Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner" and "outer" etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.
To switch the display screen of the display device in different sizes to improve the inconvenience of carrying the display device, please refer to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides a display device 100, where the display device 100 may include: the flexible screen 3, the first shell 1 and the second shell 2 which are connected with each other in a sliding way, and the supporting piece 4 which is movably connected between the first shell 1 and the second shell 2.
A first end 31 of the flexible screen 3 extends into the inner cavity 12 of the first housing 1 and a second end 32 of the flexible screen 3 is connected to the second housing 2. The flexible screen 3 is at least partially supported on the first supporting surface 11 of the first casing 1 and the second supporting surface 21 of the second casing 2. The first bearing surface 11 and the second bearing surface 21 are coplanar, so that the flatness of the flexible screen 3 on the first bearing surface 11 and the second bearing surface 21 can be ensured.
Further, the first casing 1 and the second casing 2 may slide relative to each other, for example, the first casing 1 and the second casing 2 may move toward each other (toward each other) or away from each other (away from each other), so that the flexible screen 3 can be expanded when the first casing 1 and the second casing 2 move away from each other or contracted when the first casing 1 and the second casing 2 move toward each other, thereby changing the display size. This allows the display size of the flexible screen 3 to be switched.
For example, when the flexible screen 3 is required to exhibit a large display size, it can be realized by a back-to-back movement (away from each other) between the first casing 1 and the second casing 2. For another example, when the flexible screen 3 is required to exhibit a small display size, it can be realized by the movement of the first casing 1 and the second casing 2 toward each other (approaching each other). This can realize the display size switching of the flexible screen 3, thereby improving the problem that the display apparatus 100 is not convenient to carry in a display state of a larger size of the flexible screen 3.
For the sake of the following description, the smaller size display state of the display apparatus 100 is defined as the first display state, and the larger size display state of the display apparatus 100 is defined as the second display state. Further, referring to fig. 3 and 4 in combination, the supporting member 4 is used to unfold when the first casing 1 and the second casing 2 move back to back, so as to support the area (for example, area a in fig. 4) of the flexible screen 3 at the gap 13 between the first casing 1 and the second casing 2. Can solve flexible screen 3 like this and show the problem that the fretwork does not have the support under the state at the second to avoid flexible screen 3 to be damaged, and then improve flexible screen 3's life.
In this embodiment, the display device 100 may be an intelligent electronic device such as a mobile phone and a tablet computer. In order to avoid the support member 4 occupying too much physical space of the display device 100 in the implementation process, the structure of the support member 4 needs to be designed to ensure that the support member 4 does not occupy too much physical space of the display device 100 when folded. To achieve this, referring to fig. 5 and 6, the supporting member 4 may include at least two supporting plates 42 (4 supporting plates 42 are taken as an example in fig. 5), and two adjacent supporting plates 42 are rotatably connected to each other by a rotating shaft 41.
Referring to fig. 1 and 5, a supporting plate 42 near one end of the first casing 1 is rotatably connected to the first casing 1 via a rotating shaft 41, and another supporting plate 42 near one end of the second casing 2 is rotatably connected to the second casing 2 via another rotating shaft 41. When the first casing 1 and the second casing 2 move towards each other, the adjacent support plates 42 rotate around the corresponding rotating shafts 41, so that the support plates 42 are folded and accommodated in the accommodating space formed by the first casing 1 and the second casing 2.
In this way, the size of the support member 4 can be reduced when the support member 4 is folded by the rotation of the support plate 42 around the rotating shaft 41, so that the support member 4 can be ensured not to occupy too much physical space of the display device 100 when folded, and the saved physical space can be used for installing other components, thereby improving the space utilization rate of the whole display device 100 and being beneficial to the thinning of the display device 100.
In practical applications, the inventor found that when the supporting plates 42 are folded away from each other, they may be folded toward the flexible screen 3, which may press the flexible screen 3, so that the flexible screen 3 may be raised when the display device 100 is switched from the second display state to the first display state. To improve this technical problem, the inventors have innovatively improved the structure around the support 4. As shown in fig. 7, one end of the first housing 1 is provided with a first stopper plate 17 extending in the direction of the second housing 2, and one end of the second housing 2 is provided with a second stopper plate 23 extending in the direction of the first housing 1.
