Description
Technical field
The present invention relates to automotive safety accessory field, more particularly to a kind of external can inflation/deflation tyre pressure sensor.
Background technology
There is data to suggest that, the shared ratio in pernicious vehicle accident of the traffic accident caused by blowing out is very high, and all meetings
Tire pressure deficiency in the factor that blows out is caused to work as first cause.This is not to deliberately exaggerate so as to create a sensation, even if you do not select to supervise with tire pressure
The vehicle of survey, will also improve the attention to vehicle tyre, it is to avoid people and Che occur serious damage.
The contact area of tire and ground when tire pressure is too high, can be reduced, and the now pressure born by tire is carried relatively
Height, the earth-grasping force of tire can be affected.In addition, when vehicle through ditch or jolt road surface when, without sufficient space in tire
Vibrations are absorbed, in addition to the stability of impact traveling and riding comfort, can also cause to put more effort the impact of suspension,
Thus harm is also brought along.Meanwhile, the hidden danger that blows out in high temperature can also be accordingly increased.
Tire pressure monitoring is broadly divided into two kinds, and one kind is indirect type tire pressure monitoring（Wheel-Speed Based TPMS, referred to as
WSB）, another kind is direct-type tire pressure monitoring（Pressure-Sensor Based TPMS, abbreviation PSB）.Direct-type tire pressure is supervised
It is come the air pressure of direct measurement tire, using wireless transmitter using the pressure transducer on each tire to survey device
Pressure information is sent in central receiver module from inside tires, then each tire pressure information is shown.Work as wheel
Air pressure is too low or during gas leakage, system can automatic alarm.The current tyre pressure sensor of direct-type tire pressure monitoring is mainly divided to two kinds：A kind of
It is built-in tyre pressure sensor；Another kind is external tyre pressure sensor.Both operation principles are the same, are all by pressure
Sensor carrys out direct measurement tire pressure, differs primarily in that therebetween the mounting means of pressure transducer is different.External
The maximum advantage of tyre pressure sensor is simple installation, as gas nozzle cap quilt " twisting " to above cranked tire valve, can DIY independently pacify
Dress, shortcoming are exactly that each inflation/deflation needs removal sensor；Built-in tyre pressure sensor needs to be attached to inside tires, it is necessary to arrive
The repair shop that tire can be dismounted is operated, and may be also needed to change original valve, will also be done to tire after installing
Balance, installation process are complicated.The operation principle of indirect type tire pressure monitoring is:When the air pressure of certain tire reduces, the weight of vehicle
The rolling radius of the wheel can be made to diminish, cause its rotating ratio other wheels fast.By the rotating speed difference between comparative tire, with
Reach the purpose of monitoring tire pressure.Indirect type tire warning system is actually carried out to air pressure by tire rolling radius is calculated
Monitoring.
Chinese utility model patent number is：" ZL201320523431.7 ", patent name is：" the two-way tire of integrated direct-type
Disclose in the patent document of the smart entry system of pressure monitoring function "：" a kind of integrated direct-type bidirectional tyre pressure monitoring function
Smart entry system, enters controller, display module, tire pressure monitoring triggering antenna and tire pressure monitoring sensor including intelligence；Aobvious
Show that module enters controller by CAN and intelligence and is connected；Tire pressure monitoring triggering antenna is arranged at vehicle body and enters control with intelligence
Device electrical connection processed, tire pressure monitoring sensor are respectively arranged in tire.But ", this tyre pressure sensor needs to take in inflation
Get off, reinstalled after charging gas again, so loaded and unloaded back and forth, be just easy to damage sensor and be easily caused gas leakage.
