[0002] As is well known, with the rapid development of drone technology, its application in emergency rescue, security monitoring, power line inspection, fire reconnaissance and other fields is becoming increasingly widespread. Especially at night or in low light environments, drones equipped with searchlights have become important tools for performing tasks such as lighting, searching and tracking.
[0003] Some existing searchlight brackets only support angle adjustment in a fixed angle or a single direction, which greatly limits the illumination coverage. For example, when it is necessary to illuminate targets at different heights, if the searchlight can only work at a fixed pitch angle, the entire drone must be moved to adjust the illumination direction. This method is not only inefficient, but also increases the difficulty of operation. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a drone searchlight bracket, which has the following features:
[0017] Beneficial effects:
[0018] This drone searchlight bracket, through its adjustable height mechanism, connects the outputs of two dual-head motors to the left and right drive shafts respectively, synchronously driving the searchlight body to adjust its pitch. This avoids the tilting and swaying problems that may occur with single-sided drive, improving overall operational stability and reliability. It supports a wide range of vertical angle adjustments for the searchlight body (such as 30° upward, 45° downward, etc.), allowing operators to flexibly adjust the illumination angle according to the actual terrain or mission requirements, achieving precise illumination of specific target areas. Using a servo motor as the power source, it has rapid start-stop and precise positioning capabilities, enabling quick response to remote control commands and improving the system's real-time operability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-4A drone searchlight bracket includes a drone body 1, a mounting base 2, an adjusting base 3, a connecting base 4, a fixing base 5, a searchlight body, a vertical angle adjustment device, and a horizontal adjustment device. The mounting base 2 is mounted on the top of the drone body 1 via a connector. The adjusting base 3 is mounted on the top wall of the mounting base 2. The connecting base 4 is mounted on the top of the adjusting base 3 via the horizontal adjustment device. The fixing base 5 is mounted on the top wall of the connecting base 4. The searchlight body is mounted on the left and right ends of the fixing base 5 via the vertical angle adjustment device. In this embodiment, during use, the mounting base 2 is first fixed to the top of the drone body 1 via a connector (the connector can be a bolt), ensuring that the mounting base 2 is firmly attached to the drone body 1. The adjusting base 3 is then correctly installed on the top wall of the mounting base 2. Within the adjusting base 3, the operator remotely controls the searchlight. The device or drone control system sends adjustment commands to the drone body, which can achieve horizontal rotation adjustment of the connecting seat 4 relative to the adjusting seat 3 through the horizontal adjustment device. This step allows the searchlight body to be adjusted horizontally by 360 degrees as needed to cover a wider area or a specific target point. The left and right ends of the fixed seat 5 are connected to the searchlight body through the up and down angle adjustment device, allowing the searchlight body to be adjusted vertically. In this way, the illumination angle of the searchlight can be finely adjusted according to actual needs to adapt to different terrains or mission requirements. After the drone body 1 is positioned at the target location, this design supports all-round angle adjustment. Whether in the horizontal or vertical direction, it can flexibly cope with the lighting needs of various complex environments, achieve all-round lighting without blind spots, meet diverse mission requirements, and improve the drone's adaptability and work efficiency in complex environments.
[0027] Preferably, in this embodiment, the vertical angle adjustment device includes a dual-head motor 6 and drive shafts 7. The dual-head motor 6 is installed inside the fixed base 5, and drive shafts 7 are installed at both ends of the dual-head motor 6. The ends of the two sets of drive shafts 7 away from the dual-head motor 6 are fixedly connected to the side wall of the searchlight body. The operator sends an angle adjustment command to the drone body through a remote control or drone control system. This command is transmitted to the dual-head motor 6 installed inside the fixed base 5. The dual-head motor 6 starts working according to the received signal, and its left and right output shafts rotate synchronously. The drive shafts 7 on both sides of the dual-head motor 6 rotate accordingly and transmit power to the ends fixedly connected to the side wall of the searchlight body. The synchronous movement of the drive shaft 7 drives the searchlight body to swing up and down around the fixed base 5. As needed, the operator can precisely set the pitch angle of the searchlight body (e.g., tilting 30° upward from the horizontal or 45° downward) to achieve illumination coverage of a specific area. When the target angle is reached, the dual-head motor 6 automatically enters the holding state to maintain the current angle, ensuring stable illumination of the searchlight and preventing it from shifting due to flight vibrations. Using one dual-head motor 6 to drive two drive shafts 7 simultaneously saves space and weight, making it very suitable for the lightweight design requirements of UAV platforms. The dual-point support structure enhances the overall stability and can withstand the weight of the searchlight body, making it suitable for mounting high-power LED searchlights.
