Description
Technical field
The present invention relates to vehicle electric field, particularly relate to a kind of TPMS system that is installed in the motor tire.
Background technology
Tire is the important component part of automobile chassis, and as important supporting member and walking element, tire is not only carrying the all-mass of automobile, and also will advance to automobile provides propulsive force, plays the effect that relaxes ground shock simultaneously.Tire all plays a part very crucial to the economy of road-holding property, ride comfort, safety, traveling comfort and the fuel oil of automobile.
In order to guarantee vehicle safety travel, current now method is at automobile air pressure of automobile tire monitoring system (TPMS) to be installed, monitor the parameters such as air pressure of tire in real time, for the low tire pressure that causes because of tire flat, and Yin Gaowen, high tire pressure and easily produce the situation of blowing out, with visual signal or can comprise that also audible signal shows and reports to the police.Running safety can be improved like this, and the energy consumption because of the not enough tire accelerated wear test that causes of air pressure and reduction vehicle can be reduced.
Existing TPMS sensor is installed the mode that adopts the integrated tire tube valve of TPMS sensor to fix by tire tube valve and wheel hub then, and there is the following defective in such mounting means:
One, different automotive hubs require to have different tire tube valves to adapt to, and the TPMS system sensor all needs exploitation separately at different tire tube valves like this, has increased cost of development, and the component part of product has also increased the tire tube valve cost simultaneously;
Two, existing TPMS utilizes integrated tire tube valve as the RF antenna, and the resistance difference of tire tube valve brings certain degree of difficulty to the network coupling of circuit high frequency;
Three, integrated tire tube valve has increased the weight of TPMS sensor, is unfavorable for developing to little, the in light weight direction of volume of sensor;
Four, existing TPMS sensor is integrated, and tire tube valve is fixed on the wheel hub as a part, and tire tube valve is exposed to outside the tire, makes sensor be subjected to the influence of some harsies environment such as water spray of ESD, rubble, High Temperature High Pressure through regular meeting;
Five, the fragile sensor of tire dismantling.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can adapt to various wheels, and antijamming capability is strong, and it is little to be affected by the external environment, and dismantles non-damageable TPMS system.
For solving the problems of the technologies described above TPMS of the present invention system, comprising:
The tyre pressure sensor module is installed in the motor tire, for detection of temperature, the pressure of tire, and sends the information that detects to the tire pressure monitor scope;
The tire pressure monitor scope is installed in the operator's compartment, is used for receiving the information of tyre pressure sensor module, monitors also temperature, the pressure of display of tyre;
Described tyre pressure sensor module comprises:
