Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle accessories, in particular to a waterproof structure of a unmanned aerial vehicle body. Background Art

[0002] In recent years, drone technology has garnered widespread attention and interest worldwide. It has demonstrated immense value in military applications such as battlefield surveillance and early warning, while also opening up a wide range of civilian applications. Equipped with high-resolution visible light or infrared cameras, drones can easily reach inaccessible areas for aerial reconnaissance and photography, significantly facilitating tasks such as terrain mapping and disaster monitoring.

[0003] Drones often encounter rainy weather during their missions. Currently, many drones typically suspend operations in rainy conditions until the weather improves. However, sometimes, a drone encounters sudden rainfall during flight. Ideally, the drone would return home immediately. However, this process takes time, during which rainwater could drip onto the drone's roof and potentially penetrate its interior, posing a potential threat to its normal operation.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5As shown, a waterproof structure of a drone fuselage includes a drone body 1, a top plate 2 is fixed to the surface of the drone body 1, an electric push rod 3 is fixed to the inner cavity of the drone body 1, a connecting rod 4 is fixed to the active end of the electric push rod 3, a motor 5 is fixed to the inner cavity of the connecting rod 4, a rotating column 6 is fixed to the output shaft of the motor 5, and both sides of the surface of the rotating column 6 are provided with extending mechanisms 7 for absorbing water. When the utility model is in use, if there is a sudden rainy day, the staff can use the electric push rod 3. Under the action of the electric push rod 3, the extending mechanisms 7 on both sides are extended, and then under the action of the motor 5, the rainwater on the top of the drone body 1 can be temporarily absorbed by the extending mechanism 7, thereby assisting the drone body 1 to return and avoiding rainwater from being retained on the surface of the drone body 1.

[0021] A hiding groove 11 is provided on the surface of the top plate 2, and the extending mechanisms 7 on both sides are arranged on the surface of the hiding groove 11. In this embodiment, the setting of the hiding groove 11 provides hiding points for the extending mechanisms 7 on both sides, thereby preventing the extending mechanisms 7 on both sides from protruding when not in use and affecting the normal flight of the drone body 1.

[0022] The extending mechanism 7 includes a connecting block 71 fixed on both sides of the surface of the rotating column 6, and an extension plate 72 is slidably provided in the inner cavity of the connecting block 71. A spring 73 is fixed on one side of the surface of the extension plate 72, and the other end of the spring 73 is fixed to the surface of the connecting block 71. The surfaces of the connecting block 71 and the extension plate 72 are both provided with a water-absorbing material. In this embodiment, through the arrangement of the connecting block 71, the extension plate 72 and the spring 73, under the action of the connecting block 71, space is provided for the hiding of the extension plate 72. If the extension plate 72 is separated from the top plate 2 and the hiding groove 11, the extension plate 72 is extended under the action of the spring 73.

[0023] Limit blocks 8 are fixed on both sides of the surface of the extension plate 72, and limiting columns 9 are slidingly set in the inner cavity of the extension plate 72. In this embodiment, the setting of the limit blocks 8 and the limit columns 9 provides limits for the movement of the extension plate 72, thereby improving the stability of the extension plate 72 during operation and movement.

[0024] The center of gravity of the connecting blocks 71 and the extension plates 72 on both sides coincides with the axis of the rotating column 6. In this embodiment, this arrangement improves the stability of the rotating column 6, the connecting blocks 71 and the extension plates 72 when the motor 5 drives them to rotate, thereby improving the practicality of the device.

[0025] Several brush points 10 are fixed on the surface of the extension plate 72, and the brush points 10 are also arranged on the surface of the connecting block 71. In this embodiment, by setting the brush points 10, the working range of the connecting block 71 and the extension plate 72 is improved, and the absorption ability of the connecting block 71 and the extension plate 72 to the concave part on the top of the drone body 1 can be improved.

[0026] Working principle: During the daily operation of the drone body 1, if it rains lightly and the drone body 1 cannot return immediately, the staff can use the remote control device to make the electric push rod 3 work, and then, under the drive of the electric push rod 3, the connecting rod 4 and the rotating column 6 are extended upward, so that the connecting block 71 drives the extension plate 72 to the working range. After the extension plate 72 is free from the restriction of the top plate 2, the extension plate 72 can be popped out under the action of the spring 73, thereby increasing the working range of the connecting block 71 and the extension plate 72. Then, under the action of the motor 5, the rotating column 6 can drive the connecting block 71 and the extension plate 72 to rotate, so that during the rotation of the connecting block 71 and the extension plate 72, the connecting block 71 and the extension plate 72 absorb the water droplets on the top of the drone body 1 to prevent excessive water from being retained and seeping into the drone body 1, thereby affecting the normal operation of the drone body 1. With the cooperation of the extending mechanism 7, the drone body 1 can temporarily deal with the water droplets on the surface of the drone body 1. At this time, due to the rain, the drone body 1 should return as soon as possible and be maintained.
