Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a waterproof gimbal for UAVs with underwater image acquisition capabilities. Background Technology

[0002] According to the utility model disclosed in Chinese Patent Publication No. CN217649625U, a drone belongs to the field of drone technology. It includes a drone body with a connecting frame fixedly connected to its bottom. A threaded rod passes through the outer wall of the connecting frame. A rotating guide block, slidably connected to the inner wall of the connecting frame, is threadedly connected to the outer wall of the threaded rod. A swinging perforated plate, spun to the inner wall of the connecting frame, is movably connected to the outer wall of the rotating guide block. A rotating guide groove is provided at the connection between the swinging perforated plate and the rotating guide block. This utility model, by setting a support bracket, allows the threaded slider to slide, causing two sets of lifting perforated plates to slide synchronously. This, in turn, causes the lifting perforated plates to drive the lifting inclined groove to slide. The sliding of the lifting inclined groove, through a guide post, causes a connecting slide rod to slide along the inner wall of the connecting frame. The sliding of the connecting slide rod, through the sliding perforated plate, causes a turning plate to rotate. The rotation of the turning plate causes the support bracket to rotate, thus realizing the retraction and extension operation of the support bracket.

[0003] The aforementioned documents and existing technologies have the following technical problems: the existing underwater drone camera gimbals are prone to shell cracking and water seepage due to collisions with reefs or schools of fish, which can cause electronic short circuits and equipment failures; the lack of an effective waterproof and collision-resistant design makes it difficult to maintain stability and safety in high-pressure underwater environments (such as rescue missions). Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof gimbal for unmanned aerial vehicles (UAVs) with underwater image acquisition capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof gimbal for a drone with underwater image acquisition function, comprising a body, a camera gimbal on the bottom surface of the body, a waterproof shell on the side of the camera gimbal, a waterproof cover on the surface of the camera gimbal, a protective shell on the surface of the waterproof shell, a first support frame inside the protective shell, a first buffer layer inside the first support frame, and a protective cover on the surface of the waterproof cover.

[0006] Preferably, the protective cover has a second support frame inside, and the second support frame has a second buffer layer inside.

[0007] Preferably, the waterproof shell is disposed on all four sides of the camera gimbal, and the waterproof cover is disposed on the top and bottom surfaces of the camera gimbal.

[0008] Preferably, the surface of the waterproof cover is provided with a first mounting bolt, and the waterproof cover is connected to the surface of the waterproof shell through the first mounting bolt.

[0009] Preferably, the protective shell is disposed on all four sides of the waterproof shell, and the protective cover is disposed symmetrically on the surface of the protective shell.

[0010] Preferably, the surface of the protective cover is provided with a second mounting bolt, and the protective cover is connected to the surface of the protective shell through the second mounting bolt.

[0011] Preferably, the shape of the first support frame is adapted to the shape of the first buffer layer, and the shapes of the first support frame and the first buffer layer are adapted to the shape of the protective shell.

[0012] Beneficial effects This invention employs a waterproof shell, a protective shell, a first support frame, and a first buffer layer. The waterproof shell and cover tightly enclose the camera gimbal, forming a multi-layered sealing barrier that effectively prevents water seepage under high pressure. The protective shell and cover are made of high-strength carbon fiber reinforced polymer and flexible silicone rubber coating, ensuring lightweight and corrosion resistance. The first support frame is a multi-layered mesh, forming a honeycomb cavity. When an external impact occurs, the frame can evenly distribute the force, avoiding stress concentration points. The first buffer layer, filled internally, is a closed-cell foam material, arranged in layers—a high-density outer layer and a low-density inner layer—to absorb shock waves in a gradual manner, significantly enhancing impact resistance and protecting the camera gimbal from mechanical damage. Through the multi-layered sealing barrier, the gimbal's impact resistance and waterproof performance are significantly improved, ensuring the stability and safety of the equipment in high-pressure scenarios such as underwater rescue.

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-5 A waterproof gimbal for an unmanned aerial vehicle (UAV) with underwater image acquisition capabilities includes a body 1. A camera gimbal 2 is mounted on the bottom of the body 1. The body 1 serves as the main structure of the entire UAV system, providing core support and a power platform to carry and integrate all functional modules. It also integrates the image acquisition function of the camera gimbal 2 with the UAV's flight capabilities, forming a comprehensive system architecture for underwater operations. The camera gimbal 2 uses a three-axis rotation device (horizontal, pitch, and yaw) on its top surface to dynamically adjust the camera angle in underwater turbulence, maintaining image acquisition stability. It supports high-definition image acquisition via its camera, ensuring clear and stable images in underwater rescue or exploration scenarios. The camera gimbal 2 has a waterproof shell 3 on its side and waterproof covers 4 on its upper and lower surfaces. The waterproof shell 3 is located on all four sides of the camera gimbal 2, and the waterproof covers 4 are located on the top and bottom surfaces of the camera gimbal 2. The surface of the waterproof cover 4 is provided with a first mounting bolt 5, and the waterproof cover 4 is connected to the surface of the waterproof shell 3 through the first mounting bolt 5. The waterproof shell 3 is located on all four sides of the camera gimbal 2 and is made of high-strength carbon fiber reinforced polymer material combined with a flexible silicone rubber coating. It has lightweight and corrosion-resistant properties and can withstand high-pressure environments at water depths of over 50 meters. Through a tight connection with the waterproof cover 4, it forms a multi-layer sealing barrier, effectively preventing water seepage under high pressure and protecting the motor and electronic components inside the camera gimbal 2 from water corrosion, ensuring the reliability of the equipment during long-term immersion operation. One side of the waterproof shell 3 is open and has a waterproof transparent glass, which is located in front of the camera protecting the camera gimbal 2. The waterproof cover 4 is firmly connected to the waterproof shell 3 through the first mounting bolt 5, forming a closed sealing structure, further enhancing the waterproof performance of the gimbal.

