Description
Technical Field
[0001] The present invention relates to the technical field of fingerprint locks, in particular to a fingerprint door lock. Background Art
[0002] Fingerprint lock is a kind of intelligent lock that uses the fingerprint of human finger as the identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint lock is generally composed of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replicability of live fingerprints determine that fingerprint lock is the safest type of lock among all locks currently. In addition to fingerprint identification, fingerprint locks should be equipped with emergency mechanical keys according to the regulations of the Ministry of Public Security.
[0003] From a macro perspective, the existing fingerprint door lock field has always retained the traditional mechanical atmosphere. Not only that, most of the door fields use ball locks, and the update and iteration of split lock technology (handle and mechanical lock cylinder are separated) can only continuously polish the structure and change the material properties, lacking innovation. With the advancement of technology, some businesses have integrated biometric technology into door locks to replace traditional mechanical keys. The above-mentioned innovative forms are understandable and bring many conveniences to users, but convenience is not the ultimate mission of fingerprint locks.

A lock hole silicone cover 29 is provided, a lock core lock column 30 is movably installed below the inner surface of the lock core 16, a fingerprint module 7 is fixedly installed on the front of the front handle 1, a motor 8 is installed inside the front handle 1, a control board 31 is installed on the top of the motor 8, a first silicone back cover 32 is fixedly connected to the inner side of the face cover 5, a regional isolating piece 33 is fixedly installed between the inside of the front handle 1 and the motor 8, and the output end of the motor 8 is connected to the rotor 9 and the rotor convex position 10, the outer surface of the rotor 9 is sleeved with a front mechanism fixing 37, one end of the inner surface of the battery 21 is movably connected with a positive pole spring 38, the outer surface of the positive pole spring 38 is sleeved with a rear mechanism fixing 39, the rotor recesses on the outer surface of the rotor 9 are movably connected with motor lock columns 11, both sides of the inner surface of the clutch male 4 are provided with a first clutch male groove 12, one side of the outer surface of the clutch male 4 is provided with a second clutch male groove 13, a clutch female 14 is installed inside the front handle 1, and the inner surface of the first clutch male groove 12 is adapted to the outer surface of the motor lock column 11;A lock core 16 is installed inside the front handle 1, one end of the lock core 16 is fixedly connected to a lock core clutch 17, lock core convex positions 18 are provided on both sides of the lock core clutch 17, a lock strain channel 19 is provided on one side of the surface of the clutch mother 14, and a lock strain 20 is movably connected inside the lock strain channel 19, the inner side of the auxiliary cover 6 is fixedly connected to a second silicone back cover 40, and screws 15 are installed and connected on both upper and lower sides of the auxiliary cover 6, one end of the screw 15 is threadedly connected to the inner surface of the screw rod 34, through the rotor 9, the rotor convex position 10, the motor lock column 11, the first clutch male groove 12, the second clutch male groove 13, the clutch mother 14, the clutch male concave position 15, the lock core convex position 18, the clutch male concave The cooperation between the position 15 and the lock stock 20 can realize the collection of the two forms of authority collection, the mechanical lock core and the biometric fingerprint, and realize the common fusion of the clutch in a simple way. Through the cooperation between the anti-lock button 23, the push button 24, the push piece 25, the anti-lock piece 26, the anti-lock spring 27 and the anti-lock slot 28, the anti-lock structure and the power supply can be integrated into the auxiliary handle 2, so that the security is further improved. The front handle 1, the auxiliary handle 2, the rear mechanism fixing 39, the front mechanism fixing 37, the first silicone back cover 32, the second silicone back cover 40 and other common components are used, which greatly reduces the cost and component categories. The two modules are made of stainless steel 304 to achieve modularization. ;
[0032] The front mechanism fixing 37 and the rear mechanism fixing 39 fix the two modules in front and back through the handle opening, so that no screws are visible on the surface. In addition, the area isolation part 33 is a metal part to ensure that the internal core components cannot be damaged after the fingerprint chip is forcibly destroyed. In addition, the mechanical key is blocked with a keyhole silicone cover 29 as an emergency backup, which will not cause damage to the lock core in the event of a fire. In addition, the two modules can be replaced instead of repair, and the handle plus module can be used on other panels to achieve functional superposition. In addition, the full lock is made of stainless steel 304 material to greatly enhance the safety performance.
[0033] When in use, after the fingerprint module 7 receives the authority, the motor 8 rotates to drive the rotor 9, and the rotor 9 rotates to push the motor lock column 11 into the first clutch male groove 12. At this time, the front handle 1 is rotated. Since the motor lock column 11 has no movable space, it will be engulfed by the rotor convex position 10 and the clutch male concave position 15, so that the clutch male () is linked to drive the lock tongue (3) to unlock; in the same mechanical key unlocking form, when the lock core 16 matches the key authority, a movable space is provided for the lock core lock column 30, the lock core 16 can be rotated, and the lock core clutch 17 rotates, and the lock strain 20 is pushed into the clutch male concave position 15 through the lock core convex position 18. At this time, due to the lock strain 20, the lock strain channel 19, the lock core convex position 18, and the clutch male concave position 15, the clutch male 4 is linked to drive the lock tongue 3 to unlock; in the state of no authority, the front handle 1 is not linked with the clutch male 4, so the lock is closed.
[0034] A replaceable battery 21 is arranged in the rotating column of the auxiliary handle 2, and a button anti-locking structure is arranged on the side of the battery 21. When the front handle 1 receives the authorization to unlock, the front handle 11 rotates and will be linked with the clutch male 4, the square tube 35, the lock tongue 3 and the auxiliary handle 2. In this way, the anti-locking mechanism prevents the auxiliary handle 2 from being linked, thereby achieving the anti-locking effect. The anti-locking button 23 extends into the anti-locking slot 28 of the auxiliary cover by pressing the anti-locking piece 26, so that the auxiliary handle 2 cannot rotate, and the front handle 1 cannot be unlocked even if it receives any unlocking authority.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
