AI Technical Summary

Technical Problem

In existing electric lift windows, single-motor single-side drive causes problems such as window sash tilting and jamming, and traditional dual-motor double-side drive is costly, while rigid transmission imposes strict restrictions on motor position and spatial layout.

Method used

The system employs a winding reel to drive flexible traction components at both ends. These flexible traction components are then fixed to both sides of the electric lifting window via a guide assembly. A single drive device enables synchronous transmission on both sides. Combined with a pulley and guide pulley structure, this prevents detachment and improves transmission stability.

Benefits of technology

It achieves low-cost, dual-sided synchronous transmission for electric lift windows, avoiding window sash tilting and jamming, improving operational stability and service life, reducing friction noise, and enhancing visual appeal.

Abstract

The invention discloses a driving mechanism suitable for an electric vertical sliding window, the driving mechanism comprises a winding roll and a driving device for driving the winding roll to rotate, two ends of the winding roll are respectively wound with a first flexible traction piece and a second flexible traction piece, and the winding directions of the first flexible traction piece and the second flexible traction piece are consistent. One end of the first flexible traction piece and one end of the second flexible traction piece are configured to vertically extend downwards and are used for being fixed to the two sides of the electric vertical sliding window respectively. The two flexible traction pieces wound on the same winding roll are fixed to the two sides of the electric vertical sliding window correspondingly, and after the winding roll is driven by the single driving device, the two flexible traction pieces can be synchronously loosened outwards or wound inwards to be tightened, so that double-side synchronous transmission lifting or descending of the electric vertical sliding window at low cost is achieved; the problems that a window sash inclines and is clamped due to traditional single-motor single-side driving are solved, and the problems that a dual-motor dual-driving structure is high in cost and limited in layout are solved.
