Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

In the description of the present invention, it should be understood that the terms "center", "lateral", "top", "bottom", "left", "right", "vertical", "horizontal", "top", " The orientation or positional relationship indicated by "bottom", "inner" and "outer" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the indicated device or position. Elements must have a particular orientation, be constructed and operate in a particular orientation and are therefore not to be construed as limitations of the invention. Also, it will be noted that 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 considered to be "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.

In order to realize the switching of the display screen of the display device under different sizes, so as to improve the problem that the display device is inconvenient to carry, please refer to FIG. 1 and FIG. 2 in combination. It includes: a flexible screen 3 , a first casing 1 and a second casing 2 that are slidably connected to each other, and a support 4 that is movably connected between the first casing 1 and the second casing 2 .

The first end 31 of the flexible screen 3 extends into the inner cavity 12 of the first casing 1 , and the second end 32 of the flexible screen 3 is connected to the second casing 2 . The flexible screen 3 is at least partially supported on the first bearing surface 11 of the first casing 1 and the second bearing surface 21 of the second casing 2 . The first bearing surface 11 and the second bearing surface 21 are on the same plane, 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 shell 1 and the second shell 2 can slide relative to each other, for example, the first shell 1 and the second shell 2 can move toward each other (close to each other), or they can move back (away from each other), In this way, the flexible screen 3 can be expanded when the first casing 1 and the second casing 2 are far away from each other, or can be contracted when the first casing 1 and the second casing 2 are close to each other, thereby changing the display size. In this way, the display size of the flexible screen 3 can be switched.

For example, when the flexible screen 3 is required to present a larger display size, it can be achieved by the backward movement (away from each other) between the first casing 1 and the second casing 2 . For another example, when the flexible screen 3 needs to present a smaller display size, it can be achieved by the relative movement (closer to each other) between the first casing 1 and the second casing 2 . In this way, the display size switching of the flexible screen 3 can be realized, thereby improving the problem that the display device 100 is inconvenient to carry when the flexible screen 3 is in a display state of a larger size.

For the convenience of subsequent description, the smaller size display state of the display device 100 is defined as the first display state, and the larger size display state of the display device 100 is defined as the second display state. Further, please refer to FIG. 3 and FIG. 4 in combination, the support member 4 is used to expand when the first housing 1 and the second housing 2 move back, so that the flexible screen 3 is located in the first housing 1 and the second housing 1 and the second housing. The area at the gap 13 between the bodies 2 (eg area A in FIG. 4 ) is supported. This can solve the problem that the flexible screen 3 is hollow and unsupported in the second display state, thereby preventing the flexible screen 3 from being damaged, thereby improving the service life of the flexible screen 3 .

In this embodiment, the display device 100 may be an intelligent electronic device such as a mobile phone and a tablet computer. In the specific implementation process, in order to prevent the support member 4 from occupying too much physical space of the display device 100 , 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. For this purpose, please refer to FIG. 5 and FIG. 6 in combination, the support member 4 may include at least two support plates 42 (4 support plates 42 are taken as an example in FIG. 5 ), and two adjacent support plates 42 are located between each other. Rotationally connected through the shaft 41 .

Please refer to FIG. 1 and FIG. 5 in conjunction, the support plate 42 close to one end of the first casing 1 is rotatably connected to the first casing 1 through a rotating shaft 41 , and the other support plate 42 close to one end of the second casing 2 passes through another rotating shaft 41 is rotatably connected with the second housing 2 . When the first shell 1 and the second shell 2 move toward each other, the adjacent support plates 42 rotate around the corresponding rotating shafts 41, so that the support plates 42 are closed to each other and accommodated in the first shell 1 and the second shell 42. in the accommodating space jointly formed by the two shells 2 .

In this way, through the rotation of the support plate 42 around the rotating shaft 41, the size of the support member 4 when folded can be reduced, which can ensure that the support member 4 does not occupy too much physical space of the display device 100 when the support member 4 is folded, and thus can be saved The available physical space is used for the installation of other components, thereby improving the space utilization rate of the entire display device 100 and facilitating the thinning of the display device 100 .

During practical application, the inventor found that when the supporting plates 42 are folded together, they may be folded in the direction of the flexible screen 3, which will squeeze the flexible screen 3, so that the display device 100 switches from the second display state to the first display state At the same time, the flexible screen 3 appears bulge. In order to improve this technical problem, the inventor innovatively improved the structure around the support member 4 . As shown in FIG. 7 , one end of the first housing 1 is provided with a first limiting plate 17 extending in the direction of the second housing 2 , and one end of the second housing 2 is provided with a first limiting plate 17 extending in the direction of the first housing 1 the second limit plate 23.

Please continue to refer to FIG. 7 , the first limiting plate 17 is used to limit the supporting plates 42 close to one end of the first housing 1 when the supporting plates 42 are folded together, and the second limiting plate 23 is used to limit the supporting plates 42 when the supporting plates 42 are closed to each other. When the 42 are folded together, the support plate 42 close to one end of the second housing 2 is limited. In this way, the support plate 42 can be folded and folded toward the side away from the flexible screen 3, so as to avoid squeezing the flexible screen 3, thereby preventing the flexible screen 3 from bulging when the display device 100 switches from the second display state to the first display state .

