Description
Technical field
The utility model relates to AE field, particularly auto body connection structure technical field, is specially a kind of A post and top cover connecting structure.
Background technology
In a vehicle of exploitation, Body in white frame adopts steel profile space frame structure, A post and top cover side bar all adopt steel profile, A post and top cover is connected with traditional metal plate punching part, this connection structure does not ensure Joint strenght, does not ensure the bending resistance of node region, antitorque requirement simultaneously yet.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of A post and top cover connecting structure, meets the Joint strenght of A post epimere and Roof Frame, and the overall bending of vehicle body is to the requirement of node region.
The utility model is solve the problems of the technologies described above the technical scheme adopted to be:
A kind of A post and top cover connecting structure, comprise A post epimere framework section bar, top cover side bar framework section bar, Front Windshield entablatrance assembly and " T " font machine and add attaching parts, A post epimere framework section bar, top cover side bar framework section bar and Front Windshield entablatrance assembly add attaching parts by " T " font machine and link together; A post epimere framework section bar is weldingly fixed on " T " font machine and adds attaching parts lower end, and top cover side bar framework section bar is weldingly fixed on " T " font machine and adds attaching parts upper end, and Front Windshield entablatrance assembly is weldingly fixed on " T " font machine and adds attaching parts vertical end.
The improvement project of a kind of A post and top cover connecting structure, described " T " font machine adds attaching parts and is processed with different heat radiation type structures in its three ends, and its fin length coordinated with A post epimere framework section bar, top cover side bar framework section bar is not less than the half of the monolateral length of section material section; Be welded and fixed in the die cavity that the radiating gill that " T " font machine adds the upper and lower two ends of attaching parts inserts top cover side bar framework section bar and A post epimere framework section bar respectively, " T " font machine adds the radiating gill of attaching parts vertical end and Front Windshield entablatrance inner plate welding is fixed.
The utility model achieves in the vehicle body adopting steel profile space frame structure, section bar and metal plate punching part, section bar and section bar are at the Joint strenght of vehicle body Nodes, make each part uniform stressed of node region, reduce the stress on sheet metal component, meet Joint strenght, and make the bending resistance of node region, anti-twisting property gets a promotion.

In figure: 1-" T " font machine adds attaching parts, 2-A post epimere framework section bar, 3-top cover side bar framework section bar, 4-Front Windshield entablatrance assembly.
Specific embodiments
Below in conjunction with accompanying drawing, the utility model will be further described.
A kind of A post and top cover connecting structure, as shown in Figure 1, comprise A post epimere framework section bar 2, top cover side bar framework section bar 3, Front Windshield entablatrance assembly 4 and one " T " font machine to add attaching parts 1, A post epimere framework section bar 2, top cover side bar framework section bar 3 and Front Windshield entablatrance assembly 4 and add attaching parts 1 by one " T " font machine and link together.A post epimere framework section bar 2 is weldingly fixed on " T " font machine and adds attaching parts 1 lower end, and top cover side bar framework section bar 3 is weldingly fixed on " T " font machine and adds attaching parts 1 upper end, and Front Windshield entablatrance assembly 4 is weldingly fixed on " T " font machine and adds attaching parts 1 vertical end.
As shown in Figure 2, " T " font machine adds attaching parts 1 and selects cast steel, its three ends are processed with different heat radiation type structures, the fin length wherein coordinated with A post epimere framework section bar 2, top cover side bar framework section bar 3 is not less than the half of the monolateral length of section material section, vertical end radiating gill (the 3rd radiating gill) " T " font machine add Working position on attaching parts 1 select with the basic overlapping position of Front Windshield entablatrance cavity.In welding process, the radiating gill " T " font machine being added the upper and lower two ends of attaching parts inserts in the die cavity of top cover side bar framework section bar and A post epimere framework section bar respectively, intubating length is not less than the half of the monolateral length of section material section, and by CO2 gas shield arc welding, three weld parts is got up; 3rd radiating gill end and Front Windshield entablatrance inner panel are coupled together by CO2 gas shield arc welding, completes node and connect.Heat radiating fin structure reduces the weight of attaching parts, effectively improves the calorie spread in welding process simultaneously, avoids cooling strain after the welding caused because welding heat concentrates.
This structure can ensure A post epimere framework section bar 2, top cover side bar framework section bar 3, Front Windshield entablatrance assembly 4 Joint strenght at Nodes, ensure each part uniform stressed of node region, ensure that bending resistance, the anti-twisting property of node region meet car load requirement, there is good operation convenience simultaneously, ensure welding precision and the welding quality of Nodes.
