At this time, the user can rotate the retractable armrest 105 to fold it up. Because a damping plate is installed at the rotation point between the retractable armrest 105 and the vehicle body 100, the armrest can rotate smoothly and slowly, avoiding accidental injury to the user. In this way, there is no obstruction on one side of the wheelchair, and the user can directly move their body onto the seat cushion 101 by hand. With the help of an assistant, the patient's legs are gently moved onto the leg pad 102. Once the patient is comfortably seated on the seat cushion 101, the servo motor is driven again, and the leg pad 102 will retract to its original position, completing the boarding process. In addition, the interactive screen 109 can also be used for practical functions such as external navigation, providing users with a more convenient and intelligent user experience.
[0025] In this embodiment, a backrest cushion 200, fixedly connected to the vehicle body 100, is added to the upper end of the seat cushion 101.
