It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 11, an electronic device is disclosed in an embodiment of the present application, and the disclosed electronic device includes 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 a user to browse information and operate the electronic device. Optionally, the flexible screen 200 may be expanded or collapsed to adjust the area of the display area 210, and when the user has a large screen demand, the flexible screen 200 is expanded to provide the user with a larger display area 210, so as to facilitate browsing and operation of the user; when the user has a smaller screen requirement or carries the electronic device, the flexible screen 200 is folded, so that the overall size of the electronic device is reduced, and the electronic device is convenient to carry.
The frame assembly 100 is a basic component of the electronic device, and the flexible screen 200 can be located inside the frame assembly 100, and the frame assembly 100 can support and protect the flexible screen 200. The frame assembly 100 includes a first frame 110 and a second frame 120, and the first frame 110 and the second frame 120 are movably disposed relative to each other. Thus, 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 also 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. In consideration of the requirement for the flexible screen 200 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, and the other end is movable relative to the second frame 120, while the other end of the flexible screen 200 may be disposed on the first frame 110 and movable relative to the first frame 110, and in addition, the other end of the flexible screen 200 may be wound on a winding device and disposed on the first frame 110, so that as the first frame 110 and the second frame 120 move relative to each other, one end of the flexible screen 200 moves with the second frame 120, and the other end may move relative to the first frame 110 or move relative to the winding device, thereby adapting the flexible screen 200 to the relative movement between the first frame 110 and the second frame 120.
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 to be far away from the first frame 110, so that the flexible screen 200 is unfolded to provide a larger display area 210 for a user, and the user experience is improved; when a smaller flexible screen 200 is needed or is 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 carrying by a user is facilitated.
It should be noted that, in order to enable the flexible screen 200 to be more smoothly folded, a power source may be added, for example, a traction structure may be provided at the other end of the flexible screen 200 to pull the other end of the flexible screen 200 when the first frame 110 and the second frame 120 are relatively close to each other, 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 rolled on the rolling device, the flexible screen 200 may be rolled by the rolling device, so that the other end of the flexible screen 200 may also be pulled when the first frame 110 and the second frame 120 are relatively close to each other, so that a portion of the flexible screen 200 enters the inside of the frame assembly 100 to correspondingly reduce the display area 210 of the flexible screen 200. In the embodiment of the present application, the folding manner of the flexible screen 200 is not limited, as long as the flexible screen 200 can be smoothly folded.
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, the first frame 110 is provided with a first cavity 1111, and the second frame 120 is provided with a second cavity 1211. Optionally, 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 and the second frame 120 are not separated, the first cavity 1111 and the second cavity 1211 together form a whole cavity, so that the installation space for the driving assembly 300 can be provided.
The driving assembly 300 includes a flexible printed member 310 and an electro-transformation 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. Optionally, a portion of the flexible printed object 310 is located in the first cavity 1111 and fixedly connected to the bottom end surface of the first cavity 1111, and another portion is located in the second cavity 1211 and fixedly connected to the bottom end surface of the second cavity 1211. In addition, the flexible printed 310 may be a folded flexible printed board having flexibility so as to accommodate relative movement between the first frame 110 and the second frame 120. The electro-deformable member 320 is disposed on the flexible printed board, the electro-deformable member 320 is a structural member that can deform under the power-on condition, and the deformation mode of the electro-deformable member 320 is different according to the power-on condition. For example, when a positive voltage is applied to the electro-deformable member 320, it can be bent and deformed towards one side, and when a negative voltage is applied, it can be bent and deformed towards the other side, and in case that the electro-deformable member 320 is powered off, it can be restored to the original state, and the deformation degree can be determined according to the magnitude of the applied voltage. The electro-deformable member 320 is disposed on the flexible printed member 310, and the flexible printed member 310 is driven to extend or contract when the electro-deformable member 320 is deformed, so that the flexible printed member 310 drives the first frame 110 and the second frame 120 to move relatively. It should be noted that, with regard to the specific principle of the electro-deformable member 320, and the specific structure and principle of the flexible printed member 310, reference is made to the related art, and the detailed description is not provided herein.
