Abstract
The utility model offers a launching device with a tire pressure inspecting system, wherein the launching antenna is arranged on the PCB board and parallel to the PCB board. The height of this launching device is greatly reduced, which will not be subject to the influence of the launching antenna length and can freely adopt the long antenna with higher gain so as to enhance the intensity of radio frequency.
Description
Technical field
The utility model relates to tire inflation pressure determining system, particularly its feedway.
Background technology
In the process of galloping, tire fault is that all drivers worry 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, in this ratio of the U.S. then up to 80%.How preventing to blow out becomes 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 the sensor that is placed in the tire, is used to detect the suffered pressure of tire, and sensor links to each other with emitting antenna by circuit, and sensor and interlock circuit are made a pcb board; Emitting antenna is vertically mounted on and is used to send detection signal on the pcb board.Receiving device is used to receive detection signal, so that remind the driver when tire pressure generation ANOMALOUS VARIATIONS.Emitting antenna adopts helical antenna usually.
Because the height of existing feedway depends on the length of emitting antenna, and narrow space in the tire, for avoiding running into tire inner wall, existing generating means has to adopt the lower short antenna of gain, and this has just seriously limited the raising of RF signal strength.
The utility model content
The purpose of this utility model is the feedway that provides a kind of tire inflation pressure determining system, and it has lower height, is convenient to adopt the higher vast of heaven line of gain as the intensity of emitting antenna with the raising radiofrequency signal.
The feedway of the tire inflation pressure determining system that the utility model provides, its emitting antenna is installed on the pcb board, and emitting antenna is parallel with pcb board.
Because emitting antenna is parallel with pcb board, and the height of feedway is greatly reduced, and no longer is subjected to the influence of emitting antenna length, can freely adopt the higher vast of heaven line of gain, improved the intensity of radiofrequency signal.
Description of drawings
Fig. 1 is the side-looking constructional drawing of prior art;
Fig. 2 is a side-looking constructional drawing of the present utility model;
Fig. 3 is plan structure figure of the present utility model.
The specific embodiment
The structure of existing feedway is seen Fig. 1, and emitting antenna is vertically mounted on the pcb board, and the length of antenna is seriously limited.
Embodiment one
See Fig. 2, emitting antenna 1 is parallel with pcb board 2, and its bottom bending 90 degree are connected on the pcb board 2.
Embodiment two
Boss is housed on the pcb board.Emitting antenna is contained on the boss, and parallel with pcb board.
Embodiment three
For further reducing the height of feedway, can on pcb board 2, open a gap.Emitting antenna 1 is arranged in breach, and is parallel with pcb board 2, as shown in Figure 3.Compare with embodiment one, two, present embodiment has avoided emitting antenna 1 to touch pcb board 2 on the one hand, to avoid the loss of radiofrequency signal; On the other hand, owing to make emitting antenna 1, reduced the suffered interference of emitting antenna 1 away from the components and parts on the pcb board 2.
Claims (2)
1. the feedway of tire inflation pressure determining system, its emitting antenna (1) is installed on the pcb board (2), it is characterized in that, and emitting antenna (1) is parallel with pcb board (2).
2. feedway as claimed in claim 1 is characterized in that, pcb board has breach on (2), and emitting antenna (1) is arranged in breach.
