The present invention will be further described below in conjunction with the accompanying drawings:

An electronic door lock with clutch, the door lock includes a lock body 1, the lock body 1 is provided with a main lock bolt assembly 2, a diagonal bolt assembly 3, a handle toggle assembly 4, a motor 5 and a motor output wheel 51, a fixed pile 6; The fixed pile 6 is provided with a driving gear 7 that meshes with the motor output wheel 51, and a passive gear 8 that can be driven by the driving gear or toggled by a key lock, and a main deadbolt plate 9 that can drive the main deadbolt assembly 2; The driving gear 7 is provided with an active dial 71 , the handle toggle assembly 4 is provided with a toggle block 41 that can be driven by the active dial 71 to toggle the oblique tongue assembly 3 , and the passive gear 8 is provided with a main latch plate 9 . The driven gear lever 81; between the drive gear 7 and the driven gear 8, there is a clutch mechanism 10 that can be used to toggle the oblique tongue assembly and the main lock tongue assembly with a key lock when the power is turned off. There is a top block 61 which can push up the clutch mechanism.

The clutch mechanism 10 includes an elastic bayonet 11 fixed on the driving gear, and the driven gear 8 is provided with a bayonet 82 into which the resilient bayonet 11 can be latched.

The upper part of the driven gear 8 is provided with a concave platform 83, a convex ring wall 831 is formed around the concave platform 83, the clamping groove 82 is arranged on the convex ring wall 831, the number of the clamping groove 82 is preferably two, and the two clamping grooves 82 are symmetrically arranged on the collar wall 831. The middle of the concave platform 83 is provided with a passive gear hole 84 for the fixing pile 6 to pass through, the lower part of the driving gear 7 is provided with a boss 72 which can be embedded in the concave platform, and the middle of the boss 72 is provided with a driving gear for the fixed pile to pass through. hole 73. The lower part of the driving gear 7 is provided with a bayonet fixing seat 74 for fixing the resilient bayonet 11 , and the resilient bayonet 11 includes a bayonet 111 and a return spring 112 that drives the bayonet to reset. The bayonet fixing base 74 is fixed on the boss 72 at the lower part of the driving gear 7 , and a fixing base mounting groove 721 is provided at the lower part of the driving gear 7 , and the bayonet fixing base 74 is fixed in the fixing base mounting groove 721 . The inner side of the fixing seat mounting groove 721 communicates with the driving gear hole 73 , and the outer side of the fixing seat mounting groove 721 extends to the outer wall of the boss 72 . After the top block 61 on the fixing pile 6 pushes the bayonet 111 , the bayonet 111 moves to the outside, and protrudes from the bayonet fixing seat 74 and the boss 72 . After the top block 61 does not push the bayonet 111 , the bayonet 111 returns to the bayonet fixing seat 74 under the action of the return spring 112 .

In the present invention, a convex ring wall clamping block 8311 may be provided at the lower part of the convex ring wall 831 , and a clamping groove 85 into which the convex ring wall clamping block 8311 can be clamped is provided on the driven gear 8 .

After the passive gear 8 is rotated, the passive gear lever 81 on it can drive the main deadbolt plate 9, thereby driving the main deadbolt assembly 2 to move to realize the unlocking of the main deadbolt. The driving gear is driven to rotate, and the active dial 71 on the driving gear 7 drives the dial 41 on the handle toggle assembly 4, so that the toggle assembly 4 toggles the oblique tongue assembly 3 to realize the oblique tongue unlocking. At this time, both the main deadbolt assembly 2 and the oblique bolt assembly 3 of the door lock are opened to achieve mechanical unlocking.

When the existing door lock is powered off, the output wheel of the motor locks the driving gear, and it is difficult to use the key lock to drive the passive gear or the driving gear to rotate. It is very difficult to open the door lock, and some even cannot open the door lock at all. In the present invention, in the case of power failure, the output wheel of the motor locks the driving gear, but the passive gear can be toggled by the key lock. After the passive gear rotates at a certain angle, the top block 61 on the fixed pile 6 pushes the elastic card pin 11 into the card slot. 82, so that the passive gear can drive the driving gear to rotate. At this time, the passive gear lever 81 on the passive gear 8 can drive the main deadbolt plate 9, thereby driving the main deadbolt assembly 2 to move to realize the unlocking of the main deadbolt. The active toggle block 71 on the gear 7 drives the toggle block 41 on the handle toggle assembly 4, so that the toggle assembly 4 toggles the oblique tongue assembly 3 to unlock the oblique bolt. After the driven gear 8 rotates at a certain angle, when the oblique tongue assembly 3 can no longer move, the driving gear can no longer rotate. Under the action of resistance, the elastic bayonet 11 withdraws from the bayonet slot 82, and the bayonet 111 is driven by the return spring 112 to reset, passively The gear can no longer drive the driving gear to rotate.
