AI Technical Summary
The movable legs of existing mobility aids can easily cause obstacles when users get on and off the vehicle, affecting riding comfort. The movable legs that turn left and right cannot be fixed, and the movable legs that flip up and down can be higher than the seat or touch the legs.
By installing elastic limiters on the mobility aid, the rotation angle between the movable leg swivel and the frame is limited, and the foot pedal tubes are positioned in front of or to the side of the frame to avoid interfering with the user's legs.
This design achieves the goal of avoiding obstruction of getting on and off the vehicle by moving legs without affecting the user's pedaling, thus improving riding comfort.
