Referring to the driving process of the buried display device 100 according to an embodiment of the present invention having the above structure as follows.

4 to 5 show a state in which the image device is withdrawn from the housing,

4 is a schematic diagram showing a state in which the image device is accommodated in the accommodating part of the housing, and FIG. 5 is a schematic diagram illustrating a state in which the image device is drawn out from the accommodating part of the housing.

6 is a schematic diagram showing a state in which the image device is rotated by an external force.

4 to 6, in a state where the image device 120 is accommodated in the accommodating part 111, the first motor 141 to the third motor 161 are operated to operate the first rotating member 150. The second rotating member 160 and the image device fixing bracket 170 are rotated. The imaging device 120 is drawn out from the accommodating part 111 and comes to the position of A shown in FIG.

Next, the process of rotating the image device 120 rotated to the original position by the external force is as follows.

When the image device 120 is forcibly rotated by an external force, the image device 120 rotates from the A position to the B position. At the same time, the rotation angle transmission gear 183 (see FIG. 2) also rotates by the rotation angle R, and the rotation angle detector gear 182 (see FIG. 2) engaged with the rotation angle transmission gear 183 (see FIG. 2) also rotates. Accordingly, the rotation angle detection sensor 181 (see FIG. 2) generates angle data rotated by the rotation angle detector 182 (see FIG. 2). Such angle data is transmitted to a controller (not shown). When the user presses a button for receiving an image device, which is not shown, the controller calculates the transmitted angle data and operates the third motor 161 to move the image device 120 to the original A position. When the third motor 161 operates, the third drive gear 162 is rotated, and the third fixed gear 171 engaged thereto rotates to rotate the image device 120 to rotate to the A position. 3 The motion of the motor 161 is stopped.

In the buried display device 100 according to the exemplary embodiment of the present invention as described above, a process in which the image device 120 is stored and drawn out on the wall surface 101 is automatically performed. Accordingly, the user can directly manipulate the hinge assembly 130 by hand, thereby eliminating the inconvenience of allowing the image device 120 to be stored in the accommodation portion 111.

In addition, when the image display apparatus 120 is rotated by an external force, the embedded display apparatus 100 measures the angle at which the image apparatus 120 is rotated so that the image apparatus 120 is rotated to its original position. Accordingly, in the process of accommodating the image device 120 in the accommodating part 111, the image device 120 and the accommodating part 111 may be accommodated in an equilibrium state with each other.

Meanwhile, the hinge assembly 130 may further include a slip generator 200.

The slip generator 200 prevents the third motor 161 or the third drive gear 162 from being damaged by the rotation of the third fixed gear 171 by rotating the image device 120 by an external force. It plays a role.

7 is an exploded perspective view showing a slip generating part, FIG. 8 is a perspective view showing a slip generating part, and FIG. 9 is a sectional view showing a slip generating part.

7 to 9, the slip generator 200 includes a first slip member 210, a second slip member 220, and an elastic member 230.

The first slip member 210 includes a first contact portion 211, a first inclined portion 212, and a first clearance 213.

The first contact portion 211 is fixed to the image device fixing bracket 170 and rotates with the rotation of the image device 120, and is a cylindrical member disposed in the vertical direction.

The first inclined portion 212 extends downward from the lower end of the first contact portion 211 to increase an inner diameter.

The first clearance 213 extends in a cylindrical shape from a lower end of the first inclined portion 212. The first clearance 213 is integrally formed with the rotation angle transmission gear 183.

The second slip member 220 includes a second contact portion 221, a second inclined portion 222, and a second clearance 223.

The second contact portion 221 extends from the upper side of the third fixed gear 171 and is a cylindrical member whose circumference is disposed in the vertical direction.

The second inclined portion 222 extends from the upper end of the second contact portion 221 so that the outer diameter thereof becomes smaller.

The second clearance 223 extends in a cylindrical shape from an upper end of the second inclined portion 222.

The elastic member 230 is formed between the first slip member 210 and the second slip member 220, and the upper side is pressed and fixed outwardly to the inner diameter of the first contact portion 211, the lower side is the second contact portion 221 Inward direction is fixed to the outer diameter of). The elastic member 230 is preferably made of a coil spring. Since both ends of the coil spring are fixed to the first and second contact portions, when a difference in rotation angle occurs between both ends, the coil diameter increases or decreases due to torsion.

Referring to the operation of the slip generating unit 200 having the above structure as follows.

When the user strikes the image device 120, the image device 120 is rotated by an external force. After the rotation of the image device 120, the rotation angle transmission gear 183 is rotated, the diameter of the elastic member 230 becomes smaller or larger. When the diameter increases, the upper side of the elastic member 230 is more strongly in contact with the inner diameter of the first contact portion 211, the lower side of the elastic member 230 is in loose contact with the outer diameter of the second contact portion 221. Accordingly, slip is generated between the first slip member 210 and the second slip member 220 so that the rotational force of the rotation angle transmission gear 183 is not transmitted to the third motor 161 without the rotation angle transmission gear. The rotational force of 183 is transmitted to the third motor 161 in a reduced state.

Meanwhile, the slip generator 200 is formed in the first and second fixed gears 151 and 161 so that the first motor 141 and the second motor 151 are formed by the first and second fixed gears 151 and 161. It is also possible to prevent) from being broken.

In another embodiment, the operation portion may be a simple key button.

According to another aspect of the present invention, the display apparatus includes at least one rotation angle detector for detecting a state of the hinge assembly. The rotation angle detector is a variable resistor in the illustrated embodiment. Since the hinge rotation range is very limited, it is possible to detect the degree of rotation sufficiently by using the variable resistance knob that moves only in the limited range. The signal converter applies a constant current to the variable resistor and converts the output voltage signal into a digital value through an analog-digital converter.

In another embodiment, the rotation angle detector is a magnetic or optical encoder. In this case, the signal converter counts the pulse train output from the encoder and outputs a digital information value of the rotation degree.

The controller determines how much more each motor needs to be driven in order to adjust the viewing angle indicated by the user with reference to the current hinge state detected by the rotation angle detector. In another function, the control unit manually adjusts the angle of the display to an appropriate viewing angle, and when a user presses a specific button, for example, a posture memory button, the control unit detects a state of the current hinge assembly in the rotation angle detector and stores it in the memory. Save and set as audiovisual information. Accordingly, the user can more conveniently set an audiovisual angle suitable for the user. Of course, the viewing angle adjustment may also be set by pressing the posture memory button after setting the viewing angle by manipulating the viewing angle adjusting button of the remote controller, for example, a driving key commonly referred to as Navi-Key.
