In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

In this article, the terms of orientation such as "upper, lower, inner and outer" are established based on the positional relationship shown in the accompanying drawings, and the corresponding positional relationship may also change according to different drawings. It should not be construed as an absolute limitation on the scope of protection; moreover, relative terms such as "first" and "second" are only used to distinguish one element of the same name from another, not necessarily Any such actual relationship or order between these components is required or implied.

The curling screen supporting device provided by the present invention can be applied to electronic devices such as mobile phones and tablet computers. The drawings only show the structural features related to the present invention, and other components of the electronic device are omitted. Such omission does not affect the understanding and implementation of the technical solutions of the present invention by those skilled in the art.

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

The flexible screen 11 is arranged around the two reels 13, and switches between the rolled state and the unfolded state by changing the distance between the two reels 13; specifically, when the distance between the two reels 13 becomes larger, the flexible screen 11 is unfolded between the two reels 13, and its display area becomes larger, which is convenient for users to use and enhances the visual experience. When the distance between the two reels 13 becomes smaller, the flexible screen 11 is curled around the reels 13 and retracted, and the flexible screen 11 The display area of the flexible screen 11 also becomes smaller, and the volume of the entire device becomes smaller, which is convenient for the user to carry; of course, as shown in FIG. 1 and FIG. 3 , when the flexible screen 11 is in the curled state, it still has a display area, and the user can still use it in this state. Various operations and use of the electronic device, that is, different states of the flexible screen 11 do not affect the use of the user, which does not mean that the product cannot be used normally when the flexible screen 11 is in a curled state.

The change of the distance between the two reels 13 can be realized by manually pulling the reels 13 by the user, or by sending commands to the control part of the electronic device to control the movements of the reels 13 .

1 , 5 to 9 , the first support member 20 and the second support member 30 can change the working mode as the distance between the two reels 13 changes, so as to better support the flexible screen 11 in different states.

As shown in FIG. 1 and FIG. 3 , when the flexible screen 11 is in a rolled state, the flexible screen 11 has a first display area, and the first display area is the surface area of the flexible screen 11 located above the scroll 13 and away from the scroll 13; this , the first supporting member 20 is in the first mode of supporting the flexible screen 11 and has a first supporting surface 1A adapted to the first display area, and the second supporting member 30 is in the working mode of not supporting the flexible screen 11, that is, That is to say, in the rolled state, the flexible screen 11 is only supported by the first support member 20, and the first support surface 1A of the first support member 20 is substantially the same as the first display area of the flexible screen 11 in the rolled state, so as to ensure the flexible screen 11 The display surface of the flexible screen 11 is flat, which provides a reliable support for the flexible screen 11, so that the user can smoothly perform touch operations on the display surface of the flexible screen 11 in this state. In this state, the second support member 30 is located on the side of the first support member 20 away from the first support surface 1A. In the illustrated orientation, the second support member 30 is located below the first support member 20 .

As shown in FIG. 7 to FIG. 9 , in the unfolded state of the flexible screen 11, the flexible screen 11 has a second display area, and the second display area is the surface area of the flexible screen 11 located above the scroll 13 and away from the scroll 13, for comparison As can be seen from FIG. 1 , 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. At this time, the first supporting member 20 is in the second mode of supporting the flexible screen 11, the first supporting member 20 has a hollow area and a face, the second supporting member 30 is in the working mode of supporting the flexible screen 11, and the second supporting member 30 includes inserting The protruding portion 22 of the hollow area, the protruding portion 22 and the face of the first support member 20 are coplanar, and the surface and the face of the protruding portion 22 form a second supporting surface 1B adapted to the second display area, that is, The second support surface 1B includes the surface of the first support member 20 and the surface of the protruding portion 22 of the second support member 30 .

In the unfolded state of the flexible screen 11, the first support member 20 and the second support member 30 jointly support the flexible screen 11, ensuring that the display surface of the flexible screen 11 in this state basically has a supporting force everywhere, and the flatness is good. There will be no uneven phenomenon during operation, which effectively improves the user experience.

In this embodiment, the flexible screen 11 has a display surface and an installation surface arranged oppositely, the display surface is relatively close to the reel 13, and the installation surface is relatively far away from the reel 13. It can be understood that the installation surface is close to the first support member 20 and the second support relative to the display surface. When the flexible screen 11 is supported by the first support member 20 or the second support member 30, the mounting surface of the flexible screen 11 is supported; the mounting surface of the flexible screen 11 is provided with an adsorption layer 12, and the adsorption layer 12 can The magnetism is generated to attract and fix with the first support surface 1A or the second support surface 1B, so as to ensure the reliable connection between the flexible screen 11 and the first support surface 1A or the second support surface 1B.