In order to realize the cooperation between the first limiting plate 17 and the second limiting plate 23 and the corresponding support plates 42, please refer to FIG. The support plate 42 of the second housing 2 is improved. Wherein, the support plate 42 close to the first casing 1 is provided with a first groove 421 that matches the size of the first limiting plate 17 , and the support plate 42 close to the second casing 2 is provided with a second limiting plate 421 . The second groove 422 is adapted to the size of the plate 23 .

When the support plates 42 are spread out from each other, the first limiting plate 17 is embedded in the first groove 421 and the second limiting plate 23 is embedded in the second groove 422 . In this way, the flatness of the support plates 42 when they are unfolded can be ensured, so as to realize the support for the flexible screen 3 .

When the supporting plates 42 are folded together, the first limiting plate 17 and the second limiting plate 23 can abut against each other so as to be on the same plane as the first bearing surface 11 and the second bearing surface 21 . In this way, when the display device 100 is in the first display state, the first bearing surface 11 , the second bearing surface 21 , the first limiting plate 17 and the second limiting plate 23 can form a complete bearing surface for the flexible screen 3 Supporting can improve the problem that the flexible screen 3 is hollow and unsupported in the first display state of the display device 100 .

During the specific implementation, in order to realize the smooth switching of the display device 100 between the first display state and the second display state, please continue to refer to FIG. 1 and FIG. 2 , one end of the first casing 1 away from the second casing 2 is provided with The opening 111 is provided with the rolling element 6 , and the inner cavity 12 of the first housing 1 is provided with a movable connecting plate 14 . The flexible screen 3 is wound around the rolling element 6 and then 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 can be understood that when the first casing 1 and the second casing 2 move back, the flexible screen 3 stretches and drives the movable connecting plate 14 to move in the direction of the rolling element 6 in the inner cavity 12 . When the first casing 1 and the second casing 2 move toward each other, the movable connecting plate 14 drives the flexible screen 3 to partially extend into the inner cavity 12 along the rolling element 6 . In this way, by arranging the scroll member 6, the display size of the flexible screen 3 can be smoothly switched, thereby realizing the smooth switching of the display device 100 between the first display state and the second display state.

In practical application, in order to improve the connection stability between the flexible screen 3 and the movable connecting plate 14, please refer to FIG. The movable plate 142 is arranged between the inner bottom wall 151 of the first casing 1 and the inner top wall 152 of the first casing 1 , one end of the fixed plate 141 is fixedly connected with the movable plate 142 , and the other end extends toward the direction of the rolling element 6 . Wherein, the fixing plate 141 may be parallel to the first bearing surface 11 .

Further, an accommodating groove is formed between the fixed plate 141 , the movable plate 142 and the inner top wall 152 . The first end 31 of the flexible screen 3 extends into the accommodating groove and is fixedly connected with the fixing plate 141 and the movable plate 142 , and the fixing plate 141 is used to carry the part of the flexible screen 3 located in the accommodating groove. In this way, by fixing the first end 31 of the flexible screen 3 on the fixed plate 141 and the movable plate 142 , the connection stability between the flexible screen 3 and the movable connecting plate 14 can be improved.

In practical application, in order to ensure that the first casing 1 and the second casing 2 do not have positional deviation when sliding against each other, please continue to refer to FIG. 4 , the end of the first casing 1 close to the second casing 2 is provided with a A sliding part 16 is provided with a second sliding part 22 at one end of the second casing 2 close to the first casing 1 . The second sliding part 22 is sleeved on the first sliding part 16 to realize the sliding connection between the first casing 1 and the second casing 2 . In this 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 housing 1 and the second housing 2 will not be displaced when sliding against each other.

During the specific implementation, the inventor found that when the first casing 1 and the second casing 2 move toward each other to realize the contraction of the flexible screen 3, if the flexible screen 3 encounters resistance when extending into the first casing 1 (for example, The rolling element 6 is stuck), which will cause the flexible screen 3 to warp upward as shown in FIG. 9 during the shrinking process, so that it is difficult to realize the effective shrinkage of the flexible screen 3, which will affect the display effect of the flexible screen 3 and the display device. 100 for normal use.

In order to improve the technical problem of upward warping of the flexible screen 3 during the shrinking process, please refer to FIG. 4 in combination, 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 the end of the first casing 1 close to the second casing 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 can 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, so as to ensure the flatness of the flexible screen 3 .

Please continue to refer to FIG. 4 , when the first housing 1 and the second housing 2 move back, the flexible screen 3 drives the movable plate 142 to move close to the rolling member 6 in the inner cavity 12 , and the movable plate 142 applies force to the elastic member 5 through the movable plate 142 . The pulling force further stretches the elastic member 5 to accumulate elastic potential energy. When the first casing 1 and the second casing 2 move toward each other, the elastic member 5 releases the elastic potential energy and drives the flexible screen 3 to move in the direction of the first sliding part 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, so as to avoid upward warping of the flexible screen 3 during the shrinking process. It can be understood that by arranging the elastic member 5, it can be ensured that the flexible screen 3 maintains tension continuously during the expansion and contraction process, thereby preventing the flexible screen 3 from wrinkling during the expansion and contraction process.

