Vehicle engine sealing structure testing device

The invention belongs to the technical field of vehicle detection equipment, and particularly relates to a vehicle engine sealing structure testing device. The device comprises a base, and an engine placing frame and a sealing test assembly are installed on the base. The engine placing frame comprises supporting legs and a bottom leakage detection unit installed on the supporting legs. The bottomleakage detection unit comprises a shell, a controller, a buzzer and a display, a deformable telescopic strip layer, an adsorption layer, a waterproof and oilproof layer and a deformation layer are sequentially arranged in the shell from top to bottom, and a humidity sensor is arranged in the telescopic strip layer; and the sealing test assembly comprises a front leakage detection unit, a top leakage detection unit, a left side leakage detection unit, a right side leakage detection unit, a rear leakage detection unit and a displacement assembly used for controlling displacement of the five units. The six leakage detec
