Description

Technical Field

[0001] This invention relates to the technical field of drone mounting structures, specifically a mounting mechanism for a fire extinguishing device for drones. Background Technology

[0002] In the field of drone applications, with the increasing demand for scenarios such as fire fighting and agricultural plant protection, it is becoming more and more common for drones to carry functional devices (such as fire extinguishing devices and spraying devices) to perform tasks. Drones can quickly reach the target area due to their flexibility and maneuverability. However, how to efficiently adapt to different functional payloads and simplify the loading process has become the key to improving the efficiency of drone operations in multiple scenarios, and has driven the development of loading mechanisms towards convenience and modularity.

[0003] Currently, drones equipped with fire extinguishing and spraying devices are mainly fixed by multiple sets of bolts. That is, at the pre-set mounting position on the drone body, the brackets of the fire extinguishing and spraying devices are rigidly fastened to the body using bolts, and the load is transferred by the mechanical locking of the bolts. This method relies on mature mechanical connection technology, can meet the basic load fixing requirements, and is widely used in simple mission scenarios. It has achieved the initial integration of drones and functional devices, and provides basic support for expanding the operational boundaries of drones.

[0004] The existing bolt-connected mounting method has significant drawbacks in actual operation. On the one hand, when changing functional devices (such as switching from fire extinguishing to spraying or replacing fire extinguishing water pipes with fire extinguishing bombs), multiple sets of bolts need to be disassembled and installed one by one, which is cumbersome and time-consuming. Especially in emergency fire fighting and other scenarios with high requirements for response speed, this delays the mission. On the other hand, frequent disassembly and assembly of bolts can easily lead to wear at the mounting position and stripping of threads, reducing connection reliability and affecting the coordinated stability of the UAV and functional devices. In addition, multi-bolt connections require high installation precision. In complex environments such as the field and high altitudes, it is difficult to quickly complete the replacement when there is a lack of professional tools, which limits the flexibility and efficiency of UAV operations in multiple scenarios. There is an urgent need to innovate the mounting mechanism to break through the bottlenecks of replacement efficiency and connection reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a mounting mechanism for a fire extinguishing device for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting mechanism for a fire extinguishing device for a drone, comprising a mounting mechanism body consisting of a mounting plate and a docking load-bearing plate, wherein the mounting plate and the docking load-bearing plate are respectively connected to the drone legs and the drone body, and the mounting mechanism body is provided with a support and a limiter for connecting and fixing the mounting plate and the docking load-bearing plate.

[0007] The support includes:

[0008] The side plate is installed on the side wall of the connecting load-bearing plate, and the side plate is fitted with a side support plate that is in contact with the bottom surface of the mounting plate. The mounting plate is provided with a quick-release unlocking groove corresponding to the side plate and the side support plate.

[0009] An end plate is fixedly installed on the bottom of the docking load-bearing plate, and an end groove is provided on the mounting plate to slide and connect with the end plate. A bottom support plate is installed on the end plate to be in contact with the bottom surface of the mounting plate.

[0010] The limiter includes:

[0011] The wheel seat is slidably mounted inside the mounting plate, and the side wall of the wheel seat is provided with a limiting plate;

[0012] A limiting groove is formed on the top of the mounting plate and connected to the limiting plate;

[0013] A spring, mounted on top of the wheel seat, provides the force for the wheel seat to move downwards.

[0014] Preferably, the side wall of the connecting load-bearing plate is provided with a side groove that is in contact with the outer wall of the side connecting plate, and the side connecting plate and the side support plate are connected by multiple sets of bolts, and the multiple sets of bolts pass through the side connecting plate and the side support plate and are connected to the threaded holes opened in the side connecting groove.

[0015] By adopting the above technical solution, the side groove and the side plate are fitted together, and the side support plate is bolted together, which effectively enhances the structural stability of the support and improves the overall connection strength.

[0016] Preferably, two sets of side plates are symmetrically installed on the outer walls of both sides of the docking load-bearing plate. The outer walls of both sets of side plates are in contact with the outer wall of the mounting plate, and the bottom corner of the side plate near the outer wall of the mounting plate is designed at an angle.

[0017] By adopting the above technical solution, the two sets of side plates are installed symmetrically, and the bottom corners of the side plates are designed at an angle, which facilitates insertion into the quick-connect unlocking slot and improves docking efficiency and guidance.

[0018] Preferably, the side support plate is L-shaped, and the top surface of the bottom end of the side support plate is in contact with the bottom surface of the mounting plate, and the length of the end of the side support plate in contact with the mounting plate is greater than the thickness of the mounting plate;

[0019] After the mounting mechanism body is installed, the positions of the side connecting plate and the side support plate are offset from the positions of the quick-connect unlocking slot, and the length and width of the quick-connect unlocking slot are greater than the width and thickness of the side connecting plate and the side support plate.

[0020] By adopting the above technical solution, the displacement of the mounting plate is restricted under the action of the side connecting plate and the side support plate.

[0021] Preferably, the side support plate has a mating groove corresponding to the thickness of the side connecting plate, and the bottom of the side connecting plate has a snap-fit ​​groove corresponding to the thickness of the side support plate, and the side connecting plate and the side support plate are snapped together by the mating groove and the snap-fit ​​groove.

[0022] By adopting the above technical solution, the side support plate and the side connecting plate are engaged through the mating groove and the snap-fit ​​groove, which enhances the connection stability and facilitates disassembly and maintenance.

[0023] Preferably, two sets of end plates are symmetrically installed on the bottom surface of the end of the connecting load-bearing plate, and each end plate is equipped with a bottom support plate. After the bottom support plate is connected to the end plate, the overall cross section is designed in a "+" shape.

[0024] The width of the bottom support plate is greater than the thickness of the mounting plate, and the top corner of the bottom support plate is designed with an angle, and the length of the bottom support plate is greater than the width of the end groove.

[0025] By adopting the above technical solution, the angled design of the bottom support plate makes it easy to slide to the bottom of the mounting plate to support the mounting plate.

[0026] Preferably, the limiter further includes:

[0027] The mounting box is installed on top of the docking support plate and is offset from the drone body. The mounting box is slidably connected to the wheel seat, and the inner wall of the mounting box is connected to the spring.

[0028] The buffer wheel is rotatably mounted on the wheel seat and is in contact with the top surface of the mounting plate;

[0029] Wheel grooves are formed on the top of the mounting plate and correspond to the position of the buffer wheels;

[0030] A connecting bracket is installed on the side wall of the wheel seat and connected to the limiting plate.

[0031] By adopting the above technical solution, the buffer wheel is driven by the spring inside the box, and as it falls into the wheel groove, it drives the limiting plate to insert into the limiting groove, thereby restricting the lateral movement of the mounting plate.

[0032] Preferably, two sets of wheel seats are symmetrically installed in the mounting box, and two sets of docking rods connected to the wheel seats are slidably installed in the mounting box, and the docking rods are slidably connected to a limiting rod that is fixedly connected to the docking load-bearing plate.

[0033] The mounting box contains a U-shaped frame connected to the docking rod. When the U-shaped frame moves, it will drive the two sets of wheel seats to move synchronously through the docking rod.

[0034] By adopting the above technical solution, the two sets of wheel seats are linked with the U-shaped frame through the docking rod, ensuring that the limit on both sides is synchronized, the force is evenly distributed, and the stability is improved.

[0035] Preferably, a drag-reducing wheel is rotatably mounted in the middle of the U-shaped frame, a U-shaped frame is mounted on the outer wall of the mounting box, and a rocker plate that is in contact with the drag-reducing wheel is rotatably mounted inside the U-shaped frame via a torsion spring and a rotating shaft, with the outer end of the rocker plate located outside the mounting box.

[0036] By adopting the above technical solution, the rocker's downward pressure drives the U-shaped frame through the drag-reducing wheel, releasing the locking of the limit plate, achieving quick unlocking and convenient operation.

[0037] Preferably, the distance between the outer end of the rocker and the outer wall of the U-shaped frame is greater than the length of the rocker located at the inner end of the mounting box, and the outer wall of the rocker is fitted with a sealing plate that is in contact with the outer wall of the U-shaped frame.

[0038] By adopting the above technical solution, the design of the rocker's outer end spacing is more labor-saving, while the sealing plate can prevent debris and ensure the long-term reliable operation of the limit switch.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. The fire extinguishing device mounting mechanism for this drone features angled side plates that automatically align when inserted into the quick-connect unlocking slot, preventing installation jamming due to manual alignment errors. The side support plates on the side plates are L-shaped, with their bottom ends fitting snugly against the bottom surface of the docking support plate. The length of the end in contact with the mounting plate is greater than the thickness of the mounting plate. When the side plates slide outside the quick-connect unlocking slot, the bottom surfaces of the side support plates and the mounting plate fit tightly together, forming a bottom support. Simultaneously, end plates are symmetrically installed at the bottom of the docking support plate. The bottom support plate and the end plate are connected in a cross shape. The beveled design of the top corner of the bottom support plate makes it easy to slide into the end groove. After sliding into place, the top surface of the bottom support plate fits against the bottom surface of the mounting plate, and together with the side support plate, it restricts the vertical displacement of the mounting plate. This structure allows for easy installation by simply pushing the docking load-bearing plate to slide, and the fixing can be completed through the linkage of the side plate and the end plate. No bolts or other tools are required. When disassembling, press the rocker to release the limit and slide the docking load-bearing plate in the opposite direction to separate it. The whole process is smooth and convenient, effectively improving the replacement efficiency.

