Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

The three covers are connected through the pivot 21 of the two connecting components 2 arranged on the two sides along the left-right direction, which passes through the corresponding connecting through-holes. The rotation of the pivot 21 can drive the initiative cover 13 and the driven cover 12 to move between the unfolded position and the storage position. Specifically, when the initiative cover 13 and the driven cover 12 are located in the unfolded position, the initiative cover 13 and the driven cover 12 both protrude from the second side 114 of the fixed cover 11, so as to increase the shielding range and improve the shielding effect, thereby preventing water from splashing onto the high-voltage wire harness and the interface. When the initiative cover 13 and the driven cover 12 are located in the storage position, more space is left for the maintenance of the equipment by the staff. In summary, the waterproof cover of the utility model does not need to change the vehicle wiring.

[0037] Further, since the driving cover 13 should be able to drive the driven cover 12 to rotate, the size and curvature of the outer wall of the driving cover plate 131 and the inner wall of the driven cover plate 121 are close to each other, further, by adjusting the shape and curvature of the corresponding positions of the two, the driving cover 13 can prevent the driven cover 12 from being separated when driving the driven cover 12.
