Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

As shown in fig. 1 to 7, an electronic lock with a hidden mechanical unlocking function includes a housing 1, and an electronic lock structure and a mechanical lock structure are disposed in the housing 1; the electronic lock structure comprises an input panel 11 and a lock wheel 2 which are arranged on the front surface of a shell 1, the electronic lock structure comprises a lock cylinder 4 arranged in the shell 1 and a sleeve 5 sleeved outside the lock cylinder 4, the lock wheel 2 is connected with the sleeve 5 and can drive the sleeve 5 to synchronously rotate, a decorative plate 3 is detachably arranged at the end part of the lock wheel 2, and the decorative plate 3 covers the end part of the lock wheel 2 to cover the sleeve 5 and the lock cylinder 4 of the mechanical lock so as to realize a hiding function; the lock wheel 2 is provided with a bolt hole 25 at the side, and the decorative plate 3 is detached by inserting a bolt into the bolt hole 25, so that the hidden mechanical lock is exposed.

The lock wheel 2 is provided with a bearing platform 23 for placing the decorative plate 3, an inclined stop block 21 and a flat stop block 22 are arranged below the bearing platform 23, the bottom of the decorative plate 3 is provided with a fixture block 31 and a fixture strip 32, the fixture block 31 is clamped at the bottom of the flat stop block 22, the end part of the fixture strip 32 is provided with a fixture strip end 33 with an inclined bottom surface, and the fixture strip end 33 is clamped at the bottom of the inclined stop block 21; the inclined plane cooperation of card strip end 33 the oblique top surface work of oblique dog to make card strip 32 take place deformation when installation decorative board 3, with this installation can be accomplished.

The latch hole 25 is located below the angular stop 21 and faces the gib head 33 mounted thereto.

A connecting part 24 is arranged in the lock wheel 2, a connecting screw hole 52 is arranged at the end part of the sleeve 5, and the connecting part 24 is connected with the sleeve 5 through a bolt.

The joint of the bottom surface of the decorative plate 3 and the clamping strip 32 is provided with a thumb groove 34 which is convenient for fingers to insert.

The top surface of the decorative plate 3 is provided with an indication point 35, the shell 1 is provided with a working state mark 111 on the front side, the indication point 35 is matched with the working state mark 111 to display the working state of the current electronic lock when the lock wheel 2 rotates.

The back of the shell 1 is fixedly connected with a lock shell 12, a mounting nut 13 is arranged on the lock shell 12, and the lock shell 12 is matched with the mounting nut 13 to mount the shell 1 on a door panel.

The sleeve 5 is rotatably sleeved in the lock shell 12, and the tail end of the lock core 4 extends out of the lock shell 12 and is connected with a locking plate 14; in the locking state, the relative movement between the lock cylinder 4 and the sleeve 5 is blocked by the locking card 41, so that the lock cylinder 4 cannot be rotated; after the key 30 is inserted, the lock cylinder 4 and the sleeve 5 can rotate relatively, so that the unlocking function is realized. Whether the locking and unlocking structures and functions are described in detail

A locking groove 51 is formed outside the sleeve 5, an electromagnetic limiting device 6 is arranged inside the shell 1, and the electromagnetic limiting device 6 extends out or retracts into a locking rod 61 in a controlled manner; when the locking rod 61 is inserted into the locking groove 51, the sleeve 5 is limited to rotate so as to realize locking, and when the locking rod 61 is separated from the locking groove 51, unlocking is realized.

An input panel 11 for inputting a password is arranged on the housing 1, and the input panel 11 can drive the electromagnetic limiting device 6 to retract the locking rod 61 after a correct password is input.

The lock wheel 2 of the device is arranged outside the lock sleeve 5, and the lock wheel and the lock sleeve can synchronously rotate. The device is internally provided with two sets of locking and unlocking mechanisms, one set is an electronic lock, and the other set is a mechanical lock.

The mechanical lock comprises a lock cylinder 4 and a locking card 41 arranged in a lock sleeve 5. When locking, the locking card 41 is caught in the key cylinder 4 and the lock sleeve 5, so that the key cylinder 4 and the lock sleeve 5 cannot rotate relatively. And the lock sleeve 5 is clamped by the electromagnetic limiting device and cannot rotate, so that the locking work is finished. When unlocking, a key is inserted into the lock cylinder 4, so that the locking card 41 moves and does not block the lock cylinder 4 and the lock sleeve 5, the lock cylinder 4 and the lock sleeve 5 can rotate relatively, the lock cylinder 4 is rotated, and unlocking is realized.

The electronic lock mainly uses an electromagnetic limiting device to extend and retract the locking rod 61 and match the locking groove 51 on the lock sleeve 5, so as to lock and unlock the lock sleeve 5. When unlocking, the electromagnetic limiting device retracts into the locking rod 61, so that the electromagnetic limiting device is not clamped in the locking groove 51 any more, and therefore the lock sleeve 5 can drive the lock cylinder 4 to rotate together, and unlocking is completed.

The device is unlocked by using the password at ordinary times. The user inputs the password through the input panel, and if the password is correct, the electromagnetic limiting device is started to work, and the locking rod 61 which extends out before being retracted during locking and is clamped into the locking groove 51 is retracted. After the locking rod 61 leaves from the locking groove, the user can unlock the door by rotating the lock wheel 2.

If the battery energy is used up or the electronic lock mechanism fails, unlocking can be performed mechanically.

The device hides the mechanical unlocking mode for aesthetic appearance and safety. Specifically, the lock wheel 2 is clipped by the decorative plate 3 so as to cover the end faces of the lock sleeve 5 and the lock cylinder 4 and the insertion hole for inserting the key. With this arrangement, it is difficult to see that the mechanical unlocking mode can be adopted from the appearance. Namely, the hidden purpose is realized.

When mechanical unlocking is needed, other rigid rod-shaped objects with consistent diameters, such as pins, poking pins or nails, are inserted into the plug pin holes 25 and push against the clamping strip end 33 to move the clamping strip. This causes the strip 32 to bend. Because the inclined plane influence of card strip end 33 bottom, after hard rodlike thing inserts, can even push up card strip end 33 and move upward, because the card strip 32 has taken place the bending, then no longer by oblique dog 21 to make decorative board 3 this side can push up, exposed thumb groove 34. The decorative plate 3 can then be flipped up and removed to expose the lock hole by applying a finger to the thumb groove 34. Thus, the mechanical unlocking can be carried out by using the key.

The clamping block 31 of the device is used for being matched with the clamping strip 32 to work, and the decorative plate 3 is arranged on the lock wheel 2.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