Referring to fig. 7, the first limiting plate 17 is used for limiting the supporting plate 42 near one end of the first casing 1 when the supporting plates 42 are folded, and the second limiting plate 23 is used for limiting the supporting plate 42 near one end of the second casing 2 when the supporting plates 42 are folded. This enables the supporting plate 42 to be folded toward the side away from the flexible screen 3, thereby avoiding squeezing the flexible screen 3, and further avoiding the flexible screen 3 from being raised when the display device 100 is switched from the second display state to the first display state.
In order to achieve the cooperation of the first and second limiting plates 17 and 23 with the corresponding supporting plates 42, please refer to fig. 8, the inventor also innovatively modifies the supporting plates 42 close to the first casing 1 and the supporting plates 42 close to the second casing 2. The supporting plate 42 close to the first casing 1 is provided with a first groove 421 matched with the size of the first limiting plate 17, and the supporting plate 42 close to the second casing 2 is provided with a second groove 422 matched with the size of the second limiting plate 23.
When the support plates 42 are unfolded from each other, the first stopper plate 17 is fitted into the first recess 421 and the second stopper plate 23 is fitted into the second recess 422. This ensures flatness of the support plates 42 when they are unfolded from each other, thereby achieving support of the flexible screen 3.
When the supporting plates 42 are folded, the first limiting plate 17 and the second limiting plate 23 can abut against each other to be coplanar with the first bearing surface 11 and the second bearing surface 21. Like this, when display device 100 is in under the first display state, first bearing surface 11, second bearing surface 21, first limiting plate 17 and second limiting plate 23 can form complete bearing surface in order to support flexible screen 3, can improve display device 100 flexible screen 3 under the first display state and appear the problem that the fretwork does not have the support.
In specific implementation, in order to realize smooth switching between the first display state and the second display state of the display device 100, please continue to refer to fig. 1 and fig. 2, an opening 111 is formed at one end of the first housing 1 away from the second housing 2, a rolling element 6 is disposed at the opening 111, and a movable connecting plate 14 is disposed in the inner cavity 12 of the first housing 1. The flexible screen 3 is wound around the rolling member 6, extends into the inner cavity 12 of the first housing 1 through the opening 111, and is fixedly connected to the movable connecting plate 14.
It will be appreciated that as the first and second housings 1, 2 are moved away from each other, the flexible screen 3 stretches and moves the articulating plate 14 within the internal cavity 12 in the direction of the rolling elements 6. When the first housing 1 and the second housing 2 are moved towards each other, the flexible screen 3 is driven by the flexible connecting plate 14 along the rolling elements 6 to partially extend into the inner cavity 12. In this manner, by providing the roller 6, smooth switching of the display size of the flexible screen 3 can be achieved, thereby achieving smooth switching of the display apparatus 100 between the first display state and the second display state.
In practical applications, in order to improve the connection stability between the flexible screen 3 and the movable connection plate 14, please refer to fig. 4, the movable connection plate 14 may include a fixed plate 141 and a movable plate 142. The movable plate 142 is disposed between the inner bottom wall 151 of the first housing 1 and the inner top wall 152 of the first housing 1, and one end of the fixed plate 141 is fixedly connected to the movable plate 142 and the other end extends toward the rolling member 6. The fixing plate 141 may be parallel to the first bearing surface 11.
Further, the fixing plate 141, the movable plate 142 and the inner top wall 152 together form a receiving groove therebetween. The first end 31 of the flexible screen 3 extends into the accommodating groove and is fixedly connected to the fixed plate 141 and the movable plate 142, and the fixed plate 141 is used for bearing the portion of the flexible screen 3 located in the accommodating groove. As described above, by fixing the first end 31 of the flexible panel 3 to the fixed plate 141 and the movable plate 142, the connection stability between the flexible panel 3 and the movable connection plate 14 can be improved.
