Abstract

The present invention relates to a display device. According to the present invention, the display device comprises: a display body from which an image is outputted; and a flip hinge assembly which is coupled with the display body, wherein the flip hinge assembly comprises: a fixing unit that is fixed to the display body; a rotation unit that is coupled with the fixing unit to allow rotation thereon; a first elastic member that is coupled with the rotation unit and the fixing unit; and a second elastic member that has one end coupled with the fixing unit, and has the other end selectively contacted with the rotation unit, wherein said second elastic member provides, to the rotation unit, an elastic force which is opposite to an elastic force provided to the rotation unit by the first elastic member. Thus, according to the present invention, an initial tilting angle of the display body is automatically set, thereby increasing user convenience.

Claims

1. A display device comprising:

a display main body from which an image is output; and

a flip hinge assembly coupled to the display main body,

wherein the flip hinge assembly comprises;

a stationary part fixed to the display main body;

a rotary part rotatably coupled to the stationary part;

a first elastic member coupled to the rotary part and the stationary part; and

a second elastic member, an end of which is coupled to the stationary part, and the other end thereof selectively contacts the rotary part,

wherein the second elastic member applies elastic force to the rotary part in a direction opposite to a direction of elastic force the first elastic member applies to the rotary part.

2. The display device according to claim 1, wherein the rotary part comprises:

a hinge shaft functioning as a rotation shaft when the display main body is tilted; and

a flip hinge body rotating with the hinge shaft.

3. The display device according to claim 2, wherein the stationary part comprises:

a coupling bracket coupled to a rear surface of the display main body, and supporting a side portion of the hinge shaft; and

a supporting bracket coupled to the coupling bracket, and supporting another side portion of the hinge shaft.

4. The display device according to claim 3, wherein an end of the first elastic member is coupled to the supporting bracket, and the other end thereof is coupled to the hinge shaft.

5. The display device according to claim 2, wherein the hinge shaft comprises a non-circular part having a non-circular cross section,

the flip hinge body has an insertion hole in which the hinge shaft is inserted, and

the insertion hole has a shape corresponding to the non-circular part.

6. The display device according to claim 2, further comprising a pressing member that is coupled to the hinge shaft and selectively contacts the second elastic member.

7. The display device according to claim 6, wherein the second elastic member is bent such that the first end thereof is coupled to the coupling bracket, and the second end thereof selectively contacts the pressing member.

8. The display device according to claim 2, wherein when an angle formed between the flip hinge body and the display main body is within a preset angle range, the second elastic member contacts the rotary part.

9. The display device according to claim 2, wherein a coupling nut for coupling the flip hinge body to the hinge shaft is coupled to an end of the hinge shaft, and

a fastening member is coupled to the coupling nut to fasten the coupling nut.

10. The display device according to claim 9, wherein a fastening male screw part is disposed on an outer portion of the coupling nut, and

a female screw part that is screwed to the fastening male screw part is disposed on an inner portion of the fastening member.

11. The display device according to claim 1, wherein the first elastic member and the second elastic member are torsion springs.

12. A display device comprising:

a display main body from which an image is output;

a hinge shaft coupled to a rear surface of the display main body;

a flip hinge body coupled to the hinge shaft and rotating with the hinge shaft;

a first elastic member, an end of which is coupled to the display main body, and the other end thereof is coupled to the hinge shaft to pull the hinge shaft in a direction;

a second elastic member having an end coupled to the display main body, wherein when an angle formed between the flip hinge body and the display main body is within a preset angle range, the other end of the second elastic member applies elastic force to the hinge shaft or the flip hinge body to rotate the hinge shaft in another direction.

13. The display device according to claim 12, wherein the first elastic member and the second elastic member are torsion springs.

14. The display device according to claim 12, further comprising a pressing member that is coupled to the hinge shaft and selectively contacts the second elastic member.

15. The display device according to claim 14, wherein the pressing member protrudes a predetermined length from an outer circumferential surface of the hinge shaft.

16. The display device according to claim 14, wherein an end part of the second elastic member is bent at a predetermined angle to form a catching part,

wherein when the flip hinge body is rotated through a predetermined angle or greater by the first elastic member, the catching part contacts the pressing member.

17. The display device according to claim 12, wherein a stand having a space accommodating the hinge shaft and the flip hinge body is coupled to the rear surface of the display main body.

18. The display device according to claim 17, wherein a coupling nut for coupling the flip hinge body to the hinge shaft is coupled to an end of the hinge shaft, and

a fastening member is coupled to the coupling nut to fasten the coupling nut.

19. The display device according to claim 17, wherein the fastening member is inserted into the stand from an outside of the stand and is connected to the coupling nut.

20. The display device according to claim 17, wherein the stand comprises a first body and a second body, which are coupled to each other, and

the flip hinge body is disposed between the first and second bodies.
