Embodiment Construction

[0052] The black box protection device of the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] Such as figure 1 , Figure 2a , Figure 2b Shown is the state before the protection device is inflated, including a cubic structure frame 3, the surface of the cube is hollow, and the black box 2 is placed inside the space formed by the frame 3. In the hollows on each side of the frame 3, a strip-shaped cross-connecting mechanism 4 is provided, and the end of the connecting mechanism 4 is fixed in the frame 3. A gas generator 10 is provided at the cross joint of the connection mechanism 4. The airbag package 9 has its central part fixed in the frame 3 and passes through the connection between the frame 3 and the connecting mechanism 4 to wrap the gas generator 10 and the connecting mechanism 4 in the air chamber. After the airbag package 9 is folded, a wrapping cloth 6 is preset on the outer side thereof, and a tear line ...

Abstract

The invention provides a black box protective device, comprising a frame, a connecting mechanism, a gas generator, an air sac bag, a wrapping cloth and an inner connecting sheet, wherein the connecting mechanism is arranged at the hollow-out position of the frame, and the end part of the connecting mechanism is fixed in the frame; the gas generator is penetrated through the connecting mechanism; the central part of the air sac bag is fixed in the frame, and is penetrated through the connecting part of the frame and the connecting mechanism to wrap the frame, the gas generator and the connecting mechanism in the air chamber of the air sac bag; the wrapping cloth wraps the folded air sac bag therein, and is provided with a tearing line in advance; and the inner connecting sheet consists of a central sheet and flap sheets, wherein the flap sheet comprises a flap head, a flap root and a flap ledge. After the black box is popped from a plane, the invention provides an air sac bag protection. A plurality of soft antenna assemblies are arranged in an air sac, when the air sac bag is unfolded, one or a plurality of antennas is or are ensured upward, and thereby the reliable communication between the black box and the outside is realized.

Description

Technical field [0001] The invention relates to a protection device for precision equipment, in particular to a protection device for a black box. technical background [0002] The black box on the plane stores precision equipment such as circuit boards, recording tapes, memory chips, etc., which record various data during the flight, especially the flight parameters at the time of the accident. Therefore, the shell of the aircraft black box is required to withstand high temperature, high pressure, and long-term solution immersion. The black box is usually installed in the safest part of the rear of the aircraft, which is the part that is least vulnerable to damage in the event of a crash. An antenna is attached to the black box. When a plane crashes, it transmits signals through the antenna on the black box to communicate with the satellite so that the satellite can locate the black box. [0003] However, the outer structure of the current aircraft black box is just a rigid box,...
