[0020] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0021] The following combination Figures 1 to 14 The connecting device described in the embodiments of this application will be described in detail.

[0022] The connecting device described in this application includes: at least two connecting bodies; the at least two connecting bodies are used to support the flexible member 200; a first connecting body 110 of adjacent connecting bodies among the at least two connecting bodies is provided with a first connecting portion 130, and a second connecting body 120 of adjacent connecting bodies among the at least two connecting bodies is provided with a second connecting portion 140, the first connecting portion 130 and the second connecting portion 140 are rotatably connected; the first connecting body 110 is rotatable relative to the second connecting body 120 based on the rotatable connection of the first connecting portion 130 and the second connecting portion 140; the at least two connecting bodies are rotatable to a first limit position and a second limit position based on the rotation of the first connecting body 110 relative to the second connecting body 120.

[0023] In the embodiments of this application, the specific states of the at least two connecting bodies in the first and second extreme positions are not limited. For example, Figure 6 As shown, when the at least two connecting bodies are in the first extreme position, the at least two connecting bodies are in a bent state, such as... Figure 7 As shown, when the at least two connecting bodies are in the second extreme position, the at least two connecting bodies are in a straightened state.

[0024] Of course, when the at least two connecting bodies are in the first extreme position and the second extreme position, the at least two connecting bodies can be in a bent state.

[0025] It should be noted that the side connector of at least two connectors may be only the first connector 110 or the second connector 120, that is, the side connector may only include the first connecting portion 130 or the second connecting portion 140; the middle connector of at least two connectors may be the first connector 110 and the second connector 120, that is, the middle connector of at least two connectors may include the first connecting portion 130 and the second connecting portion 140; so that at least two connectors can rotate based on the rotation of the first connector 110 relative to the second connector 120.

[0026] As an example, a second connecting portion 140 is further provided on the second side of the first connecting body 110; wherein, the second side of the first connecting body 110 is disposed opposite to the first side of the first connecting body 110, and the first connecting portion 130 on the first side of the first connecting body 110 and the second connecting portion 140 on the second side of the first connecting body 110 are staggered. Figure 13 and Figure 14 As shown. Here, the first connector 110 is located in the middle of at least two connectors.

[0027] In the embodiments of this application, the number of at least two connectors is not limited. As an example, such as Figure 1 and Figure 2 As shown, the number of at least two connectors is five.

[0028] The shape of the connector is not limited here. For example, the connector can be a cuboid structure or a columnar structure.

[0029] Here, the structure of the connector is not limited. For example, the connector may also include shielding protrusions 150 located at both ends of the connector to ensure a uniform appearance. Here, "both ends" refers to the two ends along the length of the connector. The structure of the shielding protrusions 150 is not limited. For example, as... Figure 13 and Figure 14 As shown, the occlusion protrusion 150 can be fan-shaped.

[0030] In this embodiment, the structure of the flexible member 200 is not limited. For example, the flexible member 200 can be a leather part. As another example, the flexible member 200 can also be a flexible screen.

[0031] Here, the method by which the connector supports the flexible member 200 is not limited. For example, the connector can support the flexible member 200 through protrusions. Or, for example, the connector can support the flexible member 200 through its surface.

[0032] Example 1: When the at least two connectors are in the first extreme position, the at least two connectors support the flexible member 200 in a bent state, and the flexible member 200 is in contact with the two supporting ends of the connectors, such as... Figure 6 As shown; when the at least two connectors are in the second extreme position, the at least two connectors support the flexible member 200 in an unfolded mode, and the flexible member 200 contacts the supporting surface of the connector, making the flexible member 200 flat and wrinkle-free, as shown. Figure 7 As shown, supporting the flexible member 200 with the support surface can prevent the flexible member 200 from collapsing in the support area of ​​the connector.

[0033] In Example 1, the cross-sectional shape of the connector can be either triangular or trapezoidal. Here, the two supporting ends of the connector can be pointed, such as... Figure 6 As shown. Of course, the two supporting ends of the connector can also be smooth ends, such as... Figure 4 As shown, the two supporting ends of the connector include curved surfaces to prevent the connector from damaging the flexible component 200.

[0034] In Example 1, the two support ends refer to the support ends in the width direction of the connecting body.

