Description

Technical Field

[0001] This utility model relates to a hinge, and more particularly to a hinge that can be applied to electronic devices such as laptops. Background Technology

[0002] Users often need to use cooling stands to elevate the back of their laptops when using electronic devices such as laptops, in order to increase the laptop's cooling space and improve keyboard comfort. However, these stand-ups are not very convenient to store or use, and their stability during use could be improved. Therefore, finding a convenient and stable way to elevate the back of a laptop while using it is an important issue. Utility Model Content

[0003] One object of this invention is to provide a shaft that can improve at least one problem in the prior art.

[0004] In some embodiments, the rotating shaft of this utility model includes a base, a rotating unit, a translational slider, and a rotating foot pad. The rotating unit includes a rotating member and a first connecting protrusion. The rotating member is disposed on the base and can rotate relative to the base between a first position and a second position about a first rotation axis parallel to the left-right direction. The first connecting protrusion is linked to the rotating member and can rotate relative to the base about a second rotation axis parallel to the left-right direction. The translational slider is disposed on the base and can slide relative to the base between a third position and a fourth position in the front-back direction. The translational slider has a first concave rail and a second concave rail formed recessed along the left-right direction. The first connecting protrusion of the rotating unit is slidably disposed within the first concave rail, and the second concave rail extends in the vertical direction. The rotating foot pad is pivotally mounted on the base and can rotate relative to the base about a third rotation axis parallel to the left-right direction between a folded position and an upright position. The rotating foot pad has a second connecting protrusion located at one end and slidably disposed within the second concave rail, a foot pad body located at the other end, and a pivot portion located between the second connecting protrusion and the foot pad body and pivotally connected to the base. When the rotating member is in the first position, the translational slider is in the third position, and the rotating foot pad is in the folded position, the foot pad body of the rotating foot pad is relatively close to the base; when the rotating member rotates to the second position, the first connecting protrusion drives the translational slider to slide along the front-back direction to the fourth position, thereby driving the rotating foot pad to rotate to the upright position, where the foot pad body of the rotating foot pad is relatively away from the base.

[0005] In some embodiments, the rotating member passes through a transition position during its rotation relative to the base between the first and second positions. The first concave rail has a connected drive rail and an arc-shaped rail, the radius of curvature of which is equal to the distance between the first connecting protrusion and the second rotation axis. When the rotating member is in the first position, the translational slider is in the third position, and the rotating foot pad is in the retracted position. When the rotating member rotates from the first position to the transition position, the first connecting protrusion slides toward the drive rail and returns to the junction of the drive rail and the arc-shaped rail, thereby driving the translational slider to slide along the front-back direction to the fourth position, so as to drive the rotating foot pad to rotate to the supported position. When the rotating member rotates from the transition position to the second position, the first connecting protrusion slides along the arc-shaped rail, the translational slider does not slide, and the rotating foot pad does not rotate.

[0006] In some embodiments, the drive rail is straight and tangent to the arc-shaped rail.

[0007] In some embodiments, the base has a plurality of guide grooves recessed in the left-right direction and extending in the front-back direction, and the translational slider has a plurality of guide protrusions slidably disposed in the plurality of guide grooves.

[0008] In some embodiments, the rotating unit further includes a rotating rod that is linked to the rotating member and can rotate relative to the base about the second rotation axis, the rotating rod having the first connecting protrusion located at its end.

[0009] In some embodiments, the rotating unit further includes a transmission gear set connected between the rotating member and the rotating rod. The transmission gear set includes a driving gear and a driven gear. The driving gear is sleeved on the rotating member and rotates synchronously with the rotating member. The driven gear is disposed on the base and meshes with the driving gear. The rotating rod is disposed on the driven gear and rotates synchronously with the driven gear.

[0010] In some embodiments, the rotating foot pad has a first foot pad portion relatively close to the pivot portion and a second foot pad portion relatively far from the pivot portion; when the rotating foot pad is in the folded position, the first foot pad portion is lower than the second foot pad portion; when the rotating foot pad is in the upright position, the second foot pad portion is lower than the first foot pad portion.

