Before explaining the technical scheme of the application, an application scenario of the application is explained.

With the increasing maturity of flexible screen technology, electronic devices with adjustable screen area size become an increasingly popular object for people. In the related art, the size of the screen area of the electronic device is usually made adjustable by folding, however, this method cannot gradually adjust the size of the screen area as required when adjusting the size of the screen area, and is not flexible enough. Specifically, the size of the screen area after folding is half of the size before folding, the size of the screen area changes in a jumping manner, and cannot gradually become larger or smaller in a gradual manner, so that the user experience is poor. Even though the scroll screen exists in the related art, the size of the screen area can be adjusted in a gradual manner, the scroll screen in the related art usually needs to be provided with a rotating shaft, and the whole scroll screen is large in volume and heavy in weight. Accordingly, the present application provides a new scroll screen and electronic device to solve the above-mentioned problems.

The technical solution of the present application will be further described with reference to the following embodiments and accompanying drawings.

Fig. 1 is a schematic structural view of a winding shaft screen 100 in a winding state, fig. 2 is a schematic structural view of the winding shaft screen 100 in fig. 1 in a winding state, fig. 3 is an exploded view of the winding shaft screen 100 in fig. 1, and fig. 4 is a schematic structural view of a spiral guide 2 of the winding shaft screen 100 in fig. 3.

Referring to fig. 1, 2 and 3, the spool screen 100 includes: a first housing 1, a helical guide 2 and a flexible screen 3. Wherein the first housing 1 has a receiving cavity, the spiral guide 2 is disposed on the first housing 1 and located in the receiving cavity, referring to fig. 3 and 4, the spiral guide 2 has a start end 21 and a stop end 22, the spiral guide 2 is spirally diverged from the start end 21 to the stop end 22, and a spiral radius R (spiral radius of the innermost circle shown in fig. 4) of the spiral guide 2 increases gradually in a direction from the start end 21 to the stop end 22 (i.e., a direction from inside to outside of the spiral guide 2 in fig. 4) so that the spiral guide 2 forms a spiral channel 20, the spiral channel 20 includes a channel opening 201 close to the stop end 22, the first housing 1 is provided with an opening 10 communicated with the channel opening 201, the flexible screen 3 is disposed in the spiral channel 20 in a reciprocating sliding manner along a spiral direction F of the spiral guide 2, so that the flexible screen 3 can gradually extend out of the spiral channel 20 from the channel opening 201 and the spiral channel opening 10 along the spiral direction F Or, the spiral duct 20 can be gradually accommodated from the opening 10 and the duct opening 201 (i.e., the state of the scroll screen 100 in fig. 1).

In the present embodiment, since the spiral guide 2 is formed by spirally diverging from the starting end 21 to the terminating end 22, and the spiral radius R of the spiral guide 2 gradually increases along the direction from the starting end 21 to the terminating end 22, the spiral guide 2 will form the spiral channel 20. Then, since the spiral guide 2 is provided on the first housing 1 and located in the accommodation chamber, the chamber mouth 201 of the spiral channel 20 and the opening 10 on the first housing 1 communicate with each other, and the flexible screen 3 is provided in the spiral channel 20 so as to be slidable back and forth in the spiral direction F of the spiral guide 2. Therefore, when the flexible screen 3 slides in the spiral direction F (i.e., clockwise in fig. 4), the flexible screen 3 can be gradually extended out of the spiral channel 20 from the channel opening 201 and the opening 10, so that the flexible screen 3 of the scroll screen 100 is gradually unfolded, and the screen area of the scroll screen 100 is gradually increased in a gradual manner until the scroll screen 100 is in the unfolded state. When the flexible screen 3 slides in the direction opposite to the spiral direction F (i.e., counterclockwise in fig. 4), the flexible screen 3 can be gradually accommodated in the spiral channel 20 from the opening 10 and the channel opening 201, so that the flexible screen 3 of the scroll screen 100 is gradually wound, and the screen area of the scroll screen 100 is gradually reduced in a gradual manner until the scroll screen 100 is in the wound state. Compared with the mode that the screen area changes in a jumping mode in the related art, the screen area of the scroll screen 100 changes in a gradual mode, the screen area changes in a very flexible mode, and therefore the user experience of the scroll screen 100 can be improved to a certain extent.

