Abstract

A kind of horizontal not uniform thickness automobile door sill reinforcer, it is characterised in that it is linear structure on length direction that its body is in vehicle body XZ planes；Body is that width is open Cap-style Section in vehicle body YZ planes, and section is replaced by straightway with arc section to be formed, comprising more than 2 arc sections, and, more than one thickness, arc section area thickness t on section be present₀More than any straightway area thickness { t₁,t₂,…,t_i,…,t_n, straightway region quantity n is the integer more than 2；Thickness transitions region between straightway and arc section is provided with intermediate incline.There is change in the utility model thickness on part section direction, to realize that part light-weight design manufactures with low cost.

Description

A kind of horizontal not uniform thickness automobile door sill reinforcer

Technical field

Forming technique is the utility model is related to, more particularly to a kind of horizontal not uniform thickness automobile door sill reinforcer.

Background technology

Automobile door sill reinforcer is located at vehicle body both sides bottom of door, for the head-on crash, side collision and car of automobile Body rigidity has a major impact, and is structure-bearing part crucial on vehicle body.Different zones material collides for part on section Performance contribution is different, material can be carried out in part less region loaded it is appropriate be thinned, so as to realize lightweight simultaneously Save material.A kind of new automobile door sill reinforcer is devised, its raw material is conventional equal thickness material, passes through special roller Pressure technique realizes change of the thickness on product cross section, while part performance requirement is met, it is possible to achieve further light weight Change, and reduce parts manufacturing cost.

China Patent Publication No. CN104943753 A describe a kind of Varying-thickness automobile door sill reinforcer and its manufacturer Method, this method use unequal thickness plate, finally realize thickness change on part length direction.

China Patent Publication No.：CN 104443061A " automobile door sill reinforcing structure and automobile " describe a kind of car door The design method of sill local strengthening muscle, to strengthen doorsill structure intensity；

China Patent Publication No. CN 201613947U describe a kind of tabular reinforcer being arranged in threshold, to improve Threshold reinforcer rigidity.

Automobile buffer beam described in above patent is by increasing local reinforcer, or by using part length direction not Strengthen the local strength of threshold reinforcer Deng the mode of slab, had differences with design as described herein

The content of the invention

The purpose of this utility model is to design a kind of horizontal not uniform thickness automobile door sill reinforcer, on part section direction There is change in thickness, to realize that part light-weight design manufactures with low cost.

To reach above-mentioned purpose, the technical solution of the utility model is：

A kind of horizontal not uniform thickness automobile door sill reinforcer, it is characterised in that its body is length direction in vehicle body XZ planes Upper is linear structure；Body is that width is open Cap-style Section in vehicle body YZ planes, and section is by straightway and arc section Alternately form, comprising more than 2 arc sections, and, more than one thickness, arc section area thickness t on section be present₀It is more than Straightway area thickness { t₁,t₂,…,t_i,…,t_n, straightway region quantity n is the integer more than 2；Straightway and arc section Between thickness transitions region be provided with inclined-plane.

Preferably, the arc section thickness t0 of described body section and any straightway thickness ratio are 1~2.5.

Preferably, the angle, θ scope on the body section thickness transitional region inclined-plane is 15~75 °.

Preferably, the body section thickness transitional region transition region is apart from arc section fillet root distance L >=3mm.

The utility model can be used for conventional cold rolling and hot rolling ferrous materials, it can also be used to other gold such as aluminium alloy, magnesium alloy Belong to material.

Compared with prior art, the utility model has the following advantages that：

1. raw material are conventional equal thickness material used by the utility model, without laser welding or Varying-thickness rolling work Skill, the cost of raw material are low；

2. process advantages of simple provided by the utility model, material preprocessing process can shape work with regular roll Skill is integrated, and to realize that continuity is processed, production efficiency is high；

3. in the utility model, material carries out thickness by preprocessing process and redistributed, realize it is light-weighted simultaneously, Part raw materials consumption can be reduced.

Embodiment

Referring to Fig. 1~Fig. 3, a kind of horizontal not uniform thickness automobile door sill reinforcer of the present utility model, it is characterised in that its It is linear structure on length direction that body 1 is in vehicle body XZ planes；Body is that width is open shape for hat in vehicle body YZ planes Section, section is replaced by straightway 101,103 with arc section 102 to be formed, comprising more than 2 arc sections, and, exist on section More than one thickness, arc section area thickness t0 are more than straightway area thickness { t1, t2 ..., ti ..., tn }, straightway area Domain quantity n is the integer more than 2；Thickness transitions region between straightway 101 and arc section 102 is provided with intermediate incline 104.

Preferably, the angle, θ scope on the body section thickness transitional region inclined-plane 104 is 15~75 °.

Embodiment：Certain automobile not uniform thickness roll-in front anti-collision beam

Referring to Fig. 4~Fig. 6, certain automobile door sill reinforcer original Cross section Design thickness is 1.6mm, right using the present invention program Its middle part carries out that design is thinned, while two side portions suitably thicken.After not uniform thickness design, suitable in guarantee performance Under the premise of, pts wt is reduced to 2.83kg by former scheme 3.28kg, realizes part loss of weight 13.7%；Part uses rolling process During production, single-piece consumable material is reduced to 3.1kg by former scheme 3.5kg, reduces by 11.4% on year-on-year basis.
