[0035] The present application provides a flexible display device and an electronic device, which will be described below with reference to the accompanying drawings. Figures 1 to 11 The embodiments of the flexible display device and the electronic device will be described.

[0036] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic diagram of a flexible display device in a rolled state according to an embodiment of the present application; Figure 2 is a structural schematic diagram of a flexible display device in an unfolded state according to an embodiment of the present application; Figure 3 is Figure 2 is a sectional structural diagram of an embodiment at A-A in

[0037] The flexible display device provided in the embodiment of the present application comprises: a flexible display panel 1; a bearing structure 2 arranged on a non-display side of the flexible display panel 1; a main body structure 3, one end of the bearing structure 2 being connected with the main body structure 3, and the bearing structure 2 and the flexible display panel 1 being capable of being wound on the main body structure 3 together; a buckle structure 4, one end of the bearing structure 2 and the flexible display panel 1 being connected on the same side; and a supporting rod 5 comprising opposite first and second ends D1 and D2; wherein the flexible display device comprises a winding state and an unfolding state, in the unfolding state, the first end D1 of the supporting rod 5 abuts against the main body structure 3, the second end D2 of the supporting rod 5 abuts against the buckle structure 4, and the extending direction of the supporting rod 5 intersects with the unfolding direction of the flexible display panel 1.

[0038] The flexible display device provided in the embodiment of the present application comprises the flexible display panel 1, the bearing structure 2, the main body structure 3, the buckle structure 4 and the supporting rod 5, the bearing structure 2 is arranged on the non-display side of the flexible display panel 1 to support the bearing flexible display panel 1, guarantee the flatness of the flexible display panel 1 in the unfolding state, and further improve the display effect of the flexible display panel 1. The buckle structure 4 can be connected and fixed with the flexible display panel 1 and the bearing structure 2 on one hand, and can effectively limit the supporting rod 5 in the process of the flexible display device from the winding state to the unfolding state on the other hand, so as to guarantee that the second end D2 of the supporting rod 5 can abut against the buckle structure 4, and then drive the bearing structure 2 and the flexible display panel 1 to unfold in the direction away from the main body structure 3 by the buckle structure 4. Meanwhile, in the unfolding state, the first end D1 of the supporting rod 5 abuts against the main body structure 3, the second end D2 of the supporting rod 5 abuts against the buckle structure 4, and the extending direction of the supporting rod 5 intersects with the unfolding direction of the flexible display panel 1, so as to keep the display part of the bearing structure 2 and the flexible display panel 1 flat by the supporting rod 5, maintain the unfolding state of the bearing structure 2 and the flexible display panel 1 by the supporting rod 5, improve the stability of the flexible display device in use, and improve the user experience.

[0039] In the embodiment, the flexible display panel 1 and the bearing structure 2 need to be wound on the main body structure 3 in the winding state, so the flexible display panel 1 and the bearing structure 2 are made of a material with certain bendability or elasticity. However, the bearing structure 2 is prone to elastic deformation under stress, and the deformation of the bearing structure 2 needs to be limited to keep the flexible display panel 1 flat in use. In the embodiment, the supporting rod 5 is arranged to abut against the buckle structure 4 in the unfolding state, and the action force of the supporting rod 5 is used to limit the bending and retraction of the bearing structure 2, so as to keep the unfolded bearing structure 2 and the flexible display panel 1 flat and guarantee the user experience.

[0040] Optionally, the first end D1 is movably connected with the main body structure 3, and the second end D2 of the support rod 5 is configured as a free end.

[0041] It should be noted that the extending direction of the support rod 5 intersects with the unfolding direction of the flexible display panel 1. The support rod 5 is generally a long strip-shaped rod body, and the extending direction of the support rod 5 can be understood as the extending direction of the central axis of the rod body. The extending direction of the support rod 5 intersects with the unfolding direction of the flexible display panel 1, which can be understood as that the support rod 5 is inclined at a certain angle with respect to the unfolding direction of the flexible display panel 1, so as to ensure that the support rod 5 can provide sufficient force for the flexible display panel 1 and maintain the unfolded state of the flexible display panel 1. The main body structure 3 specifically adopts a cylindrical winding drum structure, so as to wind the carrying structure 2 and the flexible display panel 1 together. In the curled state, the flexible display device occupies a smaller space and is more convenient to store. In the unfolded state, the flexible display panel 1 can be placed horizontally or vertically according to actual needs, so as to be suitable for different application scenarios.

[0042] Optionally, the main body structure 3 can be internally provided with a circuit board, a battery, a fan and the like, which can be specifically set according to actual needs and is not limited in particular.

[0043] The flexible display panel 1 provided by the embodiment of the application can be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) or a micro flat panel display panel (Micro-OLED or Micro-LED), and is not limited in particular.

[0044] In some optional embodiments, the carrying structure 2 includes an elastic plate body covering one side surface of the non-display side of the flexible display panel 1.

