The invention discloses a balance mechanism of a remote control coaxial double-rotor model helicopter, which comprises a rotor shaft. A mounting base is arranged below the rotor shaft; the mounting base is composed of a trigger disc, a transmission disc, a balance disc and a buffer air bag disc; trigger channels are evenly formed in the trigger disc; trigger devices and wind resistance devices arearranged in the trigger channels; a horizontally-arranged moving air channel is formed in the balance disc; and a balance weight device is arranged in the moving air channel. When the helicopter tilts, the rolling ball in the trigger disc can move, and the rolling ball triggers the abutting block; under the combined action of the abutting rod, the linkage rod and the vertical rod, the sealing column moves downwards, the abutting arc block drives the balance weight ball to move, the center of gravity of the helicopter which inclines originally shifts under the action of the balance weight ball, the helicopter gradually returns to the balance state, the arc-shaped wind resistance pieces are unfolded, the lift force generated by the lower blades is blocked, and therefore the lift force higher than the inclination is reduced.
本发明公开了遥控共轴式双旋翼模型直升机的平衡机构,包括旋翼轴,述旋翼轴下方设置有安装座,安装座由触发盘、传动盘、平衡盘和缓冲气囊盘组成,触发盘内均匀开设有触发通道,触发通道内设置有触发装置和风阻装置,平衡盘内开设有呈水平设置的移动气道,移动气道内设置有配重装置。本发明在直升机产生倾斜时,会使位于触发盘内的滚动球进行移动,使得滚动球触发抵触块,在抵触杆、联动杆和竖直杆的共同作用下,使得密封柱下移,使得抵触弧块带动配重球进行移动,使得原先产生倾斜的直升机在配重球的作用下,产生重心偏移,使得直升机逐渐的回复到平衡状态,弧形风阻片的展开会使得下桨叶产生的升力受阻,从而减小倾斜高出的升力。
