The explanation of Fig. 5:
Shown in ginseng Fig. 5, showed the primary structure of a kind of radio frequency guide-passage key, lock cylinder system 100 here, these system's 100 principal characters are as follows:
Radio frequency guide-passage key 200 mainly is made up of key bar 210 and key handle 250.Described key bar 210 is fixedlyed connected by inboard with key handle 250.Be provided with on the key bar 210 and have non-conduction circuit 220 structures of individual radio-frequency information, radio frequency chip 240 with personal information is set on non-conduction circuit 220 structures, corresponding described radio frequency chip 240 is provided with the key tie point 230 that is connected in order to extraneous conductor.As shown in Figure 5, in radio frequency chip 240 lower ends, utilize conducting structure, be respectively arranged with key first tie point 231, key second tie point 232, these two tie points do not constitute conducting structure, and first tie point 231 is annulus, and key second tie point 232 is the point in the annulus.
Corresponding radio frequency guide-passage key 200, on radio frequency guide-passage lock core 300, be provided with can with the lock core guide passage of the corresponding realization conducting of the circuit on the radio frequency guide-passage key 200.The lock core guide passage is provided with and key tie point 230 corresponding lock core guide passage tie points.Lock core guide passage first tie point, lock core guide passage second tie point are set on the lock core guide passage.The elastic device that lock core guide passage tie point front end can be upspring is set in the radio frequency guide-passage rear end, and the elastic device here adopts spring or flexure strip structure to implement.
For example and without limitation, a kind of radio frequency guide-passage key, lock cylinder system 100 are achieved in that as Fig. 5, utilize the non-conduction circuit 220 on the radio frequency guide-passage key 200, elastic device on the lock core guide passage can be upspring the front end of lock core guide passage tie point 320, radio frequency guide-passage does not constitute conducting structure, this moment, radio-frequency information did not externally send, and just effectively prevented the detection of outer locator to information, the information that prevents user safety problem such as leak outside.
In the time of need entering designated room, radio frequency guide-passage key 200 is inserted radio frequency guide-passage lock core 300 inside, elastic device is compressed.This time, the key tie point 230 that is connected with radio frequency chip 240 is connected with the lock core guide passage tie point that is arranged at lock core inside, be that key first tie point 231 is conducted with lock core guide passage first tie point, key second tie point and the first tie point conducting of lock core guide passage, under whole key tie point 230 and the contacted situation of lock core guide passage tie point, the circuit turn-on on the radio frequency guide-passage key.Radio frequency chip 240 just externally sends signal like this, carries out data with the radio-frequency probe of entrance, room and is connected, and the user also just can enter the room.
That is to say that described lock core guide passage tie point 320 is provided with respectively for the both sides on the key main body at key tie point 320 under one the situation, equally also respectively establish corresponding position and respectively establish lock core guide passage tie point in the position of correspondence,
First tie point at described key tie point 320 is an annulus, and key second tie point is the point in the annulus, and pairing lock core guide passage tie point is the point in annulus and the annulus.
The implementation method of radio frequency guide-passage key, lock cylinder system, this method includes following steps:
Step 1 is made radio frequency guide-passage key 200, and supporting radio frequency guide-passage lock core 300.
Radio frequency guide-passage key 200 mainly is made up of key bar 210 and key handle 250.Described key bar 210 is fixedlyed connected by inboard with key handle 250.Setting has non-conduction circuit 220 structures of radio-frequency information on the key bar 210, and radio frequency chip 240 is set thereon.Simultaneously, corresponding radio frequency chip 240 is provided with the key tie point 230 in order to be connected with extraneous conductor.
Further, on radio frequency guide-passage lock core 300, being provided with can be corresponding with the circuit on the radio frequency guide-passage key 200 and realize the lock core guide passage 310 of conducting, as the conductor part of non-conduction circuit 220 disappearances on the radio frequency guide-passage key 200.Simultaneously, corresponding non-conduction circuit 220 is provided with and key tie point 230 corresponding lock core guide passage tie points 320 on the lock core guide passage 310.Lock core guide passage 310 is provided with lock core guide passage first tie point 321, lock core guide passage second tie point 322.Corresponding described lock core guide passage tie point 320 is provided with the elastic device 330 that lock core guide passage tie point 320 front ends can be upspring in radio frequency guide-passage 310 rear ends.
Step 2 is inserted into radio frequency guide-passage key 200 in the radio frequency guide-passage lock core 300.
When entering designated room, radio frequency guide-passage key 200 is inserted radio frequency guide-passage lock cores 300 inside, the elastic device 330 on the lock core guide passage 310 is compressed, and the front end of lock core guide passage tie point 320 is compressed to and radio frequency guide-passage lock core 300 inboard parallel positions.
Step 3, lock core guide passage tie point 320 in the radio frequency guide-passage lock core 300 and the key tie point 230 on the radio frequency guide-passage key 200 contact and are in the state of conducting.
At this moment, key tie point 230 is connected with the lock core guide passage tie point 320 that is arranged at lock core inside, and promptly key first tie point 231 is conducted with lock core guide passage first tie point 321, key second tie point 232 and 322 conductings of lock core guide passage first tie point.
To conducting state, supporting identification data can take place in radio frequency chip 240 by not on-state for step 4, the integrated circuit of the radio frequency chip 240 on the radio frequency guide-passage key 200.
Under whole key tie point 230 and lock core guide passage tie point 320 contacted situations, form turning circuit on the radio frequency guide-passage key.Radio circuit externally sends signal like this, carries out data with the radio-frequency probe of entrance, room and is connected, and the user also just can enter the room.
More than be the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
