[0002] With the rapid development of drone technology, its application in fields such as aerial photography, surveying, inspection, and agricultural plant protection is becoming increasingly widespread. When performing missions, drones typically need to carry various mission equipment (such as cameras, infrared thermal imagers, and lidar), which are generally mounted on the drone body via gimbals to achieve stable shooting and multi-angle control.

[0003] Traditional gimbal structures mostly use rigid connections, meaning that the drone and the gimbal are usually fastened together with bolts or other fasteners. When rapid deployment and maintenance of the equipment are required, it is not convenient to quickly disassemble and assemble the gimbal. In addition, due to the lack of shock-absorbing structure design in the traditional gimbal design, it is easy to cause blurry images or data errors of the mounted equipment, which affects the quality of the mission.

[0026] Combination Figures 1 to 5As shown in the figure, this application discloses a gimbal that facilitates quick assembly and disassembly of a drone. The gimbal includes a multi-axis boom assembly 1, a control box 2 rotatably connected to the upper end of the multi-axis boom assembly 1, a shock-absorbing platform 3 fastened to the control box 2, a support platform 4 installed on the shock-absorbing platform 3, quick-release seats 5 disposed on both sides of the support platform 4, and a quick-release crossbeam 6 cooperating with the quick-release seats 5; a connecting seat 61 for easy fastening to the drone 7 is provided in the middle of the quick-release crossbeam 6.

[0027] The gimbal designed with this structure is connected to the bottom of the drone 7 via the connecting seat 61 in the middle of the quick-release crossbeam 6. When maintenance is required on the equipment mounted on the gimbal, the drone 7 can be easily and quickly disassembled and assembled with the gimbal through the connection between the quick-release crossbeam 6 and the quick-release seat 5.

[0028] Because the gimbal is equipped with a shock-absorbing platform 3, the vibration caused to the gimbal by the drone 7 during flight can be effectively reduced, thereby avoiding any impact on the image clarity of the equipment mounted on the gimbal.

[0029] Specifically, the shock-absorbing platform 3 includes a first support plate 31 and a second support plate 32 arranged in parallel intervals, and a plurality of shock absorbers 33 disposed between the first support plate 31 and the second support plate 32. The upper and lower ends of the plurality of shock absorbers 33 are respectively connected to the corresponding first support plate 31 and the second support plate 32. The shock absorber 33 includes a shock absorber ball 331 and a connecting rod extending from both ends of the shock absorber ball 331 in a coaxial integral shape. The end of the connecting rod away from the shock absorber ball 331 is provided with a positioning cover 332. Preferably, the shock absorber ball 331, the connecting rod and the positioning cover 332 are integrally molded from rubber with good shock absorption effect. During installation, the positioning cover 332 disposed at both ends of the connecting rod can be deformed and passed through the positioning holes opened on the first support plate 31 and the second support plate 32 respectively, and installed between the first support plate 31 and the second support plate 32. After installation, the positioning cover 332 at the upper end of the shock absorber 33 is pressed between the bearing platform 4 and the first support plate 31. The bearing platform 4 is fastened to the first support plate 31 by screws.

[0030] As a preferred embodiment, four shock absorbers 33 are provided and are respectively installed at the four corners of the first support plate 31 and the second support plate 32, so as to achieve a better shock absorption and vibration isolation effect on the vibration from the UAV 7 during operation.

[0031] More specifically, to facilitate easy assembly and disassembly between the quick-release beam 6 and the quick-release seat 5, two quick-release seats 5 installed on opposite sides of the support platform 4 are horizontally provided with a sliding groove 51 on the same side. A pin 8 is vertically provided above the sliding groove 51 and passes through the sliding groove 51. Both ends of the quick-release beam 6 are provided with a fixed end that facilitates sliding engagement with the sliding groove 51. The fixed end is provided with a clearance hole to facilitate the insertion of the pin. In addition, to prevent the pin from loosening during use, a spring is sleeved on the upper end of the pin, and an external thread is provided on the lower end of the pin. The lower end of the pin inserted into the clearance hole is threadedly connected to the quick-release seat 5 and is tensioned by the spring force above, thereby achieving a stable and reliable connection between the quick-release beam 6 and the quick-release seat 5. When it is necessary to separate the quick-release beam 6 from the quick-release seat 5, the pin can be manually unscrewed.

[0032] Furthermore, the aforementioned control box 2 includes a housing and an electronic control device disposed within the housing cavity. The port of the housing is positioned upward and is fastened to the lower bottom surface of the second support plate 32. Preferably, the upper port of the housing has a horizontally extending mounting flange, which allows for the installation and fixation between the housing and the second support plate 32.

[0033] Furthermore, the aforementioned multi-axis boom assembly 1 includes an L-shaped drive arm 11, a first drive motor 12 and a second drive motor 13 disposed at both ends of the drive arm 11, and a boom 14 connected to the drive end of the second drive motor 13; the axes of the drive shafts of the first drive motor 12 and the second drive motor 13 are perpendicular to each other. Preferably, a camera is mounted at the end of the boom 14, thereby enabling adjustment of the camera's X-axis and Y-axis directions through the action of the first drive motor 12 and the second drive motor 13.

[0034] Furthermore, as another preferred embodiment of this invention, the connector is also provided with a conductive hole, which is electrically connected to the control box 2 via a wire and cooperates with a conductive pin provided at the bottom of the drone 7, thereby realizing the electrical connection between the control box 2 and the drone 7.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
