The engaging portion 256 extends from an edge of the mounting base body 255 near the first mounting base 251 toward one side of the display module 200.

The side of the linking part 256 facing the first mounting base 251 is provided with a plurality of first pivot holes 2561 engaged with the synchronous transmission assembly 28 and a plurality of second pivot holes 2562 engaged with the first rotating arm 26 and the second rotating arm 27. The axes of the first pivot holes 2561 and the second pivot holes 2562 are parallel to each other. The first pivot holes 2561 are adapted to cooperate with the synchronous drive assembly 28. One of the second pivot holes 2562 is used for mounting the first rotating arm 26, so that the first rotating arm 26 is rotatably connected to the second mounting base 252. The other second pivot hole 2562 is used for mounting the second rotating arm 27, so that the second rotating arm 27 is rotatably connected to the second mounting base 252.

It is understood that the second pivot holes 2562 are coaxially aligned with the pivot holes 2514 of the connecting lugs 2513 in a one-to-one correspondence. Such that a corresponding one of the second pivot holes 2562 and one of the attachment lugs 2513 is used to secure the first rotating arm 26 and a corresponding other one of the second pivot holes 2562 and another one of the attachment lugs 2513 is used to secure the second rotating arm 27.

rotating arms

26 and 27. The opening 2563 extends along a radial direction of the second pivot hole 2562. In an embodiment, the aperture of the second pivot hole 2562 near the first mounting base 251 is smaller than the aperture of the second pivot hole 2562 far from the first mounting base 251, so as to form a locking position for locking the first rotating arm 26 and the second rotating arm 27, and prevent the first rotating arm 26 and the second rotating arm 27 from being separated from the rotational connection with the second mounting base 252 in the axial direction of the second pivot hole 2562.

In one embodiment, the connecting portion 256 is provided with a first sub-pivot portion 2564 at a side away from the first mounting base 251 so as to be pivoted with the pivot assembly 22.

To place the second rotating arm 27 in a second pivot bore 2542 from an opening 2543. The extending direction of the opening 2543 and the extending direction of the opening 2563 form a spatial interference, that is, the opening 2543 and the opening 2563 are alternately arranged, so as to prevent the first rotating arm 26 and the second rotating arm 27 from being simultaneously separated from the opening 2543 and the opening 2563 from the second pivot hole 2542 and the second pivot hole 2562, and to fix the first rotating arm 26 and the second rotating arm 27.

In one embodiment, the second mounting base 252 may be replaced with the first mounting base 251 in FIG. 10. In an embodiment, the second mounting base 252 may replace the first mounting base 251 in fig. 10.

Referring to fig. 14 and fig. 15, a schematic structural diagram of the rotating arm in the embodiment of fig. 10 of the present application is respectively disclosed. The swivel arms may be two, such as a first swivel arm 26 and a second swivel arm 27. The swivel arms, such as the first swivel arm 26 and the second swivel arm 27, may include a sliding portion 261, a fixing portion 262 connected to the sliding portion 261, and a swivel portion 263 fixed to the fixing portion 262.

The sliding portion 261 may be made of a hard material. The sliding portion 261 has a guiding function. The sliding portion 261 may be a plate-shaped structure, a rod-shaped structure, or other structures, which are not limited herein. Here, the sliding portion 261 has a substantially plate-like structure. The sliding portion 261 is provided with a sub push-pull portion 2611 so as to be matched with the first support plate 30 or the second support plate 40. In one embodiment, the sub-push-pull portion 2611 is embodied as a pivot shaft. In one embodiment, the sliding portion 261 is provided with a notch 2612 at a position opposite to the sub push-pull portion 2611 so as to give way to the first supporting plate 30 or the second supporting plate 40.

The edge of the sliding portion 261 near the fixing portion 262 is provided with a first sub-contact portion 2613. The first sub-contact portion 2613 extends from the edge of the sliding portion 261 near the fixing portion 262 to the display module 200, bends toward the fixing portion 262, and is connected and fixed to the fixing portion 262.

