[0009] Preferably, the mounting end of the carbon fiber plate is installed corresponding to the outer ring of the gear set housing, and the carbon fiber plate is provided with mounting holes.

[0010] Preferably, a limit switch is provided on the gear set housing, the limit switch is electrically connected to the drive motor, and both the drive motor and the limit switch are electrically connected to the control panel of the flight vehicle.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This utility model has a simple overall structure. The gear set housing made of aluminum alloy greatly reduces the weight of the overall device while meeting the tensile requirements, reducing the impact on the overall mass when fixed to the unmanned aerial vehicle, thus ensuring the stability of the unmanned aerial vehicle. At the same time, the gear set is in a closed state, effectively preventing grease leakage and sand and dust intrusion. The setting of limit switches can trigger the power-off mechanism when the winding length of the high-horsepower fiber rope reaches the set maximum or minimum point, ensuring that the hook will not damage the frame and improving safety.

[0018] Example

[0019] As shown in Figures 1-3, this utility model proposes a lightweight electric winch, including a gear set housing 1. The gear set housing 1 is composed of two aluminum alloy parts. The aluminum alloy gear set housing 1 significantly reduces the overall weight of the electric winch while ensuring its safety and stability during operation. A drive motor 2 is installed on one side of the gear set housing 1, with its mounting end corresponding to one side of the gear set housing 1. The mounting end of the drive motor 2 is fixedly connected to one side of the gear set housing 1. The power of the drive motor 2 can support the electric winch to retract all the high-power fiber rope 4 within one minute when fully loaded, ensuring efficiency and controlling the hovering time of the unmanned aerial vehicle. The gear set housing 1 is equipped with... A limit switch is provided, electrically connected to the drive motor 2. One end of the limit switch is fixedly connected to a pawl rotatably mounted inside the gear set housing 1. The pawl can position and close the gear set. Both the drive motor 2 and the limit switch are electrically connected to the control panel of the aircraft. The device can be electrically controlled through the control panel. The limit switch setting can be controlled by the drive motor 2. During hoisting operations, when the winding length of the high-power fiber rope 4 reaches the set highest or lowest point, the built-in pawl will be triggered to achieve the power-off mechanism, ensuring that the hook will not damage the frame and improving safety. A gear set 6 is provided inside the gear set housing 1, which consists of five reduction gears. The gear set is assembled from two gears. One side of the gear set housing 1 has a shaft hole. The output end of the drive motor 2 passes through the shaft hole and is installed correspondingly to the inner ring of a set of gears within the gear set 6. The output end of the drive motor 2 is fixedly connected to the inner ring of the set of gears within the gear set 6. The entire gear set 6 is enclosed within the gear set housing 1, effectively preventing grease leakage and dust intrusion during flight. The gear set 6 allows for adjustment and control of the speed of the drive motor 2. A connecting flange 7 is located on one side of the gear set 6. An assembly groove is located on the gear set housing 1 near the drive motor 2. The mounting end of the connecting flange 7 passes through the assembly groove and is installed correspondingly to one side of the gear set 6. The mounting end of the connecting flange 7 is fixedly connected to one side of another set of reduction gears within the gear set 6. A cable hub 3 is provided on one side of the wheel assembly housing 1. The other end of the connecting flange 7 is installed correspondingly to one side of the cable hub 3. The mounting end of the cable hub 3 is fixedly connected to one end of the connecting flange 7. The connection flange 7 allows the drive motor 2 to drive the cable hub 3 to rotate via the gear set 6 during operation. A high-power fiber rope 4 is wound around the outer ring of the cable hub 3. One end of the high-power fiber rope 4 is installed correspondingly to the groove of the cable hub 3 and is fixedly connected to the cable hub 3. A hook is fixedly provided at the other end of the high-power fiber rope 4. When the cable hub 3 is rotating, the high-power fiber rope 4 can be wound up and down, thereby meeting the lifting requirements of the UAV flying vehicle. A carbon fiber plate 5 is provided on the upper side of the outer ring of the gear set housing 1.The mounting end of carbon fiber plate 5 is installed correspondingly to the outer ring of gear set housing 1. The mounting end of carbon fiber plate 5 is fixedly connected to gear set housing 1. The carbon fiber plate 5 further reduces the weight of the electric winch. Mounting holes are provided on carbon fiber plate 5, and the positions of these holes correspond to the mounting holes of the unmanned aerial vehicle. The mounting holes on carbon fiber plate 5 allow for the fixed assembly of the electric winch with the aerial vehicle.

[0020] In this embodiment, when an unmanned aerial vehicle (UAV) is needed for lifting operations, the operator first aligns the mounting holes on the carbon fiber plate 5 with the mounting holes on the UAV, then secures the device to the UAV using bolts. The operator then powers on the UAV, suspending it in flight. The operator then presets the length of the high-powered fiber rope 4 using the UAV's control panel, and then powers on the drive motor 2. The drive motor 2 rotates the connecting flange 7 via the gear set 6, and the rotation of the connecting flange 7 adjusts the length of the high-powered fiber rope 4 via the pulley hub 3. Finally, the operator uses the hook at one end of the high-powered fiber rope 4 to lift the desired item. Once the length of the high-powered fiber rope 4 has been adjusted to the predetermined length, a limit switch sends a power-off command to the drive motor 2, preventing the hook from damaging the frame. The above specific embodiment is merely a preferred embodiment of this utility model. Based on the technical solution of this utility model and the related teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
