The embodiments disclosed below are provided as examples to enable those skilled in the art to fully convey the concept of the present invention. The present invention is not limited to the embodiments described below, but may be embodied in other forms. In order to clearly explain the present invention, portions not related to the explanation are omitted in the drawings, and widths, lengths, thicknesses, and the like of the components in the drawings may be expressed in an enlarged manner for convenience. Like reference numerals refer to like elements throughout the specification.
Fig. 1 is a diagram schematically showing a hinge device 2 and an electronic apparatus 1 having the same according to an embodiment.
The electronic device 1 may include a tablet computer, a notebook computer, a PDA, a mobile phone, a smart phone, and other portable electronic devices, and the hinge device 2 may be adapted to a plurality of the electronic devices 1 through appropriate modification.
As shown in fig. 1 and 2, an electronic apparatus 1 according to an embodiment includes a hinge device 2, a pair of bodies 3 disposed along both sides of the hinge device 2, and a flexible display 4.
Although not shown, the body 3 may include a circuit module for controlling the operation of the electronic device 1, a power supply module, a rechargeable battery, etc., and the body 3 may be combined with an additional frame.
In the figure, unexplained reference numeral 5 denotes a cover member that covers the hinge device 2 and the body 3 in the process of connecting the hinge device 2 to the body 3.
The cover members 5 may form a pair, and each cover member 5 may be connected in a state where the flexible display 4 surrounds the one side body 3 and a half of the hinge device 2 in the back surface direction.
The pair of bodies 3 are connected to each other so as to be foldable and rotatable between 0 and 180 degrees by the hinge device 2 disposed therebetween.
The pair of bodies 3 rotating in the 0-degree folding state can be folded with each other, and the pair of bodies 3 is changed from the state rotating in the 180-degree folding state to the state of being spread out flatly.
Both sides of the back surface of the flexible display 4 are supported by the surfaces of the pair of bodies 3, and the hinge device 2 may be positioned to correspond to the back surface of the center portion of the flexible display 4.
The flexible display 4 can be folded such that the folding portion 4a forms an oval shape.
Referring to fig. 1 to 3, the hinge device 2 may include: a central hinge housing 6; a pair of rotating members 7 disposed along both sides of the hinge housing 6; and a hinge module 8 for rotatably connecting with the hinge housing 6.
The pair of bodies 3 of the electronic apparatus 1 are rotatably coupled to the outer sides of the pair of rotating members 7, respectively, and in this state, can be folded and rotated between 0 degrees and 180 degrees by the hinge device 2. The outer side of the rotating member 7 may be rotatably connected with the body 3 by a rotating shaft 3 a.
The hinge housing 6 may include a groove 6a opened in a rear direction of the flexible display 4 in order to assemble the hinge module 8.
The hinge modules 8 may be formed in a pair to be assembled in a symmetrical manner with each other at both end portions along the length direction of the hinge housing 6. A central bracket 9 for supporting a pair of hinge modules 8 may be provided at the center of the hinge housing 6.
As shown in fig. 4 and 5, the hinge module 8 includes a pair of connection members 10 that rotatably connect the pair of rotation members 7 to the hinge housing 6.
The connecting member 10 includes a slide member 20, and the rotating member 7 is rotatably connected to an outer side of the slide member 20, and an inner side is connected to the hinge housing 6 in such a manner as to slide along an arc-shaped trajectory in a side direction.
The sliding member 20 can slide in an outward direction to enlarge the interval between the hinge housing 6 and the rotating member 7 in the process of being folded between the pair of bodies 3 of the electronic apparatus 1 so as to form 0 degree, whereby a length change caused by the folding work of the flexible display 4 can be compensated.
The sliding member 20 that slides in an arc-shaped state is slidable in an outward direction in a process of being folded at 0 degrees between the pair of bodies 3 of the electronic apparatus 1 and is folded outward between the rotating members 7 that are rotatably connected. Therefore, the separation between the slide member 20 and the rotation member 7 to the outside of the folded portion 4a of the flexible display 4 formed in the elliptical shape can be facilitated, whereby the folded portion 4a can be more effectively prevented from being damaged by the hinge device 2.
In this state, as the posture of the electronic apparatus 1 is switched so that the pair of main bodies 3 form 180 degrees again, the slide member 20 slides toward the inside of the hinge housing 6 to make the surface of the rotation member 7 horizontal with the surface of the main body 3, and in this case, the rotation member 7 stably supports the back surface of the flat flexible display 4 together with the main body 3.
