Description
Technical Field
The present invention relates to a display device, and more particularly, to a display device having a ball-type biaxial hinge structure attached to a folder, which allows a portable display device such as a smart phone (smart phone) or a tablet to be folded or unfolded.
Background
Unless otherwise indicated herein, what is described in this section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section.
In general, a portable folding device (referred to as a mobile device) such as a communication terminal, a multimedia device, and a portable computer includes a display unit for displaying image information and a main body unit connected to the display unit so as to be foldable with respect to each other and including an input unit such as a keyboard. The mobile device has a folding configuration that can be folded in a smaller size so as to have portability.
Although not shown in the drawings, the main body portion having the keyboard portion and the display portion displaying the image information can be folded relatively by forming a drive gear at an arbitrary position on the multi-axis hinge shaft, and by forming a plurality of driven gears in the same specification as the drive gear and cooperating with the drive gear in a mutually fitting (meshing) manner.
In this case, since the drive gear and the driven gear formed in the same specification are formed of at least 4 gears, the number of parts increases, and thus, not only does the manufacturing cost and the assembly cost increase, but also a space and a predetermined thickness for installing the hinge structure formed in the 4-gear type in the main body portion and the folded portion of the display portion are required, and thus, the tendency of the electronic device to be thin, light, and compact cannot be satisfied, and thus there is a problem that the competitiveness of the electronic device is reduced.
On the other hand, in the case of the hinge device of the portable terminal, since the hinge portion in which the display portion is folded with respect to the main body portion is formed in a cam type, the folding of the display device is not gentle and failures frequently occur, so that there is a problem that the reliability of the electronic apparatus is lowered.

in the swing structure 16 described above, when the main body 10 or the display unit 11 is folded relatively within an arbitrary angle range, one of the first and second drive shafts 13 and 15 rotating in the forward or reverse direction is pressed, and thereby the other of the first and second drive shafts 13 and 15 is simultaneously rotated in the reverse direction by the plurality of first and second swing balls 19 and 20 arranged such that the first and second swing grooves 17 and 18 along the curved line (in the form of an "S", as an example) move on the same plane.
As shown in fig. 1 and 2, a display device having a ball-type biaxial hinge structure according to a more preferred embodiment is characterized in that the swing structure 16 described above includes:
a swing member 24 including a connection block 21, and a left swing coupler 22 and a right swing coupler 23 of a left-right symmetrical type, wherein the connection block 21 is disposed at the center thereof and prevents the first and second swing balls 19 and 20 from being separated from the first and second swing grooves 17 and 18, and the left swing coupler 22 and the right swing coupler 23 of the left-right symmetrical type are disposed to be in close contact with the left and right sides of the connection block 21 and are rotatable in a forward direction or a reverse direction;
a first body 25 closely attached to an upper surface of the swing member 24 and having a first swing groove 17 formed on a bottom surface thereof so that the first swing ball 19 is seated and moved; and the number of the first and second groups,
and a second body 26 closely attached to the bottom surface of the swing member 24 and having a second swing groove 18 formed at an upper surface thereof symmetrically to the first swing groove 17 so that the second swing ball 20 is seated and moved.
As shown in fig. 2 and 3(b), the display device having the spherical biaxial hinge structure according to the present embodiment includes:
an upper connecting pin 27 and a lower connecting pin 28 formed to protrude from any position of the upper and lower surfaces of the connecting block 21; and the number of the first and second groups,

the first and second bodies 25 and 26 are integrally fixed to the upper and lower portions of the swing member 24 by the upper and lower connection pins 27 and 28 being fitted into the first and second support holes 29 and 30.
