[0032] The bottom of the front head base 41 is provided with an arc-shaped guide surface, which serves as a guide for the roller shutter to rotate into the water tank structure 5. The bottom of the arc-shaped guide surface is covered with a suitable waterproof cotton to prevent water from entering the vehicle from the side of the arc-shaped guide surface. The waterproof cotton 42 at the front head is in contact with the surface of the guide rail 21 to form a seal, preventing water from flowing into the interior of the front head base 41 from the surface of the guide rail 21, thus forming a waterproof step.

[0033] The installation of the front waterproof rubber pad frame 44 is a unique step in this embodiment. It serves as a vertical reinforcement and fastening mechanism to prevent the front head structure 4 from detaching from the guide rail 21 when it impacts the roller shutter during the stretching process, and also serves as an anti-theft measure.

[0034] Furthermore, the water tank structure 5 includes a water tank body 51, a water tank outlet 52, a turntable 53, a sealing plate 54, and a cover plate 55.
