[0002] With the construction of more and more high-rise buildings, elevators have become an indispensable device in existing high-rise buildings or shopping malls. Elevators provide a convenient and fast way of travel. Especially for the elderly, disabled people, children and people who carry heavy objects, elevators can make it easier for them to go up and down the stairs, reducing the consumption of physical strength and time. At the same time, the speed of elevators is getting faster and faster, which can be more efficient in production and life. Elevators can reduce the noise, dust and odor on the way to the stairs. At the same time, elevators are a comfortable, easy and pleasant way to travel. For the elderly, disabled people and families with more items, home elevators can facilitate their travel and activities and improve their quality of life. At the same time, the comfort of home elevators is also superior to stairs, which can reduce the fatigue and discomfort caused by climbing stairs. Compared with stairs, elevators have more advantages in safety and convenience. Home elevators are equipped with safety configurations such as emergency parking devices, safety doors, and anti-collision devices to ensure the safety of personnel in emergency situations. Moreover, the use of home elevators is more convenient and faster, which can improve the travel efficiency of personnel.
