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 14, an embodiment of the present application discloses an electronic device including a flexible screen 200, a housing 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. Alternatively, the flexible screen 200 may adjust the area of the display region by being unfolded or folded. When a user needs a large screen, the flexible screen 200 is unfolded, so that the user can be provided with a large-screen display experience, and the user can browse and operate conveniently. When the user needs a small screen, the flexible screen 200 is folded, so that the user can conveniently carry the small screen.
The housing assembly 100 is a basic mounting component of the electronic device, the flexible screen 200 can be mounted on the housing assembly 100, and the flexible screen 200 can be supported and protected by the housing assembly 100. The frame assembly 100 includes a first housing 110 and a second housing 120, and the first housing 110 is slidably engaged with the second housing 120. The first housing 110 and the second housing 120 slide relative to each other, so as to drive the flexible screen 200 to expand or contract, thereby adjusting the display area of the flexible screen 200. Alternatively, the first housing 110 may be a concave housing, the second housing 120 may be a concave housing, a receiving space is formed between the first housing 110 and the second housing 120 after the first housing 110 and the second housing 120 are assembled with each other, and the flexible screen 200 is at least partially disposed between the first housing 110 and the second housing 120.
In consideration of the factors that the flexible screen 200 needs to be unfolded or folded, the flexible screen 200 is disposed in the housing assembly 100, and one end of the flexible screen 200 is connected to the second housing 120 and the other end is movable relative to the first housing 110. In the relative sliding process of the first housing 110 and the second housing 120, the flexible screen 200 is driven to move, so that the flexible screen 200 is unfolded or folded. Optionally, the other end of the flexible screen 200 may be slidably connected to the first housing 110, or may be rolled on a rolling device disposed on the first housing 110, and as the second housing 120 slides relative to the first housing 110, the other end of the flexible screen 200 may be adaptively adjusted, so as to neither interfere with the extension and retraction of the housing assembly 100, but also achieve the adjustment of the display area of the flexible screen itself.
When a large screen is required, the first shell 110 and the second shell 120 are relatively far away, and at this time, the second shell 120 synchronously pulls one end of the flexible screen 200 away from the first shell 110, so that the flexible screen 200 is unfolded, and a large screen experience is provided for a user. When a small screen is required, the first casing 110 and the second casing 120 are relatively close to each other, and at this time, one ends of the second casing 120 and the flexible screen 200 are both close to the first casing 110, so that the flexible screen 200 is folded, and a small screen experience is provided for a user.
Here, in order to enable the flexible screen 200 to be folded smoothly, a power device may be further provided. For example, a drawing device is provided at one end of the flexible screen 200 located at the first housing 110, and the other end of the flexible screen 200 is drawn by the drawing device when the first housing 110 and the second housing 120 are relatively close to each other, so that a portion of the flexible screen 200 enters the inside of the housing assembly 100, thereby reducing the area of the flexible screen 200 located outside the housing assembly 100 to reduce the display area. The traction device can pull the other end of the flexible screen 200 in a linear traction manner, and can also pull the other end of the flexible screen 200 in a winding manner. The specific traction mode of the traction device is not limited in the embodiment of the application.
Referring to fig. 4 and 6, in the embodiment of the present application, the driving assembly 300 includes a magnetic member 310 and a first coil 320, and the first coil 320 interacts with the magnetic member 310 to provide a driving force for the relative movement of the first housing 110 and the second housing 120. To mount the driving assembly 300, a cavity 113 is disposed on the first housing 110, the magnetic member 310 is disposed in the cavity 113 and is movable in the cavity 113, and the first coil 320 is disposed on the first housing 110 and adjacent to the cavity 113, so that the first coil 320 interacts with the magnetic member 310 in the cavity 113. Further, in order to connect the magnetic member 310 to the second housing 120, in the embodiment of the present application, a connector 410 is disposed between the magnetic member 310 and the second housing 120, and the magnetic member 310 and the second housing 120 are connected together by the connector 410. The connecting member 410 is also located within the cavity 113 and is movable within the cavity 113. Thus, when the first coil 320 interacts with the magnetic element 310, the magnetic element 310 may move the second housing 120 through the connecting element 410, so as to move the second housing 120 closer to or farther away from the first housing 110.
