Description

Technical Field

[0001] The present invention relates to the technical field of smart agriculture, and in particular to an intelligent pesticide-spreading drone for smart agriculture. Background Art

[0002] With the rapid development of modern agriculture, the application of drone technology in the agricultural field has become more and more extensive, especially in the application of pesticide spraying operations. The traditional method of pesticide spraying relies on manual operation or ground mechanical equipment, and there are many problems such as low spraying efficiency, serious drug waste, and great impact on the environment. At the same time, in large areas of farmland or complex terrain conditions, the operation of traditional pesticide spraying equipment has limitations, and it is difficult to achieve precise spraying and uniform coverage. In addition, during the manual spraying of pesticides, operators are exposed to the environment of chemical agents, which is easy to cause harm to human health.

[0003] In recent years, agricultural drones have been gradually used in pesticide spraying operations due to their flexibility, high efficiency and precise control. However, the existing agricultural drone technology still has certain shortcomings.

[0004] First of all, the existing atomization technology has a weak ability to handle high-viscosity pesticides, the atomization effect is not ideal, and uneven spraying is prone to occur.

[0005] In addition, due to the lack of effective shock-absorbing devices when landing, the landing impact of existing drones will cause damage to the drone structure and its precision components, affecting the service life and operational stability of the equipment.

[0006] To this end, those skilled in the art provide a smart pesticide spraying drone for smart agriculture to solve the problems raised in the above background technology. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides an intelligent pesticide-spraying drone for smart agriculture, which solves the problems of low energy efficiency during pesticide spraying, poor atomization effect of high-viscosity pesticides, and impact vibration caused to the equipment during landing in the prior art.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: an intelligent pesticide spreading drone for smart agriculture, comprising:

[0009] A mounting frame, which is composed of multiple aluminum alloy plates bolted together and is used to connect other components to provide connection strength;

[0010] A storage component, which is located on the top of the mounting frame and is used to store pesticides and provide a source of pesticides for spraying;

[0011] An intelligent control component, which is located on one side of the storage component and is used to control the lift of the drone and the atomization speed to achieve a balance;

[0012] The atomization component is located on one side of the storage component and uses the power of the intelligent control component to atomize the pesticide passing through;

[0013] There are multiple groups of shock-absorbing components, located on one side of the mounting frame, which are used to reduce the vibration impact of the drone touching the ground on other components;

[0014] The atomization assembly also includes a nozzle, which is arranged on one side of the storage assembly through a plurality of rivets. The nozzle is arranged on one side of the storage assembly, and a turntable and a first gear are rotatable on the top. When the turntable is driven to rotate by means of the intelligent control assembly, the first gear is driven to rotate in multiple directions in a forward and reverse manner through engagement stages, so as to cooperate with the rotating rod and the contact rod connected to the first gear to fully contact the pesticide transported by the second conveying pipe, and realize atomization after the pesticide is dispersed.

[0015] Preferably, the storage assembly comprises a pesticide box, a plurality of the pesticide boxes are mounted on the top of the mounting frame, a feed port is provided at one end thereof, and a plurality of first conveying pipes are provided at the other end thereof, for conveying the pesticide to the filling component by gravity.

[0016] Preferably, the filling component includes a shaft rod, which is installed at the four corners of the inner cavity of the mounting frame and fixed to the outer wall of a control panel fixed in the inner cavity of the mounting frame. A plurality of motors are installed in the inner cavity of the control panel. The motors are used to drive the auger to rotate in the inner cavity of the shaft rod, so as to transfer the pesticide transported by the first delivery pipe to the atomization assembly.

[0017] Preferably, the intelligent control component includes a controller, in which a control component is installed for controlling the start and stop of fan blades connected to multiple electrically connected motors, and multiple solid-state batteries are installed on the top of the mounting frame for powering components that require power.

[0018] Preferably, one side of the fan blade is connected to the center of the turntable, and is used to synchronously drive the half gear and the turntable to rotate synchronously, and periodically meshes with the first gear through the semi-meshing state of the inner rack set in the inner cavity of the turntable and the half gear.

