Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] With the improvement of user demand and the development of technology, the screens of electronic devices are getting bigger and bigger. In order to take into account the large screen and the portability of electronic devices, electronic devices equipped with scroll screens are gradually favored by users. In order to adaptively support the flexible screen, the electronic devices involved in the related technology adopt two comb tooth structures that can move relatively. However, the comb tooth structure has the problem of weak strength and cannot support the flexible screen well.

[0003] In addition, the two comb-tooth structures that cooperate with each other will cause serious friction when the flexible screen is expanded or contracted, which will cause abnormal noise, which will undoubtedly affect the user's use. Summary of the invention

[0004] The present invention discloses an electronic device to solve the problem in the related art that when the electronic device uses two relatively movable comb-tooth structures to support a flexible screen, the comb-tooth structures have serious friction during the process of the flexible screen being unfolded or retracted, which in turn causes abnormal noise.

[0005] In order to solve the above-mentioned technical problems, the present invention is achieved as follows:

[0006] The present application discloses an electronic device, comprising a first body, a second body, a plurality of rotating supports and a flexible display screen, wherein the second body is movably arranged on the first body, the flexible display screen is arranged on the first body and the second body, and the plurality of rotating supports are rotatably arranged on the first body;

[0007] When the electronic device is in a folded state, the second body is stacked on the plurality of rotating supports, and the second body is used to support the flexible display screen, the second body is isolated between the plurality of rotating supports and the flexible display screen, and the rotating supports are separated from the flexible display screen;

[0008] When the electronic device is in the unfolded state, the second body is at least offset from the multiple rotating support members, and the multiple rotating support members rotate to a position where their edges are in linear contact with the flexible display screen, the edges of the multiple rotating support members and the second body jointly support the flexible display screen, and the rotating support members abut against the flexible display screen.

[0009] The technical solution adopted by the present invention can achieve the following technical effects:

[0010] The electronic device disclosed in the embodiment of the present application is provided with a plurality of rotating supports, so that the rotating supports are rotatably arranged on the first body, so that when the electronic device is in the unfolded state, the second body is at least misaligned with the plurality of supports, and the rotating supports can rotate to rotate its edges to a position in contact with the flexible display line, so that the edges of the rotating supports and the second body jointly support the flexible display, so that the flexible display is better supported. When the electronic device is switched to the folded state, the second body moves relative to the first body, the rotating supports rotate to separate from the flexible display, the second body is stacked on the plurality of rotating supports, and the second body is isolated between the plurality of rotating supports and the flexible display, and at this time the flexible display can be better supported by the second body.

[0011] The embodiment of the present application adopts the method of rotating the rotating support member relative to the first body so that the electronic device can be well supported in both the unfolded state and the folded state, thereby replacing the method of using two relatively movable comb-tooth structures to support the flexible display screen in the electronic device in the related art. Since the edge and the flexible display screen are in line contact, the problem that when the electronic device in the related art uses two relatively movable comb-tooth structures to support the flexible screen, the comb-tooth structure has relatively serious friction during the unfolding or contraction of the flexible screen, which in turn causes abnormal noise, can be solved. Moreover, the rotating support member supports the flexible display screen through the edge, so that the rotating support member has a higher strength when supporting the flexible display screen, thereby solving the problem that the electronic device in the related art uses a comb-tooth structure with weak strength.

[0057] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0059] Please refer to Figures 1 to 37 The embodiment of the present invention discloses an electronic device, which may be a mobile phone, a tablet, a game console, etc. The disclosed electronic device includes a first body 100, a second body 200, a plurality of rotating support members 300 and a flexible display screen 400.

[0060] The first body 100 and the second body 200 can be the base for installing other components of the electronic device, and the second body 200 is movably arranged on the first body 100. The flexible display screen 400 is arranged on the first body 100 and the second body 200, and the plurality of rotating support members 300 are rotatably arranged on the first body 100. The second body 200 can move relative to the first body 100 to switch the electronic device between a folded state and an unfolded state.

