Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1 to 11, an embodiment of the present application discloses an electronic device including a flexible screen 200, a frame assembly 100, and a driving assembly 300.
The flexible screen 200 is a display component of the electronic device, and the flexible screen 200 can be used for users to browse information and operate the electronic device. Optionally, the flexible screen 200 may be unfolded or folded to adjust the area of the display area 210, and when a user has a larger screen requirement, the flexible screen 200 is unfolded to provide the user with a larger display area 210, so as to facilitate browsing and operation of the user; when a user has a small screen requirement or carries, the flexible screen 200 is folded, so that the overall size of the electronic equipment is reduced, and the electronic equipment is convenient to carry.
The frame assembly 100 is a basic component of the electronic device, and the flexible screen 200 may be located inside the frame assembly 100, and the flexible screen 200 may be supported and protected by the frame assembly 100. The frame assembly 100 includes a first frame 110 and a second frame 120, with the first frame 110 and the second frame 120 being disposed for relative movement therebetween. In this way, the flexible screen 200 can be driven to be unfolded or folded by the relative movement of the first frame 110 and the second frame 120, so as to adjust the display area of the flexible screen 200. Alternatively, the first frame 110 may be a concave frame structure, and the second frame 120 may be a concave frame structure. In this way, after the first frame 110 and the second frame 120 are assembled with each other, a receiving space is defined therebetween, and the flexible screen 200 may be at least partially disposed between the first frame 110 and the second frame 120. Considering that the flexible screen 200 needs to be unfolded or folded, in the embodiment of the present application, one end of the flexible screen 200 is fixed to the second frame 120, the other end of the flexible screen 200 is movable relative to the second frame 120, and the other end of the flexible screen 200 may be disposed on the first frame 110 and movable relative to the first frame 110.
When a larger flexible screen 200 is needed, the first frame 110 and the second frame 120 are relatively far away, and at this time, the second frame 120 synchronously pulls one end of the flexible screen 200 away from the first frame 110, so that the flexible screen 200 is unfolded, a larger display area 210 is provided for a user, and user experience is improved; when the flexible screen 200 is required to be small or carried, the first frame 110 and the second frame 120 are relatively close to each other, and at this time, the flexible screen 200 can be folded to reduce the area, so that the portable electronic device is convenient for a user to carry.
It should be noted that, in order to enable the flexible screen 200 to be folded more smoothly, a power source may be added, for example, a traction structure is provided at the other end of the flexible screen 200 to draw the other end of the flexible screen 200 when the first frame 110 and the second frame 120 are relatively close together, so that a portion of the flexible screen 200 enters the frame assembly 100 and the display area 210 of the flexible screen 200 is correspondingly reduced. In addition, when the other end of the flexible screen 200 is wound on the winding device, the flexible screen 200 can be wound by the winding device, so that the other end of the flexible screen 200 can be pulled when the first frame 110 and the second frame 120 are relatively close to each other, so that part of the flexible screen 200 enters the frame assembly 100 to correspondingly reduce the display area 210 of the flexible screen 200. The folding manner of the flexible screen 200 is not limited in the embodiment of the present application, as long as the flexible screen 200 can be folded smoothly.
In order to realize the relative movement between the first frame 110 and the second frame 120, a driving assembly 300 is added in the embodiment of the present application. Specifically, a first cavity 1111 is provided on the first frame 110, and a second cavity 1211 is provided on the second frame 120. Alternatively, a first cavity 1111 is opened on an end surface of the first frame 110 opposite to the second frame 120, and correspondingly, a second cavity 1211 is opened on an end surface of the second frame 120 opposite to the first frame 110. In this way, when the first frame 110 is not separated from the second frame 120, the first cavity 1111 and the second cavity 1211 together enclose an entire cavity, so that an installation space for the driving assembly 300 can be provided.
