Abstract
The utility model relates to an automobile tyre leakage detection apparatus, which needs to solve the technical problem that the sound and light alarm signal needs to be emitted to the driver when the air pressure in any vacuum tyre of the automobile is reduced within a certain range. Therefore, a pressure sensor is arranged on the peripheral surface of the external circumference of a hub of a cavity of the vacuum tyre and a rubber sheet is sealed between a casing of the cavity of the vacuum tyre and an upper cover, thus forming a first cavity and a second cavity. The first cavity is a sealing cavity, and a spring and a gasket are arranged in the first cavity; the second cavity is communicated with the cavity of the vacuum tyre. A circuit board of a high-frequency transmitting circuit and a battery are arranged in the second cavity. A transmitting switch is welded on the circuit board and is contacted tightly with the rubber sheet, to emit the signal that the tyre leaks air to the driver when the air pressure of the tyre is low; when the air pressure of the tyre is sufficient, the rubber sheet is separated from the switch and the automobile can be safely driven. The utility model has the beneficial effects of simple and convenient mounting, reliable working and safe driving.
Description
Technical field
The utility model relates to the ride safety of automobile technical field, particularly a kind of tyre leakage detecting device.
Background technology
Automobile is former thereby tire flat takes place because of pricking nail etc. through regular meeting under steam, if do not find early, then can cause damaged tyres or scraps, and even more serious is that traffic accident might take place, and causes the injury of lives and properties.In the ordinary course of things, have only skilled driver to judge whether tire does not have gas, for new chaufeur or road conditions complexity, crankcase ventilaton, just be difficult to find that tire seriously leaks gas according to the phenomenons such as shake of the vibration of automobile, sound, bearing circle, thereby potential safety hazard at any time lies dormant.
Summary of the invention
The technical problems to be solved in the utility model is that the air pressure in the arbitrary vacuum tire of automobile is reduced in the certain limit and will be sent the sound and light alarm signal to chaufeur.
Technical solution of the present utility model is such: a kind of tyre leakage detecting device, comprise high frequency transmission circuit and be contained in high frequency receiving circuit in the operator's compartment and sound, optical alarm circuit, on wheel hub 2 peripheries of vacuum tire 1 inner chamber, pressure sensor 3 is housed, this pressure sensor 3 is provided with shell 10 and loam cake 11, forms first cavity 13 and second cavity 7 by set sheet rubber 5 between shell 10 and loam cake 11; Be provided with spring 12 and pad 4 between sheet rubber 5 in described first cavity 13 and loam cake 11 top inner wall; In described second cavity 7, high frequency transmission circuit wiring board 9 and battery 6 are housed, are contained in emission switch 8 tops and sheet rubber 5 close contact that are in flat state on the wiring board 9.Described first cavity 13 is a sealed cavity.Described second cavity 7 and place vacuum tire 1 intracavity inter-connection.
Above-mentioned each vacuum tire of tyre leakage detecting device is adorned a cover, an automobile is adorned quadruplet altogether, promptly on four vacuum tires in the front, rear, left and right of automobile, respectively adorn a cover, quadruplet high frequency receiving circuit and sound thereof, light crossing-signal are concentrated and are contained in the operator's compartment, make things convenient for the air pressure situation of driver observation and four tires of grasp.
The principle of work of pressure sensor is such: after vacuum tire 1 air pressure surpasses 1 kilogram, air pressure produces an outside application force to sheet rubber 5, make sheet rubber 5 projectioies, make spring 12 compressions by metallic gasket 4, meanwhile, because of leaving emission switch 8, sheet rubber 5 makes it to be in off-state.When air tyre 1 is pricked nail gas leakage, when its tire internal gas pressure is reduced to setting valve, for example, in the time of 1 kilogram, sheet rubber 5 is reset to flat state under spring 12 and metallic gasket 4 effects, at this moment, just, make it be in closure state, high frequency transmission circuit work to emission switch 8 actions, for reducing consumption of current, circuit is cut off the electricity supply automatically after two seconds kinds.After high frequency receiving circuit receives the high-frequency signal of band coding, after decoding and central process unit processing, send the chimes of doom in 10 seconds, and light the indicator lamp of corresponding tire, inform that low tyre of chaufeur, should repair as early as possible or change.
The utlity model has following beneficial effect: because every suit detecting device all is provided with separately independently coding, guarantee can not interfere with each other, can know the tire of gas leakage decompression quickly and accurately; Simple installation, reliable operation are for safe driving provides necessary assurance.
Description of drawings
Fig. 1 is the mounting structure scheme drawing of the utility model pressure sensor.
Fig. 2 is the structural representation of pressure sensor shown in Figure 1, and at this moment, sheet rubber is in flat state, and emission switch is in " closure " state.
Fig. 3 is the structural representation of pressure sensor shown in Figure 1 when being operated in air pressure greater than 1 kilogram of state, and at this moment, sheet rubber is to outer lug and leave emission switch and make it be in " disconnection " state.
The specific embodiment
By following embodiment the utility model is further elaborated in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, shown in Figure 3, a kind of tyre leakage detecting device of embodiment of the utility model is made up of pressure sensor 3, high frequency transmission circuit wiring board 9, battery 6 and high frequency receiving circuit and sound light alarming circuit thereof.This pressure sensor 3 is contained on wheel hub 2 peripheries of vacuum tire 1 inner chamber, and it is made up of shell 10, loam cake 11, sheet rubber 5, spring 12, metallic gasket 4.Loam cake 11 sticks on the shell 10, and loam cake 11 bottoms are pasted with sheet rubber 5, forms first cavity 13, and this is a closed cavity.In this cavity 13, between the sheet rubber 5 at middle part and loam cake 11 top inner wall spring 12 and metallic gasket 4 are housed.Form second cavity 7 between shell 10 and the sheet rubber 5, this cavity 7 connects with vacuum tire 1 inner chamber.High frequency transmission circuit wiring board 9 and battery 6 are housed in second cavity 7, and the center of corresponding sheet rubber 5 is welded with an emission switch 8 on wiring board 9, control high frequency transmission circuit energising work or closed condition.One wheel threatened abortion gas detecting device all respectively is housed on the vacuum tyre of automobile front, rear, left and right, during the motor tire normal condition, these sheet rubber 5 evaginations, emission switch 8 contact opens.During tyre leakage, in the vacuum tyre internal gas pressure drops to 1-1.5 kilogram scope, then this sheet rubber 5 recovers original flat state, push down emission switch 8 and make its closing of contact, high frequency transmission circuit energising work, send the band coded high-frequency signals, be contained in after high frequency receiving circuit in the operator's compartment receives signal, carry out signal conditioning through decoding input micro controller system, bright by buzzer warning and indicator lamp then, inform that tire flat of chaufeur, and reached hazard level, must repair as early as possible or change.
