The invention discloses an electric variable-pitch propeller which comprises a blade assembly, a variable-pitch motor, a variable-pitch mechanism controlled by the variable-pitch motor and a driving device of the blade assembly, the variable-pitch mechanism comprises a sliding block provided with a sliding groove, a variable-pitch block is arranged in the sliding groove, and the variable-pitch block is connected with the blade assembly; wherein the variable-pitch motor is arranged at the end of the driving device. The vibration impact on the variable-pitch motor can be reduced, so that the damage of the variable-pitch motor caused by the vibration impact can be reduced, the service life of the variable-pitch motor is prolonged, and the reliability of the variable-pitch motor is improved; the variable pitch motor can be prevented from being directly exposed in the air, the influence of environmental factors on the variable pitch motor can be reduced, the service life of the variable pitch motor is further prolonged, the reliability of the variable pitch motor is further improved, and therefore the service life of the variable pitch propeller can be prolonged, and the variable pitch reliability of the variable pitch propeller can be improved.

    本发明公开了一种电动变距螺旋桨,包括桨叶总成、变距电机和受控于变距电机的变距机构以及桨叶总成的驱动装置,变距机构包括设有滑槽的滑块,滑槽内设有变距块,变距块与桨叶总成连接;其中:变距电机置于驱动装置端。本发明能够减小变距电机受到的振动冲击,从而能够减小变距电机因为振动冲击而出现的损坏,延长了变距电机的使用寿命和可靠性;能够避免变距电机直接暴露在空气中,还能够减少环境因素对变距电机带来的影响,进一步提高了变距电机的使用寿命和可靠性,从而能够提高变距螺旋桨的使用寿命和变距的可靠性。
