Description

Technical Field

[0001] This utility model relates to the field of drone mounting structure technology, and in particular to a multispectral camera drone mounting structure. Background Technology

[0002] Multispectral cameras, as the core payload of UAV remote sensing monitoring, have been widely used in precision agriculture, environmental surveys, resource exploration, and disaster assessment. During flight operations, especially in low-altitude, low-speed, or complex terrain environments (such as mountains and forests), UAVs inevitably experience continuous body vibrations and occasional airflow impacts. These vibrations and impacts are directly transmitted to the mounted structure and the multispectral camera it carries, leading to decreased image quality, fatigue damage to equipment components, and even functional failure. This seriously affects the reliability of data acquisition and the service life of the equipment. Therefore, improving the vibration damping performance and environmental adaptability of the mounted structure is a key technical aspect to ensure the successful implementation of UAV multispectral remote sensing missions.

[0003] Currently, most common multispectral camera drone mounting solutions adopt rigid mounting frame structures. At the same time, important components such as camera sensors and lenses are exposed to the outside. In terms of physical protection, most existing devices lack active closed protection designs. Important components such as camera sensors and lenses are exposed to the external environment for a long time during drone take-off, landing, transportation, relocation, or standby. They are extremely susceptible to erosion and damage from sand and dust and accidental bumps. This problem is particularly prominent in harsh operating scenarios such as the field, which significantly reduces the overall reliability and service life of the equipment. The root cause of the above problems is that the existing designs have not taken a system approach that integrates "dynamic operation shock absorption" and "static parking protection" to build a multi-level, all-round protection system. For example, in outdoor operation scenarios such as agricultural plant protection and geological exploration, the frequent vibration and impact caused by complex terrain and variable weather conditions exacerbate the problem of insufficient adaptability of traditional mounting structures.

[0004] Therefore, when used in outdoor operations such as agricultural plant protection and geological exploration, there is a problem of difficulty in improving the overall reliability and environmental adaptability of the mounting structure. Therefore, a multispectral camera drone mounting structure can be designed. When using this multispectral camera drone mounting structure, during the drone's flight, multiple sets of buffer mechanisms can effectively absorb and offset most of the vibration impact, significantly reducing the vibration amplitude transmitted to the protective frame and the internal camera. When the camera finishes working or the drone is in transport or standby mode, the telescopic end of the drive mechanism is activated to push outward, causing the protective end cap to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame. At this time, the protective end cap and the protective frame together form a closed protective shell, completely encapsulating the multispectral camera inside. In summary, the comprehensive buffering and containment design, from the bottom buffer mechanism to the outer protective shell, constructs a multi-level buffer protection system, taking into account both large-scale vibration suppression and local collision protection, improving the overall reliability and environmental adaptability of the mounting structure. Utility Model Content

[0005] In existing technologies, most common multispectral camera drone mounting solutions adopt rigid mounting frame structures. At the same time, most existing devices lack active enclosed protection designs. Important components such as camera sensors and lenses are exposed to the external environment for a long time during drone take-off, landing, transportation, relocation, or standby. They are highly susceptible to erosion and damage from sand and dust and accidental bumps. Therefore, when used in outdoor operation scenarios such as agricultural plant protection and geological exploration, it is difficult to improve the overall reliability and environmental adaptability of the mounting structure.

[0006] The technical solution of this utility model is as follows: a multispectral camera drone mounting structure, including a mounting frame and a mounting base disposed at the bottom front end of the mounting frame. A connecting seat is disposed above the mounting base, a buffer mechanism is disposed between the connecting seat and the mounting base, a protective frame is disposed above the connecting seat, a protective end cap is rotatably disposed at the end of the protective frame, and a driving mechanism is disposed on the outer wall of the protective frame.

[0007] Preferably, when using this multispectral camera drone mounting structure, during drone flight, multiple sets of buffer mechanisms can effectively absorb and offset most of the vibration impact, significantly reducing the vibration amplitude transmitted to the protective frame and the internal camera. When the camera finishes working or the drone is in transport or standby mode, the telescopic end of the drive mechanism is pushed outward, causing the protective end cap to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame. At this time, the protective end cap and the protective frame together form a closed protective shell, completely encapsulating the multispectral camera inside. In summary, the comprehensive buffering and containment design, from the bottom buffer mechanism to the outer protective shell, constructs a multi-level buffer protection system, taking into account both large-scale vibration suppression and local collision protection, improving the overall reliability and environmental adaptability of the mounting structure.

