They have undergone multiple stages of iteration, from basic adaptation to technological integration, becoming the core pillars supporting their application in strategic fields such as military reconnaissance, emergency communication, and environmental monitoring. This article will systematically review the technological origins, development paths, and current technological levels of each key component, revealing the underlying logic of technological evolution.

[0003] However, when the existing device is in use, the wind resistance can cause the connection between the drone and its cable to loosen or fall off, thus affecting the normal operation of the device. Utility Model Content

[0004] This invention provides a component for a long-endurance tethered unmanned aerial vehicle (UAV) to solve the problem that, during use, wind resistance can cause the UAV to loosen or detach from its connecting cable, thus affecting the normal operation of the device.

[0005] This utility model provides the following technical solution: a component for a long-endurance tethered unmanned aerial vehicle (UAV), including a UAV body and further comprising: a sliding assembly disposed on one side of the UAV body, the sliding assembly including a mounting frame, a guide rod, two sets of compression springs, a limiting frame, a snap-fit ​​component, and a compression bolt; connecting rods disposed on both sides of the UAV body, each of the two sets of connecting rods having two sets of first buffer assemblies on one side, each of the four sets of first buffer assemblies including a positioning block and a connecting spring; and second buffer assemblies disposed on the bottom surface of the two sets of connecting rods, each of the two sets of second buffer assemblies including two sets of moving rods, two sets of damping springs, two sets of moving cylinders, and a fixing plate.

[0006] As a preferred technical solution of this utility model, the mounting frame is fixedly connected to one side of the UAV body, a guide rod is fixedly connected inside the mounting frame, two sets of compression springs are sleeved on the outside of the guide rod, one end of the two sets of compression springs is fixedly connected to a limit frame, a snap-fit ​​component is provided on one side of the limit frame, and a compression bolt is rotatably connected to the rear side of the limit frame.

[0007] As a preferred embodiment of this utility model, all four sets of positioning blocks are disposed on one side of the two sets of connecting rods, and a connecting spring is fixedly connected to one side of each of the two or four sets of positioning blocks.

[0008] As a preferred embodiment of this utility model, the four sets of moving rods are all arranged on the bottom surface of the two sets of connecting rods, one end of each of the four sets of moving rods is fixedly connected to a damping spring, one end of each of the four sets of damping springs is fixedly connected to a moving cylinder, and one end of each of the four sets of moving cylinders is fixedly connected to two sets of fixing plates.

[0009] As a preferred technical solution of this utility model, the surface of the drone body is provided with a limit rod, and two sets of power supply bodies are slidably connected inside the drone body.

[0010] As a preferred embodiment of this utility model, a power connector is provided on one side of the drone body, and a connecting wire is fixedly connected to one end of the power connector.

[0013] Compared with the prior art, this utility model provides a component for a long-endurance tethered unmanned aerial vehicle (UAV), which has the following beneficial effects: 1. This long-endurance tethered UAV component, through the setting of the sliding assembly, allows the connecting cable to be placed inside the mounting frame during use. The snap-fit ​​component limits its position, and then the compression bolt is rotated to compress and fix the connecting cable. When the connecting cable encounters wind resistance, the connecting cable moves the limiting frame. When the limiting frame moves, the compression spring deforms to absorb the impact force from the wind resistance, preventing the connecting cable from breaking or loosening due to excessive instantaneous force. At the same time, under the action of the guide rod, the limiting frame can only move in a preset direction, ensuring that the connecting cable is always within the reasonable limit range of the mounting frame, maintaining the stability and reliability of the overall connection of the component.

[0014] 2. This long-endurance tethered UAV component, through the setting of the first and second buffer components, ensures that during landing, the fixed plate first contacts the ground. At this time, the moving rod slides inside the moving cylinder, and the damping spring deforms to initially buffer the impact force. The connecting rod rotates inside the UAV body, and the connecting spring is in a stretched state, further buffering the impact force. This significantly weakens the impact force on the UAV body during landing, effectively avoiding vibration damage to the precision components inside the UAV body caused by rigid impact, and ensuring the structural stability and equipment safety of the UAV during landing.

[0017] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model discloses a component for a long-endurance tethered unmanned aerial vehicle (UAV), including a UAV body 1, and further including: a sliding assembly 2 disposed on one side of the UAV body 1, the sliding assembly 2 including a mounting frame 201, a guide rod 202, two sets of compression springs 203, a limiting frame 204, a snap-fit ​​component 205, and a compression bolt 206; connecting rods 3 disposed on both sides of the UAV body 1, each of the two sets of connecting rods 3 having two sets of first buffer assemblies 4 disposed on one side, each of the four sets of first buffer assemblies 4 including a positioning block 401 and a connecting spring 402; and second buffer assemblies 5 disposed on the bottom surface of the two sets of connecting rods 3, each of the two sets of second buffer assemblies 5 including two sets of moving rods 501, two sets of damping springs 502, two sets of moving cylinders 503, and a fixing plate 504.