[0035] In this embodiment, the structure of the first connecting portion 130 and the second connecting portion 140 is not limited, as long as the first connecting portion 130 and the second connecting portion 140 are rotatably connected. For example, the first connecting portion 130 may include a connecting hole, and the second connecting portion 140 may include a connecting convex shaft, which is sleeved in the connecting hole and can rotate relative to the connecting hole.

[0036] Here, the number of first connecting portions 130 and the number of second connecting portions 140 are not limited. For example, as Figure 1 As shown, the first connector 110 includes at least two first connectors 130, and the second connector 120 includes at least two second connectors 140, so that the first connector 110 and the second connector 120 are connected by a plurality of first connectors 130 and second connectors 140.

[0037] Here, the first connecting part 130 and the first connecting body 110 can be an integral structure or a separate structure.

[0038] Here, the second connecting part 140 and the second connecting body 120 can be an integral structure or a separate structure.

[0039] As an example, such as Figure 8 and Figure 9As shown, the connecting device may further include: a first receiving groove 111 and a second receiving groove 121. The first receiving groove 111 is disposed on a first side of the first connecting body 110; a first portion of the first connecting part 130 is fixed in the first receiving groove 111; the second receiving groove 121 is disposed on a first side of the second connecting body 120, and the second receiving groove 121 corresponds to the position of the first receiving groove 111; a first portion of the second connecting part 140 is fixed in the second receiving groove 121; a portion of the first connecting part 130 is located in the second receiving groove 121, and the volume of the portion of the first connecting part 130 located in the second receiving groove 121 changes with the relative rotation of the first connecting body 110 and the second connecting body 120; a portion of the second connecting part 140 is located in the first receiving groove 111, and the volume of the portion of the second connecting part 140 located in the first receiving groove 111 changes with the relative rotation of the first connecting body 110 and the second connecting body 120.

[0040] Here, the first connecting part 130 and the first connecting body 110 are configured as separate structures, and the second connecting part 140 and the second connecting body 120 are configured as separate structures for processing and manufacturing.

[0041] Here, the shapes of the first receiving groove 111 and the second receiving groove 121 are not limited. For example, the cross-sectional shape of the first receiving groove 111 and the cross-sectional shape of the second receiving groove 121 are both fan-shaped.

[0042] In some optional implementations of this application's embodiments, the connector may include a large end and a small end, the large end of which is used to support the flexible member 200; when the at least two connectors are in the first extreme position, such as Figure 6 As shown, the small ends of the adjacent connectors have a first distance L1, and the large ends of the adjacent connectors have a second distance L2; when the at least two connectors are in the second extreme position, as... Figure 7 As shown, there is a third distance L3 between the small ends of the adjacent connectors and a fourth distance L4 between the large ends of the adjacent connectors; so that the connectors can support the flexible member 200 through the large end with a larger area.

[0043] In this implementation, the cross-sectional shape of the connector is not limited. For example, the cross-sectional shape of the connector can be triangular, trapezoidal, or sector-shaped. As an example, ... Figure 6 and Figure 7 As shown, the cross-sectional shape of the connecting body is similar to a trapezoid.

[0044] In this implementation, the value of the third distance L3 is greater than the value of the first distance L1, and the value of the fourth distance L4 is greater than the value of the second distance L2; that is, when the at least two connectors are in the first extreme position, the distance between adjacent connectors among the at least two connectors is the smallest, and when the at least two connectors are in the second extreme position, the distance between adjacent connectors among the at least two connectors is the largest.

[0045] In this implementation, during the rotation of the first connector 110 relative to the second connector 120 in a first direction, when the distance between the small end of the first connector 110 and the small end of the second connector 120 is at its minimum, and the distance between the large end of the first connector 110 and the large end of the second connector 120 is at its minimum, the at least two connectors are in the first extreme position. As the first connector 110 gradually rotates relative to the second connector 120, the distance between the small end of the first connector 110 and the small end of the second connector 120 gradually increases, and the distance between the large end of the first connector 110 and the large end of the second connector 120 gradually increases. The at least two connectors gradually rotate from the first extreme position to the second extreme position. When the first connector 110 rotates relative to the second connector 120 to the point where the distance between the small end of the first connector 110 and the small end of the second connector 120 is at its maximum, and the distance between the large end of the first connector 110 and the large end of the second connector 120 is at its maximum, the at least two connectors are in the second extreme position.

