The invention discloses a vacuum booster. A vacuum booster shell is provided with a vacuum pressure sensor. The vacuum pressure sensor comprises a vacuum pressure sensor inner shell which is fixedly connected to the inner surface of the vacuum booster shell and communicates with the interior of the vacuum booster, a vacuum pressure sensor outer shell fixedly connected to the outer surface of the vacuum booster shell and communicating with the external environment, a vacuum pressure sensor chip arranged on a control circuit board fixed in the vacuum pressure sensor inner shell, and a hollowed-out antenna with one end connected with the control circuit board and the other end opened and penetrating through the vacuum booster shell to enter the vacuum pressure sensor outer shell. The vacuum booster can send internal and external pressure difference signals outwards in a wireless transmission mode, and the problems that wiring is difficult when an engine cabin is arranged, and a boosting system fails due to the fact that a cable and a connector lug are prone to aging and failing are solved.

    本发明公开了一种真空助力器,真空助力器壳体上设有真空压力传感器,真空压力传感器包括:真空压力传感器内壳体,固定连接至真空助力器壳体的内表面并与真空助力器的内部连通;真空压力传感器外壳体,固定连接至真空助力器壳体的外表面并与外部环境连通;真空压力传感器芯片,设置在控制电路板上,控制电路板固定在真空压力传感器内壳体之内;内部镂空的天线,一端连接控制电路板,另一端开口并穿过真空助力器壳体进入真空压力传感器外壳体;上述真空助力器可将内外压力差值信号以无线传输的方式向外发送,克服了发动机机舱布置发动机机舱布置布线困难,线缆与接线头容易老化失效导致助力系统失效的问题。
