Abstract

According to an embodiment of the present disclosure, a mobile robot may include a body provided with a driving unit, a body display unit positioned on an upper side of a front portion of the body, extending vertically, and provided with a display on a front surface thereof, a supporter extending vertically inside the body display unit and having a lower end supported by the body, and an interface module supported by the supporter and electrically connected to the display.

First claim

The invention claimed is:

1. A mobile robot, comprising:
a body, the body including a driver configured to move the mobile robot;
a vertically extending body display unit located at an upper side of a front portion of the body, the body display unit having a front surface and a rear surface;
a display located at the front surface of the body display unit;
a vertically extending supporter located inside the body display unit, the supporter having a lower end supported by the body;
an interface module supported by the supporter, the interface module being electrically connected to the display;
a head display unit rotatably connected to an upper portion of the body display unit;
a rotating motor disposed inside the body display unit;
a vertically extending rotating shaft connecting the rotating motor to the head display unit to rotate the head display unit; and
a motor mount on which the rotating motor is mounted, the motor mount being supported by the supporter.

2. The mobile robot of claim 1 , wherein the body display unit has a lower opening portion at a lower end thereof, and
wherein the supporter extends through the lower opening portion of the body display unit.

3. The mobile robot of claim 1 , further comprising an inner bracket configured to fasten the supporter to an inner surface of the body display unit.

4. The mobile robot of claim 1 , wherein the interface module includes:
a module case fastened to the supporter; and
an interface printed circuit board located in the module case.

5. The mobile robot of claim 1 , wherein a weight of the head display unit is supported by the supporter.

6. The mobile robot of claim 1 , further comprising at least one speaker disposed inside the body display unit, the at least one speaker being spaced apart from the motor mount, the at least one speaker being supported by the body display unit.

7. The mobile robot of claim 6 , wherein the at least one speaker is spaced apart from the supporter.

8. The mobile robot of claim 6 , wherein a vertical distance from a top surface of the body display unit to a top of the rotating motor or a top of the supporter is longer than a vertical distance from the top surface of the body display unit to a bottom surface of the speaker.

9. The mobile robot of claim 6 , further comprising an audio unit located inside the body display unit, the audio unit being electrically connected to the speaker, the audio unit being supported by the supporter.

10. The mobile robot of claim 1 , further comprising:
a shaft support portion configured to rotatably support an end of the rotating shaft, the shaft support portion being spaced from the motor mount; and
at least one vertically extending support shaft located between the shaft support portion and the motor mount.

11. The mobile robot of claim 10 , wherein the at least one support shaft comprises a plurality of support shafts.

12. The mobile robot of claim 11 , wherein the shaft support portion includes:
an annular portion connected to the end of the rotating shaft; and
a plurality of protrusions protruding from the annular portion in a radially outward direction, and
wherein each support shaft of the plurality of support shafts is connected to a corresponding one of the plurality of protrusions.

13. The mobile robot of claim 1 , further comprising:
a module support plate configured to support a service module, the module support plate being located behind the body display unit; and
a plate mounting portion on which the module support plate is mounted, the plate mounting portion being located on the body,
wherein the plate mounting portion is connected to the body display unit.

14. The mobile robot of claim 1 , further comprising a hub unit disposed inside the body display unit, the hub unit being electrically connected to the interface module, the hub unit being supported by the supporter.

15. A mobile robot, comprising:
a body, the body including a driver configured to move the mobile robot;
a vertically extending body display unit located at an upper side of a front portion of the body, the body display unit having a front surface and a rear surface;
a display located at the front surface of the body display unit;
a head display unit rotatably connected to an upper portion of the body display unit;
a vertically extending supporter located inside the body display unit, the supporter having a lower end supported by the body;
a rotating motor disposed inside the body display unit, the rotating motor being supported by the supporter to rotate the head display unit; and
a speaker located inside the body display unit, the speaker being supported by the body display unit.

16. The mobile robot of claim 15 , wherein the speaker is spaced apart from the rotating motor and the supporter.

17. The mobile robot of claim 15 , wherein the head display unit includes:
a neck housing rotatably connected to the body display unit; and
a head housing connected to the neck housing, the head housing being spaced apart from the body display unit,
wherein the rotating motor is located under the neck housing, and
wherein the speaker is located beside the neck housing.

18. The mobile robot of claim 15 , further comprising:
a vertically extending rotating shaft connecting the rotating motor to the head display unit to rotate the head display unit; and
a motor mount on which the rotating motor is mounted, the motor mount being supported by the supporter.
