MOTOR CAM OPERATING MECHANISM AND TRANSMISSION MECHANISM THEREOF

摘要

A transmission mechanism of a motor cam operating mechanism is in coordination with a cam (106) driven by a motor and is arranged on a side of the cam. The transmission mechanism comprises: a link lever (103), a sector lever (105), a spring mechanism (112), and a thrust shaft pin (111). An outer end of the link lever (103) is provided with a pin hole (132); an inner end of the link lever (103) has a chute (151); the cam shaft pin (113) penetrates the chute (151) and is fastened on the cam (106); when the cam (106) rotates, the cam shaft pin (113) moves in the chute (151); the cam (106) drives, through the cam shaft pin (113), the link lever (103) to move; a roller (104) is installed between the pin hole (132) and the chute (151). The sector lever (105) is connected to a spindle (107), and the sector lever (105) is provided with a first chute (151). The top of the spring mechanism (112) is provided with a hole. The thrust shaft pin (111) penetrates second chutes (501) on two side plates (115), the first chute (151) on the sector lever (105), the hole on the top of the spring mechanism (112), and the pin hole (132) on the outer end of the link lever (103); the thrust shaft pin (111) makes linkage of the link lever (103), the sector lever (105) and the spring mechanism (112). The thrust shaft pin (111) compresses the spring mechanism (112) to store energy, and in an energy releasing phase of the spring mechanism (112), the thrust shaft pin (111) drives the sector lever (105) to rotate, and drives, through the spindle, a contact to move. The transmission mechanism has a simple structure and is reliable in transmission.
