[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of an emergency life-saving beacon provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the explosion structure of the emergency life-saving beacon shown; Figure 3 for Figure 1 The schematic diagram of the cross-sectional structure of the shielding cavity shown; Figure 4 for Figure 1 The circuit connection diagram of the emergency life-saving beacon is shown. An emergency life-saving beacon includes: a bottom cover 6;

[0026] A shielding cavity 5, wherein the shielding cavity 5 is disposed on the top of the bottom cover 6;

[0027] A beacon unit 1, wherein the beacon unit 1 is arranged on the inner side of the shielding cavity 5, and the connecting ends of the beacon unit 1 are respectively connected to a cable 9 and a second low-frequency cable 12, and one end of the second low-frequency cable 12 is electrically connected to the overload module 4;

[0028] An antenna 2, wherein the antenna 2 is disposed at the top of the shielding cavity 5, a connection end of the antenna 2 is connected to a radio frequency cable 10, and one end of the radio frequency cable 10 is connected to a connection end of the beacon unit 1;

[0029] A battery 3 is disposed on the inner side of the shielding cavity 5 , and an output end of the battery 3 is electrically connected to a first low-frequency cable 11 , and the first low-frequency cable 11 is electrically connected to the beacon unit 1 .

[0030] A sealing ring 7 is disposed between the bottom cover 6 and the shielding cavity 5 .

[0031] One end of the cable 9 is electrically connected to the data interface 8 .

[0032] The data interface 8 is fixedly installed inside the bottom cover 6 , and an input end of the data interface 8 is disposed at the bottom of the bottom cover 6 .

[0033] The bottom of the overload module 4 is fixedly mounted on the top of the bottom cover 6 , and the bottom of the battery 3 is also fixedly mounted on the top of the bottom cover 6 .

[0034] The beacon unit 1 is disposed on the top of the battery 3 .

[0035] The emergency life-saving beacon is mainly composed of a beacon unit 1, a battery 3, an antenna 2 and an overload module 4. The device has two start modes: overload trigger and manual trigger. When a manual start signal transmitted from the aircraft platform is received, or the emergency life-saving beacon's own overload module senses an abnormal overload, the emergency life-saving beacon can start up and transmit a distress beacon signal;

[0036] The device comes with a built-in battery 3. When the device is disconnected from the aircraft, the battery 3 will automatically power the device to ensure normal operation;

[0037] The beacon unit 1 is responsible for generating the beacon signal, the antenna 2 is responsible for transmitting the beacon signal, and when the battery 3 cannot power the device on board, it powers the beacon unit 1 and the overload module 4 of the emergency life-saving beacon. The main function of the overload module 4 is to send a trigger signal to the beacon unit 1 when it detects that the emergency life-saving beacon is subjected to an abnormally large overload from the aircraft platform, so that the beacon unit 1 starts working and transmits a beacon distress signal;

[0038] The antenna 2 is arranged at the top layer of the device, and is connected to the shielding cavity 5 by screws. The shielding cavity 5 and the bottom cover 6 are sealed by a sealing ring 7 to form an independent cavity, so as to ensure that the radio device in the cavity is electromagnetically isolated from the antenna 2. In this way, it is ensured that the antenna 2 will not be subject to electromagnetic interference when receiving and transmitting radio signals.

[0039] The bottom cover 6 is provided with an externally connected data interface 8, which is used by the aircraft platform to power on the beacon unit 1 and transmit control signals;

[0040] The equipment has the advantages of simple structure, light weight, good economy and strong versatility.

[0041] The working principle of an emergency life-saving beacon provided by the utility model is as follows:

[0042] The antenna 2 is cross-linked with the beacon unit 1 through the radio frequency cable 10, the overload module 4 is cross-linked with the beacon unit 1 through the low-frequency cable 12, and the battery 3 is cross-linked with the beacon unit 1 through the low-frequency cable 11. When the data interface 8 cannot provide onboard power, the battery 3 can power the beacon unit 1.

[0043] Compared with the related art, the emergency life-saving beacon provided by the utility model has the following beneficial effects:

[0044] By integrating the host and the antenna, and designing a battery 3 and an overload module 4 inside the device, the device can still work normally even if it is disconnected from the aircraft.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