[0011] The rotating foot in the hinge of this invention can be linked to the rotating component via the translational sliding component. When the rotating component rotates from the first position to the second position, the rotating foot can be rotated downwards from the folded position to the upright position. Therefore, when the hinge is used in electronic devices such as laptops, the rotating foot can be used to conveniently elevate the back of the laptop when using it. Attached Figure Description

[0021] See Figures 1 to 3This utility model discloses an embodiment of the hinge 100, applicable to an electronic device 200, exemplified by a laptop computer, but not limited thereto. The electronic device 200 has a first housing 201 and a second housing (not shown). The first housing 201 may, for example, include a keyboard, a screen, and a touch area (not shown). The hinge 100 connects the first housing 201 and the second housing, allowing the second housing to open and close relative to the first housing 201. The hinge 100 includes a base 1, a rotating unit 2, a translational slider 3, and rotating feet 4.

[0022] See Figures 1 to 4 The base 1 is adapted to be disposed on the first housing 201. The base 1 includes a first seat body 11 and a second seat body 12 arranged in a left-right direction D1, the first seat body 11 and the second seat body 12 being disposed on the rear side of the first housing 201 in a front-rear direction D2. The first seat body 11 of the base 1 has two guide grooves 111 formed recessedly in the left-right direction D1 and extending in the front-rear direction D2, the two guide grooves 111 being arranged, for example, in the front-rear direction D2.

[0023] See Figures 1 to 5The rotating unit 2 includes a rotating component 21, a rotating rod 22, and a transmission gear set 23. The rotating component 21 is disposed on the base 1 and houses the second housing. The rotating component 21 can rotate relative to the base 1 around a first rotation axis A1 parallel to the left-right direction D1 between a first position and a second position. The rotating component 21 also passes through a transition position during its rotation between the first and second positions. The rotating rod 22 has a first connecting protrusion 221 at its end. The transmission gear set 23 connects the rotating component 21 and the rotating rod 22. The transmission gear set 23 includes a driving gear 231 and a driven gear 232 located between a first seat 11 and a second seat 12 of the base 1. The driving gear 231 is sleeved on the rotating component 21 and rotates synchronously with the rotating component 21 around the first rotation axis A1. The driven gear 232 is disposed on the base 1 and meshes with the driving gear 231. The rotating rod 22 is disposed on the driven gear 232 and rotates synchronously with the driven gear 232. Through the transmission gear set 23, the first connecting protrusion 221 (and the entire rotating rod 22) is linked to the rotating member 21 and can rotate relative to the base 1 about a second rotation axis A2 parallel to the left-right direction D1. The rotation directions of the first connecting protrusion 221 (the entire rotating rod 22) and the rotating member 21 are opposite to each other. It should be noted that in other embodiments, the first connecting protrusion 221 can also be directly formed on the rotating member 21. In such embodiments, the second rotation axis A2 coincides with the first rotation axis A1, and the rotation axis and rotation direction of the first connecting protrusion 221 and the rotating member 21 are consistent.

[0024] The translational slider 3 is disposed on the base 1. The translational slider 3 has two guide protrusions 31 that protrude along the left-right direction D1 and are slidably disposed in the two guide grooves 111, thereby allowing the translational slider 3 to slide relative to the base 1 along the front-back direction D2 between a third position and a fourth position. The translational slider 3 has a first concave rail 32 and a second concave rail 33 formed recessed along the left-right direction D1. The first concave rail 32 has a connected drive rail portion 321 and an arc-shaped rail portion 322. The radius of curvature of the arc-shaped rail portion 322 is equal to the distance between the first connecting protrusion 221 and the second rotation axis A2. In this embodiment, the drive rail portion 321 is straight and tangent to the arc-shaped rail portion 322. However, in other embodiments, the structure of the drive rail portion 321 can be adjusted as needed and is not straight, and is not limited to this embodiment. The first connecting protrusion 221 of the rotating unit 2 is slidably disposed within the first concave rail 32, and the second concave rail 33 extends in the vertical direction D3.

[0025] The rotating foot pad 4 is located between the base 1 and the translational sliding member 3 and is pivotally mounted on the base 1. The rotating foot pad 4 can rotate relative to the base 1 about a third rotation axis A3 parallel to the left-right direction D1 between a folded position and an upright position. The rotating foot pad 4 has a second connecting protrusion 41 located at one end and slidably disposed within the second concave rail 33, a foot pad body 42 located at the other end, and a pivot portion 43 located between the second connecting protrusion 41 and the foot pad body 42 and pivotally connected to the base 1. The second concave rail 33 can absorb the displacement of the second connecting protrusion 41 in the up-down direction D3 when the rotating foot pad 4 rotates. The foot pad body 42 of the rotating foot pad 4 has a first foot pad portion 421 relatively close to the pivot portion 43 and a second foot pad portion 422 relatively far away from the pivot portion 43.

