CN2142080Y - Displaying & warning apparatus for monitoring pressure of tyre - Google Patents

Abstract

The utility model relates to a displaying and warning apparatus for monitoring the pressure of a tire. A pressure transducer (1) is arranged on an inflating valve of the tire, and a photoelectric converter (4) which simulates air pressure is arranged on a vehicle body which is near to the tire. Through three light bores, the photoelectric converter is used for picking pulse signals which are converted to electricity from light signals, and the light signals are transferred from a tire pressure sensor to a light-shielding sheet (3) through a flexible shaft drawing wire (2) for displacement and light shielding. Three electric signals are output to a sound, light and display alarm device by the switched data processed by A/D. The utility model can display and alarm to remind drivers to take corresponding measures, so the accident which is caused by the underpressure or the excess pressure of the tires when the vehicle runs at high speed can be avoided.

Description

Displaying & warning apparatus for monitoring pressure of tyre

The utility model relates to a kind of displaying alarm of monitoring tire pressure.

Present all automobiles, the tire of motor bike and various power actuated vehicles, gas leakage for a certain reason, cause the quite a lot of traffic accident, especially the Modern Traffic vehicle such as the untimely discovery tire flat of running at high speed, the air pressure deficiency will cause vehicle body left and right sides overbalance, causing roll-over accident, is very much dangerous.

The purpose of this utility model provides a kind of displaying alarm of monitoring tire pressure, makes the driver in time find the tire pressure mal in the stroke of steering vehicle, takes corresponding measure, avoids accident to take place.

The purpose of this utility model can reach by following measure:

A baroceptor (1) is installed on tire valve, and being loaded on has rubber pneumatic bag (7) or metal bellow in this device, and what head on air bag is pad (8), and the another side of pad is spring (9), feature of the present utility model, and it also comprises:

, a flexible axle backguy (2), it is used for the signal of the pad in the baroceptor (8) displacement is transferred to the outer shade (3) of sensor,

A shade (3), it is used for the signal by the next pad displacement of flexible axle backguy (2) transmission, also makes corresponding displacement, and 1 to 3 unthreaded hole of shading light electric transducer (4) recess promptly blocks D respectively ₄Be sent to D ₁The optical signal of a unthreaded hole, the expression tyre underpressure; Block D ₄Be sent to D ₁And D ₅Be sent to D ₂The optical signal of two unthreaded holes, the expression tire pressure is normal; Block D ₄-D ₁, D ₅-D ₂, D ₆-D ₃The optical signal of three unthreaded holes, expression tire superpressure,

The photoelectric commutator of an analog wheel air pressure (4), it is by D ₄, D ₅, D ₆Three common micro-led and D ₁, D ₂, D ₃Three photodiodes (or using optical transistor) and relevant resistance are formed, and it is installed near on the vehicle body of tire, and it picks up by shade (3) by three unthreaded holes that itself are provided with and carries out the optical signal that displacement is in the light, and is converted to the impulse singla of electricity,

An A/D translation data processing equipment, it is installed in operator's compartment and is used to receive above-mentioned impulse singla, decodes and the A/D conversion, exports three kinds of electric signal then,

Sound, light, displaying alarm (6), it is used to receive three kinds of electric arts that A/D translation data processing equipment (5) transmits number, carries out three kinds of corresponding sound, light, display alarm, reminds the driver to take corresponding measure.

The used shade of the utility model is made by light tight material.

The scheme that the utility model adopted, simple in structure, low price, to automobile, motor bike, and various self-propelled vehiclees travel and can bring very big safety especially body behind the truck to be had four or eight wheels, under steam as certain side have one or two unexpected under-voltage, all the other not under-voltage tires will excessively all have vehicle that the load overvoltage causes blowing out, runs at high speed for heavy duty at any time because of bearing load-carrying pressure, blow out suddenly in travelling so, its consequence very do not imagine.

The utility model is described in further detail below in conjunction with drawings and Examples.
