Problems solved by technology
[0002] In the automatic production of hard-shell batteries, after the battery packs the cells and the cover plate, the electrolyte needs to be automatically poured through the liquid injection hole on the cover plate. After the liquid injection is completed, it is sealed. However, the traditional liquid injection hole has a single structure. It is impossible to adjust the liquid inlet flow rate of the liquid injection hole, resulting in the electrolyte overflowing the liquid injection hole when the interior is almost full in the later stage, making it difficult to clean the outer wall of the upper cover plate. The introduction and defects of the existing technology, for this reason we propose a Large-capacity automotive battery case upper cover liquid injection hole expansion mechanism is used to solve the above problems

The invention discloses an expansion mechanism for a liquid injection hole in an upper cover of a large-capacity automobile battery shell. The inside of the plate is connected with a liquid injection hole, a liquid outlet is opened in the middle of the bottom of the liquid injection hole, and baffle plates are fixed on the bottom surfaces of both ends of the liquid injection hole. The baffle plate and the inner wall of the liquid injection hole form a cavity, and the cavity is An elastic piece is fixed in the middle of the bottom surface, the free end of the elastic piece is fixedly connected with the bottom surface of the connecting rod, the top end of the connecting rod is fixedly connected with the bottom surfaces of both ends of the horizontal plate, and a top rod is fixed in the middle of the bottom surface of the horizontal board. The end is fixedly connected at the middle position of the top of the sealing ball, and the sealing ball is movably clamped in the liquid outlet. This device can quickly adjust the size of the liquid outlet, and the operation is simple and effective.
Description
technical field [0001] The invention relates to the technical field of storage batteries, in particular to an expansion mechanism for a liquid injection hole in an upper cover of a large-capacity automobile storage battery shell. Background technique [0002] In the automatic production of hard-shell batteries, after the battery packs the cells and the cover plate, the electrolyte needs to be automatically injected through the injection hole on the cover plate. After the injection is completed, it is sealed. However, the traditional injection hole has a single structure. The flow rate of the liquid injection hole cannot be adjusted, resulting in the electrolyte overflowing the liquid injection hole when the interior is filled quickly in the later stage, making it difficult to clean the outer wall of the upper cover plate. The existing technology is introduced and defects. For this reason, we propose a The liquid injection hole expansion mechanism of the upper cover of the la...
