Guiding device of electronically controlled electric vehicle door

Abstract

The invention provides a guiding device of an electronically controlled electric vehicle door. The system comprises vehicle door systems (1) and a door head mechanism (7), wherein each vehicle door system (1) comprises left and right door leaves (1-1) and a shifting fork (1-2). The guiding device is characterized in that a door control unit (6) gives an instruction, then a motor drives variable diameter screws to rotate, and variable diameter nuts drive the shifting fork and the door leaves to carry out linear motion along the axis direction of the screws, thus quick opening and closing of the vehicle door are achieved through screwing of a minor-diameter nut-screw pair, and quick self-locking of the vehicle door is achieved through screwing of a major-diameter nut-screw pair. According to the guiding device, a locking device and a transmission device are combined into a whole; the minor-diameter part achieves quick opening and closing of the vehicle door; the closing speed is improved to 1.5-4.5s; spherical guide wheels and guide rails form point contact; when the guide wheels roll, the frictional resistance is low and the frictional heat is still maintained at the original level, so that noises can not be added; the screw-nut screw pairs achieve self-lubricating and the operating states are ensured without oiling, thus reducing the maintenance cost; and a more advanced, reasonable, safe and quick vehicle door system is formed.

Description

technical field [0001] The invention relates to a transmission, guide and mechanical locking device of an electronically controlled electric door of a rail transit vehicle, in particular to a guide device for an electrically controlled electric door with low friction and heat reduction. Background technique [0002] Electric control electric doors for rail vehicles are widely used in railways and urban rail trains. It is mainly composed of door leaf, driving mechanism, transmission device, guiding device, locking device, door control unit (DCU) and door head mechanism. The driving mechanism is the power source, which drives the transmission device, turns the rotary motion into a linear motion, and transmits it to the door leaf to realize the opening and closing of the door leaf. The guide device defines the running track of the door leaf. After the door is closed, the locking device must ensure that the door cannot be opened when the motor stops and no torque is applied to...