[0026] In addition, in this embodiment, a torsional friction element 5 that rotates synchronously with the rotating element 21 can be added to the rotating element 21. The torsional friction element 5 is used to generate a frictional force between itself and the second seat body 12 of the base 1 to resist the rotation of the rotating element 21, thereby enabling the electronic device 200 to be positioned at various opening and closing angles and improving the user's operating feel when opening and closing the electronic device 200.

[0027] See Figure 1 When the rotating member 21 is in the first position, the second housing is closed relative to the first housing 201. At this time, the first connecting protrusion 221 is located at the junction of the drive rail 321 and the arcuate rail 322, the translational sliding member 3 is located in the third position, and the rotating foot pad 4 is located in the retracted position. It should be noted that although the first connecting protrusion 221 is located at the junction of the drive rail 321 and the arcuate rail 322 at this time, depending on the shape of the drive rail 321 and the planned movement path of the first connecting protrusion 221, the first connecting protrusion 221 may also be located on the drive rail 321, rather than at the junction of the drive rail 321 and the arcuate rail 322, and is not limited to this embodiment. In this state, the foot pad body 42 of the rotating foot pad 4 is relatively close to the base 1, and the position of the first foot pad 421 is lower than that of the second foot pad 422.

[0028] See Figure 6When the rotating member 21 rotates from the first position to the transition position, and the second housing is opened about 45 degrees relative to the first housing 201, the first connecting protrusion 221 slides toward the drive rail 321 to the end of the drive rail 321, thereby driving the translational sliding member 3 to slide backward toward the fourth position along the front-back direction D2, and driving the rotating foot pad member 4 to rotate toward the support position.

[0029] See Figure 7 When the rotating member 21 continues to rotate to the transition position, the second housing opens approximately 90 degrees relative to the first housing 201. At this time, the first connecting protrusion 221 returns to the junction of the drive rail 321 and the arc-shaped rail 322. The first connecting protrusion 221 drives the translational slider 3 to slide along the front-rear direction D2 to the fourth position, thereby driving the rotating foot pad 4 to rotate to the supported position. In this state, the foot pad body 42 of the rotating foot pad 4 is relatively far away from the base 1, and the position of the second foot pad 422 is lower than that of the first foot pad 421. It is worth mentioning that the second foot pad 422 (the position for supporting on the table) of the foot pad body 42 of the rotating foot pad 4 is approximately located below the pivot part 43 of the rotating foot pad 4. Therefore, the reaction force on the foot pad body 42 of the rotating foot pad 4 is unlikely to generate a torque that forces the rotating foot pad 4 to rotate relative to the base 1, thus preventing the rotating foot pad 4 from rotating back to the folded position.

[0030] See Figure 8 When the rotating member 21 rotates from the transition position to the second position, the second housing opens approximately 180 degrees relative to the first housing 201. The first connecting protrusion 221 slides along the arc-shaped rail 322 to the end of the arc-shaped rail 322. The translational slider 3 does not slide, and the rotating foot pad 4 does not rotate. It should be noted that since the distance between the first connecting protrusion 221 of the rotating rod 22 and the second rotation axis A2 is fixed and equal to the radius of curvature of the arc-shaped rail 322, when the first connecting protrusion 221 is located on the arc-shaped rail 322, the translational slider 3 is restricted to the fourth position and cannot slide. Therefore, the rotating foot pad 4 is also restricted to the upright position and cannot rotate, thereby preventing the rotating foot pad 4 from rotating back to the folded position.

[0031] In summary, the rotating foot pad 4 in the pivot 100 of this utility model can be linked with the rotating member 21 through the translational slider 3. When the rotating member 21 rotates from the first position to the second position, the rotating foot pad 4 can be rotated downwards from the folded position to the upright position. Therefore, when the pivot 100 is applied to an electronic device 200 such as a laptop, the rotating foot pad 4 can be used to conveniently elevate the back of the laptop when using it. Furthermore, due to the design of the drive rail portion 321 and the arc-shaped rail portion 322 of the first concave rail 32, when the first connecting protrusion 221 is located on the arc-shaped rail portion 322, the translational slider 3 is restricted to the fourth position and cannot slide, and the rotating foot pad 4 is restricted to the upright position and cannot rotate, thereby preventing the rotating foot pad 4 from rotating back to the folded position.

[0032] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
