Abstract

A robot according to the present disclosure may include: a casing that has an internal space; a head unit that protrudes upward from the casing and has a first display; a display unit that is disposed ahead of the casing and has a second display; an ascending and descending motor that is disposed in the casing; an ascending and descending plate that ascends and descends between a first position and a second position higher than the first position by power of the ascending and descending motor; a contact bar that has an upper end connected to the head unit and a lower end being in contact with the ascending and descending plate; a fixing plate that is positioned between the ascending and descending plate and the head unit and has an opening through which the contact bar passes; and a link that connects the ascending and descending plate and the fixing plate to the display unit.

First claim

What is claimed is:

1 . A robot comprising:
a casing that has an internal space; a head unit that protrudes upward from the casing and has a first display; a display unit that is disposed ahead of the casing and has a second display; an ascending and descending motor that is disposed in the casing; an ascending and descending plate that ascends and descends between a first position and a second position higher than the first position by power of the ascending and descending motor; a contact bar that has an upper end connected to the head unit and a lower end being in contact with the ascending and descending plate; a fixing plate that is positioned between the ascending and descending plate and the head unit and has an opening through which the contact bar passes; and a link that connects the ascending and descending plate and the fixing plate to the display unit.

2 . The robot of claim 1 , wherein the contact bar is formed to increase in height and to bend close to verticality forward.

3 . The robot of claim 1 , wherein when the ascending and descending plate is at the first position, the first display is hidden in the casing, and when the ascending and descending plate is at the second position, the first display protrudes upward from the casing.

4 . The robot of claim 1 , wherein when the ascending and descending plate is at the first position, the display unit is in contact with the outer surface of the casing, and when the ascending and descending plate ascends to the second position, the display unit is spaced apart from the outer surface of the casing.

5 . The robot of claim 1 , wherein when the ascending and descending plate ascends, the direction that the first display faces and the direction that the second display faces are tilted upward.

6 . The robot of claim 5 , wherein when the ascending and descending plate ascends from the first position to the second position, the angular change amount of the direction that the first display faces is different from the angular change amount of the direction that the second display faces.

7 . The robot of claim 1 , further comprising a power transmitting part that transmits rotational force of the ascending and descending motor to the ascending and descending plate,
wherein the power transmitting part includes: a first arm that is connected to the ascending and descending motor; and a second arm that is rotatably connected to the first arm and is rotatably connected to the lower side of the ascending and descending plate.

8 . The robot of claim 1 , further comprising at least one guide bar that is vertically elongated, is connected to the fixing plate, and guides ascending and descending of the ascending and descending plate.

9 . The robot of claim 1 , further comprising a head receiving cover that is disposed over the fixing plate, has a through-hole through which the contact bar passes, and receives at least a portion of the head.

10 . The robot of claim 1 , wherein a link-through hole through which the link passes is formed through the casing.

11 . The robot of claim 1 , wherein the link includes:
a first link bar that is rotatably connected to a first connector disposed on the ascending and descending plate; and a second link bar that is rotatably connected to a second connector disposed on the fixing plate and forms a joint while crossing the first link bar.

12 . The robot of claim 1 , wherein the display unit includes:
a rear cover that covers the second display from behind; and a link connector that is fastened to the rear surface of the rear cover and to which the link is connected.

13 . The robot of claim 12 , wherein the link includes:
a first link bar that is rotatably connected to the link connector; and a second link bar that forms a joint while crossing the first link bar and is connected to be movable along an oblong hole formed in the link connector.

14 . The robot of claim 1 , further comprising a guide body that is fastened to the upper side of the fixing plate and guides movement of the contact bar.

15 . The robot of claim 14 , wherein a guide groove that is elongated in the longitudinal direction of the contact bar is formed at the contact bar, and a guide rib that is fitted in the guide groove is formed at the guide body.

16 . The robot of claim 1 , further comprising:
a base that is disposed under the casing; a column that protrudes upward into the casing from the base; an inner frame that is fastened to the column to be able to tilt; and a tilting motor that tilts the inner frame with respect to the column, wherein the casing and the inner frame are tilted together with respect to the base.

17 . The robot of claim 16 , wherein a tilting axis of the inner frame is spaced apart from the upper side of the tilting motor.

18 . The robot of claim 16 , further comprising a lever that transmits rotational force of the tilting motor to the inner frame,
wherein the lever includes: a motor connecting part that is connected to the tilting motor; a lever body that extends from the motor connecting part in a direction perpendicular to the rotational axis of the tilting motor; and an oblong hole inserting part that protrudes from the lever body in a direction parallel to the rotational axis of the tilting motor and is movably inserted a guide oblong hole formed in the inner frame.

19 . The robot of claim 16 , wherein a depression is formed to be recessed downward on the top surface of the base, and the casing is positioned over the depression.

20 . The robot of claim 16 , wherein the fixing plate and the ascending and descending motor are connected to and supported by the inner frame.
