Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle equipment, and in particular to a multifunctional unmanned aerial vehicle camera protection device and a working method thereof. Background Art

[0002] With the rapid development of drone technology, drones have been widely used in many fields such as aerial photography, environmental monitoring, agricultural plant protection, disaster assessment, etc. As an important component of drones, the stability of drone camera performance and the diversity of its functions directly affect the application effect of drones. Especially in the field of aerial photography, drone cameras play a key role in obtaining high-quality aerial images and videos. However, in actual application, drone cameras may collide with objects near the ground during take-off and landing due to instability, causing damage, which has become an important factor restricting the effect of drone aerial photography.

[0003] In order to solve this problem, a variety of drone camera protection devices have been proposed. Most of these devices use a cover to cover the camera to provide physical protection. However, this method has some shortcomings. First, the cover protecting the camera may reduce the clarity of the image. The material and quality of the cover may introduce optical distortion, resulting in a decrease in image quality. The refraction and scattering of light through the cover may cause blur, distortion, and light spots, affecting the details and clarity of the image. Secondly, in a strong light environment, the surface of the cover may produce reflections, interfere with the camera's photosensitive elements, cause light spots or reflections in the image, and thus reduce the image quality. In addition, when the aerial drone is looking horizontally, the camera's line of sight is often blocked by the drone's tripod, which limits the camera's field of view and makes it impossible to obtain a full shooting angle. This is a significant technical deficiency for tasks that require all-round shooting.

[0004] In order to overcome these technical difficulties, the industry has begun to explore new drone camera protection devices. For example, CN116639284A discloses a drone camera protection device, which protects the camera through a floating plate and a petal-shaped baffle design under the connecting plate, and can adjust the shooting angle to a certain extent. However, the structure of the device is relatively complex, and multiple components need to work together to open and close the baffle, which increases the failure rate and maintenance cost of the device to a certain extent.

[0005] Therefore, it is necessary to develop a more efficient, concise and multifunctional drone camera protection device to overcome the shortcomings of the prior art. This application is proposed in this technical background, aiming to provide an innovative design solution that can effectively protect drone cameras, provide clear shooting angles, simplify the operating structure and adapt to the fully automatic operation mode. Through this solution, the drone camera protection device can provide a higher quality, safer and more reliable solution for aerial photography tasks while protecting the camera.

[0029] Example 2 In another preferred embodiment, a working method of a multifunctional drone camera protection device is to use any of the multifunctional drone camera protection devices described above, and the method comprises the following steps: Step 1: After a multifunctional drone camera protection device is installed on a drone and debugged to be qualified, the device and the drone system are turned on to enter a standby state, ensuring that the components are connected and that the control system of the operator communicates normally; in a normal standby state, the camera body 4 is located at the center of the device and the camera lens 41 is protected by a camera protection plate 33, the camera protection shell 32 is horizontal to the drone take-off plane to protect the bottom of the camera body 4, and the first support rod 221 and the second support rod 222 of the support assembly 22 are downward and slightly tilted outward to support the entire drone body; Step 2: When the drone receives the take-off signal, it leaves the ground and goes to the target survey location according to the predetermined procedure. Before arriving at the shooting location, the device is in a standby state, that is, the camera body 4 is continuously protected by the device during this process, and the drone support frame 2 is still in a supporting state; Step 3: When the UAV arrives at the target survey site, the device receives a corresponding signal, causing the servo motor 21 to drive the support assembly 22 to rotate in a direction away from the fuselage until the bottom end of the third support rod 223 is level with the top end of the camera lens 41 and stops rotating; during this process, the servo motor 21 drives the first driven wheel 311 to rotate synchronously through the multi-stage gear 11, thereby driving the crawler 310, and delivering the camera body 4 as a whole toward the ground. The camera protective shell 32 is also opened with the rotation of the crawler 310 until the camera lens 41 is completely exposed from the camera protective plate 33, and the camera protective shell 32 in the final working state is perpendicular to the ground. Step 4: When the video mission is completed, the UAV leaves the target survey area; the device receives the corresponding signal, causing the servo motor 21 to drive the support assembly 22 to rotate in the direction close to the fuselage until the support assembly 22 returns to the device standby state in Step 1; during this process, the servo motor 21 drives the first driven wheel 311 to rotate synchronously through the multi-stage gear 11, thereby driving the crawler 310 to retract the camera body 4 delivered toward the ground in Step 3. Finally, the working states of the various components of the device are the same as the device standby state in Step 1.