[0061] When the electronic device is in the folded state, the second body 200 is stacked on the plurality of rotating supports 300, and the second body 200 is used to support the flexible display screen 400. The second body 200 is isolated between the plurality of rotating supports 300 and the flexible display screen 400, and the rotating supports 300 are separated from the flexible display screen 400. Specifically, when the electronic device is in the folded state, the second body 200 can be stacked on the plurality of rotating supports 300 in a covering manner.

[0062] When the electronic device is in the unfolded state, the second body 200 is misaligned with at least a plurality of rotating supports 300, and the plurality of rotating supports 300 rotate to a position where their edges are in linear contact with the flexible display screen 400, and the edges of the plurality of rotating supports 300 and the second body 200 jointly support the flexible display screen 400, and the rotating supports abut against the flexible display screen 400.

[0063] Specifically, the second body 200 is misaligned with at least a plurality of rotating supports 300 , which may mean that, in the direction in which the rotating supports 300 point toward the flexible display screen 400 , the second body 200 only covers a portion of the rotating supports 300 or the second body 200 does not cover the rotating supports 300 at all, so as not to affect the rotation of the plurality of rotating supports 300 .

[0064] In a specific implementation process, when the electronic device is in the folded state, the second body 200 covers the multiple rotating supports 300, and the second body 200 is used to support the flexible display screen 400. The second body 200 is isolated between the multiple rotating supports 300 and the flexible display screen 400, and the rotating supports 300 are separated from the flexible display screen 400. When the electronic device switches from the folded state to the unfolded state, the second body 200 moves relative to the first body 100 so that the second body 200 is at least misaligned with the multiple rotating supports 300, and the multiple rotating supports 300 can be rotated to a position where their edges are in line contact with the flexible display screen 400, thereby reducing the contact area, and the rotating supports 300 abut against the flexible display screen 400, and the edges of the multiple rotating supports 300 and the second body 200 jointly support the flexible display screen 400. When the electronic device switches from the unfolded state to the folded state, the second body 200 moves relative to the first body 100, the rotating support member 300 rotates to separate from the flexible display screen 400, the second body 200 covers multiple rotating support members 300, and the second body 200 supports the flexible display screen 400, and the second body 200 is isolated between the multiple rotating support members 300 and the flexible display screen 400.

[0065] The electronic device disclosed in the embodiment of the present application is provided with a plurality of rotating support members 300, so that the rotating support members 300 are rotatably arranged on the first body 100, so that when the electronic device is in the unfolded state, the second body 200 is at least misaligned with the plurality of support members 300, and the rotating support member 300 can rotate to rotate its edge to a position of linear contact with the flexible display screen 400, so that the edge of the rotating support member 300 and the second body 200 jointly support the flexible display screen 400, so that the flexible display screen 400 is well supported. When the electronic device is switched to the folded state, the second body 200 moves relative to the first body 100, the rotating support member 300 rotates to separate from the flexible display screen 400, the second body 200 is stacked on the plurality of rotating support members 300, and the second body 200 is isolated between the plurality of rotating support members 300 and the flexible display screen 400, and at this time, the flexible display screen 400 can be well supported by the second body 200. The embodiment of the present application adopts the method of rotating the rotating support member 300 relative to the first body 100 so that the electronic device can be well supported in both the unfolded state and the folded state, thereby replacing the method of using two relatively movable comb-tooth structures to support the flexible display screen 400 in the electronic device of the related art, thereby solving the problem that when the electronic device of the related art uses two relatively movable comb-tooth structures to support the flexible screen, the comb-tooth structures have relatively serious friction during the unfolding or contraction of the flexible screen, which in turn causes abnormal noise. Moreover, the rotating support member 300 supports the flexible display screen 400 through the edges, thereby making the rotating support member 300 have a higher strength when supporting the flexible display screen 400, thereby solving the problem that the electronic device of the related art uses a comb-tooth structure and has a weak strength.

[0066] In an optional embodiment, the second body 200 and the plurality of rotating supports 300 may be connected via a first transmission mechanism. When the second body 200 moves to a position avoiding the plurality of rotating supports 300, the second body 200 may be connected to the plurality of rotating supports 300 via the first transmission mechanism, so that the plurality of rotating supports 300 rotate along with the movement of the second body 200. The second body 200 moves to a position avoiding the plurality of rotating supports 300, which means that the second body moves to a position misaligned with the plurality of rotating supports 300.

