[0032] During flight, aircraft often need to collect relevant information in real time, such as images and videos along the route, due to operational requirements. Therefore, an electro-optical pod is usually fixed to the bottom of the aircraft fuselage.

[0033] In related technologies, the rotation shaft system of the optoelectronic pod is mostly a rigid connection, which requires the design of corresponding connection structures or parts, resulting in high costs. Moreover, the rotation shaft system mostly runs directly through the entire pod, greatly increasing the space occupied, and thus increasing the size and weight of the optoelectronic pod, which is not conducive to miniaturization and lightweighting.

[0034] Therefore, this utility model proposes a rigidly connected two-axis four-frame structure.

[0047] It should be noted that in order to prevent the first shaft body 33 from being separated from the first frame 10 and the second frame 20, the first shaft body 33 is directly fixedly connected with the second frame 20 after penetrating the first frame 10.

[0048] It can be understood that the first shaft body 33 is provided with a thread on one end, and the second frame 20 is provided with a connecting hole matched with the first shaft body 33, the connecting hole is provided with a thread, and the threaded end of the first shaft body 33 is inserted into the connecting hole, so as to realize the fixed connection with the second frame 20.

[0056] It can be understood that the bottom cover 34 is attached to the first frame 10 and limits the first shaft body 33 to the first frame 10, and the first shaft body 33 is limited by the bottom cover 34, so as to avoid the first shaft body 33 from moving away from the first frame 10.

[0057] Preferably, the bottom cover 34 is connected to the side of the first frame 10 away from the second frame 20 by a plurality of connecting members.

[0058] It can be understood that the bottom cover 34 is detachably connected to the first frame 10, so as to provide fixed limitation for the first shaft body 33 and ensure the stability of the rotation between the second frame 20 and the first frame 10.

[0059] It should be noted that the connecting member is a screw, which penetrates the bottom cover 34 and is connected to the first frame 10.

[0060] In an embodiment, the second frame 20 is provided with a mounting cavity 21 away from the first shaft system 30, and the second shaft system 40 is partially rotatably arranged in the mounting cavity 21 and fixedly connected to the first frame 10.

[0061] In order to install the first shaft system 30 and achieve rigid connection between the first frame 10 and the second frame 20, a mounting cavity 21 is arranged at one end of the second frame 20 away from the first shaft system 30, and the mounting cavity 21 is arranged towards the first frame 10.

[0062] It can be understood that the second shaft system 40 penetrates the second shaft system 40 and is rotatably connected to the second frame 20, and the second shaft system 40 is partially fixedly connected to the first frame 10, so as to achieve rigid connection between the first frame 10 and the second frame 20.

[0064] The second shaft body 45 is located on the side of the second frame 20 away from the motor seat 41, the second shaft body 45 penetrates the second frame 20 and is connected to the extension, so as to limit the motor seat 41 to the second frame 20.

[0065] AsFigure 3 As shown in the figure, the extension of the motor base 41 extends into the mounting cavity 21, and the extension is connected to the second frame 20 through the second bearing 44.

[0066] It can be understood that the second frame 20 rotates around the extension during rotation, thereby reducing the cost of the connecting assembly and improving the mounting efficiency of the pod by reducing the number of parts.

[0067] As shown in the figure, Figure 3 As shown in the figure, one end of the second shaft body 45 penetrates the second frame 20 and extends into the extension, and the second shaft body 45 is fixedly connected with the extension, thereby limiting the motor base 41 and the extension on the second frame 20.

[0068] It can be understood that the second shaft body 45 rotates around the extension and the second shaft body 45, and the motor base 41, the extension, and the second shaft body 45 relatively limit the first frame 10 and the second frame 20, thereby ensuring the stability of the rotation of the second frame 20 in the first frame 10 and avoiding interference between the rotation of the second frame 20 and the first frame 10.

[0071] It can be understood that the second shaft body 45 and the extension are both connected to one end of the second frame 20, and the first shaft body 33 is connected to the other end of the second frame 20, so that the first shaft body 33 cooperates with the extension to facilitate the rotation of the second frame 20.

[0072] Moreover, since the first shaft body 33 and the extension are both located at two opposite ends of the second frame 20, the shafting is directly arranged in the second frame 20 to reduce the available space inside the second frame 20, thereby making the internal space structure of the second frame 20 more compact and facilitating the reduction of the volume of the pod.

[0077] Further, in order to avoid the second bearing 44 from driving the bearing limiting portion 43 to move synchronously during the movement, thereby affecting the stability of the operation of the second frame 20, a limiting portion is arranged in the mounting cavity 21, and when the bearing limiting portion 43 is arranged in the mounting cavity 21, the bearing limiting portion 43 is in the same plane as the limiting portion.

[0078] It can be understood that the rotation of the bearing limiting portion 43 is limited by the limiting portion, and when the second frame 20 rotates, the bearing limiting portion 43 is driven to rotate synchronously by the limiting portion, so as to avoid the second bearing 44 from rotating synchronously with the bearing limiting portion 43.

[0079] In an embodiment, the side surface of the limiting portion is a first vertical section, the side surface of the bearing limiting portion 43 in contact with the limiting portion is a second vertical section, and the first vertical section is in contact with the second vertical section.
