Document Type and Number:
WIPO Patent Application WO/2021/147576
Kind Code:
A1
Abstract:
Disclosed is a draft curtain brake mechanism. The draft curtain brake mechanism comprises an electric motor shaft (1), a brake disk (2) and a brake head (3), wherein the brake disk (2) comprises a force transmission portion (21) and a friction portion (22); the electric motor shaft (1) is inserted into the force transmission portion (21) and drives the brake disk (2) to rotate; the brake head (3) is located on one side of the friction portion (22); and the brake head (3) comprises a brake electromagnetic coil (31). In a normal state, the brake disk (2) rotates along with the electric motor shaft (1), and the brake disk (2) is kept in a moving state even when not being used, so that when the brake mechanism starts under emergency conditions, the brake disk (2) will not be stuck, and the brake mechanism starts smoothly and has a high stability.
