FIG. 4 is a three-dimensional schematic diagram of the hinge device and the elastic frame assembled together, and FIG. 5 is a schematic diagram of the hinge device and the elastic frame shown in FIG. 4 assembled together from another perspective. The bendable component 100 also includes an elastic frame 105, which is located between the back 1013 of the flexible element 101 (as shown in Figure 2-3) and the hinge device 103, and is used to support the flexible element 101 and improve the bendable element. The intensity of 100. The elastic frame 105 has a frame shape. The elastic frame 105 is fixed on the back 1013 of the flexible member 101 by an adhesive layer, and is arranged along the edge contour of the flexible member 101. The hinge device 103 is fixed to the side of the elastic frame 105 away from the flexible member 101 by a welding process. In this embodiment, the elastic frame 105 is a stainless steel frame; the number of hinge devices 103 is two, and each hinge device 103 is arranged along the longer side of the elastic frame 105, that is, each hinge device 103 is along the longer side of the flexible member 101. Set up.

It can be understood that the material of the elastic frame 105 is not limited. For example, the elastic frame 105 may be made of plastic material; the number of hinge devices 103 is not limited. For example, the number of hinge devices 103 may be one or more than two; The long side arrangement of 101 does not limit the setting area of the hinge device 103 and the flexible member 101. For example, the hinge device 103 can extend along the shorter side of the flexible member 101, and the hinge device 103 can maintain the flexible member 101 in a bent state or unfolded. The state is flat.

Specifically, please refer to FIGS. 6 and 7. FIG. 6 is a partial three-dimensional assembly diagram of a hinge device according to an embodiment of the present invention, and FIG. 7 is a three-dimensional exploded diagram of the hinge device shown in FIG. The hinge device 103 includes a plurality of hinge units 10 connected in sequence. Please refer to FIGS. 8 and 9. FIG. 8 is a three-dimensional assembly diagram of a hinge unit provided by an embodiment of the present invention, and FIG. 9 is a three-dimensional exploded diagram of the hinge unit shown in FIG. 8. Each hinge unit 10 includes a hinge member 11 and Elastic holding device 13. The hinge member 11 includes a hinge main body 113 and a connecting portion 115 protruding from one end of the hinge main body 113, and the other end of the hinge main body 113 is provided with a guide groove 1131. The elastic abutting device 13 is provided on the hinge main body 113.

Please refer to FIG. 10 in combination. FIG. 10 is a schematic diagram of two adjacent hinge units connected together. The connecting portion 115 includes a connecting shaft 1150. The connecting portion 115 of each hinge unit 10 is movably connected to the guide groove 1131 of the adjacent hinge unit 10 through the connecting shaft 1150 and resists the elastic abutment device 13 of the adjacent hinge unit 10. In this embodiment, the guide groove 1131 is arc-shaped, and the sliding track of the connecting portion 115 moving along the guide groove 1131 of the adjacent hinge unit 10 is an arc, so that two adjacent hinge units 10 are relatively bent to form an arc-shaped structure . In other words, the movement of the connecting shaft 1150 of the connecting portion 115 along the guide groove 1131 of the adjacent hinge unit 10 is a partial circular movement, so that the movement of the two adjacent hinge units 10 during the relative bending process is smoother. It is smooth, so that the bending process of the flexible member 101 is also smoother, which is beneficial to reduce the damage of the flexible member 101 due to bending, thereby prolonging the service life of the flexible member 101. Furthermore, through the sliding connection of the connecting shaft 1150 of the connecting part 115 with the guide groove 1131, the hinge units 10 can be relatively bent or flattened, which simplifies the structure of the hinge device 103 and facilitates the small size of the bendable assembly 100 Development. It can be understood that the shape of the guide groove 1131 is not limited. In addition, the relative bending or flattening of the hinge unit 10 in the present application refers to a change in the position between the hinge units 10.

Since the connecting portion 115 of each hinge unit 10 is connected to the guide groove 1131 of the adjacent hinge unit 10 and resists the elastic resisting device 13 of the adjacent hinge unit 10, the elastic force of the elastic resisting device 13 makes the adjacent The hinge unit 10 can remain relatively flat or bent, so that the bendable assembly 100 can switch between a bent state and a flat state. The so-called bent state is that at least a part of the flexible member 101 is bent relative to the rest; the so-called flattened state is that the front surface 1011 of the flexible member 101 is flat.

