Abstract
The utility model discloses a light weight small back door. A smooth surface is formed on the outer side of an outer door sheet, a plurality of vertical ribs are arranged on the inner side of the outer door sheet, fixed mounting holes are formed in the vertical ribs and the local thickness of each vertical rib in a contact part between each vertical rib and the inner wall of the outer door sheet is less than that of each vertical rib located on the upper middle part of the outer door sheet; continuous grooves are formed in an injection moulded frame skeleton, alternately arranged reinforcing ribs are arranged in the grooves, and the frame skeleton is fixed on the inner side of the outer door sheet through fastening screws. According to the light weight small back door provided by the utility model, the texture of the rear back door is defined to be plastic; furthermore, the small back door is formed by fixing the bolts and the skeleton made from engineering plastics and integrally combining the engineering plastics, therefore, the strength requirement can be met and meanwhile the weight of a vehicle body can be reduced.
Description
Technical field
The present invention relates to electric automobile gate technique field, specifically the little back door of a kind of weight-saving.
Background technology
Along with the lasting increase of resource and environment dual-pressure, the further genralrlization strategy of sustainable development is imperative, and electronlmobil becomes future automobile industrial expansion direction at last.
From market capacity, technical merit that China is current, low-speed electronic automobile has that economic performance is good, energy-conserving and environment-protective, economize on resources, the advantage such as use cost is low, charging is convenient, most economical, the most environmental protection in two, three line cities, the vehicle the most easily promoted, be the strategic choice that China realizes green traffic.
For realizing the development of low-speed electronic car, the selection of car body component material is most important, but at present conventional automobile door outside plate many employings steel plate punched forms, for low-speed electronic car but and inapplicable.
Orthodox car is the intensity ensureing car body, and its back door off-grade plate mainly adopts steel plate punched to form.Its shortcoming is that car door entirety is heavier, and shaping energy consumption is large, and cost is higher, changes more difficult.
And as low-speed electronic automobile, for reaching reduction cost of product, make car load lightweight, improve the F-Zero of electronlmobil and extend the object of car load mileages of continuation, back door outside plate material is changed to engineering plastics by the present invention, engineering plastics have the features such as excellent mechanical characteristics, electrical property, chemical resistance, resistance to effect of heat, resistance to abrasion, dimensional stability, and less energy consumption time lighter, shaping than the steel plate materials that will replace, and change conveniently.Then back door bulk strength and safety is ensured by the injection moulding skeleton of engineering plastics.
Summary of the invention
In order to make battery-driven car lightweight, thus accelerate car load moving velocity and extend travelled distance and design, and a difficult problem for some the Shooting Technique aspects occurred in the process to be overcome, the little back door of weight-saving of a kind of non-metallic material of the present invention, use engineering plastics to make completely.
The present invention solves the technical scheme that its technical matters takes: the little back door of a kind of weight-saving, is characterized in that, comprise
The external door panel of one injection mo(u)lding, outside described external door panel, there is smooth surface, inside described external door panel, be provided with some studs, described stud is provided with fixed installation hole, and be less than middle and upper part stud thickness with the described stud local thickness at external door panel contact internal walls position
The section of one injection mo(u)lding is the shaped as frame skeleton of a few font, has continuous print groove in described skeleton, and is provided with spaced apart reinforced rib in described groove, and described shaped as frame skeleton is fixed on inside external door panel by tightening screw.
Further, the edge fastened in described external door panel and skeleton is provided with buckle structure.
Further, be 1/2nd of described stud middle and upper part thickness with the described stud thickness at external door panel contact internal walls position, that is, the thickness of described stud middle and upper part is more than 2 times of stud bottom thickness.
Further, be provided with door lock in the downside of described skeleton and notch is installed.
The invention has the beneficial effects as follows: back door material is defined as plastic material by the present invention, fixed by the skeleton of bolt and engineering plastics material, the overall engineering plastics that adopt are composited, and reduce the weight of vehicle body while meeting requirement of strength.
The present invention can effectively alleviate Vehicle preparation quality, thus realizes the lightweight of low-speed electronic car, and realizes the raising of car load F-Zero and the increase of continual mileage.
In large-area panel injection molding process, stress can be produced at the position that stud contacts with external door panel, the external door panel outside face stud is corresponding is caused to there will be inotropic depression, cause the reduction of surface quality, the present invention is by becoming thin-walled by stud localized design, namely at the described stud thinner thickness with external door panel contact internal walls position, well solve this problem, make being molded in order to possibility of large-area door panel.

Detailed description of the invention
As shown in Figures 1 to 5, the little back door of a kind of weight-saving, adopts the external door panel of engineering plastics material and skeleton to be composited.
Wherein, the external door panel 1 of an injection mo(u)lding, integral molded plastic is shaping, has good outward appearance and aesthetics.Outside external door panel 1, there is smooth surface, some studs 11 are provided with inside external door panel 1, the section decision design of stud is U-shaped, there is higher intensity, described stud is provided with fixed installation hole 12, can be used for tightening screw, and with the described stud thinner thickness at external door panel 1 contact internal walls position, particularly, the thickness of described stud middle and upper part 111 is more than 2 times of stud bottom 112 thickness.This structure design, solves the problem producing depression in the front of the external door panel being provided with stud, makes the injection mo(u)lding of large-area back door become possibility, and can ensure the attractive in appearance of outside face.
The shaped as frame skeleton 2 of one injection mo(u)lding, section is a few font, adopts engineering-plastics integral injection mo(u)lding.In described skeleton, have continuous print groove 21, section is rendered as a few font, is provided with spaced apart reinforced rib 22 in described groove, for improving overall intensity, being provided with door lock installing notch 23, for installing lockset in the downside of described skeleton.Described shaped as frame skeleton 2 is fixed on inside external door panel 1 by tightening screw, forms a kind of composite component with concrete structure.Meanwhile, the edge fastened in external door panel and skeleton is provided with buckle structure, and both can be made like this to keep good fastening effect in an assembling process.
The present invention can substitute the roadlice back door of existing sheet metal structural completely, meets the requirement that electronlmobil uses.
Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
