Abstract

The guide robot includes a case having a coupling hole and a door type display structure that is capable of opening or closing the coupling hole. Access to the body part in which main electrical components are provided may be easy. An installation plate coupled to a main frame, a slide guide and a guide plate, which are coupled to the installation plate, and a plurality of link type coupling devices coupled to one side of the guide plate and connected to the display unit may be provided to open or close the coupling hole by rotating the display unit after the display unit slidably moves.

First claim

What is claimed is:

1. A guide robot comprising:
a lower section having a motor and a plurality of wheels connected to the motor;
a body section provided above the lower section and having at least one lidar and a movable guide that slidably moves forward and backward;
a head section rotatably provided above the body section;
a case covering the body section and having an opening so that an inside of the body section is accessible and allows the movable guide to move into or out of the body section; and
a door connected to the moveable guide to open or close the opening,
wherein the body section further includes an installation plate having a space which restricts a movement distance of the movable guide,
wherein the movable guide comprises:
a slide guide coupled to the installation plate;
a slider allowing the slide guide to be inserted therein to slidably move; and
a guide plate connected to the slider to be movable forward and backward, and

wherein the guide plate comprises:
a first guide plate coupled to the slider; and
a second guide plate releasably connected to the first guide plate.

2. The guide robot according to claim 1 , wherein the door comprises:
a display;
a display cover accommodating the display; and
a display support protruding from the display cover to open or close the opening.

3. The guide robot according to claim 1 , wherein the door is rotatably connected to the movable guide.

4. The guide robot according to claim 1 , wherein the moveable guide further includes a stopper to contact a wall defining the space to restrict the movement distance.

5. The guide robot according to claim 1 , wherein the second guide plate is connected to the door.

6. The guide robot according to claim 1 , wherein a section of the second guide plate is inserted into a section of the first guide plate to connect the second guide plate to the first guide plate.

7. The guide robot according to claim 1 , wherein the second guide plate is detachably seated on the first guide plate to connect the second guide plate to the first guide plate.

8. The guide robot according to claim 1 , wherein the first guide plate includes:
a cutout region provided at an upper end of the first guide plate and supporting the second guide plate; and
a first assembly region that includes a recessed surface under the cutout part.

9. The guide robot according to claim 8 , wherein the second guide plate includes a second assembly region having a surface corresponding to the recessed surface of the first assembly region included in the first guide plate,
wherein the second assembly region contacts the first assembly region when the second guide plate is connected to the first guide plate.

10. The guide robot according to claim 1 , further comprising at least one hinge provided on the movable guide and coupled to the door.

11. The guide robot according to claim 10 , wherein the at least one hinge is coupled to the second guide plate.

12. The guide robot according to claim 10 , wherein the at least one hinge includes:
a support plate coupled to the movable guide; and
a first link rotatably connected to the support plate.

13. The guide robot according to claim 12 , wherein the at least one hinge further includes a second link rotatably connected to the first link.

14. The guide robot according to claim 13 , wherein the at least one hinge further includes an attachment plate having one end connected to the second link and the other end coupled to the door.

15. The guide robot according to claim 14 , wherein the at least one hinge further includes a third link rotatably connected to the support plate and spaced apart from the first link.

16. The guide robot according to claim 15 , wherein the at least one hinge further includes a fourth link rotatably connected to the third link.

17. The guide robot according to claim 1 , further comprising a fastener that is inserted through a first opening in the first guide plate and a second opening in the guide plate to couple together the first guide plate and the guide plate.
