Description
Technical field
The present invention relates to automotive safety accessory field, particularly relate to a kind of external can inflation/deflation tyre pressure sensor.
Background technology
Have data to show, the ratio of the traffic accident caused by blowing out shared by pernicious traffic accident is very high, and all meetings cause tire pressure deficiency in the factor of blowing out to work as first cause.This is not deliberately exaggerate so as to create a sensation, even if you do not select the vehicle with tire pressure monitoring, will improve the attention to vehicle tyre yet, avoid people and Che that serious damage occurs.
When tire pressure is too high, can reduce the area of contact on tire and ground, and the pressure that now tire bears improves relatively, the earth-grasping force of tire can be affected.In addition, when vehicle is through ditch or road surface of jolting, in tire, there is no sufficient space absorbing vibration, except impact travel stability and travelling comfort except, also can cause and the impact of suspension is put more effort, also can bring harm thus.Meanwhile, the hidden danger of blowing out when high temperature also can increase accordingly.
Tire pressure monitoring is mainly divided into two kinds, and one is indirect type tire pressure monitoring (Wheel-Speed Based TPMS is called for short WSB), and another kind is direct-type tire pressure monitoring (Pressure-Sensor Based TPMS is called for short PSB).Direct-type device for monitoring tyre pressure is the air pressure utilizing the pressure sensor be arranged on each tire directly to measure tire, utilize wireless launcher to be sent to central receiver module by pressure information from inside tires, then each tire pressure information is shown.When tire pressure is too low or leak gas, system can automatic alarm.The current tyre pressure sensor of direct-type tire pressure monitoring mainly divides two kinds: one is built-in tyre pressure sensor; Another kind is external tyre pressure sensor.Both principle of work are the same, are all carry out direct measuring pulley air pressure by pressure sensor, and the key distinction is that the mounting means of pressure sensor is different therebetween.The maximum advantage of external tyre pressure sensor is simple installation, and as gas nozzle cap, quilt " is twisted " above cranked tire valve, can independently install by DIY, and shortcoming is exactly that each inflation/deflation needs removal sensor; Built-in tyre pressure sensor needs to install to inside tires, must arrive and can the repair shop of dismounting tire operate, also may need to change original valve, also will do kinetic balance to tire after installing, and installation process is complicated.The principle of work of indirect type tire pressure monitoring is: when the air pressure of certain tire reduces, the weight of vehicle can make this theoretical running radius of tire of taking turns diminish, and causes other wheels of its revolution ratio fast.By the rotating speed difference between comparative tire, to reach the object monitoring tire pressure.Indirect type tire warning is actually and relies on calculating tire rolling radius to monitor air pressure.
Chinese utility model patent number is: " ZL201320523431.7 ", patent name is: disclose in the patent document of " smart entry system of integrated direct-type bidirectional tyre pressure monitoring function ": " a kind of smart entry system of integrated direct-type bidirectional tyre pressure monitoring function, comprises intelligence and enters controller, display module, tire pressure monitoring trigger antenna and tire pressure monitoring sensor; Display module enters controller by CAN and intelligence and is connected; Tire pressure monitoring trigger antenna is arranged at vehicle body and enters controller with intelligence and be electrically connected, and tire pressure monitoring sensor is arranged in tire respectively.But ", this tyre pressure sensor needs when inflating to take off, and reinstalls again, load and unload so back and forth after charging gas, is just easy to damage sensor and easily causes gas leakage.
