Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a flexible screen assembly and a display device. Background Art

[0002] With the development of science and technology and the advancement of semiconductor technology, flexible display screens that can be bent and rolled are becoming more and more popular. While meeting users' demand for large display screens, they can also facilitate the storage and carrying of display screens, making display devices thinner and easier to carry.

[0003] Since the flexible display screen is flexible, it is easy to deform under the action of external force or its own gravity after being unfolded, thereby changing the display state of the flexible screen and reducing the display effect of the flexible screen. In order to improve the supporting performance of the flexible screen after being unfolded, the prior art provides a flexible screen assembly, which includes a shell, a flexible screen, a scroll and a telescopic bracket. The flexible screen can be wound on the scroll and can be accommodated in the shell. The telescopic bracket is respectively connected to the shell and the flexible screen, so that when the flexible screen is unfolded, the telescopic bracket is in an extended state to support the flexible screen.

[0004] In the flexible screen assembly provided by the prior art, when the flexible screen is unfolded, the telescopic bracket is basically arranged parallel to the flexible screen. Although it can provide certain support for the flexible screen, since the end of the telescopic bracket extends long out of the shell, the bending moment applied to the telescopic bracket is large. The telescopic bracket is easily deformed and bent due to its own weight during long-term use, affecting the continued use of the telescopic bracket. Moreover, when the flexible screen is subjected to an external force perpendicular to it, the telescopic bracket is easily bent and deformed due to its low stiffness in the direction perpendicular to the display screen surface, thereby causing deformation of the flexible screen and affecting the display effect of the flexible screen assembly.

[0044] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] like Figure 1 and Figure 2As shown, this embodiment provides a flexible screen assembly, which includes a shell 3, a reel 4, a flexible screen 2 and a support assembly 1. The shell 3 has a accommodating cavity, and the reel 4 is rotatably installed in the accommodating cavity; the flexible screen 2 can be wound on the reel 4, and the flexible screen 2 has a rolled-up state in which it is rolled up and stored in the accommodating cavity and an unfolded state in which it is unfolded for use. The support assembly 1 is installed on the shell 3 and has a stored state and a supported state. When the flexible screen assembly is not in use, the flexible screen 2 is in a rolled-up state, and the support assembly 1 is in a stored state and is accommodated in the shell 3; when the flexible screen assembly is in use, the flexible screen 2 is in an unfolded state, the support assembly 1 extends out of the accommodating cavity and is in a supported state, and the flexible screen 2 is supported on the support assembly 1.

[0046] For the convenience of subsequent description, the winding axis direction of the scroll 4 is set as the first direction, the thickness direction of the flexible screen 2 after unfolding is set as the second direction, and the direction perpendicular to the first direction and the second direction is set as the third direction. It can be understood that the third direction is the extension direction of the flexible screen 2.

[0047] The support assembly 1 includes a reinforcing support member 11 and a support arm, wherein the support arm includes a first support arm 12 and a second support arm 13. The first end of the reinforcing support member 11 is hinged to the housing 3, and the first ends of the first support arm 12 and the second support arm 13 are both hinged to the second end of the reinforcing support member 11. The first support arm 12 and the second support arm 13 can be rotated to be coplanar with the upper surface to form a support surface, and the second end of the first support arm 12 extends in a direction away from the housing 3, and the second end of the second support arm 13 extends in a direction toward the housing 3. The reinforcing support member 11 is arranged at an angle to the support surface, and the unfolded flexible screen 2 is supported on the support surface.

[0048] The flexible screen assembly provided in the present embodiment is provided with a reinforcing support member 11 whose one end is hinged to the shell 3 and a first support arm 12 and a second support arm 13 hinged to the second end of the reinforcing support member 11. When the support assembly 1 is in a supporting state and the flexible screen 2 is in an unfolded state, since the reinforcing support member 11 is arranged at an angle to the flexible screen 2, the reinforcing support member 11 can increase the rigidity of the support assembly 1 in the second direction, thereby reducing the probability of deformation and bending of the support assembly 1 when subjected to a force in the second direction, improving the supporting performance of the support assembly 1 for the flexible screen 2, and ensuring the display effect of the flexible screen 2 when it is unfolded; furthermore, the support assembly 1 and the flexible screen 2 are separately arranged, so that the arrangement of the support assembly 1 will not affect the winding and unfolding of the flexible screen 2, thereby improving the smoothness and reliability of the retraction and unfolding of the flexible screen 2, and at the same time, whether the flexible screen 2 is fully extended or partially extended, it can be supported on the support assembly 1, thereby improving the flexibility of use of the flexible screen assembly.