[0019] Specifically, the mounting frame 201 is fixedly connected to one side of the UAV body 1. A guide rod 202 is fixedly connected inside the mounting frame 201. Two sets of compression springs 203 are sleeved on the outside of the guide rod 202. One end of the two sets of compression springs 203 is fixedly connected to a limit frame 204. A snap-fit ​​part 205 is provided on one side of the limit frame 204. A compression bolt 206 is rotatably connected to the rear side of the limit frame 204.

[0020] In this embodiment, during use, the connecting wire 9 is placed inside the mounting frame 201, and the snap-fit ​​205 limits the mounting frame 201. At this time, the compression bolt 206 is rotated to fix the connecting wire 9. Under the action of wind resistance, the connecting wire 9 drives the limiting frame 204 to move on the guide rod 202. At this time, the compression spring 203 deforms, thereby preventing the connecting wire 9 from breaking or loosening due to excessive instantaneous force.

[0021] Specifically, all four sets of positioning blocks 401 are set on one side of the two sets of connecting rods 3, and a connecting spring 402 is fixedly connected to one side of each of the two sets of positioning blocks 401.

[0022] In this embodiment, the positioning block 401 is used to deform the connecting spring 402, and the connecting spring 402 is used to buffer the impact force generated by the device.

[0023] Specifically, all four sets of moving rods 501 are set on the bottom surface of the two sets of connecting rods 3. One end of each of the four sets of moving rods 501 is fixedly connected to a damping spring 502. One end of each of the four sets of damping springs 502 is fixedly connected to a moving cylinder 503. One end of each of the four sets of moving cylinders 503 is fixedly connected to two sets of fixing plates 504.

[0024] In this embodiment, the fixed plate 504 is used to contact the bottom surface. When the UAV body 1 contacts the bottom surface, the moving rod 501 slides in the moving cylinder 503, and the damping spring 502 deforms to provide initial cushioning, which can prevent damage to the UAV when it lands.

[0025] Specifically, the surface of the drone body 1 is provided with a limit rod 6, and two sets of power supply bodies 7 are slidably connected inside the drone body 1.

[0026] Specifically, a power connector 8 is provided on one side of the drone body 1, and a connecting wire 9 is fixedly connected to one end of the power connector 8.

[0027] In this embodiment, the power connector 8 is used to connect the power supply body 7 to the drone body 1 to supply power, and the connecting cable 9 is used to connect the drone body 1 to the bottom power supply, etc.

[0028] Specifically, two sets of positioning rods 10 are fixedly connected to both sides of the drone body 1, and two sets of lighting lamps 11 are provided on the surface of the drone body 1.

[0029] Specifically, each of the four sets of positioning rods 10 has a propeller 12 fixedly connected to one end, and a lightweight protective frame 13 is fixedly connected to the outside of each of the four sets of propellers 12.

[0030] The working principle and usage process of this utility model are as follows: When in use, the connecting wire 9 is placed inside the mounting frame 201, and the snap-fit ​​part 205 limits its position. At this time, the compression bolt 206 is rotated, and the compression bolt 206 compresses the connecting wire 9 to fix it. When the connecting wire 9 is subject to wind resistance, the connecting wire 9 drives the limiting frame 204 to move. When the limiting frame 204 moves, the compression spring 203 deforms to absorb the impact force brought by the wind resistance, preventing the connecting wire 9 from breaking or loosening due to excessive instantaneous force. At the same time, under the action of the guide rod 202, the limiting frame 204 can only move in a preset direction, ensuring that the connecting wire 9 is always within the reasonable limiting range of the mounting frame 201, maintaining the stability and reliability of the overall connection of the components. During landing, the fixed plate 504 first contacts the ground. At this time, the moving rod 501 slides inside the moving cylinder 503, and the damping spring 502 deforms to initially buffer the impact force. The connecting rod 3 rotates inside the UAV body 1, and the connecting spring 402 is in a stretched state to further buffer the impact force. This greatly reduces the impact force on the UAV body 1 during landing, effectively avoiding vibration damage to the precision components inside the UAV body 1 caused by rigid impact, and ensuring the structural stability and equipment safety of the UAV during landing.

[0031] In summary, this long-endurance tethered UAV component, through the arrangement of the sliding component 2, the first buffer component 4, and the second buffer component 5, can prevent the connecting line 9 from becoming loose due to wind resistance, while ensuring the stability of the device during landing.