As shown in fig. 2, 5(a), 5(b), 6(a) and 6(b), the display device having the ball-type biaxial hinge structure according to the present embodiment is characterized in that the first and second swing grooves 17 and 18 described above include:
a first seating groove 31 of a straight line shape formed in a length direction at a middle side of the first and second bodies 25, 26 for seating the first and second swing balls 19, 20; and the number of the first and second groups,
and second circumferential seating grooves 34 formed on the inner circumferential edges of the first and second fitting holes 32 and 33 on the left and right sides of the first and second bodies 25 and 26 so as to extend to the left and right sides of the first seating groove 31, for seating the first and second rocking balls 19 and 20.
As shown in fig. 2 and 3(a), the display device having the biaxial ball hinge structure according to the present embodiment includes swing protrusions 35 formed to protrude from the upper and lower surfaces of the left and right swing couplings 22 and 23 so as to be circularly movable along the second seating grooves 34 when the first driving shaft 13 or the second driving shaft 15 is rotated,
thus, when the main body 10 or the display portion 11 is folded relatively within an arbitrary angle range, the first swing ball 19 or the second swing ball 20 is pressed by the swing protrusion 35 that performs a circular motion in the second seating groove 34, and the first swing ball 19 or the second swing ball 20 moves along the first swing groove 17 or the second swing groove 18, thereby transmitting a rotational force to one of the left and right swing couplings 22 and 23 to rotate the same.
As shown in fig. 2, 3(a) and 3(b), the display device having the biaxial ball hinge structure according to the present embodiment is characterized in that the left and right contact surfaces of the connecting block 21 are formed as curved surfaces so as to contact the outer peripheral edges of the left and right swing couplers 22 and 23 described above and smoothly perform a circular motion.
Hereinafter, a display device including a ball-type biaxial hinge structure according to an embodiment of the present specification will be described with reference to the drawings.
As shown in fig. 5(a) and 6(a), the display device including the body 10 and the display portion 11 that are hinged to each other so as to be foldable relative to each other by the first and second hinges 12 and 14 and the first and second drive shafts 13 and 15 is generally used in the technical field to which the present specification is applied, that is, an electronic device such as a portable smartphone and a tablet computer, and thus detailed description of the configuration and the use method thereof will be omitted.
As shown in fig. 5a and 7, when the display device described above is folded in the forward direction (clockwise direction) (i.e., in a folding mode in which the main body 10 and the display unit 11 are folded from 180 degrees to 90 degrees or 0 degrees, which is unfolded), the main body 10 to which the first hinge 12 is attached is rotated in the forward direction (clockwise direction) about the first driving shaft 13. At this time, the display unit 11 to which the second hinge 14 is attached rotates in the reverse direction (counterclockwise direction) about the second drive shaft 15.
The details thereof are as follows: when the first driving shaft 13 is rotated by the folding operation of the body 10 as described above, the left rocking coupling 22 engaged with the first driving shaft 13 is rotated in the circumferential direction by only an arbitrary angle, and the rocking protrusion 35 formed on the upper surface of the left rocking coupling 22 is rotated, whereby the plurality of first rocking balls 19 seated in the first rocking groove 17 of the first main body 25 are pressurized to perform a curved motion in the S-shaped state.
As shown in fig. 5(b), the swing protrusion 35 of the left swing coupling 22, which rotates in the forward direction (clockwise direction) by the rotation of the first drive shaft 13, rotates to press one end of the first swing ball 19 positioned in the second seating groove 34 of the left swing coupling 22, whereby the first swing ball 19 moves in a zigzag curve along the first swing groove 17 in the direction from the right side to the left side in the figure.
At the same time, as shown in fig. 5(c), the second swing ball 20 placed in the second swing groove 18 in the S-shape is pressed to make the second swing ball 20 perform a curved motion along the second swing groove 18 in a direction from the left side to the right side in the drawing, wherein the second swing groove 18 is formed on the upper surface of the second body 26 closely attached to the bottom surface of the swing member 24 as described above symmetrically to the first swing groove 17 of the first body 25.
