DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0049] Figure 1 and Figure 2 is a schematic diagram of the structure of the display assembly provided by an embodiment of the present invention in a retracted state, Figure 3 and Figure 4 is a schematic diagram of the structure of the display assembly provided by an embodiment of the present invention in an expanded state, such as Figures 1 to 4 As shown, the display assembly includes a middle frame bracket 10, a display module 20, a sliding module 30 and a tensioning module 40; the middle frame bracket 10 includes a fixed middle frame 101, a first sliding middle frame 102 and a second sliding middle frame 103, the first sliding middle frame 102 and the second sliding middle frame 103 are respectively connected to the fixed middle frame 101, and the first sliding middle frame 102 and the second sliding middle frame 103 both slide in a direction close to or away from the fixed middle frame 101; the first end of the display module 20 is wound around the first sliding middle frame 102, and the display module 20 The first end of the display module 20 is wound around the second sliding middle frame 103, and the first end and the second end of the display module 20 are respectively fixed to the tensioning module 40; the tensioning module 40 is connected to the sliding and rolling module 30, the sliding and rolling module 30 and the middle frame bracket 10 are slidingly connected, and the sliding and rolling module 30 is fixedly connected to the first sliding middle frame 102 and the second sliding middle frame 103; the tensioning module 40 includes a tensioning wheel 401, and during the sliding of the first sliding middle frame 102 and the second sliding middle frame 103, the display module 20 is expanded or retracted along the rolling direction of the tensioning wheel 401.

[0050] Among them, the display module 20 is a display panel made of flexible material that can be deformed and bent. In an embodiment of the present invention, with the help of the bendable performance of the display module 20, the two ends of the display module 20 are bent and curled, and then accommodated in the inner cavity of the fixed middle frame 101, so that the first end and the second end of the display module 20 are in a stacked state in the fixed middle frame 101 to reduce the space occupied by the display module 20 in the fixed middle frame 101. When a larger display area is required, the display module 20 accommodated in the inner cavity of the fixed middle frame 101 is pulled out, that is, the display module 20 is unfolded, so that the display module 20 has a larger display area. When a larger display area is not required, the pulled-out display module 20 can be accommodated back in the inner cavity of the fixed middle frame 101 to achieve switching of different display areas.

[0051] The middle frame bracket 10 accommodated in the display module 20 is a main component for providing support for the display module 20 and for accommodating the display module 20. In the embodiment of the present invention, in order to meet the support requirements of the display module 20 when it is unfolded, the middle frame bracket 10 includes a fixed middle frame 101, a first sliding middle frame 102, and a second sliding middle frame 103. The first sliding middle frame 102 and the second sliding middle frame 103 are respectively connected to the fixed middle frame 101, and the first sliding middle frame 102 and the second sliding middle frame 103 both slide in a direction close to or away from the fixed middle frame 101. That is, when the display area of ​​the display module 20 needs to be increased, the first sliding middle frame 102 or the second sliding middle frame 103 is slid in a direction away from the fixed middle frame 101, or the first sliding middle frame 102 and the second sliding middle frame 103 are slid in a direction away from the fixed middle frame 101 at the same time, so that the first sliding middle frame 102 and the second sliding middle frame 103 are located on both sides of the fixed middle frame 101, so that the support area of ​​the middle frame bracket 10 is the sum of the support areas of the fixed middle frame 101, the first sliding middle frame 102 and the second sliding middle frame 103. On the contrary, when the display area of ​​the display module 20 does not need to be increased, the first sliding middle frame 102 or the second sliding middle frame 103 can be slid in a direction close to the fixed middle frame 101, or the first sliding middle frame 102 and the second sliding middle frame 103 can be slid in a direction close to the fixed middle frame 101 at the same time, so that the support area of ​​the middle frame bracket 10 is equal to the support area of ​​the fixed middle frame 101.

[0052] It should be noted that, in the embodiment of the present invention, since the first sliding middle frame 102 and the second sliding middle frame 103 both slide in a direction approaching or away from the fixed middle frame 101, and the first sliding middle frame 102 and the second sliding middle frame 103 are located on both sides of the fixed middle frame 101, when choosing to increase the display area of ​​the display module 20, you can choose to slide the first sliding middle frame 102 or the second sliding middle frame 103 according to different display requirements, or slide the first sliding middle frame 102 or the second sliding middle frame 103 at the same time, so that the method of increasing the display area of ​​the display component is more flexible, so that the adaptation range of the display component is increased.