[0049] like Figure 1 and Figure 2As shown, in order to improve the connection convenience between the support assembly 1 and the housing 3, the reinforcing support member 11 is preferably a telescopic rod, which can be telescopic along its extension direction, and when the support assembly 1 is in a supporting state, the telescopic rod is in an extended state, and when the support assembly 1 is in a storage state, the telescopic rod is in a retracted state. This arrangement can reduce the space occupied by the support assembly 1 and facilitate the storage of the support assembly 1 inside the housing 3.

[0050] Preferably, the rotation axis of the reinforcing support member 11 and the shell 3 is arranged along the first direction, and the end of the reinforcing support member 11 away from the flexible screen 2 is hinged to the shell 3, thereby improving the convenience of screwing the reinforcing support member 11 into or out of the shell 3 and reducing the probability of interference between the reinforcing support member 11 and the shell 3.

[0051] Furthermore, when the support assembly 1 is in the storage state, the reinforcing support member 11, the first support arm 12 and the second support arm 13 are all arranged along the second direction to reduce the volume of the support assembly 1 in the storage state, reduce the space occupied by the support assembly 1, and improve the storage performance of the support assembly 1 in the shell 3.

[0052] In another embodiment, the reinforcing support member 11 may be a non-telescopic rod. When the support assembly 1 is in the retracted state, the reinforcing support member 11 extends along a first direction. When the support assembly 1 is unfolded, the reinforcing support member 11 first rotates around the second direction until the reinforcing support member 11 extends along a third direction. Then, the reinforcing support member 11 rotates around the axis of the first direction until the reinforcing support member 11 is inclined relative to both the second direction and the third direction.

[0053] In another embodiment, the reinforcing support member 11 may also adopt a folding rod, which includes at least two rod segments hinged at the ends. When the support assembly 1 is in the storage state, at least two rod segments are folded. When the support assembly 1 is in the supporting state, two adjacent rod segments are unfolded to be located in the same straight line.

[0054] like Figure 2-Figure 4 As shown, the housing 3 is provided with an inlet and outlet 31 and a storage groove 32 on one side along the second direction, the flexible screen 2 is passed through the inlet and outlet 31, and is retracted into the accommodating cavity or extended to the outside of the housing 3 through the inlet and outlet 31, and the support assembly 1 in the storage state is stored in the storage groove 32. By providing the storage groove 32, the storage performance of the support assembly 1 can be improved, and the support assembly 1 in the storage state can be prevented from protruding outside the housing 3.

[0055] The storage groove 32 and the inlet and outlet 31 are preferably spaced apart in the second direction to prevent the support assembly from scratching the flexible screen 2 during the folding and unfolding process, thereby improving the reliability of the support assembly 1 and the flexible screen 2, and also preventing external impurities such as dust and water vapor from entering the interior of the shell 3 through the storage groove 32.

[0056] The storage groove 32 extends along the second direction, and the storage groove 32 and the accommodating cavity are spaced apart in the third direction, which can prevent the storage groove 32 from being connected to the accommodating cavity, thereby preventing external dust and impurities from entering the accommodating cavity through the storage groove 32, thereby improving the cleaning performance and use reliability of the flexible screen assembly; at the same time, it can also prevent the support assembly 1 from scratching the flexible screen 2.

[0057] The reinforcing support member 11 is preferably capable of two-stage telescopic expansion to simplify the structure of the reinforcing support member 11. The reinforcing support member 11 comprises a fixed portion 111 and a telescopic portion 112 that can be telescopic relative to the fixed portion 111. The fixed portion 111 is hinged to the housing 3, and the ends of the telescopic portion 112 are hinged to the first support arm 12 and the second support arm 13. In other embodiments, the reinforcing support member 11 may also be a multi-stage telescopic rod-shaped structure.

