Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a serial airborne communication equipment chassis. Background Technology

[0002] Airborne communication equipment refers to electronic devices used for communication on aircraft. It mainly includes aircraft radios and intercoms. Aircraft radios are used for communication between the aircraft and the ground, between the aircraft and ships, and between aircraft; intercoms are used by flight crew to communicate with each other or to connect to the aircraft radio for external communication. Some intercoms also allow communication with ground personnel before takeoff via jacks located on the outside of the aircraft. Compared to ground equipment, airborne communication equipment operates in harsher environments, requiring better shock and vibration resistance; the ability to withstand drastic changes in temperature, humidity, and air pressure; high reliability; small size; and light weight. Aircraft radio antennas must also possess sufficient structural strength and good aerodynamic performance.

[0003] Existing airborne communication equipment has a complex structure, and its internal components need to be installed separately, which greatly increases assembly time and reduces processing efficiency. Furthermore, when used in high-vibration environments, damaged internal components need to be completely disassembled for repair or replacement. Utility Model Content

[0039] The front panel assembly 1 is connected to a positioning mechanism 8 for positioning the chassis.

[0040] The advantages of adopting the above technical solution are that the modular design allows for quick installation of the entire chassis through the screw 7, making assembly and maintenance convenient. During maintenance, only the faulty module needs to be replaced.

[0041] In some implementations, the front panel assembly 1 includes: a panel 11, a rear panel housing 12, a grounding terminal 13, and a plurality of interfaces 14. The grounding terminal 13 and the interfaces 14 are mounted on the panel 11. A heat sink 15 is provided on the side of the rear panel housing 12. The interfaces 14 include a plurality of control interfaces, power interfaces, and radio frequency interfaces.

The locking device cooperates with the latch 16 to lock the entire chassis, making it fixed and easy to disassemble.

[0044] Furthermore, a mounting plate is provided on the fixing plate 81. The fixing plate 81 is horizontally positioned, and a shock absorber is provided on its lower side to support the entire chassis. The mounting plate is vertically positioned, and the positioning pin 82 is horizontally locked onto the fixing plate 81 (e.g., Figure 7 As shown, the locating pin 82 is locked by the nut 72 and the washer 71. The locating pin 82 has a tapered protruding end, which is inserted into the circular hole 53 on the locating block 52 for fixation.

[0045] In some embodiments, the locking device includes: a locking rod 83, a limiting block 84, and a locking block 85 (e.g., Figure 6 As shown, one end of the locking rod 83 is hinged to the fixed plate 81.
