[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figs. 1 to 4 As shown, a lithium-ion electrolyte dripping device is disclosed. This device replaces the traditional manual addition of electrolyte to batteries, reducing leakage and potential harm to the human body caused by manual addition. The device includes a dripping control platform 1 mounted on a control frame. A container 2 for holding the electrolyte is mounted on the dripping control platform 1. The bottom of the container 2 has a channel for the electrolyte to pass through, and the channel is connected to a flexible pipe that extends into the battery to which electrolyte needs to be added. A piston, which slides and adapts to the inner wall of the container 1, is installed inside the container 1. The other end of the piston is connected to a mechanism that drives the piston to move, squeezing the electrolyte from the container 2 through the channel and into the battery (container) to which electrolyte needs to be added. By controlling this mechanism, the piston is moved, squeezing the electrolyte from the container 2 through the channel and then through the pipe connected to the channel into the battery (container) to which electrolyte needs to be added.

[0023] In this embodiment, the active mechanism includes an electric push rod 3. The housing of the electric push rod 3 is mounted on a fixed plate 4. The output end of the electric push rod 3 is connected to a push plate, and a piston is mounted on the push plate. By extending and retracting the electric push rod 3, the piston is driven to slide along the inner wall of the container in a sealed manner. When electrolyte needs to be added to the battery or container, the electric push rod 3 is controlled to drive the piston to "extract" along the inner wall of the container 2. The electrolyte in the container 2 is forced through the "extraction force" from the channel at the bottom of the container 2 into the flexible pipe at the end of the channel. Since a control valve is installed on the flexible pipe, the speed and flow rate of electrolyte flow can be easily controlled. Furthermore, the flexible pipe is made of existing high-strength, flexible, and stretchable materials, which can avoid the weight of the flexible pipe and the adaptable stretching length during use. This facilitates the insertion of the other end of the flexible pipe into the battery or container and reduces the risk of breakage and electrolyte leakage.

[0024] Example 2

[0025] Based on Embodiment 1, movable guide rods 41 are respectively provided on both sides of the output end of the electric push rod 3; one end of each movable guide rod 3 is connected to the push plate, and the other end of each movable guide rod 41 passes through the fixed plate 4 and is hinged to the connecting block via a hinge seat. The connecting block is connected to the fixed plate 4 via a connecting rod. When the electric push rod 3 drives the piston to move and translate, the two movable guide rods 41 can play a guiding role, so that the piston can make a tight contact with the inner wall of the container 2 while sliding stably along the inner wall of the container 2, realizing the "piston function", squeezing the electrolyte contained in the container 2 from the channel opening into the battery or container at the other end of the flexible pipe.

[0026] Meanwhile, a movable adjusting plate 5 is mounted and connected to one side of the fixed plate 4. A support plate is connected to the bottom of the movable adjusting plate 5, and the container 2 is bolted to the support plate. The fixed plate 4 is slidably connected to the movable adjusting plate 5 via a sliding guide rail. Furthermore, a cylinder 6 is connected to the fixed plate 4 to drive it to slide along the movable adjusting plate 5 via the sliding guide rail. The cylinder body of the cylinder 6 is bolted to the movable adjusting plate 5. The bottom of the movable adjusting plate 5 is rotatably connected to the top surface of the dripping control platform 1 via a rotating shaft. One end of the movable adjusting plate 5 near the dripping control platform is hinged to one end of a lifting cylinder 7, and the other end of the lifting cylinder 7 is hinged to the movable adjusting plate 5. If the electrolyte level in container 2 is insufficient, and the piston can no longer squeeze out the electrolyte at that position, the lifting cylinder 7 is controlled to rotate the movable adjusting plate 5 along the top surface of the dripping control platform 1 to a certain position, so that container 2 is as vertical as possible and the opening of container 2 is as low as possible. This facilitates the extraction of electrolyte from container 2 through the piston into the battery or container. At the same time, the cylinder 6 is controlled to move the fixed plate 4 along the movable adjusting plate 5, ultimately allowing the piston to be positioned as close as possible to the bottom of the inner wall of container 2, squeezing the electrolyte from container 2 into the battery or container as completely as possible. This ensures that the electrolyte in container 2 is of a uniform type when it is added again, avoiding mixing due to residual electrolyte in container 2 or waste during cleaning of container 2.

[0027] Finally, the dripping device uses a movable mechanism to drive a piston installed in the container, squeezing the electrolyte in the container through the channel and into the battery (container) that needs electrolyte. This avoids leakage caused by manual addition of electrolyte, thus preventing the electrolyte from harming the human body.
