Abstract

Disclosed is a personal mobility device including a towing module configured to allow various types of towed modules to be selectively connected and towed, and a connection device configured to connect the towing module and the towed modules. The connection device includes a connection member extending rearward from the towing module, a connection shaft having an upper side rotatably supported on the connection member and a lower side coupled to a shaft coupling hole formed on a connection frame of the towed module, and a locking device provided on the connection frame to lock the connection shaft.

First claim

What is claimed is:

1. A personal mobility device comprising:
a towing module configured to allow one of various types of towed modules to be selectively connected and towed; and
a connection device configured to connect the towing module and the towed modules,
wherein the connection device comprises:
a connection member extending rearward from the towing module;
a connection shaft having an upper side rotatably supported on the connection member and a lower side coupled to a shaft coupling hole formed on a connection frame of the towed module; and
a locking device provided on the connection frame to lock the connection shaft; and wherein the connection device further comprises a lifting device installed on an upper side of the connection member to rotatably support the connection shaft and configured to move the connection shaft in a vertical direction to adjust a height of the connection frame.

2. The personal mobility device according to claim 1 , wherein
the towing module comprises:
a driving wheel;
a driving motor provided to drive the driving wheel; and
a battery provided to supply power to the driving motor.

3. The personal mobility device according to claim 1 , wherein
the lifting device comprises:
an outer housing fixed to the upper side of the connection member;
a shaft support member installed in the outer housing to be movable up and down and rotatably supporting the upper portion of the connection shaft; and
a lifting driving unit installed on the outer housing to move the shaft support member in the vertical direction.

4. The personal mobility device according to claim 3 , wherein
the lifting device further comprises a bearing installed between an outer surface of the connection shaft and an inner surface of the shaft support member.

5. The personal mobility device comprising:
a towing module configured to allow one of various types of towed modules to be selectively connected and towed; and
a connection device configured to connect the towing module and the towed modules,
wherein the connection device comprises:
a connection member extending rearward from the towing module;
a connection shaft having an upper side rotatably supported on the connection member and a lower side coupled to a shaft coupling hole formed on a connection frame of the towed module;
a locking device provided on the connection frame to lock the connection shaft; and
the locking device comprises:
a locking pin provided on the connection frame to move forward and backward in a direction of intersecting the connection shaft and fastened to a pin coupling hole of the connection shaft entering the shaft coupling hole; and
a locking driving unit provided to move the locking pin forward and backward.

6. The personal mobility device according to claim 5 , wherein
the locking driving unit comprises:
a screw shaft screwed to the locking pin to move the locking pin forward and backward by rotation; and
a motor mounted on the connection frame to rotate the screw shaft.

7. A personal mobility device comprising:
a towing module configured to allow one of various types of towed modules to be selectively connected and towed; and
a connection device configured to connect the towing module and the towed modules;
wherein the connection device comprises:
a connection member extending rearward from the towing module;
a connection shaft having an upper side rotatably supported on the connection member and a lower side coupled to a shaft coupling hole formed on a connection frame of the towed module;
a locking device provided on the connection frame to lock the connection shaft; and
wherein the connection shaft comprises a first outer diameter part and a second outer diameter part having different outer diameters formed on an outer surface of the connection shaft to be selectively connected depending on a size of a shaft coupling hole of the connection frame.
