Description
Technical field
The utility model relates to the tire inflation pressure determining system field, particularly relates to a kind of external tire pressure monitoring projector that pedestal 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 chaufeurs are worried and the most difficult prevention the most, also is the major reason that sudden traffic accident takes place.According to statistics, the traffic accident that takes place on Chinese express 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), is mainly used in when running car tire pressure is monitored automatically, and tire flat and infrabar are reported to the police.This system is made up of feedway and receiving device.Feedway 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 device that is arranged in the operator's compartment 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 feedway.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), helical angle (α) have determined efficient, gain and the directivity of antenna.In the motor tire of high-speed operation, deformation can take place in circle spacing, the helical 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 like clockwork tire pressure be monitored automatically and tire flat and infrabar be reported 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 helical angle (α), and the consistency of performance of the product of making is bad.
The external tire pressure of prior art detects the general and main circuit board of the antenna of projector and connects together, because it is to be screwed on the valve of tire that external tire pressure detects projector, volume can not be done greatly, thereby antenna volume also can be very little, too small volume can influence the performance of antenna and the efficient of emitting radio frequency signal, the receiving device that causes being arranged in the operator's compartment can not receive detection signal like clockwork, thereby tire inflation pressure determining system can not be worked like clockwork, can not like clockwork tire pressure be monitored automatically and tire flat and infrabar be reported to the police.
The utility model content
Technical problem to be solved in the utility model is, the external tire pressure that overcomes prior art detects the not enough defective of RF signal strength of the antenna emission of projector, a kind of external tire pressure monitoring projector that pedestal and wheel hub is made as antenna is provided, this external tire pressure monitoring projector utilizes pedestal, with pedestal cranked tire valve that is assembled together and the wheel hub that links to each other with cranked tire valve as antenna, because cranked tire valve exposes in the tire outside, cranked tire valve links to each other with wheel hub, wheel hub also can be used as the part of antenna, so just increased antenna volume widely, improved the efficient 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 tire flat and infrabar are reported to the police, when tire pressure generation ANOMALOUS VARIATIONS, remind driver, the generation that tries to forestall traffic accidents.
The technical scheme that its technical matters that solves the utility model adopts is: the external tire pressure monitoring projector that pedestal and wheel hub is made as antenna, comprise projector main circuit board, battery and outer cover, this external tire pressure monitoring projector also comprised the antenna effect of projector pedestal, with pedestal cranked tire valve that is assembled together and the wheel hub that links to each other with cranked tire valve, projector main circuit board and battery are assemblied in the pedestal respectively, outer cover and pedestal are assembled together, and the antenna output end of projector main circuit board connects as one by screw and pedestal.
The beneficial effects of the utility model are: the external tire pressure monitoring projector that pedestal and wheel hub is made as antenna of said structure, because this external tire pressure monitoring projector has also comprised the pedestal of the antenna effect of projector, with pedestal cranked tire valve that is assembled together and the wheel hub that links to each other with cranked tire valve, projector main circuit board and battery are assemblied in the pedestal respectively, outer cover and pedestal are assembled together, the antenna output end of projector main circuit board connects as one by screw and pedestal, this external tire pressure monitoring projector utilizes the antenna of pedestal as projector, because pedestal is screwed on the cranked tire valve, cranked tire valve is connected as one with wheel hub again, and projector is pedestal, with pedestal cranked tire valve that is assembled together and the wheel hub that links to each other with cranked tire valve as antenna; Again because cranked tire valve exposes in the tire outside, cranked tire valve links to each other with wheel hub, wheel hub also can be used as the part of antenna, so just increased antenna volume widely, improved the efficient 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 tire flat and infrabar are reported 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.
