Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically to a UAV-borne radar mount structure with shock absorption function. Background Technology

[0002] With the rapid development of drone technology, its applications in military and civilian fields are becoming increasingly widespread, such as reconnaissance, surveying and mapping, logistics, and environmental monitoring. However, drones are affected by various factors during flight, resulting in vibrations and impacts. These vibrations not only affect flight stability but may also damage precision equipment such as onboard radar, reducing its performance and lifespan.

[0003] Traditional UAV-borne radar pylon structures typically employ rigid connections, which cannot effectively isolate vibrations and shocks during flight. For example, when flying in complex environments, factors such as airflow fluctuations, gusts, and uneven ground can intensify UAV fuselage vibrations, thereby affecting radar imaging quality and measurement accuracy. Furthermore, during UAV landing, environmental factors such as gusts or uneven ground, as well as human error, can result in an uneven landing process, causing severe vibrations that pose a significant threat to the UAV's internal precision electronic equipment.

[0004] To address this issue, some vibration damping designs have emerged in existing technologies, such as using rubber vibration isolators, composite spring vibration dampers, and damping foam to reduce vibration. However, most of these vibration damping methods have certain limitations, such as limited damping effect and material properties being greatly affected by the environment.

[0005] Therefore, developing a novel UAV-borne radar mount structure with shock absorption function is of great significance for improving the flight stability of UAVs and the performance of radar equipment. Utility Model Content

[0006] In view of this, the present invention provides a UAV-borne radar mount structure with shock absorption function, aiming to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A shock-absorbing radar mount structure for unmanned aerial vehicles (UAVs) includes the UAV itself; and also includes:

[0009] A base frame is bolted to the bottom surface of the UAV body, and the lower part of the base frame has a recessed upper mounting groove.

[0010] A towable mesh frame is provided below the base mesh frame, and its edges are connected to the base mesh frame through multiple elastic connectors. The upper part of the towable mesh frame has a recessed lower mounting groove, which corresponds to the upper mounting groove and is used to secure the connection of the airborne radar.

[0011] Through the above technical solution, this utility model, via the elastic connectors between the base frame and the towed frame, and the elastic supports on the towed frame, can effectively absorb and buffer the vibrations and impacts generated during UAV flight, protecting precision equipment such as airborne radar and improving its performance and service life. The base frame is bolted to the UAV body, ensuring a firm and reliable connection that guarantees the stability of the entire pylon structure during flight, preventing loosening or detachment due to vibration or external forces. The structural design of the base frame and towed frame makes the installation and disassembly of the airborne radar more convenient and quick. The corresponding upper and lower mounting slots, along with the cooperation of the elastic supports, enable rapid mounting and fixing of the airborne radar.

[0012] Preferably, in the above-mentioned UAV-borne radar mounting structure with shock absorption function, the base frame is an inverted truncated quadrangular prism structure, and the top edge of the base frame has ear plates for connecting with the UAV body. The inverted truncated quadrangular prism structure of the base frame provides high structural strength and stability, enabling it to better withstand the weight of the airborne radar and various external forces during flight. The ear plate design provides more connection points and a more reliable connection method between the base frame and the UAV body, further enhancing the connection strength between the entire mounting structure and the UAV body, ensuring stability in complex flight environments.

[0013] Preferably, in the above-mentioned UAV-borne radar mounting structure with shock absorption function, the towing mesh frame is composed of a base plate and an annular mesh frame fixed around the edge of the base plate. The lower mounting groove is formed in the middle of the annular mesh frame, and multiple elastic support members are evenly distributed on the top surface of the base plate corresponding to the lower mounting groove. This structure, consisting of a base plate and an annular mesh frame, with multiple elastic support members evenly distributed on the top surface of the base plate corresponding to the lower mounting groove, allows the weight of the airborne radar to be evenly distributed across the elastic support members, avoiding excessive local stress and thus better protecting the airborne radar. The multiple elastic support members increase the contact points and buffer area for shock absorption, further improving the shock absorption performance of the entire mounting structure and enabling more effective absorption and attenuation of vibration and impact energy.

[0014] Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, multiple support seats are evenly distributed and fixed on the top surface of the annular mesh frame. Adjusting bolts are threaded onto each support seat, and elastic support members are fixedly connected to the ends of the adjusting bolts pointing towards the airborne radar. The adjusting bolts threaded onto the support seats can be adjusted according to the size and installation requirements of the airborne radar, allowing the elastic support members to better fit the airborne radar, thereby achieving more precise fixing and more effective shock absorption. This adjustable design allows the mount structure to adapt to different models and sizes of airborne radars, improving the versatility and applicability of the mount and reducing production costs.

