Description

A kind of cooperation power battery top cover
Technical field
The utility model belongs to battery technology field more particularly to a kind of cooperation power battery top cover.
Background technique
Currently, the covering plate structure of power battery generallys use cover board matrix, copper aluminium pole, the molding work of upper and lower plastic-injection Skill carries out machine-shaping,
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems: the cover board knot The quality of structure monomer is larger.
Utility model content
The technical problem to be solved by the utility model is to provide the cooperation power of a kind of guarantee safety and mitigation weight Battery cap.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of cooperation power battery top Lid, comprising:
Top cover body;
Pole is mounted in the top cover body;
Aluminium block is mounted on the pole, and the aluminium block is contacted with the top cover;
The face that the top cover body, pole, aluminium block contact between each other is connected by nanometer moulding;
It is second nanometer of injection moulding plastic between the top cover body and aluminium block, second nanometer of injection moulding plastic is equipped with Card slot, the aluminium block are equipped with the fixture block being adapted to the card slot.
The nanometer moulding makes the top cover body, pole, aluminium block be connected as one formula structure.
The face that the top cover body, pole, aluminium block contact between each other is equipped with nano aperture.
The pole includes positive terminal and negative terminal, and the aluminium block includes positive aluminium block and cathode aluminium block, the positive terminal It is connect with positive aluminium block, the negative terminal is connect with the cathode aluminium block.
Nanometer moulding between the positive terminal and top cover body is insulated plastic;The negative terminal and top cover body it Between nanometer moulding be insulated plastic.
Explosion-proof valve is equipped in the middle part of the top cover body.
Liquid injection hole is equipped in the middle part of the top cover body.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect,
Cover plate of power battery, due to being sealed between pole and cover board matrix by nanometer injection molding, which can be allowed Connection sheet is closely connect with cover board matrix by nmt technology, thus has good sealing performance, and security performance eliminates close Seal and insulated plastic offset plate, alleviate weight.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cooperation power battery top cover provided in the utility model embodiment;
The partial enlarged view for the cooperation power battery top cover that Fig. 2 is Fig. 1;
Label in above-mentioned figure is equal are as follows: 1, lamina tecti, 2, explosion-proof valve, and 3, liquid injection hole, 4, positive terminal, 5, positive aluminium block, 6, Negative terminal, 7, cathode aluminium block, 8, first nanometers of injection moulding plastics, 9, second nanometers of injection moulding plastics.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type embodiment is described in further detail.
Referring to Fig. 1-2, a kind of cooperation power battery top cover, comprising:
Top cover body;
Pole is mounted in top cover body;
Aluminium block is mounted on pole, and aluminium block is contacted with top cover;
The face that top cover body, pole, aluminium block contact between each other is connected by nanometer moulding;
It is second nanometer of injection moulding plastic between top cover body and aluminium block, second nanometer of injection moulding plastic is equipped with card slot, aluminium Block is equipped with the fixture block being adapted to card slot.Shape is formed between pole and aluminium block and coping plate plays fixed function.
Nanometer moulding makes top cover body, pole, aluminium block be connected as one formula structure.
NMT (Nano Molding Technology) be metal with plastic cement with the engineering method in conjunction with nanotechnology, first by metal After nanosizing is handled, plastic cement direct injection allows metal can be integrally formed with plastic cement, not only in metal surface on surface Metal appearance texture can be taken into account, the design of product construction part is also can simplify, makes product lighter, thin, short, small, and compared with CNC engineering method It is more cost effective.After NMT technology can remove rust, the grease of thin metal surface, it is surface-treated through special solution, Therefore metal material has aperture, then metal material is put into mold and carries out injection molding, enters plastic cement in aperture and solidifies, Achieve the purpose that strong engagement.
Pole includes positive terminal and negative terminal, and aluminium block includes positive aluminium block and cathode aluminium block, and positive terminal and positive aluminium block connect It connects, negative terminal is connect with cathode aluminium block.
Explosion-proof valve is equipped in the middle part of top cover body.Liquid injection hole is equipped in the middle part of top cover body.
Cooperate power battery top cover, centre is equipped with explosion-proof valve and liquid injection hole, cooperates power battery top cover top and bottom and pole With aluminium block preparatory nanosizing processing, form nano aperture in metal surface, then use nmt technology nanometer injection moulding plastic, by pole with Aluminium block fixation is bonded on top cover, so that pole and aluminium block electrical connection, and make positive and negative terminals and top cover insulation, aluminium block and top cover Insulation.
Cooperate power battery top cover top and bottom and pole and the preparatory nanosizing processing of aluminium block, forms nano-pore in metal surface Hole is molded insulated plastic in positive nanometer, so that positive terminal and coping plate electrical isolation, protect battery case.It is infused in cathode nanometer Insulated plastic is moulded, so that negative terminal and top cover electrical isolation.
After above-mentioned structure,
Cover plate of power battery, due to being sealed between pole and cover board matrix by nanometer injection molding, which can be allowed Connection sheet is closely connect with cover board matrix by nmt technology, thus has good sealing performance, and security performance eliminates close Seal and insulated plastic offset plate, alleviate weight.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model Protection scope within.
