Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically, to a lighting device mounted on an unmanned aerial vehicle. Background Art

[0002] With the continuous development of drone technology, drones are increasingly used in various fields such as aerial photography, reconnaissance, search and rescue, and inspection, and the demand for their application at night or in dim environments is also growing. At night or in low-light environments, drone flights are restricted, and traditional drone lighting systems often simply mount one or more wired tethered lamps, which lack flexibility and pertinence.

[0003] After searching the patent document with the existing publication number CN117682120A, a night lighting mounting device for unmanned aerial vehicles for power inspection is provided. The device aligns the light emitted by the LED lamp with the direction of the lens on the camera, and provides light to the camera through the light emitted by the LED lamp. The mounting frame can follow the movement of the camera. As long as the camera is shooting, the light can be irradiated, which effectively provides convenience for night work, effectively ensures the safety of working at night or in dimly lit environments, and improves work efficiency.

[0004] Although the above device can provide light to the camera through the LED light to complete the inspection work, the LED light of the above device is set under the drone and can only illuminate the side of the drone, but cannot provide lighting above the drone, which makes it easy for the drone to collide with external obstacles such as buildings and cables during the take-off phase of the power inspection, causing damage to the drone. In order to solve the defects of the above lighting device, we propose a drone-mounted lighting device. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] See also Figure 1 ,The present invention provides a UAV mounted lighting device, comprising a mounting frame 1, a front lamp 2, a rear lamp 3, a reflector 4 and a driving component 5;

[0034] The front lamp 2 and the rear lamp 3 are both rotatably mounted at the bottom of the mounting frame 1, and the number of reflectors 4 is the same as the sum of the number of the front lamp 2 and the rear lamp 3. Preferably, there are two front lamps 2 and two rear lamps 3, and four reflectors 4, which are arranged in an inclined state.

[0035] The device is mounted on the landing gear of the UAV through the mounting frame 1. In the initial state, the front lamp 2 and the rear lamp 3 are tilted to both sides and face the reflector 4. Figure 1 At this time, the light emitted by the front lamp 2 and the rear lamp 3 will be reflected upward by the reflector 4 to illuminate the air above the drone and prevent the drone from colliding with air obstacles during inspection. The cross section of the reflector 4 can be set to be arc-shaped, which can diverge the light upward and increase the irradiation area.

[0036] like Figure 3 As shown, the front lamp 2 is fixedly connected with a first gear 201, and the two first gears 201 are meshed and connected. The rear lamp 3 is fixedly connected with a second gear 301, and the two second gears 301 are meshed and connected. The driving component 5 is used to drive the front lamp 2 and the rear lamp 3 to rotate. Under this design, the driving component 5 only needs to control the rotation of one of the front lamps 2 or the rear lamps 3 to drive the other front lamp 2 or the rear lamp 3 to rotate in a mirror image. Finally, the front lamp 2 and the rear lamp 3 are adjusted to be covered forward, as shown in FIG. Figure 2 The installation height of the rear lamp 3 on the mounting frame 1 is lower than the installation height of the front lamp 2, so as to prevent the front lamp 2 from blocking the light emitted by the rear lamp 3 when the rear lamp 3 turns forward.

[0037] like Figure 4 As shown, the driving assembly 5 includes a driving motor 501, which is fixedly mounted on the mounting frame 1. The output end of the driving motor 501 is fixedly connected to a rotating shaft 502, and a first driving wheel 503 is fixedly connected to the rotating shaft 502. A first driven wheel 504 is drivingly connected to one side of the first driving wheel 503, and the first driven wheel 504 is connected and fixed to one of the front lamps 2. A second driving wheel 505 is fixedly connected to the rotating shaft 502, and a second driven wheel 506 is drivingly connected to one side of the second driving wheel 505, and the second driven wheel 506 is connected and fixed to one of the rear lamps 3. When the rotating shaft 502 is driven to rotate by the driving motor 501, the angle of the front lamp 2 can be adjusted by the first driving wheel 503 and the first driven wheel 504, and the angle of the rear lamp 3 can be adjusted by the second driving wheel 505 and the second driven wheel 506.

[0038] like Figure 5 As shown, a first arc-shaped avoidance groove 5031 is provided on the outer side of the first driving wheel 503, a first arc-shaped tooth 5032 is fixedly connected in the first arc-shaped avoidance groove 5031, a second arc-shaped tooth 5041 is fixedly connected on the outer side of the first driven wheel 504, the first arc-shaped tooth 5032 meshes with the second arc-shaped tooth 5041, and the length of the first arc-shaped tooth 5032 is not less than the length of the second arc-shaped tooth 5041; first limit blocks 5042 are provided on both sides of the second arc-shaped tooth 5041, the first limit blocks 5042 mesh with the first driven wheel 504, and the first limit blocks 5042 are in sliding contact with the outer wall of the first driving wheel 503. In this design, when the first driving wheel 503 rotates and the first arc-shaped tooth 5032 is not meshed with the second arc-shaped tooth 5041, the first limit blocks 5042 will be limited by the first driving wheel 503 to keep the position of the front lamp 2 fixed and prevent the front lamp 2 from shaking.

[0039] like Figure 6 As shown, a second arc-shaped avoidance groove 5051 is provided on the second driving wheel 505, a third arc-shaped tooth 5052 is fixedly connected in the second arc-shaped avoidance groove 5051, a fourth arc-shaped tooth 5061 is fixedly connected to the second driven wheel 506, the third arc-shaped tooth 5052 is meshed and connected with the fourth arc-shaped tooth 5061, second limit blocks 5062 are provided on both sides of the fourth arc-shaped tooth 5061, and the second limit blocks 5062 are fixedly connected with the second driven wheel 506. When the second driving wheel 505 rotates and the third arc-shaped tooth 5052 is not meshed with the fourth arc-shaped tooth 5061, the second limit blocks 5062 will keep the position of the rear lamp 3 fixed under the limiting action of the second driving wheel 505 to prevent the rear lamp 3 from shaking.

[0040] The second driven wheel 506 is eccentrically connected and fixed to the rear lamp 3. When the second driven wheel 506 drives the rear lamp 3 to rotate forward, the two rear lamps 3 can move closer to the middle and maintain a parallel state, thereby increasing the overlapping illumination range of the two rear lamps 3. Figure 2 shown.

[0041] Moreover, the first arc-shaped tooth 5032 and the second arc-shaped tooth 5041, the third arc-shaped tooth 5052 and the fourth arc-shaped tooth 5061 are not engaged at the same time; so that when the driving motor 501 drives the shaft 502 to rotate, the third arc-shaped tooth 5052 and the fourth arc-shaped tooth 5061 are engaged first, and the two rear lamps 3 can rotate forward first and be in a parallel state; then the first arc-shaped tooth 5032 and the second arc-shaped tooth 5041 are engaged, and the front lamp 2 will rotate inward, so as to facilitate the adjustment of the position where the light of the front lamp 2 converges, so as to successfully complete the task of power inspection.
