Embodiment
[0051] Refer below Figure 1-Figure 5 A battery top cover according to a specific embodiment of the present invention is described.
[0052] Such as Figure 1-Figure 5 As shown, the battery top cover includes a top cover sheet 1, a positive pole column 2, a negative pole column 3, a plastic part 4, and an explosion-proof valve 5. The top cover sheet 1 is provided with a positive electrode hole, a negative electrode hole liquid injection hole 11, and an explosion-proof hole. 2 fits in the positive pole hole, and the negative pole post 3 fits in the negative pole hole. The plastic part 4 includes a main body 41 and a wing 42 , the main body 41 abuts on the inner side wall of the top cover sheet 1 . The main body 41 is provided with an explosion-proof protrusion 416 corresponding to the explosion-proof hole and a perforation 415 corresponding to the liquid injection hole 11 . The two wing plates 42 are respectively located at two ends of the explosion-proof protrusion 416 , an...

The invention discloses a battery top cover and a power battery. The battery top cover comprises a top cover sheet, a positive pole column, a negative pole column and a plastic piece, wherein the topcover sheet is provided with a positive pole hole and a negative pole hole, the positive pole column is matched in the positive pole hole, the negative pole column is matched in the negative pole hole, the plastic piece comprises a main body and wing plates, the main body abuts against the inner side wall of the top cover sheet, the number of the wing plates is two, one ends of the two wing platesare rotatably connected to the two ends of the main body respectively, the other ends of the two wing plates can be clamped to the main body, the wing plates have buckling positions and releasing positions, at the buckling positions, the other ends of the wing plates are clamped to the main body and the wing plates and the main body are arranged in parallel, and at the releasing positions, the other ends of the wing plates are disengaged from the main body. According to the invention, the plastic piece of the battery top cover comprises the wing plates which are rotatably matched with the main body, so that the plastic piece can play a role in protecting the connecting sheet, the number of the parts of the battery top cover is reduced, the assembly process is simplified, the production cost is reduced, and the manufacturing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of energy equipment, in particular to a battery top cover and a power battery. Background technique [0002] The bottom of the power battery pole usually needs to be protected by a film after welding the connecting piece, or two additional plastic cages are added to protect the connecting piece. The above two methods will increase the number of parts of the battery top cover, thereby increasing the assembly process of the battery top cover, increasing the manufacturing cost of the battery top cover, and reducing the assembly efficiency of the battery top cover. Contents of the invention [0003] The first object of the present invention is to provide a battery top cover, which has a simple structure, low manufacturing cost and high assembly efficiency. [0004] The second object of the present invention is to provide a power battery, which has a relatively simple structure, low manufacturing cost and high...
