Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the drone and its vibration reduction device will be described more fully below with reference to the relevant drawings. A preferred embodiment of the drone and its damping device is given in the accompanying drawings. However, the drone and its vibration damping device can be implemented in many different forms and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the drone and its vibration damping device more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "hor...

Abstract

The invention relates to an unmanned aerial vehicle and a vibration damper thereof. The vibration damper is used for connecting a fuselage of the unmanned aerial vehicle with an inertial measurement unit and comprises a corrugated pipe body, a first extension part and a second extension part, wherein the first extension part is arranged at the end part of the corrugated pipe body and is used for being connected with the fuselage; and the second extension part is arranged at the end part, far away from the first extension part, on the corrugated pipe body and is used for being connected with the inertial measurement unit. Effective vibration isolation can be simultaneously realized when vibration in three directions passes through the vibration damper, so that the measurement accuracy of the inertial measurement unit can be ensured, and the problem of poor measurement accuracy of the inertial measurement unit is solved; and during design, the inherent frequency corresponding to the translational vibration mode in three directions of the fuselage can be adjusted by changing the size, shape, wall thickness and other parameters of the corrugated pipe body.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and a vibration reduction device thereof. Background technique [0002] Drones contain some specific equipment that requires a stable environment in the work engineering, such as inertial measurement units. Affected by external air resistance and its own power plant, the UAV will generate vibration excitation during flight and transmit it to specific equipment, causing greater vibration on the specific equipment. [0003] The inertial measurement device is one of the core sensors of the drone. It is used to measure the angular velocity and acceleration of the drone's fuselage, and then calculate the drone's own attitude to ensure the safe navigation of the drone in the external environment. For inertial measurement units, measurement accuracy is one of the most critical indicators. The noise caused by the vibration of the fuselage is ...
