Detailed Description

In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In this document, the terms "upper, lower, inner, outer" and the like are established based on the positional relationship shown in the drawings, and the corresponding positional relationship may be changed according to the drawings, so that the terms are not to be construed as absolute limitation of the protection scope; moreover, relational terms such as "first" and "second", and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

The curled screen supporting device provided by the invention can be suitable for electronic equipment such as mobile phones, tablet computers and the like. In the drawings, only structural features related to the present invention are shown, and other components of the electronic device are omitted, so that the omission does not affect understanding and implementation of the technical scheme of the present invention by those skilled in the art.

As shown in fig. 1 and 7, in the present embodiment, the roll screen support device includes a flexible screen 11, two reels 13, a first support member 20, and a second support member 30.

The flexible screen 11 is disposed around the two reels 13 and is switched between a curled state and an unwound state by a change in the distance between the two reels 13; specifically, when the distance between the two reels 13 becomes large, the flexible screen 11 is unfolded between the two reels 13, the display area thereof becomes large, the use by a user is facilitated, the visual experience is improved, when the distance between the two reels 13 becomes small, the flexible screen 11 is curled and retracted around the reels 13, the display area of the flexible screen 11 also becomes small, and the volume of the whole device becomes small, so that the device is convenient for the user to carry; of course, as shown in fig. 1 and 3, when the flexible screen 11 is in the curled state, it still has a display area, and the user can still perform various operations and uses on the electronic device in this state, that is, when the flexible screen 11 is in a different state, the use of the user is not affected, but rather, when the flexible screen 11 is in the curled state, the product cannot be used in normal operation.

The change of the distance between the two reels 13 may be achieved by manually pulling the reels 13 by a user, or may be achieved by sending a command to a control unit of the electronic device to control the reels 13.

As will be appreciated in connection with fig. 1, 5 to 9, the first support member 20 and the second support member 30 are capable of changing the operation mode according to the distance between the two reels 13, so as to better support the flexible screen 11 in different states.

As shown in fig. 1 and 3, the flexible screen 11 has a first display area in a curled state, the first display area being a surface area of the flexible screen 11 above the scroll 13 and on a side away from the scroll 13; at this time, the first supporting member 20 is in the first mode for supporting the flexible screen 11 and has the first supporting surface 1A adapted to the first display area, and the second supporting member 30 is in the working mode for not supporting the flexible screen 11, that is, in the curled state, the flexible screen 11 is supported only by the first supporting member 20, and the first supporting surface 1A of the first supporting member 20 is substantially the same as the first display area of the flexible screen 11 in the curled state, so as to ensure the display surface of the flexible screen 11 to be flat, provide reliable support for the flexible screen 11, and facilitate smooth touch operation of the display surface of the flexible screen 11 by the user in this state. In this state, the second support member 30 is located on the side of the first support member 20 facing away from the first support surface 1A, and the second support member 30 is located below the first support member 20 in the illustrated orientation.

As shown in fig. 7 to 9, the flexible screen 11 has a second display area, which is a surface area of the flexible screen 11 on the side above the reel 13 and away from the reel 13, in the unfolded state, the flexible screen 11 has a relatively large display surface, that is, the second display area is larger than the aforementioned first display area, as can be seen in comparison with fig. 1. At this time, the first support member 20 is in the second mode of supporting the flexible screen 11, the first support member 20 has a hollowed-out area and a face, the second support member 30 is in the working mode of supporting the flexible screen 11, the second support member 30 includes a protrusion 31 inserted into the hollowed-out area, the protrusion 31 and the face of the first support member 20 are coplanar, and the surface of the protrusion 31 and the face form a second support surface 1B adapted to the second display area, that is, the second support surface 1B includes the face of the first support member 20 and the surface of the protrusion 31 of the second support member 30.

Under the unfolding state of the flexible screen 11, the first supporting component 20 and the second supporting component 30 support the flexible screen 11 together, so that the display surface of the flexible screen 11 in the unfolding state basically has supporting force everywhere, the flatness is good, the phenomenon of uneven height can not occur during touch operation, and the user experience is effectively improved.

