Description
technical field [0001] The invention relates to the technical field of elevators and their components, in particular to an audible and visual alarm device. Background technique [0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped pod, which is used for transporting people or carrying goods in multi-storey buildings. At present, the standard of the prior art mentions that when the car is running in the elevator bypass state, the auditory signal on the car and the flashing light on the bottom of the car should play a corresponding role, and the auditory signal at the lower part of the car should not be less than 1m. 55db. However, in the prior art, the buzzer and the flashing light are mostly installed at the bottom of the elevator, which has a low product protection level and is time-consuming and labor-intensive to install. [0003] Chinese patent CN205802708U discloses an acousto-optic alarm device for an elevator and an elev...
