Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a search and rescue UAV adapted to rescue operations in complex terrain. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by onboard computers, either completely or intermittently. In the field of emergency rescue, UAVs have become an indispensable part of emergency rescue due to their advantages such as mobility, rapid deployment, and multi-functional integration.

[0003] Traditional search and rescue drones typically carry key equipment such as high-definition visible light cameras and infrared thermal imaging cameras when conducting rescue missions in complex terrain. These devices can monitor the disaster area in real time and assess the disaster situation, providing crucial decision-making information for rescue operations. Among them, the dual-light fusion single-IP camera is an important component of the drone, and its performance directly affects the drone's image clarity and monitoring capabilities. However, these cameras are often difficult to disassemble, resulting in low maintenance efficiency, which not only increases maintenance costs but also affects the camera's lifespan and performance stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the camera disassembly process of search and rescue drones is complicated during use, resulting in low maintenance efficiency. To this end, we propose a search and rescue drone that can adapt to rescue in complex terrain.

[0005] To achieve the above objectives, this application adopts the following technical solution: a search and rescue drone adapted to complex terrain rescue, comprising a body, with arms fixed at each of the four corners of the body, folding propellers mounted on the top of the arms, a set-top box mounted on the top of the body, a camera body mounted at the front end of the set-top box, a mounting bracket fixed to the surface of the camera body, first housings fixed to both sides of the mounting bracket, and second housings fixed to both sides of the front end of the set-top box located on both sides of the camera body, with sliding rods slidably connected to both sides inside the second housings, a circular plate fixed to one end of the sliding rod, a movable plate fixed to the other end of the sliding rod, a locking block fixed to the top of the movable plate, and slots for sliding connection with the locking blocks on both sides of the first housings.

[0006] Preferably, both sides inside the second housing are fixed with fixing rods, and the surface of the movable plate is provided with a through groove for sliding connection with the fixing rods.

[0007] Preferably, springs are fixed on both sides inside the second housing, and the other end of the springs is fixed to the movable plate.

[0008] Preferably, the diameter of the slide bar located outside the second housing is larger than the diameter of the card block inserted into the card slot.

[0009] Preferably, both sides of the second housing are provided with through grooves for sliding connection with the slide rod.

[0010] Preferably, the front end of the set-top box has a mounting slot, and one end of the camera body is inserted into the mounting slot.

[0011] Preferably, the camera body is a dual-light fusion single-IP camera.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pressing the circular plate, the sliding rod moves into the interior of the second housing, causing the moving plate to disengage the locking block from the slot, thus releasing the first housing from its fixation. This facilitates the removal of the camera body from the front of the set-top box, enabling quick disassembly and maintenance of the camera body. This improves maintenance efficiency, reduces maintenance and upkeep costs, extends the lifespan of the camera body, and maintains its good working condition. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a search and rescue drone adapted to complex terrain rescue, including a body 1, with arms 2 fixed at each of the four corners of the body 1, folding propellers 3 mounted on the top of the arms 2, a set-top box 4 mounted on the top of the body 1, a camera body 5 mounted at the front end of the set-top box 4, a mounting bracket 6 fixed to the surface of the camera body 5, first housings 7 fixed to both sides of the mounting bracket 6, and second housings 8 fixed to both sides of the front end of the set-top box 4 on both sides of the camera body 5. Sliding rods 9 are slidably connected to both sides inside the second housings 8, a circular plate 10 fixed to one end of the sliding rod 9, and a movable plate 11 fixed to the other end of the sliding rod 9. A [missing information - likely a device or component] is fixed to the top of the movable plate 11. The first housing 7 has slots 13 on both sides that are slidably connected to the locking block 12. By pressing the circular plate 10, the sliding rod 9 is moved into the second housing 8, causing the moving plate 11 to move the locking block 12 out of the slot 13, thus releasing the first housing 7 from its fixation. This makes it easier to remove the camera body 5 from the front of the set-top box 4, thereby facilitating quick disassembly and maintenance of the camera body 5, reducing maintenance and upkeep costs, extending the service life of the camera body 5, and maintaining its good working condition. In addition, the entire unit is made of high-strength, lightweight materials, ensuring that the drone can withstand harsh environments and accidental impacts in complex terrain.

[0021] Reference Figure 4 As shown in this embodiment: both sides of the interior of the second housing 8 are fixed with fixing rods 14, and the surface of the movable plate 11 is provided with a through groove 15 for sliding connection with the fixing rods 14. By setting the structure of fixing rods 14 and through groove 15, the movement trajectory of the movable plate 11 can be restricted to avoid tilting.

