DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example 1: This example aims to solve the problem in the prior art that when calibrating a drone, the drone will generate a large impact force when landing. If the impact force is not buffered, it is very likely that the calibration result will be inaccurate and the equipment will be damaged. Figures 1-6 A turntable device for compensation calibration of a drone includes a placement plate 110 and a calibrator 160. A calibration groove 130 is opened in the middle of the placement plate 110, a fixing plate 120 is installed on the side of the placement plate 110, a calibrator 160 is provided at the bottom of the placement plate 110, a base plate 150 is fixedly installed at the bottom of the calibrator 160, a buffer assembly 530 is provided in the middle of the base plate 150, a support column 170 is connected to the middle of the base plate 150 and a support assembly 540 is provided in the middle of the support column 170.
[0025] The buffer assembly 530 includes a buffer groove 300 opened in the middle of the bottom plate 150, and a top plate 400 is fixedly installed on the side of the buffer groove 300. A connecting block 430 is slidably connected to the side of the top plate 400. A moving rod 420 is installed on the side of the connecting block 430. The middle part of the moving rod 420 is hinged to the connecting shaft 311. When subjected to downward force, the moving rod 420 will rotate due to the setting of the connecting shaft 311, so that the buffer plate 440 falls and plays a buffering role. A connecting piece 330 is hinged at the bottom of the moving rod 420, and a reinforcement block 310 is hinged on the side of the connecting piece 330. The reinforcement block 310 is fixedly installed at the bottom of the buffer groove 300.
[0026] When the drone needs to be calibrated, first ensure that the turntable device is placed on a level and stable surface, check whether the calibrator 160 is correctly installed at the bottom of the placement plate 110, and ensure that the calibrator 160 is in standby mode, confirm that all components such as the buffer assembly 530 and the support assembly 540 are intact and in the correct position, and the operator places the drone steadily in the calibration slot 130 to ensure that the drone is aligned with the calibrator 160.
[0027] First, the fixing plate 120 forms a stabilizing effect on the entire device. Secondly, when the drone falls, the drone is parked on the placement plate 110 so as to proceed to the next step to prevent the drone from moving during the calibration process. The calibrator 160 is started to start the preliminary calibration process. The calibrator 160 contacts the drone through the buffer component 530 at the bottom and preliminarily adjusts the posture of the drone. The top plate 400, the connecting block 430 and the moving rod 420 in the buffer component 530 start to work. Then, when gravity presses down, the connecting block 430 will push the moving rod 420 to rotate, causing the buffer plate 440 to fall and contact the bottom plate 150. At this time, the buffer plate 440 will squeeze the spring 500, causing the spring 500 to be compressed, thereby forming a buffering effect.
[0028] The calibrator 160 is adjusted according to the specific model and calibration requirements of the drone through the limit slot 180, the first slider 200, the second slider 233, the connecting plate 210 and the rotating rod 230 in the support assembly 540. When the drone lands, the weight of the drone itself is large. If it is not supported, the calibrator 160 may be damaged. When the drone lands, the support column 170 will first support the device itself. When the drone is completely landed, the support column 170 is set with the contact plate 270 and the rotating rod 250 and the rotating rod 230. When the gravity is too large, the rotating rod 230 and the rotating rod 250 will rotate through the fixed shaft 240. During the rotation process, the first slider 200 and the second slider 233 will slide on the The UAV slides in the groove 190, which plays a supporting role on the one hand and a buffering protection role on the other hand to achieve precise calibration. The rotating rod 230 is connected to the rotating rod 250 through the fixed shaft 240. The contact plate 270 at the end of the rotating rod 250 contacts the UAV to perform fine posture adjustment. When the calibrator 160 shows that the UAV posture is adjusted in place, the calibration process is completed. The calibration data can be stored in the calibrator 160 for subsequent analysis and use. The operator removes the UAV from the calibration groove 130 to complete the calibration process, checks whether the UAV is damaged, ensures that the UAV is in good condition, turns off the calibrator 160, and restores the turntable device to its initial state to prepare for the next calibration. If necessary, the turntable device is cleaned and maintained.
