The sensor adopts the movable sensor housing and can automatically adjust the movement of the sensor housing through the rotation of the nut, thereby realizing automatic mounting and positioning and satisfying the requirements for product assembly. Furthermore, the sensor has reliable sealability.

Description

Tire pressure monitoring sensor
Technical field
The utility model relates to a kind of sensor, refers to a kind of tire pressure monitoring sensor especially.
Background technology
Vehicle tyre pressure supervisory system (TPMS) is by installing highly sensitive sensor on each tire, data such as the pressure of real time monitoring tire, temperature under driving or static state, and be transmitted into the built-in receptor of central monitor by wireless mode, central monitor shows above-mentioned data or reminds the motorist with forms such as buzzings on telltale, and change at tire flat and pressure and to surpass safe thresholding (this threshold value can be set by telltale) time and report to the police, with guarantee driving safety.
The sensor that uses roughly has two kinds at present, and a kind of is non-active type sensor, and promptly sensor outer housing is fixed, and can not move, and so when mounted, is difficult to adapt to the wheel hub requirement of different size; Another kind is the active type sensor, the sensor outer housing of this sensor can be rotated around rotary middle spindle, though can satisfy the installation requirements of different size wheel hub like this, but this sensor can not automatically regulating, and when vehicle ', under the wheel hub action of centrifugal force, be upturned easily, thereby influence the loading and unloading of tire and the safety of tire.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, a kind of tire pressure monitoring sensor is provided, this sensor adopts movable sensor outer housing, and the activity that can come the automatically regulating sensor outer housing by the turn nut, thereby can realize automatic installing and locating, satisfy the requirement of assembled product and the failure-free leak tightness is arranged after assembling.
In order to solve the problems of the technologies described above, scheme of the present utility model is as follows:
A kind of tire pressure monitoring sensor, comprise a sensor outer housing, one screw rod, one with the screw rod nut engaged, one is connected to the packing seal on the hub installing hole, described sensor is fixedly arranged in the sensor outer housing, described screw rod one end passes sensor outer housing, sensor outer housing is movably connected on the described screw rod by a rotary middle spindle, described screw rod port is installed with a tire tube valve bar, described sensor outer housing is provided with a sliding bevel, described tire tube valve bar is connected on the sliding bevel of sensor outer housing and forms a contact wire, perpendicular to described sliding bevel and the slip diametric plane by described contact wire between rotary middle spindle and shell hub binding face.
Further, an end of described tire tube valve bar contact sliding bevel is circular-arc, is socketed with a dust cap on the described screw rod.
Further, be provided with a circular arc pad between packing seal and the sensor outer housing, described pad and sensor outer housing closed contact.Mate mutually on the circular arc limit of the shape of circular arc pad and sensor outer housing, thereby fit together closely, like this, has not only increased the support strength of pad, and can support packing seal and wheel hub surface and fit tightly the leak tightness that guarantees its junction.
Technique effect of the present utility model is: because this sensor is built-in sensor, so when the end with screw rod passes hub installing hole, one nut is screwed on the screw rod, when nut tightens up, screw rod is subjected to the effect of wheel hub can produce one along the application force on the screw stem line direction, thereby make the sliding bevel that is provided with on the tire tube valve pole pair that is fixed in the screw rod port and the sensor outer housing that it contacts produce an application force, because sensor outer housing is movably connected on the screw rod by a rotary middle spindle, also be positioned between rotary middle spindle and the shell hub binding face (being sensor outer housing and wheel hub binding face) perpendicular to sliding bevel simultaneously by the slip diametric plane of contact wire (being that the tire tube valve bar is connected to formed contact wire on the sliding bevel), so just can guarantee that the tire tube valve bar can produce the downward application force application force of shell hub binding face direction (promptly to) to sensor outer housing, force sensor outer housing to move down, by constantly tighten up nut just can be constantly with sensor outer housing to pressing down, thereby sensor outer housing and wheel hub are close to satisfy the convenience of tire loading and unloading.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model.
Fig. 2 is that the utility model is installed in the scheme drawing on the wheel hub.
The specific embodiment
Now with the specific embodiment the utility model embodiment is described in further details in conjunction with the accompanying drawings:
Shown in Figure 2 as Fig. 1, a kind of tire pressure monitoring sensor, comprise a sensor outer housing 8, one screw rod 9, be socketed with a dust cap 1 on the screw rod 9, one with screw rod 9 nut engaged 2, one is connected to the packing seal 4 on the hub installing hole 10, sensor 7 is fixedly arranged in the sensor outer housing 8, screw rod 9 one ends pass sensor outer housing 8, sensor outer housing 8 is movably connected on the screw rod 9 by a rotary middle spindle 11, screw rod 9 ports are installed with a tire tube valve bar 6, one end of tire tube valve bar 6 contact sliding bevels 12 is circular-arc, sensor outer housing 8 is provided with a sliding bevel 12, tire tube valve bar 6 is connected to and forms a contact wire on the sliding bevel 12 of sensor outer housing 8, perpendicular to described sliding bevel 12 and the slip diametric plane by described contact wire between rotary middle spindle 11 and shell hub binding face 13.Be provided with a circular arc metallic gasket 5 between packing seal 4 and the sensor outer housing 8, pad 5 and sensor outer housing 8 closed contacts.
Concrete principle of the present utility model is: 9 pairs of tire tube valve bars 6 of screw rod have directed force F when nut screws 1, the sliding bevel 12 that the arc surface of tire tube valve bar 6 afterbodys acts on sensor outer housing 8 under the effect of this power produces one perpendicular to sliding bevel 12 and pass the power F of contact point 2, in theory of mechanics, as long as power F 2Be positioned at rotary middle spindle 11 deflection wheel hub binding faces 13 these directions, then power F 2Will inevitably apply the power to wheel hub binding face 13 directions to sensor outer housing 8, sensor outer housing 8 is at F 2Effect under be axle center left-hand revolution ω with rotary middle spindle 11, cause sensor outer housing 8 and wheel hub 14 to be close to satisfy tire and load and unload easily.At F 2Effect down can also prevent that tire sensor outer housing 8 when high speed revolution is subjected to the problem of centrifugal action perk.The design of the circular arc faying face of sensor outer housing 8 and metallic gasket 5 in addition, satisfy sensor outer housing 8 rotation requirements, sensor outer housing 8 is combined closely with the arc surface of metallic gasket 5 increases the support strength of metallic gasket, can support packing seal and wheel hub surface and fit tightly its leak tightness of assurance.
