Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle camera photography, and in particular to a large-viewing-angle processing device for an unmanned aerial vehicle camera lens. Background Art

[0002] Unmanned aerial vehicles, or UAVs for short, are a new concept of aircraft that is developing rapidly. They are widely used because of their flexibility, fast response, no need for manual driving, low operating requirements, and the ability to carry a variety of small devices or objects. The purpose of the design of the UAV camera lens wide-angle processing device is to achieve efficient aerial photography tasks on UAVs, and to be able to shoot wide-angle landscapes, buildings, urban landscapes and other scenes that require wide-angle coverage, providing technical support for aerial photography and monitoring applications.

[0003] After searching, the Chinese patent publication number CN 205366060 U discloses "a drone for day and night photography, including a fuselage, an arm, a propeller, a shock-absorbing frame fixedly mounted on the head of the fuselage and with a servo frame and a bearing frame vertically mounted on both sides, a gimbal including a single-axis servo steering gear, an instrument cabin and a rotating shaft, a gyroscope, visible light and infrared light camera devices are installed in the instrument cabin, the lens of the instrument cabin faces the outside of the fuselage, and is movably installed between the servo frame and the bearing frame through a servo steering gear shaft inserted on one side and a rotating shaft inserted on the other side, so that the drone can observe and photograph day and night from a first-person perspective no matter what kind of flying action it performs, and assist the operator to stably control the drone and obtain the desired observation and photography angles to obtain the desired information; the utility model requires a small number of components to achieve these goals, has a simple structure, is easy to install, and is reliable to use, and therefore has great value for promotion and application."

[0004] The above patent installs a gimbal with a built-in gyroscope on the head of the fuselage and can be controlled by a single-axis servo steering gear, so that the drone can obtain a stable observation and shooting angle from the first perspective. By optimizing the drone provided by the utility model, it is possible to solve the problems of fixed-arm drones in the prior art that they occupy a large space when stored, have poor portability and concealment, etc. However, in the above patent, since the position of the camera device is fixed, the angle of the camera device cannot be adjusted according to the specific shooting environment and requirements, and further, high-quality shooting materials cannot be obtained. In addition, due to the lack of protective devices in the above patent, the drone may be hit by unidentified flying objects during the entire shooting process, which will further cause damage to the camera device and ultimately affect the entire shooting progress. Utility Model Content

[0005] The utility model provides a large viewing angle processing device for a drone camera lens, which solves the problem in the prior art that a single fiber is difficult to pass through a filter hole independently.

[0006] The technical solution of the utility model is as follows: a large-angle processing device for a drone camera lens, comprising a drone body, a protective shell is installed at the lower end of the drone body, and a mounting plate is installed inside the protective shell, a camera is installed on the lower surface of the mounting plate, a connecting rod is fixedly connected to the center position of the inner wall of the upper end of the protective shell, a first linkage assembly is installed inside the protective shell, and the first linkage assembly includes a first motor installed on the inner wall of the upper end of the protective shell, a first main gear is installed at the lower end of the first motor, a first linkage block is installed on the outer wall of the mounting plate, and a first connecting block is installed at the other end of the first connecting block, the other end of the first connecting block is fixedly connected to the first connecting block, and the upper end of the first connecting block is fixedly connected to the first connecting sleeve rod, and the other end of the first connecting sleeve rod is fixedly connected to the first sub-gear, a second linkage assembly is installed inside the protective shell, and the second linkage assembly includes a first motor installed inside the upper end of the protective shell. The second gear is connected with the gear train of the second transmission gear of the present invention, and the gear train of the second transmission gear is connected with the gear train of the second transmission gear of the second transmission gear.

[0007] Preferably, the buffer structure includes an installation box installed on the outer wall of the protective shell, and a partition is installed inside the installation box, and connecting rods are fixedly connected on both sides of the partition, and the other ends of the connecting rods are connected to the inner wall of the installation box, and a slider is slidably installed on the connecting rod, and a spring is fixedly connected between the slider and the inner wall of the installation box, the spring sleeve is arranged on the outside of the connecting rod, and a movable block is installed on the slider, and the other end of the movable block is connected to the inner wall of the protective plate. The setting of the buffer structure can offset the impact force caused by flying objects during the shooting process, and effectively ensure that the camera can complete the entire shooting process.

[0008] Preferably, the first main gear is meshed with the first sub-gear, the second main gear is meshed with the second sub-gear, and the third main gear is meshed with the third sub-gear. When the first motor is started, the first main gear starts to drive the first sub-gear to rotate, so that the first linkage assembly starts to move. Similarly, when the second motor and the third motor are started, the second linkage assembly and the third linkage assembly also start to move, ultimately ensuring that the shooting angle of the camera can be adjusted normally.

[0009] Preferably, the first sub-gear, the first connecting sleeve rod and the first connecting block are all rotatably mounted on the outside of the connecting rod, the second sub-gear, the second connecting sleeve rod and the second connecting block are all rotatably mounted on the outside of the connecting rod, and the third sub-gear and the third connecting block are all rotatably mounted on the outside of the connecting rod. By rotating the first sub-gear, the first connecting sleeve rod and the first connecting block on the outside of the connecting rod, the first linkage assembly can start to operate, and further can adjust the shooting angle of the camera. Similarly, the second linkage assembly and the third linkage assembly can also adjust the shooting angle of the camera, thereby ensuring the normal progress of the entire shooting process.

[0010] Preferably, one end of the first linkage block is hingedly connected to the first connecting block, the other end of the first linkage block is hingedly connected to the mounting plate, one end of the second linkage block is hingedly connected to the second connecting block, the other end of the second linkage block is hingedly connected to the mounting plate, one end of the third linkage block is hingedly connected to the third connecting block, and the other end of the third linkage block is hingedly connected to the mounting plate. After the first motor, the second motor and the third motor are started respectively, the first linkage block, the second linkage block and the third linkage block start to move respectively, which can further drive the mounting plate to move, and finally complete the adjustment of the angle of the camera on the mounting plate.

[0011] Preferably, the first linkage assembly, the second linkage assembly and the third linkage assembly are evenly distributed inside the protective shell, and the angle of the camera can be adjusted by the first linkage assembly, the second linkage assembly and the third linkage assembly, and can further adapt to different shooting environments.

[0012] Preferably, one end of the movable block is hingedly connected to the inner wall of the protective plate, and the other end of the movable block is hingedly connected to the outer wall of the protective shell.

[0013] Preferably, the four protective plates are all made of rubber material. The rubber protective plates have a good buffering effect. When a flying object hits the protective plate, the protective plate can reduce the force by generating deformation, further ensuring the normal operation of the camera.

[0014] The technical effects and advantages of the utility model are as follows: when it is necessary to adjust the angle of the shooting device, it is only necessary to start the first motor, the second motor and the third motor through the control device. At this time, the first main gear will drive the first sub-gear to start rotating, and then the first linkage block starts to move under the action of the first connecting sleeve, the first connecting block and the first connecting block. Similarly, the second linkage assembly and the third linkage assembly also start to move. Because the mounting plate and the first linkage block, the second linkage block and the third linkage block are all hingedly connected, the angle of the camera on the mounting plate can be adjusted under the action of the first linkage assembly, the second linkage assembly and the third linkage assembly, so that it can adapt to different shooting environments. In addition, a protective shell is installed on the periphery of the camera, and the outer walls of the protective shell are connected to the protective plate through multiple buffer structures. When the protective plate is subjected to external force, the force will be transmitted to the spring through the movable block and the slider, so that the spring begins to compress, and further the impact force received by the protective plate can be buffered, and finally the camera can be protected for normal shooting.
