Description
Technical field
The utility model belongs to miniature electric automobile auto body technique field, is specifically related to a kind of lightweight vehicle body of miniature electric automobile.
Background technology
The lightweight of automobile is operated in more and more to be paid attention in the world, one after another in research.Auto body accounts for 30% of automobile total mass, under no-load condition, and the electricity of about 70% is used on body quality, must alleviate deadweight to improve for the purpose of car load economy.The lightweight of automobile contributes to the raising of " travel, turn, stop " three large key propertys of automobile.For pure electric automobile, the pollution that lightweight can not only reduce consumption for the energy and environment is carried out to vehicle body, the course continuation mileage of pure electric automobile can also be improved significantly, body lightening design is carried out to pure electric automobile and just seems particularly important.
In order to reduce vehicle weight, engineer mainly tries every possible means from material, technique and structure.One, be that design is optimized to body structure.Namely modified node method, reduce amount of parts, make parts thin-walled property, cavitation, miniaturization, all car body components such as Composite and interior trim, driving engine and chassis carry out structural development; Structure optimization is carried out to vehicle body parts, under the prerequisite meeting design performance requirement, to obtain minimum weight structure design.The method major advantage is that cost is low and easily realize, and especially for from part that is great, complicated structure, this method has very large application space.Two, application new material can not increase the burden on the cost of automobile; Car production is the typical case of large-scale production, and because product batch is huge, floating on the cost of any point all can bring pressure to manufacturer and client.
Utility model content
For prior art Problems existing, the purpose of this utility model is to design the technical scheme of the lightweight vehicle body providing a kind of miniature electric automobile.
The lightweight vehicle body of described a kind of miniature electric automobile, it is characterized in that comprising body platform body, described body platform body front portion is provided with front right longitudinal beam and left front girder, front cross rail and after cross member is provided with in the middle part of described body platform body, described body platform body rear portion is provided with right back longeron and left rear longitudinal beam, described front cross rail two ends are fixed with front right longitudinal beam and left front girder respectively, described after cross member two ends are fixed with right back longeron and left rear longitudinal beam respectively, battery case installation position is formed between described front cross rail and after cross member, battery case is fixedly installed in described battery case installation position, the metal plate material that described battery case is 1.5mm by thickness is made, described battery case surrounding by arrange hanger and body platform body fix.
The lightweight vehicle body of described a kind of miniature electric automobile, is characterized in that described body platform body both sides are fixedly installed battery case right mounting bracket and battery case left installation bracket.
The lightweight vehicle body of described a kind of miniature electric automobile, it is characterized in that the front end of described battery case is by arranging two hangers and front cross rail is fixed, the rear end of described battery case, by arranging three hangers and after cross member is fixed, holds each hanger and battery case left installation bracket and battery case right mounting bracket of arranging to fix about described battery case.
The lightweight vehicle body of above-mentioned a kind of miniature electric automobile, reasonable in design, by the arrangement of the crossbeam on rational deployment's body platform and longeron, remove in existing body platform battery case installation position and organize longeron more, the intensity of reinforcement body platform is carried out by battery case and crossbeam and the mode that is fixedly connected with of longeron, while ensureing body stiffness, gently change vehicle body to greatest extent.In addition, the utility model adds the point of connection of battery case and body platform, improves stability and the fastness of battery installation.
