Abstract
The utility model relates to a tire pressure monitoring sensor comprising an element box and a battery box which are separated. The element box and the battery box are respectively fixed on the inner surface of a rubber tire. The element box is electrically connected with the battery box. The electrical connection is flexible connection. With the design, the element box and the battery box of the sensor are adhered to the inner tire surface of the rubber tire, and are completely separated from an air valve. Therefore, air valve sealing rubber pad compressive deformation and loosening leakage caused by the centrifugal force during the rotation of a rim are prevented. With the separable design of the element box and the battery box, the volume of the unit is small, and the weight is light. The sensor can bear relatively high centrifugal force, such that sensor environment adaptability can be improved.
Description
Technical field
The utility model relates to system for monitoring pressure in tyre (Tire Pressure Monitoring System, TPMS), especially relates to the tire pressure monitoring sensor that is installed in the TPMS system on the tire.
Background technology
In system for monitoring pressure in tyre (Tire Pressure Monitoring System, TPMS), tire pressure monitoring sensor is installed on the motor tire, the pressure and temperature of monitoring tire, and the wireless receiver that is transmitted in the automobile.
Because tire pressure monitoring sensor can acutely be rocked with the high-speed operation of tire, so the reliable installation of tire pressure monitoring sensor is the problem of puzzlement industry always.
Tire pressure monitoring sensor is commonly integrated product at present, and namely all parts all concentrate in the housing.Aspect wheel rim assembling mode, tire pressure monitoring sensor is connected with tire tube valve mostly.Mainly contain two kinds of connection modes: buckle mouth and metal mouth.
In the buckle mouth connection mode, sensor body is connected locking by solid metal with screw with tire tube valve and is integral Metallic rod outer cladding one deck rubber.With wheel rim assembling place the buckle shape is being set, is passing the wheel rim mounting hole from the inboard with tire tube valve, acting on the mouth bar by applying certain pulling force, the tire tube valve rubber mouth is pulled out, the screens by the rubber layer setting is clamped in wheel rim.Sensor body by about two stressed wheel rim steel rings of being close to of journal stirrup.
The metal mouth connection mode adopts aluminum mouth bar, by screw the mouth bar is connected with sensor to be tightened to one.Be furnished with a seal gasket on the aluminum mouth bar, by being assembled on the wheel rim press seal pad to the wheel rim hole, the other end in wheel rim hole arrange a nut with the mouth rod locking in wheel rim.Sensor body equally by about two stressed wheel rim steel rings of being close to of journal stirrup.
The employed sensor of above dual mode all is that electronic devices and components chip and battery are positioned in the same sensor housing, causes the sensor combinations volume larger, and corresponding weight is heavier.In the wheel rim rotation process, because sensor weight is large, centripetal (centrifugal) power of bearing is also corresponding significantly to raise.And the tire High Rotation Speed produces centripetal (centrifugal) power size variation because of the variation of speed and surface evenness, causes the suffered radial weight of auto-tire valve constantly to change, and makes behind the installation of sensors locking unreliable, easily gets loose.
Another problem is, one side about two journal stirrups under larger centrifugal action, occur to the perk distortion of overturning, stress concentrates on the body junction of tire tube valve and sensor, even the situation that ruptures in the junction occurs.This may cause the gas leakage of tire on the one hand, can along with the rotation of wheel rim arbitrarily be overturn in tire, damage wheel rim and cause potential safety hazard after sensor comes off on the other hand.
Also have some other mounting meanss, for example by steel band sensor is fixed on the wheel rim, but the vibrations of this easy invar band and becoming flexible come off; Perhaps by glue sensor body is bonded on the wheel rim, because of humidity in the tire, the conditions such as temperature are comparatively abominable, and owing to be to be close to (steel or aluminium) on the wheel rim, the temperature during brake is transmitted so far soon, makes inner electronic component be in the condition of high temperature, cause the electronic component temperature to surpass sometimes its limit that can bear and cause damage, and after long-term the use, the glue bonding force can change, and causes to come off; In addition tire tube valve and sensor body plastic packaging are in the same place in addition, this sensor and inflating valve body can not turn round adjustment, and under the consistent condition of working accuracy, a kind of specification auto-tire valve can only be suitable for a kind of wheel rim of dimensions.Some sensors and tire tube valve capable of regulating are also arranged, but can't guarantee the stability of structure, can be loosening under long-term vibrations.
