Abstract

The invention discloses a door lock, a door assembly and a rail vehicle. The door lock comprises a lock main body, and the lock main body is provided with a handle, a spring bolt, a self-locking limiting piece and an unlocking handle. According to the door lock provided by the invention, the self-locking limiting piece is driven to act to lock the position of the handle through retraction of the spring bolt in the locking process, then the handle cannot be rotated relative to the lock main body, and thus self-locking of a vehicle door is achieved; and when the vehicle door needs to be opened, the unlocking handle can be operated to move the self-locking limiting piece to unlock the handle, and when the handle is rotated relative to the lock main body, the spring bolt is driven to retract to be separated from a lockhole. According to the door lock, the door assembly and the rail vehicle, self-locking is achieved when the vehicle door is closed, and the safety of the vehicle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a door lock, a door assembly and a rail vehicle. Background technique [0002] The space of the driver's cab of rail vehicles is limited, and the door on the car body usually adopts a door structure that takes up less space when opened. Currently, the door of the driver's cab usually adopts a hinged door structure, that is, the door body is installed in the driver's cab through hinges. on the door frame. [0003] Considering the special function of the driver's cab, the door of the driver's cab needs to have safety performance when it is closed in addition to taking up a small space. The current vehicle door lock usually needs to manually toggle the switch to lock the door lock after the car door is closed, and it often happens that the driver forgets to lock it manually. [0004] Therefore, providing a door lock with relatively high safety is a technical problem to be so...
