A screw-driven control system includes a driving mechanism fixed in a cross beam, a guide locking piece and a limiting mechanism. The driving mechanism includes a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod, and a follow-up member fixed in the nut; the nut is mounted in the transmission frame, and the transmission frame is connected with a controlled object; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

Screw-driven control system

A door controller with an integrated data collection and transmission device, which comprises a motor driving module, a bus communication module, a vehicle door opening/closing control module, a parameter control module, and a data collection and transmission device. The data collection and transmission device is configured to receive and process four types of data collected by a motor driving data collection unit, a vehicle door opening/closing control data collection unit, an operation parameter collection unit, and a bus communication data collection unit, and transmit the four types of processed data to a background server.

A double sliding-plug door system includes a fixed frame, a sliding-plug rail arranged in the fixed frame, a cross beam, a driving mechanism, a linkage mechanism, a guide locking piece and a limiting mechanism. The driving mechanism has a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod and a follow-up member fixed in the nut; the nut mounted in the transmission frame, which itself is connected with an active sleeve assembly; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

A powerless helical locking mechanism for a door includes a screw with a variable lead angle connected with a power source, and a self-adaptive nut connected to the door. The helical slot of the screw is divided into a working segment with the helical lead angle greater than the friction angle, a closing segment with the helical lead angle smaller than the friction angle, and a transition segment between the closing and working segments. The power source actuates the screw to rotate bidirectionally.
