[0056]

[0057] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0058] 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. Well-known modules, units, and their connections, links, communications, or operations are not shown or described in detail. Furthermore, the described features, architectures, or functions can be combined in any way in one or more embodiments. Those skilled in the art should understand that the various embodiments described below are only for illustrative purposes and are not intended to limit the scope of protection of the present invention.

[0059] The drone delivery system consists of a drone and a fixed-point delivery device on its base. During operation, the drone is controlled to fly to a predetermined location, and the fixed-point delivery device is activated to perform the delivery task, thus achieving automated delivery. This equipment is widely used in various fields such as geological monitoring, public safety, power grids, and landscaping. For example, it is used for deploying geological detection equipment, setting up roadblocks, maintaining power facilities, and planting saplings.

[0060] In the precision delivery devices used with drones, a suspension assembly is installed at the bottom of the device to suspend the delivered object, ensuring its suspension and accurate delivery. However, in existing precision delivery devices, the suspension assembly at the bottom can sometimes accidentally open under external force during mission execution, which may cause the object to fail to be accurately delivered to the intended target location.

[0061] The main solution of this application embodiment is: the suspension assembly has a locked state and an open state as the position of the suspension rod changes. The object is suspended in the locked state and released in the open state. Finally, the suspension assembly is driven to switch between the locked state and the open state by the drive assembly. Through the locking function between the drive assembly and the suspension assembly, the suspension assembly can maintain a stable state when it is not driven by the drive assembly and will not be opened under the action of external force.

[0062] This application provides a solution that can significantly improve the accuracy and safety of drone-based targeted deployment.

[0063] It should be understood that the targeted delivery device proposed in this application is used in conjunction with drones to achieve remote targeted delivery, such as targeted delivery from disaster relief locations to the designated rescue sites, ensuring that relief supplies are delivered accurately to the predetermined target areas. Remote targeted delivery refers to the process where an operator installs control equipment at a selected operating location, then establishes a communication connection with the drone via a wireless device, such as WiFi, Bluetooth, 2.4G, or 4G / 5G communication. The drone then establishes a communication connection with the targeted delivery device, ultimately enabling the operator to control the targeted delivery device for delivery.

[0064] Reference Figure 1 In one embodiment of this utility model, the fixed-point delivery device includes a hanging body 10, a suspension assembly 20, and a drive assembly 30, wherein:

[0065] The sling body 10 has a first side and a second side, the first side of which is used to connect to the drone; the suspension assembly 20 is located on the second side of the sling body 10, the suspension assembly 20 includes a suspension rod 21, the suspension assembly 20 has a locked state and an open state as the position of the suspension rod 21 changes, the suspension assembly 20 suspends the delivery object in the locked state and releases the delivery object in the open state; the drive assembly 30 is used to drive the suspension assembly 20 to switch between the locked state and the open state.

[0066] In the targeted delivery device, the sling body 10 can be a frame structure made of a lightweight alloy material to ensure the overall strength and portability of the device. This frame structure is designed with multiple connection points for easy and quick connection to the drone's hook or clamp. Furthermore, the surface of the sling body 10 is coated with a highly reflective material to improve visibility at night or in low-visibility conditions, ensuring that operators can accurately control the drone for delivery.

[0067] The suspension rod 21 of the suspension assembly 20 is telescopic to accommodate rescue supplies of different sizes and shapes. In the locked state, due to the locking function between the drive assembly 30 and the suspension assembly 20, if an external force moves the suspension rod 21, such as by pulling it directly from the locked state to the open state, the one-way locking device between the suspension assembly 20 and the drive assembly 30 will lock due to positional constraints when the suspension rod 21 is pulled from the locked state to the open state, even when not driven by the drive assembly 30. This maintains the stability of the suspension assembly 20 and prevents it from opening under external force, allowing for precise control of the release timing to adapt to different deployment environments and requirements.

[0068] The drive assembly 30 may include a motor and a transmission mechanism. The motor receives signals from the operating device through a control circuit, thereby driving the transmission mechanism to switch the suspension assembly 20 between a locked state and an open state.

[0069] In the fixed-point delivery device, a first side of the suspension body 10 is used for the drone, and a second side is provided with a suspension assembly 20. The suspension assembly 20 includes a suspension rod 21. The suspension assembly 20 has a locked state and an open state as the position of the suspension rod 21 changes. In the locked state, the delivery object is suspended, and in the open state, the delivery object is released. Finally, the suspension assembly 20 is driven by the drive assembly 30 to switch between the locked state and the open state. Through the locking function between the drive assembly 30 and the suspension assembly 20, the suspension assembly 20 can maintain a stable state when it is not driven by the drive assembly 30, so that it will not be opened under the action of external force, which can improve the accuracy and safety of the drone's fixed-point delivery.

