Description

Technical Field

[0001] The present invention relates to the technical field of locks, in particular to a small, fully automatic lock body with rapid electromechanical separation. Background Art

[0002] In existing locks that can achieve automatic locking, a cross-tongue guide plus a triangular tongue touch electronic sensor is used to achieve electronic automatic locking. During operation, when the door is opened, the motor drives the gear to drive the main tongue and the oblique tongue (guide tongue) of the lock body to retract, and then after the door is opened, the oblique tongue must be extended back to its original extended state, thereby playing the role of guiding and triggering automatic locking when closing the door: when closing the door, the oblique tongue and the main tongue need to be synchronized. This will cause the motor to drive the main tongue and the oblique tongue (guide tongue) out of sync throughout the entire process, and the fully automatic lock bodies on the market use the motor to drive the gear of the reduction box and then drive the lock bolt to lock and close. During operation, the gears must be tightly engaged with each other to transmit power, but when the motor loses its function, a mechanical structure is required to ensure the disengagement of the gears for mechanical unlocking.

[0003] To achieve the disengagement of gears, the current electronic locks on the market use a swinging gear inside a reduction gear box. After the lock is in place, the motor must be reversed by a certain angle to achieve the disengagement of the gears. This structure cannot guarantee that the gears can be disengaged with every rotation.

[0004] The applicant has discovered that the prior art has at least the following technical problems:

[0005] (1) After the lock is in place, the motor is damaged or the power is cut off, causing the motor to be unable to reverse normally, the gears are locked and cannot be disengaged, resulting in the mechanical unlocking being unable to open;

[0006] (2) During the locking process, there is foreign matter or displacement in the door frame, causing the lock head to be stuck on the door frame and unable to return to its original position. The gears may also be locked, making it impossible to mechanically open the lock body. Summary of the Invention

[0080] The workflow of the present invention is as follows:

[0081] When the triangular tongue assembly 3 closes the door and contacts the door frame, the triangular tongue assembly 3 is compressed into the lock body, and the triangular connecting rod 32 contacts the triangular tongue sensing component. After a certain period of contact, the circuit board assembly 11 receives the locking signal, and the motor assembly 10 works to drive the transition gear 411 to move, the transition gear 411 drives the upper gear 412 to move, the upper gear 412 drives the lower gear 421 to move, the lower gear 421 drives the lock bolt gear 422 to move, the lock bolt gear 422 drives the lock bolt lever 61 to move, and the lock bolt lever 61 drives the lock head 63 to lock and complete the locking action.

[0082] When the door opening signal is received, the motor assembly 10 starts to work, driving the transition gear 411 to move, the transition gear 411 drives the upper gear 412 to move, the upper gear 412 drives the lower gear 421 to move, the lower gear 421 drives the lock bolt gear 422 to move, the lock bolt gear 422 drives the lock bolt lever 61 to move, and the lock bolt lever 61 drives the lock head 63 to retract.

The circuit board assembly 11 receives the lock body in place signal, and the motor assembly 10 stops working. After the motor assembly 10 delays for 3 seconds, the motor reverses for a certain time, releasing the inclined bolt mechanism 71 to return, and the unlocking action is completed.

[0083] When the electronic components fail, the door can be opened mechanically using the lock cylinder 81 or the square steel dial 91.

The conical protrusion 521 on the clutch pull tab 52 moves and raises the clutch pad 53. The raised clutch pad 53 raises the upper gear 412, and the upper gear 412 and lower gear 421 are disengaged, completing the electromechanical separation. The lock cylinder 81 continues to rotate, driving the key gear 82 to rotate. The key gear 82 drives the lock bolt gear 422, which drives the lock bolt lever 61 to move. The lock bolt lever 61 drives the lock cylinder 63 to retract. As the lock bolt gear 422 returns to its original position, it contacts the latch bolt lever 72, which drives the latch bolt mechanism 71 to retract. After the door opening action is completed, the lock cylinder 81 is released, and the latch bolt mechanism 71 returns to its original position, completing the entire door opening action.

[0084] When the square steel dial 91 is used to open the door, the square steel dial 91 drives the square steel clutch plate 93, which drives the clutch assist plate 51, which drives the clutch pull plate 52. The conical protrusion 521 on the clutch pull plate 52 moves to raise the clutch pad 53. The clutch pad 53 is raised, which drives the upper gear 412 to raise. The upper gear 412 and the lower gear 421 are disengaged, and the electromechanical separation is completed. The square steel dial 91 continues to move, and the square steel dial 91 drives the square steel tooth plate 92 and the latch bolt 72. The square steel tooth plate 92 drives the lock lever 61, and the lock lever 61 drives the lock head 63 to retract. At the same time, the square steel dial 91 drives the latch bolt 72, which drives the latch bolt mechanism 71 back to its original position, completing the mechanical door opening method. When the square steel dial 91 is released, the square steel clutch plate 93 returns to its original position.
