ASSISTANT POWER APPARATUS FOR WHEELCHAIR AND CONNECTION ASSEMBLY BETWEEN ASSISTANT POWER APPARATUS AND WHEELCHAIR

摘要

The present invention, an electric module for generating a driving force based on the electric power; A link module having a connection link and coupled to a wheelchair to be towed by the driving force; And a coupling module detachably coupling the power module and the link module, the coupling module comprising: a first coupling unit installed in the power module and having an open recess; And a second coupling unit seated on the opened recess portion and having a central rod portion which is a part of the connection link, wherein the electric module is rotated relative to the link module for coupling with the link module. At this time, the open recess portion provides a connection assembly between the auxiliary power device for a wheelchair and the auxiliary power device used therein, which is rotated relative to the central rod part as a rotation central axis.