The driving assembly 300 includes a flexible printed member 310 and an electro-deformable member 320, wherein one end of the flexible printed member 310 is connected to the first frame 110 and the other end is connected to the second frame 120. Alternatively, a part of the flexible printed unit 310 is located in the first cavity 1111 and is fixedly connected to the bottom end surface of the first cavity 1111, and another part is located in the second cavity 1211 and is fixedly connected to the bottom end surface of the second cavity 1211. In addition, the flexible printed member 310 may be a folded flexible printed board having scalability so that it can accommodate relative movement between the first frame 110 and the second frame 120. The electro-deformation element 320 is disposed on the flexible printed board, the electro-deformation element 320 is a structural member capable of being deformed under the condition of electrification, and the deformation modes of the electro-deformation element 320 are different according to different electrification conditions. For example, when a positive voltage is applied to the electro-deformation element 320, the electro-deformation element may bend and deform toward one side, when a negative voltage is applied, the electro-deformation element 320 may bend and deform toward the other side, and may return to an initial state when the electro-deformation element 320 is powered off, and the degree of deformation may be determined according to the magnitude of the applied voltage. The electro-deformation element 320 is disposed on the flexible printed element 310, and can drive the flexible printed element 310 to stretch or shorten when the electro-deformation element 320 deforms, so that the flexible printed element 310 drives the first frame 110 and the second frame 120 to move relatively. The specific principles of the electro-deformation element 320, and the specific structure and principles of the flexible printed element 310, are described herein, and are not described in detail in the related art.
In the embodiment of the present application, when the electro-deformation element 320 is energized, the electro-deformation element 320 deforms and drives the flexible printed element 310 to extend or retract, and as the two ends of the flexible printed element 310 are respectively connected with the first frame 110 and the second frame 120, the flexible printed element 310 drives the first frame 110 and the second frame 120 to be relatively far away or relatively close, and the first frame 110 and the second frame 120 relatively move to realize the expansion or retraction of the flexible screen 200.
Based on the above arrangement, when a user is demanding a larger display screen, a first form of voltage can be applied to deform the electro-deformation element 320 towards the first direction, the electro-deformation element 320 drives the flexible printed element 310 to extend, and the flexible printed element 310 drives the first frame 110 and the second frame 120 to be relatively far away, so that the flexible screen 200 is unfolded, and the display area of the flexible screen 200 is enlarged; when a user needs a smaller display screen or carries the display screen, a voltage of a second form can be introduced to deform the electro-deformation element 320 towards a second direction opposite to the first direction, the electro-deformation element 320 drives the flexible printed element 310 to shrink, and the flexible printed element 310 drives the first frame 110 and the second frame 120 to be relatively close to each other, so that the flexible screen 200 is folded, and the display area of the flexible screen 200 is reduced. Based on the above arrangement, compared with a conventional motor driving mode, the driving assembly 300 is simpler and smaller, the space occupied by the driving assembly 300 is reduced, and the influence on the layout of other electronic components in the electronic equipment is relieved.
Referring to fig. 8 and 10, in some embodiments, in order to achieve the relative movement between the first frame 110 and the second frame 120, a first guide 130 is provided on the first frame 110, and correspondingly, a second guide 140 is provided on the second frame 120, and the relative movement between the first frame 110 and the second frame 120 may be achieved by slidably connecting the first guide 130 and the second guide 140.
In a more specific embodiment, the first guide 130 may be a first guide bar, and the second guide 140 may be a second guide bar, one end of the first guide bar being welded to the first frame 110 and extending toward the second frame 120, and one end of the second guide bar being welded to the second frame 120 and extending toward the first frame 110. In order to enable the first guide rod and the second guide rod to slide relatively, a hole site can be formed on the first guide rod along the length direction of the first guide rod to form a guide channel 131, and the second guide rod part is penetrated in the guide channel 131 of the first guide rod and can move in the guide channel 131. Of course, a hole may be formed in the second guide rod along the length direction thereof to form the guide channel 131, and the first guide rod portion is disposed through the guide channel 131 of the second guide rod and is movable in the guide channel 131. In this manner, a relatively distant or relatively close between the first frame 110 and the second frame 120 is achieved by the movable connection between the first and second guide bars. In addition, a guide rail may be provided on the first frame 110 or the second frame 120 so that the two are slidably connected through the guide rail, and a relative distance or a relative approach between the first frame 110 and the second frame 120 may be achieved. The sliding fit manner between the first frame 110 and the second frame 120 is not limited in the embodiment of the present application.
