Compared with traditional display devices, the flexible screens have advantages of foldability and flexibility, and are widely favored by consumers. Because the flexible screen is relatively fragile and easily damaged when subjected to a large tensile force, therefore, how to design a compensation structure to reduce or avoid the flexible screen from being damaged has becomes a problem that the industry has always sought to solve.
- The present disclosure provides an electronic device capable of preventing flexible members (including flexible screens, flexible sensors, etc.) from being easily damaged.
- The present disclosure provides an electronic device, which includes a first frame, a second frame, a bendable hinge located between the first frame and the second frame, and a flexible member covering the first frame, the second frame and the bendable hinge. The electronic device further includes a sliding member located on one side of the bendable hinge, and a supporting member connecting the sliding member and the first frame; the flexible member connects the first frame and the second frame; when the bendable hinge is bent, the supporting member drives the sliding member to slide relative to the bendable hinge, and the flexible member drives the second frame to slide relative to the bendable hinge.
- The flexible member of the rotating mechanism of the electronic device of the present disclosure connects the first frame and the second frame, and covers the first frame, the second frame and the bendable hinge located between the first frame and the second frame. When the bendable hinge is bent, the flexible member can drive the second frame to slide relative to the bendable hinge which reduces a tensile force subjected by the flexible member during bending, thereby reducing or avoiding damage to the flexible member.

Thehinge body 25 includes a plurality of hinge units and acompensation mechanism 253. The plurality of hinge units are connected to thecompensation mechanism 253. The plurality of hinge units can rotate relatively to achieve bending or unfolding of thehinge body 25, such that thecompensation mechanism 23 can perform compensation movement. When the bendable hinge is bent, theflexible member 30 can drive thesecond frame 23 to slide relative to thebendable assembly 24 or thehinge body 25, reducing a stretching force that theflexible member 20 is subjected to when bending, thereby reducing or avoiding the damage of theflexible member 30. - Alternatively, the
bendable assembly 24 can be a bendable hinge. The bendable hinge may include a plurality of hinge units, or may include a plurality of hinge units and at least one connecting member located on one side of the plurality of hinge units, or may include a plurality of hinge units and a compensation mechanism located on at least one side of the plurality of hinge units. Alternatively, the connecting member can be regarded as a hinge unit. Alternatively, the compensation mechanism can also be regarded as a hinge unit.

In this embodiment, the supportingmember 50 covers a front surface of thecompensation mechanism 253, a front surface of thehinge body 25, and a front surface of thefirst frame 21. Theflexible member 30 is a flexible screen, and a back surface of the flexible screen is attached to a front surface of the supportingmember 50 and a front surface of thesecond frame 23. The flexible screen may be a flexible display screen or a flexible touch screen, or a combination of both. The same ends of thecentral hinge 250, the two supportinghinges 251, the connectinghinge 252 and thecompensation mechanism 253 are rotatably connected to one body through thehinge mechanism 60, that is, opposite sides of thecentral hinge 250 are rotatably connected to the two supportinghinges 251, one side of one supportinghinge 251 away from thecentral hinge 250 is rotatably connected to the connectinghinge 252, and one side of the other supportinghinge 251 away from thecentral hinge 250 is rotatably connected to thecompensation mechanism 253.

One end of the otherfirst linking member 266 away from thecentral hinge 250 is slidably connected to or abuts against the connectinghinge 252. The connectinghinge 252 and thecompensation mechanism 253 both rotate relative to thecentral hinge 250, so as to drive the corresponding first linkingmember 266 and the corresponding supportinghinge 251 to rotate, which causes thehinge body 25 to be bent or unfolded, so as to achieve a bending or an unfolding of theflexible member 30. Alternatively, the sliding member includes a mountingframe 254, and the connectingmember 255 is slidably connected to the mountingframe 254. Thesecond frame 23 and the sliding member are slidably connected in parallel to thefirst frame 21 or the bendable hinge.

hinge 252 and thecompensation mechanism 253 rotate toward one side away from a light emitting surface of theflexible member 30, the corresponding first linkingmember 266 and the corresponding supportinghinge 251 are caused to rotate towards one side away from the light emitting surface of theflexible member 30, and thebendable assembly 24 is thus bent, thereby thebendable region 31 of theflexible member 30 is realized to be bent. When the connectinghinge 252 and thecompensation mechanism 253 rotate towards the light emitting surface of theflexible member 30, the corresponding first linkingmember 266 and the corresponding supportinghinge 251 are caused to rotate towards the light emitting surface of theflexible member 30, and thebendable assembly 24 is thus unfolded, thereby thebendable region 31 of theflexible member 30 is realized to be unfolded. - In this embodiment, the number of the rotating
mechanisms 26 is two. The tworotating mechanisms 26 are respectively disposed at opposite ends of thehinge body 25. The number of thecentral hinge 250 is one.

