The outside for setting early capsul can be closely wrapped after the loading of load hole 30.Simultaneously for convenience of installation and removal, and guarantee set
If remaining to steadily rapidly stop in rotary state after flexible damping set 27.Subtract so being arranged the plane 25 of capsul in flexibility
At the load hole 30 of shake set 27, as shown in Figure 9.
In the present embodiment five, referring again to shown in Fig. 7,8, wherein on the surfaces externally and internally of the flexible damping set 27 of setting
It is evenly distributed several convex blocks outwardly protruded.Several the outer convex blocks being arranged on the specific outer surface by capsul
28, and it is set to cylindrical structure, Main Auto wheel has water mist or greasy dirt, in the mistake that tire pressure monitor 10 rotates
Cheng Zhong, droplet can fall off from the highest point of the outer convex block 28 of outer cylindrical；And water mist or greasy dirt also play lubricating action, subtract
Small frictional force between spherical tire pressure monitor 10 and automobile tire 1, to effectively guarantee the accuracy of monitoring data.Together
When several protrusions are equably arranged in capsul in appearance, and the inner surface of each protrusion self-sealing shell is outward by greatly extremely
It is small to gradually become smaller extension and obtain, in this way using the appearance face contact of the interior convex block 29 of capsul inner surface and capsul, thus soft
Property 27 convex block of shock-absorbing sleeve be in contact, will form netted gap, and flexible damping set 27 can have very big package to capsul
Power.During tire pressure detector rotation, due to wrapping up the presence of power, flexible damping set 27 and capsul will not occur relatively
Rotation, and the netted gap constituted between the two opposite can divulge information, and play the role of heat dissipation.
The technical principle that the tire pressure monitoring system with self power generation in the present invention is applicable in is as follows:
Spherical tire pressure monitor 10 with flexible damping set 27 is put into the wheel of automobile；Tire 1 and wheel hub 2
Space is far longer than the diameter of spherical tire pressure monitor 10.
When automobile starting, the revolving speed V of wheel is slowly become larger by zero.Assuming that wheel is low speed rotation when revolving speed V is less than V0
Dynamic state, 1 pair of tire spherical tire pressure monitor 10 apply instantaneous frictional force f (direction is clockwise, and with 1 inner surface phase of tire
Cut), the direction of inertia force is identical as the direction of motion, and it is total that the resultant force of inertia force and instantaneous frictional force becomes F；Due to F summation gravity
Under the action of, spherical tire pressure monitor 10, which can be close to 1 inner surface of tire, to be had the tendency that moving in a circle, and simultaneously in rotation:
As revolving speed V=0, spherical tire pressure monitor 10 is still in initial position A3；
When revolving speed V becomes larger, and is less than V0；F can always become larger；
When F it is total < partical gravity G2 when, spherical tire pressure monitor 10 can clockwise movement；
When moving to limiting altitude A4, F is total=partical gravity G2；Then spherical tire pressure monitor 10 can turn counterclockwise
It is dynamic, by initial position A3；And reach the limit of height B5；
When moving to limiting altitude B5, F is total=partical gravity G2；Then spherical tire pressure monitor 10 can turn clockwise
It is dynamic；
In conclusion when taking turns rotor speed V less than V0；Spherical tire pressure monitor 10 is in limiting altitude A4 and limiting altitude B5
Between do " simple harmonic motion ".
After automobile starting, it is assumed that when revolving speed V is greater than V0, wheel is height rotary state, 1 pair of tire spherical tire pressure prison
It surveys device 10 to apply instantaneous frictional force f (direction is clockwise, and tangent with 1 inner surface of tire), the direction and movement side of inertia force
To identical, it is total that the resultant force of inertia force and instantaneous frictional force becomes F；Under the action of F summation gravity, spherical tire pressure monitor 10
1 inner surface of tire, which can be close to, to be had the tendency that moving in a circle；And simultaneously in rotation:
As revolving speed V > V0, F is total > partical gravity G2, spherical tire pressure monitor 10 can clockwise movement；
By initial position B6, quadrantal points A7, quadrantal points B8 and when quadrantal points C9, F is total > partical gravity G2, so ball
Shape tire pressure monitor 10 can against 1 inner surface of tire and do " circular motion ".
When car deceleration stops its revolving speed V less than V0, spherical tire pressure monitor 10 is also to do " simple harmonic motion " at this time, is taken turns
Rotor speed slowly goes to zero；Final spherical shape tire pressure monitor 10 can be still in initial position A3.Lower casing has a plane 25, is conducive to
Spherical tire pressure monitor 10 is still in initial position A3.
Among the above, tire 1 in rotation, spherical tire pressure can in tire 1 side roll, do " revolution motion " around core wheel,
Under the action of frictional force and gravity, capsul can be done " spinning motion " around rotary shaft 22 and hemisphere 16 at this time, the pole N 18 and S
Coil on 31 opposite hemispheres body 16 of pole moves in a circle and generates electricity, and storage is in the battery.And battery passes through electronic component
Processing after give circuit board power supply.
It should be noted that above-described embodiment can be freely combined as needed.The above is only of the invention preferred
Embodiment, it is noted that for those skilled in the art, in the premise for not departing from the principle of the invention
Under, several improvements and modifications can also be made, these modifications and embellishments should also be considered as the scope of protection of the present invention.
