The operation of the control mechanism 100 for a door lock according to the present disclosure will be described with reference to fig. 1 to 10 again.

In the upper safety state, as shown in fig. 3 to 4, the electric release and reset function is completed by the following sequence of actions: the electric releasing device 13 rotates counterclockwise around the shaft 131, the driving finger 132 on the electric releasing device 13 contacts the upper side of the first end 191 on the upper/lower safety transition device 19 to push the upper/lower safety transition device 19 to rotate around the second end 192, and the lower side of the first end 191 pushes the sliding guide 181 on the main releasing device 18, so as to push the main releasing device 18 to rotate counterclockwise around the shaft 131, thereby realizing the electric releasing function.

After the electric release function is completed, the electric release device 18 and the first arm 171 of the second return spring 17 push the second lever 134 of the electric release device 13 and the return finger 182 of the main release device 18, so that the electric release device 13 and the main release device 18 are returned to the initial positions.

In the upper safety state, the mechanical external opening function cannot be realized, and the movement principle is shown in fig. 5. Under the action of external force, the mechanical release device 11 rotates counterclockwise around the shaft 111, and the first finger 113 on the mechanical release device 11 cannot contact the upper side of the first end 191 on the upper/lower safety transition device 19, and cannot drive the upper/lower safety transition device 19 to release around the second end 192. After the external force is removed, the first end of the first return spring 12 exerts a return torque on the second finger 112 of the mechanical release 11, thus ensuring that the mechanical release 11 returns to the initial position.

The arming action is shown in fig. 7, the up/arming device 15 rotates counterclockwise about the third axis 154, the transition device retaining spring 110 loaded on the up/arming device 15 also rotates counterclockwise under the action of the protrusion 152 on the up/arming device 15, both sides of the second end 192 on the up/arming transition device 19 are respectively caught by the first arm 1101 and the second arm 1102 of the transition device retaining spring 110, and the first end 191 on the up/arming transition device 19 slides in the slide guide 181 of the main release 18. After the arming/disarming unit 15 is in the disarming position, the arming/disarming transition unit 19 is brought to the disarming state under the urging of the transition unit retaining spring 110 and the guidance of the slide guide 181 of the main release unit 18.

In the arming state, the mechanical release device 11 rotates counterclockwise around the first shaft 111 under the action of external force, when the first finger 113 on the mechanical release device 11 contacts the upper side of the first end 191 of the upper/arming transition device 19, the upper/arming transition device 19 is pushed to rotate downward around the second end 192, and when the lower side of the first end 191 on the upper/arming transition device 19 contacts the sliding guide 181 of the main release device 18, the main release device 18 is simultaneously pushed to release clockwise along the second shaft 131.

When the releasing action is completed, the external force is removed, the first end of the first return spring 12 pushes the second finger 112 of the mechanical releasing device 11, and the mechanical releasing device 11 returns to the initial position; the first arm 171 of the second return spring 17 pushes the return finger 182 of the main release 18, the main release 18 returning to the initial position.

The mechanical release device 11 is released while performing the release action, as shown in fig. 6, and the movement mode is as follows: the up/down fuse 15 reaches a relieved condition about the third shaft portion 154 and allows the up/down fuse 15 to remain in the relieved condition at all times under the action of the up/down fuse spring 14. Since the right side of the first end 191 of the over/arming transition 19 is blocked by the first finger 113 of the mechanical release 11, the over/arming transition 19 cannot reach the arming position. The second arm 1102 of the transition means retention spring 110 is stopped by the protrusion 152 of the arming/disarming means 15, the second end 192 of the arming/disarming transition means 19 pushes the first arm 1101 of the transition means retention spring 110 to the left in the figure in the slot 153 of the arming/disarming means 15, and the transition means retention spring 110 provides a reset force in the right direction in the figure and is transmitted to the left of the second end 192 of the arming/disarming transition means 19 through the first arm 1101, thereby pushing the arming/disarming transition means 19 to the right in the figure. When the external force on the mechanical release device 11 is removed, the first end of the first return spring 12 pushes the second finger 112 of the mechanical release device 11, and the mechanical release device 11 returns to the initial position. The arming/disarming transition 19 slides into the armed section 153 of the arming/disarming device 15 to an armed state by the first arm 1101 of the transition device retaining spring 110.

