Abstract
An automobile tire pressure monitoring system supply device mainly comprises a cover tire, a steel ring, an automobile brake disc, and a TPMS (Tire Pressure Monitor System) system mounted on the inner side of the steel ring, and a ring-shaped permanent magnet is mounted around the automobile brake disc. A solenoid is enwound on the surface of the ring magnet, is connected with a rectification voltage stabilizing circuit, and then supplies an air pressure temperature sensor in the TPMS system after passing the rectification voltage stabilizing circuit. The ring-shaped permanent magnet are divided into four main parts with the magnetic properties N, S, N, S sequentially. The utility model has the advantages of reasonable structure, convenience in installation, and the like.
Description
Technical field
The utility model relates to a kind of electric supply installation, especially a kind of device that is installed in the inner TPMS system power supply of doughnut that is used to.
Background technology
According to investigations, there is under-inflation in the tire of present 91% automobile or inflates excessive problem, and potential safety hazard is bigger.Known TPMS system is used to one of the most frequently used and effective equipment that detects air pressure of automobile tire and temperature at present now.Yet the air pressure induction installation of TPMS system is installed in the tyre rim inboard, adopt embedded lithium battery to be its power supply, but present lithium battery performance is general, is a serious problem to the TPMS system that keeps work for a long time.In case do not have electricity, then need change battery, at first will unload tire and change battery, this brings a lot of troubles and inconvenience for car owner's trip.It is few with the motor vehicle repair portion that changes the TPMS battery TPMS system to be installed in inside tires now in addition, can only in some special 4S shops, could accomplish, and this has more increased the trouble of TPMS replacing battery.
Summary of the invention
The purpose of the utility model provides and a kind ofly need not to unload tire, saves the energy, automobile tire pressure monitoring system electric supply installation easy for installation.
The utility model mainly comprises the brake disc of cover tire, steel ring, automobile and is installed in the inboard TPMS system of steel ring, around the brake disc of automobile annular permanent magnet is installed; At the magnet of the single magnetic of steel ring mounted on surface, twine solenoid on the magnet ring surface, solenoid is connected with regulator rectifier circuit, is othermohygrometer transducer power supply in the TPMS system behind regulator rectifier circuit.Four big parts such as said annular permanent magnet is divided into, magnetic is followed successively by N, S, N, S.
In running car, tire drive magnet and solenoid make the magnetic flux through solenoid constantly change with the rotation of tire with respect to annular permanent magnet rotation at a high speed; Thereby make in the solenoid magnetic flux+Φ and-Φ between checker; Producing induced current, is the pressure-temperature sensor power supply of TPMS system behind regulator rectifier circuit, detects the pressure and temperature of tire through the TPMS system; With the runflat accident, improve coefficient of safety.
Compared with present technology, the beneficial effect of the utility model is: rational in infrastructure, saving electric energy, easy for installation produces electric energy through electromagnetic induction and supplies power, effective energy savings, the service condition that facilitates.
Description of drawingsFig. 1 is the decomposition texture sketch of the utility model.
EmbodimentIn the decomposition texture sketch of the utility model shown in Figure 1, mainly comprise the brake disc 2 of cover tire, steel ring 1, automobile and be installed in the inboard TPMS system 3 of steel ring, around the brake disc of automobile annular permanent magnet 4 is installed; At the magnet 5 of the single magnetic of steel ring mounted on surface, twine solenoid 6 at magnet surface, solenoid is connected with regulator rectifier circuit 7, is othermohygrometer transducer power supply in the TPMS system behind regulator rectifier circuit.Four big parts such as said annular permanent magnet is divided into, magnetic is followed successively by N, S, N, S.
