Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under The utility model is further described in face.

Intelligent padlock shown in Figure 1, including lock housing 100, locking bar 200, lock tongue 300, memorial alloy driving unit 400.Locking bar 200 in the present embodiment is U-shaped bar, and one end 201 of locking bar 200 is floated by elastomeric element 210 to be arranged in lock housing On 100, the other end 202 of locking bar 200 has locked groove 220 corresponding with the first end 301 of lock tongue 300.In order to enable locking bar 200 It is formed between lock tongue 300 and easily goes out structure into hardly possible, 301 upper surface of first end of lock tongue 300 is set as bevel structure 310.Lock tongue 300 second end 302 is connect with memorial alloy driving unit 400, and the effect of memorial alloy driving unit 400 is driving lock tongue 300 move back and forth.

Memorial alloy driving unit 400 in the present embodiment includes the driving circuit circuit with memory alloy wire 410 420, the memory alloy wire 410 in driving circuit circuit 420 is connect with the second end 302 of lock tongue 300, is connected for convenience, lock tongue 300 second end 302 is provided with the positive stop lug boss 302a connecting with memory alloy wire 410, facilitates and drives lock tongue 300 mobile.

Microswitch 430 corresponding with the second end 302 of lock tongue 300, lock tongue are additionally provided in driving circuit circuit 420 300 second end 302 is also connect with a return springs 440.The power drives mode in driving circuit circuit 420 is button driving Either password driving or wireless telecommunications driving.Button driving or password driving or wireless telecommunications are driven to existing unlocking Conventional means, such as when Password Input is correct, power switch will be triggered；Or between mobile phone and electric power driving module Power switch will be triggered when reaching presetting connection relationship.Above-mentioned this technology is commonly utilized in hotel's door lock, household Door lock.

An anti-lost unit mould corresponding with the mobile phone end of user is additionally provided in lock housing 100 in the present embodiment Block 500, anti-lost unit module 500 include bluetooth module 510 corresponding with the mobile phone end of user and buzzer 520, when bluetooth module 510 is more than pre-set value at a distance from mobile phone end, buzzer 520 can sound the alarm, and play Anti-lost effect.

It is provided with reel 421 in driving circuit circuit 420 in the present embodiment, enables driving circuit circuit 420 Reasonable coiling.

The working principle of the utility model is as follows:

When needing to unlock, by realizing that driving circuit circuit 420 is connected in the power drives mode preset, at this time Driving circuit circuit 420 have electric current by conducting, memory alloy wire 410 at this time can obtain a moment warming temperature, make It obtains memory alloy wire 410 to reach phase transition temperature and shorten, and then drives the second end 302 of lock tongue 300 to separate first end 301 Direction movement, so that the first end 301 of lock tongue 300 is deviate from locked groove 220, locking bar 200 is another under the action of elastomeric element 210 Lock housing 100 is stretched out in one end 202, realizes and unlocks；And the second end 302 of lock tongue 300 can be touched when moving to certain distance it is micro- Dynamic switch 430, so that driving circuit circuit 420 powers off, memory alloy wire 410 restores raw footage, in the work of return springs 440 It is restored to original position with the first end 301 of lower lock tongue 300, waits locking movement.

When needing to lock, it is only necessary to overcome the active force in elastomeric element 210 with external force, that is, may make locking bar 200 The other end 202 carries out pressing action to the first end 301 of lock tongue 300, the active force of return springs 440 is overcome, when lock tongue 300 First end 301 be directed at locked groove 220 after, under the active force of return springs 440, the first end 301 of lock tongue 300 is inserted into locked groove 220, complete locking movement.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
