The utility model discloses following beneficial effect has:
1. the arrangement requirement in a limited space is met:
when the swing space of the eccentric arm in the whole vehicle is limited, the functional requirement and the man-machine functional requirement of the lock can be still met, and the functions of unlocking and locking are ensured and comfortable man-machine experience is provided under the condition of insufficient layout space;
2. cost saving is realized:
the lock block does not need to be redeveloped or other components having spatial relation with the door lock do not need to be changed, and the design and development cost is reduced.
