioning section is fixed to the gas-arc section 2312 and - 2314a, and the straight side 2314a and the second side 314 have at least two ends of the straight edge. The two turns are adjacent to the arc segment 2312, respectively. As shown in FIG. 4A, when the shaft 231 rotates between the tops 221 of the jaws 22, the top 211 and the top plate 221 of the carrier plate member 22 are far arc regions 2312 In contact with the bearing force, when the shaft 231 is provided with a 221th rotation in the barrel 2n, the yoke and the top 221 of the carrier plate 22 are turned "to make the straight edge 2314a contact the carrier plate 2 221". The 'pivot structure 20 provides a greater than force' to position the shaft 231. In the first embodiment, the top portion 221 of the carrier plate member 22 is an arc-shaped structure which is substantially compatible with the contour of the circle & area I 2312 of the shaft 231. This can make the shaft 231 smoother. % Refer to Figure 5A to Figure 5B, which is a schematic view of the rotation of the second embodiment of the present invention. The difference between the second embodiment and the first embodiment 8 M331055 is that in the other pivot structure 2〇a, the clamping section 2314 of the other shaft 231a further includes a hypotenuse 2314b, and the hypotenuse=14b The end is connected to the straight side 23l4a, and the other end is connected to the arc section 2312. That is, the 'arc section 2312, the straight side and the oblique side 2314b sequentially form the radial periphery of the shaft 23u. During the counterclockwise rotation of the shaft 231a, the top 221 of the carrier plate member 22 sequentially contacts the arcuate section 2312 and the straight edge until the beveled edge 2314b abuts the carrier plate member 22. At this time, the beveled edge 231 easily passes over the carrier plate member 22' to thereby restrain the shaft 23U, so that the shaft 23la is not easily rotated in the counterclockwise direction, thereby providing a better positioning function. # Τ ί Figure 8A to Figure 6B are schematic views of the rotation of the second embodiment of the present pivot structure. Since in the foregoing embodiment, the intersection of the =section 2312 and the positioning section 2314 is a corner of the circular disk substantially forming a protrusion. In the case of ^^, the intersection angle is often rubbed against the carrier plate member 22, and the money is smoothed, and the wear of the shaft 231a is eliminated. In the second embodiment, the other pivot structure 2〇b has 231b 'The straight edge 2314a of the rod 231b and the circle of the circular orphan section 2312 have a groove 2316, and the groove 2316 is a groove 拠' for accommodating a _24. Therefore, 24' can make the arc segment 2312 and the positioning segment 23 ^ have another axis in the axis structure 20c, the shaft 23u ^ 2 9 M331055 edge package, a first round fox segment 2312 and - Two arc regions and one of the arc segments 2312 - arc half (four) " one of the first arc segments 2317 second arc radius! ·2. I: the two ends of the first arc segment 2312 are respectively adjacent to the second arc region; the ends of the π-free portion are adjacent to each other, and the adjacent ends are connected by a hypotenuse. In this embodiment, when the shaft 231c is in the middle of the shaft cylinder 2u, the top of the wire carrier member 22, 221 is abutting against g: two f ^ 2312, the shaft needs to be rotated by a first torque. 231c, that is, the pivot structure 20c can provide the first torque. If the carrier plate 22 221 abuts the second arc segment 2317, the shaft 231c is only required to be rotated by a second torque less than ^1. That is, the pivot structure can provide a second torque smaller than the first torsion. In other words, in the embodiment, the pivot structure 20c can provide two-stage torque. FIG. 8A to FIG. The shaft structure, the rotation diagram of the fifth embodiment. The difference between the fifth embodiment and the fourth embodiment is that the other pivot structure 2〇d has a shaft 231d. The circumference of the radial section of the shaft 231d further includes a third & J section 2318: | The third arc radius Γ3 of one of the third arc segments 2318 is smaller than the second arc radius r2 of the second arc segment 2317. When the shaft 231d is inside the barrel 211 During the rotation, when the top portion 221 of the plate member 22 abuts against the third circular arc portion 2318, the third torque is smaller than the second torsion force of the second torsion force. Axis = 31d: that is, the pivot structure 2〇d can further provide a third torque smaller than the second twist. In other words, in the present embodiment, the pivot joint 20d can provide three-stage torque. The pivot structure designed by the creative concept of Figure 7A, Figure 7b, Figure 8A and Figure 8B can have multiple sections of torsion rotation during the rotation process. Please refer to Figure 9 for the creation of the pivot structure. The shaft tube and the bearing plate are integrally formed. The figure is M331055. The other structure 〇e has the plate member 22a and the above-mentioned shaft 23lb /mu mesh, and the pivotal structure is two; One of the examples of the number of components can be reduced: the value of the two is considered to be that the actual forming concept can be applied to any of the above embodiments. In summary, the pivot of the present invention has the following advantages: The structure of the bearing plate and the shape of the shaft of the shaft can be set to have a positioning function during the rotation. The bearing plate and the shape of the shaft of the two-axis structure are set to "lift the shaft: many segments are twisted Third, the use of a small number of components with simple construction, assembled and have the function and different The pivotal structure of the rotational section of the torsion. When the pivot of the creation is applied to the clamshell device, it can be used with the positioning area required for the capping device, or the required multi-section torque rotation interval, and the structure of the shaft. For example, the best positioning when the notebook is turned on, the positioning area when the notebook is opened, the torsion rotation area that needs to be turned on during the opening or closing process, and the like. Although the present invention has been described above by way of a preferred example, it is not intended to limit the spirit of the creation and the creative entity only to the above embodiments. For those skilled in the art, it is easy to understand and utilize other components or methods to produce the same effect. Therefore, modifications made within the scope of the spirit of this creation should be included in the following patent application.
