AI Technical Summary
The connection between the existing tire pressure sensor and the wheel hub is not stable enough, which makes it easy to shake or be impacted when the wheel rotates at high speed, affecting the accuracy of monitoring and potentially damaging the sensor.
A TPMS tire pressure monitoring device was designed, which includes a mounting base and a limiting component. The mounting base consists of a base body and a mounting groove, and the limiting component consists of a side plate, a fixing post, bolts and threaded holes. The sensor body is fixed by the threaded connection between the bolts and the fixing post. Combined with the design of rubber pads and buffer pads, the sensor is securely installed.
