[0077] In the following description, suffixes "module", "part", or "unit" used for components are merely intended for facilitating description of the present application, and do not have specific meanings or functions thereof.

[0078] In the embodiment, the smart terminal with flexible screen, such as a mobile phone, has the same size as a conventional mobile phone in the folded state and can be conveniently carried, and has a larger display area in the unfolded state. When the smart terminal is folded, the flexible screen is also folded synchronously, needs to be bent by 180°, and has a certain arc at the bending position.

[0079] Since the flexible screen cannot be pulled or squeezed, otherwise it is easy to cause damage and failure, the length of the flexible screen cannot change when the smart terminal is unfolded and folded, and the traditional hinge structure cannot meet the functional requirements, thereby affecting the service life of the smart terminal.

[0080] In view of the above background, the hinge device provided by the application is carried by at least two supporting plates. Since the two adjacent supporting plates are hinged around the hinge shaft as the hinge center, the projection of the flexible screen and the projection of the hinge shaft at least partially coincide in the axial direction of the hinge shaft, so that the hinge shaft and the flexible screen are at the same thickness position. Therefore, when the folding angle of the hinge device changes, the squeezing and pulling effect on the flexible screen can be reduced, the size of the flexible screen can be ensured to remain unchanged, and the service life can be improved.

[0081] The hinge device and the smart terminal provided by the embodiment of the application are described below with reference to the accompanying drawings.

[0082] First embodiment

[0083] Reference Figure 1 As shown in the drawings, the application provides a hinge device, which comprises: at least two supporting plates 110, the at least two supporting plates 110 are arranged along a target direction, and two adjacent supporting plates 110 are hinged by a hinge shaft 130; the supporting plate 110 has a bearing surface, the bearing surface is connected with the flexible screen, and the axis of the hinge shaft 130 is located on one side of the bearing surface; in the axial direction of the hinge shaft 130, the projection of the flexible screen and the projection of the hinge shaft 130 at least partially coincide, so that the size of the flexible screen is consistent in the unfolded state and the folded state of the hinge device.

[0084] Optionally, the bearing surface is used to fix the flexible screen, the target direction is indicated by the arrow X in the drawing, and the arrow Y in the drawing indicates the axial direction of the hinge shaft 130. Figure 1 Figure 1

[0085] ​​Optionally, the hinge device is provided by the present application, at least two supporting plates 110 are arranged in a hinged manner, and the flexible screen is carried by the at least two supporting plates 110, and the flexible screen is driven to unfold and fold by the supporting plates 110. Since the two adjacent supporting plates 110 are hinged around the hinge shaft 130 as the hinge center, in the axial direction of the hinge shaft 130, the projection of the flexible screen at least partially overlaps the projection of the hinge shaft 130, so that the hinge shaft 130 is in the same thickness position of the flexible screen, the center of rotation of the flexible screen coincides with the flexible screen, so that when the folding angle of the hinge device changes, the extrusion and pulling effect on the flexible screen can be reduced, the size of the flexible screen is ensured to remain unchanged, and the service life is improved.

[0086] Optionally, the flexible screen is used for displaying images, and the flexible screen includes but is not limited to being bonded to the carrying surface through an adhesive layer.

[0087] In a possible implementation manner, the flexible screen can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro organic light-emitting diode display screen, or a quantum dot light emitting diode (QLED) display screen.

[0088] Reference Figure 6 As shown, the thickness direction is the direction indicated by the arrow Z, and the hinge shaft 130 is in the same thickness position as the flexible screen. It can be that the central axis of the hinge shaft 130 coincides with the flexible screen, or the outer peripheral surface of the hinge shaft 130 is tangent to or intersects with the flexible screen, so that during the folding and unfolding of the hinge device, the distance between the center of rotation of the flexible screen and the central axis of the hinge shaft 130 is small or coincides, thereby avoiding the flexible screen from being pulled or extruded, and ensuring the service life of the flexible screen.

[0089] The flexible screen can be unfolded or folded along with the hinge device. Reference Figure 1 、 Figure 22 and Figure 23 As shown, when the hinge device is in a flat state, the flexible screen is in a flat state and can have a larger display area to improve the viewing experience of the user. Reference Figure 2 ,Figure 24 and Figure 25 As shown in FIGS. 1, 2, 3 and 4, when the hinge device is in the folded state, the flexible screen is also in the folded state, thereby presenting a smaller length or width dimension, being compact and portable, and being convenient for storage and transportation.

