Abstract

The utility model relates to a fingerprint key safety lock used for an electric bicycle and a bicycle. The fingerprint key safety lock comprises a lock body, a lock stick, a sealing element and a fixing element; a lock hole, a fixing screw hole and a lock stick inserting hole are arranged on the lock body; a power source interface, a key hole sleeve, a lock pin, a fingerprint chip circuit module and a fingerprint identification window are arranged on the lock body; the sealing element is in a reversed-U shape structure and is clamped on the lock body, and the left side, the upper side and the right side of the lock body are covered by the sealing element; a power source protection hole is arranged at the lower end at the left side of the sealing element; the fixing element is an accessory for fixing the lock body and an electric bicycle frame and a bicycle frame together; a fixing screw is screwed in the fixing screw hole on the lock body through a small hole of the fixing element and a small through hole on the sealing element; and the sealing element is used for sealing the key hole sleeve. Under the circumstance that the fingerprint chip circuit module is out of operation, the lock can be unlocked by a key by dismounting the fixing element and the sealing element; the fingerprint key safety lock is convenient and fast to mount and has lower cost; the intellectualization degree of the safety lock is improved, the manual unlocking function is kept, the antitheft function of the electric bicycle is improved, and the safety lock can be widely applied in the antitheft field of the electric bicycle.

Description

Fingerprint key lock

Technical field

The utility model relates to the theftproof lock technology, particularly is used for a kind of fingerprint key lock of electric bicycle and bicycle.

Background technology

At present, the lock of various structures is widely used in the antitheft field of electric bicycle and bicycle.Yet the identical probability height of the key of traditional key lock, and lock core also than be easier to by pry open, so theftproof performance is poor, and also there is the antijamming capability problem in the lock that has remote control, can not guarantee that lock is having work normal, safe under the situation of interference source, simultaneously run into that remote-control key is lost or remote-control key lost efficacy the time, make the car owner also can't open lock.If keep manual unlocking function, can make remote control lose meaning again.

And existing anti-theft vehicle lock technology can't satisfy should the applying electronic remote control, can keep the requirement of manual unlocking function again, to guarantee that simultaneously lock core can not pried open easily yet.Thereby the theftproof lock technology of electric motor car still has not enough and improved space.

Summary of the invention:

The purpose of this utility model provides a kind of new anti-theft vehicle lock technical design scheme exactly for overcoming the deficiencies in the prior art, carries out brand-new improvement from structure, makes its more reasonable structure, simple, practicability and effectiveness.

The utility model is to realize by such technical scheme: a kind of fingerprint key lock, comprise lock body and lock rod, and it is characterized in that, also comprise seal, fixture; Be processed with lockhole, fixing threaded hole and lock rod jack on the lock body, power interface, key borehole jack, lock pin, fingerprint chip circuit module and fingerprint recognition window are installed on the lock body;

Seal is for being inverted the U font structure, seal is installed on the lock body, left side, upside and the right side of lock body are surrounded, the lower end, left side of seal is that power supply protects mouth, the position corresponding power interface of its circular open, the upside of seal is provided with the lock rod open-work of two symmetries and the little open-work of two symmetries, the corresponding lockhole in position of lock rod open-work, the corresponding fixing threaded hole in the position of little open-work; Fixture is with lock body and the fixing accessory of vehicle frame, and hold-down screw is successively by in the fixing threaded hole on the little open-work screw-in lock body on the open-work on the fixture, the seal;

Seal is used to seal the key borehole jack; The fingerprint chip circuit module that external power supply is adorned in lock body by power interface provides power supply, and the fingerprint recognition window that is connected with fingerprint chip circuit module circuit is installed in surface of lock body; Fingerprint chip circuit module connects and drives electronic lock pin drive unit, connects lock pin by electronic lock pin drive unit; The key borehole jack passes through mutually with lock pin.

Electronic lock pin drive unit is installed the connecting rod that connects lock pin by the motor-driven wheel disc on the wheel disc, wheel disc rotational angle, connecting rod drive the lock pin action.

The utlity model has following characteristics: use the electronic lock pin drive unit of fingerprint chip circuit module drive switch lock under the normal condition, under the situation that fingerprint chip circuit module lost efficacy, unload fixture and seal can open the lock with the key; It is convenient that the utility model is installed, and irrelevant with vehicle, cost is lower; Both improved the intelligent degree of lock, kept manual unlocking function again, and improved and improved the electric motor car anti-theft feature, but in electric motor car antitheft field extensive use.
