Description

Rotating shaft structure Technical Field

[0001] This work relates to a hinge, particularly a hinge structure for a foldable electronic device. Prior Technology

[0002] Traditional folding electronic devices, such as laptop monitors and their bases, primarily use a single-axis hinge to connect the side of the monitor to the base, allowing the monitor to flip up or close relative to the base. However, beyond traditional laptops, and especially for existing dual-touchscreen computers, current design trends in folding devices mainly focus on improving upon the shortcomings of dual-touchscreen computers. The aim is to allow the two screens to come closer together during opening and closing, reducing the gap between them and preventing the internal structure of the hinge or pivot point from being exposed.

[0003] Existing flexible screen hinges and dual-hard screen hinges are mostly composed of fixed parts. For example, patent TWM648233U illustrates a flexible screen hinge structure where two first arc-shaped portions of a base are pivotally connected to two hinge modules. These two hinge modules are connected to a co-moving component and a torsion positioning component via at least one shaft. One end of a rotating component in any hinge module is connected to the first arc-shaped portion, and the middle section of the rotating component has at least one receiving groove to accommodate at least one cam component. One end of a door panel connecting rod is pivotally connected to one end of at least one cam component, and the other end of the at least one cam component is pivotally connected to the rotating component. One end of a housing connecting rod is pivotally connected to both the rotating component and the other end of the door panel connecting rod, and the other end of the housing connecting rod has a guide rail. One end of a co-moving component is connected to at least one shaft in a synchronously rotating manner, and the sliding portion of the other end of the co-moving component is connected to the guide rail for relative movement, thereby reducing the distance between the two screens and minimizing the protruding appearance. However, the connecting rods of the housing and the door panel, as well as the moving parts and the connecting rods of the housing, are pivotally connected and slide relative to each other by a straight rod. This structure requires a high degree of parallelism between the straight rod and the slide groove. If the gap between the two is too small or too large, it will affect the smoothness of the machine body rotation. Therefore, the tolerance control of the parts is more stringent in the manufacturing process, which leads to increased costs.

[0004] As shown in patent CN216772299U, a tilting hinge, folding machine housing and keyboard are provided. The torque assembly is made of stacked sheets and is mainly clamped in the base connecting the machine body through upper and lower clamping plates and fixed by partial welding. This combination method not only makes the yield unstable, but is also not conducive to assembly on flexible screen hinges and dual hard screen hinges with more complex structures. Summary of the Invention

[0005] In view of this, in order to provide a structure that is different from conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development, resulting in this creation.

[0006] One objective of this invention is to provide a pivot structure that addresses the high parallelism requirements of conventional pivot mechanisms between the straight rod and the slide groove. Excessive or insufficient clearance can affect the smoothness of the machine's rotation, leading to stricter tolerance control during manufacturing and increased costs. Furthermore, the structure using upper and lower clamping plates to hold the torque assembly results in unstable yield and is difficult to assemble. This invention addresses the issues of clearance and free travel in the connection between the straight rod and the slide groove in existing technologies by providing a plurality of first engaging slots on an adapter to stably engage and connect a plurality of first protrusions of a plurality of torque plates, and by connecting one end of the adapter to at least one moving component. This improves upon these problems and also allows for a wider tolerance range for the torque plates, enhancing assembly convenience and effectively increasing yield.

[0019] The rotating structure of this invention includes two rotating modules in opposite directions. One end of each rotating module is connected to at least one co-moving component and at least one torsional positioning component via at least one shaft, allowing the two rotating modules to rotate and open relative to each other.

[0020] Please refer to Figures 1 to 7, which are the first embodiment of the rotating shaft structure 1 of this invention. It mainly includes a first connecting rod 2, a second connecting rod 2', two bases (3,3'), two first rotating parts (4,4'), two second rotating parts (5,5'), two rotating modules (6,6'), two co-movement components (7,7'), and two torsion positioning components (8,8'). The first connecting rod 2 is a rectangular plate. The bottom end of the first connecting rod 2 is locked to a first housing 9. The top end of the first connecting rod 2 has a first groove 21. The inner walls of the two ends of the first groove 21 are respectively provided with an elongated straight groove, which serves as a first guide rail 22. The outer ends of the first groove 21 are respectively provided with a first notch 23. The inner wall of one of the first notches 23 is provided with an arc-shaped protrusion 24. The two arc-shaped protrusions 24 are respectively movably connected to two arc-shaped grooves 26 on the bottom surface of a first door panel 25, so that the first door panel 25 can rotate and shift relative to the first connecting rod 2 to support one half of the two halves of the flexible screen 91 upward. One side of the first connecting rod 2 has two first notches 27. The inner walls of the two ends of each first notch 27 are respectively provided with a pivot hole, which serves as a first pivot part 28.

[0021] The second connecting rod 2' has the same shape and structure as the first connecting rod 2. The second connecting rod 2' and the first connecting rod 2 are arranged in opposite directions, and their length directions are parallel to each other. The bottom end of the second housing connecting rod 2' is locked to a second housing 9'. The top end of the second housing connecting rod 2' has a second groove 21'.

