Description

Technical Field

[0001] This utility model relates to the field of drone frame technology, and in particular to a drone frame structure that can be hoisted and freed from trouble. Background Technology

[0002] In recent years, drone technology has developed rapidly, demonstrating enormous potential in numerous fields such as logistics, disaster relief, and geographic surveying. However, the current drone frame structures on the market have significant limitations, making it difficult to meet the increasingly diverse mission requirements.

[0003] In hoisting operations, most drone frames lack precise stress detection and dynamic adjustment mechanisms. During hoisting, the inability to perceive changes in stress in all directions in real time makes it difficult to accurately control the hoisting posture, leading to swaying, tilting, or even cargo falling, severely impacting the safety and stability of the operation. Moreover, when drones operate in complex environments, such as encountering strong winds or entangled obstacles, existing frame structures lack effective extrication capabilities, often leaving them to passively await external rescue, significantly limiting the drone's operational range and efficiency.

[0004] Therefore, this application proposes a hoistable unmanned aerial vehicle (UAV) frame structure, providing a new technical solution to address the aforementioned technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a drone frame structure capable of lifting and extricating itself from difficult situations, addressing the aforementioned technical issues. The cargo is hooked to a lifting connecting rod via ropes and hooks, while the lifting frame acts as a limiter on the hooks, effectively ensuring a stable connection between the hooks and the lifting connecting rods, thus guaranteeing the safety of the cargo during lifting. When adjustments or special operations are required, the telescopic function of the lifting connecting rods and the blocking effect of the lifting frame work together to precisely separate the hooks from the lifting connecting rods. When the lifting connecting rods are completely separated from the lifting frame, the cargo can be quickly thrown. This design plays a significant role when drones encounter complex predicaments, such as being stuck by obstacles or needing to quickly reduce their load to escape danger, helping drones to quickly escape and greatly improving their ability to cope with complex environments and their operational efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A drone frame structure for lifting and freeing drones, which is used for drone lifting.

[0008] The specific components of the hoistable and untangle-capable drone frame structure include:

Cargo is hooked to a lifting connecting rod via ropes and hooks, while the lifting frame limits the hooks, effectively ensuring a stable connection between the hooks and the lifting connecting rod, thus guaranteeing cargo safety during lifting. When adjustments or special operations are needed, the telescopic function of the lifting connecting rod and the blocking effect of the lifting frame work together to precisely separate the hooks from the lifting connecting rod. When the lifting connecting rod is completely separated from the lifting frame, cargo can be quickly thrown.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 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 should fall within the protection scope of the present invention.

[0028] As described in the background section, when drones perform tasks in complex environments, such as encountering difficulties like strong winds or being entangled in obstacles, the existing frame structure lacks effective extrication capabilities and often can only passively wait for external rescue, which greatly limits the drone's operating range and efficiency.

[0029] To solve this technical problem, this utility model provides a drone frame structure that can be hoisted and freed from trouble, which is applied to drone hoisting.

[0030] For details, please refer to Figures 1-3 The specific components of the drone frame structure capable of being hoisted and freed from trouble include:

[0031] The drone chassis 1 is fixedly connected to the upper inner side of the drone chassis 1, and the hoisting main beam 2 is fixedly connected to the lower inner side of the hoisting main beam 2. It consists of key components such as the hoisting mechanism 3. All components work together to realize the hoisting and extrication functions of the drone in complex environments.

[0032] The hoisting mechanism 3 includes a hoisting frame 5 and a push rod motor 7. A triaxial force sensor is installed on the inner side of the UAV base frame 1. The detection end of the triaxial force sensor is fixedly connected to a mounting base 4. The hoisting frame 5 and the mounting base 4 are detachably connected. The push rod motor 7 is located on one side of the hoisting frame 5. The end of the push rod motor 7 is fixedly connected to the end of the hoisting main beam 2 through a mounting plate 8. The telescopic end of the push rod motor 7 is detachably equipped with a hoisting connecting rod 9. The hoisting connecting rod 9 is laterally inserted into the hoisting frame 5.

[0033] This utility model provides a drone frame structure capable of being hoisted and extricated from difficult situations. Cargo is hooked to a hoisting connecting rod 9 via ropes and hooks. The hoisting frame 5 acts as a limit for the hooks, effectively ensuring a stable connection between the hooks and the hoisting connecting rod 9, thus guaranteeing the safety of the cargo during hoisting. When adjustments or special operations are needed, the telescopic function of the hoisting connecting rod 9 and the blocking effect of the hoisting frame 5 work together to precisely separate the hooks from the hoisting connecting rod 9. Even more impressively, when the hoisting connecting rod 9 is completely separated from the hoisting frame 5, the hoisted cargo can be quickly thrown. This design plays a crucial role when the drone encounters complex predicaments, such as being stuck by obstacles or needing to quickly reduce its load to escape danger, helping the drone to quickly escape and greatly improving its ability to cope with complex environments and its operational efficiency.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figures 1-3 A frame structure for lifting and freeing unmanned aerial vehicles (UAVs) includes:

[0037] The drone base frame 1 has a hoisting main beam 2 fixedly connected to the upper inner side of the drone base frame 1, and a hoisting mechanism 3 is provided at the lower inner side of the hoisting main beam 2.

