The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 15, an electronic device provided in an embodiment of the present application includes: a flexible screen 100, a driving mechanism 200 and an elastic connector 300; the driving mechanism 200 comprises a driving assembly and a driven member 201, wherein the driven member 201 is positioned on the non-display end surface side of the flexible screen 100; a first end of the elastic connecting member 300 is connected with the follower 201, and a second end of the elastic connecting member 300 is connected with the flexible screen 100; wherein, in the process of the flexible screen 100 transforming from the unfolded state to the folded state, the driving assembly drives the driven member 201 to move in the direction away from the flexible screen 100, and the elastic connecting member 300 transforms from the compressed state to the stretched state; in the process of converting the flexible screen 100 from the folded state to the unfolded state, the driving assembly drives the driven member 201 to move in a direction close to the flexible screen 100, and the elastic connecting member 300 is converted from the stretched state to the compressed state.
The flexible screen 100 includes a display end surface and a non-display end surface, where the non-display end surface may be an end surface opposite to the display end surface, and the display end surface is used for displaying data, such as displaying images and displaying characters.
The driven member 201 may also be a connecting member, and is configured to connect the first end of the elastic connecting member 300 and the motion output end of the driving assembly, so that the driving assembly moves and drives the elastic connecting member 300 to perform a telescopic motion, and further the elastic connecting member 300 can be changed between a telescopic state and a stretching state.
The driving assembly may be connected to the flexible screen 100 through a transmission member, so that the driving assembly can move under the driving of the flexible screen 100. Specifically, in the process of folding flexible screen 100, the driving medium can transmit the rotary motion of flexible screen 100 to the drive assembly, and then the drive assembly converts the received rotary motion into linear motion, thereby driving follower 201 to move towards or away from flexible screen 100, and then realizing the technical effect that elastic connection member 300 can change between the telescopic state and the stretching state. In addition, the transmission member may convert the received rotational movement of the flexible screen 100 into other types of movement, and then transmit the movement to the driving assembly.
Of course, the driving assembly may also independently drive the driven member 201 to move, and in this case, the driving assembly may be a common structure capable of outputting a telescopic motion, and may be, for example, a linear motor, a crank-slider mechanism, a cam-link mechanism, or the like. Specifically, a detection element may be configured to detect a rotation angle of the flexible screen 100, and when the rotation angle is greater than a preset value, it is determined that the flexible screen 100 is folded or unfolded, and at this time, the detected signal is transmitted to a control unit of the electronic device, and the control unit controls the driving assembly to operate, so as to drive the driven member 201 to move toward or away from the flexible screen 100. Wherein, whether the flexible screen 100 is to be unfolded or folded can be determined by detecting whether the angle of rotation of the flexible screen 100 is increased or decreased. When the angle of the flexible screen 100 is increased and the rotation angle is greater than the preset value, it is determined that the flexible screen 100 is unfolded, and at this time, the driven member 201 is driven by a driving assembly to move towards the flexible screen 100; on the contrary, when the angle of the flexible screen 100 is decreased and the rotation angle is greater than the preset value, it is determined that the flexible screen 100 is folded, and at this time, the driven member 201 is driven by the driving assembly to move away from the flexible screen 100.
Alternatively, the follower 201 may be disposed opposite to the folding line when the folding screen is in the folded state, and the second end of the elastic connection member 300 may be connected to a position close to the folding line, so that the follower 201 stretches a redundant portion of the folding line position of the flexible screen 100 to the outside in the process of converting the flexible screen 100 from the unfolded state to the folded state, thereby preventing the problem that the folding line position is layered or creased due to local redundancy.
In addition, the elastic connection member 300 may be a spring. Thus, when the elastic connection member 300 is in a stretched state, an outward tensile force can be provided to the flexible screen 100 due to the elastic force of the elastic connection member 300.