For example, when the first coil 320 is energized in the first manner, the first coil 320 and the magnetic member 310 form a repulsive force, and the magnetic member 310, the connecting member 410 and the second housing 120 are all moved away from the first housing 110 by the repulsive force, so that the second housing 120 is separated from the first housing 110. In the process, the second housing 120 pulls one end of the flexible screen 200 and moves the other end of the flexible screen 200 relative to the first housing 110, thereby unfolding the flexible screen 200 to provide a large screen experience for the user. When the first coil 320 is energized in the second form, the first coil 320 and the magnetic member 310 form an attractive force, and the magnetic member 310, the connecting member 410 and the second housing 120 all move toward the first housing 110 under the driving action of the attractive force, so that the second housing 120 and the first housing 110 contract relatively. In this process, the flexible screen 200 is also folded to provide a small screen experience for the user. It should be noted that the principle of the interaction between the first coil 320 and the magnetic member 310 can be referred to the related art, and will not be described in detail herein.
Based on the above arrangement, under the condition that the magnetic element 310 interacts with the first coil 320, the magnetic element 310 can move in the cavity 113, the magnetic element 310 synchronously drives the connecting element 410, and drives the second housing 120 to move relative to the first housing 110 through the connecting element 410, so that the second housing 120 and the first housing 110 are relatively close to or relatively far away from each other, thereby realizing expansion or contraction. Meanwhile, with the relative movement of the first housing 110 and the second housing 120, the flexible screen 200 may be unfolded or folded with the relative movement of the first housing 110 and the second housing 120, thereby changing the display area of the flexible screen 200. Compare in conventional motor drive mode, drive assembly 300 in this application is succinct more, small and exquisite, has reduced the occupied space of drive assembly 300, has alleviated the influence to the overall arrangement of other electronic components in electronic equipment.
With continued reference to fig. 4 and 6, in order to realize the relative movement between the flexible screen 200 and the first housing 110, in the embodiment of the present application, a supporting member 420 is additionally provided, the supporting member 420 is movably disposed on the first housing 110, and the other end of the flexible screen 200 is fixedly connected to the supporting member 420. Alternatively, the support member 420 may be a bar structure extending in the width direction of the flexible screen 200 and fixed to the other end of the flexible screen 200 in the length direction. Thus, the other end of the flexible screen 200 is slidably connected to the first housing 110 through the supporting member 420, so that the flexible screen 200 can be unfolded or folded. Alternatively, the other end of the flexible screen 200 passes through an upper portion in the thickness direction of the first housing 110 and is wound to a lower portion in the thickness direction of the first housing 110. During the process of unfolding or folding the flexible screen 200, the upper region of the flexible screen 200 moves in the same direction as the second housing 120, and the lower region of the flexible screen 200 moves in the opposite direction to the second housing 120. Based on the above, a portion of the flexible screen 200 may be stocked in the first housing 110, thereby providing a larger display area through the flexible screen 200. Of course, in other embodiments, the other end of the flexible screen 200 may pass through the upper portion of the first housing 110 in the thickness direction and be wound to the lower portion of the first housing 110 in the thickness direction, and the other end of the flexible screen 200 may be wound on the winding device. During the unfolding process of the flexible screen 200, the winding device releases part of the flexible screen 200, and during the folding process of the flexible screen 200, the winding device winds part of the flexible screen 200, so that the requirements of unfolding or folding the flexible screen 200 can be met.
