When the tire pressure is normal, the convex outer edge of the spring base is positioned above the elastic contact piece and separated from the elastic contact piece; and when the tire pressure is too low, the convex outer edge of the spring base is just overlapped on the elastic contact piece and conducted with the elastic contact piece to enable the anode of a battery to be ultimately conducted with an anode access point of a flasher circuit board through a battery pad, a spring, the spring base, the elastic contact piece and a shell in sequence, and an alarm circuit board obtains an electric alarm. The alarm is only provided with a cavity communicated with the tire pressure, a reference cavity is replaced by the spring, and the alarm does not have requirements for the sealing performance of the upper part of the elastic diaphragm, and is very easy to satisfy the requirements for the sealing performance in use, and reliable and safe to use.
Description
Technical field
The present invention relates to be used for monitoring in real time the device of automotive tire pressure.
Background technology
Motor tire all has a standard pressure usually, and when the pressure of tire was on the low side, the operating characteristic of automobile can be influenced, and Tyte Wear can be aggravated, but also can increase the energy consumption of automobile.Especially, more can bring harmful effect to the driving performance and the safety of automobile when because of the tire pressure of each tire of automobile when unbalanced.
Take place for fear of above-mentioned situation, tire pressure warning device fortune Ying Ersheng, existing then tire pressure warning device is mainly the electronic sensor form; Through the air pressure in the electronic chip induction tire; Electronic chip needs the whole day twenty four hours to be power supply state always, and its consumption of current is big, and battery uses up easily; Need often to change, make troubles to the user.In case particularly battery consumption is intact, and the user fails in time to change, and will cause the warning device can't Normal Alarm, has potential safety hazard.In addition, electronic chip also has requirement to working environment, when meeting rugged environment, and its easy et out of order, cisco unity malfunction.In addition, the electronic chip cost of induction air pressure is also higher.
The tire pressure monitoring warning device that mechanical structure is also arranged; As the patent No. be 201010191711.3, publication number is the disclosed a kind of tire pressure detection alarm device of Chinese patent of 101830152A; It drives the elastic memberance action through reference cavity that is provided with in the warning device and the difference of pressure of monitoring the chamber; Realize the conducting of warning circuit, thereby report to the police that its reliable operation, cost are low.Yet it not only need be provided with the reference cavity that is filled with standard pressure in warning device, and the monitoring chamber that is communicated with tyre cavity with the tire pressure realtime uniform also need be set, and this causes its sealing property to warning device to require high.And the warning device parts are many, and the material of each parts is not quite similar again, its sealing property be difficult to guarantee, the gas leakage that warning device has caused tire on the contrary has been installed sometimes, very inconvenience, and have potential safety hazard.
Summary of the invention
The present invention is intended to provide a kind of sealing property and requires to guarantee that easily cost is lower, and the better monitoring tire pressure annunciator of safety.
Monitoring tire pressure annunciator of the present invention comprises the bottom nut that can be threaded onto on the tyre valve core and is threaded onto the housing on the bottom nut;
Warning circuit plate and battery are installed in the housing; Battery is positioned at the below of warning circuit plate; The negative pole access point of warning circuit plate is connected with the negative electricity of battery, the anodal access point of warning circuit plate and housing conducting, and the periphery of battery separates with housing through non-conductive battery cover;
It is characterized in that: the below of battery is provided with the battery pad and is connected with the positive electrical of battery, and the below of battery pad is provided with insulating mat, and the middle part of insulating mat is provided with through hole, mounting spring and the conducting of battery pad in through hole, spring lower end mounting spring base and spring conducting;
The below of insulating mat is provided with elastic contact chip; Elastic contact chip and housing conducting; The elastic contact chip below is provided with the contact briquetting, and the bottom nut of the below of contact briquetting has the valve plate of inside extension, is formed centrally valve opening in the valve plate; Compress flexible diaphragm between contact briquetting and the valve plate, both sides sealing about the housing is separated;
The spring pedestal of elastic memberance and its top offsets; The elastic memberance below is communicated with the cavity of valve opening below, and the valve opening place is equipped with thimble, and the valve plate bottom is provided with seal ring; When bottom nut is tightened on the valve inside; Thimble can the unseat the valve core, and seal ring go into sealing between valve inside upper end and valve plate, and the elastic memberance below is formed and the corresponding to seal chamber of tire pressure;
Elastic contact chip stretches out to the spring pedestal direction, forms with respect to the insulating mat and the salient that contacts briquetting of both sides up and down, and spring pedestal is provided with the outer rim of protrusion; Tire pressure just often, the outer rim of spring pedestal protrusion is in the top of elastic contact chip; Throw off with elastic contact chip, cross when low at tire pressure, the outer rim of spring pedestal protrusion rides on the elastic contact chip just; With the elastic contact chip conducting; Anode is successively through battery pad, spring, spring pedestal, elastic contact chip, housing, the anodal access point conducting of final and flash circuit board, and the warning circuit plate gets electric alarm.
Monitoring tire pressure annunciator of the present invention during use, is threaded onto bottom nut on the valve inside; In the screw-in process, thimble unseat the valve core, the seal ring of valve inside top and valve plate bottom offsets; Make the diaphragm below form the cavity identical with tire, its pressure is consistent with tire pressure.When tire pressure just often; Pressure in the cavity acts on the elastic memberance, and elastic memberance is popped up, and the outer rim of spring pedestal protrusion is positioned at the top of elastic contact chip; Spring pedestal and not conducting of elastic contact chip; The positive pole and the not conducting of housing of battery also are the anodal access point and the not conducting of anode of warning circuit plate at this moment, and the warning circuit plate is not worked.When tyre inner pressure is crossed when low; Spring promotes spring pedestal and moves down, make the outer rim of spring pedestal protrusion put with elastic contact chip on, with the elastic contact chip conducting; Thereby the positive pole that makes battery passes through battery pad, spring, spring pedestal in the elastic contact chip conducting; Pass through elastic contact chip and housing conducting again, thereby make the anodal conducting of the anodal contact point and the battery of warning circuit plate, the warning circuit plate gets electric alarm.
Said monitoring tire pressure annunciator is reported to the police through upspringing of elastic memberance and return control warning device, and it need not use electronic sensor, simple in structure, reliable operation, and cost is low.And warning device only is provided with a cavity that is communicated with tire pressure in it; Do not need to be provided with simultaneously reference cavity and monitoring chamber; To be action of the spring pass to the power of elastic memberance in spring pedestal to reference pressure again, replaced reference cavity through spring, and it does not have the requirement of sealing property to the elastic memberance upper section; The sealing property that only need guarantee the elastic memberance below gets final product; Sealing property to monitoring device itself is less demanding, thereby it is easy to sealing property requirement that satisfy to use, uses reliable more, safety.
