Helical antenna is that outward appearance is made in metal forming is spiral antenna.Advantage is that performance of antenna is better, and shortcoming is large for taking up room, and need to increase fixation during use, and production, assembling conformability need to guarantee.
The utility model content
The utility model provides a kind of tire pressure monitor for solving on the existing tire pressure monitor antenna large technical matters that takes up room.
A kind of tire pressure monitor comprises: circuit card; Sensor, described sensor setting is on circuit card; Emitting antenna, described emitting antenna around sensor setting on circuit card.
Further, described emitting antenna roughly is " returning " font.
Further, described emitting antenna comprises the first coupling end and the second coupling end, described the first coupling end comprises the first fixed end, described the second coupling end comprises the second fixed end, described circuit card is provided with the first fixed orifice and the second fixed orifice, described the first fixed end is fixed in the first fixed orifice, and described the second fixed end is fixed in the second fixed orifice.
Further, described the first coupling end emitting antenna input end that is emitting antenna.
Further, described the first fixed end also comprises the anti-askew end that be arranged in parallel with circuit card, and described anti-askew end is close to circuit card.
Further, described emitting antenna surface increase coat of metal.
Further, described tire pressure monitor also comprises: battery, described battery is electrically connected described circuit card and sensor.
A kind of tire pressure monitor that the utility model provides is by the structure design mode that emitting antenna is arranged around sensor, the inner space of having saved as far as possible tire pressure detector.
Description of drawings
Fig. 1 is the scheme drawing of the utility model embodiment tire pressure monitor.
Fig. 2 is the scheme drawing of the utility model embodiment tire pressure monitor emitting antenna.
The specific embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Below in conjunction with drawings and Examples the utility model is described further.
To shown in Figure 2, a kind of tire pressure monitor that the utility model embodiment provides comprises such as Fig. 1:
Circuit card 10,
Sensor 20, described sensor 20 is arranged on the circuit card 10,
Emitting antenna 30, described emitting antenna 30 is arranged on the circuit card 10 around sensor 20, roughly is " returning " font.Improved so as far as possible the space availability ratio of tire pressure monitor.
A kind of tire pressure monitor that the utility model provides is by the structure design mode that emitting antenna 30 is arranged around sensor 20, the inner space of having saved as far as possible tire pressure detector.The each several part of emitting antenna 30 is designed to regular profile, can reduce production difficulty, can keep homogeneity of product, and is convenient to the examination and test of products, and the product supply of material time do not want independent packaging, is easy to use in enormous quantities.
The tire pressure monitor principle of work that the utility model embodiment provides is: the tire pressure information exchange that sensor 20 is tested is crossed the high frequency carrier transmit to the space, by the receiver receiving demodulation that disposes on the car.Wherein the high-frequency emission partial design is difficult point, and now along with chip integration is more and more higher, peripheral emitting antenna 30 has been the most critical parts.
Described emitting antenna 30 comprises the first coupling end 31 and the second coupling end 32, described the first coupling end 31 is the emitting antenna input end of emitting antenna 30, described the first coupling end 31 comprises the first fixed end 311, described the second coupling end 32 comprises the second fixed end 321, described circuit card 10 is provided with the first fixed orifice 11 and the second fixed orifice 12, described the first fixed end 311 is fixed in the first fixed orifice 11, and described the second fixed end 321 is fixed in the second fixed orifice 12.The first fixed end 311 is fixed on the first fixed orifice 11 neutralization the second fixed end 321 and is fixed on fixing means in the second fixed orifice 12, can take the modes such as welding or grafting.
Described the first fixed end 31 also comprises the anti-askew end 312 that be arranged in parallel with circuit card 10, and described anti-askew end 312 is close to circuit card 10, can prevent emitting antenna 30 crooked phenomenon in use, and better FRPA-Fixed Radiation Pattern Antenna 30 is on circuit card 10.
The first coupling end 31 is different owing to shape with the second coupling end 32, so the structure design of emitting antenna 30 satisfies assembling mistake proofing mechanism; Emitting antenna 30 is not yielding in producing the supply of material, and packing requirements is low, is easy to disassemble; The fitting process of emitting antenna 30 does not need independent frock, and the plug-in unit welding can be finished at same station with assembling, and is time saving and energy saving.
A kind of tire pressure monitor that the utility model embodiment provides also comprises:
