Description

Technical Field

[0001] The invention relates to the technical field of aviation equipment protection, in particular to a modular avionics box. Background Art

[0002] In existing small and medium-sized aircraft, each avionics device is independently fixed to the frame, which easily leads to a chaotic equipment layout and is not conducive to upgrading and replacement. When a functional module of the avionics system needs to be updated, such as updating the image transmission device, the installation frame may need to be modified in a decentralized layout, and the cables also need to be re-arranged and adjusted, which is complicated.

[0003] Distributed avionics equipment lacks a shielding layer, and external electromagnetic signals can easily interfere with internal circuit communications, causing signal distortion and transmission interruption. Distributed avionics boxes mainly rely on natural convection for heat dissipation. When the power of the avionics equipment is high or the ambient temperature is high, the heat cannot be effectively dissipated, resulting in excessive temperature inside the box.

[0004] Existing solutions lack dedicated wiring channels, and the exposed layout of avionics equipment easily leads to entanglement of wires and cables, which not only affects the appearance, but also makes it difficult to quickly locate the problem line when checking the line or troubleshooting, increasing maintenance time and difficulty. Messy wiring also increases the risk of electromagnetic coupling, making it more likely that different lines will interfere with each other, affecting the performance of the avionics system.

[0005] Although some avionics equipment has independent packaging shells, it is difficult to have dustproof, moisture-proof, anti-corrosion and other capabilities. If each device is equipped with these protective shells, it will increase a lot of cost and weight. In addition, the connectors of the equipment are exposed to the outside for a long time, which can easily cause damage to the connectors, such as corrosion, moisture and mildew. On the other hand, it will increase the risk of electric shock and equipment short circuit, and accidents are easy to cause during maintenance. In addition, unauthorized contact can easily cause tampering and damage to avionics equipment, which will endanger flight information and control safety. Summary of the invention

[0006] In order to solve the above problems, an object of the present invention is to provide a modular avionics box for centrally installing avionics equipment and improving the safety of the avionics equipment.

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

[0024] See also Figures 1 to 7 A modular avionics box includes an equipment box 1 and an equipment mounting plate 2. The equipment box 1 is composed of a heat-insulating box body 3 and a side cover plate 4. The front side of the heat-insulating box body 3 is provided with an opening for the side cover plate 4 to be buckled. One end of the equipment mounting plate 2 is fixedly connected to the side wall of the side cover plate 4. The side wall of the heat-insulating box body 3 is provided with a ventilated / closed heat dissipation opening 30. The avionics equipment 5 can be replaceably arranged on the equipment mounting plate 2. The side cover plate 4 is provided with an opening for the wiring harness of the avionics equipment 5 to pass through. The present invention creates a heat-insulating, waterproof, moisture-proof and anti-aging environment for the avionics equipment 5 by designing an independent equipment box 1 and modularly arranging the avionics equipment 5 on the equipment mounting plate 2. The heat-insulating box body 3 and the side cover plate 4 are opened and closed with spring buckles. After the box body is opened, all avionics equipment 5 can be quickly maintained.

[0027] The heat-insulating box 3 has an air outlet 32 ​​on both sides, and an air inlet 33 at the bottom. The airflow direction is from the bottom to the side of the avionics equipment 5, which can prevent dust from accumulating on the surface of the avionics equipment 5 and remove the dust on the avionics equipment 5 to maintain the stable operation of the equipment. If it is necessary to further improve the heat dissipation inside the box, fans can be installed on the air inlet 33 and the air outlet 32.

Foam with aluminum foil can also be used as a box material for electromagnetic shielding. Figure 6 As shown, the equipment box 1 can also be made of metal. In the figure, stainless steel is used. In this case, the wall thickness of the equipment box is thinner.
