Abstract
Description
Technical Field

[0002] Scalable flexible display devices can adjust the screen display area according to the user's needs and are widely used in intelligent terminals, such as in the front row of vehicles.
[0003] Existing flexible display devices typically include a mounting frame and a flexible display screen. The mounting frame has a first mounting position and a second mounting position, which are arranged at an angle. The first end of the flexible display screen is slidably mounted on the first mounting position, and the second end of the flexible display screen is slidably mounted on the second mounting position and hidden within the mounting frame. The first end of the flexible display screen is used for display. The mounting frame is equipped with two drive mechanisms, which typically use a motor to drive a lead screw to rotate, which in turn drives a nut to slide. The two drive mechanisms drive the first and second ends of the flexible display screen synchronously, thereby extending or retracting the first end of the flexible display screen and adjusting the display area. A drawback of existing flexible display devices is that they require two drive mechanisms to complete the extension and retraction adjustment of the flexible display screen, and the motors of the two drive mechanisms must work synchronously, making control difficult.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] In existing stretchable flexible display devices, to ensure synchronized sliding between the first end 200a and the second end 200b of the flexible display screen 200, both drive mechanisms require detection elements to measure their output stroke. Control requires real-time adjustment of the output of the two drive mechanisms based on the values detected by these elements, and synchronization of their start and stop speeds is crucial to prevent excessive relative sliding distance between the first end 200a and the second end 200b, which could lead to damage to the flexible display screen 200. This presents significant control challenges. Furthermore, each drive mechanism requires at least two motors 311. The more motors 311 there are, the higher the overall failure rate and the lower the reliability. If one motor 311 fails while the other operates normally, excessive relative sliding distance between the first end 200a and the second end 200b of the flexible display screen 200 can easily occur, causing the flexible display screen 200 to be pulled or squeezed against the mounting frame 100.
[0034] Reference Figures 1 to 4 According to a first aspect of the present invention, a retractable flexible display device includes a fixing frame 100, a flexible display screen 200, and a driving mechanism. The fixing frame 100 is provided with a first mounting position 121 and a second mounting position 131, which are arranged at an angle. A first end 200a of the flexible display screen 200 is slidably mounted on the first mounting position 121, and a second end 200b of the flexible display screen 200 is slidably mounted on the second mounting position 131. The driving mechanism includes a driving device 310 and a reversing structure. The driving device 310 is connected to the first end 200a and the second end 200b of the flexible display screen 200 via a pulling member 330. The reversing structure is disposed between the pulling member 330 and the fixing frame 100 and is used to reverse the pulling member 330 so that the driving device 310 can drive the pulling member 330 to drive the first end 200a and the second end 200b of the flexible display screen 200 to slide synchronously.
[0035] In the flexible display device provided by this utility model, the first end 200a and the second end 200b of the flexible display screen 200 are installed one-to-one on the first mounting position 121 and the second mounting position 131 of the fixing frame 100, so that the first end 200a and the second end 200b of the flexible display screen 200 form an angle, thereby the first end 200a or the second end 200b of the flexible display screen 200 can be used for display. The driving device 310 is connected to the first end 200a and the second end 200b of the flexible display screen 200 through the pulling member 330 and uses the reversing structure to reverse the direction of the pulling member 330, thereby enabling the driving device 310 to drive the flexible display screen 20 ... The device 310 can drive the pulling member 330 to move the first end 200a and the second end 200b of the flexible display screen 200 synchronously. With the above configuration, only one driving device 310 is needed to realize the synchronous sliding of the first end 200a and the second end 200b of the flexible display screen 200. There is no need to configure two driving mechanisms. For flexible display devices or vehicles and other equipment, only the start and stop of one driving device 310 is needed to control the sliding of the first end 200a and the second end 200b of the flexible display screen 200. The control is simpler and more convenient, and it is easier to adjust the extension and retraction speed of the flexible display screen 200 as needed.
[0036] The flexible display device provided by this utility model requires only one drive device 310 and a small number of motors 311. Since the pulling member 330 and the reversing structure are mechanical structures, their reliability is easily guaranteed. Therefore, the overall reliability of the flexible display device is high. Furthermore, even if the drive device 310 fails, the first end 200a and the second end 200b of the flexible display screen 200 will stop sliding synchronously, thereby avoiding damage to the flexible display screen 200 due to excessive relative sliding distance between the first end 200a and the second end 200b.
[0037] Furthermore, the flexible display device provided by this utility model only requires one driving device 310, which makes it easier to control costs and reduce manufacturing costs. Moreover, for a single driving device 310, it is easier to reduce operating noise and achieve silent expansion and contraction of the flexible display device.
[0038] In some embodiments, the flexible display device described above is designed for independent use. In this case, the flexible display device can be equipped with a control device electrically connected to the drive device 310 to control the operation of the drive mechanism. Of course, in other embodiments, when the flexible display device is used in vehicles, display cases, or other equipment, the flexible display device may not have an independent control device. In this case, the control system of the vehicle, display case, or other equipment can be electrically connected to the drive device 310, thereby allowing the operation of the drive mechanism to be controlled through the control system of the vehicle, display case, or other equipment.
