Detailed Description

Referring to fig. 1 and 2, a waterproof structure is provided with a battery pack accommodating cavity, and the waterproof structure 100 is provided with a first plug structure 10 for plug-in connection with an electric host 200, a second plug structure 20 for plug-in connection with a battery pack 300, and an electrical connection module for connecting the first plug structure and the second plug structure; the waterproof structure is provided with a movable part capable of opening and closing the battery pack accommodating cavity.

When the electric host 200 is used in a wet situation, the user moves the movable portion, and referring to fig. 3 and 4, the battery pack accommodating cavity is opened, the battery pack 300 is inserted into the second insertion structure 20, and the battery pack is fixedly connected to the waterproof structure 100. The user action the movable part closes the battery package and holds the chamber, and the battery package is located the battery package and holds the intracavity, and waterproof construction plays waterproof effect to the battery package. Then, the user plugs the first plug structure 10 of the waterproof structure 100 into the plug position of the electric host 200, and the waterproof structure and the electric host are fixedly connected. The battery pack 300 supplies power to the electric motor-driven main unit 200 through the second socket structure 20, the electric connection module, and the first socket structure 10.

When the electric motor 200 is used in a dry situation, the user detaches the waterproof structure 100 from the electric motor, moves the movable portion, opens the battery pack accommodating cavity, pulls the battery pack 300 off the second inserting structure 20, and leaves the waterproof structure 100 unused. Afterwards, the user directly pegs graft the battery package on electric host computer's grafting position, and the battery package does not pass through waterproof construction and directly supplies power to electric host computer.
