The present invention relates to an electronic device, and more particularly, to an electronic device including a hinge structure.

Generally speaking, a notebook computer is composed of a first body, a second body and a hinge structure, wherein the first body is capable of logic operation and data access, and the second body is capable of image display. The second body is connected to the first body through a hinge structure, so as to rotate and open and close relative to the first body within a specific angle range. In detail, the hinge structure can provide the torsion force required for the positioning of the second body, so as to stably maintain the opening and closing angle of the second body. After long-term use, the torsion force of the hinge structure will be attenuated due to wear and tear. In the case that it cannot be repaired and adjusted, most of the methods are to replace the new hinge structure.

In response to the specifications and sizes of different notebook computers, hinge manufacturers have to produce hinge structures of different specifications to match the notebook computer manufacturers, which in turn leads to problems such as increased manufacturing costs, difficulty in destocking, and complicated inventory management. That is to say, the hinge structure of a single specification cannot be universally used for several notebook computers of different specifications and sizes. On the other hand, the magnitude of the torque of the hinge structure has been set by the hinge manufacturer when it leaves the factory, and it is difficult to make fine adjustments in response to changes in product torque requirements or actual operating conditions of back-end users (such as operators of notebook computer manufacturers). Therefore, it lacks convenience and flexibility in operation.

The plurality of first torsion protrusions are in contact with the sleeve portion, and slide toward the second bracket portion with the adjustment sleeve, and the torsion conical portion is pushed by the adjustment sleeve and elastically deformed, and the plurality of second torsion protrusions move toward the second bracket. The sleeve portion moves so that at least a portion of the plurality of second torsion protrusions contacts the sleeve portion.

In an embodiment of the present invention, the outer diameter of the above-mentioned torsion ring portion remains unchanged in the direction from the first bracket portion to the second bracket portion.

Based on the above, in the electronic device of the present invention, the torsion force of the hinge structure can be finely adjusted according to product requirements or actual operating conditions, so it has excellent operational convenience and flexibility.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.

FIG. 1 is a partial schematic diagram of an internal structure of an electronic device according to an embodiment of the present invention. FIG. 2 is an exploded schematic diagram of a hinge structure according to an embodiment of the present invention. 3 is a schematic cross-sectional view of a hinge structure according to an embodiment of the present invention. In order to clearly present the configuration of the hinge structure 130 , the first body 110 and the second body 120 in FIG. 1 are shown with dotted lines. Please refer to FIG. 1 , in this embodiment, the electronic device 100 can be a notebook computer, and includes a first body 110 , a second body 120 and a hinge structure 130 , wherein the first body 110 has the capabilities of logic operation and data access. , and the second body 120 is capable of displaying images. The second body 120 is connected to the first body 110 through the hinge structure 130 , so as to be opened and closed relative to the first body 110 within a specific angle range.

As shown in FIGS. 1 to 3 , the hinge structure 130 includes a rotating shaft 131 , an adjusting sleeve 132 , a torsion sleeve 133 and a rotating sleeve 134 , wherein the rotating shaft 131 is fixed to the first body 110 , and the rotating sleeve 134 is fixed to the The second body 120 . Specifically, the adjusting sleeve 132 is sleeved on the rotating shaft 131 , the torque sleeve 133 is sleeved on the adjusting sleeve 132 , and the rotating sleeve 134 is sleeved on the torque sleeve 133 . That is, the torsion sleeve 133 is located between the rotation sleeve 134 and the adjustment sleeve 132 , wherein the torsion sleeve 133 contacts the inner wall surface of the rotation sleeve 134 , and the torsion sleeve 133 contacts the outer wall surface of the adjustment sleeve 132 .

As shown in FIG. 1 and FIG. 3 , the rotating shaft 131 is used as the rotation reference axis of the second body 120 . When the second body 120 rotates relative to the first body 110 around the rotating shaft 131 , the rotating sleeve 134 rotates synchronously with the second body 120 and The frictional resistance is generated with the torsion sleeve 133 to provide the torque required for the positioning of the second body 120 to stably maintain the opening and closing angle of the second body 120 .