[0019] Preferably, the shock-absorbing assembly includes a mounting plate, and a plurality of the mounting plates are bolted to the bottom of the mounting frame, and a plurality of connecting rods are respectively connected to the bottom ends thereof, for cooperating with the contact between the middle block at the bottom of the mounting plate and the first buffer rod to realize step-by-step buffering. The first buffer rod is fixed to one side of the telescopic block, and the outer wall is sleeved with a middle block for connecting to a track plate for limiting positioning, and a second buffer rod is symmetrically arranged in the inner cavity of the track plate.

[0020] Preferably, one end of the plurality of connecting rods is connected to two sides of the telescopic block.

[0021] Preferably, a speed control system is installed inside the intelligent control component, and the speed control system includes a flight control module and an intelligent speed distribution algorithm module.

[0022] Preferably, the flight control module comprises:

[0023] The inertial measurement unit and GPS module are used to obtain the UAV's flight attitude, altitude, speed and position information in real time, and to feed back the flight status data to the intelligent speed distribution algorithm module;

[0024] The rotor speed control unit is used to receive the speed adjustment instruction provided by the intelligent speed distribution algorithm module to adjust the speed of each rotor to maintain the stable flight of the UAV.

[0025] Preferably, the intelligent speed distribution algorithm module includes a data processing unit for receiving flight attitude data, load data and environmental data from the flight control module, and calculating the speed distribution of the rotor in combination with the pesticide spraying requirements;

[0026] The priority control unit gives priority to ensuring lift according to the stability of the current flight state and the demand for pesticide spraying, and provides more rotor power to the pesticide atomization device when the flight is stable;

[0027] The intelligent speed distribution algorithm module uses a proportional-integral-differential control algorithm to dynamically adjust the rotor speed to maintain a real-time balance between the flight and spraying systems.

[0028] Working principle: At startup, the flight control module of the drone obtains flight attitude, altitude, speed and position information in real time through the inertial measurement unit and GPS module. Based on this data, the flight control module controls the rotor speed control unit and adjusts the rotor speed to provide the required lift so that the drone can take off smoothly. The attitude adjustment and speed control during the flight are automatically performed by the flight control module to ensure the stability of the drone in the air and the accuracy of the path.

[0029] When the drone reaches the target flight altitude and enters the operating area, the intelligent speed distribution algorithm module in the intelligent control component starts to work. This module receives the flight status data, load information and environmental conditions provided by the flight control module, and calculates the optimal speed distribution of the rotor based on this data.

[0030] The intelligent speed distribution algorithm module takes into account both the flight lift requirements and the atomization requirements of pesticides. When the drone is flying stably, part of the rotor speed is used to maintain flight stability, and the other part of the rotor speed is provided to the atomization device through the speed distribution algorithm to achieve atomization spraying of pesticides.

[0031] The pesticide in the storage assembly enters the first delivery pipe by gravity, and is then driven by the auger in the filling component and delivered to the atomizing assembly through the second delivery pipe. The atomizing assembly delivers the pesticide from the storage assembly to the rotating turntable through the spray pipe.

[0032] When the turntable is driven to rotate by the power controlled by the intelligent control component, the turntable meshes with the first gear, driving the gear and the connected rotating rod and contact rod to rotate in multiple directions. The pesticide contacts the rotating rod and the contact rod in multiple directions, and the kinetic energy during the rotation process is used to scatter the pesticide, and finally achieve atomization spraying. The whole process ensures the stability and uniformity of the atomization effect by precisely controlling the rotor speed.

[0033] During the spraying operation, the drone flight control module continuously monitors the flight status and feeds this information back to the intelligent speed distribution algorithm module. When the amount of pesticide decreases, the load is reduced, and the algorithm module automatically reduces the lift demand and allocates more rotor power to the atomization device to optimize the atomization effect.

[0034] In addition, the flight control module adjusts the rotor speed in real time to cope with possible changes in flight attitude, ensuring that the drone always maintains a stable flight state.

[0035] When the pesticide spraying task is completed or the battery power is low to the warning level, the intelligent speed distribution algorithm module will give priority to stopping the pesticide atomization equipment and use all the speed resources of the rotor for lift and return flight. The flight control module guides the drone to return based on GPS positioning and automatically plans the optimal path.

[0036] When the drone approaches the ground, the flight control module will gradually reduce the rotation speed of the rotor to keep the descent speed of the drone within a safe range. The shock absorbing component plays a role when the drone touches the ground.