[0070] Optionally, refer to Figure 2 , Figure 3 as well as Figure 12 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figure 1 In the embodiment shown, a locking protection structure 31 is connected between the drive assembly 30 and the suspension assembly 20, so that the suspension assembly 20 is released from the locked state under the active action of the drive assembly 30 and is locked under external force.

[0071] In the fixed-point delivery device, a locking protection structure 31 is provided to ensure that the suspension assembly 20 will not be accidentally opened under unexpected external forces, such as wind or impact, thereby preventing unplanned release of the delivered object. The locking protection structure 31 can be mechanical, such as using springs, latching mechanisms, grooved wheels, incomplete gears, cams, or crank-connecting rod structures, or it can be electronic, such as automatically locking the suspension assembly 20 when an abnormal state is detected by a sensor. This greatly improves the delivery efficiency and safety of the UAV in complex environments, and is especially suitable for occasions requiring remote and precise delivery, such as emergency rescue and material resupply.

[0072] Optionally, refer to Figure 4 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figure 2 and Figure 3 In the embodiment shown, the locking protection structure 31 includes a one-way transmission mechanism 311, wherein:

[0073] One end of the one-way transmission mechanism 311 is connected to the drive assembly 30, and the other end of the one-way transmission mechanism 311 is connected to the suspension assembly 20.

[0074] In the fixed-point delivery device, the one-way drive mechanism 311 is designed to allow the drive assembly 30 to drive the suspension assembly 20 under normal operation, but when subjected to unexpected external forces, such as wind or impact, the one-way drive mechanism 311 can prevent the suspension assembly 20 from being accidentally opened. This one-way drive mechanism 311 may include a ratchet and pawl structure, or use a clutch and stop device, or a cam, etc., to ensure that the suspension assembly 20 remains in a safe locked state under abnormal conditions, thereby preventing unplanned release of the delivery object.

[0075] Optionally, the one-way transmission mechanism 311 includes a driving rotating element 3111, wherein:

[0076] The active rotating component 3111 rotates forward or backward under the drive of the drive assembly 30 to drive the suspension rod 21 into or out of the locked state.

[0077] The active rotating component 3111 can be a gear, worm gear, or other rotating mechanical part, which controls the opening and closing of the suspension rod 21 through the rotational movement of the drive assembly 30. The rotational direction and force of the active rotating component 3111 are precisely controlled by the drive assembly 30 to ensure that the object can be accurately delivered to the predetermined position during normal delivery operations.

[0078] It should be understood that the one-way transmission mechanism 311 includes at least one of a Geneva wheel, an incomplete gear, a cam, or a crank-connecting rod structure.

[0079] The Geneva structure ensures unidirectional transmission, allowing the drive assembly 30 to drive the suspension rod 21 only in a specific direction. In the opposite direction, due to the Geneva's structural characteristics, the suspension rod 21 remains in its current state and will not change due to external forces or unforeseen circumstances. The incomplete gear structure is designed so that the gears can mesh in one direction but not in another, thus achieving unidirectional transmission. The cam or crank-connecting rod structure controls the movement of the suspension rod 21 through specific geometry and motion trajectories, ensuring that it correctly enters or exits the locked state under the action of the drive assembly 30.

[0080] In practical applications, a suitable one-way transmission mechanism 311 can be selected based on different usage environments and requirements. For example, in situations requiring rapid release of the object, a Geneva structure can be chosen due to its fast response speed; while in environments requiring heavy loads, an incomplete gear structure may be more suitable because of its simple and durable structure. Cam or crank-connecting rod structures may be suitable for applications requiring extremely high release accuracy because they provide more precise control.

[0081] Optionally, refer to Figure 5 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figure 4 In the embodiment shown, when the one-way transmission mechanism 311 includes a cam or crank-connecting rod structure, the fixed-point delivery device also includes a steering limiter 40. The locked state corresponds to the first position of the active rotating member 3111, and the steering limiter 40 restricts the active rotating member 3111 from continuing to rotate forward from the first position.