FIG. 4 is a schematic cross-sectional view of the hinge structure of FIG. 3 after adjusting the torsion. As shown in FIG. 1 , FIG. 3 and FIG. 4 , the adjusting sleeve 132 can slide back and forth on the rotating shaft 131 . As the adjusting sleeve 132 slides on the rotating shaft 131 along the first direction D1 , the torque sleeve 133 is adjusted by the adjusting sleeve 132 . It is pushed and elastically deformed to expand toward the rotating sleeve 134 , thereby increasing the contact area or frictional resistance between the torque sleeve 133 and the rotating sleeve 134 . On the contrary, as the adjusting sleeve 132 slides on the rotating shaft 131 in the second direction D2 opposite to the first direction D1, the degree of pushing the torsion sleeve 133 by the adjusting sleeve 132 decreases and correspondingly produces elastic recovery, so as to Retracts toward the adjustment sleeve 132 , thereby reducing the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 .

In other words, the deformation amount of the torsion sleeve 133 is determined by the sliding amount of the adjustment sleeve 132 , and the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 is determined by the deformation amount of the torsion sleeve 133 decided.

As shown in FIG. 4 , when the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 increases, the user must exert a greater operating force to make the second body 120 relative to the first body 110 rotation, so it can give the user a clear operating feel. Alternatively, when the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 increases, the opening and closing angle of the second body 120 can be stably maintained to avoid accidents of the second body 120 Lifting or falling, etc.

Furthermore, the torsional force of the hinge structure 130 can be adjusted according to the user's needs or actual operating conditions, so it has excellent operational convenience and flexibility. On the other hand, since the torsion force of the hinge structure 130 can be adjusted, the hinge structure 130 of a single specification can not only be used in several notebook computers of different specifications and sizes, but also helps to reduce the manufacturing cost of the manufacturer, accelerate the destocking and Simplify inventory management.

As shown in FIGS. 1 to 3 , in this embodiment, the rotating shaft 131 includes a shaft portion 1311 , a first bracket portion 1312 and a second bracket portion 1313 opposite to the first bracket portion 1312 , wherein the shaft portion 1311 is located on the first bracket part 1312 and the second bracket part 1313 , and the first bracket part 1312 and the second bracket part 1313 are fixed to the first body 110 . During the rotation of the second body 120 relative to the first body 110 , the rotating sleeve 134 rotates synchronously with the second body 120 , and frictional resistance is generated between the torsion sleeve 133 and the rotating sleeve 134 . At the same time, the rotating shaft 131 will generate a resistance force opposite to the aforementioned frictional resistance.

Continuing from the above, since the opposite ends of the rotating shaft 131 (ie, the first support portion 1312 and the second support portion 1313 ) are both fixed to the first body 110 , the resistance force generated by the rotating shaft 131 can be equally distributed on the first body 110 , so that the rotating shaft 131 is less likely to be permanently deformed due to repeated stress, thereby improving the reliability and life of the hinge structure 130 .

As shown in FIGS. 2 to 4 , in this embodiment, the adjusting sleeve 132 is slidably sleeved on the shaft portion 1311 to slide along the first direction D1 or the second direction D2 opposite to the first direction D1 . For example, based on the contour matching between the adjusting sleeve 132 and the hole shaft of the shaft portion 1311 (the non-circular hole and the non-circular shaft as shown in FIG. 2 ), the adjusting sleeve 132 can slide on the shaft portion 1311 , but It cannot rotate around the shaft portion 1311 .

As shown in FIG. 1 to FIG. 3 , the rotating sleeve 134 includes a sleeve part 1341 and a third bracket part 1342 connecting the sleeve part 1341 , wherein the sleeve part 1341 is sleeved on the torque sleeve 133 , and the third bracket part 1342 It is fixed on the second body 120 . Specifically, the torsion sleeve 133 is located between the sleeve part 1341 and the adjustment sleeve 132 , wherein the torsion sleeve 133 contacts the inner wall surface of the sleeve part 1341 , and the torsion sleeve 133 contacts the outer wall surface of the adjustment sleeve 132 .