[0008] Preferably, the drive mechanism includes an electrically controlled telescopic rod, a movable rod, and a connector. The electrically controlled telescopic rod is rotatably mounted on one side of the outer wall of the protective frame, and a connector is fixedly mounted on the outer wall of the protective end cover. A movable rod is rotatably mounted between the connector and the telescopic end of the electrically controlled telescopic rod.

[0009] Preferably, one end of the movable rod is rotatably connected to the connector, the other end of the movable rod is rotatably connected to the telescopic end of the electrically controlled telescopic rod, and the fixed end of the electrically controlled telescopic rod is rotatably connected to one side of the outer wall of the protective frame.

[0010] Preferably, the buffer mechanism includes a buffer damper, and multiple sets of buffer dampers are arranged between the connecting seat and the mounting base, with the multiple sets of buffer dampers distributed in a rectangular array.

[0011] Preferably, the fixed end of the buffer damper is fixedly connected to the mounting base, and the telescopic end of the buffer damper is fixedly connected to the connecting seat.

[0012] Preferably, a buffer protective layer is fixedly installed on the inner wall of the protective frame and the protective end cap, and the buffer protective layer is made of elastic foam material.

[0013] Preferably, the mounting base is fixedly connected to the bottom front end of the mounting frame via bolts.

[0014] The beneficial effects of this utility model are: 1. When using this multispectral camera drone mounting structure, during drone flight, multiple buffer mechanisms can effectively absorb and offset most vibration impacts, significantly reducing the vibration amplitude transmitted to the protective frame and internal camera. When the camera finishes working or the drone is in transport or standby mode, the telescopic end of the drive mechanism is pushed outward, causing the protective end cap to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame. At this time, the protective end cap and the protective frame together form a closed protective shell, completely encapsulating the multispectral camera inside. In summary, the comprehensive buffering and containment design, from the bottom buffer mechanism to the outer protective shell, constructs a multi-level buffer protection system, taking into account both large-scale vibration suppression and local collision protection, improving the overall reliability and environmental adaptability of the mounting structure.

[0015] 2. Excellent shock absorption and protection performance: Through the matrix arrangement of multiple sets of buffer dampers, flight vibration and impact are systematically attenuated and isolated, providing a stable working environment for the precision multispectral camera, which helps to ensure data acquisition quality and extend the service life of the equipment.

[0016] 3. Intelligent opening and closing protection mechanism: The linkage mechanism driven by the electronically controlled telescopic rod can realize the automatic and precise opening and closing of the protective end cover, which not only ensures that there is no structural obstruction when the camera is working, but also forms a sealed shell during non-working periods, effectively preventing dust and physical collisions, and adapting to complex field operation environments.

[0017] 4. Modular design and easy maintenance: The bolt-connected mounting base design makes the entire module easy to assemble and disassemble, facilitating the quick installation, disassembly and maintenance of the camera, improving the efficiency and flexibility of UAV mission preparation, and facilitating the rotation of multiple devices and system upgrades.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 2 and Figure 4 This utility model provides an embodiment: a multispectral camera drone mounting structure, including a mounting frame 1, and a mounting base 2 disposed at the bottom front end of the mounting frame 1. A connecting seat 4 is disposed above the mounting base 2, a buffer mechanism is disposed between the connecting seat 4 and the mounting base 2, a protective frame 3 is disposed above the connecting seat 4, a protective end cap 5 is rotatably disposed at the end of the protective frame 3, and a driving mechanism is disposed on the outer wall of the protective frame 3.