In some embodiments, the first frame 110 includes first frame portions 111 disposed at both sides of the flexible screen 200, respectively, and a housing portion 112 connecting the first frame portions 111 at both sides, as shown in fig. 2 and 3. The first frame portions 111 and the housing portions 112 on both sides form a concave frame structure, so that a part of the flexible screen 200 can be surrounded to limit and protect the flexible screen 200. Optionally, at least one first cavity 1111 is defined on the first frame portion 111 on each side, comprising: one, two, three, five, etc., the number of the first cavities 1111 in the first frame portion 111 is not limited in the embodiment of the present application.
The second frame 120 includes second frame portions 121 provided at both sides of the flexible screen 200, respectively, and connection portions 122 connecting the second frame portions 121 at both sides, as shown in fig. 2 and 3. The second frame parts 121 and the connecting parts 122 on two sides form a concave frame structure, so that the other part of the flexible screen 200 can be surrounded to limit and protect the flexible screen 200. Optionally, at least one second cavity 1211 is defined on the second frame portion 121 on each side, including: one, two, three, five, etc., the number of the second cavities 1211 on the second frame part 121 is not limited in the embodiment of the present application.
In the embodiment of the present application, the number of the first cavities 1111 on the first frame portion 111 is equal to the number of the second cavities 1211 on the second frame portion 121, and the first cavities 1111 are disposed corresponding to the second cavities 1211, so that the driving assembly 300 can be commonly accommodated.
Based on the above arrangement, when the first frame 110 is not separated from the second frame 120, a part of the flexible screen 200 is received inside the frame assembly 100 and another part of the flexible screen 200 is displayed outside for the user to browse and operate. Alternatively, the flexible screen 200 includes a first end and a second end disposed opposite to each other, the first end being movably disposed on the second frame 120, and the second end being fixed to the connection portion 122.
Referring to fig. 4 and 6, in some embodiments, the flexible screen 200 may include a display area 210 and a hidden area 220, wherein the display area 210 is a portion exposed outside the frame assembly 100 for a user to view or manipulate, and the hidden area 220 is a portion located inside the frame assembly 100. When the flexible screen 200 is unfolded, the hidden portion is partially removed from the inside of the frame assembly 100 to become the display area 210, so that the area of the display area 210 can be increased; when the flexible screen 200 is folded, a portion of the display area 210 moves from the outside of the frame assembly 100 to the inside of the frame assembly 100 to become a hidden area 220, so that the area of the display area 210 can be reduced. Typically, the display area 210 is located at an upper layer of the frame assembly 100 and the hidden area 220 is located at a lower or middle layer of the frame assembly 100. The middle portion of the flexible screen 200 may be provided with a support structure, such as a shaft-like member, on which the flexible screen 200 is wound, and through which the flexible screen 200 may be bent, curled, etc., so that the flexible screen 200 appears as a display area 210 located at the upper layer of the frame assembly 100 and a hidden area 220 located at the lower or middle layer of the frame assembly 100.
In order to facilitate the unfolding or folding of the flexible screen 200, in the embodiment of the application, a rolling shaft 400 and a supporting rod 500 are added, the rolling shaft 400 is rotatably arranged in the shell part 112, the middle area of the flexible screen 200 is wound on the rolling shaft 400, and when the flexible screen 200 is unfolded or folded, the rolling shaft 400 can rotate relative to the shell part 112, so that a certain dredging effect is played on the flexible screen 200, the moving resistance of the flexible screen 200 is reduced, and the moving smoothness of the flexible screen 200 is improved. The support bar 500 is movably disposed on the second frame part 121, the first end of the flexible screen 200 is connected to the support bar 500, and when the first frame 110 is relatively far from the second frame 120, the second end of the flexible screen 200 moves along with the connection part 122 in a direction away from the first frame 110, and the first end of the flexible screen 200 pulls the support bar 500 to move in a direction approaching the first frame 110 relative to the second frame 120, so that the area of the display area 210 of the flexible screen 200 can be adjusted. When the first frame 110 and the second frame 120 are relatively close, the support rod 500 moves on the second frame 120 towards a direction away from the first frame 110, and the first end of the flexible screen 200 is pulled by the support rod 500, so that more flexible screens 200 are pulled into the frame assembly 100 to adapt to the relatively close of the first frame 110 and the second frame 120, and therefore, the problems of wrinkling, curling and the like of the flexible screen 200 can be effectively prevented.
