Abstract
The utility model discloses an external pressure monitoring devices in tire has solved because the external atmospheric pressure of tire changes, and safe tire pressure value can not be along with the change, and lead to blow out or suppress the problem that the child was travel, it mainly constitutes an overall structure by inflating valve, outside pressure sensor and inboard pressure sensor. Outside pressure sensor is located the valve inside outside, fixes at the dust cap to with external gaseous contact, inboard pressure sensor is located the inflating valve base, be located the tire inside, with tire intrinsic qi physical contact. The utility model discloses an install two sensors in the outside in the tire, respectively interior the and outer atmospheric pressure of child of real -time supervision child to give a pressure correction value, the degree of accuracy of the safe tire pressure value ensureing to show, messenger's tire can not excessive pressure or under -voltage, provides reliable guarantee for traveling.
Description
Technical field
This utility model is related to automotive tyre pressure monitoring, and especially one kind can change with ambient pressure and change safety tyre pressure value
Tire in external pressure monitoring device.
Background technology
Current automotive tyre pressure monitoring is pressure transducer to be installed on the inside of valve inside in tire and data are reached into automobile
Tire pressure monitoring system, can be with the pressure in real-time detection tire.When pressure is less than safety tyre pressure value, automobile instrument panel reminds pressure
Deficiency, needs inflation with supplementary pressure；When causing in tire pressure rise and be more than safety tyre pressure value because temperature rises the reason such as high
When, instrument reminds pressure excessive, now can deflate to reduce pressure in tire.
It is a normal atmosphere that this pressure detection method is acquiescence tire external pressure, and have ignored external environment change and lead
The change of tire external pressure is caused, such as with the rising of height above sea level, air pressure is reduced, and tire external pressure is less than a normal atmosphere, now instrument
Table may show that pressure is more than safety tyre pressure value in tire, and such case is instrument false alarm, easily cause erroneous judgement and grasp by mistake
Make（Such as deflate decompression）.
And when tire external pressure is more than normal atmosphere, now show that pressure is less than safety tyre pressure value, instrument meeting again in tire
False alarm, causes erroneous judgement and maloperation（Such as plenum）, it is easily caused the accident such as blow out.
The content of the invention
In order to solve above-mentioned technical problem, this utility model provides external pressure monitoring device in a kind of tire, by being arranged on
Two sensors in outside in tire, monitor respectively in tire and the outer air pressure of tire, so as to give a pressure correction value, it is ensured that show
Tire pressure value accuracy, provides for traveling and reliably ensures.
The technical scheme in the invention for solving the technical problem is：
External pressure monitoring device in a kind of tire, by valve cock, outside pressure sensor and inside pressure sensor group into one
Individual overall structure.
The valve cock is made up of valve cock pedestal, fastening nut, liner, dust cap and valve inside.
The outside pressure sensor is located at valve inside outside, is fixed on dust cap, and contacts with ambient atmos.
The inside pressure sensor is located on valve cock pedestal, positioned inside tires, is contacted with gas in tire.
Outside pressure sensor and inside pressure sensor, sensor wireless transport module is passed through by signal by pressure data
The tire pressure monitoring system of automobile is reached in real time.When outside tire pressure is below or above normal atmosphere, itself and standard are calculated respectively
The difference of atmospheric pressure, then tire pressure monitoring system reduce safety tyre pressure value or increase safety tyre pressure value respectively, make tire by outer
Boundary's air pressure changes and is subject to erroneous judgement to affect, it is to avoid suppress tire or traveling of blowing out.
This utility model beneficial effect is
This utility model simple structure, is capable of the interior outside pressure of real-time monitoring tire, and ensures safety tyre pressure value with this
Correct display, make tire over-pressed or under-voltage, it is ensured that traffic safety.
Description of the drawings
This utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation.
Specific embodiment
As shown in figure 1, this utility model is made up of valve cock 1, outside pressure sensor 2 and inside pressure sensor 3.
The valve cock is mainly made up of valve cock pedestal 11, dust cap 12 and valve inside 13.
Outside pressure sensor 2 is fixed on the top of dust cap 12, contacts with external environment, can in real time measure extraneous big
Air pressure.Inside pressure sensor is fixed on valve cock pedestal 11, and positioned inside tires, can in real time measure pressure in tire.
Two pressure transducers form a whole with valve cock, and respectively pressure data can be reached into tire pressure monitoring system
System.When ambient air pressure is less than normal atmosphere, need to correct safety tyre pressure value, PRepair=PMark-PRing；What is now calculated is real-time
Safety tyre pressure value is PAmpere-hour=PAn Biao-PRepair；
Wherein PMarkFor normal atmosphere, PRingFor now ambient atmosphere pressure, PAmpere-hourFor actual time safety tire pressure,PAn BiaoFor standard security
Tire pressure.
When ambient air pressure is higher than normal atmosphere, it is also desirable to correct safety tyre pressure value, PRepair= PRing- PMark；Now
The actual time safety tire pressure value of calculating is PAmpere-hour=PAn Biao+PRepair。
The tire pressure value that only instrument shows is more than or less than PAmpere-hourShi Caihui sends tire pressure warning.When instrument numerical value is more than PAmpere-hour
It is excessive for pressure in tire, gas can be put in tire to correct the problem；When instrument numerical value is less than PAmpere-hour, represent under-voltage in tire, need
Inflate to correct the problem, in this way, so as to realize the safety traffic of automobile.
Those skilled in the art can carry out various remodeling and change to this utility model.Therefore, this utility model covers
The various remodeling covered in the range of falling into appending claims and its equivalent and change.
