[0049] Combination Figures 1 to 6 As shown, a lightweight magnesium alloy UAV camera pod device includes a UAV body 1 and a pod assembly 2.

[0050] The pod assembly 2 is arranged at the lower part of the drone body 1, and the pod assembly 2 is made of magnesium alloy; the pod assembly 2 includes: a mounting seat 21, a rotating assembly 22, a positioning plate 23, a limiting rod 25 and a limiting member 26. The mounting seat 21 is detachably mounted on the lower part of the drone body 1 by means of screw connection; the rotating assembly 22 is arranged at the lower part of the mounting seat 21, and is used for the camera device to rotate 360 ​​degrees; the positioning plate 23 is arranged on the rotating assembly 22, and a positioning groove 24 is provided on the positioning plate 23; the limiting rod 25 is slidably sleeved on the positioning plate 23, and the limiting rod 25 passes through the positioning plate 23, and a limiting member 26 is threadedly sleeved.

[0051] Among them, by arranging a positioning plate 23 on the rotating component 22, the positioning plate 23 can play a positioning role for the installation of the camera device under the action of the positioning groove 24, and a limiting rod 25 is sleeved on the positioning plate 23, and a limiting member 26 is threadedly sleeved on the limiting rod 25. Under such a design, camera devices of different sizes can be fixedly installed on the positioning plate 23, so as to meet the changing market demands and specific requirements of the reconnaissance mission, and it is also convenient for the corresponding camera equipment to be installed and disassembled; by the combination of the mounting seat 21 and the rotating component 22, not only can the drone body 1 and the pod component 2 be detachably connected, but also the camera device can be rotated 360 degrees in all directions, adapting to various shooting angles and scene requirements, and enhancing the flexibility and diversity of shooting; by using magnesium alloy to manufacture the pod component 2, the overall weight of the drone can be further reduced under the action of magnesium alloy, a lightweight and high-strength material, so as to improve the carrying capacity of the drone.

[0052] Combination Figure 3 and Figure 4 As shown, convex parts 231 are fixedly provided on the upper and lower sides of the positioning plate 23, and the limiting rod 25 is in a U-shaped structure. Both ends of the limiting rod 25 pass through the convex parts 231 respectively, and the limiting member 26 is threadedly sleeved.

[0053] Among them, under such a design, the corresponding camera equipment can be detachably fixed in the positioning groove 24 of the positioning plate 23. At the same time, under the action of the positioning groove 24, the corresponding camera equipment is prevented from shaking. Under the action of the limiting member 26, camera equipment of different specifications and sizes can be installed to meet the needs of different places, which greatly improves the use range of the drone.

[0054] Combination Figure 4 and Figure 6 As shown, the limiting member 26 includes: a sleeve 261 and a driving block 262. The sleeve 261 is sleeved on the limiting rod 25; the driving block 262 is fixedly sleeved on the sleeve 261, and a plurality of anti-slip grooves 263 are formed on the driving block 262.

[0055] Among them, such a design is intended to provide a convenient and safe tightening and loosening mechanism. The sleeve 261 is threadedly matched with the limiting rod 25, so that the position of the sleeve on the limiting rod can be adjusted by rotating the driving block 262, thereby changing the degree of constraint of the limiting rod on the camera device, thereby fixing or releasing the camera device; the anti-skid groove 263 on the driving block 262 is a humanized design, and its main function is to increase the friction between the finger and the driving block during operation, prevent the hand from slipping during tightening or loosening, and improve the convenience and safety of operation.

[0056] Combination Figure 4 As shown, a spring 27 is sleeved on the limit rod 25, one end of the spring 27 abuts against the sleeve 261, and the other end abuts against the convex portion 231, so that under the action of the spring 27, when the camera device is installed, the spring 27 is in a compressed state, and it provides a certain elastic space between the sleeve 261 and the convex portion 231. In this way, even when the camera device is adjusted or subjected to external impact, the spring 27 can buffer the pressure applied by the limit rod 25 to the camera device, avoiding damage or deformation of the device due to over-tightening, thereby effectively protecting the safety of the camera device.

[0057] Combination Figure 2 As shown, the rotating assembly 22 includes: a panning rotating part 221, a first bending rod 222, a roll axis rotating part 223, a second bending rod 224 and a pitch axis rotating part 225. The panning rotating part 221 is arranged at the lower part of the mounting seat 21; the first bending rod 222 is arranged at the output end of the panning rotating part 221; the roll axis rotating part 223 is arranged at one side of the first bending rod 222; the second bending rod 224 is arranged at the output end of the roll axis rotating part 223; the pitch axis rotating part 225 is arranged at one side of the second bending rod 224, and the output end of the pitch axis rotating part 225 is connected to the positioning plate 23.