In addition, the flexible screen 3 can be arranged in the spiral cavity channel 20 in a reciprocating sliding manner along the spiral direction F of the spiral guide piece 2, a rotating shaft does not need to be additionally arranged, the reel screen 100 can be freely switched between the unfolding state and the rolling state, the structural design is very ingenious, and the weight of the whole reel screen 100 can be further reduced to a certain degree.

The spiral guide 2 may be disposed on the first housing 1 by welding, or may be disposed on the first housing 1 by other means, for example, may be disposed on the first housing 1 by gluing, which is not limited in the embodiment of the present application.

In addition, the shape of the first housing 1 may be a cylindrical shape, a triangular prism shape, a quadrangular prism shape, or the like, and the shape of the first housing 1 is not limited in the embodiment of the present application.

In an actual usage scenario, assuming that the scroll screen 100 is in the rolling state at first, when it is needed to gradually increase the screen area of the scroll screen 100 and make the scroll screen 100 in the unfolding state, first, a user may pull the flexible screen 3 toward a direction away from the first casing 1, at this time, the flexible screen 3 may gradually extend out of the spiral channel 20 from the cavity opening 201 and the opening 10 along the spiral direction F, so that the screen area of the scroll screen 100 gradually increases in a gradual manner, and the scroll screen 100 is made to be in the unfolding state. In the case that the scroll screen 100 is in the unfolded state, when the screen area of the scroll screen 100 needs to be gradually reduced and the scroll screen 100 is in the rolled state, firstly, the user can push the flexible screen 3 toward the direction close to the first housing 1, at this time, the flexible screen 3 can be gradually accommodated in the spiral channel 20 from the opening 10 and the channel opening 201 in the direction opposite to the spiral direction F, so that the screen area of the scroll screen 100 is gradually reduced in a gradual manner, and the scroll screen 100 is in the rolled state.

In some embodiments, referring to fig. 3, the first housing 1 includes a first bottom wall 11 and a second bottom wall 12 (not shown in fig. 3) disposed opposite to each other, and a peripheral wall 13 located between the first bottom wall 11 and the second bottom wall 12 and connecting the first bottom wall 11 and the second bottom wall 12, the first bottom wall 11, the second bottom wall 12 and the peripheral wall 13 together form a receiving cavity, the peripheral wall 13 is provided with an opening 10, an axis L of the spiral guide 2 is perpendicular to the first bottom wall 11 and the second bottom wall 12, and a side wall of the spiral guide 2 perpendicular to the axis is connected to the first bottom wall 11.

Under the condition that the axis L of the spiral guide 2 is perpendicular to the first bottom wall 11 and the second bottom wall 12, by connecting the side wall of the spiral guide 2 perpendicular to the axis with the first bottom wall 11, the whole side wall of the spiral guide 2 perpendicular to the spiral direction F can be connected with the first bottom wall 11, thus avoiding the situation that the spiral guide 2 collapses to cause the spiral channel 20 to be blocked, and ensuring that the structure of the whole spiral guide 2 is stronger and more stable.

Of course, the side wall perpendicular to the axis of the spiral guide 2 may also be connected to the second bottom wall 12, or the two side walls perpendicular to the axis of the spiral guide 2 may also be connected to the first bottom wall 11 and the second bottom wall 12, respectively, which is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 3, the number of the spiral guides 2 is two, the two spiral guides 2 are oppositely arranged at intervals in the direction (i.e., the X-axis direction in fig. 3) in which the first bottom wall 11 points to the second bottom wall 12, the side wall of one of the two spiral guides 2 is connected to the first bottom wall 11, the side wall of the other of the two spiral guides 2 is connected to the second bottom wall 12, and the flexible screen 3 includes a first end and a second end which are oppositely arranged in the direction in which the first bottom wall 11 points to the second bottom wall 12, and the first end and the second end are slidably arranged in the spiral channels 20 of the two spiral guides 2 respectively.

