The utility model is characterized in that the sensor applies the corrugated pipe, the beeper or the radio transmission technology, has compacted structure, is easy to be processed and assembled, and is more reliable in particular to the sealing and alarming performances.
Description
Affiliated technical field
Title of the present utility model is a tire pressure alarm.Be applied on the automobile, belong to warning device.It is made of sensor and warning box two parts.Sensor directly is positioned on the tire valve, and the warning box is placed in the operator's compartment.When gas in the tire made air pressure reduction or high temperature, overload that air pressure is raise because of leakage, sensor was sent out the dirt induction and is transformed into signal specific according to predetermined force value and is transmitted to the warning box.The warning box sends sound and light alarm.The driver gets off and can find the problem tire immediately.So just can avoid grinding tire or blowing out.
Background technology
Can see the patented technology of relevant tire pressure warning aspect by patent retrieval.In their technical characterictic, the sealing property that has is reliable inadequately, and the needs that have lose heart and report to the police, and installing and using extremely of having bothers, and the manufacturability that has is good inadequately.
Summary of the invention
This tire pressure annunciator will solve four technical matterss: 1, reliable sealing performance; 2, failure-free is reported to the police under the particular pressure value; Performance was unaffected when 3, hot-cool environment used down; 4, the good manufacturability of Sheng Chaning.
This tire pressure alarm designs is made up of sensor and warning box two parts.
Described sensor is made up of 15 kinds of parts, and its planform is seen Figure of description 1: lower casing 1, seal ring 2, push pipe 3, bellows 4, lower contact 5, insolator disc 6, insulation tube 7, anti-loose ring 8, button cell 9, upper contact 10, spring frame 11, spring 12, buzzer phone or transmitting set 13, regulating plate 14, upper casing 15.The shape of these 15 kinds of parts, material, principle and structural relation are as follows:
(1) lower casing 1: material is a copper, and its front end negative thread connects tire tube valve, and the tail end negative thread connects upper casing 15, and inside is cavity, is carrying seal ring 2 successively, and push pipe 3 is welding bellows 4, and insolator disc 6 is arranged on the bellows, tail end precession lower contact 5.
(2) seal ring 2: material silica gel, cross section are circular, and it embeds in the groove of lower casing 1, seals the gas between tire tube valve and the lower casing 1, seals.
(3) push pipe 3: material is a copper, when sensor is screwed on the tire tube valve, by the envelope air valve in its unseat the valve mouth, makes the gas in the tire enter sensor.
(4) bellows 4: material is a copper, is welded on the lower casing 1, plays sealing and conductive gas pressure, and its displacement changes with the tire internal gas pressure, and its sealing property is failure-free, and it is this sensor most important function part.
(5) lower contact 5: material is a copper, its outside thread make it can precession lower casing 1 in, its adjustable positions, it plays double action; The one, the contact of reporting to the police during as tyre underpressure allows the sensor circuit conducting and reports to the police, and the 2nd, as the positioning plate of bellows 4.
(6) insolator disc 6: material is an insulating material, and its effect is to make bellows 4 and button cell 9 insulation.
(7) insulation tube 7: material is an insulating material, and its effect is to allow button cell 9 and lower casing 1 insulation.
(8) anti-loose ring 8: material is a carbon spring steel wires, and its shape is a half-turn, and the two ends bending utilizes its elasticity to inject in the upper casing and lower casing after connecting, makes it and can not become flexible.
(9) button cell 9: it is the electrical source of power of this sensor, and both having joined with upper contact 10 or lower contact 5 as moving contact simultaneously makes circuit turn-on, again as the adjusting and the conveying element of spring pressure value.
(10) upper contact 10: material is a copper, but outside thread precession upper casing 15 is arranged on it, and transfer along with alarming value its position, and it is fixing to mix up the back.When tire pressure rose to alarming value, button cell 9 made the sensor circuit conducting and reports to the police with joining as moving contact.
(11) spring frame 11: material is an insulating material, and it limits the position of spring and makes it and upper contact 10 insulation.
(12) spring 12: material is a carbon spring steel wires, and two ends polish, and its elastic force and tire pressure balance each other, two certain location, there is specific elastic force value position when both upper contact 10 and lower contact 5 are respectively with button cell 9 conductings, and it is one of critical function element of this sensor.
(13) buzzer phone or transmitting set 13: its negative pole links to each other with spring 12 and button cell 9 negative poles, positive terminal place and regulating plate 14 plug, it moves with regulating plate 14 as the base of spring 12 on the one hand, in addition the aspect is sent signal specific and is passed to the warning box when upper contact 10 or lower contact 5 place circuit turn-ons.It is one of critical function element of this sensor.
(14) regulating plate 14: material is a copper, but its outside thread makes it precession upper casing 15, the elastic force value of its mobile adjustable springs, mix up the back sealing fix, it be structural constituent be again the electrical connector element of buzzer phone or transmitting set 13.
(15) upper casing 15: material is a copper, and its front end outside thread and lower casing 1 join, but its negative thread precession upper contact 10 and regulating plate 14 are put into button cell 9 successively in its cavity, insulation tube 7, upper contact 10, spring frame 11, spring 12, buzzer phone or transmitting set 13, regulating plate 14.
Above-mentioned these 15 kinds of parts have constituted the sensor of this tire pressure annunciator jointly.In response to having used the bellows technology, buzzer phone technology or radio transmission technology make its sealing property better, the warning more reliable performance, and be easy to processing, assembling and debugging.Good performance has obtained proof through trial-manufacture of sample.
Described warning box is partly formed by two; See Figure of description 2, by receiving body 1, circuit card assembling 2 is formed, and it converts the signal of sensor emission to electric signal through receiving body 1, the selective frequency amplifier circuit in circuit card assembling 2, and shaping circuit and delay trigger circuit constitute acoustooptic alarm system jointly.
