Abstract
Description
본 발명은 무한궤도를 구비한 전동스쿠터와 전동휠체어에 관한 것으로서 고르지 못한 노면이나 돌출 되어진 장애물, 구조물의 틈새에 바퀴가 빠지는 것을 방지하고 빙판길 등에서도 안전하게 운행을 할 수 있도록 구성한 것이다.The present invention relates to an electric scooter with an endless track and an electric wheel chair to prevent uneven road surface or protruding obstacles, to prevent wheels from falling into the gap of the structure, and to be able to safely drive even on an icy road.
일반적으로 종래의 전동스쿠터와 전동휠체어는 바퀴도 적을뿐 아니라 차체도 협소하여, 약간 돌출되어진 장애물이나 구조물의 틈새에 바퀴가 빠져 애로를 겪는 일이 다반사였으며, 빙판길 또는 눈비가 내리는 날에는 아예 운행을 포기할 수 밖에 없는 실정이었다.Generally, conventional electric scooters and electric wheelchairs have not only a few wheels but also a narrow body, and it is a common problem that wheels fall through a slightly protruding obstacle or structure gap, and it runs at all on ice roads or snowy days. There was no choice but to give up.
본 발명은 전동스쿠터와 전동휠체어에 무한궤도를 구비·축설 하므로서 상기와 같은 애로점을 해결함과 동시에 안전한 운행을 도모할 수 있도록 한 것이다.The present invention is to provide an endless track in the electric scooter and the electric wheelchair to solve the above problems and to ensure safe driving.
이상에서 설명한 바와 같이, 본 발명은 운행시 주위 여건에 의하여 애로를 겪는 종래의 전동스쿠터와 전동휠체어에 무한궤도를 구비 하므로서 보다 안전한 운행을 도모할 수 있도록 한 것이다.As described above, the present invention is to provide a safer trajectory to the conventional electric scooter and the electric wheelchair that suffers due to the ambient conditions during operation.
전동스쿠터와 전동휠체어의 바퀴외부에 고무 혹은 금속재질로 이루어진 무한궤도(1)를 축설하고, 구동바퀴(2)의 접지면에 구동돌기(3)를 형성하여, 바퀴가 구동하게 되면 무한궤도의 내면 중앙에 형성된 구동돌기 결착홈(5)에서 이루어지는 구동바퀴(2)와 구동돌기(3)의 회전력에 의하여 운행하게 되며, 지지바퀴(4)와 앞바퀴(7)는 구동돌기 결착홈(5)에 결속되어 회전하게 되므로 구동바퀴의 구동돌기(3)와 더불어 무한궤도(1)가 이탈되지 않고 구동할 수 있게 되는 것이다. 무한궤도 차량의 방향전환에 관한 것은 통상적 구성이므로 그 구성의 상세한 설명은 생략한다.An endless track (1) made of rubber or metal is laid out on the outside of the wheel of the electric scooter and the electric wheel chair, and a driving protrusion (3) is formed on the ground surface of the driving wheel (2). It is driven by the rotational force of the
