Description

Robot cleaner with cable sensor

The present invention relates to a robot cleaner having a cable sensor, and more particularly, to an obstacle detecting sensor of a robot cleaner, the robot cleaner main body of which is continuously moved and cleaned by a setting automatically set by a user; A cable sensor installed at an outer circumference of the main body of the robot cleaner and generating a voltage by an external pressure to sense an object around the robot cleaner; A sensor connector installed between the cable sensor and the robot cleaner main body to transmit a signal generated from a cable sensor to a controller configured in the robot cleaner main body, and to connect the cable sensor to the robot cleaner main body; And a bumper installed between the outer periphery of the robot cleaner body and the cable sensor to protect the robot cleaner body from impact of collision when the robot cleaner body hits a wall or an obstacle. It's about a robot cleaner.

In general, a robot cleaner detects a cleaning area and an obstacle by using a sensor by a command of a control unit, automatically cleans by driving the cleaning area, and the battery power inside the device is exhausted. When the charging unit is moved to a charging station provided separately at a predetermined position, and after the charging is completed, the cleaning device returns to the original position where the cleaning was performed again.

In addition, the robot cleaner detects an obstacle in the cleaning area and cleans the obstacle before driving the cleaning area. However, in some cases, the robot cleaner may encounter an obstacle not detected in advance while driving. In this case, the bumper is installed on the front surface of the main body and the driving information is generated at the same time as the controller detects the bumper and runs to avoid obstacles.

A general robot cleaner detects and avoids obstacles and walls around it as a sensor, and it does not detect any obstacles or people around it and the cleaner is broken. Because of the use of sensors, signal processing is complicated and the sensors are very expensive.

The present invention has been made in order to solve the above problems, and install a bumper surrounding the outer peripheral edge of the robot cleaner, the cable sensor is installed on the inside of the bumper to detect an external obstacle in all directions The purpose is to provide a robot cleaner equipped with.

The present invention is to install a bumper surrounding the outer periphery of the robot cleaner, a cable sensor is installed inside the bumper to detect the external obstacles in all directions, so that the bumper absorbs external shocks It protects the robot cleaner and detects the collision with obstacles located around the cleaner by the cable sensor installed inside the bumper, thereby avoiding the robot cleaner from being damaged and improving the cleaning efficiency.

The present invention provides an obstacle detecting sensor of a robot cleaner, the robot cleaner main body (10) of cleaning and continuously moving by a setting automatically set by a user; A cable sensor 20 installed at an outer circumference of the robot cleaner main body 10 and generating a signal by external pressure to detect an object around the robot cleaner; Installed between the cable sensor 20 and the robot cleaner main body 10 to transmit a signal generated from the cable sensor 20 to the control unit configured in the robot cleaner main body 10, the cable sensor 20 to the robot cleaner main body A sensor connector 21 for connecting with 10; The bumper 30 installed between the outer circumference of the robot cleaner main body 10 and the cable sensor 20 to protect the robot cleaner main body 10 from impact of collision when the robot cleaner main body 10 hits a wall or an obstacle. It is configured to include.

In this case, one or more sensor connectors 21 are installed between the cable sensor 20 and the robot cleaner main body 10.

In addition, the cable sensor 20 uses any one of a piezoelectric cable, a tape switch, and an air tube switch.

That is, the following describes the present invention in more detail.

A bumper 30 that protects the robot cleaner body 10 when colliding with an external object is installed on the outer circumference of the robot cleaner that cleans the room or moves automatically set by the user, and the inside of the bumper 30. Install the cable sensor 20 and connect the robot cleaner main body 10 and the cable sensor outside the bumper 30 with the sensor connector 21 to detect the external pressure detected by the one cable sensor 20. It is connected to the control unit inside the main body 10.

At this time, the sensor connector 21 is installed between the cable sensor 20 and the robot cleaner main body 10, one or more are installed using one cable sensor 20 or using a plurality of cable sensors 20. Will be detected.

In this case, when the cable sensor 20 is made of one, it detects the time difference of the signal transmitted from the pressure is applied to detect the position where the pressure is applied according to the time, in the case of using a plurality of cable sensors 20 Detected by the cable sensor 20 is detected by the cable sensor 20 of the section to which pressure is applied.

In addition, the cable sensor 20 selects any one of a tape switch or an air tube switch as well as a piezoelectric cable sensor.

1 is a plan view in which one sensor connector is installed in a robot cleaner having a cable sensor according to the present invention;

2 is a plan view in which a plurality of sensor connectors are installed in the robot cleaner having a cable sensor according to the present invention to identify a collision position for each section;

Figure 3 is a side view of the robot cleaner with a cable sensor according to the present invention.
