The above one or more technical solutions have the following beneficial effects:
only under the lock state is relieved to the lock, the switch group can open passenger's door through the controller, prevents that passenger's door unblock back because the power that the door pump cylinder exists for passenger's door is opened suddenly and is caused the potential safety hazard.
Drawings
The accompanying drawings, which form a part of the specification, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention without unduly limiting the scope of the invention.
Fig. 1 is a schematic diagram of an overall structure provided by one or more embodiments of the present invention;
in the figure: 1. a door lock; 2. a lock pin; 3. a lock-up signal sensor; 4. a remote switch; 5. A rocker switch; 6. a controller; 7. an electromagnetic directional valve; 8. a door pump cylinder; 9. and (4) a gas source.
Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background of the invention, in a passenger car without a passenger door safety device, when an operator performs a power opening operation using a remote control or other means after a passenger door is locked, a door pump cylinder pushes the passenger door to attempt to perform a door opening operation, and due to the existence of a mechanical door lock, the movement of the passenger door is restricted, so that the passenger door cannot be opened.
At this time, if the operator directly opens the passenger door lock, since the exhaust end gas of the door pump cylinder is exhausted, the passenger door is locked and not opened, but still bears the pushing force required by the door opening action, so that once the passenger door is unlocked, the passenger door can be rapidly opened under the pushing of the door pump cylinder, the generated instant impact force can generate physical collision to the passenger door mechanism itself to cause damage, and meanwhile, the passenger door mechanism and the passengers nearby have great potential safety hazards.
Example 1:
as shown in figure 1, the passenger car door safety device comprises a controller 6 respectively connected with a switch circuit, a door lock 1 and a door pump cylinder 8, wherein the door lock 1 is connected with the controller 6 through a locking signal sensor 3, the door pump cylinder 8 is connected with the controller 6 through an electromagnetic directional valve 7, and the door pump cylinder 8 is supplied with gas through a gas source 9.
The switch circuit includes a switch group, such as a remote switch 4 or a rocker switch 5, which is connected to the controller 6, respectively, and issues an instruction to the controller 6 to open/close the passenger door.
The door lock 1 is provided with a lock pin 2, and in a locked state of a passenger door, the lock pin 2 triggers the locking signal sensor 3 to act, and locked information is transmitted to the controller 6.
The controller 6 is configured to: receiving locking state information sent by a locking signal sensor 3, and shielding a power door opening signal sent by a switch group;
at this time, when the operator uses the switch group to perform the door opening operation in a power manner, the door pump cylinder 8 does not perform the door opening operation (since the passenger door is locked, the door lock 1 is in the locked state, and the passenger door is ineffective in performing the door opening operation in the locked state and is not in compliance with the operation specifications).
After the door lock 1 is unlocked, the lock pin 2 does not trigger the locking signal sensor 3 to operate, and information of the unlocked state is transmitted to the controller 6.
The controller 6 is further configured to: and the locking releasing state information sent by the locking signal sensor 3 is received, and the door pump cylinder 8 normally executes a door opening action command sent by the switch group, so that potential safety hazards or mechanism damage caused by rapid movement of a passenger door under misoperation of an operator is avoided.
The utility model provides a passenger train, has installed above-mentioned safety device on passenger's door, ensures to prevent that passenger's door from opening suddenly because of the unblock when passenger's door is locked can't open passenger's door, avoids the potential safety hazard that passenger's door rapid movement produced.
The introduction of the passenger car door safety device is characterized in that when a passenger door of a passenger car is locked, a lock pin 2 of a door lock 1 triggers a locking signal sensor 3, a controller 6 shields a door opening instruction sent by a remote control switch group, and only when the door lock 1 is in a unlocking state, the switch group can open the passenger door by means of the controller 6, so that the potential safety hazard caused by sudden opening of the passenger door due to the power of a door pump cylinder after the passenger door is unlocked is prevented.
Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