[0067] Specifically, the first transmission mechanism may be a connecting rod mechanism, a gear mechanism, etc. There are many ways to set the first transmission mechanism, and no specific limitation is made here.

[0068] The embodiment of the present application sets up a first transmission mechanism, so that when the second body 200 moves to a position to avoid the multiple rotating support members 300, the second body 200 can use the first transmission mechanism to make the multiple rotating support members 300 rotate following the movement of the second body 200, thereby generating a linkage between the second body 200 and the multiple rotating support members 300 through the first transmission mechanism, thereby making the coordination relationship between the movement of the second body 200 and the rotation of the rotating support members 300 more stable.

[0069] Specifically, in the embodiment in which the first transmission mechanism is provided, when the second body 200 is moved relative to the first body 100 by manual drive, the second body 200 and the rotating support member 300 do not need to be provided with a driving member to drive the second body 200 to move and the rotating support member 300 to rotate. In the case where the second body 200 is driven to move or the rotating support member 300 is driven to rotate by the driving member, it is sufficient to provide a driving member on only one of the second body 200 and the rotating support member 300, and the linkage is achieved through the transmission of the first transmission mechanism, so that the movement of the second body 200 and the rotating support member 300 can be achieved by fewer driving members.

[0070] Specifically, the first transmission mechanism may include a first rack 510, a first gear 520, an intermediate gear set 530, a second rack 540 and a third rack 550. The first rack 510 may be provided on the side of the second body 200 facing away from the flexible display screen 400, and the first rack 510 may extend along the moving direction of the second body 200, and the orientation of the teeth of the first rack 510 may be parallel to the extension surface of the second body 200. Of course, the orientation of the teeth of the first rack 510 may also be perpendicular to or at other angles to the extension surface of the second body 200. Specifically, the first rack 510 may be an integrated structure with the second body 200, and the first rack 510 may be a rack structure formed by a tooth groove provided on the side of the second body 200 facing away from the flexible display screen 400, so that the overall structure is relatively compact. Of course, the first rack 510 may be provided on the side of the second body 200 facing away from the flexible display screen 400 by welding, bonding, threaded connection, riveting, etc.

[0071] The first gear 520 can be rotatably disposed on the first body 100. There can be multiple first gears 520, and the multiple first gears 520 can correspond to and be connected to the multiple rotating support members 300. The second rack 540 can be connected to the third rack 550. The second rack 540 and the third rack 550 can be an integrated structure. Of course, when the second rack 540 and the third rack 550 are split structures, the second rack 540 and the third rack 550 can be connected by welding, bonding, threading, riveting, etc.

[0072] The second rack 540 and the third rack 550 can be slidably disposed on the first body 100, and the second rack 540 can be parallel to the third rack 550 and perpendicular to the first rack 510. The intermediate gear set 530 can be meshed with the first rack 510 and the second rack 540 respectively, and the first gear 520 can be meshed with the third rack 550. The movement of the third rack 550 can drive the first gear 520 to rotate, and the first gear 520 can drive the corresponding rotating support member 300 to rotate. The intermediate gear set 530 may include a second gear 531 and a third gear 532. The second gear 531 can be used to mesh with the first rack 510, and the third gear 532 can be used to mesh with the second rack 540.

[0073] During the specific implementation process, when the second body 200 moves relative to the first body 100 to the position where the first rack 510 is meshed with the intermediate gear set 530, the second body 200 continues to move, the first rack 510 is meshed with the intermediate gear set 530 to drive the intermediate gear set 530 to rotate, the intermediate gear set 530 is meshed with the second rack 540 to drive the second rack 540 to move, the second rack 540 is connected to the third rack 550 to drive the third rack 550 to move, the third rack 550 is meshed with the first gear 520 to drive the first gear 520 to rotate, and the first gear 520 can drive the corresponding rotating support member 300 to rotate, so that the rotating support member 300 is separated or abutted against the flexible display screen 400.

[0074] The embodiment of the present application discloses a specific first transmission mechanism, which is configured to include a first rack 510, a first gear 520, an intermediate gear set 530, a second rack 540 and a third rack 550, so that the transmission between the second body 200 and the rotating support member 300 is achieved through the cooperation of the gear and the rack, making the transmission between the second body 200 and the rotating support member 300 more stable.