[0018] The surface of the waterproof shell 3 is provided with a protective shell 6, which covers all four sides of the waterproof shell 3. Inside the protective shell 6 is a first support frame 7, extending beyond the top of the protective shell 6. Inside the first support frame 7 is a first buffer layer 8, extending beyond the top of the first support frame 7. The shape of the first support frame 7 and the first buffer layer 8 are adapted to each other. The shapes of the first support frame 7 and the first buffer layer 8 are adapted to the protective shell 6. The surface of the waterproof cover 4 is provided with a protective cover 9, which is axially symmetrically arranged on the protective shell 6. The protective cover 9 has a second mounting bolt 10 on its surface, which connects it to the surface of the protective shell 6. Inside the protective cover 9 is a second support frame 11, and inside the second support frame 11 is a second buffer layer 12. The protective shell 6 is located on all four sides of the waterproof shell 3, made of CFRP material combined with a silicone rubber coating, making it lightweight and corrosion-resistant. It forms a comprehensive anti-collision barrier through axial symmetrical connection with the protective cover 9, protecting the camera gimbal 2 module from impacts by rocks, fish, and other objects. Protective lenses are located on its sides, positioned near the camera. The first support frame 7 adopts a multi-layered mesh design, forming a honeycomb cavity. Its shape is adapted to the protective shell 6 and the first buffer layer 8. When an external impact occurs, the frame distributes the force evenly through the honeycomb structure, avoiding stress concentration that could lead to breakage. This significantly enhances the impact resistance of the protective shell 6 and protects the internal components of the camera gimbal 2 from mechanical damage. The first buffer layer 8 is filled with closed-cell foam material, arranged in layers (high density on the outer layer and low density on the inner layer). Its shape is adapted to the first support frame 7 and the protective shell 6. When a collision occurs, the first buffer layer 8 absorbs the impact in a gradual manner. The shock wave reduces the transmission of vibration to the camera gimbal 2 module. Its high resilience ensures that it still maintains its protective effect after multiple impacts, significantly improving the durability of the equipment in scenarios such as underwater rescue. The protective cover 9 is axially symmetrically arranged and is connected to the protective shell 6 through the second mounting bolt 10. It adopts CFRP and silicone rubber coating and forms a unified anti-collision shell with the protective shell 6. It protects the waterproof cover 4 from direct impact, and works with the internal second support frame 11 and second buffer layer 12 to disperse the impact force, ensuring the structural integrity and safety of the camera gimbal 2 in the high-pressure underwater environment. Specific Implementation Example 2: A waterproof gimbal for a drone with underwater image acquisition capability, based on the basic structure in Specific Embodiment 1, further discloses the following: The operation process of the device is as follows: First, the camera gimbal 2 is fixed to the bottom surface of the body 1 via a three-axis rotating device (located on and connected to the protective cover 9). The camera gimbal 2 and the three-axis rotating device are connected to the drone's flight control system through pre-drilled mounting holes, and the holes are tightly sealed with sealing rings and waterproof strips to ensure the waterproof integrity of the wiring and structural interfaces in the underwater environment. Subsequently, a waterproof shell 3 is assembled on all four sides of the camera gimbal 2, and the waterproof cover 4 is connected to the top and bottom surfaces via a first mounting bolt 5, forming a multi-layered sealing barrier. At the same time, the waterproof transparent glass on the side of the waterproof shell 3 is aligned with the camera position to allow high-definition image acquisition. Next, a protective shell 6 is installed on the surface of the waterproof shell 3 and connected via a second mounting bolt 10. The protective cover 9 ensures that the protective lens on the side of the protective shell 6 covers the front of the camera, providing additional anti-collision protection. The first support frame 7 and the first buffer layer 8 are embedded inside the protective shell 6, and the second support frame 11 and the second buffer layer 12 are embedded inside the protective cover 9. During assembly, these structures are connected to the sensors and control circuits through reserved holes and sealed with O-rings to prevent water leakage. In actual underwater use, after the drone dives into the water, the three-axis rotation mechanism of the camera gimbal 2 dynamically adjusts the camera angle to capture clear and stable images. At the same time, the waterproof shell 3 and the waterproof cover 4 block high-pressure water leakage. The protective shell 6 and the protective cover 9, combined with the internal honeycomb support frame and gradient buffer layer, evenly distribute and absorb the impact force when encountering reefs or schools of fish, ensuring stable operation of the equipment and real-time transmission of image data. The entire process requires no frequent maintenance and supports long-term underwater rescue or exploration missions.

[0020] In summary: The camera gimbal 2 is tightly wrapped by a waterproof shell 3, a protective shell 6, a first support frame 7, and a first buffer layer 8. This multi-layered sealing barrier effectively prevents water seepage under high pressure. The protective shell 6 and the protective cover 9 are made of high-strength carbon fiber reinforced polymer and flexible silicone rubber coating to ensure lightweight and corrosion resistance. The first support frame 7 is a multi-layered mesh that forms a honeycomb cavity. When an external impact occurs, the frame can evenly distribute the force and avoid stress concentration. The first buffer layer 8 is filled with closed-cell foam material, arranged in layers of high density on the outside and low density on the inside, absorbing shock waves in a gradual manner, significantly enhancing impact resistance and protecting the camera gimbal 2 from mechanical damage. Through the multi-layered sealing barrier, the impact resistance and waterproof performance of the camera gimbal 2 are significantly improved, ensuring the stability and safety of the equipment in high-pressure scenarios such as underwater rescue.
