The specific embodiment
Following conjunction with figs. and preferred embodiment describe technical scheme of the present invention, feature and advantage in detail:
Now see also Fig. 1, Fig. 2 and Fig. 3, wherein show Pneumatic vehicle tire state sensor 10 according to the embodiment of the invention.This state sensor 10 has a shell, and this shell comprises a base part 17 and an outer cover portion 11, and by a bolt 33 and a tapped bore 29 this outer cover portion 11 is fixed on this base part 17.This base part 17 has two compartments substantially, is respectively in order to hold an inductor circuit 25 and a battery tray 13 and the battery 15 that is placed in wherein.
The middle body of this base part 17 has a valve-rod cavity 51, and this valve-rod cavity 51 has an elongated hole 53, one tire valve rods 19 and can pass wherein.Has a block 55 in this tire valve rod 19.One end of this block 55 has the shoulder 56 of circular arc substantially, and this elongated hole 53 also has the shoulder 35 of a circular arc, so make when this tire valve rod 19 these elongated hole 53 of insertion, and by a nut 31 fixedly the time, this tire valve rod 19 also can be with respect to this base part 17, is the rotating shaft rotation with the shoulder 35 of this circular arc.Again, this nut 31 has a packing ring 38 in addition, and this nut 31 and this packing ring 38 have the dentation decorative pattern, so that this nut 31 can firmly be fixed on this tire valve rod 19, and the unlikely process of jolting owing to vehicle ' gets loose.
Consult Fig. 4 again, wherein show the section-drawing of the state sensor 10 of this Pneumatic vehicle tire.Because when this state sensor 10 is installed on the wheel of vehicle, the outer cover portion 11 of this shell is contact with a wheel rim platform (will in hereinafter explanation), so the surface of electronic component is installed on the circuit card of this sensor circuit 25 to be needed towards this outer cover portion 11, because powerful centrifugal action during vehicle ', and influence the stability of this sensor circuit 25 to avoid.This sensor circuit 25 mainly comprises an inductor application-specific integrated circuit ASIC (Sensor Application-Specific IntegratedCircuit) 47 again, wherein this ASIC can be the IBO1290 that LITEON company is sold, but wherein this inductor special IC 47 induction pressures and temperature.
Moreover, the personnel that are skillful in this skill will understand formerly that technology provides a kind of tire pressure inductor, have the inductor application-specific integrated circuit ASIC, and this kind tire pressure inductor is that this inductor ASIC and power brick are encapsulated in the shell, so when running down of battery, must change whole tire pressure inductor.Because this state sensor 10 according to the present invention has this battery tray 13 in order to fix this battery 15, and this outer cover portion 11 also is that detouchable is fixed on this base part 17, so this battery 15 can stably be fixed in this base part 17 by this battery tray 13, and is interchangeable.
As shown in Figure 5, the state sensor 10 of this Pneumatic vehicle tire can be fixed in by this tire valve rod 19 and a nut 21 and take turns on the frame 43.See also Fig. 4 and Fig. 5, the outer cover portion 11 of this state sensor 10 provides a circular-arc sunk surface 45 with projection, this curvature of circular-arc sunk part of circular-arc sunk surface 45 with projection is identical with the curvature of the wheel rim platform 42 of vehicle tyre, so when this state sensor 10 is installed in this when taking turns on the frame 43, this surface 45 can form wire with this wheel rim platform 42 of taking turns frame 43 and contact, and makes this state sensor 10 can more stably be fixed in this by this to take turns on the frame 43.
Please note and will understand the personnel that are skillful in this skill formerly technology provides a kind of tire pressure inductor, it provides a tire valve rod to have spherical block, so when with this tire valve rod of fixed by nut, need to fix this tire valve rod, increase the degree of difficulty that this tire pressure inductor is installed with speciality tool.Owing to the shoulder 56 that has a circular arc according to this tire valve rod 19 of this state sensor 10 of the present invention, so when fixing this tire valve rod 19 with this nut 31, the shoulder 56 of this circular arc can be avoided this tire valve rod 19 rotations, so can promptly this state sensor 10 be fixed in this and take turns on the frame 43.
Again, the inductor circuit 25 of this state sensor 10 is by a radio signal and a receiving device interaction, so that monitor this wheel, so this inductor circuit 25 need have an antenna 23 to send radio signal.As shown in Figures 2 and 3, this antenna 23 has crooked shape, along the surface configuration of the base part 17 of this state sensor 10.As Fig. 5 and shown in Figure 6, this antenna 23 is to be placed on the surface of this base part 17.When being taken turns on the frame 43 remove a tyre 41 by this, this tire 41 can move (as shown in Figure 6) with respect to this state sensor 10, and is unlikely and damages this antenna 23.
As previously mentioned, this state sensor 10 is in order to respond to the state in the air-inflation tyre, such as pressure and temperature, therefore the outer cover portion 11 according to this state sensor 10 of the present invention has two through holes 27 in addition, so that make this inductor circuit 25 can respond to the state of this tire.The personnel that are skillful in this skill will understand, and often be full of moisture content in air-inflation tyre.In conventional mounting in airtyred inductor, normally utilize the film of a special material, so that make inductor can respond to the pressure and the temperature of tire, and also can prevent in the circuit of this inductor of water intrusion, and the harmful effect of avoiding moisture content to produce circuit by this.Therefore, diameter according to this two through hole 27 in this state sensor 10 of the present invention is preferably below the 0.5mm, the surface has the ridge structure (not shown) simultaneously, makes this inductor circuit 25 can respond to the state of this tire, prevents that simultaneously moisture content from entering in this state sensor 10.
