Structure and apparatus for tire pressure monitoring

An apparatus for tire pressure monitor, comprising:

• a case having a receiving space and a connecting part, wherein the connecting part is disposed on an outside of the case;
• a gas nozzle unit having one end thereof movably connected to the connecting part;
• and
• a structure for tire pressure monitoring, disposed in the receiving space, comprising:
• a main body having a first part and a second part, wherein the first part is disposed on an upper side of the second part, wherein the first part and the second part are not on the same plane;
• a signal processing unit disposed at one side of the first part of the main body, wherein the signal processing unit is provided with a wireless emitter, a processing unit connected to the wireless emitter, and a first circuit board, wherein the wireless emitter and the processing unit are disposed on one side of the first circuit board;
• a sensing unit disposed on the top side of the second part of the main body, wherein the sensing unit is provided with at least one sensor and a second circuit board, wherein the at least one sensor is disposed on one side of the second circuit board and connected to the processing unit disposed on the first circuit board;
• and
• a power unit disposed on a bottom side of the second part corresponding to the sensing unit, wherein the power unit is connected to the signal processing unit and the sensing unit to provide power.
