When the top block 800 swings in a direction approaching to the second latch 500, the torsion spring 820 deforms and stores energy, and when the transmission mechanism 700 drives the top block 800 to swing in a direction away from the second latch 500, the torsion spring 820 resets and drives the top block 800 to reset quickly.
It will be appreciated that the transmission mechanism 700 includes a rotating shaft 710 rotatably connected to the housing 100, a first turbine 720 provided at one end of the rotating shaft 710, and a tooth surface 730 provided at one end of the top block 800 or the hinge shaft 810, the tooth surface 730 being a partial structure of a gear, and the first turbine 720 and the tooth surface 730 being engaged with each other. The cooperation of the first turbine 720 and the tooth surface 730 can convert the rotation motion of the rotation shaft 710 into the rotation of the hinge shaft 810 and the swing of the top block 800, thereby realizing the axial change of the rotation shaft.
Further, the transmission mechanism 700 further includes a second turbine 740 disposed on an output end of the motor 600 and a gear 750 disposed on another end of the rotating shaft 710, where the second turbine 740 is in transmission connection with the output end of the motor 600. The second turbine 740 is in a state of being sleeved on the output shaft of the motor 600.
The rotation axes of the motor 600, the second turbine 740, the gear 750, the rotation shaft 710 and the first turbine 720 are in the same plane, the motor 600 and the rotation shaft 710 are perpendicular to each other, and the hinge shaft 810 and the rotation shaft 710 are perpendicular to each other. The motor 600 and the transmission mechanism 700 are compact in structure, high in reliability and small in occupied space.
Referring to fig. 9, reference is made to the direction indicated by the arrow in the figure. In a correctly installed state of the door lock clutch device, the dial block 200 is provided with a protrusion 230, and the protrusion 230 faces downward. Left fool-proof limiting blocks 170 and right fool-proof limiting blocks 180 are hinged to the left side and the right side of the bottom of the inner cavity of the shell 100 respectively. The left fool-proof limiting block 170 and the right fool-proof limiting block 180 can swing on a vertical plane, under the action of gravity, the free ends of the left fool-proof limiting block 170 and the right fool-proof limiting block 180 are all abutted against the bottom of the shell 100, that is, the free ends of the left fool-proof limiting block 170 and the right fool-proof limiting block 180 are far away from the protruding portion 230, at this time, the shifting block 200 is rotated, when the protruding portion 230 rotates along with the shifting block 200, the protruding portion 230 does not interfere with the left fool-proof limiting block 170 and the right fool-proof limiting block 180, and the handle square 220 and the shifting block 200 can normally rotate. When the door lock clutch device is installed upside down, under the action of gravity, the free ends of the left foolproof limiting block 170 and the right foolproof limiting block 180 swing towards the direction of the housing 100, that is, the free ends of the left foolproof limiting block 170 and the right foolproof limiting block 180 are both close to the protruding portion 230 and are located on the movement track of the protruding portion 230, the free ends of the left foolproof limiting block 170 and the right foolproof limiting block 180 will interfere with the protruding portion 230, thereby limiting the positive rotation of the protruding portion 230 and the shifting block 200, and at this time, the handle lever 220 cannot be normally rotated, so as to remind an installer that the door lock clutch device is installed upside down.
