Abstract

Disclosed are a control box and a display device including the same. The control box includes a case providing an inner accommodation space and having an opening formed in the upper surface thereof, a first plate supported by the lower surface of the case, a second plate located on the first plate so as to be spaced apart from the first plate, a third plate located on the second plate so as to be spaced apart from the second plate, a rotary plate covering the opening in the case and rotatably mounted to the third plate, and a transceiver located inside the case and coupled to the rotary plate. The display device includes a head including a display panel, and the head exchanges information with the transceiver.

First claim

What is claimed is:

1. A control box comprising:
a case providing an inner accommodation space, the case having an opening formed in an upper surface thereof;
a rotary plate covering the opening, the rotary plate being rotatably disposed to the opening of the case; and
a transceiver located inside the case, the transceiver being pivotably coupled to the rotary plate.

2. The control box according to claim 1 , wherein the control box further comprises:
a first plate supported by a lower surface of the case;
a second plate located on the first plate, the second plate being spaced apart from the first plate; and
a third plate located on the second plate, the third plate being spaced apart from the second plate.

3. The control box according to claim 1 , wherein the transceiver comprises:
a heat sink; and
at least one antenna mounted to the heat sink.

4. The control box according to claim 3 , wherein the heat sink comprises:
a front part on which the at least one antenna is mounted;
a rear part facing the front part, the rear part being spaced apart from the front part;
a top part connecting an upper side of the front part and an upper side of the rear part; and
a bottom part connecting a lower side of the front part and a lower side of the rear part.

5. The control box according to claim 4 , wherein the heat sink comprises:
at least one fin located between the top part and the bottom part, the at least one fin extending to connect the front part and the rear part.

6. The control box according to claim 5 , wherein a thickness of the at least one fin is smaller than at least one of a thickness of the front part, a thickness of the rear part, a thickness of the top part, or a thickness of the bottom part.

7. The control box according to claim 6 , wherein the transceiver further comprises:
a cooling fan coupled to one side of the heat sink.

8. The control box according to claim 2 , further comprising:
a fan coupled to an upper side of the third plate; and
a shock absorber located between the fan and the third plate.

9. The control box according to claim 8 , wherein the fan comprises:
an inlet formed in a surface thereof facing the shock absorber;
a housing providing a flow passage for air introduced thereinto through the inlet; and
an outlet formed in one side of the housing.

10. The control box according to claim 9 , wherein the shock absorber includes a flow passage communicating with the inlet of the fan.

11. The control box according to claim 10 , wherein the third plate includes an opening communicating with the flow passage in the shock absorber.

12. The control box according to claim 9 , further comprising:
a discharge guide located on an outer periphery of the outlet of the fan,
wherein the discharge guide comprises:
a first part extending along an upper edge of the outlet, the first part being located adjacent to the upper edge of the outlet;
a second part bent and extending from one end of the first part, the second part being located adjacent to one side edge of the outlet; and
a third part bent and extending from an opposite end of the first part, the third part being located adjacent to an opposite side edge of the outlet.

13. The control box according to claim 12 , wherein the case further comprises:
a discharge hole formed in one surface of the case, the discharge hole facing the outlet of the fan, and
wherein the discharge guide is located between the discharge hole and the outlet of the fan.

14. The control box according to claim 13 , wherein the case further comprises:
at least one introduction hole formed in another surface of the case.

15. The control box according to claim 14 , wherein the discharge hole is located closer to an upper surface of the case than the at least one introduction hole.

16. The control box according to claim 2 , further comprising:
a power supply located between the first plate and the second plate, the power supply being mounted on the first plate; and
a main board located between the second plate and the third plate, the main board being mounted on the second plate.

17. The control box according to claim 16 , wherein an amount of heat generated from the main board is greater than an amount of heat generated from the power supply.

18. The control box according to claim 17 , wherein an amount of heat generated from the transceiver is greater than an amount of heat generated from the main board.

19. The control box according to claim 2 , further comprising:
an insulating layer covering an upper surface of the first plate.

20. A display device comprising:
a head comprising a display panel,
wherein the head exchanges information with the transceiver of the control box described in claim 1 .