[0022] Please see Figure 3 and Figure 4The drive mechanism includes an electrically controlled telescopic rod 6, a movable rod 7, and a connecting piece 8. The electrically controlled telescopic rod 6 is rotatably mounted on one side of the outer wall of the protective frame 3, and the connecting piece 8 is fixedly mounted on the outer wall of the protective end cover 5. The movable rod 7 is rotatably mounted between the connecting piece 8 and the telescopic end of the electrically controlled telescopic rod 6. By activating the electrically controlled telescopic rod 6 in the drive mechanism, its telescopic end retracts, pulling the movable rod 7 to move. One end of the movable rod 7 is hinged to the electrically controlled telescopic rod 6, and the other end is hinged to the connecting piece 8 fixed to the outer wall of the protective end cover 5, thereby pulling the protective end cover 5 to rotate around the hinge axis of the protective frame 3, realizing the smooth unfolding of the end cover and fully exposing the camera lens. In the environment, to ensure unobstructed optical data acquisition, one end of the movable rod 7 is rotatably connected to the connector 8, and the other end of the movable rod 7 is rotatably connected to the telescopic end of the electrically controlled telescopic rod 6. The fixed end of the electrically controlled telescopic rod 6 is rotatably connected to one side of the outer wall of the protective frame 3. When the camera finishes working or the UAV is in transport or standby mode, the telescopic end of the electrically controlled telescopic rod 6 is pushed outward, and the thrust is transmitted to the connector 8 through the movable rod 7, causing the protective end cap 5 to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame 3. At this time, the protective end cap 5 and the protective frame 3 together form a closed protective shell, completely encapsulating the multispectral camera inside.

[0023] Please see Figure 2 and Figure 3 The buffer mechanism includes a buffer damper 9. Multiple sets of buffer dampers 9 are arranged between the connecting seat 4 and the mounting base 2. The multiple sets of buffer dampers 9 are distributed in a rectangular array and work synchronously. Their telescopic ends and fixed ends generate relative displacement between the connecting seat 4 and the mounting base 2, respectively. Through the energy absorption and buffering characteristics of the damper, most of the vibration impact is effectively absorbed and offset, significantly reducing the vibration amplitude transmitted to the protective frame 3 and the internal camera. The fixed end of the buffer damper 9 is fixedly connected to the mounting base 2, and the telescopic end of the buffer damper 9 is fixedly connected to the connecting seat 4. Through the matrix arrangement of multiple sets of buffer dampers 9, flight vibration and impact are systematically attenuated and isolated, providing a stable working environment for the precision multispectral camera, which helps to ensure data acquisition quality and extend the service life of the equipment.

[0024] Please see Figure 1 and Figure 2A buffer protective layer 10 is fixedly installed on the inner wall of the protective frame 3 and the protective end cap 5 respectively. The buffer protective layer 10 is made of elastic foam material. The inner wall of the protective frame 3 and the protective end cap 5 are both fixedly equipped with a buffer protective layer 10 (such as elastic foam). This protective layer can absorb the energy of accidental external collisions and limit the slight displacement of the camera inside the shell, realizing double buffering from the external structure to the internal contact surface. The mounting base 2 is fixedly connected to the bottom front end of the mounting frame 1 by bolt structure. Based on the bolt connection of the mounting base 2, the entire mounting module is easy to disassemble and assemble, which facilitates the quick installation, disassembly and maintenance of the camera, improves the efficiency and flexibility of UAV mission preparation, and is conducive to the rotation of multiple devices and system upgrades.

[0025] When using this multispectral camera drone mounting structure, its working principle is as follows: In actual operation, the mounting structure first securely connects the mounting frame 1 to the designated position of the drone body through a bolt structure, and the mounting base 2 is fixed to the bottom front end of the frame with bolts to achieve rapid installation of the main module.

[0026] The multispectral camera is securely embedded in the inner cavity of the protective frame 3. The frame is connected to the bottom connecting seat 4, and multiple sets of buffer dampers 9 arranged in a rectangular array are provided between the connecting seat 4 and the mounting base 2, forming the core buffer mechanism.

[0027] During the flight of the UAV, vibrations caused by airflow disturbances, motor vibrations, or take-off and landing impacts are transmitted through the mounting frame 1 to the mounting base 2, and then act upwards on the connecting seat 4. At this time, multiple sets of buffer dampers 9 work synchronously, and their telescopic ends and fixed ends generate relative displacements between the connecting seat 4 and the mounting base 2, respectively. Through the energy absorption and buffering characteristics of the dampers, most of the vibration impacts are effectively absorbed and offset, significantly reducing the vibration amplitude transmitted to the protective frame 3 and the internal camera. This provides continuous and stable support for the high-precision multispectral camera in the dynamic flight environment, avoiding imaging blurring or equipment damage caused by vibration.