In the embodiment of the application, when the electro-deformable element 320 is energized, the electro-deformable element 320 is deformed, and the flexible printed element 310 is driven to extend or contract by the electro-deformable element 320, because 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 can drive the first frame 110 and the second frame 120 to be relatively far away from or relatively close to each other, and the first frame 110 and the second frame 120 move relatively to realize the expansion or the folding of the flexible screen 200.
Based on the above arrangement, when a user needs a larger display screen, a first form of voltage may be applied to deform the electro-deformable member 320 toward the first direction, the electro-deformable member 320 drives the flexible printed member 310 to extend, and the flexible printed member 310 drives the first frame 110 and the second frame 120 to move away from each other, so that the flexible screen 200 is unfolded, and the display area of the flexible screen 200 is enlarged; when the user needs a smaller display screen or carries the display screen, the user may apply a voltage of the second type to deform the electro-deformable member 320 toward a second direction opposite to the first direction, and the electro-deformable member 320 drives the flexible printed member 310 to contract, and the flexible printed member 310 drives the first frame 110 and the second frame 120 to approach each other relatively, so that the flexible screen 200 is folded, and the display area of the flexible screen 200 is reduced. Based on above-mentioned setting, compare in conventional motor drive mode, drive assembly 300 in this application is succinct more, small and exquisite, has reduced the shared space of drive assembly 300, has alleviated the influence to the overall arrangement of other electronic components in electronic equipment.
Referring to fig. 8 and 10, in some embodiments, in order to realize the relative movement between the first frame 110 and the second frame 120, a first guide 130 is disposed on the first frame 110, and correspondingly, a second guide 140 is disposed on the second frame 120, and the relative movement between the first frame 110 and the second frame 120 can be realized 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, the second guide 140 may be a second guide bar, one end of the first guide bar is welded to the first frame 110 and extends toward the second frame 120, and one end of the second guide bar is welded to the second frame 120 and extends toward the first frame 110. In order to make the first guide bar and the second guide bar slide relatively, a hole may be formed on the first guide bar along the length direction thereof to form a guide channel 131, and the second guide bar partially penetrates the guide channel 131 of the first guide bar and is movable in the guide channel 131. Of course, it is also possible to form the guide passage 131 by forming a hole on the second guide bar along the length direction thereof, and the first guide bar is partially inserted into the guide passage 131 of the second guide bar and is movable in the guide passage 131. As such, by the movable connection between the first guide bar and the second guide bar, the relative distance or the relative proximity between the first frame 110 and the second frame 120 is achieved. Besides, a guide rail may be disposed on the first frame 110 or the second frame 120, so that the two are slidably connected through the guide rail, and the first frame 110 and the second frame 120 may be relatively far away from each other or relatively close to each other. The sliding fit between the first frame 110 and the second frame 120 is not limited in the embodiments of the present application.
In some embodiments, the first frame 110 includes a first frame portion 111 disposed on each side of the flexible screen 200 and a housing portion 112 connecting the first frame portions 111 on each side, as shown in fig. 2 and 3. A concave frame structure is enclosed by the first frame part 111 and the housing part 112 on two sides, so that a part of the flexible screen 200 can be enclosed to limit and protect the flexible screen 200. Optionally, at least one first cavity 1111 is defined on the first frame section 111 of each side, comprising: one, two, three, five, etc., the number of first cavities 1111 on the first frame part 111 is not limited in the embodiment of the present application.
The second frame 120 portion includes a second frame portion 121 respectively disposed at both sides of the flexible screen 200 and a connecting portion 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 the two sides enclose a concave frame structure, so that the other part of the flexible screen 200 can be enclosed to limit and protect the flexible screen 200. Optionally, each side of the second frame portion 121 has at least one second cavity 1211 defined thereon, 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 of the first frame portion 111 is equal to the number of the second cavities 1211 of the second frame portion 121, and the first cavities 1111 and the second cavities 1211 are correspondingly disposed, so as to jointly accommodate the driving assembly 300.
