[0013] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0014] When installing the longitudinal acceleration sensor, first separate the cover plate from the housing, then install the PCB board with the longitudinal acceleration sensor components inside the housing. After the installation is completed, close the cover plate onto the housing and seal it. Finally, insert the housing into the automobile sheet metal bracket to complete the installation. The plug-in installation method does not require bolts for fixing, and the operation is simple, which solves the problem of inconvenient disassembly and installation of the longitudinal acceleration sensor.