[0022] Reference Figure 4 As shown in this embodiment: Springs 16 are fixed on both sides inside the second housing 8. The other end of the springs 16 is fixed to the moving plate 11. By setting the springs 16, when the user presses the round plate 10 to drive the slide rod 9 to pull the moving plate 11 to pull the card block 12 out of the card slot 13, the springs 16 are stretched. When it is necessary to install the camera body 5 at the front end of the set-top box 4, the first housing 7 is reset, and the spring force of the springs 16 is used to push the moving plate 11 to drive the card block 12 to insert into the card slot 13.

[0023] Reference Figure 4 As shown in this embodiment, the diameter of the slide bar 9 outside the second housing 8 is larger than the diameter of the card block 12 inserted into the card slot 13. By designing the diameter of the slide bar 9 outside the second housing 8 to be larger than the diameter of the card block 12 inserted into the card slot 13, it can be ensured that the moving distance of the moving plate 11 can disengage the card block 12 from the inside of the card slot 13.

[0024] Reference Figure 4As shown in this embodiment: both sides of the second housing 8 are provided with through grooves 17 for sliding connection with the slide rod 9. By setting the through grooves 17, the horizontal movement direction of the slide rod 9 can be restricted, thereby improving the stability of the slide rod 9 when it moves.

[0025] Reference Figure 3 As shown in this implementation scheme: the front end of the set-top box 4 is provided with a mounting slot 18, and one end of the camera body 5 is inserted into the inside of the mounting slot 18. By setting the mounting slot 18, the stability of the camera body 5 after installation can be further increased, ensuring that the camera body 5 can still take clear pictures when the drone flies under severe weather conditions such as strong winds and heavy rain.

[0026] Reference Figure 2 and Figure 3 As shown in this implementation scheme: the camera body 5 is a dual-light fusion single IP camera. By adopting a dual-light fusion single IP camera, it is possible to combine infrared thermal imaging and visible light to provide dual-light single IP output and achieve seamless fusion of video images. This camera is not only lightweight, but also able to clearly capture targets during the day and at night. Furthermore, infrared thermal imaging can collect on-site thermal radiation data to help discover objects with temperature differences from the environment, such as trapped personnel or missing persons.

[0027] Working principle: By pressing the circular plate 10, the user moves the sliding rod 9 into the interior of the second housing 8, causing the moving plate 11 to disengage the locking block 12 from the inside of the locking slot 13. This releases the first housing 7, facilitating the removal of the camera body 5 from the front of the set-top box 4. This allows for quick disassembly and maintenance of the camera body 5, reducing maintenance costs, extending its lifespan, and maintaining its optimal working condition. Furthermore, the entire unit is constructed from high-strength, lightweight materials, ensuring the drone can withstand harsh environments and accidental impacts in complex terrain. It also possesses excellent flight performance and maneuverability, enabling flexible flight in complex terrains such as mountains, forests, and deserts, allowing for rapid arrival at rescue sites. An advanced flight control system ensures the drone can operate even in severe weather conditions such as strong winds and heavy rain. The system maintains stable flight. The flight control system utilizes existing mature technology, which will not be described in detail here. The structure of the fixed rod 14 and the through slot 15 restricts the movement trajectory of the moving plate 11, preventing tilting. A spring 16 is used; when the user presses the circular plate 10, it pulls the sliding rod 9, causing the moving plate 11 to pull the locking block 12 out of the slot 13. When the camera body 5 needs to be installed at the front of the set-top box 4, the first housing 7 is reset, and the spring 16's rebound force pushes the moving plate 11, causing the locking block 12 to insert into the slot 13. By designing the diameter of the sliding rod 9 outside the second housing 8 to be larger than the diameter of the locking block 12 inserted into the slot 13, it ensures that the moving distance of the moving plate 11 is sufficient to disengage the locking block 12 from the slot 13.

[0028] By setting the through slot 17, the horizontal movement direction of the slide bar 9 can be restricted, improving the stability of the slide bar 9 during movement. By setting the mounting slot 18, the stability of the camera body 5 after installation can be further increased, ensuring that the camera body 5 can still capture clear images when the drone flies in severe weather conditions such as strong winds and heavy rain. By adopting a dual-light fusion single-IP camera, infrared thermal imaging and visible light can be combined to provide dual-light single-IP output, achieving seamless fusion of video images. This camera is not only lightweight, but also can capture clear images of targets during the day and night. Furthermore, infrared thermal imaging can collect on-site thermal radiation data, helping to discover objects with temperature differences from the environment, such as trapped personnel or missing persons.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
