Description
Technical field
The utility model relates to a kind of warning device of automobile, and is special relevant with a kind of tire alarm device.
Background technology
Automobile under steam, the air pressure of tire can change to some extent.Generally, tire pressure changes does not among a small circle influence driving safety.But air pressure is in that to be subjected to the external interference amplitude of fluctuation big, perhaps internal damage and when not discovered, cause very serious potential safety hazard, even can cause miserable traffic accident.
Given this, the inventor develops a kind of tire alarm device, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of tire alarm device, is used to monitor the situation of tire internal gas pressure, produces alarm when air pressure is too small or excessive.
In order to achieve the above object, solution of the present utility model is:
Tire alarm device comprises air pressure detector, projector, receptor, annunciator and power supply; The air pressure detector is installed in inside tires, has sealed tube, conducting rod, spring, first sheetmetal and second sheetmetal; One end of sealed tube is a film, and the sealing inner axial tube is laid conducting rod, and conducting rod one end is connected on the film, and is vertically installed with electric conductivity excellent contact plate with conducting rod; First sheetmetal is installed on the bottom of sealed tube; Second sheetmetal with through hole is installed in the sealed tube, and conducting rod is set in the through hole and can moves axially, and contact plate can be against on second sheetmetal; Spring is nested with on conducting rod, and spring one end is connected on the contact plate, and the other end is connected on first sheetmetal, and the contact site of the spring and first sheetmetal scribbles insulating material; Power supply one end connects first sheetmetal and second sheetmetal successively, and the other end connects projector and conducting rod successively; The receptor that is used to receive the projector status signal is connected with annunciator.
Each tire all is equipped with air pressure detector and projector, and forms the coding of corresponding tire on the projector, after receptor receives status signal, triggers the alert program of corresponding coding on the annunciator.
After adopting such scheme, automobile in the process of travelling, the air pressure overbalance in tire pressure and the sealed tube, film can be pushed back and forth, thereby the drive conducting rod moves axially.In case the differential pressure of atmospheric pressure in tire pressure and the sealed tube is excessive, conducting rod can touch first sheetmetal or contact plate touches second sheetmetal, thereby connects circuit, make projector work, give receptor emission state signal, after receptor is received status signal, start corresponding alert program.
Like this, unusual when motor tire, the utility model will alarm, can in time stop and check or maintenance that trouble-shooting eliminates safe hidden trouble, and generation avoids traffic accident.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is tire pressure the utility model view when excessive;
Fig. 3 is tire pressure the utility model view when too small.
The specific embodiment
As shown in Figure 1, be structural representation of the present utility model.Tire alarm device comprises air pressure detector 1, projector 2, receptor 3, annunciator 4 and power supply 5.
In the present embodiment, sealed tube 11 is that plastics are made body, an end band back cover, and the other end is by film 16 sealings.
Axially be laid in the conducting rod 12 in the sealed tube 11, pass through hole 17, conducting rod 12 ends are connected with film 16.Conducting rod 12 can adopt electric conductivity good metal material to process.Conducting rod 12 length are slightly less than sealed tube 11 body length, can move axially in sealed tube 11, can be considered sway from Fig. 1.Near through hole 17 places, be vertically installed with contact plate 18 on the conducting rod 12, contact plate 18 also has good electrical conductivity, can adopt identical material with conducting rod.When conducting rod 12 moved right, contact plate 18 was against on second sheetmetal 15.
Under normal condition, spring 13 is not subjected to application force, and conducting rod 12 does not touch first sheetmetal 14 or second sheetmetal 15.
In conjunction with Fig. 1, the circuit of tire alarm device is connected to: an end of power supply 5 at first connects first sheetmetal, 14, the first sheetmetals 14 with lead 61 and is connected with second sheetmetal, 15 usefulness leads 62 again.The other end connection projector 2 of power supply 5 provides operating voltage for projector 2, feasible energising back projector 2 energy normal operation, and projector 2 is connected with conducting rod 12 usefulness leads 63 again.
During use, can air pressure detector 1 and projector 2 all be housed, and form the coding of corresponding tire on the projector 2, after receptor 3 receives status signal, trigger the alert program of corresponding coding on the annunciator 4 each tire of automobile.
The utility model in use, when the tire internal gas pressure just often, the conducting rod 12 in the air pressure detector 1 does not contact not conducting of circuit with first sheetmetal 14 with second sheetmetal 15.Projector 2 does not have operating voltage, does not produce work.
In conjunction with Fig. 2, when the air pressure in the tire was excessive, the air pressure in the air pressure of sealed tube 11 and the tire had pressure reduction, and then film 16 is compressed, and drove conducting rod 12 toward moving left.Pressure reduction surpasses certain limit, the bottom of conducting rod 12 touches first sheetmetal 14, this moment whole circuit by power supply 5 through first sheetmetal 14, conducting rod 12, arrive projector 2 again and form a loop, circuit is connected like this, projector 2 energy normal operation send a status signal for receptor 3, and annunciator 4 produces reports to the police.Behind trouble removal, compressed spring 3 produces restoring force, and conducting rod 12 is sprung back to original position.
In conjunction with Fig. 3, when the air pressure in the tire was too small, film 16 expanded, and drove conducting rod 12 toward moving right.Air pressure surpasses certain limit, the contact plate 18 of conducting rod 12 touches second sheetmetal 15, this moment whole circuit by power supply 5 through first sheetmetal 14, second sheetmetal 15, conducting rod 12, arrive projector 2 again and form a loop, projector 2 energy normal operation, give 3 one status signals of receptor, annunciator 4 produces reports to the police.Behind trouble removal, the spring 3 that is stretched produces restoring force, and conducting rod 12 is returned to original position.
