The support device for the curled screen provided by the invention can be suitable for electronic equipment such as mobile phones, tablet computers and the like. In each drawing, only the structural features relevant to the present invention are shown, and other components of the electronic device are omitted, so that the technical scheme of the present invention is not influenced by the omission of the components and the technical features of the electronic device.

As shown in fig. 1 and 7, in the present embodiment, the rolled 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 arranged around the two reels 13 and is switched between a rolled state and a unrolled 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 of the flexible screen 11 becomes large, the use by a user is facilitated, and the visual experience is improved; of course, as shown in fig. 1 and fig. 3, when the flexible screen 11 is in the rolled 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, the flexible screen 11 is in different states and does not affect the use of the user, that is, when the flexible screen 11 is in the rolled state, the product cannot be normally operated and used.

The change of the distance between the two reels 13 can be realized by manually pulling the reels 13 by a user, and the operation of the reels 13 can also be controlled by sending instructions to a control part of the electronic device.

As will be understood from fig. 1, 5 to 9, the first support member 20 and the second support member 30 can change the operation mode according to the distance between the two reels 13, so as to support the flexible screen 11 in different states.

As shown in fig. 1 and 3, in the rolled state of the flexible screen 11, the flexible screen 11 has a first display area, which is a surface area of the flexible screen 11 on a side above the reel 13 and away from the reel 13; at this time, the first supporting member 20 is in the first mode for supporting the flexible screen 11 and has a first supporting surface 1A adapted to the first display area, 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 that the display surface of the flexible screen 11 is flat, provide reliable support for the flexible screen 11, and facilitate smooth touch operation of the user 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 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, in the unfolded state of the flexible screen 11, the flexible screen 11 has a second display area, which is a surface area of the flexible screen 11 on a side above the rolling shaft 13 and away from the rolling shaft 13, and as can be seen from comparing 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 first display area. 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 portion, the second support member 30 is in the operating mode of supporting the flexible screen 11, the second support member 30 includes a projection 22 inserted into the hollowed-out area, the projection 22 is coplanar with the face portion of the first support member 20, and a surface and a face portion of the projection 22 form a second support surface 1B adapted to the second display area, that is, the second support surface 1B includes the face portion of the first support member 20 and the face portion of the projection 22 of the second support member 30.

When the flexible screen 11 is in the unfolded state, the first supporting part 20 and the second supporting part 30 support the flexible screen 11 together, so that the supporting force is basically provided at the display surface of the flexible screen 11 in the unfolded state, the flatness is good, the phenomenon of unevenness cannot occur during touch operation, and the user experience is effectively improved.

In the present embodiment, the flexible screen 11 has a display surface and a mounting surface which are oppositely arranged, the display surface is relatively close to the scroll 13, and the mounting surface is relatively far from the scroll 13, it can be understood that the mounting surface is close to the first supporting member 20 and the second supporting member 30 relative to the display surface, and when the flexible screen 11 is supported by the first supporting member 20 or the second supporting member 30, the mounting surface of the flexible screen 11 is supported; 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 fixedly attracted with the first supporting surface 1A or the second supporting surface 1B, so that reliable connection between the flexible screen 11 and the first supporting surface 1A or the second supporting surface 1B is ensured.

In the specific application, when the flexible screen 11 is switched between the curling state and the unfolding state, the adsorption layer 12 can be controlled to cancel magnetism, so that the flexible screen 11 is prevented from being clamped in the state switching process, or the flexible screen 11 is prevented from being damaged due to increased friction between the flexible screen 11 and the supporting surface. The control of the generation and removal of magnetism by the attracting 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 supporting component 20 to move to switch between a first position supporting the flexible screen 11 and a second position separated from the flexible screen 11, and when the first supporting component 20 is in a first mode (the flexible screen 11 is in a rolled state as shown in fig. 1 and 3) supporting the flexible screen 11 or in a second mode (the flexible screen 11 is in an unfolded state as shown in fig. 7 and 9), the first supporting component 20 is located at the first position, and during the switching process between the rolled state and the unfolded state of the flexible screen 11, the first supporting component 20 is located at the second position, i.e., a position separated from the flexible screen 11, at this time, the magnetism of the adsorption layer 12 is cancelled, and the first supporting component 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 to switch between a third position supporting the flexible screen 11 and a fourth position separated from the flexible screen 11, and because the second support member 30 supports the flexible screen 11 only when the flexible screen 11 is in the unfolded state, the second support member 30 is in the third position in the working mode of supporting the flexible screen 11, as shown in fig. 7 and 9, and the second support member 30 is in the fourth position in the working mode of not supporting the flexible screen 11, as shown in fig. 1 and 3, at this time, the second support member 30 is located on a side of the first support member 20 away from the first support surface 1A, and in the orientation in fig. 1, the second support member 30 is located below the first support member 20.

Referring to fig. 1, 3, 6, and 10, in the present embodiment, the first supporting component 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 extend and contract along the unfolding direction of the flexible screen 11, that is, the first connecting member 22 can extend and contract along the direction perpendicular to the axial direction of the winding shaft 13, so as to drive the supporting portions 21 to move.

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

It should be noted that the arrangement of the plurality of supporting portions 22 in close proximity does not mean that there is absolutely no gap between the adjacent supporting portions 22; in practical applications, there are machining errors, and in order to ensure the operational reliability of the support portions 22, gaps are allowed between adjacent support portions 22 while ensuring reliable support of the flexible panel 11 in the rolled state.

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

The structural composition of the second support member 30 and the associated structural and operational relationships are similar to those of the first support member 20.

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

In the unfolding process of the flexible screen 11, along with the unfolding of the flexible screen 11, the second connecting member 32 extends 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.
