Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
To further explain the technical means and effects of the present application for achieving the intended purpose, the following detailed description is given to the present application in conjunction with the accompanying drawings and preferred embodiments.
The embodiment of the application provides a hinge. Referring to fig. 1, a hinge 100 includes a plurality of hinge blocks 10. Each hinge block 10 includes a bottom surface 11 and a top surface 13 opposite to each other in the first direction X, and two abutting surfaces 15 opposite to each other in the second direction Y. The second direction Y is perpendicular to the first direction X. Each abutment surface 15 connects the bottom surface 11 and the top surface 13. Each hinge block 10 is rotatably attached to an adjacent hinge block 10 by an attachment surface 15.
In one embodiment, each of the attachment surfaces 15 includes an extended surface 151 and at least one bent surface 153, the extended surface 151 is connected to the bottom surface 11, the bent surface 153 is connected to the top surface 13, and the bent surface 153 is not coplanar with the extended surface 151. Specifically, the extended surface 151 and the bending surface 153 are both planar, the extended surface 151 is parallel to the first direction X, the bending surface 153 is not parallel to the first direction X and has an included angle α, the bottom surface 11 and the top surface 13 are perpendicular to the first direction X, and the bottom surface 11, the top surface 13, the extended surface 151 and the bending surface 153 are all planar. In other embodiments, the bottom surface 11 and the top surface 13 may also be curved surfaces. The extended surface 151 and the top surface 13 may include a plurality of bending surfaces 153 therebetween, and an included angle between each bending surface 153 and the first direction X gradually increases as approaching the top surface 13.
In one embodiment, the hinge 100 has an unfolded state in which the unfolded surface 151 of each hinge block 10 is attached to the unfolded surface 151 of an adjacent hinge block 10. In the unfolded state, the hinge 100 can be bent only in one direction. Specifically, when the hinge 100 is in the unfolded state, the unfolded surfaces 151 of two adjacent hinge blocks 10 are attached to each other, and at this time, the two hinge blocks 10 can only rotate in one direction, that is, in a direction that can make the bent surfaces 153 of the adjacent hinge blocks 10 approach each other. The bending direction of the hinge 100 can be limited by one or more combinations of the structure of the hinge block 10 (such as the structure in fig. 1), the additional limit structure, the additional hinge chain, and the like.
In one embodiment, the hinge 100 further has a maximum bending state in which the bending surfaces 153 of each adjacent pair of hinge blocks 10 and the top surface 13 are engaged with each other. In the maximum bending state, the hinge 100 can be bent only in one direction. I.e., in a direction that tends to approach between the developed surfaces 151 of the adjacent hinge blocks 10. The maximum bending state of the hinge 100 can also be limited by one or more combinations of the structure of the hinge block 10, the additional arrangement of the limit structure, the additional arrangement of the hinge chain and the like.
In an embodiment, an included angle α between each bending surface 153 of each hinge block 10 and the first direction X can determine an angle of rotation of two adjacent hinge blocks 10 in the bending state compared to the unfolding state, and by setting the included angles α between the bending surfaces 153 of the hinge blocks 10 and the first direction X, an angle of change of the hinge 100 in the maximum bending state compared to the unfolding state can be determined. The angle α can be set by adjusting the distance or area ratio between the bottom surface 11 and the top surface 13, or the size of the area between the unfolded surface 151 and the bending surface 153.
A method for achieving the unfolded state and the maximum bending state will be specifically described, wherein the maximum bending state of the hinge 100 is described in a case that the attachment surface 15 includes only one bending surface 153, and in other embodiments, the above method is also applicable when the attachment surface 15 includes a plurality of bending surfaces 153, and the present application is not limited thereto.
In an embodiment, referring to fig. 2 and fig. 3, a recess 173 is formed on at least one of the attachment surfaces 15 of some of the hinge blocks 10, a protruding structure 171 is disposed on the other attachment surface 15, and each protruding structure 171 is rotatably embedded in the recess 173 of another adjacent hinge block 10. Specifically, when the abutting surfaces 15 of two adjacent hinge blocks 10 abut against each other, the protruding structure 171 on one hinge block 10 is embedded in the recess 173 of the other hinge block 10, and the recess 173 includes a first boundary 173a and a second boundary 173b along the first direction X, so that the protruding structure 171 can move along the first direction X at least partially when embedded in the recess 173.
In an embodiment, referring to fig. 2, when the spreading surfaces 151 of two adjacent hinge blocks 10 are mutually attached, the protruding structure 171 of one hinge block 10 abuts against the first boundary 173a of the recess 173 of the other hinge block 10, and due to the limitation of the protruding structure 171 and the recess 173, the two adjacent hinge blocks 10 can only rotate in one direction (i.e. in a direction in which the bending surfaces 153 of the two adjacent hinge blocks 10 tend to approach), so that the spreading state is achieved.
In an embodiment, referring to fig. 3, when the bending surfaces 153 of two adjacent hinge blocks 10 are engaged with each other, the protruding structure 171 of one hinge block 10 abuts against the second boundary 173b of the recess 173 of the other hinge block 10, and at this time, due to the mutual restriction of the protruding structure 171 and the recess 173, the two adjacent hinge blocks 10 can only rotate in one direction (i.e. in a direction in which the spreading surfaces 151 of two adjacent hinge blocks 10 tend to approach each other), so that the maximum bending state is achieved.
In an embodiment, with continued reference to fig. 2 and fig. 3, in the second direction Y, a distance between the first boundary 173a and the second boundary 173b gradually increases as being away from the attachment surface 15. Specifically, the distance between the first boundary 173a and the second boundary 173b is the same as the thickness of the protruding structure 171 in the first direction X when on the attachment surface 15, thereby fixing the positions of two adjacent hinge blocks 10; when moving away from the attachment surface 15, the distance between the first boundary 173a and the second boundary 173b is greater than the thickness of the protruding structure 171, so that a portion of the protruding structure 171 can move between the first boundary 173a and the second boundary 173 b.

