Summary of the invention
The purpose of this utility model provides a kind of electrostatic induction Fingerprint Lock, and it mainly is that solution existing in prior technology optical finger print lock is higher to environmental requirement, and factors such as atmosphere humidity, the temperature difference, high light are all to its influential technical problem; It has also solved the employing optical identification, carries out false fingerprint recognition easily, has the technical problem of potential safety hazard etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Electrostatic induction Fingerprint Lock of the present utility model, comprise shell, shell is connected with handle, enclosure is provided with lock body, being provided with self-locking device in the lock body is connected with handle, lock body inside is provided with the micromachine box that has motor, shell is provided with the fingerprint input device and is connected with motor, motor-driven has switch, switch is connected with dead bolt by transmission mechanism, it is characterized in that described fingerprint input device for responding to the scratch type sensor of human biological electricity, the scratch type sensor is connected with computer main board, and the computer main board motor interior with being located at the micromachine box is connected.The self-locking device that handle connects can be the combination of common lock core of prior art and dead bolt.The scratch type sensor is for having sold product on the market, and it can be 24 core flat wires, and it is connected with DSP module on the computer main board.The scratch type sensor is the semicoductor capacitor sensor, and it is responded to the biological electricity that human epidermal produces, and with the fingerprint amalgamation of its induction, compares with DSP internal memory fingerprint again, therefore can improve safety factor.Handle can be set up respectively on the shell two sides, and can also be provided with emergent lockhole on the shell and be connected with inner lock body.Motor in the micromachine box can connect power supply by power line, and power supply can be made up of the more piece dry cell, perhaps directly connects alternating current by transformer.
As preferably, have window on the described shell, the scratch type sensor places window interior.Window can be that transparent material is made, and it can protect the scratch type sensor not polluted.
As preferably, described transmission mechanism comprises torsion film, and torsion film one end can be touched with switch, and the other end is connected with fan type shifting block on being hinged on lock body, and fan type shifting block is coaxial with handle; Fan type shifting block connects dead bolt by connecting rod, and the torsion film middle part is movably connected on the reference column that is located in the lock body.Torsion film can be other structure that can play leverage, and switch stretches out, the rotation of touching torsion film, and torsion film makes dead bolt open by driving the rotation of fan type shifting block.
As preferably, described fan type shifting block is connected with lock sheet groups, and lock sheet groups is connected with dead bolt by lock core.The fan type shifting block lock sheet groups that can also link, the dead bolt at lock sheet groups place can be 3.
Therefore, it is lower to the utlity model has environmental requirement to external world, and factors such as that finger is done is wet, atmosphere humidity, the temperature difference, high light can be to its influential characteristics; Characteristics such as the utility model also has the static electricity on human body of employing and responds to sensing identification, and recognition speed is very fast, prevents false fingerprint recognition, eliminates safe hidden trouble, and installation volume is less, and is simple and reasonable for structure.