The hinge body 113 further includes a first end surface 1132, a second end surface 1133, a top surface 1134, and a bottom surface 1135. The first end surface 1132 and the second end surface 1133 are disposed opposite to each other, and the top surface 1134 and the bottom surface 1135 are disposed opposite to each other. The connecting portion 115 is protruded on the first end surface 1132. In this embodiment, the first end surface 1132 and the second end surface 1133 are both inclined with respect to the bottom surface 1135. The inclination angle of the first end surface 1132 with respect to the bottom surface 1135 is a first inclination angle α, and the inclination angle of the second end surface 1133 with respect to the bottom surface 1135 is a second inclination angle β, where the first inclination angle α is an acute angle, and the second inclination angle β is The obtuse angle is used to reduce the movable space when the hinge unit 10 is bent relative to the adjacent hinge unit 10, thereby facilitating the miniaturization of the hinge device 103. In other embodiments, the first inclination angle α is not limited to an acute angle, and the second inclination angle β is not limited to an obtuse angle.

In some embodiments, the first end surface 1132 of each hinge unit 10 and the second end surface 1135 of the adjacent hinge unit 10 can fit together well, so that two adjacent hinge units 10 can be relatively bent. Spliced together without gaps, thereby improving the support stability of the hinge device 103 to the flexible member 101. When the first end surface 1132 of the hinge unit 10 and the second end surface 1133 of the adjacent hinge unit 10 are attached together, the top surfaces 1134 of the two adjacent hinge units 10 are spliced to form a gapless surface, which is beneficial to the bending of the flexible member 101 When forming a smooth surface.

The top surface 1134 is disposed toward the flexible member 101. The top surface 1134 is protrudingly provided with a fixing protrusion 1137 for fixed connection with the elastic frame 105. Because the hinge unit 10 is fixedly connected to the side of the elastic frame 105 away from the flexible member 101 through the fixing protrusion 1137, a gap 107 is formed between the elastic frame 105 and the top surface 1134. The gap 107 can provide a suitable deformation space for the elastic frame 105 and the flexible member 101, and is beneficial for the elastic frame 105 and the flexible member 101 to release the stress caused by bending, thereby prolonging the service life of the elastic frame 105 and the flexible member 101. The top surface 1134 is a curved surface. In this embodiment, after each hinge unit 10 is relatively bent, the top surface 1134 of each hinge unit 10 can be spliced into a 180-degree arc structure, so that it can fit well with the flexible member 101, making the flexible member 101 It can also form a smooth arc surface, reduce damage to the flexible member 101 due to bending, and extend the service life of the flexible member 101. It can be understood that the top surface 1134 is not limited to a curved surface, and the top surface 1134 may also be a flat surface or other curved surfaces.

A receiving cavity 16 is defined on the hinge main body 113 for receiving the elastic holding device 13. The opening of the receiving cavity 16 extends from the opening of the second end surface 1133 to the bottom surface 1135. The receiving cavity 16 communicates with the guide groove 1131 to form a guide groove channel. The receiving cavity 16 extends in the horizontal direction. The horizontal direction is the extension direction of the two hinge units 10 when two adjacent hinge units 10 are relatively flat. The guide groove 1131 is formed on the side wall of the accommodating cavity 16. In this embodiment, the guide groove 1131 penetrates the side wall of the hinge main body 113, and the guide groove 1131 is used to movably connect with the connecting portion 115 of the adjacent hinge unit 10. The guide groove 1131 is inclined to the bottom surface 1135.

The elastic holding device 13 is received in the receiving cavity 16. The connecting portion 115 of each hinge unit 10 extends into the receiving cavity 16 of the adjacent hinge unit 10 and abuts against the elastic abutment device 13 of the adjacent hinge unit 10. Since the elastic abutment device 13 is contained in the accommodating cavity 16, the accommodating cavity 16 limits the telescopic movement of the elastic abutment device 13, which helps the hinge unit 10 to maintain smooth and stable movement relative to the adjacent hinge unit 10. This helps prevent the telescopic movement of the elastic abutment device 13 from being interfered by other structures of the bendable component 100.