[0082] In this embodiment, a cam or crank-connecting rod structure is used as the one-way transmission mechanism 311. The steering limiter 40 is provided to ensure that during the deployment process, the active rotating component 3111 cannot continue to rotate forward after reaching the locked state, thereby preventing the suspension rod 21 from accidentally opening due to misoperation or mechanical failure. The steering limiter 40 can be a physical limit block, bolt, spring, or other mechanical device, which functions when the active rotating component 3111 reaches the predetermined position to prevent it from continuing to rotate, ensuring the safety and reliability of the deployment process.

[0083] In the precision delivery device, the design of the steering limiter 40 is crucial. It not only ensures the accuracy of delivery but also improves the stability and reliability of the entire device. In actual operation, operators can precisely control the drone and the precision delivery device by manipulating the equipment, and the steering limiter 40 provides additional safety for this process, ensuring the successful completion of delivery missions in various complex environments.

[0084] Optionally, refer to Figure 6 , Figure 7 as well as Figure 12 In another embodiment of this utility model, a fixed-point delivery device is provided, based on the above... Figure 1 In the embodiment shown, the sling body 10 includes a base frame 11 and a connector 12 disposed above the base frame 11 for connecting to the drone, wherein:

[0085] The suspension rod 21 is located below the base frame 11, and the drive assembly 30 is fixedly connected to the base frame 11 above the suspension rod 21. The suspension rod 21 has a first horizontal section 211, a second horizontal section 212, and at least one vertical section 213. The at least one vertical section 213 is connected vertically to the first horizontal section 211 and the second horizontal section 212 to form a rotary shape. The first horizontal section 211 is connected to the drive assembly 30. When the suspension rod 21 is in the locked state, the suspension rod 21 is located directly below the connector 12.

[0086] The first horizontal section 211, the vertical section 213, and the second horizontal section 212 are connected in sequence to form a rotating structure, which allows the suspension rod 21 to be stably held directly below the connector 12 in the locked state, ensuring the stability of the object before it is released. This design not only improves the reliability of the fixed-point delivery device but also simplifies the structure, making the device lighter, easier to carry, and easier to operate.

[0087] One way to achieve this is by reducing the lateral dimensions and adjusting the center of gravity of the suspended body 10 to make its suspended posture stable.

[0088] Furthermore, the design of the base frame 11 takes into account various factors, including material selection, strength calculations, and compatibility with drones. The base frame 11 typically uses high-strength, lightweight materials, such as carbon fiber or aluminum alloy, to ensure sufficient support without increasing the drone's load. The shape and dimensions of the base frame 11 are carefully designed to accommodate different drone models, ensuring a stable connection and ease of operation.

[0089] Optionally, refer to Figure 8 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figures 1 to 7 In the embodiment shown, the suspension assembly 20 further includes an auxiliary assembly 50, wherein:

[0090] The auxiliary component 50 is located on the periphery of the suspension component 20. The auxiliary component 50 is used to assist the suspension component 20 in maintaining its motion trajectory and reducing resistance when the suspension component 20 is driven by the drive component 30, so that the suspension component 20 can smoothly switch between the locked state and the open state.

[0091] In the suspension assembly 20, the auxiliary component 50 is designed to improve the stability and smoothness of the suspension assembly 20 when switching states. The auxiliary component 50 may include rollers, slide rails, or other components made of low-friction materials, which provide assistance when the suspension assembly 20 moves, reducing friction and resistance between the suspension rod 21 and the suspension body 10. This design not only ensures the accuracy of the suspension assembly 20 switching between locked and open states, but also extends the service life of the device and reduces maintenance costs.

[0092] The addition of the auxiliary component 50 makes the operation of the entire fixed-point delivery device smoother, especially in windy or harsh operating environments, effectively preventing the suspension component 20 from jamming or malfunctioning due to excessive resistance. Furthermore, the material selection and design of the auxiliary component 50 also take into account corrosion resistance and abrasion resistance to meet the challenges of outdoor environments.

[0093] In practical applications, the maintenance and inspection of the auxiliary component 50 are relatively simple. Operators can easily clean and lubricate the auxiliary component 50 during regular inspections of the drone and the delivery device, ensuring that it is always in optimal working condition.

[0094] Optionally, the auxiliary assembly 50 includes an auxiliary support 51 and a plurality of driven wheels 52, wherein:

[0095] The auxiliary support 51 is located on the periphery of the suspension assembly 20; multiple driven wheels 52 are movably arranged in the auxiliary support 51 and rotatably connected to the periphery of the suspension assembly 20; when the suspension assembly 20 is driven by the drive assembly 30, the driven wheels 52 rotate in the direction of movement of the suspension assembly 20 to assist the suspension assembly 20 in switching between the locked state and the open state.

