Background technology
In vehicle travel process, tire pressure on-line real-time measuremen device is very necessary.Existing tire pressure inspection
Device is surveyed to power using battery.It has the disadvantage that battery will often be changed.
The content of the invention
The purpose of this utility model is to provide a kind of centrifugal force magneto-electric tire pressure detection circuit electric supply installation, using magnetoelectricity
Sensor, rectification circuit and storage capacitor detect that a kind of centrifugal force magneto-electric tire pressure that circuit is powered detects circuit to tire pressure
Electric supply installation.The electric supply installation of this centrifugal force magneto-electric tire pressure detection circuit can effectively replace battery, and circuit is simple.
The utility model includes magnetoelectric transducer, bridge rectifier and storage capacitor, and the technical scheme used is：
Magnetoelectric transducer is connected with bridge rectifier, and bridge rectifier is connected by storage capacitor with mu balanced circuit, mu balanced circuit
Direct voltage output wire is set；Permanentmagnet bar is fastened on one in magnetoelectric transducer by spring in the magnetoelectric transducer

Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
In figure：1. magnetoelectric transducer, 2. springs, 3. coils, 4. copper pipes, 5. bridge rectifiers, 6. storage capacitors,
7. mu balanced circuit, 8. Permanentmagnet bars, 9. direct voltage output wires.
Embodiment
Shown in Fig. 1：Magnetoelectric transducer 1 is connected with bridge rectifier 5, and bridge rectifier 5 is by storage capacitor 6 and surely
Volt circuit 7 is connected, and mu balanced circuit 7 sets direct voltage output wire 9；Permanentmagnet bar 8 passes through spring 2 in the magnetoelectric transducer 1
It is fastened on one end in magnetoelectric transducer 1, the movable set of the Permanentmagnet bar 8 copper pipe 4 that the other end is fixed in magnetoelectric transducer 1
Interior, the wound around coil 3 of the surrounding of Permanentmagnet bar 8 is fixed on the copper periphery of pipe 4；Multiple through holes are distributed with the copper surrounding of pipe 4.
Operation principle of the present utility model is as follows：When automotive hub is rotated, the Permanentmagnet bar 8 in magnetoelectric transducer 1 is because having
Certain weight and made a concerted effort by the centrifugal force produced by vehicle wheel rotation and self gravitation, spring 2 produces stretching motion so that
Coil 3 is set to do cutting magnetic line movement with Permanentmagnet bar 8, coil 3 produces induced voltage.
Under wheel at the uniform velocity rotating condition, when magnetoelectric transducer 1 rotates to the surface of wheel, due to the weight of Permanentmagnet bar 8
Power and centrifugal force are in opposite direction, and the power that spring 2 is subject to is minimum；When magnetoelectric transducer 1 rotates to the underface of wheel, due to forever
The gravity of bar magnet 8 is identical with centrifugation force direction, and the power that spring 2 is subject to is maximum.So in wheel rotary course, spring 2 by
Power be always change, coil 3 is doing cutting magnetic line movement always with Permanentmagnet bar 8, therefore magnetoelectric transducer 1 has electricity always
Lotus is produced, and this electric charge is stored in storage capacitor 6 after the rectification of bridge rectifier 5, after the voltage stabilizing of mu balanced circuit 7, through direct current
Press output lead 9 to export a burning voltage, used for tire pressure detection circuit.
Under the non-at the uniform velocity rotating condition of wheel, the Permanentmagnet bar 8 in magnetoelectric transducer 1 is by the centrifugation produced by vehicle wheel rotation
Power is continually changing, and the power that spring 2 is subject to also is always change, and coil 3 is doing cutting magnetic line fortune always with Permanentmagnet bar 8
It is dynamic, therefore magnetoelectric transducer 1 has electric charge generation always, this electric charge is stored in storage capacitor 6 after the rectification of bridge rectifier 5
In, after the voltage stabilizing of mu balanced circuit 7, a burning voltage is exported through direct voltage output wire 9, is used for tire pressure detection circuit.
Because Permanentmagnet bar 8 is connected by spring 2, it is enclosed in addition in the copper body of pipe 4, its telescopic movable scope is protected all the time
Hold at the center of coil 3.
So, it is real using the centrifugal force of Permanentmagnet bar 8 using magnetoelectric transducer 1, bridge rectifier 5 and storage capacitor 6
The power supply to tire checking circuit is showed.