[0028] During camera use, by activating the electrically controlled telescopic rod 6 in the drive mechanism, its telescopic end retracts, pulling the movable rod 7 to move. One end of the movable rod 7 is hinged to the electrically controlled telescopic rod 6, and the other end is hinged to the connector 8 fixed to the outer wall of the protective end cover 5, thereby pulling the protective end cover 5 to rotate around the hinge axis of the protective frame 3, realizing the smooth unfolding of the end cover, so that the camera lens is fully exposed to the external environment, ensuring unobstructed optical acquisition operations.

[0029] When the camera finishes working or the drone is in transport or standby mode, the telescopic end of the electronically controlled telescopic rod 6 is pushed outward, and the thrust is transmitted to the connector 8 through the movable rod 7, causing the protective end cap 5 to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame 3. At this time, the protective end cap 5 and the protective frame 3 together form a closed protective shell, completely encapsulating the multispectral camera inside.

[0030] To further enhance the protective performance, a buffer protective layer 10 (such as elastic foam) is fixedly provided on the inner wall of both the protective frame 3 and the protective end cap 5. This protective layer can absorb the energy of accidental external collisions and also limit the slight displacement of the camera inside the housing, thus achieving dual buffering from the external structure to the internal contact surface.

[0031] In addition, since the mounting base 2 uses a bolt connection, users can easily remove the bolts when maintenance or equipment replacement is required, separating the entire mounting structure from the drone, which greatly facilitates the removal, placement, and adjustment of the camera or the replacement of the entire module.

[0032] The beneficial effects it produces can be summarized in the following aspects: First, excellent shock absorption and protection performance: Through the matrix arrangement of multiple sets of buffer dampers 9, flight vibration and impact are systematically attenuated and isolated, providing a stable working environment for the precision multispectral camera, which helps to ensure data acquisition quality and extend the service life of the equipment.

[0033] Second, the intelligent opening and closing protection mechanism: using the linkage mechanism driven by the electrically controlled telescopic rod 6, the protective end cover 5 can be opened and closed automatically and precisely, ensuring that there is no structural obstruction when the camera is working, and forming a sealed shell during non-working periods, effectively preventing dust and physical collisions, and adapting to complex field operation environments.

[0034] Third, comprehensive buffering and containment design: from the overall buffering mechanism to the internal protective layer, a multi-level buffering system is constructed, which takes into account both large-scale vibration suppression and local collision protection, improving the overall reliability and environmental adaptability of the mounted structure.

[0035] Fourth, modularity and convenient maintenance: The bolt-connected mounting base 2 design makes the entire module easy to assemble and disassemble, facilitating the quick installation, disassembly and maintenance of the camera, improving the efficiency and flexibility of UAV mission preparation, and facilitating the rotation of multiple devices and system upgrades.

[0036] In summary, this mounting structure, through ingenious mechanical design and electromechanical control, achieves vibration isolation, controllable protection, and convenient integration of the multispectral camera on the UAV platform, significantly enhancing the practicality, durability, and ease of operation of the equipment in applications such as aerial surveying and remote sensing.

[0037] Through the above steps, when using this multispectral camera drone mounting structure, during drone flight, multiple sets of buffer mechanisms can effectively absorb and offset most of the vibration impact, significantly reducing the vibration amplitude transmitted to the protective frame 3 and the internal camera. When the camera finishes working or the drone is in transport or standby mode, the telescopic end of the drive mechanism is activated to push outward, causing the protective end cap 5 to rotate in the opposite direction until it is tightly fitted with the opening edge of the protective frame 3. At this time, the protective end cap 5 and the protective frame 3 together form a closed protective shell, completely encapsulating the multispectral camera inside. In summary, the comprehensive buffering and containment design, from the bottom buffer mechanism to the outer protective shell, constructs a multi-level buffer protection system, taking into account both large-scale vibration suppression and local collision protection, improving the overall reliability and environmental adaptability of the mounting structure.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