[0037] The shock-absorbing assembly includes a mounting plate, multiple connecting rods, a first buffer rod, and a second buffer rod. When the drone touches the ground, the connecting rod at the bottom of the mounting plate first touches the ground, and the first buffer rod and the middle block absorb the impact force step by step through the connecting rod to reduce the impact from the ground. Subsequently, the second buffer rod in the track plate further buffers the vibration to ensure that other parts of the drone will not be damaged by vibration during the landing process. The telescopic block in the shock-absorbing assembly makes the landing process smoother by buffering step by step, ensuring that the drone lands safely.

[0038] The present invention provides an intelligent pesticide spreading drone for smart agriculture, which has the following beneficial effects:

[0039] 1. The present invention uses an intelligent speed distribution algorithm to accurately control the speed of the rotor, which is not only used to provide the UAV's flight lift, but also distributes part of the rotor power to the atomization component. The turntable and gear system in the atomization component are driven to rotate using the rotor power, and the contact rod and the rotating rod are used to disperse the pesticide in multiple directions to achieve atomization treatment. This design can make full use of the UAV's rotor airflow and power, avoid additional atomization power systems, and improve the system's energy efficiency and operating efficiency.

[0040] 2. The present invention uses an intelligent speed distribution algorithm module to dynamically adjust the speed distribution of the rotor according to the flight status, load changes and pesticide spraying requirements of the drone. The flight control module monitors the flight attitude, speed, load and environmental data in real time to ensure that the drone can maintain a stable flight attitude under different operating environments, and when the flight is stable, the excess power is distributed to the atomization system. Through the proportional-integral-differential control algorithm, the real-time adjustment of the speed distribution ensures the balance between flight stability and spraying efficiency.

[0041] 3. The present invention uses the buffer assembly to absorb the impact force step by step through the mounting plate, connecting rod, first buffer rod, second buffer rod and middle block, etc., to ensure the stability of the UAV during landing. This design not only reduces the loss of the UAV structure, but also effectively protects the storage assembly, spraying assembly and intelligent control system, and prolongs the service life of the equipment.

DETAILED DESCRIPTION

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] An embodiment of the present invention provides an intelligent pesticide spreading drone for smart agriculture, comprising:

[0053] Please refer to the attached Figure 1 -Attached Figure 3 , a mounting frame 1, which is composed of a plurality of aluminum alloy plates bolted together, and is used to connect other components to provide connection strength;

[0054] Specifically, the mounting frame 1 is composed of a plurality of aluminum alloy plates bolted together, serving as the basic support structure of the drone, and is used to connect and support various components. The aluminum alloy plates are selected for their light weight and high strength, which can provide sufficient bearing capacity while reducing the impact on the overall weight of the drone and improving flight efficiency. The aluminum alloy plates are fixed by bolts to ensure the structural stability of the mounting frame 1, while facilitating subsequent maintenance and replacement. The plates are connected by precisely designed bolted interfaces to ensure that they do not loosen or shift during flight, thereby improving the durability and vibration resistance of the equipment.

[0055] A storage assembly is installed on the top of the mounting frame 1, and a plurality of pesticide boxes 2 are firmly connected to the mounting frame 1 by buckles and bolts for storing pesticides. A first delivery pipe 5 is connected to the bottom of the pesticide box 2 to deliver the pesticide to the atomization assembly by gravity. The storage assembly is fixed on the top of the mounting frame 1, and the design is reasonable to ensure the stability of the storage system during flight vibration and operation.

[0056] An intelligent control component is installed on one side of the mounting frame 1. The controller 4 is installed on the side wall by bolts and is responsible for controlling the flight posture of the drone and the power distribution of the atomization component. The controller 4 contains multiple motors 10, which drive the first gear 17, the rotating rod 19 and the contact rod 20 through the rotating disk 15 to realize the atomization spraying of the pesticide.

[0057] The bottom of the mounting frame 1 is fixed with a buffer assembly by bolting, and the buffer assembly includes a mounting plate 21, a connecting rod 27 and a first buffer rod 23. The buffer system transmits the impact force step by step through these components. When the drone touches the ground, the connecting rod 27 first touches the ground, and then the first buffer rod 23 and the second buffer rod 26 work together through the track plate 24 and the middle block 22 to effectively absorb the ground impact, ensuring that the impact of vibration on other components is reduced when the drone lands.

