[0028] Preferably, a protective cover 103 is further provided below the base 100. The protective cover 103 covers the box body 101 inside. An air inlet through hole 1032 and an air outlet through hole 1033 are respectively provided on the front side wall and the rear side wall of the protective cover 103. Since the high thermal conductivity heat dissipation fins 1011 are generally made of aluminum sheets, when they are exposed, they are not only easily bumped and deformed, but also easily cut the user. By providing the protective cover 103 to cover them inside, a dual protection effect can be achieved.

[0032] Preferably, an embedding groove is provided on each of the front and rear sides of the top of the base 100. The embedding groove is an S-shaped structure, and a rubber sleeve is provided in the embedding groove. A set of power lines is respectively passed through the two rubber sleeves. By providing the S-shaped embedding groove and burying the power lines in cooperation with the rubber sleeve, the sealing position can be increased. Even if the rubber sleeve ages locally, it can still play a sealing role, and the water leakage problem caused by wire threading can be effectively avoided.

[0033] Preferably, a rear wheel assembly 30 is provided on the base 100. The rear wheel assembly 30 has a hub motor. One end of a set of power lines is connected to the controller, and the other end is connected to the hub motor.
