The rotating shaft member 3 has a shaft body 31 that passes through the sliding seat 2 , and a connecting portion 32 that is provided on the shaft body 31 and used to be assembled to the cover 300 . When the rotating shaft member 3 is at the first angular position, the cover 300 is in a closed shape relative to the body 200 . When the rotating shaft member 3 is at the second angular position, the cover 300 is in a closed shape relative to the main body 200 . Open lid.

Referring to Figures 1, 3 and 5 to 7, the sliding seat 2 has a base body 23 with a substantially C-shaped structure, a plate body 24 assembled on the base body 23, and a combination of the base body 23 and the plate body. 24 collectively surround a defined accommodation space 25, the sleeve portion 21 is formed at the bottom of the base 23, and the sliding portion 22 is formed at the bottom of the plate body 24. It should be noted that in other embodiments, , the sliding seat 2 may not be a combination It is not a pre-installed structure but is constructed in one piece. The shaft body 31 of the rotating shaft member 3 has a linkage portion 311 located in the accommodating space 25 and a setting portion 312 passing through the sliding seat 2 . The linkage unit 4 includes a rack 41 disposed upward in the sliding groove 11 of the base 1 and extending along the front-rear direction D1, and a shaft 31 disposed on the rotating shaft member 3 in the accommodation space 25. The linkage part 311 is a driving gear 42 that can rotate with the rotating shaft member 3, and a driven gear 43 located in the accommodating space 25 and rotatably provided on the sliding seat 2. The driven gear 43 meshes with between the driving gear 42 and the rack 41 . Wherein, the driving gear 42 and the driven gear 43 are both spur gears.

Referring to FIGS. 7 to 9 , when the rotating shaft member 3 is at the first angular position, the cover 300 is closed relative to the body 200 , and the sliding seat 2 is at the first position; when the rotating shaft member 3 When rotating from the first angular position to the second angular position, the cover 300 is open relative to the main body 200 , and the linkage unit 4 slides the sliding seat 2 forward to the second position. As shown in FIG. 8 , during this process, the driving gear 42 rotates clockwise in the figure, and the driven gear 43 is linked to rotate counterclockwise in the figure to move forward on the rack 41 Rolling, thereby driving the sliding seat 2 and the rotating shaft member 3 to slide forward. That is to say, during the process of opening the cover 300, the cover 300 can slide forward in conjunction with the sliding seat 2 and the rotating shaft member 3. On the contrary, during the process of closing the cover 300, The cover 300 can slide backward in conjunction with the sliding seat 2 and the rotating shaft member 3 .

Referring to FIGS. 1 and 3 to 6 , the torsion unit 5 is provided on the rotating shaft member 3 and includes a stopper located at the proximal end of the setting portion 312 of the rotating shaft member 3 and rotating with the rotating shaft member 3 51, and a torsion module 52 provided on the setting portion 312 of the rotating shaft member 3 and sandwiched between the stopper 51 and the sliding seat 2 under pressure. The torque module 52 rotates with the setting portion 312 of the rotating shaft member 3 and is used to lean on the A positioning piece 521 against the sliding seat 2, a gasket piece 522 for leaning against the stopper 51 and rotating with the setting portion 312 of the rotating shaft member 3, and is clamped in the positioning position under pressure. A plurality of spring discs 523 between the member 521 and the gasket member 522. The elastic force provided by the spring disc 523 will increase the friction between the positioning member 521 and the sliding seat 2, thereby generating a positioning torque to resist the rotation of the rotating shaft member 3, so that the rotating shaft member 3 can rotate at Can be positioned steplessly during rotation.

In addition, the sliding seat 2 also has a first positioning structure 26 formed on the plate body 24 and facing the positioning member 521 of the torsion module 52 . The positioning member 521 has a first positioning structure 26 corresponding to the first positioning structure 26 . Two positioning structures 521a. When the rotating shaft member 3 is located at a specific angular position between the first angular position and the second angular position, the first positioning structure 26 and the second positioning structure 521a are concave-convexly matched with each other. The first positioning structure 26 has two positioning grooves 261, and the second positioning structure 521a has two positioning protrusions 521b. When the rotating shaft member 3 is located at the specific angular position, the positioning grooves 261 are in contact with the positioning bumps 521b. The bumps 521b are concave and convex with each other. It should be noted that in other embodiments, the first positioning structure 26 may also have the positioning protrusion 521b, and the second positioning structure 521a may have the positioning groove 261. In addition, the positioning protrusion 521a may have the positioning groove 261. The number of the block 521b and the positioning groove 261 may also be one or more than three.

In this embodiment, the specific angular position is the first angular position. Through the first positioning structure 26 and the second positioning structure 521a that are concave and convex with each other, the rotating shaft member 3 can be positioned at the first angular position. Additional positioning torque is obtained, thereby making the cover 300 less likely to be opened due to misoperation or other external forces when the cover is closed relative to the body 200, and the operating feel during the cover closing process can also be improved. It should be noted that in other implementations, the specific angular position may also be the second angular position or the other angular positions between the first angular position and the second angular position, and the number of the specific angular positions can also be more than two. At the practical application level, the number of the specific angular positions and their actual angles The position can be determined according to the position and number of the positioning protrusions 521b and the positioning grooves 261, and is therefore not limited to this embodiment.

It is worth mentioning that because the torque unit 5 used to provide positioning torque is only provided on the rotating shaft member 3 in a uniaxial arrangement, rather than being also provided on other components (such as the driven gear) at the same time. 43 above), so it is easier and more accurate to design or adjust the positioning torque.

To sum up, the present invention uses the sliding seat 2 of the rotating shaft member 3 that is slidably disposed on the base 1 and is rotatably penetrated, as well as the rack 41 and the driving gear of the linkage unit 4. 42 and the driven gear 43, when the rotating shaft member 3 rotates from the first angular position to the second angular position, the cover 300 provided on the rotating shaft member 3 can slide from the first position to the second angular position. The sliding base 2 in the second position slides along the front-to-back direction D1 (first direction). Therefore, the hinge 100 can meet the special design requirements of synchronous sliding when electronic products rotate.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by the patent of this invention.
