Description

Technical Field

[0001] This utility model relates to the field of aviation equipment protection technology, and in particular to a modular avionics box. Background Technology

[0002] In existing small and medium-sized aircraft, each avionics device is independently fixed to the frame, which can easily lead to a chaotic equipment layout and hinder upgrades and replacements. When it is necessary to update a functional module of the avionics system, such as updating the image transmission equipment, the mounting bracket may need to be modified in a distributed layout, and cables and other components also need to be rearranged and adjusted, making the operation complex.

[0003] Distributed avionics systems lack shielding, making them susceptible to interference from external electromagnetic signals, leading to signal distortion and transmission interruptions. Furthermore, distributed avionics boxes rely primarily on natural convection for heat dissipation. When the avionics equipment is powerful or the ambient temperature is high, this ineffective heat dissipation can result in excessively high internal temperatures.

[0004] Existing solutions lack dedicated wiring channels, and exposed avionics equipment layouts easily lead to tangled wires and cables. This not only affects aesthetics but also makes it difficult to quickly locate problematic lines during inspections or troubleshooting, increasing maintenance time and complexity. Messy wiring also increases the risk of electromagnetic coupling, raising the likelihood of interference between different lines and impacting the performance of the avionics system.

[0005] While some avionics equipment has independent enclosures, it's difficult for them to simultaneously provide dustproof, moisture-proof, and corrosion-proof capabilities. Equipping each device with such protective enclosures would significantly increase cost and weight. Furthermore, the long-term exposure of the equipment's connectors makes them susceptible to damage, such as corrosion, moisture, and mold. This also increases the risk of electric shock to personnel and short circuits in the equipment, making maintenance operations prone to accidents. Moreover, unauthorized access allows avionics equipment to be easily tampered with or damaged, jeopardizing flight information and control safety. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1 to 7 A modular avionics box includes an equipment box 1 and an equipment mounting plate 2. The equipment box 1 consists of an insulated housing 3 and a side cover 4. The insulated housing 3 has an opening on its front side for the side cover 4 to be fastened. One end of the equipment mounting plate 2 is fixedly connected to the side wall of the side cover 4. The side wall of the insulated housing 3 has ventilation / sealing heat dissipation openings 30. Avionics equipment 5 is replaceably arranged on the equipment mounting plate 2. The side cover 4 has openings for the wiring harnesses of the avionics equipment 5 to pass through. This utility model, by designing an independent equipment box 1 and modularly mounting the avionics equipment 5 on the equipment mounting plate 2, creates a heat-insulating, waterproof, moisture-proof, and anti-aging environment for the avionics equipment 5. The insulated housing 3 and the side cover 4 are connected by spring-loaded latches for opening and closing, allowing for quick maintenance of all avionics equipment 5 after opening the housing.

[0025] The two equipment mounting plates 2 are arranged in parallel on the side wall of the side cover plate 4, and the two equipment mounting plates 2 are connected by several fixing columns 20.

[0026] To further stabilize the installation status of the equipment mounting plate 2, a sliding groove 31 is provided on the inner wall of the heat insulation box 3, and the two sides of the equipment mounting plate 2 rest against the heat insulation box 3 along the sliding groove 31.

[0027] The heat-insulating enclosure 3 has an air outlet 32 ​​on both its left and right sides, and an air inlet 33 at its bottom. The airflow direction is from the bottom of the avionics equipment 5 to the sides, which not only prevents dust accumulation on the surface of the avionics equipment 5, but also removes dust from the avionics equipment 5, maintaining stable operation of the equipment. If further improvement in heat dissipation inside the enclosure is required, fans can be installed on the air inlet 33 and the air outlet 32.

[0028] The equipment enclosure 1 is made of thermal insulation foam. This thermal insulation foam is flame-retardant. Foam with aluminum foil can also be used as the enclosure material for electromagnetic shielding. Figure 6 As shown, the equipment box 1 can also be made of metal. The figure shows stainless steel, in which case the wall thickness of the equipment box is thinner.

[0029] For aircraft used in extremely cold conditions, heating elements 21 can also be installed at the bottom of the equipment mounting plate 2.

[0030] Several mounting posts 34 are also provided on the bottom of the heat insulation box 3. The mounting posts 34 facilitate the installation of the heat insulation box 3.