[0045] It can be understood that, since the carrying structure 2 needs to be wound together with the flexible display panel 1 on the main body structure 3 in addition to supporting and carrying the flexible display panel 1, in the embodiment, the carrying structure 2 adopts an elastic plate body capable of being elastically deformed. The material of the elastic plate body can be a metal material meeting the elastic deformation strength requirement and having high yield strength, and the high yield strength of the elastic plate body is used to ensure that the flexible display panel 1 can be flat from bending to unfolding.

[0046] For example, the elastic plate body includes a spring steel sheet. The spring steel sheet has good elasticity, and since it works in a dynamic load environment, the material for manufacturing the spring should mainly have high yield strength; not cause plastic deformation when bearing heavy load; have high fatigue strength, long service life under repeated load; and have sufficient toughness and plasticity to prevent sudden brittle fracture under impact force. Thus, it can meet the back and forth conversion of the flexible display device between the coiled state and the unfolded state, and ensure the service life of the flexible display device.

[0047] Optionally, the material of the bearing structure 2 includes at least one of 65Mn (manganese), silicon manganese alloy, silicon chromium alloy, chromium manganese alloy, chromium vanadium alloy, tungsten chromium vanadium alloy.

[0048] In some optional embodiments, the thickness of the bearing structure 2 ranges from 0.05mm to 0.2mm. It should be noted that the thickness of the bearing structure 2 is relatively thin to achieve the visual effect of the ultra-thin display part of the flexible display device after unfolding, and improve the user experience.

[0049] In some optional embodiments, at least part of the surface of the bearing structure 2 is covered with a protective layer.

[0050] Considering that the bearing structure 2 with too thin thickness can easily cause harm to the human body, the protective layer can be arranged on the surface of the bearing structure 2, especially the exposed part and the part easily contacted by the user, to avoid the bearing structure 2 from causing harm to the user during use, thereby improving the safety of the flexible display device. At the same time, the appearance of the flexible display device can also be beautified.

[0051] The protective layer can be in the form of encapsulation or coating, as long as it can protect the user from being harmed. For example, the material of the protective layer includes at least one of silicone, polyurethane, and rubber. Silicone, polyurethane, and rubber have certain elasticity and soft texture, and will not harm the user. Of course, the protective layer can also be made of other materials, and there is no special limitation.

[0052] Please refer to Figures 3 to 4 In some optional embodiments, the buckle structure 4 includes a connecting part 41 and a bending part 42 connected to each other, and a first groove K1 is formed between the connecting part 41 and the bending part 42; the flexible display panel 1 and one end of the bearing structure 2 on the same side are connected to the connecting part 41, and the second end D2 of the supporting rod 5 can extend into the first groove K1.

[0053] It should be noted that the flexible display panel 1 and the bearing structure 2 stacked together can be directly connected with the connecting portion 41 through bonding or the like, and in order to improve the stability of the fixing, a receiving groove can also be correspondingly arranged on the connecting portion 41, so that one end of the flexible display panel 1 and the bearing structure 2 are inserted into the receiving groove together for fixing.

[0054] In the process of the flexible display device from the rolled state to the unfolded state, the free end of the support rod 5 can be inserted into the first groove K1 to abut against the buckle structure 4, so as to ensure that the support rod 5 will not fall off from the first groove K1 in the unfolding process, thereby ensuring the structural stability of the flexible display device when it is converted from the rolled state to the unfolded state.

[0055] Optionally, as shown in Figure 4 The connecting portion 41 and the bending portion 42 of the buckle structure 4 form a structure similar to a "J" shape, so as to facilitate the stable abutment of the support rod 5 against the buckle structure 4. Of course, the buckle structure 4 can also adopt other structure forms, and there is no special limitation.

[0056] Further, in order to facilitate the accommodation of the support rod 5 in the rolled state, facilitate the placement of the flexible display device and improve the aesthetics of the flexible display device, please refer to Figures 5 to 6 In some optional embodiments, the surface of the main body structure 3 is provided with a second groove K2, and the support rod 5 can be accommodated into the second groove K2.

[0057] The second groove K2 can be arranged on the outer surface of the main body structure 3 close to the buckle structure 4, so that the support rod 5 can more conveniently abut against the buckle structure 4. The shape of the second groove K2 can match the shape of the support rod 5, for example, when the support rod 5 is in a cylindrical shape, the support rod 5 can be arranged in a long strip shape with an arc-shaped groove, so as to improve the stability of the support rod 5 when placed, and the size of the second groove K2 is usually slightly larger than that of the support rod 5, so as to facilitate the smooth entry of the support rod 5 into the second groove K2.

[0058] Considering that the support rod 5 needs to be accommodated into the second groove K2 in the rolled state, in order to ensure that the support rod 5 will not unfold outward from the second groove K2 in the rolled state, in some optional embodiments, the main body structure 3 is provided with a limiting piece 6 for limiting the second end D2, so as to limit the support rod 5 from unfolding outward from the second groove K2 in the rolled state.

