A kind of clutch power-down control device of electric wheelchair driver,Be one be installed in wheelchair chair frame,And for the driver of installing and turn wheel,The driver include be equipped in a shell power input wheel unit driven by motor,And one driven by power input wheel unit and have and to install the force-output shaft of wheel gone out wheels unit,And installing one can stir out the clutch gear on wheels unit on shell,Be engaged between the relay gear on power input wheel unit or disengaging operation clutch operating lever,Element is stirred containing the triggering rod unified its outboard end connection one and can touch a microswitch on the wheel hub of clutch gear simultaneously,And then when clutch operating lever switch to the position of electric drive to be carried out,When clutch gear does not but engage with relay gear or is not at a fully engaged,In the state of enabling triggering rod still end completely disengage what microswitch,The electric drive of wheelchair is allowed to remain powered off state and can not start,And then under non-meshing state,It avoids single wheel error starting and occupant is allowed to cause danger,Make the operation more safety of clutch certain.一種電動輪椅驅動器的離合斷電控制裝置，是一裝設在輪椅椅架上、且為用以裝設並驅轉輪子的驅動器，該驅動器包括一殼體內設有受馬達帶動的入力輪單元、以及一受入力輪單元帶動而具有用以裝設輪子之出力軸的出力輪單元，且在殼體上裝設一可以撥動出力輪單元上之離合齒輪，與入力輪單元上的中繼齒輪之間進行嚙合或脫離之操作的離合操作桿，同時離合齒輪的輪轂上含合一其外側端連結一可觸動一微動開關之觸動桿的撥動元件，進而當離合操作桿撥轉至欲進行電動驅動的位置時，離合齒輪卻未與中繼齒輪嚙合或未完全嚙合時，令觸動桿仍末完全脫離於微動開關的狀態下，讓輪椅的電動驅動仍保持斷電狀態而無法啟動，進而在未嚙合狀態下，避免單一輪子誤啟動而讓乘坐者發生危險，讓離合的操作更加安全確實。
