Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to thoroughly understand the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened is fully disclosed to those skilled in the art.
As shown in Figure 1, not powering off the composition schematic diagram of tyre pressure sensor alternative embodiment for one kind.Wherein, described continuous
Electric tyre pressure sensor includes: MCU, pressure sensor chip, radiofrequency launcher, antenna, rechargeable lithium battery, rectification and charging electricity
Road and charge coil.Wherein, the radiofrequency launcher is connect with the antenna, for being generated and transmitted by radiofrequency signal；It is described
MCU is connect with the pressure sensor chip, radiofrequency launcher and rechargeable lithium battery respectively, for controlling pressure signal
Acquisition and the generation and transmitting of radiofrequency signal；The rechargeable lithium battery is connected with rectification and charging circuit and charging in turn
Coil.Wherein, the charge coil is used to cut the magnetic field that wheel hub coil generates in electric car, to generate induced current；
The rectification and charging circuit charge for receiving the induced current after rectifying to it for rechargeable lithium battery.In addition,
The course of work of the utility model further includes, under the control of MCU, periodically by the tire pressure in the pressure sensor chip
Signal passes to radiofrequency launcher, is finally sent to the dress of the reception other than the utility model by the antenna being connected with radiofrequency launcher
It sets.
Among the above, described not power off tyre pressure sensor also to use while there is pressure sensor chip and temperature sensor
The sensing module of chip substitutes, and while detecting tire pressure, detects to the temperature of gas in air tube；Its benefit is,
When pressure sensor chip or temperature sensor chip alternative one break down, the number for the chip not broken down can be passed through
According to progress auxiliary judgment；The disadvantage is that cost is higher compared with the cost of single pressure sensor chip, and corresponding volume is bigger；Cause
This, single based on the considerations of being used in moment sensor chip stable performance and cost and volume, the present embodiment
Pressure sensor chip is monitored tire pressure.The MCU can also be substituted by single-chip microcontroller, ARM or CPU, comprehensively considered
On the basis of using effect and cost, MCU is selected to realize the control to coupled hardware in the present embodiment.It is described can
Charged lithium cells can also be substituted by Ni-Cr battery or nickel-metal hydride battery, wherein the nickel-metal hydride battery of equal volume is than Ni-Cr battery
With lithium battery weight, and Ni-Cr battery have memory effect, before charging, when the electricity of battery is not drained completely, it will
Cause the reduction of battery capacity；So having selected lighter in weight and the better lithium battery of charging performance in the present embodiment.Below will
The installation site and the course of work that do not power off tyre pressure sensor are illustrated in conjunction with the following drawings:
