Optoelectronic pods can be widely used in reconnaissance on land, sea, air and space, and their carriers are vehicles, ships, aircraft and satellites. The optoelectronic pod is generally installed on a detection carrier (such as a drone). When in use, when the detection carrier reaches the set position, the motor in the optoelectronic pod is controlled to rotate to control the direction of the optoelectronic equipment inside it, thereby realizing the reconnaissance or detection of the target object.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] As attached Figure 1 As shown, this example provides an internal fixing device of an optoelectronic pod body, wherein the optoelectronic pod is provided with an infrared thermal imaging module 1, a laser ranging module 2, a visible light module 3, and a pitch direct drive motor 103, and all are fixed in a pod shell, and the pod shell is composed of a pod front cover 5 and a pod rear cover 6; the internal fixing device includes an infrared module fixing plate 101, a pitch motor seat 102, an H-shaped bracket 104, a control board fixing part 105, a Y-shaped bracket 201, a positioning shaft sleeve 4, a U-shaped bracket 401, and a mainboard fixing plate 402;

[0025] In this example, the visible light module 3 is composed of two visible light modules with different focal lengths. In this example, an infrared thermal imaging module 1, a laser ranging module 2, and two visible light modules 3 are provided, and four sets of lenses form a four-light type optoelectronic pod. The position relationship of the above module components is: the infrared thermal imaging module 1 is in the middle, and the laser ranging module 2 and the visible light module are respectively on both sides of the infrared thermal imaging module 1, which can save the internal space of the optoelectronic pod;

[0026] As attached Figure 2 As shown, there is a screw hole at the rear end of the infrared thermal imaging module 1, the H-shaped bracket 104 is connected to the infrared thermal imaging module 1 by screws, and the infrared module fixing plate 101 has a circular opening, which can fix the lens part of the infrared thermal imaging module 1 to prevent shaking during imaging and deformation of the lens part due to force when the drone is suspended and flying;

[0027] The laser distance measuring module 2 has screw holes, and the laser distance measuring module 2 is fixed to the Y-shaped bracket 201 by screws. One end of the Y-shaped bracket 201 is fixedly connected to the infrared module fixing plate 101, and the other end is fixed to the H-shaped bracket 104;

[0028] The bottom of the visible light module 3 has threads, the visible light fixing piece 301 has screw holes matching the visible light module 3, the visible light fixing piece 301 is fixed on the visible light connecting bracket 302, the positioning sleeve 4 has a through hole, and the U-shaped bracket 401 is connected to the positioning sleeve 4 by screws;

[0029] As attached Figure 1The figure shows the front view of the internal structure of the pod. The components are tightly connected and the overall structure is compact, which simplifies the assembly difficulty and saves assembly procedures. At the same time, the components can be assembled separately, which simplifies the disassembly and maintenance process. The entire pod can be disassembled according to each module, so that when the pod is disassembled, some parts can be disassembled separately for maintenance and replacement. When the frequently disassembled parts are damaged, the parts can be replaced separately, which reduces the overall cost.

[0031] The optoelectronic pod in this example dissipates heat by heat conduction. The main control board is fixed on the mainboard fixing plate 402. There is a chip with relatively high heat generation on the main control board. The chip is tightly connected to the mainboard fixing plate 402. The connection position is coated with heat-conducting material. The mainboard fixing plate 402 increases the heat dissipation surface area and is fixedly connected to multiple components such as the infrared module fixing plate 101, the U-shaped bracket 401, and the control board fixing 105. The heat can be transferred to the pod front cover 5 and the pod rear cover 6. When the UAV is suspended and flying, the air circulation reduces the surface temperature of the optoelectronic pod In addition, the infrared module fixing plate 101, the H-shaped bracket 104, the control panel fixing part 105, the Y-shaped bracket 201, and the visible light fixing part 301 are fixedly connected, which is beneficial to the heat dissipation of the pod. The infrared module fixing plate 101 is provided with a plurality of through holes for fixing the structural parts connected thereto. The pitch motor seat 102 fixes the pitch direct drive motor 103, and is fixedly connected to the pod front cover 5 and the pod rear cover 6. The visible light fixing bracket 302 can fix the visible light module 3 and is fixed to the visible light connection bracket 302 by screws.

[0032] The supporting and fixing device provided in this example can be used on a three-axis rotating mechanism, and can be used on a two-axis optoelectronic pod by simply replacing the two-axis rotating mechanism.

[0033] The utility model can adapt to the spherical shell of the optoelectronic pod, and the various components are tightly connected, the overall structure is compact, the assembly difficulty is simplified, and the assembly process is saved. At the same time, it can be assembled separately, which simplifies the disassembly and maintenance process. The interior of the entire pod can be disassembled according to each module, so that when the pod is disassembled, some parts can be removed separately for maintenance and replacement. When the frequently disassembled parts are damaged, the parts can be replaced separately, which reduces the overall cost.