[0075] Of course, in some other embodiments, the first transmission mechanism may include a first rod and a second rod, the first rod may be connected to the second body 200, the second rod may be rotatably connected to the first body 100 through its middle portion, the two ends of the second rod may be respectively connected to the first rod and the rotating support 300, the movement of the second body 200 may drive the first rod to move, the first rod may drive the second rod to rotate, so that the second rod drives the rotating support 300 to rotate. Of course, the first transmission mechanism may also be other implementations, which will not be described here.

[0076] Further, the first main body 100 may be provided with a first mounting groove, the side wall of the first mounting groove may be provided with an escape notch, the second rack 540 may be arranged in the escape notch, the third rack 550 may be slidably arranged in the first mounting groove, and the second rack 540 may be in limited contact with the side wall of the first mounting groove in the moving direction of the second main body 200, thereby avoiding excessive movement. When the second rack 540 and the third rack 550 are an integrated structure, the third rack 550 may be provided with a sliding buckle 551 and a sliding column 552, the sliding buckle 551 is used to be engaged with the first main body 100 so that the third rack 550 is installed on the first main body 100, and the sliding column 552 is used to slide on the first mounting groove of the first main body 100.

[0077] Specifically, the second rack 540 may be a trapezoidal structure, the teeth of the second rack 540 may be located at the small end of the trapezoidal structure, the small end of the trapezoidal structure may extend out of the avoidance notch, so that the intermediate gear set 530 is engaged with the second rack 540, and the large end of the trapezoidal structure may be in limited contact with the side wall surrounding the avoidance notch, so as to limit the movement of the second rack 540 in the moving direction of the second body 200. Of course, the limiting position of the second rack 540 in the moving direction of the second body 200 may also be other structures, such as by providing limiting protrusions, limiting recesses, etc. on the second rack 540 and the first body 100.

[0078] In the embodiment of the present application, a first mounting groove is opened on the first main body 100, and an avoidance notch is opened on the side wall of the first mounting groove, so that the second rack 540 can be arranged in the avoidance notch, and the third rack 550 can be slidably arranged in the first mounting groove, so that the second rack 540 can be limitedly contacted with the side wall of the first mounting groove in the moving direction of the second main body 200, so that the second rack 540 can be installed more stably in the moving direction of the second main body 200, thereby improving the assemblability between components and avoiding falling off.

[0079] Specifically, the second rack 540 and the third rack 550 may be oriented perpendicular to each other. Of course, the second rack 540 and the third rack 550 may also be oriented in other directions, for example, the second rack 540 and the third rack 550 may be oriented in the same direction or in opposite directions.

[0080] In an optional embodiment, the edge of the first gear 520 can be rotatably connected to the first body 100, and the first gear 520 is rotatably connected to the first body 100 through the first gear shaft 521. The rotation support 300 may include a first toggle protrusion 310, and the first toggle protrusion 310 may extend into a tooth gap of the first gear 520 and rotatably contact with the side wall of the tooth gap. Specifically, the edge of the first gear 520 may refer to the position where the tooth profile of the first gear 520 is located.

[0081] The embodiment of the present application connects the edge of the first gear 520 to the first body 100 in a rotatable manner, so that when the first gear 520 rotates relative to the first body 100, the teeth on the first gear 520 do not rotate around the center of the first gear 520, but rotate around the edge of the first gear 520, and then, by extending the first shifting protrusion 310 of the rotating support member 300 into a tooth gap of the first gear 520, when the first gear rotates, the first shifting protrusion 310 rotates with the side wall of the tooth gap to drive the rotating support member 300 to rotate, thereby realizing the separation and contact of the rotating support member 300 and the flexible display screen 400, and at the same time, fully utilizing the tooth gap of the first gear 520, so that there is no need to set other connection relationships between the first gear 520 and the rotating support member 300, thereby making the cooperation relationship between the first gear 520 and the rotating support member 300 simpler.

[0082] In an optional embodiment, the rotating support member 300 may include a first hinge shaft 320, the first hinge shaft 320 may be rotatably cooperated with the first main body 100, the axis of the first hinge shaft 320 may be consistent with the moving direction of the second main body 200, the first shifting protrusion 310 may be located on one side of the axis of the first hinge shaft 320, and the first shifting protrusion 310 and the first hinge shaft 320 may be located at both ends of the rotating support member 300 respectively.

[0083] In the embodiment of the present application, the first hinge shaft 320 is provided on the rotating support member 300, so that the rotating support member 300 can rotate around the first hinge shaft 320 when rotating, thereby making the rotation of the rotating support member 300 more stable, and the first toggle protrusion 310 is provided on one side of the axis of the first hinge shaft 320, and the first toggle protrusion 310 and the first hinge shaft 320 are respectively located at two ends of the rotating support member 300, so that the first toggle protrusion 310 and the first hinge shaft 320 are not colinear, so that when the rotating support member 300 rotates, its edges can be better separated from or abutted against the flexible display screen 400, and when the rotating support member 300 does not rotate, the first toggle protrusion 310 and the first hinge shaft 320 can keep the rotating support member 300 in the current position. Of course, this method is conducive to extending the force arm, so that the driving force for rotating the rotating support member 300 becomes correspondingly smaller, thereby reducing the energy consumption of the rotation drive.

[0084] In an optional embodiment, the first transmission mechanism may include a first slider 580 and a first threaded protrusion 590. The first slider 580 may be provided with a first threaded hole, and the first threaded protrusion 590 may be threadedly engaged with the first threaded hole. The first threaded protrusion 590 may be connected to the rotating support 300, the first threaded protrusion 590 may be connected to the first end of the rotating support 300, the second end of the rotating support 300 may be rotatably connected to the rotating shaft hole 130 of the first body 100, and the second end of the rotating support 300 may include a limiting cap 330.

[0085] The rotation support member 300 can be positioned and matched with the first body 100 in the moving direction of the second body 200 to limit the movement of the rotation support member 300 in the moving direction of the second body 200. When the second body 200 moves to a position to avoid multiple rotation support members 300, the second body 200 can be connected to the first slider 580, and the first slider 580 can move with the second body 200 to make the first threaded protrusion 590 rotate relative to the first threaded hole. Since the rotation support member 300 is positioned and matched with the first body 100 in the moving direction of the second body 200, the rotation support member 300 can rotate with the rotation of the first threaded protrusion 590, so that the corresponding rotation support member 300 rotates.

[0086] The second body 200 may be provided with a first protrusion 220, and when the second body 200 moves to a position avoiding the plurality of rotating supports 300, the first protrusion 220 is located at one end adjacent to the first body 100. When the second body 200 moves to a position avoiding the plurality of rotating supports 300, the second body 200 may be connected to the first slider 580 through the first protrusion 220, and the first slider 580 may move with the second body 200, for example, the first protrusion 220 pulls the first slider 580 to move.

[0087] The embodiment of the present application sets the first transmission mechanism to a structure including a first slider 580 and a first threaded protrusion 590, so that the first threaded protrusion 590 can be connected to the rotating support member 300, and the rotating support member 300 can be positioned and cooperated with the first body 100 in the moving direction of the second body 200, so that when the second body 200 moves to a position to avoid multiple rotating support members 300, the second body 200 can be connected to the first slider 580, and the first slider 580 can move with the second body 200 to make the first threaded protrusion 590 rotate relative to the first threaded hole, and the rotating support member 300 can rotate with the rotation of the first threaded protrusion 590, so that the corresponding rotating support member 300 rotates, so that the rotating support member 300 can support the flexible display screen 400.

[0088] Optionally, when the electronic device switches from the unfolded state to the folded state, the second body 200 can move through the relative rotation of the first slider 580 and the first threaded protrusion 590 to rotate the rotating support 300 to separate from the flexible display screen 400. At this time, the threaded matching relationship between the first slider 580 and the first threaded protrusion 590 is separated, and the second body 200 can continue to move so that the second body 200 is stacked on multiple rotating supports 300. Obviously, this can simplify the structure of the first transmission mechanism.