In order to make the sliding between the supporting member 420 and the first casing 110 more stable, in the embodiment of the present application, the sliding slot 114 is disposed on the first casing 110, the sliding slot 114 extends along the direction of the relative movement between the first casing 110 and the second casing 120, and the supporting member 420 is slidably disposed in the sliding slot 114. Optionally, the length of the sliding slot 114 is not less than the maximum distance of the relative movement between the first casing 110 and the second casing 120, so as to ensure that the first casing 110 and the second casing 120 are not prevented by the support 420 during the relative moving away process. Based on the above arrangement, the flexible screen 200 can be more stably and smoothly unfolded or folded through the sliding connection between the supporting member 420 and the sliding groove 114.
Referring to fig. 11 and 12, in order to make the flexible screen 200 less prone to wrinkle during the folding process, and to achieve perfect folding of the flexible screen 200, a driving device is added at the other end of the flexible screen 200 in the embodiment of the present application. Specifically, the second coil 330 is disposed at a region of the first housing 110 adjacent to the support 420, and accordingly, the support 420 is disposed as a magnetic support. With the second coil 330 energized, the second coil 330 interacts with the magnetic support to drive the magnetic support to move. Alternatively, a sliding structure is provided on the first housing 110, and the magnetic support is provided on the first housing 110 through the sliding structure. In a more specific embodiment, the magnetic support is disposed in the sliding slot 114 of the first housing 110, such that the magnetic support is movable relative to the first housing 110. Accordingly, the second coil 330 is disposed in the vicinity of the chute 114. When the second coil 330 is energized, it interacts with the magnetic support to drive the magnetic support to slide in the sliding slot 114, so as to facilitate the folding of the flexible screen 200.
It should be noted here that, during the unfolding process of the flexible screen 200, the interaction between the first coil 320 and the magnetic member 310 may generate a pulling force on one end of the flexible screen 200, and at this time, to ensure that the flexible screen 200 is flat and not wrinkled, the second coil 330 may not be powered on, so that the unfolding of the flexible screen 200 provides a driving force by virtue of the interaction between the first coil 320 and the magnetic member 310. In the process of folding the flexible screen 200, the interaction between the first coil 320 and the magnetic member 310 generates a pushing force on one end of the flexible screen 200, and at this time, in order to ensure that the flexible screen 200 is flat and not folded, the second coil 330 is powered on and generates a pulling force on the other end of the flexible screen 200, so that the folding of the flexible screen 200 depends on the interaction between the first coil 320 and the magnetic member 310, and the interaction between the second coil 330 and the magnetic support member. In addition, in the folding process of the flexible screen 200, the first coil 320 may be powered off to power on the second coil 330, and at this time, the second coil 330 interacts with the magnetic support to generate a pulling force on the other end of the flexible screen 200, so that the folding of the flexible screen 200 provides a driving force by the interaction of the second coil 330 and the magnetic support.
Referring to fig. 7 and 9, in some embodiments, the driving assembly 300 includes a plurality of rows of first coils 320, the plurality of rows of first coils 320 are spaced apart in a direction in which the first housing 110 and the second housing 120 move relative to each other, and the plurality of rows of first coils 320 may interact with the magnetic members 310, respectively. For example, the first coils 320 of the multiple rows are all energized in the same manner, and the driving forces generated by the interaction between the first coils 320 of the multiple rows and the magnetic member 310 are the same in magnitude and direction, so that the magnetic member 310 can be ensured to move in the same direction.
It should be noted that, under some special conditions, the moving path of the magnetic member 310 may be affected. For example, when the magnetic member 310 is initially located in the left region of the rows of the first coils 320, the number of the first coils 320 on the left side of the magnetic member 310 is less than the number of the first coils 320 on the right side, and at this time, if each row of the first coils 320 generates a force with the magnetic member 310, the driving force generated by the interaction between the left first coils 320 and the magnetic member 310 is less than the driving force generated by the interaction between the right first coils 320 and the magnetic member 310, so that the right first coils 320 dominate the effect of the magnetic member 310; and switches the direction of the driving force when reaching the middle position of the rows of the first coils 320, which is not favorable for the magnetic member 310 to move along the desired path. In contrast, when the magnetic member 310 is initially located at the right region of the rows of the first coils 320, the left-side first coil 320 dominates the action of the magnetic member 310 and switches the direction of the driving force when reaching the middle position of the rows of the first coils 320, which is not favorable for the magnetic member 310 to move along the desired path. When the magnetic members 310 are initially positioned at the middle of the rows of the first coils 320, the magnetic members 310 are equally acted on by the left and right sides, so that the magnetic members 310 do not move.
