Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically a UAV structure equipped with a navigation system. Background Technology

[0002] With the rapid development of technology, drones have been widely used in various fields, such as aerial photography, logistics delivery, agricultural plant protection, geographic surveying, and power line inspection. As one of the key components of a drone, the navigation system plays a crucial role in the drone's flight path planning, positioning, and precise control.

[0003] In aerial photography, drones rely on navigation systems to accurately pinpoint their shooting locations in order to obtain high-quality, tailored video footage. For example, in aerial photography of large events, drones must fly along predetermined routes to capture images of the event from different angles. The accuracy of the navigation system directly affects the completeness and stability of the footage. If the navigation system deviates due to factors such as vibration during flight, the captured footage may be shaky, discontinuous, or even fail to accurately capture key scenes.

[0004] In logistics and delivery, drones rely on navigation systems to precisely plan delivery routes, ensuring goods are delivered accurately to their destinations. When drones fly in complex urban environments, they must avoid obstacles such as tall buildings, requiring the navigation system to guide their flight accurately in real time. However, existing drones experience vibrations during flight due to factors such as motor operation and airflow. These vibrations, transmitted to the navigation system, can damage its internal precision components, affecting navigation accuracy and stability, and consequently impacting the accuracy and efficiency of logistics and delivery.

[0005] In the field of agricultural plant protection, drones rely on navigation systems to spray pesticides or apply fertilizers to farmland along pre-set routes. If the navigation system deviates due to vibration, it may result in uneven pesticide spraying, with some areas being over-sprayed while others are under-sprayed. This not only affects crop growth but may also cause environmental pollution and resource waste.

[0006] In geographic surveying, drones use navigation systems to determine their flight paths and map terrain features. High-precision surveying requires navigation systems to operate stably and accurately. However, vibration interference can cause positioning errors in navigation systems, leading to inaccurate survey data and affecting subsequent geographic information analysis and applications.

[0007] During power line inspections, drones use navigation systems to fly along power lines and monitor their operational status. If the navigation system deviates from the planned route due to vibrations, it may not be able to comprehensively and accurately inspect all parts of the power lines, thus overlooking potential safety hazards.

[0008] Currently, most drones use relatively simple mounting methods for their navigation systems, such as directly fixing the navigator to the drone body, lacking effective cushioning and protection measures. When the drone encounters turbulence or vibration during flight, the navigator is easily impacted, leading to loosening or damage of internal components, thus reducing the navigator's lifespan and navigation accuracy. Furthermore, existing cushioning structures may be overly complex, increasing the drone's weight and cost, or their cushioning effect may be inadequate, failing to meet the protection requirements of the navigator under various complex flight conditions. Therefore, developing a mounting structure that can effectively cushion and protect the navigator without significantly increasing the drone's weight and cost is of significant practical importance. Summary of the Invention

[0009] This invention provides a drone structure equipped with a navigation system, which solves the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: A drone structure equipped with a navigation system includes a drone body. A navigation mounting assembly is provided on the drone body.

[0011] The navigation mounting assembly includes a navigation unit mounted on the top of the drone body, with a buffer mounting mechanism connecting the navigation unit to the drone body. Positioning the navigation unit on the top of the drone body facilitates signal reception for the navigation unit and provides space for the buffer mounting mechanism, effectively protecting the navigation unit.

[0012] The navigation device assembly includes a navigation device body, and the exterior of the navigation device body is provided with claws. The claws are used to connect with the buffer mounting mechanism to achieve a stable installation of the navigation device body, and at the same time facilitate the transmission of vibration energy during the buffering process.

[0013] The buffer mounting mechanism includes a mounting plate, which is connected to the drone body by a fixing bolt to ensure a secure connection. A buffer cover is fixed to the bottom of the mounting plate, and multiple extension covers are fixed to the outer side of the buffer cover. A fixing tube is fixed to the side of the extension cover closest to the mounting plate, and a telescopic channel is provided inside the fixing tube. A telescopic rod is slidably connected within the telescopic channel, passing through the mounting plate and fixedly connected to a connector, which is fixedly connected to a claw. This structural design allows the navigator body to slide within the telescopic channel via the telescopic rod, thereby buffering vibration energy and protecting the navigator body when it encounters vibration during drone flight through the extension and retraction of the telescopic rod.

[0014] The buffer base and the extension cover are jointly equipped with a pressure buffer mechanism. The pressure buffer mechanism includes a central pressure buffer chamber located within the buffer base, and branch pressure buffer chambers connected to the central pressure buffer chamber located within the extension cover. A telescopic channel is also connected to the branch pressure buffer chambers. Multiple buffer blocking components are installed within the branch pressure buffer chambers, and a pneumatic pressure regulating buffer assembly is installed within the central pressure buffer chamber. When vibration is transmitted to the buffer mounting mechanism, the fluid within the pressure buffer mechanism (such as hydraulic oil or gas; this application does not explicitly limit the fluid type, and it can be selected according to actual needs) flows between the central pressure buffer chamber, the branch pressure buffer chambers, and the telescopic channel. The buffer blocking components and the pneumatic pressure regulating buffer assembly respectively generate resistance to the fluid flow and regulate the pressure, further buffering vibration energy and improving the buffering effect.

