The chain of torque. [Prior Art] [0002] A general clamshell electronic device (such as a notebook computer, a mobile phone, etc.) is provided with a hinge device between the display of the electronic device and the keyboard to provide the torque required for the display to be opened relative to the keyboard. . [0003] The structure of the general hinge is shown in the patent cases of the Republic of China No. M386744, No. M381 989, No. M379970, and No. M378608. The common features of the hinge structures disclosed in the patents are that The utility model has a shaft center and two fixing seats mounted on the shaft center, wherein the two fixing seats are used for connecting two objects to be rotated and opened, such as a camping screen and a keyboard of the notebook computer, so that the screen can be rotated relative to the keyboard. Alternatively, the shaft of the hinge structure is additionally provided with two spacers having a concave-convex structure, a disk-shaped spacer, a friction pad, and the like, thereby providing a torsion force during rotation. [0004] However, the hinge structure of the above patents has a fixed torque at different opening or closing angles, so at the initial opening or closing, the user needs to increase the force of the force against the device, causing the initial opening or closing. The more laborious problem, and when the opening or closing is about to be completed, the direction of the user's force is the same as the gravity direction of the device, causing the device to speed up the opening or closing. A little accidental collision may occur. [New content] [0005] The main purpose of the present invention is to improve the above-mentioned defects, thereby resisting the device form number Λ0101, page 3/17 pages [0006] [0006] [0007] [0008] [0009] I099 year 12 Month's form a corresponding force at different opening or closing angles. In order to achieve the above object, the present invention proposes a chain of twisting force that varies with the opening angle. The money chain includes a shaft, a cam 2 that is fixed to the shaft, and a counter that is mounted on the hinge. Wherein, the shaft mandrel has a first fixing seat and a second fixing seat, so that the first fixing seat and the second fixing seat can have a rotation stroke relative to each other, and the cam piece is on the circumference. And a first-butting portion and a second abutting portion connecting the first abutting portion. The resisting member is normally pushed by an elastic body to resist the circumference of the cam piece and abuts in the rotating stroke The first abutting section of the cam piece and the second abutting section adjust the rotational torque. -''·X· As can be seen from the above, the new type can adjust the rotating torque through the elastic force of the elastic body when opening and closing, which not only achieves the labor-saving effect, but also increases the safety of use and avoids damage to the electronic device. And the cam piece is a single-piece structure. The specifications of the inner diameter and the length of the first abutting section and the second abutting section can be adjusted according to the requirements of the torsion force, so that the torque can be greatly changed. Meet the needs of a variety of electronic devices. - [Embodiment] β The detailed description and technical contents of this new model are described below with reference to the following figures: Please refer to "Figure 1 and Figure 2". This new type is a chain that changes the torque with the opening angle. The hinge 10 mainly includes a first fixing base 30 and a second fixing base which are disposed on the shaft center 20, and the first fixing base 30 is fixedly disposed on the center of the core. And the second fixing seat 4 is 活动 活动 活动 活动 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一The positive replacement page holder 30 and the second holder 4 can have two rotation strokes relative to each other; and the first holder 40 is provided with a stopper 4丨, and the shaft 2 is provided with a stopper 21, the stop block 41 and the stop piece 21 form a positioning relationship in the rotation stroke; and the shaft center 20 is sequentially provided with two torque pieces 22, 23, a cam piece 50, and a plurality of friction pads 25 And the disc-shaped spacer 24, and is locked at the end by a nut 26, wherein the two torsion pads 22, 23 have corresponding concave and convex structures, and The friction washers 25 and the disc spacers 24 together provide a torsion force during rotation; and the cam piece 5 is threaded and fixed to the shaft core 20, and a peripheral portion thereof is provided with a first abutting section and a connection. The first abutting section 52 of the first sin & 51, in the preferred embodiment of the present invention, the first abutting section 51 is a curved surface, and the second abutting section 52 is a plane, and the The second abutting section 52 is provided with a turning point 521 and the second abutting section 52 is divided into a front section 522 and a rear section 523. [0010] In addition, the hinge 10 is further provided with a resisting member 60 on the second fixing base 40. The resisting member 60 is provided with a resisting portion 61 on one side and a connecting portion 62 on the other side. The retaining member 60 is fixed to the second fixing base 40 by a fixing member 63, and a supporting block 64 is further disposed between the resisting member 6〇 and the second fixing base 