The present disclosure discloses a rail vehicle. The rail vehicle includes: a plurality of bogies, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; at least one bogie is disposed on one of the bottom of each of the compartments and a hinging position of neighboring compartments; and in the length direction of the rail, a surface that is of a compartment at at least one end of the vehicle body and that faces away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, reduction in costs, reduction in occupied space and the weight borne by the rail, and improvement in stability, and is high in stability of supporting the vehicle body and large in passenger capacity.

The present disclosure provides a bogie, a rail vehicle having same, and a rail transport system. The bogie includes: a bogie frame, where the bogie frame has a straddle recess straddling a rail; a first running wheel and a second running wheel, where the first running wheel and the second running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart; a third running wheel and a fourth running wheel, where the third running wheel and the fourth running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart; a driving device, where the driving device is located between the first running wheel and the second running wheel, and the first running wheel and the second running wheel are driven by the driving device; and/or the driving device is located between the third running wheel and the fourth running wheel, and the third running wheel and the fourth running wheel are driven by the driving device. The bogie according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, and has advantages such as high space utilization, high stability, and strong weight bearing capability.

The present disclosure discloses a rail transport system. The rail transport system includes: a rail, where the rail is provided with an escape passage; and a rail vehicle, where the rail vehicle includes a vehicle body and a plurality of bogies, the plurality of bogies respectively movably straddles the rail, and the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail; and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail, the plurality of compartments forms at least one compartment group, the compartment group includes three compartments hinged sequentially, and the bottom of each of only compartments that are located at two ends of the compartment group and that are of the three compartments is connected to the bogie. The rail transport system according to this embodiment of the present disclosure has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, high stability, and flexible steering.

The manual release mechanism described herein enables a passenger to attempt to manually open the door but delays opening until the vehicle is no longer moving. A motion transfer device moves to an unlocking position of the door lock only when the manual release mechanism is activated to release store energy in a mechanical energy storage device and an electromechanical device is de-energized to release the motion transfer device.

A safety system for an enclosure includes a door. The safety system includes a triggering circuit configured to generate a trigger signal based on an event associated with the enclosure. The safety system further includes a fastener operably coupled to the triggering circuit, wherein the fastener is adapted to maintain the door of the enclosure in a locked condition and disengage itself to unlock the door of the enclosure in response to the triggering signal.

A releasable seal assembly is provided that may include a first extension profile and a second extension profile extending from a core. The first extension profile may include a first exit panel side wing resiliently hinged to the core, and a first host panel side wing extending from the core. The first exit panel side wing and the first host panel side wing may define a first key cavity, and the first exit panel side wing has a first arcuate surface that may define a first retention tongue recess of the first key cavity. Additionally, the first host panel side wing has a second arcuate surface that defines a second retention tongue recess of the first key cavity. The first exit panel side wing may include a first exit panel side wing tongue configured to be received within the second retention tongue recess.

The purpose of this plan is to reduce the damages in intercity train crash cases to the passengers. Berth sleeper airbags are designed to protect the passenger's head and body while the passenger is asleep in the berth sleeper, which inflates in the event of a rollover accident.

The present disclosure discloses a rail transport system. The rail transport system includes: a rail, where the rail is provided with an escape passage; and a rail vehicle, where the rail vehicle includes a vehicle body and a plurality of bogies, the plurality of bogies respectively movably straddles the rail, and the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail; and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail. The rail transport system according to this embodiment of the present disclosure has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, high stability, and large passenger capacity.