The elastic resisting device 13 includes an elastic member 14 and a resisting block 15. In this embodiment, the elastic member 13 is a cylindrical spring. It can be understood that the elastic resisting device 13 may omit the resisting block 15; the elastic member 14 may also be other elastic structures, such as a torsion spring. The elastic member 14 and the resisting block 15 are both received in the receiving cavity 16, and the elastic member 14 is located on the side of the resisting block 15 away from the opening of the receiving cavity 16.

When the hinge unit 10 is flattened relative to the adjacent hinge unit 10 and is not subjected to external force, the resisting block 15 receives the elastic force of the elastic member 14 toward the opening direction of the receiving cavity 16, and the resisting block 15 is connected to the connecting portion 115 of the adjacent hinge unit 10 When resisting, the resisting block 15 stops in the guide groove channel, that is, the resisting block 15 can stop the movement of the connecting shaft 1150 of the adjacent hinge unit 10 along the guide groove 1131. In this embodiment, the abutting direction of the resisting block 15 and the connecting portion 115 of the adjacent hinge unit 10 is substantially parallel to the direction of the elastic force received by the resisting block 15. When the hinge unit 10 and the adjacent hinge unit 10 receive a force greater than the first threshold, the connecting portion 115 of the adjacent hinge unit 10 overcomes the elastic force of the elastic member 14, so that the resisting block 15 is forced toward the direction of the elastic member 14 Retraction makes the guide groove channel no longer be blocked by the resisting block 15 so that the connecting portion 115 of the adjacent hinge unit 10 slides along the guide groove 1131.

Since the opening of the receiving cavity 16 communicates with the guide groove 1131 to form a guide groove channel, when the resisting block 15 enters the guide groove channel, it can stop the movement of the connecting shaft 1150 of the adjacent hinge unit 10 along the guide groove 1131. The holding block 15 exits the guide groove channel, and the connecting shaft 1150 of the adjacent hinge unit 10 can move circularly along the guide groove 1131. This is beneficial to the hinge unit 10 to maintain a stable flat or bent state relative to the adjacent hinge unit 10. Convenient for users to use.

Furthermore, the resisting block 15 includes a sliding portion 151 and a resisting portion 153 protruding from one end of the sliding portion 151. One end of the sliding portion 151 away from the resisting portion 153 is connected to the elastic member 14. The other end of the resisting portion 153 away from the sliding portion 151 is used for resisting the connecting portion 115 of the adjacent hinge unit 10.

The resisting portion 153 includes a first side surface 1531, an end surface 1533 and a second side surface 1535, and the end surface 1533 is connected between the first side surface 1531 and the second side surface 1535. The first side surface 1531 and the second side surface 1535 are fixedly connected to the sliding portion 151, and the first side surface 1531 is provided on the side of the resisting portion 153 facing the flexible member 101. The second side surface 1535 is disposed toward the bottom surface 1135. A resisting protrusion 1537 is protruded on the first side surface 1531. A resisting groove 1151 is formed on the side of the connecting portion 115 away from the flexible member 101 for engaging with the resisting protrusion 1537 of the adjacent hinge unit 10.

It can be understood that, in one embodiment, the bottom side of the connecting portion 115 has a resisting groove 1151, and the top side of the resisting block 15 has a resisting protrusion 1537 for matching with the resisting groove 1151.

The connecting portion 115 can move along the guide groove 1131 of the adjacent hinge unit 10. When the end of the connecting portion 115 away from the hinge main body 113 reaches the second position from the first position of the guide groove 1131 of the adjacent hinge unit 10, the connecting portion The resisting groove 1151 of the 115 and the resisting protrusion 1537 of the adjacent hinge unit 10 are clamped and connected, so that the two adjacent hinge units 10 maintain the bending angle, and the connecting portion 115 will not be caused by excessive movement. Damage is caused to the hinge member 11, thereby prolonging the service life of the bendable component 100. In this embodiment, the first position is the end (bottom end) where the guide groove 1131 is adjacent to the bottom surface 1135, and the second position is the end (top end) where the guide groove 1131 is adjacent to the top surface 1133. . It can be understood that the first position may be other positions of the guide groove 1131, and the second position may be other positions of the guide groove 1131. For example, the second position may be the middle position of the guide groove 1131 and so on.

