Elevator door driving system and elector door

Abstract

The invention provides an elevator door driving system. The elevator door driving system comprises a landing door and a door driving device. The landing door comprises a hollow door shaft which comprises a first door shaft body and a second door shaft body. The door driving device comprises a motor and a mechanical transmission assembly. The motor is arranged in the first door shaft body and drives the second door shaft body through the mechanical transmission assembly. The mechanical transmission assembly comprises a driving part, a driven part and a middle part, the driving part is installed on the outer surface of the first door shaft body, the driven part is installed on the outer surface of the second door shaft body, and the middle part is connected with the driving part and the driven part. The invention further provides an elevator door adopting the elevator door driving system. By means of the elevator door driving system provided by the invention, the problem that the landing door occupies the shaft space is solved, and the advantages of simple structure, convenient operation and lower cost are achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator door drive system and an elevator door using the elevator door drive system. Background technique [0002] Household elevators generally adopt elevators without car doors and automatic door elevators. The elevators without car doors are a kind of elevators without door-opening motors, and only use the hall doors that are opened manually. However, in daily life applications, if the hall door can only be opened manually, it is difficult for people with inconvenience; although the automatic door elevator can be used by the disabled and the elderly, it also has the problem of occupying the space of the well. Since the design of the home elevator is limited by space, how to save the space occupied by the door system has high practical significance. [0003] At present, the elevator door structure of the existing automatic door elevator has the following methods: [000...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the technical problem of hoistway space occupied by the existing home elevators, the present invention provides an elevator door drive system. The elevator door drive system sets the drive motor in the door shaft of the hall door and drives the The hall door is opened horizontally, which not only solves the problem that the hall door occupies the hoistway space, but also has the advantages of simple structure, convenient operation and reduced cost