In this embodiment, the flexible screen 11 has a display surface and a mounting surface that are disposed opposite to each other, the display surface is relatively close to the reel 13, and the mounting surface is relatively far from the reel 13, and it is understood that when the first support member 20 or the second support member 30 supports the flexible screen 11, the mounting surface of the flexible screen 11 is supported with respect to the display surface; an adsorption layer 12 is arranged on the mounting surface of the flexible screen 11, and the adsorption layer 12 can generate magnetism to be attracted and fixed with the first support surface 1A or the second support surface 1B, so that reliable connection between the flexible screen 11 and the first support surface 1A or the second support surface 1B is ensured.

When the flexible screen 11 is switched between the curled state and the unfolded state in specific application, the adsorption layer 12 can be controlled to cancel magnetism, so that the flexible screen 11 is prevented from being blocked in the state switching process, or friction between the flexible screen 11 and a supporting surface is increased to damage the flexible screen 11. The control of the generation and cancellation of magnetism by the attraction layer 12 can be controlled by a control section (for example, a control circuit) of the electronic device.

In this embodiment, the roll screen support apparatus further includes a first transmission mechanism 40 and a second transmission mechanism 50.

The first transmission mechanism 40 is configured to drive the first support member 20 to move to switch between a first position for supporting the flexible screen 11 and a second position for separating from the flexible screen 11, when the first support member 20 is in the first mode (the flexible screen 11 is in a curled state as shown in fig. 1 and 3) or the second mode (the flexible screen 11 is in an unfolded state as shown in fig. 7 and 9) for supporting the flexible screen 11, the first support member 20 is in the first position, and the first support member 20 is in the second position, i.e. the position separated from the flexible screen 11 during the switching process of the flexible screen 11 between the curled state and the unfolded state, at this time, the magnetism of the adsorption layer 12 is cancelled, and the first support member 20 can be separated from the flexible screen 11, so as to avoid adverse effects on the state change of the flexible screen 11, which can be understood with reference to fig. 5. In other words, the first support member 20 has two different modes of operation in the first position, both of which support the flexible screen 11.

The second transmission mechanism 50 is configured to drive the second support member 30 to move between a third position for supporting the flexible screen 11 and a fourth position for separating from the flexible screen 11, where the second support member 30 is located below the first support member 20 in the orientation of fig. 1, because the second support member 30 only supports the flexible screen 11 when in the unfolded state, and therefore the second support member 30 is located in the third position in the operating mode for supporting the flexible screen 11, as shown in fig. 7 and 9, and the second support member 30 is located in the fourth position in the operating mode for not supporting the flexible screen 11, as shown in fig. 1 and 3, and at this time, the second support member 30 is located on the side of the first support member 20 facing away from the first support surface 1A.

Referring to fig. 1,3, 6 and 10, in the present embodiment, the first supporting member 20 includes a first connecting member 22 and a plurality of supporting portions 21, and the plurality of supporting portions 21 are connected to the first connecting member 22, wherein the first connecting member 22 can stretch along the expanding direction of the flexible screen 11, i.e. the first connecting member 22 can stretch along the direction perpendicular to the axial direction of the spool 13, so as to drive the supporting portions 21 to move.

In the curled state of the flexible screen 11, when the first supporting member 20 is in the first position and in the first mode, the first connector 22 is in the retracted state, and the plurality of supporting portions 21 are arranged in close proximity in the direction of deployment of the flexible screen 11, as shown in fig. 1 and 3, the surface of each supporting portion 21 forms a first supporting surface 1A for supporting the flexible screen 11.

It should be noted that the arrangement of the plurality of support portions 21 in close proximity does not indicate that there is absolutely no gap between the adjacent support portions 21; in practical applications, there is a machining error, and in order to ensure the operational reliability of the support portions 21, a gap is allowed between adjacent support portions 21 on the basis of ensuring that the flexible panel 11 in a curled state can be reliably supported.

In the process of unfolding the flexible screen 11, the first connecting piece 22 is driven to stretch out, the supporting parts 21 move along the unfolding direction of the flexible screen 11 along with the stretching out of the first connecting piece 22, the gap between two adjacent supporting parts 21 is increased, as shown in fig. 6, when the flexible screen 11 is in the unfolded state, the first supporting part 20 is in the first position and is in the second mode, at this time, the first connecting piece 22 is in the stretching out state, the supporting parts 21 are distributed at intervals along the unfolding direction of the flexible screen 11, the hollow area comprises a gap S between the two adjacent supporting parts 21, and the face, namely the supporting part 21 faces the surface of the flexible screen 11, as shown in fig. 10.