As shown in FIGS. 3 and 4 , as the adjusting sleeve 132 slides toward the second bracket portion 1313 along the first direction D1 , the torsion sleeve 133 is pushed by the adjusting sleeve 132 and elastically deformed to enlarge the sleeve portion. The contact area or frictional resistance between 1341 and the torsion sleeve 133.

As shown in FIGS. 2 to 4 , in this embodiment, the hinge structure 130 further includes a nut 135 screwed to the shaft portion 1311 , wherein the nut 135 is located between the first bracket portion 1312 and the adjusting sleeve 132 , and The nut 135 contacts one end of the adjusting sleeve 132 facing the first bracket portion 1312 . Therefore, when the nut 135 is rotated and slides toward the second bracket portion 1313 along the first direction D1, the adjusting sleeve 132 is pushed by the nut 135, so that the torsion sleeve 133 is pushed by the adjusting sleeve 132 and elastically deformed , so as to increase the contact area or frictional resistance between the sleeve portion 1341 and the torsion sleeve 133 . Conversely, when the nut 135 is rotated and slides toward the first bracket portion 1312 along the second direction D2, the elastically restored torsion sleeve 133 pushes the adjustment sleeve 132 to slide toward the first bracket portion 1312 along the second direction D2. At the same time, the torsion sleeve 133 retreats toward the adjustment sleeve 132 , thereby reducing the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 .

In other words, the user can flexibly adjust the torsion force of the hinge structure 130 by rotating the nut 135 forward or reverse, so the operation is extremely simple and intuitive.

On the other hand, when the nut 135 is rotated and slid toward the second bracket portion 1313 along the first direction D1, the adjustment sleeve 132 is pushed toward the second bracket portion 1313 by the nut 135, so as to reduce the size of the adjustment sleeve 132 and the second bracket portion 1313. The distance between the two bracket parts 1313 . On the contrary, when the nut 135 is rotated and slid toward the first bracket portion 1312 along the second direction D2, the adjusting sleeve 132 is pushed toward the first bracket portion 1312 by the elastically restored torsion sleeve 133 to enlarge the adjusting sleeve The distance between the barrel 132 and the second bracket portion 1313 .

As shown in FIGS. 3 and 4 , the shaft portion 1311 has a thread 1314 , and the nut 135 is screwed to the thread 1314 . A portion of the thread 1314 is covered by the nut 135 and another portion of the thread 1314 is covered by the adjustment sleeve 132 . As the nut 135 pushes the adjusting sleeve 132 to slide toward the second bracket portion 1313 along the first direction D1, the range of the thread 1314 covered by the adjusting sleeve 132 gradually decreases. In addition, as the nut 135 slides toward the second bracket portion 1313 along the first direction D1, the thread 1314 is gradually exposed to the outside. The more turns of the threads 1314 are exposed, the greater the contact area or frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 , which can be used as a reference for users to make precise adjustments.

On the other hand, since the nut 135 contacts the end of the adjusting sleeve 132 facing the first bracket portion 1312, and the nut 135 is screwed to the thread 1314, the distance S1 between the thread 1314 and the first bracket portion 1312 is smaller than that of the thread The distance S2 between 1314 and the second bracket portion 1313 is shown in FIG. 2 and FIG. 3 .

As shown in FIGS. 3 and 4 , the rotating shaft 131 further includes a positioning portion 1315 located between the shaft portion 1311 and the second bracket portion 1313 , and the torsion sleeve 133 abuts against the positioning portion 1315 . Therefore, when the adjusting sleeve 132 is pushed by the torsion sleeve 133 , the positioning portion 1315 can block the torsion sleeve 133 to prevent the adjusting sleeve 132 from pushing the torsion sleeve 133 toward the second bracket portion 1313 . In addition, since the torsion sleeve 133 is positioned between the adjustment sleeve 132 and the positioning portion 1315 , the torsion sleeve 133 does not arbitrarily slide on the shaft portion 1311 .

