Description
Technical field
The present invention relates to a kind of electric bicycle shell and production technology thereof, relate in particular to a kind of half bearing-type modular composite electric bicycle shell and production technology thereof.
Background technology
Four-wheel electric motor car is the direction of new forms of energy vehicle development.Domestic and international electronic car trader considers the weight-saving reason at present, mainly adopts composite material to make the car shell of battery-driven car.Closed eggshell structure is adopted in the manufacturing of domestic battery-driven car composite car shell usually; Both car load car shell had the independent bumper/spoiler except left and right door, front and rear covers and indivedual vehicle; All the other car shells partly are an osed top egg-shell type structure (see figure 1); The egg-shell type inside configuration does not have the bulk metal skeleton of bearing-type, and the egg-shell type structure adopts the composite material hand to stick with paste explained hereafter.
Egg-shell type structural composite material car shell is a self-supporting body, and vehicle body is born whole load, so the car shell is thick, weight is big.Because body structure is an egg-shell type housing, single small product size is big, and opening surface is many; Curved surface is complicated, so must adopt hand to stick with paste explained hereafter, product design is not easy control; Product quality is low, and the part is easy to generate distortion, and production process is loaded down with trivial details; The single housing production cycle is long, requires to have bigger production site.Because the egg-shell type vehicle body is big, mould is complicated, is difficult to product is heated the back cured, so products solidifying receives the influence of ambient temperature, humidity easily.Many and a plurality of miscellaneous parts of egg-shell type vehicle body opening part have faying face, and the human element that hand is stuck with paste in the operating process causes the local deformation at composite-material body position easily, cause parts assembling difficulties such as car door.Simultaneously, because whole egg-shell type vehicle body molding procedure is loaded down with trivial details, product and mould are big; Can't carry out heating cure to product, so, the battery-driven car vehicle body that adopts no support framework sealing egg-shell type structure to produce; Production efficiency is low; Homogeneity of product is poor, and the fitted position precision is low, can't satisfy the mass demand of battery-driven car development.Because must adopt hand to stick with paste technology, product design is limited by production environment and single employee's production skills and sense of responsibility, so, be difficult to guarantee the quality conformance of product, more can't realize the standardized production and the interchangeability that satisfies parts of car shell.
Goal of the invention
The deficiency that exists to prior art, but the object of the present invention is to provide a kind of rational in infrastructure, convenient for production, install simple, size is accurate, the composite material electric bicycle shell of the low mass of weight, standardized production;
Another object of the present invention is to provide the production technology of this electric bicycle shell.
Goal of the invention of the present invention realizes through following technical scheme.
A kind of half bearing-type modular composite electric bicycle shell; Comprise the body framwork that shape is processed; Modular car parts; Said car case member is the composite car case member that adopts hand paste, vacuum bag pressure, lightweight RTM (Resin Transfer Molding) or SMC (SMC is the abbreviation of English sheet molding compound " sheet moulding compound ") explained hereafter, and said car shell module is connected on the metal body skeleton.
The connection mode of said car shell module and metal body skeleton is a kind of in following two kinds of connection modes: first kind is attachment hardware to be bonded on the connection location of car shell modular unit through structural adhesion, and attachment hardware is rigidly connected through metal connection mode and metal body skeleton again; Second kind is on the modular unit connection location, to punch the hole in advance; Piercing aperture is greater than connecting the metal screw diameter; Band and the metallic gasket that screw coupling aperture is installed are bonded in punch position with structural adhesion, guarantee that two holes are coaxial, use then the metal screw with the modular member direct connection on skeleton.Structural adhesion is epoxy structural rubber or ketone structural adhesion.
Said car shell module be with whole car shell by body shape and composite material forming characteristics be divided into car door, front and rear covers, light deflector, front and back bumper/spoiler, top cover, about inboard, inboard these the several standard modules in back door.According to the said car shell of different automobile types module also comprise before shelves glass modules with about before the wheel arch module.
The production technology of this half bearing-type modular composite electric bicycle shell comprises the steps:
1), adopt hand paste, vacuum bag pressure, lightweight RTM or SMC technology to make car shell module;
2) but, the structure of pressing vehicle body with shape makes the body framwork of a bearing load;
3), car shell module is connected with the metal body skeleton through the mode of being rigidly connected.
The connection mode of said car shell module and metal body skeleton is a kind of in following two kinds of connection modes: first kind is attachment hardware to be bonded on the connection location of car shell modular unit through structural adhesion, and attachment hardware is rigidly connected through metal connection mode and metal body skeleton again; Second kind is on the modular unit connection location, to punch the hole in advance; Piercing aperture is greater than connecting the metal screw diameter; Band and the metallic gasket that screw coupling aperture is installed are bonded in punch position with structural adhesion, guarantee that two holes are coaxial, use then the metal screw with the modular member direct connection on skeleton
Half bearing-type modular composite battery-driven car shell structure provided by the invention is owing to adopted metal frame and rigidly connected half bearing mode of car case member, composite material component can reduce strength of material, minimizing material weight and cost; Because metallic framework has been arranged; The car shell of originally whole egg-shell type can be divided into a plurality of little modular members, and these parts more can adopt vacuum bag to press and lightweight RTM production technology except adopting the hand pasting forming; And can heat to parts; Guarantee the curing degree of product, reduce the influence of human element in the manufacture course of products, environmental factor, improve production efficiency of products greatly product distortion, dimensional stability; Reduced manufacturing cost; Controlled the quality of product effectively, can realize mass, the standardized production of composite car shell, also make battery-driven car composite car shell product quality conformability and with the interchangeability of base part had realize maybe.
