| 英文摘要: |
| In view of the difficulties of people with disabilities in the lower limbs and the inconvenience of living，a multi functional wheelchair wheel leg
composite chassis mechanism was designed with the goal of adjusting the overall height position of the wheelchair and completing the outdoor obstacle in this paper. Through the kinematic
analysis，the height transformation range of the chassis mechanism and the coupling relationship between the two driving pushers were obtained. Static analysis of key components in the
chassis mechanism and simulation optimization of key components were carried out to ensure the overall stability of the chassis mechanism in the adjustment height. The prototype
experiment verifies that the wheel leg composite chassis mechanism can achieve height adjustment stably and effectively. The design can adjust the center of gravity and posture of the
body，and can also meet the needs of outdoor obstacles. |