[0096] The auxiliary support 51 may be made of high-strength materials to withstand the impacts and pressures that may be encountered during operation in harsh environments. The driven wheels 52 are typically made of wear-resistant materials such as polyurethane or nylon to ensure good performance over extended periods of use. The layout and number of driven wheels 52 are optimized to provide uniform and effective assistance during the movement of the suspension assembly 20, thereby reducing friction between the suspension rod 21 and the suspension body 10 and improving the overall responsiveness and reliability of the device.

[0097] In the fixed-point delivery device, the addition of the auxiliary component 50 not only improves the device's mechanical performance but also enhances its adaptability to complex environments. For example, in severe weather conditions such as sandstorms, rain, and snow, the auxiliary component 50 can effectively prevent the suspension component 20 from becoming obstructed due to dust or ice accumulation, ensuring the smooth execution of the delivery mission. Whether used for emergency rescue, material resupply, or other occasions requiring remote delivery, this device provides reliable support, greatly improving the success rate and safety of UAV delivery missions.

[0098] Optionally, refer to Figure 9 as well as Figure 12 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figures 1 to 7 The embodiment shown further includes a housing 60, a top cover 70, and a bottom cover 80, wherein:

[0099] The housing 60 is arranged around the circumference of the hanging body 10, and the housing 60 has an upper side and a lower side; the top cover 70 is located on the upper side of the housing 60; the bottom cover 80 is located on the lower side of the housing 60; the bottom cover 80, the housing 60 and the top cover 70 are sealed together or integrally formed to form a receiving chamber, and the drive assembly 30 is housed in the receiving chamber.

[0100] The bottom cover 80, housing 60, and top cover 70 can all be made of high-strength and weather-resistant materials. The bottom cover 80, housing 60, and top cover 70 can be integrally molded or sealed with a sealing ring to protect the internal drive assembly 30 from external environmental influences such as rain and dust. The design of the top cover 70 and bottom cover 80 considers both sealing and strength, ensuring good protection under various climatic conditions. Furthermore, the housing 60, top cover 70, and bottom cover 80 can be connected by threads, snap-fit ​​connections, or other reliable fixing methods to ensure they do not loosen or detach during transportation and use.

[0101] Optionally, refer to Figure 9 and Figure 10 Another embodiment of this utility model provides a fixed-point delivery device, based on the above... Figures 1 to 7 In the embodiment shown, the lower side of the bottom cover 80 has a first suspension member 81 and a second suspension member 82 disposed opposite to each other, wherein:

[0102] The first suspension member 81 is provided with a first locking hole 83, and the second suspension member 82 is provided with a second locking hole 84 opposite to the first locking hole 83. The end of the second horizontal section 212 passes through the first locking hole 83 and the second locking hole 84 in sequence to form a locking space between the first suspension member 81 and the second suspension member 82. The vertical section 213 is provided inside the first suspension member 81, and the first locking hole 83 is provided with a sealing ring.

[0103] Both the first suspension member 81 and the second suspension member 82 can be housings 60, and are positioned opposite each other on the underside of the bottom cover 80. A suspension channel is defined between the first suspension member 81 and the second suspension member 82, and a suspension rod 21 passes through the space between the first suspension member 81 and the second suspension member 82 to form a locking space. This design not only ensures the stability of the suspension assembly 20 in the locked state, but also effectively prevents the intrusion of moisture and dust through the sealing ring, protecting the internal drive assembly 30. The structural design of the first suspension member 81 and the second suspension member 82 takes into account strength and durability, ensuring good performance during long-term use. In addition, by setting a locking space between the first suspension member 81 and the second suspension member 82, the safety of the suspension assembly 20 can be greatly improved, preventing the unexpected release of the suspension rod 21 due to accidental collisions or vibrations during flight. This design improves the flexibility and adaptability of the point-to-point delivery device. Whether in urban rescue, agricultural monitoring, or reconnaissance, this point-to-point delivery device can provide stable and reliable delivery performance, meeting the needs of use in various complex environments.