[0090] Optionally, the hinge device provided by the present application is characterized in that the two ends of the two adjacent supporting plates 110 are hingedly connected to each other through different hinge shafts 130, the hinge shaft 130 is a solid shaft, the structure is simple, the connection strength is high, the installation precision is accurate, and the stability of the hinge connection between the supporting plates 110 is improved.

[0091] In one possible implementation, referring to FIGS. 1, 2, 3 and 4, the supporting plate 110 includes a supporting plate body 111 and a hinge block 112 connected to the two ends of the supporting plate body 111, and the hinge shaft 130 is arranged in the hinge block 112 to hingedly connect the two adjacent supporting plates 110 to each other. Figure 4 and Figure 5 In one possible implementation, referring to FIGS. 1, 2, 3 and 4, the supporting plate 110 includes a supporting plate body 111 and a hinge block 112 connected to the two ends of the supporting plate body 111, and the hinge shaft 130 is arranged in the hinge block 112 to hingedly connect the two adjacent supporting plates 110 to each other.

[0092] In one possible implementation, the supporting plate body 111 and the hinge block 112 can be an integral whole, the connection strength is high, two mounting holes 1122 are arranged in the hinge block 112, and one hinge shaft 130 is arranged in each of the two mounting holes 1122 to hingedly connect the two adjacent supporting plates 110 to each other.

[0094] In one possible implementation, the bearing surface is arranged on the supporting plate body 111, and the bearing surface can be a circular arc surface.

[0095] In one possible implementation, the supporting plate body 111 includes a plurality of segments connected in sequence, and the plurality of segments can be connected in sequence along the axis direction of the hinge shaft 130, and each of the adjacent segments can be connected through a screw.

[0096] In one possible implementation, the hinge block 112 and the two adjacent hinge blocks 112 are hingedly connected to each other through two hinge shafts 130, respectively.

[0097] In one possible implementation, in order to make the hinge device more smooth between the two adjacent supporting plates 110 in the folded state, and to avoid local position arching, the number of the supporting plates 110 is at least three.

[0098] In one possible implementation, the number of the supporting plates 110 arranged side by side along the target direction can be three, and optionally, the number of the supporting plates 110 can also be four or five, so as to avoid the occurrence of undesirable phenomena such as creases and wrinkles on the flexible screen.

[0099] In a possible implementation, referring to Figure 4 and Figure 5 , the hinge blocks 112 of the mutually spaced pallets 110 are arranged in a row along the arrangement direction of the plurality of pallets 110. Such a structure can avoid mutual interference between the hinge blocks 112 when switching between the unfolded state and the folded state of the hinge device.

[0100] In a possible implementation, the hinge block 112 has a limiting portion 1121. In the unfolded state, the limiting portion 1121 of the hinge block 112 abuts against the adjacent hinge block 112 to prevent reverse folding of the pallet 110. The limiting portion 1121 functions as a limiting portion, and the limiting portion 1121 can be a protruding block that can abut against the adjacent hinge block 112.

Such a structure allows the support member 120 to be hinged at both ends of the plurality of pallets 110 along the target direction and to move synchronously.

[0105] In a possible implementation, referring to Figure 9As shown, the support plate 121 and the connecting portion 122 can be an integral whole, which is beneficial to improve the structural strength of the support 120. The connecting portion 122 is provided with a connecting hole 1221, which can be a circular hole. The connecting hole 1221 and the mounting hole 1122 are penetrated by the hinge shaft 130, so as to realize the rotation cooperation between the connecting portion 122, the hinge block 112 and the hinge shaft 130.

[0106] Reference Figure 4 As shown, in the unfolded state, the support plate 121 is flush with the plurality of supporting plates 110, so as to better support the flexible screen, so that the flexible screen is more flat, which is beneficial to improve the user experience.

[0109] In a possible implementation manner, reference Figure 17 and Figure 19 As shown, the two decorative members 220 are arranged on the two sides of the fixing member 210 in a swingable manner, so that in the unfolded state of the hinge device, the two decorative members 220 are located in the same plane, and reference Figure 10 As shown, in the folded state of the hinge device, the two decorative members 220 are located in two different planes which are parallel to each other.