40. The support block 64 is also fixed to the second fixing base 40 by the fixing member 63. The second fixing base 4 is provided with an accommodating space 42 for accommodating an elastic position at a position corresponding to the resisting member 60. The body 4 4 'such as a spring' is provided with a latch 4 3 for inserting and fixing the elastic body 44. The elastic body 44 is coupled to the connecting portion 62 of the resisting member 60 at one end, and normally pushes the resisting member 60 with its elastic force. The resisting member 60 abuts against the periphery of the cam piece 50 with its resisting portion 61 as it constitutes the main structure of the present invention. Form No. A0I01 Page 5 of 17 [0011] Month Z7 Day π See "Figure 3-1 to Figure 3-4", the new hinged tether can be applied to the electronic device that can be covered. Such as a notebook computer, a mobile phone, etc., and the first fixed seat 3 of the hinge 10 is connected to the electronic device clamshell display, and the second fixed seat 4 is connected to the button portion of the electronic device; When the button portion is engaged, the first fixing base 3 is closed to the second fixing base 40, and the resisting portion 61 of the resisting member 6 is pushed by the elastic body 44 to abut against the cam piece 5. The first abutting section 5 of the crucible is as shown in FIG. 3-1; if the first fixing seat 3 is opened by the force, the first fixing seat 30 can be opposite to the second fixing seat. 4 〇 generates a rotation stroke, at this time, the first fixing base 30 drives the shaft center 20, and the shaft core 2 〇 interlocks the cam piece 50 to rotate synchronously, so that the resisting portion 61 of the resisting member 6 脱离 is disengaged from the first Abutting the segment 51 and abutting the front portion 522 of the second abutting portion 52, thereby providing an auxiliary force for pushing the rotation of the shaft 20 to reduce the rotational torque. Resist the gravity of the display (not shown) mounted on the first mount 30. Since the direction of the assist force is the same as the direction in which the user applies the force, the user can achieve a labor-saving effect at the initial start (eg, Figure 3 _ 2). [0012] When the first fixing base 30 and the second fixing base 4 are relatively rotated to about 9 degrees, the resisting portion 61 of the resisting member 60 abuts against the turning point 521, and at this time, the rotating torque returns to normal. The state (as shown in FIG. 3-3); if the first fixing base 30 and the second fixing base 4 are continuously rotated relative to each other to more than 9 degrees, the resisting portion 61 of the resisting member 60 will be separated from the turning point 521. And abutting against the rear section 523 of the second abutting section 52, an assisting force is also provided to resist the gravity of the display (not shown), and the direction of the assisting force is opposite to the direction in which the user applies the force to open. In turn, the rotation torque is increased, and the required number of continuation is increased. Α0101 Page 6 of 17 December 27, 2008 The power of the child is replacing the page (as shown in Figure 3-4) ^ Therefore, at the beginning of the opening When the display on the first fixing base 30 is tilted forward, the elastic force of the elastic body 44 is used to assist the opening to achieve a labor-saving effect. After the opening to 90 degrees, the display on the first fixing base 30 is tilted back, and the elasticity is transmitted. The spring-assisted support of the body 44 prevents the display from falling over. [0013] In contrast, when the user wants to close the first fixing seat 30 from the position of FIG. 3-4 to the position of FIG. 3-1, since the resisting portion 61 of the resisting member 6 is received in FIG. The elastic body 44 is pushed, and the rear section 523' of the second abutting section 52 generates an auxiliary force against the gravity of the display. Since the assisting force is the same as the direction in which the biasing force is closed, the labor saving effect can be obtained at the initial stage of the closing. If it is closed to FIG. 3-2, the resisting portion 61 of the resisting member 60 abuts against the front portion 522 of the second abutting portion 52, and generates an assisting force against the gravity of the display 'because the assisting force is opposite to the direction in which the biasing force is closed. This causes the torsion of the rotation to increase, thus increasing the force required to continue to close. [0014] In summary, the present invention mainly pushes the resisting member 60 against the first abutting portion 51 or the first abutting portion #52 of the cam piece 5〇 during the rotation stroke through the elastic body 43. Resist the downward force of the first mount 3 (ie, gravity) to adjust the torsion during rotation; since the opening and closing are initial, the first mount 3 is lifted upward and elastic The elastic force of the body 43 reaches a labor-saving effect, and when the turning point 521 is opened or closed, the first fixing base 30 is pressed downward, and the force is added to resist the elastic force of the elastic body 43 to slow down or close. Speed, to avoid the user to open or close quickly, causing damage to the hinge or electronic device; therefore, the present invention not only achieves labor-saving effects, but also increases the safety of use of the electronic device.
