1 to 7 are views of a portable terminal according to an embodiment of the present invention, Figures 1, 2 and 5 are a perspective view, part of the display of the portable terminal according to an embodiment of the present invention in a closed state A longitudinal cross-sectional view and a partially enlarged longitudinal cross-sectional view are respectively shown, and FIGS. 3, 4 and 6 are a perspective view, a partial longitudinal cross-sectional view and a partially enlarged longitudinal cross-sectional view, respectively, when the display of the portable terminal according to an embodiment of the present invention is opened. 7 is a longitudinal cross-sectional view showing the configuration and operation of the angle adjustment unit.

As shown in the drawing, the portable terminal according to an embodiment of the present invention is configured to be rotatably coupled to the display hinge part 300 so that the display 200 is opened and closed at a predetermined angle to the terminal body 100. do. An embodiment to be described below will be described based on a portable terminal of a folder-type, but is not limited thereto. Bar-type, slide-type, and swivel-type It can be applied to various types of portable terminals.

The terminal body 100 is composed of a terminal case, the terminal case is composed of a main case 110 and a cover case 120 coupled to the main case 110 to be opened and closed.
The main case 110 has a battery 140 is coupled to the rear portion, and is provided with an antenna 150 for transmitting and receiving a wireless signal on the upper side.

An accommodating groove 121 is formed in the cover case 120, and the display 200 is coupled to the accommodating groove 121 by the display hinge part 300.

The display hinge unit 300 is rotatably coupled to a shaft groove (not shown) formed in the front portion of the receiving groove 121 of the cover case 120 is a horizontal pivot 310 provided on the lower end of the display 200 An elastic member (not shown) that is elastically supported to open the display 200 is coupled to the horizontal pivot shaft 310.

The horizontal pivot shaft 310 of the display 200 is integrally formed at the lower end of the display 200 as shown in FIGS. 1 and 4 or formed separately from the display 200 as shown in FIG. 8. Can be.

And the cover case 120 is coupled to the operation unit 400 is configured to lock the display 200 in a closed position, the angle adjustment unit 500 is coupled to use to adjust the opening angle of the display 200. Consists of.

The operation unit 400 is the operation button 410 is coupled to the button hole 123 formed in the cover case 120 as well as the lock rod 420 on the guide 124 formed on the lower portion of the cover case 120 Is inserted, the inclined surface 412 for moving the lock rod 420 by pushing the front portion of the operating hole 421 formed in the middle of the lock rod 420 to the lower end of the operating rod 411 of the operation button 410 Is formed, the inner side of the guide portion 124 by pushing the lock rod 420, the locking rod elastic for elastically supporting the rear end engaging portion 422 to be caught in the locking groove 311 of the horizontal pivot shaft 310 The member 430 is comprised.

An operation button elastic member 413 that elastically supports the operation button 410 upward may be coupled to the operation rod 411 of the operation button 410.

The angle adjustment unit 500 is a screw rod 510 is coupled to the guide 125 formed between the receiving groove 121 and the button hole 123 of the cover case 120, the middle of the screw rod 510 The upper side of the adjusting wheel 530 to be sub-screw is projected to the outside of the display 200 through the wheel hole 126 formed in the cover case 120, the screw rod 510 is moved back and forth by the adjusting wheel 530 At the rear end of the), a stopper 520 for limiting the opening of the display 200 is coupled.

The stopper 520 is preferably formed of an elastic material so that the display 200 is in smooth contact.

Referring to the operation of the portable terminal according to an embodiment of the present invention as described above is as follows.

1, 2 and 5 illustrate a state in which the cover case 120 is closed in the main case 110 of the portable terminal according to the present invention, and includes a locking groove 311 formed in the horizontal pivot shaft 310 of the display 200. The rear end locking portion 422 of the lock rod 420 is inserted into the lock rod 420, and the lock rod elastic member 430 such as the compression spring is elastically pushed to lock the lock rod 420, thereby horizontally rotating the display 200. Even if the elasticity of the spring such as the torsion spring acts on the coaxial 310, the display 200 cannot be opened and the closed state is stably maintained.

1, 2 and 5 in the state of pressing the operation button 410 protruding to the front portion of the cover case 120, the operating rod 411 of the operation button 410 is moved to the lower operating rod 411 ), The inclined surface 412 of the lock rod 420 pushes the front of the operation hole 421 of the lock rod 420, so that the lock rod 420 moves forward, and the rear end locking portion 422 of the lock rod 420 is The locking groove 311 is formed in the horizontal pivot shaft 310, and thus the display 200 is inclined at a predetermined angle as shown in FIGS. 3, 4, and 6 by restoring elasticity of the elastic member.

And the mobile terminal according to an embodiment of the present invention, when the adjustment wheel 530 of the angle adjustment unit 500 installed in the cover case 120, as shown in Figure 7, the screw rod 510 is moved back and forth, As a result, the position of the stopper 520 fixed to the rear end of the screw rod 510 is adjusted before and after. When the stopper 520 moves backward, the opening angle of the display 200 decreases and moves forward. In this case, since the opening angle of the display 200 is increased, the opening angle of the display 200 may be adjusted according to the user's taste before opening the display 200, and then the screen may be opened at a comfortable angle.

As such, when the display 200 is inclinedly opened, the user may more clearly see various information and images such as the time displayed on the display 200.

In addition, when the display 200 is to be closed in the open state as shown in FIGS. 3, 4 and 6, when the display 200 is lightly pushed down, the horizontal pivot shaft 310 rotates clockwise with the display 200. When the display 200 is completely closed, the rear end locking portion 422 of the locking rod 420 is positioned on the same line as the locking groove 311 of the horizontal pivot shaft 310, and the locking rod is locked to the locking rod 420. Restoration elasticity of the elastic member 430 acts so that the rear end locking portion 422 of the lock rod 420 is inserted back into the locking groove 311 of the horizontal pivot shaft 310 to have a relation with FIGS. 1, 2 and 5. The closed state remains stable.

8 is a perspective view illustrating a modified example of the mobile terminal according to the present invention, and as shown in the cover case 120, a horizontal pivot shaft 310 formed separately from the display 200 is rotatably coupled thereto. In addition, the display 200 is configured to be coupled to the horizontal pivot shaft 310 so as to be rotatable from side to side via a vertical pivot shaft 320, and as illustrated, the display 200 is configured to rotate the horizontal pivot shaft 310. In the open state by) can be rotated left and right by the vertical rotation shaft 320, the user can see from a more comfortable angle by adjusting the angle of the display 200 as necessary. In the modified example of the display inclination opening device, other configurations and operations are the same as in the above-described embodiment.

In the portable terminal according to the present invention as described above, when the operation button provided in the terminal case is pressed, the display is erected at an angle that the user can comfortably view, and the opening angle of the display can be adjusted using the control wheel. Depending on your needs, you can open the display at the right angle to view the screen clearly and comfortably, which is very easy to use if you need to keep watching the LCD such as music videos, movies, and MP3s. It works.
