[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1: Reference Figures 1-4This is the first embodiment of the present invention. This embodiment provides a shock-absorbing dual photoelectric pod gimbal structure, including a mounting frame 1. The top of the mounting frame 1 is respectively provided with a first anti-wear pad 2 and a second anti-wear pad 3. Four sets of fixing blocks 4 are fixed on the outside of the mounting frame 1. The bottom of the fixing blocks 4 is provided with a shock-absorbing component 5. The bottom of the shock-absorbing component 5 is provided with a bearing plate 6. The bottom of the bearing plate 6 is provided with a cabin 7. A thermal imaging device 9 and a camera 10 are respectively installed inside the cabin 7. A cleaning component 8 is provided inside the cabin 7.

[0022] Mounting bracket 1 is installed on the bottom of the drone. The first anti-wear pad 2 and the second anti-wear pad 3 prevent wear between the mounting bracket 1 and the drone after installation. The shock absorption component 5 reduces the vibration generated by the drone during use, reduces the impact of vibration on the optoelectronic equipment, and improves the imaging quality and detection effect. The cabin 7 achieves the effect of protecting the optoelectronic equipment. The thermal imaging device 9 and the camera 10 have the same structure and working principle as the infrared thermal imager and visible light camera in application number 201721453313.8. The thermal imaging device 9 generates thermal images by detecting the infrared radiation emitted by objects, and the camera 10 captures images in the visible light range through an optical lens. This is existing technology and will not be described in detail here. The cleaning component 8 achieves the effect of cleaning dust on the lenses of the thermal imaging device 9 and the camera 10, improving the image clarity.

[0023] The shock absorption assembly 5 includes a connecting frame 51 fixed to the bottom of the fixing block 4. The connecting frame 51 has a first guide plate 52 and a second guide plate 53 respectively. The first guide plate 52 and the second guide plate 53 are rotatably connected by a connecting rod. A damper 54 is rotatably connected to one side of the first guide plate 52, and the other end of the damper 54 is rotatably connected to one side of the second guide plate 53.

[0024] The first guide plate 52 and the second guide plate 53 are rotatably connected by a connecting rod to form a deformable structure. The damper 54 consumes the vibration energy generated by the deformation of the first guide plate 52 and the second guide plate 53 through damping, thereby reducing the impact on the photoelectric equipment and improving the imaging quality and detection effect.

[0025] The cleaning component 8 includes an air pump 81 fixed to the inner wall of the chamber 7. The air outlet of the air pump 81 is connected to an air outlet pipe 82, and the outer side of the air outlet pipe 82 is connected to multiple air outlet hoods 83.

[0026] Air pump 81 draws in gas and sprays out high-pressure airflow through air outlet pipe 82 and air outlet hood 83. The airflow is sprayed onto the lens of thermal imaging device 9 and camera 10, blowing away dust and stains attached to the window on the lens, achieving contactless cleaning. Moreover, the multiple air outlet hoods 83 are in different positions, which can be adjusted and installed according to the position of the lens of thermal imaging device 9 and camera 10.

[0027] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] Specifically, four sets of threaded sleeves 11 are fixed to the inner wall of the mounting bracket 1, and a through hole 12 is opened in the inner cavity of the mounting bracket 1.

[0029] The mounting bracket 1 can be installed at the center of the bottom of the drone using the screw sleeve 11, and can be connected to other external devices through the through hole 12.

[0030] Specifically, a connecting seat 13 is fixed to the top of the bearing plate 6, and a fixing frame 14 is fixed to the top of the connecting seat 13. One end of the first guide plate 52 and the second guide plate 53 are rotatably connected to the inner wall of the fixing frame 14.

[0031] The first guide plate 52 and the second guide plate 53 are supported by the fixing frame 14, so that the first guide plate 52 and the second guide plate 53 can rotate on the fixing frame 14, thereby improving the stability of the first guide plate 52 and the second guide plate 53.

[0032] Specifically, a guide rod 15 is rotatably connected to the inner wall of the connecting frame 51, and a guide groove 16 is provided in the inner cavity of the second guide plate 53, with the outer side of the guide rod 15 being rolledly connected to the inner wall of the guide groove 16.

[0033] The movement of the connecting frame 51 causes the guide rod 15 to roll inside the guide groove 16, applying pressure to the first guide plate 52 and the second guide plate 53. The first guide plate 52, the second guide plate 53 and the damper 54 rotate, absorbing the vibration generated by the UAV and the cabin 7. The damping effect of the damper 54 reduces the vibration energy, reduces the impact of vibration on the optoelectronic equipment, and improves the imaging quality and detection effect.

[0034] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] Specifically, a bellows 17 is fixed to the inner wall of the cabin 7, and the inner wall of the bellows 17 is connected to the air inlet of the air pump 81.

[0036] The bellows 17 provides a clean air source for the air pump 81. The bellows 17 draws in outside air through the air inlet 18, and the clean air enters the air pump 81 and is ejected through the air outlet 82.

[0037] Specifically, the inner wall of the air box 17 is provided with an air inlet 18, and a filter plate is fixed on the inner wall of the air inlet 18.

[0038] The filter plate filters the dust entering the air inlet 18, preventing dust from entering the air pump 81 and the chamber 7, thus protecting the optical equipment and the air pump 81. The filtered gas then cleans the lens of the optoelectronic equipment, improving the lens cleaning efficiency.

[0039] Specifically, a drive motor 19 is fixed to the top of the support plate 6. The output end of the drive motor 19 passes through the inner wall of the support plate 6 and is fixed to a drive block 20. The bottom of the drive block 20 is fixed to the top of the cabin 7.

[0040] The drive motor 19 drives the drive block 20 and the cabin 7 to rotate, thereby adjusting the angle of the cabin 7 and realizing the rotation function of the cabin 7 to adjust the detection angle.

[0041] During use, the mounting bracket 1 is fixed to the center of the bottom of the drone by the screw sleeve 11. The first anti-wear pad 2 and the second anti-wear pad 3 can effectively prevent wear between the mounting bracket 1 and the drone, ensuring the stability and durability of the installation. When the drone vibrates during flight, the first guide plate 52 and the second guide plate 53 are rotatably connected by the connecting rod to form a deformable structure. The moving connecting bracket 51 drives the guide rod 15 to roll in the guide groove 16, applying pressure to the guide plate and causing it to rotate with the damper 54. The damper 54 consumes vibration energy through damping. The air pump 81 draws in gas and then sprays out high-pressure airflow through the air outlet pipe 82 and air outlet hood 83. The airflow sprays onto the lenses of the thermal imaging device 9 and the camera 10, blowing away dust and dirt to achieve contactless cleaning. The filter plate filters the dust and provides a clean air source for the air pump 81. The drive motor 19 drives the drive block 20 and the cabin 7 to rotate, adjusting the angle of the cabin 7 to achieve the rotation function of the cabin 7 and adjust the detection angle.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
