And, send signal from each pressure monitor, promptly the signal that the electric wave of certain frequency (for example, the MHz of hundreds of band RF (RadioFrequency) signal) is changed into carrier wave sends by wireless telecommunications again, receiving device 2 can receive this signal, thereby makes certain indication.
The receiving device 2 that the front is said possesses two parts, promptly in each tire location accordingly can display of tyre display part and produce the expression means of the bright lamp caution or the caution of turning off the light according to the signal that receives.From and air pressure monitoring device 1A that be set out corresponding with each tire location, 1B, 1C, 1D send signal there, according to those signals, and that intention of expression that can be correct.
Then, describe air pressure monitoring device in detail by Fig. 2 to Fig. 4.
The shown air pressure monitoring device 1a of Fig. 2 has disposed following several devices in order: can freely pluck the tire valve that unloads and adorn part 11, Pressure monitoring part 12, control circuit part 13, the battery container part 14 that can freely exchange button cell and the radio part 15 of posting a letter on the thread part of tire valve.In addition, the tire valve said of front is being adorned part 11 and had following components: rounded cylindrical is adorning thread part 11a, base section 11b and part 11c is accommodated in monitoring.Thread part 11a is equipped with the female thread part with the tire valve bolt.Base portion 11b is being mounted the top of thread part, is extended to radial direction.Monitoring is accommodated part 11c and is linked to each other with the top of this base portion 11b, and Pressure monitoring part 12 is equipped with in inside.
In addition, if the thread part 11a that adorning that the front is said is screwed into 31 li of tire valves, protrusion 17 will push valve inside, by via the pressurized air of wheel tyre cavity is imported to 12 li of the Pressure monitoring parts said the front.The pressurized air that the front is said is directed to 12 li of Pressure monitoring parts, but can not invade the control circuit 13 battery container parts 14 that are positioned at its top and the inside of the part 15 of posting a letter.
In addition, accommodate in the monitoring of rounded cylindrical inside the thread part 11e in the part 11c outside, the cover 16 that covers all things in the combiner is fixed with screw.With screw fixedly cover 16 time,,, when keeping good air-tightness and preventing escape of air in the monitoring device, also can prevent the intrusion of outside aqueous vapor so just on rubber ring 18 pads in order to inlay thread part 11e.
Like this, control circuit part 13, the battery container part 14 and the part 15 of posting a letter are placed in the capsule, just can keep good air-tightness.Therefore, electric substrate and battery can be because of aqueous vapor and moisture etc. deterioration gradually, also can not consume certainly, thus can stabilize for a long time tire carried out air pressure monitor.
The control circuit part 13 that the front is said has the setting technical ability that preestablishes atmospheric pressure value and battery voltage value and can do the comparison function that deviates and monitor to tire pressure and cell pressure.When detecting lower than pre-determined tire pressure the time, or lower than pre-determined cell pressure the time, the fwd part of posting a letter will be sent certain signal (RF of 315MHz)
Have substrate 12b and elasticity on the Pressure monitoring part 12 that the front is said and pay the material 12d of portion.Monitoring bolt 12a is housed on the substrate 12b; Metal sheet 12c is equipped with at the top that elasticity is paid the material 12d of portion, metal sheet 12c with monitoring bolt 12a can freely connect from.The elasticity that the front is said is paid the flexible power of the material 12d of portion, can pay gesture metal sheet 12c to the direction of tire valve, if than the front say the fixed big tire pressure of elastic force because tire pressure, the direction that metal sheet 12c will push to monitor bolt 12a to moves.
Therefore, to preestablish the elastic force that elasticity is paid the material 12c of portion and become certain elastic force, if tire pressure is bigger than predetermined force value, the metal sheet 12c that the front is said will be anti-mutually with elastic force, thereby 12a joins with the monitoring bolt, tire pressure is lower than predetermined force value, and metal sheet 12c will deviate from monitoring bolt 12a because of elastic force.
Also have, monitoring bolt 12a and metal sheet 12c begin to deviate from from the state that engages, that moment the form with electric signal be captured.That signal is established bolt 13a and is passed to control circuit part 13 from substrate 12b by upright.The upright bolt 13a that establishes that the front is said also is a channel bolt of passing on electric signal in the pad of doing substrate 12b and control circuit portion 13.After the control circuit part 13 that the front is said receives the signal of the substrate 12b that says the front, just can judge the low situation of tire pressure takes place, the part 15 of posting a letter is passed in that instruction that sends warning signal.
That is to say that the air pressure monitoring device 1a that the front is said is when tire pressure is lower than predetermined force value, the Machinery Ministry product (metal sheet 12c) that are endowed elastic force will move, and 12a deviates from mutually with the monitoring bolt, becomes the mechanical type monitor that transmits.
