Abstract：Using Autodesk Inventor software，we gets a wheel car with novel structure，simple and reliable operation and strong practicability.In the elderly alone in the home life，exercise and other occasions，the car plays a fall prevention，help walking，guidance and follow functions.Wheel car is mainly composed of four modules：drived，vehicle variable frame，steering and front and rear operation.By adjusting the variable posture mechanism，various working modes can be set，such as climbing obstacle（suitable for entering and leaving balcony，toilet and other indoor places with slope and small steps），exercise walking following，flat road seat and spot turning （turning radius is almost "zero"）.It can be switched on demand to meet the use needs of the elderly in different scenes at home.The research of this wheel car has obtained 1 national authorized patent，1 patent is in application，and wins 1 second prize of National College Students Mechanical Design Competition and 1 second prize of Zhejiang College Students Mechanical Innovation Design Competition.