As shown in FIGS. 2 to 4 , in this embodiment, the adjustment sleeve 132 includes an adjustment tapered portion 1321 , and correspondingly, the torsion sleeve 133 includes a torsion tapered portion 1331 sleeved on the adjustment tapered portion 1321 . Specifically, the outer diameter OD1 of the adjustment tapered portion 1321 and the outer diameter OD2 of the torsion tapered portion 1331 gradually decrease from the first bracket portion 1312 to the second bracket portion 1313 (ie, the first direction D1 ), and the outer diameter OD2 is greater than the outer diameter OD1. Based on the cooperation between the outer contour of the adjustment cone 1321 and the inner contour of the torsion cone 1331 , the adjustment cone 1321 sliding along the first direction D1 can push the torsion cone 1331 to make the torsion cone 1331 outward Expansion (ie, elastic deformation). On the contrary, the inwardly retracted (ie elastically restored) torsion tapered portion 1331 can push the adjustment tapered portion 1321 to slide along the second direction D2.

On the other hand, the torsion sleeve 133 has a bottom end 1332 toward the first bracket portion 1312 and two slits 1333 extending from the bottom end 1332 to the second bracket portion 1313 . Further, the two slits 1333 are symmetrically arranged, and divide the torsion sleeve 133 (or the torsion cone 1331 ) into two torsion halves 133a. As the adjusting sleeve 132 slides toward the second bracket portion 1313 , the two torque halves 133 a are pushed by the adjusting sleeve 132 and expand or move toward the sleeve portion 1341 . Furthermore, the two slits 1333 serve as the structural weakness of the torsion sleeve 133 (or the torsion taper portion 1331 ), so that the torsion sleeve 133 (or the torsion taper portion 1331 ) can be affected by the adjustment sleeve 132 . elastic deformation caused by pushing.

As shown in FIG. 2 , the extending direction of the two slits 1333 is parallel to the extending direction of the shaft portion 1311 , and the torsion sleeve 133 (or the torsion taper portion 1331 ) is divided into two symmetrical torsion halves 133 a , In order to improve the consistency and symmetry of the contact area between the two torsion halves 133a and the sleeve portion 1341 .

As shown in FIGS. 2 to 4 , in this embodiment, the torsion sleeve 133 includes a torsion ring portion 1334 connected to the torsion tapered portion 1331 and sleeved on the adjustment sleeve 132 , and a plurality of torsion ring portions 1334 protruding from the torsion ring portion 1334 . The first torsion convex portion 1335 and a plurality of second torsion convex portions 1336 protruding from the torsion tapered portion 1331 . In detail, the torsion tapered portion 1331 is located between the torsion annular portion 1334 and the second bracket portion 1313 , wherein the maximum outer diameter of the torsion sleeve 133 falls on the torsion annular portion 1334 , and the outer diameter OD3 of the torsion annular portion 1334 is from The direction from the first bracket portion 1312 to the second bracket portion 1313 (ie, the first direction D1 ) remains unchanged.

As shown in FIG. 3 , the plurality of first torsion convex portions 1335 contact the sleeve portion 1341 , so that a first frictional resistance is generated between the torsion ring portion 1334 and the rotating sleeve 134 . As shown in FIG. 4 , as the adjusting sleeve 132 slides toward the second bracket portion 1313 , the torsional conical portion 1331 is pushed by the adjusting sleeve 132 and elastically deforms. When the torsion tapered portion 1331 expands or moves toward the sleeve portion 1341 , the plurality of second torsion convex portions 1336 move toward the sleeve portion 1341 , and at least part of the plurality of second torsion convex portions 1336 contacts the sleeve portion 1341 , so that a second frictional resistance is generated between the torsion tapered portion 1331 and the rotating sleeve 134 .

Further, the first frictional resistance is used as the basic frictional resistance between the torsion sleeve 133 and the rotating sleeve 134 . The frictional resistance with the rotating sleeve 134 gradually increases. Furthermore, the rotating sleeve 134 may be made of a wear-resistant material, such as polyoxymethylene (POM) or polycarbonate (PC).
