More Information
Summary:A cart unit and a smart stroller including the same are disclosed. According to an embodiment of the present invention, a cart unit comprises a pressure sensor which detects the magnitude and direction of a force applied by a user to a handle part. The pressure sensor is coupled to a bearing and a vertical part provided in an inner space of the handle part, respectively, and does not rotate regardless of the rotation of the handle part. Accordingly, even when the handle part is rotated at an arbitrary angle, the pressure sensor may accurately detect the magnitude and direction of the force applied to the handle part. 카트부 및 이를 포함하는 스마트 유모차가 개시된다. 본 발명의 실시 예에 따른 카트부는 사용자가 핸들부에 인가하는 힘의 크기 및 방향을 감지하는 압력 센서를 포함한다. 압력 센서는 핸들부의 내부 공간에 구비되는 베어링 및 수직부에 각각 결합되어, 핸들부의 회전에 무관하게 회전되지 않는다. 이에 따라, 핸들부가 임의의 각도로 회전되는 경우에도, 압력 센서는 핸들부에 인가되는 힘의 크기 및 방향을 정확하게 감지할 수 있다.