When the twofirst linking members 266 of therotating mechanism 26 rotate towards one side by following the connectinghinge 252 andcompensation mechanism 253 respectively, the two supportinghinges 251 also rotate to the same side, so as to bend and unfold thebendable assembly 24, so that thebendable assembly 24 can adapt to the bending requirements of theflexible member 30. In addition, thecompensation mechanism 253 is only disposed on one side of thehinge body 25, and thecompensation mechanism 253 is configured as one of the hinge units of thehinge body 25, so that thecompensation mechanism 253 occupies less stacking space of the whole machine, which is beneficial to expand the internal space of the whole machine and can accommodate a larger capacity battery, other electronic components with larger sizes or more electronic components, and can further save the plurality of components of thecompensation mechanism 253, reducing manufacturing costs. - In this embodiment, the supporting
member 50 is a thin steel sheet that can be bent. Preferably, the supportingmember 50 is a liquid metal sheet. The reason why the liquid metal sheet is selected as the supportingmember 50 is that the liquid metal sheet has better abrasion resistance. - In other embodiments, the supporting
member 50 may also be a soft wear-resistant plastic sheet, a Teflon coating, a soft wear-resistant rubber sheet, a soft silicone sheet, or so on. - As shown in
FIGS. 2 and 3 , the supportingmember 50 defines a plurality of connectinggrooves 52 corresponding to the front surface of thehinge body 25.

The two opposite ends of one side of thesecond frame 23 close to the receivingslot 210 are respectively provided with a connectingmember 230. One side of the connectingmember 230 facing the receivingslot 210 interconnects with the receivingslot 210. One edge of thesecond frame 23 and the connectingmember 230 cooperatively form asecond receiving space 232 having a “” shape.

Specifically, the tworotating mechanisms 26 are placed on the two mountingportions 2503 of thecentral hinge 250 respectively, so that thepositioning post 2506 of each mountingportion 2503 is engaged with the engaginghole 2684 of the connectingmember 268 of the correspondingrotating mechanism 26; the clamping blocks 2508 at opposite ends of thecentral hinge 250 are snapped to the first hinges 61 of the twohinge mechanism 60, respectively; the throughhole 2685 of the connectingblock 2681, the throughhole 2686 of the connectingpiece 2683, the throughhole 618 of the connectingbar 613 and the throughhole 616 of the connectingpiece 615 respectively face the fixingholes 2507 of thecentral hinge 250; several locking members are inserted into the throughholes holes 2507 to install tworotating mechanisms 26 and twohinge mechanisms 60 at opposite ends of thecentral hinge 250. - The two supporting
hinges 251 are placed on opposite sides of thecentral hinge 250 respectively, so that the two slidingguides 2516 of each supportinghinge 251 can be slidably inserted into theguide grooves 2687 corresponding to the two rotatingmechanisms 26. The two opposite ends of each supportinghinge 251 are respectively connected to the second hinges 63 corresponding to the twohinge mechanisms 60, that is, the connectingbars 633 of thesecond hinge members 63 of eachhinge mechanism 60 are inserted into the corresponding clampinggrooves 2517 of the corresponding supportinghinge 251; the throughhole 635 of each connectingbar 633 faces thefixing hole 2518 corresponding to the supportinghinge 251, and a plurality of locking members are inserted into the throughhole 635 and locked in thecorresponding fixing hole 2518, so that the two supportinghinge 251 are rotatably connected to the twohinge mechanisms 60 relative to thecentral hinge 26 between. At this time, theguide slide 2516 of each supportinghinge 251 is slidably inserted into thecorresponding guide groove 2687. - The connecting
hinge 252 is placed on one side of thesecond linking member 267 away from the supportinghinge 251. The two first linkingmembers 266 on the same side are slidably inserted into the twofirst guide grooves 2527 of the connectinghinge 252, respectively. The twoprojections 2511 of the supportinghinge 251 are respectively facing the two insertingholes 2523 of the connectinghinge 252, the twoavoidance holes 25110 of the supportinghinge 251 corresponding to the two extendingblocks 2525 of the connectinghinge 252, and the opposite ends of the connectinghinge 252 abuts against the third hinges 65 corresponding to the twohinge mechanisms 60, that is, the connectingpieces 653 of the third hinges 65 on the same side of eachhinge mechanism 60 are respectively inserted into the clampinggrooves 2521 corresponding to the connectinghinge 252; the throughhole 655 of each connectingpiece 653 faces thefixing hole 2522 corresponding to the connectinghinge 252, and a plurality of locking members each each is inserted into the throughhole 655 and locked in thecorresponding fixing hole 2522. At this time, the twoprojections 2511 of the supportinghinge 251 are slidably inserted into the corresponding two insertingholes 2523, and the two extendingblocks 2525 of the connectinghinge 252 are slidably inserted into the corresponding avoidance holes 25110. - The
