The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order to facilitate understanding of the technical scheme of the present utility model, first, the technical problem to be solved by the present application will be described.
Referring to fig. 1, fig. 1 shows a schematic view of a battery top cover seal and fitting combination. As shown in fig. 1, the device comprises a top cover plate 01, an upper plastic part 02, a lower plastic part 03, a sealing ring 04 and an electrode column 05. The sealing ring 04 is extruded and deformed after the electrode column 05 and the top cover plate are subjected to certain pressure, and then is tightly attached to the top cover sheet 01 and the electrode column 05, so that the sealing effect is achieved. However, since the upper plastic part 02 and the lower plastic part 03 have a certain sealing effect, when the sealing parts are not sealed in place or compressed in place, the existence of the upper plastic part 02 and the lower plastic part 03 can also play a certain sealing effect to a certain extent, so that in the process of product testing, as shown in fig. 1, the practical helium gas cannot flow from the line shown in fig. 1, and the sealing test misjudgment is that the sealing effect is achieved, so that whether the sealing part really plays a role in sealing cannot be accurately measured.
Based on the technical problems, the utility model provides a device for improving the sealing performance of a top cover of a new energy battery, which is used for solving the problem that whether a sealing element truly plays a sealing effect or not cannot be accurately measured, and the quality of a product is judged to be qualified by mistake.
As shown in fig. 1, the device for improving the sealing performance of the top cover of the new energy battery is characterized by comprising a top cover plate 10, an electrode column 20, a plastic part and a sealing ring 40.
Wherein, be equipped with the through-hole on the lamina tecti 10, electrode post 20 includes fixing base 22 and the installation end 21 and the lower surface of lamina tecti 10 are supported in the through-hole to installation end 21 that are connected with fixing base 22, and the plastic part setting is equipped with air groove 321 on the periphery of electrode post 20 for fixed electrode post 20, air groove 321 is used for permeating lamina tecti 10 upper surface and lower surface air. The sealing ring 40 is sleeved on the outer periphery of the mounting end 21 of the electrode column 20 and is positioned between the electrode column 20 and the side wall of the through hole, and is used for sealing a gap between the top cover plate 10 and the electrode column 20.
That is, by adding the gas passing groove 321 to the plastic member, the sealing ring 40 may be sealed loose when the top cover plate 10 and the electrode column 20 are not compressed precisely enough, and at this time, due to the existence of the gas passing groove 321, the helium gas which can be detected during the detection flows through the gas passing groove 321 and the gap where the sealing is not finished, so that the sealing loose of the sealing ring 40 can be detected.
Referring to fig. 3, when the sealing performance is detected, the device 100 for improving the sealing performance of the top cover of the new energy battery is placed in the testing device, helium gas is sprayed from one side of the fixing seat of the electrode column, and vacuum is drawn from the other end of the electrode column, so that whether the sealing is poor or not is detected.
As shown in fig. 1, in one embodiment of the present utility model, the plastic parts include an upper plastic part 31 and a lower plastic part 32, wherein a part of the upper plastic part 31 is disposed at the upper half portion of the through hole, the other part extends to the end of the mounting end 21 and the upper surface of the top cover 10, a first end of the lower plastic part 32 is disposed in the gap between the top cover 10 and the fixing base 22, and a second end extends along the lower surface of the top cover 10 and the outer periphery of the fixing base 22.

The structure can play a better sealing effect.
In one embodiment of the present utility model, the air passing groove 321 is disposed parallel to the upper surface of the fixing base 22, and a space is formed between the bottom of the air passing groove 321 and the upper surface of the fixing base 22. Thus, when the electrode column 20 and the top cover plate 10 are not tightly compressed, gas can flow through the gas passing groove 321, which is beneficial to the accuracy of detection.
In one embodiment of the present utility model, a circle of grooves 211 is formed on the outer circumference of the mounting end 21 of the electrode post 20, and a protrusion 311 matching with the grooves 211 is formed on one side of the upper plastic member 31 near the mounting end 21. This structure can improve the connection firmness of the electrode column 20 and the seal ring 40.
