Description

Power battery protection film for new energy automobile Technical Field The utility model relates to the field of power battery protection films, in particular to a power battery protection film for a new energy automobile. Background The power battery protection film is used as an important component of a power battery system of a new energy automobile, is mainly used for protecting the surface of the battery from being damaged by scraping, corrosion and other external factors, ensures the safety and stability of the battery, prolongs the service life of the battery, and has non-negligible influence on the overall performance and market competitiveness of the new energy automobile when the power battery protection film is used for rapidly developing in the new energy automobile industry; at present, in the in-service use process of a power battery protection film, a roller is generally inserted into a driving roller on a machine table, when film releasing operation is carried out, the roller is driven to rotate by virtue of friction force between the driving roller and the roller, so that film releasing operation is realized, however, a series of defects are exposed after long-term use in the driving mode, on one hand, due to friction loss between the driving roller and the roller, slipping phenomenon is very easy to occur, on the other hand, the film releasing speed of the protection film is unstable, so that film releasing is uneven, the attaching quality of the protection film on the surface of the power battery is seriously influenced, the protection effect is reduced, on the other hand, when the roller is mounted, the operation process is quite complicated, a worker needs to detach a baffle plate on one side of the driving roller firstly, and then mount the baffle plate again after the roller is mounted in place, so that a great amount of time and effort are consumed, labor cost is increased, related parts are also possibly worn, the service life of equipment is reduced, and great inconvenience is brought to production and maintenance work. Therefore, it is necessary to provide a new power battery protection film for new energy vehicles to solve the above technical problems. Disclosure of utility model In order to solve the technical problems, the utility model provides a power battery protection film for a new energy automobile. The power battery protection film for the new energy automobile comprises a roller, wherein the outer wall of the roller is wound with the protection film, a driving roller is arranged in the roller, clamping blocks are symmetrically and slidingly connected to the middle of the inner wall of the roller, and a limiting assembly for driving the clamping blocks to retract into the roller is arranged in the roller.