[0104] Optionally, refer to Figures 11 to 13 In another embodiment of this utility model, a fixed-point delivery device is provided, based on the above... Figures 1 to 7 The embodiment shown further includes a remote control module 91 and a communication transfer module 92, wherein:

[0105] The remote control module 91 is located inside the sling body 10 and is used to remotely control the sling body 10 for targeted deployment. It includes a wired connection module for connecting to the UAV and a wireless connection module for connecting to the remote control module 91. The communication transfer module 92 is located on the UAV and is used to receive control signals transmitted by the UAV and transmit them to the remote control module 91 through the wireless connection module to control the targeted deployment of the sling body 10.

[0106] The remote control module 91 can be a microprocessor or microcontroller that can receive instructions from the operator and convert them into control signals to drive the drive component 30 to perform the delivery action.

[0107] The communication adapter module 92 is responsible for establishing a stable communication link between the drone and the remote control module 91. The communication adapter module 92 is mounted on the drone and connects to it via a wired connection module, while its wireless connection module communicates with the remote control module 91 of the targeted delivery device. This design allows operators to precisely control the delivery actions of the targeted delivery device from a distance, by connecting to the remote control module 91 through the drone's sensing and control system, greatly improving operational flexibility and safety.

[0108] In practice, the combined use of the remote control module 91 and the communication transfer module 92 allows operators to remotely control the delivery process via wireless signals from a location far from the drone and the designated delivery device. This remote control capability greatly improves the flexibility and safety of drone delivery missions, especially when delivery needs to be carried out in dangerous or hard-to-reach areas.

[0109] Optionally, the targeted delivery device also includes a vision module and a remote control, wherein:

[0110] The vision module is located on the hanging body 10; the remote controller is connected to the drone or the remote control module 91 and is used by the operator to remotely control the suspension component 20 to be deployed at a fixed point.

[0111] The vision module can be installed at the front end of the mounting body 10 to capture and transmit image information of the deployment area to the operator's control interface in real time. Through the vision module, the operator can clearly see the real-time situation of the deployment area, thus making more accurate deployment decisions. The vision module typically includes a camera and an image processing unit, capable of providing high-resolution images and transmitting them wirelessly to the operator's remote control or ground control station.

[0112] As the direct interaction tool between the operator and the drone and the targeted delivery device, the remote controller is designed with ease of use and functionality in mind. Remote controllers are typically equipped with a touchscreen or physical buttons for sending control commands to the drone and the targeted delivery device. Some advanced remote controllers may also integrate advanced functions such as map display, flight data recording and analysis to help operators better plan and execute missions.

[0113] In practical applications, the combined use of the vision module and remote controller provides operators with powerful visual support and control capabilities. Operators can utilize the image information provided by the vision module, combined with the remote controller's functions, to precisely control the drone to reach the designated delivery point and release the payload at the optimal time. This combination of technologies not only improves delivery accuracy but also enhances operational safety and efficiency, its value being particularly significant in complex terrain or emergency rescue missions.

[0114] Optionally, the fixed-point delivery device also includes an adjustment mechanism and a switch 93 located on the suspension body 10, wherein:

[0115] The adjustment mechanism is used to adjust the relative position of the suspending body 10 and the drone; and the switch 93 is used to manually control the drive assembly 30 to drive the suspension assembly 20 from the locked state to the open state.

[0116] The adjustment mechanism may include a robotic arm, winch, or reel; the switch 93 located on the suspension body 10 can be a physical button. Operators can precisely adjust the distance and angle between the suspension body 10 and the drone using the adjustment mechanism to adapt to different deployment needs and environmental conditions, enabling targeted deployment to unsuitable or inconvenient target locations such as slopes, tall grass, and narrow gaps. The adjustment mechanism is designed with ease and precision in mind, ensuring quick and accurate adjustments under various complex conditions.

[0117] The switch 93 provides operators with the ability to manually control the device in emergencies. In the event of a failure of the automatic control system or a need to immediately switch the state of the suspension assembly 20, operators can respond quickly via switch 93 to manually drive the suspension assembly 20 from the locked state to the open state, ensuring the smooth execution of the deployment task. The switch 93 is designed to be simple and intuitive, making it easy for operators to quickly identify and use in stressful or complex situations.

[0118] The addition of the adjustment mechanism and switch 93 makes the operation of the targeted delivery device more flexible and safer. Operators can quickly adjust the device status according to actual task requirements and site conditions to ensure the accuracy and safety of delivery. In addition, these manual control functions also provide additional redundant control means for the UAV targeted delivery device, improving the reliability of the entire system.

[0119] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