The first sub-contact portion 2613 is fixedly connected to one side of the fixing portion 262 close to the display module 200. An abdicating space 264 for accommodating the support frame sidewall 12 of the spindle support frame 10 is formed between the first sub-abutting portion 2613 and the fixing portion 262. When the electronic device 100 is completely unfolded after the unfolding operation, part or all of the holder sidewall 12 of the hinge holder 10 is located in the receding space 264 and abuts against the first sub-abutting portion 2613. So as to play a role of limiting, and prevent the electronic device 100 from being damaged due to an excessively large unfolding angle of the electronic device 100 during the unfolding operation, for example, the display module 200 is damaged due to over-stretching.

In an embodiment, an abdicating groove 2614 is disposed on one side of the first sub-abutting portion 2613 facing the display module 200 to abdicate the first supporting plate 30 or the second supporting plate 40. In an embodiment, the relief groove 2614 may be omitted.

The fixing portion 262 may be made of a hard material. The surface of the fixing portion 262 close to the display module 200 is a plane for abutting against the display module 200 to support the display module 200.

The fixing portion 262 is provided with a fixing hole 2621 for passing through the rotating shaft portion 263, so as to fix the fixing portion 262 and the rotating shaft portion 263. A plurality of first limiting protrusions 2622 are uniformly distributed on the edge of the fixing portion 262 at the fixing hole 2621 and on the circumference of the side facing the first mounting base 251, so that the plurality of first limiting protrusions 2622 and the fixing portion 262 form a smooth curved surface facing the first mounting base 251 to cooperate with the damping assembly 29. In one embodiment, the fixing portion 262 may be integrated with the sliding portion 261.

The shaft portion 263 may be made of a hard material. One of the opposite ends of the rotating shaft portion 263 is located in a pivot hole 2514 of the first mounting base 251 to be rotatably connected with the first mounting base 251 and rotate around the first rotating shaft, and the other end is located in a second pivot hole 2562 of the second mounting base 252 to be rotatably connected with the second mounting base 252 and rotate around the first rotating shaft.

The rotation shaft portion 263 is provided with a sub-card fixing portion 2631 towards the end of the second mounting base 252, so that the sub-card fixing portion 2631 can enter the second pivot hole 2562 from the opening 2563, and can be fixedly clamped with the card of the second mounting base 252 on the axis of the rotation shaft portion 263, thereby preventing the rotation shaft portion 263 from being separated from the rotation connection with the second mounting base 252 on the axis of the rotation shaft portion 263.

In an embodiment, the rotating shaft portion 263 can be directly connected and fixed with the first mounting base 251 and the second mounting base 251, and the rotating shaft portion 263 penetrates through the fixing hole 2621 and is rotatably connected with the fixing portion 262.

In one embodiment, a plurality of first limiting protrusions 2622 are disposed on the rotating shaft portion 263 to form a smooth curved surface.

Referring to fig. 10 again, when the rotating shaft portion 263 is mounted on the second mounting base 252, the rotating shaft portion 263 of the first rotating arm 26 needs to be pushed from one opening 2563 to one second pivot hole 2562, and the rotating shaft portion 263 of the second rotating arm 27 needs to be pushed from the other opening 2563 to the other second pivot hole 2562, so that the rotating shaft portion 263 can be prevented from being disconnected from the second mounting base 252 in the axial direction due to the arrangement of the sub-fastening portion 2631. Then, the two openings 2543 of the fastener 254 correspond to the two rotating shaft portions 263 one by one, and the fastener 254 is slid, so that the rotating shaft portion 263 of the first rotating arm 26 is pushed from one opening 2543 to one second pivot hole 2542, and the rotating shaft portion 263 of the second rotating arm 27 is pushed from the other opening 2543 to the other second pivot hole 2542. Since the extending direction of the opening 2543 and the extending direction of the opening 2563 are alternately arranged to form a spatial interference, the first rotating arm 26 or the second rotating arm 27 is prevented from being simultaneously separated from the second pivoting hole 2542 and the second pivoting hole 2562 from the one opening 2543 and the one opening 2563. The function of reinforcing the fixed rotating shaft part 263 and the function of conveniently disassembling the rotating shaft part 263 are achieved.

The rotating shaft portion 263 is provided with a sub-transmission portion 2632 between the fixing portion 262 and the sub-card fixing portion 2631 so as to cooperate with the synchronous transmission component 28. In one embodiment, the sub-transmission portion 2632 may be a gear.

