Abstract
Description
Technical Field
[0001] The present invention relates to a hinge, and particularly to a rotating shaft lifting hinge. Background Art
[0002] Currently, electronic devices such as laptop computers use existing hinges with no displacement of the rotating shaft. When the upper cover is opened, it will interfere with the chassis. Therefore, one of the upper cover or the chassis must be chamfered to avoid interference during opening. However, even with chamfering to avoid interference, there is an overlap between the upper cover and the chassis during the opening process, leaving little space between the two, which is not conducive to heat dissipation. Therefore, there is still room for improvement. Summary of the Invention
[0003] An object of the present invention is to provide a rotating shaft lifting hinge that can solve at least one of the above problems.
[0004] The rotating shaft lifting hinge of the present invention is suitable for being disposed between a first body and a second body. The rotating shaft lifting hinge includes:
[0005] A base unit, including a first base and a second base. The first base is suitable for connecting to the first body. The first base has a substrate, the substrate has a first side, a second side opposite to the first side, an upper side, and a lower side opposite to the upper side, and forms a movable groove. The movable groove has a first groove portion extending from the first side toward the second side and a second groove portion communicating with the first groove portion and extending from the first groove portion toward the upper side. The second base is suitable for connecting to the second body; and
[0006] A rotating unit, including a rotating shaft movably passing through the movable groove of the first base and fixedly passing through the second base, a connecting rod sleeved on the rotating shaft and pivotally disposed on the substrate, and a cam member fixedly sleeved on the rotating shaft. The cam member has an annular portion fixedly sleeved on the rotating shaft and a first convex portion protruding from the annular portion and movably disposed in the first groove portion. The second base can be driven to drive the rotating unit to rotate between an initial position and a first rotating position. In the initial position, the rotating shaft is located in the first groove portion, the first convex portion is located at one end of the first groove portion adjacent to the first side. The second base can drive the rotating shaft and the cam member to rotate. The first convex portion of the cam member can abut against the lower edge surface of the first groove portion to drive the rotating shaft to move to the second groove portion and drive the connecting rod to pivot upward to reach the first rotating position.
[0007] In some embodiments, the first base further has a side plate connecting to the first side, and the cam member further includes a second convex portion protruding from the annular portion. The second convex portion can abut against the side plate.
[0008] In some embodiments, the side plate extends vertically up and down.
[0009] In some embodiments, the side plate extends obliquely up and down, and the distance between the upper side of the side plate and the second side is less than the distance between the lower side of the side plate and the second side.
[0010] In some embodiments, the rotating unit can also reach a second rotation position. The end of the first groove away from the first side is in an upward arc shape. When in the second rotation position, the rotating shaft is also located in the second groove, and the first convex part is located at the end of the first groove away from the first side.
[0011] In some embodiments, the rotating unit can also reach a second rotation position.

[0036] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
[0037] Refer to Figures 1 to 3 , a first embodiment of the rotating shaft lifting hinge 10 of the present invention is applicable to be disposed between a first body 20 and a second body 30 to jointly form an electronic device 100. The electronic device 100 can be, for example, a folding device or a handheld device such as a mobile phone, a tablet, a tablet computer, a notebook computer, etc. In this embodiment, a notebook computer is taken as an example for illustration. The first body 20 is the part provided with a keyboard or a secondary screen and has a plurality of heat dissipation holes 201. The second body 30 is the part of the main screen. The rotating shaft lifting hinge 10 includes a base unit 1 and a rotating unit 2 (as Figure 4 shown).
[0038] Refer to Figure 4 and Figure 5, the base unit 1 includes a first base 3 and a second base 4. The first base 3 is adapted to connect to the first body 20. The first base 3 has a base plate 31, a side plate 32, and a connecting plate 33. The base plate 31 has a first side 311, a second side 312 opposite to the first side 311, an upper side 313, and a lower side 314 opposite to the upper side 313, and forms a movable slot 315. The movable slot 315 has a first slot portion 315a extending from the first side 311 towards the second side 312 and a second slot portion 315b communicating with the first slot portion 315a and extending from the first slot portion 315a towards the upper side 313. The portion of the first slot portion 315a adjacent to the first side 311 extends substantially horizontally, and the end away from the first side 311 is in an upward arc shape. The side plate 32 is connected to the first side 311 and extends vertically up and down. The connecting plate 33 is connected to a portion of the lower side 314 adjacent to the second side 312 and extends horizontally, and is adapted to connect to the first body 20. The second base 4 is adapted to connect to the second body 30.
