Description

Electronic devices

The present invention relates to an electronic device.

The usage modes of an electronic device (e.g., a laptop) may include a closed mode and a tablet mode. The tablet mode means that the display surface of the electronic device faces outward and the electronic device can be used as a tablet. The closed mode means that the display surface of the electronic device faces inward and cannot display. The usage modes of today's electronic devices are limited by their hinge assemblies. When switching between the closed mode and the tablet mode, the two bodies of the electronic device cannot remain parallel. The two bodies are tilted relative to each other and a gap is generated, which is inconvenient to use.

The present invention provides an electronic device that is easy to use.

The electronic device of the present invention comprises a first body, a support frame, a second body and at least one pivot assembly. The support frame comprises a first side and a second side opposite to each other, the first side being pivotally connected to the first body. The second body being pivotally connected to the second side. Each pivot assembly comprises a first rod, a second rod, a first rotating assembly, a second rotating assembly and a connecting rod. The first rod is connected to the first body, and the second rod is connected to the first side. The first rotating assembly is movably connected to the first rod and the second rod. The second rotating assembly is pivotally connected to the second side and the second body. The connecting rod extends along a first axis, is connected to the first rotating assembly and is suitable for abutting against the second rotating assembly. The rotation of the second body relative to the support frame drives the rotation of the second rotating assembly, and the second rotating assembly is suitable for driving the connecting rod to move along the first axis to lock or unlock the first rotating assembly.

Based on the above, the hinge assembly of the electronic device of the present invention is connected to the first body and the support frame through the first rotating assembly, and is connected to the second body and the support frame through the second rotating assembly. The connecting rod is located between the first rotating assembly and the second rotating assembly. Through the rotation of the second body relative to the support frame, the second rotating assembly can drive the connecting rod to lock or unlock the first rotating assembly. In this way, whether the electronic device is in closed mode or tablet mode, the second body is stacked in parallel with the first body, making the electronic device convenient to use.

Please refer to Figures 1 to 5 at the same time. The electronic device 100 includes a first body 110, a support frame 120, a second body 130 and at least one hinge assembly 200. The first body 110 includes a first end 112 and a second end 114 opposite to each other, and the second body 130 includes a third end 132 and a fourth end 134 opposite to each other. The support frame 120 includes a first side 122 and a second side 124 opposite to each other. The first side 122 is rotatably connected to the second end 114 of the first body 110, and the second side 124 is rotatably connected to the second body 130 and is located between the third end 132 and the fourth end 134. The number of hinge assemblies 200 is two, but not limited thereto. The electronic device 100 is, for example, a notebook computer, but not limited thereto.

The second body 130 further includes a display surface 138. Each hinge assembly 200 movably connects the first body 110 and the support frame 120, and connects the support frame 120 and the second body 130. The electronic device 100 can switch between a first state M1 (FIG. 1), a second state M2 (FIG. 9), and a third state M3 (FIG. 19) through the hinge assembly 200, so that the display direction of the display surface 138 of the second body 130 is changed to cope with different usage scenarios.

As shown in FIGS. 2 to 4 , the pivot assembly 200 includes a first rod 500, a second rod 600, a first rotating assembly 300, a second rotating assembly 700, and a connecting rod 400. The first rod 500 is connected to the first body 110, and the second rod 600 is connected to the first side 122 of the support frame 120. The first rotating assembly 300 is movably connected to the first rod 500 and the second rod 600, and the second rotating assembly 700 is rotatably connected to the second side 124 of the support frame 120 and the second body 130 ( FIG. 1 ). The connecting rod 400 extends along a first axis L1 and is slidably connected to the support frame 120. The support frame 120 limits the connecting rod 400 from sliding along the first axis L1. One end of the connecting rod 400 is connected to the first rotating assembly 300, and the other end can abut against the second rotating assembly 700.

The rotation of the support frame 120 (second body 130) relative to the first body 110 will drive the second rod 600 and the first rotating assembly 300 to rotate, and the first rotating assembly 300 can lock or unlock the second rod 600. The rotation of the second body 130 relative to the support frame 120 will drive the second rotating assembly 700 to rotate, so as to drive the connecting rod 400 to move along the first axis L1, thereby locking or unlocking the first rotating assembly 300.

