The invention relates to a printed circuit board mounting structure, an assembling method, a motor controller and a vehicle. The printed circuit board mounting structure comprises a printed circuit board and an insulated gate bipolar transistor, the printed circuit board is provided with a current sensor fixing column and a bolt mounting hole, the shortest distance between the current sensor fixing column and the bolt mounting hole is 4.3 mm, and the bolt mounting hole is filled with adhesive. The invention further provides an assembly method of the printed circuit board installation structure. The assembly method comprises the steps that the insulated gate bipolar transistor is installed on the end cover shell through the fixing glue; a printed circuit board is assembled on an end cover shell through a connecting piece, and meanwhile, a bolt mounting hole in the printed circuit board is filled with bonding glue. The invention further provides a motor controller which comprises the printed circuit board mounting structure. The invention further provides a vehicle which comprises the motor controller. On the premise that the overall layout of the motor controller is not changed, the problem of installation stress is solved, and the structural vibration performance is improved.
