Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
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.
The operation principle of the present invention is as follows：When automotive hub is rotated, the Permanentmagnet bar 8 in magnetoelectric transducer 1 is certain because having
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 line
Circle 3 does cutting magnetic line movement with Permanentmagnet bar 8, and 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 within 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.
