Door mount mechanism for a smart lock system

A door mount mechanism for a smart lock system, said door mount mechanism being adapted to be mounted onto a door for rotating a thumb turn of a door lock which is mounted on the door, said door mount mechanism comprising:

• a casing having a door-mounting end that is adapted for abutting against the door, and defining a receiving space that is adapted for receiving the door lock, and that has an opening at said door-mounting end and adapted for extension of the door lock therethrough;
• a rotatable component coupled rotatably to said casing;
• and
• an intermediate coupling including
• a first coupling segment that is connected co-rotatably to said rotatable component, and
• a second coupling segment that is connected co-rotatably to said first coupling segment, that is linearly movable relative to said first coupling segment in directions perpendicular to an axis about which the thumb turn rotates, and that is adapted for driving rotation of the thumb turn of the door lock such that the thumb turn is co-rotatable with said rotatable component,
• wherein said first coupling segment of said intermediate coupling has two subsegments connected to a periphery of said rotatable component, each of said subsegments having opposite first and second ends, said first ends of said subsegments being aligned with each other in a first direction, said second ends of said subsegments being aligned with each other in the first direction;
• and
• said second coupling segment of said intermediate coupling has a main subsegment adapted for surrounding the thumb turn of the door lock, and four coupling subsegments, two of said coupling subsegments being connected to an end of said main subsegment and connected slidably and respectively to said first and second ends of one of said subsegments of said first coupling segment, the other two of said coupling subsegments being connected to an opposite end of said main subsegment and connected slidably and respectively to said first and second ends of the other one of said subsegments of said first coupling segment, said main subsegment having a width in a second direction perpendicular to the first direction and adapted to be larger than that of the thumb turn.

A smart lock system comprising:

• a control circuit for receiving commands from a user device;
• and
• a mount mechanism adapted to be mounted onto a subject for rotating a knob of a switch mechanism which is mounted on the subject, and including:
• a casing that has a mounting end adapted for abutting against the subject, and that defines a receiving space adapted for receiving the switch mechanism, and having an opening at said mounting end that is adapted for extension of the switch mechanism therethrough,
• a rotatable component that is coupled rotatably to said casing,
• an intermediate coupling that includes
• a first coupling segment connected co-rotatably to said rotatable component, and
• a second coupling segment connected co-rotatably to said first coupling segment, being linearly movable relative to said first coupling segment in a first direction perpendicular to an axis about which the knob rotates and a second direction perpendicular to the axis and perpendicular to the first direction, and adapted for driving rotation of the knob of the switch mechanism such that the knob is co-rotatable with said rotatable component, and
• an actuating unit that is connected to said control circuit, said actuating unit being activated by signals that are received from said control circuit, and being adapted for rotating the knob via said intermediate coupling.