[0039] Reference Figure 1 , Figure 3 and Figure 7 According to some embodiments of this utility model, a first connecting portion 221 is provided at the first end 200a of the flexible display screen 200, and a second connecting portion 231 is provided at the second end 200b of the flexible display screen 200. The reversing structure includes multiple reversing members 320, wherein two reversing members 320 are arranged one-to-one on opposite sides of the first connecting portion 221 along the moving direction of the first connecting portion 221, and two reversing members 320 are arranged one-to-one on opposite sides of the second connecting portion 231 along the moving direction of the second connecting portion 231. The pulling member 330 passes through all the reversing members 320 sequentially from the driving device 310 and returns to the driving device 310, and the pulling member 330 is connected to the first connecting portion 221 and the second connecting portion 231. With the above arrangement, when the driving device 310 drives the pulling member 330 to move, the pulling member 330 can drive the first end 200a and the second end 200b of the flexible display screen 200 to slide synchronously.
[0040] Reference Figure 1 and Figure 7 According to some embodiments of this utility model, two first connecting portions 221 are provided, and the two first connecting portions 221 are spaced apart along a direction perpendicular to the moving direction of the first connecting portions 221. Two second connecting portions 231 are provided, and the two second connecting portions 231 are spaced apart along a direction perpendicular to the moving direction of the second connecting portions 231. The driving device 310 and all the reversing members 320 are located between the two second connecting portions 231. With the above arrangement, the driving mechanism can more smoothly drive the first end 200a and the second end 200b of the flexible display screen 200 to slide.
[0041] Reference Figure 1 and Figure 3According to some embodiments of the present invention, the first connecting part 221 is connected to the pulling member 330 via the first slider 410, and the first slider 410 is slidably mounted on the fixed frame 100. The second connecting part 231 is connected to the pulling member 330 via the second slider 420, and the second slider 420 is slidably mounted on the fixed frame 100. In the extending direction of the pulling member 330, the pulling member 330 between the first slider 410 and the adjacent reversing member 320 moves along the moving direction of the first connecting part 221, and the pulling member 330 between the second slider 420 and the adjacent reversing member 320 moves along the moving direction of the second connecting part 231. Therefore, during the process of the drive device 310 driving the pull member 330 to move, the first slider 410 and the pull member 330 between the first slider 410 and the adjacent reversing member 320 move synchronously in the same direction, making the first slider 410 slide more smoothly. The second slider 420 and the pull member 330 between the second slider 420 and the adjacent reversing member 320 move synchronously in the same direction, making the second slider 420 slide more smoothly. Moreover, the pull member 330 is in a taut state during the movement, and the movement of each position on the pull member 330 is synchronous. Thus, the second slider 420 and the first slider 410 can slide synchronously better.
[0042] Reference Figure 1 and Figure 5 In the specific implementation process, the reversing component 320 includes a roller rotatably mounted on the fixed frame 100. When the pulling component 330 passes the roller, it can change direction. When the pulling component 330 moves, the roller can move with it, thereby reducing the friction force on the pulling component 330 when it moves and avoiding wear on the pulling component 330.
[0043] It is conceivable that the above-mentioned reversing structure can also adopt other configuration methods. For example, the reversing structure may include a reversing channel provided on the fixed frame 100, the pulling member 330 is movably provided in the reversing channel, the reversing channel smoothly transitions at the corner position, and the side wall of the reversing channel is provided with clearance openings at the moving positions of the first slider 410 and the second slider 420, so that the pulling member 330 can be connected with the first slider 410 and the second slider 420.
[0044] Reference Figure 1 and Figure 5According to some embodiments of the present invention, the driving device 310 includes a motor 311 and a reel 312 mounted on the fixed frame 100. The motor 311 and the reel 312 are connected in a transmission relationship. The motor 311 is used to drive the reel 312 to rotate. Two take-up grooves 3121 are provided at intervals on the outer periphery of the reel 312. The take-up grooves 3121 are arranged in a ring around the axis of the reel 312. The two ends of the pulling member 330 are installed in the two take-up grooves 3121 in a corresponding manner. The two ends of the pulling member 330 are wound around the reel 312 in opposite directions. Thus, when the motor 311 drives the reel 312 to rotate, the reel 312 releases one end of the pulling member 330 and simultaneously takes in the other end of the pulling member 330, thereby driving the pulling member 330 to move.
[0045] It should be noted that the aforementioned drive device 310 can also be configured in other ways. For example, the drive device 310 includes a motor 311 and two pressure rollers. In this case, the pulling member 330 is a ring-shaped component that passes between the two pressure rollers. The two pressure rollers cooperate with each other to abut the pulling member 330. Thus, the motor 311 drives the two pressure rollers to rotate and cooperate, thereby pushing the pulling member 330 to move.
