[0026] In the present invention, the fixed upper cover 2 is welded to the upper end of the electric drive module protective shell 1 , and the size of the fixed upper cover 2 is adapted to the size of the electric drive module protective shell 1 .

[0029] Specifically, the design of the heat dissipation hole 6 effectively solves the problem of heat generated by the electric drive module during operation.