In this embodiment, in the process of folding the flexible screen 100, the driving assembly drives the follower 201 to move away from the flexible screen 100, so that the elastic connecting member 300 is changed from a compression state to a tension state, that is, when the flexible screen 100 is in a folded state, the elastic connecting member 300 is in the tension state, and thus, under the action of the tensile force of the elastic connecting member 300, the redundant part of the folded position of the flexible screen 100 is stretched, thereby effectively relieving the problem of damage to the folded screen due to the layering phenomenon occurring at the folded position in the process of folding the flexible screen 100. In addition, when the flexible screen 100 is in the unfolded state, the elastic connecting member 300 is in the stretched state, and at this time, the elastic connecting member 300 can effectively support the flexible screen 100, so that the flexible screen 100 is prevented from being automatically folded under the action of self gravity.
Optionally, the follower 201 includes an elastic carrier plate, a first end of the elastic connecting member 300 is connected to a side of the elastic carrier plate facing the flexible screen 100, and the driving assembly is connected to a side of the elastic carrier plate facing away from the flexible screen 100;
in the process of folding or unfolding the flexible screen 100, the driving assembly drives the elastic carrier plate to switch between the first deformation state and the second deformation state, and the elastic connecting member 300 switches between the compression state and the extension state.
The elastic carrier plate may be a common elastic plate body, for example, a steel plate, a copper plate, an elastic plastic plate, or the like. Above-mentioned elastic carrier plate can with electronic equipment's shell connection, for example, can the inside of casing sets up two spliced poles to with the both ends of elastic carrier plate fixed connection respectively in two the spliced pole, wherein, can with two the distance of spliced pole sets up to being less than elastic connecting plate's length, like this, work as when elastic connecting plate's both ends are fixed in two spliced poles, elastic connecting plate will have two kinds of deformation states, and the deformation state of encircleing towards flexible screen 100 promptly and the state of encircleing flexible screen 100 dorsad, these two kinds of deformation states can do respectively first deformation state and second deformation state. For convenience of description, a deformation state in which the elastic connection plate is arched toward the flexible screen 100 is referred to as the first deformation state, and a deformation state in which the elastic connection plate is arched away from the flexible screen 100 is referred to as the second deformation state. The elastic carrier plate can be switched between the first deformation state and the second deformation state by pushing or pulling the elastic carrier plate through the driving assembly, so that the elastic connecting piece 300 is switched between the compression state and the extension state.
Optionally, the flexible screen 100 comprises a first portion and a second portion, the first portion and the second portion being symmetrically distributed about a first axis of symmetry about which at least one of the first portion and the second portion rotates during folding or unfolding of the flexible screen 100;
the electronic device comprises a plurality of the elastic connecting pieces 300, and the plurality of the elastic connecting pieces 300 are symmetrically arranged about the first symmetry axis.
Wherein, first symmetry axis can be flexible screen 100 is to broken line when fold condition the in-process that the elasticity support plate switches between first deformation state and second deformation state, and is a plurality of equal simultaneous movement of elastic connection 300 just keeps the same elastic state all the time. Specifically, when the elastic carrier is in the first deformation state, each elastic connecting element 300 is in a compressed state, whereas when the elastic carrier is in the second deformation state, each elastic connecting element 300 is in a stretched state.
In this embodiment, the plurality of elastic connectors 300 are symmetrically arranged about the pair of folding lines, so that when the flexible screen 100 is in the folded state, the flexible screen 100 is stretched outward from different directions by the elastic connectors 300, and the flexible screen 100 is stretched at the position of the pair of folding lines by the elastic force of the elastic connectors 300 to form the shape shown in fig. 3. Because the position of the folding line is expanded, the phenomenon that the position of the folding line is layered in the process of folding the flexible screen 100 is avoided. In addition, because the position of the folding line is unfolded, the screen on two sides of the folding line is also prevented from being folded along the folding line directly to form a crease, and the phenomenon of layering of the position of the folding line is further avoided.
Optionally, the plurality of elastic connection members 300 includes at least two elastic connection members 300 with different free lengths, and the free lengths of the elastic connection members 300 are gradually increased along a direction away from the first symmetry axis, wherein the free length of the elastic connection member 300 is the length of the elastic connection member 300 in a free state.
