[0031] To make the purpose, technical solution and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings in the embodiments of this application.

[0032] The installation bracket structure of an airborne device with adjustable installation angle in this application reduces the requirements for aircraft part processing, manufacturing, and component docking, and reduces the problems of long production cycle and high manufacturing cost caused by high installation requirements for certain airborne devices on the aircraft. At the same time, it provides a solution for adjusting certain airborne devices in the field.

[0033] As Figures 1 to 3 shown, the installation bracket structure of an airborne device with adjustable installation angle provided in this application includes: a rotatable installation bracket 1, a bracket base 2, a plate nut 3, a connection component, and a positioning pin 6.

[0034] The rotatable installation bracket 1 is used to carry the airborne device, and is provided with an installation interface 11 for connecting with the airborne device (not shown). A plurality of bolt through - holes are designed on the rotatable installation bracket 1, namely the first bolt through - hole 12 and the second bolt through - hole 13. Among them, the first bolt through - hole 12 is a circular hole and there is one, which is approximately located at the rotation center of the rotatable installation bracket 1, facilitating the angle adjustment of the rotatable installation bracket 1 during installation. The second bolt through - hole 13 is multiple and distributed around the first bolt through - hole 12 on the rotatable installation bracket 1. The second bolt through - hole 13 is an oblong hole, and the rotation center of the oblong hole is a circular hole. In this application, the number of the second bolt through - holes 13 is 3 - 6. For example, in the illustrated embodiment of this application, the number of the second bolt through - holes 13 is set to four.

[0035] It should be noted that the circumferential radian of the oblong hole on the rotatable installation bracket 1 is the rotatable adjustment angle range α of the rotatable installation bracket 1 relative to the bracket base 2, and this adjustment angle range α can be enlarged or reduced as needed. In addition, a number of weight - reducing holes or weight - reducing grooves can be provided on the rotatable installation bracket 1 of this application to reduce the structural weight.

[0036] The bracket base 2 is fixed on the aircraft structure (not shown) and is used to support the rotatable installation bracket 1. Among them, the bracket base 2 can be adjusted according to the shape at the installation position on the aircraft.

[0037] The bracket base 2 is provided with circular through holes 21 adapted to the multiple bolt through holes on the rotatable mounting bracket 1. The pallet nut 3 is arranged on the back side of the bracket base 2 (i.e., the side away from the rotatable mounting bracket 1) at the circular through holes 21 by riveting, and is used to cooperate with the connecting component to fixedly connect the rotatable mounting bracket 1 and the bracket base 2. In this embodiment of the present application, the number of the circular through holes 21 is five.

[0038] At least two positioning pins 6 are used to fix the installation angle between the bracket base 2 and the rotatable mounting bracket 1. The positioning pin holes for installing the positioning pins 6 are drilled on the aircraft after the installation angle between the bracket base 2 and the rotatable mounting bracket 1 is determined. In the present application, the positioning pins 6 can be pin bolts.

[0039] The connecting component includes a bolt 4 and a washer 5. After the position of the positioning pin 6 is determined and the positioning pin 6 is fixed, the connecting component composed of the bolt 4 and the washer 5 is used to firmly connect the rotatable mounting bracket 1 and the bracket base 2.

[0040] In the present application, the pallet nut 3, the bolt 4, the washer 5, and the positioning pin 6 can all be standard parts.

[0041] The installation process of the airborne equipment mounting bracket structure of the present application is as follows.

[0042] 1) First, fix the bracket base 2 to the aircraft structure, and fix the pallet nut 3 on the back side of the circular through holes 21 on the bracket base 2 by riveting.

[0043] 2) Use a connecting component to pass through the first bolt through hole 12 in the middle of the rotatable mounting bracket 1 and connect it to the pallet nut 3 at the corresponding circular through hole 21 of the bracket base 2.

[0044] 3) Adjust the installation angle of the rotatable mounting bracket 1 relative to the bracket base 2 to an appropriate position, drill positioning pin holes on the rotatable mounting bracket 1 relative to the bracket base 2, and fix the installation angle between the rotatable mounting bracket 1 and the bracket base 2 through the positioning pins 6.

[0045] 4) Use four connecting components to pass through the second bolt through hole 13 and the circular hole 12 at the corresponding position of the bracket base 2, and fixedly connect the rotatable mounting bracket 1 and the bracket base 2. Finally, install the airborne equipment on the mounting interface 11 of the rotatable mounting bracket 1, and the installation of the airborne equipment is completed.

[0046] The adjustable installation angle airborne equipment mounting bracket structure of the present application can be applied to the installation of airborne equipment that needs to adjust the installation angle on various types of aircraft by adjusting the rotatable mounting bracket in the later stage, which can reduce the installation cycle and cost of the airborne equipment and improve the maintainability.

[0047] In the structure of the airborne equipment mounting bracket for adjusting the mounting angle of the present application, the bracket base and the rotatable mounting bracket are simple in structure and convenient to manufacture. Other parts can all adopt existing standard parts. The whole mounting process is simple and easy to operate, and the mounting zero position accuracy is high, which can meet the mounting requirements that the mounting error of some airborne equipment is not greater than ±0.1°.

[0048] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
