Description

TECHNICAL FIELD [0001] The present invention relates to an electric driving apparatus for removable,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric driving apparatus for attaching and detaching, and more particularly, to an electric driving apparatus for attaching and detaching an electric driving apparatus which can be easily attached to and detached from an existing driving apparatus, ≪ / RTI >

In general, a conventional non-powered transfer device such as a baby carriage or a shopping cart is provided with a handle so that the user holds the handle at the rear and pushes forward. Therefore, when moving in a sloping place or for a long time, there was an inconvenience that a lot of effort was required. On the other hand, an electric wheelchair or the like equipped with a power transmission device can move automatically, which is convenient for the user, but has a disadvantage in that it is heavy in weight.

In order to solve this problem, there is a need for an electric driving device capable of being carried and capable of selectively mounting and dismounting a stroller, a wheelchair, a shopping cart, and the like.

In this regard, a baby stroller having a motor-driven device installed on a baby stroller and configured to be able to automatically move at a low speed while carrying a protector with an infant is disclosed in Korean Utility Model Registration No. 20-0248112, The driving device of the baby carriage can not be mounted or dismounted, so that it can not be used for various kinds of feeding devices. When driving without power, there is a problem that it is inconvenient to use due to its heavy weight.
