[specific embodiment]
The explanation of relevant preferred embodiment of the present invention please be with reference to the scheme drawing of implementing of Fig. 1 demonstration.Tire 1 includes cover tire 11 and fixed part 13, is formed with space 12 in the tire between cover tire 11 and fixed part 13.In present embodiment, fixed part 13 is the wheel frame.In addition, fixed part 13 is provided with tire condition sensor 14 and power generation assembly 15, and wherein power generation assembly 15 is electrically connected with tire condition sensor 14, and power generation assembly 15 includes a fan 151 that is placed in space 12 in the tire.In present embodiment, fan 151 highly is a fixed part 13 (wheel frame) to half of the height of cover tire 11.In other embodiments, fan 151 highly also can be the height of the side that is lower than the wheel frame.
Fig. 2 display of tyre state sensing device 14 and power generation assembly 15 are mounted on the scheme drawing of fixed part 13, it is that display of tyre state sensing device 14, power generation assembly 15 and fan 151 are mounted on the fixed part 13, wherein tire condition sensor 14 joins with power generation assembly 15 next-door neighbours, and fan 151 is mounted on the power generation assembly 15.Might cause weight overbalance on the fixed part 13 because 151 groups in tire condition sensor 14, power generation assembly 15 and fan are located at one of fixed part 13 side, and influence the kinetic balance of tire.
Fig. 3 display of tyre state sensing device 14 and power generation assembly 15 are mounted on another scheme drawing of fixed part 13, tire condition sensor 14 can be built in the different ends of taking turns frame respectively with power generation assembly 15, wherein tire condition sensor 14 has electrical connection with power generation assembly 15, can provide power supply to tire condition sensor 14 for power generation assembly 15.
The above-mentioned power generation assembly 15 main rotations that see through fan 151 produce electric power.Because fan 151 is mounted on the power generation assembly 15 and is positioned at the tire space 12 of cover tire 11 and fixed part 13, so when tire 1 rotates, the fan 151 that is mounted on the power generation assembly 15 of fixed part 13 can produce relative motion with the air in space in the tire 12 and rotate, and then make power generation assembly 15 produce electric power, to provide electric power to tire condition sensor 14, make tire condition sensor 14 can when tire 1 rotates, just can detect the internal state of tire 1 at any time, so the detecting frequency of tire condition sensor 14 just can significantly improve.
Above-mentioned tire condition sensor 14 still can be detected temperature and other various states in the tire except can detecting the representative type tire pressure.The detailed description of relevant tire condition sensor 14 please be with reference to following explanation.
Fig. 4 shows the function block schematic diagram of above-mentioned tire condition sensor 14, tire condition sensor 14 comprises sensing meter 141, micro-control unit 142, forwarder 143, wherein tire condition sensor 14 receives and comes from the power supply that power generation assembly 15 is provided, operating.In addition, above-mentioned micro-control unit 142 is electrically connected with sensing meter 141 and forwarder 143 respectively.
In present embodiment, sensing meter 141 is made up of one or more sensing elements (Sensor), and it is to be used for pressure and temperature value in the sensing tire 1, to obtain the inner measured measuring values of at least one and these tires 1.142 energy of micro-control unit carry out signal conditioning to the measuring value that sensing meter 141 is obtained, and the result after will handling through forwarder 143 more then is sent to the receptor 16 of far-end.In present embodiment, forwarder 143 can be a transmission over radio module, and it is can see through result that RF-wise transmission micro-control unit 142 handled to receptor 16.In addition, above-mentioned receptor 16 can be mounted on the prime of the read out instrument of vehicle, that is, receptor 16 is behind the result that reception micro-control unit 142 is handled, may it be sent to a driving computer or control unit again and handle, the transmission display device shows the various states in the tire 1 then.
Fig. 5 shows the scheme drawing of another preferred embodiment of the present invention, and it is that display of tyre state sensing device 54 is installed on the fixed part 53 of tire 5 with power generation assembly 55, and fixed part 53 is a valve in present embodiment.Note that in the fan 551 of the power generation assembly 55 of present embodiment also to be placed in space 52 in the tire that when tire 5 rotated, fan 551 can produce relative motion with the air in space in the tire 52 and rotate, and makes power generation assembly 55 can produce electric power.
By above explanation as can be known, the invention provides a kind of tire pressure monitoring system that need not to use battery, it is to make power generation assembly produce electric power through the rotation of fan, make power generation assembly can provide electric power to tire pressure monitoring system, can avoid because of the battery in the tire produces with the too high situation of thrashing that makes of temperature, and can exempt the inconvenience that produces remove a tyre when changing battery.In addition, tire pressure monitoring system provided by the present invention is because the power supply abundance, thus can repay the tire pressure state constantly, to increase the frequency of detecting.