The outer ends of the second groove 21' are respectively provided with a second notch 23'. The inner side wall of one of the second notches 23' is provided with an arc-shaped protrusion 24'. The two arc-shaped protrusions 24' are respectively movably connected to two arc-shaped grooves on the bottom surface of a second door panel 25', so that the second door panel 25' can rotate and shift relative to the second housing connecting rod 2' to support one half of the flexible screen 91. In addition, one side of the second housing connecting rod 2' has two second notches 26'. The inner side walls of the two ends of the two second notches 26' are respectively provided with a pivot hole, which serves as a second pivot part 27'.

[0022] Two bases (3,3') are respectively positioned at the two ends of the first connecting rod 2 and the second connecting rod 2' along the longitudinal direction. Taking one of the two bases (3,3') as an example, base 3 has a first side 31 and a second side 32 spaced apart and arranged side by side. Between the first side 31 and the second side 32, there is a first arc-shaped part 33 and a second arc-shaped part 34 in opposite directions. The first arc-shaped part 33 and the second arc-shaped part 34 each include a notch. Two parallel and spaced arc-shaped blocks are provided in any notch.

[0023] The two first rotating members (4, 4') have the same shape and structure. One end of the first rotating member 4 is provided with a first guide portion 41, which includes two spaced arc-shaped guide grooves. The two arc-shaped guide grooves are located on opposite sides of the first guide portion 41 and respectively connect with two arc-shaped blocks of the first arc-shaped portion 33, so that the first rotating member 4 can swing arc-shaped relative to the base 3. The other end of the first rotating member 4 has a first pivot hole 42 for a shaft to pass through, so that the first pivot portion 28 of the first connecting rod 2 can be pivotally connected to the other end of the first rotating member 4.

[0024] Two second rotating members (5, 5') and two first rotating members (4, 4') are arranged opposite to each other on both sides of two bases (3, 3'), and the two second rotating members (5, 5') and the two first rotating members (4, 4') have the same shape and structural configuration; one end of the second rotating member 5 has a second guide part 51, which is connected to the second arc-shaped part 34 of the base 3 in a relatively arc-shaped swinging manner; the other end of the second rotating member 5 has a second pivot hole 52 for a shaft to pass through, so that the second pivot part 27' of the second connecting rod 2' is pivotally connected to the other end of the second rotating member 5.

[0025] The two rotating modules (6,6') have the same shape and structure, and are arranged in opposite directions. The following description takes one of the two rotating modules (6,6') as an example. The rotating module 6 mainly includes a connector 61 and a plurality of torsion plates 62. The connector 61 is a flat plate. One end of the connector 61 has a lug 611 extending in opposite directions and a guide block 612 on both sides. The plate surface of the connector 61 has two hollowed-out receiving spaces 613. The other end of the connector 61 has a locking part 614. The locking part 614 is an elongated plate. The locking part 614 has a plurality of wedge-shaped grooves spaced apart along its length. The channel of any wedge-shaped groove gradually narrows inward from the other end of the connector 61 and connects to the receiving space 613. In practice, the wedge-shaped groove serves as the first locking groove 615.

[0026] A plurality of torsion plates 62 and a plurality of connecting plates 63 are stacked alternately. One end of the plurality of torsion plates 62 and one end of the plurality of connecting plates 63 are simultaneously pivotally connected to a first shaft 64. A second shaft 65 is simultaneously pivotally connected to one end of a plurality of torsion plates 62' and the other end of a plurality of connecting plates 63 of another rotating module 6'. A third shaft 66 and a fourth shaft 67 are respectively pivotally connected between the two ends of the plurality of connecting plates 63, so that the first shaft 64, the third shaft 66, the fourth shaft 67 and the second shaft 65 are parallel to each other and arranged in sequence with intervals. The other end of the plurality of torsion plates 62 has a plurality of wedge-shaped protrusions. Each wedge-shaped protrusion is formed by gradually shrinking outward from the other end of the torsion plate 62 and corresponds to the channel shape of the first snap-fit ​​groove 615, so that the plurality of wedge-shaped protrusions can be engaged and connected to the plurality of first snap-fit ​​grooves 615. In practice, the wedge-shaped protrusion serves as the first protrusion 621.

[0027] The two synchronously moving components (7, 7') have the same external shape and structure. The two synchronously moving components (7, 7') are parallel to each other and arranged side by side with intervals. The following description takes one of the two synchronously moving components (7, 7'), 7, as an example. The synchronously moving component 7 mainly includes a first synchronously moving member 71 and a second synchronously moving member 72. The first synchronously moving member 71 is an elongated connecting rod. One end of the first synchronously moving member 71 has a first meshing part 711, which is connected to the first shaft 64 in a synchronously rotating manner. The other end of the first synchronously moving member 71 has a first locking part 712, which has a third notch 713. The inner wall of the third notch 713 has a screw hole 714. One side of the other end of the first synchronously moving member 71 has a guide groove 715, and the other side of the other end of the first synchronously moving member 71 has an elongated straight block, which serves as a first sliding part 716.

