Generally, the lock body can be used as a lock for locking a door to play a role in theft prevention, and can be used as a passage lock when people need to frequently go in and out or rescue, escape and the like.

For facilitate the use, prevent under the emergency that the door lock converts the functional failure of passageway lock into, the clutching mechanism of this embodiment includes mechanical clutching mechanism 700 and automatically controlled clutching mechanism 900, and mechanical clutching mechanism 700 and automatically controlled clutching mechanism 900 set up respectively before between handle 300 and transmission shaft 500 to be used for controlling before handle 300 to switch under free state and normally open state.

The electronic control clutch mechanism 900 can be connected with the mobile phone Bluetooth, and when the mobile phone APP sends out a control signal, the response of the electronic control clutch mechanism 900 can be combined or disconnected in response to the control signal. Of course, in other embodiments, a control panel may be disposed on the front panel 100, and the control panel is electrically connected to the electronically controlled clutch mechanism 900, and sends a control signal to the electronically controlled clutch mechanism 900 through the control panel.

The mechanical clutch mechanism 700 is controlled by an operation key 800, and in order to secure the anti-theft performance as a door lock, the operation key 800 is provided on the rear panel 200 inside the door, and a person inside the door can operate the operation key 800 to engage or disengage the mechanical clutch mechanism 700.

When at least one of the mechanical clutch mechanism 700 and the electrically controlled clutch mechanism 900 is engaged, the front handle 300 is in a normally open state; when both the mechanical clutch mechanism 700 and the electronic control clutch mechanism 900 are off, the front handle 300 is in the free state.

For the sake of understanding, the control modes of the electrically controlled clutch mechanism 900 and the mechanical clutch mechanism 700 are described separately below, and those skilled in the art will understand the use mode of controlling both mechanisms simultaneously.

As shown in fig. 3, 4 and 5, the electrically controlled clutch mechanism 900 includes a linear driving module formed by a motor 910, a motor shaft 920 and a locking top member 930, and a second clutch member 940 and a transmission shaft connecting member 720, wherein the second clutch member 940 is connected to the locking top member 930.

To reduce the size of the lock body and to facilitate the installation of the lock body, the linear driving module and the second clutch member 940 are integrated in the rotary shaft 310 of the front handle. Therefore, the linear driving module and the second clutch 940 do not occupy extra space, the space occupation is reduced, and the structure of the lock body is more compact. When the electric control clutch mechanism 900 is installed, no additional installation step is needed, and only the front handle 300, the lock case and the internal components thereof need to be normally installed, and the transmission shaft connecting piece 720 is fixed on the transmission shaft 500, so that the electric control clutch mechanism 900 can be installed.

The transmission shaft connecting part 720 is provided with a third clutch 950, and the linear driving module drives the second clutch 940 to move along the rotating shaft 310 of the front handle to approach or depart from the transmission shaft connecting part 720, so that the second clutch 940 is engaged with or disengaged from the third clutch 950.

A key groove is formed on the second clutch 940, and a square key is formed on the third clutch 950. The second clutch key is close to the third clutch member 950 so that the key groove is engaged with the square key to transmit rotation; the second clutch 940 and the third clutch 950 are moved away to separate the key groove from the square key.

When the second clutch 940 is matched with the third clutch 950, the electrically controlled clutch mechanism 900 is combined, the front handle 300 is in a normally open state, the front handle 300 is rotated to drive the second clutch 940, and the transmission shaft 500 is driven to rotate through the transmission shaft connecting part 720.

When the second clutch 940 and the third clutch 950 are separated, the electrically controlled clutch mechanism 900 is turned off, the front handle 300 is in a free state, and when the front handle 300 is rotated, the front handle 300 idles, and the transmission shaft connecting part 720 and the transmission shaft 500 do not rotate.

Third clutch 950 may be removably mounted to drive shaft coupling 720. May be integrally formed with drive shaft coupling member 720, i.e., third clutch 950 is formed on drive shaft coupling member 720 and second clutch 940 is directly engaged with drive shaft coupling member 720.