Based on the above working conditions, in the embodiment of the present application, the initial position and the power-on mode of the magnetic member 310 are optimally designed to avoid that the magnetic member 310 cannot move along the expected path. The method comprises the following specific steps:
when the first casing 110 and the second casing 120 are relatively folded, the magnetic member 310 is located at a first position in the cavity 113, and when the first casing 110 and the second casing 120 are relatively extended, the magnetic member 310 is located at a second position in the cavity 113. When the magnetic member 310 and each row of the first coils 320 repel each other, the first position is located between the first row and the second row, and the second position is located between the penultimate row and the penultimate row; when the magnetic member 310 and each row of the first coils 320 are attracted to each other, the first position is located on a side of the first row facing away from the second row, and the second position is located on a side of the penultimate row facing away from the penultimate row.
Referring to fig. 14, in the embodiment of the present application, the first coils 320 are disposed on the first casing 110 along the extending direction of the cavity 113, and the first coils 320 may be sequentially defined as row 1, row 2, row 3 …, row N +1, and the like in a direction that the first casing 110 faces the second casing 120, where N is a constant.
Further, the first coils 320 in the plurality of rows are sequentially energized along a first direction, and the first direction is parallel to the relative movement direction of the first casing 110 and the second casing 120.
Based on the above arrangement, the specific operation principle of the driving assembly 300 in the embodiment of the present application is as follows:
in the first case, the first coil 320 and the magnetic member 310 repel each other.
In an initial state, the magnetic member 310 is located between the 1 st row and the 2 nd row, the 1 st row first coil 320 is energized, so that the 1 st row first coil 320 and the magnetic member 310 generate a repulsive force, and at this time, the 1 st row first coil 320 pushes the magnetic member 310 located between the 1 st row and the 2 nd row to move towards the second housing 120, so that the magnetic member 310 moves between the 2 nd row and the 3 rd row; then the first coil 320 in the 1 st row is powered off, the first coil 320 in the 2 nd row is powered on, so that the first coil 320 in the 2 nd row and the magnetic member 310 generate a repulsive force, and at this time, the first coil 320 in the 2 nd row pushes the magnetic member 310 between the 2 nd row and the 3 rd row to move continuously towards the second housing 120, so that the magnetic member 310 moves to between the 3 rd row and the 4 th row; by analogy, the magnetic member 310 is finally moved to a position between the nth row and the (N + 1) th row to stop, so that the second shell 120 is extended relative to the first shell 110 by sequential action of the first coils 320 in multiple rows and the magnetic member 310, and the flexible screen 200 is driven to be unfolded by the first shell 110 and the second shell 120.
On the contrary, in the initial state, the magnetic member 310 is located between the N +1 th row and the N-1 th row, the N +1 th row first coil 320 is energized, so that the N +1 th row first coil 320 and the magnetic member 310 generate a repulsive force, and at this time, the N +1 th row first coil 320 pushes the magnetic member 310 to move towards the first housing 110, so that the magnetic member 310 moves to a position between the N-1 th row and the N +1 th row; then the first coil 320 in the N +1 th row is powered off, the first coil 320 in the nth row is powered on, so that the first coil 320 in the nth row and the magnetic member 310 generate a repulsive force, and at this time, the first coil 320 in the nth row pushes the magnetic member 310 between the nth row and the nth-1 th row to continue moving towards the first housing 110, so that the magnetic member 310 moves to the front of the nth-1 th row and the nth-2 nd row; by analogy, the magnetic member 310 is finally moved to the position between the 2 nd row and the 1 st row and stopped, so that the second casing 120 is folded relative to the first casing 110 by the sequential action of the rows of the first coils 320 and the magnetic member 310, and the flexible screen 200 is folded by the first casing 110 and the second casing 120.
