Description

Technical Field

[0001] It involves the field of drone technology. Background Technology

[0002] With the development of modern society, people are paying increasing attention to the quality and safety of agricultural products. Against this backdrop, agricultural plant protection drones have gradually become an indispensable tool in modern agriculture. Firstly, compared to traditional manual spraying, agricultural plant protection drones can ensure precise positioning and coverage, improving operational efficiency. Secondly, agricultural plant protection drones can reduce the impact on the environment and ecology, protecting the sustainable development of the ecological environment. Traditional agricultural production, with its large-scale use of chemical fertilizers and pesticides, causes significant pollution and resource waste. Agricultural plant protection drones, however, can precisely spray pesticides and fertilizers according to actual needs, avoiding overuse and reducing the impact on the ecological environment. Furthermore, agricultural plant protection drones can promote the sustainability of agricultural production and accelerate the modernization of agriculture. With urbanization and industrialization, rural populations are generally declining, and agricultural production is gradually shrinking. However, the application of agricultural plant protection drones can expand farmers' production space, increase yields and efficiency, while also reducing labor costs and the input of pesticides and fertilizers, making agricultural production more convenient, economical, and efficient.

[0003] In the current development of drones, agricultural plant protection drones can spray liquid pesticides or nutrient solutions such as insecticides, fungicides, herbicides, ripening and defoliating agents, sugar-enhancing agents, and foliar fertilizers. They can also sow solid seeds and perform field surveying. The application of agricultural plant protection drones plays a vital role in controlling pests and diseases and increasing crop yields. However, when traditional agricultural plant protection drones and other spraying equipment spray pesticides on fruit trees and cash crops, the branches of fruit trees grow obliquely upwards, and the outer leaves can obstruct the spray from the inner branches and leaves. When agricultural plant protection drones spray from top to bottom, the pesticides are difficult to penetrate the foliage and achieve uniform spraying across the entire tree. Therefore, traditional agricultural plant protection drones suffer from uneven and incomplete spraying problems.

[0004] In the patent application No. 202021255569.X published on March 23, 2021, an adjustable boom angle drone is provided. Through the angle adjustment mechanism, the angle of the drone boom can be adjusted so that the pesticide sprayed by the drone has a certain angle with the vertical direction. Furthermore, due to the downforce of the rotor, the pesticide sprayed at this angle is further provided with the ability to move and improve the penetration.

[0005] However, according to the publicly available text and accompanying drawings, the angle adjustment is achieved through a detachable angle adjustment component. When a horizontal outrigger is required, the component is connected to the adjustment mechanism, and the outrigger is connected to the component, thus extending the length of the adjustment mechanism and fixing the horizontal posture of the outrigger. When the angle of the outrigger needs to be adjusted, the component is removed, and the outrigger is directly connected to the adjustment mechanism. Because the length of the adjustment mechanism is reduced, the angle of the outrigger is naturally raised.

[0006] Then, the implementation of this structure led to more cumbersome operating procedures when changing the angle. Since the arm angle only needs to be adjusted in specific months of the year, it is necessary to ensure that the disassembled angle adjustment components are well preserved and not lost, which also increases the workload of users and makes the adjustment structure inconvenient to use. Summary of the Invention

[0007] To address the technical problem that existing drone boom angle adjustment mechanisms require more cumbersome operating procedures when changing angles, and that ensuring the intact preservation of disassembled angle adjustment components increases the user's workload, the present invention provides the following technical solution:

[0008] The unmanned aerial vehicle (UAV) arm angle adjustment assembly includes:

[0009] Mounting bracket for connecting the fixed end of the drone arm,

[0010] and a movable seat for connecting the movable end of the robotic arm,

[0011] The movable seat is movably connected to the fixed seat;

[0012] The movable seat is movably provided with an adjustment plate, which adjusts the angle of the movable seat relative to the fixed seat by changing the contact area between itself and the fixed seat.

[0013] Furthermore, a preferred implementation method is provided.

[0014] The movable seat is connected to the fixed seat via a main shaft.

[0015] Furthermore, a preferred implementation method is provided.

[0016] The adjusting plate is connected to the movable seat via an adjusting shaft, which is located on the side of the movable seat away from the main shaft.

