Specific embodiment

Describe the present invention below with reference to specific embodiment shown in the drawings.But these embodiments are simultaneously The present invention is not limited, structure that one of ordinary skill in the art is made according to these embodiments, method or functionally Conversion is all contained in protection scope of the present invention.

In each diagram of the application, can tie relative to other for the ease of diagram, structure or some partial sizes Structure or part are exaggerated, therefore, it is only used for the basic structure of the theme of diagram the application.

In addition, it is used herein for example " on ", " top ", D score, the term of the representation space relative position such as " lower section " be A unit as shown in the drawings or feature are described for descriptive purpose is easy to relative to another unit or feature Relation.The term of relative space position can be intended to include equipment in use or work in addition to orientation shown in figure not Same orientation.For example, if by figure equipment overturn, be described as being located at other units or feature " lower section " or " under " Unit will be positioned at other units or feature " top ".Therefore, exemplary term " lower section " can include above and below both Orientation.Equipment otherwise can be directed（It is rotated by 90 ° or other directions）, and correspondingly explain it is used herein with it is empty Between related description language.

As shown in figure 1, in the technical solution of the utility model, valve cock plunger tip and O-ring seal are carried out by rubber sheet gasket Integrated design, can realize better seal while jack-up standard tire valve cock inner valve stem is completed.By convex Play plunger tip position side and two passages are set, inside tires have been carried out into UNICOM with the chip part inside sensor unit. Therefore, after the sensor unit in figure is arranged on wheel, the latter half environment and the inside tires environment of element installing space It is completely the same, so as to reach the initial environment condition by sensor core chip centroid measurement wheel tire internal pressure and temperature.Sensing Device part employs metal shell, realizes the inner sealing of sensor by the stepped bayonet socket of shell and sealing；By with The antenna that metal shell is joined directly together realizes the high-gain transmitting of sensor.Antenna Design realizes that highly reliable wireless data is passed Defeated, antenna is joined directly together with sensor metal casing part by equipment by internal pin so that the shell of sensor is direct Become a part for antenna, obtain higher transmitting gain.
