[0034] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further describes the exemplary embodiments of the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] Please refer to Figures 1-4 , Figure 1 which is an axonometric schematic diagram of a connection device for a pan-tilt provided by an embodiment of the present application; Figure 2 is Figure 1 a top view structural schematic diagram of Figure 3 is Figure 1 a front view structural schematic diagram of Figure 4 which is an installation schematic diagram of a pan-tilt and a connection device provided by an embodiment of the present application; Figure 5 which is an installation structure schematic diagram of a pan-tilt mounting system provided by an embodiment of the present application; Figure 6 which is an assembly structure schematic diagram of a pan-tilt and a connection device provided by an embodiment of the present application.

[0036] In a specific embodiment, the connection device for a pan-tilt provided by the present application includes a connecting plate 1 and a fixing bracket 11. Among them, the connecting plate 1 is preferably a rectangular plate structure. The connecting plate 1 is located below the pan-axis motor 22 of the pan-tilt, so that the microwave signal transmission device 3 can be arranged directly below the pan-axis motor 22 of the pan-tilt, ensuring that the microwave signal transmission device 3 does not affect the center-of-gravity balance of the pan-tilt. The connecting plate 1 is used to provide an installation position for the microwave signal transmission device 3. Preferably, the microwave signal transmission device 3 is arranged on the lower surface of the connecting plate 1, that is, on the side away from the pan-axis motor 22. Specifically, a fixing bracket 11 is arranged on the connecting plate 1, and the fixing of the connecting plate 1 to the pan-axis assembly 2 is achieved through the fixing bracket 11. It can be understood that the pan-axis assembly 2 includes a pan-axis motor 22 and a pan-axis cross bar 21. The specific structures and connection relationships of the two refer to the prior art and will not be elaborated here. The fixing bracket 11 is fixed to the upper surface of the connecting plate 1. The up and down directions mentioned here and below are set based on the vertical direction. The fixing bracket 11 is perpendicular to the upper surface of the connecting plate 1. The fixing bracket 11 specifically includes a first fixing vertical beam 111, a second fixing vertical beam 112, and a fixing cross beam 113. The first fixing vertical beam 111 and the second fixing vertical beam 112 are arranged in the same structure and are arranged along the width direction of the connecting plate 1. The fixing cross beam 113 is arranged between the first fixing vertical beam 111 and the second fixing vertical beam 112. The two ends of the fixing cross beam 113 are preferably welded or integrally formed with the first fixing vertical beam 111 and the second fixing vertical beam 112 for easy production and processing. It can be seen that the first fixing vertical beam 111, the second fixing vertical beam 112, and the fixing cross beam 113 form a portal frame structure. The middle of the portal frame structure is convenient for the pan-axis cross bar 21 to pass through, so as to be hoisted on the pan-axis cross bar 21 of the pan-tilt through the fixing cross beam 113, increasing the contact area and providing stability, and at the same time providing an installation position for subsequent fixing. Preferably, threaded holes can be arranged on the fixing cross beam 113, and the fixing of the connection device for the pan-tilt and the microwave signal transmission device 3 is achieved by setting threaded fasteners.

[0037] By using a connection device for a pan-tilt, a pan-tilt, and an aerial photography unmanned aerial vehicle provided in the embodiment of the present application, compared with the prior art, the following technical effects are achieved:

[0038] The connecting plate 1 is arranged below the pan-axis motor 22 of the pan-tilt to achieve a fixed connection with the pan-tilt. The microwave signal transmission device 3 is installed on the connecting plate 1, and the fixing bracket 11 is hoisted on the pan-axis cross bar 21 of the pan-tilt through the fixing cross beam 113, so that the microwave signal transmission device 3 can be arranged below the pan-axis motor 22, reducing the influence of the microwave signal transmission device 3 on the center-of-gravity balance of the pan-tilt and ensuring flight safety. The above connection device realizes the connection and fixation of the microwave signal transmission device 3 and the pan-tilt, thereby enabling the pan-tilt to carry the microwave signal transmission device 3, completing the reasonable loading of the unmanned aerial vehicle flight system, adjusting the on-board balance, and realizing the technical relay requirements of the 4K ultra-high-definition broadcast standard.