In practical applications, in order to ensure that the first housing 1 and the second housing 2 do not deviate from each other when sliding, please refer to fig. 4, a first sliding portion 16 is disposed at an end of the first housing 1 close to the second housing 2, and a second sliding portion 22 is disposed at an end of the second housing 2 close to the first housing 1. The second sliding portion 22 is sleeved on the first sliding portion 16 to realize the sliding connection between the first casing 1 and the second casing 2. In the present embodiment, the cross-sectional shapes of the first sliding portion 16 and the second sliding portion 22 may be rectangular, which can ensure that the first casing 1 and the second casing 2 do not deviate in position when sliding each other.
In practical implementation, the inventor finds that when the first housing 1 and the second housing 2 move towards each other to achieve the contraction of the flexible screen 3, if the flexible screen 3 encounters a resistance force (for example, the rolling members 6 are jammed) when extending into the first housing 1, the flexible screen 3 is warped upwards as shown in fig. 9 during the contraction process, so that it is difficult to achieve effective contraction of the flexible screen 3, which may affect the display effect of the flexible screen 3 and the normal use of the display device 100.
To improve the technical problem of the flexible screen 3 warping upwards during the shrinking process, please refer to fig. 4, the display device 100 may further include an elastic member 5. The elastic member 5 is disposed in the inner cavity 12 and connected between the movable plate 142 and an end of the first housing 1 close to the second housing 2. When the display device 100 is in the first display state, the elastic member 5 is in a slightly stretched state. In this way, the elastic member 5 may slightly pull the flexible screen 3 through the movable plate 142, so that the flexible screen 3 maintains tension when the display device 100 is in the first display state, to ensure flatness of the flexible screen 3.
Referring to fig. 4, when the first housing 1 and the second housing 2 move back to back, the flexible screen 3 drives the movable plate 142 to move near the rolling element 6 in the inner cavity 12, and the movable plate 142 applies a pulling force to the elastic element 5 to further stretch the elastic element 5 to accumulate elastic potential energy. When the first housing 1 and the second housing 2 move towards each other, the elastic member 5 releases the elastic potential energy and drives the flexible screen 3 to move towards the first sliding portion 16 in the inner cavity 12 through the movable plate 142. In this way, the flexible screen 3 can be pulled into the inner cavity of the first housing 1 by the elastic member 5, thereby preventing the flexible screen 3 from being warped upwards during the contraction process. It can be understood that by providing the elastic member 5, it can be ensured that the flexible screen 3 continuously maintains the tension during the stretching process, thereby preventing the flexible screen 3 from being wrinkled during the stretching process.
In practical applications, in order to lock the display device 100 in the second display state, please refer to fig. 4 and 10 in combination, the display device 100 may further include a locking member 7, one end of the locking member 7 is connected to the first sliding portion 16, and the other end of the locking member 7 extends into the second housing 2. The locking member 7 is used to lock the first casing 1 and the second casing 2 when the first casing 1 and the second casing 2 move back to back, thereby achieving locking of the display apparatus 100 in the second display state. Further, when the locking pieces 7 release the locking of the first and second housings 1 and 2, the first and second housings 1 and 2 are moved toward each other to effect the contraction of the flexible screen 3.
In this embodiment, the locking member 7 may be a lock lever. As shown in fig. 10, the locking member 7 may be ejected from the second housing 2 (e.g., at an angle in the Y direction of fig. 11) when the first housing 1 and the second housing 2 move back to back, and then may abut against the second housing 2. Therefore, the elastic member 5 cannot drive the flexible screen 3 to contract, so that the first housing 1 and the second housing 2 cannot be indirectly driven to move towards each other, and the first housing 1 and the second housing 2 can be locked.
Further, the locking of the first housing 1 and the second housing 2 can also be released by acting on the locking member 7. For example, the locking of the first housing 1 and the second housing 2 may be released by pressing the locking member 7, and when the first housing 1 and the second housing 2 are moved toward each other to contract the flexible screen 3, the locking member 7 may be inserted into a space provided in the second housing 2 in advance to accommodate the locking member 7.
In the present embodiment, since the flexible screen 3 is only supported on the first supporting surface 11 but not fixed thereon, in order to ensure that the flexible screen 3 does not wrinkle during use, in an alternative embodiment, the region of the flexible screen 3 on the second supporting surface 21 is fixed on the second supporting surface 21. Like this, can make the fixed area of laminating maximize between flexible screen 3 and the second bearing surface 21 to guarantee the stability of flexible screen 3 on first bearing surface 11 and second bearing surface 21, avoid flexible screen 3 fold to appear in the use.