The hinge module 8 may include a guide member 30 fixed to the hinge housing 6 for guiding the sliding operation of the sliding member 20.
The sliding member 20 may include an arc-shaped sliding coupling portion 21 slidably coupled with the guide member 30, and the guide member 30 includes an arc-shaped sliding groove 31 in which the sliding coupling portion 21 is slidably coupled in a withdrawable manner, so that the sliding operation of the sliding coupling portion 21 sliding in an arc-shaped trajectory may be stably guided.
The slide groove 31 is opened to the side of the hinge housing 6 to guide the sliding operation of the slide coupling portion 21 sliding inward or outward.
The slide member 20 may include a rotation coupling portion 22 extending in an outward direction from the slide coupling portion 21 so as to be coupled to the rotation member 7.
The rotation coupling portion 22 is in the form of a flat plate extending in a straight line from the end of the slide coupling portion 21 so that the surface thereof can be horizontal to the surface of the rotating member 7 in a state where the slide coupling portion 21 is slid to the inside of the slide groove 31 to the maximum extent so as to spread 180 degrees between the main bodies 3 of the electronic apparatus 1.
The pair of guide members 30 are supported by each other along the longitudinal direction of the hinge housing 6, and are fixed to the grooves 6a of the hinge housing 6 by bolts 6b so that the opening directions of the slide grooves 31 are opposite to each other. The slot 6a may form a boss 6c for fastening the bolt 6 b.
The pair of slide members 20 are rotatably connected to the rotation members 7 on both sides by rotation shafts 7a fastened to rotation holes 22a, respectively, the rotation holes 22a being provided in the outer rotation coupling portions 22, and are rotatably connected to the rotation members 7 in a state slidable in the lateral direction in the guide members 30 as the inner slide coupling portions 21 are slidably inserted into the slide grooves 31 of the pair of guide members 30, respectively.
The hinge module 8 may include an interlocking member 40 for interlocking the rotation of the pair of rotation members 7, and the interlocking member 40 may include an interlocking gear 50 provided at one end portion in the longitudinal direction of the hinge housing 6.
The linkage gear 50 may include: a pair of first interlocking gears 51 provided on the outer side so as to rotate together with the cover members 5 on both sides; a pair of second interlocking gears 52 provided inside so as to rotate via the pair of first interlocking gears 51; and support members 53 and 54 for supporting shafts 51a and 52a of the first and second interlocking gears 51 and 52.
The support member 54 may be fixed to one end side of the hinge housing 6, and the support member 53 may support a portion of the pair of guide members 30 adjacent to one end portion of the hinge housing 6. The support members 53, 54 may be coupled to each other by providing the interlocking gear 50.
Therefore, when one of the pair of rotating members 7 rotates together with the one side cover member 5, the pair of rotating members 7 may be interlocked and rotated in a state of forming a symmetrical structure with each other as the other of the pair of rotating members rotates together with the opposite side cover member 5 receiving the rotational force through the interlocking gear 50.
Also, the hinge module 8 may include an elastic unit 60 elastically supporting the sliding member 20 in an outward sliding direction when the rotating member 7 rotates.
The elastic unit 60 elastically supports the sliding member 20 in an outside direction when the rotating member 7 rotating together with the body 3 rotates, whereby it is possible to secure an operation performance of the sliding member 20 that a separation space 8a for protecting the folded portion 4a is secured outside the folded portion 4a during the rotation of the body 3 of the electronic apparatus 1 in the folding direction.
The elastic unit 60 may include: an elastic member 61; a pressing member 62 for applying an elastic pressure to the slide member 20 via the elastic member 61; and a cam 63 provided between the pressing member 62 and the sliding member 20 so as to maintain the sliding of the sliding member 20 by the pressing force of the pressing member 62.
The guide member 30 may include an opening groove 32 that opens the slide groove 31 along the longitudinal direction of the hinge housing 6, and the pressing member 62 and the guide member 30 may be disposed adjacent to each other along the longitudinal direction of the hinge housing 6 such that the opening groove 32 of the guide member 30 faces the end of the pressing member 62.