In practical application, in order to realize the locking of the display device 100 in the second display state, please refer to FIG. 4 and FIG. 10 in combination. , and the other end extends into the second shell 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, so as to realize the locking of the display device 100 in the second display state. In addition, when the locking member 7 releases the locking of the first casing 1 and the second casing 2 , the first casing 1 and the second casing 2 move toward each other to realize the contraction of the flexible screen 3 .

In this embodiment, the locking member 7 may be a locking lever. As shown in FIG. 10 , the locking piece 7 can be ejected from the second housing 2 when the first housing 1 and the second housing 2 move back (for example, ejected to a certain angle in the Y direction in FIG. 11 ), and then combined with The second casing 2 is against each other. In this way, the elastic member 5 cannot drive the flexible screen 3 to shrink, and thus cannot indirectly drive the first casing 1 and the second casing 2 to move toward each other, so that the first casing 1 and the second casing 2 can be locked.

In addition, the locking of the first casing 1 and the second casing 2 can also be released by acting on the locking member 7 . For example, the locking of the first casing 1 and the second casing 2 can be released by pressing the locking member 7. When the first casing 1 and the second casing 2 move towards each other to realize the retraction of the flexible screen 3, the locking member 7 can extend into a pre-opened space in the second housing 2 for accommodating the locking member 7 .

In this embodiment, since the flexible screen 3 is only carried but not fixed on the first bearing surface 11, in order to ensure that the flexible screen 3 does not wrinkle during use, in an alternative embodiment, the flexible screen 3 is located at The area of the second bearing surface 21 is attached and fixed to the second bearing surface 21 . In this way, the bonding and fixing area between the flexible screen 3 and the second bearing surface 21 can be maximized, so as to ensure the stability of the flexible screen 3 on the first bearing surface 11 and the second bearing surface 21, and prevent the flexible screen 3 from Wrinkles appear during use.

In the specific implementation process, in order to achieve precise switching of the display screen of the flexible screen 3, please refer to FIG. 2 and FIG. 11 in combination, the display device 100 may further include a position sensor 8 disposed at the opening 111 and close to the scroll member 6, and a The processor 9 in the first casing 1 or the second casing 2 . The position sensor 8 is disposed at the opening 111 and close to the rolling element 6 to detect the position of the flexible screen 3 and send the detected position data to the processor 9 . The processor 9 can adjust the display parameters of the display device 100 according to the position data.

In this embodiment, the position data can be used to characterize the size of the flexible screen 3 , for example, the position data data1 can be used to characterize the size of the flexible screen 3 as a smaller display size, and the position data data2 can be used to characterize the size of the flexible screen 3 for larger display size. Further, the processor 9 can adjust parameters such as the resolution, refresh rate, and display brightness value of the flexible screen 3 according to different position data, so as to realize precise switching of the display screen of the flexible screen 3 .

Based on the above, the embodiments of the present invention describe the switching process of the display device 100 in different sizes of display states.

First, please refer to FIG. 1 , which is a schematic structural diagram of the display device 100 in a first display state. When the display device 100 needs to be switched from the first display state to the second display state, the first housing 1 and/or the second housing 2 can be acted on, so that the first housing 1 and the second housing 2 face away from each other sports. For example, the second shell 2 is relatively static as an example for illustration. When the first shell 1 and the second shell 2 move backwards, the first shell 1 can move away from the second shell along the X direction shown in FIG. 1 . body 2 , thereby driving the flexible screen 3 to extend and unfold around the rolling element 6 .

Next, please refer to FIG. 1 and FIG. 3 in combination, when the first housing 1 moves away from the second housing 2 along the X direction, the support 4 is deployed between the first housing 1 and the second housing 2 . The flexible screen 3 extends from the first casing 1 along the -X direction around the rolling element 6 and is carried on the first bearing surface 11 , so as to realize the adjustment and increase of the display size of the flexible screen 3 . In addition, the flexible screen 3 also drives the movable connecting plate 14 to move toward the direction close to the rolling element 6 to stretch the elastic element 5 . At the same time, the locking member 7 gradually protrudes from the second housing 2 .

Finally, please refer to FIG. 1 , FIG. 3 and FIG. 4 , when the supporting member 4 is fully unfolded, the locking member 7 protrudes from the second housing 2 and abuts between the first housing 1 and the second housing 2 between. At this time, the fully unfolded support 4 can support the area of the flexible screen 3 located at the gap 13 between the first housing 1 and the second housing 2, so as to complete the display device 100 from the first display state to the second display state state switching.

Optionally, if the display device 100 needs to be switched from the second display state to the first display state, the locking member 7 can be acted on to release the locking of the first casing 1 and the second casing 2, and then act on the first casing 1 and the second casing 2. The casing 1 and/or the second casing 2 make the first casing 1 and the second casing 2 move toward each other and approach each other, and the elastic member 5 releases the elastic potential energy and drives the flexible screen 3 to retract the first casing through the movable connecting plate 14.