As shown in fig. 1, 3, 6 and 11, in the present embodiment, the second support member 30 includes a second link 32 and a plurality of protrusions 31, the plurality of protrusions 31 are connected to the second link 32, and the second link 32 is capable of expanding and contracting in the expanding direction of the flexible screen 11. The structural composition of the second support member 30 and the operational relationship of the associated structures are similar to those of the first support member 20.

In the curled state of the flexible screen 11, the second supporting member 30 is in the fourth position and is in the working mode of the non-supporting flexible screen 11, the second connecting member 32 is in the retracted state, the plurality of protruding portions 31 are arranged in close proximity along the direction of deployment of the flexible screen 11, the protruding portions 31 are located on the side of the supporting portion 21 facing away from the first supporting surface 1A, and the surfaces of the protruding portions 31 are arranged in parallel with the surfaces of the supporting portion 21, as can be understood with reference to fig. 1 and 3.

In the process of unfolding the flexible screen 11, as the flexible screen 11 is unfolded, the second connecting piece 32 stretches out to drive the plurality of protruding portions 31 to move along the unfolding direction of the flexible screen 11, and the gap between two adjacent protruding portions 31 is gradually increased, as shown in fig. 6.

In the unfolded state of the flexible screen 11, the second supporting member 30 is in the third position and is in the working mode for supporting the flexible screen 11, the second connecting piece 32 is in the extended state, the plurality of protruding portions 31 are arranged at intervals along the unfolded direction of the flexible screen 11, as shown in fig. 11, and each protruding portion 31 can be inserted between the two supporting portions 21 of the first supporting member 20, that is, each protruding portion 31 fills the hollowed-out area of the first supporting member 20, so that the surface of the protruding portion 31 and the surface of the supporting portion 21 form a second supporting surface 1B adapted to the second display area of the flexible screen 11, and obviously, at this time, the protruding portion 31 is coplanar with the supporting portion 21, as shown in fig. 7 to 9. It will be appreciated that, when the flexible screen 11 is in the deployed state, the projections 31 of the second support member 30 correspond in position to the spaces S between adjacent two support portions 21 of the first support member 20,

In the illustrated example, each support portion 21 of the first support member 20 has a rectangular plate-like structure, and accordingly, the space S formed between the two support portions 21 has a rectangular shape, and each projection 31 of the second support member 30 has a rectangular structure matching the shape of the space S; it is understood that in other embodiments, the shapes of the support portion 21 and the projection 31 may vary as long as the projection 31 and the space S can be matched.

In particular, when the first connecting piece 22 of the first supporting member 20 includes a first telescopic assembly, where the first telescopic assembly includes a plurality of first telescopic units connected in sequence, each first telescopic unit includes a fixing portion and a telescopic portion, the telescopic portion can be telescopic along the unfolding direction of the flexible screen 11 with respect to the fixing portion of the first telescopic unit, and the supporting portion 21 is connected with the fixing portion or the telescopic portion of the first telescopic unit, it can be understood that one supporting portion 21 is connected with one first telescopic unit, so that the distance between two reels 13 is increased, the telescopic portion of each first telescopic unit stretches out along with the flexible screen 11 in the unfolding process of the flexible screen 11, the distance between two adjacent supporting portions 21 stretches out to form a gap S, and the reverse operation is performed, that is, the distance between two reels 13 is reduced, and the telescopic portion of each first telescopic unit is retracted with respect to the fixing portion in the curling process of the flexible screen 11, so that the supporting portions 21 are rearranged. The extension length of the telescopic portion of the first telescopic unit may be determined, the size of the supporting portion 21 may be determined, and the space S between two adjacent supporting portions 21 may be determined after the flexible screen 11 is unfolded, and the second connection member 32 of the second supporting member 30 may be disposed accordingly, so as to ensure that each protruding portion 31 of the second supporting member 30 can be inserted into the space S at a corresponding position after the flexible screen is unfolded.