By making the number of the spiral guide members 2 two, the side wall of one of the two spiral guide members 2 is connected to the first bottom wall 11, and the side wall of the other one of the two spiral guide members 2 is connected to the second bottom wall 12, and the first end and the second end of the flexible screen 3 are slidably disposed in the spiral channels 20 of the two spiral guide members 2, respectively, the two ends of the flexible screen 3 can be supported by the two spiral guide members 2, so that the flexible screen 3 can slide more stably when sliding back and forth along the spiral direction F.

In addition, by connecting the side wall of one of the two spiral guides 2 with the first bottom wall 11 and connecting the side wall of the other one with the second bottom wall 12, when the first end and the second end of the flexible screen 3 are slidably disposed in the spiral channels 20 of the two spiral guides 2, the first bottom wall 11 and the second bottom wall 12 can both limit the flexible screen 3 in the direction in which the first bottom wall 11 points to the second bottom wall 12, so that the flexible screen 3 is limited between the first bottom wall 11 and the second bottom wall 12, and thus, the situation that the flexible screen 3 shakes in the direction in which the first bottom wall 11 points to the second bottom wall 12 can be avoided, and the flexible screen 3 slides more stably when sliding back and forth along the spiral direction F.

In addition, by arranging the two spiral guides 2 at intervals in the direction in which the first bottom wall 11 points to the second bottom wall 12, and slidably arranging the first end and the second end of the flexible screen 3 in the spiral channels 20 of the two spiral guides 2 respectively, the structures of the flexible screen 3 except the first end and the second end can not be contacted with the spiral guides 2 to generate friction, and thus, the situation that the flexible screen 3 is damaged by friction can be avoided to a certain extent.

In some embodiments, referring to fig. 2 and 3, the flexible screen 3 is provided with a chain 4, by means of which chain 4 the flexible screen 3 is slidably arranged in the helical channel 20 of the helical guide 2. By providing the flexible screen 3 with the chains 4 and slidably arranging the flexible screen 3 in the spiral channel 20 of the spiral guide 2 via the chains 4, it is possible to avoid to some extent the flexible screen 3 from being damaged by friction due to the direct contact between the flexible screen 3 and the spiral guide 2.

The chain 4 may be a flexible chain, and when the chain 4 is a flexible chain, on one hand, the situation that the spiral guide 2 is damaged due to collision of the chain 4 and the spiral guide 2 can be avoided. On the other hand, it is also more advantageous to house the chain 4 in the helical channel 20.

The flexible chain can be a rubber chain, a flexible plastic chain, etc., and only needs to be spirally accommodated in the spiral cavity channel 20 and can gradually extend out of the spiral cavity channel 20 from the cavity channel opening 201 and the opening 10 along the spiral direction F, and the embodiment of the application does not limit the chain 4.

Further, in some embodiments, referring to fig. 2 and 3, a chain 4 is disposed on each of the first end and the second end, and each of the first end and the second end is slidably disposed in the spiral channel 20 of each of the two spiral guides 2 via the chain 4. By making the first end and the second end slidably disposed in the spiral channels 20 of the two spiral guides 2 through the chains 4, respectively, the flexible screen 3 can be further protected, and the flexible screen 3 can be prevented from contacting the spiral guides 2, so that the flexible screen 3 can be better prevented from being damaged by friction.

In one possible implementation, referring to fig. 5, 6 and 7, the chain 4 includes: a plurality of chain main parts 41 and a plurality of supporting parts 42. Wherein, a plurality of chain main parts 41 are connected in sequence, each chain main part 41 can be arranged in the spiral cavity channel 20 in a sliding way, each chain main part 41 is provided with a through hole 411, and the through holes 411 on two adjacent chain main parts 41 are communicated with each other. The plurality of supporting pieces 42 are in one-to-one correspondence with the plurality of chain main parts 41, each supporting piece 42 is slidably disposed in the corresponding through hole 411, and adjacent two supporting pieces 42 are connected in sequence. When the flexible screen 3 is received in the spiral channel 20, the plurality of chain main parts 41 are all located in the spiral channel 20, and the supporting parts 42 are respectively received in the corresponding through holes 411. When the flexible screen 3 gradually extends out of the spiral channel 20 from the channel opening 201 and the opening 10 along the spiral direction F, the chain main parts 41 extend out of the spiral channel 20, and the supporting parts 42 can slide along the corresponding through holes 411, so that part of the supporting parts 42 are positioned in the through holes 411 of the adjacent chain main parts 41 to support the plurality of chain main parts 41 to keep straight.