[0017] Furthermore, a preferred implementation method is provided.

[0018] The adjusting plate is provided with an adjusting protrusion, and the surface of the fixing groove is provided with at least two fixing grooves, the at least two fixing grooves being at different distances from the adjusting shaft.

[0019] The adjusting protrusions are respectively embedded in the fixed grooves at different distances to adjust the angle of the movable seat relative to the fixed seat.

[0020] Furthermore, a preferred implementation method is provided.

[0021] There are two adjusting protrusions and three fixing grooves;

[0022] The spacing between the fixed grooves is the same as the spacing between the adjusting protrusions.

[0023] Furthermore, a preferred implementation method is provided.

[0024] The adjusting plate has a through hole adjacent to each of the adjusting protrusions; the fixing base has a through hole adjacent to each of the fixing grooves.

[0025] Furthermore, a preferred implementation method is provided.

[0026] The adjusting baffle is provided with an oblique reinforcing structure on the side away from the fixed base. One end of the oblique reinforcing structure is connected to the outer wall of the adjusting shaft, and the other end is connected to the adjusting baffle.

[0027] Furthermore, a preferred implementation method is provided.

[0028] The outer diameter of the movable seat is below the inner diameter of the fixed seat. When adjusting the relative angle between the movable seat and the fixed seat, the side of the movable seat closest to the fixed seat that is away from the spindle can be inserted into the fixed seat.

[0029] Based on the same inventive concept, the present invention also provides a drone arm, the arm including the aforementioned drone arm angle adjustment component.

[0030] Based on the same inventive concept, the present invention also provides a drone, which includes the aforementioned drone arm.

[0031] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows:

[0032] The UAV arm angle adjustment mechanism provided by this invention achieves arm angle adjustment without structural adjustments to the arm base or locking block by using a combination of a movable seat and a fixed seat. The arm angle can be adjusted by directly adjusting the volume of the movable seat to accommodate the fixed seat. Compared with existing adjustment methods, this improves the convenience of angle adjustment and avoids the defect of not being able to return the adjusted arm to its original position due to the loss of components, as no additional components need to be removed.

[0033] The drone arm angle adjustment mechanism provided by this invention achieves precise and stable angle adjustment by adjusting the baffle plate.

[0034] The UAV arm angle adjustment mechanism provided by the present invention further increases the stability of the adjustment mechanism by using a fixing bolt.

[0035] It is suitable for application in research on the adjustment of the arm angle of unmanned aerial vehicles (UAVs). Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0047] Implementation method one, combined with Figure 1-6 This embodiment describes a drone arm angle adjustment component, which includes:

[0048] Mounting bracket 1 for connecting the fixed end of the drone arm.

[0049] and the movable seat 2 for connecting the movable end of the robotic arm,

[0050] The movable seat 2 is movably connected to the fixed seat 1;

[0051] An adjustment plate 22 is movably provided on the movable seat 2. The adjustment plate 22 adjusts the angle of the movable seat 2 relative to the fixed seat 1 by changing the contact area between itself and the fixed seat 1.

[0052] Implementation Method Two: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method One.

[0053] The movable seat 2 is connected to the fixed seat 1 via the main shaft 11.

[0054] Implementation Method 3: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method 2.

[0055] The adjusting baffle 22 is connected to the movable seat 2 via the adjusting shaft 21, which is located on the side of the movable seat 2 away from the main shaft 11.

[0056] Implementation Method Four: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method One.

[0057] The adjusting plate 22 is provided with an adjusting protrusion 23, and the surface of the fixing groove 12 is provided with at least two fixing grooves 12, the at least two fixing grooves 12 being at different distances from the adjusting shaft 21.

[0058] The adjusting protrusions 23 are respectively embedded in the fixed grooves 12 at different distances to adjust the angle of the movable seat 2 relative to the fixed seat 1.

[0059] Implementation Method 5: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method 4.

[0060] There are two adjusting protrusions 23 and three fixing grooves 12;

[0061] The spacing between the fixed grooves 12 is the same as the spacing between the adjusting protrusions 23.

