Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an automatic unhooking device for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. In recent years, UAV-related technologies have developed rapidly both domestically and internationally, and they have found wide applications in fields such as aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, and film and television production.

[0003] In the field of disaster relief, drones have been widely used due to their safety, speed, and efficiency. During the process, drones carry relief supplies and, through their built-in cameras, can make timely and accurate assessments of the situation in the disaster area. When they observe people in need of rescue, they can deliver relief supplies accurately and promptly, thus playing a positive role in improving rescue efficiency and ensuring the safety of rescuers and those awaiting rescue.

[0004] Existing drones typically use tow hooks to carry relief supplies, controlling the hooks by transmitting and receiving signals during the process. However, in actual disaster relief, due to the complex and ever-changing environment, equipment interference and malfunctions can occur, sometimes resulting in the hooks opening but supplies failing to be dropped, thus hindering accurate and timely delivery and delaying the best rescue opportunity. Therefore, a release device that can automatically detach supplies after they reach the designated location during disaster relief is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing an automatic unhooking device for drones, which can automatically unhook supplies after they are transported to the rescue site, thus avoiding delays in unhooking and ensuring the normal operation of the drone.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic unhooking device for unmanned aerial vehicles, including a connector, a hinged part is provided below the connector, a first claw and a second claw are respectively hinged and installed through the hinged part, a spring is provided between the backs of the first claw and the second claw, and a hook is provided between the first claw and the second claw. Under the action of the spring and the hook, the first claw and the second claw can be in a retracted state.

[0007] Furthermore, the back of the first claw is provided with a first connecting part, and the back of the second claw is provided with a second connecting part, and a spring is connected through the first connecting part and the second connecting part.

[0008] Furthermore, the hook is hinged to the first claw, and a locking element is provided on the second claw, which cooperates with the hook.

[0009] Furthermore, when the first and second claws are in the retracted state, when a heavy object is hung, the first and second claws can be further retracted under the gravity of the heavy object; when further retracted, the hook and the locking element separate.

[0010] Furthermore, a mounting part is provided above the connector, through which a counterweight is mounted.

[0011] Furthermore, the counterweight is sleeved and installed on the mounting part, and a pressure plate is provided on the counterweight, pressing the counterweight and connecting the pressure plate to the mounting part.

[0012] Furthermore, a lifting ring is installed on the mounting part, the lifting ring passes through the pressure plate and is connected to the mounting part, and the annular end of the lifting ring is located above the pressure plate.

[0013] Furthermore, the counterweight is provided with cushioning cotton, and the cushioning cotton has openings that cooperate with the lifting ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model has a simple structure and is stable and convenient to use. During use, it can achieve stable transportation of materials and automatically detach the materials after they are delivered to the rescue site. It plays a positive role in the efficient conduct of rescue missions and the stable use of drones. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] Embodiments of this utility model:

[0023] like Figure 1-3 As shown, the automatic unhooking device in this embodiment is provided with a connector 1, and a hinge part 11 is provided below the connector 1. The hinge part 11 is hinged to the first claw 4 and the second claw 5 respectively. A first connecting part 41 is provided on the back of the first claw 4, and a second connecting part 51 is provided on the back of the second claw 5. A spring 7 is connected to the first connecting part 41 and the second connecting part 51. A hook 6 is provided between the first claw 4 and the second claw 5, wherein the hook 6 is hinged to the first claw 4. A locking part 52 is provided on the second claw 5, and the locking part 52 cooperates with the hook 6.

[0024] An installation part 12 is provided above the connector 1. A counterweight 2 is sleeved and installed through the installation part 12, and a pressure plate 13 is installed through the installation part 12. The pressure plate 13 presses on the counterweight 2. In this embodiment, the pressure plate 13 and the installation part 12 are fastened together by bolts, and a lifting ring 14 is threadedly connected through the installation part 12. The annular end of the lifting ring 14 is located above the pressure plate 13. A buffer cotton 3 is provided on the counterweight 2. The buffer cotton 3 is glued to the counterweight 2, and an opening is provided on the buffer cotton 3 to cooperate with the lifting ring 14.

[0025] The principle of this utility model is as follows:

[0026] This utility model can be used alone or in conjunction with a drone descent device. The drone descent device is an existing one, such as the Chinese utility model patent: "CN221738077U A Drone Material Descent Device", which is easy for those skilled in the art to understand, so it will not be described in detail.

[0027] Taking the use of a drone descent device as an example, the automatic unhooking device of this utility model is connected to the drone descent device (connected to the drone descent device via the lifting ring 14); when it is necessary to transport goods, firstly open the first claw 4 and the second claw 5, as shown in the attached diagram. Figure 2 In the state shown, place the lifting rope of the material between the first claw 4 and the second claw 5. At this time, pinch the first claw 4 and the second claw 5 together and hang the hook 6 on the locking part 52. Under the action of the spring 7, the hook 6 can be stably hung on the locking part 52. At this time, the steps of hanging the material have been completed.

[0028] The drone is controlled to take off, and it lifts the material descent device and the automatic unhooking device. When the hoisting rope between the automatic unhooking device and the material is taut and begins to bear force, the first claw 4 and the second claw 5 further retract due to the weight of the material. At this time, the hook 6 will automatically separate from the locking part 52 due to the loss of the support of the spring 7, and the hook 6 will be in a natural drooping state. Even if the hook 6 is lost, the first claw 4 and the second claw 5 will still be tightly connected due to the pressure of the weight of the material, and there will be no separation. Thus, the material is hoisted and placed. At this time, the drone takes off, and the pull rope of the material descent device is wound up, thus realizing the transportation process of the material.

[0029] Once the supplies are transported to the designated location, the supplies under the buffer will contact the ground. At this point, the first claw 4 and the second claw 5 will lose the effect of gravity on the supplies. Then, under the action of the spring 7, the first claw 4 and the second claw 5 will open, and the supplies will be transported to the designated location, completing the entire supply transportation process. The control of the drones involved in the above process is a mature existing technology, so it will not be described in detail.
