Abstract
The utility model discloses a kind of car door inner board, including inner panel body, the arc corner of the bottom of the inner panel body is provided with convex closure, and at least provided with three, and arcuately, the radian of corner is set the convex closure.The utility model is simple, design contract, and convex closure is set by the corner in inner plate of car door bottom, can be prevented effectively from cracking corrugation of the inner plate of car door in drawing process is made, simplify manufacturing process, improve production efficiency, improve the overall aesthetics of product.
Description
Technical field
The utility model belongs to technical field of automobile parts, and in particular to a kind of car door inner board.
Background technology
With making rapid progress for auto industry, pursuit of the people to automotive trim is also being improved constantly.It is used as automotive trim
Important part --- inner plate of car door, comfortableness, aesthetic property, reliability increasingly become the target of people's pursuit.It is existing
The arc corner of car door inner board bottom, in manufacturing process, car door blank is in drawing process, and the maximum for having material is cut
To pressure at angle of flange it is maximum, no matter pressure-pad-force is much when material is stretched or any adjustment of Drawbead Restraining Force coefficient, this
Corner root can all wrinkle, therefore, and the inner plate of car door of existing structure has that production process is cumbersome, resilience is difficult, aesthetics
Not good enough the problems such as.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of car door inner board.
A kind of described car door inner board, including inner panel body, it is characterised in that the arc of the bottom of the inner panel body
Shape corner is provided with convex closure, and at least provided with three, and arcuately, the radian of corner is set the convex closure.
Described a kind of car door inner board, it is characterised in that the convex closure integral type is arranged on inner panel body.
Described a kind of car door inner board, it is characterised in that the convex closure is oval to be set.
Described a kind of car door inner board, it is characterised in that the convex closure total length is 16-21mm, convex closure overall width is
7-12mm。
Described a kind of car door inner board, it is characterised in that the convex closure total length is 19mm, convex closure overall width is
10mm。
The utility model is simple, design contract, sets convex closure by the corner in inner plate of car door bottom, can be prevented effectively from
Cracking corrugation of the inner plate of car door in drawing process is made, simplifies manufacturing process, improves production efficiency, improve the overall U.S. of product
Sight degree.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1- inner panel bodies, 2- convex closures.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in figure 1, a kind of car door inner board of the utility model, including inner panel body, to improve U.S. of inner panel body
Sight degree and simplified production process, the arc corner integral type in the bottom of inner panel body are provided with convex closure, and the convex closure is at least set
Three are equipped with, and arcuately the radian of corner is set, by experimental test, the anti-corrugation ability of convex closure of elliptical shape is most
By force, and convex closure total length be 16-21mm, convex closure overall width be 7-12mm, optimal is that convex closure total length is 19mm, and overall width is
10mm.The convex closure that the size is set can effectively prevent the corrugation of inner plate of car door bottom corner.
The utility model in the bottom of inner plate of car door by setting simple convex closure structure, you can solves stretching corrugation and opens
Problem is split, in the drawing process corner because the tangential longitudinal stress of material over time is uneven, and because of material and mould in drawing process
Tool both sides are that material can change to height undulating state since flat material in vacant state, therefore drawing process, and convex closure now exists
Material starts after undulating state, is not yet formed before fold, is molded along heave direction, so as to eliminate fold.So as to reduce car door
The manufacturing process of inner panel, improves production efficiency.
