Specific embodiment

As illustrated in fig. 1 and 2, a kind of automobile tire pressure detector, including sleeve pipe 1, is sequentially provided with from top to bottom in sleeve pipe 1 First dividing plate 2, the dividing plate 4 of second partition 3 and the 3rd；

Piston 5 is installed in sleeve pipe 1 between the first dividing plate 2 and second partition 3, is fixed with the upper surface of piston 5 The electrode needle 7 of the bar of piston 5 and " L " shape, is cased with compression spring 6 outside the bar of piston 5, and the lower end of spring 6 is fixed on the upper end of piston 5 On face, the upper end of spring 6 is resisted against the lower surface of the first dividing plate 2, and the one end of electrode needle 7 contacts with the internal face of sleeve pipe 1；

Multiple air-vents 92 are offered on the end face of second partition 3, at the middle part of the 3rd dividing plate 4 through hole 22 is offered, one Push rod 91 is fixedly connected through through hole 22 with second partition 3, and on end face of the 3rd dividing plate 4 away from second partition 3 rubber is fixed with Glue sealing ring 21, on the inwall of sleeve pipe 1 below the 3rd dividing plate 4 female thread 10 being engaged with cranked tire valve external screw thread is provided with；

Low-field electrode block 52 and high-field electrode block are fixed with the outer wall of sleeve pipe 1 between the first dividing plate 2 and second partition 3 51, high-field electrode block 51 is located at the top of low-field electrode block 52, and electrode needle 7, can be with low-field electrode during moving up and down Block 52 or high-field electrode block 51 contact；

Bulb 8 is installed on the first dividing plate 2, power supply 9 and resistance 53 are fixed with outside sleeve pipe 1, electrode needle 7 is connected to lamp One end of bubble 8, the other end of bulb 8 is connected to the negative pole of power supply 9, and high-field electrode block 51 and low-field electrode block 52 are connected to power supply 9 Positive pole, is in series with resistance 53 on the circuit that low-field electrode block 52 is connected with power supply 9.

After sleeve pipe 1 is tightened onto on automobile tire valve, push rod 91 promotes the movement of valve valve inside, on the 3rd dividing plate 4 Sealing ring 21 be pressed on valve seal, at this moment the gas in tire sequentially passes through through hole 22 and air-vent 92, enter into piston 5 with In cavity between second partition 3, and then shifting on piston 5, the push the spring 6 of piston 5 is promoted to compress, electrode needle 7 is understood and the side of sleeve pipe 1 High-field electrode block 51 and the contact of low-field electrode block 52 on wall（Equivalent to two contacts of switch）Contact.

If tire pressure is too high, piston 5 moves up more, and the electrode needle 7 on piston 5 is moved upwards up to and high-field electrode block 51 contact, circuit turn-on, and bulb 8 is shinny, remind driver to need to reduce tire pressure, it is ensured that vehicle safe driving；When electrode needle 7 to On be moved to low-field electrode block 52, be connected with resistance 53 on the circuit being connected with power supply 9 due to low-field electrode block 52, thus bulb 8 brightness substantially become dull, then illustrate that the vehicle tire pressure is not enough, need to tire pressurization；When vehicle tire pressure is normal, electrode needle 7 is then Between high-field electrode and low-field electrode, for off-state, pressure of tire is normal, i.e., bulb 8 does not work for circuit.

The intensity of the compression spring 6 used in it can be configured according to different vehicles, for example：Ford/Carnival Automotive needs tire pressure 1.8bar, and masses/Passat automotive needs tire pressure is in 2.8bar, at this moment can according to the difference of vehicle come The apolegamy different spring 6 of compressive strength, as long as ensure tire normal tire pressure, electrode needle 7 is located at high-field electrode block 51 and low pressure Both may be used between electrode block 52；Such as Ford/Carnival automobile, when tire pressure is in 1.7bar, electrode needle 7 connects with low-field electrode block 52 Touch, in tire pressure 1.9bar, electrode needle 7 is contacted with high-field electrode block, then tire pressure is normal in 1.7bar to 1.9bar for tire pressure, electrode Pin 7 is between electrode block 51 and low-field electrode block 52.