[0028] Preferably, in this embodiment, the horizontal adjustment device includes a cavity 8, a rotating shaft 9, a large gear 10, a small gear 11, and a drive motor 12. The cavity 8 is formed inside the adjustment seat 3, and the rotating shaft 9 is rotatably installed inside the cavity 8. The top end of the rotating shaft 9 passes through the top wall of the adjustment seat 3 and is fixedly connected to the top wall of the connecting seat 4. The large gear 10 is sleeved on the outer wall of the rotating shaft 9. The drive motor 12 is installed on the bottom wall of the cavity 8, and the small gear 11 is installed on the top end of the drive motor 12. The small gear 11 and the large gear 10 are meshed together. When the operator sends a horizontal rotation command through a remote control or drone control system, the command will trigger the drive motor 12 to start working. After the drive motor 12 starts, it drives the small gear 11 at its top to rotate. Since the small gear 11 and the large gear 10 are meshed together... The gears 10 mesh, so the rotation of the pinion 11 drives the large gear 10 to rotate synchronously. The rotation of the large gear 10 directly causes the shaft 9 to rotate around its axis. Since the top of the shaft 9 is fixed to the connecting seat 4, the connecting seat 4, together with the fixed seat 5 above and the searchlight body, will rotate horizontally together. According to the operation command, the drive motor 12 can precisely control the rotation angle of the shaft 9, thereby realizing any angle adjustment of the searchlight body in the horizontal direction. This allows the searchlight to cover a wider area or focus on a specific target point after the UAV body 1 is positioned at the target location. Whether in a static scene or a dynamic environment, this horizontal adjustment device can provide flexible angle adjustment function, greatly expanding the application range of UAV searchlights, such as night search and rescue, disaster assessment, and large-scale event site monitoring.
[0029] Preferably, in this embodiment, both the dual-head motor 6 and the drive motor 12 are servo motors. The servo motor has a feedback control system, which can precisely control the rotation angle. This means that both the vertical angle adjustment device and the horizontal adjustment device can achieve very fine adjustments to ensure that the searchlight points to the required precise position.
[0030] Preferably, in this embodiment, the connecting base 4 is equipped with an energy storage battery 13. The energy storage battery 13 provides an independent power source for the servo motors in the vertical angle adjustment device and the horizontal adjustment device, as well as the searchlight body. This means that even if the UAV's battery is low or malfunctions, the searchlight system can still operate independently for a period of time, improving the system's reliability and autonomy.
[0031] Preferably, in this embodiment, a shock-absorbing pad is provided between the mounting base 2 and the UAV body 1. The shock-absorbing pad can effectively absorb and buffer the vibrations generated during flight, preventing these vibrations from being directly transmitted to the searchlight and other precision components. This is crucial for protecting high-precision electronic components, optical instruments, etc. from damage.
[0032] Preferably, in this embodiment, the searchlight body includes an LED light group 14 and a condenser 15. The output end of the drive shaft 7 is fixedly connected to the side wall of the condenser 15. The LED light group 14 is installed inside the condenser 15. The design of the condenser 15 can effectively collect and concentrate the light emitted by the LED light group 14 to form a strong and concentrated beam, which is suitable for long-distance illumination or high-brightness illumination of specific areas. The LED light group 14 usually has good light distribution characteristics. Combined with the function of the condenser 15, it can achieve a bright and uniform lighting effect, avoiding the hot spots or shadow problems that may occur with traditional light sources. Directly installing the LED light group 14 inside the condenser 15 not only simplifies the overall design but also reduces unnecessary space occupation, which helps to reduce the load of the UAV body 1 and improve flight efficiency.
[0033] Preferably, in this embodiment, the LED light group 14 supports brightness adjustment function. The operator can send brightness adjustment commands to the UAV body 1 through a remote control, ground control station or other control system. These commands contain specific brightness levels or adjustment range information. After receiving the brightness adjustment command, the control system will convert it into a corresponding electrical signal or pulse width modulation (PWM) signal to control the working mode of the LED driving circuit. The LED driving circuit adjusts the current intensity or voltage level supplied to the LED light group 14 according to the received signal. For systems that support PWM dimming, the driving circuit will change the duty cycle to achieve brightness changes. For example, increasing the duty cycle can increase the brightness, while decreasing the duty cycle can decrease the brightness. Different task scenarios and time points may have different requirements for light intensity. The adjustable brightness function enables the searchlight to adapt to various situations such as detailed observation under low light conditions and rapid search under high light conditions, thereby enhancing the application range of the equipment.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
