In the terminal illustrated in FIG. 15, a rear end of the display panel 110 is hinged to the portable terminal main body 100 in a rotatable manner.

In order to protect the LCD as in the case of the notebook PC, this terminal can normally be closed with the LCD side of the display panel 110 facing inward, and the hinge structure (hinge) containing a friction mechanism using a spring only when used is used. It can be opened at an appropriate angle by using the structure, and the angle opened by the friction load of the friction mechanism is maintained. However, this method has a limit in the opening angle of the display panel 110.

The terminal illustrated in FIG. 16 allows the display panel 110 to be adjusted to an angle using a support hinge 120 having a biaxial hinge on the portable terminal main body 100.

The terminal shown in FIG. 17 is known from Japanese Laid-Open Patent Publication No. 2002-23650 (P2002-23650A), and the display panel 110 has a support-type hinge 130 having a biaxial hinge on the portable terminal body 100. Use it to adjust the angle, so that only the monitor can be pulled up in that state, it is intended for ease of use in narrow airplane, rail travel.

However, despite such many development efforts, there are still many limitations in using the display device and many inconveniences in using the display device require continuous research and development.

The present invention was devised to solve the above-mentioned problems and defects, and the angle of the screen display device can be adjusted in a range of approximately 360 degrees by using a hinge so that it can be used in a general portable display device or in an automobile. It is an object of the present invention to provide a display panel angle adjusting device of a terminal that can be fixed to enjoy a movie or various multimedia.

In order to achieve the above object, the display panel angle adjusting device of the terminal according to the present invention is coupled to a rotational angle adjusting part which enables the rear end of the display panel to be angle-adjustable and the inversion of the display window to the rear end of the terminal body, The rotation angle adjusting unit is rotatably coupled to the first hinge portion and the second hinge portion via an elastic positioning element and an elastic clamping element, respectively, at both ends of the rear portion of the portable terminal body and at both ends of the display panel. An inter-rotational rotating element is provided to rotate the operating lever provided in the front portion of the front to mechanically transfer the rotational force to rotate the inter-rotation.

In addition, the guide hole is formed in the lower side of the fixed hole between the rotation, the stop pin is fixed to both ends of the terminal body is inserted so that the rotation between the rotation of the guide hole by a predetermined angle, for example 90 degrees.

The rotating element between the rotational element is coupled to one side or both sides of the terminal body so as to be movable in the longitudinal direction back and forth, the operation lever is rotatably coupled to the front end of the terminal body, the pinion provided on the operation lever It is configured to engage the rack gear formed at the distal end of the electric lever, and rotate the interlock as the rack gear formed at the rear end of the electric lever engages the pinion provided in the interlock.

In general, a terminal such as a portable AV device or a notebook PC has a display panel designed to interoperate with the terminal body for displaying information. For example, the main body is capable of inserting and reproducing media such as a disc.

The display panel is connected by a hinge having a plurality of hinges, in the present invention, the two-axis hinge hinge plays a role. The reason why the two-axis hinge is used instead of the single-axis hinge is that at least two degrees of freedom are required in order to rotate the display panel around the terminal body having a predetermined thickness. The biaxial hinge hinge has two hinge parts, a first hinge part connected to the terminal body side and a second hinge part connected to the display panel.

In this case, the first hinge part is rotatably coupled via the elastic positioning element, and the second hinge part is rotatably coupled via the elastic clamping element, so that a rotation of the first hinge part requires a predetermined limit or more to rotate. The display panel unit can be stopped at an angle.

In addition, since the frictional load of the first hinge part is set to be much greater than the frictional load of the second hinge part, when the display panel is turned while holding the display panel, the second hinge part rotates first before the first hinge part returns. As a result, by properly locking or releasing these two hinges, the angle of the display panel can be adjusted to a predetermined angle and posture.

As a result, the present invention can be rotated by 90 degrees with respect to the first hinge portion of the biaxial hinge hinge in this configuration example, the display panel can be rotated again 180 degrees relative to the second hinge portion.

This invention embodies a mechanism for limiting the locking and unlocking of the first and second hinges while eliminating the addition of unnecessary parts other than the hinges. Also, it can be used upside down by 180 degrees depending on the application. In addition, when the LCD is flipped, the display direction of the screen can be selected by the user, and when the LCD is opened at a desired angle, the angle is maintained.

And the present invention provides the convenience of using the LCD in a narrow space, such as cars, airplanes, trains.

As described above, the display panel angle adjusting device of the terminal according to an embodiment of the present invention holds the display panel 20 closed on the terminal body 10 as shown in FIGS. 1, 2, and 3. As shown in FIG. 5, the angle may be arbitrarily adjusted by rotating the center shaft pin 32, and the display window 21 of the display panel 20 may be closed in an inverted form as illustrated in FIGS. 1 to 5.

Figure 5 shows the configuration and basic concept of the present invention, the display panel 20 is designed so that the terminal, such as a portable AV device or a notebook PC (PC) in general, interlocked with the terminal body 10 for information display Has

For example, the main body is capable of inserting and reproducing media such as a disc.

The display panel 20 is connected by a hinge having a plurality of hinges. In the present invention, the biaxial hinge hinge plays a role. The reason why the biaxial hinge is used instead of the short axis hinge is that at least two degrees of freedom are required in order to rotate the display panel 20 around the terminal body 10 having a predetermined thickness. The biaxial hinge hinge has two hinge parts, a first hinge part 30a connected to the terminal body 10 side and a second hinge part 30b connected to the display panel 20.

