<p>The present invention relates to a mobile device for maintaining on-board posture balance comprising: a main body having a seat part where a user can sit; front arms extended forward from both sides of the main body to be positioned on the ground, and installed to be longitudinally rotated from the main body by a tilting motor; front wheels installed in the end of the front arms to be rotated, and rotated to be driven by a drive motor; rear arms extended backward from both sides of the main body to be positioned on the ground, and installed to be longitudinally rotated from the main body by a tilting motor; rear wheels installed in the end of the rear arms to be rotated, and rotated to be driven by a drive motor; steer motors for supplying driving force so that one or both of the front and rear wheels can be rotated to change the directions; a battery installed to supply power to the tilting motors, the drive motors, and the steer motors; and a control part for controlling the tilting motors, the drive motors, and the steer motors based on the operation signals of an operation part. The present invention can prevent the backward or lateral inclination of the user when a wheel chair moves on forwardly or laterally inclined places, can pass sills, and can make the user drive conveniently and stably.</p> |