[0058] Please refer to the attached Figure 3 -Attached Figure 4 , a storage component, which is located on the top of the mounting frame 1 and is used to store pesticides to provide a source of pesticides for spraying; the storage component includes a pesticide box 2, multiple pesticide boxes 2 are installed on the top of the mounting frame 1, one end of which is provided with a feed port, and the other end is provided with multiple first conveying pipes 5, which convey the pesticides to the filling components by gravity.

[0059] The filling component includes a shaft rod 7, which is installed at the four corners of the inner cavity of the mounting frame 1 and fixed to the outer wall of a control panel 6 fixed in the inner cavity of the mounting frame 1. A plurality of motors 8 are installed in the inner cavity of the control panel 6. The motor 8 is used to drive the auger 9 to rotate in the inner cavity of the shaft rod 7, so as to transfer the pesticide transported by the first delivery pipe 5 to the atomization assembly.

[0060] Specifically, the storage assembly is located at the top of the mounting frame 1, and is mainly used to store pesticides and provide a source of pesticides for the spraying process. The storage assembly includes a plurality of pesticide boxes 2, which are fixed to the top of the mounting frame 1 by bolts and a snap-on structure. A feed port is provided at one end of each pesticide box 2 for adding pesticides, and a plurality of first delivery pipes 5 are connected to the other end. The delivery pipes flow the pesticides naturally to the filling components below through gravity, thereby realizing automatic delivery of the pesticides without the need for additional power assistance. This structural design ensures that the drone can continuously and stably deliver pesticides when performing tasks.

[0061] The filling component is responsible for transferring the pesticide from the storage component to the atomization component. The filling component includes a shaft 7, which is installed at the four corners of the inner cavity of the mounting frame 1 and is supported and fixed by a control panel 6 fixed in the inner cavity of the mounting frame 1. The control panel 6 is installed in the inner cavity of the mounting frame 1 and is closely matched with the filling component and related components to ensure that the filling component remains stable during flight. The inner cavity of the control panel 6 is equipped with multiple motors 8, which are used to drive the auger 9 to rotate. The auger 9 is installed in the inner cavity of the shaft 7 and is driven by the motor 8 to rotate inside the shaft 7. Through the rotation of the auger 9, the pesticide from the first delivery pipe 5 is gradually transferred and pushed into the atomization component to prepare for subsequent atomization processing. Such a mechanical transmission design can effectively improve the delivery efficiency of pesticides and avoid poor delivery due to insufficient gravity or pipeline blockage.

[0062] Please refer to the attached Figure 1 -Attached Figure 2 , the intelligent control component is located on one side of the storage component, and is used to control the lift of the drone and the atomization speed to achieve a balance; the intelligent control component includes a controller 4, and a control component is installed inside the controller 4, which is used to control the start and stop of the fan blades 11 connected to the multiple electrically connected motors 10, and multiple solid-state batteries 3 are installed on the top of the mounting frame 1, which are used to power the components of the required power supply. One side of the fan blade 11 is connected to the center of the turntable 15, and is used to synchronously drive the half gear 18 and the turntable 15 to rotate synchronously, and the inner rack 16 set in the inner cavity of the turntable 15 is in a semi-meshing state with the half gear 18, and periodically meshes with the first gear 17.

[0063] Specifically, the intelligent control component is located on one side of the storage component, and is mainly used to control the balance between the lift and atomization speed of the drone to ensure flight stability and efficient atomization spraying of pesticides. The component includes a controller 4, which is mounted on the mounting frame 1 of the drone and controls the core operations of the entire system through electrical connections. Multiple control components are installed inside the controller 4, which are responsible for managing and regulating multiple motors 10 electrically connected to it. These motors 10 directly drive the fan blades 11 connected thereto to control the start and stop of the fan blades 11, realize the power output of the rotor, and thus provide the drone with flight lift.

[0064] A plurality of solid-state batteries 3 are also installed on the top of the mounting frame 1, which provide power to all components that require power, such as the intelligent control components, the rotor motor 10, the atomization device, etc. The design of the solid-state battery 3 not only provides efficient and stable power output, but also extends the flight time of the drone, ensuring the power requirements of the drone during long-term pesticide spraying operations.