As shown in FIGS. 1 to 3 , the second rotating assembly 700 includes a cam 710, a third rod 720, a support frame connector 730 and a body connector 740. The support frame connector 730 is connected to the support frame 120 and the third rod 720. The body connector 740 and the cam 710 are rotatably connected to the third rod 720 along a connecting axis L3. The body connector 740 and the cam 710 can rotate with the connecting axis L3 as a rotating axis. The connecting axis L3 is the central axis of the third rod 720. The connecting axis L3 is different from the first axis L1, and there may be an angle between the connecting axis L3 and the first axis L1. Preferably, the angle is 90 degrees, so that the connecting axis L3 is perpendicular to the first axis L1, and the connecting axis L3 can be parallel to the Y axis. The support frame connector 730 is connected to the support frame 120 and the third rod 720. The body connector 740 is connected to the second body 130. The connecting rod 400 can abut against the cam 710.

The cam 710 includes a main body 712 and a protrusion 714 connected to each other. The main body 712 is rotatably connected to the third rod 720 and is linked to the second body 130 (body connector 740). A geometric center 716 of the cam 710 is offset from the connection axis L3. When the second body 130 rotates relative to the support frame 120, the body connector 740 rotates relative to the third rod 720 with the connection axis L3 as the rotation axis, and drives the cam 710 to rotate, so that the protrusion 714 of the cam 710 can rotate relative to the connecting rod 400. The protrusion 714 can face or face away from the connecting rod 400.

Since the geometric center 716 of the cam 710 is misaligned with the connecting axis L3, the rotation of the protrusion 714 of the cam 710 will cause the connecting rod 400 to move along the first axis L1 relative to the first rotating assembly 300. When the protrusion 714 faces away from the connecting rod 400, the first rotating assembly 300 is locked. When the protrusion 714 faces toward the connecting rod 400, the connecting rod 400 abuts against the protrusion 714, and the first rotating assembly 300 is unlocked.

As shown in FIG. 2 and FIG. 3 , the first rotating assembly 300 includes a sliding member 310, a locking member 320, a first sleeve 340, a second sleeve 350, a slider 360 and a stopper 370. The sliding member 310 and the locking member 320 form a first module 300a. The second sleeve 350, the slider 360 and the stopper 370 form a second module 300b. The first module 300a is connected to the connecting rod 400 and is linked to the second module 300b. The second rotating assembly 700 can drive the connecting rod 400 through the rotation of the cam 710 to lock or unlock the first module 300a. The first module 300a and the second module 300b cooperate with each other to limit the rotation and rotation direction of the first rotating assembly 300.

The sliding member 310 includes a first sliding member 311 and a second sliding member 312. The first sliding member 311 of the sliding member 310 is slidably connected to the first rod 500 and the second rod 600, and can rotate relative to the first rod 500. The first sliding member 311 can slide relative to the first rod 500 and the second rod 600 along a second axis L2, and can rotate relative to the first rod 500 with an extended axis L4 as a rotation axis. The second sliding member 312 is slidably connected to the second rod 600, and can be rotatably connected to the first sliding member 311. The second sliding member 312 can slide relative to the second rod 600 along the second axis L2, and slide relative to the first sliding member 311 with the second axis L2 as the rotation axis. The second axis L2 is perpendicular to the first axis L1 and parallel to the connecting axis L3 (i.e., the Y axis). The extended axis L4 is parallel to the second axis L2. The second axis L2 is the central axis of the second rod 600, and the extended axis L4 is the central axis of the first rod 500.