The external release in the unsecured state is shown in fig. 8. The motion principle is as follows: the mechanical releasing device 11 rotates counterclockwise around the first shaft 111 under the action of an external force, the first finger 113 of the mechanical releasing device 11 pushes the upper side of the first end 191 of the upper/lower safety transition device 19, and the lower side of the first end 191 of the upper/lower safety transition device 19 pushes the sliding guide 181 of the main releasing device 18, so as to drive the main releasing device 18 to perform clockwise rotation releasing action around the second shaft 131.

The mechanical release 11 is secured during release as shown in fig. 9. The motion principle is as follows: the mechanical releasing device 11 rotates counterclockwise around the first shaft 111 under the action of an external force, the first finger 113 of the mechanical releasing device 11 pushes the upper side of the first end 191 of the upper/lower safety transition device 19, and the lower side of the first end 191 of the upper/lower safety transition device 19 pushes the sliding guide 181 of the main releasing device 18, so as to drive the main releasing device 18 to perform clockwise rotation releasing action around the second shaft 131. During the release process, the upper/lower safety device 15 reaches the upper safety position under the action of an external force and is maintained in the upper safety state under the action of the upper/lower safety spring 14. The first arm 1101 of the transition device retaining spring 110 is pushed by the left side of the boss 152 of the up/down safety device 15, also reaching the up safety position. The first end 191 of the arming transition 19 is restrained from moving to the left to the arming position by the first finger 113 of the mechanical release 11 and the sliding guide 181 of the main release 18. The right side of the second end 192 of the over/un-fused transition piece 19 carries the second arm 1102 of the transition piece retaining spring 110 still in the un-fused position. However, as the angle between the first and second arms 1101, 1102 of the transition device retaining spring 110 becomes larger, the second arm 1102 provides a greater pushing force to the up/down transition device 19 to the left as viewed.

When the external force on the mechanical release device 11 is removed, the first end of the first return spring 12 pushes the second finger 112 of the mechanical release device 11 to return the mechanical release device 11 to the initial position. The first arm 171 of the second return spring 17 pushes the return finger 182 of the main release 18, the main release 18 returning to the initial position. The restraining feature formed by the first finger 113 of the mechanical release 11 and the sliding guide 181 of the main release 18 is cancelled and the over/un-safing transition 19 returns to the over-safing state within the slot 153 of the over/un-safing 15 under the action of the second arm 1102 of the transition retaining spring 110.

In the electric release in the arming state, as shown in fig. 10, the electric release device 13 performs a counterclockwise rotation motion around the second shaft portion 131, and the first rod portion 133 on the electric release device 13 also performs a counterclockwise rotation motion, because the first end portion 191 of the upper/arming transition device 19 is not within the pushing range of the driving finger portion 132 of the electric release device 13, the main release device 18 cannot be pushed to perform the release motion, and the electric release function cannot be realized. When the electric release is finished, the second lever 134 of the electric release device 13 is driven by the first arm 171 of the second return spring 17 to return to the initial position.

The control mechanism for the door lock can push the main release device to rotate through the motor in an upper safety state, so that a quick electric release function is realized, but in the state, the release action of the mechanical internal release or the mechanical release device cannot transfer the main release lever; in the control mechanism for the door lock, in the safety release state, the electric release path is disconnected, the electric release function cannot be realized, but the release action of the inner release device or the external mechanical release device can be transmitted to the main release device, so that the mechanical release function is realized.

The control mechanism for the door lock is particularly suitable for the door lock with an electric release function, and under the condition of normal use, the door lock is in an upper insurance state, so that the door can be easily opened through electric release; under emergency or the electronic unable circumstances of opening, the lock is in the state of relieving insurance, can open the lock through mechanical release route, guarantees that the door can all open under any operating mode.

The control mechanism for the door lock has the advantages that the electric release function, the mechanical release function and the upper safety release function are fused and redistributed, the design structure is simplified, the number of parts is reduced, the cost of the parts is reduced, the electric release function and the mechanical release function are arranged in different safety states, the possibility that two release actions are actuated simultaneously is completely eliminated, and the perception quality of a user is improved.