[0089] In an optional embodiment, the first body 100 may be provided with a strip groove 120, and the first slider 580 may be slidably disposed in the strip groove 120 and may slide along the extension direction of the strip groove 120. When the electronic device is in an expanded state, the first slider 580 may be in limited contact with the first end of the strip groove 120, and when the electronic device is in a folded state, the first slider 580 is in limited contact with the second end of the strip groove 120.

[0090] Specifically, when the first slider 580 moves from the second end of the strip groove 120 to the first end of the strip groove 120, the first slider 580 can drive the edge of the rotating support member 300 to rotate to a position in contact with the flexible display screen 400. When the first slider 580 moves from the first end of the strip groove 120 to the second end of the strip groove 120, the first slider 580 can drive the edge of the rotating support member 300 to rotate to a position separated from the flexible display screen 400.

[0091] In the embodiment of the present application, a strip groove 120 is provided in the first body 100 so that the first slider 580 can be slidably disposed in the strip groove 120 , thereby making the first slider 580 more stable when moving and can move more accurately under the guidance of the strip groove 120 .

[0092] Optionally, the second body 200 may include a reset protrusion 210 . During the movement of the second body 200 , the reset protrusion 210 may be used to contact the first slider 580 and push the first slider 580 to move to the second end of the strip groove 120 .

[0093] Specifically, when the second body 200 moves to a position avoiding multiple rotating support members 300, the reset protrusion 210 can be located at an end of the second body 200 away from the first body 100. In the process of the electronic device moving from the unfolded state to the folded state, the reset protrusion 210 is used to contact the first slider 580 and push the first slider 580 to move to the second end of the strip groove 120, so that the first slider 580 drives the edge of the rotating support member 300 to rotate to a position separated from the flexible display screen 400.

[0094] The first slider 580 may include a first pushing position 581, a second pushing position 582, and a sliding protrusion 583. The first pushing position 581 is used to abut against the first protrusion 220, so that the first slider 580 moves to the first end of the strip groove 120. The second pushing position 582 is used to abut against the reset protrusion 210, so that the reset protrusion 210 pushes the first slider 580 to move to the second end of the strip groove 120. The sliding protrusion 583 is used for sliding cooperation with the strip groove 120.

[0095] Specifically, the second body 200 may be provided with a plurality of avoidance channels 230 arranged at intervals, and the extension direction of the avoidance channels 230 may be consistent with the moving direction of the second body 200, and the avoidance channels 230 are used to avoid the rotating support member 300. In the process of the electronic device moving from the unfolded state to the folded state, the rotating support member 300 is initially in a state of supporting the flexible display screen 400, and at this time, the position of the rotating support member 300 in contact with the flexible display screen 400 moves along the extension direction of the avoidance channel 230, thereby avoiding the rotating support member 300 from interfering with the second body 200, and when the reset protrusion 210 contacts the first slider 580 and pushes the first slider 580 to move to the second end of the strip groove 120, the first slider 580 drives the edge of the rotating support member 300 to rotate to a position separated from the flexible display screen 400, and at this time, the electronic device is completely in the folded state.

[0096] The embodiment of the present application provides a plurality of avoidance channels 230 arranged at intervals on the second main body 200, so that when the electronic device is moved from the unfolded state to the folded state, when the electronic device is in any position that is not fully folded, the rotating support member 300 can still support the flexible display screen 400, thereby making the support capacity of the flexible display screen 400 stronger.

The pushing block 616 is sleeved on the screw rod 613 and is threadedly matched with the screw rod 613. The rotation of the screw rod 613 can drive the pushing block 616 to move along the axial direction of the screw rod 613. The light rod 614 can be arranged on both sides of the screw rod 613 and arranged parallel to the screw rod 613. The pushing block 616 can be provided with a through hole for the light rod 614 to pass through. The light rod 614 is used to guide and stabilize the movement of the pushing block 616. The rotating bearing 615 is installed at the ends of the screw rod 613 and the polished rod 614, and the pushing block 616 is fixed to the first body by the locking member 617. The driving motor 611, the reduction gear module 612, the screw rod 613, the polished rod 614, the rotating bearing 615, and the pushing block 616 are all installed on the module bracket 618. After the reduction gear module 612 is installed on the module bracket 618, the gear cover 619 and the module bracket 618 encapsulate the reduction gear module 612.