In this embodiment, since each support member 42 is slidably disposed in the corresponding through hole 411, the support member 42 can be first slid into the corresponding through hole 411 so that the support member 42 is received in the corresponding through hole 411, with the spool screen 100 in the unwound state. Then, when the scroll screen 100 needs to be in the rolling state, the flexible screen 3 may be pushed in a direction close to the first housing 1, and at this time, in a process that the flexible screen 3 together with the plurality of chain main elements 41 are gradually accommodated in the spiral channel 20 from the opening 10 and the channel opening 201 in a direction opposite to the spiral direction F, the positional relationship between the chain main elements 41 and between the supporting elements 42 may be deformed, so that the plurality of chain main elements 41 and the plurality of supporting elements 42 together form a spiral structure matching the shape of the spiral channel 20, so that the scroll screen 100 is in the rolling state.

When the scroll screen 100 needs to be in the unfolded state, the flexible screen 3 can be pulled along the direction away from the first housing 1, at this time, the flexible screen 3 and the plurality of chain main parts 41 can simultaneously and gradually extend out of the spiral cavity channel 20 from the cavity channel 201 and the opening 10 along the spiral direction F, at this time, in order to support the flexible screen 3, so that the flexible screen 3 has a certain strength, the flexible screen 3 is prevented from being loosened and collapsed to be randomly deformed, the supporting parts 42 can be made to slide along the corresponding through holes 411, so that part of the supporting parts 42 slide into the adjacent through holes 411, so that the two adjacent chain main parts 41 are connected in series by the supporting parts 42, and further the plurality of chain main parts 41 can be supported to keep a straight line, so that the chains 4 become a straight rigid chain, so that when the scroll screen 100 is in the unfolded state, the flexible screen 3 can be ensured to have a certain strength, the flexible screen 3 is of a rigid flat structure, so that the use by a user is facilitated, and the use experience of the user can be improved.

By forming an included angle between two adjacent chain main elements 41, the plurality of chain main elements 41 can collectively form a spiral structure to be accommodated in the spiral channel 20. By making the two adjacent chain main parts 41 parallel to each other, the whole flexible screen 3 can be relatively flat when the flexible screen 3 gradually extends out of the spiral channel 20 from the channel opening 201 and the opening 10 along the spiral direction F.

The structure of the second flexible column 420 may be similar to that of the first flexible column 410, and specific reference may be made to the description of the first flexible column 410 in the foregoing embodiment, and details of the second flexible column 420 in this embodiment are not repeated.

It should be noted that the first end of the flexible screen 3 can be connected to the chain main part 41 in various ways, and in one possible implementation, referring to fig. 7, a slot 40 can be provided on the chain main part 41, and the first end of the flexible screen 3 can be snapped into the slot 40 to connect the first end of the flexible screen 3 with the chain main part 41. When the chain main part 41 is provided with the locking groove 40, the mode of connecting the first end of the flexible screen 3 with the chain main part 41 is very simple, and the manufacturing cost of the whole scroll screen 100 can be reduced to a certain extent. The second end of the flexible screen 3 may also be connected to the chain main part 41 in this way, and specific reference may be made to the description of the connection way between the first end of the flexible screen 3 and the chain main part 41, which is not described herein again.

It is understood that, in order to make it possible to support the plurality of chain main members 41 in a straight line when the partial supporting members 42 slide into the adjacent through holes 411, and thus to make the flexible screen 3 have a rigid flat plate-shaped structure, the chain main members 41 and the supporting members 42 may be made of hard materials, for example, in one possible implementation manner, the chain main members 41 and the supporting members 42 may be made of hard plastics, so that the flexible screen 3 has a rigid flat plate-shaped structure when the partial supporting members 42 slide into the adjacent through holes 411. Of course, the material of the chain main part 41 and the supporting part 42 may be other possible materials, and the material of the chain main part 41 and the supporting part 42 is not limited in the embodiment of the present application.
