According to the embodiment of the electronic device 100 provided by the application, the electronic device comprises a supporting structure 102, a flexible screen 104 and a telescopic assembly 106, wherein the flexible screen 104 is attached to the supporting structure 102 and supported by a first supporting piece 1022 and a second supporting piece 1024, so that the flatness of display is improved, the possibility of local deformation is reduced, and a certain display effect is ensured. Wherein a cavity is provided within support structure 102 to facilitate storage of flexible screen 104 when retracted, and also to facilitate providing space for retraction assembly 106 through the cavity.

Specifically, as shown in fig. 4, the telescopic assembly 106 mainly includes a telescopic member 1060 and a top screen member 1070, the top screen member 1070 can move relative to the telescopic member 1060, and since one end of the flexible screen 104 is connected to the second support member 1024, the second support member 1024 can be used as a moving end and can move relative to the fixed end of the first support member 1022, and on the basis, by connecting one end of the top screen member 1070 to one of the first support member 1022 and the second support member 1024, the flexible screen 104 can be indirectly driven to extend or retract under the action of the second support member 1024 when the top screen member 1070 moves relative to the telescopic member 1060.

The power-on state of the expansion piece 1060 of the flexible screen 104 in the expansion state is limited, and the power-on state of the expansion piece 1060 of the flexible screen 104 in the contraction state is different from the power-on state of the expansion piece 1060 of the flexible screen 104, so that the expansion and contraction of the flexible screen 104 can be realized when the expansion piece 1060 is in different power-on states, and it needs to be emphasized that the expansion piece 1060 can expand and contract, and the path of the top screen moving on the expansion piece 1060 can be changed, so that the expansion and contraction amplitude of the flexible screen 104 can be greatly improved, and the use experience of a user is improved.

It should be emphasized that the range of motion of the telescoping member when energized is different from the range of motion when de-energized, so that the maximum telescoping dimension of the flexible screen, i.e. the maximum distance the telescoping member can move, can be adjusted when the telescoping member is in different energized states.

In one particular embodiment, the telescoping member has a greater range of motion when energized and a lesser range of motion when not energized.

The extensible member 1060 mainly includes a fixing portion 1062 and a deformation portion 1064 connected to the fixing portion 1062, the size of the fixing portion 1062 is relatively constant, one end of the deformation portion 1064 is connected to the fixing portion 1062, the deformation portion 1064 is composed of a fitting housing 1066 and a deformable member 1068 disposed in the fitting housing 1066, and the size change of the entire extensible member 1060 is mainly realized by different shapes of the deformable member 1068 under two conditions of power-on and power-off.

It should be noted that, the shape of the deformable member 1068 that is powered on and powered off may be changed such that the size of the deformable member 1068 in the moving direction of the flexible screen 104 when powered on is larger than the size when powered off, or the size of the deformable member 1068 in the moving direction of the flexible screen 104 when powered on is smaller than the size when powered off, as long as it is ensured that there is a difference in size.

Fig. 5 shows a shape of the deformable member 1068 in a power-off state, and fig. 6 shows a shape of the deformable member 1068 in a power-on state.

The material of the matching shell 1066 may be rubber, soft plastic, or other materials with certain rigidity and deformability.

Further, as shown in fig. 3, the outer surface of the fixing portion 1062 is provided with a first tooth portion, the outer surface of the mating shell 1066 is provided with a second tooth portion, and the top screen 1070 specifically includes: a mating gear 1072, an inner surface of the mating gear 1072 being provided with a third tooth portion; and a follower lever 1074 having one end connected to the mating gear 1072 and the other end connected to the first support 1022 or the second support 1024, wherein the first, second, and third tooth parts have the same module.

By providing the first tooth portion and the second tooth portion on the outer surfaces of the fixing portion 1062 and the mating shell 1066, the top screen 1070 can be respectively matched with the first tooth portion or the second tooth portion through the third tooth portion on the inner surface under the action of the mating gear 1072, so as to realize the movement of the mating gear 1072 on the fixing portion 1062 and the mating shell 1066, specifically, when the flexible screen 104 is in a contracted state, the mating gear 1072 is located on the fixing portion 1062, when the flexible screen 104 needs to be extended, the rotation of the telescopic member 1060 can enable the mating gear 1072 to continuously move outwards, and as the mating gear 1072 is connected with the driven rod 1074, the first support 1022 or the second support 1024 connected thereto can move back and forth under the action of the driven rod 1074, so as to realize the extension and extension of the flexible screen 104.

The position of the telescopic element 1060 is relatively fixed, so that when the telescopic element 1060 rotates, under the engagement action of the telescopic element 1060 and the fixed gear, the mating gear 1072 can move axially relative to the telescopic element 1060, so as to extend or retract the flexible screen 104.

It should be noted that the third tooth portion needs to be engaged with the first tooth portion and the second tooth portion, respectively, and therefore the modulus of the third tooth portion and the second tooth portion need to be the same.

