Description
Technical field
The utility model relates to a kind of tire sensor and improves structure, specifically, relates to a kind of structure after improveing on the existing tire parameter detecting sensor.
Background technology
The charge pressure of the security of vehicle ' and fuel economy and tire is closely related.The too high or too low vehicle performance that all will make of charge pressure reduces, and tyre life shortens, and environment is had a negative impact.In real time monitoring tire pressure and in time reporting to the police to the driver when pressure abnormity can make the driver grasp the working condition of tire at any time, and control tire and vehicle are worked in the best way, improve the rideability of vehicle.Tire pressure sensing is the important composition parts of automatic monitoring of tire pressure and warning system, is the key factor of decision systems performance.
Existing sensor mainly is made up of a main body 12, an enclosing cover 14 and a valve rod 16.Valve rod 16 is installed on the rim for automobile wheel.
This main body 12 has an inner space in order to hold the sensing state (not shown).This sensing state comprises a sensor-specific integrated circuit ASIC, in order to induction pressure and temperature, a power supply and a radio frequency transmitter such as battery, in order to the tire condition that ASIC responded to, is converted into the radio-frequency (RF) signal emission.
14 of this main body 12 and this enclosing covers have a space 22, in order to the antenna 24 that holds this radio frequency transmitter.As shown in the figure, this antenna 24 is routed in the space 22, and promptly a upper surface that is defined along this main body 12 disposes, and is fixed by the location buckle 26 of this main body 12.Knowing those skilled in the art can understand, and antenna 24 can change its size according to the characteristic of radio frequency transmitter, as this antenna 24 length and diameter, and the outward appearance of wiring.Have a plurality of slits 32 on this enclosing cover 14 in order to expose antenna 24, to strengthen the electrical specification of antenna 24.Have hole 34 actings in conjunction on a plurality of coincidence pins 28 and the enclosing cover 14 on the main body 12 in addition, in order to enclosing cover is held in the correct position.Enclosing cover 14 can be fixed on the body 12 by multiple different form, such as welding, bolt and mount technology etc.
A complete tire parameter surveillance includes sensor and receiving trap two parts, and sensor is with detected tire parameters, and for example tyre temperature, tire pressure etc. are converted into the radio-frequency (RF) signal emission.The receiving trap that is loaded in the vehicle can receive the state that this radio-frequency (RF) signal is monitored tire.Present tire parameter surveillance can be divided into the surveillance of one-way communication and the surveillance of two-way communication haply.
The surveillance of so-called one-way communication, the sensor that refers in the surveillance only can be launched signal, and receiving trap also only can receive signal.Obviously, such one-way communication surveillance can only be accomplished regularly monitoring tyres parameters, i.e. setting-up time, and such as per 30 minutes, signal of sensor emission.Along with the raising day by day of people's living standard, to proposing higher requirement to vehicle.The pattern of above-mentioned timed sending can't provide instant security monitoring to the user, improve security performance, can only shorten the emission duration of sensor.But the shortening emission duration can make that again the power consumption of sensor significantly increases.Moreover anyway shorten, total life period can not reach the purpose of instantaneous safety monitoring at interval between the twice emitting in theory.Like this, receiving trap can't judge accurately whether sensor has fault.For example, sensor normally sends signal, and receiving trap does not receive that receiving trap can only be judged to be sensor at this moment problem, sends warning, causes the unnecessary trouble of user.Possible user continues out a period of time, surpasses the sensor transmission time interval, and sensor sends signal once more, and receiving trap has received and shown normal fully.The user can't be relieved fully to this security monitoring.
The surveillance of so-called two-way communication, the sensor that refers in the surveillance can be launched the tire parameter signal to receiving trap, and receiving trap also can be given sensor by emission instruction signal.So, when receiving trap is received the tire parameter signal that sensor sends over, note abnormalities after relatively, then send instruction and send the tire parameter signal at once once more, thereby reached the purpose of immediately monitoring and accurately judge to sensor with system internal standard value.But this moment, the technical matters of existence was, the tire parameter signal that sensor sends, and the success ratio that receiving trap receives must be high, otherwise receiving trap is not received signal, needs instruction sensor to send out again, and sensor has sent, receiving trap do not receive again, then instruction sensor once more.So repeatedly, make the power consumption of sensor sharply increase, the electric energy consume is excessive.