[0041] 2. The fire extinguishing device mounting mechanism for this UAV features wheel seats that slide within the mounting box. A spring at the top of the wheel seat provides downward force to the wheel seat, and a buffer wheel rotates and mounts on the wheel seat, fitting snugly against the top surface of the mounting plate. Once the docking support plate slides into position with the mounting plate, the spring drives the buffer wheel into the wheel groove at the top of the mounting plate. Simultaneously, the wheel seat, through a connecting frame, drives a limiting plate to insert into a limiting groove, thus restricting the lateral displacement of the mounting plate. The outer wall of the side connecting plate fits against the outer wall of the mounting plate, and the end connecting plate engages with the end connecting groove, further restricting the lateral movement of the docking support plate. This multi-dimensional limiting design ensures the mounting plate is securely fixed in both horizontal and vertical directions. Furthermore, the U-shaped frame, through a connecting rod, links the two sets of wheel seats to move synchronously, ensuring even distribution of limiting forces on both sides and preventing tilting of the mounting plate due to unilateral force. This effectively prevents the fire extinguishing device from shaking or falling off during UAV flight, ensuring the stability of the mounting.

[0042] 3. The fire extinguishing device mounting mechanism for this drone features side plates and side support plates that interlock via docking grooves and snap-fit ​​grooves, and are then bolted into the side grooves of the docking load-bearing plate. This modular connection method allows for independent disassembly and replacement of individual components when damaged, eliminating the need to disassemble the entire mounting mechanism and reducing maintenance complexity. The limiter's rocker arm has a sealing plate at its outer end, which fits snugly against the outer wall of the U-shaped frame, preventing rainwater, sand, and other debris from entering the mounting box and protecting precision components such as springs and wheel seats. Simultaneously, the springs provide elastic cushioning for the buffer wheels; when the drone encounters airflow impacts or takeoff / landing turbulence, the buffer wheels can float up and down with the wheel seats, absorbing vibration energy and reducing impact on the mounting device. Furthermore, the sliding fit between the end groove and end plate, and the guiding design of the quick-release unlocking groove and side plate, allow the mechanism to adapt to minor installation errors to a certain extent. Even in less than ideal environments such as the field, operators can easily complete the mounting process, broadening the device's application scenarios.

[0043] 4. The fire extinguishing device mounting mechanism of this drone, through the angled design of the side and end plates and the support structure of the bottom and side support plates, not only achieves rapid docking but also automatically locks after installation through structural limits, reducing manual operation steps. The distance between the outer end of the limiter's rocker arm and the outer wall of the U-shaped frame has been optimized, allowing operators to easily trigger unlocking with a finger press. The rocker arm automatically resets via a torsion spring, making operation effortless and convenient. When replacing the fire extinguishing device, only two main steps are required: pressing the rocker arm and sliding the docking support plate. No additional tools are needed, significantly shortening the replacement time. Especially in time-sensitive scenarios such as emergency rescue, this can help the drone quickly deploy and improve mission efficiency. At the same time, the connection structure of each component adopts mechanical limits, avoiding safety hazards caused by loose bolts and ensuring the safety of the drone during flight and operation.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please see Figures 1 to 10 The present invention provides a technical solution: a fire extinguishing device mounting mechanism for unmanned aerial vehicles, the main body of which is the mounting mechanism body 1, and the mounting mechanism body 1 is composed of a mounting plate 10 and a docking load-bearing plate 11;

[0061] The mounting plate 10 is connected to the drone legs 2, and the docking load-bearing plate 11 is fixed to the drone body 3. The mounting mechanism body 1 is equipped with a support and a limiter 4 to achieve a stable connection between the two.

[0062] Specifically, the support consists of two main components: a side plate 12 and an end plate 13.