It will be appreciated that the connection between the first and third teeth is a mesh and the connection between the second and third teeth is a mesh.

In a specific embodiment, as shown in fig. 7, 8 and 9, during the unfolding process of the flexible screen 104, the deforming pieces 1068 are not powered, and as shown in fig. 7, the flexible screen 104 is in a wave state, the engaging gear 1072 is moved to one end of the fixing portion 1062 away from the driving member 108, at this time, one or more of the deforming pieces 1068 adjacent to the engaging gear 1072 is powered on to straighten the same, so that the engaging gear 1072 can continue to move rightward, as shown in fig. 8, the unfolding amplitude of the flexible screen 104 is extended, on the basis of which, if it is still necessary to increase the unfolding amplitude of the flexible screen 104, the corresponding deforming piece 1068 can continue to be controlled to be powered on, as shown in fig. 9, and finally, the engaging gear 1072 can be moved to the rightmost end, at this time, the unfolding amplitude of the flexible screen 104 is the largest.

Further, when the deformable member 1068 is energized, the extending direction of the fixed portion 1062 and the extending direction of the deformable portion 1064 are collinear, and in the moving direction of the flexible screen 104, the size of the deformable member 1068 when not energized is smaller than the size of the deformable member 1068 when energized.

When the deformation piece 1068 is electrified, the extending directions of the fixing portion 1062 and the deformation portion 1064 are the same and collinear, so that the matching gear 1072 can be smoothly matched with the deformation portion 1064 after passing through the fixing portion 1062, on the basis, the size of the deformation piece 1068 in the moving direction of the flexible screen 104 is smaller than that of the deformation piece 1064 when the flexible screen is not electrified, the deformation piece 1068 is not required to be electrified when the flexible screen contracts, and the deformation piece 1068 is only required to be electrified when the screen is required to be stretched out.

Further, when the deformation piece 1068 is electrified, the deformation piece 1068 is in a linear shape; when the deformation element 1068 is not electrified, the deformation element 1068 is in a curve shape.

Since the shape of the deformation restricting member 1068 is linear when it is energized and curved when it is not energized, its dimension in the moving direction of the flexible panel is small because it is curved when it is not energized. When the plurality of deforming pieces 1068 are provided, the shape of the entire deforming part can be changed by simultaneously changing the shape of the plurality of deforming pieces 1068. It should be emphasized that the deformation part 1068 is also linear when it is energized, and may be wavy or in the shape of a large arc when it is not energized.

Further, the number of the deforming pieces 1068 is plural, and one end of the fixing portion 1062 is connected to the deforming portion 1064 through one deforming piece 1068.

Generally, the electronic device is strictly used for a space, and by providing a plurality of deformable members 1068, the amount of expansion and contraction of the flexible screen 104 in the moving direction can be increased as much as possible in a limited space, and the overlapping property of the space can be better utilized, and in addition, one end of the fixed portion 1062 connected with the deformable portion 1064 is connected with one deformable member 1068 first, and the amount of expansion and contraction of the flexible screen 104 can be increased as well.

Through setting up the driving piece 108 with extensible member 1060 transmission connection, accessible electrically controlled mode drive extensible member 1060 rotates, on the pivoted basis of extensible member 1060, because the position of extensible member 1060 is comparatively fixed, so can make the relative axial displacement take place for the cooperation gear 1072 with it meshing to make flexible screen 104 can be normal stretch out and retract.

Further, still include: and the controller 110 is electrically connected with the driving member 108 and the deforming pieces 1068, and the controller 110 is used for controlling the operation of the driving member 108 and the on-off of each deforming piece 1068.

By providing the controller 110 electrically connected to the driving member 108 and the deforming member 1068, the operation of the driving member 108 and the deforming member 1068 can be controlled under the action of the controller 110, specifically, the driving member 108 is controlled to rotate the telescopic member 1060 forward or backward to achieve the extension or retraction of the flexible screen 104, and the deformation member 1068 is controlled to be powered on or powered off to achieve the change of the shape of the deforming portion 1064.

As shown in fig. 7 to 9, when the controller 110 controls the driving element 108 and the deforming element 1068 to operate, the method specifically includes: the driving member 108 is controlled to rotate to drive the telescopic member 1060 to rotate, so that the matching gear 1072 axially moves, the matching gear 1072 is connected with the driven rod 1074, when the matching gear 1072 moves outwards, the driven rod 1074 can eject the flexible screen 104, when the matching gear 1072 moves to the tail end of the fixing portion 1062, the controller 110 can control the adjacent deformation piece 1068 to be electrified, the shape of the matching shell 1066 outside the deformation piece 1068 is adjusted, so that the matching gear 1072 can smoothly move to the matching shell 1066, when the matching shell 1066 at the next section is moved, the controller 110 can control the corresponding deformation piece 1068 to be electrified, and the rest can be done in the same way, and the extension of the track is realized.