Further, in order to drive the movement of the support bar 500 with respect to the second frame 120, another driving assembly 300 is provided between the support bar 500 and the connection part 122, and the support bar 500 can be driven to move with respect to the second frame 120 by the driving assembly 300. Alternatively, the driving assembly 300 has the same structure and operation principle as the driving assembly 300 driving the first and second frames 110 and 120, and includes a flexible printed unit 310 and an electro-deformation unit 320 disposed on the flexible printed unit 310, wherein one end of the flexible printed unit 310 is connected to the support bar 500, and the other end is connected to the connection part 122. In this way, when the first frame 110 and the second frame 120 are relatively far away, the driving assembly 300 disposed in the first cavity 1111 and the second cavity 1211 contracts to provide traction force, the connection portion 122 on the second frame 120 synchronously drives the second end of the flexible screen 200 to move away from the first frame 110, the middle portion of the flexible screen 200 is supported by the rolling shaft 400 and drives the rolling shaft 400 to rotate, the first end of the flexible screen 200 pulls the supporting rod 500 to move towards the direction approaching the first frame 110 relative to the second frame 120, and at the same time, the driving assembly 300 connected between the supporting rod 500 and the fixing portion extends, so that interference is not generated in the unfolding process of the flexible screen 200, and the hidden area 220 located in the frame assembly 100 is partially moved out and converted into the display area 210, so that the display area of the flexible screen 200 is increased. When the first frame 110 and the second frame 120 are relatively close, the driving assembly 300 disposed in the first cavity 1111 and the second cavity 1211 is extended to provide a pushing force, the connection part 122 on the second frame 120 simultaneously drives the second end of the flexible screen 200 to move toward the direction approaching the first frame 110, at this time, the driving assembly 300 connected between the support bar 500 and the fixing part is contracted and applies a traction force to the support bar 500, at the same time, the driving assembly 300 disposed in the first cavity 1111 and the second cavity 1211 is contracted, thereby not interfering with the folding process of the flexible screen 200, the first end of the flexible screen 200 is moved away from the first frame 110 along with the support bar 500 moving toward the direction away from the first frame 110 relative to the second frame 120, so that the display area 210 disposed outside the frame assembly 100 is partially moved into the frame assembly 100 to be converted into the hidden area 220, and the display area of the flexible screen 200 is reduced.
Based on the above arrangement, through the mutual cooperation of the two sets of driving assemblies 300, the first frame 110 and the second frame 120 can be far away from or close to each other, and the flexible screen 200 can be unfolded or folded along with the relative movement between the first frame 110 and the second frame 120, so as to meet different requirements of users. It should be noted that, during the deployment of the flexible screen 200, the driving assemblies 300 located in the first and second cavities 1111 and 1211 are elongated, and the driving assemblies 300 connected between the support bar 500 and the fixing portion are elongated; during the folding of the flexible screen 200, the driving assembly 300 positioned in the first and second chambers 1111 and 1211 is contracted, and the driving assembly 300 connected between the support bar 500 and the fixing portion is contracted.
Referring to fig. 8 and 10, in some embodiments, the second frame portion 121 is provided with a sliding portion 1212, the sliding portion 1212 extends along a first direction parallel to a direction in which the first frame 110 and the second frame 120 move relative to each other, and the support rod 500 is slidably connected to the sliding portion 1212. Alternatively, the sliding portion 1212 may be a sliding groove, a sliding rail, or the like, and two ends of the supporting rod 500 are respectively slidably connected with the sliding portions 1212 on the first frame portions 111 on two sides, so as to ensure that the flexible screen 200 is more stable and smooth in the unfolding or folding process.
In other embodiments, the electronic device may further include a take-up shaft (not shown) rotatably disposed inside the housing portion 112. Alternatively, the winding shaft may include a driving motor as a power source for rotation of the winding shaft, the winding shaft is driven to rotate by the driving motor, and the first end of the flexible screen 200 is pulled by the winding shaft to wind the flexible screen 200 when the first frame 110 and the second frame 120 are relatively close to each other, so as to prevent the flexible screen 200 from being wrinkled or curled. It should be noted that, the speed of winding the flexible screen 200 by the winding shaft is equal to the speed of relatively approaching the first frame 110 and the second frame 120, so as to prevent the winding action of the flexible screen 200 and the relatively approaching action of the two frames from interfering with each other.
