With technological advancements and increasingly complex application scenarios, optoelectronic platforms need to maintain stable operation in harsh environments such as high humidity, electromagnetic interference, and vehicle-mounted vibrations. However, existing optoelectronic platforms mostly adopt an integrated design, resulting in poor airtightness and maintainability of the cabin assembly, making it difficult to meet all-weather adaptability requirements in complex environments. Especially in high humidity environments, insufficient cabin sealing performance can easily lead to moisture absorption and failure of the internal optical payload, affecting equipment stability and service life.

[0032] This embodiment provides a sealed, locked optoelectronic platform with anti-interference and modular assembly / disassembly capabilities, the structure of which is as follows: Figures 1 to 6 As shown, it includes horizontal group 1, high and low group 2, and cabin group 3.

[0033] Specifically, the horizontal assembly 1 includes a horizontal shaft system component 4, a horizontal control component 5, and an inertial measurement unit 6, designed to achieve the orientation rotation and locking functions of the photoelectric platform. An electromagnetic brake 14 is installed at the bottom of the horizontal shaft system component 4, achieving orientation locking through spring pressure and friction braking. This design is simple, low-cost, and does not affect the shaft transmission accuracy, solving the problems of complexity and low precision in traditional locking mechanisms. The horizontal shaft system component 4 and the horizontal control component 5 are connected by a stop joint and bolts, with the stop joint on the mating surface ensuring assembly accuracy and sealing. The horizontal control component 5 houses a control board, an orientation filtering module 12, and an image conversion module 13, all encased in a metal shield to effectively reduce electromagnetic radiation and meet the RE102 standard requirements in GJB151B-2013. The horizontal control component 5 and the inertial measurement unit 6 are connected by a pair of positioning pins 11, which ensure precise alignment during modular disassembly and assembly, improving maintenance efficiency. The top of the horizontal group 1 is equipped with a multi-layer boss and stop structure, which is bolted to the bottom of the high and low group 2 with a multi-layer groove and stop structure to form a multi-layer labyrinth seal structure and is filled with wide-temperature grease to enhance sealing performance and vibration resistance, thus solving the problem of seal failure under high humidity and bumpy conditions.

[0034] The elevation / lowering frame 2 includes a motor shaft end 15, an angle measuring shaft end 16, an elevation / lowering frame 17, and a manual locking pin 18, designed to achieve pitch movement and zero-position locking of the optoelectronic platform. The motor shaft end 15 is mounted on one side of the elevation / lowering frame 17, allowing axial sliding, while the angle measuring shaft end 16 is mounted on the other side as a fixed reference end to ensure the accuracy of pitch movement. The main housing 8 is first fixed to the angle measuring shaft end 16 via a stop fit, forming a multi-layer labyrinth seal structure. Then, the motor shaft end 15 is axially moved to its installation position and connected to the main housing 8 via stop bolts, again forming a labyrinth seal structure. This design solves the problems of complex assembly and decreased accuracy after disassembly and assembly in traditional optoelectronic platforms. The sliding fit between the motor shaft end 15 and the bearing ensures stable shaft system accuracy before and after disassembly and assembly. A pitch filter module 19 and a power isolation module 20 are respectively installed on both sides of the elevation / lowering frame 17, separating video and power signals to cut off electromagnetic coupling channels and further reduce electromagnetic interference. The manual locking pin 18 is made of stainless steel and has a built-in spring for reset, enabling manual locking and unlocking of the high and low groups 2 at the zero position. It has a compact structure, reduces the span, and solves the problem of redundancy and complexity in traditional locking mechanisms.

A removable sealing structure 28 is installed on the front shell 9. The sealing structure 28 includes sealing ring 1 29, sealing ring 2 30, sealing ring 31, and O-ring 32. Sealing ring 1 29 is connected to the front shell 9 by screws and is equipped with double O-ring 32. Sealing ring 2 30 and sealing ring 31 are connected by threads to form a multi-layer seal to prevent dust and moisture from entering. The rear shell 10 is equipped with two copper gas nozzles 33, one for high-purity nitrogen inlet and one for exhaust. The chamber pressure can reach 20Kpa±2Kpa, and the pressure drop within 10 minutes does not exceed 5%, solving the problems of difficult maintenance and insufficient airtightness of traditional adhesive sealing.

[0036] Horizontal assembly 1 and high / low assembly 2 are connected by bolts with multi-layered stop structures at the top and bottom, forming a labyrinth seal to solve the technical problem of seal failure in high humidity environments. High / low assembly 2 and cabin assembly 3 are connected by stop fits at both ends of the main shell 8. The motor shaft end 15 and the angle measuring shaft end 16 respectively form labyrinth seals with the main shell 8, ensuring assembly accuracy and airtightness, and solving the problem of decreased accuracy after disassembly and assembly. Each module adopts a modular design. The stop fits and bolt connections facilitate disassembly and assembly. The positioning pin 11 and the sliding fit of the motor shaft end 15 ensure assembly accuracy, solving the problem of inconvenient maintenance of traditional optoelectronic platforms. The electromagnetic brake 14 and manual locking pin 18 provide a simple and reliable locking function, solving the problems of complexity and low accuracy of traditional locking mechanisms. The shielding filter module and the metal shielding cover effectively reduce electromagnetic radiation, solving the problem of excessive RE102 in complex electromagnetic environments.

[0037] This utility model's optoelectronic platform achieves azimuth rotation through the horizontal assembly 1, with the horizontal axis component 4 driving the platform's rotation.