Based on the above arrangement, when the first frame 110 and the second frame 120 are not separated, a portion of the flexible screen 200 is received inside the frame assembly 100, and another portion of the flexible screen 200 is displayed outside for the user to browse and operate. Optionally, the flexible screen 200 includes a first end and a second end, which are opposite to each other, the first end is movably disposed on the second frame 120, and the second end is fixed to the connecting 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 operate, 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 region 210, so that the area of the display region 210 can be increased; when the flexible screen 200 is folded, a portion of the display region 210 moves from the outside of the frame assembly 100 to the inside of the frame assembly 100 to become the hidden region 220, so that the area of the display region 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 flexible screen 200 may be provided with a support structure, such as a shaft member, in the middle, the flexible screen 200 is wound on the support structure, and the flexible screen 200 may be bent, curled, and the like by the support structure, 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 layer or the 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 present application, a rolling shaft 400 and a supporting rod 500 are additionally provided, the rolling shaft 400 is rotatably disposed in the housing portion 112, the middle region 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 housing portion 112, thereby playing a certain dredging role on the flexible screen 200, so as to reduce the moving resistance of the flexible screen 200, and improve the moving smoothness of the flexible screen 200. The supporting rod 500 is movably disposed on the second frame part 121, the first end of the flexible screen 200 is connected to the supporting rod 500, when the first frame 110 and the second frame 120 are relatively far away from each other, the second end of the flexible screen 200 moves along with the connecting part 122 in a direction far away from the first frame 110, and the first end of the flexible screen 200 pulls the supporting rod 500 to move in a direction close to 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 to each other, the supporting rod 500 moves on the second frame 120 in a direction away from the first frame 110, the first end of the flexible screen 200 is pulled through the supporting 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 thus the problems of wrinkles, curls and the like of the flexible screens 200 can be effectively prevented.
Further, in order to drive the supporting rod 500 to move relative to the second frame 120, the embodiment of the present application provides another driving assembly 300 between the supporting rod 500 and the connecting portion 122, and the driving assembly 300 can drive the supporting rod 500 to move relative to the second frame 120. Optionally, the driving assembly 300 has the same structure and operation principle as the driving assembly 300 for driving the first frame 110 and the second frame 120, and includes a flexible printed member 310 and an electro-deformable member 320 disposed on the flexible printed member 310, wherein one end of the flexible printed member 310 is connected to the supporting rod 500, and the other end is connected to the connecting portion 122. Thus, when the first frame 110 and the second frame 120 are relatively far away from each other, the driving assembly 300 disposed in the first cavity 1111 and the second cavity 1211 contracts to provide a traction force, the connecting portion 122 on the second frame 120 synchronously drives the second end of the flexible screen 200 to move in a direction far 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 in a direction close to the first frame 110 relative to the second frame 120, and meanwhile, 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 further, the hidden area 220 located inside the frame assembly 100 partially moves out and is converted into the display area 210, thereby increasing the display area of the flexible screen 200. When the first frame 110 and the second frame 120 are relatively close to each other, the driving assembly 300 disposed in the first cavity 1111 and the second cavity 1211 extends to provide a pushing force, the connecting portion 122 of the second frame 120 synchronously drives the second end of the flexible screen 200 to move toward the direction close to the first frame 110, and at this time, the driving assembly 300 connected between the supporting rod 500 and the fixing portion contracts and applies a traction force to the supporting rod 500, at the same time, the driving assembly 300 located in the first and second cavities 1111 and 1211 contracts, so as not to interfere with the folding process of the flexible screen 200, the first end of the flexible screen 200 moves along with the supporting rod 500 relative to the second frame 120 in a direction away from the first frame 110, so that the portion of the display region 210 located outside the frame assembly 100 moves inside the frame assembly 100 to be converted into the hidden region 220, reducing the display area of the flexible screen 200.
Based on the above arrangement, the two sets of driving assemblies 300 are used in cooperation with each other, so that the first frame 110 and the second frame 120 can be far away from each other 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 process of unfolding the flexible screen 200, the driving assembly 300 located in the first cavity 1111 and the second cavity 1211 extends, and the driving assembly 300 connected between the supporting rod 500 and the fixing portion extends; in the process of folding the flexible screen 200, the driving assembly 300 located in the first cavity 1111 and the second cavity 1211 contracts, and the driving assembly 300 connected between the supporting rod 500 and the fixing portion contracts.
