The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to Fig. 1, the control circuit board 1 that is provided with pressure inductor is encapsulated in the shell 2, described pressure inductor sealing shroud is equipped with the air bag 4 that is provided with socket 4.1, the extension rod 3 of described threeway is respectively equipped with air bag interface 3.1, tire valve interface 3.2 and extension rod tire tube valve 3.3, and described air bag interface 3.1 passes shell 2 and is connected with socket 4.1 on the air bag 4.Described shell 2 is divided into upper and lower casing 2.2,2.1, described upper shell 2.2 is not for influencing the insulating material of signal transmission, described lower house 2.1 is a silica gel material, be that control circuit board 1 is packed into behind the upper shell 2.2, the recycle silicon glue material encapsulates upper shell 2.2 by the encapsulating technology and forms lower house 2.1, and is connected as a single entity with upper shell 2.2.Described shell 2 can be affixed by thread-forming screw 5.1 with support 5.Described support 5 is by being connected with wheel hub with wheel bolt with the equidistant circular hole of wheel hub.
With reference to Fig. 2, the utility model tire pressure wireless sensing device 12 is installed on the front-wheel hub 6, concrete grammar is: the tire valve on the extension rod 3 3.2 is connected with the tire tube valve 7 of front tyre 8, air pressure in the tire is introduced air bag 4,3.3 original functions that replace tire tube valve 7 on the front tyre 8 of extension rod tire tube valve on the extension rod 3 are used for venting or inflation etc. in front tyre 8.Support 5 places on the front-wheel hub 6, is fixed on the vehicle bridge simultaneously by wheel bolt with wheel hub.
Principle of work: by the connection of extension rod 3, the air pressure in the air bag 4 and the tire pressure of tire are consistent, the pressure that pressure sensor in the air bag 4 can accurately record in the air bag 4 changes, control circuit board 1 is transmitted to the receiving and displaying device in the operator's compartment after can the signal conditioning with the pressure sensor collection, promptly and accurately understands tire pressure varies to help chaufeur.The shell 2 of encapsulation control circuit board 1 has adopted the method for encapsulating to seal, can actv. protection control circuit board 1 and on pressure sensor and air bag 4, solved that pressure sensor is waterproof and dampproof when external, sealing problems such as antagonism inclement weather and road conditions.Thereby described pressure sensor is to change barrier film by pressure to produce the arm resistance also and then principle gaging pressure of the concurrent deformation variation of deformation at the electric bridge of membrane surface, as selects the pressure sensor of the NPP301A model of GE company production.The circuit theory of described control circuit board 1 is measured with the control circuit board principle identical with existing inner tube free manned vehicle tire pressure.Can also add temperature sensor and acceleration pick-up on the control circuit board 1, so that further monitor temperature and acceleration/accel in the tire.
With reference to Fig. 3, Fig. 4, Fig. 5, in like manner, the utility model can also be installed on the commercial vehicle/comm..vehicle rear wheel hub, because the commercial vehicle/comm..vehicle trailing wheel mostly is twins, inside and outside tire 9,10 dos-s of trailing wheel, therefore need on rear wheel hub 11, two tire pressure wireless sensing devices 12 be installed symmetrically and evenly, extension rod 3 can be done suitably distortion so that connect the tire tube valve of the inside and outside tire 9,10 of corresponding trailing wheel with two tire valve mouth opposite positions.
