Description

Technical Field

[0001] This utility model relates to the field of shielding devices, and more particularly to electromagnetic interference shielding devices for take-off and landing aircraft. Background Technology

[0002] Electromagnetic interference shielding devices for take-off and landing aircraft are designed to protect the electronic equipment and devices inside the aircraft from external electromagnetic interference. With the development of modern aircraft technology, the complexity and integration of electronic equipment are constantly increasing, and these devices are becoming increasingly sensitive to the electromagnetic environment during flight. Therefore, it is particularly important to research and develop effective electromagnetic interference shielding devices.

[0003] Existing electromagnetic interference shielding devices typically consist of the following main components: shielding material: the core of the shielding device is a material with good conductivity and magnetic permeability, which can effectively reflect or absorb electromagnetic waves; grounding device: the shielding device usually needs to be in contact with the ground to form a current loop, thereby realizing the absorption and release of electromagnetic waves. Grounding can effectively enhance the shielding effect and prevent the shielding layer from generating reflected waves; structural design: the design of the shielding structure needs to be adjusted according to the equipment to be protected.

[0004] Traditional electromagnetic interference shielding devices operate at full power output and continue working even without electromagnetic interference. Over time, this causes internal electronic components to overheat, reducing their lifespan and significantly increasing safety risks. Therefore, an electromagnetic interference shielding device for take-off and landing aircraft is proposed to address these issues. Utility Model Content

After long-term use, the filter plate 14 can be rotated, which drives the sliding block 15 to rotate, and can be removed from the inner wall groove of the limiting shell 13 for cleaning or replacement.