[0039] The rotating unit 2 includes a rotating shaft 21 that movably passes through the movable slot 315 of the first base 3 and fixedly passes through the second base 4, a connecting rod 22 that movably sleeves on the rotating shaft 21 and is pivotally provided on the base plate 31, a cam member 23 fixedly sleeved on the rotating shaft 21, a friction plate 24 sleeved on the rotating shaft 21 and connected to the connecting rod 22, two torsion plates 25 movably sleeved on the rotating shaft 21, three spacers 26 fixedly sleeved on the rotating shaft 21, and a nut 27 screwed on the rotating shaft 21 and abutting against one of the torsion plates 25. The rotating shaft 21 has a first passing section 211 passing through the second base 4, the cam member 23, and one of the spacers 26, a connecting section 212 connecting the first passing section 211 for the connecting rod 22 to sleeve, a second passing section 213 connecting the connecting section 212 and passing through the friction plate 24, the torsion plates 25, and the remaining two spacers 26, and a threaded section 214 connecting the second passing section 213 for the nut 27 to be locked. The cam member 23 has an annular portion 231 fixedly sleeved on the rotating shaft 21, a first convex portion 232 protruding from the annular portion 231 and movably disposed in the first slot portion 315a, and a second convex portion 233 protruding from the annular portion 231. One of the spacers 26 abuts against the cam member 23, another spacer 26 abuts against the connecting rod 22 and the friction plate 24 respectively, and the last spacer 26 abuts against the friction plate 24 and one of the torsion plates 25 respectively. One end of the torsion plate 25 abuts against the spacer 26, and the other end abuts against the nut 27. The frictional force between the torsion plate 25, the spacer 26, and the nut 27 can provide the torque required for the rotation shaft lifting hinge 10 of the present invention to actuate, but the way of generating torque is not limited to this form.
[0040] Refer to Figures 6 to 11, the second base 4 can be driven to drive the rotating unit 2 to rotate between an initial position, a first rotating position, and a second rotating position. When in the initial position, the rotating shaft 21 is located in the first groove portion 315a, and the first convex portion 232 is located at one end of the first groove portion 315a adjacent to the first side 311, as Figure 6 and Figure 7 shown. When a user wants to use the electronic device 100, the second body 30 is opened relative to the first body 20 to drive the second base 4 to rotate, thereby driving the rotating shaft 21 and the cam member 23 to rotate. During the rotation, the first convex portion 232 of the cam member 23 can abut against the lower edge surface of the first groove portion 315a to drive the rotating shaft 21 to move to the second groove portion 315b and drive the connecting rod 22 to pivot upward, and the second convex portion 233 abuts against the side plate 32 to reach the first rotating position, as Figure 8 and Figure 9 shown. At this time, the position of the rotating shaft 21 is lifted, so that the projected length of the connecting rod 22 in the horizontal direction increases, and a larger gap is generated between the second body 30 and the first body 20. During the rotation of the second body 30, there will be no interference with the first body 20, and it can also allow the heat dissipation holes 201 (see Figure 2 ) at the rear end of the first body 20 to discharge hot air outward, which is beneficial to help the first body 20 dissipate heat. And by the second convex portion 233 abutting against the side plate 32, the overall mechanical stability of the rotating unit 2 can be improved without deviation. The user can also open the second body 30 relative to the first body 20 by a larger angle as needed to drive the second base 4 to rotate, thereby driving the rotating unit 2 to rotate to a second rotating position. When in the second rotating position, the rotating shaft 21 is also located in the second groove portion 315b, the second convex portion 233 also abuts against the side plate 32, and the first convex portion 232 is located at one end of the first groove portion 315a away from the first side 311 to limit the continuous rotation of the second base 4 and the second body 30, as Figure 10 and Figure 11 shown.
