Detailed Description

The electronic lock of the present invention includes a lock body 1 and an electronic unlocking panel 6, in this embodiment, the electronic unlocking panel 6 adopts a fingerprint identification unlocking panel, and the following explains the technical solution in detail through the fingerprint electronic lock shown in fig. 1 to 8.

The lock body 1 comprises a shell 2, a bolt mechanism 3 and a driving mechanism 4, wherein the bolt mechanism 3 is connected to the shell in a penetrating mode, the driving mechanism 4 drives the bolt mechanism 3 to move in a stretching mode, the driving mechanism 4 is controlled by a fingerprint identification unlocking panel, a lock cylinder seat 5 is arranged on the surface of the lock body 1 in a protruding mode, a containing space independent of the shell 2 is arranged in the lock cylinder seat 5 and used for containing a lock cylinder 51 for inserting a key, the fingerprint identification unlocking panel is movably covered on the surface of the end portion of the lock cylinder seat 5 to cover the lock cylinder 51, the position of a lock cylinder hole is difficult to observe directly from the outside; the back of the lock core 51 is provided with a shifting piece 52 which can rotate along with the lock core, the shifting piece 52 penetrates into the shell 2 to drive the bolt mechanism 3 to retract into the shell 2, and the mechanical unlocking of the lock body 1 is realized; under the normality, the fingerprint control actuating mechanism 4 is controlled to drive the bolt structure 3 of the lockset 1 to retract for unlocking through the fingerprint identification unlocking panel, but under the condition that the power is off or the fingerprint identification unlocking panel or the actuating mechanism 4 is damaged, the fingerprint identification unlocking panel can be moved away to expose the lock cylinder 51, and a key is inserted for mechanical unlocking. On the other hand, because the lock core 51 is arranged through the lock core seat 2 convexly arranged on the surface of the shell 2 of the lock body 1, the lock core is not arranged inside the shell any more, the internal structure of the lock body is simplified, and the lock body can be miniaturized.

Referring to fig. 4 and 5, a rotation shaft 61 extends from the back of the fingerprint identification unlocking panel towards the lock body 1, the rotation shaft 61 is arranged to deviate from the center of the fingerprint identification unlocking panel and penetrates through the lock cylinder seat 5 to be rotatably connected with the lock body 1, the fingerprint identification unlocking panel rotates by taking the eccentric rotation shaft 61 as the axis, the movable cover is closed on the surface of the end part of the lock cylinder seat 5, and the fingerprint identification unlocking panel can be exposed out of the lock cylinder 51 and inserted into a key to unlock by rotating.

Further, be equipped with the via hole 55 that supplies axis of rotation 61 to pass on the lock core seat 5, axis of rotation 61 stretches into in the casing 2, the screw is installed to the end, it is equipped with spring 9 clamp and establishes between axis of rotation 61 terminal nut and casing 2 inside to overlap on it, make axis of rotation 61 can be on via hole 55 elastic sliding, can be earlier outwards drawn when rotating fingerprint identification unblock panel, make and leave certain clearance between fingerprint identification unblock panel and the lock core seat 5, can not produce the problem of interference, more convenient rotation, on the other hand, accessible spring 9's resilience force makes fingerprint identification unblock panel tightly press on the terminal surface of lock core seat 5, can be by spacing landing of preventing when rotating to expose the lock core, can realize shielding better when closing the lock core.

In order to limit the rotation of the fingerprint identification unlocking panel on the lock cylinder seat 5 under a normal state, a key groove 53 is vertically arranged on the inner wall of the through hole 55, and a limiting key 63 is arranged on the rotating shaft 61 and slides into the key groove 53; when rotating fingerprint identification unblock panel, cooperate above-mentioned elastic construction earlier with fingerprint identification unblock panel outwards draw, make the spacing key 63 of axis of rotation 61 break away from keyway 53, just can make fingerprint identification unblock panel rotate and remove and expose lock core 51.

Preferably, the through hole 55 is arranged at the inner edge of the lock cylinder seat 5, so that the rotating shaft 61 of the fingerprint identification unlocking panel is farther away from the lock cylinder 51, and the lock cylinder 51 is easier to expose during rotation. And when fingerprint identification unblock panel through axis of rotation 61 on lock core seat 5 off-center arrange, be located the problem that clearance activity easily appears in the other end that axis of rotation 61 is radial relative, lead to fingerprint identification unblock panel can not stabilize the lid and close. Therefore, a positioning structure can be arranged at the end part, and the problems can be effectively solved, such as positioning through simple interference: the positioning column 62 is arranged on the back of the fingerprint identification unlocking panel in a protruding mode, the positioning salient point 54 interfering with the positioning column 62 in an interference mode is arranged on the edge of the inner side of the lock cylinder seat 5, and the positioning between the lock cylinder seat 5 and the fingerprint identification unlocking panel can be achieved through the matching of the positioning column 62 and the positioning salient point 54.

Preferably, the cylinder seat 5 is detachably mounted on the surface of the housing 2, and when the user does not need the mechanical unlocking function, the cylinder seat 5 can be automatically removed, and at this time, the electronic lock only has the electronic unlocking function. The shifting piece 52 is arranged at the rotating circumference of the lock cylinder, a sliding groove 21 is arranged on the shell 2 at the back of the lock cylinder seat 5 corresponding to the shifting piece 52, and the shifting piece 52 penetrates into the shell 2 through the sliding groove 21 and slides along the sliding groove 21 so as to shift the bolt mechanism 3 to move in a telescopic manner.

Referring to fig. 7 and 8, the latch bolt mechanism 3 of the present invention includes a latch bolt body 31 penetrating through the housing 2, a transmission rod 32, and an elastic member 7 clamped between the lower portion of the latch bolt body 31 and the housing, wherein the transmission rod 32 transversely extends out of the platform 33, and the driving mechanism 4 and the striking plate 52 of the lock cylinder 51 drive the latch bolt body 31 to perform telescopic movement on the housing 2 by pressing the platform 33 downwards. In order to match with the latch bolt mechanism 3, the housing 2 is provided with a guide groove 23 on the inner wall for the transmission rod 32 to slide, a positioning boss 22 is protruded on the inner side wall of the guide groove 23, and the elastic element 7 is clamped between the positioning boss 22 and the latch bolt body 31.

The driving mechanism 4 comprises a motor 41, a transmission gear set 42 and a shifting plate 43 fixed at the tail end of the transmission gear set, the shifting plate 43 and a shifting piece 52 of a lock cylinder 51 are jointly arranged above the end face of the platform 33, and the motor 41 drives the transmission gear set 42 to drive the shifting plate 43 or unlocks the transmission gear set 51 to rotate the lock cylinder 51 to drive the shifting piece 52 to drive the push-down platform 33 to drive the bolt body 31 to perform telescopic movement on the shell 2. Through the structure, the bolt mechanism 3 and the driving mechanism 4 can be arranged in the unlocking cavity 25 formed in the shell 2 in a more compact mode, so that more space can be provided in the shell 2 for arranging other components, for example, an electrical appliance cavity 24 is arranged beside the unlocking cavity 25 and is used for arranging a standby battery 8, and the condition of external power failure is prevented; under the general state, the electronic lock is supplied power by the outside, and the condition that the outage appears in one end, the electronic lock can switch stand-by battery 8 power supply at once, guarantees normal work. And the conducting wire of the electronic unlocking panel 6 penetrates into the lock body 1 through the lock cylinder seat 5 and is electrically connected with the driving mechanism 4 and the standby battery 8.