As shown in FIG. 2 and FIG. 3 , the sliding member 310 further includes an inclined groove 313, and the inclined groove 313 is located on the second sliding member 312. The extension line of the inclined groove 313 is inclined to the first axis L1 and the second axis L2. The connecting rod 400 is movably connected to the inclined groove 313 of the sliding member 310 (the second sliding member 312) through a connecting member F1. The locking member 320 is connected to the first rod 500 along the extension axis L4. When the connecting rod 400 moves along the first axis L1, the second sliding member 312 of the sliding member 310 slides along the second axis L2 relative to the second rod 600 and pushes the first sliding member 311. The sliding member 310 (first sliding member 311) can slide close to the locking member 320 and engage with the locking member 320 to limit the rotation of the first module 300a. The sliding member 310 (first sliding member 311) can also slide away from the locking member 320 to disengage from the locking member 320.

The sliding member 310 of this embodiment further includes a first boss 314 and a second boss 315, and the locking member 320 includes a first groove 322. The first boss 314 is located at one end E1 of the first sliding member 311 corresponding to the first rod 500, and the second boss 315 is located at the other end E2 of the first sliding member 311 corresponding to the second rod 600. The first boss 314 (sliding member 310) corresponds to the first groove 322 (locking member 320), and when the first boss 314 is engaged with the first groove 322, the first sliding member 311 of the sliding member 310 is locked.

As shown in FIG. 2 and FIG. 4 , the second rod 600 includes a second groove 610, and the second boss 315 can be located in the second groove 610. When the second rod 600 rotates relative to the sliding member 310 (first sliding member 311) with the second axis L2 as the rotation axis, the second groove 610 can rotate relative to the second boss 315. The second boss 315 can limit the rotation angle of the second groove 610 (second rod 600) to limit the rotation angle of the support frame 120 relative to the first body 110.

As shown in FIG. 2 , the sliding member 310 includes a third boss 317 and a third groove 316. The third groove 316 is located at the end E2 of the first sliding member 311, and the third boss 317 and the inclined groove 313 are located at the opposite ends E3 and E4 of the second sliding member 312. The third groove 316 surrounds the second axis L2. The third boss 317 is located in the third groove 316. When the second rod 600 rotates relative to the first sliding member 311, the second sliding member 312 rotates with the second rod 600, and the third boss 317 can slide in the third groove 316. When the second sliding member 312 moves along the second axis L2, the third boss 317 can push against the third groove 316, and push the first sliding member 311 to move along the second axis L2.

The first rotating assembly 300 further includes an elastic member 330, which is connected to the second sliding member 312 of the sliding member 310 and the second rod 600. The elastic member 330 is used to provide elastic force to enable the sliding member 310 to slide relative to the second rod 600.

As shown in FIG. 3 and FIG. 5 , the first sleeve 340 of the first rotating assembly 300 is connected to the first rod 500 along the extension axis L4, and includes a first arc surface 341 and a first recess 342 connected to each other. The second sleeve 350 is connected to the second rod 600 along the second axis L2, and includes a second arc surface 351 and a second recess 352 connected to each other. The second sleeve 350 can rotate with the second rod 600. The slider 360 includes a first surface 362 and a second surface 364 opposite to each other. The curvature of the first recess 342 corresponds to the curvature of the first surface 362, and the curvature of the second recess 352 corresponds to the curvature of the second surface 364. The first arc surface 341 and the first recess 342 form a side surface 344 of the first sleeve 340. The second arc surface 351 and the second recess 352 form a side surface 354 of the second sleeve 350. The slider 360 can slide between the first sleeve 340 and the second sleeve 350.

The first sleeve 340, the second sleeve 350 and the slider 360 are movably connected to the limiter 370. The limiter 370 includes a first limiter column 372 and a second limiter column 374. The first sleeve 340 includes a first limiter groove 343, and the second sleeve 350 includes a second limiter groove 353. The first limiter column 372 and the second limiter column 374 are respectively located in the corresponding first limiter groove 343 and the second limiter groove 353 to limit the rotation angle of the limiter 370 and the second sleeve 350 (the second rod 600). The first limiter groove 343 is located on a bottom surface 345 of the first sleeve 340, and the second limiter groove 353 is located on a bottom surface 355 of the second sleeve 350. The first rod 500 and the second rod 600 are penetrated by the limiter 370.