In specific applications, when the flexible screen 11 switches between the curled state and the unfolded state, the adsorption layer 12 can be controlled to cancel the magnetism, so as to prevent the flexible screen 11 from being stuck during the state switching process, or increase the friction between the flexible screen 11 and the supporting surface However, the flexible screen 11 is damaged. The control of generating and demagnetizing the adsorption layer 12 can be controlled by a control unit (eg, a control circuit) of the electronic device.

In this embodiment, the curling screen supporting device further includes a first transmission mechanism 40 and a second transmission mechanism 50 .

The first transmission mechanism 40 is used to drive the first supporting member 20 to move to switch between the first position supporting the flexible screen 11 and the second position disengaging the flexible screen 11 . When the first supporting member 20 is in the first position supporting the flexible screen 11 In one mode (the flexible screen 11 is in a rolled state, as shown in FIGS. 1 and 3 ) or in the second mode (the flexible screen 11 is in an unfolded state, as shown in FIGS. 7 and 9 ), the first supporting member 20 is located on the first When the flexible screen 11 is switched between the curled state and the unfolded state, the first support member 20 is in the second position, that is, the position separated from the flexible screen 11. At this time, the magnetism of the aforementioned adsorption layer 12 is cancelled, and the first The support member 20 can be detached from the flexible screen 11 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 working modes in the first position, and both support the flexible screen 11 in the two working modes.

The second transmission mechanism 50 is used for driving the second supporting member 30 to switch between the third position supporting the flexible screen 11 and the fourth position disengaging the flexible screen 11, because the second supporting member 30 is only in the unfolded state of the flexible screen 11. Therefore, in the working mode of supporting the flexible screen 11, the second supporting member 30 is in the third position. As shown in FIG. 7 and FIG. 9, the second supporting member 30 is not supporting the flexible screen 11. In the working mode, in the fourth position, as shown in FIG. 1 and FIG. 3 , at this time, the second support member 30 is located on the side of the first support member 20 away from the first support surface 1A, in terms of the orientation in FIG. 1 , the second support member 30 is located below the first support member 20 .

Please refer to FIG. 1 , FIG. 3 , FIG. 6 , and FIG. 10 , in this 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 all connected to the first connecting member 22 The first connecting member 22 can expand and contract along the unfolding direction of the flexible screen 11 , that is, the first connecting member 22 can expand and contract along the direction perpendicular to the axis direction of the reel 13 to drive the support portion 21 to move.

When the flexible screen 11 is in a rolled state, when the first supporting member 20 is in the first position and in the first mode, the first connecting member 22 is in a retracted state, and the plurality of supporting parts 22 are arranged next to each other along the unfolding direction of the flexible screen 11 , As shown in FIGS. 1 and 3 , the surface of each support portion 22 forms a first support surface 1A for supporting the flexible screen 11 .

It should be noted that the fact that a plurality of support parts 22 are arranged next to each other does not mean that there is absolutely no gap between adjacent support parts 22; in practical applications, there are machining errors, and at the same time, in order to ensure the reliability of the operation of the support parts 22, it is necessary to ensure that the support parts 22 can be On the basis of reliably supporting the flexible screen 11 in the rolled state, a gap is allowed between adjacent supporting parts 22 .

During the unfolding process of the flexible screen 11, the first connector 22 is driven to extend, and the plurality of support parts 22 move along the unfolding direction of the flexible screen 11 along with the extension of the first connector 22, and two adjacent support parts 22 The gap between them increases. As shown in FIG. 6 , when the flexible screen 11 is in the unfolded state, the first support member 20 is in the first position and in the second mode, and at this time, the first connecting member 22 is in the extended state, A plurality of support parts 22 are arranged at intervals along the unfolding direction of the flexible screen 11 , the aforementioned hollow area includes a gap S between two adjacent support parts 21 , and the aforementioned face is the surface of the support part 21 facing the flexible screen 11 , as shown in FIG. 10 . Show.

As shown in FIG. 1 , FIG. 3 , FIG. 6 and FIG. 11 , in this embodiment, the second support member 30 includes a second connecting member 32 and a plurality of protruding parts 31 , and the multiple protruding parts 31 and the second connecting member 32 is connected, and the second connecting member 32 can expand and contract along the unfolding direction of the flexible screen 11 . The structural composition of the second support member 30 and the action relationship of the related structures are similar to those of the first support member 20 .

When the flexible screen 11 is in a curled state, the second support member 30 is in the fourth position and is in a working mode that does not support the flexible screen 11 , the second connecting member 32 is in a retracted state, and the plurality of protruding parts 31 are unfolded along the flexible screen 11 . The directions are arranged next to each other, and the protruding portion 31 is located on the side of the supporting portion 21 away from the first supporting surface 1A.

During the unfolding process of the flexible screen 11 , with the unfolding of the flexible screen 11 , the second connecting member 32 extends out, and drives the plurality of protruding parts 31 to move along the unfolding direction of the flexible screen 11 , between two adjacent protruding parts 31 . The gap gradually increases, as shown in Figure 6.

