Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a tethered UAV structure with replaceable batteries. Background Technology

[0002] With the rapid development of drone technology, tethered drones, with their unique advantage of long-term aerial loitering via tether cables, have been widely used in numerous fields such as emergency communication, power line inspection, environmental monitoring, and security surveillance. The core operating mode of tethered drones is to continuously power the aerial drone platform through a ground power supply system via a tether cable, thereby breaking through the endurance bottleneck of traditional battery-powered drones and enabling uninterrupted operation for hours or even tens of hours. This characteristic makes them irreplaceable in scenarios with stringent requirements for operational duration.

[0003] Utility model patent CN218703918U discloses a tethered drone. In this utility model, the bottom of the drone body has two sliding grooves. A hollow movable plate is fixedly connected to sliders at both ends near the sliding grooves. The sliders are slidably connected inside the sliding grooves. A limiting groove is formed on the inner wall of the sliding groove. A limiting block is fixedly connected to the side of the slider near the limiting groove, and the limiting block is slidably connected inside the limiting groove. When the drone body needs to transport items, the size of the space formed by the hollow movable plates on both sides can be changed by moving the position of the hollow movable plates, thereby clamping items of different sizes. This makes it convenient for users to fix items of different sizes to the bottom of the drone body, which is more stable than using ropes to carry items and can minimize the impact of items swinging at the bottom of the drone body on its flight.

[0004] However, when the device is in use, the continuous vibration of the drone body during flight, the pulling force caused by attitude adjustment, and the influence of external airflow disturbances and collisions with foreign objects in the flight environment can lead to a decrease in the stability of the connection between the power cord and the drone interface, which can easily result in loosening, poor contact, or even detachment, thus affecting the use of the drone. Utility Model Content

[0005] This invention provides a tethered drone structure with replaceable batteries to solve the problem that existing devices, when in use, suffer from the continuous vibration of the drone body during flight, the pulling force caused by attitude adjustment, and the influence of external airflow disturbances and collisions with foreign objects in the flight environment. This leads to a decrease in the connection stability between the power cord and the drone interface, which is prone to loosening, poor contact, or even detachment, thus affecting the use of the drone.

[0006] This utility model provides the following technical solution: a tethered drone structure with replaceable batteries, including a drone body, and further including: four sets of pulley assemblies disposed inside the drone body, each of the four sets of pulley assemblies including a mounting frame and several sets of rollers; a battery body disposed on the top surface of the several sets of rollers, with a connector provided on one side of each of the two sets of battery bodies, and a snap-fit ​​rod fixedly connected to the bottom surface of each of the two sets of battery bodies; and limiting components disposed on the rear side of the two sets of connectors, each of the two limiting components including a mounting block, a rotating block, a limiting member, a pressing screw, and a pressing pad.

[0008] As a preferred technical solution of this utility model, the two sets of mounting blocks are arranged on the rear side of the two sets of connecting parts, and a rotating block is rotatably connected inside the two sets of mounting blocks. A limiting component is provided inside the two sets of mounting blocks, and a pressing screw is threaded inside the two sets of rotating blocks. A pressing pad is rotatably connected to one end of the two sets of pressing screws.

[0009] As a preferred technical solution of this utility model, the inside of the drone body is provided with two sets of sliding grooves, and the two sets of locking rods are slidably connected inside the sliding grooves.

[0010] As a preferred technical solution of this utility model, the top surface of the drone body is provided with a heat dissipation window, and both sides of the drone body are fixedly connected with fixing rods.

[0011] As a preferred embodiment of this utility model, one end of each of the two sets of fixing rods is fixedly connected to a support rod, and both ends of the two sets of support rods are fitted with protective pads.

[0012] As a preferred technical solution of this utility model, four sets of connecting rods are fixedly connected to the outside of the UAV body, and a propeller is fixedly connected to one end of each of the four sets of connecting rods.

