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 utility model content
Technical problem to be solved in the utility model is, deformation can take place in the five metals helical antenna that overcomes prior art its circle spacing and helical angle in the process of galloping, influence the efficient of five metals helical antenna, gain and directivity, the defective that causes tire inflation pressure determining system not work like clockwork, a kind of external tire pressure monitoring projector of the PCB of being provided with antenna is provided, its PCB antenna of the external tire pressure monitoring projector of this PCB of being provided with antenna can not produce the variation of parameter and performance, 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 is provided with the PCB antenna, comprise pedestal, external tire pressure monitoring projector main circuit board, battery and outer cover, external tire pressure monitoring projector main circuit board and battery design respectively on pedestal, outer cover and pedestal are assembled together, and this external tire pressure monitoring projector that is provided with the PCB antenna also comprises the PCB antenna.
In technique scheme, as a kind of preferred version of the present utility model, described PCB antenna can be arranged on the external tire pressure monitoring projector main circuit board.
As another kind of preferred version of the present utility model, this external tire pressure monitoring projector that is provided with the PCB antenna also comprises pcb board and antenna bracket, pcb board is fixed on external tire pressure monitoring projector main circuit board or the pedestal by antenna bracket, and described PCB antenna can be arranged on the pcb board.
The shape of described PCB antenna can be to be curl shape or other shape.
The beneficial effects of the utility model are: the external tire pressure monitoring projector that is provided with the PCB antenna of said structure, owing to be that the attached copper printing process of adopting is set to PCB antenna (being PCB antenna) on external tire pressure monitoring projector main circuit board or the pcb board (being printed circuit board (PCB)), the copper sheet that promptly forms curl shape or other shape on external tire pressure monitoring projector main circuit board or pcb board is used as the PCB antenna, and the spacing of the thickness of the copper sheet on the pcb board, the width of cabling, cabling and the length of cabling have determined efficient, gain and the directivity of PCB antenna; The PCB antenna combines firmly with external tire pressure monitoring projector main circuit board or pcb board, although galloping is positioned at the external tire pressure monitoring projector on the auto-tire valve, its PCB antenna can not produce displacement or distortion yet and influence its performance.PCB antenna its manufacture craft in manufacturing process is simple, and the properties of product high conformity can improve the quality of products, and saves production cost.So, this external tire pressure monitoring projector that is provided with the PCB antenna, its PCB antenna can not produce the variation of parameter and performance, 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.
