The invention relates to a fan vibration reduction mechanism, a fan assembly and an unmanned aerial vehicle. The vibration reduction mechanism is used for being arranged between a fan and a fan mounting seat, the vibration reduction mechanism comprises an elastic vibration reduction ring, and the vibration reduction ring is constructed to be capable of elastically sleeving the periphery of the fan and being clamped between the outer wall of the fan and the inner wall of the fan mounting seat, and is used for being extruded by the fan and the fan mounting seat to generate elastic pre-pressing force for abut-pressing the fan and the fan mounting seat after the fan is mounted. According to the technical scheme, the vibration reduction ring of the vibration reduction mechanism can be extruded and installed between the fan and the fan mounting seat through the elastic effect of the vibration reduction ring, the mounting process is simple and convenient, high reliability is achieved, and it is guaranteed that the fan is not prone to falling off. Moreover, the extrusion mounting mode does not have great influence on the damping effect of the vibration reduction ring, so that the vibration reduction and noise reduction effects of the vibration reduction mechanism are effectively ensured, and the influence of vibration on the work of other parts around the fan is avoided.
Description
technical field [0001] The present disclosure relates to the field of fan technology, and in particular, to a fan vibration reduction mechanism, a fan assembly and an unmanned aerial vehicle. Background technique [0002] At present, fans are generally used as important heat dissipation devices in various fields, and are used to dissipate heat from heat generating devices of applied products, so as to avoid affecting use due to temperature rise of products. For example, in the field of drones, the body will be equipped with power devices that provide functions for drones, such as central processing units and part of the driving power supply for drones. The temperature of power devices will increase with long-term work, so , Fans are often installed at positions corresponding to power devices for heat dissipation. Since the fan is installed on the body of the UAV, the rotation of the fan will cause the body to vibrate and generate noise, and when precision devices (such as U...
