Abstract

The objective of the present invention is to provide a vehicle charging robot device, of which a robot for charging a vehicle is stored in a case, so as to protect the robot from external conditions including rain, wind, temperature, humidity, and the like, and prevent malfunction or failure, or damage to the robot.

First claim

The invention claimed is:

1 . A robot device for charging a vehicle using a charger fixed on the ground and having a charging gun connected to a vehicle for charging fuel or electricity, comprising:
a body part comprising a ceiling portion and a pillar portion, the pillar portion being fixedly formed on the same ground as the charger; a robot having one side connected to the ceiling portion and movable within a radius of the ceiling portion, and another side holding the charging gun; a case formed in the body part, having one surface thereof openable and closable, and storing the robot therein; and a central control unit capable of communicating with an outside, formed in the body part, and controlling the body part, the robot, and the case.

2 . The robot device of claim 1 ,
wherein the case stores the robot therein when there is no entry or exit of the vehicle or in a standby state where charging of the vehicle is unnecessary.

3 . The robot device of claim 1 ,
wherein the case is formed in a position close to the ground among the pillar portion.

4 . The robot device of claim 1 ,
wherein the case is formed in the ceiling portion, and the one surface thereof is openable and closable to discharge the robot downwardly from the ceiling portion.

5 . The robot device of claim 1 ,
wherein the case further comprises a temperature regulating device for heating or cooling an inside of the case.

6 . The robot device of claim 5 ,
wherein the temperature regulating device comprises one or more among a heater, an air-conditioner, a blower fan, or a heating wire.

7 . The robot device of claim 5 ,
wherein the case comprises: a second temperature sensor formed on an outside of the case; and a third temperature sensor formed inside the case, and wherein the central control unit controls the temperature regulating device using one or more values measured by the second temperature sensor or the third temperature sensor.

8 . The robot device of claim 5 ,
wherein the case comprises: a first humidity sensor formed on an outside of the case; and a second humidity sensor formed on an inside of the case, wherein the central control unit controls the temperature regulating device using one or more values measured by the first humidity sensor or the second humidity sensor.

9 . The robot device of claim 1 ,
wherein the case further comprises a brush part formed inside the case and cleaning a foreign substance on a surface of the robot.

10 . The robot device of claim 1 ,
wherein the case further comprises an air gun formed inside the case and spraying air onto the surface of the robot.

11 . The robot device of claim 1 ,
wherein the ceiling portion is formed in a certain length or a certain area along an extension direction of the ceiling portion, and further comprises a rail on which the robot or the case moves.

12 . The robot device of claim 11 ,
wherein the rail comprises a linear motor, a ball screw, a lead screw and a rack-and-pinion.

13 . The robot device of claim 11 ,
wherein two or more rails are installed thereon, and the robot is installed on each of the rails.

14 . The robot device of claim 13 ,
wherein the number of rails is less than the total number of vehicles which are chargeable.

15 . The robot device of claim 11 ,
wherein the ceiling portion rotates with respect to the pillar portion, and one side of the robot is connected to the ceiling portion and a position of the robot is changed according to rotation of the ceiling portion.

16 . The robot device of claim 1 , comprising:
a body part connecting portion formed at one end and connected to the body part; a grip part formed at another end to hold the charging gun; a plurality of length parts connecting the body part connecting portion and the grip part; and a link part formed between the plurality of length parts to connect the length parts to each other, and comprising a motor and a speed reducer.

17 . The robot device of claim 16 , further comprising:
a first temperature sensor formed in the link part, wherein the central control unit heats the motor, when a temperature measured by the first temperature sensor is less than a predetermined reference temperature.

18 . The robot device of claim 16 ,
wherein the link part further comprises: a discharge hole for discharging water droplets inside the link part to an outside due to condensation.