The pivot 310 of preceding handle not only provides the accommodation space with installation straight line drive module and second separation and reunion piece 940, can also play the effect of direction, under the condition that does not additionally increase guide structure, improves the mobility stability. For example, a square passage is formed inside the rotation shaft 310 of the front handle, and the locking top 930 and the second clutch 940 are provided with external shapes to be engaged with the square passage to restrict circumferential rotation of the locking top 930 and the second clutch 940 to maintain stable axial movement thereof, and to ensure engagement of the second clutch 940 with the third clutch 950.

The engagement of the motor shaft 920 and the locking top 930 may be a threaded engagement, forming a lead screw nut-like structure.

The matching of the motor rotating shaft 920 and the locking top piece 930 can also be as follows: the motor rotating shaft 920 is sleeved with a spring, supporting legs at two ends of the spring are fixed on the motor rotating shaft 920, the motor rotating shaft 920 is sleeved with a locking top piece 930, a guide rod extending towards the motor rotating shaft 920 is formed inside the locking top piece 930, and the guide rod is matched in a track of the spring. When the motor shaft 920 rotates, the guide bar moves along the track of the spring, and the locking top 930 is driven to extend or retract by the elastic force of the spring.

In this manner, when the second clutch 940 deflects or otherwise becomes obstructed from engaging the third clutch 950, the motor 910 may be rotated according to a predetermined program and the guide rod moves along the track of the spring to compress the spring for charging. When the second clutch 940 is returned to its original position, for example, when the front handle 300 is rotated to return the second clutch 940 to its original position, or when an obstacle is eliminated by other means, the spring-released energy storage drives the second clutch 940 to extend through the locking top 930, so that the second clutch 940 can be successfully combined with the third clutch 950, and the electrically controlled clutch mechanism 900 is ensured to be combined.

On the contrary, when the second clutch member 940 can not retract into the rotating shaft 310 of the front handle due to a fault, the motor 910 rotates according to a preset program, the guide rod moves along the track of the spring to compress the spring for energy storage, and after the fault is relieved, the spring releases the energy storage to drive the second clutch member 940 to retract through the locking top member 930, so that the second clutch member 940 can successfully separate and couple with the third clutch member 950, and the electronic control clutch mechanism 900 is ensured to be disconnected.

Alternatively, in other embodiments, the linear driving module may also adopt other mechanisms such as the linear motor 910, a micro-cylinder, a micro-electric magnetic push rod, etc., as long as the second clutch 940 can be driven to approach or move away from the transmission shaft connecting member 720.

Alternatively, in other embodiments, the second clutch 940 may be disposed outside the rotating shaft 310 of the front handle, and the third clutch 950 may be disposed on the transmission shaft connecting member 720 at a position corresponding to the second clutch 940.

In addition, the electronic device sometimes depends on external devices, such as a mobile phone signal, the opening speed of the mobile phone APP, the bluetooth connection state, and the like, and if the electrically controlled clutch mechanism 900 cannot respond quickly, inconvenience may be brought to the user, and even more serious risks may be caused in emergency situations, such as emergency escape or quick rescue of indoor personnel.

The mechanical clutch mechanism 700 is matched with the electronic control clutch mechanism 900, and the defect that the electronic control clutch mechanism 900 depends on external equipment can be overcome.

When the handle steering member 710 drives the transmission shaft connecting member 720 to rotate through the first clutch member 740, in order to prevent the first clutch member 740 from losing the stopper 730 and being blocked from coming out of the accommodating hole 721, a first limiting member 750 is disposed on a rotation path of one end of the accommodating hole 721 far away from the handle steering member 710.

Referring to fig. 7 again, the front handle 300 is pressed down to unlock, so as to drive the handle steering member 710, the first clutch member 740 and the transmission shaft connecting member 720 to rotate clockwise, and the first limiting member 750 is disposed on the clockwise rotation path at the end of the accommodating hole 721.

The limiting surface of the first limiting member 750 is an arc surface. In order to save materials, the first position limiting members 750 are arc-shaped ribs.