[0015] In a preferred embodiment of the present invention, multiple extension arms are fixedly mounted on the side edges of the drone body, and each extension arm is fixedly mounted with a motor assembly. The output end of the motor assembly is fixedly connected to a wing. The extension arms, motor assembly, and wing are configured to provide power and flight control for the drone.

[0016] In a preferred embodiment of the present invention, a battery pack is fixedly mounted on the extension arm. The battery pack provides power to the various components of the drone, ensuring that the drone can fly continuously.

[0017] In a preferred embodiment of the present invention, the buffer blocking member includes a blocking plate, which is fixedly connected to the inner wall of the support pressure buffer chamber. A liquid permeable hole is formed through the blocking plate, and multiple liquid permeable slits are formed through the blocking plate at the edges of the liquid permeable hole. This structural design causes the fluid to be blocked and diverted by the liquid permeable hole and liquid permeable slits when passing through the blocking plate, increasing the resistance to fluid flow and thus enhancing the buffering effect.

[0018] As a preferred embodiment of the present invention, the baffle plate is made of silicone material. Silicone material has good elasticity and flexibility, enabling it to absorb vibration energy during buffering, while its excellent sealing performance helps maintain the pressure stability of the fluid within the pressure buffer mechanism.

[0019] In a preferred embodiment of the present invention, the air pressure adjustment and buffer assembly includes an air pressure cover, which is fixedly connected to the interior of a buffer base. The air pressure cover is filled with air, and multiple air pressure heads are fixedly mounted on the outer side of the air pressure cover. The interior of each air pressure head is hollow and connected to the interior of the air pressure cover. When the pressure within the pressure buffer mechanism changes, the air inside the air pressure cover is regulated by the air pressure heads, further buffering vibration energy and improving the buffering effect.

[0020] As a preferred embodiment of the present invention, the pressure shroud is formed by plastic injection molding, and the pressure head is made of silicone material. The plastic injection-molded pressure shroud has a certain strength and stability, and can withstand the internal air pressure; the silicone material pressure head has good elasticity and sealing properties, facilitating the realization of air pressure regulation function.

[0021] In a preferred embodiment of the present invention, a sealing ring is provided at the connection between the telescopic rod and the telescopic channel. The sealing ring prevents fluid leakage within the pressure buffer mechanism, ensuring the normal operation of the buffer mechanism.

[0022] The present invention has the following advantages: 1. This invention, through the synergistic effect of a buffer mounting mechanism and a pressure buffer mechanism, can significantly reduce the impact of UAV vibrations on the navigation system during flight. The sliding of the telescopic rod within the telescopic channel, along with the fluid flow and pressure regulation within the pressure buffer mechanism, jointly absorbs and disperses vibration energy, reducing the impact on the navigation system and improving its stability and service life.

[0023] 2. By incorporating buffer components and a pressure-adjusting buffer assembly, the pressure buffer mechanism maintains a good buffering effect under different vibration intensities and frequencies. The coordinated operation of the liquid permeable holes and slits in the baffle plate, as well as the pressure hood and pressure head, can automatically adjust the buffering force according to the vibration conditions, improving the stability and reliability of the buffering effect.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0034] Please see Figure 1-7 A drone structure equipped with a navigation system is disclosed. The navigation mounting assembly 4 includes a navigation system assembly 8 located on top of the drone body 1. The navigation system assembly 8 is connected to the drone body 1 via a buffer mounting mechanism 7. Positioning the navigation system assembly 8 on top of the drone body 1 offers two advantages: firstly, it facilitates signal reception by the navigation system, ensuring accurate navigation and positioning; secondly, it provides ample space for the buffer mounting mechanism 7, thereby effectively buffering and protecting the navigation system and reducing the impact of vibrations during flight.

[0035] Multiple extension arms 2 are fixedly mounted on the side edges of the drone body 1. Each extension arm 2 is equipped with a motor assembly 6, and the output end of the motor assembly 6 is fixedly connected to a wing 3. The extension arms 2, motor assembly 6, and wing 3 provide power and flight control for the drone. A battery pack 5 is fixedly mounted on the extension arms 2. The battery pack 5 provides power to all components of the drone, ensuring continuous flight. The core of the navigation component 8 is the navigation body 10, and the external claw 11 plays a crucial connecting role. The claw 11 is connected to the buffer mounting mechanism 7, allowing the navigation body 10 to be securely mounted on the drone. During flight, when encountering vibrations, the claw 11 also facilitates the transfer of vibration energy to the buffer mounting mechanism 7, laying the foundation for subsequent buffering operations.

