[0003] The installation structure of key components such as intelligent obstacle avoidance devices of low-altitude aircraft is crucial for the stability and maintenance convenience of the aircraft. The existing installation method mostly adopts traditional bolt fixed connection. This method is relatively stable during installation and can ensure the reliability of components such as intelligent obstacle avoidance devices during the operation of the aircraft. However, in actual use, when the components such as intelligent obstacle avoidance devices of low-altitude aircraft need to be maintained, the disadvantages of the traditional installation method gradually appear.

[0009] A plurality of cavities are provided with circular openings for the insertion of mounting screws;

[0010] Two groups of half shaft sleeves are slidingly connected in the cavities, and the two groups of half shaft sleeves can be combined into a complete shaft sleeve, and the mounting screws are threadedly connected in the internal threads of the shaft sleeve;

[0011] A spring member is connected in the cavity, and the other end of the spring member is connected with the half shaft sleeve;

[0012] A pull rope is connected to the half shaft sleeve, and one end of the pull rope away from the half shaft sleeve penetrates the mounting plate, and pulling the pull rope can make the two groups of half shaft sleeves move away from each other.

[0013] Preferably, a groove is formed in the side of the mounting plate, and the penetrating end of the pull rope is located in the groove.

[0014] Preferably, a connecting plate is slidably connected in the groove, and the penetrating end of the pull rope is fixedly connected to the connecting plate.

[0015] Preferably, a pull rod is fixedly connected to the connecting plate.

[0016] Preferably, a plurality of jack plugs are arranged on the mounting plate, and a supporting leg is inserted into the jack plug.

[0017] The intelligent obstacle avoidance device for low-altitude aircraft comprises a mounting assembly, and further comprises:

[0018] A plurality of laser radar sensors are mounted on the end of the mounting plate away from the supporting leg.

[0019] Compared with the prior art, the mounting assembly and the intelligent obstacle avoidance device for low-altitude aircraft have the following beneficial effects:

[0020] In actual application, when related components need to be disassembled and maintained, only the pull rope needs to be pulled quickly, and the two groups of half shaft sleeves that are originally closely attached can be quickly separated. The separation of the half shaft sleeves releases the connection relationship between the mounting bolt and the mounting plate. In this way, the mounting plate can be quickly disassembled from the low-altitude aircraft. This design effectively simplifies the disassembly process and greatly improves the convenience of maintenance. BRIEF DESCRIPTION OF DRAWINGS