When the flexible screen 11 is in the unfolded state, the second support member 30 is in the third position and is in the working mode of supporting the flexible screen 11 , the second connecting member 32 is in the extended state, and the plurality of protruding parts 31 are along the unfolding direction of the flexible screen 11 . They are arranged at intervals, as shown in FIG. 11 , and each protruding part 31 can be inserted between the two supporting parts 21 of the first supporting part 20 , that is, each protruding part 31 fills the hollow area of the first supporting part 20 , so that the protruding parts 31 are arranged at intervals. The surface of the outgoing 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. Obviously, the protruding portion 31 and the supporting portion 21 are coplanar at this time, as shown in FIGS. 7 to 7 . 9 shown. It can be understood that when the flexible screen 11 is in the unfolded state, the protruding portion 31 of the second supporting portion 30 corresponds to the position of the gap S between the two adjacent supporting portions 21 of the first supporting portion 20 ,

In the illustrated example, each support portion 21 of the first support member 20 has a rectangular plate-like structure, and correspondingly, the gap S formed between the two support portions 21 also has a rectangular shape. The protruding portion 31 is a rectangular structure matching the shape of the gap S; it can be understood that in other embodiments, the shapes of the support portion 21 and the protruding portion 31 can be changed, as long as the protruding portion 31 and the gap S can be matched.

In a specific implementation, the first connector 22 of the first support member 20 includes a first telescopic assembly, the first telescopic assembly includes a plurality of first telescopic units connected in sequence, and each first telescopic unit includes a fixed portion and a telescopic portion, The telescopic portion can be expanded and contracted relative to the fixed portion in the unfolding direction of the flexible screen 11, and the support portion 21 is connected to the fixed portion or the telescopic portion of the first telescopic unit. It can be understood that one support portion 21 is connected to one first telescopic unit. The distance between the reels 13 increases. During the unfolding process of the flexible screen 11, the telescopic part of each first telescopic unit is extended accordingly, and the distance between the two adjacent support parts 21 is widened to form a gap S, and the operation is reversed. That is, the distance between the two reels 13 becomes smaller, and during the rolling process of the flexible screen 11, the telescopic part of each first telescopic unit retracts relative to the fixed part, so that the supporting parts 21 are re-arranged in close proximity. The extension length of the telescopic part of the first telescopic unit can be determined, the size of the support part 21 can be determined, and after the flexible screen 11 is unfolded, the gap S between the two adjacent support parts 21 is determined, and the second support part 30 The two connecting pieces 32 can be arranged accordingly to ensure that each protruding portion 31 of the second supporting portion 30 can be inserted into the gap S at the corresponding position after deployment.

Referring to FIG. 10 , the first supporting member 20 has two first connecting pieces 22 , the two first connecting pieces 22 are arranged in parallel, and the support portion 21 is arranged between the two first connecting pieces 22 to ensure the reliability of the action and the stability.

The second connecting member 32 of the second supporting member 30 can be configured similarly to the first connecting member 22, that is, the second connecting member 32 includes a second telescopic assembly, and the second telescopic assembly includes a plurality of second telescopic units connected in sequence, The second telescopic unit includes a fixed part and a telescopic part. The telescopic part can expand and contract relative to the fixed part along the unfolding direction of the flexible screen 11. The protruding part 31 is connected to the fixed part or the telescopic part of the second telescopic unit. Similarly, one protruding part 31 When a second telescopic unit is connected, the states of the plurality of protruding parts 31 change with the expansion and contraction of the plurality of second telescopic components, which will not be described in detail.

Referring to FIG. 11 , the second support member 30 also has two second connecting pieces 32 , the two second connecting pieces 32 are arranged in parallel, and the protruding portion 31 is arranged between the two second connecting pieces 32 to ensure reliable action stability and stability.

In other embodiments, the first connecting member 22 and the second connecting member 32 may also adopt other methods, such as including a sliding rail and a roller that can roll along the sliding rail. The position is changed as the roller rolls along the slide rail, so as to realize the mode switching of the first support member 20 or the second support member 30. Another example can be a controllable elastic member, which drives the support portion 21 or the protrusion through the elastic expansion and contraction of the elastic member. The action of the outlet portion 31 realizes the change of position, thereby switching the mode of the first support member 20 or the second support member 30 .

In order to simplify the structural arrangement, in this embodiment, the structures of the first transmission mechanism 40 and the second transmission mechanism 50 are similar.

Referring to FIGS. 1 to 4 , the first transmission mechanism 40 includes two first rotation shafts 41 and two first transmission members, the two first rotation shafts 41 are respectively disposed on the two reels 13 , and the axis direction of the first rotation shafts 41 is the same as that of the reels. The axes of 13 are parallel to each other, and the two ends of the first support member 20 are respectively connected with the two first rotating shafts 41 through two first transmission members.