In addition, as shown in FIG. 2 and FIG. 3 , the second rod 600 of the present embodiment includes a first portion 620 and a second portion 630 connected to each other, but is not limited thereto. The extension axis L4 is the central axis of the first portion 620, and the first sliding member 311 is connected to the first portion 620. The second sliding member 312 further includes a slide groove 318. A link F2 passes through the slide groove 318 and is connected to the second portion 630. The slide groove 318 extends along the second axis L2 to limit the sliding direction of the second sliding member 312 relative to the second rod 600. The pivot assembly 200 further includes two torque assemblies 800, which are respectively connected to the first rod 500 and the second rod 600 to provide torque. The second body 130 further includes a receiving groove 136 (FIG. 1), and the receiving groove 136 can be used to receive the supporting frame 120.

FIG. 1 to FIG. 5 show the electronic device 100 in the first state M1, and the first state M1 can be regarded as a closed state in the laptop mode. As shown in FIG. 1 and FIG. 4, in the first state M1, the first end 112 of the first body 110 corresponds to the third end 132 of the second body 130, and the second end 114 corresponds to the fourth end 134. That is, the first end 112 is adjacent to the third end 132; the second end 114 is adjacent to the fourth end 134. The second body 130 is located between the first body 110 and the support frame 120. The display surface 138 of the second body 130 faces the first body 110. The support frame 120 is located outside the receiving groove 136, and the first body 110 is parallel to the second body 130.

As shown in FIG. 2 , in the first state M1, the body connector 740 of the second rotating assembly 700 is located at the position shown in FIG. 2 , so that the protrusion 714 of the cam 710 faces and abuts against the connecting rod 400. The connecting member F1 connected to the connecting rod 400 corresponds to one end E5 of the inclined groove 313 of the sliding member 310. The cam 710 abuts against the connecting rod 400 through the protrusion 714, so that the sliding member 310 is positioned at the position shown in FIG. 2 , so that the sliding member 310 and the locking member 320 are staggered on the extension axis L4, and the first boss 314 is misaligned with the first groove 322, and the first boss 314 abuts against the locking member 320. The second boss 315 of the sliding member 310 (first sliding member 311) is located in the second groove 610 of the second rod 600. The elastic member 330 is deformed and accumulates elastic force. At this time, the first rotating assembly 300 is unlocked, and the sliding member 310 can rotate relative to the first rod 500.

As shown in FIG. 5 , in the first state M1, the first arc surface 341 of the first sleeve 340 abuts against the first surface 362 of the slider 360, and the second recess 352 of the second sleeve 350 abuts against the second surface 364 of the slider 360. The first limiting column 372 of the limiting member 370 abuts against one side S2 of the first limiting groove 343 of the first sleeve 340. Thus, the first sleeve 340, the slider 360 and the second sleeve 350 cannot rotate or move relative to each other. The pivot assembly 200 limits the rotation of the second rod 600 through the slider 360 and the second sleeve 350 of the second module 300b, and limits the rotation direction of the limiting member 370 through the limiting member 370 of the second module 300b, thereby limiting the rotation direction of the first module 300a.

In short, in the first state M1, the cam 710 positions the slider 310 at the position shown in FIG. 2 through the connecting rod 400. The second rod 600, the slider 310 of the first module 300a and the second module 300b can extend the axis L4 as the rotation axis and rotate relative to the first rod 500. The first limit column 372 of the limit member 370 limits the rotation direction of the first module 300a and the second module 300b, and the first module 300a and the second module 300b can rotate clockwise. The second module 300b locks the second rod 600 so that the second rod 600 does not rotate with the second axis L2 as the rotation axis.

FIG6 is a schematic diagram of the hinge assembly of the electronic device of FIG1 after the second body is rotated. FIG7 is a cross-sectional view of the electronic device of FIG6. FIG8 is another cross-sectional view of the electronic device of FIG6. Please refer to FIG6 to FIG8 simultaneously. When the electronic device 100 is to be switched from the first state M1 of FIG1 to the second state M2 (FIG9), the third end 132 (FIG1) of the second body 130 can be subjected to force, so that the second body 130 is opened relative to the first body 110, and the second body 130 drives the support frame 120 to rotate relative to the first body 110 to the position of FIG7. The rotation angle A1 of the second body 130 (support frame 120) relative to the first body 110 is, for example, 50 degrees, but is not limited thereto.

