Description
Technical field
The utility model relates to a kind of sensor that can carry out Real-Time Monitoring to automotive tire pressure, is applicable to automotive tyre pressure monitoring field.
Background technology
In the driving process of automobile the running state of tire and the safety of vehicle closely bound up, in the major traffic accidents at home and abroad express highway occurred according to statistics, the ratio that burst is blown out shared by accident, more than 40%, also has a large amount of traffic accidents because air pressure of automobile tire is too high or seepage causes.Just because of this United States Federal by legislation demands car production producer using the standard configuration of system for monitoring pressure in tyre as the automobile that dispatches from the factory, for Real-Time Monitoring tire pressure tire pressure monitoring sensor arises at the historic moment.Tire pressure monitoring sensor as the important composition module in tire pressure monitoring system, work that must be reliable and stable.
Summary of the invention
The purpose of this utility model to provide a kind of monitoring automobile tyre pressure sensor, there is light structure, easy for installation, rationally distributed feature, can Real-Time Monitoring inner tyre pressure, temperature data data wirelessly being sent by radio-frequency transmissions chip.
The technical solution of the utility model is: comprise sensor outer housing; Sensor outer housing is provided with a connection structure, and connection structure is provided with fixed installation hole, and tire tube valve inserts fixed installation aperture tightening screw and is connected with sensor outer housing, is plugged in fixed card slot in connection structure for coordinating the sheetmetal of tightening screw; Sensor outer housing inner chamber is closed with circuit card through sealant, circuit card is integrated with pressure sensor chip, temperature sensor chip, microcontroller, radio-frequency transmissions chip and lithium cell, sensor outer housing has an air extractor vent communicated with the pressure hole on pressure sensor chip.
Pressure sensor chip, temperature sensor chip are connected with the input end of microcontroller respectively, the mouth of microcontroller is connected with radio-frequency transmissions chip, and lithium cell is connected with pressure sensor chip, temperature sensor chip, microcontroller, radio-frequency transmissions chip respectively.
Tire tube valve comprises tire tube valve housing, valve inside, rubber coating, valve cap.
Described tire tube valve housing is made up of aluminum alloy materials.
The utility model is considered and the comfort feature that sensor assembles and stability sensor shell is designed with a narrow fixed card slot, and tire tube valve is fixed together by a sheetmetal and tightening screw and sensor outer housing.Have a minute ventilation above sensor outer housing to be convenient to pressure sensor to communicate with the air pressure environment of inside tires in the position corresponding with circuit card upward pressure sensor pressure hole, make result of a measurement more accurate.Circuit card is the nucleus module of this tyre pressure sensor, it is integrated with pressure, temperature sensor chip, microcontroller chip, lithium cell and radio-frequency transmissions chip.Wherein microcontroller can the data-signal that collects of processing pressure, temperature sensor in real time as main control chip, and result is wirelessly launched by radio-frequency transmissions chip.In order to save material and better sealing property sensor outer housing do not adopt traditional upper lower casing fit form, but adopt open architecture bottom sensor outer housing, circuit card and sensor outer housing seal by final utilization industry special seal gum.
