The invention discloses an elevator door motor mechanism capable of preventing hands from being pinched. The elevator door motor mechanism comprises a driving box, a driving mechanism, an extrusion mechanism and a maintenance mechanism. When an elevator door needs to be opened and closed, a motor works, when the motor works, the motor drives a bidirectional threaded rod to rotate, when the bidirectional threaded rod rotates, a ball nut pair on the bidirectional threaded rod rotates, when the ball nut pair rotates, the ball nut pair moves on the bidirectional threaded rod, and when the elevator door moves towards the middle, the motor drives the bidirectional threaded rod to rotate. The rubber protection sleeves on the two sides mutually abut against each other and extrude each other, due to the fact that the rubber protection sleeves are made of rubber, even if the hand is clamped, the first springs are compressed, the rubber protection sleeves move into the protection grooves, injury caused by hand clamping is reduced, meanwhile, when the infrared sensors arranged in the rubber protection sleeves sense that the hand is clamped, the motors are controlled to rotate reversely, and the hand is clamped. And the ball nut pair drives the elevator door to move towards the outer side through the moving block, the elevator door is opened, and subsequent damage is avoided.

    本发明公开了一种防夹手的电梯门机机构,包括驱动箱、驱动机构、挤压机构和维护机构。本发明,在电梯需要进行开关门时,电机工作,在电机工作时,使电机带动双向螺纹杆旋转,在双向螺纹杆旋转时,使双向螺纹杆上的滚珠螺母副转动,在滚珠螺母副转动时,使滚珠螺母副在双向螺纹杆上移动,此时电梯门向中部移动时,两侧橡胶防护套相互对其并挤压,由于橡胶防护套材质为橡胶,即使手部被夹住,此时弹簧一被压缩,使橡胶防护套移动至防护槽内,降低了夹手时的伤害,同时橡胶防护套内设置的红外线传感器感应到手部被夹住时,控制电机反转,使滚珠螺母副通过移动块带动电梯门向外侧移动,将电梯门打开,避免后续造成伤害。