[0036] The buffer mounting mechanism 7 includes a mounting plate 9, which is securely connected to the UAV body 1 via a fixing bolt 12, ensuring a reliable connection between the entire buffer structure and the UAV body 1. A buffer base cover 14 is fixed to the bottom of the mounting plate 9, and multiple extension covers 15 are provided on the outer side of the buffer base cover 14. A fixing tube 16 is provided on the side of the extension cover 15 near the mounting plate 9, and a telescopic channel 18 is provided inside the fixing tube 16. A telescopic rod 17 is slidably connected in the telescopic channel 18. The telescopic rod 17 passes through the mounting plate 9 and is fixedly connected to a connector 13, which in turn connects to a claw 11 on the outside of the navigator body 10. This structural design allows the navigator body 10 to slide flexibly within the telescopic channel 18 using the telescopic rod 17. When the UAV encounters vibration during flight, the telescopic rod 17 can buffer the vibration energy through its extension and retraction, thereby protecting the navigator body 10 from excessive vibration impact.

[0037] The buffer base 14 and the extension shroud 15 together form a pressure buffer mechanism. This mechanism includes a central pressure buffer chamber 19 located within the buffer base 14, and a branch pressure buffer chamber 20 within the extension shroud 15 that communicates with the central pressure buffer chamber 19. The telescopic channel 18 is also interconnected with the branch pressure buffer chamber 20. The branch pressure buffer chamber 20 contains multiple buffer stops 21, while the central pressure buffer chamber 19 contains a pneumatic pressure regulating buffer assembly 22. When vibration is transmitted to the buffer mounting mechanism 7, the fluid within the pressure buffer mechanism (the fluid type can be selected according to actual needs, such as hydraulic oil or gas) flows between the central pressure buffer chamber 19, the branch pressure buffer chamber 20, and the telescopic channel 18.

[0038] The buffer baffle 21 is composed of a baffle plate 25, which is fixedly connected to the inner wall of the support pressure buffer chamber 20. A liquid permeable hole 26 is formed through the baffle plate 25, and multiple liquid permeable slits 27 are also formed through the baffle plate 25 at the edges of the liquid permeable hole 26. This unique structural design causes the fluid to be blocked and diverted by the liquid permeable hole 26 and liquid permeable slits 27 when passing through the baffle plate 25, thereby significantly increasing the resistance to fluid flow and further enhancing the buffering effect. Meanwhile, the baffle plate 25 is made of silicone material. The good elasticity and flexibility of silicone allow it to effectively absorb vibration energy during the buffering process, and its excellent sealing performance helps maintain the pressure stability of the fluid within the pressure buffer mechanism.

[0039] The air pressure adjustment buffer assembly 22 consists of an air pressure cover 23 and multiple air pressure heads 24 on its outer side. The air pressure cover 23 is made of plastic injection molding and is fixedly connected to the inside of the buffer base cover 14, and is filled with air. The air pressure heads 24 are made of silicone material, are hollow inside, and are connected to the inside of the air pressure cover 23. When the pressure inside the pressure buffer mechanism changes, the air inside the air pressure cover 23 can be pressure-regulated through the air pressure heads 24, further buffering vibration energy and improving the buffering effect. The plastic injection-molded air pressure cover 23 has a certain strength and stability and can withstand the internal air pressure, while the silicone air pressure heads 24, with their good elasticity and sealing properties, will deform under pressure when the external pressure increases, facilitating precise air pressure regulation.

[0040] To prevent fluid leakage within the pressure buffer mechanism and ensure its normal operation, a sealing ring is specifically installed at the connection between the telescopic rod 17 and the telescopic channel 18. The sealing ring effectively prevents fluid from seeping out of the connection, ensuring the integrity and reliability of the pressure buffer mechanism.

[0041] When the drone takes off and flies in the air, vibrations are generated due to factors such as motor operation and airflow. The vibrations are transmitted through the drone body 1 to the mounting plate 9, and then to the buffer base cover 14 and the extension cover 15.

[0042] At this point, the fluid within the pressure buffer mechanism begins to flow. Within the branch pressure buffer chamber 20, the fluid is blocked and diverted by the liquid permeation holes 26 and liquid permeation slits 27 of the baffle plate 25, increasing flow resistance and thus absorbing some of the vibration energy. Simultaneously, the air pressure regulating buffer assembly 22 within the central pressure buffer chamber 19 adjusts the air pressure according to pressure changes. For example, when vibration causes a pressure increase within the pressure buffer mechanism, the air pressure head 24 is compressed and deformed, mitigating the pressure change and further buffering the vibration energy.

[0043] The telescopic boom 17 extends and retracts within the telescopic channel 18 according to vibration conditions, absorbing and dispersing vibration energy through its own extension and retraction motion, protecting the navigator body 10 from excessive vibration impact. Throughout the flight, the buffer mounting mechanism 7 and the pressure buffer mechanism work together to ensure that the navigator can operate stably and is not significantly affected by vibration.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