[0062] Furthermore, the structure of the adjusting protrusion 23 and the fixing groove 12 can be adjusted according to actual conditions in this embodiment:

[0063] Specifically, the adjusting protrusion 23 is: two adjusting protrusions 23 with equal distances form a group, and there are two groups in total;

[0064] Specifically, the fixing groove 12 is defined as follows: two fixing grooves 12 that are equidistant from each other form a group, and there are three groups in total;

[0065] The spacing between the three sets of fixed grooves 12 is the same as the spacing between the two sets of adjusting protrusions 23.

[0066] The three sets of fixed grooves 12, together with the two sets of adjusting protrusions 23, provide two adjustable positions for the angle adjustment mechanism. The number of positions can be increased according to actual usage needs. If increased stability is required, it is only necessary to ensure that the number of fixed grooves 12 is one more than the number of adjusting protrusions 23, and that the spacing between the fixed grooves 12 is the same as the spacing between the adjusting protrusions 23.

[0067] Implementation Method Six: This implementation method further defines the UAV arm angle adjustment component provided in either Implementation Method Four or Five.

[0068] The adjusting plate 22 has a through hole adjacent to each adjusting protrusion 23; the fixed base 1 has a through hole adjacent to each fixed groove 12, for fixing the relative position between the movable base 2 and the fixed base 1 by passing the fixing pin 3 through the corresponding two through holes in sequence.

[0069] The fixing pin 3 can be a bolt or other cylindrical structure for fixing. After the arm angle is set and the adjusting protrusion 23 is embedded in the fixing groove 12, the angle adjustment component is further fixed by inserting the fixing pin 3 into the through holes next to the corresponding adjusting protrusion 23 and the fixing groove 12.

[0070] Implementation Method Seven: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method One.

[0071] The adjusting baffle 22 is provided with an oblique reinforcing structure on the side away from the fixed base 1. One end of the oblique reinforcing structure is connected to the outer wall of the adjusting shaft 21, and the other end is connected to the adjusting baffle 22.

[0072] In the side view, the oblique reinforcing structure, the baffle, and the adjusting shaft 21 form a stable triangular structure, which further enhances the stability of the adjusting baffle 22.

[0073] Implementation Method Eight: This implementation method further defines the UAV arm angle adjustment component provided in Implementation Method One.

[0074] The outer diameter of the movable seat 2 is below the inner diameter of the fixed seat 1. When adjusting the relative angle between the movable seat 2 and the fixed seat 1, the side of the movable seat 2 closest to the fixed seat 1 and furthest from the main shaft 11 can be inserted into the fixed seat 1.

[0075] Specifically, on the movable seat 2, the end closer to the fixed seat 1 and the side away from the main shaft 11 is designated as area a 24. On the fixed seat 1, the position closer to area a 24 is designated as area b 13. When the axes of the movable seat 2 and the fixed seat 1 coincide / are parallel (arm extended state), a cavity is formed between area a 24, area b 13 and the lower edge of the adjusting plate 22.

[0076] When the adjusting plate 22 moves toward the fixed seat 1, causing the angle between the movable seat 2 and the fixed seat 1 to change (the drone arm lifts up), the size of the cavity is compressed, and area a 24 extends into the interior of area b 13.

[0077] This design allows the angle adjustment component to be adjusted without altering its own structure, disassembling, or adding new components. The angle can be changed using only its own structure, making it more convenient and faster, and preventing the loss of disassembled parts. The locking block and arm base work together to achieve angle adjustment without structural adjustments to the arm base or locking block. Simply adjusting the volume of the locking block within the arm base is sufficient to adjust the arm's angle. Compared to existing adjustment methods, this improves the convenience of angle adjustment and eliminates the need to disassemble additional components, preventing the inability to return the adjusted arm to its original position due to component loss.

[0078] Implementation Method Nine: This implementation method provides a drone arm, which includes the drone arm angle adjustment component provided in Implementation Method One.

[0079] Implementation Method 10: This implementation method provides a drone, which includes the drone arm provided in Implementation Method 9.

[0080] The above description of several specific embodiments further details the technical solution provided by the present invention in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the above-described specific embodiments are not intended to limit the present invention. Any modifications and improvements to the present invention, reasonable combinations and equivalent substitutions of embodiments based on the spirit and principles of the present invention should be included within the protection scope of the present invention.