[0028] The two first sliding parts (716, 716') are respectively confined within the two first guide rails 22 of the first housing connecting rod 2, allowing the two first sliding parts (716, 716') and the two first guide rails 22 of the first housing connecting rod 2 to move stably relative to each other. When the two guide blocks 612 of the adapter 61 slide into the guide grooves (715, 715') of the two first moving parts (71, 71'), the long direction of the guide grooves (715, 715') and the guide blocks 612 are parallel to the assembly direction. After the plurality of first protrusions 621 are correspondingly inserted into the plurality of first snap-fit ​​grooves 615, the two lugs 611 and the two screw holes (714, 714') are respectively locked with headed screws. Then the position of the adapter 61 can be flexibly and finely adjusted so that the plurality of first protrusions 621 can be stably engaged with the plurality of first snap-fit ​​grooves 615.

[0029] The second co-moving member 72 and the first co-moving member 71 have the same shape and structure, and the second co-moving member 72 and the first co-moving member 71 are arranged in opposite directions. One end of the second co-moving member 72 in the longitudinal direction has a second meshing part 721. The second meshing part 721 is connected to the second shaft 65 in a synchronous rotation manner. The second meshing part 721 is meshed with the first meshing part 711 of the first co-moving member 71 through an intermediate gear set 722, so that the first co-moving member 71 and the second co-moving member 72 rotate in opposite directions. Two gears of the intermediate gear set 722 pass through the third shaft 66 and the fourth shaft 67 respectively; the other end of the second co-moving member 72 in the longitudinal direction has a second locking part 723 and a second sliding part 724, which can also allow the plurality of first protrusions 621' of the other rotating module 6' to be stably engaged with the plurality of first locking grooves 615', and allow the two second sliding parts 724 to connect the two second guide rails 22' of the second housing connecting rod 2' in a relatively movable manner.

[0030] Furthermore, one end of the first shaft 64, the second shaft 65, the third shaft 66, and the fourth shaft 67 respectively passes through one of the two torsion positioning components (8, 8'), allowing the torsion positioning component 8 to be clamped and positioned between one of the two first rotating members (4, 4') and the co-moving component 7; the other end of the first shaft 64, the second shaft 65, the third shaft 66, and the fourth shaft 67 respectively passes through another torsion positioning component 8', allowing the torsion positioning component 8' to be positioned between another first rotating member 4' and another co-moving component 7', thereby compressing and positioning the two torsion positioning components (8, 8') respectively, so that the two halves of the relatively bent flexible screen 91 can rotate stably during the process of flipping to close or fully unfold, and can freely stop at a certain angle during rotation.

[0031] Please refer to Figures 8 and 9, which show the second embodiment of the rotating shaft structure 1 of this invention. The difference between this embodiment and the first embodiment is that: any one of the two rotating modules (6, 6') includes a connector 61' and a plurality of torque plates 62". The other end of any connector 61' has a second protrusion 611'. The second protrusion 611' is an elongated block. The top surface of the second protrusion 611' in the longitudinal direction is provided with a plurality of spaced upper protrusions and forms a plurality of spaced upper notches 612'. In implementation, the upper protrusions serve as the first limiting part 613'. The bottom surface of the second protrusion 611' in the longitudinal direction is provided with a plurality of spaced lower protrusions and forms a plurality of spaced lower notches 614'. In implementation, the lower protrusions serve as the second limiting part 615. Each of the plurality of torque plates 62” has an upper protrusion 621” and a lower protrusion 622” at its other end. A second engaging groove 623” is provided between the upper protrusion 621” and the lower protrusion 622”. In this way, the plurality of second engaging grooves 623” of the plurality of torque plates 62” can be engaged with the second protrusion 611’ of the adapter 61’, so that the plurality of upper protrusions 621” of the plurality of torque plates 62” are respectively limited between the plurality of first limiting portions 613’, and the plurality of lower protrusions 622” are respectively limited between the plurality of second limiting portions 615”, thereby forming a stable connection.

[0032] In summary, this invention not only facilitates assembly by setting a plurality of parallel wedge-shaped first engaging slots on the adapter and setting a wedge-shaped first protrusion on one end of a plurality of torque plates, allowing the plurality of first protrusions to enter each first engaging slot along a tapering channel, but also allows the plurality of first engaging slots to stably engage with the plurality of first protrusions of the plurality of torque plates, thereby improving the gap and free stroke problems caused by the connection between the straight rod and the sliding groove in the prior art; and by setting a counter-extending lug and guide block on both sides of one end of the adapter, and a first locking part and guide groove on one end of the first moving member, the position of the adapter can be moved and adjusted to allow the plurality of first protrusions to smoothly enter each first engaging slot, and then the lugs to lock onto one end face of the first moving member. In this way, the error value of the torque plates can be relaxed during manufacturing, thereby saving processing costs, improving the convenience of assembly, and effectively improving the yield of finished products.

Anyone skilled in the art should know that any easily conceivable variations or modifications are possible under the technical spirit of this invention and are covered by the patent application scope of this invention.
