ABSTRACT:
The present invention provides a bumper structure for an automatic moving device which directs the moving device to change directions when bumping into an obstacle. The bumper structure of the present invention comprises a base, an elastic housing and a conductive terminal. A plurality of conductive sheets is formed over the base, wherein the conductive sheets are coupled to the control circuit of a moving device via the base. The elastic housing is formed over the base, with a protruding actuator section formed within the elastic housing, and the actuator section is parallel to the conductive sheets. The conductive terminal is formed at the bottom of the actuator section but is not in contact with the conductive sheets. The elastic housing may provide buffer when bumping into an obstacle, and the force generated by the impact presses the actuator section downwards, allowing conductive terminal of the actuator section to couple with the plurality of conductive sheets, thereby connects the plurality of conductive sheets and sends a signal to the control circuit of the moving device, directing the moving device to change directions.