compensation mechanism 253 is placed on one side of the supportinghinge 251 close to thesecond linking member 267. The two first linkingmembers 266 and the twosecond linking members 267 on the same side are slidably inserted into the twofirst guide grooves 2527 and twosecond guide grooves 2578 of thecompensation mechanism 253, respectively. The connectingposts 2675 of eachsecond linking member 267 are rotatably inserted into the correspondingrotating holes 2587, respectively. Theabutting block 2564 abuts the side of thefirst linking member 266 and is configured to apply a damping force to thefirst linking member 266 under the elastic force of theelastic member 2560. Specifically, the abuttingblock 2564 abuts the side surface of thefirst linking member 266 along a sliding direction perpendicular to thefirst linking member 266. When thebendable assembly 24 is bent, thefirst linking member 266 slides relative to the connectingmember 257 in the axial direction perpendicular to the connectingshaft 261, and theabutting block 2564 elastically resists thefirst linking member 266 so as to generate a friction force to thefirst linking member 266. Thebendable assembly 24 has a certain damping during the bending process, which improves the bending feel of the whole machine. The twoprojections 2511 of the supportinghinge 251 are respectively opposite to the two inserting holes of thecompensation mechanism 253, the two extendingblocks 2569 of thecompensation mechanism 253 respectively correspond to the twoavoidance holes 25110 of the supportinghinge 251, and the opposite ends of thecompensation mechanism 253 abut against the corresponding third hinges 65 of thehinge mechanism 60, that is, the third hinges 65 on the same side of thehinge mechanism 60 are respectively inserted into the clamping grooves corresponding to thecompensation mechanism 25, and the throughhole 655 of each connectingpiece 653 faces thefixing hole 2574 corresponding to thecompensation mechanism 253, and a plurality of locking members are inserted into the throughholes 655 and locked into the corresponding fixing holes 2574. At this time, the twoprotrusions 2511 of the supportinghinge 251 are slidably inserted into the two inserting holes corresponding to thecompensation mechanism 25, and the two extendingblocks 2569 of thecompensation mechanism 25 are slidably inserted into the corresponding avoidance holes 25110. The two connectingpieces 259 are covered on the back surface of the two slidingplates 258. The ends of the connectingposts 2675 are slidably received in theguide grooves 2591. The connecting member inserted into the connectinghole 2585 of the slidingplate 258 and the corresponding strip-shapedgroove 2588 of thepositioning piece 2586 is facing the receivinghole 2593 of the connectingpiece 259. A plurality of locking members are respectively connected to the corresponding connectingmembers 257 through the throughholes 2595 of the connectingpiece 259. Alternatively, a diameter of the receivinghole 2593 is larger than a diameter of the connecting member inserted into the connecting hole of the sliding plate, so that the connecting member can freely slide within the receiving hole. - At this time, as shown in
FIG. 18 , twoopposite hinge mechanisms 60 articulate the connectinghinge 252,compensation mechanism 253, two supportinghinges 251, andcentral hinge 250 in one body. Specifically, the connectinghinge 252 and thecompensation mechanism 253 are respectively hinged with the corresponding two supporting hinges 251. The two supportinghinges 251 are hinged between the opposite sides of the connectinghinge 252 and thecompensation mechanism 253 and the opposite sides of thecentral hinge 250 respectively. - Please referring to
FIG. 1 toFIG. 5 together, the installedbendable assembly 24 is placed in the receivingslot 210 between thefirst frame 21 and thesecond frame 23, so that the twolugs 2575 of thecompensation mechanism 253 are respectively received in the connectingmembers 230 of thesecond frame 23, the throughholes 2581 of each slidingplate 258 respectively correspond to the mountingholes 235 of the mountingbar 234; a plurality of locking members are inserted into the throughholes 2581 of the slidingplate 258 and locked in the corresponding mountingholes 235, so that the two slidingplates 258 are fixedly connected to thesecond frame 23 respectively. The secondelastic members 2570 are located between the connectingmember 255 and thesecond frame 23, the connectingmember 255 can slide relative to the slidingplate 258, and the connectinghinge 252 is fixedly connected to thefirst frame 21. The supportingmember 50 is covered on the front surface of thebendable assembly 24 and the front surface of thefirst frame 21. One side of the supportingmember 50 is fixed to thefirst frame 21, and the other side of the supportingmember 50 is fixed to the mountingframe 254. The bendable hinge or the connecting member of the bendable hinge can slide relative to the mountingframe 254. Alternatively, the firstelastic members 2560 may