As described above, when the first driving shaft 13 attached to the body 10 rotates, the first rocking ball 19 moves in a zigzag manner (moves in a direction from the right side to the left side) along the first rocking groove 17 of the first body 25 by the rotation of the rocking protrusion 35 of the left rocking joint 22 (see fig. 5a and 5 b), and at the same time, when the second driving shaft 15 attached to the display portion 11 rotates, the second rocking ball 20 moves in a zigzag manner (moves in a direction from the left side to the right side) along the second rocking groove 18 of the second body 26 by the rotation of the rocking protrusion 35 of the right rocking joint 23 in a direction opposite to that of the first rocking ball 19 (see fig. 5a and 5 c).
Accordingly, when the first driving shaft 13 described above rotates, the second driving shaft 15 is simultaneously rotated in the direction opposite to the first driving shaft 13 by the first and second rocking balls 19 and 20 which perform a curved motion in the S-shape along the first and second rocking grooves 17 and 18, and the display device including the main body 10 and the display portion 11 can be folded in the normal direction.
As shown in fig. 6 a and 7, when the display device described above is folded in the reverse direction (counterclockwise direction) (i.e., in an unfolding mode in which the main body 10 and the display unit 11 are unfolded from 0 degrees to 90 degrees or 180 degrees of the folded state), the main body 10 to which the first hinge 12 is attached rotates in the reverse direction (counterclockwise direction) about the first driving shaft 13. At this time, the display unit 11 to which the second hinge 14 is attached rotates in the forward direction (clockwise direction) about the second drive shaft 15.
The details thereof are as follows: as shown in fig. 6 a and 6 b, when the second driving shaft 15 is rotated in the forward direction (clockwise direction), the right rocking coupling 23 engaged with the second driving shaft 15 is also rotated in the forward direction, and the rocking protrusion 35 formed on the upper surface of the right rocking coupling 23 is rotated, whereby the plurality of first rocking balls 19 seated in the first rocking groove 17 and the second seating groove 34 of the first body 25 are pressurized to perform a curved motion in the S-shaped state.
That is, the swing protrusion 35 of the right swing coupling 23, which rotates in the normal direction by the rotation of the second drive shaft 15, rotates to pressurize one end of the first swing ball 19 positioned in the second seating groove 34 of the right swing coupling 23, whereby the first swing ball 19 moves in a curved line in the S-shape in the direction from the left side to the right side in the drawing.
Meanwhile, as shown in fig. 6(a) and 6(c), the second rocking ball 20 seated in the second seating groove 34 of the right rocking coupling 23 and the second rocking groove 18 in the S-shaped state is pressurized to make the second rocking ball 20 perform a curved motion in a direction from the right side to the left side in the drawing, wherein the second rocking groove 18 is formed on the upper surface of the second body 26 closely attached to the bottom surface of the rocking member 24 symmetrically to the first rocking groove 17 of the first body 25.
As described above, when the second driving shaft 15 mounted to the display part 11 is rotated in the forward direction, the first swing ball 19 is moved in a curved manner in an S-shaped manner along the first swing groove 17 and the second seating groove 34 of the first body 25 by the rotation of the right swing coupling 23, and at the same time, when the first driving shaft 13 mounted to the body 10 is rotated in the reverse direction, the second swing ball 20 is moved in a curved manner in an S-shaped manner along the second swing groove 18 and the second seating groove 34 of the second body 26 by the rotation of the left swing coupling 22 in a direction opposite to the first swing ball 19.
Accordingly, when the second driving shaft 15 rotates, the first and second rocking balls 19 and 20 which curve in the S-shape along the first and second rocking grooves 17 and 18 simultaneously rotate the first driving shaft 13 in the direction opposite to the second driving shaft 15 in conjunction with each other, and the display device including the main body 10 and the display portion 11 can be folded in the reverse direction.
Although the present specification described above has been described with reference to the preferred embodiments, those skilled in the art will appreciate that various modifications and changes can be made to the present specification without departing from the spirit and scope of the present specification as set forth in the appended claims.
