[0067] The adjusting screw 221 is used to drive the connecting gear 21 to rotate.

[0068] like Figure 3 It can be seen that the adjusting screw 221 is fixed close to the rotating gear 21 to facilitate the rotation of the connecting gear 21.

[0069] In one embodiment, Figure 4 is a schematic diagram of a top cross-sectional structure of a telescopic mechanism provided according to Embodiment 3 of the present invention, such as Figure 4 As shown, the telescopic mechanism 23 includes: a limiting groove 231, an upper and lower plate control column 232, a radial movable block 233, an upper ring 234 and a lower ring 235.

[0070] The limiting groove 231 is a groove having a preset angle with the radial line;

[0071] The upper circular ring 234 surrounds and is sleeved on the outer circumference of the connecting gear 21, and is fixed to the connecting gear 21; the limiting groove 231 is set on the lower surface of the upper circular ring 234; the lower circular ring 235 is coaxially set with the upper circular ring 234, and is fixed based on the upper and lower plate control columns 232; the radial movable block 233 is movably embedded and installed in the lower circular ring 235, and the upper and lower plate control columns 232 are installed on the top of the radial movable block 233 and are movably fixed in the limiting groove 231, so that the radial movable block 233 can perform radial telescopic movement with the center of the circle of the lower circular ring 235 as the center.

[0072] The limit groove 231 is a groove with a preset angle with the radial line. The preset angle can be an angle set according to user needs. In actual operation, the preset angle is greater than 0 degrees. The length of the limit groove 231 can be set according to the required telescopic length of the telescopic mechanism 23. The number of the limit grooves 231 can be at least 2. Figure 4 Taking six limiting grooves 231 as an example, the number of limiting grooves 231, upper and lower disk control columns 232 and radial movable blocks 233 are the same. The upper and lower disk control columns 232 can be used to fix the upper ring 234 and the lower ring 235, and the upper and lower disk control columns 232 can move in the limiting grooves 231. The radial movable block 233 refers to a module that can move in a radial line, and the radial movable block 233 can be movably embedded and installed in the lower ring 235. The upper ring 234 and the lower ring 235 can be coaxial rings with the same outer circumference.

[0073] In actual operation, the position of the upper and lower plate control posts 232 is limited by the limit grooves 231, so that the radial movable block 233 connected thereto can perform radial telescopic movement with the center of the lower disk ring 235 as the center, which is convenient for adjusting the telescopic diameter. In one embodiment, when the number of the limit grooves 231, the upper and lower plate control posts 232 and the radial movable block 233 is the same, that is, 6, the mounting device 20 can be called a 6-star structure.

[0074] In one embodiment, Figure 5 is a schematic diagram of a front cross-sectional structure of a buckle mechanism provided according to Embodiment 3 of the present invention, such as Figure 5 As shown, the buckle mechanism 24 includes a buckle support column 241 and a buckle 242 .

[0075] The buckle support column 241 is fixed to the bottom of the radial movable block 233 of the telescopic mechanism 23 ; the buckle 242 is horizontally installed inside the buckle support column 241 based on the spring.

[0076] The buckle support column 241 is used to fix the buckle 242. The buckle support column 241 can be cylindrical, cubic or Figure 5 The T-shaped three-dimensional structure shown, the buckle 242 can be used to fix the device to be mounted.

[0077] In the embodiment, since the buckle support column 241 is fixed to the radial movable block 233 of the telescopic mechanism 23, the number of the buckle mechanisms 24 should be consistent with the number of the radial movable blocks 233. At this time, multiple buckles 242 can clamp the device to be mounted to facilitate the mounting of the device to be mounted and prevent the device to be mounted from falling.

