Abstract
A kind of lightweight back door outside plate, outside described external door panel, there is smooth surface, the U-shaped stud of some interrupted settings is provided with inside described external door panel, 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, and reserved back door installs window in described external door panel, and inside described external door panel, be provided with the some screw holes installing window setting along back door.In large-area door panel injection molding process, stress can be produced at the position that stud contacts with door panel, the door panel outside face stud is corresponding is caused to there will be inotropic depression, cause the reduction of surface quality, the utility model 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.
Description
Technical field
The utility model relates to electronlmobil skinning technique field, specifically a kind of lightweight back door outside plate.
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.
For realizing the development of low-speed electronic car, the selection of car body component material is most important, but at present orthodox car back door outside plate is many is made up of full-scale punching press outside plate, full-scale punching press inner panel and the support be embedded between inner and outer plates, last outside plate and inner panel assembly are closed by bound edge mode, however this scheme for low-speed electronic car but and inapplicable.
Orthodox car is for ensureing back door intensity and safety, and its back door outside plate mainly adopts steel plate punched to form.Its shortcoming is that back 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 logical peraluminous skeleton cooperation ensures bulk strength and safety.
Utility model content
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 will be overcome, a kind of lightweight back door of the utility model outside plate.
The technical scheme in the invention for solving the technical problem is:
A kind of lightweight back door outside plate, is characterized in that, comprise
The external door panel of one injection mo(u)lding, outside described external door panel, there is smooth surface, be provided with the U-shaped stud of some interrupted settings inside described external door panel, described stud be 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.
Further, in described external door panel, reserved back door installs window, and inside described external door panel, be provided with the some screw holes installing window setting along back door.
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.
Described door skin is fixed on described aluminum skeleton by fastener, and this aluminum skeleton is the framed structure formed by welding by aluminium alloy pipe and aluminum alloy blanked part.
The beneficial effects of the utility model are:
Door skin material is defined as plastic material by the utility model, is fixed by bolt and aluminium matter Vehicle door frame, ensures car door bulk strength and safety with Vehicle door frame.
The utility model 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 door panel injection molding process, stress can be produced at the position that stud contacts with door panel, the door panel outside face stud is corresponding is caused to there will be inotropic depression, cause the reduction of surface quality, the utility model 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.
Accompanying drawing explanation
Fig. 1 is the block diagram (back side) of door skin.
Fig. 2 is A--A cutaway view in Fig. 1.
Fig. 3 is the block diagram (front) of door skin.
Fig. 4 is the front view of Fig. 1.
In figure: 1 external door panel, 11 stud middle and upper parts, 12 stud bottoms, 13 back doors install window, 14 screw holes, 2 studs, 21 fixed installation holes.
Detailed description of the invention
As shown in Figures 1 to 4,
A kind of lightweight back door outside plate, comprise the external door panel 1 of an injection mo(u)lding, there is certain radian, outside described external door panel, there is smooth surface, there is good appearance, inside described external door panel 1, be provided with some U-shaped studs 2, described stud is provided with fixed installation hole 21, mounting hole is taper platform hole, fastening for screw, and with the described stud place thinner thickness at external door panel 1 contact internal walls position.Best, the thickness of stud middle and upper part 11 is more than 2 times of stud bottom 12 thickness, can reduce stress during injection moulding, makes the outside face smoother of external door panel 1.In described external door panel, reserved back door installs window 13, and inside described external door panel, be provided with the some screw holes 14 installing window 13 setting along back door.
Described door skin 1 is fixed on described aluminum skeleton by fastener, and this aluminum skeleton is the framed structure formed by welding by aluminium alloy pipe and aluminum alloy blanked part.This automobile door structure at least alleviates more than 2/3rds than the car door quality of panel beating metal, and intensity does not then reduce substantially.
Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
