[0037] See also Figure 1-8 In this embodiment: a device for automatically transmitting data of a tilt camera of a drone comprises a bracket 1, a drone body 2 is arranged above the bracket 1, a pan-tilt frame 3 is arranged below the drone body 2, a tilt camera body 4 is installed through the pan-tilt frame 3, a tilt camera body 4 is arranged inside the pan-tilt frame 3, and a mounting seat 8 is arranged above the pan-tilt frame 3;

[0038] The surface of the bracket 1 is provided with a mounting mechanism 5, the interior of the mounting mechanism 5 is provided with a data return mechanism 6, one side of the data return mechanism 6 is provided with a data transmission anti-drop mechanism 7, and the top of the mounting mechanism 5 is provided with a fixing mechanism 9;

[0039] The data transmission mechanism 6 includes a device body 61, a power line 62 and a data transmission line 63. The power line 62 is fixedly installed on one side of the upper surface of the device body 61, and the data transmission line 63 is fixedly installed on one side of the device body 61. The data collected by the tilt camera is transmitted back to the cloud through the data transmission mechanism 6.

[0040] The data transmission anti-slip mechanism 7 includes a socket 71, a slot 72, a card slot 73, a plug 74 and a reed 75. A slot 72 is provided on one side surface of the socket 71, the card slot 73 is located on both sides of the slot 72, and reeds 75 are fixedly installed on both side surfaces of the plug 74. The data transmission anti-slip mechanism 7 can prevent the data return mechanism 6 from loosening and falling off from the tilt camera, thereby ensuring the stability of data transmission.

[0041] See also Figure 1 and Figure 2 In this embodiment, the drone body 2 includes a frame 21, an arm 22, a motor 23 and a propeller 24. The arm 22 is fixedly mounted on one side surface of the frame 21, and the propeller 24 is movably connected to the upper output shaft of the motor 23.

[0042] In the above embodiment, the motor 23 can be connected to the frame 21 through the action of the support arm 22, and the propeller 24 can be driven to rotate under the action of the motor 23, so that the flight of the drone body 2 can be realized in cooperation with the frame 21.

[0043] Specifically, a tilt camera body 4 is installed below the drone body 2 through a gimbal frame 3. The tilt camera body 4 can collect flight data of the drone body 2. At the same time, a bracket 1 is installed below the drone body 2, and a mounting mechanism 5 is installed on the surface of the bracket 1. Therefore, the data automatic return effect is achieved through the data return mechanism 6 inside the mounting mechanism 5 in conjunction with the tilt camera body 4. The specific structure and function of the mounting mechanism 5 are described and introduced in detail below.

[0044] See also Figure 2 , Figure 4 and Figure 5 In this embodiment, the mounting mechanism 5 includes a mounting frame 51, a shell 52, an arc-shaped groove 53 and a socket 54. The shell 52 is fixedly installed inside one side of the mounting frame 51, the arc-shaped groove 53 is opened at one end of the mounting frame 51, and the socket 54 is movably installed with the mounting frame 51.

[0045] In the above embodiment, the data return mechanism 6 can be installed and fixed under the action of the shell 52, and the installation mechanism 5 can be connected to the bracket 1 under the action of the installation frame 51 installed on both sides of the shell 52. At the same time, the arc grooves 53 opened at the four corners of the installation frame 51 can cooperate with the card seat 54 to install and fix the installation mechanism 5 as a whole.

[0046] Furthermore, the mounting frame 51 is composed of two groups of fixing plates and four groups of clamping joints. The mounting frame 51 and the clamping seat 54 are movably mounted by bolts, and the mounting mechanism 5 and the bracket 1 are movably mounted.

[0047] Since the bracket 1 is provided with two groups, and the mounting frame 51 is composed of two groups of fixing plates and four groups of clamping joints, the mounting frame 51 can be connected to the bracket 1 through the action of the clamping joints and the fixing plates. At the same time, the mounting frame 51 is installed and fixed to the bracket 1 of the drone body 2 under the action of the arc groove 53 opened in the clamping seat 54 and the clamping joint with the bolts.

[0048] Among them, the shell 52 of the installation mechanism 5 is used to install the data return mechanism 6, and the data return mechanism 6 is snap-connected with the shell 52, so the fixation of the data return mechanism 6 requires another fixing structure. Therefore, the specific structure and function of the fixing mechanism 9 acting on the data return mechanism 6 are described and introduced in detail below.

[0049] See also Figure 4 , Figure 6 and Figure 7 In this embodiment, the fixing mechanism 9 includes a pressure strip 91, a fixing bolt 92, a rubber pad 93 and a shock-absorbing pad 94. The fixing bolt 92 is sleeved inside one side of the pressure strip 91, the pressure strip 91 is fixedly installed below the rubber pad 93, and the shock-absorbing pad 94 is fixedly installed inside the mounting mechanism 5.

