Design background In order to meet the needs of mobility and rehabilitation, wheelchairs and walking aids are two necessary assistants for people with mobility difficulties, and carrying them has become a major problem . Design concept The wheelchair and the walker are integrated, so that the user can change it into another appearance for use with simple operation, and optimize the whole use process and function. Wheelchair Mode Put the seat cushion and foot pedal part down towards yourself. At this time, the left and right buckle rings will be triggered to open the frame with elastic spring. The user only needs to sit on the seat cushion, hold the handles on both sides of the wheel, push and pull them back and forth, and press the yellow part on the handle when the brake is needed. It's an independently operated product, but if necessary, someone can help push it in the rear. In addition, there is a small groove for hanging belt, which makes the user more convenient. Walker Mode When the seat cushion and foot pedal are folded up, and the blue collar of the handle part is pulled up to lock the brake, it becomes a walker. The front two feet are small wheels, and the rear two feet are fixed big wheels. When walking, you don't need to lift too much strength to walk smoothly. There is a mechanism that can adjust the height near the wheel, which can adjust the height appropriately. The handle part is buffered by silicon glue, so that the user can be more comfortable when supporting
