Abstract

The invention relates to a passive locking device for a vehicle door. The passive locking device comprises a connecting frame moving left and right relative to a door frame, a door carrying frame forconnecting the vehicle door, a lock pin fixed on the door frame, an unlocking block connected with the connecting frame and the door carrying frame respectively, a locking part rotationally connectedto the door carrying frame, and a reset part arranged on the door carrying frame, wherein one end of the locking part is provided with a driving part allowing the unlocking block to push in the direction of extending upward of the door opening side of the locking part, the other end of the locking part is provided with a lock hook capable of achieved locking and unlocking with the lock pin in thedirection of extending downward, and the reset part can drive the locking part to reset so as to achieve the locking state of the lock hook and the lock pin. The passive locking device for the vehicledoor has simple structure and good detachability, and is easy to maintain without setting an unlocking power source additionally.

Description

Technical field[0001]The present invention relates to the technical field of rail transit, in particular to a passive locking device for vehicle doors.Background technique[0002]With the development of urban rail transit systems, there are higher requirements for the functionality, reliability, and maintainability of screen door system components. As a key component of the screen door system, the safety and reliability of the locking device is directly related to the operational safety. According to statistics, the current locking failures of the screen door system account for 30% to 60% of the total system failures, and the failure rate of the locking device can better illustrate the importance of selecting a reasonable locking mechanism. Therefore, a reasonably designed locking mechanism can greatly reduce the failure rate of the screen door system, thereby ensuring the punctuality and safe operation of the vehicle.[0003]In the rail transit screen door system, the LS passive lockin...
