Description
Technical field
The present invention relates to a kind of device that can monitor automotive tire pressure in real time.
Background technology
Motor tire 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 when on the low side because of a pressure in the motor tire, when causing four tire pressures unbalanced, not only there are the problems referred to above, also can prolong the braking distance of automobile, even the possibility of sideslip and upset is arranged, the safety of automobile is brought influence.
Generation for fear of above-mentioned situation, the patent No. provides a kind of tire pressure monitoring alarm device for the patent of " ZL201210191711.3 ", when it uses, bottom nut is threaded onto on the valve inside, in the screw-in process, the valve inside spring presses off the valve inside mouth, and the pressure in the tire enters into monitoring cavity with reference to cavity and reference cavity top respectively by two passes, at this moment, with reference to cavity, the monitoring cavity all consistent with the pressure of inside tires.Continue to screw in, when bottom nut was rotated in place, the valve inside top was pressed on the reference cavity porthole with the seal ring in the annular groove and goes out, with its sealing; At this moment, reference cavity is isolated, and remains the initial pressure of tire; And the gas passage of reference cavity top monitoring cavity still is communicated with, and keeps consistent with tire pressure, reduces with the reduction of tire pressure.When tire pressure is lower than the initial pressure certain value, poor effect is stressed, upwards distortion of elastic conduction sector-meeting with reference to the cavity top, promotion is fitted in the together upwards distortion of elastic conducting strip at its top, make the negative pole conducting of elastic conducting strip and battery, thereby make the warning circuit plate get electric alarm, thereby, realize the monitoring to tire pressure.
But existing tire pressure monitoring alarm device when mounted, can't its each parts of self check whether can normal operation, whether can't verify has reference pressure to enter reference cavity, so, after tire pressure monitoring alarm device that can't normal operation was mounted, it not only can not be monitored tire pressure, and can be because people's anaclisis, even tire pressure is on the low side, the user can think that still pressure is normal; In addition, existing tire pressure monitoring alarm device, when the eyeglass at its top broke, the pressure in the tire pressure monitoring alarm device can be revealed away from broken position, causes, and tire pressure monitoring alarm device can't normal operation.
Summary of the invention
The object of the present invention is to provide when mounted a kind of, can self check its can normal operation tire pressure monitoring alarm device.
Tire pressure monitoring alarm device of the present invention, comprise the bottom nut that can be threaded onto on the tyre valve core and the housing that is threaded onto on the bottom nut, the bottom of housing and bottom nut sealing, case top has lens, lens are with case top and extraneous sealing, the inner space that housing and bottom nut constitute is equipped with warning circuit plate, battery, elastic conducting strip, reference cavity assembly and top spring from top to bottom; The anodal leading-in end of warning circuit plate directly or by electric-conductor and the anode conducting below it, the negative pole of warning circuit plate is electrically connected with elastic conducting strip; Fitting in elastic conducting strip and reference cavity assembly top, forms with reference to cavity with the space at reference cavity assembly top; When the elastic conducting strip pressurized is heaved, can with the negative pole conducting of battery, the bottom of reference cavity assembly has the free air diffuser that is communicated with the reference cavity, the valve sealing circle of the outlet section setting of bottom nut and valve inside oral area sealing; Valve inside pushes up between the bottom of reference cavity assembly and valve sealing circle, the step of its bottom is inserted in the inside of valve sealing circle, the position of corresponding free air diffuser below arranges the primary seal circle between top and the reference cavity assembly, this primary seal circle completely cuts off the inboard on the valve inside top path to free air diffuser with outer side seal, leave the gap that moves up and down for the valve inside top between reference cavity assembly bottom and the valve sealing circle, bottom nut screws in the process of valve inside, the valve sealing circle can promote the upwards jacking of valve inside top, finally make the primary seal circle be pressed on reference cavity assembly bottom, gas passage is sealed; Between the bottom of valve inside top and reference cavity assembly stage clip is installed, when bottom nut screwed out, stage clip can promote the valve inside top and the valve sealing circle moves down; The outside wall surface of valve plunger tip will be positioned at the space sealing of elastic conducting strip top for independently monitoring cavity by being contained in self check seal ring and the bottom nut sealing on the bottom nut; Also be provided with the side gas passage on the wall on described valve inside top, the side gas passage is positioned at the position near the self check seal ring, in valve inside pushed up by the jacking process, the side gas passage moved to the top of self check seal ring gradually from self check seal ring below, be connected with the monitoring cavity.
Tire pressure monitoring alarm device of the present invention, during use, bottom nut is threaded onto on the valve inside, in the screw-in process, valve inside withstands under the effect of spring and presses off the valve inside mouth, pressure in the tire enters into reference to cavity by gas passage, and the side gas passage is owing to compressed sealing by the self check seal ring, gas can't enter the monitoring cavity from the side gas passage, at this moment, elastic conducting strip is under the difference of pressure effect between reference cavity and the monitoring cavity, upwards heave, with the negative pole conducting of battery, make the warning circuit plate get electric alarm, the expression tire pressure monitoring alarm device can normal operation (as the warning circuit plate electric alarm, illustrate that then tire pressure monitoring alarm device can't normal operation); Continue to screw in, the side gas passage is communicated with the monitoring cavity gradually along with going up of valve inside top is mobile, tire pressure enters the monitoring cavity from the side gas passage, until the pressure of monitoring in the cavity with reference to the equilibrium of pressure in the cavity, this moment, the elastic conducting strip resilience restPosed, the negative pole of battery is disconnected, and the outage of warning circuit plate stops to report to the police; Continue to screw in when putting in place to bottom nut, the valve inside top is pressed on gas passage mouth place with the primary seal circle, with its sealing, at this moment, is isolated with reference to cavity, remains the initial pressure of tire again; And the gas passage of monitoring cavity still is communicated with, and keeps consistent with tire pressure, reduces with the reduction of tire pressure.When tire pressure was lower than the initial pressure certain value, the poor effect that is stressed was upwards heaved with reference to the elastic conduction sector-meeting at cavity top, makes the negative pole conducting of elastic conducting strip and battery, thereby makes the warning circuit plate get electric alarm, realized the monitoring to tire pressure.
Carry out self check when mounted earlier, can guarantee that it is installed on the tyre valve core after, can normal operation, monitor the pressure condition of tire in real time, in time pressure tire on the low side is carried out ftercompction, thereby keeps good operating characteristic and the safety performance of automobile.