[0063] The side plate 12 is installed on the side wall of the connecting load-bearing plate 11. The side support plate 120 installed on it is in close contact with the bottom surface of the mounting plate 10. At the same time, the mounting plate 10 is provided with a quick-connect unlocking groove 121. The quick-connect unlocking groove 121 can accommodate the insertion of the side plate 12 and the side support plate 120. After the two slide into place, they can be limited by being misaligned.

[0064] Secondly, the end plate 13 is fixed to the bottom of the supporting plate 11, and it forms a sliding connection with the mounting plate 10 through the end groove 130. The bottom support plate 131 on the end plate 13 is also in contact with the bottom surface of the mounting plate 10. During the installation process, when the side plate 12 and the end plate 13 slide to the designated position, the side support plate 120 and the bottom support plate 131 will support the mounting plate 10 from the bottom, effectively restricting its up and down movement, thereby completing the initial fixation.

[0065] In some examples, the side support plate 120 has a mating groove 123 corresponding to the thickness of the side connecting plate 12, and the bottom of the side connecting plate 12 has a snap-fit ​​groove 124 corresponding to the thickness of the side support plate 120. The side connecting plate 12 and the side support plate 120 are snapped together by the mating groove 123 and the snap-fit ​​groove 124, making the connection between the side support plate 120 and the side connecting plate 12 more stable. At the same time, the side support plate 120 and the side connecting plate 12 will be subjected to force and restrain each other, further enhancing the use effect of the side support plate 120 and the side connecting plate 12.

[0066] Of course, in other examples, the side support plate 120 and the side connecting plate 12 can be connected to each other by welding.

[0067] In this embodiment, a side groove 122 is provided on the side wall of the load-bearing plate 11. After the side plate 12 and the side support plate 120 are connected by multiple sets of bolts, they will be embedded in the side groove 122 and then connected to the threaded hole in the side groove 122 by bolts. This design can significantly enhance the connection stability between the two.

[0068] It is worth noting that two sets of side plates 12 are symmetrically arranged on both sides of the load-bearing plate 11. Their outer walls are closely fitted with the outer walls of the mounting plate 10. Furthermore, the bottom corner of the side plate 12 near the outer wall of the mounting plate 10 is designed with an angle. This detail allows the side plate 12 to be inserted into the quick-connect unlocking slot 121 more smoothly.

[0069] In this embodiment, the side support plate 120 has an L-shaped structure, with its bottom top surface fitting against the bottom surface of the mounting plate 10. The length of the end of the side support plate 120 that fits against the mounting plate 10 is greater than the thickness of the mounting plate 10, thus ensuring support strength. After the mounting mechanism body 1 is installed, the side connecting plate 12 and the side support plate 120 will slide out of the quick-connect unlocking groove 121 and form a misalignment with the quick-connect unlocking groove 121. At this time, the side support plate 120 restricts its displacement by fitting against the bottom surface of the mounting plate 10. Meanwhile, the length and width of the quick-connect unlocking groove 121 are both greater than the dimensions of the side connecting plate 12 and the side support plate 120, which can avoid interference during sliding.

[0070] For example, two sets of end plates 13 are symmetrically installed on the bottom surface of the end of the connecting load-bearing plate 11. Each set of end plates 13 is provided with a bottom support plate 131. After the two are connected, the overall cross section is "+". The width of the bottom support plate 131 is greater than the thickness of the mounting plate 10, and its top corner is designed with an angle, which helps the bottom support plate 131 to slide smoothly to the bottom of the mounting plate 10.

[0071] In addition, the length of the bottom support plate 131 is greater than the width of the end joint groove 130. When the end joint plate 13 slides into place, the bottom support plate 131 will fit against the bottom surface of the mounting plate 10. During this process, the end joint groove 130 and the end joint plate 13 cooperate with each other to effectively limit the lateral movement of the docking load-bearing plate 11. Combined with the supporting effect of the side support plate 120, a multi-directional stable limit is formed.

[0072] In this embodiment, the limiter 4 is mainly composed of a mounting box 40, a wheel seat 41, and a buffer wheel 42;

[0073] The wheel seat 41 slides within the mounting box 40, and the spring 45 mounted on its top provides downward force to the wheel seat 41. The buffer wheel 42 is rotatably mounted on the wheel seat 41 and fits against the top surface of the mounting plate 10. The wheel groove 420 on the top of the mounting plate 10 corresponds to the position of the buffer wheel 42. When the docking load-bearing plate 11 is connected to the mounting plate 10, the buffer wheel 42 falls into the wheel groove 420. At this time, the wheel seat 41 drives the limiting plate 44 to insert into the limiting groove 440 through the connecting frame 43, thereby restricting the lateral movement of the mounting plate 10.

