Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a buffer-stabilized UAV main control system. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. They involve sensor technology, communication technology, information processing technology, intelligent control technology, and aerospace propulsion technology, and are a high-tech product of the information age. The development and popularization of UAV technology have enabled them to demonstrate unique advantages in many fields, with their main applications being aerial photography, agricultural plant protection, geological exploration and surveying, and disaster relief.

[0003] Currently, the main control system of drones is integrated and fixed inside the fuselage. When the drone ascends or descends rapidly, the main control system is prone to loosening under the impact. After long-term use, it is easy to experience power outages due to poor contact, resulting in poor stability of the main control system. Secondly, drones are inevitably subject to collisions due to improper operation during flight. Drone batteries that have been impacted are prone to spontaneous combustion, posing certain safety hazards. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a buffer-stabilized main control system for a drone. This main control system can effectively reduce the impact when the drone is rising or falling rapidly by deploying buffer airbags around the main control unit, thereby making it more stable. Secondly, by deploying fire-extinguishing airbags around the main control unit, it can effectively and quickly extinguish the flame when the drone is hit and the battery spontaneously combusts, thereby further reducing safety hazards.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A buffer-stabilized unmanned aerial vehicle (UAV) main control system includes a main control unit, a flight unit, and a camera unit, wherein the flight unit and the camera unit are respectively installed on the top and bottom of the main control unit by screws; the main control unit includes a main housing, and a main control unit is installed inside the main housing;

[0007] A side buffer air cushion is installed on the side of the main control unit, which completely fills the side gap between the main housing and the main control unit; a bottom buffer air cushion and a top buffer air cushion are installed on the bottom and top surfaces of the main control unit, respectively, which completely fill the bottom gap and top gap between the main housing and the main control unit.

[0008] The side cushioning air cushion, bottom cushioning air cushion and top cushioning air cushion are equipped with evenly distributed cushioning airbags; between each pair of adjacent cushioning airbags, there is also a fire extinguishing airbag, which is filled with flame retardant powder, such as aluminum hydroxide powder.

[0009] The main control unit includes a main controller, and an attitude detection module, a power supply module, a communication module, and a motor drive module that are electrically connected to the main controller in sequence. The attitude detection module includes an accelerometer, an angular velocity sensor, and a geomagnetic sensor. The attitude detection module is used to detect the acceleration, angular velocity, and magnetic field strength of the UAV in three directions and send them to the main controller. The main controller obtains the current attitude of the UAV based on the data sent by the attitude detection module.

[0010] By adopting the above scheme, the main control system can effectively reduce the impact when the drone is rising or falling rapidly by deploying buffer airbags around the main control unit, thus making it more stable; secondly, by deploying fire extinguishing airbags around the main control unit, it can effectively and quickly extinguish the flame when the drone is hit and the battery spontaneously combusts, thus further reducing safety hazards.

[0011] In a preferred embodiment of the main control system for a buffer-stabilized UAV, the buffer airbag is filled only with inert gas at a pressure of 1.2-1.5 bar, wherein the inert gas is nitrogen or the like; the volume of the buffer airbag after being filled and expanded is larger than the volume of the fire extinguishing airbag after being filled and expanded, so that only the buffer airbag comes into contact with the main control unit.

[0012] In order to improve the stability of the gas inside the airbag, the above solution uses inert gas such as nitrogen to fill the airbag and increases its pressure. At this time, the airbag is in contact with the main control unit, which can effectively reduce the impact on the main control unit.

[0013] In a preferred embodiment of the main control system for a buffer-stabilized UAV, the fire extinguishing airbag is also filled with an inert gas at a pressure of 1.5-2.0 bar, wherein the inert gas is nitrogen or the like.

[0014] In order to further improve the extinguishing effect of the fire extinguishing airbag, the above scheme is adopted, and inert gases such as nitrogen are filled into it. Once the battery spontaneously combusts, it can quickly burn through the fire extinguishing airbag. At the moment of rupture, the fire extinguishing airbag will rapidly diffuse the flame retardant powder under the action of high pressure inert gas, thereby quickly achieving flame retardancy.

[0015] In a preferred embodiment of the main control system of a buffer-stabilized UAV, a lower positioning frame and an upper positioning frame are installed in the side gap between the main shell and the main control unit. The lower positioning frame and the upper positioning frame are inserted and installed vertically, and the side buffer air cushion, the bottom buffer air cushion and the top buffer air cushion can be limited and fixed through the lower positioning frame and the upper positioning frame.

