Abstract
Description
Technical Field
[0001] This utility model relates to the field of surveying and mapping drone technology, specifically a drone telescopic surveying and mapping mechanism. Background Technology
[0002] As an emerging tool for geographic information acquisition, surveying drones are widely used in fields such as remote sensing, photogrammetry, and map making. These drones are typically equipped with high-precision cameras, lidar, and other sensors to achieve efficient and accurate acquisition of geographic information.
[0003] However, traditional surveying drones have some limitations in use:
[0004] Cameras are typically mounted externally on the bottom of drones. While this exposed design can improve data acquisition efficiency, when the drone is not in operation, the exposed state of the camera is easily affected by the external environment, increasing the risk of equipment damage. Furthermore, the exposed camera increases aerodynamic drag, affecting the drone's flight stability and endurance. Utility Model Content
[0005] The purpose of this invention is to provide a telescopic surveying mechanism for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A UAV telescopic surveying mechanism includes a UAV base plate with a circular groove on its bottom surface and a mounting mechanism fixedly mounted on its top surface. The mounting mechanism includes a rotating component fixedly mounted on the top surface of the UAV base plate, in which a sphere is rotatably mounted. The sphere has a mounting groove on its surface, in which a telescopic mechanism is fixedly mounted. The front end of the telescopic mechanism is fixedly connected to the mounting component, and a camera is detachably mounted on the mounting component.
[0008] The interior of the groove is spherical, and the inner wall of the groove slides in contact with the spherical surface of the sphere.
[0009] Furthermore, the mounting groove includes a cylindrical cavity, the diameter of which is equal to the diameter at the bottom of the circular groove;
[0010] A positioning and mounting groove coaxial with the cylindrical cavity is provided on the inner bottom surface of the cylindrical cavity.
[0011] The inner wall of the cylindrical cavity has an annular groove near the opening.
[0012] Furthermore, the telescopic mechanism includes an electric telescopic rod, the fixed part of which is slidably engaged in the positioning and mounting groove, and two protruding plates are fixedly connected to the middle position of the outer periphery of the fixed part of the electric telescopic rod. The protruding plates are fixedly connected to the inner bottom surface of the cylindrical cavity by bolts.
[0013] Furthermore, the mounting assembly includes a sliding plate, and the telescopic end of the electric telescopic rod is fixedly connected to the sliding plate, with the outer periphery of the sliding plate in sliding contact with the inner wall of the annular groove;
[0014] Multiple evenly distributed spring dampers are fixedly installed on the side of the slide plate away from the electric telescopic rod. The ends of the multiple spring dampers away from the slide plate are fixedly connected to a mounting plate. The camera is detachably fixedly installed on the side of the mounting plate away from the spring dampers.
[0015] The outer periphery of the mounting plate slides in contact with the inner wall of the annular groove.
[0016] Furthermore, the rotating assembly includes two mounting plates fixedly mounted on the top surface of the drone's base plate. The two mounting plates are symmetrically distributed on both sides of the sphere. A rotating shaft is rotatably mounted on the side of the mounting plate near the sphere. The end of the rotating shaft away from the mounting plate is fixedly connected to the spherical surface of the sphere, and the axis of the rotating shaft is aligned with the center of the sphere.
[0017] A motor is fixedly mounted on the side of the mounting plate away from the sphere. The end of the shaft at the corresponding position near the motor rotates through the mounting plate and is fixedly connected to the output shaft end of the motor.
[0018] Furthermore, a spherical cover is provided directly above the sphere, and the spherical cover slides in contact with the spherical surface of the sphere;
[0019] A support rod is fixedly connected between the outer spherical surface of the spherical cover and the top of each of the two mounting plates.
[0020] The beneficial effects of this utility model are:
[0021] 1. When surveying is required, the opening of the cylindrical cavity is coaxially aligned with the circular groove. The electric telescopic rod extends, causing the mounting assembly to move in the opposite direction to the opening of the cylindrical cavity, allowing the camera to extend through the cylindrical cavity and circular groove to the underside of the drone's base plate. When surveying is not required, the electric telescopic rod first retracts the camera back into the cylindrical cavity. Then, the motor drives the rotating shaft to rotate, causing the sphere to rotate 180 degrees. At this point, the opening of the cylindrical cavity is located above the drone's base plate, i.e., inside the drone. Therefore, this invention, through the coordinated design of the sphere, rotating assembly, motor, and telescopic mechanism, allows the camera to be exposed for efficient surveying during operation, while retracting into the drone when not in use, thus effectively protecting the equipment. Furthermore, when not in use, the portion of the sphere exposed through the circular groove is spherical, reducing aerodynamic drag and improving the drone's flight stability and endurance.
[0022] 2. The mounting assembly of this utility model, through the arrangement of the sliding plate, spring damper, and mounting plate, can not only install the camera but also provide a certain degree of shock absorption for the camera, thereby improving the protection performance of the camera.
