1. A combination lock, comprising:
a lock body; a shackle movably coupled at said lock body, wherein said shackle comprises a first leg and a second leg; a lock member received in said lock body, which comprises; a housing defining a second chamber, an upper end, and a lower end; an unlocking element pivotally provided between said upper end and said lower end; and a disc unit rotatably provided within said second receiving chamber, wherein said disc unit comprises a driving disc, wherein said driving disc has at least one driving opening and enables said unlocking element to fit into said driving opening such that when said driving opening is aligned with said unlocking element, said unlocking element is engaged with said driving opening of said driving disc to enable said driving disc to drive said unlocking element and said housing of said lock member to rotate; a first locking element movably coupled with said lock member and adapted to be driven by said lock member to move in a reciprocating manner between a shackle locking state and a shackle releasing state, wherein when said shackle is at said shackle locking state, said first locking element is engaged with said shackle, when said shackle is at said shackle unlocking state, said first locking element is driven to disengaged from said shackle; and an automatic unlocking device, wherein said automatic unlocking device comprises a laser scanner, a controller electrically connected with said laser scanner and a motor electrically connected with said controller for driving said disc unit to rotate so as to unlock said shackle in an automatic and keyless manner, wherein said first locking element comprises a first locking portion adapted to be engaged with said first leg of said shackle and a first driven portion extended from said first locking portion to said lock member and adapted to be driven by said lock member to move said first locking element in a reciprocating manner so as to hold said first leg at a position at said shackle unlocking state, and detach from said first leg at said shackle unlocking state, wherein when said lock member rotates, said first driven portion is driven by said lock member to move said first locking element in a reciprocating manner so as to hold said first leg in said lock body at said shackle unlocking state and drive said first locking portion to detach from said first leg to enable said first leg to separate from said lock body at said shackle unlocking state, wherein said lock body has an upper portion and a lower portion downwardly extended from said upper end, wherein said upper portion has a first receiving chamber for receiving said lock member therein, wherein said lock member comprises a housing for driving said first locking element to move to release said first leg of said shackle from said lock body. |
