Compared with prior art, the utility model has technical effect beneficial below:
The utility model between composite layer by being arranged sealant, to play the role of sealing, is guaranteeing again
Condensation material battery case is light-weighted simultaneously, meets requirement of the battery box cover for air-tightness.Electro-magnetic screen layer is also set up simultaneously, it can
To meet requirement of the electrokinetic cell system for battery case in terms of electromagnetic shielding.
Further, using the fibrofelt of coated with resins as sealant, due to the composite wood of carbon fiber prepreg preparation
Expect that resin content is lower in battery box cover, preparation process is influenced that resin cannot be made full full of entire case lid type face by production efficiency
The requirement of sufficient air-tightness, and the content of resin in fibrofelt can be made to reach very high by the way of the coated with resins on fibrofelt
Degree, product entire case lid type face is full of in solidification process, to play the role of further increasing air-tightness.
Further, the first composite layer and the second composite layer are all made of phenolic resin reinforcing fiber, phenolic aldehyde tree
Rouge forms fine and close carbon-coating and the intensity of a fire is prevented to wash away and spread, so that this is practical because of its carbon yield with higher at high temperature
Novel battery case lid has fire-proof function.
Further, the thickness of the first composite layer and the second composite layer is very small, can further lightweight,
Meanwhile the presence of sealant makes battery case still meet air-tightness requirement.
Further, there is the utility model case lid manual maintenance to switch mounting hole, and installation manual maintenance switch can be protected
It protects and repairs technical staff's safety of electric car or the event of strain burst under hyperbaric environment, it can be with quick separating high-tension circuit
Connection, make the work such as maintenance for a kind of safer state, such as external short circuit situation are protected, when maintenance needs to disconnect high
Pressure.
