Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a ground-following flight UAV. Background Technology

[0002] Terrain-following drones, equipped with lidar, millimeter-wave radar, visual sensors, and high-precision inertial navigation systems, can scan the ground terrain in real time, generate three-dimensional environmental models, and achieve centimeter-level obstacle avoidance and terrain following. Traditional drones are prone to collision risks due to terrain undulations, while terrain-following drones can automatically adjust their flight altitude according to the terrain, maintain a constant distance from the ground, and significantly improve flight stability in complex environments.

[0003] Visual navigation-based terrain-following drones use visual sensors as their core sensing units and combine algorithms to achieve terrain-adaptive flight. Their working principle revolves around visual information acquisition, processing, and control execution. The drone is equipped with visual sensors such as RGB and infrared cameras, continuously acquiring images during flight. Optical lenses focus ambient light onto CMOS / CCD image sensors, and pixel units convert light signals into electrical signals, generating raw image data.

[0004] In existing technologies, some drones have fixed fuselage structures, occupy a large space, cannot be accommodated in ordinary backpacks, and have poor transportation flexibility. If transported by public transportation, they may be damaged by collisions during transportation, which will only increase the burden of travel. Therefore, a ground-following drone is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ground-following unmanned aerial vehicle (UAV) that aims to improve the problems of large space occupation, poor transportation flexibility, and increased travel burden in the existing technology.

[0007] A ground-following unmanned aerial vehicle (UAV) includes a fuselage. A motor is fixedly connected inside the fuselage. A rotating disk is fixedly connected to the drive end of the motor. Multiple transmission columns are fixedly connected to the inner wall of the rotating disk. Connecting plates are rotatably connected to the outer walls of the multiple transmission columns. Multiple connecting columns are rotatably connected to the inner walls of the multiple connecting plates. Sliding plates are rotatably connected to the inner walls of the multiple connecting columns. Multiple fixed plates are slidably connected to the outer walls of the multiple sliding plates. An installation assembly for easy installation is installed inside the fuselage.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes a second motor, the outer wall of which is fixedly connected to the inner wall of the machine body. A gear is fixedly connected to the drive end of the second motor. A rack two is slidably connected to the inner wall of the machine body. A rack one is slidably connected to the inner wall of the machine body. The outer sides of the gear and the outer sides of the rack two are meshed with each other.

[0010] As a further description of the above technical solution:

[0011] A support block is fixedly connected to the outer wall of the rack, and the outer wall of the support block is slidably connected to the inner wall of the machine body.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when storing the drone, the motor is started, and its drive end drives the rotating disk and transmission column to rotate. The sliding plate is pulled by the connecting plate and connecting column to slide linearly on the inner wall of the fixed plate to realize the retraction of the component. When the motor reverses, the component moves in the opposite direction to unfold, so that the drone can quickly enter the working state. This retractable design can greatly reduce the size of the drone, making it easy to carry and store, saving space, reducing the risk of component damage during transportation, improving safety and durability, and meeting the needs of different scenarios.

[0024] 2. In this utility model, when installing the camera, the motor is started, and its drive end drives the gear to rotate clockwise, causing the two meshing racks to move in opposite directions, respectively pulling the support block and the connecting shaft to drive the two sets of clamps to move in opposite directions to loosen them, so that the equipment can be installed. When the motor reverses, the gear and rack drive in the opposite direction, and the clamps clamp synchronously to ensure stable shooting. Attached Figure Description

The outer wall of the second motor 10 is fixedly connected to the inner wall of the body 1. The drive end of the second motor 10 is fixedly connected to the gear 11, which drives a rack 12 and a rack 2 15 that mesh with it. The inner wall of the body 1 is slidably connected to the rack 2 15, which drives a support block 2 16. The inner wall of the body 1 is slidably connected to the rack 12, which drives a support block 13. The outer surfaces of the gear 11 and the rack 2 15 are meshed with each other. The outer surfaces of the gear 11 and the rack 12 are meshed with each other. The outer wall of the rack 12 is fixedly connected to the support block 13, which drives a connecting shaft 19.

[0036] Working principle: When the drone needs to be stored, motor 8 is started. The drive end of motor 8 starts to operate, driving the rotating disk 7 to rotate. The rotation of the rotating disk 7 drives the transmission column 6, which in turn moves accordingly. Thanks to its ingenious connection structure with the connecting plate 5, the power is transmitted to the connecting plate 5. After the connecting plate 5 is subjected to force, it drives the connecting column 4. The connecting column 4 is tightly connected to the sliding plate 3, thereby pulling the sliding plate 3 to slide linearly on the inner wall of the fixed plate 2, realizing the retraction of the parts and completing the storage of the drone. Conversely, when motor 8 is reversed, it moves in the opposite direction, realizing the unfolding of the parts and allowing the drone to quickly enter the working state.

[0037] When the camera needs to be installed, start motor 10. Its drive end drives gear 11 to rotate clockwise. Gear 11 drives rack 12 and rack 2 15, which mesh with it, to move in opposite directions. Rack 12 pulls support block 13, which drives clamping plate 14 through connecting shaft 19. Rack 2 15 drives support block 2 16, which drives clamping plate 2 17 through connecting shaft 2 18. Finally, the two sets of clamping plates move in opposite directions to release the camera. At this time, the camera can be installed easily. After adjusting to the appropriate position, motor 10 reverses, the gear and rack drive in the opposite direction, and clamping plate 14 and clamping plate 2 17 clamp the equipment synchronously to ensure stability and no shaking during shooting.
