Description
Technical field
The utility model relates to auto body field, is specifically related to connection structure and the vehicle body of shrouding and after cross member under vehicle body far post.
Background technology
Be subject to the restriction of moulding, sometimes under body in white far post there is larger gluing gap in shrouding and after cross member, namely usually alleged " mouse hole ", be limited by the restriction such as product design structure and blanked part flange R angle, this place's problem can not get effective solution always, can only be optimized by coating process, affect coating process beat.
The solution solving " mouse hole " problem in prior art is from following two aspects: one, and in generation, " mouse hole " place increases brush coating station; Its two, reduce after cross member flange R angle to greatest extent, and the deburring R angle between flange R angle.As Painting Shop increases station, brush coating solves, and can add painting cost, affect application beat; As reduced flange R angle, 3mm can not be less than according to design criteria flange R, add product thickness 1mm, add the deburring R angle of two flange R angle intersections in addition, gap still cannot meet the demands, if and reducing flange R angle further, then generation stress is concentrated by R angle, flange place, easily produces and tears problem.
Utility model content
The purpose of this utility model is ensureing to eliminate " mouse hole " problem under the prerequisite by force intensity, and embodiment of the present utility model provides following technical scheme for this reason:
The connection structure of shrouding and after cross member under a kind of vehicle body far post, comprise shrouding and after cross member under vehicle body far post, described after cross member has the first flange, second flange and the 3rd flange, described first flange is adjacent with described second flange, described second flange is adjacent with described 3rd flange, the trimming line of the junction of described first flange and described second flange is straight line, under described vehicle body far post, the position of the junction of described first flange of the correspondence of shrouding and described second flange forms boss, described straight line and described boss form fit thus space under closing described after cross member and described vehicle body far post between shrouding.
Preferably, the trimming line of the junction of described second flange and described 3rd flange is tangent linear portion and circular arc line segment.
Preferably, under described vehicle body far post, the position of the junction of described second flange of the correspondence of shrouding and described 3rd flange forms additional boss, described linear portion and described arc and described additional boss form fit thus space under closing described after cross member and described vehicle body far post between shrouding.
A kind of vehicle body, described vehicle body adopts the connection structure of shrouding and after cross member under vehicle body far post as above.
The trimming line shape that embodiment of the present utility model goes out from the flange of after cross member, vehicle body far post, shrouding two aspect is considered, by the optimization of two components, non-individual considers trimming line, solve " mouse hole " problem, while elimination " mouse hole ", ensure that flange junction can not produce stress and concentrate, avoid cracking risk.

Detailed description of the invention
With reference to figure 1, the after cross member 1 that under the vehicle body far post in the present embodiment, the connection structure of shrouding and after cross member adopts has the first flange 2, second flange 3 and the 3rd flange 4.First flange 2 is adjacent with the second flange 3, and the second flange 3 is adjacent with the 3rd flange 4, and the trimming line of the junction of the first flange 2 and the second flange 3 is straight line 5, and the trimming line of the junction of the second flange 3 and the 3rd flange 4 is tangent linear portion 6 and circular arc line segment 7.
With reference to figure 2, under vehicle body far post in the present embodiment, shrouding forms boss 9 with the position of corresponding first flange 2 of shrouding 8 under the vehicle body far post that the connection structure of after cross member adopts and the junction of the second flange 3, the edge line shape of boss 9 is straight line 51 and straight line 52, and this shape matches with the after cross member 1 trimming line shape straight line 5 (being in fact also two straight lines) in Fig. 1.Under vehicle body far post, the position of correspondence second flange 3 of shrouding 8 and the junction of the 3rd flange 4 forms additional boss 10, and the edge line shape of this additional boss 10 is tangent linear portion 61 and arc 71.The linear portion 6 of the linear portion 61 of additional boss 10 and arc 71 and after cross member 1 and arc 7 form fit.
The edge line shape of boss 9 is that straight line 51 and straight line 52 match with the trimming line shape straight line 5 (being in fact also two straight lines) of Fig. 1 middle and rear cross beam 1, the linear portion 6 of the linear portion 61 of additional boss 10 and arc 71 and after cross member 1 and arc 7 form fit, the space between shrouding 8 under after cross member 1 and vehicle body far post can be closed, namely eliminate " mouse hole ".
In order to illustrate the beneficial effect of the present embodiment better, existing contrast prior art and the present embodiment carried out as shown in Figure 3 and Figure 4.
As seen from Figure 3, junction between first flange 2 ' of after cross member 1 ' of the prior art and the second flange 3 ' is designated I district, and in this position, what trimming line adopted is arc 5 ', if infinitely reduced at the R angle of this arc 5 ' in order to deratization hole, easily cause cracking.In like manner, the trimming line of what the II district, junction of the second flange 3 ' and the 3rd flange 4 ' also adopted is arc 6 ', the R angle of this trimming line can not infinitely reduce.And the I district in the present embodiment adopts is the trimming line of straight line 5, what II district adopted is tangent linear portion 6 and the combination trimming line of arc 7, and shape unlike the prior art.
As seen from Figure 4, be III district by the position mark in the I district of corresponding diagram 3 middle and rear cross beam of shrouding under vehicle body far post, and the position mark in corresponding diagram 3 Zhong II district is IV district.Under vehicle body far post of the prior art, the III district of shrouding 8 ' and IV district are dull and stereotyped; And boss 9 is played in the present embodiment Zhong III district, additional boss 10 is played in IV district, and the edge line shape of boss 9 is straight line 51 and straight line 52, and the edge line shape of additional boss 10 is tangent linear portion 61 and arc 71, and shape also unlike the prior art.
That is, the present embodiment utilizes boss 9 under vehicle body far post on shrouding 8 and additional boss 10, coordinate the I district of after cross member 1 and the trimming line alteration of form in II district, both solved " mouse hole " problem, and eliminated gap, and ensure that the intensity of junction, prevent cracking, therefore, under vehicle body adopts in the present embodiment vehicle body far post after shrouding 8 and the connection structure of after cross member 1, body quality is more reliable, and decreases the coating process in production process.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
