Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV aerial photography gimbal. Background Technology

[0002] A drone is an aircraft that does not require a pilot to operate and is controlled by a remote control device or autonomous program. The aerial photography gimbal is one of the main structures of a drone. It is a core component used to carry aerial photography equipment (such as cameras, video cameras, etc.) and to achieve stable control of them. In actual use, it has the advantages of structural stability, long service life and precise adjustment.

[0003] Existing drone aerial photography gimbals require a shock-absorbing structure to connect to the mounting plate. The shock-absorbing structure is often connected to the drone and the mounting plate using bolts. The disassembly and assembly of multiple bolts is cumbersome and time-consuming, making it inconvenient for workers to inspect and replace the shock-absorbing structure. At the same time, the mounting plate needs to be connected to the drone with bolts. If the bolts are stored separately from the mounting plate, they are prone to being lost, which in turn affects the installation of existing drone aerial photography gimbals.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drone aerial photography gimbal that has the advantages of easy disassembly and assembly of the shock-absorbing structure and avoidance of bolt loss, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of easy disassembly and assembly of the shock-absorbing structure and to avoid the loss of bolts, the specific technical solution adopted by this utility model is as follows: A drone aerial photography gimbal includes a frame and a mounting plate. Two sets of mounting boxes are arranged between the frame and the mounting plate. A first self-locking forward and reverse motor is fixedly mounted on the inner bottom surface of the frame, and a concave frame is fixedly mounted on the output end of the first self-locking forward and reverse motor. A mounting shaft is mounted inside the concave frame via bearings. A camera is fixedly sleeved on the side wall of the mounting shaft. A second self-locking forward and reverse motor is mounted on the side wall of the concave frame. The upper part of the mounting plate has multiple sets of connecting holes, and mounting bolts are inserted into the multiple sets of connecting holes. Pull ropes are installed below the multiple sets of mounting bolts. Two sets of mounting hole plates are welded to the upper part of the frame and the lower part of the mounting plate, with the upper set being one set. The lower part of the mounting box is welded with multiple sets of positioning cylinders, and T-shaped rods slide through the lower part of each set of positioning cylinders. Springs are fixedly installed between each set of positioning cylinders and each set of T-shaped rods. The lower ends of each set of T-shaped rods are fixedly connected to the upper part of the lower set of mounting boxes. Bidirectional lead screws are installed inside both sets of mounting boxes through bearings, and two sets of lead screw sleeves are sleeved on the side walls of both sets of bidirectional lead screws. Sleeve plates are fixedly sleeved on the side walls of all four sets of lead screw sleeves. Two sets of mounting covers are fixedly inserted through the far side of both sets of mounting boxes. Insert rods are welded to the far side of the two sets of sleeve plates on the same side. One end of each of the four sets of insert rods slides through the inner wall of the four sets of mounting covers.

[0007] Furthermore, the lower part of the mounting plate is welded with multiple sets of first connecting ears, the limiting ends of multiple sets of mounting bolts are all mounted with connecting shafts through bearings, and the lower sidewalls of multiple sets of connecting shafts are all sleeved with connecting plates through bearings. The lower part of multiple sets of connecting plates is welded with second connecting ears, and the two ends of a pull rope on the same side are respectively bolted to a set of first connecting ears and a set of second connecting ears on the same side.

[0008] Furthermore, both sets of mounting boxes have doors installed on their rear ends via hinges.

[0009] Furthermore, the two sets of bidirectional lead levers and the four sets of lead screw threads cooperate with each other.

[0010] Furthermore, a crossbar slides through the two sets of socket plates on the same side, and the two ends of the two sets of crossbars are respectively welded to the inner walls of the two sets of mounting boxes.

[0011] Furthermore, handwheels are fixedly installed at both ends of the two sets of bidirectional levers.

[0012] Compared with the prior art, this utility model provides a drone aerial photography gimbal with the following advantages: (1) This utility model adopts a mounting box and a mounting hole plate. Workers only need to move two sets of mounting boxes in opposite directions, adjust the position with the help of positioning cylinder, T-shaped rod and spring, and then drive the bidirectional screw lever by rotating the handwheel to insert or remove the plug rod into the mounting hole plate. This allows for quick connection or disassembly of the mounting plate and frame. This design eliminates the need to tighten multiple bolts one by one, reducing operation steps and time costs, allowing workers to maintain the shock absorption structure more efficiently, and improving the usability of the drone aerial photography gimbal.

[0013] (2) This utility model uses mounting bolts and pull ropes. When installing the mounting plate, the worker screws the mounting bolts into the threaded holes of the drone through the connecting holes. When disassembling, the removed mounting bolts will be pulled by the pull ropes to prevent them from falling too far from the mounting plate. At the same time, the setting of the first connecting ear, the second connecting ear and the connecting shaft ensures that the pull ropes do not rotate with the mounting bolts, which does not affect the normal use of the mounting bolts and can effectively prevent them from being lost.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a drone aerial photography gimbal is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to the accompanying drawings for details. Figure 1 , Figure 2 , Figure 4 and Figure 5A drone aerial photography gimbal includes a frame 1 and a mounting plate 2. Two sets of mounting boxes 3 are arranged between the frame 1 and the mounting plate 2. A first self-locking reversible motor 5 is fixedly installed on the inner bottom surface of the frame 1, and a concave frame 6 is fixedly installed at the output end of the first self-locking reversible motor 5. A mounting shaft 7 is installed inside the concave frame 6 via bearings. A camera 8 is fixedly sleeved on the side wall of the mounting shaft 7. A second self-locking reversible motor 9 is installed on the side wall of the concave frame 6. The output end of the second self-locking reversible motor 9 is connected to the mounting box 3 via a coupling. One end of the shaft 7 is fixedly connected to ensure that the output end of the second self-locking forward and reverse motor 9 can drive the shaft 7 to rotate. Multiple sets of connection holes 10 are provided on the upper part of the mounting plate 2, and mounting bolts 11 are inserted into the interior of each set of connection holes 10. Pull ropes 12 are installed below each set of mounting bolts 11. Two sets of mounting hole plates 4 are welded to the upper part of the frame 1 and the lower part of the mounting plate 2. Multiple sets of positioning cylinders 13 are welded to the lower part of the upper mounting box 3, and T-shaped rods 14 slide through the lower part of each set of positioning cylinders 13. Springs 15 are fixedly installed between the T-shaped rods 14 and the lower ends of the T-shaped rods 14. The lower ends of the T-shaped rods 14 are fixedly connected to the upper part of the lower mounting box 3. Two sets of double-acting screw levers 16 are installed inside the mounting boxes 3 via bearings. Two sets of screw sleeves 17 are fitted onto the side walls of the two sets of double-acting screw levers 16. Four sets of screw sleeves 17 are fixedly fitted onto the side walls of the four sets of screw sleeves 17. Two sets of mounting covers 25 are fixedly inserted through the opposite side of the two mounting boxes 3. Insert rods 20 are welded to the opposite side of the two sets of insert rods 20 on the same side. The ends slide through the inner walls of the four sets of mounting covers 25 respectively. Workers only need to move the two sets of mounting boxes 3 in opposite directions, adjust the position with the help of the positioning cylinder 13, T-shaped rod 14 and spring 15, and then drive the bidirectional screw lever 16 by rotating the handwheel to insert or remove the insertion rod 20 into the mounting hole plate 4. This allows for quick connection or disassembly of the mounting plate 2 and the frame 1. This design eliminates the need to tighten multiple bolts one by one, reducing operation steps and time costs, allowing workers to maintain the shock absorption structure more efficiently, and improving the practicality of the drone aerial photography gimbal.

