The invention discloses a cargo locking and unlocking mechanism for cargo throwing of an unmanned helicopter. A linear motor is mounted on a mounting bottom plate, the axial direction of a driving shaft of the linear motor is set to be the front-back direction, the axial direction of a transmission push rod is set to be the left-right direction, and a rotating shaft of the linear motor is connected with a middle section of the transmission push rod; and crank arm transmission mechanisms comprise connecting seats and lock pins with the axial direction being the left-right direction, the two connecting seats are connected with the two ends of the transmission push rod respectively, and the crank arm transmission mechanisms can drive the corresponding lock pins to move left and right when theconnecting seats move front and back. According to the cargo locking and unlocking mechanism, the linear motor is adopted as driving equipment of the cargo locking and unlocking mechanism, the transmission push rod is conveniently and directly pushed to move front and back, the two crank arm transmission mechanisms are driven by the same transmission push rod to act synchronously, the lock pins at the two sides are driven to be in a locked or unlocked state at the same time, and the stability during locking is improved; and compared with independent control, the cost of one linear motor is saved, and the power consumption of the system is effectively reduced.
本发明公开了一种无人直升机货物投放用货物锁定及解锁机构,直线电机安装在安装底板上,设直线电机的驱动轴的轴向为前后方向,传动推杆的轴向为左右方向,直线电机的转轴与传动推杆的中段连接,拐臂传动机构包括连接座和轴向为左右方向的锁销,两个连接座分别与传动推杆的两端连接,拐臂传动机构能够在连接座前后移动时驱动对应的锁销左右移动。本发明通过采用直线电机作为货物锁定及解锁机构的驱动设备,便于直接推动传动推杆前后移动,通过同一传动推杆驱动两个拐臂传动机构同步动作,带动两侧的锁销同时处于锁定或解锁状态,增大了锁定时的稳定性,相比独立控制还节省了一个直线电机的成本,并有效降低了系统的功耗。