In the second case, the first coil 320 and the magnetic member 310 are attracted to each other.
This case is substantially similar to the first case in the specific principle, and the main difference is that the first coil 320 is energized in the opposite direction to the first case, so that the rows of the first coils 320 are sequentially attracted to the magnetic member 310 to drive the magnetic member 310 to move. In addition, the initial position of the magnetic member 310 is changed due to the opposite direction of the force of the first coil 320 and the magnetic member 310. In some embodiments, in the initial state, the magnetic member 310 is disposed before the row 1, then the first coils 320 are sequentially energized, the magnetic member 310 is sequentially attracted by the first coils 320, and the movement is stopped when the magnetic member 310 reaches the row N +1, so that the second housing 120 is extended relative to the first housing 110, and the flexible screen 200 is unfolded by the first housing 110 and the second housing 120. On the contrary, in the initial state, the magnetic member 310 is disposed behind the (N + 1) th row, and then the first coils 320 in multiple rows are sequentially energized, the magnetic member 310 is sequentially attracted by the first coils 320 in multiple rows, and when the magnetic member 310 reaches the position before the 1 st row, the movement is stopped, so that the second housing 120 is retracted relative to the first housing 110, and the flexible screen 200 is folded by the first housing 110 and the second housing 120.
In the embodiment of the application, the power on of the coils in multiple rows is controlled through an algorithm so as to meet the actual requirement.
With continued reference to fig. 7 and 9, in order to make the moving process of the magnetic member 310 more smooth, in the embodiment of the present application, each row of the first coils 320 includes a plurality of first coils 320, and the plurality of first coils 320 are connected in series through the flexible circuit board 510. Optionally, the plurality of first coils 320 in each row may be uniformly and alternately arranged along the length direction of the magnetic member 310, so as to ensure that the stress on each section of the magnetic member 310 is more uniform, improve the moving stability of the magnetic member 310, and prevent the magnetic member 310 from being stressed unevenly to cause the inclination problem.
Further, the electronic device further includes a connector 520, and the flexible circuit board 510 is electrically connected to a main system of the electronic device through the connector 520, so that the power-on condition of the rows of the first coils 320 can be controlled by the main system of the electronic device.
Referring to fig. 4 and 6, in some embodiments, an electronic device has first and second sides disposed opposite one another. 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 first end of the flexible screen 200 is fixedly connected to the area of the second housing 120 located at the first side, and the second end of the flexible screen 200 is wound from the first side to the second side and extends toward the second housing 120. 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, 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 case 110.
Based on the above arrangement, when the first casing 110 and the second casing 120 are relatively folded, the second end of the flexible screen 200 is located at an end of the sliding slot 114 adjacent to the second casing 120, and when the first casing 110 and the second casing 120 are relatively extended, the second end is located at an end of the sliding slot 114 far away from the second casing 120. It can be understood that, during the relative folding process of the first casing 110 and the second casing 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 casing assembly 100, so as to reduce the display area of the flexible screen 200. During the relative extension of the first housing 110 and the second housing 120, as the flexible screen 200 moves, the flexible screen 200 on the lower side of the electronic device partially moves out of the housing assembly 100, thereby increasing the display area of the flexible screen 200. In addition, the second end is located at an end of the sliding chute 114 adjacent to the second housing 120, and is not limited to the end of the sliding chute 114, but also includes a region near the end; similarly, the second end is located at an end of the sliding chute 114 far from the second housing 120, and is not limited to the end of the sliding chute 114, but also includes a region near the end.
