Power battery injection molding top cover structure and power battery

The utility model relates to the technical field of batteries, in particular to a power battery injection molding top cover structure and a power battery. The power battery injection molding top cover structure comprises a pole; a receding hole suitable for the pole to pass through is formed in the light aluminum sheet in a penetrating manner; and the injection molding body comprises a main body part which is arranged relatively below the bright aluminum sheet and an isolation skirt edge which is suitable for separating and fixing the pole and the bright aluminum sheet. According to the power battery injection molding top cover structure provided by the utility model, the pole and the smooth aluminum sheet are separated through the isolation skirt arranged on the injection molding body, and meanwhile, the pole and the smooth aluminum sheet are connected into a whole by virtue of the isolation skirt, so that an insulation effect can be achieved while the pole and the smooth aluminum sheet are fixed; and only t