In one embodiment, the rotating shaft portion 263 and the fixing portion 262 are integrated. In one embodiment, the fixing portion 262 can be omitted, and the rotating shaft portion 263 is directly connected to the first sub-contacting portion 2613.

Referring again to fig. 10, the synchronous drive assembly 28 may include a support seat 281 disposed opposite the second mounting base 252 and disposed on the first and second

rotating arms

26 and 27, and a gear set 282 mounted on the second mounting base 252 and the support seat 281.

The supporting base 281 may be made of a hard material. The support seat 281 may include a support seat main body 2811 abutting against the fixing portion 262 of the first rotating arm 26 and the fixing portion 262 of the second rotating arm 27, respectively. The support seat body 2811 is located between the fixing portion 262 and the second mounting base 252. The support seat body 2811 is provided with a plurality of first through holes 2812 and a plurality of second through holes 2813. The first through holes 2812 correspond to the first pivot holes 2561 of the susceptor 253 one by one. Correspondingly, a first through hole 2812 and a first pivot hole 2561 are coaxially disposed, so that the gear set 282 is installed through the first through holes 2812 and the first pivot holes 2561. The second through holes 2813 correspond to the second pivot holes 2562 of the susceptor 253 one by one. A second through hole 2813 and a second pivot hole 2562 are coaxially formed, respectively, so as to mount the support base 281 on the first rotating arm 26 and the second rotating arm 27, and further indirectly on the second mounting base 252.

The support seat body 2811 is provided with a support portion 2814 extending towards one side of the first mounting base 251 near the middle of the edge of the display module 200. The supporting portion 2814 is located between the fixing portion 262 of the first rotating arm 26 and the fixing portion 262 of the second rotating arm 27, so as to shield a gap between the second rotating arm 27, such as the fixing portion 262, and the second rotating arm 27, such as the fixing portion 262, so as to abut against the display module 200 to support the display module 200.

In an embodiment, the supporting seat 281 may not be rotatably connected to the first rotating arm 26 and the second rotating arm 27, and the supporting seat 281 may be fixedly connected to the second mounting base 252, such as the sub-base 253. Of course, the supporting seat 281 may be integrated with the second mounting base 252, such as the sub-base 253. In an embodiment, the supporting seat 281 may not be connected to the first rotating arm 26 and the second rotating arm 27, and the supporting seat 281 may be connected and fixed to the second mounting base 252, such as the fastener 254. Of course, the supporting seat 281 may be integrated with the second mounting base 252, such as the fastener 254.

Referring to FIG. 10, gear set 282 may include an even number of gears that sequentially intermesh. The sub-transmission parts 2632 of the first rotating arms 26, the even number of gears, and the sub-transmission parts 2632 of the second rotating arms 27 are sequentially engaged with each other. A first pivot hole 2561, a first pivot hole 2541 and a first through hole 2812 are correspondingly used for fixing a gear. One end of the gear rotating shaft sequentially passes through a first pivot hole 2541 and a first pivot hole 2561 to be rotatably connected with the second mounting base 252, such as the sub-base 253. The other end of the gear rotation shaft passes through a first through hole 2812 and is rotatably connected to a support seat 281, for example, a support seat main body 2811. In one embodiment, the gear set 282 may be two gears engaged with each other, wherein one gear is engaged with the sub-transmission portion 2632 of the first rotating arm 26, and the other gear is engaged with the sub-transmission portion 2632 of the second rotating arm 27.

The even number of gears may be designed to make the first rotating arm 26 rotate in a forward direction, so that the second rotating arm 27 simultaneously rotates in a reverse direction, and the first rotating arm 26 and the second rotating arm 27 rotate synchronously. So as to prevent one of the first rotating arm 26 and the second rotating arm 27 from rotating, the other rotating arm does not rotate, or the rotating amplitude of one rotating arm is different from that of the other rotating arm, thereby protecting the display module 200.

It can be understood that the gears of the gear set 282 disposed in the corresponding

first pivot holes

2561 and 2541 can fix the fastener 254, so as to prevent the fastener 254 from shifting, and further prevent the first rotating arm 26 and the second rotating arm 27 from being separated from the rotational connection with the second mounting base 252.

