Description

후방 조향 장치가 구비된 전동차Electric vehicles with rear steering
본 발명은 후방 조향 장치가 구비된 유아용 전동차에 관한 것으로서, 더욱 상세하게는 아이가 단독으로 탑승하거나 또는 성인과 함께 탑승할 수 있을 뿐만 아니라 후방에서 탑승자가 선 자세로 전동차를 조향할 수 있도록 한 후방 조향 장치가 구비된 전동차에 관한 것이다. The present invention relates to an infant electric vehicle equipped with a rear steering device, and more particularly, a rear that allows a child to ride alone or with an adult, as well as to steer the electric vehicle in a standing posture from the rear. It relates to an electric vehicle equipped with a steering device.
최근 들어 수동식 또는 전동식 유아용 자동차들이 많이 개발되어 제품화되고 있으나, 이들 중 수동식 유아용 자동차는 단순히 앞바퀴와 뒷바퀴가 각각의 중심축 양단에 결합된 상태에서 임의 구동되는 구조로 되어 있다. Recently, many manual or electric baby cars have been developed and commercialized, but among them, the manual baby car has a structure in which the front wheel and the rear wheel are simply driven in a state in which both front and rear wheels are coupled to both ends of the central axis.
그리고 종래의 수동식 유아용 자동차는 주행하기 위해서는 차체에 탑승한 상태에서 양쪽 발로 지면을 박차면서 차체를 밀어야 되기 때문에 속도감을 느낄 수 없어 쉽게 싫증을 낸다는 문제가 있을 뿐만 아니라 좁은 공간에서 즐길 수 없는 문제점이 있었다. In addition, the conventional manual infant car has a problem in that it is not easy to feel tired because it has to push the body while pushing the ground with both feet in the state of boarding the car, and it is not easy to enjoy it in a narrow space. .
또한 종래의 수동식 유아용 자동차는 발로 지면을 차야 하기 때문에 다리에 힘이 붙지 않은 아이들은 스스로 차체를 주행시킬 수 없는 문제점이 있었다. In addition, the conventional manual infant car has a problem that children who do not have the power to drive the body by themselves because they have to kick the ground with their feet.
한편, 전동식 유아용 자동차는 상기와 같은 수동식 유아용 자동차의 단조로움을 개선할 수 있는 것으로서, 바퀴의 회동이 배터리에 의해 동작하는 모터의 구동력에 의해 이루어짐에 따라 차체가 주행되고, 조향핸들의 수동조작에 의하여 방향 전환이 이루어질 수 있다.