[0053] In order to ensure that the tensioning force required for the display component when expanding and retracting is consistent, that is, the display module 20 is always in a "tightened state" when it is pulled out from the middle frame bracket 10 and retracted into the display module 20, in an embodiment of the present invention, the first end of the display module 20 is wound around the first sliding middle frame 102, and the first end of the display module 20 is wound around the second sliding middle frame 103, so that the display module 20 can change its position as the first sliding middle frame 102 and the second sliding middle frame 103 slide.

[0054] In an embodiment of the present invention, the tensioning module 40 is connected to the sliding module 30, the sliding module 30 and the middle frame bracket 10 are slidably connected, and the sliding module 30 is fixedly connected to the first sliding middle frame 102 and the second sliding middle frame 103. In this way, when the first sliding middle frame 102 and the second sliding middle frame 103 slide in the fixed middle frame 101, the tensioning module 40 is driven to slide. Since the first end and the second end of the display module 20 are respectively fixed on the tensioning module 40, the display module 20 slides. Furthermore, since the tensioning module 40 includes a tensioning wheel 401, during the sliding of the first sliding middle frame 102 and the second sliding middle frame 103, the display module 20 is expanded or retracted along the rolling direction of the tensioning wheel 401. Therefore, during the sliding of the display module 20, under the action of the tensioning wheel 401, the display module 20 is always in a taut state, and the tensioning force applied to the display module 20 when expanded or retracted is consistent, thereby avoiding damage to the display component and extending the service life of the display component.

[0055] Specifically, Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the sliding module 30 includes a first slider 301, a second slider 302, a third slider 303, and a fourth slider 304, and the tensioning module 40 includes a tensioning wheel 401, a tensioning belt 402, a first tensioning plate 403, and a second tensioning plate 404; the first tensioning plate 403 is fixed on the second slider 302, and the second tensioning plate 404 is fixed on the fourth slider 304, and the first end of the display module 20 is wound around the first sliding middle frame 102 and fixed on the second tensioning plate 404, and the second end of the display module 20 is wound around the second sliding middle frame 103 is fixed on the first tensioning plate 403, the tensioning wheel 401 is installed on the third slider 303, one end of the tensioning belt 402 is fixedly connected to the fixed middle frame 101, and the other end of the tensioning belt 402 is wound around the tensioning wheel 401 and fixedly connected to the fourth slider 304; the first slider 301 is fixedly connected to the first sliding middle frame 102, the third slider 303 is fixedly connected to the second sliding middle frame 103, and the first slider 301, the second slider 302, the third slider 303, and the fourth slider 304 are respectively slidably connected to the fixed middle frame 101.

[0056] It should be noted that the first slider 301, the second slider 302, the third slider 303 and the fourth slider 304 are all square blocks. When connected, the first tensioning plate 403 can be fixed to the second slider 302 by welding, screwing, bonding, etc., the second tensioning plate 404 can be fixed to the fourth slider 304 by welding, screwing, bonding, etc., the first end of the display module 20 is wound around the first sliding middle frame 102 and fixed to the first tensioning plate 403, and the second end of the display module 20 is wound around the second sliding middle frame 103 and fixed to the second tensioning plate 404, so that the display module 20 can move with the movement of the first tensioning plate 403 and the second tensioning plate 404.

[0057] Because the tensioning wheel 401 is installed on the third slider 303, one end of the tensioning belt 402 can be fixed to the fixed middle frame 101 by bonding, welding, etc., and the other end of the tensioning belt 402 can be wound around the tensioning wheel 401 and fixedly connected to the fourth slider 304, that is, one end of the tensioning belt 402 can change position as the fourth slider 304 slides, that is, under the pulling of the fourth slider 304, the tensioning belt 402 can change around the tensioning wheel 401 along the rolling direction of the tensioning wheel 401.

[0058] Since the first slider 301 is fixedly connected to the first sliding middle frame 102, the third slider 303 is fixedly connected to the second sliding middle frame 103, the first slider 301, the second slider 302, the third slider 303, and the fourth slider 304 are respectively slidably connected to the fixed middle frame 101, so that when the first sliding middle frame 102 slides toward or away from the fixed middle frame 101, it can drive the first slider 301 to slide, and when the second sliding middle frame 103 slides toward or away from the fixed middle frame 101, it can drive the third slider 303 to slide.

