Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an angle adjustment mechanism for an aerial photography unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicle, referred to as "drone", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. It has no cockpit but is equipped with autopilot, program control device and other equipment. The aerial photography drone can adjust the angle of the camera by adjusting the drone when in use. However, in special areas with small space, the direction of the drone is not easy to adjust, so a camera angle adjustment mechanism is needed.

[0003] The existing angle adjustment mechanism has some disadvantages:

[0004] 1. The existing angle adjustment mechanism is not comprehensive enough to adjust the angle of the camera, so the captured image is incomplete and cannot meet the needs of users;

[0005] 2. When the camera is shooting, the drone's supporting legs can easily block the camera, causing defects in the images taken by the camera. Summary of the invention

[0006] The purpose of the present invention is to provide an angle adjustment mechanism for an aerial photography drone in order to solve the above-mentioned problem.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: an angle adjustment mechanism of an aerial photography drone, comprising a drone body, an adjustment component fixedly connected to the lower surface of the drone body, a camera arranged inside the adjustment component, a support component arranged on the lower surface of the drone body, and a wear-resistant pad fixedly connected to the lower surface of the support component;

[0008] The adjustment assembly includes two fixing plates fixedly connected to the lower surface of the drone body, the opposite surfaces of the two fixing plates are rotatably connected to the transmission shaft, the front surface of the fixing plates is fixedly connected to the longitudinal adjustment part, and the surface of the transmission shaft is fixedly connected to the transverse adjustment part.

[0009] The beneficial effects of the present invention are:

[0010] 1. The longitudinal adjustment part drives the transmission shaft to rotate, and then the transverse adjustment part installed on the transmission shaft rotates, so that the longitudinal angle on the horizontal plane is adjusted. The transverse angle of the camera on the horizontal plane is adjusted by the transverse adjustment part, so that the angle of the camera can be fully adjusted, solving the problem of incomplete image caused by incomplete angle adjustment;

[0011] 2. The support assembly can be controlled to retract to a position above the camera after the drone body is launched, preventing the support assembly from blocking the camera, thereby solving the problem of image defects caused by the drone's support legs blocking the camera.

[0012] Furthermore, the longitudinal adjustment part includes a mounting plate fixedly connected to the front side of the fixing plate, the front side of the mounting plate is fixedly connected to a longitudinal adjustment motor, the output end of the longitudinal adjustment motor passes through the back side of the mounting plate and is fixedly connected to an adjusting screw, one end of the adjusting screw close to the longitudinal adjustment motor is rotatably connected to the back side of the mounting plate, a moving block is threadedly connected to the surface of the adjusting screw, a rack is fixedly connected to the lower surface of the moving block, a sliding rod is fixedly connected to the side surface of the rack, and one end of the sliding rod away from the rack is slidably connected to the opposite surfaces of the two fixing plates.

[0013] The beneficial effect of the above further solution is that the adjusting screw is driven to rotate by the output end of the longitudinal adjustment motor, and then the moving block and the rack are driven to move under the limiting effect of the slide bar.

[0014] Furthermore, the longitudinal adjustment portion also includes a gear fixedly connected to the surface of the transmission shaft, and the gear is meshed with the rack.

[0015] The beneficial effect of the above further scheme is that through the meshing of the gear and the rack, the gear is driven to rotate when the rack moves, and then the transmission shaft is driven to rotate, and the angle of the lateral adjustment part in the horizontal and longitudinal directions is adjusted by the rotation of the transmission shaft.

[0016] Furthermore, the lateral adjustment part includes a rectangular frame fixedly connected to the surface of the transmission shaft, two extension plates are fixedly connected to the lower surface of the rectangular frame, the opposite surfaces of the two extension plates are rotatably connected to a rotating shaft, and the back side of the rear extension plate is fixedly connected to a lateral adjustment motor, and the output end of the lateral adjustment motor passes through the front side of the rear extension plate and is fixedly connected to one end of the rotating shaft.

[0017] The beneficial effect of the above further solution is that the rotating shaft is driven to rotate by adjusting the output end of the motor laterally.

[0018] Furthermore, a groove is provided on the surface of the rotating shaft, and the upper surface of the camera is fixedly connected to the inner top wall of the groove.

[0019] The beneficial effect of the above further solution is that the camera can be driven to rotate by the rotating shaft when the rotating shaft rotates, thereby adjusting the horizontal angle of the camera.

[0020] Furthermore, the support assembly includes a support rod, the top end of the support rod is rotatably connected to the lower surface of the drone body, the bottom end of the support rod is rotatably connected to a slider, the side of the slider is slidably connected to a slide, the center position of the inner bottom wall of the slide is fixedly connected to a double-output shaft motor, both output ends of the double-output shaft motor are fixedly connected to a threaded screw, and the end of the threaded screw away from the double-output shaft motor is rotatably connected to the inner wall of the slide.

[0021] The beneficial effect of the above further solution is that the threaded screw is driven to rotate by the output end of the double-output shaft motor.

[0022] Furthermore, a threaded hole is provided on the front side of the sliding block, and the inner wall of the threaded hole is threadedly connected to the surface of the threaded screw rod, and the threads on the two surfaces of the threaded screw rod have opposite rotation directions.

[0023] The beneficial effect of the above further scheme is: through the two threaded screws with opposite thread rotation directions, the two sliders are moved away from each other when they rotate, thereby increasing the height of the sliders, and the slideway is driven upward by the sliders to shrink the support assembly as a whole to prevent obstruction of the camera.
