Description
Technical field
A kind of lightweight fire prevention case lid of composite battery case is the utility model is related to, belongs to new-energy automobile field.
Background technology
New-energy automobile enters the also constantly lifting, therefore right such as the period developed rapidly, the energy density of electrokinetic cell
The attention rate of the cell safety problem of high-energy-density also more and more higher.Lightweight is the important side of current Development of Electric Vehicles
To, be energy-saving and emission-reduction important means.As the battery box cover of electric automobile key position, its lightweight is also to improve vehicle to continue
The important channel of boat mileage.Existing battery box cover one is welded using traditional sheet metal, and weight is heavier, causes
Energy density is relatively low, influences the continuation of the journey of electric automobile, and metal battery case lid needs to carry out follow-up insulation processing, such as increases exhausted
Edge coating, felt pad, insulation board etc. further increase weight；Second, it is made of composites such as epoxy base carbon fibres, such a case lid
Material later stage of not preventing fires in itself needs to carry out various fire prevention processing, such as brushes in fireprotection layer or mold process plus fireprotection layer, this
The composite case lid that a little modes produce not only complex production process, and fireprotection layer is easily peeled off with multiple material.
Utility model content
In view of the shortcomings of the prior art, it is multiple to provide a kind of lightweight fire prevention for New-energy electric vehicle for the utility model
Condensation material battery box cover.
To achieve these goals, technical scheme is used by the utility model solves its technical problem：One kind is used for
The lightweight Flameproof composite material battery box cover of New-energy electric vehicle, including box cover body, the box cover body is by outer layer glass
Glass fibrous layer, basalt fiber, carbon fiber layer and inner layer glass fibrous layer composition, the outside both ends for including box cover body are set
Opening hand draw ring is equipped with, the outer side edges of box cover body are provided with threaded connection seat, the both ends for opening hand draw ring and case
Lid body links into an integrated entity structure, and the threaded connection seat also becomes one structure with box cover body, on the threaded connection seat
Tapped through hole is provided with, support triangle plate is provided between the downside of threaded connection seat and the lateral wall of box cover body
Reinforcement, the inside edge of the box cover body are provided with closure gasket groove.
A kind of lightweight Flameproof composite material battery for New-energy electric vehicle that the utility model further provides for
Case lid, the top layer of its inner layer glass fibrous layer are also coated with one layer of resin bed.
A kind of lightweight Flameproof composite material electricity for New-energy electric vehicle that the utility model further provides
Pond case lid, the thickness of its box cover body is 0.2-0.5cm.
The beneficial effects of the utility model：The lightweight fire prevention case lid of the utility model composite battery case has fire prevention
The features such as grade height, light weight, intensity height, convenient formation, resistant to chemical etching and good weatherability, excellent insulation performance.
