Abstract
The invention provides an identification key of a radio-frequency antenna, belonging to the field of daily electronic equipment. A radio-frequency circuit is arranged in a main structure of the key; the circuit breakover part of the radio-frequency circuit comprises at least two components; and a pressure switch structure that can be used for controlling the breakover state of the radio-frequency circuit through the pressure is arranged between the components, thereby effectively avoiding the detection of an external detector for the information on a user RFID and preventing the information outleakage of a user and other safety problems. Meanwhile, with the adoption of the identification key of the radio-frequency antenna, the identification function of the radio-frequency antenna can be realized when the user comes into the room, so as to reduce the inconvenience caused by different inner disks of the key when in key bitting. A clamping layer arranged on the key can avoid the phenomenon that a key-bar inner disk is separated from a key bar due to the inappropriate usage of the identification key of the radio-frequency antenna.
Description
Technical field
The invention belongs to daily electronic device field.
Background technology
RFID is the abbreviation of Radio Frequency Identification, and promptly radio-frequency (RF) identification is commonly called as electronic tag.Data are write in the RFID chip, when the RFID chip is put into inside, magnetic field,, just can will deposit the data read in the RFID chip in, and effectively discern by corresponding data reading system.
At present, can under rugged surroundings, work and advantage such as price material benefit is subjected to pursuing of people deeply, use very extensive because of the RFID technology.Yet, existing RFID device, not enough to the protection of its data,, as long as the RFID device is in inside, corresponding magnetic field, just can be by any data reading system reading of data, thus cause many unsafe factors to people's life, study, amusement etc.
In order to improve the problems referred to above, in recent years, many solutions have been proposed, for example, Chinese patent (application number) cn200510087941 has proposed a kind of portable memory with function of keeping secret, in the present invention, reader is installed on the portable memory, then an electric label is positioned on its separable outer box or on a kind of portable article, the principle mode of utilizing RFID to read electric label is come that portable memory is carried out data and saved action from damage.Current research mainly concentrates on the data confidentiality field, in this field of data protection, also needs further to strengthen its safeguard measure.
In view of the above-mentioned state of the art, the present invention proposes a kind of identification key of radio-frequency antenna, avoided the detection of outer locator effectively to information on the user RFID, and the information that prevents user safety problem such as leak outside.
Summary of the invention
The purpose of this invention is to provide a kind of identification key of radio-frequency antenna.
It is set that a kind of identification key of radio-frequency antenna, its correspondence the shank of the key, key bar and key bar inner core, it is characterized in that:
In the key agent structure, be provided with radio circuit;
The circuit turn-on part of described radio circuit comprises two assemblies at least;
Between described assembly, be provided with the pressure switch construction of controlling aforesaid radio circuit conducting state by pressure.
Further, described a kind of identification key of radio-frequency antenna also has following technical characterictic:
Described key bar is realized the externally main element of induction as a kind of identification key of radio-frequency antenna, fixedlys connected by inboard with key handle.
Described key bar inner core is provided with the functional module of radio circuit.
Described radio circuit, it is arranged on the key bar inner core, has the assembly of radio frequency recognition function.
Described radio circuit, it includes RFID chip, RFID antenna and RFID antenna conductive junction point.
Outer setting at described key bar inner core has the holding layer, and on this holding layer, corresponding radio circuit is provided with position limiting structure.
Corresponding described key bar inner core and radio circuit are provided with the pressure switch of controlling aforesaid radio circuit conducting state by pressure.
The invention has the advantages that:
Be replicated easily at existing RFID recognition function, unsafe phenomenon, identification key of radio-frequency antenna of the present invention utilizes the pressure switch on it, when the user opens the door step, pressure switch does not produce closing phenomenon, and the radio circuit assembly does not constitute conducting, and RFID sends with regard to externally not carrying out signal, so just can prevent the detection of outer locator effectively, the information that prevents the user effectively safety problem such as leak outside to information on the user RFID; When the user need enter house interior,, make the pressure switch closure by ambient pressure, the conducting of radio circuit assembly, the radio circuit assembly externally sends signal, just can carry out data with the RFID detector of porch, room and be connected, and the user just can enter house interior like this.Simultaneously, utilize identification key of radio-frequency antenna of the present invention, can when the user enters the room, realize the radio-frequency antenna recognition function, join the inconvenience that different key inner cores bring when getting key thereby reduce people.Can avoid using identification key of radio-frequency antenna improper and be arranged on this holding layer on the key, cause the key bar inner core to break away from the phenomenon of key bar because of the user.