As shown in FIG6 , at this time, the second body 130 and the support frame 120 do not rotate relative to each other, so that the protrusion 714 of the cam 710 of the second rotating assembly 700 still faces and abuts against the connecting rod 400. The rotation of the support frame 120 drives the second rod 600, the sliding member 310 and the second module 300b of the pivot assembly 200 to rotate to the position of FIG6 with the extension axis L4 as the rotation axis. As shown in FIG6 and FIG7 , the sliding member 310 rotates relative to the locking member 320, so that the first boss 314 of the sliding member 310 is aligned with the first groove 322 of the locking member 320. The first boss 314 and the locking member 320 are staggered on the extension axis L4.

As shown in FIG8 , the second module 300b rotates relative to the first sleeve 340 (first rod 500), so that the first limiting column 372 of the limiting member 370 abuts against the other side S3 of the first limiting groove 343 of the first sleeve 340, so as to limit the rotation angle A1 of the second body 130 (support frame 120) relative to the first body 110, and limit the rotation direction of the first module 300a and the second module 300b. At this time, the first surface 362 of the slider 360 corresponds to the first recess 342 of the first sleeve 340, and there is a gap G1 between the first recess 342. The second surface 364 of the slider 360 still abuts against the second recess 352 of the second sleeve 350.

In short, the position limiter 370 limits the rotation direction of the first rotating assembly 300, so that the first module 300a (sliding member 310) and the second module 300b do not rotate clockwise with the extended axis L4 as the rotation axis. Since there is a gap G1 between the slider 360 and the first sleeve 340, the second rod 600 (second sleeve 350) can rotate with the second axis L2 as the rotation axis.

FIG9 is a schematic diagram of the electronic device of FIG6 in the second state. FIG10 is a schematic diagram of the pivot assembly of the electronic device of FIG9. FIG11 is a cross-sectional view of the pivot assembly of FIG10. FIG12 is another cross-sectional view of the pivot assembly of FIG10. Please refer to FIG9 to FIG12 at the same time. The third end 132 (FIG. 1) of the second body 130 can be continuously subjected to force, so that the electronic device 100 switches from the position of FIG7 to the second state M2 of FIG9. In this process, the second body 130 (support frame 120) drives the second rod 600 to rotate with the second axis L2 as the rotation axis, thereby driving the second sliding member 312 and the second sleeve 350 to rotate.

In the second state M2, the rotation angle A2 of the second body 130 relative to the first body 110 is, for example, 130 degrees, but is not limited thereto. The second state M2 can be regarded as an unfolded state in the laptop mode. The second body 130 is unfolded relative to the first body 110, and the second end 114 of the first body 110 corresponds to the fourth end 134 of the second body 130. That is, the distance between the second end 114 and the fourth end 134 is smaller than the distance between the first end 112 and the fourth end 134, the second end 114 is adjacent to the fourth end 134, and the second end 114 is aligned with the fourth end 134. The display surface 138 of the second body 130 faces forward (i.e., the +X axis direction). The protrusion 714 of the cam 710 still faces and abuts against the connecting rod 400. The electronic device 100 can be used as a general notebook computer.

As shown in Figures 10 and 11, the second rod 600 drives the second slider 312 to rotate relative to the first slider 311, so that the third boss 317 slides in the third groove 316. In the second state M2, one side S1 of the second groove 610 of the second rod 600 abuts against the second boss 315 of the slider 310 (first slider 311) to limit the rotation angle A2 of the second rod 600 (support frame 120 and second body 130). The first slider 311 does not rotate, so that the first boss 314 is still aligned with the first groove 322 of the locking member 320, but is offset on the extension axis L4.