[0030] Example 3 In another preferred embodiment, based on the above embodiments 1 and 2, this embodiment provides a multifunctional drone camera protection device and a working method thereof, the structure of which is as follows: Figures 1 to 3 As shown, the functions and working methods of each part are described as follows: The present invention provides a multifunctional drone camera protection device, which specifically includes a base 1, a drone support frame 2, a camera telescopic component 3 and a camera body 4.

[0031] The base 1 is a double-layer hollow structure, including a base outer layer 111, a base middle layer 112 and a base bottom layer 113. A multi-stage gear 11 is arranged in the base middle layer 112, and these gears are respectively engaged with the gears of the servo motor 21 and the first driven wheel 311 to ensure the accuracy and stability of power transmission.

[0032] The drone support frame 2 includes a servo motor 21 and a support assembly 22. The servo motor 21 is embedded in the base 1, and its rotating shaft is connected to the multi-stage gear 11 through a gear, so that its rotation angle and speed can be accurately controlled. The support assembly 22 includes a first support rod 221 fixed on the rotating shaft of the servo motor 21, a second support rod 222 rotatably connected to the back of the high-precision servo motor 21, and a third support rod 223 fixed to the other end of the first support rod 221 and the second support rod 222. This design allows the support frame 2 to open and close under the drive of the high-precision servo motor 21, providing stable support for the drone.

[0033] The camera telescopic assembly 3 includes a crawler delivery assembly 31, a camera protection shell 32 and a camera protection plate 33. The crawler delivery assembly 31 is composed of a crawler 310, a first driven wheel 311 and a second driven wheel 312 supporting the crawler 310, and a crawler outer plate 313 covering the front of the crawler delivery assembly 31. The camera protection shell 32 is fixed on the crawler 310, covering the camera body 4 directly below, and plays a protective role. The camera protection plate 33 is fixed on the crawler outer plate 313, covering the front part of the camera body 4, and further enhancing the protective effect.

[0034] The camera body 4 includes a camera lens 41 and a camera data processing and communication component 42 fixed on the left and right crawlers 310. The camera lens 41 is used to capture images and videos, while the camera data processing and communication component 42 is responsible for processing and transmitting these data.

[0035] Here’s how it works: In normal standby mode (such as Figure 1 As shown in FIG. 1 , the camera body 4 is located in the center of the device, and the lens 41 is protected by the camera protection plate 33. The camera protection shell 32 is horizontal to the take-off plane of the drone to protect the bottom of the camera body 4. The first support rod 221 and the second support rod 222 of the support assembly 22 are tilted downward and slightly outward to support the entire drone body.

[0036] When the drone takes off and heads for the target survey site, the device remains in a standby state, the camera body 4 continues to be protected, and the drone support frame 2 remains in a supporting state.

[0037] When the drone arrives at the target survey location, the device receives the signal, and the high-precision servo motor 21 drives the support assembly 22 to rotate in a direction away from the fuselage until the lower end of the third support rod 223 is level with the upper end of the lens 41 and stops rotating (such as Figure 2 As shown in FIG. 1 ). During this process, the high-precision servo motor 21 drives the first driven wheel 331 to rotate synchronously through the multi-stage gear 11, thereby driving the crawler 310 to deliver the camera body 4 as a whole to the ground. The camera protection shell 32 is also opened with the rotation of the crawler 310 until the camera lens 41 is completely exposed from the camera protection plate 33. At this time, the camera protection shell 32 is perpendicular to the ground, providing a wide field of view for the camera.

