In one embodiment, the connecting portion 410 may include a rotating portion 411 and a driving portion 412, a rotating shaft may be fixedly disposed on the bottom plate 130, a hole matched with the rotating shaft is disposed on the rotating portion 411, so that the rotating portion 411 is rotatably disposed on the casing 100, the driving portion 412 is connected to the rotating portion 411, the first guiding portion 420 and the second guiding portion 430 are both connected to the rotating portion 411, and the first guiding portion 420 and the second guiding portion 430 are both located on a side of the rotating portion 411 away from the driving portion 412. As an embodiment, the included angle between the driving portion 412 and the first guiding portion 420 may be greater than 90 degrees and less than 180 degrees, so that the driving strap 400 may sweep a smaller area when rotating through the same angle, which is beneficial to saving space.

In other embodiments, a linear slide rail may be disposed on the bottom plate 130, and the rotating portion 411 is slidably disposed on the slide rail and can move along the slide rail, so as to drive the latch bolt assembly 200 to move in the process, and at this time, an included angle between the driving portion 412 and the first guiding portion 420 may be any angle.

Referring to fig. 5, 6 and 7, the driving assembly 300 is connected to the driving strap 400 by a connecting member 500, in one embodiment, the first guide portion 420 and the second guide portion 430 are disposed opposite to the base plate 130, meanwhile, both the first guide part 420 and the second guide part 430 can be provided with transmission holes, the transmission holes on the first guide part 420 and the transmission holes on the second guide part 430 form transmission hole groups, the orthographic projection of the first guide part 420 on the bottom plate 130 and the struggling projection of the second guide part 430 on the bottom plate 130 are approximately overlapped with each other, the transmission holes of the first guide part 420 and the transmission holes of the second guide part 430 are corresponding to each other, and in the orthographic projection of the first guide part 420 on the base plate 130 and the orthographic projection of the second guide part 430 on the base plate 130, the region where the transmission holes of the first guide part 420 are located and the region where the transmission holes of the second guide part 430 are located substantially coincide with each other. The follower 320 extends into the interval between the first guide part 420 and the second guide part 430, the connecting piece 500 is arranged in the driven hole 321 and the transmission hole group in a penetrating way, one end of the connecting piece 500 extends into the transmission hole of the first guide part 420, the other end of the connecting piece 500 extends into the transmission hole of the second guide part 430, and meanwhile, the transmission hole and the connecting piece 500 and the driven hole 321 and the connecting piece 500 are in clearance fit. When the driving strap 400 rotates around the rotation axis of the rotating portion 411, the first guiding portion 420 and the second guiding portion 430 rotate and push the connecting member 500 to move between the first position 3211 and the second position 3212 of the driven hole 321, so that the driving strap 400, the connecting member 500, and the driving assembly 300 can constitute a clutch assembly; in addition, because the connecting member 500 is in clearance fit with the driven hole 321, the connecting member 500 cannot drive the driven member 320 to rotate when the driven hole 321 moves. While the link 500 moves in the driven hole 321, the link 500 also moves in the transmission hole group.

In other embodiments, the plane of the first guide portion 420 and the second guide portion 430 may be perpendicular to the bottom plate 130, and the follower 320 may be bent and extend into the space between the first guide portion 420 and the second guide portion 430.

Specifically, when the connecting member 500 is located at the first position 3211 of the driven hole 321, the connecting member 500 is not located on the rotation path of the connecting shaft 330, and a user cannot act on the connecting member 500 when driving the connecting shaft 330 to rotate by rotating the door handle, so that the driven member 320 and the rotating member 310 cannot be driven to rotate, and at this time, the driving plate 400, the connecting member 500 and the driving assembly 300 form a clutch assembly in a separated state; when the connecting member 500 is located at the second position 3212 of the driven hole 321, the connecting member 500 is located on the rotation path of the connecting shaft member 330, and a user can act on the connecting member 500 and drive the connecting member 500 to move in the transmission hole group when driving the connecting shaft member 330 to rotate by the revolving door handle, so as to drive the driven member 320 and the rotating member 310 to rotate, and at this time, the transmission piece 400, the connecting member 500 and the transmission assembly 300 form a clutch assembly in a closed state. Through the arrangement, the safety of the door lock can be enhanced, when the door lock is not authorized by a user, the driving sheet 400, the connecting piece 500 and the driving assembly 300 are in a clutch state, and people except the user can not open the door lock by rotating the door handle.

For example, the transmission hole may be a kidney-shaped hole with an arc, and when the first guiding portion 420 and the second guiding portion 430 push the connecting member 500 to the second position 3212, the center of the arc of the transmission hole may coincide with the center of the rotation axis of the rotating member 310. When the connecting shaft 330 drives the connecting member 500 to rotate around the rotation center of the rotating member 310, the first guiding portion 420 and the second guiding portion 430 are not acted due to the clearance fit between the connecting member 500 and the kidney-shaped hole with the radian, so that the driving piece 400 located at the current position is prevented from being driven to rotate when the connecting shaft 330 drives the connecting member 500 to move in the kidney-shaped hole with the radian.

In other embodiments, the driving holes of the first guiding portion 420 and the second guiding portion 430 may be arranged as bar-shaped holes, and when the first guiding portion 420 and the second guiding portion 430 push the connecting member 500 to the second position 3212, the extending direction of the bar-shaped holes and the extending direction of the driven holes may be substantially perpendicular to each other.

In an embodiment, the driving assembly 600 may further include a motor, a speed reducer, and a moving element, a rotating shaft of the motor is connected to an input end of the speed reducer, an output end of the speed reducer is connected to the moving element, and the moving element drives the push block 610 to move along a direction parallel to an axis of the lock hole 120, wherein the push block 610 may be provided with a movable hole 611, the driving portion 412 may be provided with a protruding pillar 4121 to be in transmission fit with the push block 640, specifically, the protruding pillar 4121 is embedded in the movable hole 611, and the protruding pillar 4121 may translate in the movable hole 611. When receiving a working signal sent by a user, the motor rotates, and transmits power to the moving part through the speed reducer to drive the moving part to move horizontally, the moving part drives the push block 610 to move linearly, and at the moment, the convex column 4121 moves horizontally in the movable hole 611, so that the purpose that the push block 610 drives the driving part 412 to rotate is achieved. In other embodiments, the pushing block 610 is directly fixed on the driving portion 412, and the moving element drives the pushing block 610 to move the connecting element portion 410 along the extending direction of the sliding rail.

The working process of the lock body 10 provided by the embodiment of the utility model is as follows: when the lock body 10 is in the locked state, the latch bolt assembly 200 extends out of the lock hole 120 under the action of the reset assembly 230.

When the driving portion 412 does not drive the pushing block 610 to move so as to move the first guiding portion 420 and the second guiding portion 430, the connecting member 500 is located at the first position 3211 that is not within the range of the rotation path of the connecting shaft member 330, and when the connecting shaft member 330 rotates, the rotating member 310 cannot be rotated by driving the connecting member 500.