Therefore, during give a signal will according to fixed atmospheric pressure value (for example 22.5psi or 1.58kg/ sq cm) send.Air pressure monitoring device 1a purchases the elasticity of giving elastic force and pays the material 12c of portion, if purchase this device, when atmospheric pressure value is lower than predefined atmospheric pressure value, just can send certain signal.This air pressure monitoring device 1a can be redefined for the elastic force that the front is said suitable manned vehicle simultaneously, and the elastic force of pickup truck and large truck makes various tire all have super performance.
The battery container part 14 that the front is said in control circuit part 13 with post a letter between the part 15, so just makes button cell BT freely be mounted for possibility.In addition, be installed in the button cell BT of battery container part 14, thereby its above-below direction forms the structure of being supported by elasticity owing to have the support material of conduction property.The control circuit part 13 of descending both sides thereon and the part 15 of posting a letter can be switched on.
If take cover 16, control circuit part of being said in front 13 and the button cell BT that post a letter between the part 15 and to be clamped as three wise quilts allow the direction of taking of cover 16 that it says from the front skid off just and can take off with the side of vertical direction.In dress button cell BT, on the contrary, just be allowed to condition at control circuit part 13 and post a letter and slide into just between the part 15 and can load onto.
Just, in dress button cell BT, in the control circuit part 13 and the additional any external force between the part 15 of posting a letter, can damage monitoring device main body, can safety install.And, because can install, tire valve 31 do not paid yet add any pressure, thereby can install easily from the side.
As shown in Figure 3, the air pressure monitoring device 1a of air pressure monitoring device 1b and fwd explanation is the same, is furnished with tire valve in regular turn and is adorning part 11, Pressure monitoring part 12, control circuit part 13, battery container part 14 and the radio part 15 of posting a letter.In addition, the tire valve said of front is being adorned part 11 also following configuration: rounded cylindrical is being adorned thread part 11a, base portion 11b and part 11c is accommodated in monitoring.Thread part 11a is equipped with the female screw with the tire valve bolt, and base portion 11b is being mounted the top of screw portion, is extended to radial direction, and monitoring is accommodated part 11c and linked to each other with the top of this base portion 11b, and Pressure monitoring part 12 is equipped with in inside.
In addition, accommodate the thread part 11e the inside in the part 11c outside in the monitoring of rounded cylindrical, the cover 16 that covers all things in the combiner is fixed by screw, after adorning thread part 11a and being screwed into tire valve 31, outshot 17 will push valve inside, by conduction path the pressurized air of wheel tyre cavity is imported to 12 li of the Pressure monitoring parts said the front, this structure is also identical.
Just, the Pressure monitoring part 12 that the front is said has possessed the pressure monitor 12A of the conversion electric signal according to tire pressure, when tire pressure is lower than scheduled pressure value, just being sent to control circuit 13 from substrate 12b with the corresponding signal of tire pressure.And, can be emitted in the control circuit 13 predefined signal (the RF signal of 315MHz).
Therefore, the air pressure monitoring device 1b that says of front just can full-time check the tire pressure.When tire pressure is lower than predetermined force value, just become a kind of electronic monitor that can send certain warning signal.
In addition, if the electronic type monitor according to the minimizing situation of tire pressure, also can send caution signal and warning signal stage by stage, the program that sets is put in the control circuit 13, just can sends certain caution signal or warning signal according to the air pressure situation of tire.
In addition, the electronic type monitor can be monitored the tire pressure value at any time, if adopt receiving device, represents technical ability because this receiving device has this that atmospheric pressure value is shown with digital mode, and is very effective for direct understanding tire pressure minimizing situation.Aspect example,, implement to monitor the program of tire pressure, and can in 5 milliseconds time moment, detect each force value with 5.3 seconds time in order to extend the life of a cell.In common tire air pressure monitoring, power consumption is few, only is just to send signal in lower than predetermined force value, and the time of sending signal also only with in 20 milliseconds, has been played the effect of inhibition power consumption.
If picture is at that rate above, can be very clear and definite inform battery life in this form, button cell can be with more than 2 years, the occasion of 5.3 seconds Pressure monitorings is the longest can be with more than 5 years.