[0038] After the video mission is completed, the drone leaves the target survey area. The device receives the signal again, and the high-precision servo motor 21 drives the support assembly 22 to rotate in the direction close to the fuselage until it returns to the standby state. At the same time, the crawler 310 also retracts the camera body 4, and the working state of each component is the same as the standby state.

[0039] Example 4 In another preferred embodiment, based on the above-mentioned embodiment 3, this embodiment further demonstrates the versatility of the device of the present invention.

[0040] In addition to the basic camera protection and delivery functions, the present invention can also integrate other functional modules. For example, components such as a humidity meter and a thermal imager can be installed next to the camera lens 41, and these components are also protected by the camera protection shell 32 and the camera protection plate 33. This design makes the present invention have a wider application prospect in the fields of forestry surveying, environmental monitoring, etc.

The precise control of the servo motor 21 ensures the stable opening and closing of the support assembly 22, providing reliable support and protection for the UAV.

[0048] In the preferred solution, the servo motor 21 is installed in the base 1 or under the UAV support frame 2, and is connected to the support assembly 22 through a multi-stage gear transmission system formed by a multi-stage gear 11 to achieve precise control; the above setting not only ensures the stability of the servo motor 21 during operation, but also effectively reduces the space occupancy.

[0055] At the same time, the device also shows strong adaptability and scalability. The device can remain in standby mode before reaching the shooting destination to maximize the safety of the camera body. At the same time, the four parts of the camera body can integrate modules such as humidity and temperature sensors, night vision devices, and radar systems to meet the needs of different survey tasks. The flexibility and scalability make the device have high application value in the field of drone camera protection devices.

10. A working method of a multifunctional drone camera protection device, characterized in that: A multifunctional drone camera protection device according to any one of claims 1 to 9 is used, and the method comprises the following steps: Step 1: After a multifunctional drone camera protection device is installed on a drone and debugged to be qualified, the device and the drone system are turned on to enter a standby state, ensuring that the various components are connected and that the control system of the operator communicates normally; in a normal standby state, the camera body (4) is located at the center of the device and the camera lens (41) is protected by a camera protection plate (33), the camera protection shell (32) is horizontal to the drone take-off plane to protect the bottom of the camera body (4), and the first support rod (221) and the second support rod (222) of the support assembly (22) are downwardly and slightly tilted outward to support the entire drone body; Step 2: When the drone receives the take-off signal, it leaves the ground and heads to the target survey location according to a predetermined procedure. Before arriving at the filming location, the device is in a standby state, that is, the camera body (4) is continuously protected by the device during this process, and the drone support frame (2) is still in a supporting state; Step 3: When the UAV arrives at the target survey location, the device receives a corresponding signal, causing the high-precision servo motor (21) to drive the support assembly (22) to rotate in a direction away from the fuselage until the bottom end of the third support rod (223) is level with the top end of the camera lens (41) and the rotation stops; during this process, the servo motor (21) drives the first driven wheel (311) to rotate synchronously through the multi-stage gear (11), thereby driving the crawler (310), and delivering the camera body (4) as a whole toward the ground. The camera protection shell (32) is also opened with the rotation of the crawler (310), until the camera lens (41) is completely exposed from the camera protection plate (33), and the camera protection shell (32) in the final working state is perpendicular to the ground direction; Step 4: When the video recording task is completed, the drone leaves the target survey area; the device receives the corresponding signal, causing the servo motor (21) to drive the support assembly (22) to rotate in a direction close to the fuselage until the support assembly (22) returns to the device standby state in Step 1; during this process, the high-precision servo motor (21) drives the first driven wheel (311) to rotate synchronously through the multi-stage gear (11), thereby driving the crawler (310) to retract the camera body (4) delivered to the ground in Step 3. Finally, the working states of the various components of the device are the same as the device standby state in Step 1.
