Referring to fig. 1 and fig. 2 together, a flexible display device 100 according to a first embodiment of the present invention includes a flexible display panel 10, a hinge structure 20, and a hinge guard structure 30. The hinge structure 20 is arranged between the flexible display panel 10 and the hinge guard structure 30. The hinge structure 20 is used for supporting the flexible display panel 10, and the hinge protection structure 30 is used for protecting the hinge structure 20, so as to avoid the problem that the appearance of the flexible display device 100 is affected due to the exposed hinge structure 20, and the problems of being difficult to prevent dust and clamping hands are solved.

As shown in fig. 2 and 3, a hinge structure 20 according to an embodiment of the present invention is schematically shown. The hinge structure 20 includes a plurality of link plates 21 hinged to each other, the hinge guard structure 30 includes a guard cover 31 connected to at least one link plate 21, and the guard cover 31 covers the plurality of link plates 21.
Alternatively, in the present embodiment, the protecting cover 31 is directly fixedly connected to the link plate 21 by means of attachment. In other embodiments, the protecting cover 31 may be connected with the link plate 21 by other mounting structures. Preferably, in the embodiment, the hinge guard structure 30 further includes a bracket 32, the guard cover 31 and the plurality of link plates 21 are fixedly connected by the bracket 32, and the guard cover 31 covers the bracket 32 and the plurality of link plates 21.
In the present embodiment, as shown in fig. 2 and 3, each link plate 21 includes a first exposed surface 211 and two opposite side surfaces 212. The first surface 211 of the link plate 21 is an end surface near the hinge guard structure 30. The protecting cover 31 covers at least one bracket 32 and the first surface 211 and two side surfaces 212 of the link plate 21, so as to prevent dust and other impurities from entering the hinge structure 20, and solve the problem of hand clamping of the hinge structure 20 during deformation. Each link plate 21 also includes a second surface 210 (shown in fig. 5) opposite the first surface 211. The second surface 210 of each link plate 21 is contoured to form a smooth curved surface when the hinge mechanism 20 is bent.
As shown in fig. 3, each link plate 21 has a receiving slot 2111 on a side facing the hinge guard structure 30. Specifically, the first surface 211 of each link plate 21 is provided with a receiving groove 2111 for receiving the bracket 32 along the length direction. It will be appreciated that the length direction is perpendicular to the direction in which the hinge structure 20 bends. In the present embodiment, the housing groove 2111 penetrates both side surfaces 212 of the link plate 21. It is understood that in other embodiments, the accommodating groove 2111 may not extend through the two side surfaces 212 of the link plate 21.
It can be understood that, in the present embodiment, the number of the brackets 32 is the same as the number of the link plates 21, that is, the brackets 32 include a plurality of brackets, and one bracket 32 is disposed for each link plate 21. In other embodiments, the number of brackets 32 may be set by the user according to actual needs. For example, when there is only one bracket 32, the bracket 32 is preferably provided at the link plate 21 located at or near the center of the hinge structure 20. Wherein, the bottom surface of the housing slot 2111 of each chain plate 21 is provided with a plurality of first grooves 2112 arranged at intervals. The first grooves 2112 are communicated with the accommodating grooves 2111. Specifically, the first grooves 2112 are disposed at the bottom 2110 of the accommodating groove 2111. Optionally, the first grooves 2112 are symmetrically distributed from the center line of the hinge structure 20 to ensure flatness of the protecting cover 31, and the protecting cover 31 is stressed uniformly during deformation of the hinge structure 20.
In this embodiment, the side surface 212 of the link plate 21 includes a first side surface 2121, a second side surface 2122, and a limiting step surface 2123 connecting the first side surface 2121 and the second side surface 2122. The limiting step surface 2123 is used for limiting the protective cover 31 and the bracket 32. Optionally, a first accommodating space 213 is formed between two adjacent chain plates 21 on a side close to the hinge guard structure 30. The first accommodating space 213 is used for providing a bending space when the protecting cover 31 is in the deformed state.