[0059] In this way, Fig. 9 As shown, when the display module 20 is unfolded, the first sliding middle frame 102 can slide in a direction away from the fixed middle frame 101, and the display module 20 is unfolded at the same time. Since the first tensioning plate 403 is fixed on the second slider 302, the first end of the display module 20 is wound around the first sliding middle frame 102 and fixed on the first tensioning plate 403, the second tensioning plate 404 slides, thereby driving the fourth slider 304 connected to the second tensioning plate 404 to slide. Since the tensioning wheel 401 is installed on the third slider 303, one end of the tensioning belt 402 is fixedly connected to the fixed middle frame 101, and the other end of the tensioning belt 402 is wound around the tensioning wheel 401 and fixedly connected to the fourth slider 304, the tensioning belt 402 can always provide a fixed tensioning force to the second tensioning plate 404 during the sliding process, so that the display module 20 remains in a taut state when unfolded. The sliding away of the second sliding middle frame 103 is consistent with the sliding principle of the first sliding middle frame 102, and the embodiment of the present invention will not be repeated.

[0060] On the contrary, Figure 8 As shown, when the display module 20 retracts, the first sliding middle frame 102 can slide in a direction close to the fixed middle frame 101, and the display module 20 can be retracted into the cavity of the fixed middle frame 101. Since the first tensioning plate 403 is fixed on the second slider 302, the first end of the display module 20 is wound around the first sliding middle frame 102 and fixed on the first tensioning plate 403, the second tensioning plate 404 slides, thereby driving the fourth slider 304 connected to the second tensioning plate 404 to slide. Since the tensioning wheel 401 is installed on the third slider 303, one end of the tensioning belt 402 is fixedly connected to the fixed middle frame 101, and the other end of the tensioning belt 402 is wound around the tensioning wheel 401 and fixedly connected to the fourth slider 304, the tensioning belt 402 can always provide a fixed tensioning force to the second tensioning plate 404 during the sliding process, so that the display module 20 can also remain in a taut state when retracted.

[0061] In addition, in order to reduce the production cost of display components, such as Figure 7 As shown, when the display assembly further includes a circuit board 50 and a touch chip 60 , optionally, the circuit board 50 and the touch chip 60 are fixed on the first tensioning plate 403 or the second tensioning plate 404 .

[0062] It should be noted that since the circuit board 50 and the touch chip 60 are fixed on the first tensioning plate 403 or the second tensioning plate 404, there is no need to additionally set a carrier for fixing the circuit board 50 and the touch chip 60 when setting the circuit board 50 and the touch chip 60. Therefore, the production cost of the display component can be reduced, and the circuit board 50 and the touch chip 60 can be hidden inside the middle frame bracket 10, so that a large frame will not be exposed at the edge of the display component, which is beneficial to improving the yield rate of display component manufacturing.

[0063] Optionally, to facilitate the connection of the slider, the fixed middle frame 101 includes a support plate 1011 and two opposing sliding plates 1012; the two sliding plates 1012 are arranged at both ends of the support plate 1011, and the inner surface of the sliding plate 1012 is provided with a first sliding groove 10111, a second sliding groove 10112, a third sliding groove 10113 and a fourth sliding groove 10114; the third slider 303 is slidingly connected to the first sliding groove 10111, the first slider 301 is slidingly connected to the second sliding groove 10112, the second slider 302 is slidingly connected to the third sliding groove 10113, and the fourth slider 304 is slidingly connected to the fourth sliding groove 10114, wherein the distances between the first sliding groove 10111, the second sliding groove 10112, the third sliding groove 10113, the fourth sliding groove 10114 and the sliding plate 1012 decrease successively.

[0064] It should be noted that the first slide groove 10111, the second slide groove 10112, the third slide groove 10113, and the fourth slide groove 10114 all extend along the sliding direction of the first sliding middle frame 102 and the sliding direction of the second sliding middle frame 103, so that the sliding direction of the third slider 303 in the first slide groove 10111 is consistent with the sliding direction of the first sliding middle frame 102 and the sliding direction of the second sliding middle frame 103, the sliding direction of the first slider 301 in the second slide groove 10112 is consistent with the sliding direction of the first sliding middle frame 102 and the sliding direction of the second sliding middle frame 103, the sliding direction of the second slider 302 in the third slide groove 10113 is consistent with the sliding direction of the first sliding middle frame 102 and the sliding direction of the second sliding middle frame 103, and the sliding direction of the fourth slider 304 in the fourth slide groove 10114 is consistent with the sliding direction of the first sliding middle frame 102 and the sliding direction of the second sliding middle frame 103. In this way, when the display module 20 is expanded and retracted, the movement of the entire mechanism is relatively compact, which can ensure the continuity and smoothness of the entire movement process.

