Title:
CURTAIN OPENING/CLOSING TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/021542
Kind Code:
A1
Abstract:
A curtain opening/closing transmission device, comprising a primary transmission mechanism (1), a secondary transmission mechanism (2), a reversing mechanism (3), and a transmission belt (4), wherein the primary transmission mechanism (1) is located on one side of the secondary transmission mechanism (2); the reversing mechanism (3) is provided at the end of the secondary transmission mechanism (2) close to the primary transmission mechanism (1); the transmission belt (4) is provided on the primary transmission mechanism (1) and then penetrates out of the primary transmission mechanism (1); the transmission belt (4) penetrates out of the primary transmission mechanism (1) and then is wound on the reversing mechanism (3), and after passing through the reversing mechanism (3), the transmission belt (4) penetrates into the secondary transmission mechanism (2), penetrates out of the secondary transmission mechanism (2), and penetrates into the primary transmission mechanism (1) again, so that the transmission belt (4) forms a closed loop among the primary transmission mechanism (1), the reversing mechanism (3), and the secondary transmission mechanism (2). In the curtain opening/closing transmission device, a first carrier mechanism (14) and the second carrier mechanism (23) are simultaneously driven by one transmission belt (4) to respectively slide along a primary sliding rail (12) and a secondary sliding rail (22), so that the synchronization of opening and closing of a curtain is higher.
