Description

Technical Field

[0001] The present invention relates to the technical field of household lifting equipment, and in particular to an automatic lifting device for household corridor reconstruction. Background Art

[0002] In the existing old residential areas with a total height of 6 floors and self-built small buildings or villas with more than two floors without elevators, it is very inconvenient for the elderly and people with mobility problems living there; the existing barrier-free lifting and moving devices are mainly installed in public places; the devices installed at home are not suitable for wheelchairs and are not convenient for single-person operation. People with mobility problems need multiple people to lift them up to the floor level when going downstairs on a daily basis; people with mobility problems can achieve the purpose of lifting up and down the floor level at home without the assistance of others during the daily use of wheelchairs. The people here include people of different ages who are already in wheelchairs and the elderly who are about to be in wheelchairs. At present, the trend of population aging is accelerating worldwide. It is very inconvenient for the elderly with mobility problems and those who are already in wheelchairs to go up and down the stairs in two- or three-story buildings or villas. The houses where the elderly live are generally old residential houses, which are not suitable for installing additional elevators. It is necessary to provide a solution for home use that allows people to go directly to the second floor or above floors in a wheelchair. No holes are opened in the floor slabs, and a lifting and moving device is installed on the basis of the original stairs without affecting normal use. The overall installation of the device should be simple and convenient, the operation should be intelligent and convenient, and the safety should be high. Summary of the invention
