手推式自驱行进机器

本发明公开了一种手推式自驱行进机器，包括：手推式自驱行进机器具有自驱前进模式和自驱后退模式；自驱前进模式时，自行走电机驱动轮子沿第一方向转动；当自行走电机关闭使手推式自驱行进机器退出自驱前进模式时，用户向前推动手推式自驱行进机器使轮子沿第一方向转动；离合器解锁进入解锁状态；自驱后退模式时，自行走电机驱动轮子沿与第一方向相反的第二方向转动；当自行走电机关闭使手推式自驱行进机器退出自驱后退模式时，用户向后推动手推式自驱行进机器使轮子沿第二方向转动；离合器解锁进入解锁状态。本发明的手推式自驱行进机器在自行走马达关闭后，用户只需较小的力即可推动或拉动手推式自驱行进机器。 Provided is a hand-powered self-driven travelling machine that comprises a clutch (50a) having a driving state where a motor (40) drives wheels (30) to rotate and an unlocked state where the wheels (30) freely rotate relative to the motor (40). The clutch (50a) comprises a movable member (52) and a driving paddle (53). The movable member (52) is capable of moving between a locked position where the clutch (50a) is in the driving state and an unlocked position where the clutch (50a) is in the unlocked state. The driving paddle (53) transfers power with the wheels (30) by means of friction. When the clutch (50a) is in the driving state, the motor (40) drives the wheels (30) to rotate in a first direction; when the motor (40) stops
