Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a high-altitude emergency searchlight device carried by an unmanned aerial vehicle. Background Art

[0002] Manned aircraft, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. There is no cockpit on the aircraft, but it is equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and transmit digital data to it; drones often need to be equipped with lighting equipment at the bottom for use.

[0003] The patent with publication number CN 210133299 U discloses a high-altitude emergency searchlight device carried by a drone, which includes a body, a fixed seat is provided in the middle of the lower surface of the body, a rotating shaft is rotatably connected to the lower part of the fixed seat, and the rotating shaft is fixedly connected to the right side of the searchlight. A second slide groove is provided on the right side of the lower surface of the body. The device drives the convex mirror to move left and right by setting a first drive motor, thereby adjusting the range of illumination, so that the control of the entire lighting effect is more personalized and simple. However, the searchlight of the device is set in the fixed seat by the rotating shaft, and can only use the second drive motor and the screw rod and other structures to adjust the pitch angle and cooperate with the convex mirror to adjust the lighting range. However, in the process, not only the vertical direction cannot be illuminated, but also when different directions need to be illuminated, the drone itself needs to be adjusted to achieve it, and it is difficult to accurately adjust the multi-directional lighting. For this reason, a high-altitude emergency searchlight device carried by a drone is proposed to solve the problem that the existing drone lighting device is difficult to quickly adjust the lighting direction according to needs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-5, A high-altitude emergency searchlight device mounted on a drone, comprising a mounting plate 1, an adjustment seat 2 is arranged at the bottom of the mounting plate 1, an adjustment slot 3 is provided at the bottom of the adjustment seat 2, two opposite adjustment arms 4 are arranged in the inner cavity of the adjustment slot 3, teeth 5 are arranged on the opposite surfaces of the two adjustment arms 4, a second adjustment slot 6 is arranged at the bottom of the adjustment arm 4, an adjustment block 7 is arranged in the inner cavity of the second adjustment slot 6, a searchlight 8 is fixedly connected to the bottom of the adjustment block 7, a servo motor 9 is arranged inside the adjustment seat 2, a motor 10 is arranged in the inner cavity of the mounting plate 1, a second servo motor 11 is fixedly connected to the front of the right adjustment arm 4, and the adjustment arm 4 and the adjustment block 7 are respectively arranged in the inner cavity of the adjustment slot 3 and the second adjustment slot 6 by a rotating shaft 12. .

[0024] Furthermore, the output shaft of the servo motor 9 passes through the adjustment seat 2 and is fixedly connected to the rotating shaft 12 that fixes the right adjustment arm 4 , and the output shaft of the motor 10 is connected to the adjustment seat 2 .

[0025] Furthermore, the output shaft of the second servo motor 11 passes through the second adjustment slot 6 and is connected to the rotating shaft 12 of the fixed adjustment block 7 .

[0026] Furthermore, there is a large friction force between the adjusting arm 4 and the right adjusting block 7 and the adjusting slot 3 and the second adjusting slot 6 respectively. When the angles of the adjusting arm 4 and the adjusting block 7 are adjusted by using the servo motor 9 and the second servo motor 11, the large friction force between the two and the adjusting slot 3 and the second adjusting slot 6 respectively is used to limit their positions, thereby playing a certain self-locking role.

[0027] Furthermore, a limiting groove 16 is provided in the middle of the outer ring of the mounting plate 1, and an L-shaped block 17 is provided inside the limiting groove 16. The L-shaped block 17 is connected to the adjustment seat 2 by a bolt 18. When the motor 10 drives the adjustment seat 2 to rotate, the L-shaped groove 17 fixed on the adjustment seat 2 by the bolt 18 and the limiting groove 16 on the mounting plate 1 are cooperated to improve the stability of the adjustment seat 2 during rotation, that is, to improve the stability.

[0028] Furthermore, a protective tube 19 is provided on the outer ring of the adjustment seat 2, and the inner cavity of the protective tube 19 is fixedly connected to the limit card plate 13. A limit card slot 15 is provided on the outer ring of the adjustment seat 2. When the drone-mounted high-altitude emergency searchlight device is not in use, the protective tube 19 can be inserted into the limit card slot 15 of the outer ring of the adjustment seat 2 under the action of the internal limit card slot 13, thereby protecting the searchlight device and preventing dust accumulation at the bottom from corroding the interior and shortening the service life of the device.

[0029] Furthermore, the contact surface between the second adjustment slot 6 and the adjustment block 7 in the left adjustment arm 4 is very smooth, the adjustment block 7 that fixes the second adjustment slot 6 in the left adjustment arm 4 can rotate freely, and a counterweight block 14 is provided at the bottom of the outer ring of the left adjustment block 7. When adjusting the angle of the adjustment arm 4, the friction between the adjustment block 7 on which the searchlight 8 is installed at the bottom of the left adjustment arm 4 and the second adjustment slot 6 is small. Therefore, under the action of the counterweight block 14, basically no adjustment is required to irradiate, ensuring that the left searchlight 8 always irradiates vertically downward, thereby increasing the irradiation mode and improving the applicability of this type of high-altitude emergency searchlight device.

[0030] Working principle: When using this drone-mounted high-altitude emergency searchlight device, install the device on the bottom of the drone using the mounting plate 1. When the required position needs to be illuminated, the servo motor 9, the rotating shaft 12 and the teeth 5 are used to drive the adjustment arm 4 in the adjustment slot 3 to rotate to the required angle, and then the second servo motor 11 is used to drive the searchlight 8 at the bottom of the adjustment block 7 in the second adjustment slot 6 on the right to rotate to the lighting angle. Finally, there is no need to adjust the drone. The motor 10 can drive the adjustment seat 2 to adjust the lighting direction, the secondary pitch angle adjustment and rotation to ensure the lighting needs, which solves the problem that the existing drone lighting device is difficult to quickly adjust the lighting direction according to needs.
