Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle technology, and in particular to an integrated bracket for an underwater unmanned aerial vehicle cabin camera. Background Technology

[0002] Underwater drones, as an important underwater detection device, have been widely used in various fields such as marine scientific research, aquaculture, underwater inspection, and rescue and salvage. One of their core functions is to conduct real-time underwater observation and data collection through onboard cameras. Therefore, the stability, flexibility, and reliability of the camera system directly determine the operational efficiency of underwater drones.

[0003] The sealed hull of an underwater drone is a crucial component ensuring the operation of its electronic components underwater. With the rapid advancement of technology, as people explore the sky, they also explore the underwater world. The use of underwater drones reduces the risks and costs of underwater exploration. Therefore, the rational layout of the underwater sealed hull and the expansion of visibility in all aspects of the underwater environment are particularly important.

[0004] Traditional cabin support structures are mostly modular, with core components such as flight controllers, host computers, servos, and cameras typically secured by independent brackets or simple binding methods. This layout not only occupies a large amount of space, resulting in low cabin space utilization, but also lacks a unified rigid connection between components, leading to insufficient overall structural strength. In the complex underwater environment, impacts from water flow or equipment vibrations can easily cause components to loosen, shift, or even interfere with each other, affecting equipment lifespan and operational stability.

[0005] Many existing designs rigidly mount cameras directly to the hull or simple gimbal, lacking effective shock absorption and flexible attitude adjustment capabilities. This results in cameras failing to remain stable when the drone is moving or disturbed by water currents, causing severe shaking in the captured images and affecting observation quality. Furthermore, the fixed viewing angle limits the field of view, preventing flexible adjustments to capture specific targets and significantly hindering the efficiency and effectiveness of underwater detection.

[0006] Therefore, there is an urgent need for an integrated, modular, and highly rigid internal support structure that can compactly and stably integrate the core components of underwater drones and provide stable and flexible multi-degree-of-freedom motion capabilities for cameras, thereby comprehensively improving the overall performance, reliability, and ease of use of underwater drones. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated camera mount for underwater drones, addressing the problems existing in the prior art.