[0059] Specifically, the limiting piece 6 can specifically block the side of the support rod 5 away from the second groove K2, so as to block the unfolding of the support rod 5, for example, the limiting piece 6 can be a stop block, or the limiting piece 6 can be a protruding structure arranged on the main body structure 3, which can be clamped into a groove of the support rod 5.

[0060] For example, please refer to Figure 7The limiting member 6 comprises an elastic buckle, the main body structural member 3 is provided with a third groove K3 matched with the elastic buckle, and the elastic buckle can be retracted into the third groove K3.

[0061] It should be noted that the elastic buckle can be retracted relative to the groove on the supporting rod 5 under force to release the clamping relationship between the elastic buckle and the groove, so that the supporting rod 5 can be unfolded outward from the second groove K2. In the curled state, the elastic buckle can extend into the groove to limit the movement of the supporting rod 5 by mutual clamping therebetween.

[0062] Optionally, the elastic buckle comprises a knob, a spring or the like, and the clamping of the elastic buckle and the groove is realized by using the elastic restoring force of the spring.

[0063] Considering that a power is also needed to drive the supporting rod 5 to unfold outward, in some optional embodiments, please refer to Figures 8 to 9 The first end D1 is rotationally connected to the main body structural member 3 through a torsional spring N, i.e. a torsion spring, which can store and release angular energy or fix a device statically by rotating a force arm around the axis of the spring body. In the embodiment, the torsional spring N can be rotated by a certain angle in advance to store angular energy, so as to provide sufficient torsion to the supporting rod 5, so that the supporting rod 5 can be unfolded outward, thereby providing upward pushing force to the buckle structural member 4 at the top, so as to straighten the bearing structural member 2 and the flexible display panel 1, and achieve the supporting effect.

[0064] Specifically, the torsional spring N can be a torsional spring N with an initial torsion angle of 120°. The torsion angle refers to the angle of rotation of the shell of the torsional spring N around the spiral core. Generally, the greater the torsion angle of the torsional spring N, the greater the torque, and vice versa. The size of the torque is directly proportional to the driving force that the torsional spring N can provide to the supporting rod 5.

[0065] Of course, the driving force provided to the supporting rod 5 by the torsional spring N is not limited to the above, and other components can also be used to provide driving force to the supporting rod 5, such as a motor, without special limitation.

[0066] Optionally, the flexible display device further comprises a switch structural member G connected to the limiting member 6, and the switch structural member G is used to control the unfolding of the supporting rod 5 outward from the second groove K2.

[0067] The switch structural member G can be arranged on the surface of the main body structural member 3 for the convenience of use by the user. The switch structural member G can be a sliding switch, and the user can adjust the position of the limiting member 6 by sliding the switch structural member G, so as to control whether the limiting member 6 is clamped in the groove of the supporting rod 5, thereby controlling the unfolding of the supporting rod 5 outward from the second groove K2.

[0068] In some optional embodiments, during the process from the flat state to the unfolded state, the support rod 5 abuts against the first position of the buckle structure 4, and the first position is between one-third length and one-half length of the buckle structure in the extending direction of the buckle structure.

[0069] It can be understood that, by abutting the support rod 5 against the buckle structure 4 at one-third length to one-half length of the buckle structure, i.e., abutting the support rod 5 against the middle region of the buckle structure 4, the stability of the support rod 5 to the buckle structure 4 and the bearing structure 2 and the flexible display panel 1 supported by the bearing structure 2 can be ensured, and the problem that the support rod 5 may retract, the bearing structure 2 and the flexible display panel 1 may retract when subjected to an external force due to the abutment of the support rod 5 against the edge of the buckle structure 4 can be avoided, and the use reliability of the flexible display device is improved.

[0070] Correspondingly, when the support rod 5 abuts against the first position of the buckle structure 4, the included angle between the central axis of the support rod 5 and the central axis of the main body structure 3 is 60°-80°, so that the support rod 5 can provide sufficient supporting force while maintaining its stability.

[0071] Please refer to Figures 10 to 11 In some optional embodiments, the flexible display device further comprises a fourth slot K4 provided on the main body structure 3, and the buckle structure 4 can be clamped in the fourth slot K4 when the bearing structure 2 and the flexible display panel 1 are wound on the main body structure 3.

[0072] It should be noted that, since the support rod 5 does not need to abut against the buckle structure 4 in the curled state, the buckle structure 4 can be clamped in the fourth slot K4 of the main body structure 3, for example, the buckle structure 4 comprises a connecting portion 41 and a bent portion 42, and in the curled state, the bent portion 42 can be directly inserted into the fourth slot K4 to fix the bearing structure 2 and the flexible display panel 1 in the curled state, without the need for additional components, which simplifies the structure of the buckle structure 4 and facilitates preparation.
