Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically an aircraft cabin door alarm device based on an inductive sensor. Background Technology

[0002] In recent years, incidents of accidental activation of aircraft emergency exits have become increasingly common. Passengers opening emergency exits out of curiosity or by mistake not only cause flight delays but can also trigger panic in the cabin and even jeopardize flight safety. However, current aircraft door safety designs largely rely on mechanical locks or simple warning signs, lacking real-time monitoring and early warning capabilities, making it difficult to effectively prevent accidental activation. Furthermore, some alarm devices are bulky, heavy, or require external power, making them difficult to install and use in confined spaces or areas without power.

[0003] Therefore, there is an urgent need for a lightweight, independently powered device with a rapid alarm function to promptly alert passengers in the early stages of accidental activation, while also prompting the crew to take swift action to prevent dangerous behavior from escalating. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an aircraft cabin door alarm device based on an inductive sensor, aiming to effectively prevent accidental activation of aircraft cabin doors and ensure flight safety through real-time monitoring and rapid alarm.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] An aircraft door alarm device based on an inductive sensor includes a battery compartment, an inductive switch, an LED strobe light, and a buzzer, wherein the battery compartment, the inductive switch, the LED strobe light, and the buzzer are connected in series.

[0007] The inductive switch includes a human body sensing probe and a control component. The human body sensing probe is used to sense the human body and send a signal to the control component. The control component controls the opening and closing of the circuit based on the sensing signal.

[0008] Optionally, the battery compartment is equipped with a switch and a magnetic suction part at the bottom.

[0009] Optionally, the LED strobe light includes a base plate, on which a plurality of light-emitting units are provided.

[0010] Optionally, the induction switch and the LED strobe light are integrated and combined to form an induction light.

[0011] Optionally, the alarm device has a housing, and the battery compartment, induction switch, LED strobe light and buzzer are all located on the housing;

[0012] The LED strobe light and buzzer are located on the front side of the housing, and the sensor switch is located at the lower front of the housing.

[0013] Optionally, the inductive switch has rotating shafts on both sides, and is rotatably connected to the housing through the rotating shafts.

[0014] Optionally, the rear of the housing is provided with a battery compartment, a switch is provided on one side of the battery compartment, and a magnetic suction part is provided above the battery compartment at the rear of the housing.

[0015] The advantages of this utility model are:

[0016] This invention uses a human body sensor to monitor the area near the cabin door handle in real time. Once human activity is detected, it immediately triggers an audible and visual alarm, activating an LED strobe light and a buzzer. This combined audible and visual alarm system promptly alerts passengers who accidentally touch the door to stop their inappropriate behavior and quickly notifies the crew, effectively preventing accidental opening of emergency exits and ensuring the normal operation of the flight and the safety of passengers.

[0017] This utility model uses an independent power supply from the battery compartment, eliminating the need for an external power source. It is small and lightweight, making it easy to install in the confined space of an aircraft cabin door. The magnetic part can be attached to the inner wall of the cabin door, making installation and removal convenient and facilitating battery replacement and routine maintenance.

[0018] This invention is applicable not only to monitoring and alarming aircraft doors, but also to various other scenarios. For example, it can be used in areas that pose a danger to children, areas where electricity is present and should not be touched, for security of doors and windows on lower floors, and in restricted areas. This invention features a simple structure, low manufacturing cost, lightweight design, and easy installation, making it widely applicable in various monitoring and alarm scenarios.