In the present embodiment, the hinge structure 20 further includes a plurality of shafts 22, a plurality of locking members 23, and two base frames 24 opposite to each other. The two adjacent link plates 21 are hinged by the rotating shaft 22, so that the deformation of the hinge structure 30 is realized to drive the deformation of the flexible display panel 10. Each locking piece 23 is disposed between two adjacent link plates 21 and is locked on the rotating shaft 22, so as to define the movement space of the link plates 21. Specifically, two locking members 23 are correspondingly connected to two opposite ends of each rotating shaft 22, so that the adjacent two link plates 21 are restricted from moving in the axial direction of the rotating shaft 22, and therefore the adjacent two link plates 21 can only move in the radial direction of the rotating shaft 22. It is understood that the axial direction of the rotation shaft 22 refers to the length direction of the rotation shaft 22, and the radial direction of the rotation shaft 22 refers to a direction perpendicular to the length direction of the rotation shaft 22. A plurality of link plates 21 connect the two base frames 24. The two link plates 21 adjacent to the two base frames 24 are fixedly connected to the corresponding base frames 24, respectively.
Each of the locking members 23 includes a connecting portion 231 and a stopper portion 232. The connecting portion 231 extends perpendicularly outward from the middle of the stopper portion 232. The connecting portion 231 has a substantially cylindrical shape. The connecting portion 231 of the locking member 23 is fixedly connected to the rotating shaft 22. The position-limiting portion 232 abuts against the second side face 2122 of the link plate 21, so that a gap is formed between the position-limiting portion 232 of the locking member 23 and the first side face 2121 of the link plate 21, thereby limiting the position of the protecting cover 31 and the bracket 32.
In the present embodiment, the plurality of link plates 21 includes two first link plates 25 and a plurality of second link plates 26 that are opposite to each other. The second link plates 26 are sandwiched between the first link plates 25, and the first link plates 25 are fixedly connected to the corresponding base frames 24, respectively. The first link plate 25 has two fixing plates 251 extending from one side thereof adjacent to the base frame 24. The two ends of the first chain plate 25 are provided with a plurality of connecting blocks 252 protruding from one side far away from the base frame 24. Each connecting block 252 is axially provided with a shaft hole 2521 for receiving the rotating shaft 22 to realize the rotation of the two adjacent link plates 21. The second link plate 26 has a similar structure to the first link plate 25, except that the second link plate 26 has a symmetrical structure, i.e., the second link plates 26 are symmetrically arranged from the center line. Specifically, the second link plate 26 has a plurality of connecting blocks 262 protruding towards both sides of the two first link plates 21, and each connecting block 262 has a shaft hole 2621 along the axial direction for accommodating the rotating shaft 22. The connecting blocks 262 of two adjacent second link plates 26 are staggered to facilitate the rotating shaft 22 to movably connect two adjacent second link plates 26. It will be appreciated that the connecting block 252 of the first link plate 25 and the connecting block 262 of the second link plate 26 adjacent to the first link plate 25 are also offset to allow the movable connection of the first link plate 25 and the second link plate 26. Each base frame 24 has an end near the first link plate 25 with a slot 241 for receiving two fixing plates 251 of the first link plate 25.
In the present embodiment, referring to fig. 2, 4, 6 and 7, the protecting cover 31 includes a cover plate 311 and two opposite side plates 312. The cover 311 and the two side plates 312 together enclose a housing space 313 for housing the bracket 32. Two side plates 312 extend perpendicularly outward from both ends of the cover plate 311.
The cover 311 is substantially rectangular. The cover 311 includes a plurality of alternately arranged fixing portions 3111 and deformable portions 3112. The fixing portion 3111 of the cover plate 311 can be directly fixedly connected with the link plate 21. Specifically, in the present embodiment, the fixing portion 3111 of the cover 311 is fixedly connected to the link plate 21 through the bracket 32. The deformation portion 3112 of the cover plate 311 is directly opposite to the first accommodating space 213 defined by the two adjacent link plates 21, that is, the cover plate 311 is disposed corresponding to the first accommodating space 213. The fixing portion 3111 of the cover plate 311 is attached to the bracket 32, and the deformation portion 3112 of the cover plate 311 is accommodated in the first accommodating space 213 formed between two adjacent link plates 21 when the hinge structure 20 is bent. When the hinge structure 20 is unfolded, the fixing portion 3111 and the deformation portion 3112 are located on the same plane. The deformable portion 3112 extends into the first accommodating space 213 when the hinge structure 20 is bent, and is located outside the first accommodating space 213 when the hinge structure 20 is unfolded. The deformation portion 3112 extends into the first receiving space 213 to form a protrusion 3113.
