Definitions

  • Railcars in public transportation system have doors with motors that automatically open and close. For example, passenger railcars open the door when the railcar arrives at a station so the passengers can depart the railcar. The doors close after the passengers waiting at the station board the railcars.
  • a separate locking device holds the doors closed. When the doors are opened, the locking device unlocks the door before the electric motor opens the door.
  • the locking device is typically electrically actuated. That is, an electric current moves an armature in the locking device to move a bolt or a latch into or out of an aperture or a groove.
  • the aperture or groove can be in the door or in a carriage attached to the door.
  • the locking device is actuated when a sensor detects when the door reaches the closed position. Alternatively, the electrical signal can be sent to the locking actuator to unlock the door.
  • a bias force such as a spring bias force, can press the bolt or latch into the aperture or groove to lock the doors.
  • One failure mode is where the locking actuator is non- functional but the motor is still able to move the door. Since the locking actuator has failed, the doors remain locked even though the motor is attempting to move the door. This failure mode can result in the doors remaining closed and the motor drawing excessive amounts of current.
  • Another failure mode occurs when the motor is unable to open the door but the locking actuator is operational. In this failure mode, the locking actuator unlocks the doors. As a result, the doors can be manually opened rather than opened through designed means such as the motor or an emergency door release. Once opened, the motor cannot close the doors. If the sensor does not sense that the doors are not closed, the train could leave the station with the doors still open.
  • the motor and the locking actuator also have independent failure rates and associated costs. Therefore, eliminating the locking actuator eliminates failure modes resulting in unsafe conditions and reduces the overall probability of component failure and associated costs.
  • the door actuating and locking mechanism comprises an actuator with a actuator shaft and an actuating length, a door carriage adapted to be coupled to a door on the vehicle, the door carriage is movably coupled to the actuator shaft and slidably coupled to the actuator such that the actuator shaft rotates to move the door carriage along the actuating length.

  • the motor body 152 rotates the lever 160 to the unlocked position UL. During this rotation the lever 160 presses against the cam 142a coupled to the locking bolt 142. The locking bolt 142 moves away from the locking arm 172. This movement withdraws the locking bolt 142 from the locking arm 172. In particular, the locking bolt 142 is withdrawn from the aperture 172a on the locking arm 172. After the locking bolt 142 is withdrawn from the locking arm 172, the motor body 152 can rotate to the unlocked position UL and stop. The motor 150 can then open the doors 14.
  • the motor 150 moves the door 14 to the open position by rotating the rotatable shaft 154. As shown, when the lever 160 reaches the unlocked position UL, the motor body 152 is prevented from rotating by the locking device 140. The motor 150 then rotates the actuator shaft 122 in the actuator 120. The rotating actuator shaft 122 in the actuator 120 moves the movable platform 128 to move the door carriage 130 via the carriage buffer 170. The door carriage 130 can therefore move from the closed position shown in FIG. 2b to the open position (proximate the open position stop 112a).
  • the door carriage 130 stops when it reaches the open position.
  • the door carriage 130 may stop because the movable platform 128 stopped moving along the actuating length X.
  • the movable platform 128 can stop due to, for example, the door carriage 130 an open position sensor sensing the door carriage 130 position or the motor 150 turning a predetermined number of steps. Alternatively, the door carriage 130 can stop moving due to reaching the open position stop 112a.
  • the door actuating and locking mechanism 100 can also move the door 14 to the closed position and lock the door 14 with the rotation of the motor body 152.
  • the motor 150 can begin rotating the actuator shaft 122 when the door carriage 130 is in the open position.
  • the motor body 152 can rotate to the locked position L. This will rotate the lever 160 away from the cam 142a on the locking bolt 142.
  • the return spring 144 presses the locking bolt 142 out of the locking device 140.
  • the motor 150 continues to rotate the actuator shaft 122 to move the door carriage 130 towards the closed position.
  • the locking arm 172 slides over and presses the locking bolt 142 into the locking device 140 until the locking bolt 142 aligns with the aperture 172a.
  • the locking bolt 142 and the aperture are aligned, the locking bolt 142 is pressed into the aperture 172a by the return spring 144.
  • the locking arm 172 also actuates the door lock sensor 114 by pressing against the lock sensor lever 114a.
  • the embodiments described above provide a door actuating and locking mechanism 100.
  • the door actuating and locking mechanism 100 eliminates the need for a locking device that is operates separately from the motor 150.
  • the locking device 140 is actuated only when the motor 150 is applying a torque to move the door 14. Therefore, the locking device 140 cannot be actuated, for example, by an erroneous signal to a separate door locking actuator found in prior art door actuating and locking mechanisms.
  • the door 14 will also not be unlocked unless the motor 150 is applying a torque to the actuator shaft 122. The door 14 will therefore remain locked until the motor 150 is able to move the doors 14.