[0039] Specifically, when the fixed crossbeam 113 is hoisted on the heading axis crossbar 21, in order to enable the fixed crossbeam 113 to be close to the side of the heading axis motor 22, an arc-shaped recess 1131 is provided on the side wall of the fixed crossbeam 113 close to the heading axis motor 22. Through the arc-shaped recess 1131, it can fully fit the arc-shaped side wall of the heading axis motor 22, so as to optimize the space utilization rate and improve the stability of the device at the same time.

[0040] Furthermore, first mounting holes 114 are respectively provided on the upper surfaces of the first fixed vertical beam 111 and the second fixed vertical beam 112. The connecting plate 1 can be fixed to the heading axis crossbar 21 through the first mounting holes 114 and threaded fasteners. The threaded fasteners are screws. Preferably, two first mounting holes 114 are provided on the first fixed vertical beam 111 and the second fixed vertical beam 112 respectively, and every two first mounting holes 114 are arranged on the first fixed vertical beam 111 / second fixed vertical beam 112 along the length direction of the connecting plate 1.

[0041] In one embodiment, in order to further improve the stability of the connecting device, a cushion block 12 is further included. The cushion block 12 is preferably set as a rectangular plate structure. The cushion block 12 has a hollow cavity, and the hollow cavity penetrates through the cushion block 12 along the length direction of the connecting plate 1; the cushion block 12 is provided with second mounting holes 121, and the second mounting holes 121 penetrate through the wall thickness direction of the cushion block 12 to the inside of the hollow cavity; the second mounting holes 121 are used to cooperate with the threaded fasteners to fix the cushion block 12 and the heading axis crossbar 21. The cushion block 12 is fixed to the upper surface of the connecting plate 1. The cushion block 12 and the fixing frame 11 are respectively located at both ends of the length direction of the connecting plate 1. The cushion block 12 is used to contact the lower surface of the heading axis crossbar 21 and is detachably and fixedly connected. The cushion block 12 and the connecting plate 1 are preferably integrally provided for easy production and processing; in the length direction of the connecting plate 1, the cushion block 12 and the fixing frame 11 are respectively located at both ends. Second mounting holes 121 are provided on the upper surface of the cushion block 12 and are fixed to the heading axis crossbar 21 through threaded fasteners to further improve the stability of the device. Similarly, the number of the second mounting holes 121 is four, and every two second mounting holes 121 are respectively located at both ends of the length direction of the cushion block 12, and the two second mounting holes 121 on the same side of the cushion block 12 are arranged along the length direction of the connecting plate 1.

[0042] Among them, a plurality of third mounting holes 13 are provided on the connecting plate 1, and the third mounting holes 13 are used to mount the microwave signal transmission device 3; specifically, they can be matched with threaded fasteners. In this embodiment, the third mounting holes 13 are strip-shaped holes, and the strip-shaped holes are arranged along the length direction of the connecting plate 1. The connecting device for the gimbal further includes an adjusting bolt, and the adjusting bolt can move along the length direction of the strip-shaped hole on the connecting plate 1 so as to be adjusted in time when there is an installation error to ensure the smooth progress of the installation; and the microwave signal transmission device 3 is located directly below the yaw axis motor 22 to reduce the influence on the center of gravity balance of the gimbal. It can be understood that the adjusting bolt is used to fix the microwave signal transmission device 3 to the connecting plate 1; the outer diameter of the adjusting bolt is smaller than the inner diameter of the strip-shaped hole so that the adjusting bolt can slide in the strip-shaped hole.

[0043] Specifically, the above-mentioned threaded fasteners and mounting holes adopt hidden multi-point fixation, which is safe, firm, beautiful, simple, and convenient for disassembly and replacement. The above-mentioned connecting device is made of nylon PA12 material, which is strong and durable.

[0044] At the same time, in order to achieve the reasonable loading of the UAV flight system and adjust the on-board balance, a plurality of weight reduction holes 14 are respectively provided on the connecting plate 1 and the cushion block 12 for weight reduction.

[0045] By combining the above device with the electronic stabilization system carried by the UAV flight system for the microwave signal transmission system, the following technical advantages can be achieved: by using this device, the microwave transmission system can be installed on the DJI Ronin-MX electronic stabilization system, ensuring that the picture signal transmitted by the UAV aerial photography meets the 4K ultra-high definition broadcast standard; it is convenient for disassembly, replacement, and upgrade; the flight safety is guaranteed through flight balance debugging; a technical breakthrough in the 4K ultra-high definition live wireless transmission technology of the UAV is achieved.