[0038] Specifically, the hoisting mechanism 3 includes a hoisting frame 5 and a push rod motor 7. A triaxial force sensor is installed on the inner side of the UAV base frame 1. The detection end of the triaxial force sensor is fixedly connected to a mounting base 4. The hoisting frame 5 and the mounting base 4 are detachably connected. This detachable design facilitates the installation, disassembly, maintenance, and replacement of the hoisting frame 5. The push rod motor 7 is located on one side of the hoisting frame 5. The end of the push rod motor 7 is fixedly connected to the end of the hoisting main beam 2 through a mounting plate 8 to ensure the stability of the push rod motor 7 during operation. The telescopic end of the push rod motor 7 is detachably equipped with a hoisting connecting rod 9, which is laterally inserted into the hoisting frame 5.

[0039] Furthermore, the hoisting frame 5 is arranged in an m-shape. This shape design can provide more stable structural support and at the same time create two independent hook compartments. The hoisting frame 5 is connected and fixed to the mounting base 4 by fixing bolt 6. The fixing bolt 6 is located at the top of the inner side of the two grooves of the hoisting frame 5, which further enhances the stability of the connection.

[0040] Furthermore, the telescopic end of the push rod motor 7 is provided with a connecting groove 10, and the hoisting connecting rod 9 is inserted into the connecting groove 10 for connection. The hoisting connecting rod 9 and the connecting groove 10 are connected and fixed by fixing bolts 11. This connection method makes the connection between the hoisting connecting rod 9 and the push rod motor 7 firm and reliable, and can withstand greater tensile force during hoisting, ensuring the safety of hoisting operations.

[0041] In actual operation, the triaxial force sensor can detect the force in each direction in real time during hoisting and feed the data back to the UAV's control system. Based on this data, the control system precisely controls the push rod motor 7, adjusting the position and tension of the hoisting connecting rod 9 to achieve stable and safe hoisting operations. When the UAV encounters a situation requiring escape in complex environments, it can achieve escape by properly controlling the hoisting mechanism 3, using external force or adjusting its own attitude.

[0042] Example 2:

[0043] The hoistable and untangle-resistant drone frame structure provided in Embodiment 1 is further optimized, specifically, as follows: Figures 4-5 As shown, a multi-functional bracket 12 can be installed on the lower part of the drone base frame 1 for temporary fixation of other components, which provides convenience for the drone to carry additional equipment or tools during mission execution.

[0044] Specifically, the multi-functional bracket 12 includes a fastener 13, which is fastened to the drone base frame 1. To ensure the stability and accuracy of the fastening, a limiting protrusion 14 is fixedly connected to the drone base frame 1. The fastener 13 is provided with a limiting through hole 15 that cooperates with the limiting protrusion 14, which is used to limit the fastener 13 after it is fastened to the drone base frame 1. When the fastener 13 is fastened to the drone base frame 1, the limiting protrusion 14 is inserted into the limiting through hole 15, which plays a limiting role and prevents the fastener 13 from shaking or falling off during the flight of the drone.

[0045] A clamp 16 is fixedly connected to the outer side of the fastener 13. A clamping groove 17 is provided on the inner side of the clamp 16 for clamping components that require temporary fixation. A fastening component 18 is provided on the side of the clamp 16 away from the fastener 13 for adjusting the tightness of the clamping groove 17. By rotating the fastening component 18, the size of the clamping groove 17 can be changed to accommodate components of different sizes. For example, when fixing a cylindrical component with a large diameter, the fastening component 18 can be tightened to reduce the size of the clamping groove 17 and tightly clamp the component; conversely, when fixing a component with a small diameter, the fastening component 18 can be loosened to adjust the size of the clamping groove 17.

[0046] Through the aforementioned structural design, the multi-functional bracket 12 adds the ability to temporarily fix other components, greatly improving the practicality and adaptability of the drone and enabling it to play a role in a wider range of mission scenarios. For example, during rescue missions, the multi-functional bracket 12 can be used to fix rescue equipment; during environmental monitoring missions, additional monitoring instruments can be carried.

[0047] Example 3:

[0048] The hoistable and untraceable drone frame structure provided in Embodiment 1 is further optimized. Specifically, it also includes a control system for the hoistable and untraceable drone frame structure.

[0049] The control system is equipped with a light control module, which can control the opening and closing of relays by sensing changes in light. When specific light conditions are met, the light control module sends a corresponding signal to drive the relays to open or close, thereby achieving on / off control of the relevant circuits.

[0050] Meanwhile, the system is equipped with a two-way relay optocoupler isolation module. This module receives light control signals from the light control module and precisely controls the opening and closing of the electric actuator. The optocoupler isolation design effectively avoids electrical interference, ensures the stability and accuracy of signal transmission, and enables the electric actuator to operate according to preset requirements, providing power support for the unmanned aerial vehicle (UAV) frame structure to escape from difficult situations.

[0051] To enhance the system's alerting capabilities, a buzzer is also installed. When the buzzer receives a signal from the light-controlled switch, it immediately begins to sound. This buzzing alert provides timely feedback to the operator regarding the system status during operation, reminding them to pay attention to relevant actions or abnormal situations.

[0052] In terms of control, the system is equipped with a main switch for powering on and off the overall control system, and is a key control component for system startup and shutdown. In addition, a manual switch is provided, allowing operators to directly control the opening and closing of the push rod. This manual control method provides the system with flexible operating options, ensuring the normal operation of the push rod in special circumstances or when manual intervention is required.

[0053] To ensure the safe operation of the system, a fuse is also installed. The fuse can automatically melt and disconnect the circuit when an abnormal overcurrent occurs, preventing equipment damage or even fire caused by overcurrent, thus providing reliable safety protection for the entire hoistable and untangle-resistant UAV frame structure control system.