Also, the cam 63 may include: a first cam portion 70 provided in the slide coupling portion 21 so as to extend toward the pressing member 62 through the open groove 32; and a second cam portion 80 provided at an end portion of the pressing member 62 so as to slide the first cam portion 70.
In the arrangement structure of the pressing member 62 and the guide members 30, the entire structure of the hinge module 8 is closely arranged along the longitudinal direction of the hinge housing 6 together with the structure in which the pair of guide members 30 are closely attached to each other along the longitudinal direction of the hinge housing, and therefore, the width of the hinge housing 6 can be suppressed from being excessively increased by the action of the slide member 20.
The pair of guide members 30 may be formed to support each other by forming a point-symmetrical structure such that the directions of the slide groove 31 and the open groove 32 are opposite to each other.
The pressing member 62 is attached to a support member 64 so as to be slidable in the longitudinal direction of the hinge housing 6, and the support member 64 is fixed to the hinge housing 6 by a bolt 6 b.
The pressing member 62 may include a pair of sliding shafts 62a and a connecting portion 62b at one end, the connecting portion 62b being for connecting between the pair of sliding shafts 62 a.
The elastic member 61 may include a pair of wire springs 61a that are caught around a pair of sliding shafts 62 a. One end of the wire spring 61a can support the connecting portion 62b, and the other end is supported by the support member 64.
The support member 64 may include: a coupling hole 64a for coupling of the sliding shaft 62 a; and a support portion 64b for supporting a central portion of the connection portion 62 b.
For reference, unexplained reference numeral 65 denotes a support washer coupled to the slide shaft 62a in such a manner as to support the wire spring 61 a.
The second cam portion 80 may protrude so as to form an annular sector (annular sector) formed along the sliding track of the sliding coupling portion 21 on the surface of the connecting portion 62 b.
The second cam portion 80 may form a cam surface 81 along the protruding direction side. The cam surface 81 may include: a pair of inclined surfaces 81a provided on both end portions of the second cam portion 80; and a flat surface 81b provided between the pair of inclined surfaces 81 a.
A stopper 90 may be further protrudingly formed on a surface of the connecting portion 62b along one side of the second cam portion 80 to limit the sliding movement of the first cam portion 70 with respect to the second cam portion 80.
The first cam portion 70 may have a triangular-shaped protrusion structure. The first cam portion 70 can protrude toward the pressing member 62 side so as to be drawn out from the slide coupling portion 21 to the outside of the open groove 32 of the guide member 30 and can be in contact with the second cam portion 80.
The folding and rotating operation of the hinge device 2 and the electronic apparatus 1 having the same configured as above will be described below.
As shown in fig. 6, in a state where the electronic apparatus 1 is unfolded so as to form 180 degrees between the pair of bodies 3, the hinge device 2 makes the surface of the rotating member 7 horizontal with the surface of the body 3, thereby stably supporting the back surface of the flexible display 4 in a flat state together with the body 3.
In this case, in the slide member 20, the slide coupling portion 21 slides to the inside of the slide groove 31 to the maximum extent, and the surface of the rotation coupling portion 22 of the slide member 20 may be formed to be horizontal to the surface of the rotation member 7.
In this state, as shown in fig. 7, when the main body 3 is rotated at an acute angle so as to fold the main body 3, the slide coupling portion 21 of the slide member 20 starts to be drawn outward of the slide groove 31 and slightly slides outward.
In this case, the first cam portion 70 applies pressure to the pressing member 62 so as to compress the elastic member 61 and is guided to the inclined surface 81a side of the other end through the inclined surface 81a and the flat surface 81b of the one end of the second cam portion 80, as shown in fig. 8, and in this state, the first cam portion 70 is pushed to the inclined surface 81a of the second cam portion 80 by the restoring action of the elastic member 61 and receives pressure to the side, and the slide member 20 can be slid to the maximum slide position.
Accordingly, the pair of main bodies 3 of the electronic apparatus 1 is folded and rotated in the folded state, and in this case, the space between the slide member 20 and the rotating member 7 which slide in the outward direction is folded in the outward direction and separated to the outside of the folded portion 4a of the flexible display 4 which forms the oval shape, whereby the folded portion 4a can be prevented from being damaged by the hinge device 2.
A support groove 5a may be formed at an inner face of the cover member 5 to support a connection portion between the sliding member 20 folded to the outside and the rotating member 7 in a placed state.