In an implementation process, in order to realize accurate switching of the display screen of the flexible screen 3, please refer to fig. 2 and 11, the display device 100 may further include a position sensor 8 disposed at the opening 111 and near the rolling member 6, and a processor 9 disposed in the first housing 1 or the second housing 2. A position sensor 8 is arranged at the opening 111 and in close proximity to the roller 6 for position detection of the flexible screen 3 and for sending the detected position data to said processor 9. The processor 9 may adjust the display parameters of the display device 100 based on the position data.
In the present embodiment, the position data may be used to characterize the size of the flexible screen 3, for example, the position data1 may be used to characterize the size of the flexible screen 3 as a small display size, and the position data2 may be used to characterize the size of the flexible screen 3 as a large display size. Further, the processor 9 may adjust parameters such as a resolution, a refresh rate, and a display brightness value of the flexible screen 3 according to different position data, so as to implement accurate switching of the display screen of the flexible screen 3.
On the basis of the above, the embodiment of the present invention explains the switching process of the display apparatus 100 in the display state of different sizes.
First, please refer to fig. 1, which is a schematic structural diagram of the display apparatus 100 in a first display state. When it is desired to switch the display device 100 from the first display state to the second display state, the first housing 1 and/or the second housing 2 may be acted on such that the first housing 1 and the second housing 2 move away from each other. For example, taking the example that the second housing 2 is relatively stationary as an example, when the first housing 1 and the second housing 2 move back to back, the first housing 1 may move away from the second housing 2 along the direction X shown in fig. 1, so as to cause the flexible screen 3 to extend and unfold around the rolling element 6.
Next, referring to fig. 1 and fig. 3, when the first housing 1 is far away from the second housing 2 along the X direction, the supporting element 4 is unfolded between the first housing 1 and the second housing 2. The flexible screen 3 extends from the first housing 1 around the rolling members 6 in the-X direction and is carried on the first carrying surface 11 to achieve an increase in the adjustment of the display size of the flexible screen 3. In addition, the flexible screen 3 also drives the articulation plate 14 towards the rolling member 6 to stretch the elastic member 5. At the same time, the locking member 7 gradually protrudes from the second housing 2.
Finally, referring to fig. 1, fig. 3 and fig. 4, when the supporting member 4 is fully unfolded, the locking member 7 extends from the second housing 2 and is held between the first housing 1 and the second housing 2. The support 4, which is fully unfolded at this time, can support the area of the flexible screen 3 located at the gap 13 between the first casing 1 and the second casing 2, thereby completing the switching of the display apparatus 100 from the first display state to the second display state.
Alternatively, if it is required to switch the display device 100 from the second display state to the first display state, the locking member 7 may be acted to unlock the first housing 1 and the second housing 2, and then the first housing 1 and/or the second housing 2 may be acted to move the first housing 1 and the second housing 2 toward each other and approach each other, the elastic member 5 releases the elastic potential energy and drives the flexible screen 3 to retract into the first housing 1 through the movable connecting plate 14, and the supporting member 4 is switched from the unfolded state to the folded state and is accommodated in the accommodating space formed by the first housing 1 and the second housing 2. This may enable switching of the display device 100 from the second display state to the first display state.
In summary, the display device 100 provided in the embodiment of the present invention can implement switching of the size of the flexible screen 3, so as to meet the requirement of a user on different sizes of display screens and improve the problem that the display device 100 is not convenient to carry when the flexible screen 3 is in the second display state. Through set up support piece 3 between first casing 1 and second casing 2, can solve flexible screen 3 and do not have the problem of support at the fretwork under the second display state. By providing the elastic member 5 in the first housing 1, the flexible screen 3 can be continuously kept under tension in different size display states of the display apparatus 100 and in a switching process of the display apparatus 100 between the different size display states, so that the smoothness of the flexible screen 3 is ensured, and wrinkles of the flexible screen 3 are avoided.