[0046] In Example 1, during the rotation of the first connector 110 relative to the second connector 120 in the second direction, when the distance between the small end of the first connector 110 and the small end of the second connector 120 is at its maximum, and when the distance between the large end of the first connector 110 and the large end of the second connector 120 is at its maximum, the at least two connectors are in the second extreme position. As the first connector 110 gradually rotates relative to the second connector 120, the distance between the small end of the first connector 110 and the small end of the second connector 120 gradually decreases, and the distance between the large end of the first connector 110 and the large end of the second connector 120 gradually decreases. The at least two connectors gradually rotate from the second extreme position to the first extreme position. When the first connector 110 rotates relative to the second connector 120 to the point where the distance between the small end of the first connector 110 and the small end of the second connector 120 is at its minimum, and the distance between the large end of the first connector 110 and the large end of the second connector 120 is at its minimum, the at least two connectors are in the first extreme position; wherein, the first direction and the second direction are opposite.

[0047] In Example 1, when the at least two connecting bodies are in the first extreme position, the values ​​of the first distance L1 and the second distance L2 can be equal.

[0048] In Example 1, the value of the third distance L3 is much greater than the value of the first distance L1, and the value of the fourth distance L4 is only slightly different from the value of the second distance L2. During the rotation of the at least two connecting bodies, the distance between the small end of the first connecting body 110 and the small end of the second connecting body 120 changes significantly. That is, it can be clearly seen that the small end of the first connecting body 110 and the small end of the second connecting body 120 gradually move closer or further apart, while the distance between the large end of the first connecting body 110 and the large end of the second connecting body 120 does not change significantly.

[0049] In some optional implementations of the embodiments of this application, such as Figure 3 As shown, the first connector 110 is rotatably connected to the first connector 130 and the second connector 140 and is rotatable relative to the second connector 120 about a first rotation center D. The first rotation center D is located on the side of the first connector 110 and the second connector 120 that supports the flexible member 200, and the first rotation center D is located outside the first connector 110 and the second connector 120.

[0050] In this implementation, the method of rotatably connecting the first connecting part 130 and the second connecting part 140 so that the first rotation center D is located outside the first connecting body 110 and the second connecting body 120 is not limited.

[0051] For example, the first connecting portion 130 may include a first curved surface; the second connecting portion 140 may include a second curved surface; the second curved surface contacts a first portion of the first curved surface, and the second curved surface is capable of rotating relative to the first curved surface about a first rotation center; the first connecting body 110 and the second connecting body 120 are capable of rotating relative to each other based on the rotation of the first curved surface relative to the second curved surface; here, the position of the first rotation center is not fixed.

[0052] For example, the first connecting portion 130 may include a first arc surface; the second connecting portion 140 may include a second arc surface; the second arc surface contacts the first arc surface, and the second arc surface is rotatable relative to the first arc surface about a first rotation center D; the first connecting body 110 and the second connecting body 120 are rotatable relative to each other based on the rotation of the first arc surface relative to the second arc surface; here, the first arc surface and the second arc surface are concentric, and the center of the first arc surface and the center of the second arc surface are both located outside the first connecting body 110 and the second connecting body 120; here, the position of the first rotation center D is fixed.

[0053] Here, the curvature of the first arc surface and the curvature of the second arc surface can be equal, and the first rotation center D can be located within the plane of symmetry of the adjacent connecting bodies among the at least two connecting bodies. Of course, the first rotation center D may also not be located within the plane of symmetry of the adjacent connecting bodies among the at least two connecting bodies.

[0054] In this implementation, when the at least two connectors are in the first extreme position, the connectors support the flexible member 200 at a first length B1, such as... Figure 5 As shown; when the at least two connectors are in the second extreme position, the connectors support the flexible member 200 at a second length B, as... Figure 4 As shown.

[0055] Here, when the at least two connectors are in the first extreme position, and the at least two connectors are used to support the flexible member 200 in a bent state, the first length B1 is the arc length. The formula for calculating the first length B1 is: B1 = A × π × R1 / 180; where A is the central angle corresponding to the connector, π is pi, and R1 is the radius corresponding to the flexible member 200.