[0065] In addition, in order to ensure that the display module 20 is always supported during the unfolding and retracting process, the sliding and rolling device also includes a first roller 305 and a second roller 306; the first roller 305 is hinged on the first sliding middle frame 102, and the second roller 306 is hinged on the second sliding middle frame 103, and the first end of the display module 20 is wound on the first roller 305, and the second end of the display module 20 is wound on the second roller 306.

[0066] It should be noted that the rolling direction of the first roller 305, the sliding direction of the second roller 306 and the movement direction of the display module 20 are consistent, so that the display module 20 slides around the rotation axis of the first roller 305 and the rotation axis of the second roller 306 when expanding and retracting. Since the first roller 305 is hinged on the first sliding middle frame 102, and the second roller 306 is hinged on the second sliding middle frame 103, the first end of the display module 20 is wound on the first roller 305, and the second end of the display module 20 is wound on the second roller 306. Therefore, the display module 20 always rolls close to the rolling surface of the first roller 305 and the rolling surface of the second roller 306 when expanding and retracting, which is more conducive to keeping the display module 20 taut when expanding and retracting. At the same time, the rolling surface of the first roller 305 and the second roller 306 can provide a larger support area for the display module 20, reduce the friction of the display module 20 when sliding, and thus reduce the damage to the display module 20 when sliding.

[0067] Specifically, the display component also includes a first rotating axis and a second rotating axis, the first sliding middle frame 102 includes a first supporting portion 1021 and two first mounting portions 1022, and the second sliding middle frame 103 includes a second supporting portion 1031 and two second mounting portions 1032; the first supporting portion 1021 is located between the two first mounting portions 1022, and the second supporting portion 1031 is located between the two first mounting portions 1022; the first roller 305 is hinged between the two first mounting portions 1022 through the first rotating axis, and the second roller 306 is hinged between the two second mounting portions 1032 through the second rotating axis.

[0068] It should be noted that, when the first roller 305 is hinged between the two first mounting parts 1022 through the first rotating axis, and the second roller 306 is hinged between the two second mounting parts 1032 through the second rotating axis, the first end of the display module 20 can be rolled up around the first rotating axis when unfolded and retracted, and the second end of the display module 20 can be rolled up around the first rotating axis when unfolded and retracted, so that the display module 20 can be rolled up at both ends, and thus can have a larger display area when unfolded.

[0069] In addition, in order to reduce the space occupied by the first sliding middle frame 102 and the second sliding middle frame 103 in the retracted state, optionally, as Fig.11 As shown, the first support portion 1021 includes a plurality of first support rods 10211 arranged at intervals. Fig.12 As shown, the second support part 1031 includes a plurality of second support rods 10311 arranged at intervals, wherein the length direction of the first support rod 10211 is perpendicular to the axis direction of the first rotating shaft, and the length direction of the second support rod 10311 is perpendicular to the axis direction of the second rotating shaft. In this way, the first support part 1021 includes a plurality of first support rods 10211 arranged at intervals, and the second support part 1031 includes a plurality of second support rods 10311 arranged at intervals to provide a relatively uniform support for the display module 20, so that the display module 20 can have a larger support area, which is conducive to the module remaining stable during the process of unfolding and retracting.

[0070] In addition, the spacing between each two adjacent first support rods 10211 is equal, and the spacing between each two adjacent second support rods 10311 is equal; when the display module 20 retracts around the sliding module 30, a second support rod 10311 is inserted between each two adjacent first support rods 10211, and a first support rod 10211 is inserted between two adjacent second support rods 10311 located at the ends of the second sliding middle frame 103.

[0071] In this embodiment, since there is a second support rod 10311 between every two adjacent first support rods 10211 when the display module 20 retracts around the sliding module 30, and a first support rod 10211 is inserted between two adjacent second support rods 10311 located at the ends of the second sliding middle frame 103, during the retraction of the display module 20, the second support rods 10311 and the first support rods 10211 are staggered, thereby saving the space occupied by the first sliding middle frame 102 and the second sliding middle frame 103 when retracting, making the entire structure more compact.