As shown in Figures 10 and 12, the rotation of the second rod 600 further drives the second sleeve 350 to rotate relative to the first sleeve 340 and the stopper 370, and the second arc surface 351 of the second sleeve 350 pushes the slider 360, so that the slider 360 moves toward the first sleeve 340. In the second state M2, the first recess 342 of the first sleeve 340 abuts against the first surface 362 of the slider 360, and the second arc surface 351 of the second sleeve 350 abuts against the second surface 364 of the slider 360. The first stopper column 372 of the stopper 370 still abuts against the side S3 of the first stopper groove 343, and the second stopper column 374 abuts against one side S4 of the second stopper groove 353 of the second sleeve 350 to limit the rotation direction of the second rod 600. The second rod 600 can rotate counterclockwise.

In short, in the second state M2, the stopper 370 of the second module 300b still limits the rotation direction of the first rotating assembly 300 with the extension axis L4 as the rotation axis. The second stopper column 374 of the stopper 370 limits the rotation direction of the second rod 600 (second sleeve 350), so that the second body 130 cannot be further opened relative to the first body 110.

FIG13 is a schematic diagram of the hinge assembly of the electronic device of FIG9 after the second body is rotated. FIG14 is a cross-sectional view of the electronic device of FIG13. FIG15 is another cross-sectional view of the electronic device of FIG13. Please refer to FIG13 to FIG15 at the same time. When the electronic device 100 is to be switched from the second state M2 to the third state M3 (FIG19), the third end 132 of the second body 130 is first subjected to force, so that the second body 130 is rotated 180 degrees relative to the support frame 120 and is located at the position of FIG14. At this time, the third end 132 of the second body 130 corresponds to the second end 114 of the first body 110, and the display surface 138 of the second body 130 faces backward (i.e., -X axis direction).

As shown in FIG13 , the rotation of the second body 130 drives the body connector 740 of the second rotating assembly 700 to rotate, and the body 712 of the cam 710 rotates with the body connector 740, so that the protrusion 714 of the cam 710 faces away from the connecting rod 400. When the cam 710 rotates, the cam 710 releases the connecting rod 400, and the connecting rod 400 can move along the first axis L1. The connecting member F1 connected to the connecting rod 400 corresponds to the other end E6 of the inclined slot 313.

Since the connecting rod 400 is released, the sliding member 310 of the first rotating assembly 300 moves toward the locking member 320 along the second axis L2 through the elastic force of the elastic member 330, so that the first protrusion 314 of the sliding member 310 is engaged with the first groove 322 of the locking member 320 to limit the rotation of the first sliding member 311 of the sliding member 310. The first sliding member 311 does not rotate around the extension axis L4. At this time, the second protrusion 315 of the sliding member 310 moves away from the second groove 610 of the second rod 600, and the second protrusion 315 and the second groove 610 are staggered on the second axis L2.

As shown in FIG. 15 , the first limiting column 372 of the limiting member 370 of the second module 300b still abuts against the edge S3 of the first limiting groove 343, and the second limiting column 374 still abuts against the edge S4 of the second limiting groove 353 of the second sleeve 350.

In short, at this time, the sliding member 310 is locked by the locking member 320, so that the first sliding member 311, the second rod 600 and the second module 300b do not rotate with the extended axis L4 as the axis. The second limiting column 374 of the limiting member 370 limits the rotation direction of the second rod 600 (second sleeve 350), and the second rod 600 (second sleeve 350) can rotate counterclockwise with the second axis L2 as the axis.

FIG. 16 is a schematic diagram of the hinge assembly after the second body of the electronic device of FIG. 13 rotates. FIG. 17 is a cross-sectional view of the electronic device of FIG. 16. FIG. 18 is another cross-sectional view of the electronic device of FIG. 16. Referring to FIG. 16 to FIG. 18, the second body 130 can be further subjected to force, so that the second body 130 switches from the position of FIG. 14 to the position of FIG. 17. The rotation of the second body 130 (support frame 120) drives the second rod 600, the second slider 312 and the second sleeve 350 to rotate around the second axis L2, so that the second recess 352 of the second sleeve 350 is aligned with the second surface 364 of the slider 360. There is a gap G2 between the second recess 352 and the second surface 364, so that the second rod 600 can continue to rotate.

