Waterproof charging connection device

Abstract

This invention relates to a waterproof charging connection device, comprising: a housing, a power supply unit, a cover, two caps, and two reset elements. The housing has an opening along the front-to-back direction. The power supply unit is located inside the housing and corresponds to the opening. The cover is connected to the housing and has two connecting parts inside. The two connecting parts are arranged sequentially along the front-to-back direction and are located on opposite sides of the cover opening, forming an asymmetrical configuration. Furthermore, each cap is pivotally connected to one of the connecting parts, allowing the caps to pivot inside the cover. Each reset element is located between the caps and the cover, and in conjunction with the asymmetrical configuration, ensures that a portion of each cap overlaps along the front-to-back direction when covering the cover opening. This prevents the caps from colliding and jamming, thereby extending the service life of the waterproof charging connection device.

Claims

1. A waterproof charging connection device, comprising: a housing having an installation space formed therein, and a housing opening communicating with the installation space through a front-rear direction; a power supply unit located inside the installation space, having a circuit board and a socket, the circuit board being electrically connected to the socket, and the socket being positioned corresponding to the housing opening; and a cover connected to the housing, having a cover space located inside the cover and a cover opening communicating with the cover space, the cover space having two connecting portions adjacent to the cover opening, the two connecting portions being arranged sequentially front-rear along the front-rear direction and respectively located on opposite sides of the cover opening to form an asymmetrical configuration; Two covers, located inside the aforementioned cover space, each of the covers being pivotally connected to one of the aforementioned connecting portions, allowing each of the covers to swing within the aforementioned cover space. This allows the two covers to transition from an open state away from the cover opening to a covered state that jointly covers the cover opening. When the two covers are in the covered state, a portion of the two covers overlaps along the aforementioned front-back direction. Two reset elements, each disposed between one of the covers and the cover, are configured in asymmetrical way to ensure that a portion of the two covers overlaps along the aforementioned front-back direction when the two covers transition from the open state to the covered state.

2. The waterproof charging connection device as described in claim 1, wherein, The aforementioned cover has two pivot rod portions and a covering portion located between the two pivot rod portions. One of the covering portions of the aforementioned cover has a shielding section and a rib section. The shielding section is adjacent to the covering portion of the other aforementioned cover, and the rib section is located behind the covering portion of the other aforementioned cover.

3. The waterproof charging connection device as described in claim 2, wherein, The connecting portion has two connecting grooves into which the pivot rod portion is inserted. The connecting groove is provided with a receiving wall and two limiting walls. The receiving wall surrounds and forms a receiving space for receiving the pivot rod portion. The two limiting walls are located at opposite ends of the receiving wall. The two limiting walls are spaced apart from each other to form a limiting space with a profile smaller than the pivot rod portion, so that the two limiting walls can restrict the pivot rod portion within the receiving space.

4. The waterproof charging connection device as described in claim 3, wherein, The aforementioned cover has two protruding ribs located in the space of the aforementioned cover. The two protruding ribs are located on opposite sides of the opening of the aforementioned cover. One of the connecting grooves of the aforementioned connecting part is formed on one of the aforementioned protruding ribs, and the other connecting groove of the aforementioned connecting part is formed on the other of the aforementioned protruding ribs.

5. The waterproof charging connection device as described in claim 1, wherein, The aforementioned cover extends from the opening of the cover to form an annular rib located inside the space of the cover. The end face of the annular rib is provided with two contact surfaces and two turning surfaces. The two contact surfaces respectively contact one of the aforementioned covers, and the two turning surfaces are located between the two contact surfaces, so that the two contact surfaces can be spaced apart from each other and present a non-coplanar state.

6. The waterproof charging connection device as described in claim 5, wherein, Each of the aforementioned covers is provided with a covering surface for covering the opening of the cover. When the two aforementioned covers are in the aforementioned covering state, the two aforementioned covering surfaces will be offset from each other along the aforementioned front-back direction and will respectively contact one of the aforementioned contact surfaces.

7. The waterproof charging connection device as described in claim 1, wherein, The aforementioned cover has a ring portion and a stop portion, which together form the cover space. The ring portion is connected to the housing, and the cover opening is formed at the stop portion. The two connecting portions are respectively separated from the stop portion by different distances.

8. The waterproof charging connection device as described in claim 1, wherein, The aforementioned cover forms a drainage opening, which is connected to the space of the aforementioned cover. The normal direction of the drainage opening and the normal direction of the opening of the aforementioned shell form an angle.

9. The waterproof charging connection device as described in claim 1, wherein, When the two covers are in the opened state, the two reset elements can generate reset forces of different magnitudes through the asymmetrical configuration, so that the two covers can sequentially cover the opening of the cover through the reset forces of different magnitudes.
