Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a UAV-mounted lighting device. Background Technology

[0002] With the continuous development of drone technology, drones are increasingly widely used in various fields such as aerial photography, reconnaissance, search and rescue, and inspection, and the demand for their application in nighttime or low-light environments is also growing. In nighttime or low-light environments, drone flight is limited, and traditional drone lighting systems often simply mount one or more wired tethered lights, lacking flexibility and specificity.

[0003] A search of existing patent document CN117682120A reveals a nighttime lighting mounting device for a power line inspection drone. This device aligns the light emitted by an LED light with the lens direction of a camera, providing illumination to the camera. The mounting bracket can follow the movement of the camera, ensuring that light reaches wherever the camera is positioned. This effectively facilitates nighttime work, ensures safety during nighttime or low-light conditions, and improves work efficiency.

[0004] While the aforementioned device can illuminate the camera using LED lights to complete the inspection work, the LED lights are positioned below the drone, only illuminating the sides and not the top. This makes the drone prone to collisions with external obstacles, such as buildings and cables, during takeoff for power line inspections, leading to damage. To address these shortcomings, we propose a drone-mounted lighting device. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this invention is to provide a drone-mounted lighting device to solve the problems mentioned in the background art.

[0007] 2. Technical Solution

[0008] This invention is achieved through the following technical solution:

[0009] A drone-mounted lighting device includes a mounting frame, a front light fixture, a rear light fixture, a reflector, and a drive assembly.

[0010] Both the front and rear lights are rotatably mounted on the bottom of the mounting frame. The number of reflectors is the same as the sum of the number of the front and rear lights. The reflectors are arranged at an angle. The drive assembly is used to drive the front and rear lights to rotate.

[0011] As an optional solution to the technical solution in this application, there are two front lights and two rear lights, and the installation height of the rear lights on the mounting bracket is lower than that of the front lights.

[0012] As an optional solution to the technical solution in this application, the cross-section of the reflector is arranged in an arc shape.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up a reflector, this application can reflect the light emitted by the lights set at the bottom of the drone upwards, thereby illuminating the airspace above the drone and avoiding collisions with external obstacles and damage caused by insufficient lighting conditions when using the drone for nighttime power inspections.

[0023] 2. By setting a driving component, this application can rotate the rear lamp forward to increase the range and effect of illumination in conjunction with the front lamp; and eccentrically connect the rear lamp to the second driven wheel so that the rear lamp can move closer after rotating forward, increasing the overlap range of illumination and enhancing the lighting effect.

[0024] 3. This application sets a first arc-shaped tooth and a fourth arc-shaped tooth on the first driving wheel and the second driving wheel respectively, and controls the first arc-shaped tooth and the second arc-shaped tooth, and the third arc-shaped tooth and the fourth arc-shaped tooth to not mesh at the same time, so that the rotation of the front lamp can be independently controlled by the rotation of the rear lamp. After the rear lamp rotates forward, the converging position of the light from the front lamp can be adjusted to achieve the adjustment of the lighting position and range, so as to meet the needs of power inspection.

Detailed Implementation

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

[0033] Please see Figure 1 The present invention provides a drone-mounted lighting device, including a mounting frame 1, a front lamp 2, a rear lamp 3, a reflector 4, and a drive assembly 5;

[0034] Both the front light fixture 2 and the rear light fixture 3 are rotatably mounted on the bottom of the mounting frame 1. The number of reflectors 4 is the same as the sum of the number of the front light fixture 2 and the rear light fixture 3. Preferably, there are two front light fixtures 2 and two rear light fixtures 3, and four reflectors 4 are provided. The reflectors 4 are set at an angle.

[0035] The device is mounted on the landing gear of the drone via the mounting bracket 1. In the initial state, the front light 2 and the rear light 3 are tilted to the sides and facing the reflector 4, as shown. Figure 1 As shown. At this time, the light emitted by the front light fixture 2 and the rear light fixture 3 will be reflected upwards by the reflector 4, thereby illuminating the airspace above the drone and preventing it from colliding with aerial obstacles during inspection. The cross-section of the reflector 4 can be set to be arc-shaped, which can disperse the light upwards and increase the illumination area.

[0036] like Figure 3 As shown, a first gear 201 is fixedly connected to the front light fixture 2, and two first gears 201 are meshed together. A second gear 301 is fixedly connected to the rear light fixture 3, and two second gears 301 are meshed together. The drive assembly 5 is used to drive the front light fixture 2 and the rear light fixture 3 to rotate. In this design, the drive assembly 5 only needs to control the rotation of one of the front light fixtures 2 or the rear light fixture 3 to drive the other front light fixture 2 or the rear light fixture 3 to rotate in a mirror image. Finally, the front light fixture 2 and the rear light fixture 3 are adjusted to face forward, as shown. Figure 2 As shown. The installation height of the rear light fixture 3 on the mounting bracket 1 is lower than that of the front light fixture 2, so as to avoid the front light fixture 2 blocking the light emitted by the rear light fixture 3 when the rear light fixture 3 is turned forward.

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

[0038] like Figure 5 As shown, a first arc-shaped clearance groove 5031 is provided on the outer side of the first driving wheel 503, and a first arc-shaped tooth 5032 is fixedly connected inside the first arc-shaped clearance groove 5031. A second arc-shaped tooth 5041 is fixedly connected to 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. A first limiting block 5042 is provided on both sides of the second arc-shaped tooth 5041. The first limiting block 5042 meshes with the first driven wheel 504 and slides in 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 limiting block 5042 will be limited by the first driving wheel 503, keeping the position of the front light fixture 2 fixed and preventing the front light fixture 2 from shaking.

[0039] like Figure 6 As shown, a second arc-shaped clearance groove 5051 is provided on the second driving wheel 505, and a third arc-shaped tooth 5052 is fixedly connected in the second arc-shaped clearance groove 5051. A fourth arc-shaped tooth 5061 is fixedly connected on the second driven wheel 506. The third arc-shaped tooth 5052 and the fourth arc-shaped tooth 5061 are meshed together. Second limiting blocks 5062 are provided on both sides of the fourth arc-shaped tooth 5061, and the second limiting blocks 5062 are fixedly connected to the second driven wheel 506. When the second driving wheel 505 rotates and the third arc-shaped tooth 5052 and the fourth arc-shaped tooth 5061 are not meshed, the second limiting blocks 5062 will maintain the fixed position of the rear lamp 3 under the limiting action of the second driving wheel 505, preventing 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 center and maintain a parallel state, increasing the overlapping illumination range of the two rear lamps 3. Figure 2 As shown.

[0041] Furthermore, the first arc-shaped tooth 5032 does not mesh with the second arc-shaped tooth 5041, and the third arc-shaped tooth 5052 does not mesh with the fourth arc-shaped tooth 5061 simultaneously. This allows the third arc-shaped tooth 5052 and the fourth arc-shaped tooth 5061 to mesh first when the drive motor 501 drives the rotating shaft 502 to rotate. This allows the two rear lamps 3 to rotate forward first and be in a parallel state. Subsequently, the first arc-shaped tooth 5032 meshes with the second arc-shaped tooth 5041, and the front lamp 2 will rotate inward. This facilitates adjusting the position where the light from the front lamp 2 converges, thus successfully completing the power inspection task.
