Door lock device, door, and mobile vehicle

A door, wherein the door comprises a door lock device;

• wherein the door lock device comprises a housing, a lock tongue, a lock bolt, a clutch assembly, and a handle assembly, wherein the lock tongue, lock bolt, and clutch assembly are arranged within the housing, and the handle assembly is rotatably connected to the housing;
• the lock tongue has an extended state and a retracted state relative to the housing, and when the handle assembly is rotated, the lock tongue is driven to switch from the extended state to the retracted state;
• and
• the lock bolt has an extended state and a retracted state relative to the housing, and when the lock tongue switches from the extended state to the retracted state, the lock tongue drives the lock bolt to retract relative to the housing;
• the clutch assembly comprises a lock tongue clutch component and a lock bolt clutch component, and the clutch assembly has a first state and a second state;
• when the clutch assembly is in the first state, the lock tongue clutch component is in an engaged state relative to the lock tongue, and the lock bolt clutch component is in a disengaged state relative to the lock bolt;
• if both the lock tongue and the lock bolt are in the extended state, the lock tongue clutch component is configured to limit the lock tongue from retracting;
• when the clutch assembly is in the second state, the lock tongue clutch component is in the disengaged state relative to the lock tongue, and the lock bolt clutch component is in the engaged state relative to the lock bolt;
• if the lock bolt is in the retracted state, the lock bolt clutch component is configured to limit the lock bolt from extending, and the lock tongue is configured to extend or retract relative to the housing;
• the clutch assembly further comprises a transmission mechanism;
• the transmission mechanism comprises a swing arm, with a first end of the swing arm rotatably connected to the housing, and a second end movably connected to the lock tongue clutch component and/or the lock bolt clutch component;
• wherein the lock tongue clutch component is defined with a guiding groove, and the second end is inserted into the guiding groove;
• when the swing arm rotates in a first direction or a second direction, the second end moves along the guiding groove relative to the lock tongue clutch component, causing the lock tongue clutch component to switch between the disengaged state and the engaged state.