[0014] Compared with the prior art, this utility model provides a tethered drone structure with replaceable batteries, which has the following advantages: 1. This tethered drone structure with replaceable battery, through the setting of the limiting component, connects the power cord interface to the wiring tube when the power cord is connected. The power cord is placed inside the mounting block. Rotating the rotating block closes the rotating block with the mounting block, and the limiting component limits it. At this time, rotating the extrusion screw pushes the extrusion pad to move. The extrusion pad moves and extrudes the power cord, so that the power cord is firmly clamped inside the mounting block and keeps it stably attached to the wiring tube interface. This effectively prevents the power cord from loosening or falling off due to drone flight vibration or external pulling.

[0015] 2. This tethered drone structure with replaceable battery, through the setting of pulley assembly and locking rod, allows the battery to be placed inside the drone body during use. The locking rod slides into the slide groove, and the battery is placed on the roller. The rolling characteristics of the roller can greatly reduce the frictional resistance between the battery and the inner wall of the drone body when pushing or pulling the battery in or out, making the battery installation operation more effortless and convenient. At the same time, it effectively avoids wear caused by friction between the battery and the inner wall, extending the service life of the battery and the drone body. Attached Figure Description

[0020] Specifically, all four mounting frames 201 are located inside the UAV body 1, and each of the four mounting frames 201 has several sets of rollers 202 inside.

[0021] In this embodiment, the mounting frame 201 is used to mount the roller 202. The roller 202 changes the friction between the battery and the inside of the drone body 1 from sliding friction to rolling friction, reducing the friction between the two and thus extending the service life of the battery body 3.

[0022] Specifically, two sets of mounting blocks 501 are located on the rear side of two sets of connectors 4. Rotating blocks 502 are rotatably connected inside both sets of mounting blocks 501. Limiting parts 503 are provided inside both sets of mounting blocks 501. Extrusion screws 504 are threadedly connected inside both sets of rotating blocks 502. Extrusion pads 505 are rotatably connected to one end of both sets of extrusion screws 504.

[0023] In this embodiment, during use, the mounting block 501 is used to place the power cord, the rotating block 502 initially limits the power cord, the limiting member 503 limits the rotating block 501 so that the rotating block 502 can close with the mounting block 502, and the extrusion screw 504 is used to drive the extrusion pad 505 to move, thereby extruding the power cord to prevent it from loosening or falling off due to external vibration or air resistance during use, thus ensuring the normal operation of the device.

[0024] Specifically, the drone body 1 has two sets of sliding grooves inside, and the two sets of locking rods 6 are slidably connected inside the sliding grooves.

[0025] In this embodiment, the slide is used to connect with the locking rod 6 to limit the battery body 3 and prevent the battery body 3 from falling off from the side.

[0026] Specifically, the top surface of the drone body 1 is provided with a heat dissipation window 7, and both sides of the drone body 1 are fixedly connected with fixing rods 8.

[0027] Specifically, one end of each of the two sets of fixing rods 8 is fixedly connected to a support rod 9, and both ends of the two sets of support rods 9 are fitted with protective pads 10.

[0028] In this embodiment, the fixed rod 8 and the support rod 9 are used to support the drone body 1 so that the drone body 1 can be placed on the ground, and the protective pad 10 is used to protect the drone body 1 and reduce the impact force generated when the drone body 1 lands.

[0029] Specifically, four sets of connecting rods 11 are fixedly connected to the outside of the drone body 1, and a propeller 12 is fixedly connected to one end of each of the four sets of connecting rods 11.

At this time, rotate the extrusion screw 504, the extrusion screw 504 rotates and pushes the extrusion pad 505 to move, the extrusion pad 505 moves and extrudes the power cord, so that the power cord is firmly clamped inside the mounting block 501 and keeps stable and close to the connector 15 interface, effectively preventing the power cord from loosening or falling off due to the vibration of the drone flight or external pulling. When in use, place the battery inside the drone body 1, and slide the locking rod 6 into the slide groove. At this time, the battery is placed on the roller 202. The rolling characteristics of the roller 202 can greatly reduce the frictional resistance between the battery and the inner wall of the drone body 1 when the battery is pushed in or pulled out, making the battery installation operation easier and more convenient. At the same time, it effectively avoids wear caused by friction between the battery and the inner wall, and extends the service life of the battery and the drone body 1.
