AI Technical Summary
In existing wheelchairs, the self-locking pulleys are insufficient to resist the force exerted on the wheelchair during patient getting in and out of bed, which can easily lead to injury to the patient.
By installing a lifting assembly and support mechanism at the bottom of the wheelchair, and using a drive motor to raise and lower the worm gear box and lead screw, the wheelchair wheels are separated from the ground, and the support plate supports the wheelchair to prevent slippage.
During the process of getting in and out of bed, the wheelchair wheels are separated from the ground to prevent slipping and protect the patient's safety.