[0078] In one embodiment, Figure 6 is a schematic diagram of a main cross-sectional structure of a mounting device provided according to Embodiment 3 of the present invention, such as Figure 6 As shown, the screw mechanism 22 is installed on the tooth surface of the connecting gear 21, the telescopic mechanism 23 is installed on the tooth surface of the connecting gear 21, and the buckle mechanism 24 is installed at the bottom of the telescopic mechanism 23, which is used to fix the equipment to be mounted on the drone. Among them, the upper ring 234 surrounds and is sleeved on the outer circumference of the connecting gear 21, and is fixed to the connecting gear 21; the limiting groove 231 is set on the lower surface of the upper ring 234, the lower ring 235 is coaxially set with the upper ring 234, and is fixed based on the upper and lower plate control columns 232, the radial movable block 233 is movably embedded and installed in the lower ring 235, and the upper and lower plate control columns 232 are installed on the top of the radial movable block 233, and are movably fixed to the limiting groove 231. Its working principle is to rotate the adjusting screw 221 to drive the connecting gear 21 to rotate, thereby driving the upper disk 234 of the telescopic mechanism 23 to rotate. Since the limiting groove 231 limits the position of the upper and lower disk control columns 232, the radial movable block 233 connected thereto can perform radial telescopic movement with the center of the lower disk 235 as the center, thereby changing the diameter of the clamped object controlled by the buckle mechanism 24, realizing adaptive adjustment of the caliber size of the buckle mechanism 24, and facilitating the mounting of equipment of multiple sizes to be mounted.

In this embodiment, two transverse support rods and two longitudinal support rods are welded to form a support frame 11, two movable fixing bars 12 are fixed obliquely to the longitudinal support rod position of the support frame 11, and two movable fixing buckles 13 are respectively installed on each movable fixing bar 12, which can be directly moved freely on the movable fixing bar 12, the voltage conversion module 40 and the power supply module 30 are installed at the midpoint of the upper transverse support rod, the crash protection device 60 and the positioning device 50 are installed at the midpoint of the lower transverse support rod, and the four mounting devices 20 are respectively installed at the intersection of the transverse support rod and the longitudinal support rod in the support frame 11.

[0104] In one embodiment, Fig.13 is a schematic diagram of the structure of a crash protection device provided according to Embodiment 7 of the present invention. Fig.13 As shown, the crash protection device includes: an ejection trigger 61, a carbon dioxide airbag 62, a parachute 63 and a controller 64. The carbon dioxide airbag 63 is connected to the ejection trigger device 61 and the parachute respectively, and the controller 64 is connected to the ejection trigger 61.

[0105] The controller 64 is used to detect the flight state of the UAV safety mounting platform, and generate a trigger signal when the flight state meets the preset flight state;

[0106] When the ejection trigger 61 receives a trigger signal, the ejection trigger 61 triggers the carbon dioxide airbag 62 to start ejection, and the parachute 63 is ejected.

[0107] In one embodiment, the preset flight state includes the drone safety mounting platform being in a falling state.

[0108] In an embodiment, the controller 64 can monitor the flight status of the drone safety mounting platform in real time. When it is determined that the flight status of the drone safety mounting platform is a falling state, a trigger signal can be transmitted to the ejection trigger 61. When the ejection trigger 61 receives the trigger signal, the ejection trigger 61 triggers the carbon dioxide airbag 62 to start the ejection, and the parachute 63 is ejected to protect the safe descent of the drone safety mounting platform.

[0109] In one embodiment, Fig.14FIG. 1 is a flow chart of a trigger signal determination method provided according to Embodiment 7 of the present invention. Fig.14 As shown, the trigger signal is determined as follows:

[0110] The initial optical flow feature points can be determined first. Usually, the corner detection algorithm can be used to extract significant feature points from the image taken by the drone, such as the corners of the building and specific signs on the ground as the initial optical flow feature points. The motion vector of the corresponding feature point in the next frame of the image is calculated by using the pyramid optical flow method. Taking the pyramid optical flow method as an example, the image is first continuously downsampled to construct an image pyramid, and then the optical flow is calculated on image layers of different resolutions, starting from the top layer and gradually refining downwards, which can improve the accuracy and robustness of the optical flow calculation. The displacement of each feature point between adjacent frames is calculated, that is, the horizontal and vertical motion vectors. The mean motion vector is generated by averaging the motion vectors of all feature points. When it is determined that the difference between adjacent vectors exceeds the threshold, the fall probability variable value is determined to be increased; if the anomaly exceeds the threshold for three consecutive times, the fall variable value is cleared to determine whether the fall probability reaches the threshold. If not, the optical flow feature points are continued to be extracted to calculate the optical flow; if so, a fall protection trigger signal is issued. There is no need to add complex and expensive sensors, which reduces the cost and system complexity.

[0111] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0112] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
