AI Technical Summary

Problems solved by technology

In order to solve the problem of autonomous boarding and disembarkation for people with lower limb disabilities, wedge-shaped ramps are currently used for manual lifting, parallelogram swing arm lifting, door side flip plate flipping and lifting, frame chassis slotting and sinking, independent electric lifting and translation into the car The interior and exterior doors are moved up and down by turning the lever, and the wheelchair is moved to the roof. These measures can realize the wheelchairs for people with lower limb disabilities into the car. For the normal use of the device, it is necessary to modify the structure of the car body or the layout of the doors, etc., which is insufficient to modify the structure of the original car, especially the positioning and effective fixation of the wheelchair cannot be guaranteed.

Patent No. CN103754272A discloses a special car getting on and off device for persons with disabilities with lower limbs.