[0072] Further, such as Figure 5 As shown, a plurality of staggered first through grooves 10121 and second through grooves 10122 are provided on the support surface of the fixed middle frame 101; the first through grooves 10121 extend in a direction close to the second roller 306, and the second through grooves 10122 extend in a direction close to the first roller 305. When the display module 20 retracts around the sliding module 30, the first support rod 10211 is embedded in the first through groove 10121, and the second support rod 10311 is embedded in the second through groove 10122.

[0073] It should be noted that, when the display module 20 retracts around the scroll module 30, the first support rod 10211 is embedded in the first through slot 10121, and the second support rod 10311 is embedded in the second through slot 10122. Therefore, on the one hand, the sliding of the first sliding middle frame 102 can be limited by the first through slot 10121, and the sliding of the second sliding middle frame 103 can be limited by the second through slot 10122, so that the sliding of the entire assembly is more stable, and the first sliding middle frame 102 and the second sliding middle frame 103 are prevented from running off when sliding. On the other hand, the space occupied by the first sliding middle frame 102 and the second sliding middle frame 103 can be saved, making the layout of the entire assembly more compact.

[0074] Optionally, the display component also includes a first drive motor and a second drive motor, the first sliding middle frame 102 also includes a first rack 1023, and the second sliding middle frame 103 also includes a second rack 1033; the first rack 1023 is located on one side of the first support portion 1021, and the first rack 1023 is meshed with the drive gear of the first drive motor; the second rack 1033 is located on one side of the second support portion 1031, and the second rack 1033 is meshed with the drive gear of the second drive motor.

[0075] It should be noted that the driving shaft of the first driving motor is connected to the first gear, and the driving shaft of the second driving motor is connected to the second gear. In this way, when the display module 20 is expanded and retracted, the rotation of the first driving motor and the second driving motor can be controlled to rotate the first gear and the second gear. Since the first rack 1023 and the driving gear of the first driving motor are meshed, and the second rack 1033 and the driving gear of the second driving motor are meshed, the first sliding middle frame 102 and the second sliding middle frame 103 can be driven to slide, thereby driving the display module 20 to slide. Since the motor drive is more precise and stable, the control of the sliding of the display module 20 can be made more precise.

[0076] It can be seen from the above embodiments that in the embodiments of the present invention, since the tensioning module 40 is connected to the sliding module 30, the sliding module 30 and the middle frame bracket 10 are slidably connected, and the sliding module 30 is fixedly connected to the first sliding middle frame 102 and the second sliding middle frame 103. In this way, when the first sliding middle frame 102 and the second sliding middle frame 103 slide in the fixed middle frame 101, the tensioning module 40 is driven to slide. Since the first end and the second end of the display module 20 are respectively fixed on the tensioning module 40, the display module 20 can slide with the sliding of the first sliding middle frame 102 and the second sliding middle frame 103. Furthermore, since the tensioning module 40 includes a tensioning wheel 401, during the sliding of the first sliding middle frame 102 and the second sliding middle frame 103, the display module 20 is expanded or retracted along the rolling direction of the tensioning wheel 401. Therefore, during the sliding of the display module 20, under the action of the tensioning wheel 401, the display module 20 is always in a taut state, and the tensioning force applied to the display module 20 when expanded or retracted is consistent, thereby avoiding damage to the display component and extending the service life of the display component.

[0077] In addition, since the first tensioning plate 403 is fixed on the second slider 302, the second tensioning plate 404 is fixed on the fourth slider 304, the first end of the display module 20 is wound around the first sliding middle frame 102 and fixed on the second tensioning plate 404, the second end of the display module 20 is wound around the second sliding middle frame 103 and fixed on the first tensioning plate 403, the tensioning wheel 401 is installed on the third slider 303, one end of the tensioning belt 402 is fixedly connected to the fixed middle frame 101, and the other end of the tensioning belt 402 is wound around the tensioning wheel 401 and fixedly connected to the fourth slider 304, so that the first end and the second end of the display module 20 are stacked in the inner cavity of the fixed middle frame 101, making the structure of the entire display assembly more compact, and the current module can have a larger display area after unfolding.
