Built-in tire pressure sensor

Abstract

The invention relates to a built-in tire pressure sensor which is mounted in an automobile tire and used for detecting the pressure and temperature inside the automobile tire. The built-in tire pressure sensor comprises a shell, a circuit board accommodated in the shell, a battery connected with the circuit board and a sensor body, wherein a locating component is arranged on the shell and is fixedly connected with the shell into a whole, a hole through which a fixing component penetrates to be connected with an inflating valve is formed in the locating component, and the inner wall surface, facing the inflating valve, of the locating component is a concave curved surface. When the tire pressure sensor is assembled, the inflating valve and the inner wall surface of the locating component are in tight fit, the fixing component penetrates through the hole in the locating component to be fixedly connected to the inflating valve; since the inner wall surface, acting on the inflating valve, of the locating component is a spherical surface, the tire pressure sensor can rotate relative to the inflating valve and is still in tight fit with the inflating valve; therefore, by adjusting the angle of the tire pressure sensor, the tire pressure sensor can come into tight fit with assembly interfaces of different tires without swinging or rotating so as to monitor temperature, pressure and the like in the tires in real time.

Description

technical field [0001] The invention relates to a tire pressure sensor, in particular to a built-in tire pressure sensor. Background technique [0002] In the European Union, the United States, etc., the tire pressure sensor is used as a standard configuration of the car. It detects the internal pressure and temperature of the vehicle tire in real time, and transmits the data to the driver in the cab to prevent the tire from being damaged due to insufficient / high air pressure, air leakage, tire damage, etc. If the surface temperature is too high, it may cause traffic accidents. [0003] There are two types of existing tire pressure sensors: built-in and external. The built-in tire pressure sensor is installed in the tire. If you want to disassemble it, you need to disassemble the tire first. Therefore, compared with the external tire pressure sensor, it can effectively prevent theft and is more convenient. Safety. In addition, the service life of the battery of the built-i...

Problems solved by technology

However, the assembly interface of different automobile tires may have different radians. The design of the existing built-in tire pressure sensor cannot meet the assembly requirements of the assembly interface of different radians, and the versatility of the product is not high.