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, the first direction is parallel to a direction in which the first frame 110 and the second frame 120 move relative to each other, and the supporting rod 500 is slidably connected to the sliding portion 1212. Optionally, the sliding portion 1212 may be a sliding groove, a sliding rail, or the like, and two ends of the supporting rod 500 are slidably connected to the sliding portions 1212 on the first frame portions 111 at two sides, respectively, so as to ensure that the unfolding or folding process of the flexible screen 200 is more stable and smooth.
In other embodiments, the electronic device may further include a winding shaft (not shown), which is rotatably disposed inside the housing portion 112. Alternatively, the take-up reel may include a driving motor as a power source for rotating the take-up reel, and the take-up reel is driven by the driving motor to rotate and is pulled by the take-up reel to take up 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 and curled. It should be noted here that the speed of the winding shaft for winding the flexible screen 200 is equal to the speed of the first frame 110 and the second frame 120 approaching relatively, so as to prevent the winding action of the flexible screen 200 and the approaching action of the two frames from interfering with each other.
In some embodiments, the electronic device has first and second sides that are oppositely disposed. Optionally, the first side and the second side are spaced apart along a thickness direction of the electronic device. The flexible screen 200 includes first and second ends that are oppositely disposed. It is understood that the first and second ends are disposed along the expanding or collapsing direction of the flexible screen 200. The second end of the flexible screen 200 is fixedly connected to the region of the second frame 120 located on the first side, and the first end of the flexible screen 200 is wound from the first side to the second side and extends toward the direction away from the first casing 110. It is understood that the first side is an upper side in a thickness direction of the electronic device, and the second side is a lower side in the thickness direction of the electronic device, whereby the flexible screen 200 is folded back from the upper side of the electronic device to the lower side of the electronic device after passing through the first frame 110.
Based on the above arrangement, when the first frame 110 and the second frame 120 are relatively folded, the first end of the flexible screen 200 is located at an end of the second frame 120 far from the first frame 110, and when the first frame 110 and the second frame 120 are relatively unfolded, the first end of the flexible screen 200 is located at an end of the second frame 120 near the first frame 110. It can be understood that, during the relative folding process of 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, so as to reduce the display area of the flexible screen 200. During the relative expansion of the first frame 110 and the second frame 120, as the flexible screen 200 moves, the flexible screen 200 on the lower side of the electronic device partially moves out of the frame assembly 100, 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; similarly, 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 element 310 may be a foldable FPC (flexible Printed circuit), which is a flexible Printed circuit board made of polyimide or polyester film as a base material, and has high reliability, excellent flexibility, high wiring density, light weight, thin thickness, good bending property, and the like. Based on this, when the electro-deformable member 320 is powered on, the foldable FPC may be driven to extend or contract to change the length of the flexible printed member, thereby driving the first frame 110 and the second frame 120 to be relatively far away or relatively close through the flexible printed member, or driving the support member to move relative to the second frame 120.
Further, referring to fig. 11, the flexible printed member 310 includes valley regions 311 and valley bottom regions 312 which are periodically and alternately arranged, and the electro-deformable member 320 is connected between the adjacent valley regions 311. The electro-deformable member 320 deforms when energized, thereby driving the two adjacent sets of valley-peak regions 311 away from or toward each other, and thereby changing the length of the flexible printed article 310. Optionally, a plurality of electrostrictive members 320 arranged side by side are connected between every two adjacent sets of valley-peak areas 311, so that the degree of expansion and contraction of the flexible printed member 310 in all positions in the direction perpendicular to the expansion and contraction direction can be ensured to be more uniform. In addition, the electro-deformable member 320 may be fixed to the valley and peak regions 311 by means of welding.
The electronic equipment in the embodiment of the application can be a mobile phone, a tablet computer, an electronic book reader, wearable equipment, vehicle-mounted equipment, unmanned aerial vehicle equipment and the like, and the embodiment of the application does not limit the specific type of the electronic equipment.
In summary, the electronic device disclosed in the embodiment of the present application does not adopt a motor for driving, so that the whole electronic device has a simple structure and a reduced volume, and when there is a display requirement for a full-screen such as playing games and watching videos, the flexible screen 200 can be unfolded to realize a large-area screen display, thereby improving the user experience of extreme games, audio and video; when the size of the electronic device is reduced due to carrying, the flexible screen 200 can be folded, so that the purposes of reducing the size and facilitating carrying are achieved.
While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