The connecting portion 115 also includes an end surface 1155 away from the hinge body 113. The end surface 1155 includes a convex curved surface. The end surface 1533 includes a concave curved surface that can be matched with the end surface 1155 so as to abut against the end surface 1533 of the adjacent hinge unit 10 at the connecting portion 115, which is beneficial for maintaining the stability of the hinge unit 10 relative to the adjacent hinge unit 10. It can be understood that the end surface 1155 may include a concave curved surface, and the end surface 1533 includes a convex curved surface that can be matched with the end surface 1155.

Further, the receiving cavity 16 includes a first receiving section 161 and a second receiving section 163 connected in sequence. Wherein, compared with the second receiving section 163, the first receiving section 161 is arranged adjacent to the second end surface 1133. The guide groove 1131 is located in the first receiving section 161. The second receiving section 163 forms a resisting step 167 for resisting the sliding portion 151 to prevent the resisting block 15 and the elastic member 14 from leaving the receiving cavity 13.

The bottom surface 1135 is provided with an installation groove 1138 communicating with the receiving cavity 16. The hinge unit 10 further includes a pressing plate 18. The pressing plate 18 is covered by the installation groove 1138 to facilitate the assembly and disassembly of the elastic holding device 13. More specifically, the pressing plate 18 includes a base 181 and a positioning portion 183 protruding from one end of the base 181. The installation slot 1138 includes a bottom wall 1139 and a side wall 1140 connected to the bottom wall 1139. The bottom wall 1139 is provided with a through hole 1143 communicating with the receiving cavity 16 to facilitate the elastic holding device 13 to be inserted into the receiving cavity 16 through the through hole 1143. The side wall 1140 is recessed in the setting slot 1144, and the base body 181 is fixedly received in the mounting slot 1138. The positioning portion 183 is received in the positioning groove 1144 to facilitate the assembly of the pressing plate 18 to the hinge member 11.

The hinge unit 10 further includes a fixing member 19. The pressing plate 18 is fixedly connected to the hinge main body 11 by a fixing member 19, which facilitates the assembly and disassembly of the pressing plate 18.

Please refer to FIG. 11, which is a schematic diagram of a part of the structure of the hinge device. The hinge device 103 includes a first hinge unit 108 (only part of which is shown in FIG. 11), a second hinge unit 109, and a third hinge unit 110 for description. The first hinge unit 108, the second hinge unit 109 and the third hinge unit 110 have the same structure. The connecting shaft 1150 of the connecting portion 115 of the first hinge unit 108 extends from the opening of the receiving cavity 16 of the second hinge unit 109 into a sliding connection with the guide groove 1131 of the second hinge unit 109. The elastic abutment device 13 of the second hinge unit 109 abuts against the connecting portion 115 of the first hinge unit 108. The connecting portion 115 of the second hinge unit 109 extends from the opening of the receiving cavity 16 of the third hinge unit 110 to be slidably connected to the guide groove 1131 of the third hinge unit 110. The elastic abutment device 13 of the third hinge unit 110 abuts against the connecting portion 115 of the second hinge unit 109.

Since the structures of the first hinge unit 108, the second hinge unit 108 and the third hinge unit 110 are the same, the first hinge unit 108 and the second hinge unit 109 are briefly introduced as examples below.

For example, when the connecting shaft 1150 of the first hinge unit 108 is located at the first position of the guide groove 1131 of the adjacent second hinge unit 109 (the guide groove 1131 is away from the bottom end of the flexible member 101), due to the second hinge unit 109 The elastic force of the elastic member 14 toward the opening of the receiving cavity 16 acts to abut the end surface 1155 of the connecting portion 115 of the first hinge unit 108 and the end surface 1533 of the resisting portion 153 of the second hinge unit 109. The parts of the corresponding flexible member 101 on the first hinge unit 108 and the second hinge unit 109 are in a flat state. If the connecting shaft 1150 of each hinge unit 10 is located at the bottom end of the guide groove 1131 of the adjacent hinge unit 10, the entire flexible member 101 is in a flattened state. Please refer to FIG. 12, which is an embodiment of the present invention. A schematic diagram of the bendable component in the flat state, the flexible member 101 is a plane when the bendable component 100 is in the flat state.