[0058] In one embodiment, the reinforcing support member 11 is a pure rod structure, and the telescopic portion 112 is manually telescoped relative to the fixed portion 111. In another embodiment, the reinforcing support member 11 is an electric push rod, the fixed shell of the electric push rod forms the fixed portion, and the telescopic rod of the electric push rod forms the telescopic portion. In yet another embodiment, the reinforcing support member 11 is a piston cylinder, the cylinder body of the piston cylinder forms the fixed portion, and the telescopic rod of the piston cylinder forms the telescopic portion.

[0059] like Figure 3 and Figure 4 As shown, in order to improve the connection convenience between the support arm and the reinforcing support member 11, preferably, when the support assembly 1 is in the supporting state, the first support arm 12 and the second support arm 13 both extend along the second direction, thereby ensuring that the second end of the second support arm 13 can extend to a position close to the shell 3 while shortening the required length of the second support arm 13. When the lengths of the first support arm 12 and the second support arm 13 are constant, the support length of the flexible screen 2 is maximized.

[0060] In other embodiments, one of the first support arm 12 and the second support arm 13 may extend along the second direction, and the other of the first support arm 12 and the second support arm 13 may be arranged obtusely relative to the second direction, and the angle between the first support arm 12 and the second support arm 13 may be an obtuse angle. In this arrangement, the support range of the flexible screen 2 can be increased.

[0061] The first support arm 12 and the second support arm 13 are preferably of equal length, so that when the support assembly 1 is in a supporting state, the second end of the reinforcing support member 11 is located exactly in the middle of the first support arm 12 and the second support arm 13, so that the reinforcing support member 11 supports the middle position of the flexible screen 2 along the length direction, further improving the supporting performance of the support assembly 1 and reducing the probability of deformation and bending of the support assembly 1.

[0062] The first support arm 12 and the second support arm 13 are preferably located on opposite sides of the reinforcing support member 11 along the first direction to facilitate the rotational connection between the first support arm 12 and the second support arm 13 and the reinforcing support member 11 and reduce the probability of interference between the first support arm 12 and the second support arm 13.

[0063] In one embodiment, the support assembly 1 further includes an arm rotation driving member, which is connected to the support arm to drive the first support arm 12 and the second support arm 13 to rotate, so that the movement of the entire support assembly 1 can be automated. The first support arm 12 and the second support arm 13 are preferably respectively provided with an arm rotation driving member to achieve independent movement of the first support arm 12 and the second support arm 13, so that when the flexible screen 2 is extended to a short length, only the second support arm 13 can be rotated to the supporting position.

[0064] Preferably, the first support arm 12 has a first support position and a second support position, and when the support assembly 1 is in the supporting state and the first support arm 12 is in the first support position, the first support arm 12 and the second support arm 13 are located on opposite sides of the reinforcing support member 11 along the third direction. When the support assembly 1 is in the supporting state and the first support arm 12 is in the second support position, the first support arm 12 and the second support arm 13 are located on the same side of the reinforcing support member 11, and the first support arm 12 and the second support arm 13 are arranged oppositely and spaced apart.

[0065] The above arrangement enables, when the flexible screen 2 is extended to a longer length, the first support arm 12 to be rotated to the first support position, at which time the first support arm 12 supports the side of the flexible screen 2 away from the shell 3, and the second support arm 13 supports the side of the flexible screen 2 close to the shell 3; when the flexible screen 2 is extended to a shorter length, the first support arm 12 to be rotated to the second support position, that is, the first support arm 12 and the second support arm 13 jointly support the flexible screen 2 located between the second end of the reinforcing support member 11 and the shell 3, thereby improving applicability.

[0066] In another embodiment, the support assembly 1 may not be provided with an arm rotation drive, that is, the first support arm 12 and the second support arm 13 may be rotated manually, thereby simplifying the structure of the support assembly 1 and the flexible screen assembly and reducing costs. Under this setting, preferably, a rotation limiting structure is provided at the first end of each support arm to limit the support arm to be able to be unfolded only to a support position parallel to the flexible screen 2 and to be fixed at the support position. The rotation limiting structure between the two relatively rotating rods can be set with reference to the prior art and will not be described in detail here.

