Radio frequency identification key-100; Key bar-200, key bar inner core-210, screen layer-220, screen layer position limiting structure-230, elastic construction-240, RFID firmware-250, cavity body-260; Key handle-300.
Detailed description of the invention
The explanation of Fig. 1:
Shown in ginseng Fig. 1, illustrate a kind of primary structure of radio frequency identification key 100, this system 100 mainly includes following structure:
Key bar 200, is realized the main element of externally induction, is fixedly connected with key handle 300 by inner side as a kind of like this radio frequency identification key 100.
Key bar inner core 210, it is the agent structure of key bar 200, is provided with the functional unit of radio frequency identification.
Screen layer 220, it is enclosed within the electromagnetic armouring structure on key bar inner core 210.
Screen layer position limiting structure 230, it is positioned on key bar inner core 210, arranges respectively in screen layer 220 front-end and back-end.
RFID firmware 250, it is arranged on key bar inner core 210, has the assembly of radio frequency recognition function.
For example and without limitation, RFID firmware 250 is arranged on key bar inner core 210, correspond to described key bar inner core 210, it is also provided with the screen layer 220 of tubulose, screen layer 220 is set to metal construction, scribble the structure of metal material and three's at least one in the network that is made up of metal fine.Screen layer 220 moves around by user as required on key bar inner core 210.The screen layer position limiting structure 230 for preventing screen layer 220 from dropping from key bar inner core 210 is respectively arranged with in the front-end and back-end of screen layer 220.
When using radio frequency identification key 100, as shown in Figure 2, screen layer 220 structure be positioned on key bar inner core 210 is placed on RFID firmware 250, and by the shielding of screen layer 220 structure, the information on RFID firmware 250 cannot be detected by external equipment.And when entering designated room, as shown in Figure 1, only need the screen layer 220 be coated on RFID firmware 250 to remove, screen layer 220 just effectively can not shield RFID, just can enter designated room.The screen layer position limiting structure 230 being positioned at screen layer 220 front-end and back-end also can the excessive movement that causes when mobile screen layer 220 of limited subscriber make mobile screen layer 220 depart from key bar inner core 210.
The explanation of Fig. 3:
Shown in ginseng Fig. 3, illustrate a kind of another kind of embodiment of radio frequency identification key 100, this its structure of system 100 is basic similar with a upper embodiment, is also be provided with in the structure of this embodiment:
Elastic construction 240, correspond to screen layer 220 and key bar inner core 210 and is provided with the screen layer that elastic construction 240 realizes and restores assembly.
Described elastic construction 240 is set to spring assembly, and this elastic construction 240 one end is connected with screen layer 220, and the other end is connected with the position of key bar inner core 210 near key handle 300.
The screen layer position limiting structure 230 for preventing screen layer 220 from dropping from key bar inner core 210 is provided with in the front end of screen layer 220.
For example and without limitation, when entering designated room, hand-held key handle 300 end, close to the detection system of designated room, external detection equipment elasticity of compression structure 240, moved to key bar inner core 210 rear end by the screen layer 220 be placed on RFID firmware 250, screen layer 220 effectively can not shield RFID.Now, detection system just can identify RFID information, and like this, user just can enter designated room.Work as end of identification, draw back key handle 300, screen layer 220 is back to the position before enabling by the active force appliance for releasing single of elastic construction 240, so again can to the information realization shield effectiveness on RFID firmware 250.
The explanation of Fig. 4:
Shown in ginseng Fig. 4, illustrate the third embodiment of a kind of radio frequency identification key 100, this its structure of system 100 is basic and previous embodiment is similar, is also be provided with in the structure of this embodiment:
Described key bar inner core 210 is channel-shaped structure or hollow structure, in the rear end of its channel-shaped structure or hollow structure, arrange such elastic construction 240, this elastic construction 240 is connected with screen layer 220, and in the orientation of key bar inner core 210 near key handle 300, outlet is set.
Cavity body 260, it is the channel-shaped structure or the hollow structure that are arranged at key bar inner core 210.
For example and without limitation, when entering designated room, hand-held key handle 300 end, close to the detection system of designated room, external detection equipment elasticity of compression structure 240, moved to key bar inner core 210 rear end by the screen layer 220 be placed on RFID firmware 250, screen layer 220 effectively can not shield RFID.Now, detection system just can identify RFID information, and like this, user just can enter designated room.Work as end of identification, draw back key handle 300, screen layer 220 is back to the position before enabling by the active force appliance for releasing single of elastic construction 240, so again can to the information realization shield effectiveness on RFID firmware 250.
Be more than the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
