Description

수동 휠체어의 전동화 장치{The convertible device of manual wheelchair into electro-powered wheelchair}The convertible device of manual wheelchair into electro-powered wheelchair

본 발명은 수동 휠체어의 전동화 장치에 관한 것으로, 더욱 상세하게는 동력원(구동모터)과 구동부(휠축)이 체인이나 벨트와 같은 별도의 동력 전달 장치 없이 기어를 통해 직접 연결되는 전동화 장치에 관한 것이다.The present invention relates to a motorized device for a manual wheelchair, and more particularly, to a motorized device in which a power source (drive motor) and a drive unit (wheel shaft) are directly connected through a gear without a separate power transmission device such as a chain or a belt. will be.

기존의 전동 휠체어는 동력원과 구동부가 간접적으로 연결되어 동력 전달시 효율이 감소한다는 점과 가격 면에서 비싸다는 이유로 인하여 보급이 일반화되지 못하고 있다는 점이 있으며 또한 운전자의 사용목적에 따라서 전동휠체어에서 수동휠체어로의 전환이 불가능하다는 단점을 지니고 있다.Existing electric wheelchairs are indirectly connected due to the fact that the power source and the driving part are indirectly connected, which reduces the efficiency of power transmission and is expensive in terms of price. Has the disadvantage of being impossible to switch.

본 발명은 상술한 문제점을 해결하기 위하여, 동력원(구동모터)과 구동부(휠축)사이에 동력 전달 효율이 높은 기어를 사용하여 직접 연결함으로서 동력손실을 최소화하고, 필요시 동력원(구동모터)과의 연결 및 단절이 가능하도록 하여 전동 및 수동 휠체어로의 전환이 가능한 전동화 장치를 제작하는 것을 목적으로 한다.In order to solve the above problems, the present invention minimizes the power loss by directly connecting the power source (drive motor) and the drive unit (wheel shaft) by using a gear having high power transmission efficiency, and when necessary, the power source (drive motor) It is an object of the present invention to manufacture a motorized device capable of connecting and disconnecting and switching to an electric and manual wheelchair.

본 발명은 배터리(①), 구동모터(②), 구동축(③), 클러치(④), 운전손잡이(⑤)로 구성되어 서로 결합되어 사용되는 휠체어용 전동 동력 장치이다.The present invention consists of a battery (①), drive motor (②), drive shaft (③), clutch (④), the driving handle (⑤) is an electric power device for wheelchair used in combination with each other.

휠체어 주행시 똑같은 크기의 힘의 양쪽 휠에 동시에 전달된다면, 휠체어는 전진 내지 후진만 가능하게 된다.If wheelchairs are simultaneously transferred to both wheels of the same size, the wheelchair will only be able to move forward or backward.

따라서, 양쪽의 휠을 따로 제어하기 위하여 두 개의 구동모터(②)를 각각 사용하였으며, 이로 인하여 휠체어는 전진 및 후진뿐만 아니라 선회하는 경우에도원활한 주행을 할 수 있게 된다.Therefore, two driving motors (②) were used to control both wheels separately, thereby allowing the wheelchair to move smoothly even when turning as well as forward and backward.

상기 구동모터(②)에는 감속기와 기어가 내장되어 있는 하나의 하우징 형태로 되어 있으며, 체인이나 벨트가 아닌 기어로서 직접 연결되기 때문에 동력 전달시 발생되는 손실을 줄일 수 있다.The drive motor (②) is in the form of a single housing in which the reducer and the gear are built in, and are directly connected as a gear instead of a chain or a belt, thereby reducing a loss generated during power transmission.

그리고, 구동모터(②)와 구동축(③)사이에는 클러치(④)를 사용하여 필요에 따라 동력을 연결 또는 단절할 수 있도록 하여 수동 휠체어 및 전동 휠체어로의 겸용사용이 가능하도록 하였다.And, between the drive motor (②) and the drive shaft (③) by using the clutch (④) to connect or disconnect the power as needed to enable the combined use of the manual wheelchair and electric wheelchair.

또한 무게중심을 고려하여 구동모터(②)와 배터리(①)를 휠체어의 전면부에 위치시킴으로서 주행시 휠체어의 안정성이 더욱 높아지도록 하였다.In addition, by placing the driving motor (②) and the battery (①) in front of the wheelchair in consideration of the center of gravity to improve the stability of the wheelchair while driving.

한편, 우측 팔걸이(⑥) 옆에는 구동모터(②)와 연결되어 있는 운전손잡이(⑤)를 부착하여 운전자의 조작이 용이하도록 하였으며, 도 5에서 보는 바와 같이, 사용자의 신체조건에 따라 운전손잡이의 위치를 조정할 수 있게 하였다.On the other hand, next to the right armrest (⑥) attached to the driving handle (⑤) connected to the drive motor (②) to facilitate the operation of the driver, as shown in Figure 5, according to the user's physical condition of the driving handle The position can be adjusted.

이상에서 설명한 바와 같이, 본 발명에 의한 수동 휠체어의 전동화 장치를 사용하여 기존의 휠체어에 장착할 경우, 고가인 기존의 전동휠체어에 대한 대체요과를 얻을 수 있어 지체 부자유자의 경제적인 부담을 줄일 수 있다.As described above, when mounted on an existing wheelchair using the electric wheelchair of the manual wheelchair according to the present invention, it is possible to obtain a replacement demand for the expensive existing electric wheelchair can reduce the economic burden of the handicapped person have.

또한, 자동 및 수동의 겸용 사용이 가능하므로, 장애의 정도가 심하지 않은 운전자가 사용할 경우에는 운동 및 재활목적으로의 사용도 가능하며, 배터리를 교체할 수 있어 반영구적으로 사용할 수 있다.In addition, it is possible to use a combination of automatic and manual, so that when the driver is not severely disabled can be used for exercise and rehabilitation, and can be used semi-permanently because the battery can be replaced.