When the first hinge unit 108 and the second hinge unit 109 are relatively expanded and the force is less than the first threshold, the end surface 1533 of the resisting block 15 of the second hinge unit 109 is resisted by the force of the elastic member 14 of the second hinge unit 109 The end surface 1155 of the connecting portion 115 of the first hinge unit 108 is held.

When the first hinge unit 108 and the second hinge unit 109 are relatively expanded and the force is greater than or equal to the first threshold, the connecting portion 115 of the first hinge unit 108 overcomes the resistance of the elastic member 14 of the second hinge unit 109 along the second hinge unit The guide groove 1131 of 109 slides, so that the first hinge unit 108 and the second hinge unit 109 are relatively bent. When the first hinge unit 108 is bent relative to the second hinge unit 109, the bending tangential direction of the flexible member 101 changes, that is, it is not fixed.

Please refer to FIGS. 13-14. FIG. 13 is a schematic diagram of a part of the structure when the bendable component is in a bent state, and FIG. 14 is another schematic diagram of a part of the structure of the hinge device when it is bent. When the first hinge unit 108 (only part of which is shown in FIG. 13) is bent relative to the second hinge unit 109, the holding groove 1151 of the connecting portion 115 of the first hinge unit 108 moves toward the guide groove 1131 of the second hinge unit 109 , The resisting block 15 of the second hinge unit 109 is pushed by the connecting portion 115 of the first hinge unit 108 to drive the elastic member 14 of the second hinge unit 109 to deform, and the resisting protrusion 1537 of the second hinge unit 109 is embedded in the first hinge The holding groove 1151 of the unit 108.

For example, the connecting shaft 1150 of the first hinge unit 108 moves from the first position of the guide groove 1131 of the second hinge unit 109 (the guide groove 1131 is away from the bottom end of the flexible member 101) to the second position of the second hinge unit 109 (guide The groove 1131 is adjacent to the top end of the flexible member 101), the resisting protrusion 1537 of the resisting block 15 of the second hinge unit 109 is in engagement with the resisting groove 1151, and is in contact with the elastic member 14 of the second hinge unit 109 Under the action of elasticity, the first hinge unit 108 and the second hinge unit 109 maintain a bending angle. The corresponding parts of the flexible member 101 on the first hinge unit 108 and the second hinge unit 109 are bent, and the flexible member 101 is in a bent state. Please refer to FIG. 15. FIG. 15 shows the bendable component provided in this embodiment in bending Schematic diagram of the state.

When the first hinge unit 108 and the second hinge unit 109 are relatively bent and the force is greater than or equal to the second threshold, the resisting block 15 of the second hinge unit 10 is forced to cause the resisting protrusion 1537 of the second hinge unit 10 to escape The resisting groove 1151 of the first hinge unit 108; and the deformation of the elastic member 14 of the second hinge unit 109 causes the resisting block 15 of the second hinge unit 109 to move toward the elastic member 14 of the second hinge unit 109; the first hinge unit 108 The connecting portion 115 of the second hinge unit 109 slides along the guide groove 1131 of the second hinge unit 109 toward the opening of the receiving cavity 16 until the end surface 1155 of the connecting portion 115 of the first hinge unit 108 and the end surface 1533 of the resisting block 15 of the second hinge unit 109 Resist.

In one embodiment, the hinge device 103 may include two hinge units that are slidably connected. The hinge device 103 includes a first hinge unit 108 and a second hinge unit 109. The first hinge unit 108 includes a connecting portion 115; and the second hinge unit 109 A guide groove 1131 is included; the first hinge unit 108 is slidably connected to the guide groove 1131 of the second hinge unit 109 through a connecting portion 115. That is, the first hinge unit 108 can omit the guide groove 1131 and the elastic abutment device 13. The second hinge unit 109 can omit the connecting portion 115 and the elastic holding device 13.
