AI Technical Summary
Technical Problem
In existing elevator systems, the safety brake actuator is prone to reliability degradation due to foreign objects entering the gap, affecting the effectiveness of emergency braking.
Method used
Introducing object deflection arrangements, such as magnets or structural barriers, into the safety brake actuator prevents foreign objects from entering the gap and accommodates the lateral movement of the guide rail and safety brake by movable or resiliently biased covers or barriers, maintaining a reduced gap width.
Benefits of technology
It effectively prevents foreign objects from entering the gap, improves the reliability of the safety brake, enhances safety, ensures the reliability of the brake, and ensures that the safety brake can be reliably engaged in emergency situations.

Abstract
本发明涉及一种安全制动器致动器，具体地，一种电梯系统包括导轨、电梯轿厢、安全制动器致动器和安全制动器。安全制动器致动器和安全制动器安装到电梯轿厢，以在使用中与电梯轿厢一起沿着导轨移动。安全制动器致动器包括致动机构，该致动机构构造成在使用中致动安全制动器抵靠导轨的接合。安全制动器致动器还包括近侧表面，其中，安全制动器致动器邻近导轨安装，且近侧表面面向导轨并与导轨间隔开，以在导轨和安全制动器致动器的近侧表面之间限定间隙空隙。安全制动器致动器还包括物体转向布置，该物体转向布置相对于间隙空隙定位，以防止或阻碍异物进入间隙空隙中。
