Abstract
The utility model provides a tyre pressure limited annunciator capable of inspecting the pressure of the car tyre at any time. The structure of the annunciator is composed of a tyre pressure sensor, a tyre pressure signal emitter and a tyre pressure signal receiver. The tyre pressure sensor is fixed on a bleed valve of the tyre; the tyre pressure signal emitter is fixed in the middle of a hub and the tyre pressure signal receiver is arranged on a dashboard of the cab. Compared with the prior art, the tyre pressure limited annunciator of the utility model is characterized by reasonable design, simple structure, easy process, small volume, convenient use and safety and reliability and can be used on the tyre of various cars, which is a necessity for the modern transportation, therefore has good expansion use value.
Description
1, technical field
The utility model relates to a kind of vehicle body fittings, specifically a kind of tire pressure limiting annunciator that is used for the monitoring wheel tire pressure.
2, technical background
The tire of current mobility car mostly is air-inflation tyre, air pressure in the tire is remained in the range of pressure of regulation, be the service life of improving tire, the key factor that reduces cost of transportation, assurance traffic safety, prior art checks that the method for tire pressure is instrumental method and appearance method, instrumental method is to use the tire pressure measurement instrument, during inspection loadometer is pressed on the valve nozzle of tire, allow the interior gas of tire promote the barograph scale, the number pressure of reading in the tire from scale supplies chaufeur or maintainer's reference.Appearance method is examined wheel tire pressure landearth-circumstance condition with observing exactly, is pressed in the size that ground length is judged tire pressure by tire tread.Some old chaufeur is also kicked tire by pin and is listened its sound to judge the size of inside tires pressure, the in use existing deficiency of said method is to carry out under the static state of tire, detect when being vehicle immobilization, measured pressure value is estimative figure roughly, thereby relatively backward, can not satisfy the needs of modern transportation.
3, summary of the invention
The purpose of this utility model provides the dynamic auto pressure measurement transmission over radio of a kind of tire pressure, can just can carry out the tire pressure limiting annunciator of detection alarm in operator's compartment in parking or vehicle ' process to tire.
The purpose of this utility model realizes in the following manner, on the valve nozzle of each tire of automobile, a sensor of being made up of elastic corrugated diaphragm and contact switch is installed all, on the elastic corrugated diaphragm moving contact is set, elastic corrugated diaphragm is subjected to the control of tire pressure, two fixed contacts of upper pressure limit and lower limit are set on the casing of sensor, when excessive or too small two fixed contacts of moving contact and pressure bound that can both allow of tire pressure contact, the wireless signal transmitter that is arranged on the tire is transmitted to receptor in the operator's compartment with pressure signal, receptor receives that signal just sends over voltage alarm or undervoltage warning, chaufeur is then according to circumstances in time handled tire, such as pressure little can in time inflate timely pressure release that pressure is big or reduce the loaded weight etc. of vehicle cargo.
Accompanying drawing 1 is tire pressure sensor and the mounting structure scheme drawing of tire pressure signal projector on tire;
Accompanying drawing 2 is the tire pressure sensor structural representation of single admission port;
Accompanying drawing 3 is the tire pressure sensor structural representation of three-way pipe for casing.
4, description of drawings
Explain below with reference to Figure of description pressure limitting alarm for tyre of the present utility model being done.
Pressure limitting alarm for tyre of the present utility model, its structure (as shown in Figure 2) is by casing 2, loam cake 1, elastic corrugated diaphragm 10, sealing gasket 9 and contact switch consist of, and the bottom of casing 2 is provided with screw thread The hole is provided with sealing gasket 9 in the screwed hole, the valve nozzle 11 of tire is screwed in the screwed hole tight with sealing gasket 9 Join, the recessed bowl edge on the edge of cancave bowl shaped loam cake 1 and casing 2 tops joins fixing, elastic corrugated diaphragm 10 are clipped between casing 2 and the loam cake 1 loam cake 1 are become two parts, loam cake 1 with space interval between the casing 2 The centre be provided with insulation board 12, be provided with two conductions nuts 8 and air-vents 5 on the insulation board 12, conduction The bolt 7 that can do to adjust up and down is set in the nut 8, and the lower end of bolt 7 is provided with discoid fixed contact 6, circle The edge of plate-like fixed contact 6 joins with the T shape movable contacts 4 that are arranged on centre above the elastic corrugated diaphragm 10, Two conduction nuts 8 join by lead 13 and tire pressure signal projector 14.
(as shown in Figure 2) in order to improve the fatigue resistance of elastic corrugated diaphragm 10, at elastic corrugated diaphragm 10 upper and lower surface is respectively arranged with spring 3.
(as shown in Figure 1) tire pressure signal projector 14 is fixed on the centre of wheel hub 16, and tire pressure signal projector 14 is linked up with the tire pressure alarm receiver 15 on being arranged on the bridge instrumentation dish mutually by wireless signal.
5, embodiment
Its processing and fabricating of tire pressure limiting annunciator of the present utility model is very simple and convenient, and the loam cake of tire pressure sensor and casing can be made with brass shown in the by specification accompanying drawing, and elastic corrugated diaphragm can be made with steel plate or ageing-resistant rubber plate.Pressure signal projector and pressure alarm receptor can be selected commercially available universal miniature short-distance wireless communication equipment product for use.
Install and use also very simple and convenient, tire pressure sensor can directly be screwed on the valve nozzle, tighten the air pressure in the rear tyre and the pressure of elastic corrugated diaphragm lower room and reach balance, elastic corrugated diaphragm can enter mode of operation, T shape moving contact contacted with the disk fixed contact that is in upper limit position when pressure was excessive, pressure hour T shape moving contact contacts with the disk fixed contact that is in the lower position, and pressure bound adjustable bolt can be proofreaied and correct the debugging rear enclosed by master gauge and use.The air pressure signal projector preferably is fixed on the centre of wheel hub to prevent to destroy the original kinetic balance of tire.
Give for convenience inflation of tire, casing also can be designed to the threeway tubulose, and the three-way pipe wherein original tire valve of a termination is chewed, and an end is made new inflation of tire and chewed, can not will during inflation sensor unload.
Pressure limitting alarm for tyre of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to the characteristics such as processing, volume is little, esy to use, safe and reliable, can be at the wheel of various vehicles Using on the tire, is the essential product of modern transportation instrument. Thereby, have the valency of well promoting the use of Value.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
