Description

Technical Field

[0001] This utility model relates to the field of aircraft equipment, and more specifically to a mounting bracket for a flight data recorder. Background Technology

[0002] The flight data recorder, also known as the black box, is used to record various parameters of an aircraft during flight, such as flight time, speed, altitude, aircraft roll, engine speed and temperature.

[0003] It is usually fixed inside the tail of the aircraft. It is usually installed on the connecting plate inside the aircraft by bolts. Because it stores important flight data, the previous operation can be understood through it when the aircraft is involved in an accident. However, the bolt fixing makes it difficult to separate from the connecting part of the aircraft later, which affects the separation effect and makes the flight data recorder prone to damage or difficulty in disassembly in the event of an accident. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a mounting bracket for a flight data recorder. It is fixed by riveting, which makes the flight data recorder firmly fixed. At the same time, it is easy to detach when subjected to impact or other problems, thus ensuring its performance.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A mounting bracket for a flight data recorder includes an aircraft stiffener frame. A horizontal insulating plate is pressed against the top surface of the lower horizontal plate of the aircraft stiffener frame. The front part of the horizontal insulating plate extends out of the front part of the lower horizontal plate. One side wall of the front part of the horizontal insulating plate is formed with an upwardly extending bent edge.

[0007] The flight data recorder is pressed against the top surface of the horizontal insulating plate, and the flight data recorder is fixed to the horizontal insulating plate and the lower horizontal plate by riveting.

[0008] A bent reinforcing plate is pressed against the bottom surface of the front part and the outer wall of the bent edge of the horizontal insulating plate.

[0009] The horizontal part of the bent reinforcing plate and the front part of the horizontal insulating plate are fixedly connected to the connecting feet of the flight data recorder by rivets.

[0010] The vertical portion of the bending reinforcement plate is tightly attached to the outer wall of the corresponding bending edge and fixed with rivets.

[0011] The outstanding effect of this utility model is:

[0012] It uses a riveting method for fixing, which makes the flight data recorder securely fixed, while also preventing it from easily falling off when subjected to impacts or other problems, thus ensuring its effectiveness. Attached Figure Description

[0019] For example, see below. Figures 1 to 6 As shown, a mounting bracket for a flight data recorder includes an aircraft stiffener frame 10. A horizontal insulating plate 20 is pressed against the top surface of the lower horizontal plate portion 11 of the aircraft stiffener frame 10. The front portion of the horizontal insulating plate 20 extends out of the front portion of the lower horizontal plate portion 11, and a side wall of the front portion of the horizontal insulating plate 20 is formed with an upwardly extending bent edge portion 21.

[0020] The top surface of the horizontal insulating plate 20 is pressed against the flight data recorder 30, which is fixed to the horizontal insulating plate 20 and the lower horizontal plate 11 by riveting.

[0021] The horizontal insulating plate 20 is fixed to the top surface of the lower horizontal plate 11 by rivets, and the head of the rivet is clamped between the head of the rivet and the top surface of the horizontal insulating plate 20 to hold the insulating gasket 1.

[0022] The head of the rivet is fitted with an insulating sleeve 2.

[0023] In the above structure, the use of an insulating sleeve 2 and an insulating gasket 1 enables the flight data recorder 30, which is mounted on the horizontal insulating plate 20, to be insulated from the aircraft stiffener frame 10.

[0024] Furthermore, a bending reinforcing plate 40 is pressed against the bottom surface of the front portion of the horizontal insulating plate 20 and the outer wall of the bent edge 21. The bending reinforcing plate 40 improves the strength of the horizontal insulating plate 20 and the bent edge 21.

[0025] Furthermore, the horizontal part of the bent reinforcing plate 40 and the front part of the horizontal insulating plate 20 are fixedly connected to the connecting foot 31 of the flight data recorder 30 by rivets. An inner insulating sleeve 3 is fixedly inserted on the inner side of the connecting through hole of the connecting foot 31, so that when the rivet is connected, it is also in an insulated state with the connecting foot 31 of the flight data recorder 30. A second insulating washer is inserted on the connecting rod of the corresponding rivet, which is clamped between the head of the rivet and the top surface of the connecting foot 31 of the flight data recorder 30. The structure of the second insulating washer and the rivet is consistent with the connection structure of the horizontal insulating plate 20 and the lower horizontal plate 11, which is omitted in the figure.

[0026] Furthermore, the vertical plate portion of the bending reinforcing plate 40 is closely attached to the outer wall of the corresponding bending edge portion 21 and fixed by rivets.

[0027] Furthermore, the vertical section of the bent reinforcing plate 40 has a waist-shaped through hole formed in the middle. The waist-shaped through hole serves to reduce weight.

[0028] Furthermore, the bending reinforcing plate 40 is an aluminum alloy plate.

[0029] In this embodiment, all components are fixed with rivets to ensure a firm connection between the horizontal insulation plate 20, the flight data recorder 30, and the aircraft stiffener frame 10. The rivet fixing also ensures that the rivets will break when subjected to impacts or other forces, making it easy for the flight data recorder 30 to detach. This prevents it from being damaged or destroyed along with the aircraft, ensuring its integrity and allowing for subsequent viewing of internal data to understand the aircraft's operational status.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