In one embodiment, the synchronizing drive assembly 28 may be omitted.

Referring to fig. 16, a schematic diagram of a portion of the adjusting assembly 21 in the embodiment of fig. 10 of the present application is disclosed. The supporting portion 2814 shields the sub-transmission portion 2632 and the gear set 282, so as to prevent the gear set 282 and the sub-transmission portion 2632 from being exposed, and prevent the display module 200 from directly contacting the sub-transmission portion 2632 and the gear set 282. The problem that the display module 200 is damaged by pressing by the user due to the fact that the display module 200 cannot be supported at the positions of the sub-transmission portion 2632 and the gear set 282 is also solved.

The surface of the support portion 2814 supporting the display module 200 is flush with the surface of the connecting portion 256 and the surface of the support portion 257 supporting the display module 200.

Referring to fig. 10 again, the damping assembly 29 may include an elastic member 291 for providing a pressing force, and a limiting member 292 which is applied by the elastic member 291 and limits the first rotating arm 26 and the second rotating arm 27 under the application of a pressing force. The elastic element 291 extrudes the limiting element 292, so that the static friction between the limiting element 292 and the contact surfaces of the first rotating arm 26 and the second rotating arm 27 is improved, and the electronic device 100 has a better damping effect during the folding process, thereby improving the use hand feeling of a user.

The elastic member 291 is made of an elastic material. Here, taking the elastic element 291 as a spring as an example, one spring is sleeved on each of the rotating shaft portion 263 of the first rotating arm 26 and the rotating shaft portion 263 of the second rotating arm 27, one end of each spring abuts against the first mounting base 251, such as the connecting lug 2513, and the other end abuts against the limiting element 292.

In one embodiment, the elastic element 291 may be a spring, and may be sleeved on the rotating shaft 263 of the first rotating arm 26 or the rotating shaft 263 of the second rotating arm 27.

When the rotating arm rotates, the connecting arm also rotates, and the second rotating shaft of the rotating shaft assembly 22 rotating around the first sub-pivot portion 2564 is parallel to the axis of the second pivot hole 2562 (i.e. the first rotating shaft), and is closer to the display module 200 than the axis of the second pivot hole 2562. Therefore, the movement tracks of the rotating arm and the connecting arm are different, the connecting seat rotates along with the rotating arm and rotates under the limitation of the length of the connecting arm, and then the sliding part 261 and the guide part 232 of the rotating arm slide relatively in order to make up for the difference of the axis positions of the rotating arm. Meanwhile, the connecting base and the connecting arm rotate around the rotating connecting portion 233 and the connecting portion 2222, so that the posture of the connecting base is matched with the rotating arm, and the rotating arm and the connecting base cannot slide relatively.

In one embodiment, the protrusion 311 may be omitted.

The pivot 32 may include a first sub-pivot 321 rotatably connected to the shaft 22, such as a connecting arm, and a second sub-pivot 322 coupled to the first sub-pivot 321 and rotatably connected to the connecting base.

It is understood that the names of the "first sub-pivoting portion", "second sub-pivoting portion", "third sub-pivoting portion", and "pivoting portion" may be interchanged in some embodiments. For example, in one embodiment, the "first sub-hinge" in other embodiments is referred to as the "second sub-hinge", and correspondingly, the "second sub-hinge" in other embodiments is referred to as the "first sub-hinge".

The pivoting member body 3211 protrudes out of the second sub-abutting portion 3214, and the second sub-abutting portion 3214 is configured to abut against the supporting frame sidewall 12 of the supporting frame 10.

The fourth sub-pivot portion 3212 is provided with an arc-shaped groove so that the connecting seat, for example, the third sub-pivot portion 2312, can slide in the arc-shaped groove. The rotating connection between the supporting plate body 31 and the connecting seat is realized.

Referring to fig. 26, a schematic structural diagram illustrating the connection between the first sub-pivot 321 and the connecting arm in the embodiment of fig. 25 is disclosed. The abdicating slide rail 3213 is provided with an arc-shaped slide way 3215, so that the rotating shaft assembly 22, for example, the connecting portion 2222, can slide in the arc-shaped slide way 3215, so as to abdicate the display module assembly 200 when the electronic device 100 is folded.

