Abstract
The utility model relates to a built-in tire pressure monitoring transmitter with a gas nozzle and a wheel drum as antennas, which belongs to the field of tire pressure detection systems. The coil spacing and the spiral angle of the existing hardware spiral antennas in the automobile tire running at a high speed can be deformed to affect the efficiency, gain and directionality of the hardware spiral antennas, so that the tire pressure detection system can not operate accurately. The built-in tire pressure monitoring transmitter comprises a transmitter shell, a main transmitter circuit board and a screw connecting the antenna output end of the main circuit board and a gas nozzle, the screw also connects the main transmitter circuit board and the transmitter shell, the built-in tire pressure monitoring transmitter also comprises a gas nozzle functioning as a transmitter antenna and a wheel drum connected with the gas nozzle, and the gas nozzle connected with the screw is also assembled with the transmitter shell. Since the gas nozzle and the wheel drum are used as the antennas, the utility model improves the radio-frequency signal transmitting efficiency of antennas, thereby ensuring that the tire pressure detection system can operate accurately.
Description
Technical field
The utility model relates to the tire inflation pressure determining system field, particularly relates to a kind of built-in tire pressure monitoring transmitter that valve and wheel hub is made as antenna.
Background technology
Automobile is in the process of running at high speed, and tire fault is that all drivers worry and the most difficult prevention the most, also is the major reason that sudden traffic hazard takes place.According to statistics, the traffic hazard that takes place on Chinese highway has 70% to cause by blowing out, and in the U.S., this ratio is then up to 80%.How to prevent to blow out and become an important topic of safe driving.And the tyre pressure that maintains the standard travels and in time find that tire gas leakage is to prevent the key of blowing out.Under this background, tire inflation pressure determining system arises at the historic moment.Tire inflation pressure determining system is also referred to as TPMS (Tire Pressure Monitoring system), be mainly used in when running car tire pressure monitored automatically, to have a flat tire and infrabar report to the police.This system is made up of emitter and receiving trap.Emitter comprises sensor and the emitting antenna that is placed in the tire, be used to detect the suffered pressure of tire, sensor links to each other with emitting antenna by circuit, sensor and interlock circuit are made a pcb board (being printed circuit board (PCB)), emitting antenna is vertically mounted on the pcb board, is used to send detection signal.The receiving trap that is arranged in the pilothouse is used to receive detection signal, so that remind driver, the generation that tries to forestall traffic accidents when tire pressure generation ANOMALOUS VARIATIONS.
Prior art generally adopts the five metals helical antenna as the emitting antenna in the emitter.Adopting the five metals helical antenna may be a kind of reasonable selection, it can enlarge the angle that transmits and receives, overcome quiet dynamic blind spot effectively, the straight warp (D) of five metals helical antenna, the number of turns (N), circle spacing (S), helix angle (α) have determined efficient, gain and the directivity of antenna.In the doughnut that runs up, deformation can take place in circle spacing, the helix angle of five metals helical antenna, thereby efficient, gain and the directivity of five metals helical antenna have been influenced, cause tire inflation pressure determining system not work like clockwork, can not monitor automatically tire pressure like clockwork and to have a flat tire and infrabar report to the police.In the process of making the five metals helical antenna, its processes is had relatively high expectations, the number of turns (N), circle spacing (S), the bad control of helix angle (α), and the consistency of performance of the product of making is bad.
The antenna of built-in tire pressure detection emitter generally is enclosed in inside tires with main circuit board, and antenna volume can not be done greatly, otherwise will influence the performance of antenna; And the less words of antenna volume, when passing the rubber for tire layer by the radiofrequency signal of antenna emission, the rubber for tire layer is very big to the attenuation of radiofrequency signal, the receiving trap that causes being arranged in the pilothouse can not receive detection signal like clockwork, thereby tire inflation pressure determining system can not be worked like clockwork, can not monitor automatically tire pressure like clockwork and to have a flat tire and infrabar report to the police.
The utility model content
Technical problem to be solved in the utility model is, overcome the not enough defective of radio-frequency (RF) signal strength of antenna emission of the built-in tire pressure detection emitter of prior art, a kind of built-in tire pressure monitoring transmitter that valve and wheel hub is made as antenna is provided, this built-in tire pressure monitoring transmitter utilizes valve and the antenna of the wheel hub that links to each other with valve as transmitter, because valve exposes in the tire outside with the wheel hub that links to each other with valve, can avoid the decay of tire to the radiofrequency signal of antenna emission; Again because valve links to each other with wheel hub, wheel hub also can be used as the part of antenna, so just increased antenna volume greatly, improved the emission efficiency of antenna emitting radio frequency signal, thereby can guarantee that tire inflation pressure determining system works like clockwork, like clockwork tire pressure is monitored automatically and, when tire pressure generation ANOMALOUS VARIATIONS, remind driver, the generation that tries to forestall traffic accidents having a flat tire and infrabar is reported to the police.
The technical scheme that its technical matters that solves the utility model adopts is: the built-in tire pressure monitoring transmitter that valve and wheel hub is made as antenna, comprise launcher shell, transmitter main circuit board and be used for the screw that the main circuit board antenna output end links to each other with valve, screw links together transmitter main circuit board and launcher shell, this built-in tire pressure monitoring transmitter has also comprised the valve and the wheel hub that links to each other with valve of the antenna effect of transmitter, and the valve and the launcher shell that link to each other with screw are assembled together.
The beneficial effects of the utility model are: the built-in tire pressure monitoring transmitter that valve and wheel hub is made as antenna of said structure, because this built-in tire pressure monitoring transmitter has also comprised the valve and the wheel hub that links to each other with valve of the antenna effect of transmitter, the valve and the launcher shell that link to each other with screw are assembled together, this built-in tire pressure monitoring transmitter utilizes valve and the antenna of the wheel hub that links to each other with valve as transmitter, because valve exposes in the tire outside with the wheel hub that links to each other with valve, can avoid the decay of tire to the radiofrequency signal of antenna emission; Again because valve links to each other with wheel hub, wheel hub also can be used as the part of antenna, so just increased antenna volume greatly, its volume is more than wanting big at the antenna of transmitter inside, improved the emission efficiency of antenna emitting radio frequency signal, thereby can guarantee that tire inflation pressure determining system works like clockwork, like clockwork tire pressure is monitored automatically and to have a flat tire and infrabar report to the police, when tire pressure generation ANOMALOUS VARIATIONS, remind the driver, the generation that tries to forestall traffic accidents, and reduce the production technology of making antenna, save production cost.
