Abstract

A guidance robot according to an embodiment of the present disclosure includes a display, a head case configured to be provided to be capable of rotating, an upper case configured to couple to the display and the head case, the upper case being configured to receive an electronic component and a cooling fan therein, and a lower case configured to be located on a lower side of the upper case, the lower case being configured to locate a wheel and a motor therein. In addition, when the cooling fan is driven, outside air is suctioned through a gap between a lower end portion of the head case and an upper-end portion of the upper case, and the suctioned air passes through the electronic component and then is discharged to the outside through the gap between the lower end portion of the upper case and the upper-end portion of the lower case.

First claim

The invention claimed is:

1. A guidance robot comprising:
a display;
a head case configured to be provided to be capable of rotating;
an upper case configured to couple to the display and the head case, the upper case being configured to receive an electronic component and a cooling fan therein; and
a lower case configured to be located on a lower side of the upper case, the lower case being configured to locate a wheel and a motor therein,
wherein, when the cooling fan is driven, outside air is suctioned through a gap between a lower end portion of the head case and an upper-end portion of the upper case, and the suctioned air passes through the electronic component and then is discharged to the outside through the gap between the lower end portion of the upper case and the upper-end portion of the lower case.

2. The guidance robot of claim 1 , further comprising:
a base plate configured to be located inside the upper case, the base plate being configured to dispose the cooling fan thereon; and
a middle plate configured to be located above the base plate, the middle plate being configured to dispose the electronic component therein;
wherein an opening through which the air suctioned into the upper case passes is formed in the middle plate.

3. The guidance robot of claim 2 , wherein the opening is located to overlap the cooling fan in a vertical direction.

4. The guidance robot of claim 2 , further comprising:
an upper plate configured to be located inside the lower case, the upper plate being configured to dispose a rider for autonomous driving,
wherein the upper portion of the lower case is formed with a cutout to be cut along a circumference of the lower case for the operation of the rider.

5. The guidance robot of claim 4 , wherein the air suctioned through the gap between the lower end portion of the head case and the upper-end portion of the upper case is discharged to the outside through the cutout after passing through the cooling fan.

6. The guidance robot of claim 2 , wherein a pair of cooling fans are provided, and
wherein the base plate is disposed to be adjacent to the lower end portion of the upper case.

7. The guidance robot of claim 6 , wherein the pair of cooling fans have the same rotation direction as each other.

8. The guidance robot of claim 6 , wherein rotation directions of the pair of cooling fans are directions opposite to each other.

9. The guidance robot of claim 8 , wherein one of the pair of cooling fans guides so as to suction the outside air to the inside of the upper case, and
wherein the other thereof guides to discharge the air suctioned into the inside of the upper case to the outside.

10. The guidance robot of claim 2 , wherein the base plate is formed to have a diameter larger than the diameter of the middle plate.

11. The guidance robot of claim 2 , further comprising:
a subframe configured to connect the base plate and the middle plate,
wherein the subframe is formed perpendicular to the upper surface of the base plate.

12. The guidance robot of claim 11 , further comprising:
a top plate configured to be located above the middle plate, the top plate being configured to support the head case; and
a main frame configured to connect the middle plate and the top plate,
wherein the main frame is formed perpendicular to the upper surface of the middle plate.

13. The guidance robot of claim 12 , further comprising:
a PC supporter configured to be coupled to the main frame,
wherein the PC supporter holds and supports a main PC.
