Specifically, the rotary gear 742 can be connected to the drive motor 735 by an axis. That is, the rotation gear 742 can be rotated by the operation of the drive motor 735.

The pinion gear 744 can engage with the rotary gear 742. At this time, three pinion gears 744 are provided and can be meshed with the rotary gear in a triangular arrangement. That is, when the rotary gear 742 rotates, the three pinion gears 744 form an equal interval and can rotate along the rotary gear 742.

The raceway 746 can be engaged with the three pinion gears 744. Also, the orbit 746 may be fixed to the pinion gear 744 so as to enclose a part of both sides of the three pinion gears 744, although it is not shown in the figure.

That is, the track 746 is formed in a triangular structure along three pinion gears 744 formed in a triangular arrangement and can be fixed to both sides of the pinion gear 744, An orbit 746 fixed to the gear 744 may also work together.

The multi-wheel housing 748 can be formed on both sides of the multi-wheel 740 such that the pinion gear 744 is not disengaged. At this time, the multi-axle housing 748 may be formed to surround three pinion gears 744 by a predetermined amount so as not to interfere with the track 746. That is, the multi-axle housing 748 is also triangular in structure, and does not interfere with the raceway 746, and the rotary gear 742 can be built in.

In addition, the multi-wheel unit 700 may be manually operated in conjunction with the wireless module unit 300, or may be automatically operated if it is determined that the passive wheelchair 100 is stopped by a step or a guide bar.

Wheelchair according to the embodiment of the present invention is advantageous in that it can be easily used without restriction in any terrain through the multi-wheel unit 700.

As described above, the smart electric double-wheel chair according to the embodiment of the present invention can be mounted with an electric driving module driven to rotate the wheel by electric power, It has the advantage of minimizing the turning radius because it is mounted on the main wheel axis which is installed inside the main wheel when it is mounted, and it is possible to attach and detach the wireless module part which can control smart wheelchair with smart operation regardless of its position. .

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
