How to include images into exe generated by PyInstaller in Python

Question

I use PyQt5 to develop a GUI application in python, and that works. Now, I would like to generate exe file using PyInstaller, but I don't know how to include image files into exe file. I mean I wish the exe file doesn't rely on external image files any more. I have tried the method below, but it seems doesn't work for me. Pyinstaller and --onefile: How to include an image in the exe file

following is part of my code:

my code:

class DASH(QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.animation = Animation()
        self.setCentralWidget(self.animation)
        exitAct = QAction(QIcon(r'car.png'), 'Exit', self)
        exitAct.setShortcut('Ctrl+Q')
        exitAct.setStatusTip('Exit application')
        exitAct.triggered.connect(self.close)
