Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power cord control structure, and more particularly to a mechanism for controlling the length of a power cord supplied to a cleaning robot that automatically travels to suck dust on a floor surface.

[0002]

[Prior Art]

 Conventionally, as shown in FIGS. 3 and 4, this type of cleaning robot has a cord reel 20 and a capstan 21 mounted in the cleaning robot 19 for feeding a power cord 22 from inside the cleaning robot 19, or for cleaning the robot. The cleaning robot 19 moves forward in response to a start command, and the power cord 22 wound on the cord reel 20 is unwound from the cleaning robot 19 by the capstan 21 and the power cord 22 is placed on the floor. It is placed on surface 23 (Fig. 4). When the cleaning robot 19 turns around (FIG. 4), the power cord 22 is fed out, and when returning (FIG. 4), the power cord 22 placed on the floor 23 is wound up inside the cleaning robot 19.

[0003]

[Problems to be solved by the device]

 In the conventional power cord control structure of a cleaning robot, the power cord is placed on the floor or placed on the floor by electrical control while detecting the distance to the wall surface with an ultrasonic sensor, an infrared sensor, etc. The capstan 21 is a system that winds the power cord, and also takes in the cord reel 20 or the power cord 22 that winds the power cord into the cleaning robot, or pulls out the power cord from the cleaning robot. Since it is mounted on the cleaning robot 19, it is necessary to perform a soft process to prevent the cleaning robot from stepping on the power cord placed on the floor, and dust on the floor adheres to the power cord, damaging the capstan surface or the power source. The cleaning robot is driven because the cord is unwound and the winding operation is abnormal, and the cleaning robot is heavy. A large current was required to.

Therefore, an object of the present invention is to adopt a power cord control structure that separates the power cord of the cleaning robot from the floor, remove the capstan, and install the cord reel outside the cleaning robot. The purpose of the present invention is to provide a power cord control structure in which the cleaning robot does not step on the power cord, dust does not adhere to the power cord, and the cleaning robot is lighter in weight.

[0005]

[Means for Solving the Problems]

 Therefore, in order to achieve the above-mentioned object, the present invention connects the power cord stand, the cord reel rotatably supported by the power cord stand, and the first Conston spring drum to the rotary shaft of the cord reel, and A Conston spring mechanism that rotatably supports the Conston spring drum on the power cord stand, a guide that is supported on the power cord stand, and a cord reel.One end extends through the guide and the other end plugs into an outlet. A power cord that extends so as to be connected, and the cord reel is rotated by the action of the Conston spring mechanism based on the force acting on one end of the power cord stand, so that the power cord can be fed out or wound up. The one end of the power cord is fixed inside the cleaning robot.

[0006]

[Action]

 According to this invention, the cord reel is located outside the cleaning robot and winds up the power cord extending from the cleaning robot, or extends the power cord to the cleaning robot. It has a joining function, the Conston spring mechanism gives rotational force to the cord reel, the guide guides the power cord, the power cord stand body is equipped with the above components, and the cleaning robot when not using the cleaning robot. By storing the cleaning robot, the cleaning robot can run without putting the power cord of the cleaning robot on the floor, and the cleaning robot is intended to be lighter.

[0007]

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS.

In the figure, a power cord control structure 1 has a power cord 5 having one end fixed inside a cleaning robot 2 and the other end fixed to a cord reel 4 of a power cord stand 3, The cord reel 4 having the other end fixed and the power cord 5 wound therein, and one (first) conston spring drum 6 are connected to the rotary shaft 7 of the cord reel 4, and the other (second) conston spring drum. 8 is a power cord stand body 9 which is supported by a power cord stand body 9 to rotate freely, a power cord 5 guide 11 mounted on the power cord stand body 9, a cord reel 4, and a power source which connects the outlet 12 of the room 12 to each other. A power cord cord that houses the cord 14 and the cleaning robot 2 and is attached with a cord reel 4, a conston spring mechanism 10, a guide 11, and a power cord 14. A power cord stand 3 including a stand body 9 is provided.

Next, the operation will be described. As shown in FIG. 2, when the cleaning robot 2 travels on the floor surface 15 and when the cleaning robot 2 travels in the direction 16 in which the tension of the power cord increases, the rotation axis is countered by the rotational force of the Conston spring mechanism 10. The cord reel 4 rotates around 7 by the tension of the power cord 5, and the power cord 5 is paid out from the cord reel 4. When the cleaning robot 2 travels in the direction 17 in which the tension of the power cord 5 decreases, the cord reel 4 rotates around the rotary shaft 7 due to the rotating force of the Conston spring mechanism 10, and the power cord 5 moves to the cord reel 4. Being rolled up. The rotating force of the conston beam mechanism 10 is constant. Therefore, if the tension of the conston spring 18, the frictional force between the cord reel 4 and the rotating shaft 7 and the height of the power cord stand body 9 are set appropriately, the power cord 5 is placed on the floor. The power cord 5 can be controlled away from the surface 15.

[0010]

[Effect of the device]

 As described above, according to the present invention, by providing the cord reel and the conston bar mechanism outside the cleaning robot and holding the power cord of the cleaning robot with an appropriate tension, it is possible to attempt to reduce the weight of the cleaning robot. Since the cleaning robot can be run while the power cord is away from the floor, it is no longer necessary to control the power cord processing on the floor by software, and the power cord can be unrolled and wound. By removing the capstan that is removed, the effect of dust adhering to the power cord was reduced.
