Novel automobile door lock with space compliant double-branch-chain structure

The invention belongs to the field of automobile engineering, and discloses a novel automobile door lock with a space compliant double-branch-chain structure. Compliant double-branch-chains in the automobile door lock comprise an opening branch chain and a safety branch chain; the opening branch chain and the safety branch chain are both constructed by a spatial mechanism, a torsional spring is installed in the mechanism to form the compliant branch chains, and the compliant double-branch-chains capable of adapting to various working conditions are constructed; a duplicate gear is driven by a single motor, so that the opening branch chain and the safety branch chain act in a coordinated manner according to an expected time sequence to realize electric opening and electric safety of the door lock respectively; in the opening branch chain, the two branch chains in the door lock system act in sequence according to a preset sequence through incomplete gear transmission, and reset of the two branch chains and part
