The invention provides a tire pressure sensor. The tire pressure sensor comprises a shell, a PCBA installed in the shell, a power supply device installed in the shell and electrically connected with the PCBA, and an antenna connected to the PCBA. The antenna is arranged on the PCBA in a surrounding mode, and the antenna is arranged on the PCBA in a surrounding mode by at least one turn. The antenna is wound on the PCBA, so that the length of the antenna can be increased in a limited internal space of the tire pressure sensor, and the effective space of the antenna can be particularly increased in a mode of winding the antenna on the PCBA, so that the efficiency of the antenna is higher, the signal transmitting distance of the antenna is increased, and the signal transmission stability and the interference resistance of the antenna are enhanced; therefore, the automobile receiver can stably receive the internal pressure, temperature and other information, detected by the PCBA, of the tire in real time, and real-time monitoring of the internal pressure, temperature and the like of the tire is better achieved.

    本发明提供一种胎压传感器,包括壳体,安装于所述壳体内的PCBA,安装于所述壳体内、与所述PCBA电连接的供电装置,及连接于所述PCBA上的天线;所述天线环绕在所述PCBA上,且所述天线在所述PCBA上环绕有至少一匝。通过将天线环绕于PCBA上,可以在有限的胎压传感器内部空间内,增大天线的长度,环绕在PCBA上的方式特别可以增大天线的有效空间,从而使天线的效率更高,增大天线的信号的发射距离,及增强天线的信号的传输稳定及抗干涉能力,从而可以使汽车接收器能够实时稳定地接收PCBA检测到的轮胎的内部压力、温度等信息,更好地实现对轮胎内气压、温度等的实时监控。