be pre-compressed between the mountingframe 254 and the connectingmember 230. The corresponding connectingports 2505 on thecentral hinge 250 and the corresponding connectingports 2515 on the adjacent supportinghinge 251 are connected to the supportingmember 50 by colloid. Specifically, the colloid is separately dispensed into the dispensingports 2504 of thecentral hinge 250 and the dispensingports 2514 of the supportinghinge 251 through a dispensing device. The colloid in each dispensingport 2504 is filled into the corresponding connectingport 2515 to be connected with the back surface of the supportingmember 50 so that the supportingmember 50 and thebendable assembly 24 are connected. The supportingmember 50 is fixedly connected to the front surface of thefirst frame 21. The back surfaces of the twonon-bendable regions 33 of theflexible member 30 are respectively fixed to the supportingmember 50 and thesecond frame 23 above thefirst frame 21, and the back surfaces of thebendable region 31 of theflexible member 30 are slidably covered to another part of the supportingmember 50 above thebendable assembly 24. Alternatively, the secondelastic members 2570 may be pre-compressed between thecompensation mechanism 253 and thesecond frame 23. The colloid of the connectinggroove 52 of the supportingmember 50 is adhered to the back surface of thebendable region 31 of theflexible member 30. At this time, the back surface of theflexible member 30 is fixed on thefirst frame 21 and thesecond frame 23, thebendable region 31 offlexible member 30 can be bent as thebendable assembly 24 bends. Thecompensation mechanism 253 pushes theflexible member 30 away from thebendable assembly 24, so that theflexible member 30 has been a stretched state, which preventsflexible member 30 from arching and being damaged. When theflexible member 30 is in an unfolded state, one of the side surfaces 2589 of eachpositioning piece 2586 is positioned and attached to the correspondingfirst positioning surface 2579 to keep thebendable assembly 24 in the unfolded state. - Please referring to
FIG. 23 toFIG. 27 together, when theelectronic device 100 is bent, the bending force is applied to thefirst frame 21 and thesecond frame 23 ofelectronic device 100, so that the connectinghinge 252 and thecompensation mechanism 253 connected to thefirst frame 21 and thesecond frame 23 are rotating towards a direction adjacent to each other. The rotating mechanism realizes the bending of thebendable assembly 24. Specifically, the bending force is applied to thefirst frame 21 and thesecond frame 23 together, thefirst frame 21 drives the connectinghinge 252 and thesecond frame 23 drives thecompensation mechanism 253 to rotate toward one side away from theflexible member 30 relative to the supportinghinge 251. The twoprotrusions 2511 of one supportinghinge 251 are slidably inserted into the two insertingholes 2523 of the connectinghinge 252. The two extendingblocks 2525 of the connectinghinge 252 are slidably inserted into the avoidance holes 25110 of one supportinghinge 251. One supportinghinge 251 rotates toward one side away from theflexible member 30 relative to thecentral hinge 250. Theguide slide 2516 of one supportinghinge 251 is slidably inserted into thecorresponding guide groove 2687. The twoprojections 2511 of the other supportinghinge 251 are slidably inserted into the two inserting holes of thecompensation mechanism 253. The two extendingblocks 2569 of thecompensation mechanism 253 are slidably inserted into the avoidance holes 25110 of the other supportinghinge 251. The other supportinghinge 251 rotates toward one side away from theflexible member 30 relative to thecentral hinge 250. Theguide slide 2516 of the other supportinghinge 251 is slidably inserted into thecorresponding guide groove 2687. At the same time, the connectinghinge 252 and thecompensation mechanism 253 drive thefirst linking member 266 and thesecond linking member 267 corresponding to the tworotating mechanisms 26 to rotate, so that thefirst linking member 266 slides along the correspondingfirst guide grooves second linking member 267 slides along the correspondingsecond guide groove 2578. tThe second linkingmember 267 slidably pushes against thepositioning piece 2586 to rotate thepositioning piece 2586 so as to disengage from thefirst positioning surface 2579. The end of thesecond linking member 267 and the opposite sidse of the slidingplate 258 gradually approach from the separation until they resist, to position thebendable assembly 24 in a bent state. Thebendable region 31 of theflexible member 30 bends along with thebendable assembly 24 until the back surfaces of thefirst frame 21 and thesecond frame 23 are attached. When thebendable assembly 24 is unfolded again, the ends of thesecond linking member 267 are gradually separated from the side surface of the slidingplate 258, and the side surfaces of thepositioning piece 2586 gradually approach thefirst positioning surface 2579 from the separated state until they are mutually opposed hold. Since the side surface of thepositioning piece 2586 in the unfolded state abuts thefirst positioning surface 2579, the end of thesecond linking member 267 in the folded state abuts the side surface of theslide plate 258, so that thesecond frame 23 is limited in the unfolded state or in the bent state, reducing or avoiding the collapse caused by side impact (such as falling). Of course, in other embodiments, thesecond frame 23 may be limited only in the bent state or the unfolded state, and the corresponding structure may also be simplified. - Alternatively, during the bending process, the mounting