As previously mentioned, when detecting tire pressure or cell pressure than predetermined low the time, the portion of posting a letter that the front is said just can send certain signal (the RF signal of 315MHz),
As shown in Figure 4, air pressure monitoring device 1c has following structure: tubular body thing 11A, valve inside 11B and monitoring case 19.Tubular body thing 11A is fixed on 31 li of tire valves with screw, the valve center is embedded on the air control valve 11C, and air control valve 11C is installed in tubular body thing 11A front portion, the sidepiece of the tubular body 11A that monitoring case 19 is said from the front is outstanding, is provided with the air via and can allows air freely come in and go out.The valve inside 11B that the front is said, with when the female screw portion of the inboard of tire valve 31 combines, the male thread part that also has the screw chevron shape that is up drawn as the obtuse angle, it is when being installed into tire valve 31, and the air in the tire is free to enter by air via 11e the monitoring case 19 from the clearance portion there that forms in screw portion.And, in monitoring case 19, installed pressure detector 12B, control circuit 13, battery container 14 and radio that electronic type the detects parts such as portion 15 of posting a letter.
Even the control circuit of being said in front 13 has possessed two kinds of functions, promptly preestablish certain air pressure and cell pressure setting technical ability and can setting value with newly detect tire pressure and cell pressure and do the comparison function of the monitoring that deviates.Therefore, when detecting tire pressure lower than predetermined pressure by air pressure value the time, or detect the predetermined cell pressure of the voltage ratio of button cell BT low the time, the front part 15 of posting a letter will be sent certain signal.
This air pressure monitoring device 1c, 11B forms by valve inside.Dress air control valve 11C in the valve inside 11B.Toward before tire valve 31 in by dress air pressure monitoring device 1c in, the predefined air control valve of taking-up also can be used as air control valve 11C and is utilized, this air control valve 11C is installed on the valve inside.Valve 11C is because have air inlet 11D on top, so can supply with ozone therefrom in air control.Install on the tire valve after the air pressure monitoring device, moving the doing that can put on the air to the air of tire or exit simultaneously need not be dismantled mounted pressure monitoring device.
If the air that the front is said control valve 11C is installed in that valve inside 11B goes up or the valve inside 11B that the front is said is installed on the tire valve 31 (in tubular body 11A is housed), just must use special tool can make it to rotate installation.
Therefore, if must could be installed in air pressure monitoring device 1c on the tire tube valve, so just must re-use special tool valve inside 11B is conformed to the principle of simplicity to take off on shape body part 11A and the tire valve 31 with special tool.Like this, air pressure monitoring device 1c is installed on the tire valve 31 by crash-resistant, forms not allow caducous structure, and therefore, it is very convenient that air pressure monitoring device is installed on the car of long-distance running.And except special tool, other general purpose tool can not take off, and has so just strengthened anti-theft effect.Therefore for the vehicle that stops outside the room, air pressure monitoring device is a kind of good configuration.
18A, 18B, 18C are respectively rubber sheet gaskets, for the air-tightness that increases air pressure monitoring device 1c is used.When tubular body 11A is installed in tire valve 31, air-tightness and impregnability have just been strengthened by cushioning rubber sheet gasket 18A.And, can strengthen air-tightness and the impregnability of tubular body 11A and valve inside 11B by rubber sheet gasket 18B.The air-tightness that keeps valve inside 11B at last by rubber sheet gasket 18C.
This is by monitoring case 19 and be fixed on the chest basal part 19A that the tubular body becomes one with it and can form with the lid part 19B that basal part freely separates.After the cover section that the front is said is taken off, just can freely exchange the button cell BT that in battery container portion, is holding.Even therefore air pressure monitoring device 1c is fixed on the tire valve 31 by crash-resistant, also can carry out battery swap easily.Certainly, chest base part 19A is connected by rubber sheet gasket with lid part 19B, has increased air-tightness and moisture resistance, prevents that also the interior air of tire is from monitoring case 19 past external leakages.
Button cell BT is at control circuit 13 and post a letter between the part 15, when the elasticity support is done with conductive material in its both sides, the control circuit 13 and the part of posting a letter of both sides also can be conducted electricity for 15 li, the air pressure monitoring device 1a that this constitutes and the front is said, and the occasion of 1b is identical.
Above illustrated air pressure monitoring device 1a, 1b, 1c are applicable to different car bodies, if it is just passable that identical monitoring device is installed on whole tires.But generally speaking, on common car, stipulated the tire pressure of standard, if tire pressure compare fixed force value low the time, send warning signal just.
For this reason, concerning common car, it is just passable to install the air pressure monitoring device 1a that belongs to the mechanical type monitor.Also can install the air pressure monitoring device 1a that can set the atmospheric pressure value that sends warning signal (for example 22.5psi or 1.58kg/ sq cm), like this as long as in car, install receiving device.
In addition, for running long-distance truck at those, because think to understand timely situation and clear and definite its interim situation about reducing that tire pressure reduces, therefore installing can display of tyre air pressure, also can send air pressure monitoring device 1a, the 1c of different phase caution signal and warning signal, install the receiving device of can display frame and sounding again, just very perfect.