[0016] Both the lower positioning frame and the upper positioning frame have horizontally set horizontal limiting posts fixed at the four corners of their respective inner sides. These horizontal limiting posts can press and limit the four corners of the bottom surface buffer air pad or the top surface buffer air pad.

[0017] Each limiting post of the lower positioning frame is also fixed with a vertically arranged vertical limiting post one, and a slot is opened at the end of the vertical limiting post one; each limiting post of the upper positioning frame is also fixed with a vertically arranged vertical limiting post two, and a plug is fixed at the end of the vertical limiting post two; wherein, the plug and the slot are interference fit.

[0018] To further enhance the limiting effect of each buffer gas using the above scheme, the bottom buffer gas pad is first placed inside the main housing during limiting. Then, the lower positioning frame is placed inside the main housing and fixed with screws. The bottom buffer gas pad is pressed and fixed by the horizontal limiting post. Next, the side buffer gas pads are placed on the lower positioning frame, and the four corners of the side buffer gas pads are limited by the vertical limiting post. Then, the main control unit is placed inside the side buffer gas pads. The top buffer gas pad is then placed on top of the main control unit. Finally, the upper positioning frame is inserted into the lower positioning frame and fixed with screws. The top buffer gas pad is pressed and fixed by the horizontal limiting post.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] 1. The main control system effectively reduces the impact when the drone is rising or falling rapidly by deploying buffer airbags around the main control unit, thus making it more stable; secondly, by deploying fire extinguishing airbags around the main control unit, it can effectively and quickly extinguish the flame when the drone is hit and the battery spontaneously combusts, thus further reducing safety hazards.

[0021] 2. In order to improve the stability of the gas inside the airbag, inert gases such as nitrogen are used for filling and the gas pressure is increased. At this time, the airbag is in contact with the main control unit, which can effectively reduce the impact on the main control unit.

[0022] 3. In order to further enhance the extinguishing effect of the fire extinguishing airbag, inert gases such as nitrogen are filled into it. Once the battery spontaneously combusts, it can quickly burn through the fire extinguishing airbag. At the moment of rupture, the fire extinguishing airbag will rapidly diffuse the flame retardant powder under the action of high-pressure inert gas, thereby quickly achieving flame retardancy.

[0023] 4. To further enhance the limiting effect of each buffer gas, the bottom buffer gas pad is first placed inside the main housing during limiting. Then, the lower positioning frame is placed inside the main housing and fixed with screws. The bottom buffer gas pad is pressed and fixed by the horizontal limiting post. Next, the side buffer gas pads are placed on the lower positioning frame, and the four corners of the side buffer gas pads are limited by the vertical limiting post. Then, the main control unit is placed inside the side buffer gas pads. The top buffer gas pad is placed on top of the main control unit. Finally, the upper positioning frame is inserted into the lower positioning frame and fixed with screws. The top buffer gas pad is pressed and fixed by the horizontal limiting post.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 10As shown, a main control system for a buffer-stabilized unmanned aerial vehicle (UAV) includes a main control unit 1, a flight unit 2, and a camera unit 3. The flight unit 2 and the camera unit 3 are respectively installed and removed from the top and bottom of the main control unit 1 by screws. The main control unit 1 includes a main housing 4, and a main control unit 5 is installed inside the main housing 4. Side buffer air cushions 6 are installed on the sides of the main control unit 5, which completely fill the side gap between the main housing 4 and the main control unit 5. Bottom buffer air cushions 7 and top buffer air cushions 8 are installed on the bottom and top surfaces of the main control unit 5, respectively, which completely fill the bottom gap and top gap between the main housing 4 and the main control unit 5, respectively. The buffer air cushion 6, bottom buffer air cushion 7, and top buffer air cushion 8 are equipped with evenly distributed buffer airbags 9; between each pair of adjacent buffer airbags 9, there is also a fire extinguishing airbag 10, which is filled with flame retardant powder 11, such as aluminum hydroxide powder; the main control unit 5 includes a main controller, and an attitude detection module, a power supply module, a communication module, and a motor drive module that are electrically connected to the main controller in sequence; the attitude detection module includes an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor. The attitude detection module is used to detect the acceleration, angular velocity, and magnetic field strength of the UAV in three directions and send them to the main controller. The main controller obtains the current attitude of the UAV based on the data sent by the attitude detection module. This main control system effectively reduces the impact when the UAV is rising or falling rapidly by deploying buffer airbags 9 around the main control unit 5, thus making it more stable; secondly, by deploying fire extinguishing airbags 10 around the main control unit 5, it can effectively and quickly extinguish the flame when the UAV's battery spontaneously combusts due to an impact, further reducing safety hazards.