In general, the front handle 300 cannot be lifted, but the front handle 300 may be loosened to be lifted slightly after a long time use, or some front handles 300 themselves have a function of being lifted and unlocked.

Lifting up the front handle 300 will drive the handle to turn the piece 710 counterclockwise. The principle of lifting the lock on the front handle 300 is the same as the principle of pushing the lock on the front handle 300, and the description is omitted here.

When the handle steering member 710 drives the transmission shaft connecting member 720 to rotate reversely through the first clutch member 740, in order to prevent the first clutch member 740 from losing the stopper 730 to stop and falling out of the accommodating hole 721, a second limiting member 760 is disposed on a reverse rotation path of one end of the accommodating hole 721 away from the handle steering member 710.

The first limiting member 750 and the second limiting member 760 are spaced apart from each other to form a through opening 770 therebetween, the receiving hole 721 is aligned with the through opening 770 in an initial state, and when the second recess 731 is aligned with the receiving hole 721, the first clutch 740 can enter the second recess 731 through the through opening 770.

The second limiting member 760 may also be configured as an arc-shaped surface. In order to save materials, the arc-shaped ribs can also be arranged.

Under the action of the first limiting member 750 and the second limiting member 760, the first clutch member 740 can move in the accommodating hole 721 to enter and exit the first groove 711 or the second groove 731, and when the handle steering member 710 is combined with the transmission shaft connecting member 720 through the first clutch member 740, no matter whether the front handle 300 drives the handle steering member 710 to rotate forward or backward, there is no risk that the first clutch member 740 is disengaged from the accommodating hole 721, and it is ensured that the mechanical clutch mechanism 700 is effectively combined.

For example:

the accommodation hole 721 is a horizontal hole provided on the drive shaft connection member 720 in the radial direction of the drive shaft 500, the first groove 711 is provided to the left of the accommodation hole 721, and the second groove 731 is provided to the right of the accommodation hole 721.

When the second recess 731 is aligned with the receiving hole 721, and the front handle 300 rotates to drive the handle turning member 710, the sidewall of the first recess 711 presses the first clutch member 740 to exit the first recess 711 and enter the second recess 731, so that the front handle 300 is in a free state.

After the front handle 300 is returned to the original position, the first clutch 740 does not necessarily return to the first recess 711, and when the user operates the operating key 800 in the door, the stopper 730 moves, and the sidewall of the second recess 731 presses the first clutch 740 to make it exit the second recess 731 and enter the first recess 711, so that the handle turning member 710 and the transmission shaft connecting member 720 are combined by the first clutch 740, and the front handle 300 is in a normally open state.

For another example:

the accommodation hole 721 is a horizontal hole provided on the transmission shaft connector 720 in parallel to the axial direction of the transmission shaft 500, the first groove 711 is located in front of the accommodation hole 721, and the second groove 731 is located behind the accommodation hole 721. The front and rear are distinguished by the directions of the front and

rear panels

100 and 200, i.e., the direction toward the outside of the door and the direction toward the inside of the door.

A first groove 711 is formed on a rotation plane of the handle turn piece 710 (first cam).

The second groove 731 is formed on the rotation plane of the stopper 730 (second cam).

The plane of rotation of the handle turn 710 and the plane of rotation of the stop 730 at least partially overlap to enable the second recess 731 to align with the receiving aperture 721. When the second recess 731 is aligned with the receiving hole 721, and the front handle 300 rotates to drive the handle turning member 710, the sidewall of the first recess 711 presses the first clutch member 740 to exit the first recess 711 and enter the second recess 731, so that the front handle 300 is in a free state.

In this arrangement, after the front handle 300 is returned to the original position, the first clutch member 740 does not necessarily return to the first recess 711, and when the user operates the operating key 800 in the door, the stopper 730 moves, and the sidewall of the second recess 731 presses the first clutch member 740 to make it exit the second recess 731 and enter the first recess 711, so that the handle turning member 710 and the transmission shaft connecting member 720 are coupled by the first clutch member 740, and the front handle 300 is normally open.