[0015] Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, the elastic support member includes two parallel support plates and an X-shaped elastic arc plate connected between the two support plates. The elastic support member adopts a structure of two parallel support plates and an X-shaped elastic arc plate connected between the support plates. This structure has good elasticity and stability, and can generate effective elastic deformation when subjected to external forces, thereby absorbing and buffering vibration and impact energy, and improving the shock absorption effect. The design of the X-shaped elastic arc plate makes the structure of the elastic support member more compact, achieving better shock absorption performance in a limited space, and also contributing to the compact design of the entire mount structure, saving space. Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, the multiple elastic support members on the base plate are arranged in a matrix. The matrix arrangement of the multiple elastic support members on the base plate ensures that the airborne radar receives uniform support in all directions, avoiding deformation or damage caused by uneven force, further improving the installation stability and shock absorption effect of the airborne radar. The matrix arrangement of elastic supports makes the entire trailer frame structure more symmetrical and balanced, which helps to improve the stability and reliability of the entire frame structure and reduce vibration and swaying caused by structural asymmetry.

[0016] Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, the multiple elastic support members on the annular grid are symmetrically arranged. The symmetrical arrangement of the multiple elastic support members on the annular grid ensures that the airborne radar receives balanced support on the annular grid, ensuring uniform force on the airborne radar in all directions, avoiding tilting or swaying caused by uneven force, and improving the working stability and measurement accuracy of the airborne radar. The symmetrical arrangement of the elastic support members makes the entire towing grid structure more stable, enhances the towing grid's resistance to deformation, and better maintains its shape and position stability under external forces, thereby improving the stability and reliability of the entire mount structure.

[0017] Preferably, in the aforementioned UAV-borne radar mount structure with shock absorption function, the adjusting bolt head has an internal hexagonal head. This design makes adjusting the adjusting bolt more convenient and quick. The internal hexagonal structure provides better torque transmission and stability, facilitates adjustment and installation using tools, and improves the assembly efficiency and installation accuracy of the mount. The internal hexagonal design also makes the adjusting bolt head more compact, saving space and contributing to the compact design of the entire mount structure, making it more suitable for space-constrained applications such as UAVs.

[0018] Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, the elastic connector includes a screw, a nut, and a spring; the top end of the screw is fixed to the bottom surface of the base frame, and the bottom end of the screw passes through a through hole in the top surface of the towing frame; the nut is locked to the bottom end of the screw; the spring is sleeved on the screw and pressed against the base frame and the towing frame. The elastic connector, including the screw, nut, and spring, enables an elastic connection between the base frame and the towing frame. When the UAV is subjected to vibration or impact, the spring can undergo elastic deformation, absorbing and buffering external forces, thereby reducing the impact of vibration and impact on the airborne radar and improving the shock absorption effect. The connection method of the screw and nut makes the structure of the elastic connector more robust and reliable, ensuring the connection stability between the base frame and the towing frame, while also fully utilizing the elastic performance of the spring, ensuring the stability and reliability of the shock absorption function of the entire mount structure.

[0019] Preferably, in the above-mentioned UAV-borne radar mount structure with shock absorption function, both the base frame and the towing frame are made of PP or PVC. The use of PP or PVC materials for the base frame and towing frame is lightweight, reducing the overall weight of the mount structure and thus lowering the UAV's flight load, improving its flight performance and endurance. PP or PVC materials also have good corrosion resistance and anti-aging properties, allowing them to adapt to different environmental conditions such as humidity, high temperature, and low temperature, thereby extending the service life of the mount structure and reducing maintenance costs.

[0020] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a UAV-borne radar mount structure with shock absorption function, which has the following beneficial effects:

[0021] 1. Significant Vibration Reduction Performance: Through the design of elastic connectors between the base frame and the towing frame, elastic supports on the towing frame, and X-shaped elastic arc plates, the system effectively absorbs and buffers vibrations and impacts generated during flight, protecting precision equipment such as airborne radar, extending their service life, and improving their performance. The matrix and symmetrical arrangement of the elastic supports further enhances the vibration reduction effect, ensuring that the radar receives uniform support and buffering in all directions.

[0022] 2. Structural Stability and Reliability: The base frame adopts an inverted quadrangular truncated beam structure, which has high strength and stability, and can withstand the weight of the airborne radar and external forces during flight. Through bolted connections, adjusting bolts, internal hexagonal design, and spring buffering of elastic connectors, the robustness and reliability of the entire pylon structure are ensured in complex flight environments.

[0023] 3. Ease of Installation and Maintenance: The design of the mounting structure makes the installation and disassembly of the airborne radar more convenient and quick. The corresponding upper and lower mounting slots, as well as the adjustability of the elastic support, enable rapid locking and fixing. The internal hexagonal design of the adjusting bolts facilitates adjustment and installation using tools, improving assembly efficiency and installation accuracy.

[0024] 4. Adaptability and Versatility: The mounting structure can accommodate airborne radars of different models and sizes. The adjustable bolts allow for flexible adjustment of the position of the elastic support components, meeting the installation requirements of various equipment. The materials chosen for the base frame and the towing frame (PP or PVC) are not only lightweight but also possess excellent corrosion resistance and aging resistance, adapting to diverse environmental conditions.

[0025] 5. Overall Performance Improvement: This pylon structure not only provides shock absorption protection for the airborne radar but also offers shock absorption cushioning during the takeoff and landing of the UAV, improving its flight stability and safety. Through optimized design, such as the matrix-arranged elastic supports and symmetrical structure, the overall performance and reliability of the pylon are further enhanced, making it widely applicable in the field of UAV technology.
