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. 1-4, a kind of 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.
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.
Power battery top cover, centre are equipped with explosion-proof valve and liquid injection hole, and power battery top cover top and bottom and pole and aluminium block are pre-
The processing of first nanosizing forms nano aperture in metal surface, then with nmt technology nanometer injection moulding plastic, pole and aluminium block are fixed
It 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.
Power battery top cover top and bottom and the preparatory nanosizing processing of pole and aluminium block, form nano aperture in metal surface,
It is molded insulated plastic in positive nanometer, so that positive terminal and coping plate electrical isolation, protect battery case.It is exhausted in the injection molding of cathode nanometer
Edge plastic cement, so that negative terminal and top cover electrical isolation.
After above-mentioned structure,
1. the upper and lower insulation board of top cover and sealing ring are all replaced with NMT nanometers of injection moulding plastics, reduce unnecessary knot
Structure part, significantly reduces quality, has saved cost.
2. utilize NMT nanometer injection molding insulated plastics in anode so that positive terminal and top cover are electrically connected, save resistor disc,
Insulating part and sealing element.
3. by the close connection of nmt nanometers of injection moldings, thus having good sealing performance, security performance is high, extends close
The useful life of envelope, while also extending the service life of battery.
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
