[0002] The electrolyte is a medium used in batteries, electrolytic capacitors, etc. It has certain corrosiveness, provides ions for their normal operation, and ensures that the chemical reactions occurring during operation are reversible. After the battery is produced, electrolyte is injected into it. The injected electrolyte can be selected with different formulations according to requirements, but it is mainly prepared by mixing special sulfuric acid and distilled water in a certain proportion and injected into the battery interior through precise injection equipment.

[0003] However, when the electrolyte injection device for energy storage batteries injects electrolyte into the battery housing, since there will be excess air remaining in the battery housing, it will enter the interior of the battery along with the injection, making it easy to generate bubbles during injection or affecting the reaction of the electrolyte. Summary of the Utility Model

[0013] A further improvement of the technical solution of the present utility model lies in that: the bottom ends of the support legs are fixedly connected with damping shock-absorbing columns.

Specific embodiments

[0024] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The following further describes the present utility model in detail with reference to the embodiments: Embodiment 1

[0026] As Figures 1-5 shown, the present utility model provides an energy storage battery electrolyte injection device, including a battery housing 1, a placement table 6, a controller 7, and a vibration motor 18. The vibration motor 18 is fixedly connected to the bottom surface of the placement table 6, and side frames 2 are fixedly connected to the surfaces on both sides of the battery housing 1 of the placement table 6.

[0027] The top and side surfaces of the side frame 2 are respectively fixedly connected with a first clamping device 3 and a second clamping device 4 for limiting the battery housing 1. The bottom end of the power telescopic rod 12 movably penetrates through the top of the side frame 2 and is fixedly connected to the upper surface of the lower pressing plate 13.

[0028] The first clamping device 3 includes a lower pressing plate 13, a power telescopic rod 12 fixedly connected to the upper surface of the lower pressing plate 13, a rubber pad 14 fixedly connected to the bottom surface of the lower pressing plate 13, and a pressure sensor 15 fixedly connected to the center of the bottom surface of the rubber pad 14. The bottom surface of the rubber pad 14 abuts against the upper surface of the battery housing 1. During the vibration of the battery housing 1, the vibration amplitude will be reduced under the buffering effect of the deformation of the rubber pad 14 and the guide rod 16 in the first clamping device 3 and the second clamping device 4. At the same time, after increasing the output power of the vibration motor 18, the battery housing 1 can be in a high-frequency and low-amplitude vibration state, enabling the residual air inside it to be discharged more quickly and ensuring the quality of electrolyte injection. Embodiment 2

[0029] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a guide rod 16 whose bottom end movably penetrates through the top of the side frame 2 is fixedly connected to the upper surface of the lower pressing plate 13. A buffer spring 17 is sleeved on the outer wall of the guide rod 16. The bottom end of the buffer spring 17 is fixedly connected to the upper surface of the side frame 2, and the inner wall of the top end of the buffer spring 17 is fixedly connected to the top end of the guide rod 16.

[0030] The number of both the first clamping device 3 and the second clamping device 4 is two groups. The two groups of the first clamping device 3 are distributed in parallel above the battery housing 1, and the two groups of the second clamping device 4 are symmetrically distributed on both sides of the battery housing 1. During the process of the first clamping device 3 limiting and buffering the battery housing 1, the pressure sensor 15 can transmit a signal to the controller 7 according to the change of the impact pressure it receives. The controller 7 adjusts the output distance of the power telescopic rod 12 and the output power of the vibration motor 18 so as to timely adjust the amplitude and frequency of the battery housing 1 and keep its air discharge efficiency at the maximum.

[0031] The pressure sensor 15 is electrically connected to the controller 7, and support legs 8 are fixedly connected to the bottom surface of the placement table 6.

[0032] Damping shock-absorbing columns 9 are fixedly connected to the bottom ends of the support legs 8. A liquid injection hole 10 is formed in the upper surface of the battery housing 1. A docking plug 11 is inserted into the inner wall of the liquid injection hole 10, and a liquid injection pipe 5 is inserted into the inner wall of the docking plug 11.

[0033] Next, the working principle of this energy storage battery electrolyte injection device will be specifically described.

[0034] As Figures 1-5As shown, during use, the power telescopic rod 12 is activated to push the lower pressing plate 13. The lower pressing plate 13 then drives the rubber pad 14 and the pressure sensor 15 to move downward to overlap with the surface of the battery case 1. At the same time, the second clamping device 4 is synchronously activated. When the pressure value detected by the pressure sensor 15 reaches the rated range, it stops. Subsequently, the docking plug 11 is docked with the liquid injection hole 10, and then electrolyte is injected into the battery case 1 through the liquid injection pipe 5. At the same time, the vibration motor 18 is activated to transmit vibration to the battery case 1 through the placement table 6. At this time, the battery case 1 starts to vibrate. During the vibration of the battery case 1, the remaining air inside it will float in the electrolyte and be discharged through other liquid injection holes 10, thereby avoiding problems such as the easy generation of bubbles during injection or affecting the reaction of the electrolyte during use.

[0035] As the amount of electrolyte injected into the battery case 1 increases, the output power of the vibration motor 18 and the output length of the power telescopic rod 12 can be increased as needed, thereby being able to reduce the relative amplitude of the battery case 1.

[0036] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. Without more limitations, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element. The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements without departing from the spirit of the present utility model are within the protection scope of the present utility model.
