Abstract

A mobile robot includes a driver configured to provide a traveling function, a body disposed at an upper side of the driver, and formed to include an inclined surface protruding downward at front and rear surfaces thereof, a body frame disposed in the body, and one pair of displays coupled to the body frame, and disposed at front and rear surfaces of the body. The body frame includes body profiles disposed at left and right sides of the body frame, and formed to extend in a vertical direction, and display supports fixed to the body profiles to extend in forward and backward directions, and respectively coupled to the pair of the displays.

First claim

What is claimed is:

1. A mobile robot comprising:
a driver configured to provide a traveling function;
a body disposed at an upper side of the driver, the body having a pair of inclined surfaces opposite each other and extending downward at front and rear surfaces of the body, respectively;
a body frame disposed in the body; and
a pair of displays located opposite each other and coupled to the body frame at the front and rear surfaces of the body, respectively,
wherein the body frame includes:
body profiles disposed at left and right sides of the body frame, the body profiles extending in a vertical direction; and
display supports fixed to the body profiles to extend in a forward and rearward direction, the display supports being coupled to the pair of displays.

2. The mobile robot according to claim 1 , wherein the display supports include:
an upper display support disposed at an upper portion of the body;
a lower display support disposed at a lower portion of the body; and
a middle display support disposed between the upper display support and the lower display support,
wherein the upper display support is shorter in length than the middle display support in the frontward and rearward direction, and
wherein the lower display support is longer in length than the middle display support in the frontward and rearward direction.

3. The mobile robot according to claim 2 , wherein the lower display support includes a pair of support portions disposed to support a lower end of each of the displays.

4. The mobile robot according to claim 3 , wherein each of the support portions is formed by bending the lower display support inwards.

5. The mobile robot according to claim 3 , further comprising a protrusion protruding from each of the support portions, the protrusions being fastened to the pair of displays.

6. The mobile robot according to claim 1 , wherein each display support further includes a wing portion formed to extend in a direction away from the respective display.

7. The mobile robot according to claim 6 , further comprising:
side reinforcement frames disposed at the left and right sides of the body frames, the side reinforcement frames being fastened to the wing portions of the display supports, and the side reinforcement frame extending in the vertical direction, and
a fastening protrusion protruding from a fastening portion of each of the side reinforcement frames, the fastening protrusion being coupled to a body case forming an outer appearance of the body.

8. The mobile robot according to claim 6 , wherein each wing portion comprises a portion of each display support cut in a U-shape and bent by 90°.

9. The mobile robot according to claim 1 , wherein each display support includes:
a metal plate having a bent portion formed at upper and lower portions of the metal plate; and
a pair of fastening holes, each fastening hole being configured to receive a fastener fastened to the body profile and a corresponding one of the displays of the pair of displays.

10. The mobile robot according to claim 1 , wherein each display is inclined along a corresponding one of the inclined surfaces of the body, and
wherein a display printed circuit board is coupled to a lower portion of each display.

11. The mobile robot according to claim 1 , wherein the body includes:
a concave portion disposed at a lower portion of each display, each concave portion being recessed inward from a corresponding one of the front and rear surfaces of the body;
a vent hole formed at an upper side of each concave portion; and
a guide inclined surface formed at a lower side of each concave portion, and
wherein, during traveling of the driver, air is introduced into the body through one of the vent holes.

12. The mobile robot according to claim 11 , further comprising:
a sound hole at each of the guide inclined surfaces; and
a speaker disposed in each of the sound holes.

13. The mobile robot according to claim 12 , further comprising a waterproof film disposed across each of the sound holes.

14. The mobile robot according to claim 12 , further comprising a vent roof cover covering each of the vent holes, each vent roof cover being disposed at an upper side of a corresponding one of the sound holes.

15. The mobile robot according to claim 12 , wherein each sound hole is located at an inner position relative to an outer end of the corresponding concave portion.

16. The mobile robot according to claim 1 , further comprising a head disposed at an upper portion of the body, the head including a head bracket inserted into the body,
wherein, when a first bolt fastened to the head bracket is released, the head is separable from the body.

17. The mobile robot according to claim 16 , wherein the body includes:
a head fixing frame fastened to the head bracket by the first bolt; and
a connection port disposed adjacent to the head fixing frame, and
wherein the head includes:
a head display disposed at a front surface of the head; and
a connection cable, the connection cable have a first end connected to the head display and a second end connected to the connection port.

18. The mobile robot according to claim 17 , wherein the head bracket defines an inner space in which three sides are closed and one side is opened, the inner space extending in a vertical direction, and
wherein the connection cable extends into the body along the inner space of the head bracket.

19. The mobile robot according to claim 18 , wherein the head bracket includes an opening, and
wherein the connection cable passes through the opening such that the second end of the connection cable is inserted into the connection port.

20. The mobile robot according to claim 1 , wherein the driver includes a traveling unit including a plurality of wheels.