[0023] 3. This utility model, through the design of the spherical cover, can seal the opening of the cylindrical cavity when the sphere is in the closed state, effectively preventing dust, dirt, and other contaminants from entering the lens and improving the cleanliness of the camera. At the same time, sealing the opening prevents moisture and humidity from entering the device, reducing the risk of equipment damage caused by dampness. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1: Please refer to Figures 1-3 In this embodiment of the utility model, a telescopic mapping mechanism for unmanned aerial vehicles (UAVs) includes a UAV base plate 1, a circular groove 2 on the bottom surface of the UAV base plate 1, and an installation mechanism fixedly installed on the top surface of the UAV base plate 1. The installation mechanism includes a rotating component fixedly installed on the top surface of the UAV base plate 1, a sphere 3 rotatably installed in the rotating component, an installation groove on the spherical surface of the sphere 3, a telescopic mechanism fixedly installed in the installation groove, an installation component fixedly connected to the front end of the telescopic mechanism, and a camera 18 detachably fixedly installed on the installation component.
[0032] The interior of the circular groove 2 is a spherical surface, and the inner wall of the circular groove 2 is in sliding contact with the spherical surface of the sphere 3.
[0033] The mounting groove includes a cylindrical cavity 9, the diameter of which is equal to the diameter of the bottom end of the circular groove 2.
[0034] A positioning and mounting groove 10, coaxial with the cylindrical cavity 9, is provided on the inner bottom surface of the cylindrical cavity 9;
[0035] An annular groove 14 is formed on the inner wall of the cylindrical cavity 9 near the opening.
[0036] The telescopic mechanism includes an electric telescopic rod 11. The fixed part of the electric telescopic rod 11 is slidably engaged in the positioning and mounting groove 10. Two protruding plates 12 are fixedly connected to the middle position of the outer periphery of the fixed part of the electric telescopic rod 11. The protruding plates 12 are fixedly connected to the inner bottom surface of the cylindrical cavity 9 by bolts 13.
[0037] The rotating assembly includes two mounting plates 4 fixedly mounted on the top surface of the drone base plate 1. The two mounting plates 4 are symmetrically distributed on both sides of the sphere 3. A rotating shaft 5 is rotatably mounted on the side of the mounting plate 4 near the sphere 3. The end of the rotating shaft 5 away from the mounting plate 4 is fixedly connected to the spherical surface of the sphere 3. The axis of the rotating shaft 5 is aligned with the center of the sphere 3.
[0038] A motor 6 is fixedly mounted on the side of a mounting plate 4 away from the sphere 3. The end of a rotating shaft 5 at the corresponding position near the motor 6 rotates through the mounting plate 4 and is fixedly connected to the output shaft end of the motor 6.
[0039] Among them, motor 6 and electric telescopic pole 11 are connected to the control system of the drone.
[0040] When using this utility model:
[0041] When surveying is required, the opening of the cylindrical cavity 9 is aligned coaxially with the circular groove 2, and the electric telescopic rod 11 is extended to drive the mounting components to move towards the opening of the cylindrical cavity 9, so that the camera 18 extends through the cylindrical cavity 9 and the circular groove 2 to the bottom of the drone base plate 1.
[0042] When surveying is not required, first control the electric telescopic rod 11 to drive the camera 18 to reset and retract into the cylindrical cavity 9, then control the motor 6 to drive the rotating shaft 5 to rotate, so that the sphere 3 rotates 180 degrees. At this time, the opening of the cylindrical cavity 9 is located above the drone base plate 1, that is, inside the drone.
[0043] Therefore, this utility model, through the coordinated arrangement of the sphere 3, rotating component, motor 6 and telescopic mechanism, allows the camera 18 to be exposed for efficient mapping when in operation, and to be retracted into the drone when not in operation, thereby achieving effective protection of the equipment.
[0044] Furthermore, when not in operation, the part of the sphere 3 exposed through the circular groove 2 is a spherical surface, which can reduce aerodynamic drag and improve the flight stability and endurance of the drone.

The ends of the multiple spring dampers 16 away from the slide plate 15 are fixedly connected to the mounting plate 17. A camera 18 is detachably fixedly installed on the side of the mounting plate 17 away from the spring dampers 16.
[0047] The outer periphery of the mounting plate 17 slides in contact with the inner wall of the annular groove 14.
[0048] The mounting components, including the slide plate 15, spring damper 16, and mounting plate 17, enable the camera 18 to be installed while also providing a certain degree of shock absorption, thus improving the protection performance of the camera 18.
[0049] Example 3: Please refer to Figure 1 and Figure 2 Based on embodiment 1, a spherical cover 8 is provided directly above the sphere 3, and the spherical cover 8 slides in contact with the spherical surface of the sphere 3;
[0050] Support rods 7 are fixedly connected between the outer spherical surface of the spherical cover 8 and the top of the two mounting plates 4.
[0051] By using the spherical cover 8, the opening of the cylindrical cavity 9 can be sealed when the sphere 3 is closed, effectively preventing dust, dirt, and other contaminants from entering the lens and improving the cleanliness of the camera. At the same time, sealing the opening can prevent moisture and humidity from entering the device, reducing the risk of equipment damage caused by moisture.