[0056] It is important to note that, such as Figure 5As shown, when the cross-sectional shape of the connecting body is symmetrical and the at least two connecting bodies are in the first extreme position, the center C is the intersection of the symmetry lines E of the cross-section of each connecting body; here, the symmetry lines E of the cross-sections of all connecting bodies intersect at the center C.

[0057] The central angle A is the angle formed by the two first rotation centers D corresponding to the connector and the center C. R1 is the distance between the neutral surface of the flexible part 200 and the center C, that is, R1=L5+H / 2; L5 is the distance between the supporting end of the connector and the center C, and H is the thickness of the flexible part 200.

[0058] Here, as Figure 4 As shown, when the at least two connectors are in the second extreme position, and the at least two connectors are used to support the flexible member 200 in an unfolded state, the second length B can be the chord length. The formula for calculating the second length B is: B = 2R × SIN(A / 2); where A is the central angle corresponding to the connector, and R is the radius of rotation corresponding to the connector.

[0059] Central angle A is the angle formed by the two first rotation centers D and the center C of the circle corresponding to the connecting body. R is the distance between the first rotation center D and the center C.

[0060] Here, the first length B1 and the second length B can be equal, so that the flexible part 200 is in a flat state, i.e. without wrinkles, when it is in the first extreme position and the second extreme position. At this time, B1=B, A×π×R1 / 180=2R×SIN(A / 2), so that the correspondence between R and R1 can be calculated. Those skilled in the art can set the size of angle A according to actual needs and design the structure of the connector based on the correspondence between R and R1.

[0061] It should be noted that the above calculations of the structure of the connector are merely examples, and those skilled in the art can make adjustments according to actual needs.

[0062] In this implementation, the first length B1 and the second length B may not be equal.

[0063] In some optional implementations of the embodiments of this application, the first connecting portion 130 may include a first arc surface; the second connecting portion 140 may include a second arc surface. The second arc surface contacts the first arc surface, and the second arc surface is rotatable relative to the first arc surface about a first rotation center; the first connecting body 110 and the second connecting body 120 are rotatable relative to each other based on the rotation of the first arc surface relative to the second arc surface.

[0064] In this implementation, the first rotation center can be located outside the first connector 110 and the second connector 120, or it can be located inside the first connector 110 or the second connector 120.

[0065] In this implementation, under the influence of external force, the first connecting body 110 rotates relative to the second connecting body 120 based on the rotation of the first arc surface relative to the second arc surface; when the external force is removed, the first connecting body 110 maintains its positional relationship with the second connecting body 120 based on the frictional force between the first arc surface and the second arc surface. That is, the frictional force between the first arc surface and the second arc surface enables the at least two connecting bodies to be in a stable state, thereby enabling the at least two connecting bodies to be stably located at any position between the first limit position and the second limit position.

[0066] Of course, those skilled in the art can also maintain the positional relationship between the first connector 110 and the second connector 120 in other ways.

[0067] In this implementation, the structure of the first and second arc surfaces is not limited.

[0068] For example, such as Figure 8 and Figure 9 As shown, the first connecting portion 130 may include: an annular groove 131; the side of the groove 131 forms a first arc surface 133, here, the groove 131 forms two first arc surfaces 133; the second connecting portion 140 may include: an annular protrusion structure 141; the protrusion structure 141 is inserted into the groove 131, and the protrusion structure 141 is rotatable relative to the groove 131 about the first rotation center; the side of the protrusion structure 141 forms a second arc surface 143, here, the protrusion structure 141 forms two second arc surfaces 143.

[0069] Of course, the first connecting portion 130 may also include only a first arc surface 133. For example, the first connecting portion 130 may be a groove 131 with a fan-shaped cross-section. The second connecting portion 140 may also include only a second arc surface 143. For example, the second connecting portion 140 may be a protruding structure 141 with a fan-shaped cross-section.

[0070] In this example, such as Figure 9 As shown, the connecting device may further include: a limiting groove 132 and a limiting protrusion 142. The limiting groove 132 is disposed on the inner wall of the sliding groove 131, as shown. Figure 12 As shown; the limiting protrusion 142 is disposed on the protruding structure 141, as... Figure 11As shown, the limiting protrusion 142 corresponds to the limiting groove 132.