[0074] To achieve synchronous operation, two sets of wheel seats 41 are symmetrically arranged inside the mounting box 40. They are connected to the U-shaped frame 47 through the docking rod 46. When it is necessary to release the limit, simply press down on the rocker plate 490. When the rocker plate 490 rotates, its inner end will push the drag-reducing wheel 48 upward. The drag-reducing wheel 48 will then drive the U-shaped frame 47 to move upward, thereby causing the limit plate 44 to disengage from the limit groove 440.

[0075] At the same time, multiple sets of limiting rods 460 that are slidably connected to the connecting rods 46 are also installed on the connecting load-bearing plate 11 (such as...). Figure 10 As shown, when the docking rod 46 slides, the limiting rod 460 will support and limit the docking rod 46 to ensure that it can move up and down smoothly and stably.

[0076] It is worth mentioning that the distance between the outer end of the rocker 490 and the outer wall of the U-shaped frame 49 is greater than the length of the rocker 490 located at the inner end of the mounting box 40, which can ensure that the operation is more effortless. The sealing plate 491 on the outer wall of the rocker 490 can prevent foreign objects from entering, and the torsion spring can make the rocker 490 automatically reset after the operation is completed.

[0077] During installation, once the side plate 12 and end plate 13 have slid into place, the support will provide support for the mounting plate 10 from the bottom. At the same time, the limiter 4 locks the lateral position of the mounting plate 10 through the buffer wheel 42 and the limit plate 44. This multi-dimensional fixing method can effectively prevent the mounting plate 10 from shaking and ensure the stability of the device mounted on the UAV during flight.

[0078] When replacing the mounting device, the operator only needs to press the rocker arm 490 to release the limit, and then pull the docking load-bearing plate 11 so that the side support plate 120 and the bottom support plate 131 slide out of the quick-connect unlocking groove 121 and the end connection groove 130 respectively, which can quickly complete the disassembly. For the new mounting plate 10, the installation can be completed by sliding and docking in the opposite direction. The whole process does not require bolt removal and installation, which greatly improves the efficiency of replacement and is especially suitable for emergency rescue and other scenarios with tight time.

[0079] The working principle of this invention is as follows: When docking with this mechanism is required, firstly, the mounting plate 10 of the mounting mechanism body 1 is connected to the drone legs 2, and the docking load-bearing plate 11 is connected to the drone body 3. (It should be noted that under normal circumstances, the equipment to be mounted, such as fire-fighting equipment, pesticide spraying equipment, etc., is directly installed on the corresponding mounting plate 10. The specific installation method is also a well-known technology, so it will not be described in detail. At the same time, the drone legs 2 and the corresponding mounting plate 10, and the drone body 3 and the corresponding docking load-bearing plate 11 are continuously connected. When replacing them later, the mounting plate 10 and the docking load-bearing plate 11 can be separated directly, and then the mounting plate 10 can be replaced.)

[0080] Next, place the drone legs 2 stably on the ground or work platform to ensure the stability of the subsequent docking operation; then, insert the side plate 12 and the side support plate 120 into the quick-connect unlocking slot 121 until the bottom surface of the docking load-bearing plate 11 is in contact with the top surface of the mounting plate 10. At this time, the docking load-bearing plate 11 and the mounting plate 10 are initially connected.

[0081] As the distance between the docking load-bearing plate 11 and the mounting plate 10 gradually decreases, the buffer wheel 42 will come into contact with the mounting plate 10. As the distance between the docking load-bearing plate 11 and the mounting plate 10 gradually decreases, the buffer wheel 42 will be blocked by the mounting plate 10 and will not be able to continue to descend. As a result, the buffer wheel 42 will begin to move upward relative to the side plate 12, so that the spring 45 will be compressed by the wheel seat 41 and begin to be in a state of compressed energy storage.