The binding plate 33 is further provided with a limiting through hole 330, and the fixing column 31 passes through the limiting through hole 330 and can relatively move in the limiting through hole 330 along the second direction Y. That is, the fixing column 31 and the binding plate 33 form the limiting structure 30, and the fixing column is disposed in the limiting through hole 330 on the binding plate 33, so that the relative position between the fixing column 31 and the binding plate 33 can be limited, thereby limiting the relative position between the top surfaces 13 of two adjacent hinge blocks 10, and further limiting the rotation degree between two adjacent hinge blocks 10. In other embodiments, the limiting structures 30 can also be arranged on the bottom surfaces 11 of two adjacent hinge blocks 10, or on both the bottom surfaces 11 and the top surfaces 13 of two adjacent hinge blocks 10.
In an embodiment, referring to fig. 4 and 5, when the unfolding surfaces 151 of two adjacent hinge blocks 10 are attached to each other, the fixing post 31 is located at one end of the limiting through hole 330, so that the fixing post 31 can only move in the second direction Y toward the direction close to the adjacent hinge block 10, and thus the two adjacent hinge blocks 10 can only rotate in one direction, that is, the unfolding state of the hinge 100 is achieved.
In an embodiment, referring to fig. 6 and 7, when the bending surfaces 153 of two adjacent hinge blocks 10 are attached to each other, the fixing post 31 is located at one end of the limiting through hole 330, so that the fixing post 31 can only move in the second direction Y in a direction away from the adjacent hinge blocks 10, and thus the two adjacent hinge blocks 10 can only move in one direction, that is, the maximum bending state of the hinge 100 is realized.
In an embodiment, the binding plate 33 may be made by hinging two rigid plates (not shown) with each other, so that when two adjacent hinge blocks 10 rotate relatively, the two rigid plates on the binding plate 33 also rotate relatively, and when two adjacent hinge blocks 10 are in the maximum bending state, the two rigid plates on the binding plate 33 respectively abut against the top surfaces 13 of the two hinge blocks 10, so as to cooperate with the fixing column 31 to perform the limiting function. In other embodiments, the two rigid plates on the binding plate 33 may also be rotatably joined by a flexible material or other means, so as to perform a limiting function, which is not limited in the present application.

In one embodiment, when the unfolded surfaces 151 of two adjacent hinge blocks 10 are attached to each other, the two adjacent hinge blocks 10 can be bent only in one direction under the restriction of the hinge chain 50, thereby realizing the unfolded state of the hinge 100; similarly, when the bending surfaces 153 of two adjacent hinge blocks 10 are engaged with each other (not shown), the two adjacent hinge blocks 10 can be bent only in one direction under the restriction of the hinge chain 50, thereby achieving the maximum bending state.
In one embodiment, the hinge strip 50 is also used to fix the relative position between two adjacent hinge blocks 10, and the plurality of hinge strips 50 cooperate to facilitate the reinforcement of the hinge 100.

Since the two abutting surfaces 15 of each hinge block 10 are respectively located at two ends of the hinge block 10 along the second direction Y, the two abutting surfaces 15 of each hinge block 10 respectively have the first magnetism N and the second magnetism S, so that the abutting surfaces 15 of two adjacent hinge blocks 10 with different magnetism are rotatably abutted under the action of magnetic force. In other embodiments, both ends of one part of the hinge blocks 10 in the second direction Y have the first magnetism N, both ends of the other part of the hinge blocks 10 in the second direction Y have the second magnetism S, and the hinge blocks 10 with the first magnetism N and the hinge blocks 10 with the second magnetism S can attract each other under the action of the magnetic force.