[0110] In a possible implementation manner, reference Figure 18 and Figure 21 As shown, the fixing member 210 can be two, and the two fixing members 210 are arranged at intervals. The decorative member 220 is movably arranged on the two sides of the two fixing members 210, which can improve the stability of the connection between the decorative member 220 and the fixing member 210.

[0111] In a possible implementation, as shown in Figure 5 When the number of the supporting plates 110 is odd, for example, 3 or 5, the fixing member 210 can be fixedly connected to the supporting plate 110 arranged in the middle position. When the number of the supporting plates 110 is even, for example, 4 or 6, the fixing member 210 can be fixedly connected to the two supporting plates 110 arranged in the middle position. Alternatively, the fixing member 210 can be fixedly connected by welding, adhesive bonding, or screw connection.

[0112] In a possible implementation, when the number of the supporting plates 110 is 3, the supporting plates 110 at the two ends in the target direction are each hingedly connected to two supporting members 120. In this way, the two sides of the hinge device each have 4 hinging shafts 130, and when the hinge device is in the folded state, the 4 hinging shafts 130 can evenly divide the 180° arc into 6 arc segments each having a central angle of 30°, so that the flexible screen can present a smooth arc in the folded position during folding, thereby achieving 180° folding and avoiding the occurrence of folds.

[0113] In a possible implementation, the decorative member 220 can be a decorative plate, which plays a role of aesthetics and decoration.

[0114] In a possible implementation, as shown in Figure 3 and Figure 12 The decorative member 220 is provided with a avoiding slot 223 in which the fixing member 210 is located. One end of the fixing member 210 is provided with a sliding slot 212, and the decorative member 220 is provided with a sliding column 224 slidingly arranged in the sliding slot 212.

[0115] As shown in Figure 10 When the hinge device is in the folded state, the sliding column 224 slides to one end of the sliding slot 212, and when the hinge device is in the unfolded state, the sliding column 224 slides to the other end of the sliding slot 212. Since the two decorative members 220 are relatively swingably arranged at the two sides of the fixing member 210, the decorative member 220 swings around the sliding column 224, and the sliding column 224 can move in the sliding slot 212, so that the swing center of the two decorative members 220 can be adjusted during the relative swinging of the two decorative members 220, so that the structure of the folding assembly 200 is compact and interference with the movement of the supporting plate 110 is avoided.

[0116] In a possible implementation, the sliding slot 212 is arc-shaped, and the centers of the two sliding slots 212 are away from each other.

Figure 3 and Figure 12 As shown, it includes: a fixing member 210 and at least two decorative members 220, the decorative members 220 being movably disposed on both sides of the fixing member 210; when the hinge device is in the unfolded state, at least two decorative members 220 are located on the same plane; when the hinge device is in the folded state, at least two decorative members 220 are located on two mutually parallel planes.

[0136] In one possible implementation, the two decorative elements 220 are pivotally disposed on either side of the fixing element 210 such that when the hinge is extended, the two decorative elements 220 are located in the same plane, and when the hinge is folded, the two decorative elements 220 are located in two different planes that are parallel to each other.

[0137] The present invention provides a hinge device for the side facing away from the flexible screen. Since the two decorative parts 220 are swayably arranged on both sides of the fixing part 210, a good shielding effect can be achieved through the fixing part 210 and the two decorative parts 220 during the process of changing the folding angle, thereby improving the integrity of the appearance surface.

The elastic element 400 is used to compress the decorative element 220 to limit the gap between the two decorative elements 220. This ensures that there are no large gaps between the two decorative elements 220 and between the two decorative elements 220 and the fixing element 210, thus ensuring a relatively complete appearance of the hinge device and achieving self-concealing of the appearance.

[0144] In a possible implementation, the elastic force direction of the elastic member 400 points to the decorative member 220 and the swing member 300. By the elastic member 400 applying an elastic pushing force to the decorative member 220, the gap between the two decorative members 220 can be prevented from being too large when the folding angle of the hinge device changes, so that a better shielding effect is achieved, and the structure of the folding assembly 200 is compact.
