M444023 V. New description: [New technical field] [0001] This case relates to a hinge, especially a ball-type device with two cam structures, and the two cam structures respectively provide automatic locking and increased friction torque . [Prior Art] [0002] According to electronic products, such as portable computers, electronic dictionaries, portable audio and video playback devices, and clamshell mobile phones, the main body is placed in the lower half, and the hinge and the upper half are used. The cover body is coupled so that the cover body can be opened and closed with respect to the body portion. Therefore, the hub is also a major factor in determining the quality of these products. [0003]

However, it is inconvenient to avoid the provision of a sliding switch or a push switch at the open end of the electronic product and the open end of the cover. Therefore, as in the case of the domestic patent publication No. M296586 of the applicant of the present application, the "rotating shaft structure with automatic locking" (corresponding to the Chinese Patent No. 20062000 1 995. 4 and the US Patent No. 7, 603, 747) As shown in the figure, it is combined with a cam structure on the hinge, the cam structure is formed by a latching fixing member and a latching rotating member, so that the hinge has an automatic closing effect. [0004] With the advancement of touch technology, the use of touch screens for portable computers has become an inevitable trend. When the touch screen of the portable computer is opened to an operable state, only the aforementioned cam structure is provided. The effect of automatic locking without adding additional frictional torque changes, such as increasing the frictional torque within a certain range of angles, so that when the user presses or slides the touch screen with a finger, the touch screen is biased and Turning it backwards and tilting, which causes inconvenience in touch operation, and seriously affects the touch and the smoothness of the 10121687# single number deletion 1 page 3 / 37 page 1012054758-0 M444023.

The arrangement of the second inner and outer grooves 513, 514 and the second inner and outer projections 522, 523 of the second fixing member 52 provides an auxiliary automatic locking function of the first cam structure 4. In particular, the second inner and outer grooves 513 and 514 of the second rotating member 51 of the second cam structure 5 are climbed out by the second inner and outer protrusions 522 and 523 of the second fixing member 52. Then, the third inner and outer bumps 515 and 51 6 are further climbed to the second inner and outer bumps 522 and 523, thereby increasing the distance between the second fixing member 52 and the second rotating member 51, so that the distance The second fixing member 52 laterally presses the elastic body 6, thereby increasing the frictional torque of the hinge. [0040]

The elastic body 6 is sleeved on both sides of the pivot shaft 1 to axially move the first and second fixing members 42 and 52 on the pivot shaft 1. When the elastic body 6 is implemented, as shown in the figure, a disc-shaped elastic piece is used, but not limited thereto, and it is also a corrugated spring or a spring. [0041] The pressing member 7 is coupled to the engaging portion 12 on both sides of the pivot 1 for specifying the front members so that the members are not disengaged by the pivot 1. Among them, it is preferable to prevent the nut from being removed when the pressing member 7 is implemented. [0042] When assembling the case, the first shaft 1 is sleeved in the sleeve hole 211 of the first bracket 2, and the first rotating member of the first bracket 3 and the first cam structure 4 is traversed on the side of the pivot shaft 1 41 and the first fixing member 42, the elastic body 6 and the spacer 7, and combining the first free end of the pivot 1 with the pressing member 7; and 1〇1216^单织Α0ΗΠ第10页/ Total 37 pages 1012054758-0 M444023 The other side of the pivot 1 passes through the second rotating member 51 of the second cam structure 5 and the second fixing member 52, the elastic body 6 and the spacer 7, and the pivot is The joint portion 12 of the free end is combined with the pressing member 7, that is, the assembly of the hinge is completed, and the assembled perspective view and the plan view of the button are as shown in FIG. 5 and FIG. The first inner and outer protrusions 422 and 423 of the first fixing member 42 and the second inner and outer protrusions 522 and 523 of the second fixing member 52 are respectively engaged with the first inner and outer parts of the first rotating member 41. The grooves 413, 414 and the second inner and outer grooves 513, 514 of the second rotating member 51 are in a locked state. [〇〇44] When the touch screen of the portable computer is opened backward, the shaft hole 311 of the third bracket 3 rotates around the pivot shaft 1, so that the third bracket 3 synchronously drives the first and second rotating members 41, 51 rotation; and the pivot 1, the first and second fixing members 42, 52, the elastic body 6 and the spacer 8 are in a fixed state. "At this time, the first and second rotating members 41, 51 are first and second. The two inner and outer grooves 413, 414, 513, and 514 are respectively climbed out of the first and second fixing members 42, 52, and the first and second inner and outer protrusions 422, 423, 522, and 523, so that the The first and second inner and outer bumps 422, 423, 522, and 523 abut each other on the contact faces 412 and 512 of the first and second rotating members 41 and 51 as shown in FIG. The two fixing members 42 and 52 axially move and respectively compress the elastic body 6 on the same side. At this time, the touch screen can generate a stagnant positioning effect by the frictional torque of the hinge. [0045] when the touch screen continues to be opened back to about 90 degrees, the first and second inner and outer bumps 422, 423 are still moved on the contact surface 412 of the first rotating member 41; and the second rotation The third inner and outer bumps 515, 1012054758-0 10121687# early number A0101, the first slanting surface of the M444023 516 are respectively climbed into the second inner and outer parts of the second fixing member 52. The end portions of the bumps 522 and 523 are inclined. Then, as shown in FIG. 8, the touch screen is further opened back to about 100 degrees, so that the third inner 'outer bumps 515, 516 of the second rotating member 51 are overlapped with the second fixing member 52. Two inner and outer bumps 522, 523; at this time, the distance between the second rotating member 51 and the second fixing member 52 is increased, so that the second fixing member 52 continuously presses the adjacent elastic body 6 laterally, The amount of compression of the elastic body 6 is increased, and the second rotating member 51 and the fixing piece 21 of the second bracket 2 are axially applied, thereby increasing the frictional torque of the hinge. In practice, the opening angle is not limited to the foregoing embodiment, and the difference is different depending on different requirements. [0046]