[0065] One side of the fan blade 11 is connected to the center of the turntable 15 by a precise connection method, and the turntable 15 is rotated by the drive of the intelligent control component. The inner cavity of the turntable 15 is designed with an inner rack 16, which forms a semi-meshing state with the turntable 15 through a half gear 18. When the turntable 15 rotates, the half gear 18 periodically meshes with the first gear 17, thereby driving the first gear 17 to rotate synchronously. Through this transmission structure, the fan blade 11 not only provides flight lift, but also drives the synchronous operation of the turntable 15, the half gear 18 and the first gear 17 through mechanical transmission, providing additional power support for the atomization component to ensure uniform atomization of the pesticide. This design realizes the effective linkage between the power of the fan blade 11 and the atomization device, thereby optimizing the energy efficiency and operation effect of the drone.

[0066] The intelligent control component is equipped with a speed control system, which includes a flight control module and an intelligent speed distribution algorithm module. The flight control module includes:

[0067] The inertial measurement unit and GPS module are used to obtain the UAV's flight attitude, altitude, speed and position information in real time, and to feed back the flight status data to the intelligent speed distribution algorithm module;

[0068] The rotor speed control unit is used to receive the speed adjustment instruction provided by the intelligent speed distribution algorithm module to adjust the speed of each rotor to maintain the stable flight of the UAV.

[0069] Specifically, the intelligent control component is equipped with a speed control system, the core function of which is to coordinate the flight stability of the drone and the atomization requirements of pesticide spraying. The speed control system is mainly composed of a flight control module and an intelligent speed distribution algorithm module, which work closely together to ensure that the drone can maintain stable flight and optimize the atomization effect during the operation.

[0070] The flight control module contains an inertial measurement unit (IMU) and a GPS module, which are used to collect the UAV's flight attitude, altitude, speed and position information in real time. The inertial measurement unit monitors the UAV's attitude changes, including flight state parameters such as pitch angle, roll angle and yaw angle, while the GPS module provides accurate altitude and position information. After these real-time data are collected, they are immediately fed back to the intelligent speed distribution algorithm module for analysis and processing.

[0071] Another important part of the flight control module is the rotor speed control unit. This unit is responsible for dynamically adjusting the speed of each rotor according to the instructions of the intelligent speed distribution algorithm module. The intelligent speed distribution algorithm module calculates the optimal speed distribution of the current rotor by analyzing the flight status data to ensure that the drone always maintains stable flight under different load and environmental conditions. The rotor speed control unit can accurately adjust or quickly adjust according to the different speed requirements of each rotor, so as to effectively deal with wind speed changes, load changes and other situations that may be encountered during the flight, and ensure the stability and flight safety of the drone.

[0072] In addition, after receiving the data from the flight control module, the intelligent speed distribution algorithm module calculates the optimal distribution plan of rotor power between flight and atomization based on the needs of pesticide spraying. When the drone needs more lift, the algorithm will prioritize the allocation of rotor power to maintain flight stability; when the flight is stable, the system will transfer part of the rotor power to the atomization component to ensure atomization efficiency and spraying effect. The design of this speed control system ensures intelligent and precise control of the drone during flight and spraying operations.

[0073] Please refer to the attached Figure 5 -Attached Figure 7, an atomization component, which is located on one side of the storage component, and uses the power of the intelligent control component to atomize the pesticide passing through; the atomization component also includes a nozzle 13, which is arranged on one side of the storage component through a plurality of rivets 14. The nozzle 13 is arranged on one side of the storage component, and a turntable 15 and a first gear 17 are rotated on the top. When the turntable 15 is driven to rotate by the intelligent control component, the first gear 17 is driven to rotate in multiple directions in a forward and reverse manner through engagement stages, so as to cooperate with the rotating rod 19 and the contact rod 20 connected to the first gear 17 to fully contact the pesticide transported by the second conveying pipe 12, and break it up to achieve atomization.

[0074] Specifically, the atomizing assembly is installed on one side of the storage assembly, and its main function is to use the power of the intelligent control assembly to atomize the pesticide passing through the delivery pipeline, thereby achieving efficient spraying. One of the core components of the atomizing assembly is the nozzle 13, which is firmly fixed to one side of the storage assembly by a plurality of rivets 14. The rivets 14 provide a stable connection, ensuring that the nozzle 13 can work stably without displacement or loosening during flight vibration and long-term operation.