[0082] Once the docking load-bearing plate 11 is in contact with the mounting plate 10, the docking load-bearing plate 11 can be pushed, causing it to slide the side support plate 120 out of the quick-release unlocking slot 121 via the side connecting plate 12. At this point, the side support plate 120 will be in contact with the bottom surface of the mounting plate 10, initially defining the position between the docking load-bearing plate 11 and the mounting plate 10. As the side support plate 120 is in contact with the bottom surface of the mounting plate 10, the outer wall of the side connecting plate 12 will also be in contact with the outer wall of the mounting plate 10, further restricting the position of the mounting plate 10 and the docking load-bearing plate 11. Simultaneously, the sliding of the docking load-bearing plate 11 will also cause the end plate 13 to slide synchronously, so that the end plate 13 enters the end groove 130. The end groove 130 will cooperate with the end plate 13 to restrict the sliding trajectory of the docking load-bearing plate 11. As the docking load-bearing plate 11 continues to slide, the bottom support plate 131 will slide to the bottom of the mounting plate 10 and stick to the bottom surface of the mounting plate 10, thereby further limiting the connection between the docking load-bearing plate 11 and the mounting plate 10, and further ensuring that the mounting plate 10 can stably drive the device it is mounted during subsequent use.

[0083] When the docking support plate 11 slides until the end plate 13 abuts against the inner wall of the end groove 130, the docking support plate 11 has slid to a limited position and can no longer slide. At this time, the buffer wheel 42 has also moved above the wheel groove 420. At this time, the wheel seat 41, under the action of the spring 45, pushes the buffer wheel 42 into the wheel groove 420, causing the wheel seat 41 and the buffer wheel 42 to descend. As the wheel seat 41 descends, it will drive the limiting plate 44 to descend synchronously through the connecting frame 43, so that the limiting plate 44 enters the limiting groove 440 and abuts against the inner wall of the limiting groove 440. One end of the mounting plate 10 is restricted from sliding by the end plate 13, and the other end is restricted from sliding by the limiting plate 44 and the limiting groove 440, which effectively prevents serious movement of the mounting plate 10. During subsequent work, multiple sets of side support plates 120 and multiple sets of bottom support plates 131 will support the bottom of the mounting plate 10, while multiple sets of side support plates 12, multiple sets of end plate 13 and multiple sets of limiting plates 44 and limiting groove 440 will cooperate to restrict the four sides of the mounting plate 10, further ensuring the stability of the mounting plate 10 when the UAV body 3 drives the docking load-bearing plate 11 and the mounting plate 10 to move.

[0084] When different mounting devices need to be replaced, pressing down on the rocker arm 490 causes it to rotate. At this time, the torsion spring is under stress. As the rocker arm 490 rotates, its inner end pushes the drag-reducing wheel 48 upwards, causing the drag-reducing wheel 48 to drive the U-shaped frame 47 upwards. Because the U-shaped frame 47 is connected to multiple sets of wheel seats 41 via multiple sets of connecting rods 46, the multiple sets of wheel seats 41 will move upwards as the rocker arm 490 is pressed, causing the limiting plate 44 to leave the limiting groove 440. At this time, the limitation of the limiting plate 44 and the limiting groove 440 on the mounting plate 10 is released, and the user can pull the connecting load-bearing plate 11, causing it to begin sliding in the opposite direction of installation. Once the connecting load-bearing plate 11 begins to slide... When the buffer wheel 42 moves, the position of the buffer wheel 42 and the wheel groove 420 will be misaligned. At this time, the rocker 490 can be released, causing the torsion spring to be released from its restriction. The rocker 490 will automatically reset under the action of the torsion spring, which is convenient for subsequent use. However, the buffer wheel 42 is now misaligned with the wheel groove 420, which makes it restricted by the mounting plate 10 and unable to slide into the wheel groove 420. At this time, the user only needs to continue to push the docking load plate 11 until the docking load plate 11 slides to the state where the side support plate 120 and the quick-connect unlocking groove 121 are misaligned. Then the docking load plate 11 can be removed from the mounting plate 10. Then the docking load plate 11 can be installed on another set of mounting plates 10 with the mounting device that needs to be replaced in the above installation method.

[0085] During the resetting process of rocker plate 490, sealing plate 491 will come into contact with the outer wall of U-shaped frame 49, thereby covering the opening of U-shaped frame 49 and preventing a large amount of external debris from entering U-shaped frame 49 and mounting box 40 and affecting the internal components of mounting box 40.

[0086] The mounting mechanism, through the mechanical linkage between the support and the limiter 4, allows for easy replacement of mounting devices. Simply press the rocker arm 490 and push the docking support plate 11, then place the docking support plate 11 onto another set of mounting plates 10 and push the docking support plate 11 again to complete the replacement. This enables the rapid installation of mounting devices such as fire extinguishing devices and spraying devices onto the UAV body 3, effectively solving the problems of low efficiency and poor reliability of traditional bolt connections in emergency scenarios. It significantly improves the response speed and multi-task adaptability of UAVs in multi-scenario operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