[0041] It should be noted that the side plate 32 that abuts against the second convex portion 233 is not limited to connecting the first side 311 of the base plate 31. In other embodiments, it can also be connected to the upper side 313 as long as it can abut against the second convex portion 233.
[0042] Referring to Figures 12 to 14 , a second embodiment of the rotating shaft lifting hinge 10' of the present invention is also applicable to be disposed between a first body 20 and a second body 30 to jointly form an electronic device 100'. Referring again to Figure 15 and Figure 16, wherein the side plate 32 of the second embodiment extends obliquely up and down, and the distance between the upper side of the side plate 32 and the second side 312 is smaller than the distance between the lower side of the side plate 32 and the second side 312. There are also slight differences in the first groove portion 315a of the movable groove 315 from the first embodiment. In the second embodiment, the portion of the first groove portion 315a adjacent to the first side 311 extends obliquely, and the end away from the first side 311 first bends in an arc towards the lower side 314 and then bends upwards. In addition, the length of the connecting rod 22 in the second embodiment is relatively shorter than that in the first embodiment, and the axis of the connecting rod 22 fixed to the substrate 31 is also closer to the first side 311 and closer to the lower side 314 compared with the first embodiment.
[0043] Refer to Figures 17 to 22 , the second base 4 can also be driven to drive the rotating unit 2 to rotate between an initial position, a first rotation position and a second rotation position. In the initial position, the rotating shaft 21 is located in the first groove portion 315a, and the first convex portion 232 is located at the end of the first groove portion 315a adjacent to the first side 311, as Figure 17 and Figure 18 shown. When a user wants to use the electronic device 100', the second body 30 is opened relative to the first body 20 to drive the second base 4 to rotate, thereby driving the rotating shaft 21 and the cam member 23 to rotate. The first convex portion 232 of the cam member 23 can abut against the lower edge surface of the first groove portion 315a during rotation to drive the rotating shaft 21 to move to the second groove portion 315b and drive the connecting rod 22 to pivot upwards, and the second convex portion 233 abuts against the side plate 32 to reach the first rotation position, as Figure 19 and Figure 20 shown. At this time, the position of the rotating shaft 21 is lifted, so that the projected length of the connecting rod 22 in the horizontal direction increases, and a gap is generated between the second body 30 and the first body 20. The second body 30 will not interfere with the first body 20 during rotation, and it can also allow the heat dissipation hole 201 (see Figure 13)The hot air is discharged outwards, which is beneficial to help the first body 20 dissipate heat. By means of the second convex portion 233 abutting against the side plate 32, the mechanical stability of the whole rotating unit 2 can be improved without deviation. The user can also open the second body 30 relative to the first body 20 at a larger angle as required to drive the second base 4 to rotate, and then drive the rotating unit 2 to rotate to a second rotation position. At the second rotation position, since one end of the first groove portion 315a far from the first side 311 bends downwards first, the rotating shaft 21 starts to move downwards along the second groove portion 315b to the vicinity of the first groove portion 315a, but still remains in the second groove portion 315b, so that the second body 30 will not interfere with the beveled corner at the rear end of the first body 20. The second convex portion 233 also abuts against the side plate 32, and the first convex portion 232 is located at one end of the first groove portion 315a far from the first side 311 to limit the second base 4 and the second body 30 from continuing to rotate, as Figure 21 and Figure 22 shown.
[0044] In summary, the rotating shaft lifting hinge 10, 10' of the present invention can drive the rotating shaft 21 and the cam member 23 through the second base 4. The first convex portion 232 of the cam member 23 can abut against the lower edge surface of the first groove portion 315a to drive the rotating shaft 21 to move to the second groove portion 315b and drive the connecting rod 22 to pivot upwards to reach the first rotation position. At this time, the position of the rotating shaft 21 is lifted, so that the projected length of the connecting rod 22 in the horizontal direction increases, and a gap is generated between the second body 30 and the first body 20. The second body 30 will not interfere with the first body 20 during the rotation process, so the purpose of the present invention can be truly achieved.
[0045] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still belong to the scope of the present invention.