Please refer to fig. 25 again. The second sub-pivot 322 has a fourth sub-pivot 3221 disposed thereon for connecting with the connecting seat. The fourth sub-pivot portion 3221 is an arc-shaped groove. So that the connecting seat such as the third sub-pivoting portion 2312 is placed in the circular arc groove to slide along the extending direction of the circular arc groove and the extending direction of the slider.

Referring to fig. 27 and 28, fig. 27 is a schematic structural diagram illustrating the folding mechanism 800 and the display module 200 of the embodiment of the present application shown in fig. 1 after being completely unfolded, and fig. 28 is a schematic structural diagram illustrating the folding mechanism 800 and the display module 200 of the embodiment of the present application shown in fig. 1 after being completely unfolded. When the electronic device 100 is completely unfolded, the first supporting plate 30 and the second supporting plate 40 support the display module 200, so that the display module 200 tends to be flat.

When the electronic device 100 is folded, the first connecting seat 23 and the second connecting seat 24 are stressed, so that when the electronic device 100 is folded towards one side of the display module 200, because the first rotating arm 26 and the first connecting seat 23 are slidably connected, the second rotating arm 27 and the second connecting seat 24 are slidably connected, and further the first rotating arm 26 and the second rotating arm 27 are folded towards one side of the display module 200, because a second rotating shaft for rotating the first connecting arm 222 and the second connecting arm 223 is different from a first rotating shaft for rotating the first rotating arm 26 and the second rotating arm 27, when the first connecting seat 23 and the first rotating arm 26 rotate together, the first connecting seat 23 is limited by the rotation of the first connecting seat 23 with the radius of the first connecting arm 222, and the first rotating arm 26 slides with the first connecting seat 23 in order to compensate for the difference of the rotating axes, during the sliding process, the first supporting plate 30 is pulled, so that the first supporting plate 30 rotates with the first connecting seat 23, and further, the first supporting plate 30 drives the display module 200 to move towards one side far from the display module 200 at one side far from the first connecting seat 23. Meanwhile, when the second connecting seat 24 and the second rotating arm 27 rotate together, the second connecting seat 24 is limited by the rotation of the second connecting seat 24 with the radius of the first connecting arm 223, and the second rotating arm 27 slides with the second connecting seat 24 in order to compensate for the difference of the rotation axes, during the sliding process, the second supporting plate 40 is pulled, so that the second supporting plate 40 rotates with the second connecting seat 24, and further, one side of the second supporting plate 40 far away from the first connecting seat 23 drives the display module 200 to move towards one side far away from the display module 200. Under the movement of the first supporting plate 30 and the second supporting plate 40, as shown in fig. 28, a droplet-shaped space is formed at the folding position of the display module 200, so as to prevent the display module 200 from being folded to form traces. In addition, the space between the portion of the first housing 400 and the portion of the second housing 600 of the folded display module 200 can be minimized, and even the folded electronic device 100 can be thinner.

When the electronic device 100 is unfolded, the first connecting seat 23 and the second connecting seat 24 are stressed to unfold the electronic device 100 toward the side away from the display module 200.

It is understood that the names of "first pivot hole", "second pivot hole", "first through hole", "second through hole", "through hole" and "through hole" may be interchanged in some embodiments. For example, in one embodiment, the "first pivot hole" in other embodiments is referred to as the "second pivot hole", and correspondingly, the "second pivot hole" in other embodiments is referred to as the "first pivot hole".

It can be understood that, when the electronic device 100 performs the folding or unfolding operation, the first rotating arm 26 and the first connecting seat 23 are relatively stationary and rotate together around the first fixed base 25, and only slide with the first connecting seat 23 under the limitation of the distance between the first connecting seat 23 and the second rotating axis of the first connecting arm 222, the second rotating arm 27 and the second connecting seat 24 are relatively stationary and rotate with the second fixed base 221, and only slide with the second connecting seat 24 under the limitation of the distance between the second connecting seat 24 and the second rotating axis of the second connecting arm 223.
