Description

Technical Field

[0001] The present invention relates to a mobile power tool, and particularly to a waterproof design of a battery pack. Background Art

[0002] A battery pack is applied to an electric main body to make the electric main body convenient to move. Different types of electric main bodies have different application scenarios, and there are different requirements for whether the battery pack needs to be waterproof or the waterproof requirement level. For example, when the electric main body is a drill and is in a dry application scenario, it does not need to be waterproof; when it may be in a wet application scenario, it needs to be waterproof. Another example is that when the electric main body is a hand-held washing machine, a certain level of waterproof requirement is needed when high-pressure flushing the product to be cleaned; when used for plant watering, it does not need to be waterproof. For a specific electric main body, a fixed battery pack waterproof structure is equipped. When used in a non-waterproof scenario, the battery pack waterproof structure becomes a burden and is not conducive to the heat dissipation of the battery pack. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a waterproof structure that can be easily disassembled and assembled with the electric main body and can also be easily disassembled and assembled with the battery pack.

[0004] To solve the above technical problem, the present invention provides the following technical solution: a waterproof structure is provided with a battery pack accommodation cavity, and the waterproof structure is provided with a first plug-in structure for plugging into the electric main body, a second plug-in structure for plugging into the battery pack, and an electrical connection module connecting the first plug-in structure and the second plug-in structure; the waterproof structure is provided with a movable part capable of opening and closing the battery pack accommodation cavity.

[0005] When the battery pack needs to be waterproofed, the battery pack enters the battery pack accommodation cavity through the movable part and is plugged into the second plug-in structure, and the waterproof structure is plugged onto the electric main body through the first plug-in structure.

[0006] When the battery pack does not need to be waterproofed, the battery pack is detached from the second plug-in structure, taken out of the battery pack accommodation cavity through the movable part, the first plug-in structure of the waterproof structure is detached from the electric main body, the waterproof structure is left idle, and the battery pack is plugged into the electric main body.

[0007] The waterproof structure of the present invention can play a waterproof role for the battery pack when the electric main body is used in a wet scenario; when the electric main body is used in a dry scenario, it can be detached from the electric main body, so that the battery pack is directly plugged into the electric main body, avoiding becoming a burden in the use of the electric main body, and being beneficial to the heat dissipation of the battery pack and the light weight of the electric main body.

[0018] Combined with Figure 1 and Figure 2 , a waterproof structure is provided with a battery pack accommodation cavity. The waterproof structure 100 is provided with a first plug-in structure 10 inserted into the electric main engine 200, a second plug-in structure 20 inserted into the battery pack 300, and an electrical connection module connecting the first plug-in structure and the second plug-in structure; the waterproof structure is provided with a movable part capable of opening and closing the battery pack accommodation cavity.

[0019] When the electric main engine 200 is applied in a humid environment, the user operates the movable part, referring to Figure 3 and Figure 4 , to open the battery pack accommodation cavity, insert the battery pack 300 into the second plug-in structure 20, and the battery pack is fixedly connected to the waterproof structure 100. The user operates the movable part to close the battery pack accommodation cavity. The battery pack is located in the battery pack accommodation cavity, and the waterproof structure plays a waterproof role for the battery pack. Then, the user inserts the first plug-in structure 10 of the waterproof structure 100 into the plug-in position of the electric main engine 200, and the waterproof structure is fixedly connected to the electric main engine. The battery pack 300 supplies power to the electric main engine 200 through the second plug-in structure 20, the electrical connection module, and the first plug-in structure 10.

[0020] The electric main engine 200 is applied to a drying scenario. The user removes the waterproof structure 100 from the electric main engine, operates the movable part to open the battery accommodation cavity, pulls out the battery pack 300 from the second plugging structure 20, and leaves the waterproof structure 100 idle. Then, the user directly plugs the battery pack into the plugging position of the electric main engine, and the battery pack directly supplies power to the electric main engine without passing through the waterproof structure.

[0021] As an option, when the waterproof structure 100 is not in use, the battery pack 300 can be directly plugged into the electric main engine 200 without a converter. Alternatively, the battery pack 300 is plugged into the electric main engine 200 through a converter. The converter is provided with a first type of plug interface plugged into the plugging position of the electric main engine, and a second type of plug interface plugged into the battery pack. The converter is applicable to the situation where the battery pack 300 cannot be directly plugged into the electric main engine 200.

[0022] As an option, the battery pack 300 with different plug connectors or plug interfaces is plugged into the second plugging structure 20 through a converter, making the waterproof structure 100 of the present invention applicable to different models of battery packs.

[0023] The waterproof structure 100 includes a waterproof housing 30 and a waterproof cover 40. The first plugging structure 10, the second plugging structure 20, and the electrical connection module are arranged on the waterproof cover, and the waterproof housing is movably connected to the waterproof cover.

[0024] Combined Figure 1 、 Figure 2 The first plugging structure 10 is provided with a button 11. One end of the button is provided with a buckle structure 110. When the first plugging structure is plugged into the plugging position of the electric main engine, the plugging position of the electric main engine is engaged with the buckle structure 110 to lock the connection between the waterproof cover 40 and the electric main engine. Press the button 11, and the buckle unlocks the connection between the waterproof cover and the electric main engine, and the user can remove the first plugging structure from the electric main engine.

[0025] The second plugging structure 20 is arranged on the conversion bracket 60, and the conversion bracket is installed on the waterproof cover 40 through a threaded connector.

[0026] The electrical connection module includes a pin base 51 matching the first plugging structure 10, a PCB board 52 connected to the pin base, a socket 53 matching the second plugging structure 20, and a wire connecting the PCB board and the socket.

[0027] One side of the waterproof housing 30 is hinged to one side of the waterproof cover 40, and a locking device 31 is provided on the other side of the waterproof housing and the other side of the waterproof cover. The waterproof cover 40 is plugged into the electric main unit 200. The waterproof housing 30 constitutes a movable part for opening and closing the battery accommodation cavity. When the user opens the locking device, the waterproof housing rotates relative to the waterproof cover, and the battery pack in the waterproof structure 100 is exposed. When the user closes the locking device, the waterproof housing is locked on the waterproof cover, and the battery accommodation cavity is sealed.

[0028] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