[0050] In the above embodiment, the pressure strip 91 can be connected to the shell 52 by the action of the fixing bolt 92, and the fixing bolt 92 is threadedly connected to the shell 52, so when the fixing bolt 92 is rotated, the pressure strip 91 can drive the rubber pad 93 to move downward to clamp and fix the data return mechanism 6 inside the shell 52, and the data return mechanism 6 has a certain buffering effect through the action of the shock-absorbing pad 94 and the rubber pad 93, thereby avoiding damage.

[0051] Furthermore, the device body 61 is snapped into the interior of the mounting mechanism 5 , one end of the power cord 62 is fixedly mounted on the device body 61 , and the other end is movably connected to the drone body 2 via a USB interface, and the data transmission line 63 is fixedly mounted on the data transmission anti-detachment mechanism 7 .

[0052] Through the USB interface at the other end of the power cord 62 installed above the device body 61, the data return mechanism 6 can draw power from the drone body 2. At the same time, a data transmission anti-detachment mechanism 7 is installed between the data transmission line 63 and the tilting camera body 4, which can make the connection between the data transmission line 63 and the tilting camera body 4 more stable.

[0053] Specifically, the data transmission line 63 is fixedly connected to the plug 74, the plug 74 is movably connected to the slot 72 of the socket 71, the socket 71 is fixedly installed with pins inside and is fixedly installed with the tilting camera body 4, the reed 75 is engaged with the card slot 73, and the data return mechanism 6 and the data transmission anti-detachment mechanism 7 constitute a data transmission component and a data return device.

[0054] By cooperating with the socket 71 installed on the back of the tilting camera body 4, the plug 74 can transmit the data collected by the tilting camera body 4 during flight to the data transmission line 63, and then to the device body 61, and the reeds 75 installed on both sides of the plug 74 can cooperate with the slots 73 opened on both sides of the surface of the socket 71. The reaction force of the reed 75 makes the reed 75 stuck in the inside of the slot 73, thereby avoiding the problem of looseness of the plug 74 and the socket 71 causing data transmission failure.

[0055] See also Figure 4 ,and Figure 8 In this embodiment, the device body 61 of the data return mechanism 6 includes a data integration module, a data encryption module, a data compression module, a data integration output module and a data transmission module. The data encryption module can encrypt the data transmitted by the tilt camera body 4 and compress and output it under the action of the data compression module.

[0056] In the above embodiment, the data collected by the tilt camera body 4 can be encrypted by the data encryption module and compressed and output by the data compression module, so that the amount of data collected by the tilt camera body 4 can be increased, and the privacy of the collected data can also be protected.

[0057] It is worth noting that an error recognition module is installed at one end of the data transmission module. Therefore, when the drone body 2 flies to an area where the signal is unstable, data return failure may occur. The error recognition module can identify the return failure, thereby sending a signal to the data retransmission module, which in turn starts the data transmission module to achieve the retransmission effect, thereby ensuring the stability of data return.

[0058] The loading and unloading process of the automatic data return device of the present invention is as follows: after the operator places the data return mechanism 6 inside the shell 52, and places the pressure strip 91 above the data return mechanism 6, the pressure strip 91 is connected to the shell 52 by using the fixing bolts 92, and the installation and fixation of the data return mechanism 6 is completed. At the same time, after the mounting frame 51 is clamped between the brackets 1, the mounting frame 51 and the bracket 1 are installed and fixed by using the clamping seat 54 and the bolts, the plug 74 is held and the spring 75 is pressed inwardly, and the plug 74 is sent into the slot 72, and the spring 75 is sent into the slot 73. The reaction force of the spring 75 makes the connection between the plug 74 and the socket 71 more stable, and the USB connector of the power cord 62 above the processing device body 61 is connected to the power output USB interface of the drone body 2, and the data automatic return device can be powered.

[0059] The specific use process of the automatic data return device of the present invention is as follows: the data collected by the tilt camera is transmitted to the data return device through the data transmission component composed of the data transmission anti-detachment mechanism 7 and the data transmission line 63. Under the action of the automatic control script, the data integration module integrates the collected data, and then encrypts it through the data encryption module and sends it to the data compression module for compression and integration and sends it to the data transmission module. The data is returned to the cloud storage module through the data transmission module, and the wireless transmission module can send the data wirelessly to the ground receiving platform. When the drone is in an unstable signal area and the data return fails, it can be identified and judged by the error recognition module, thereby starting the data retransmission module and the data transmission module to achieve the retransmission effect, thereby ensuring the stability of the automatic return of the tilt camera data.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
