In order to ensure the safe driving of the automobile, it is very important to install a Tire Pressure Monitoring System (TPMS) on the automobile and monitor the parameters of the tire, such as the air pressure and the temperature, in real time. In the automobile tire pressure monitoring system, a corresponding monitoring device for monitoring the tire pressure is installed at the inflating valve hole of the rim of each tire. Under the state of driving or vehicle is static, the tire pressure monitoring device automatically monitors the pressure, temperature and other data of the tire in real time, and gives an alarm in time when the pressure and temperature of the tire are abnormal, thereby avoiding traffic accidents caused by tire faults and ensuring driving safety.

The angle between the tire pressure monitoring sensor and the nozzle rod in the current market is mostly unadjustable, and the application range of the tire pressure monitoring sensor is limited and can only be installed on a specific rim. In the design of the wheel rim, the angle of the valve rod relative to the sensor shell is in a variable range, and the structural characteristics of the rim are complex and diverse, so that the tire pressure monitoring sensor with the angle of the valve rod fixed relative to the sensor shell has the following limitations: in some cases, the bottom of the sensor housing can rub and interfere with the bottom of the rim well, thereby subjecting the housing to significant external forces or even rendering the sensor unmounted; in some cases, a large gap exists between the sensor shell and the bottom of the wheel rim groove, so that the wheel rim cannot effectively support the shell, the space occupied by the sensor shell is large, and the sensor shell is prone to cracking or falling off from the nozzle rod due to overlarge load when a vehicle runs at high speed or under other severe road conditions.

In order to solve the problems, the industry designs a structure that the angle of the nozzle rod can rotate relative to the sensor shell, so that when the tire pressure monitoring sensor is installed, the sensor shell can be just contacted with the bottom of the rim groove aiming at different rim designs, and the sensor shell can be sufficiently supported from the rim and cannot have too large interference with the rim.

However, when the automobile runs, the automobile inevitably passes through some uneven road sections, at the moment, tires vibrate up and down along with the automobile, and in the process, the sensor shell swings relative to the nozzle rod. The bottom of the sensor shell is in contact with the bottom of the rim groove, so that the sensor shell cannot swing downwards, but the sensor shell is not blocked by the rim groove, and therefore the sensor shell can swing upwards back and forth. In the long-time swing, the loosening of the internal device of the sensor is easily caused, and the sensor is broken down.