[0020] Please see Figure 1 , Figure 3 and Figure 6The lower part of the mounting plate 2 is welded with multiple sets of first connecting ears 21. The limiting ends of multiple sets of mounting bolts 11 are all mounted with connecting shafts 22 through bearings. The lower side walls of multiple sets of connecting shafts 22 are all sleeved with connecting plates 23 through bearings. The lower part of multiple sets of connecting plates 23 is welded with second connecting ears 24. The two ends of a set of pull ropes 12 on the same side are respectively bolted to a set of first connecting ears 24 and a set of second connecting ears 24 on the same side. When the mounting plate 2 is installed, the worker screws the mounting bolts 11 into the threaded holes of the UAV through the connecting holes 10. When disassembling, the removed mounting bolts 11 will be pulled by the pull ropes 12 to prevent them from falling too far away from the mounting plate 2. At the same time, the setting of the first connecting ears 21, the second connecting ears 24 and the connecting shafts 22 ensures that the pull ropes 12 do not rotate with the mounting bolts 11, which does not affect the normal use of the mounting bolts 11 and can effectively prevent them from being lost.

[0021] Please see Figure 1 and Figure 2 Both sets of mounting boxes 3 have doors installed on their rear ends via hinges.

[0022] Please see Figure 1 and Figure 4 The two sets of bidirectional lead levers 16 and the four sets of lead screw sleeves 17 are threaded together to facilitate the adjustment of the working position of the four sets of lead screw sleeves 17.

[0023] Please see Figure 1 and Figure 4 A crossbar 19 slides through the two sets of socket plates 18 on the same side. The two ends of the two sets of crossbars 19 are welded to the inner walls of the two sets of mounting boxes 3 respectively. The crossbar 19 can ensure the stability of the movement of the two sets of socket plates 18 on the same side.

[0024] Please see Figure 1 Both ends of the two sets of bidirectional screw levers 16 are fixedly equipped with handwheels, and the four handwheels can assist the worker in rotating and using the two sets of bidirectional screw levers 16.

[0025] Working principle: Before actually using the drone aerial photography gimbal, first connect the first self-locking forward and reverse motor 5 and the second self-locking forward and reverse motor 9 to the drone controller via wires. When the frame 1 needs to be installed, the worker manually moves the two sets of mounting boxes 3 in opposite directions. At this time, multiple sets of positioning cylinders 13 and multiple sets of T-shaped rods 14 can compress multiple sets of springs 15. Then, the two sets of mounting boxes 3 can be moved between the frame 1 and the mounting plate 2. Then, the four sets of handwheels can be rotated by hand. The four sets of handwheels can drive the two sets of bidirectional screw levers 16 to rotate. The lead lever 16 and the four sets of lead screw sleeves 17 are threaded together. One set of bidirectional lead levers 16 on the same side can push the two sets of lead screw sleeves 17 on the same side closer or further apart. When the two sets of lead screw sleeves 17 on the same side move the two sets of insert rods 20 on the same side away from each other through the two sets of sleeve plates 18 on the same side, the two sets of insert rods 20 on the same side will be inserted into the interior of the two sets of mounting hole plates 4 on the same side respectively. At this time, the connection between the mounting plate 2 and the frame 1 is completed. The worker can rotate the four sets of handwheels in the opposite direction by hand to gradually move the four sets of insert rods 20 out of the interior of the four sets of mounting hole plates 4. The detachable frame 1, with its mounting box 3 and mounting hole plate 4, facilitates the disassembly and assembly of the shock-absorbing structure, improving the practicality of the drone aerial photography gimbal. When mounting plate 2 needs to be installed, workers can manually move it. When multiple sets of connecting holes 10 align with the drone's pre-drilled threaded holes, a set of mounting bolts 11 can be inserted into the threaded holes by rotating clockwise through the connecting holes 10. The remaining sets of mounting bolts 11 can be used in the same way. When mounting hole plate 4 needs to be disassembled, workers can sequentially rotate counterclockwise to remove multiple sets of mounting bolts 11. The multiple sets of mounting bolts 11 are pulled by multiple sets of pull ropes 12, preventing them from detaching too far from the mounting plate 2. Multiple sets of first connecting ears 21 and multiple sets of second connecting ears 24 serve to install multiple sets of pull ropes 12. Multiple sets of connecting shafts 22 prevent the pull ropes 12 from rotating with the mounting bolts 11. The mounting bolts 11 and pull ropes 12 prevent the loss of the bolt structure, ensuring the continued installation and use of the drone aerial photography gimbal.
