Background Art

An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors. Vertical elevators have a car that runs between at least two rows of rigid guide rails that are vertical or have an inclination angle of less than 15°. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

The elevator has a large inertia when running upward, and because the elevator itself is heavy, there is a huge safety hazard when rising at high speed. Therefore, an anti-collision device is needed. Although the traditional anti-collision device has a certain anti-collision ability, it still has some shortcomings. For example, its anti-collision structure is relatively simple, and the anti-collision effect achieved by relying on a single anti-collision structure is limited. Therefore, its anti-collision effect is not ideal. Therefore, an elevator car anti-collision device is proposed to address the above problems.
