Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle lighting, in particular to an adjustable unmanned aerial vehicle lighting structure. Background Art

[0002] A tethered drone is a drone system that can hover in the air for a long time by connecting to a ground power supply. It has the characteristics of large load, long flight time, fast erection, simple operation, strong environmental adaptability, and flexible adjustment of operating height. This drone can carry a variety of mission payloads, such as communication base stations, optoelectronic pods, etc., and can provide various auxiliary functions in disaster rescue. Some existing tethered drones have LED light panels installed on the four arms by bolts, but their position and angle on the arms cannot be changed, and the light directly below the drone is always weak. When conducting search and rescue operations in the disaster area at night, after determining the location of the rescue personnel, it is not convenient to focus on the rescue position. The overall brightness can only be improved by increasing the brightness of the LED light panel, and the position of the light panel is fixed. The illumination range can only be expanded by lifting the drone. After lifting, the illumination brightness needs to be further increased due to the distance from the ground, which increases energy consumption, making it inconvenient to assist rescue personnel in searching and exploring the disaster area, and inconvenient to use.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, an adjustable UAV lighting structure includes: the UAV body 10, and a plurality of arms 11 are fixedly connected to the outer wall of the UAV body 10 at equal intervals; a plurality of limit sleeves 20 are movably clamped on the outer wall of adjacent arms 11, and snap rings 21 are rotatably connected to both ends of the limit sleeve 20, and the control board 22 is movably clamped at the bottom of the snap ring 21; the LED light board 23 is rotatably connected to the bottom of the control board 22, and a protective shell 231 is fixedly connected to the bottom of the LED light board 23; the control module 24 is arranged inside the limit sleeve 20 for driving the snap ring 21, one end of the arm 11 is fixedly connected with a propeller base 12, a propeller blade 121 is rotatably connected to the top of the propeller base 12, and a tether cable 13 is fixedly connected to the bottom of the UAV body 10.

[0030] Specifically, an LED light board 23 is rotatably connected to the bottom of the control board 22. Starting the second electric push rod 243 can drive the clamping ring 21 to swing reciprocally, thereby driving the LED light board 23 to adjust its orientation reciprocally, facilitating the expansion of the detection range of the disaster area. Simultaneously starting multiple first electric push rods 233 can adjust the angles of multiple LED light boards 23, converging the light rays of multiple LED light boards 23 downward, facilitating the enhancement of the illumination at the rescue site, providing better lighting conditions for rescue operations, and being convenient to use. The propeller base 12 and the propeller blades 121 provide power for the lifting of the UAV body 10, and the tethered cable 13 is used to supply power to the UAV body 10 and the LED light board 23.

[0031] Embodiment 1

[0032] As Figures 1 - 3 shown, in this embodiment, two clamping plates 211 are fixedly connected to the bottom of the clamping ring 21, and two docking plates 221 are symmetrically and fixedly connected to the top of the control board 22. The clamping plates 211 can be movably clamped with the adjacent docking plates 221. A shaft plate 232 is rotatably connected to the bottom of the control board 22, and the shaft plate 232 is fixedly connected to the top of the LED light board 23. A first electric push rod 233 is rotatably connected to the bottom of the control board 22, and the output end of the first electric push rod 233 is rotatably connected to the top of the LED light board 23. Limiting grooves 203 are provided on both sides of the limiting sleeve 20.

[0033] In this embodiment, when the two limiting sleeves 20 are docked, the two clamping plates 211 are inserted into the adjacent docking plates 221, thereby connecting the clamping ring 21 and the control board 22 and being able to reinforce the connection at the lower ends of the two clamping rings 21. When the two groups of clamping rings 21 rotate, they can drive the control board 22 and the LED light board 23 to rotate, thereby regulating the irradiation direction of the LED light board 23. Through the limitation of the shaft plate 232 by the control board 22, the rotational limitation of the LED light board 23 is realized. Starting the first electric push rod 233 can drive the LED light board 23 to rotate, regulating the angle of the LED light board 23, and converging and strengthening the irradiation of the light rays of multiple LED light boards 23 towards the middle.

[0034] As Figure 4 shown, in this embodiment, a mounting plate 201 is fixedly connected to the top end of the limiting sleeve 20, and a positioning shell 202 is fixedly connected to the outer wall of the limiting sleeve 20. The positioning shell 202 can be movably clamped with the propeller base 12.

[0035] During specific implementation, after the two limit sleeves 20 are butted, the two limit sleeves 20 are connected and reinforced by bolts in cooperation with the two mounting plates 201. At this time, when the bolts are not tightened yet, the two limit sleeves 20 can rotate on the machine arm 11. At this time, calibration can be carried out through the docking of the positioning shell 202 and the propeller base 12, so that the LED light board 23 can be kept as horizontal as possible, and then the bolts on the two mounting plates 201 are tightened to reinforce the two limit sleeves 20.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, in order to be able to drive multiple LED light boards 23 to swing reciprocally, increase the irradiation range, and facilitate the cooperation of search and rescue personnel to search the disaster area.

[0038] As Figures 1 - 5 shown, in this embodiment, the control module 24 includes: a plurality of arc-shaped sliders 241 are slidably connected between the inner walls of the limit sleeve 20. One side of the arc-shaped slider 241 is fixedly connected with a connecting rod 2411. The connecting rod 2411 penetrates through the limit groove 203 and is fixedly connected with the adjacent snap ring 21; a round rod 2412 is rotatably connected to the other side of the arc-shaped slider 241; a plurality of electric push rods II 243 and fixed pulleys 244 are fixedly connected between the inner walls of the limit sleeve 20. The output end of the electric push rod II 243 is rotatably connected with a steel wire rope 245. The steel wire rope 245 bypasses the fixed pulley 244 and is fixedly connected with the round rod 2412. Two guiding frames 242 are symmetrically fixedly connected between the inner walls of the limit sleeve 20. The steel wire rope 245 penetrates through the adjacent guiding frame 242 and is movably clamped with it.

[0039] During specific implementation, through the limitation of the arc-shaped slider 241 by the limit sleeve 20, the rotational limitation of the snap ring 21 is realized. When the two snap rings 21 are butted, the rotations of the two snap rings 21 are synchronized. The electric push rod II 243 on one side in the limit sleeve 20 is started to pull the steel wire rope 245, thereby driving the arc-shaped slider 241 to move. The fixed pulley 244 guides the direction of the steel wire rope 245. The arc-shaped slider 241 drives the snap ring 21 to rotate through the connecting rod 2411. The snap ring 21 drives the control board 22 and the LED light board 23 to rotate, and the direction of the LED light board 23 is adjusted. The path of the steel wire rope 245 is guided by the guiding frame 242 to prevent the guiding frame 242 from generating more friction with the inner wall of the limit sleeve 20, ensure the stable drive of the electric push rod II 243, and extend the service life of the guiding frame 242.
