The invention relates to the field of sensors, and provides an automobile tire pressure sensor which comprises a chuck body, an air hole core, a sensor body, a connecting pipe, a connecting cover and a protection mechanism, a connecting hole is formed in the chuck body, the air hole core is installed on the inner wall of the connecting hole, the connecting cover is installed on the air hole core, and the connecting pipe is installed on the connecting cover; the sensor body is fixedly connected to one end of the connecting pipe, and the protection mechanism is connected to the chuck body. The sensor body can be effectively protected through the anti-collision plate, the sensor body is prevented from being damaged by foreign objects, the anti-collision plate can be doubly buffered through the third elastic piece and the first hollow balloon, external force is effectively buffered, whether the external force is larger than a preset value or not can be automatically detected through the pricking needle, and the safety is improved. And the first rigid cover and the second rigid cover are automatically closed when the value is greater than the preset value, so that the sensor body is protected in a closed manner, and the protection effect is enhanced.

    本发明涉及传感器领域,提供了一种汽车轮胎压力传感器,包括卡盘本体、气孔芯、传感器本体、连接管、连接盖以及保护机构,卡盘本体上开设有连接孔,气孔芯安装于连接孔内壁,连接盖安装于气孔芯上,连接管安装于连接盖上,传感器本体固接于连接管一端,保护机构连接于卡盘本体上。本发明通过防撞板能够使传感器本体进行有效的防护,防止外物损坏传感器本体,通过第三弹性件和第一空心球囊能够对防撞板进行双重缓冲,有效缓冲外力,通过刺针能够自动检测外力是否大于预设值,并在大于预设值时自动使第一刚性盖和第二刚性盖合上,对传感器本体进行封闭式防护,加强防护效果。