frame 254 slides relative to the bendable hinge, and thesecond frame 23 slides relative to the bendable hinge. Alternatively, the mountingframe 254 slides in the direction of thefirst frame 21 or the bendable hinge relative to the bendable hinge, and thesecond frame 23 slides in the direction of thefirst frame 21 or the bendable hinge relative to the bendable hinge. Alternatively, a sliding distance of thesecond frame 23 relative to the bendable hinge is greater than that of the mountingframe 254 relative to the bendable hinge. Alternatively, the second frame slides relative to the hinge unit of the bendable hinge close to the second frame. The mounting frame slides relative to the hinge unit of the bendable hinge close the mounting frame. Alternatively, the second frame slides relative to the connecting member of the bendable hinge. The mounting frame slides relative to the connecting member of the bendable hinge. Alternatively, a sliding distance of the second frame relative to the connecting member of the bendable hinge is greater than that of the mounting frame relative to the connecting member of the bendable hinge. In the unfolding process, the mountingframe 254 slides relative to the bendable hinge, and thesecond frame 23 slides relative to the bendable hinge. Alternatively, the mountingframe 254 slides relative to the direction of the bendable hinge away from thefirst frame 21 or the direction of the bendable hinge, and thesecond frame 23 slides relative to the direction of the bendable hinge away from thefirst frame 21 or the direction of the bendable hinge. Alternatively, a sliding distance of thesecond frame 23 relative to the bendable hinge is greater than that of the mountingframe 254 relative to the bendable hinge. Alternatively, the second frame slides relative to the hinge unit of the bendable hinge close to the second frame. The mounting frame slides relative to the hinge unit of the bendable hinge close to the mounting frame. Alternatively, the second frame slides relative to the connecting member of the bendable hinge. The mounting frame slides relative to the connecting member of the bendable hinge. Alternatively, a sliding distance of the second frame relative to the connecting member of the bendable hinge is greater than a sliding distance of the mounting frame relative to the connecting member of the bendable hinge. - Alternatively, the
second frame 23 and the mountingframe 254 slide in parallel with the bendable hinge. That is, the sliding of thesecond frame 23 relative to the bendable hinge does not depend on the mountingframe 254, and the sliding of the mountingframe 254 relative to the bendable hinge does not depend on thesecond frame 23. Alternatively, thesecond frame 23 and the mountingframe 254 are slid in parallel with the bendable hinge through respectiveelastic members 2563. - At this time, the
bendable assembly 24 is bent, and theflexible member 30 bends along withbendable assembly 24, so that the upper surface of connectinghinge 252, the upper surface of supportinghinge 251, the upper surface of thecentral hinge 250, and the upper surface of thecompensation mechanism 253 are connected to each other to form an arched arc, in order to facilitate fitting the supportingmember 50. During the bending of theelectronic device 100, the firstelastic member 2560 is further compressed against thepressing piece 2542 of the mountingframe 254, and the secondelastic member 2570 is further compressed against. - The first
elastic members 2560 and the secondelastic members 2570 are compressed when the bendable hinge is expanded and bent. The firstelastic member 2560 is less compressed when the bendable hinge is expanded than the firstelastic member 2560 is compressed when the bendable hinge is bent; the secondelastic member 2570 is less compressed when the bendable hinge is expanded than the secondelastic member 2570 is compressed when the bendable hinge is bent. When the bendable hinge is bent, the compression amount of the secondelastic member 2570 is greater than that of the firstelastic member 2560. When the bendable hinge is bent, theflexible member 30 and the supportingmember 50 are relatively fixed at a position corresponding to thefirst frame 21, and relatively slide at a position corresponding to the bendable hinge. - The above is the implementation of the embodiments of the present disclosure. It should be noted that for those of ordinary skill in the art, several improvements and retouches can be made without departing from the principles of the embodiments of the present disclosure, and these improvements and retouches are also regarded as the protection scope of the present disclosure.
