2、gn, Manufacturing and AutomationStudent: Yaozu Zhang Instructor: Li HouAbstract:Electric powered wheelchair is a wheeled vehicle which takes storage battery as power and motor as driving with characteristics of labor sa

3、ving, easy operation, stable speed, free-pollution and low noise. It very benefits for the people with lower or upper extremely impairment, the old or the valetudinarians. To these people, Electric powered wheelchair is

4、their primary and ideal means of mobility. However, the price of the electric wheelchair on the market is also generally high. It’s hard to popularize among the old people and the disabled. The design and development of

5、a kind low-cost electric powered wheelchair will certainly have a broad market space. On the basis of the study of the electric powered wheelchair mechanical system at home and abroad, use the modern mechanical design th

6、eory and method, analyse and re-design the drive mode. Optimize the body frame structure. And add some necessary accessibility devices. Use computer aided design software to build a three-dimensional model of the wheelch

7、air and it’s components. A scheme with rear wheel drive, differential steering has been proposed. Two motors control the rotation direction and rotation speed of the two rear wheels respectively to make the running speed

8、 and driving directions of the wheelchair change. This scheme has the advantage of change direction flexibly. Based on this driving scheme, speed reduction unit and other transmissions matched with the scheme have been d

9、esigned. A simplified type of body frame has been used in the body design.The structure of this type of body frame strong, stable, simple and light. And can be dismantled easily. This design of the electric wheelchair’s

10、mechanical systems has lay a certain foundation for the new type low-cost electric powered wheelchair, and has given a reference scheme about drive mode and body frame structure.Key Words：Electric powered wheelchair, Des