Here, the first hinge portion 30a is rotatably coupled via the resilient positioning element 41, and the second hinge portion 30b is rotatably coupled via the elastic clamping element 42. It is required to apply a force above a certain limit to return, and it is possible to stop the display panel 20 at a predetermined angle.

In addition, since the friction load of the first hinge part 30a is set to be much greater than the friction load of the second hinge part 30b, the first hinge part 30a returns when the display panel 20 is turned while holding the display panel 20. Before the second hinge portion 30b is turned first. As a result, by properly locking or releasing these two hinges, the angle of the display panel 20 can be adjusted to a predetermined angle and posture.

In addition, in the state of FIG. 4A, when the operation lever 52 provided in the front portion of the terminal body 10 rotates downward, the pinion 53 of the operation lever 52 rotates. The electric lever 51 engaged with the rack gear 51a moves forward, and the rotational lever 31 engaged with the pinion 54 with the rack gear 51b of the electric lever 51 rotates to rotate. The liver 31 is rotated so that the display panel 20 can be moved to the rear of the terminal body 10 as shown in FIG. 4B.

6A and 6B, guide holes 31b are formed at the lower end of the pivot 31, and stop pins 14 fixed to both ends of the terminal body 10 are inserted into the guide holes 31b. Therefore, the rotation section 31 rotates only in the range where the guide hole 31b is caught by the stop pin 14, and the protrusion 31c of the rotation section 31 is formed on the first hinge portion 30a of the rotation section 31. And a plurality of projections 31d and grooves 35a are formed on the annular finger plate 35 and are provided with a click type elastic positioning element 41 which is compressed by the compression spring 36. 31) can be rotated at a predetermined angle, for example, in the range of 90 degrees, and the rotational period 31 can be held at an arbitrary angle by the projections 31d and the recesses 35a of the click-type elastic positioning element 41. Will be.

8A and 8B are enlarged longitudinal cross-sectional views of the stop button part, and the outer surface of the stop button 15 in the form of a push button is caught by the second hinge part 30b to restrict the rotation of the rotation section 31. When the stop button 15 is pressed by the user, the rotation section 31 is released from the restriction and rotates. Before pressing the stop button 15, the display panel 20 can only turn based on the second hinge portion 30b.

After the stop button 15 is pressed and the rotation 31 is rotated by 90 degrees and fixed again by the click type resilient positioning element 41, the stop button 15 is restored to its original position by the spring 16. The outer surface of the stop button 15 is caught by the second hinge portion 30b again, and the rotation of the rotation period 31 is again regulated, and thus the display panel 20 is based on the second hinge portion 30b. Will turn.

Accordingly, the display panel 20 can be flipped up to 180 degrees as shown in FIGS. 3, 4 and 5, and the display panel 21 of the LCD unit faces outward as shown in FIG. 4. As a result, when the pivot 31 of the biaxial hinge hinge rotates by 90 degrees with respect to the first hinge portion 30a in this configuration example, the display panel 20 is again based on the second hinge portion 30b. It will turn 180 degrees.

When closing, the original position of the display panel 20 is possible by the reverse operation.

FIG. 10 shows a state in which the display panel 21 of the display panel 20 is viewed from the front by opening the display panel 20 at a predetermined angle with respect to the portable terminal body 10.

FIG. 11 shows a state in which the display window 21 of the display panel 20 is viewed from the rear by turning the display panel 20 back to the portable terminal body 10 and opening the display panel 20 at a predetermined angle.

FIG. 12 illustrates a state in which the display window 21 of the display panel 20 is adjusted upward by closing the display panel 20 in the state of FIG. 11.

FIG. 13 illustrates a state in which the display window 21 of the display panel 20 is inserted into a cradle 50 fixed to a dashboard of a vehicle in a state in which the display window 21 of the display panel 20 is adjusted upward.

As described above, in the display panel angle adjusting device of the terminal according to the present invention, since the rotation axis of the first hinge is present in the product direction, the desired purpose can be achieved when the two-axis hinge hinge rotates only 90 degrees. Since the operating position of the hinge is located on a line almost equal to the main body, there is a good advantage to induce a compact design of the main body.

As described above, the present invention not only opens and adjusts and fixes the display panel at a predetermined angle, but also has an advantage of being turned upside down on the opposite side of the main body by being rotated 180 degrees in some cases.

Furthermore, the present invention rotates the operation lever provided in the front part of the terminal body, and transmits this rotational force to the electric lever provided at both ends and the pinion, and rotates the rotation between the pinion to rotate the rotation angle between the display panel and the terminal. There is an advantage that can be adjusted by simple operation of the control lever in the front of the body.

If the angle is adjusted so that the LCD is in contact with the main body while facing outward, it is convenient to use the stylus on the LCD surface like a tablet PC or to digitize it. .

In addition, the portable DVD can be easily utilized in limited space when using a train or an airplane.

In addition, when used for car navigation, it is easily utilized by inserting the display and the body in a 180 degree tilted state on the cradle attached to the car.

Therefore, the present invention is not limited to the use environment and use, as the conventional display is limited to the angle control as in the prior art, the use environment and use is not limited to the angle by using the hinge of the angle of the display device By being adjustable in a range of almost 360 degrees, it is effective to use the screen display device anytime and anywhere, regardless of the use and place.