[0075] A turntable 15 is connected to the top of the nozzle 13, and the turntable 15 rotates under the drive of the intelligent control component. The turntable 15 is connected to the first gear 17 through an internal power transmission mechanism. The rotation of the turntable 15 drives the internal meshing mechanism, so that the first gear 17 rotates in multiple directions in the forward and reverse directions during the rotation process. This design allows the gear to change direction during the rotation process, ensuring the comprehensiveness and uniformity of the atomization.

[0076] The first gear 17 is further connected to the rotating rod 19, and the rotating rod 19 transmits power to the contact rod 20 by rotating. The contact rod 20 fully contacts the pesticide delivered from the second delivery pipe 12 during the rotation process. Since the contact rod 20 cooperates with the rotating gear, the pesticide flowing through the delivery pipe can be dispersed in multiple directions. Through this rotation and dispersion method, the atomization component can effectively atomize high-viscosity pesticides to generate uniform fine droplets.

[0077] This design utilizes the mechanical power of rotational motion to achieve full atomization of pesticides, and precisely controls the rotation speed and power transmission through intelligent control components, so that the atomization effect is always maintained at the best state. The entire system ensures continuous atomization of pesticides through the multi-directional rotation of gears and turntable 15, and can adapt to the requirements of different pesticide viscosities and flow rates, thereby providing more accurate and uniform pesticide spraying for crops.

[0078] Please refer to the attached Figure 8The shock absorbing components, which are in multiple groups, are located on one side of the mounting frame 1 and are used to reduce the vibration impact of the drone touching the ground on other components; the shock absorbing components include a mounting plate 21, and multiple mounting plates 21 are bolted to the bottom of the mounting frame 1, and multiple connecting rods 27 are connected to the bottom ends thereof, which are used to cooperate with the contact between the middle block 22 at the bottom of the mounting plate 21 and the first buffer rod 23 to achieve step-by-step buffering. The first buffer rod 23 is fixed to one side of the telescopic block 25, and the outer wall is provided with the middle block 22, which is used to connect the track plate 24 for limiting. The inner cavity of the track plate 24 is symmetrically provided with the second buffer rod 26. One end of the multiple connecting rods 27 is connected to both sides of the telescopic block 25.

[0079] Specifically, the design of the shock absorbing assembly is used to reduce the vibration impact on the mounting frame 1 and other components when the drone lands. There are a total of multiple groups of shock absorbing assemblies, which are installed on one side and the bottom of the mounting frame 1. Each group of shock absorbing assemblies includes a mounting plate 21, and multiple mounting plates 21 are bolted to the bottom of the mounting frame 1. The design of the mounting plate 21 ensures that the shock absorbing assembly is firmly connected to the mounting frame 1, and can withstand the impact force when the drone lands.

[0080] The bottom end of the mounting plate 21 is connected to a plurality of connecting rods 27 through a connecting structure, and these connecting rods 27 are used to disperse and transmit the impact force when touching the ground. One end of the connecting rod 27 is fixed to both sides of the telescopic block 25, and the telescopic block 25 can perform a certain range of telescopic movement along the direction of the mounting plate 21 when impacting, absorb part of the impact force and achieve effective shock absorption through a step-by-step buffer mechanism.

[0081] The connecting rod 27 cooperates with the movement of the telescopic block 25 and contacts the middle block 22. The middle block 22 is sleeved on the outer wall of the first buffer rod 23 and cooperates with the first buffer rod 23 to gradually absorb the impact energy from the connecting rod 27. The first buffer rod 23 is designed to withstand most of the initial impact force when the drone lands, and transmits the impact force to the middle block 22 through telescopic movement.

[0082] In order to further enhance the buffering effect, the middle block 22 is connected to the track plate 24, and the inner cavity of the track plate 24 is symmetrically provided with a second buffer rod 26. The second buffer rod 26 interacts with the middle block 22 and the track plate 24 through the inner cavity limit structure to provide an additional buffer layer. This design ensures that in the case of a large impact force, the impact force can be mitigated layer by layer to avoid being directly transmitted to other precision components of the drone.

[0083] Through the design of a multi-stage buffer system, the cooperation between the connecting rod 27, the buffer rod, the telescopic block 25 and the track plate 24 allows the impact force of the UAV during landing to be absorbed and dispersed step by step, thereby effectively reducing the impact of the ground on the mounting frame 1 and other equipment, and ensuring the safety and stability of each key component of the UAV.

[0084] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