With continued reference to fig. 4 and 6, in order to facilitate the folding of the flexible screen 200, a roller 600 may be further disposed on the first casing 110, the roller 600 may be rotatably connected to the first casing 110, and a second end of the flexible screen 200 may be wound from the first side to the second side through the roller 600 and extend toward the second casing 120. Specifically, the second end of the flexible screen 200 extends from the upper side of the first casing 110 in the thickness direction to the lower side of the first casing 110 in the thickness direction, bypassing the roller 600, and is fixedly connected to the support member 420. Thus, in the process of unfolding or folding the flexible screen 200, the flexible screen 200 moves on the roller 600, and due to the existence of friction, the roller 600 rotates relative to the first casing 110, so that the direct sliding mode of the flexible screen 200 and the first casing 110 is converted into the rolling mode of the flexible screen 200 between the roller 600 and the first casing 110, and further friction resistance is reduced, the flexible screen 200 is conveniently unfolded or folded, and the energy consumption of the driving assembly 300 is reduced to a certain extent.
Referring to fig. 3 and 5, in order to ensure the motion precision of the expansion or contraction between the first housing 110 and the second housing 120, the embodiment of the present application provides a first guide 700 on the first housing 110, and correspondingly, a second guide 720 on the second housing 120, wherein one of the first guide 700 and the second guide 720 has a guide channel 711, and the other is movably disposed in the guide channel 711. Based on this, when the first housing 110 and the second housing 120 relatively extend or contract, the first guide 700 and the second guide 720 are in guiding engagement, thereby ensuring the movement accuracy.
In some embodiments, the first guide 700 may be a first guide bar, and the second guide 720 may be a second guide bar, the first guide bar being welded to the first housing 110 and extending toward the second housing 120, and one end of the second guide bar being welded to the second housing 120 and extending toward the first housing 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 711, and the second guide bar partially penetrates the guide channel 711 and is movable in the guide channel 711. Of course, the second guide bar may be provided with a hole along the length direction thereof to form the guide channel 711, and the first guide bar may be slidably connected to the guide channel 711. 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 housing 110 and the second housing 120 is achieved. Besides, a guide rail may be disposed on the first housing 110 or the second housing 120, so that the two housings are slidably connected through the guide rail, and the first housing 110 and the second housing 120 may be relatively far away from each other or relatively close to each other. The sliding fit between the first housing 110 and the second housing 120 is not limited in the embodiment of the present application.
With continued reference to fig. 3 and 5, in some embodiments, the first housing 110 includes two first bracket portions 111 disposed opposite to each other and a shell portion 112 connecting the two first bracket portions 111, and accordingly, the second housing 120 includes two second bracket portions 121 disposed opposite to each other and a fixing portion 122 connecting the two second bracket portions 121, and the first bracket portions 111 and the second bracket portions 121 are disposed correspondingly. Alternatively, the first housing 110 may be a concave housing structure. Accordingly, a part of the flexible panel 200 can be enclosed by the two first frame parts 111 and the housing part 112, and the flexible panel 200 can be restricted. The second housing 120 may also be a concave housing structure. Therefore, the other part of the flexible screen 200 can be enclosed by the two second bracket parts 121 and the fixing part 122, so that the flexible screen 200 can be limited.
Referring to fig. 13, in order to ensure that the flexible screen 200 remains flat and non-wrinkled, the flexible screen 200 in the embodiment of the present application includes a flexible display layer 210, an organic glue layer 220, and a semi-rigid layer 230, and the flexible display layer 210, the organic glue layer 220, and the semi-rigid layer 230 are sequentially stacked from the outside to the inside of the housing assembly 100. Based on the above multilayer arrangement, the overall rigidity of the flexible screen 200 is improved, so that the flexible screen 200 is basically free from the phenomenon of uneven folds in the process of unfolding or folding along with the relative movement of the first shell 110 and the second shell 120, and the user experience is improved.
Based on the flexible screen 200 with multiple layers, when the first casing 110 and the second casing 120 are folded, a traction device does not need to be arranged at one end of the flexible screen 200, which is slidably connected with the first casing 110, in this case, when the second casing 120 is close to the first casing 110, the flexible screen 200 can also move relative to the first casing 110 along with the second casing 120 through the characteristics of the flexible screen 200, so that the flexible screen 200 is ensured not to be wrinkled in the folding process.
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.
