Description
Technical field
The present invention relates to the sensor package structure, especially sensor and antenna are packaged in and have conductivity, in the dielectric materials, also relate to the dielectric rubber bodies of making this sensor package.
Background technology
A kind of magnetic detector that has for detection of the magnetoresistive element of magnetic resistance is arranged in the prior art, and a kind of holding circuit of being formed by a plurality of electronic units.The electronic installation that sensor and tire are combined, can be in the process of making, selling and using identification and the function of following the tracks of.The usage period measurements that these electronic installations can be used in tire is the physical parameter of temperature and pressure for example.Many systems have utilized the radio-frequency communication between tire and outer monitoring and the inquiry unit.
There are some to be installed to tire or wheel surface in the prior art or are combined in system in the inflation of tire valve.Expect to have kind of device and be directly connected to surface of tyre or be embedded in antenna in the tire construction, as permanent integration of putting concussion.Yet tire directly embeds in the tire and has difficulties.
Radio-frequency (RF) energy is propagated by antenna, and antenna must be by the elastomer material that is generally used for constituting tire on every side, and still this material normally conducts electricity, and the higher specific inductivity that compares is arranged.The conductive dielectric materials that has that contacts with antenna allows radio-frequency current to pass through between the adjoint point of antenna, therefore will realize this transmission by suitable dielectric and reactance.
When embedding at last or otherwise antenna being arranged to directly to contact with tire, also can have influence on original physicals, so antenna and inductor block must adhere on the elastomeric material to guarantee the location.In addition, the antenna carrier material must bear the operating cyclic stress of tire.
Summary of the invention
The object of the present invention is to provide a kind of elastomeric material with conductivity and specific electrical resistance for encapsulated sensor and radio-frequency antenna, and this structure that conductive specific electrical resistance material package sensor is arranged.The present invention is transmitted effective especially in rubber bodies for wireless, and improves the sensor package effect.
Technical scheme of the present invention is: a kind of dielectric rubber bodies of encapsulated sensor, and the prescription of described dielectric rubber bodies is as follows:
Preferably: described tire radio communication system is arranged on the surface of inboard of tire, described tire radio communication system comprises encapsulating structure and is positioned at the Ridio communications device of encapsulating structure inside, described encapsulating structure is the dielectric rubber bodies, and described Ridio communications device embeds the dielectric rubber bodies.
Preferably: described Ridio communications device comprises the sensed data device and is fixed in the antenna at sensed data device two ends that the head of described sensed data device is exposed to the outside of dielectric rubber bodies.
Preferably: the bottom margin of described sensed data device and dielectric rubber bodies rigidity are bonding.
Beneficial effect of the present invention is: the present invention is the conductivity radio-frequency unit in tire, device comprise multiple component units and antenna can be in making, sell and using the track record data, the scope of mensuration comprises temperature, pressure or other physical parameters in the tire.In the sensor loading process, conductive of material in the selection invention, has certain specific inductivity and sticking power, what make that device not only can be firm is connected with tire and transmission data that can be more stable, snappiness and the good mechanical performance of rubber can well be born the stress that tire cyclomorphosis brings simultaneously.This structure Design not only can load on the tire body more easily, and lighter, so that this small and exquisite sensor construction can be accepted and adopt to littler tire body.
