Description

Technical Field

[0001] This utility model relates to the field of drone payload installation technology, and more specifically, to a rotatable multispectral camera mounting bracket for drone tracking systems. Background Technology

[0002] With the increasing prevalence of drone applications, drone tracking systems play a crucial role in numerous fields, such as security monitoring, agricultural plant protection, and disaster relief. Multispectral cameras, capable of acquiring diverse spectral information, provide richer and more accurate data for these applications, making them an essential component of drone tracking systems. However, existing installation methods for drone multispectral cameras have significant limitations. On one hand, most mounting structures only allow for simple fixed installation or limited rotation in a single direction, lacking flexible adjustment of the shooting angle. In complex and ever-changing real-world application scenarios, this limitation results in the inability to comprehensively capture target information, affecting tracking performance and data quality. On the other hand, some mounting devices with some angle adjustment capabilities have complex and unstable adjustment mechanisms. Therefore, it is essential to develop a reliable and flexible rotatable multispectral camera mounting bracket for drone tracking systems. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a rotatable multispectral camera mounting bracket for a drone tracking system, which can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: The drone tracking system uses a rotatable multispectral camera mounting bracket, which includes a drone shell. U-shaped frames are fixedly installed on both sides inside the drone shell. A column is vertically fixedly installed on the bottom horizontal end face of the U-shaped frame. A spring is sleeved on the column. A motor platform is elastically supported on the top of the spring. A stepper motor is fixedly installed on the top of the motor platform by bolts. The motor shaft of the stepper motor is connected to a multispectral camera mounting platform through a coupling. A multispectral camera is fixedly installed on the bottom of the multispectral camera mounting platform by screws. A linear push rod motor is vertically fixedly installed with the top horizontal end face of the U-shaped frame facing downwards.

[0005] Furthermore, a rubber pad is fixedly installed at the bottom end of the linear actuator motor, and the rubber pad is in close contact with the top surface of the motor platform.

[0006] Furthermore, the top of the column extends through the motor platform, and a clamp is attached to the top of the column.

[0007] Furthermore, the distance from the bottom of the U-shaped frame to the multispectral camera mounting platform is set to 20mm~30mm.

[0008] Furthermore, the multispectral camera mounting platform is disc-shaped, and the top of the multispectral camera mounting platform is integrally formed with a mating shaft, which is sleeved at the bottom of the coupling.

[0009] The beneficial effects of this utility model are as follows: The multispectral camera of this application device is coaxially connected to the stepper motor through a fixed platform and a coupling. By controlling the rotation angle of the stepper motor shaft, the shooting angle of the multispectral camera can be adjusted. The stepper motor is mounted on the motor platform, and the pitch and tilt angle of the motor platform is adjusted through a mechanism composed of a U-shaped frame, a column, a spring, and a linear push rod motor. In conjunction with the rotation of the multispectral camera, a wider shooting and tracking angle of the multispectral camera can be achieved. Attached Figure Description

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figure 1-2As shown, this utility model discloses a rotatable multispectral camera mounting bracket for a drone tracking system, including a drone housing 11. U-shaped frames 6 are fixedly installed on both sides inside the drone housing 11. A column 8 is vertically fixedly installed on the bottom horizontal end face of the U-shaped frame 6. A spring 7 is sleeved on the column 8. A motor platform 4 is elastically supported on the top of the spring 7. A stepper motor 5 is fixedly installed on the top of the motor platform 4 by bolts. The motor shaft of the stepper motor 5 is connected to a multispectral camera mounting platform 2 via a coupling 3. A multispectral camera 1 is fixedly installed on the bottom of the multispectral camera mounting platform 2 by screws. A linear push rod motor 10 is vertically fixedly installed with the top horizontal end face of the U-shaped frame 6 facing downwards. The multispectral camera mounting platform 2 is disc-shaped, and a mating shaft is integrally formed on the top of the multispectral camera mounting platform 2, which is sleeved on the bottom end of the coupling 3.

[0016] Example 1: Stepper motor 5 is connected to the stepper motor driver, which is connected to the PWM output interface of the UAV flight control system via a signal line to receive pulse signals and control the rotation angle; the power line is connected to the UAV's 24V DC power supply to power the motor; the motor's built-in encoder is connected to the flight control system's IO interface to provide real-time feedback on the current axis position; Each push rod motor is equipped with an independent drive module, which is connected to the UAV main control board via a CAN bus. The drive module receives the extension distance command sent by the main control board and controls the extension and retraction of the push rod motor. The push rod motor has a built-in limit switch, which is connected to the main control board via a digital signal line to prevent overextension or overretraction. The U-shaped frame 6 is fixed to the inside of the UAV shell 11 with vertical bolts. The column 8 passes through the top of the motor platform 4 and is clamped with a clamp 9 to prevent the column 8 from separating from the motor platform 4. The bottom end of the linear push rod motor 10 is in flexible contact with the motor platform 4 through a rubber pad. The stepper motor 5 is fixed to the surface of the motor platform 4 with bolts. The motor shaft of the stepper motor 5 passes through the motor platform 4. The bottom end of the motor shaft is fitted with the top of the coupling 3. The shaft at the top of the multispectral camera mounting platform 2 is fitted with the bottom of the coupling 3. The coupling 3 is fastened to the shaft with a pin.

[0017] In the preferred technical solution, the distance between the bottom of the U-shaped frame 6 and the multispectral camera mounting platform 2 is set to 20mm~30mm. Setting the gap can prevent the U-shaped frame 6 from colliding and rubbing against the multispectral camera mounting platform 2.

[0018] In practical use, the stepper motor 5 directly drives the multispectral camera 1 to rotate, which can adjust the shooting range. The four linear push rod motors 10 can be extended and retracted independently. When the two linear push rod motors 10 on the left or right side extend and retract at the same time, the tilt of the motor platform 4 can be controlled. When the two linear push rod motors 10 at the front and rear extend and retract at the same time, the tilt of the motor platform 4 can be controlled. The multispectral camera 1 follows the tilt and pitch of the motor platform 4. Combined with rotation, the shooting range can be increased, which is suitable for shooting and tracking.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