In this embodiment, the second transmission member includes a second transmission rod 521 and a second sliding rod 522, the spool 13 has a second chute 132, the second sliding rod 522 is slidingly engaged with the second chute 132, one end of the second transmission rod 521 is connected to the second rotating shaft 51, the other end is connected to the second sliding rod 522, and is connected to an end of the second supporting member 30, specifically, the protrusion 31 of the second supporting member 30 at the end is connected to the second transmission rod 521, or the second connector 32 of the second supporting member 30 is connected to the second transmission rod 521; when the second rotating shaft 51 rotates, the second transmission rod 521 rotates to drive the second sliding rod 522 to slide along the second sliding groove 132, and simultaneously drive the second supporting member 30 to act; obviously, the second sliding groove 132 is an arc-shaped groove with the center of the second rotating shaft 51 as a circle, and the second sliding rod 522 and the second sliding groove 132 may limit the position of the second transmission rod 521 rotating along with the second rotating shaft 51, so as to ensure that the second supporting member 30 can be switched between the aforementioned third position and fourth position.

To limit the sliding position of the second sliding rod 522, the second sliding chute 132 has two limiting surfaces, which are two slot end wall surfaces of the second sliding chute 132, as shown in fig. 2, one of the two slot end wall surfaces of the second sliding chute 132 is relatively far from the center of the flexible screen 11, and the other is relatively close to the center of the flexible screen 11; when the second slide bar 522 abuts against a groove end wall surface of the second slide groove 132 relatively near the center of the flexible screen 11, the second supporting member 30 is in a fourth position where the flexible screen 11 is not supportable, as shown in fig. 1 to 3 and fig. 5 and 6; when the second slide bar 522 abuts against the groove end wall surface of the second slide groove 132 relatively far from the center of the flexible screen 11, the second support member 30 is in a third position where the flexible screen 11 can be supported, as shown in fig. 7 and 9.

For simplifying the structure and facilitating the assembly, in the concrete implementation, for the same reel 13, the first rotating shaft 41 and the second rotating shaft 52 mounted on the same reel 13 are coaxially arranged and coincide with the central axis of the reel 13; like this, first spout 131 and second spout 132 are the arc groove that uses the center of spool 13 as the centre of a circle, and specifically, the radius of second spout 132 is less than first spout 131 and sets up, like this, second support member 30 can not cause the influence to first support member 20, combines fig. 1, 5 and 6, and flexible screen 11 is in crimping state and expansion in-process, and first support member 20 all is located the top of second support member 30, and the convenience supports flexible screen 11 under the crimping state, also makes things convenient for flexible screen 11's state switching in-process, breaks away from flexible screen 11. On the basis of this, it will be appreciated that the slot end wall surfaces of the first and second runners 131, 132 remote from the flexible screen 11 are located at the same radial position of the spool 13.

In a specific arrangement, the radian of the first chute 131 is smaller than that of the second chute 132, and the second support member 30 is generally located below the first support member 20, so as to avoid interference with the second support member 30 when the first support member 20 is switched to the second position.

Specifically, after the first rotating shaft 41 and the second rotating shaft 51 are coaxially disposed, they may be combined into one shaft, that is, the first rotating shaft 41 and the second rotating shaft 51 are the same shaft.

When the flexible screen 11 is required to be unfolded from the curled state shown in fig. 1, the adsorption layer 12 is controlled to cancel magnetism, the magnetic attraction between the supporting parts 21 of the first supporting component 20 and the adsorption layer 12 is eliminated, then the first transmission mechanism is controlled to act to drive the first supporting component 20 to switch from the first position shown in fig. 1 to the second position shown in fig. 5, in the state shown in fig. 5, the distance between the two winding shafts 13 is unchanged, the state of the second supporting component 30 is unchanged, at this time, the first supporting component 20 is separated from the flexible screen 11, the distance between the two winding shafts 13 can be controlled to be increased, as the distance between the supporting parts 21 of the first supporting component 20 is increased, the distance between the protruding parts 31 of the second supporting component 30 is also started, as shown in fig. 5, when the flexible screen 11 is switched to the unfolded state along with the two winding shafts 13, the first transmission mechanism is controlled to drive the first supporting component 20 to switch to the first position shown in fig. 7 again, but in the state of fig. 5, the first supporting component 20 is different from the state shown in fig. 1, at this time, the distance between the second supporting component 11 is controlled to be in the second supporting component 11 is driven to be in the second position shown in the second supporting mode, the protruding parts 31 are driven to be in the second supporting part 1, and the protruding parts 31 are formed to face the second supporting part 1, and the second supporting part is formed to face a gap 1, and the magnetic gap is formed between the second supporting part 31 is formed, and the second supporting part is located on the second supporting part 1 side surface 1, and the second supporting part is in the second supporting part is opposite side surface 31.