[0038] The buffer airbag 9 is filled only with inert gas at a pressure of 1.2-1.5 bar, including nitrogen and other inert gases. The expanded volume of the buffer airbag 9 is greater than that of the expanded volume of the fire extinguishing airbag 10, ensuring that only the buffer airbag 9 contacts the main control unit 5. To improve the stability of the gas inside the buffer airbag 9, inert gases such as nitrogen are used, and its pressure is increased. At this point, the buffer airbag 9 contacts the main control unit 5, effectively mitigating the impact on the main control unit 5.

[0039] The fire extinguishing airbag 10 is also filled with inert gas at a pressure of 1.5-2.0 bar, including nitrogen and other inert gases. To further enhance the extinguishing effect of the fire extinguishing airbag 10, it is further filled with inert gases such as nitrogen. In the event of spontaneous combustion of the battery, the fire extinguishing airbag 10 can be quickly burned through. At the moment of rupture, the flame retardant powder 11 is rapidly diffused under the action of the high-pressure inert gas, thereby quickly achieving flame retardancy.

[0040] like Figure 4 , Figures 7 to 10 As shown, a lower positioning frame 12 and an upper positioning frame 13 are installed at the side gap between the main housing 4 and the main control unit 5. The lower positioning frame 12 and the upper positioning frame 13 are inserted and installed vertically, and the side buffer air cushion 6, the bottom buffer air cushion 7 and the top buffer air cushion 8 can be limited and fixed by the lower positioning frame 12 and the upper positioning frame 13. Both the lower positioning frame 12 and the upper positioning frame 13 have horizontally set horizontal limiting posts 14 fixed at the four corners of their respective inner sides. The horizontal limiting post 14 can press and limit the four corners of the bottom buffer air pad 7 or the top buffer air pad 8; each limiting post of the lower positioning frame 12 is also fixed with a vertically arranged vertical limiting post 15, and the end of the vertical limiting post 15 is provided with a slot 16; each limiting post of the upper positioning frame 13 is also fixed with a vertically arranged vertical limiting post 27, and the end of the vertical limiting post 217 is fixed with a plug 18; wherein, the plug 18 and the slot 16 are interference fit. To further enhance the limiting effect of each buffer gas, the bottom buffer gas pad 7 is first placed inside the main housing 4 during the limiting process. Then, the lower positioning frame 12 is placed inside the main housing 4 and fixed with screws. The bottom buffer gas pad 7 is pressed and fixed by the horizontal limiting post 14. Next, the side buffer gas pad 6 is placed on the lower positioning frame 12, and the four corners of the side buffer gas pad 6 are limited by the vertical limiting post 15. Then, the main control unit 5 is placed inside the side buffer gas pad 6. Then, the top buffer gas pad 8 is placed on top of the main control unit 5. Finally, the upper positioning frame 13 is inserted into the lower positioning frame 12 and fixed with screws. The top buffer gas pad 8 is pressed and fixed by the horizontal limiting post 14.

[0041] The working principle of this utility model:

[0042] Before application, first place the bottom buffer air cushion 7 inside the main housing 4, then place the lower positioning frame 12 inside the main housing 4 and fix the lower positioning frame 12 with screws. Press the bottom buffer air cushion 7 with the horizontal limiting post 14 and fix it. Then place the side buffer air cushion 6 on the lower positioning frame 12 and limit the four corners of the side buffer air cushion 6 with the vertical limiting post 15. Then place the main control unit 5 inside the side buffer air cushion 6, then place the top buffer air cushion 8 on top of the main control unit 5. Finally, insert the upper positioning frame 13 into the lower positioning frame 12 and fix the upper positioning frame 13 with screws. Press the top buffer air cushion 8 with the horizontal limiting post 14 and fix it.

[0043] In application, the main control system deploys buffer airbags 9 around the main control unit 5, which can effectively reduce the impact when the drone is rising or falling rapidly, thus making it more stable. Secondly, by deploying fire extinguishing airbags 10 around the main control unit 5, it can effectively and quickly extinguish the flame when the drone is hit and the battery spontaneously combusts, which can further reduce safety hazards.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