Each side plate 312 defines an opening 3121 through which the locking member 23 passes. The opening 3121 is substantially semicircular. Each side panel 312 includes opposing medial and lateral sides 3122, 3123. In this embodiment, the inner side surface 3122 of the protective cover 31 directly faces the first side surface 2121 of the link plate 21, and the outer side surface 3123 of the protective cover 31 is flush with the second side surface 2122 of the link plate 21, so that the flexible display device 100 forms a regular surface, thereby improving the overall appearance of the flexible display device 100 and preventing dust from entering.
As shown in fig. 2 and 4, in the present embodiment, the bracket 32 is interposed between the link plate 21 and the barrier cover 31, and is fixedly provided on the link plate 21 of the hinge structure 20. Preferably, the brackets 32 are arranged at equal intervals, and two adjacent brackets 32 are arranged in parallel, or the brackets 32 are symmetrically distributed from the central line of the hinge structure 20, so as to ensure the flatness of the protecting cover 31, and the protecting cover 31 is stressed uniformly during the deformation of the hinge structure 20. The bracket 32 includes a connecting plate 321 and two opposite positioning blocks 322, and the two positioning blocks 322 extend perpendicularly and outwardly from two ends of the connecting plate 321. The fixing portion 3111 of the cover 311 is directly opposite to the connection plate 321 of the bracket 32. The coupling plate 321 of the bracket 32 is fitted into the receiving groove 2111 of the link plate 21. The web 321 of the bracket 32 is generally elongate. The distance between the two positioning blocks 322 is greater than or equal to the length of the accommodating groove 2111, so that the connecting plate 321 of the bracket 32 is accommodated in the accommodating groove 2111. The side of the connecting plate 321 away from the protecting cover 31 is provided with a plurality of second grooves 3211 arranged at intervals. The second groove 3211 of the bracket 32 is directly opposite to the first groove 2112 of the link plate 21. The two opposite sides of each positioning block 322 are provided with arc-shaped notches 3221, and the positioning blocks 322 of two adjacent brackets 32 form a gap 3222 at the notch 3221 for the locking member 23 to pass through. Each positioning block 322 is provided with two opposite inclined surfaces 3223 from a side close to the connecting plate 321. The two adjacent inclined surfaces 3223 of the two positioning blocks 322 jointly enclose a second accommodating space 3224 for accommodating the deformation portion 3112 of the protecting cover 31. The two inclined surfaces 3223 are inclined toward the extending direction of the positioning block 322, so that the hinge mechanism 20 provides a bending space for the deformation portion 3112 of the shield cover 31 when deformed.
In the present embodiment, at least one bracket 32 is interposed between the guard cover 31 and the link plate 21, and the at least one bracket 32 is fixedly disposed on the link plate 21 of the hinge structure 20. The hinge guard structure 30 further comprises a mounting structure 33. The mounting structure 33 is fixedly or detachably attached to the link plate 21 and the bracket 32. The mounting structure 33 is sandwiched between the first groove 2112 of the link plate 21 and the second groove 3211 of the bracket 32. In the present embodiment, the mounting structure 33 is a magnetic adsorption structure. The mounting structure 33 includes a plurality of adsorbed bodies 331 and a plurality of adsorbed bodies 332, each adsorbed body 331 is correspondingly accommodated in the second slot 3211 or the first slot 2112, and each adsorbed body 332 is correspondingly accommodated in the first slot 2112 or the second slot 3211. The adsorbent 332 is, for example, a magnet. The adsorbed material 331 is an object containing iron, cobalt, and nickel components, such as tinplate. The shapes of the plurality of adsorbed bodies 331 and the plurality of adsorbed bodies 332 are, for example, but not limited to, rectangular, circular or other polygonal shapes. Preferably, the plurality of adsorbed bodies 331 and the plurality of adsorbed bodies 332 are selected from regularly shaped bodies.
