US 2023/0406439 A1 · PERSONAL MOBILITY DEVICE, SYSTEM FOR STEERING PERSONAL MOBILITY DEVICE, AND METHOD OF CONTROLLING PERSONAL MOBILITY DEVICE

Abstract

The present disclosure provides a personal mobility device including a personal mobility device body including a first wheel mounted at a front portion and a second wheel mounted at a rear portion with respect to a longitudinal direction of the personal mobility device body. The personal mobility device may include a steering rod that includes an operable handle, and mountable on any one of steering apparatus connectors at the front portion or the rear portion. A load cell assembly may be provided on each of the steering apparatus connectors, and each including a plurality of load cells. The personal mobility device may enable steering control using a low-cost load cell, and facilitate steering in either direction of the personal mobility device.