[0029] In this embodiment: by arranging a calibration groove 130 and a calibrator 160 on the placement plate 110, accurate calibration of the UAV can be achieved, and the flight stability and navigation accuracy of the UAV can be improved. By arranging the buffer component 530 in the middle of the bottom plate 150, the vibration generated by the UAV during placement or movement can be absorbed and reduced, and the sensitive components inside the UAV can be protected from damage. By arranging the support column 170 and the support component 540, the stability of the entire turntable device is improved, and the safety of the UAV during the calibration process is ensured. By arranging structures such as the moving rod 420, the connecting block 430, and the reinforcement block 310, the device can be adjusted according to different UAV models, thereby improving the adaptability of the device.
[0030] Example 2: This example is intended to promote the solution of the safety problem of the existing technology equipment during landing. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-6 A stabilizing plate 520 is fixedly installed on the side of the moving rod 420, and a fixing frame 490 is hinged in the middle of the stabilizing plate 520.
[0031] A spring 500 is installed in the middle of the fixed frame 490, and a push rod 480 is inserted in the middle of the fixed frame 490. The push rod 480 is connected to the spring 500. The side of the push rod 480 is fixedly connected to the push block 470. The side of the push block 470 is hinged to the push plate 450. The push plate 450 is fixedly connected to the buffer plate 440. The buffer plate 440 is intermittently in contact with the bottom of the buffer groove 300.
[0032] The support assembly 540 includes a limit groove 180 opened in the middle of the support column 170, a slide groove 190 is opened at the bottom of the support column 170, and the middle of the slide groove 190 is slidably connected to the first slider 200 and the second slider 233. The side of the first slider 200 is fixedly connected to the connecting plate 210, and the middle of the connecting plate 210 is hinged with a rotating rod 230. The middle of the rotating rod 230 is hinged with a rotating rod 250 through the installation shaft 312. The rotating rod 230 is connected to the side of the rotating rod 250. Torsion spring 234, a buffer cylinder 231 is fixedly connected to the side of the first slider 200, a buffer rod 232 is inserted in the middle of the buffer cylinder, and a second slider 233 is fixedly connected to the side of the buffer rod 232. The buffer cylinder 231 and the buffer rod 232 are both made of rubber material. When subjected to force and pressed downward, the buffer rod 232 and the buffer cylinder 231 will expand and contract. If there is no force, the buffer rod 232 will reset due to the rubber material and the setting of the torsion spring 234, thereby providing buffering protection.
[0033] When the rotating rod 230 and the rotating rod 250 are pressed down, the first slider 200 and the second slider 233 move relative to each other in the slide groove 190. When pressed down by force, the mounting shaft 312 plays a fixing role on the one hand. On the other hand, when the rotating rod 230 and the rotating rod 250 are forced to be pressed down, the rotating rod 230 and the rotating rod 250 will rotate through the mounting shaft 312. The end of the rotating rod 250 is hinged to the contact plate 270 through the rotating shaft 260. The side of the contact plate 270 is fixedly connected to the connecting rod 280, and the side of the connecting rod 280 is sleeved with a buffer sleeve 290.
[0034] In this embodiment: by setting structures such as the limit plate 340, the support rod 360, and the rotating bead 370, the positioning and fixation of the drone during the calibration process are made easier. By adopting settings such as hinges and fixed connections between the components, disassembly and assembly are facilitated, and maintenance costs are reduced. By setting components such as the reinforcement block 310, the stabilizing plate 520, and the spring 500, the impact resistance and durability of the device are enhanced, and the service life of the equipment is extended. By setting structures such as the push rod 480, the push block 470, and the push plate 450, an automated calibration process can be achieved, reducing manual intervention, thereby improving work efficiency.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
