According to statistics, more than 70% of the traffic accidents on highways are caused by punctures, but less than 10% of drivers usually have the habit of actively checking the tire condition of vehicles. The abnormal problem of vehicle tires has always been the most difficult problem for all drivers. Therefore, the manufacturer has developed a tire pressure detecting device to detect the tire condition in a normal state, and immediately reminds the driver of the vehicle when the tire condition is abnormal, further Avoid accidents and casualties. The conventional tire pressure detecting device is mounted on a wheel frame of a vehicle tire. The tire pressure detecting device comprises a casing, a circuit board, a tire pressure sensor, a transmitting antenna, a processor and a a battery is provided, the bottom side of the housing is attached to the bottom of the wheel frame, the circuit board (such as a PCB) is received on the bottom side of the housing, the transmitting antenna and the processor and the The tire pressure sensor is soldered together on one side of the same large circuit board, the processor is electrically connected to the transmitting antenna and the tire pressure sensor, and the transmitting antenna and the tire pressure sensor are in position The battery is placed on the bottom side of the housing adjacent to the circuit board at the same level relative to one side of the board, the battery and the board being positioned on the same level relative to the bottom side of the housing. Although it is conventionally known that the tire pressure detecting device is mounted on the wheel frame of the vehicle tire to achieve the tire pressure detecting side effect, but another problem is extended, which is the circuit board of the conventional tire pressure detecting device. The transmitting antenna and the tire pressure sensor have directionality, because the transmitting antenna and the tire pressure sensor are on the same horizontal surface of the circuit board, so that the tire pressure sensor has a certain directionality on the installation and the transmitting antenna also has directionality. As a result, the problem of the orientation of the transmitting antenna and the wheel frame cannot be changed due to the limitation of the tire pressure sensor, thereby causing unstable reception and poor reception.
