Description
Technical field
The present invention relates to the system for monitoring pressure in tyre of automobile, relate in particular to a kind of external information transmitter for tire pressure.
Background technology
Air pressure is the parameter of the most critical of tire, and tire pressure is too high or spend the low life-span that all can increase every kilometer fuel consumption and reduce tire.Figure 1A and Figure 1B have embodied respectively the relation between air pressure and tyre life, the oil consumption.Tire pressure is lower than 25% of normal value, and tyre life is reduced to 60%, and oil consumption increases by 3%.In addition, the size of tire pressure directly affects the safety of running car.So tire is installed electronic security(ELSEC) sensing product, and it is very necessary to be used for the Real-Time Monitoring tire pressure.
Tire mainly contains two kinds at present, and a kind of is tubed tyre, and a kind of is tubeless tyre (vacuum tyre).For the development of truck, the utilization of tubeless tyre is trend.But at present still in the truck that uses, there is the truck of the inner tube of a tyre to compare tubeless truck and occupies larger ratio.The truck that the inner tube of a tyre arranged needs the tire pressure of each tire equally for the safety of transporting and the maximization of interests.
The information transmitter for tire pressure of traditional system for monitoring pressure in tyre (TPMS) is built-in, namely be installed in the tire, but the tire dismantling of truck is inconvenient, causes very large difficulty for rear installation of production.And this built-in tire pressure transmitter can not use at the truck that the inner tube of a tyre is arranged.
For this reason, prior art has proposed the tire pressure transmitter of external.
As shown in Figure 2, Chinese patent ZL200520063014.4 has announced a kind of existing external transmitter, and the shell 11 of this transmitter 10 is a cap structure, and has a hickey 12, is screwed on the valve cock 20 transmitter fixing by the mode that screws togather.
This external transmitter mainly contains the shortcoming of two aspects:
1, because whole transmitter all is screwed on the valve cock, the weight of transmitter is all born by valve cock, yet automobile is the tire High Rotation Speed when running at high speed, and when car speed at 100Km/h the time, the centrifugal acceleration that transmitter is subject to is approximately about 200g (acceleration of gravity).Valve cock can be out of shape because being subject to very large power, can cause like this security of whole tire greatly to reduce.
2, this external transmitter is easy to take off, and is therefore stolen easily.Owing to expensive chip is arranged, so the cost of transmitter all is higher in the transmitter.High stolen risk causes this product to be difficult to promote.
Summary of the invention
Technical matters to be solved by this invention provides a kind of external information transmitter for tire pressure, has fixation, non-damageable characteristics.
The present invention is that to solve the problems of the technologies described above the technical scheme that adopts be to propose a kind of external information transmitter for tire pressure, comprises a transmitter electronic module, a holder, a valve connector and a tracheae.Transmitter electronic module is in order to detect and transmitting tire pressure, and this transmitter module has a gas access.Holder has an installation portion and two set collars, and this installation portion is in order to installing this transmitter electronic module, and this two set collar is suitable for being fixed on two adjacent screw on the wheel rim of tire.Valve connector is in order to be combined with the valve cock of tire.Tracheae connects this valve connector and this transmitter electronic module, introduces gas with the gas access from this valve connector to this transmitter electronic module.Wherein between this valve connector and this tracheae, and can relatively rotate between this transmitter electronic module and this tracheae.
In one embodiment of this invention, between this valve connector and this tracheae, and can counterrotating angle be 360 degree between this transmitter electronic module and this tracheae.
In one embodiment of this invention, the material of this tracheae is teflon.
In one embodiment of this invention, this tracheae is by being connected the gas access of this transmitter electronic module with one first high pressure connection, and wherein this tracheae and this first high pressure connection are by the riveted joint of one first riveting sleeve.
In one embodiment of this invention, this tracheae is by being connected this valve connector with one second high pressure connection, and wherein this tracheae and this second high pressure connection are by the riveted joint of one second riveting sleeve.
In one embodiment of this invention, the installation position of this holder is between two set collars.
In one embodiment of this invention, above-mentioned external tire pressure transmitter also comprises a protective cover, is arranged on the installation portion of this holder to hide this transmitter electronic module, and wherein the antenna of this transmitter electronic module is exposed to outside this protective cover.
In one embodiment of this invention, the antenna of this transmitter electronic module stretches out along this tracheae, to pass above-mentioned protective cover.
External information transmitter for tire pressure of the present invention makes it compared with prior art owing to adopt above technical scheme, has following remarkable advantage:
1, adopt the nut on the truck rim to be fixed on the wheel rim, because the nut on the wheel rim all is to adopt the wind big gun of specialty to be installed on the wheel rim, pretightning force is very large, and fixation can't cause damage to valve cock; After installing, do not have professional equipment to be difficult to disassemble, played antitheft function;
2, valve connector and launcher shell can rotate freely, and can adapt to various wheel rim like this, are installed on the different wheel rims, have increased the versatility of transmitter, and are convenient to install.