The length of the elastic connection member 300 in the free state may refer to a length of the elastic connection member 300 when it is not applied by an external force.
When the follower 201 is an elastic carrier plate, please refer to fig. 6, since the elastic carrier plate is arched from the middle, when the flexible screen 100 is in the unfolded state, distances between positions of the elastic carrier plate and the flexible screen 100 are different. Therefore, in order to ensure that the supporting force of the flexible screen 100 by the elastic connection members 300 at each position is relatively uniform, the length of the elastic connection members 300 can be determined by connecting the elastic connection members 300 with different free lengths at different positions of the elastic carrier plate, for example, according to the distance between the position where each elastic connection member 300 is connected to the flexible screen 100 and the first symmetry axis, and the elastic connection members 300 are selected to be relatively longer as the connection position is farther from the first symmetry axis.
It should be noted that, since the plurality of elastic connection members 300 are symmetrical about the first symmetry axis, the free lengths of the elastic connection members 300 at the symmetrical positions of the first symmetry axis may be the same, thereby further ensuring that the supporting force of the elastic connection members 300 at both sides of the first symmetry axis to the flexible screen 100 is relatively uniform when the flexible screen 100 is in the unfolded state.
Optionally, the drive assembly comprises a drive shaft 204, a cam 202 and a link 203;

In addition, the second end of the connecting rod 203 may be rotatably connected to the elastic carrier plate through a third rotating shaft 205, specifically, a support for connecting to the third rotating shaft 205 may be disposed on a side of the elastic carrier plate away from the flexible screen 100, the third rotating shaft 205 may be rotatably connected to the support, and then the second end of the connecting rod 203 is connected to the third rotating shaft 205, that is, the second end of the connecting rod 203 and the elastic carrier plate may be rotatably connected.

In the process that the first rotating shaft 206 moves from the highest point to the lowest point, the elastic carrier gradually changes from the first elastic deformation state to the second elastic deformation state, and conversely, in the process that the first rotating shaft 206 moves from the lowest point to the highest point, the elastic carrier gradually changes from the second elastic deformation state to the first deformation state.

In addition, the first rigid support plate 600 and the second rigid support plate 700 attached to the flexible screen 100 are provided, so that the areas of the flexible screen 100 corresponding to the first rigid support plate 600 and the second rigid support plate 700 are always kept flat.

Referring to fig. 13, a connection state diagram of the first rigid support plate 600, the flexible support plate 102 and the second rigid support plate 700 when the flexible screen 100 is in the unfolded state is shown, at this time, because two ends of the flexible support plate 102 are respectively fixed to the first rigid support plate 600 and the second rigid support plate 700, and lower ends of two adjacent strip-shaped plates 701 are abutted, the flexible support plate 102 cannot continue to bend and deform upwards under the elastic force of the elastic connecting member 300, that is, the flexible support plate 102 cannot arch and deform upwards, thereby ensuring the flatness of the flexible screen 100 in the unfolded state. Since the second rotating shaft 702 between the two adjacent strip-shaped plates 701 is located at an end close to the flexible screen 100, in the process of folding the flexible screen 100, the two adjacent strip-shaped plates 701 can rotate around the second rotating shaft 702 between the two adjacent strip-shaped plates 701, so that the flexible support plate 102 is arched downwards to form the state shown in fig. 3.
In this embodiment, the flexible support plate 102 is configured as above, so that the flexible support plate 102 can only move to the horizontal state toward the flexible screen 100, and can move to the arched state away from the flexible screen 100. In this way, the flatness of the flexible screen 100 is ensured when the flexible screen 100 is in the unfolded state, and the flexible support plate 102 can be folded together with the flexible screen 100 during the folding process of the flexible screen 100. In addition, the first rigid support plate 600, the flexible support plate 102 and the second rigid support plate 700 are connected in sequence, so that the problem of poor support effect caused by the formation of a gap between the rigid support plate and the flexible support plate 102 is solved.
