Abstract
The invention relates to a vehicle tyre monitoring system and particularly relates to a built-in auto tyre pressure detection system. The built-in auto tyre pressure detection system comprises a wheel hub and an emitter. The emitter comprises a printed wiring board. The printed wiring board is provided with a power supply source, a micro-control unit, a pressure sensor, a temperature sensor and a back end of an emission antenna. The printed wiring board is connected to the wheel hub. The emission antenna is contacted with the wheel hub. The wheel hub is driven as the front end of the emission antenna. Signals are radiated through the wheel hub. The auto tyre pressure detection system is cost-saving, uniform in emission effect and long in service lifetime and is convenient to install and disassemble.
Description
Technical field
The present invention relates to the tire monitor system of vehicle.
Background technology
Along with the expansion of field of application and the increasing gradually of quantity of vehicle, the fast development of express highway network, makes the also corresponding raising of moving velocity of vehicle, so the requirement of reliability to vehicle, safety also improves day by day.In the traffic accident causing because of reasons such as tires, the overwhelming majority is because tire pressure problem causes.Along with traffic volume of highway increases rapidly, overloading is day by day serious, makes highway, bridge, other facility havoc and personal casualty, and traffic accident is occurred again and again.These traffic accident great majority are all because the excessive reason of load carrying ability of the superpressure of vehicle tyre, under-voltage, excess Temperature and vehicle causes.
In order to ensure the optimum drive state of vehicle and economy, reliability, safety and the road-holding property of Vehicle Driving Cycle, many countries make laws in the world, will be in recent years (U.S. enforces) enforce the tire pressure monitoring system (TPMS of vehicular traffic, Tire Pressure Monitoring System), monitoring tire pressure, guarantees traffic safety.
The projector of vehicle tire pressure detection system (TPMS) is mainly divided into built-in projector and external projector at present, and this patent is described mainly for the mounting means of built-in projector and the type of high-frequency emission antenna.The current mounting means of built-in projector is mounted in tire the inside, replace the position of original-pack tire tube valve, normally TPMS maker special design and the manufacture of this quasi-valve mouth, on common tire tube valve basis, one end is with emitting antenna, and the other end is with sensor assembly (this end is inserted inside tires).The built-in projector of this class, its emitting antenna mainly makees antenna as main take coil spring antenna or tire tube valve.
The installation of current built-in projector, is to be mainly fixed on the original-pack tire tube valve of inside tires place, and tire tube valve also must be transformed into the structure that built-in projector can be installed especially, and this special tire tube valve becomes the component part of TPMS, and its shortcoming is:
1, TPMS maker designs, manufactures and this special tire tube valve is provided, and replaces the original tire tube valve of motor tire, causes unnecessary waste.
2, this tire tube valve is not by the authentication of former factory, and customer worries potential quality problem.And once there be quality problem, easily produce unnecessary dispute.
3, install or dismantle inconvenience, when installing or dismantling, be easily mounted the equipment touching of tire, cause the damage of whole projector.
4,, while adopting coil spring antenna or tire tube valve antenna, because the difference of material is different with mounting means, as easy as rolling off a logly in the time producing, cause the inconsistent of launching effect; Meanwhile, spring antenna easily shakes, and tire tube valve makees antenna and is more easily subject to peripheral environment such as, the impact of marshy land, mud, causes the launching effect can be with environmental change, thereby causes the variation of launching effect.
5,, in TPMS use procedure, the in the situation that of in tire unsaturated vapor or without gas, this type of built-in projector is vulnerable to damage.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, a kind of cost-saving, easy installation and removal, launching effect is consistent, the life-span is long built-in automobile tire inflation pressure determining system are provided.
The object of the present invention is achieved like this: built-in automobile tire inflation pressure determining system, comprise wheel hub and projector, projector comprises PC board, power supply, micro-control unit, pressure sensor, temperature sensor and emitting antenna rear end are set in PC board, described PC board is connected on wheel hub, driving is brought in wheel hub in the emitting antenna setting that contacts with wheel hub before emitting antenna, and signal radiate by wheel hub.
On wheel hub of the present invention, mounting groove is set, PC board is connected with the wheel hub in mounting groove.
PC board of the present invention is connected with wheel hub with screw by registration mast, and registration mast is fixedly connected on the wheel hub in mounting groove.
PC board of the present invention arranges screened housing outward, and screened housing is connected with wheel hub.
The present invention is by being directly installed on built-in projector on tire inner wheel hub and avoiding the problems referred to above.The mode being installed on wheel hub can be varied; Can be to install, can also be directly the PC board of projector (PCBA) to be installed on wheel hub or wheel hub inside without shell with protecting sheathing.As a special case, on automotive hub, do the structure of a groove, the PCBA module of built-in projector has been taked after waterproof measure, directly be arranged on car body wheel hub by the cooperation of screw and registration mast, so not only facilitated installation but also improved safety performance, tire tube valve and launcher shell are not only economized, simultaneously, emitting antenna front end using car body wheel hub as built-in projector, in having saved the antenna front end (cost) of projector, make antenna with wheel hub and can not be subject to external environment condition as mud, the impact of marshy land on launching effect, fix because of material and the structure of wheel hub simultaneously, during as emitting antenna, also have conformability admirably, in addition, due to the present invention's description is that transmitter module is fixed on to the inner edge centre of wheel hub or is installed to wheel hub inside, in dismounting, when installing and using tire (be included in tire unsaturated vapor or without gas in the situation that), can not be broken or be damaged, played the protective effect to transmitter module.