[0067] like Figure 3 and Figure 4As shown, in order to improve the supporting effect of the flexible screen 2, at least two supporting components 1 are arranged at intervals along the first direction to increase the supporting area of ​​the flexible screen 2, and increase the force balance and supporting reliability of the flexible screen 2 in the first direction. Preferably, a supporting component 1 is respectively arranged on both sides of the housing 3 along the first direction, so that the side of the flexible screen 2 can be effectively supported by the supporting component 1, thereby improving the supporting effect and preventing the side of the flexible screen 2 from sagging.

[0068] In order to prevent the flexible screen 2 from detaching from the first support arm 12 and / or the second support arm 13 after being unfolded, preferably, when the flexible screen 2 is unfolded, the flexible screen 2 and the support arm are adsorbed together by electrostatic attraction or magnetic attraction. For example, an electromagnetic layer may be provided on the back of the flexible screen 2, and the electromagnetic layer is made of electromagnetic material, so that when the flexible screen 2 is powered on, the back of the flexible screen 2 is magnetic, and when the power is off, the electromagnetic layer is not magnetic. The two support arms are made of magnetic conductive material, or the support surfaces of the two support arms are provided with magnetic absorption layers made of magnetic conductive material, so that after the flexible screen 2 is unfolded, the electromagnetic layer and the magnetic absorption layer are attracted to achieve the adsorption of the flexible screen 2 and the support arm.

[0069] This embodiment further provides an electronic device, including the above-mentioned flexible screen assembly. The electronic device provided by this embodiment can ensure the display performance of the electronic device and improve the user experience of the electronic device by adopting the above-mentioned flexible screen assembly.

[0070] Embodiment 2

[0071] This embodiment provides a flexible screen assembly, and the flexible screen assembly provided in this embodiment is a further improvement based on the first embodiment. This embodiment will not repeat the same contents as the first embodiment.

[0072] In this embodiment, a pull rod is connected to the extended end of the flexible screen 2, and the lower surface of the pull rod is flush with the non-display surface of the flexible screen 2. The pull rod can be engaged with any one of the first support arm 12 and the second support arm 13. By providing the pull rod, after the flexible screen is unfolded, the flexible screen 2 can be kept in the unfolded state by engaging the pull rod with the first support arm 12 or the second support arm 13, thereby preventing the flexible screen 2 from detaching from the support assembly 1, improving the state stability of the flexible screen 2, and thus ensuring the display effect of the flexible screen 2.

[0073] Furthermore, a locking protrusion is provided on the pull rod, and a plurality of slots are provided along the length direction of the first support arm 12 and the second support arm 13, and the locking protrusion can be inserted into any of the slots. In this arrangement, the slot to be locked with the locking protrusion can be selected according to the extended length of the flexible screen 2, so as to ensure that the flexible screen 2 can be fixed in a plurality of extended lengths.

[0074] It is understandable that the cam can be provided on the lower surface of the pull rod, and in this case, the slot is provided on the support surface. In other embodiments, the two ends of the pull rod can extend out of the opposite sides of the flexible screen 2, and the two ends of the pull rod are provided with a cam protruding downward, and the first support arm 12 and the second support arm 13 are provided with the above-mentioned slot on the side wall perpendicular to the display surface.

[0075] Further, the pull rod extends along the second direction, and the cross section of the pull rod is L-shaped, that is, the pull plate includes a vertically connected connection part and a pulling part, the lower surface of the connection part is flush with the non-display surface of the flexible screen 2, and the height of the connection part along the second direction is less than or equal to the width of the inlet and outlet 31, and the width of the pulling part along the second direction is greater than the width of the inlet and outlet 31. That is, when the flexible screen 2 is in a rolled-up state, the connection part is inserted into the inlet and outlet 31, and the pulling part is located outside the inlet and outlet 31, which is convenient for the user to manually pull the flexible screen 2 and prevent the extended end of the flexible screen 2 from being separated from the inlet and outlet 31 and failing to smoothly extend out of the inlet and outlet 31; furthermore, the setting of the pulling part can also block the inlet and outlet 31 to prevent external dust or impurities from entering the accommodating cavity through the inlet and outlet 31.

[0076] This embodiment further provides an electronic device, including the above-mentioned flexible screen assembly. The electronic device provided by this embodiment can ensure the display performance of the electronic device and improve the user experience of the electronic device by adopting the above-mentioned flexible screen assembly.