In some embodiments, the electronic device has a first side and a second side disposed opposite each other. Alternatively, the first side and the second side are spaced apart along the thickness direction of the electronic device. The flexible screen 200 includes a first end and a second end disposed opposite one another. It will be appreciated that the first and second ends are disposed along the direction of deployment or deployment of the flexible screen 200. The second end of the flexible screen 200 is fixedly connected with the area of the second frame 120 located at the first side, and the first end of the flexible screen 200 is wound from the first side to the second side and extends towards a direction away from the first housing 110. It is understood that the first side is an upper side of the electronic device in the thickness direction and the second side is a lower side of the electronic device in the thickness direction, and thus the flexible screen 200 is folded back from the upper side of the electronic device to the lower side of the electronic device through the first frame 110.
Based on the above arrangement, in the case where the first frame 110 is folded with respect to the second frame 120, the first end of the flexible screen 200 is located at the end of the second frame 120 away from the first frame 110, and in the case where the first frame 110 is unfolded with respect to the second frame 120, the first end of the flexible screen 200 is located at the end of the second frame 120 adjacent to the first frame 110. It will be appreciated herein that, during the process of relatively folding the first frame 110 and the second frame 120, as the flexible screen 200 moves, the portion of the flexible screen 200 located on the upper side of the electronic device moves into the frame assembly 100, thereby reducing the display area of the flexible screen 200. During the relative unfolding of the first frame 110 and the second frame 120, the portion of the flexible screen 200 located at the lower side of the electronic device moves out of the frame assembly 100 as the flexible screen 200 moves, thereby increasing the display area of the flexible screen 200. The first end is located at an end of the second frame 120 away from the first frame 110, and is not limited to the end of the second frame 120, and may include a region near the end; likewise, the first end is located at an end of the second frame 120 adjacent to the first frame 110, and is not limited to the end of the second frame 120, and may include a region near the end.
In some embodiments, the flexible printed circuit 310 may be a foldable FPC (Flexible Printed Circuit), and the FPC is a flexible printed circuit board, which is made of polyimide or mylar, and has high reliability, excellent flexibility, high wiring density, light weight, thin thickness, and good flexibility. Based on this, when the electro-deformation member 320 is energized, the foldable FPC may be driven to be elongated or contracted to change the length of the flexible printed member, thereby driving the first frame 110 to be relatively far away from or relatively close to the second frame 120 by the flexible printed member, or driving the support member to be moved relative to the second frame 120.
Further, referring to fig. 11, the flexible printed circuit 310 includes valley regions 311 and valley regions 312 that are periodically and alternately arranged, and the electro-deformation element 320 is connected between adjacent valley regions 311. When the electro-deformation element 320 is energized, the two adjacent sets of valley and peak regions 311 can be driven away from or toward each other, so that the length of the flexible printed element 310 can be changed. Optionally, a plurality of electro-deformation elements 320 disposed side by side are connected between each two adjacent sets of valley-peak regions 311, so as to ensure that the flexible printed element 310 stretches more uniformly around the direction perpendicular to the stretching direction. In addition, the electro-deformation member 320 may be fixed to the valley region 311 by welding.
The electronic device in the embodiment of the application can be a mobile phone, a tablet personal computer, an electronic book reader, a wearable device, a vehicle-mounted device, an unmanned aerial vehicle device and the like, and the embodiment of the application is not limited to the specific type of the electronic device.
In summary, the electronic device disclosed in the embodiment of the present application does not adopt motor driving, so that the whole electronic device has a simple structure and a reduced volume, and when there is a display requirement of playing games, watching video and other comprehensive screens, the flexible screen 200 can be unfolded, so as to realize larger-area screen display, thereby improving experience of users such as extreme games and video and audio; when the electronic device is required to be carried and reduced in size, the flexible screen 200 can be folded, so that the purposes of reducing the size and being convenient to carry are achieved.
