The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with drawings and Examples.
Now please refer to Fig. 1,2 and 3, wherein show the tyre state sensor 10 of the first embodiment of the present invention.This state sensor 10 has a main body 12, an enclosing cover 14, a valve rod 16.
This main body 12 has an inner space in order to holding the sensing state (not shown), and this sensing state comprises that a sensor-specific integrated circuit ASIC (SensorApplication-Specific Integrated Circuit) is in order to induction pressure and temperature, power supply and a radio frequency (Radio Frequency such as battery; RF) forwarder in order to the tire condition that this ASIC responded to, is converted to the radio-frequency (RF) signal emission.Being skillful in present technique person can understand, and the receiving device in the arrangement vehicle can receive this radio-frequency (RF) signal of being launched, and to monitor the state of this tire.
14 of this main body 12 and this enclosing covers have a space 22 again, in order to the antenna 24 that holds this radio frequency transmitter.Shown in Figure 1, this antenna 24 is routed in this space 22, that is disposes along the upper surface that this main body 12 is defined, and is fixed by the location buckle 26 on this main body 12.Being skillful in present technique person can understand, and this antenna 24 can change its size according to the characteristic of this radio frequency transmitter, such as this antenna 24 length and diameter, and the outward appearance of wiring.Moreover, have a plurality of lines of rabbet joint 32 on this enclosing cover 14 in order to expose this antenna 24, to strengthen the electrical specification of this antenna.Have hole 34 combineds action on a plurality of coincidence pins 28 and this enclosing cover 14 on this main body 12 in addition, in order to enclosing cover is remained on the correct position.This enclosing cover 14 can be fixed on this body 12 by different ways, such as bolt, welding, and adhesion or the like.
Now please refer to Fig. 1 and Fig. 4, this main body 12 of this tyre state sensor 10 has two registration devices in addition, such as bolt 42 and tapped bore 36, in order to adjustably this sensor 10 is fixed on the wheel rim 40.This bolt 42 has a base portion 46 that strengthens and interior hexagonal nest and holds 44 ends that are positioned at this threaded portion.In the tapped bore 36 that this bolt 42 screws on this main body 12, and can pass this hole 36, adjust the position that this bolt 42 screws in by a hex spanner (hex wrench) 48.When this sensor 10 is fixed on this wheel rim 40, this valve rod 16 of this sensor 10 passes the valve opening on this wheel rim 40, and can be by a fixed by nut (not shown), and can adjust the position of this bolt 42 by hex spanner 48, make this base portion 46 of this bolt 42 prop up this wheel rim platform 52.As previously mentioned, just this tyre state sensor 10 firmly can be fixed on this wheel rim 40 by this valve rod 16 this two base portion 46 with this two bolt 42.
This main body 12 of this tyre state sensor 10 comprises two salients 56 in addition, is positioned at the both sides of this valve rod 16.When this tyre state sensor 10 is installed on this wheel rim 40, and this tire be need dismantle maintenance the time, and a maintenance instrument that inserts this tire might clash into this tyre state sensor 10.Can prevent that by this two salient 56 this service tools from directly clashing into the main body 12 of this sensor 10, and cushion the application force of this bump.Moreover this salient 56 also can hinder the end that this service tools clashes into this main body 12, and this valve rod 16 is caused bigger moment.
As previously mentioned, this tyre state sensor according to the present invention has the bolt of all right one way or the other adjustment, can with this valve rod combined action, this tyre state sensor can firmly be fixed on the wheel rim platform.This tyre state sensor has antenna and this salient of low profile again, is damaged by service tools in the time of can avoiding this tyre state sensor maintenance.
Though the present invention discloses with aforementioned preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this operator, without departing from the spirit and scope of the present invention, and when doing various changes and modification.Therefore protection scope of the present invention is when being as the criterion with claims.
