The following explains a method of using an electronic lock according to an embodiment of the present invention:

when the door body is in a closed state, the square bolt 21 and the latch bolt 31 extend out of the casing 1 and are clamped into a lock groove in a door frame, at this time, the locking rod 4 is located at a first rotating position, the slide roller 5 is located at a first moving position, and the latch bolt thumb wheel 91 is located at a third rotating position, as shown in fig. 1.

If the user needs to unlock the door, the driving mechanism 10 drives the third gear 73 to rotate in the counterclockwise direction (as shown in the direction R in fig. 1), the third gear 73 drives the first gear 81 and the latch dial 71 to rotate in the clockwise direction, the dial rod 72 contacts the second edge 232, and applies a force to the second edge 232 during the rotation process, so that the latch assembly 2 moves downward, and the latch 21 retracts relative to the housing 1.

Meanwhile, the first gear 81 drives the second gear 82 and the first cylinder 83 to rotate in the counterclockwise direction, and the first cylinder 83 contacts the contact end of the latch pulling member 84 during the rotation and applies a force to the contact end, so that the latch pulling member 84 rotates in the counterclockwise direction around the second rotating shaft 842. Meanwhile, the first gear 841 on the latch pulling piece 84 is engaged with the second gear 911 on the latch pulling wheel 91, so that the latch pulling wheel 91 is driven to rotate clockwise. The latch pulling wheel 91 drives the link 92 and the sliding roller 5 to move, the sliding roller 5 pushes the driving end 41 of the locking lever 4 during the movement, so that the locking lever 4 rotates around the first rotating shaft 43 in the counterclockwise direction, and then the locking end 42 of the locking lever 4 is disengaged from the locking groove 316 on the latch 31, so as to unlock the latch 31 from the locking lever 4.

After the square bolt 21 retracts and the locking end 42 of the locking rod 4 is separated from the locking groove 316 on the latch bolt 31, a user performs a door opening action, the vertical surface 312 on the latch bolt 31 is contacted with the edge of the locking groove in the door frame, and the edge of the locking groove generates acting force on the vertical surface 312, so that the latch bolt 31 rotates towards the side where the first inclined surface 311 is located around the center of the outer convex arc-shaped surface 313. When the latch bolt 31 rotates to a certain angle, the latch bolt 31 can also be operated downwards by the action force generated by the edge of the lock slot on the vertical surface 312, so that the rotating edge of the latch bolt 31 retracts relative to the shell 1, and the latch bolt 31 does not interfere with the door frame. Meanwhile, when a user performs a door opening operation, the second inclined surface 62 on the signal tongue 61 contacts with the edge of the locking groove in the door frame, and the edge of the locking groove exerts a force on the second inclined surface 62, so that the signal tongue 61 retracts relative to the housing 1, and the signal tongue 61 does not interfere with the door frame, thereby realizing the door opening, as shown in fig. 2.

When the door is opened, the latch bolt 31 and the signal bolt 61 are both out of contact with the door frame, and the signal bolt 61 is extended outwards by the elastic force of the second elastic member 65 to return to its original position (i.e. the position of the signal bolt 61 when the electronic lock is locked, as shown in fig. 1); the latch 31 is projected to the outside of the housing 1 by the elastic force of the first elastic member 34. When the latch bolt 31 extends to the outermost end, the abutting surface 315 of the limiting protrusion 314 abuts against the housing 1, as shown in fig. 6, so that the latch bolt 31 rotates to the initial position (i.e. the position of the latch bolt 31 when the electronic lock is locked, as shown in fig. 1).

In summary, when the door is opened, the latch 21 is in the retracted state, the locking lever 4 is in the second rotational position, the slide roller 5 is in the second moving position, the latch thumbwheel 91 is in the fourth rotational position, and both the latch 31 and the signal latch 61 are extended relative to the housing 1. Wherein the second rotational position, the second moving position, and the fourth rotational position are all as shown in fig. 2.

When the user needs to close and lock the door, before the door is closed, the door is in an open state, the dead bolt 21 is in a retracted state, and the latch bolt 31 is extended out of the housing 1 under the elastic force of the first elastic member 34. When the user closes the door, the first inclined surface 311 of the latch bolt 31 contacts the door frame, and the door frame exerts a force on the first inclined surface 311, so that the latch bolt 31 retracts relative to the housing 1 without interfering with the door frame. Meanwhile, when the user closes the door, the third inclined surface 63 of the signal tongue 61 contacts with the door frame, and the door frame generates acting force on the third inclined surface 63, so that the signal tongue 61 retracts relative to the shell 1, and the signal tongue 61 does not interfere with the door frame, thereby closing the door.

When the door is closed, the latch bolt 31 extends outward into the lock groove of the door frame under the elastic force of the first elastic member 34, and the signal bolt 61 extends outward into the lock groove of the door frame under the elastic force of the second elastic member 65. When the signal tongue 61 is extended outward relative to the housing 1, the detection unit 68 cannot detect the signal tongue 61, which indicates that the door is closed. If the user closes the door, the detection unit 68 can detect the signal tongue 61, which indicates that the door is not closed, the detection unit 68 sends a signal to the control system, and the control system sends a prompt to the user after receiving the signal sent by the detection unit 68.

When it is determined that the door is closed, the driving mechanism 10 drives the third gear 73 to rotate clockwise (opposite to the direction R shown in fig. 1), the third gear 73 drives the first gear 81 and the latch dial wheel 71 to rotate counterclockwise, the shift lever 72 contacts the first edge 231 and applies a force to the first edge 231 during the rotation process, so that the latch assembly 2 moves upward, and the latch 21 extends out of the housing 1 and into the locking groove of the door frame, thereby achieving locking. Meanwhile, during the counterclockwise rotation of the first gear 81, the second gear 82 rotates clockwise, the first cylinder 83 is out of contact with the contact end of the latch pulling piece 84, no force is applied to the contact end, and then the latch pulling wheel 91 is returned to the third rotational position counterclockwise by the second return torsion spring 93. The connecting rod 92 and the sliding roller 5 are driven by the latch poking wheel 91 to operate, the sliding roller 5 is separated from the contact with the driving end 41 of the locking rod 4, no force is applied to the driving end 41 any more, and then the locking rod 4 is clockwise rotated and reset to the first rotating position under the action of the first reset torsion spring 44, so that the locking end 42 of the locking rod 4 is clamped into the locking groove 316, and the latch 31 is locked, so that the locking safety is ensured.

Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the invention.