FIG. 19 is a schematic diagram of the electronic device of FIG. 16 in the third state. FIG. 20 is a schematic diagram of the pivot assembly of FIG. 19. FIG. 21 is a cross-sectional view of the electronic device of FIG. 19. FIG. 22 is another cross-sectional view of the electronic device of FIG. 19. Please refer to FIG. 19 to FIG. 22 at the same time. The second body 130 can be further stressed from the position of FIG. 17, so that the electronic device 100 switches to the third state M3 of FIG. 19. The rotation of the second body 130 (support frame 120) drives the second rod 600 to rotate, and drives the second sliding member 312 and the second sleeve 350 to rotate with the second axis L2 as the axis.

As shown in FIG. 19 and FIG. 20 , in the third state M3, the first end 112 of the first body 110 corresponds to the fourth end 134 of the second body 130, and the second end 114 corresponds to the third end 132. That is, the first end 112 is adjacent to the fourth end 134; the second end 114 is adjacent to the third end 132. The protrusion 714 of the cam 710 faces away from the connecting rod 400. The display surface 138 of the second body 130 faces away from the first body 110 and is displayed outwardly, and the electronic device 100 can be used as a tablet computer, which means that the third state M3 can be regarded as the use state of a tablet computer. The support frame 120 is accommodated in the accommodating groove 136 of the second body 130, so that the first body 110 is parallel to the second body 130.

As shown in FIG. 21 , in the third state M3, the second arc surface 351 of the second sleeve 350 abuts against the second surface 364 of the slider 360. The first recess 342 of the first sleeve 340 still abuts against the first surface 362 of the slider 360. The second limiting column 374 of the limiting member 370 abuts against one side S5 of the second sleeve 350 to limit the rotation direction of the second sleeve 350 (second rod 600).

In short, in the third state M3, the sliding member 310 (first protrusion 314) of the first module 300a is still engaged with the locking member 320 (second groove 610), thereby limiting the rotation of the first sliding member 311 and the stopper 370 of the first rotating assembly 300. The first rotating assembly 300 does not rotate around the extended axis L4. The second rod 600, the second sliding member 312 and the second sleeve 350 can rotate around the second axis L2.

When the electronic device 100 is to be switched from the third state M3 of FIG. 19 to the first state M1 of FIG. 1 , the electronic device 100 can be switched to the position of FIG. 14 first. The second body 130 is rotated by force, driving the second rod 600, the second sliding member 312 and the second sleeve 350 to rotate clockwise with the second axis L2 as the rotation axis. The second body 130 is opened relative to the first body 110.

Next, the second body 130 of the electronic device 100 can rotate 180 degrees relative to the support frame 120 and switch from the position of FIG. 14 to the position of FIG. 11, so that the electronic device 100 switches to the second state M2. At this time, the rotation of the cam 710 of the second rotating assembly 700 drives the connecting rod 400 and the sliding member 310, so that the sliding member 310 and the locking member 320 are released.

The second body 130 and the support frame 120 can continue to rotate toward the first body 110, so that the second body 130 is located in the position of Figure 8, and the second module 300b and the first sleeve 340 cooperate with each other to limit the rotation of the second rod 600. The second rod 600 does not rotate with the second axis L2 as the axis. Finally, the second body 130 and the support frame 120 further rotate toward the first body 110, and the sliding member 310 and the second module 300b rotate with the extension axis L4 as the axis, so that the electronic device 100 switches to the first state M1 of Figure 4.

It can be seen that through the cooperation of the first rotating assembly 300, the second rotating assembly 700 and the connecting rod 400 of the pivot assembly 200, the electronic device 100 can switch freely between the first state M1, the second state M2 and the third state M3.

In summary, the hinge assembly of the electronic device of the present invention is connected to the first body and the support frame through the first rotating assembly, and is connected to the second body and the support frame through the second rotating assembly. The connecting rod is located between the first rotating assembly and the second rotating assembly. Through the rotation of the second body relative to the support frame, the second rotating assembly can drive the connecting rod to lock or unlock the first rotating assembly. In this way, whether the electronic device is in closed mode or tablet mode, the second body is stacked in parallel with the first body, making the electronic device convenient to use.