[0058] Among them, the heading rotation part 221 is arranged at the lower part of the mounting seat 21, which is responsible for the horizontal heading rotation of the camera device, allowing the device to rotate freely 360 degrees on the horizontal plane. The first bending rod 222 is connected to the output end of the heading rotation part 221, as a supporting structure, so that the rotation action can be transmitted from the heading rotation part to the subsequent roll axis rotation part 223. The roll axis rotation part 223 is arranged on one side of the first bending rod 222, which is responsible for the roll rotation of the camera device, that is, the device tilts left and right around an axis perpendicular to the ground. The second bending rod 224 is connected to the output end of the roll axis rotation part 223, which also plays the role of supporting and transmitting the rotation action. The pitch axis rotation part 225 is arranged on one side of the second bending rod 224, which is responsible for the pitch rotation of the camera device, that is, the device tilts up and down around an axis parallel to the ground. The positioning plate 23 is connected through the output end of the pitch axis rotation part 225, and is provided with a positioning groove 24 for installing and positioning the camera device. The rotation of the heading rotating part, the rolling axis rotating part and the pitch axis rotating part is controlled by a motor or other driving device. These rotating parts transmit the rotation action to the positioning plate through their respective output ends and bending rods, thereby driving the camera device to rotate in three-dimensional space. In this way, the drone can flexibly adjust the shooting angle of the camera device according to actual needs during flight to meet the needs of different viewing angles and shooting tasks.

[0059] Combination Figure 1 As shown, the drone body 1 includes: a body 11, an arm 12, a propeller 13 and a landing gear 14. A mounting seat 21 is provided at the lower part of the body 11; the arm 12 is provided around the body 11; the propeller 13 is provided on the arm 12; and the landing gear 14 is provided on both sides of the lower part of the body 11.

[0060] Among them, it should be noted that the arm 12, propeller 13 and landing gear 14 are all made of magnesium alloy, which is a lightweight metal material with a density lower than that of aluminum alloy, but with comparable strength. The use of magnesium alloy to make the arm, propeller and landing gear can significantly reduce the overall weight of the drone, improve its carrying capacity and flight efficiency, and reduce energy consumption during flight. Magnesium alloy has high strength and rigidity, and can withstand the stress and vibration generated during flight, ensuring the stability of the arm, the efficient operation of the propeller, and the cushioning capacity of the landing gear during landing. Magnesium alloy has good corrosion resistance, can resist erosion by environmental factors such as atmosphere and rain, and extend the service life of the drone.

[0061] Further references Figure 1As shown, the bottom end of the landing gear 14 is provided with a shock absorbing plate 15, the main function of which is to provide additional buffering and shock absorbing effects. When the UAV takes off and lands, especially when landing, the unevenness of the ground or the impact force may cause damage to the UAV body 1. The shock absorbing plate 15 can absorb and disperse these impact forces, protect the UAV body 11 and internal sensitive components from damage, ensure flight safety and equipment reliability, and the shock absorbing plate 15 can usually be made of the following materials:

[0062] 1. Rubber: Rubber shock-absorbing plates have good elasticity and can effectively absorb and disperse impact energy. At the same time, rubber has good weather resistance and wear resistance and is suitable for various environmental conditions.

[0063] 2. Foam plastics: such as polyurethane foam or EVA foam. These materials are lightweight and elastic, providing good cushioning without significantly increasing the weight of the drone.

[0064] 3. Spring materials: such as spring steel, which can provide rigid support and absorb some impact energy, but may be slightly heavier than rubber and foam plastics.

[0065] 4. Mixed materials: Shock-absorbing panels can also be a combination of multiple materials, such as rubber wrapped around a metal core, which combines the cushioning properties of rubber with the structural strength of metal.

[0066] The working mode of the utility model is as follows:

[0067] First, the two ends of the limit rod 25 are respectively inserted into the convex portion 231, so that the two ends of the limit rod 25 pass through the convex portion 231 respectively, and the corresponding spring 27 and sleeve 261 are sleeved on the two ends of the limit rod 25. Secondly, the corresponding camera device is placed in the positioning groove 24 on the positioning plate 23, so that the positioning groove 24 and the limit rod 25 can play a limiting role on the camera device under the action of the combination of the positioning groove 24 and the limit rod 25. Since the sleeve 261 is threadedly arranged on the limit rod 25, it is only necessary to rotate the drive block 262. At this time, the spring 27 is gradually compressed until the limit rod 25 completely fixes the camera device in the positioning groove 24 of the positioning plate 23, and the spring 27 can buffer the limit rod 25 from affecting the camera device. The pressure applied by the equipment can be avoided to avoid damage or deformation of the equipment due to over-tightening, thereby effectively protecting the safety of the camera equipment. If the camera equipment needs to be disassembled or replaced, the drive block 262 can be rotated in the opposite direction. After the camera equipment is fixedly mounted on the positioning plate 23, the rotation of the heading rotation part, the roll axis rotation part and the pitch axis rotation part can be controlled by a motor or other driving device. These rotation parts transmit the rotation action to the positioning plate through their respective output ends and bending rods, thereby driving the camera equipment to rotate in three-dimensional space. In this way, the drone can flexibly adjust the shooting angle of the camera equipment according to actual needs during the flight to meet the needs of different viewing angles and shooting tasks.

[0068] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
