Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of fingerprint-based padlock comprising lock housing 10, lock rope 20, fingerprint list
Member 30, lock detection unit 40 and locking unit 50.The lock housing 10 includes face-piece 11 and the bottom case being bolted together with face-piece 11
12.The lock rope 20 includes movable end 21 and fixing end 22, and fixing end 22 is fixed by the clamping action of face-piece 11 and bottom case 12
In the lock housing 10.Lockhole (not shown) is additionally provided in the lock housing 10, the movable end 21 of the lock rope 20 is for being inserted into
Into the lockhole, to lock.
It should be noted that the movable end 21 for showing lock rope 20 in Fig. 1 is inserted into two kinds of the lockhole and extraction lockhole
State.The movable end 21 of the lock rope 20 includes the neck 211 of cylindrical type and the head 212 of ball-type, and the diameter on head 212 is big
In the diameter of neck 211, when being inserted into the lockhole in order to the movable end 21 of the lock rope 20, head 212 can be by institute
State the latching of locking unit 50.
The fingerprint unit 30 is set to the bottom in face-piece 11, and whether the fingerprint for being used to detect user matches, when with
When the fingerprint matching at family, the fingerprint unit 30 sends unlock instruction to the locking unit 50.
The lock detection unit 40 is set in face-piece 11 comprising infrared transmitting tube 41, the infrared receiver being oppositely arranged
Pipe 42 and the detection PCB43 being connected with infrared transmitting tube 41, infrared receiving tube 42.When locking, the movable end 21 of lock rope 20
It is inserted into lockhole, the infrared light that infrared transmitting tube 41 is sent is blocked by the movable end 21 of the lock rope 20, and infrared receiving tube 42 can not
Optical signal is received, to detect the state of lockset.Detection PCB43 issues feux rouges and inspection for controlling infrared transmitting tube 41
The state for surveying infrared receiving tube 42, to judge the state of lockset.When the movable end 21 of lock rope 20 blocks infrared light, infrared receiver
Pipe 42 does not receive infrared signal, that is, regards as block signal, and the lock detection unit 40 notifies the locking unit 50 to hold
Row block action.
As shown in Fig. 2, the locking unit 50 includes locking fixing piece 51, brake bars 52, motor 53, lock tongue 54, lock tongue
Spring 55, driving cap 56 and brake bars spring 57.Locking fixing piece 51 is screwed in the bottom of face-piece 11.Lock tongue 54 includes
Guide part 541, locking part 542 and from locking part 542 hollow out formed limiting section 543.Latch bolt spring 55 is mounted on lock tongue
On 54 guide part 541.Driving cap 56 is fixedly mounted on the motor shaft 531 of motor 53, and brake bars spring 57 is sheathed on driving
It on cap 56, drives and a boss 561 is set on cap 56, boss 561 can be as the rotation of driving cap 56 be in the spiral shell of brake bars spring 57
It is rotated in line gap, to drive brake bars spring 57 mobile, brake bars 52 are set on driving cap 56, setting in brake bars 52
There is a vertical slot 571, two terminals up and down of brake bars spring 57 snap onto vertical slot 571, and can be in vertical slot 571 up and down
Sliding.
Brake bars 52, motor 53, brake bars spring 57 and driving cap 56 are assembled into an entirety, are embedded in face-piece 11
Bottom.When the movable end 2 of lock rope 20 is inserted into the gap between lock tongue 54 and locking fixing piece 51, motor 53 is rotated, and makes to make
Dynamic bolt 52 does radial motion and is inserted into the limiting section 543 of lock tongue 54, keeps lock tongue 54 fixed, at this time lock tongue 54 and locking fixing piece 51
The movable end 21 of lock rope 20 is fixed.
The working principle of above-mentioned fingerprint-based padlock is as follows:
As shown in figure 3, the movable end 21 of lock rope 20 pushes lock open when the movable end 21 of lock rope 20 is inserted into the lockhole of lock housing 10
Tongue 54, lock detection unit 40 detects locking, lock signal in transmission, simultaneously because the effect of latch bolt spring 55, keeps lock tongue 54 multiple
Position, motor 53 drives driving cap 56 to rotate clockwise, so that boss 561 drives brake bars spring 57 to move upwards, brake bars bullet
Spring 57 drives brake bars 52 to move upwards, when brake bars spring 57 runs up limit position, even if motor 53 is also rotating,
Since the bottom terminals of brake bars spring 57 snap onto vertical slot 571, so that bottom gap of the boss 561 in brake bars spring 57
Middle skidding will not be further continued for drive and move upwards in brake bars spring 57, will not deviate from the bottom gap of brake bars spring 57.
At this point, brake bars 52 are inserted into the limiting section 543 of lock tongue 54, lock tongue 54 is limited in a hardly movable space,
The fingerprint-based padlock is in " locked state ".
As shown in figure 4, when fingerprint unit 30 collects correct unlocking signal, motor 53 rotates backward in locked state,
Driving cap 56 is driven to reversely rotate, so that brake bars spring 57 drives brake bars 52 to move downward, lock tongue 54 does not have at this time
It is limited by brake bars 52, pulls out the movable end 21 of lock rope 20, push lock tongue 54, the movable end 21 of lock rope 20 is detached from lock
Tongue position is realized and unlocks.Equally, when brake bars spring 57 runs down to limit position, even if motor 53 is also rotating, due to
The top terminal of brake bars spring 57 snaps onto vertical slot 571, so that boss 561 is beaten in the top clearance of brake bars spring 57
It is sliding, drive will not be further continued for and moved downward in brake bars spring 57, the top clearance of brake bars spring 57 will not be deviate from.
In conclusion the fingerprint-based padlock of the utility model is used as locking member using lock rope, the length for locking rope can be selected arbitrarily
It selects, twist bent flexible feature, and lockset is made to have extremely strong convenience and practicability, and the locking particularly suitable for different gun needs
It asks；In addition, due to the structure of the locking unit, so that brake bars, when running to extreme position, timely motor is also rotating,
Brake bars will not be continued up or be moved down, and will not press padlock internal structure, are not present at " dead point ", are hardly damaged padlock
Internal structure.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