When the touch screen is forwardly closed, the third bracket 3 and the first and second rotating members 41 ′ 51 are reversed. At this time, the contact surface 412 of the first rotating member 41 is along the first fixing member 42 . The first inner and outer bumps 422, 423 are reversed so that the elastic body 6 on the same side does not have any elastic change; and the third inner and outer bumps 515, 516 of the second rotating member 51 are along the second fixed After the second inner and outer bumps 522 and 523 of the member 52 are reversed and detached, the contact surface 512 of the second rotating member 51 abuts against the second inner and outer bumps 522 and 523 to elasticize the same side. The body 6 bounces slightly, and the torque of the hinge is reduced. Then, the touch screen continues to be forwardly closed, so that the first and second inner 'outer grooves 413, 414, 513, 514 of the first and second rotating members 41, 51 are respectively moved to the first and second When the first and second inner and outer bumps 422, 423, 522, and 523 of the fixing members 42 and 52 are spring-backed by the elastic members 6 on both sides, the first and second inner and outer grooves 413 and 414 are 513, 514 automatically buckles into the first and second inner and outer bumps 422, 423, 522, and 523 to form an automatic latching state of the pole. 10121687^^ A〇101 Page 12 of 37 1012054758-0 [0047] M444023

In particular, the first and second rotating members 41, 51 and the recesses and projections provided by the first and second fixing members 42, 52 are interchangeable with each other, that is, the first inner and outer grooves 413, 414 and the first inner portion. , the outer bumps are similar to each other, and the second inner and outer grooves 513, 514 'the third inner and outer bumps = ', 516 and the second inner and outer & block 522, if they are interchangeable with each other The first rotating member 4 is provided with first inner and outer convex portions, the first fixed member 42 is provided with first inner and outer concave grooves, and the first rotating member 51 is provided with first inner and outer convex blocks The two fixing members 52 are provided with second inner and outer grooves and second inner and outer convex blocks, which are also the areas to be protected by the hinge. FIG. 9 is an exploded perspective view of the second embodiment of the second cam structure of the present invention. The difference between the second embodiment and the second cam structure is that the second rotating member 51 of the second cam structure 5 is not provided. There are second inner and outer grooves, but within a predetermined angle range on the contact surface 512, for example, 9 〇 to 21 各自 degrees, respectively, the third inner and outer bumps 515, 516. Therefore, when the ejector is in the closed state, the second inner and outer protrusions (10) and 523 of the second fixing member 52 abut against the contact surface 512 of the second rotating member 51, so that the second cam structure 5 does not The function of automatic locking is further provided, and only within the preset angle range, it is known that 90 to 210 degrees increase the friction torque of the second cam structure 5. As shown in FIG. 10 to FIG. 12, it is a perspective view of a second embodiment of the hinge of the present invention and a perspective view of the assembled body, wherein the same components as the above-mentioned embodiment are followed by the same component name and figure number. The difference between the example and the foregoing first embodiment is that the side of the movable frame 31 of the third bracket 3 is coupled, for example, adjacent to the second second cam structure 5, for example, riveted to an auxiliary frame 33, which is adjacent to the shaft. The hole 311 is provided with a circular pivot hole 331 for the pivot 1 to pass through.

Of course, the first and second protrusions 411 and 511 can be respectively inserted into the auxiliary frame piece 33 and the movable frame piece 31 by changing the auxiliary frame piece 33 to be mounted on the side surface of the movable frame piece 31. The category that the hub wants to protect. [0050] As shown in FIG. 13 and FIG. 14, the perspective view of the third embodiment of the present invention and the assembled perspective view are for increasing the scope of application to meet the internal space setting of different electronic products, wherein The same members of the foregoing first embodiment all use the same component name and figure number. The difference between this embodiment and the foregoing first embodiment is that different stereoscopic states are exhibited by changing the positions of the first and second brackets 2'3. As shown in FIG. 13, the fixing bracket 21 of the first bracket 2 of the embodiment is pivoted between the elastic body 6 and the pressing member 7, without the arrangement of the spacer, and the friction torque is increased, and the first cam is added. A friction plate 9 interlocking with the pivot shaft 1 is added between the first rotating member 41 of the structure 4 and the movable piece 31 of the second bracket 3. [0051]