[0046] In practice, the pulling member 330 can be formed by connecting multiple ropes sequentially, with adjacent ropes connected by corresponding first sliders 410 or second sliders 420. During implementation, when connecting the ropes to the first slider 410 or second slider 420, the ropes can be tightened simultaneously, ultimately ensuring that all positions of the pulling member 330 are in a taut state.
[0047] In other embodiments, the pulling member 330 may also be a single rope, belt, or the like. If cost is not a concern, the pulling member 330 may also be a chain, in which case the aforementioned reversing member 320 may be replaced by a sprocket.
[0048] Reference Figure 1 , Figure 3 and Figure 6According to some embodiments of the present invention, the fixing frame 100 includes a first cover 110, a first mounting plate 120 and a second mounting plate 130 arranged at an angle, a driving mechanism located between the first mounting plate 120 and the second mounting plate 130, a first mounting position 121 disposed on the side of the first mounting plate 120 away from the driving mechanism, a second mounting position 131 disposed on the side of the second mounting plate 130 away from the driving mechanism, the first cover 110 mounted on the side of the second mounting plate 130 away from the driving mechanism, the first cover 110 and the second mounting plate 130 enclosing each other to form a storage cavity 140, and the second end 200b of the flexible display device is located in the storage cavity 140. Therefore, the first end 200a of the flexible display screen 200 can be used for display, and the second end 200b of the flexible display screen 200 can be stored in the storage cavity 140. By driving the first end 200a and the second end 200b of the flexible display screen 200 to slide synchronously through the driving mechanism, the size of the first end 200a of the flexible display screen 200 can be adjusted, that is, the display area of the portrait display device can be adjusted.
[0049] In specific implementation, the mounting bracket 100 may also include a second cover, which is located between the first mounting plate 120 and the second mounting plate 130. The second cover is used to cover and conceal the various components of the drive mechanism.
[0050] In the specific implementation process, the first mounting plate 120 and the second mounting plate 130 can be integrally produced. Of course, the first mounting plate 120 and the second mounting plate 130 can also be produced separately.
[0051] Reference Figure 3 and Figure 7According to some embodiments of the present invention, the flexible display screen 200 includes a flexible display element 210, a first back plate 220 and a second back plate 230. A flexible support member 240 is connected between the first back plate 220 and the second back plate 230. One end of the flexible display element 210 is mounted on the first back plate 220, and the other end of the flexible display element 210 is mounted on the second back plate 230 or the end of the flexible support member 240 away from the first back plate 220. The first back plate 220 is slidably mounted on the first mounting plate 120 and connected to the pull member 330. The second back plate 230 is slidably mounted on the second mounting plate 130 and connected to the pull member 330. The flexible display element 210 is located on the side of the first back plate 220 away from the first mounting plate 120. The flexible support member 240 abuts against the flexible display element 210, the first mounting plate 120 and the second mounting plate 130. With the above configuration, the flexible support member 240, the first back plate 220, and the second back plate 230 can support the flexible display element 210, allowing the flexible display element 210 to withstand a certain amount of pressure. In addition, there will be no relative movement between the flexible display element 210 and the flexible support member 240, the first back plate 220, and the second back plate 230. The flexible support member 240, the first back plate 220, and the second back plate 230 can separate the flexible display element 210 from the first mounting plate 120 and the second mounting plate 130, thereby protecting the flexible display element 210 and preventing wear on the flexible display element 210.
[0052] Reference Figure 3 and Figure 7 According to some embodiments of this utility model, the flexible support member 240 includes multiple rotating joints 241. The first back plate 220, all the rotating joints 241, and the second back plate 230 are hinged in sequence. The rotating joints 241 are provided with cylindrical surfaces for supporting the flexible display element 210. Thus, the flexible support member 240 can be flexibly deformed and can effectively support the flexible display element 210.
[0053] Reference Figure 3 and Figure 7 According to some embodiments of the present invention, the first back plate 220 is provided with a first connecting part 221, the first mounting plate 120 is provided with a first guide groove 122, one end of the first connecting part 221 passes through the first guide groove 122 and is connected to the pulling member 330, the second back plate 230 is provided with a second connecting part 231, the second mounting plate 130 is provided with a second guide groove 132, one end of the second connecting part 231 passes through the second guide groove 132 and is connected to the pulling member 330. Thus, the first end 200a and the second end 200b of the flexible display screen 200 can slide more smoothly.
[0054] According to a second aspect embodiment of the present invention, a vehicle includes the aforementioned retractable flexible display device. By employing the aforementioned retractable flexible display device, only one drive device 310 is needed to achieve synchronous sliding extension and retraction of the first end 200a and the second end 200b of the flexible display screen 200, eliminating the need for two drive mechanisms. The sliding synchronization between the first end 200a and the second end 200b of the flexible display screen 200 is good, making control simpler and more convenient, and improving operational reliability.
[0055] It is conceivable that the flexible display device provided by this utility model can also be applied to other occasions, such as display cases.
[0056] The technical features of the above embodiments can be combined in any way.