Alternatively, each of the absorbing bodies 332 and the corresponding absorbed body 331 are disposed in an overlapping manner. Specifically, the adsorbed body 331 has two first end surfaces 3311 which are opposite and flat, the adsorbing body 332 also has two second end surfaces 3321 which are opposite and flat, and the shape and the size of the first end surfaces 3311 are the same as those of the second end surfaces 3321, so that the contact area between the adsorbed body 331 and the adsorbing body 332 is increased, and the adsorption force between the two is increased.
It will be appreciated that in other embodiments, the mounting structure 33 may also be a slide guide structure or a locking structure (e.g., a screw). In the embodiment, the plurality of adsorbed bodies 331 are attached in the second groove 3211 of the bracket 32, and the plurality of adsorbed bodies 332 are attached in the first groove 2112 of the chain plate 21. Optionally, the thickness of the adsorbed object 331 is the same as the depth of the second groove 3211, so that when the adsorbed object 331 is accommodated in the second accommodating groove 3211, a side of the bracket 32 facing away from the protecting cover 31 forms a flat surface. The thickness of the absorber 332 is the same as the depth of the first groove 2112, so that when the absorber 332 is accommodated in the first groove 2112, the absorber 332 faces the second end surface 3321 of the protecting cover 31 and forms a flat surface with the groove bottom 2110 of the accommodating groove 2111 of the link plate 21, so as to facilitate the mounting of the bracket 32 on the link plate 21.
Preferably, the thickness of the adsorbed body 331 is smaller than that of the adsorbed body 332, so that cost is saved and the coupling force between the bracket 32 and the link plate 21 can be strengthened. In other embodiments, the thickness of the adsorbed body 331 and the depth of the second groove 3211 may be different, and the thickness of the adsorbed body 332 and the depth of the first groove 2112 may also be different. Preferably, the sum of the thicknesses of the attracted body 331 and the attracted body 332 is equal to the sum of the depths of the first notch 2112 and the second notch 3211 to facilitate the installation of the bracket 32.
In the present embodiment, the protective cover 31 and the bracket 32 are both made of a flexible material. Flexible materials such as, but not limited to, flexible transparent plastics, flexible glass or metal foils, other resilient materials capable of bending are suitable for use in the present invention. In this embodiment, the flexible material is preferably an organic polymer. Examples of organic polymers include, but are not limited to, Polyimide (PI), Polyamide (PA), Polycarbonate (PC), Polyethersulfone (PES), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polymethyl methacrylate (PMMA), or Cyclic Olefin Copolymer (COC).

The deformed portion 3112 of the protecting cover 31 faces the first accommodating space 213 formed between two adjacent link plates 21.
During assembly, the adsorbed body 331 is attached to the second groove 3211 of the bracket 32, and the adsorbed body 332 is attached to the first groove 2112 of the chain plate 21. The connecting plate 321 of the bracket 32 is accommodated in the accommodating groove 2111 of the link plate 21, and the two positioning blocks 322 of the bracket 32 are correspondingly abutted against the two limit step surfaces 2123 of the link plate 21. At this time, the attracted body 331 and the attracted body 332 attract each other, thereby achieving the fixed connection between the bracket 32 and the link plate 21. Subsequently, the fixing portion 3111 of the protective cover 31 is attached to the connection plate 321 of the bracket 32, thereby achieving the fixed connection between the bracket 32 and the protective cover 31. Further, the locking member 23 passes through the opening 3121 of the protecting cover 31 and the gap 3222 formed between the positioning blocks 322 of the two adjacent brackets 32 and is locked to the rotating shaft 22, so that the fixed connection between the hinge protecting structure 30 and the hinge structure 20 can be further enhanced.
