Obviously, the described embodiments are some embodiments but not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0020] The embodiment of the present application provides a high specific energy battery liquid injection device with fast liquid injection and no residue, which comprises a battery box 1. Figures 1-3 As shown in the figure.

[0021] The upper surface of the battery box 1 is provided with an opening 2, the opening 2 is matched with a liquid injection piece 3, the liquid injection piece 3 comprises a liquid injection bag 31, the side surface of the liquid injection bag 31 is matched with a first throttling ball 32 and a second throttling ball 34, the first throttling ball 32 and the second throttling ball 34 are fixedly connected with a curved panel 33, the surface of the curved panel 33 is rotatably sleeved with an adaptive rod 35, the end surface of the adaptive rod 35 is sleeved with a fit sleeve 37, the outer surface of the fit sleeve 37 is fixedly connected with a dial ring tooth 38, the teeth of the dial ring tooth 38 are movably connected with an inner ring seat 4, and the top of the liquid injection bag 31 is fixedly provided with a sealing column 6.

[0022] The outer surface of the inner ring seat 4 is fixedly connected with a vertical block 5, and the outer surface of the adaptive rod 35 is sleeved with a right-angle stable seat 36, and the side surface of the right-angle stable seat 36 is adaptively installed with the inner ring seat 4.

[0023] The liquid injection bag 31 is composed of a multi-cone combination, and the liquid injection bag 31 is integrally made of corrosion-resistant material.

[0024] Specifically, by opening the opening 2 on the surface of the battery box 1, the electrolyte liquid can be added in time, and the injection bag 31 cooperates with the first throttle ball 32 and the second throttle ball 34. When the electrolyte liquid flows into the injection bag 31 quickly, it will cause the expansion of the injection bag 31, and then the first throttle ball 32 supports the top of the injection bag 31, and the second throttle ball 34 limits the flow at the bottom of the injection bag 31, which indirectly speeds up the falling rate of the electrolyte liquid, reduces the residual condition of the inner wall, and the fixed connection of the curved panel 33 can ensure the position of the first throttle ball 32 and the second throttle ball 34, which helps the electrolyte liquid to be added faster, effectively improves the injection efficiency of the battery box 1, and then the rotating speed of the adapter rod 35 is more balanced through the movable clamping of the ring tooth 38 and the inner ring seat 4, which indirectly ensures the stable addition of the electrolyte liquid in the inner wall of the injection bag 31, and the sealing column 6 is arranged at the top of the injection bag 31, which reduces the splashing and spilling of the electrolyte liquid when injected.

[0025] The spherical diameters of the first throttle ball 32 and the second throttle ball 34 are the same; for example, as shown in Figures 2-3 .

[0026] The contact positions of the first throttle ball 32 and the second throttle ball 34 in the injection bag 31 are the head and tail.

[0027] The top of the sealing column 6 is provided with a panel 7, the upper surface of the panel 7 is embeddedly connected with a disc 8, the top of the disc 8 is fixedly connected with a pump 9, the side surface of the pump 9 is communicated with a liquid delivery hose 10, and the bottom end of the liquid delivery hose 10 is communicated and installed with the sealing column 6.

[0028] The surface of the disc 8 is provided with a straight shaft 11, and the top of the straight shaft 11 is adaptively installed with a motor 12.

[0029] Specifically, through the embedded connection of the panel 7 and the disc 8, the pump 9 can avoid shaking when pumping the electrolyte liquid, and the setting of the liquid delivery hose 10 can allow the electrolyte liquid to be transported for a long time. Finally, through the adaptive installation of the motor 12 and the straight shaft 11, the electrolyte liquid is pushed by centrifugal force before being injected, which reduces the intermediate blockage.

[0030] The number of the first throttle ball 32, the curved panel 33 and the second throttle ball 34 is two groups; for example, as shown in Figures 3-4 .

[0031] The distribution mode of the two groups of the first throttle ball 32, the curved panel 33 and the second throttle ball 34 is symmetrical arrangement.

[0032] The side surface of the motor 12 is provided with a connecting block 13, and the end surface of the connecting block 13 is drivingly matched with a lead screw transmission part 14.

[0033] Specifically, through the transmission cooperation of the screw rod transmission member 14 and the connecting block 13, the vertical distance between the liquid injection bag 31 and the opening 2 is reduced, and the electrolyte liquid can be directly added, reducing the dripping and spilling situation.

[0034] Working principle: first start the screw rod transmission member 14, the screw rod transmission member 14 drives the connecting block 13 to displace synchronously, then turn on the motor 12, the motor 12 drives the straight shaft 11 and the disc 8 to rotate, and the excess air in the liquid injection bag 31 is discharged to avoid the overflow of the electrolyte liquid, and at the same time, the pump liquid machine 9 is started, the electrolyte liquid is transmitted through the infusion hose 10, and reaches the inside of the liquid injection bag 31;

[0035] After that, the liquid injection bag 31 injects the electrolyte liquid side expansion stress, the first throttle ball 32 is affected, and the upper side of the liquid injection bag 31 is supported, then the rotation of the curved panel 33 is transmitted, so that the second throttle ball 34 extrudes the lower side of the liquid injection bag 31, so that the top of the liquid injection bag 31 can be stably injected, the bottom is limited, the flow rate of the electrolyte liquid in the liquid injection bag 31 is relatively increased, and at the same time, the rotation speed of the curved panel 33 is adjusted by the ring gear 38, and finally the electrolyte liquid is quickly injected into the battery box 1.
