Abstract
The invention discloses a built-in type tire pressure monitoring alarm. A shell is internally provided with a reference chamber and an entrance pipe extending from the reference chamber to the direction of a valve rod; the entrance pipe is internally provided with a reference chamber valve which can seal and open the entrance pipe; a valve core of the reference chamber valve is directly abutted against a core rod of an air gate core; in an inflating process, the air gate coreis ejected and the core rod of the air gate core presses the valve core; the reference chamber valve is opened and the reference chamber is inflated; after the inflation process is finished, the air gate core is rebounded; and then the reference chamber valve is closed to seal the reference chamber. When pressure in a tire is too low, an elastic metallic membrane on a wall surface of the reference chamber generates outward deformation due to differential pressure so as to be contacted with an anode contact point of an alarming signal emitting module, so that the alarming signal emitting module is electrified to send out a signal and an alarming device on an automobile receives the signal to alarm. The alarm adopts mechanical sensing so that the work is stable and reliable, the built-in type tire pressure monitoring alarm is applicable to bad working conditions, the fault rate is low and the cost is relatively low.
Description
Technical field
The present invention relates to the device that tire pressure is monitored and reported to the police when tire pressure is too low; A kind of device that tire pressure is monitored and reported to the police that is placed in inside tires particularly.
Background technology
At present, tire pressure monitoring alarm device on the market, be mainly electronic sensor form, by electronic chip, respond to the air pressure in tire, electronic chip needs whole day twenty four hours to be power supply state always, and its consumption of current is large, and battery is easily finished, need often to change, to user, make troubles.Once particularly battery consumption is complete, and user fails to change in time, will cause the warning device cannot 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.
Summary of the invention
The present invention be intended to provide a kind of little power consumption, safe and reliable, can better adapt to harsh environment, and also lower built-in wheel tire pressure monitoring alarm of cost.
Built-in wheel tire pressure monitoring alarm of the present invention, comprise housing and the valve rod communicating with housing, the end of valve rod is provided with valve inside, it is characterized in that: in housing, have reference cavity, alerting signal transmitter module and battery, the part wall of reference cavity is elastic metallic diaphragm, the negative pole contact point of alerting signal transmitter module is connected with the negative electricity of power supply, its anodal contact point near and over against the elastic metallic diaphragm of reference cavity, the elastic metallic diaphragm of reference cavity is electrically connected to the positive pole of battery; Reference cavity is extended with inlet pipe to valve rod direction, is provided with salable and opens the reference cavity valve of inlet pipe in inlet pipe; The inwall of inlet pipe arranges inside boss, the valve body of reference cavity valve is threaded onto in inlet pipe by screw thread, and seal ring sealing is set between boss, the spool of reference cavity valve inserts in valve body middle part and stretches out from valve body front end, on the end of external part, be rotary with nut, the marginal ridge position of nut arranges outward extending annular groove, seal ring is installed in annular groove, spool opposite position is provided with flange, seal ring is clamped between nut and flange, the end face of seal ring exceeds the edge of flange, and it is relative with the front end face of valve body that it exceeds part; The spool core bar direct and valve inside of reference cavity valve offsets, or the core bar by push rod and valve inside offsets, between spool and valve body, spring is installed, spring is to the spool application of force, and the edge that makes seal ring exceed flange can be pressed on the front end face of valve body.
Built-in wheel tire pressure monitoring alarm of the present invention, be installed in tire wheel hub valve port, when to tyre inflating, valve inside in its valve rod is pushed up pressure, the core bar of valve inside or can to promote the core bar of reference cavity valve inner mobile to reference cavity with push rod that core bar offsets, make the seal ring clamping between the annular groove of nut and spool flange follow movement, thereby make the end face of seal ring exceed the marginal portion of flange and the front end face of valve body departs from.Now in opened condition, gas enters in reference cavity from the perforate of reference cavity reference cavity valve.After inflation, valve inside is released, the core bar resilience of valve inside, core bar or push rod be the spool application of force to reference cavity valve no longer, spring is to the spool application of force, and the edge that makes seal ring exceed flange is pressed on the front end face of valve body, makes reference cavity valve be closed condition, reference cavity sealing, keeps the state of constant pressure when charging gas.After pressure drop in tire, because the pressure in reference cavity is constant, therefore the pressure of the inside and outside both sides of reference cavity can exist deviation, now as the elastic metal coating sector-meeting with reference to chamber wall, because of pressure reduction, produce distortion laterally; When tire pressure drops to a certain degree, being deformed to while contacting with the anodal contact point of alerting signal transmitter module of elastic metallic diaphragm, alerting signal transmitter module obtains the electric signal that sends, and the warning device on automobile receives signal, thereby reports to the police.
Described built-in wheel tire pressure monitoring alarm, by the elastic metallic diaphragm as with reference to chamber wall, because of pressure reduction distortion conducting alarm circuit plate, realize monitoring and the warning of tire pressure reduction, it is mechanical type sensing, and working stability is reliable, can be suitable for severe working environment, failure rate is low.And warning device is in the not conducting of non-alarm condition alarm circuit, there is not electric current, do not need to consume the energy, consumption of current is extremely low, do not need frequently to change battery, can not have the problem that causes warning circuit to work because of running down of battery, the potential safety hazard of avoiding so bringing, works safer, reliable.In addition, its cost of elastic metallic diaphragm is far below electronic sensor, and therefore, the cost of built-in wheel tire pressure monitoring alarm of the present invention is also lower.
