Problems solved by technology

However, due to the high-frequency vibration of the drone, this vibration will be transmitted to the camera. Since the driving force of the voice coil motor is too small to resist this vibration, it will cause the camera to vibrate back and forth during the focusing process. movement, resulting in inaccurate focus

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The drone provided by the embodiment of the present invention utilizes the electrification of the shape memory alloy wire to drive the lens assembly, and ensures that the lens assembly will not move due to the vibration of the power assembly.

[0026] The drone provided in this embodiment may specifically be an unmanned aerial vehicle,...

Abstract

An unmanned aerial vehicle, which includes: a fuselage and a camera assembly and a power assembly installed on the fuselage, the camera assembly includes a lens assembly and a drive assembly; wherein the lens assembly includes at least one lens; the drive assembly includes a base and a shape memory Alloy wire; the base is provided with a housing cavity, which is used to accommodate the lens assembly; the shape memory alloy wire is arranged on the base, and the shape memory alloy wire shrinks through electrification to drive the lens assembly in the housing cavity along the optical axis of the lens The preset displacement can be moved in one direction, and the lens assembly can keep a fixed position relative to the base after moving the preset displacement, so as to prevent the lens assembly from shaking the focal length caused by the vibration generated by the power assembly.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned aerial vehicle and a camera assembly. Background technique [0002] UAV is an unmanned carrier controlled by radio remote control equipment, such as unmanned aerial vehicles, unmanned vehicles, unmanned boats, etc. Due to the advantages of small size and flexible maneuverability, UAVs are used in aerial photography. fields are widely used. [0003] At present, the camera module used in the aerial photography process generally uses a voice coil motor as the lens driving device. However, due to the high-frequency vibration of the drone, this vibration will be transmitted to the camera. Since the driving force of the voice coil motor is too small to resist this vibration, it will cause the camera to vibrate back and forth during the focusing process. movement, resulting in inaccurate focus. Contents of the invention [0004] The drone and the camera assembly provid...
