Description

Technical Field

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

[0002] In the existing locks that can achieve automatic locking, cross tongue guide plus triangular tongue touch electronic induction parts are 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 the oblique tongue must be extended back to its original extended state after the door is opened, so as to guide and trigger automatic locking when closing the door: when closing the door, the oblique tongue and the main tongue need to come out synchronously. This will cause the motor to drive the main tongue and the oblique tongue (guide tongue) to be out of sync throughout the process, and the fully automatic lock body on the market uses the motor to drive the gear of the reduction box and then drive the lock bolt to lock and close the lock. During operation, the gears must be tightly engaged to transmit the transmission, but when the motor fails or the power is accidentally cut off, a mechanical structure is required to ensure the disengagement of the gears for mechanical unlocking.

[0003] In order to achieve the disengagement between gears, the electronic locks currently on the market use a swinging gear in the reduction box. After locking in place, the motor must be reversed by a certain angle to achieve the disengagement of the gears. Its structure cannot guarantee that each rotation can disengage the meshing between the gears.

[0004] The applicant has found 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

[0047] When the key is used to unlock the door, the lock core dial wheel of the lock core assembly 6 drives the clutch plate assembly 15 to move, and the clutch plate assembly 15 drives the clutch dial wheel 1103 to move, so as to achieve the clutch of the clutch dial wheel 1103 and the gear 1101. The lock core dial wheel of the lock core assembly 6 continues to rotate, driving the key paddle assembly 16 to rotate, and the rotation of the key paddle assembly 16 drives the second tooth plate assembly 1902 to be connected in transmission, and the second tooth plate assembly 1902 is connected in transmission with the bolt assembly 8.

[0048] A square steel clutch assembly 13 and a clutch assisting plate assembly 14 are provided on the square steel dial head 12 of the handle assembly. The square steel dial head 12 is transmission connected to the square steel clutch assembly 13, the square steel clutch assembly 13 is transmission connected to the clutch assisting plate assembly 14, and the clutch assisting plate assembly 14 is transmission connected to the clutch plate assembly 15.

[0049] When the handle is used to unlock the door indoors, the inner handle is rotated, the square steel dial head 12 drives the square steel clutch assembly 13 to rotate, the square steel clutch assembly 13 drives the clutch assisting plate assembly 14 to rotate, the clutch assisting plate assembly 14 drives the clutch plate assembly 15 to move, the clutch plate assembly 15 drives the clutch dial wheel 1103 to move, the clutch dial wheel 1103 is disengaged from the gear 1101, and the electromechanical separation is completed, thereby realizing rapid unlocking, high reliability and simple structure.

[0050] Specifically, the clutch plate assembly 15 includes a clutch plate and an elastic assembly, one end of the elastic assembly is fixedly connected to the lock housing 17, the other end of the elastic assembly is connected to the clutch plate, and the clutch plate is connected to the clutch dial 1103.

[0052] like Fig.11 As shown, the motor oblique tongue paddle 20 is arranged on the square steel paddle head 12, and a square steel tooth plate 18 is also arranged on the square steel paddle head 12. The square steel tooth plate 18 is transmission connected with the second tooth plate assembly 1902. The rotation of the second tooth plate assembly 1902 drives the square steel tooth plate 18 to rotate, and the square steel tooth plate 18 further drives the motor oblique tongue paddle 20 to rotate.

[0053] The size of the clamping groove on the square steel tooth plate 18 is larger than the clamping column on the square steel pull head 12. This makes the square steel tooth plate 18 and the square steel pull head 12 not transmit within a certain angle.

[0054] like Fig. 9 As shown, the bolt assembly 8 includes a bolt head 801, a bolt plate 802, an oblique tongue push plate 803, and an oblique tongue paddle 804. The bolt head 801 is fixed to the bolt plate 802. The bolt plate 802 is slidably disposed on the lock housing 17. The bolt plate 802 is in transmission connection with the transmission assembly 19. The motor assembly 11 drives the bolt plate 802 through the transmission assembly 19 to realize locking of the bolt head 801.

[0055] One end of the inclined tongue push plate 803 is slidably disposed on the locking bolt plate 802, and the other end of the inclined tongue push plate 803 is rotatably connected to the inclined tongue paddle 804.

[0060] When unlocking, the circuit board body 1002 detects the door opening signal and sends a signal to the motor 1104. The motor 1104 rotates, and the motor assembly 11 drives the transmission assembly 19. The transmission assembly 19 drives the lock bolt assembly 8 to retract. After retracting to a certain extent, the first tooth plate assembly 1901 drives the motor oblique tongue paddle 20, and the motor oblique tongue paddle 20 drives the oblique tongue assembly 9 to retract, completing the door opening action.
